You might have problem on Windows while adding jar to maven because of syntax.
Try encapsulating -D parameters with double quotas like this;
mvn install:install-file "-Dfile=ojdbc6.jar" "-DgroupId=com.oracle" "-DartifactId=ojdbc6" "-Dversion=11.2.0" "-Dpackaging=jar"
Be aware of you should use same version/atifactId/groupId inside your pom.xml. You can't use version 11.2.0.3 after command above. You have to put his in you pom.xml;
<dependency>
<groupId>com.oracle</groupId>
<artifactId>ojdbc6</artifactId>
<version>11.2.0</version>
</dependency>
If you want to use another version, like 12.1.0.1, you should run above command with that version or other info
Because both a
and b
have only one axis, as their shape is (3)
, and the axis parameter specifically refers to the axis of the elements to concatenate.
this example should clarify what concatenate
is doing with axis. Take two vectors with two axis, with shape (2,3)
:
a = np.array([[1,5,9], [2,6,10]])
b = np.array([[3,7,11], [4,8,12]])
concatenates along the 1st axis (rows of the 1st, then rows of the 2nd):
np.concatenate((a,b), axis=0)
array([[ 1, 5, 9],
[ 2, 6, 10],
[ 3, 7, 11],
[ 4, 8, 12]])
concatenates along the 2nd axis (columns of the 1st, then columns of the 2nd):
np.concatenate((a, b), axis=1)
array([[ 1, 5, 9, 3, 7, 11],
[ 2, 6, 10, 4, 8, 12]])
to obtain the output you presented, you can use vstack
a = np.array([1,2,3])
b = np.array([4,5,6])
np.vstack((a, b))
array([[1, 2, 3],
[4, 5, 6]])
You can still do it with concatenate
, but you need to reshape them first:
np.concatenate((a.reshape(1,3), b.reshape(1,3)))
array([[1, 2, 3],
[4, 5, 6]])
Finally, as proposed in the comments, one way to reshape them is to use newaxis
:
np.concatenate((a[np.newaxis,:], b[np.newaxis,:]))
If you can have your quote delimiter be double quotes, then this is a duplicate of Example JavaScript code to parse CSV data.
You can either translate all single-quotes to double-quotes first:
string = string.replace( /'/g, '"' );
...or you can edit the regex in that question to recognize single-quotes instead of double-quotes:
// Quoted fields.
"(?:'([^']*(?:''[^']*)*)'|" +
However, this assumes certain markup that is not clear from your question. Please clarify what all the various possibilities of markup can be, per my comment on your question.
<?
ob_start(); // ensures anything dumped out will be caught
// do stuff here
$url = 'http://example.com/thankyou.php'; // this can be set based on whatever
// clear out the output buffer
while (ob_get_status())
{
ob_end_clean();
}
// no redirect
header( "Location: $url" );
?>

