I see a lot of these answers rely on reading the whole text file into memory instead of taking it one chunk at a time. Here's my solution in nice modern Swift, using FileHandle to keep memory impact low:
enum MyError {
case invalidTextFormat
}
extension FileHandle {
func readLine(maxLength: Int) throws -> String {
// Read in a string of up to the maximum length
let offset = offsetInFile
let data = readData(ofLength: maxLength)
guard let string = String(data: data, encoding: .utf8) else {
throw MyError.invalidTextFormat
}
// Check for carriage returns; if none, this is the whole string
let substring: String
if let subindex = string.firstIndex(of: "\n") {
substring = String(string[string.startIndex ... subindex])
} else {
substring = string
}
// Wind back to the correct offset so that we don't miss any lines
guard let dataCount = substring.data(using: .utf8, allowLossyConversion: false)?.count else {
throw MyError.invalidTextFormat
}
try seek(toOffset: offset + UInt64(dataCount))
return substring
}
}
Note that this preserves the carriage return at the end of the line, so depending on your needs you may want to adjust the code to remove it.
Usage: simply open a file handle to your target text file and call readLine
with a suitable maximum length - 1024 is standard for plain text, but I left it open in case you know it will be shorter. Note that the command will not overflow the end of the file, so you may have to check manually that you've not reached it if you intend to parse the entire thing. Here's some sample code that shows how to open a file at myFileURL
and read it line-by-line until the end.
do {
let handle = try FileHandle(forReadingFrom: myFileURL)
try handle.seekToEndOfFile()
let eof = handle.offsetInFile
try handle.seek(toFileOffset: 0)
while handle.offsetInFile < eof {
let line = try handle.readLine(maxLength: 1024)
// Do something with the string here
}
try handle.close()
catch let error {
print("Error reading file: \(error.localizedDescription)"
}
Ruby doesn't like that you are assigning the constant inside of a method because it risks re-assignment. Several SO answers before me give the alternative of assigning it outside of a method--but in the class, which is a better place to assign it.
You can also use EXIT_SUCCESS
instead of return 0;
. The macro EXIT_SUCCESS
is actually defined as zero, but makes your program more readable.
In this particular example, it makes no difference. However, the {}
in ${}
are useful if you want to expand the variable foo
in the string
"${foo}bar"
since "$foobar"
would instead expand the variable identified by foobar
.
Curly braces are also unconditionally required when:
${array[42]}
${filename%.*}
(remove extension)"$8 $9 ${10} ${11}"
Doing this everywhere, instead of just in potentially ambiguous cases, can be considered good programming practice. This is both for consistency and to avoid surprises like $foo_$bar.jpg
, where it's not visually obvious that the underscore becomes part of the variable name.
I think this should work:
:not(.printable)
WebDriver driver=new FirefoxDriver();
driver.get("http://www.java-examples.com/java-string-examples");
Thread.sleep(3000);
//Switch to nested frame
driver.switchTo().frame("aswift_2").switchTo().frame("google_ads_frame3");
The "bind" operation is basically saying, "use this local UDP port for sending and receiving data. In other words, it allocates that UDP port for exclusive use for your application. (Same holds true for TCP sockets).
When you bind to "0.0.0.0" (INADDR_ANY
), you are basically telling the TCP/IP layer to use all available adapters for listening and to choose the best adapter for sending. This is standard practice for most socket code. The only time you wouldn't specify 0 for the IP address is when you want to send/receive on a specific network adapter.
Similarly if you specify a port value of 0 during bind, the OS will assign a randomly available port number for that socket. So I would expect for UDP multicast, you bind to INADDR_ANY on a specific port number where multicast traffic is expected to be sent to.
The "join multicast group" operation (IP_ADD_MEMBERSHIP
) is needed because it basically tells your network adapter to listen not only for ethernet frames where the destination MAC address is your own, it also tells the ethernet adapter (NIC) to listen for IP multicast traffic as well for the corresponding multicast ethernet address. Each multicast IP maps to a multicast ethernet address. When you use a socket to send to a specific multicast IP, the destination MAC address on the ethernet frame is set to the corresponding multicast MAC address for the multicast IP. When you join a multicast group, you are configuring the NIC to listen for traffic sent to that same MAC address (in addition to its own).
Without the hardware support, multicast wouldn't be any more efficient than plain broadcast IP messages. The join operation also tells your router/gateway to forward multicast traffic from other networks. (Anyone remember MBONE?)
If you join a multicast group, all the multicast traffic for all ports on that IP address will be received by the NIC. Only the traffic destined for your binded listening port will get passed up the TCP/IP stack to your app. In regards to why ports are specified during a multicast subscription - it's because multicast IP is just that - IP only. "ports" are a property of the upper protocols (UDP and TCP).
You can read more about how multicast IP addresses map to multicast ethernet addresses at various sites. The Wikipedia article is about as good as it gets:
The IANA owns the OUI MAC address 01:00:5e, therefore multicast packets are delivered by using the Ethernet MAC address range 01:00:5e:00:00:00 - 01:00:5e:7f:ff:ff. This is 23 bits of available address space. The first octet (01) includes the broadcast/multicast bit. The lower 23 bits of the 28-bit multicast IP address are mapped into the 23 bits of available Ethernet address space.
Maybe it is the case that you have your path in couple of lines, you used enter to make it? If so, then part of you paths might look like that "/\nData/" instead of "/Data/", which causes the problem. Just set it to be in one line and issue is solved!
I made this helper method in case someone need start and end position from a String.
public static TextView createLink(TextView targetTextView, String completeString,
String partToClick, ClickableSpan clickableAction) {
SpannableString spannableString = new SpannableString(completeString);
// make sure the String is exist, if it doesn't exist
// it will throw IndexOutOfBoundException
int startPosition = completeString.indexOf(partToClick);
int endPosition = completeString.lastIndexOf(partToClick) + partToClick.length();
spannableString.setSpan(clickableAction, startPosition, endPosition,
Spanned.SPAN_INCLUSIVE_EXCLUSIVE);
targetTextView.setText(spannableString);
targetTextView.setMovementMethod(LinkMovementMethod.getInstance());
return targetTextView;
}
And here is how you use it
private void initSignUp() {
String completeString = "New to Reddit? Sign up here.";
String partToClick = "Sign up";
ClickableTextUtil
.createLink(signUpEditText, completeString, partToClick,
new ClickableSpan() {
@Override
public void onClick(View widget) {
// your action
Toast.makeText(activity, "Start Sign up activity",
Toast.LENGTH_SHORT).show();
}
@Override
public void updateDrawState(TextPaint ds) {
super.updateDrawState(ds);
// this is where you set link color, underline, typeface etc.
int linkColor = ContextCompat.getColor(activity, R.color.blumine);
ds.setColor(linkColor);
ds.setUnderlineText(false);
}
});
}
It no longer suffices to start Chrome with --user-data-dir=/root/.config/google-chrome
. It simply prints Aborted
and ends (Chrome 48 on Ubuntu 12.04).
You need actually to run it as a non-root user. This you can do with
gksu -wu chrome-user google-chrome
where chrome-user
is some user you've decided should be the one to run Chrome. Your Chrome user profile will be found at ~chrome-user/.config/google-chrome
.
BTW, the old hack of changing all occurrences of geteuid
to getppid
in the chrome
binary no longer works.

I guess an img tag is needed as a child of an a tag, the following way:
<a download="YourFileName.jpeg" href="data:image/jpeg;base64,iVBO...CYII=">
<img src="data:image/jpeg;base64,iVBO...CYII="></img>
</a>
or
<a download="YourFileName.jpeg" href="/path/to/OtherFile.jpg">
<img src="/path/to/OtherFile.jpg"></img>
</a>
Only using the a tag as explained in #15 didn't worked for me with the latest version of Firefox and Chrome, but putting the same image data in both a.href and img.src tags worked for me.
From JavaScript it could be generated like this:
var data = canvas.toDataURL("image/jpeg");
var img = document.createElement('img');
img.src = data;
var a = document.createElement('a');
a.setAttribute("download", "YourFileName.jpeg");
a.setAttribute("href", data);
a.appendChild(img);
var w = open();
w.document.title = 'Export Image';
w.document.body.innerHTML = 'Left-click on the image to save it.';
w.document.body.appendChild(a);
I assume you build sample using maven.
Please check content of the JAR you're trying to run. Especially META-INFO/services
directory, file org.apache.hadoop.fs.FileSystem
. There should be list of filsystem implementation classes. Check line org.apache.hadoop.hdfs.DistributedFileSystem
is present in the list for HDFS and org.apache.hadoop.fs.LocalFileSystem
for local file scheme.
If this is the case, you have to override referred resource during the build.
Other possibility is you simply don't have hadoop-hdfs.jar
in your classpath but this has low probability. Usually if you have correct hadoop-client
dependency it is not an option.
One options will be to show the selected option above (or below) the select list like following:
HTML
<div id="selText"><span> </span></div><br/>
<select size="4" id="mySelect" style="width:65px;color:#f98ad3;">
<option value="1" selected>option 1 The Long Option</option>
<option value="2">option 2</option>
<option value="3">option 3</option>
<option value="4">option 4</option>
<option value="5">option 5 Another Longer than the Long Option ;)</option>
<option value="6">option 6</option>
</select>
JavaScript
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.2.6/jquery.min.js"
type="text/javascript"></script>
<script type="text/javascript">
$(document).ready(function(){
$("select#mySelect").change(function(){
//$("#selText").html($($(this).children("option:selected")[0]).text());
var txt = $($(this).children("option:selected")[0]).text();
$("<span>" + txt + "<br/></span>").appendTo($("#selText span:last"));
});
});
</script>
PS:- Set height of div#selText otherwise it will keep shifting select list downward.
You can also use a callable in the default field, such as:
b = models.CharField(max_length=7, default=foo)
And then define the callable:
def foo():
return 'bar'
Jordans analysis of why the $_POST-array isn't populated is correct. However, you can use
$data = file_get_contents("php://input");
to just retrieve the http body and handle it yourself. See PHP input/output streams.
From a protocol perspective this is actually more correct, since you're not really processing http multipart form data anyway. Also, use application/json as content-type when posting your request.
An alternative is to call the pip
module by using python2.7, as below:
python2.7 -m pip <commands>
For example, you could run python2.7 -m pip install <package>
to install your favorite python modules. Here is a reference: https://stackoverflow.com/a/50017310/4256346.
In case the pip module has not yet been installed for this version of python, you can run the following:
python2.7 -m ensurepip
Running this command will "bootstrap the pip installer". Note that running this may require administrative privileges (i.e. sudo
). Here is a reference: https://docs.python.org/2.7/library/ensurepip.html and another reference https://stackoverflow.com/a/46631019/4256346.
You're already doing it!
save()
will check if something in the model has changed. If it hasn't it won't run a db query.
Here's the relevant part of code in Illuminate\Database\Eloquent\Model@performUpdate
:
protected function performUpdate(Builder $query, array $options = [])
{
$dirty = $this->getDirty();
if (count($dirty) > 0)
{
// runs update query
}
return true;
}
The getDirty()
method simply compares the current attributes with a copy saved in original
when the model is created. This is done in the syncOriginal()
method:
public function __construct(array $attributes = array())
{
$this->bootIfNotBooted();
$this->syncOriginal();
$this->fill($attributes);
}
public function syncOriginal()
{
$this->original = $this->attributes;
return $this;
}
If you want to check if the model is dirty just call isDirty()
:
if($product->isDirty()){
// changes have been made
}
Or if you want to check a certain attribute:
if($product->isDirty('price')){
// price has changed
}
by XML:
<EditText
android:id="@+id/search_edit"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="@string/search"
android:imeOptions="actionSearch"
android:inputType="text" />
By Java:
editText.clearFocus();
InputMethodManager in = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
in.hideSoftInputFromWindow(searchEditText.getWindowToken(), 0);
All the same.