We can hide close button on form by setting this.ControlBox=false;
Note that this hides all of those sizing buttons. Not just the X. In some cases that may be fine.
Try download the zip files from http://www.nltk.org/nltk_data/ and then unzip, save in your Python folder, such as C:\ProgramData\Anaconda3\nltk_data
remember, SSL/TLS operates at the Transport Layer, so all the crypto goo happens under the application-layer HTTP stuff.
http://en.wikipedia.org/wiki/File:IP_stack_connections.svg
that's the long way of saying, "Yes!"
Python uses duck typing, so it doesn't need special syntax to handle multiple types.
If you're from a C++ background, you'll remember that, as long as the operations used in the template function/class are defined on some type T
(at the syntax level), you can use that type T
in the template.
So, basically, it works the same way:
You'll note however, that unless you write explicit type checking (which is usually discouraged), you won't be able to enforce that a binary tree contains only elements of the chosen type.
A better solution without if-else:
$(document).ready(function() {
$("#chkdwn2").click(function() {
$("#dropdown").prop("disabled", this.checked);
});
});
Here is a simple couple lines that looks for extention as well as provides a sort option
def get_sorted_files(src_dir, regex_ext='*', sort_reverse=False):
files_to_evaluate = [os.path.join(src_dir, f) for f in os.listdir(src_dir) if re.search(r'.*\.({})$'.format(regex_ext), f)]
files_to_evaluate.sort(key=os.path.getmtime, reverse=sort_reverse)
return files_to_evaluate
There's nothing in the BCL to do this for you, but there are two great libraries for .NET which do support the functionality.
I've used both and can say that the two are very complete and have well-designed APIs, so it's mainly a matter of personal preference.
I'm not sure whether they explicitly support adding Folders rather than just individual files to zip files, but it should be quite easy to create something that recursively iterated over a directory and its sub-directories using the DirectoryInfo
and FileInfo
classes.
The path you give to LOAD DATA INFILE
is for the filesystem on the machine where the server is running, not the machine you connect from. LOAD DATA LOCAL INFILE
is for the client's machine, but it requires that the server was started with the right settings, otherwise it's not allowed. You can read all about it here: http://dev.mysql.com/doc/refman/5.0/en/load-data-local.html
As for SELECT INTO OUTFILE
I'm not sure why there is not a local version, besides it probably being tricky to do over the connection. You can get the same functionality through the mysqldump
tool, but not through sending SQL to the server.
I have lost hours today to find the reason, fortunately this issue is not because of MapFragment implementation, fnfortunately, this does not work because nested fragments are only supported through support library from rev 11.
My implementation has an activity with actionbar (in tabbed mode) with two tabs (no viewpager), one having the map and the other having a list of entries. Of course I've been quite naive to use MapFragment inside my tab-fragments, et voila the app crashed everytime I switched back to map-tab.
( The same issue I also would have in case my tab-fragment would inflate any layout containing any other fragment ).
One option is to use the MapView (instead of MapFragment), with some overhead though ( see MapView Docs as drop-in replacement in the layout.xml, another option is to use support-library up from rev. 11 but then take programmatic approach since nested fragments are neither supported via layout. Or just working around programmatically by explicitely destroying the fragment (like in the answer from Matt / Vidar), btw: same effect is achieved using the MapView (option 1).
But actually, I did not want to loose the map everytime I tab away, that is, I wanted to keep it in memory and cleanup only upon activity close, so I decided to simply hide/show the map while tabbing, see FragmentTransaction / hide
This is an example of using REG_EXTENDED. This regular expression
"^(-)?([0-9]+)((,|.)([0-9]+))?\n$"
Allows you to catch decimal numbers in Spanish system and international. :)
#include <regex.h>
#include <stdlib.h>
#include <stdio.h>
regex_t regex;
int reti;
char msgbuf[100];
int main(int argc, char const *argv[])
{
while(1){
fgets( msgbuf, 100, stdin );
reti = regcomp(®ex, "^(-)?([0-9]+)((,|.)([0-9]+))?\n$", REG_EXTENDED);
if (reti) {
fprintf(stderr, "Could not compile regex\n");
exit(1);
}
/* Execute regular expression */
printf("%s\n", msgbuf);
reti = regexec(®ex, msgbuf, 0, NULL, 0);
if (!reti) {
puts("Match");
}
else if (reti == REG_NOMATCH) {
puts("No match");
}
else {
regerror(reti, ®ex, msgbuf, sizeof(msgbuf));
fprintf(stderr, "Regex match failed: %s\n", msgbuf);
exit(1);
}
/* Free memory allocated to the pattern buffer by regcomp() */
regfree(®ex);
}
}
Inline tag is used to add another src of document to the current html element.
In your case an video of a youtube and we need to specify the html type(4 or 5) to the browser externally to the link
so add ?html=5 to the end of the link.. :)
If are using jQuery, grep may be useful:
var arr = [ a, b, c, , e, f, , g, h ];
arr = jQuery.grep(arr, function(n){ return (n); });
arr
is now [ a, b, c, d, e, f, g];
Use TO_TIMESTAMP function
TO_TIMESTAMP(date_string,'YYYY-MM-DD HH24:MI:SS')
Replace
#include "Landing.h"
with
class Landing;
If you still get errors, also post Item.h
, Flight.h
and common.h
EDIT: In response to comment.
You will need to e.g. #include "Landing.h"
from Event.cpp
in order to actually use the class. You just cannot include it from Event.h
To get the version numbers try
System.Reflection.Assembly assembly = System.Reflection.Assembly.GetExecutingAssembly();
System.Reflection.AssemblyName assemblyName = assembly.GetName();
Version version = assemblyName.Version;
To set the version number, create/edit AssemblyInfo.cs
[assembly: AssemblyVersion("1.0.*")]
[assembly: AssemblyFileVersion("1.0.*")]
Also as a side note, the third number is the number of days since 2/1/2000 and the fourth number is half of the amount of total seconds in the day. So if you compile at midnight it should be zero.
alternatively you can set remote to http by using this command in the existing repo, and use this command git remote set-url origin https://gitlab.com/[username]/[repo-name].git
First of all, stop using impossible-to-understand class names like A, B, C. Use Animal, Mammal, Giraffe, or Food, Fruit, Orange or something where the relationships are clear.
Your question then is "why can I not assign a list of giraffes to a variable of type list of animal, since I can assign a giraffe to a variable of type animal?"
The answer is: suppose you could. What could then go wrong?
Well, you can add a Tiger to a list of animals. Suppose we allow you to put a list of giraffes in a variable that holds a list of animals. Then you try to add a tiger to that list. What happens? Do you want the list of giraffes to contain a tiger? Do you want a crash? or do you want the compiler to protect you from the crash by making the assignment illegal in the first place?
We choose the latter.
This kind of conversion is called a "covariant" conversion. In C# 4 we will allow you to make covariant conversions on interfaces and delegates when the conversion is known to be always safe. See my blog articles on covariance and contravariance for details. (There will be a fresh one on this topic on both Monday and Thursday of this week.)
A few things you could use:
dir()
will give you the list of in scope variables:globals()
will give you a dictionary of global variableslocals()
will give you a dictionary of local variablesWe are already in 21st century!! Don't try to implement the already existing data structures. Try to use the existing data structures.
Use STL or Boost library
Run these commands for Beyond Compare 3(if the BCompare.exe path is different in your system, please replace it according to yours):
git config --global diff.tool bc3
git config --global difftool.bc3.cmd "\"c:/program files (x86)/beyond compare 3/BCompare.exe\" \"$LOCAL\" \"$REMOTE\""
git config --global difftool.prompt false
Then use git difftool
Just make round(x-0.5) this will always return the next rounded down Integer value of your Float. You can also easily round up by do round(x+0.5)
Try adding scrolling="no"

Regular expression for matching everything after "net" and before ".php":
$pattern = "net([a-zA-Z0-9_]*)\.php";
In the above regular expression, you can find the matching group of characters enclosed by "()" to be what you are looking for.
Hope it's useful.
Using @property
and @dynamic
could also work. If you declare a dynamic property and don't give a matching method implementation, everything will still compile without warnings, and you'll get an unrecognized selector
error at runtime if you try to access it. This essentially the same thing as calling [self doesNotRecognizeSelector:_cmd]
, but with far less typing.

Running as admin didn't help me. (also got errors with syscall: rename)
Turns out this error can also occur if files are locked by Windows.
This can occur if :
Running as admin doesn't get around windows file locking.
I created a new project in VS2017 and then switched to VSCode to try to add more packages. After stopping the project from running and closing VS2017 it was able to complete without error
Disclaimer: I'm not exactly sure if this means running as admin isn't necessary, but try to avoid it if possible to avoid the possibility of some rogue package doing stuff it isn't meant to.
Aggregate used to sum columns in a multi dimensional integer array
int[][] nonMagicSquare =
{
new int[] { 3, 1, 7, 8 },
new int[] { 2, 4, 16, 5 },
new int[] { 11, 6, 12, 15 },
new int[] { 9, 13, 10, 14 }
};
IEnumerable<int> rowSums = nonMagicSquare
.Select(row => row.Sum());
IEnumerable<int> colSums = nonMagicSquare
.Aggregate(
(priorSums, currentRow) =>
priorSums.Select((priorSum, index) => priorSum + currentRow[index]).ToArray()
);
Select with index is used within the Aggregate func to sum the matching columns and return a new Array; { 3 + 2 = 5, 1 + 4 = 5, 7 + 16 = 23, 8 + 5 = 13 }.
Console.WriteLine("rowSums: " + string.Join(", ", rowSums)); // rowSums: 19, 27, 44, 46
Console.WriteLine("colSums: " + string.Join(", ", colSums)); // colSums: 25, 24, 45, 42
But counting the number of trues in a Boolean array is more difficult since the accumulated type (int) differs from the source type (bool); here a seed is necessary in order to use the second overload.
bool[][] booleanTable =
{
new bool[] { true, true, true, false },
new bool[] { false, false, false, true },
new bool[] { true, false, false, true },
new bool[] { true, true, false, false }
};
IEnumerable<int> rowCounts = booleanTable
.Select(row => row.Select(value => value ? 1 : 0).Sum());
IEnumerable<int> seed = new int[booleanTable.First().Length];
IEnumerable<int> colCounts = booleanTable
.Aggregate(seed,
(priorSums, currentRow) =>
priorSums.Select((priorSum, index) => priorSum + (currentRow[index] ? 1 : 0)).ToArray()
);
Console.WriteLine("rowCounts: " + string.Join(", ", rowCounts)); // rowCounts: 3, 1, 2, 2
Console.WriteLine("colCounts: " + string.Join(", ", colCounts)); // colCounts: 3, 2, 1, 2
You can also do this:
NSNumber *number = @([dictionary[@"id"] intValue]]);
Have fun!
So long as your text-editors can cope with Unicode (presumably encoded in UTF-8) you can enter the Unicode code-point directly.
For instance, in the Vim text-editor you would enter insert mode and press Ctrl + V + U and then the code-point number as a 4-digit hexadecimal number (pad with zeros if necessary). So you would type Ctrl + V + U 2 6 2 0. See: What is the easiest way to insert Unicode characters into a document?
At a terminal running Bash you would type CTRL+SHIFT+U and type in the hexadecimal code-point of the character you want. During input your cursor should show an underlined u
. The first non-digit you type ends input, and renders the character. So you could be able to print U+2620 in Bash using the following:
echo CTRL+SHIFT+U2620ENTERENTER
(The first enter ends Unicode input, and the second runs the echo
command.)

You need to wrap them all in a character class. The current version means replace this sequence of characters with an empty string. When wrapped in square brackets it means replace any of these characters with an empty string.
var cleanString = dirtyString.replace(/[\|&;\$%@"<>\(\)\+,]/g, "");
Knowing the version of Windows and SQL Server might be helpful in some cases. From the Native Client 10.0 I infer either SQL Server 2008 or SQL Server 2008 R2.
There are a few possible things to check, but I would check to see if 'priority boost' was configured on the SQL Server. This is a deprecated setting and will eventually be removed. The problem is that it can rob the operating system of needed resources. See the notes at:
http://msdn.microsoft.com/en-in/library/ms180943(v=SQL.105).aspx
If 'priority boost' has been configured to 1, then get it configured back to 0.
exec sp_configure 'priority boost', 0;
RECONFIGURE;
Code and explanation from Pointer Basics:
The dereference operation starts at the pointer and follows its arrow over to access its pointee. The goal may be to look at the pointee state or to change the pointee state. The dereference operation on a pointer only works if the pointer has a pointee -- the pointee must be allocated and the pointer must be set to point to it. The most common error in pointer code is forgetting to set up the pointee. The most common runtime crash because of that error in the code is a failed dereference operation. In Java the incorrect dereference will be flagged politely by the runtime system. In compiled languages such as C, C++, and Pascal, the incorrect dereference will sometimes crash, and other times corrupt memory in some subtle, random way. Pointer bugs in compiled languages can be difficult to track down for this reason.
void main() {
int* x; // Allocate the pointer x
x = malloc(sizeof(int)); // Allocate an int pointee,
// and set x to point to it
*x = 42; // Dereference x to store 42 in its pointee
}
For those attempting Richard's solution above, here are some additional information that might help navigate common errors:
1) When running restore filelistonly you may get Operating system error 5(Access is denied). If that's the case, open SQL Server Configuration Manager and change the login for SQLEXPRESS to a user that has local write privileges.
2) @"This will list the contents of the backup - what you need is the first fields that tell you the logical names" - if your file lists more than two headers you will need to also account for what to do with those files in the RESTORE DATABASE command. If you don't indicate what to do with files beyond the database and the log, the system will apparently try to use the attributes listed in the .bak file. Restoring a file from someone else's environment will produce a 'The path has invalid attributes. It needs to be a directory' (as the path in question doesn't exist on your machine). Simply providing a MOVE statement resolves this problem.
In my case there was a third FTData type file. The MOVE command I added:
MOVE 'mydbName_log' TO 'c:\temp\mydbName_data.ldf',
MOVE 'sysft_...' TO 'c:\temp\other';
in my case I actually had to make a new directory for the third file. Initially I tried to send it to the same folder as the .mdf file but that produced a 'failed to initialize correctly' error on the third FTData file when I executed the restore.
If you are working with Android's MediaStore database, here is how to store an image and then display it after it is saved.
on button click write this
Intent in = new Intent(Intent.ACTION_PICK,
android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
in.putExtra("crop", "true");
in.putExtra("outputX", 100);
in.putExtra("outputY", 100);
in.putExtra("scale", true);
in.putExtra("return-data", true);
startActivityForResult(in, 1);
then do this in your activity
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
// TODO Auto-generated method stub
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == 1 && resultCode == RESULT_OK && data != null) {
Bitmap bmp = (Bitmap) data.getExtras().get("data");
img.setImageBitmap(bmp);
btnadd.requestFocus();
ByteArrayOutputStream baos = new ByteArrayOutputStream();
bmp.compress(Bitmap.CompressFormat.JPEG, 100, baos);
byte[] b = baos.toByteArray();
String encodedImageString = Base64.encodeToString(b, Base64.DEFAULT);
byte[] bytarray = Base64.decode(encodedImageString, Base64.DEFAULT);
Bitmap bmimage = BitmapFactory.decodeByteArray(bytarray, 0,
bytarray.length);
}
}
public IList<Splitting> get(Guid companyId, long customrId) {
var res=from c in Customers_data_source
where c.CustomerId = customrId && c.CompanyID == companyId
from s in Splittings_data_srouce
where s.CustomerID = c.CustomerID
select s;
return res.ToList();
}
Trim()
will only remove leading or trailing spaces.
Try .Contains()
to check if a string contains white space
"sossjjs sskkk".Contains(" ") // returns true
You are probably storing the value 0xc0 in a char
variable, what is probably a signed type, and your value is negative (most significant bit set). Then, when printing, it is converted to int
, and to keep the semantical equivalence, the compiler pads the extra bytes with 0xff, so the negative int
will have the same numerical value of your negative char
. To fix this, just cast to unsigned char
when printing:
printf("%x", (unsigned char)variable);