You are missing setting what field is the Text and Value in the SelectList itself. That is why it does a .ToString()
on each object in the list. You could think that given it is a list of SelectListItem
it should be smart enough to detect this... but it is not.
u.UserTypeOptions = new SelectList(
new List<SelectListItem>
{
new SelectListItem { Selected = true, Text = string.Empty, Value = "-1"},
new SelectListItem { Selected = false, Text = "Homeowner", Value = ((int)UserType.Homeowner).ToString()},
new SelectListItem { Selected = false, Text = "Contractor", Value = ((int)UserType.Contractor).ToString()},
}, "Value" , "Text", 1);
BTW, you can use a list of array of any type... and then just set the name of the properties that will act as Text and Value.
I think it is better to do it like this:
u.UserTypeOptions = new SelectList(
new List<SelectListItem>
{
new SelectListItem { Text = "Homeowner", Value = ((int)UserType.Homeowner).ToString()},
new SelectListItem { Text = "Contractor", Value = ((int)UserType.Contractor).ToString()},
}, "Value" , "Text");
I removed the -1 item, and the setting of each items selected true/false.
Then, in your view:
@Html.DropDownListFor(m => m.UserType, Model.UserTypeOptions, "Select one")
This way, if you set the "Select one" item, and you don't set one item as selected in the SelectList, the UserType
will be null (the UserType
need to be int?
).
If you need to set one of the SelectList items as selected, you can use:
u.UserTypeOptions = new SelectList(options, "Value" , "Text", userIdToBeSelected);
The 'more than 100% width' on the table really made it work for me.

As per discussion over here, ENOSPC
means Error No more hard-disk space available
. Reason why this much memory required by nodemon
or gulp-nodemon
(in my case) is that it was watching contents of a folder which it shouldn't. To fix that nodemon has ignore
setting that can be used to tell nodemon what not to watch. Have a look at nodemon sample config here.
I tried @abimelex solution, but in Slim 3.0, mapping the OPTIONS requests goes like:
$app = new \Slim\App();
$app->options('/books/{id}', function ($request, $response, $args) {
// Return response headers
});

The main issue with your example that you can't implicitly convert Task<T>
return types to the base T
type. You need to use the Task.Result property. Note that Task.Result will block async code, and should be used carefully.
Try this instead:
public List<int> TestGetMethod()
{
return GetIdList().Result;
}
in JSON, as in Javascript, order of object keys is meaningless, so it really doesn't matter what order they're displayed in, it is the same object.
I have to mention the path.py library, which I use very often.
Fetching the immediate subdirectories become as simple as that:
my_dir.dirs()
The full working example is:
from path import Path
my_directory = Path("path/to/my/directory")
subdirs = my_directory.dirs()
NB: my_directory still can be manipulated as a string, since Path is a subclass of string, but providing a bunch of useful methods for manipulating paths
It is compile time error for a Static Library

.xcodeproj
) with Cocoapods support, run pod update
. To fix it just close this project and open created a workspace instead (.xcworkspace
)Put this code in a file called MY_Exceptions.php in application/core folder:
<?php
if (!defined('BASEPATH'))
exit('No direct script access allowed');
/**
* Class dealing with errors as exceptions
*/
class MY_Exceptions extends CI_Exceptions
{
/**
* Force exception throwing on erros
*/
public function show_error($heading, $message, $template = 'error_general', $status_code = 500)
{
set_status_header($status_code);
$message = implode(" / ", (!is_array($message)) ? array($message) : $message);
throw new CiError($message);
}
}
/**
* Captured error from Code Igniter
*/
class CiError extends Exception
{
}
It will make all the Code Igniter errors to be treated as Exception (CiError). Then, turn all your database debug on:
$db['default']['db_debug'] = true;
There's a faster way to do that:
Arrays.hashCode(arr1) == Arrays.hashCode(arr2)
We can use the 'type' command to see file contents in cmd.

Presumably, if one wants to use an OnTouchListener
rather than an OnClickListener
, then the extra functionality of the OnTouchListener
is needed. This is a supplemental answer to show more detail of how an OnTouchListener
can be used.
Define the listener
Put this somewhere in your activity or fragment.
private View.OnTouchListener handleTouch = new View.OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
int x = (int) event.getX();
int y = (int) event.getY();
switch (event.getAction()) {
case MotionEvent.ACTION_DOWN:
Log.i("TAG", "touched down");
break;
case MotionEvent.ACTION_MOVE:
Log.i("TAG", "moving: (" + x + ", " + y + ")");
break;
case MotionEvent.ACTION_UP:
Log.i("TAG", "touched up");
break;
}
return true;
}
};
Set the listener
Set the listener in onCreate
(for an Activity) or onCreateView
(for a Fragment).
myView.setOnTouchListener(handleTouch);
Notes
getX
and getY
give you the coordinates relative to the view (that is, the top left corner of the view). They will be negative when moving above or to the left of your view. Use getRawX
and getRawY
if you want the absolute screen coordinates.x
and y
values to determine things like swipe direction.You need to use cp -t /home/shantanu/tosend
in order to tell it that the argument is the target directory and not a source. You can then change it to -exec ... +
in order to get cp
to copy as many files as possible at once.
Python library authors put the version number in <module>.__version__
. You can print it by running this on the command line:
python -c 'import keras; print(keras.__version__)'
If it's Windows terminal, enclose snippet with double-quotes like below
python -c "import keras; print(keras.__version__)"
For an inner join, WHERE
and ON
can be used interchangeably. In fact, it's possible to use ON
in a correlated subquery. For example:
update mytable
set myscore=100
where exists (
select 1 from table1
inner join table2
on (table2.key = mytable.key)
inner join table3
on (table3.key = table2.key and table3.key = table1.key)
...
)
This is (IMHO) utterly confusing to a human, and it's very easy to forget to link table1
to anything (because the "driver" table doesn't have an "on" clause), but it's legal.
A complex filter condition is better in performance perspective, but the best performance will show old fashion for loop with a standard if clause
is the best option. The difference on a small array 10 elements difference might ~ 2 times, for a large array the difference is not that big.
You can take a look on my GitHub project, where I did performance tests for multiple array iteration options
For small array 10 element throughput ops/s: For medium 10,000 elements throughput ops/s: For large array 1,000,000 elements throughput ops/s:
NOTE: tests runs on
UPDATE: Java 11 has some progress on the performance, but the dynamics stay the same
In my case image path
was wrong! So firstly, you might want to check if image path is correct :)
-L is the test for file exists and is also a symbolic link
If you do not want to test for the file being a symbolic link, but just test to see if it exists regardless of type (file, directory, socket etc) then use -e
So if file is really file and not just a symbolic link you can do all these tests and get an exit status whose value indicates the error condition.
if [ ! \( -e "${file}" \) ]
then
echo "%ERROR: file ${file} does not exist!" >&2
exit 1
elif [ ! \( -f "${file}" \) ]
then
echo "%ERROR: ${file} is not a file!" >&2
exit 2
elif [ ! \( -r "${file}" \) ]
then
echo "%ERROR: file ${file} is not readable!" >&2
exit 3
elif [ ! \( -s "${file}" \) ]
then
echo "%ERROR: file ${file} is empty!" >&2
exit 4
fi
See ?merge

Why not just try this:
right click on the table -> Script Table As -> Create To -> New Query Editor Window?
The entire list of columns are given in the script. Copy it and use the fields as necessary.
For the sake of completeness: the previous answers tell how to set the upstream branch, but not how to see it.
There are a few ways to do this:
git branch -vv
shows that info for all branches. (formatted in blue in most terminals)
cat .git/config
shows this also.
For reference:
I haven’t actually done anything with font-face
, so take this with a pinch of salt, but I don’t think there’s any way for the browser to definitively tell if a given web font installed on a user’s machine or not.
The user could, for example, have a different font with the same name installed on their machine. The only way to definitively tell would be to compare the font files to see if they’re identical. And the browser couldn’t do that without downloading your web font first.
Does Firefox download the font when you actually use it in a font
declaration? (e.g. h1 { font: 'DejaVu Serif';
)?
Use the size()
function.
>> size(A,2)
Ans =
3
The second argument specifies the dimension of which number of elements are required which will be '2' if you want the number of columns.
If you intend to knowingly keep many plots in memory, but don't want to be warned about it, you can update your options prior to generating figures.
import matplotlib.pyplot as plt
plt.rcParams.update({'figure.max_open_warning': 0})
This will prevent the warning from being emitted without changing anything about the way memory is managed.
Tiny addition to this very old thread..
If your'e evaluating an expression inside a for
/while
loop with a ternary operator, and want to continue
or break
as a result - you're gonna have a problem because both continue
&break
aren't expressions, they're statements without any value.
This will produce Uncaught SyntaxError: Unexpected token continue
for (const item of myArray) {
item.value ? break : continue;
}
If you really want a one-liner that returns a statement, you can use this instead:
for (const item of myArray) {
if (item.value) break; else continue;
}
In MySql, alice name may not work, therefore put the original column name in the CASE statement
SELECT col1 as a, CASE WHEN col1 = 'test' THEN 'yes' END as value FROM table;
Sometimes above query also may return error, I don`t know why (I faced this problem in my two different development machine). Therefore put the CASE statement into the "(...)" as below:
SELECT col1 as a, (CASE WHEN col1 = 'test' THEN 'yes' END) as value FROM table;
You can't have a link to SCSS File in your HTML page.You have to compile it down to CSS First. No there are lots of video tutorials you might want to check out. Lynda provides great video tutorials on SASS. there are also free screencasts you can google...
For official documentation visit this site http://sass-lang.com/documentation/file.SASS_REFERENCE.html And why have you chosen notepad to write Sass?? you can easily download some free text editors for better code handling.
I had tried:
string[] sample = new string[0];
But I could only insert one string into it, and then I got an exceptionOutOfBound error, so I just simply put a size for it, like
string[] sample = new string[100];
Or another way that work for me:
List<string> sample = new List<string>();
Assigning Value for list:
sample.Add(your input);
You were close. This will work:
.image { position: relative; border: 1px solid black; width: 200px; height: 200px; }
.image img { max-width: 100%; max-height: 100%; }
.overlay { position: absolute; top: 0; left: 0; right:0; bottom:0; display: none; background-color: rgba(0,0,0,0.5); }
.image:hover .overlay { display: block; }
You needed to put the :hover
on image, and make the .overlay
cover the whole image by adding right:0;
and bottom:0
.