void MainWindow::openNewWindow()
{
mMyNewWindow = new NewWindow(); // Be sure to destroy your window somewhere
mMyNewWindow->show();
// ...
}
This is an example on how display a custom new window. There are a lot of ways to do this.

var select = $("#productSelect")
for (var prop in data) {
var option = document.createElement('option');
option.innerHTML = data[prop].ProduktName
option.value = data[prop].ProduktName;
select.append(option)
}
The reason why im posting this is because appendChild() wasn´t working in my case so I decided to put up another possibility that works aswell.
If you want to use for <input>
it will not work, for <input>
or text area you need to use Javascript
<script language="javascript" type="text/javascript">
function capitaliseName()
{
var str = document.getElementById("name").value;
document.getElementById("name").value = str.charAt(0).toUpperCase() + str.slice(1);
}
</script>
<textarea name="NAME" id="name" onkeydown = "capitaliseName()"></textarea>
that is supposed to work well for <input>
or <textarea>
Plotly supports interactive 2D and 3D graphing. Graphs are rendered with D3.js and can be created with a Python API, matplotlib, ggplot for Python, Seaborn, prettyplotlib, and pandas. You can zoom, pan, toggle traces on and off, and see data on the hover. Plots can be embedded in HTML, apps, dashboards, and IPython Notebooks. Below is a temperature graph showing interactivity. See the gallery of IPython Notebooks tutorials for more examples.
The docs provides examples of supported plot types and code snippets.
Specifically to your question, you can also make interactive plots from NetworkX.
For 3D plotting with Python, you can make 3D scatter, line, and surface plots that are similarly interactive. Plots are rendered with WebGL. For example, see a 3D graph of UK Swap rates.
Disclosure: I'm on the Plotly team.
os.path.isfile("bob.txt") # Does bob.txt exist? Is it a file, or a directory?

"hello _there_".replace(/_(.*?)_/, function(a, b){

})
Oh, or you could also:
"hello _there_".replace(/_(.*?)_/, "<div>$1</div>")

If you're using Bootstrap 4, use .w-auto
.
We can use params
, new feature of the UI-Router:
API Reference / ui.router.state / $stateProvider
params
A map which optionally configures parameters declared in the url, or defines additional non-url parameters. For each parameter being configured, add a configuration object keyed to the name of the parameter.
See the part: "...or defines additional non-url parameters..."
So the state def would be:
$stateProvider
.state('home', {
url: "/home",
templateUrl: 'tpl.html',
params: { hiddenOne: null, }
})
Few examples form the doc mentioned above:
// define a parameter's default value
params: {
param1: { value: "defaultValue" }
}
// shorthand default values
params: {
param1: "defaultValue",
param2: "param2Default"
}
// param will be array []
params: {
param1: { array: true }
}
// handling the default value in url:
params: {
param1: {
value: "defaultId",
squash: true
} }
// squash "defaultValue" to "~"
params: {
param1: {
value: "defaultValue",
squash: "~"
} }
EXTEND - working example: http://plnkr.co/edit/inFhDmP42AQyeUBmyIVl?p=info
Here is an example of a state definition:
$stateProvider
.state('home', {
url: "/home",
params : { veryLongParamHome: null, },
...
})
.state('parent', {
url: "/parent",
params : { veryLongParamParent: null, },
...
})
.state('parent.child', {
url: "/child",
params : { veryLongParamChild: null, },
...
})
This could be a call using ui-sref:
<a ui-sref="home({veryLongParamHome:'Home--f8d218ae-d998-4aa4-94ee-f27144a21238'
})">home</a>
<a ui-sref="parent({
veryLongParamParent:'Parent--2852f22c-dc85-41af-9064-d365bc4fc822'
})">parent</a>
<a ui-sref="parent.child({
veryLongParamParent:'Parent--0b2a585f-fcef-4462-b656-544e4575fca5',
veryLongParamChild:'Child--f8d218ae-d998-4aa4-94ee-f27144a61238'
})">parent.child</a>

I used preg_match to do it.
In my case, I had a string containing exactly one <img>
tag (and no other markup) that I got from Wordpress and I was trying to get the src
attribute so I could run it through timthumb.
// get the featured image
$image = get_the_post_thumbnail($photos[$i]->ID);
// get the src for that image
$pattern = '/src="([^"]*)"/';
preg_match($pattern, $image, $matches);
$src = $matches[1];
unset($matches);
In the pattern to grab the title or the alt, you could simply use $pattern = '/title="([^"]*)"/';
to grab the title or $pattern = '/title="([^"]*)"/';
to grab the alt. Sadly, my regex isn't good enough to grab all three (alt/title/src) with one pass though.
A ClassCastException
ocurrs when you try to cast an instance of an Object to a type that it is not. Casting only works when the casted object follows an "is a" relationship to the type you are trying to cast to. For Example
Apple myApple = new Apple();
Fruit myFruit = (Fruit)myApple;
This works because an apple 'is a' fruit. However if we reverse this.
Fruit myFruit = new Fruit();
Apple myApple = (Apple)myFruit;
This will throw a ClasCastException because a Fruit is not (always) an Apple.
It is good practice to guard any explicit casts with an instanceof
check first:
if (myApple instanceof Fruit) {
Fruit myFruit = (Fruit)myApple;
}
I also had the same error. In my case reason was I have created a update trigger on a table and under that trigger I am again updating the same table. And when I have removed the update statement from the trigger my problem has been resolved.
If you're using zsh, you can use multiple redirections, so you don't even need tee
:
./cmd 1>&1 2>&2 1>out_file 2>err_file
Here you're simply redirecting each stream to itself and the target file.
Full example
% (echo "out"; echo "err">/dev/stderr) 1>&1 2>&2 1>/tmp/out_file 2>/tmp/err_file
out
err
% cat /tmp/out_file
out
% cat /tmp/err_file
err
Note that this requires the MULTIOS
option to be set (which is the default).
MULTIOS
Perform implicit
tee
s orcat
s when multiple redirections are attempted (see Redirection).
Comments on EntryPoint function in code
// ENTRYPOINT /usr/sbin/nginx.
// Set the entrypoint (which defaults to sh -c) to /usr/sbin/nginx.
// Will accept the CMD as the arguments to /usr/sbin/nginx.
Another reference from documents
You can use the exec form of ENTRYPOINT to set fairly stable default commands and arguments and then use CMD to set additional defaults that are more likely to be changed.
Example:
FROM ubuntu:14.04.3
ENTRYPOINT ["/bin/ping"]
CMD ["localhost", "-c", "2"]
Build: sudo docker build -t ent_cmd .
CMD arguments are easy to override.
NO argument (sudo docker -it ent_cmd) : ping localhost
argument (sudo docker run -it ent_cmd google.com) : ping google.com
.
To override EntryPoint argument, you need to supply entrypoint
sudo docker run -it --entrypoint="/bin/bash" ent_cmdd
p.s: In presence of EntryPoint, CMD will hold arguments to fed to EntryPoint. In absense of EntryPoint, CMD will be the command which will be run.

You can't define an object literal with a dynamic key. Do this :

In addition to the other answers, the fmod
documentation has some interesting things to say on the subject:
math.fmod(x, y)
Return
fmod(x, y)
, as defined by the platform C library. Note that the Python expressionx % y
may not return the same result. The intent of the C standard is thatfmod(x, y)
be exactly (mathematically; to infinite precision) equal tox - n*y
for some integer n such that the result has the same sign asx
and magnitude less thanabs(y)
. Python’sx % y
returns a result with the sign ofy
instead, and may not be exactly computable for float arguments. For example,fmod(-1e-100, 1e100)
is-1e-100
, but the result of Python’s-1e-100 % 1e100
is1e100-1e-100
, which cannot be represented exactly as a float, and rounds to the surprising1e100
. For this reason, functionfmod()
is generally preferred when working with floats, while Python’sx % y
is preferred when working with integers.
I had same problem in the render() method. The problem comes when you return from render() as :
render() {
return
(
<div>Here comes JSX !</div>
);
}
i.e. if you start the parenthesis in a new line
Try using:
render() {
return (
<div>Here comes JSX !</div>
);
}
This will solve the error

Are you using Forms authentication?
Forms authentication uses it own value for timeout (30 min. by default). A forms authentication timeout will send the user to the login page with the session still active. This may look like the behavior your app gives when session times out making it easy to confuse one with the other.
<system.web>
<authentication mode="Forms">
<forms timeout="50"/>
</authentication>
<sessionState timeout="60" />
</system.web>
Setting the forms timeout to something less than the session timeout can give the user a window in which to log back in without losing any session data.
With argc
(argument count) and argv
(argument vector) you can get the number and the values of passed arguments when your application has been launched.
This way you can use parameters (such as -version
) when your application is started to act a different way.
But you can also use int main(void)
as a prototype in C.
There is a third (less known and nonstandard) prototype with a third argument which is envp
. It contains environment variables.