Just try this:
DF %>% t %>% na.omit %>% t
It transposes the data frame and omits null rows which were 'columns' before transposition and then you transpose it back.
Another solution could be:
<script>
$(document)
.ready(
function() {
var wrapper = $(".myFields");
$(add_button)
.click(
function(e) {
e.preventDefault();
$(wrapper)
.append(
'.....'); //add fields here
});
$(wrapper).on("click", ".delFld", function(e) {
e.preventDefault();
$(this).parent('div').remove();
})
});
</script>

Use position: relative on the parent element.
Also note that had you not added any position attributes to any of the divs you wouldn't have seen this behavior. Juan explains further.
You can hide header like this:
<Stack.Screen name="Login" component={Login} options={{headerShown: false}} />
to escape the percent symbol, you just need %%
for example :
String.format("%1$d%%", 10)
returns "10%"
if you are using 3.6 try this
k = 250
print(f"User pressed the: {k}")
Output: User pressed the: 250
If you just want to find the position of all matches I'd like to point you to a little hack:
var haystack = 'I learned to play the Ukulele in Lebanon.',
needle = 'le',
splitOnFound = haystack.split(needle).map(function (culm)
{
return this.pos += culm.length + needle.length
}, {pos: -needle.length}).slice(0, -1); // {pos: ...} – Object wich is used as this
console.log(splitOnFound);

It might not be applikable if you have a RegExp with variable length but for some it might be helpful.
This is case sensitive. For case insensitivity use String.toLowerCase
function before.
Since Oracle 9i there are two ways or declaring a directory for use with UTL_FILE.
The older way is to set the INIT.ORA parameter UTL_FILE_DIR. We have to restart the database for a change to take affect. The value can like any other PATH variable; it accepts wildcards. Using this approach means passing the directory path...
UTL_FILE.FOPEN('c:\temp', 'vineet.txt', 'W');
The alternative approach is to declare a directory object.
create or replace directory temp_dir as 'C:\temp'
/
grant read, write on directory temp_dir to vineet
/
Directory objects require the exact file path, and don't accept wildcards. In this approach we pass the directory object name...
UTL_FILE.FOPEN('TEMP_DIR', 'vineet.txt', 'W');
The UTL_FILE_DIR is deprecated because it is inherently insecure - all users have access to all the OS directories specified in the path, whereas read and write privileges can de granted discretely to individual users. Also, with Directory objects we can be add, remove or change directories without bouncing the database.
In either case, the oracle
OS user must have read and/or write privileges on the OS directory. In case it isn't obvious, this means the directory must be visible from the database server. So we cannot use either approach to expose a directory on our local PC to a process running on a remote database server. Files must be uploaded to the database server, or a shared network drive.
If the oracle
OS user does not have the appropriate privileges on the OS directory, or if the path specified in the database does not match to an actual path, the program will hurl this exception:
ORA-29283: invalid file operation
ORA-06512: at "SYS.UTL_FILE", line 536
ORA-29283: invalid file operation
ORA-06512: at line 7
The OERR text for this error is pretty clear:
29283 - "invalid file operation"
*Cause: An attempt was made to read from a file or directory that does
not exist, or file or directory access was denied by the
operating system.
*Action: Verify file and directory access privileges on the file system,
and if reading, verify that the file exists.
apparently this problem got solved just by increasing queue size on my 3rd party smtp server. but the answer by Nip sounds like it is fairly usefull too
From Jackson 2.5, an elegant way to solve that is using the
TypeFactory.constructParametricType(Class parametrized, Class... parameterClasses) method that allows to define straigthly a Jackson JavaType
by specifying the parameterized class and its parameterized types.
Supposing you want to deserialize to Data<String>
, you can do :
// the json variable may be a String, an InputStream and so for...
JavaType type = mapper.getTypeFactory().constructParametricType(Data.class, String.class);
Data<String> data = mapper.readValue(json, type);
Note that if the class declared multiple parameterized types, it would not be really harder :
class Data <T, U> {
int found;
Class<T> hits;
List<U> list;
}
We could do :
JavaType type = mapper.getTypeFactory().constructParametricType(Data.class, String.class, Integer);
Data<String, Integer> data = mapper.readValue(json, type);
if (value){
value = (value.length > 1) ? value[0].toUpperCase() + value.substr(1).toLowerCase() : value.toUpperCase();
}
@media queries serve this purpose. Here's an example:
@media only screen and (max-width: 991px) and (min-width: 769px){
/* CSS that should be displayed if width is equal to or less than 991px and larger
than 768px goes here */
}
@media only screen and (max-width: 991px){
/* CSS that should be displayed if width is equal to or less than 991px goes here */
}
All answers say "YES" but that also depend of the project, the doc says:
One key detail about package-lock.json is that it cannot be published, and it will be ignored if found in any place other than the toplevel package.
This mean that you don't need to publish on npm your package-lock.json
for dependency but you need to use package-lock.json
in your repo to lock the version of your test dependency, build dependencies…
However, If your are using lerna for managing projects with multiple packages, you should put the package.json
only on the root of your repo, not in each subpackage are created with npm init
. You will get something like that :
.git
lerna.json
package.json
package-lock.json <--- here
packages/a/package.json
packages/a/lib/index.js
packages/b/package.json
packages/b/lib/index.js
I had a problem and found out another difference between WHERE
and HAVING
. It does not act the same way on indexed columns.
WHERE my_indexed_row = 123
will show rows and automatically perform a "ORDER ASC" on other indexed rows.
HAVING my_indexed_row = 123
shows everything from the oldest "inserted" row to the newest one, no ordering.

You can try fxCanvas: https://code.google.com/p/fxcanvas/
It implements almost all Canvas API within flash shim.
If you used...
$(function(){
function myFunc() {
// ... do something ...
};
$('#saveBtn').click(myFunc);
});
... then it will be easier to unbind later.
It is more convenient than string.Format and you can use intellisense here too.
And here is my test method:
[TestMethod]
public void StringMethodsTest_DollarSign()
{
string name = "Forrest";
string surname = "Gump";
int year = 3;
string sDollarSign = $"My name is {name} {surname} and once I run more than {year} years.";
string expectedResult = "My name is Forrest Gump and once I run more than 3 years.";
Assert.AreEqual(expectedResult, sDollarSign);
}
You can declare a @service as @Controller.
You can NOT declare an @Controller as @Service
@Service
It is regular. You are just declaring class as a Component.
@Controller
It is a little more special than Component. The dispatcher will search for @RequestMapping here. So a class annotated with @Controller, will be additionally empowered with declaring URLs through which APIs are called
The current draft of CSS Selectors Level 4 specifies structural selectors for grids. If implemented, we will be able to do things like:
th.price,
th.price || td {
text-align: right;
}
Of course, that doesn't help us today -- the other answers here offer enough practical advice for that.
both your conditions are the same:
if(s < f) { calc = f - s; n = s; }else if(f > s){ calc = s - f; n = f; }
so
if(s < f)
and
}else if(f > s){
are the same
change to
}else if(f < s){
You can track by $index
if your data source has duplicate identifiers
e.g.: $scope.dataSource: [{id:1,name:'one'}, {id:1,name:'one too'}, {id:2,name:'two'}]
You can't iterate this collection while using 'id' as identifier (duplicate id:1).
WON'T WORK:
<element ng-repeat="item.id as item.name for item in dataSource">
// something with item ...
</element>
but you can, if using track by $index
:
<element ng-repeat="item in dataSource track by $index">
// something with item ...
</element>
Instead of checking for the __iter__
attribute, you could check for the __len__
attribute, which is implemented by every python builtin iterable, including strings.
>>> hasattr(1, "__len__")
False
>>> hasattr(1.3, "__len__")
False
>>> hasattr("a", "__len__")
True
>>> hasattr([1,2,3], "__len__")
True
>>> hasattr({1,2}, "__len__")
True
>>> hasattr({"a":1}, "__len__")
True
>>> hasattr(("a", 1), "__len__")
True
None-iterable objects would not implement this for obvious reasons. However, it does not catch user-defined iterables that do not implement it, nor do generator expressions, which iter
can deal with. However, this can be done in a line, and adding a simple or
expression checking for generators would fix this problem. (Note that writing type(my_generator_expression) == generator
would throw a NameError
. Refer to this answer instead.)
You can use GeneratorType from types:
>>> import types >>> types.GeneratorType <class 'generator'> >>> gen = (i for i in range(10)) >>> isinstance(gen, types.GeneratorType) True
--- accepted answer by utdemir
(This makes it useful for checking if you can call len
on the object though.)
The accepted answer is strongly incorrect:
For these dates: ldate = 2020-08-30 and rdate = 2020-08-01, we have one month, but the accepted answer returns 0.
For these dates: ldate = 2020-08-30 and rdate = 2020-10-01, we have three months, but the accepted answer returns -2.
Here is the correct method (maybe not the unique method, but correct) to calculate the quantity of months between two dates:
You don't have to check which date is lower than other.
An interval from the first day to the last day of month is counted as a month.
public static int GetMontsBetween(DateTime date1, DateTime date2)
{
int monthCount = 0;
int direction = date1 < date2 ? 1 : -1;
date2 = date2.AddDays(direction);
while (date1.Year != date2.Year || date1.Month != date2.Month)
{
date1 = date1.AddMonths(direction);
monthCount++;
}
return monthCount;
}
In my specific case I tried to create a React Native app using the react-native init installation process, when I encountered the discussed problem.
FAILURE: Build failed with an exception.
* What went wrong:
A problem occurred configuring project ':app'.
> SDK location not found. Define location with an ANDROID_SDK_ROOT environment variable or by setting the sdk.dir path in your project's local properties file at 'C:\Users\***\android\local.properties'.
I add this, because when developing an android app using react native, the 'root directory' to which so many answers refer, is actually the root of the android folder (and not the project's root folder, where App.js resides). This is also made clear by the directory marked in the error message.
To solve it, just add a local.properties file to the android folder, and type:
sdk.dir=C:/Users/{user name}/AppData/Local/Android/Sdk
Be sure to add the local disk's reference ('C:/'), because it did not work otherwise in my case.
Below css works for me on IE 11 and Edge, no JS needed.
scaleY(1)
does the trick here. Seems the simplest solution.
.box {
max-height: 360px;
transition: all 0.3s ease-out;
transform: scaleY(1);
}
.box.collapse {
max-height: 0;
}
The Android support library can be imported within gradle in the dependencies :
compile 'com.android.support:design:22.2.0'
It should be included within GradlePlease! And as an example to use it:
<android.support.design.widget.TextInputLayout
android:id="@+id/to_text_input_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<AutoCompleteTextView
android:id="@+id/autoCompleteTextViewTo"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:hint="To"
android:layout_marginTop="45dp"
/>
</android.support.design.widget.TextInputLayout>
Btw, the editor may not understand that AutoCompleteTextView is allowed within TextInputLayout.
No, z is undefined. item contains a list of integers.
I think what you're trying to do is this:
#z defined elsewhere
item = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
for i in item:
if i not in z: print i
As has been stated in other answers, you may want to try using sets.
From the future
A simple generic function I normally use.
const promisify = (fn, ...args) => {
return new Promise((resolve, reject) => {
fn(...args, (err, data) => {
if (err) {
return reject(err);
}
resolve(data);
});
});
};
How to use it
promisify(fn, arg1, arg2)
You are probably not looking to this answer, but this will help understand the inner workings of the available utils
a[0]
isn't an array, it's the first element of a
and therefore has no dimensions.
Try using a[0:1]
instead, which will return the first element of a
inside a single item array.
Give a class to your cell containing the icon
<td class="icon"><i class="icon-ok"></i></td>
and then
.icon{
text-align: center;