Take a look in .git/config and make the changes you need.
Alternatively you could use
git remote rm [name of the url you sets on adding]
and
git remote add [name] [URL]
Or just
git remote set-url [URL]

If you use Sqlite's REGEXP support ( see the answer at Problem with regexp python and sqlite for how to do that ) , then you can do it easily in one clause:
SELECT word FROM table WHERE word NOT REGEXP '[abc]';
As others said, if means nothing as of C++14, so let's consider the __restrict__
GCC extension which does the same as the C99 restrict
.
C99
restrict
says that two pointers cannot point to overlapping memory regions. The most common usage is for function arguments.
This restricts how the function can be called, but allows for more compile optimizations.
If the caller does not follow the restrict
contract, undefined behavior.
The C99 N1256 draft 6.7.3/7 "Type qualifiers" says:
The intended use of the restrict qualifier (like the register storage class) is to promote optimization, and deleting all instances of the qualifier from all preprocessing translation units composing a conforming program does not change its meaning (i.e., observable behavior).
and 6.7.3.1 "Formal definition of restrict" gives the gory details.
A possible optimization
The Wikipedia example is very illuminating.
It clearly shows how as it allows to save one assembly instruction.
Without restrict:
void f(int *a, int *b, int *x) {
*a += *x;
*b += *x;
}
Pseudo assembly:
load R1 ? *x ; Load the value of x pointer
load R2 ? *a ; Load the value of a pointer
add R2 += R1 ; Perform Addition
set R2 ? *a ; Update the value of a pointer
; Similarly for b, note that x is loaded twice,
; because x may point to a (a aliased by x) thus
; the value of x will change when the value of a
; changes.
load R1 ? *x
load R2 ? *b
add R2 += R1
set R2 ? *b
With restrict:
void fr(int *restrict a, int *restrict b, int *restrict x);
Pseudo assembly:
load R1 ? *x
load R2 ? *a
add R2 += R1
set R2 ? *a
; Note that x is not reloaded,
; because the compiler knows it is unchanged
; "load R1 ? *x" is no longer needed.
load R2 ? *b
add R2 += R1
set R2 ? *b
Does GCC really do it?
g++
4.8 Linux x86-64:
g++ -g -std=gnu++98 -O0 -c main.cpp
objdump -S main.o
With -O0
, they are the same.
With -O3
:
void f(int *a, int *b, int *x) {
*a += *x;
0: 8b 02 mov (%rdx),%eax
2: 01 07 add %eax,(%rdi)
*b += *x;
4: 8b 02 mov (%rdx),%eax
6: 01 06 add %eax,(%rsi)
void fr(int *__restrict__ a, int *__restrict__ b, int *__restrict__ x) {
*a += *x;
10: 8b 02 mov (%rdx),%eax
12: 01 07 add %eax,(%rdi)
*b += *x;
14: 01 06 add %eax,(%rsi)
For the uninitiated, the calling convention is:
rdi
= first parameterrsi
= second parameterrdx
= third parameterGCC output was even clearer than the wiki article: 4 instructions vs 3 instructions.
Arrays
So far we have single instruction savings, but if pointer represent arrays to be looped over, a common use case, then a bunch of instructions could be saved, as mentioned by supercat and michael.
Consider for example:
void f(char *restrict p1, char *restrict p2, size_t size) {
for (size_t i = 0; i < size; i++) {
p1[i] = 4;
p2[i] = 9;
}
}
Because of restrict
, a smart compiler (or human), could optimize that to:
memset(p1, 4, size);
memset(p2, 9, size);
Which is potentially much more efficient as it may be assembly optimized on a decent libc implementation (like glibc) Is it better to use std::memcpy() or std::copy() in terms to performance?, possibly with SIMD instructions.
Without, restrict, this optimization could not be done, e.g. consider:
char p1[4];
char *p2 = &p1[1];
f(p1, p2, 3);
Then for
version makes:
p1 == {4, 4, 4, 9}
while the memset
version makes:
p1 == {4, 9, 9, 9}
Does GCC really do it?
GCC 5.2.1.Linux x86-64 Ubuntu 15.10:
gcc -g -std=c99 -O0 -c main.c
objdump -dr main.o
With -O0
, both are the same.
With -O3
:
with restrict:
3f0: 48 85 d2 test %rdx,%rdx
3f3: 74 33 je 428 <fr+0x38>
3f5: 55 push %rbp

421: 0f 1f 80 00 00 00 00 nopl 0x0(%rax)
428: f3 c3 repz retq
Two memset
calls as expected.
without restrict: no stdlib calls, just a 16 iteration wide loop unrolling which I do not intend to reproduce here :-)
I haven't had the patience to benchmark them, but I believe that the restrict version will be faster.
Strict aliasing rule
The restrict
keyword only affects pointers of compatible types (e.g. two int*
) because the strict aliasing rules says that aliasing incompatible types is undefined behavior by default, and so compilers can assume it does not happen and optimize away.
See: What is the strict aliasing rule?
Does it work for references?
According to the GCC docs it does: https://gcc.gnu.org/onlinedocs/gcc-5.1.0/gcc/Restricted-Pointers.html with syntax:
int &__restrict__ rref
There is even a version for this
of member functions:
void T::fn () __restrict__

A convinient way is using the package python-dotenv
:
It reads out a .flaskenv
file where you can store environment variables for flask.
pip install python-dotenv
.flaskenv
in the root directory of your appInside the file you specify:
FLASK_APP=application.py
FLASK_RUN_HOST=localhost
FLASK_RUN_PORT=80
After that you just have to run your app with flask run
and can access your app at that port.
Please note that FLASK_RUN_HOST
defaults to 127.0.0.1
and FLASK_RUN_PORT
defaults to 5000

Inline functions are faster because you don't need to push and pop things on/off the stack like parameters and the return address; however, it does make your binary slightly larger.
Does it make a significant difference? Not noticeably enough on modern hardware for most. But it can make a difference, which is enough for some people.
Marking something inline does not give you a guarantee that it will be inline. It's just a suggestion to the compiler. Sometimes it's not possible such as when you have a virtual function, or when there is recursion involved. And sometimes the compiler just chooses not to use it.
I could see a situation like this making a detectable difference:
inline int aplusb_pow2(int a, int b) {
return (a + b)*(a + b) ;
}
for(int a = 0; a < 900000; ++a)
for(int b = 0; b < 900000; ++b)
aplusb_pow2(a, b);
You could just use VideoLAN. VideoLAN will work as a server (or you can wrap your own C# application around it for more control). There are also .NET wrappers for the viewer that you can use and thus embed in your C# client.