This is a solution to make the keyboard go away when hit return
in any textfield, by adding code in one place (so don't have to add a handler for each textfield):
consider this scenario:
i have a viewcontroller
with two textfields (username and password).
and the viewcontroller
implements UITextFieldDelegate
protocol
i do this in viewDidLoad
- (void)viewDidLoad
{
[super viewDidLoad];
username.delegate = self;
password.delegate = self;
}
and the viewcontroller implements the optional method as
- (BOOL)textFieldShouldReturn:(UITextField *)textField
{
[textField resignFirstResponder];
return YES;
}
and irrespective of the textfield you are in, as soon as i hit return
in the keyboard, it gets dismissed!
In your case, the same would work as long as you set all the textfield's delegate to self and implement textFieldShouldReturn
Look at array_intersect().
$containsSearch = count(array_intersect($search_this, $all)) == count($search_this);
The accepted answer is out of date; nowadays you can simply add enctype="application/json"

If you want to add a click listener in chrome console, use this

In addition to given answer, it's worth noting that compiler is not required to initialize constexpr
variable at compile time, knowing that the difference between constexpr
and static constexpr
is that to use static constexpr
you ensure the variable is initialized only once.
Following code demonstrates how constexpr
variable is initialized multiple times (with same value though), while static constexpr
is surely initialized only once.
In addition the code compares the advantage of constexpr
against const
in combination with static
.
#include <iostream>
#include <string>
#include <cassert>
#include <sstream>
const short const_short = 0;
constexpr short constexpr_short = 0;
// print only last 3 address value numbers
const short addr_offset = 3;
// This function will print name, value and address for given parameter
void print_properties(std::string ref_name, const short* param, short offset)
{
// determine initial size of strings
std::string title = "value \\ address of ";
const size_t ref_size = ref_name.size();
const size_t title_size = title.size();
assert(title_size > ref_size);
// create title (resize)
title.append(ref_name);
title.append(" is ");
title.append(title_size - ref_size, ' ');
// extract last 'offset' values from address
std::stringstream addr;
addr << param;
const std::string addr_str = addr.str();
const size_t addr_size = addr_str.size();
assert(addr_size - offset > 0);
// print title / ref value / address at offset
std::cout << title << *param << " " << addr_str.substr(addr_size - offset) << std::endl;
}
// here we test initialization of const variable (runtime)
void const_value(const short counter)
{
static short temp = const_short;
const short const_var = ++temp;
print_properties("const", &const_var, addr_offset);
if (counter)
const_value(counter - 1);
}
// here we test initialization of static variable (runtime)
void static_value(const short counter)
{
static short temp = const_short;
static short static_var = ++temp;
print_properties("static", &static_var, addr_offset);
if (counter)
static_value(counter - 1);
}
// here we test initialization of static const variable (runtime)
void static_const_value(const short counter)
{
static short temp = const_short;
static const short static_var = ++temp;
print_properties("static const", &static_var, addr_offset);
if (counter)
static_const_value(counter - 1);
}
// here we test initialization of constexpr variable (compile time)
void constexpr_value(const short counter)
{
constexpr short constexpr_var = constexpr_short;
print_properties("constexpr", &constexpr_var, addr_offset);
if (counter)
constexpr_value(counter - 1);
}
// here we test initialization of static constexpr variable (compile time)
void static_constexpr_value(const short counter)
{
static constexpr short static_constexpr_var = constexpr_short;
print_properties("static constexpr", &static_constexpr_var, addr_offset);
if (counter)
static_constexpr_value(counter - 1);
}
// final test call this method from main()
void test_static_const()
{
constexpr short counter = 2;
const_value(counter);
std::cout << std::endl;
static_value(counter);
std::cout << std::endl;
static_const_value(counter);
std::cout << std::endl;
constexpr_value(counter);
std::cout << std::endl;
static_constexpr_value(counter);
std::cout << std::endl;
}
Possible program output:
value \ address of const is 1 564
value \ address of const is 2 3D4
value \ address of const is 3 244
value \ address of static is 1 C58
value \ address of static is 1 C58
value \ address of static is 1 C58
value \ address of static const is 1 C64
value \ address of static const is 1 C64
value \ address of static const is 1 C64
value \ address of constexpr is 0 564
value \ address of constexpr is 0 3D4
value \ address of constexpr is 0 244
value \ address of static constexpr is 0 EA0
value \ address of static constexpr is 0 EA0
value \ address of static constexpr is 0 EA0
As you can see yourself constexpr
is initilized multiple times (address is not the same) while static
keyword ensures that initialization is performed only once.
Does this work? Untested but should get the point across.
UPDATE FUNCTIONS
SET Func_TaxRef =
(
SELECT Min(TAX.Tax_Code) AS MinOfTax_Code
FROM TAX, FUNCTIONS F1
WHERE F1.Func_Pure <= [Tax_ToPrice]
AND F1.Func_Year=[Tax_Year]
AND F1.Func_ID = FUNCTIONS.Func_ID
GROUP BY F1.Func_ID;
)
Basically for each row in FUNCTIONS, the subquery determines the minimum current tax code and sets FUNCTIONS.Func_TaxRef to that value. This is assuming that FUNCTIONS.Func_ID is a Primary or Unique key.
I wanted something to return the address regardless of whether or not wifi was enabled, so the chosen solution didn't work for me. I used another call I found on some forum after some tweaking. I ended up with the following (excuse my rusty C ) :
#include <sys/types.h>
#include <stdio.h>
#include <string.h>
#include <sys/socket.h>
#include <net/if_dl.h>
#include <ifaddrs.h>
char* getMacAddress(char* macAddress, char* ifName) {
int success;
struct ifaddrs * addrs;
struct ifaddrs * cursor;
const struct sockaddr_dl * dlAddr;
const unsigned char* base;
int i;
success = getifaddrs(&addrs) == 0;
if (success) {
cursor = addrs;
while (cursor != 0) {
if ( (cursor->ifa_addr->sa_family == AF_LINK)
&& (((const struct sockaddr_dl *) cursor->ifa_addr)->sdl_type == IFT_ETHER) && strcmp(ifName, cursor->ifa_name)==0 ) {
dlAddr = (const struct sockaddr_dl *) cursor->ifa_addr;
base = (const unsigned char*) &dlAddr->sdl_data[dlAddr->sdl_nlen];
strcpy(macAddress, "");
for (i = 0; i < dlAddr->sdl_alen; i++) {
if (i != 0) {
strcat(macAddress, ":");
}
char partialAddr[3];
sprintf(partialAddr, "%02X", base[i]);
strcat(macAddress, partialAddr);
}
}
cursor = cursor->ifa_next;
}
freeifaddrs(addrs);
}
return macAddress;
}
And then I would call it asking for en0, as follows:
char* macAddressString= (char*)malloc(18);
NSString* macAddress= [[NSString alloc] initWithCString:getMacAddress(macAddressString, "en0")
encoding:NSMacOSRomanStringEncoding];
free(macAddressString);
Basically, the third parameter in loggedIn
should not be an integer, it should be an object of some kind, but we can't know for sure because you did not name the parameters in the method call. Provide the method signature so we can see for sure. Perhaps it takes an NSNumber
or something.
You can simply traverse through the object and return if a match is found.
Here is the code:
returnKeyforValue : function() {
var JsonObj= { "one":1, "two":2, "three":3, "four":4, "five":5 };
for (key in JsonObj) {
if(JsonObj[key] === "Keyvalue") {
return key;
}
}
}
typeof
is an operator to obtain a type known at compile-time (or at least a generic type parameter). The operand of typeof
is always the name of a type or type parameter - never an expression with a value (e.g. a variable). See the C# language specification for more details.
GetType()
is a method you call on individual objects, to get the execution-time type of the object.
Note that unless you only want exactly instances of TextBox
(rather than instances of subclasses) you'd usually use:
if (myControl is TextBox)
{
// Whatever
}
Or
TextBox tb = myControl as TextBox;
if (tb != null)
{
// Use tb
}
An alternative way to code Brettski's answer, with which I otherwise agree entirely, might be
With New FileSystemObject
If .FileExists(yourFilePath) Then
.DeleteFile yourFilepath
End If
End With
Same effect but fewer (well, none at all) variable declarations.
The FileSystemObject is a really useful tool and well worth getting friendly with. Apart from anything else, for text file writing it can actually sometimes be faster than the legacy alternative, which may surprise a few people. (In my experience at least, YMMV).

If you want to undo all files that was applied assume unchanged with any status, not only cached (git marks them by character in lower case), you can use the following command:
git ls-files -v | grep '^[a-z]' | cut -c 3- | tr '\012' '\000' | xargs -0 git update-index --no-assume-unchanged
git ls-files -v
will print all files with their statusgrep '^[a-z]'
will filter files and select only assume unchangedcut -c 3-
will remove status and leave only paths, cutting from the 3-rd character to the endtr '\012' '\000'
will replace end of line character (\012) to zero character (\000)xargs -0 git update-index --no-assume-unchanged
will pass all paths separated by zero character to git update-index --no-assume-unchanged

You can prevent interactive prompt without disabling StrictHostKeyChecking
(which is insecure).
Incorporate the following logic into your script:
if [ -z "$(ssh-keygen -F $IP)" ]; then
ssh-keyscan -H $IP >> ~/.ssh/known_hosts
fi
It checks if public key of the server is in known_hosts
. If not, it requests public key from the server and adds it to known_hosts
.
In this way you are exposed to Man-In-The-Middle attack only once, which may be mitigated by:
if you are using windows try to pass encoding='latin1', encoding='iso-8859-1' or encoding='cp1252' example:
csv_data = pd.read_csv(csvpath,encoding='iso-8859-1')
print(print(soup.encode('iso-8859-1')))
There is my example. Selected button in the middle on the list Controller. config >>>
$scope.pagination = {total: null, pages: [], config: {count: 10, page: 1, size: 7}};
Logic for pagination:
/*
Pagination
*/
$scope.$watch('pagination.total', function (total) {
if(!total || total <= $scope.pagination.config.count) return;
_setPaginationPages(total);
});
function _setPaginationPages(total) {
var totalPages = Math.ceil(total / $scope.pagination.config.count);
var pages = [];
var start = $scope.pagination.config.page - Math.floor($scope.pagination.config.size/2);
var finish = null;
if((start + $scope.pagination.config.size - 1) > totalPages){
start = totalPages - $scope.pagination.config.size;
}
if(start <= 0) {
start = 1;
}
finish = start + $scope.pagination.config.size - 1;
if(finish > totalPages){
finish = totalPages;
}
for (var i = start; i <= finish; i++) {
pages.push(i);
}
$scope.pagination.pages = pages;
}
$scope.$watch("pagination.config.page", function(page){
_setPaginationPages($scope.pagination.total);
_getRespondents($scope.pagination.config);
});
and my view on bootstap
<ul ng-class="{hidden: pagination.total == 0}" class="pagination">

So after a long time of playing around with AccessibilityServices, window insets, screen height detection, etc, I think I found a way to do this.
Disclaimer: it uses a hidden method in Android, meaning it might not be consistent. However, in my testing, it seems to work.
The method is InputMethodManager#getInputMethodWindowVisibleHeight(), and it's existed since Lollipop (5.0).
Calling that returns the height, in pixels, of the current keyboard. In theory, a keyboard shouldn't be 0 pixels tall, so I did a simple height check (in Kotlin):
val imm by lazy { context.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager }
if (imm.inputMethodWindowVisibleHeight > 0) {
//keyboard is shown
else {
//keyboard is hidden
}
I use Android Hidden API to avoid reflection when I call hidden methods (I do that a lot for the apps I develop, which are mostly hacky/tuner apps), but this should be possible with reflection as well:
val imm by lazy { context.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager }
val windowHeightMethod = InputMethodManager::class.java.getMethod("getInputMethodWindowVisibleHeight")
val height = windowHeightMethod.invoke(imm) as Int
//use the height val in your logic
FWIW, git rebase interactive now has a "reword" option, which makes this much less painful!

I looked for a C/C++ API for Google Voice for quite a while and never found anything close (the closest was a C# API). Since I really needed it, I decided to just write one myself:
http://github.com/mastermind202/GoogleVoice
I hope others find it useful. Feedback and suggestions welcome.
First thing first, button()
is a jQuery ui function to create a button widget which has nothing to do with jQuery core, it just styles the button.
So if you want to use the widget add jQuery ui's javascript and CSS files or alternatively remove it, like this:
$("#filter").click(function(){
alert('clicked!');
});
Another thing that might have caused you the problem is if you didn't wait for the input to be rendered and wrote the code before the input. jQuery has the ready function, or it's alias $(func)
which execute the callback once the DOM is ready.
Usage:
$(function(){
$("#filter").click(function(){
alert('clicked!');
});
});
So even if the order is this it will work:
$(function(){
$("#filter").click(function(){
alert('clicked!');
});
});
<input type="button" id="filter" name="filter" value="Filter" />
Incidentally, Windows no longer knows how to correctly convert UTC to U.S. local time for certain dates in March/April or October/November of past years. UTC-based timestamps from those dates are now somewhat nonsensical. It would be very icky for the OS to simply refuse to handle any timestamps prior to the U.S. government's latest set of DST rules, so it simply handles some of them wrong. SQL Server refuses to process dates before 1753 because lots of extra special logic would be required to handle them correctly and it doesn't want to handle them wrong.

Make sure you define the function before you call it.
See RFC 2822, section 2.1.1 to start.
There are two limits that this standard places on the number of characters in a line. Each line of characters MUST be no more than 998 characters, and SHOULD be no more than 78 characters, excluding the CRLF.
As the RFC states later, you can work around this limit (not that you should) by folding the subject over multiple lines.
Each header field is logically a single line of characters comprising the field name, the colon, and the field body. For convenience however, and to deal with the 998/78 character limitations per line, the field body portion of a header field can be split into a multiple line representation; this is called "folding". The general rule is that wherever this standard allows for folding white space (not simply WSP characters), a CRLF may be inserted before any WSP. For example, the header field:
Subject: This is a test
can be represented as:
Subject: This is a test
The recommendation for no more than 78 characters in the subject header sounds reasonable. No one wants to scroll to see the entire subject line, and something important might get cut off on the right.
Let's take a normal list (implemented by the ArrayList class) and make it synchronized. This is shown in the SynchronizedListExample class. We pass the Collections.synchronizedList method a new ArrayList of Strings. The method returns a synchronized List of Strings. //Here is SynchronizedArrayList class
package com.mnas.technology.automation.utility;
import java.util.ArrayList;
import java.util.Collections;
import java.util.Iterator;
import java.util.List;
import org.apache.log4j.Logger;
/**
*
* @author manoj.kumar
* @email [email protected]
*
*/
public class SynchronizedArrayList {
static Logger log = Logger.getLogger(SynchronizedArrayList.class.getName());
public static void main(String[] args) {
List<String> synchronizedList = Collections.synchronizedList(new ArrayList<String>());
synchronizedList.add("Aditya");
synchronizedList.add("Siddharth");
synchronizedList.add("Manoj");
// when iterating over a synchronized list, we need to synchronize access to the synchronized list
synchronized (synchronizedList) {
Iterator<String> iterator = synchronizedList.iterator();
while (iterator.hasNext()) {
log.info("Synchronized Array List Items: " + iterator.next());
}
}
}
}
Notice that when iterating over the list, this access is still done using a synchronized block that locks on the synchronizedList object. In general, iterating over a synchronized collection should be done in a synchronized block
When the 2d-array (or nd-array) is C- or F-contiguous, then this task of mapping a function onto a 2d-array is practically the same as the task of mapping a function onto a 1d-array - we just have to view it that way, e.g. via np.ravel(A,'K')
.
Possible solution for 1d-array have been discussed for example here.
However, when the memory of the 2d-array isn't contiguous, then the situation a little bit more complicated, because one would like to avoid possible cache misses if axis are handled in wrong order.
Numpy has already a machinery in place to process axes in the best possible order. One possibility to use this machinery is np.vectorize
. However, numpy's documentation on np.vectorize
states that it is "provided primarily for convenience, not for performance" - a slow python function stays a slow python function with the whole associated overhead! Another issue is its huge memory-consumption - see for example this SO-post.
When one wants to have a performance of a C-function but to use numpy's machinery, a good solution is to use numba for creation of ufuncs, for example:
# runtime generated C-function as ufunc
import numba as nb
@nb.vectorize(target="cpu")
def nb_vf(x):
return x+2*x*x+4*x*x*x
It easily beats np.vectorize
but also when the same function would be performed as numpy-array multiplication/addition, i.e.
# numpy-functionality
def f(x):
return x+2*x*x+4*x*x*x
# python-function as ufunc
import numpy as np
vf=np.vectorize(f)
vf.__name__="vf"
See appendix of this answer for time-measurement-code:
Numba's version (green) is about 100 times faster than the python-function (i.e. np.vectorize
), which is not surprising. But it is also about 10 times faster than the numpy-functionality, because numbas version doesn't need intermediate arrays and thus uses cache more efficiently.
While numba's ufunc approach is a good trade-off between usability and performance, it is still not the best we can do. Yet there is no silver bullet or an approach best for any task - one has to understand what are the limitation and how they can be mitigated.
For example, for transcendental functions (e.g. exp
, sin
, cos
) numba doesn't provide any advantages over numpy's np.exp
(there are no temporary arrays created - the main source of the speed-up). However, my Anaconda installation utilizes Intel's VML for vectors bigger than 8192 - it just cannot do it if memory is not contiguous. So it might be better to copy the elements to a contiguous memory in order to be able to use Intel's VML:
import numba as nb
@nb.vectorize(target="cpu")
def nb_vexp(x):
return np.exp(x)
def np_copy_exp(x):
copy = np.ravel(x, 'K')
return np.exp(copy).reshape(x.shape)
For the fairness of the comparison, I have switched off VML's parallelization (see code in the appendix):
As one can see, once VML kicks in, the overhead of copying is more than compensated. Yet once data becomes too big for L3 cache, the advantage is minimal as task becomes once again memory-bandwidth-bound.
On the other hand, numba could use Intel's SVML as well, as explained in this post:
from llvmlite import binding
# set before import
binding.set_option('SVML', '-vector-library=SVML')
import numba as nb
@nb.vectorize(target="cpu")
def nb_vexp_svml(x):
return np.exp(x)
and using VML with parallelization yields:
numba's version has less overhead, but for some sizes VML beats SVML even despite of the additional copying overhead - which isn't a bit surprise as numba's ufuncs aren't parallelized.

Both if (one.length() > 0) {}
and if (!"".equals(one)) {}
will check against an empty foo parameter, and an empty parameter is what you'd get if the the form is submitted with no value in the foo
text field.
If there's any chance you can use the Expression Language to handle the parameter, you could
access it with empty param.foo
in an expression.

For me the issue was a conflict between several versions of the same library. The Eclipse assist was using an older version than maven.
I had to go to the .m2 directory and delete the unwanted lib version + restart eclipse.

I'm not sure it's a standard construct, but I think you should have a look on "negative lookahead" (which writes : "?!", without the quotes). It's far easier than all answers in this thread, including the accepted one.
Example : Regex : "^(?!123)[0-9]*\w" Captures any string beginning by digits followed by letters, UNLESS if "these digits" are 123.
http://msdn.microsoft.com/en-us/library/az24scfc%28v=vs.110%29.aspx#grouping_constructs (microsoft page, but quite comprehensive) for lookahead / lookbehind
PS : it works well for me (.Net). But if I'm wrong on something, please let us know. I find this construct very simple and effective, so I'm surprised of the accepted answer.
You'll need to use System.Threading.Thread.Sleep(number of milliseconds).

It is always painful for developers to with ng-options. For example: Getting an empty/blank selected value in the select tag. Especially when dealing with JSON objects in ng-options, it becomes more tedious. Here I have done some exercises on that.
Objective: Iterate array of JSON objects through ng-option and set selected first element.
Data:
someNames = [{"id":"1", "someName":"xyz"}, {"id":"2", "someName":"abc"}]
In the select tag I had to show xyz and abc, where xyz must be selected without much effort.
<pre class="default prettyprint prettyprinted" style=""><code>
<select class="form-control" name="test" style="width:160px" ng-options="name.someName for name in someNames" ng-model="testModel.test" ng-selected = "testModel.test = testModel.test || someNames[0]">
</select>
</code></pre>
By above code sample, you might get out of this exaggeration.