I had this same issue where I wanted to initialize my MySQL Docker instance's schema, but I ran into difficulty getting this working after doing some Googling and following others' examples. Here's how I solved it.
1) Dump your MySQL schema to a file.
mysqldump -h <your_mysql_host> -u <user_name> -p --no-data <schema_name> > schema.sql
2) Use the ADD command to add your schema file to the /docker-entrypoint-initdb.d
directory in the Docker container. The docker-entrypoint.sh
file will run any files in this directory ending with ".sql"
against the MySQL database.
Dockerfile:
FROM mysql:5.7.15
MAINTAINER me
ENV MYSQL_DATABASE=<schema_name> \
MYSQL_ROOT_PASSWORD=<password>
ADD schema.sql /docker-entrypoint-initdb.d
EXPOSE 3306
3) Start up the Docker MySQL instance.
docker-compose build
docker-compose up
Thanks to Setting up MySQL and importing dump within Dockerfile for clueing me in on the docker-entrypoint.sh and the fact that it runs both SQL and shell scripts!
You can simply do the following inside your TR loop:
$(this).find('td').each (function() {
// do your cool stuff
});
An other approach is to use a Virtual JDBC Driver that uses a three-tier architecture: your JDBC code is sent through HTTP to a remote Servlet that filters the JDBC code (configuration & security) before passing it to the MySql JDBC Driver. The result is sent you back through HTTP. There are some free software that use this technique. Just Google "Android JDBC Driver over HTTP".
For the height of a div to be responsive, it must be inside a parent element with a defined height to derive it's relative height from.
If you set the height of the container holding the image and text box on the right, you can subsequently set the heights of its two children to be something like 75% and 25%.
However, this will get a bit tricky when the site layout gets narrower and things will get wonky. Try setting the padding on .contentBg to something like 5.5%.
My suggestion is to use Media Queries to tweak the padding at different screen sizes, then bump everything into a single column when appropriate.
All above answers are correct here is another way with screenshot too.
From Chrome :
You could do
[A1].Value = "'O1/01/13 00:00"
if you really mean to add it as text (note the apostrophe as the first character).
The [A1].Value
is VBA shorthand for Range("A1").Value
.
If you want to enter a date, you could instead do (edited order with thanks to @SiddharthRout):
[A1].NumberFormat = "mm/dd/yyyy hh:mm;@"
[A1].Value = DateValue("01/01/2013 00:00")
My first post... UDF I managed quickly to compile. Usage: Select 3D range as normal and enclose is into quotation marks like below...
=CountIf3D("'StartSheet:EndSheet'!G16:G878";"Criteria")
Advisably sheets to be adjacent to avoid unanticipated results.
Public Function CountIf3D(SheetstoCount As String, CriteriaToUse As Variant)
Dim sStarSheet As String, sEndSheet As String, sAddress As String
Dim lColonPos As Long, lExclaPos As Long, cnt As Long
lColonPos = InStr(SheetstoCount, ":") 'Finding ':' separating sheets
lExclaPos = InStr(SheetstoCount, "!") 'Finding '!' separating address from the sheets
sStarSheet = Mid(SheetstoCount, 2, lColonPos - 2) 'Getting first sheet's name
sEndSheet = Mid(SheetstoCount, lColonPos + 1, lExclaPos - lColonPos - 2) 'Getting last sheet's name
sAddress = Mid(SheetstoCount, lExclaPos + 1, Len(SheetstoCount) - lExclaPos) 'Getting address
cnt = 0
For i = Sheets(sStarSheet).Index To Sheets(sEndSheet).Index
cnt = cnt + Application.CountIf(Sheets(i).Range(sAddress), CriteriaToUse)
Next
CountIf3D = cnt

Just in case you're using .NET 2.0 and don't have access to LINQ:
static T First<T>(IEnumerable<T> items)
{
using(IEnumerator<T> iter = items.GetEnumerator())
{
iter.MoveNext();
return iter.Current;
}
}
This should do what you're looking for...it uses generics so you to get the first item on any type IEnumerable.
Call it like so:
List<string> items = new List<string>() { "A", "B", "C", "D", "E" };
string firstItem = First<string>(items);
Or
int[] items = new int[] { 1, 2, 3, 4, 5 };
int firstItem = First<int>(items);
You could modify it readily enough to mimic .NET 3.5's IEnumerable.ElementAt() extension method:
static T ElementAt<T>(IEnumerable<T> items, int index)
{
using(IEnumerator<T> iter = items.GetEnumerator())
{
for (int i = 0; i <= index; i++, iter.MoveNext()) ;
return iter.Current;
}
}
Calling it like so:
int[] items = { 1, 2, 3, 4, 5 };
int elemIdx = 3;
int item = ElementAt<int>(items, elemIdx);
Of course if you do have access to LINQ, then there are plenty of good answers posted already...

I find a combination of labs
and guides
specification useful in many cases:
You want nothing but a grid and a background:
ggplot(diamonds, mapping = aes(x = clarity)) +
geom_bar(aes(fill = cut)) +
labs(x = NULL, y = NULL) +
guides(x = "none", y = "none")
You want to only suppress the tick-mark label of one or both axes:
ggplot(diamonds, mapping = aes(x = clarity)) +
geom_bar(aes(fill = cut)) +
guides(x = "none", y = "none")

There were two conditions that caused the expression ((var++))
to fail for me:
If I set bash to strict mode (set -euo pipefail
) and if I start my increment at zero (0).
Starting at one (1) is fine but zero causes the increment to return "1" when evaluating "++" which is a non-zero return code failure in strict mode.
I can either use ((var+=1))
or var=$((var+1))
to escape this behavior
You can use the datetime
module for working with dates and times in Python. The strftime
method allows you to produce string representation of dates and times with a format you specify.
>>> import datetime
>>> datetime.date.today().strftime("%B %d, %Y")
'July 23, 2010'
>>> datetime.datetime.now().strftime("%I:%M%p on %B %d, %Y")
'10:36AM on July 23, 2010'