How about following commands?

net stop "<service name>"
As you can probably see from the multitude of different (and often mutually exclusive) answers, it depends on who you ask. In some arenas, the terms are synonymous. Or they might each refer to two similar concepts:
In either case, the intention is to allow the program to not be blocked waiting for a slow process to complete - how the program is expected to respond is the only real difference. Which term refers to which also changes from programmer to programmer, language to language, or platform to platform. Or the terms may refer to completely different concepts (such as the use of synchronous/asynchronous in relation to thread programming).
Sorry, but I don't believe there is a single right answer that is globally true.
Use:
File.Exists(path)
MSDN: http://msdn.microsoft.com/en-us/library/system.io.file.exists.aspx
Edit: In System.IO
Example:
Creating external table to store the query results at '/user/myName/projectA_additionaData/'
CREATE EXTERNAL TABLE additionaData
(
ID INT,
latitude STRING,
longitude STRING
)
COMMENT 'Additional Data gathered by joining of the identified cities with latitude and longitude data'
ROW FORMAT DELIMITED FIELDS
TERMINATED BY ',' STORED AS TEXTFILE location '/user/myName/projectA_additionaData/';
Feeding the query results into the temp table

From man clock:
The clock() function returns an approximation of processor time used by the program.
So there is no indication you should treat it as milliseconds. Some standards require precise value of CLOCKS_PER_SEC
, so you could rely on it, but I don't think it is advisable.
Second thing is that, as @unwind stated, it is not float/double. Man times suggests that will be an int.
Also note that:
this function will return the same value approximately every 72 minutes
And if you are unlucky you might hit the moment it is just about to start counting from zero, thus getting negative or huge value (depending on whether you store the result as signed or unsigned value).
This:
printf("\n\n%6.3f", stop);
Will most probably print garbage as treating any int as float is really not defined behaviour (and I think this is where most of your problem comes). If you want to make sure you can always do:
printf("\n\n%6.3f", (double) stop);
Though I would rather go for printing it as long long int
at first:
printf("\n\n%lldf", (long long int) stop);
You just forgot the quotes. Change your code according to this:
<button type="button" onClick = "document.getElementById('chartdiv').style.height = '200px'">Click Me!</button>
should work.

maxConnections When this number has been reached, the server will accept, but not process, one further connection. once the limit has been reached, the operating system may still accept connections based on the acceptCount setting. (The maximum queue length for incoming connection requests when all possible request processing threads are in use. Any requests received when the queue is full will be refused. The default value is 100.) For BIO the default is the value of maxThreads unless an Executor is used in which case the default will be the value of maxThreads from the executor. For NIO and NIO2 the default is 10000. For APR/native, the default is 8192. Note that for APR/native on Windows, the configured value will be reduced to the highest multiple of 1024 that is less than or equal to maxConnections. This is done for performance reasons.
maxThreads
The maximum number of request processing threads to be created by this Connector, which therefore determines the maximum number of simultaneous requests that can be handled. If not specified, this attribute is set to 200. If an executor is associated with this connector, this attribute is ignored as the connector will execute tasks using the executor rather than an internal thread pool.
Does it mean that I'm blocking reading any input from the Server/Client for this socket for 2000 millisecond and after this time the socket is ready to read data?
No, it means that if no data arrives within 2000ms a SocketTimeoutException
will be thrown.
What does it mean timeout expire?
It means the 2000ms (in your case) elapses without any data arriving.
What is the option which must be enabled prior to blocking operation?
There isn't one that 'must be' enabled. If you mean 'may be enabled', this is one of them.
Infinite Timeout menas that the socket does't read anymore?
What a strange suggestion. It means that if no data ever arrives you will block in the read forever.
You can also pass in a variable and/or object if you wanted to.
var str1:String = "John"
var str2:String = "Bob"
var myArray = ["Steve", "Bill", "Linus", "Bret"]
//add to the end of the array with append
myArray.append(str1)
myArray.append(str2)
To add them to the front:
//use 'insert' instead of append
myArray.insert(str1, atIndex:0)
myArray.insert(str2, atIndex:0)
//Swift 3
myArray.insert(str1, at: 0)
myArray.insert(str2, at: 0)

In SQL Server, you can use this query:

Colin is correct that a profile should be used. However, his answer hard-codes the target directory in the profile. An alternate solution would be to add a profile like this:
<profile>
<id>alternateBuildDir</id>
<activation>
<property>
<name>alt.build.dir</name>
</property>
</activation>
<build>
<directory>${alt.build.dir}</directory>
</build>
</profile>
Doing so would have the effect of changing the build directory to whatever is given by the alt.build.dir property, which can be given in a POM, in the user's settings, or on the command line. If the property is not present, the compilation will happen in the normal target directory.

If you can use C#6 or higher, you can benefit from Interpolated Strings and rewrite @Ari Roth's solution like this:

public static string ToHexString(this Color c) => $"#{c.R:X2}{c.G:X2}{c.B:X2}";
public static string ToRgbString(this Color c) => $"RGB({c.R}, {c.G}, {c.B})";
}

to use them as extensions methods.string
instead of the class name.A textarea

sub-elements.
You only need to parse String values using Double
String someValue= "52.23";
Double doubleVal = Double.parseDouble(someValue);
System.out.println(doubleVal);

I got sick of constantly seeing messages about the various library.xml
files that Gradle creates or deletes in /.idea
. The build.gradle
will run on the developers's local when they first check out the project, so why do those XML files need to be versioned? Android Studio will also generate the rest of /.idea

is versioned a new user will have to name the project exactly the same as it was when committed. Since this is also a generated file, why version it in the first place?
The local.properties
files points to an absolute path on the file system for the SDK, so it definitely shouldn't be versioned.
Edit 1: Added .gradle
to ignore the gradle caching stuff that should not be versioned (thanks Vasily Makarov).
Edit 2: Added .DS_Store
now that I am using Mac. This folder is Mac specific and should not be versioned.
Additional note: You probably also want to add a directory to put your signing keys in when building a release version.
For copy/paste convenience:
.gradle
/build
/.idea
*.iml
local.properties
.DS_Store
A quick update to Michael's excellent answer above.
For Rails 4.0+ you need to put your sort in a block like this:
class Book < ActiveRecord::Base
default_scope { order('created_at DESC') }
end
Notice that the order statement is placed in a block denoted by the curly braces.
They changed it because it was too easy to pass in something dynamic (like the current time). This removes the problem because the block is evaluated at runtime. If you don't use a block you'll get this error:
Support for calling #default_scope without a block is removed. For example instead of
default_scope where(color: 'red')
, please usedefault_scope { where(color: 'red') }
. (Alternatively you can just redefine self.default_scope.)
As @Dan mentions in his comment below, you can do a more rubyish syntax like this:
class Book < ActiveRecord::Base
default_scope { order(created_at: :desc) }
end
or with multiple columns:
class Book < ActiveRecord::Base
default_scope { order({begin_date: :desc}, :name) }
end
Thanks @Dan!
Pickle uses different protocols
to convert your data to a binary stream.
In python 2 there are 3 different protocols (0
, 1
, 2
) and the default is 0
.
In python 3 there are 5 different protocols (0
, 1
, 2
, 3
, 4
) and the default is 3
.
You must specify in python 3 a protocol lower than 3
in order to be able to load the data in python 2. You can specify the protocol
parameter when invoking pickle.dump
.
The "BIGINT(20)" specification isn't a digit limit. It just means that when the data is displayed, if it uses less than 20 digits it will be left-padded with zeros. 2^64 is the hard limit for the BIGINT type, and has 20 digits itself, hence BIGINT(20) just means everything less than 10^20 will be left-padded with spaces on display.
I found the answer on the web:
Dim fsT As Object
Set fsT = CreateObject("ADODB.Stream")
fsT.Type = 2 'Specify stream type - we want To save text/string data.
fsT.Charset = "utf-8" 'Specify charset For the source text data.
fsT.Open 'Open the stream And write binary data To the object
fsT.WriteText "special characters: äöüß"
fsT.SaveToFile sFileName, 2 'Save binary data To disk
Certainly not as I expected...
The best way to work with args for your winforms app is to use
string[] args = Environment.GetCommandLineArgs();
You can probably couple this with the use of an enum to solidify the use of the array througout your code base.
"And you can use this anywhere in your application, you aren’t just restricted to using it in the main() method like in a console application."
Found at:HERE
If you are trying to allocate space for an array of pointers, such as
char** my_array_of_strings; // or some array of pointers such as int** or even void**
then you will need to consider word size (8 bytes in a 64-bit system, 4 bytes in a 32-bit system) when allocating space for n pointers. The size of a pointer is the same of your word size.
So while you may wish to allocate space for n pointers, you are actually going to need n times 8 or 4 (for 64-bit or 32-bit systems, respectively)
To avoid overflowing your allocated memory for n elements of 8 bytes:
my_array_of_strings = (char**) malloc( n * 8 ); // for 64-bit systems
my_array_of_strings = (char**) malloc( n * 4 ); // for 32-bit systems
This will return a block of n pointers, each consisting of 8 bytes (or 4 bytes if you're using a 32-bit system)
I have noticed that Linux will allow you to use all n pointers when you haven't compensated for word size, but when you try to free that memory it realizes its mistake and it gives out that rather nasty error. And it is a bad one, when you overflow allocated memory, many security issues lie in wait.

DHT nodes have unique identifiers, termed, Node ID. Node IDs are chosen at random from the same 160-bit space as BitTorrent info-hashes. Closeness is measured by comparing Node ID's routing tables, the closer the Node, the more detailed, resulting in optimal
What then makes them more optimal than it's predecessor "Kademlia" which used simple unsigned integers: distance(A,B) = |A xor B| Smaller values are closer. XOR. Besides not being secure, its logic was flawed.
If your client supports DHT, there are 8-bytes reserved in which contains 0x09 followed by a 2-byte payload with the UDP Port and DHT node. If the handshake is successful the above will continue.
I am calling the json on login button click
@IBAction func loginClicked(sender : AnyObject){
var request = NSMutableURLRequest(URL: NSURL(string: kLoginURL)) // Here, kLogin contains the Login API.
var session = NSURLSession.sharedSession()
request.HTTPMethod = "POST"
var err: NSError?
request.HTTPBody = NSJSONSerialization.dataWithJSONObject(self.criteriaDic(), options: nil, error: &err) // This Line fills the web service with required parameters.

Here, I have made a seperate dictionary for the parameters.
var params = ["format":"json", "MobileType":"IOS","MIN":"f8d16d98ad12acdbbe1de647414495ec","UserName":emailTxtField.text,"PWD":passwordTxtField.text,"SigninVia":"SH"]as NSDictionary

You cannot delete everything with either rmdir
or del
alone:
rmdir /s /q
does not accept wildcard params. So rmdir /s /q *
will error.del /s /f /q
will delete all files, but empty subdirectories will remain.My preferred solution (as I have used in many other batch files) is:
rmdir /s /q . 2>NUL
You need to tell the Range.RemoveDuplicates method what column to use. Additionally, since you have expressed that you have a header row, you should tell the .RemoveDuplicates method that.
Sub dedupe_abcd()
Dim icol As Long
With Sheets("Sheet1") '<-set this worksheet reference properly!
icol = Application.Match("abcd", .Rows(1), 0)
With .Cells(1, 1).CurrentRegion
.RemoveDuplicates Columns:=icol, Header:=xlYes
End With
End With
End Sub
Your original code seemed to want to remove duplicates from a single column while ignoring surrounding data. That scenario is atypical and I've included the surrounding data so that the .RemoveDuplicates process does not scramble your data. Post back a comment if you truly wanted to isolate the RemoveDuplicates process to a single column.
You can use LOAD DATA INFILE command to import csv file into table.
Check this link MySQL - LOAD DATA INFILE.
LOAD DATA LOCAL INFILE 'abc.csv' INTO TABLE abc
FIELDS TERMINATED BY ','
ENCLOSED BY '"'
LINES TERMINATED BY '\r\n'
IGNORE 1 LINES
(col1, col2, col3, col4, col5...);
For MySQL 8.0 users:
Using the LOCAL
keyword hold security risks and as of MySQL 8.0 the LOCAL
capability is set to False
by default. You might see the error:
ERROR 1148: The used command is not allowed with this MySQL version
You can overwrite it by following the instructions in the docs. Beware that such overwrite does not solve the security issue but rather just an acknowledge that you are aware and willing to take the risk.
I think that without using -exec
you can simply provide /dev/null
as at least one argument in case nothing is found:
grep -rl oldstr path | xargs sed -i 's/oldstr/newstr/g' /dev/null
Declare
private static final String TIME24HOURS_PATTERN = "([01]?[0-9]|2[0-3]):[0-5][0-9]:[0-5][0-9]";
public boolean validate(final String time) {
pattern = Pattern.compile(TIME24HOURS_PATTERN);
matcher = pattern.matcher(time);
return matcher.matches();
}
This method return "true" when String match with the Regular Expression.
dataGridView1.Columns
is probably of a length less than 5. Accessing dataGridView1.Columns[4]
then will be outside the list.
Even it is not a good way of doing what you want try this hint: var url = MUST BE A NUMER FIRST
function nextImage (){
url = url + 1;
location.href='http://mywebsite.com/' + url+'.html';
}
followers_df.reset_index()
followers_df.reindex(index=range(0,20))
You can try using AppDomain.UnhandledException and see if that lets you catch it.
**EDIT*
Here is some more information that might be useful (it's a long read).
Similar to previous answers but the following solution worked for for me on windows using Python3 to provide a common method to print and log in realtime (getting-realtime-output-using-python):
def print_and_log(command, logFile):
with open(logFile, 'wb') as f:
command = subprocess.Popen(command, stdout=subprocess.PIPE, shell=True)
while True:
output = command.stdout.readline()
if not output and command.poll() is not None:
f.close()
break
if output:
f.write(output)
print(str(output.strip(), 'utf-8'), flush=True)
return command.poll()
Under the help menu, there should be a menu item labeled "About Eclipse" I can't say with absolute precision because I'm using STS which is the same thing but my label is different.
In the dialog box that opens after you click the relevant about menu item there should be an installation details button in the lower left hand corner.
The version of Java that you're running Eclipse against ought to be in "System properties:" under the "Configuration" tab.
alpha-channel is the only data of the image that Android uses for notification icons:
alpha == 1
: pixels show whitealpha == 0
: pixels show as the color you chose at Notification.Builder#setColor(int)
This is mentioned at https://developer.android.com/about/versions/android-5.0-changes.html :
The system ignores all non-alpha channels in action icons and in the main notification icon. You should assume that these icons will be alpha-only.
Almost all built-in drawables seem to be suitable alpha images for this, so you might use something like:
Notification.Builder.setColor(Color.RED)
.setSmallIcon(android.R.drawable.star_on)
but I'm still looking for the API doc that officially confirms that.
Tested on Android 22.
PowerShell has built-in XML and XPath functions. You can use the Select-Xml cmdlet with an XPath query to select nodes from XML object and then .Node.'#text' to access node value.
[xml]$xml = Get-Content $serviceStatePath
$nodes = Select-Xml "//Object[Property/@Name='ServiceState' and Property='Running']/Property[@Name='DisplayName']" $xml
$nodes | ForEach-Object {$_.Node.'#text'}
Or shorter
[xml]$xml = Get-Content $serviceStatePath
Select-Xml "//Object[Property/@Name='ServiceState' and Property='Running']/Property[@Name='DisplayName']" $xml |
% {$_.Node.'#text'}
Are they the home directories of users in /etc/passwd
? Services like postgres, sendmail, apache, etc., create system users that have home directories just like normal users.
USE A TOOLBAR
You can set a custom toolbar item color dynamically by creating a custom toolbar class:
package view;
import android.app.Activity;
import android.content.Context;
import android.graphics.ColorFilter;
import android.graphics.PorterDuff;
import android.graphics.PorterDuffColorFilter;
import android.support.v7.internal.view.menu.ActionMenuItemView;
import android.support.v7.widget.ActionMenuView;
import android.support.v7.widget.Toolbar;
import android.util.AttributeSet;
import android.util.Log;
import android.view.View;
import android.view.ViewGroup;
import android.widget.AutoCompleteTextView;
import android.widget.EditText;
import android.widget.ImageButton;
import android.widget.ImageView;
import android.widget.TextView;
public class CustomToolbar extends Toolbar{
public CustomToolbar(Context context, AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
// TODO Auto-generated constructor stub
}
public CustomToolbar(Context context, AttributeSet attrs) {
super(context, attrs);
// TODO Auto-generated constructor stub
}
public CustomToolbar(Context context) {
super(context);
// TODO Auto-generated constructor stub
ctxt = context;
}
int itemColor;
Context ctxt;
@Override
protected void onLayout(boolean changed, int l, int t, int r, int b) {
Log.d("LL", "onLayout");
super.onLayout(changed, l, t, r, b);
colorizeToolbar(this, itemColor, (Activity) ctxt);
}
public void setItemColor(int color){
itemColor = color;
colorizeToolbar(this, itemColor, (Activity) ctxt);
}
/**
* Use this method to colorize toolbar icons to the desired target color
* @param toolbarView toolbar view being colored
* @param toolbarIconsColor the target color of toolbar icons
* @param activity reference to activity needed to register observers
*/
public static void colorizeToolbar(Toolbar toolbarView, int toolbarIconsColor, Activity activity) {
final PorterDuffColorFilter colorFilter
= new PorterDuffColorFilter(toolbarIconsColor, PorterDuff.Mode.SRC_IN);
for(int i = 0; i < toolbarView.getChildCount(); i++) {
final View v = toolbarView.getChildAt(i);
doColorizing(v, colorFilter, toolbarIconsColor);
}
//Step 3: Changing the color of title and subtitle.
toolbarView.setTitleTextColor(toolbarIconsColor);
toolbarView.setSubtitleTextColor(toolbarIconsColor);
}
public static void doColorizing(View v, final ColorFilter colorFilter, int toolbarIconsColor){
if(v instanceof ImageButton) {
((ImageButton)v).getDrawable().setAlpha(255);
((ImageButton)v).getDrawable().setColorFilter(colorFilter);
}
if(v instanceof ImageView) {
((ImageView)v).getDrawable().setAlpha(255);
((ImageView)v).getDrawable().setColorFilter(colorFilter);
}
if(v instanceof AutoCompleteTextView) {
((AutoCompleteTextView)v).setTextColor(toolbarIconsColor);
}
if(v instanceof TextView) {
((TextView)v).setTextColor(toolbarIconsColor);
}
if(v instanceof EditText) {
((EditText)v).setTextColor(toolbarIconsColor);
}
if (v instanceof ViewGroup){
for (int lli =0; lli< ((ViewGroup)v).getChildCount(); lli ++){
doColorizing(((ViewGroup)v).getChildAt(lli), colorFilter, toolbarIconsColor);
}
}
if(v instanceof ActionMenuView) {
for(int j = 0; j < ((ActionMenuView)v).getChildCount(); j++) {
//Step 2: Changing the color of any ActionMenuViews - icons that
//are not back button, nor text, nor overflow menu icon.
final View innerView = ((ActionMenuView)v).getChildAt(j);
if(innerView instanceof ActionMenuItemView) {
int drawablesCount = ((ActionMenuItemView)innerView).getCompoundDrawables().length;
for(int k = 0; k < drawablesCount; k++) {
if(((ActionMenuItemView)innerView).getCompoundDrawables()[k] != null) {
final int finalK = k;
//Important to set the color filter in seperate thread,
//by adding it to the message queue
//Won't work otherwise.
//Works fine for my case but needs more testing
((ActionMenuItemView) innerView).getCompoundDrawables()[finalK].setColorFilter(colorFilter);
// innerView.post(new Runnable() {
// @Override
// public void run() {
// ((ActionMenuItemView) innerView).getCompoundDrawables()[finalK].setColorFilter(colorFilter);
// }
// });
}
}
}
}
}
}
}
then refer to it in your layout file. Now you can set a custom color using
toolbar.setItemColor(Color.Red);

I found the information to do this here: How to dynamicaly change Android Toolbar icons color
and then I edited it, improved upon it, and posted it here: GitHub:AndroidDynamicToolbarItemColor
Simply pass the desired value as first argument, like 0
, math.inf
or, here, np.nan
. The constructor then initializes and fills the value array to the size specified by arguments index
and columns
:
>>> import numpy as np
>>> import pandas as pd
>>> df = pd.DataFrame(np.nan, index=[0, 1, 2, 3], columns=['A', 'B'])
>>> df.dtypes
A float64
B float64
dtype: object
>>> df.values
array([[nan, nan],
[nan, nan],
[nan, nan],
[nan, nan]])
Yes, assuming the account has appropriate permissions you can use:
SELECT <...>
FROM A.table1 t1 JOIN B.table2 t2 ON t2.column2 = t1.column1;
You just need to prefix the table reference with the name of the database it resides in.
In Python >= 3.2 you can simply use this:
>>> from datetime import datetime, timezone
>>> datetime.now(timezone.utc).isoformat()
'2019-03-14T07:55:36.979511+00:00'
It's an excellent question, I had the same question yesterday. I thought about this problem, specifically SEARCHED if existed something like "ON UPDATE CASCADE" and fortunately the designers of SQL had also thought about that. I agree with Ted.strauss, and I also commented Noran's case.
When did I use it? Like Ted pointed out, when you are treating several databases at one time, and the modification in one of them, in one table, has any kind of reproduction in what Ted calls "satellite database", can't be kept with the very original ID, and for any reason you have to create a new one, in case you can't update the data on the old one (for example due to permissions, or in case you are searching for fastness in a case that is so ephemeral that doesn't deserve the absolute and utter respect for the total rules of normalization, simply because will be a very short-lived utility)
So, I agree in two points:
(A.) Yes, in many times a better design can avoid it; BUT
(B.) In cases of migrations, replicating databases, or solving emergencies, it's a GREAT TOOL that fortunately was there when I went to search if it existed.
If your tiles are not in your bundle, either copied from the bundle or downloaded from the internet you can get the directory like this
NSString *documentdir = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject];
NSString *tileDirectory = [documentdir stringByAppendingPathComponent:@"xxxx/Tiles"];
NSLog(@"Tile Directory: %@", tileDirectory);
1 and 2 are SAML 1.1 because those URIs were part of the OASIS SAML 1.1 standard. Section 8.3 of the linked PDF for the OASIS SAML 2.0 standard explains this:
Where possible an existing URN is used to specify a protocol. In the case of IETF protocols, the URN of the most current RFC that specifies the protocol is used. URI references created specifically for SAML have one of the following stems, according to the specification set version in which they were first introduced:
urn:oasis:names:tc:SAML:1.0: urn:oasis:names:tc:SAML:1.1: urn:oasis:names:tc:SAML:2.0:
Additional to tomaskazemekas's answer: you should install spyder in that virtual environment by:
conda install -n myenv spyder
(on Windows, for Linux or MacOS, you can search for similar commands)
If the goal is to be able to push to a GitHub repo whenever you want to, then in Windows under C:\Users\tiago\.ssh
where the keys are stored (at least in my case), create a file named config and add the following in it
Host github.com
HostName github.com
User your_user_name
IdentityFile ~/.ssh/your_file_name
Then simply open Git Bash and you'll be able to push without having to manually start the ssh-agent and adding the key.
In Rails 3, you could do
$rails new projectname --database=mysql
Look here, the operator used is !!
.
I.e. [1,2,3]!!1
gives you 2
, since lists are 0-indexed.
The example below is an adaptation and simplification of a longer post from We ? Swift. This is what it will look like:
It can be just the usual Single View Application.
Replace the ViewController.swift code with the following:
import UIKit
class ViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {
// Data model: These strings will be the data for the table view cells
let animals: [String] = ["Horse", "Cow", "Camel", "Sheep", "Goat"]
// cell reuse id (cells that scroll out of view can be reused)
let cellReuseIdentifier = "cell"
// don't forget to hook this up from the storyboard
@IBOutlet var tableView: UITableView!
override func viewDidLoad() {
super.viewDidLoad()
// Register the table view cell class and its reuse id
self.tableView.register(UITableViewCell.self, forCellReuseIdentifier: cellReuseIdentifier)
// (optional) include this line if you want to remove the extra empty cell divider lines
// self.tableView.tableFooterView = UIView()
// This view controller itself will provide the delegate methods and row data for the table view.
tableView.delegate = self
tableView.dataSource = self
}
// number of rows in table view
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return self.animals.count
}
// create a cell for each table view row
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
// create a new cell if needed or reuse an old one
let cell:UITableViewCell = self.tableView.dequeueReusableCell(withIdentifier: cellReuseIdentifier) as UITableViewCell!
// set the text from the data model
cell.textLabel?.text = self.animals[indexPath.row]
return cell
}
// method to run when table view cell is tapped
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
print("You tapped cell number \(indexPath.row).")
}
}
Read the in-code comments to see what is happening. The highlights are
UITableViewDelegate
and UITableViewDataSource
protocols.numberOfRowsInSection
method determines how many rows there will be in the table view.cellForRowAtIndexPath
method sets up each row.didSelectRowAtIndexPath
method is called every time a row is tapped.Drag a UITableView
onto your View Controller. Use auto layout to pin the four sides.
Control drag from the Table View in IB to the tableView
outlet in the code.
That's all. You should be able run your app now.
This answer was tested with Xcode 9 and Swift 4
Row Deletion
You only have to add a single method to the basic project above if you want to enable users to delete rows. See this basic example to learn how.
Row Spacing
If you would like to have spacing between your rows, see this supplemental example.
Custom cells
The default layout for the table view cells may not be what you need. Check out this example to help get you started making your own custom cells.
Dynamic Cell Height
Sometimes you don't want every cell to be the same height. Starting with iOS 8 it is easy to automatically set the height depending on the cell content. See this example for everything you need to get you started.
SSL properties are set at the JVM level via system properties. Meaning you can either set them when you run the program (java -D....) Or you can set them in code by doing System.setProperty.
The specific keys you have to set are below:
javax.net.ssl.keyStore- Location of the Java keystore file containing an application process's own certificate and private key. On Windows, the specified pathname must use forward slashes, /, in place of backslashes.
javax.net.ssl.keyStorePassword - Password to access the private key from the keystore file specified by javax.net.ssl.keyStore. This password is used twice: To unlock the keystore file (store password), and To decrypt the private key stored in the keystore (key password).
javax.net.ssl.trustStore - Location of the Java keystore file containing the collection of CA certificates trusted by this application process (trust store). On Windows, the specified pathname must use forward slashes,
/
, in place of backslashes,\
.If a trust store location is not specified using this property, the SunJSSE implementation searches for and uses a keystore file in the following locations (in order):
$JAVA_HOME/lib/security/jssecacerts
$JAVA_HOME/lib/security/cacerts
javax.net.ssl.trustStorePassword - Password to unlock the keystore file (store password) specified by
javax.net.ssl.trustStore
.javax.net.ssl.trustStoreType - (Optional) For Java keystore file format, this property has the value jks (or JKS). You do not normally specify this property, because its default value is already jks.
javax.net.debug - To switch on logging for the SSL/TLS layer, set this property to ssl.
Use
text-align: right
The text-align CSS property describes how inline content like text is aligned in its parent block element. text-align does not control the alignment of block elements itself, only their inline content.
See
<td class='alnright'>text to be aligned to right</td>
<style>
.alnright { text-align: right; }
</style>
If you're using V4.1, and according to their docs, don't assign .table-responsive directly to the table. The table should be .table and if you want it to be horizontally scrollable (responsive) add it inside a .table-responsive container (a <div>
, for instance).
Responsive tables allow tables to be scrolled horizontally with ease. Make any table responsive across all viewports by wrapping a .table with .table-responsive.
<div class="table-responsive">
<table class="table">
...
</table>
</div>
doing that, no extra css is needed.
In the OP's code, .table-responsive can be used alongside with the .col-md-12 on the outside .
If you are looking at an office setting with regular office non technical users than Sharepoint is a viable alternative. You can setup document folders with version control enabled and checkins and checkouts. Makes it freindlier for regular office users.
Given you start with mapping.get("servers").getAsJsonArray()
, if you have access to Guava Streams
, you can do the below one-liner:
List<String> servers = Streams.stream(jsonArray.iterator())
.map(je -> je.getAsString())
.collect(Collectors.toList());
Note StreamSupport
won't be able to work on JsonElement
type, so it is insufficient.

.I am using Laravel 4.2.
the error you are seeing
[Illuminate\Database\Eloquent\MassAssignmentException]
username
indeed is because the database is protected from filling en masse, which is what you are doing when you are executing a seeder. However, in my opinion, it's not necessary (and might be insecure) to declare which fields should be fillable in your model if you only need to execute a seeder.
In your seeding folder you have the DatabaseSeeder class:
class DatabaseSeeder extends Seeder {
/**
* Run the database seeds.
*
* @return void
*/
public function run()
{
Eloquent::unguard();
//$this->call('UserTableSeeder');
}
}
This class acts as a facade, listing all the seeders that need to be executed. If you call the UsersTableSeeder seeder manually through artisan, like you did with the php artisan db:seed --class="UsersTableSeeder"
command, you bypass this DatabaseSeeder class.
In this DatabaseSeeder class the command Eloquent::unguard();
allows temporary mass assignment on all tables, which is exactly what you need when you are seeding a database. This unguard method is only executed when you run the php aristan db:seed
command, hence it being temporary as opposed to making the fields fillable in your model (as stated in the accepted and other answers).
All you need to do is add the $this->call('UsersTableSeeder');
to the run method in the DatabaseSeeder class and run php aristan db:seed
in your CLI which by default will execute DatabaseSeeder.
Also note that you are using a plural classname Users, while Laraval uses the the singular form User. If you decide to change your class to the conventional singular form, you can simply uncomment the //$this->call('UserTableSeeder');
which has already been assigned but commented out by default in the DatabaseSeeder class.
This should also do the job but this is across SQL and not postgres specific.

Bit late to the party, but this will get it done. I left the example at 600, as that is what most people will use:
Similar to Shay's example except this also includes max-width to work on the rest of the clients that do have support, as well as a second method to prevent the expansion (media query) which is needed for Outlook '11.

Here is another example of this in use: Responsive order confirmation emails for mobile devices?
GET Scroll Position:
var scrolled_val = window.scrollY;
DETECT Scroll Position:
$(window).scroll
(
function (event)
{
var scrolled_val = window.scrollY;
alert(scrolled_val);
}
);
Try this
$file = basename($_SERVER['PATH_INFO']);//Filename requested
_x000D_
Another way to do this is using ":after" (pseudo-element) on the element you want to underline.
h2{
position:relative;
display:inline-block;
font-weight:700;
font-family:arial,sans-serif;
text-transform:uppercase;
font-size:3em;
}
h2:after{
content:"";
position:absolute;
left:0;
bottom:0;
right:0;
margin:auto;
background:#000;
height:1px;
}
I tried using React.FormEvent<HTMLSelectElement>
but it led to an error in the editor, even though there is no EventTarget
visible in the code:
The property 'value' does not exist on value of type 'EventTarget'
Then I changed React.FormEvent
to React.ChangeEvent
and it helped:
private changeName(event: React.ChangeEvent<HTMLSelectElement>) {
event.preventDefault();
this.props.actions.changeName(event.target.value);
}
You mention that there are date duplicates, but it appears they're quite unique down to the precision of seconds.
Can you clarify what precision of date you start considering dates duplicate - day, hour, minute?
In any case, you'll probably want to floor your datetime field. You didn't indicate which field is preferred when removing duplicates, so this query will prefer the last name in alphabetical order.
SELECT MAX(owner_name),
--floored to the second
dateadd(second,datediff(second,'2000-01-01',start_date),'2000-01-01') AS StartDate
From MyTable
GROUP BY dateadd(second,datediff(second,'2000-01-01',start_date),'2000-01-01')
ALTER TABLE Employee ADD DEFAULT 'SANDNES' FOR CityBorn
in case it helps someone, on amilinux, with php5.6 and php-fpm installed, it's:
sudo /etc/init.d/php-fpm-5.6 status
Found this on a different forum
If you're wondering why that leading zero is important, it's because permissions are set as an octal integer, and Python automagically treats any integer with a leading zero as octal. So os.chmod("file", 484) (in decimal) would give the same result.
What you are doing is passing 664
which in octal is 1230
In your case you would need
os.chmod("/tmp/test_file", 436)
[Update] Note, for Python 3 you have prefix with 0o (zero oh). E.G, 0o666
There are two more solutions:
Create:
du -csxb /path | md5sum > file
ls -alR -I dev -I run -I sys -I tmp -I proc /path | md5sum > /tmp/file
Check:
du -csxb /path | md5sum -c file
ls -alR -I dev -I run -I sys -I tmp -I proc /path | md5sum -c /tmp/file
Incase anyone happens to land here (like I did) looking to add a CA (in my case Charles Proxy) for httplib2, it looks like you can append it to the cacerts.txt
file included with the python package.
For example:
cat ~/Desktop/charles-ssl-proxying-certificate.pem >> /usr/local/google-cloud-sdk/lib/third_party/httplib2/cacerts.txt
The environment variables referenced in other solutions appear to be requests-specific and were not picked up by httplib2 in my testing.
You would need to do something like this. I am typing this off the top of my head, so this may not be 100% correct.
CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceRGB(); CGContextRef context = CGBitmapContextCreate(NULL, 640, 360, 8, 4 * width, colorSpace, kCGImageAlphaPremultipliedFirst); CGColorSpaceRelease(colorSpace); CGContextDrawImage(context, CGRectMake(0,-160,640,360), cgImgFromAVCaptureSession); CGImageRef image = CGBitmapContextCreateImage(context); UIImage* myCroppedImg = [UIImage imageWithCGImage:image]; CGContextRelease(context);