Use the official Angular Update Guide select your current version and the version you wish to upgrade to for the relevant upgrade guide. https://update.angular.io/
See GitHub repository Angular CLI diff for comparing Angular CLI changes. https://github.com/cexbrayat/angular-cli-diff/
UPDATED 26/12/2018:
Use the official Angular Update Guide mentioned in the useful section above. It provides the most up to date information with links to other resources that may be useful during the upgrade.
UPDATED 08/05/2018:
Angular CLI 1.7 introduced ng update
.
ng update
A new Angular CLI command to help simplify keeping your projects up to date with the latest versions. Packages can define logic which will be applied to your projects to ensure usage of latest features as well as making changes to reduce or eliminate the impact related to breaking changes.
Configuration information for ng update can be found here
1.7 to 6 update
CLI 1.7 does not support an automatic v6 update. Manually install @angular/cli via your package manager, then run the update migration schematic to finish the process.
npm install @angular/cli@^6.0.0
ng update @angular/cli --migrate-only --from=1
UPDATED 30/04/2017:
1.0 Update
You should now follow the Angular CLI migration guide
UPDATED 04/03/2017:
RC Update
You should follow the Angular CLI RC migration guide
UPDATED 20/02/2017:
Please be aware 1.0.0-beta.32 has breaking changes and has removed ng init and ng update
The pull request here states the following:
BREAKING CHANGE: Removing the ng init & ng update commands because their current implementation causes more problems than it solves. Update functionality will return to the CLI, until then manual updates of applications will need done.
The angular-cli CHANGELOG.md states the following:
BREAKING CHANGES - @angular/cli: Removing the ng init & ng update commands because their current implementation causes more problems than it solves. Once RC is released, we won't need to use those to update anymore as the step will be as simple as installing the latest version of the CLI.
UPDATED 17/02/2017:
Angular-cli has now been added to the NPM @angular package. You should now replace the above command with the following -
Global package:
npm uninstall -g angular-cli @angular/cli
npm cache clean
npm install -g @angular/cli@latest
Local project package:
rm -rf node_modules dist # On Windows use rmdir /s /q node_modules dist
npm install --save-dev @angular/cli@latest
npm install
ng init
ORIGINAL ANSWER
You should follow the steps from the README.md on GitHub for updating angular via the angular-cli.
Here they are:
Updating angular-cli
To update angular-cli to a new version, you must update both the global package and your project's local package.
Global package:
npm uninstall -g angular-cli
npm cache clean
npm install -g angular-cli@latest
Local project package:
rm -rf node_modules dist tmp # On Windows use rmdir /s /q node_modules dist tmp
npm install --save-dev angular-cli@latest
npm install
ng init
Running ng init
will check for changes in all the auto-generated files created by ng new and allow you to update yours. You are offered four choices for each changed file: y (overwrite), n (don't overwrite), d (show diff between your file and the updated file) and h (help).
Carefully read the diffs for each code file, and either accept the changes or incorporate them manually after ng init finishes.
Like you I also faced many problems implementing OCR in Android, but after much Googling I found the solution, and it surely is the best example of OCR.
Let me explain using step-by-step guidance.
First, download the source code from https://github.com/rmtheis/tess-two.
Import all three projects. After importing you will get an error.
To solve the error you have to create a res
folder in the tess-two project
First, just create res folder in tess-two by tess-two->RightClick->new Folder->Name it "res"
After doing this in all three project the error should be gone.
Now download the source code from https://github.com/rmtheis/android-ocr, here you will get best example.
Now you just need to import it into your workspace, but first you have to download android-ndk from this site:
http://developer.android.com/tools/sdk/ndk/index.html i have windows 7 - 32 bit PC so I have download http://dl.google.com/android/ndk/android-ndk-r9-windows-x86.zip this file
Now extract it suppose I have extract it into E:\Software\android-ndk-r9 so I will set this path on Environment Variable
Right Click on MyComputer->Property->Advance-System-Settings->Advance->Environment Variable-> find PATH on second below Box and set like path like below picture
done it
Now open cmd and go to on D:\Android Workspace\tess-two like below
If you have successfully set up environment variable of NDK then just type ndk-build just like above picture than enter you will not get any kind of error and all file will be compiled successfully:
Now download other source code also from https://github.com/rmtheis/tess-two , and extract and import it and give it name OCRTest, like in my PC which is in D:\Android Workspace\OCRTest
Import test-two in this and run OCRTest and run it; you will get the best example of OCR.
Try this, its working in FF

Don't use CREATE TYPE to return a polymorphic result. Use and abuse the RECORD type instead. Check it out:
CREATE FUNCTION test_ret(a TEXT, b TEXT) RETURNS RECORD AS $$
DECLARE
ret RECORD;
BEGIN
-- Arbitrary expression to change the first parameter
IF LENGTH(a) < LENGTH(b) THEN
SELECT TRUE, a || b, 'a shorter than b' INTO ret;
ELSE
SELECT FALSE, b || a INTO ret;
END IF;
RETURN ret;
END;$$ LANGUAGE plpgsql;
Pay attention to the fact that it can optionally return two or three columns depending on the input.
test=> SELECT test_ret('foo','barbaz');
test_ret
----------------------------------
(t,foobarbaz,"a shorter than b")
(1 row)
test=> SELECT test_ret('barbaz','foo');
test_ret
----------------------------------
(f,foobarbaz)
(1 row)
This does wreak havoc on code, so do use a consistent number of columns, but it's ridiculously handy for returning optional error messages with the first parameter returning the success of the operation. Rewritten using a consistent number of columns:
CREATE FUNCTION test_ret(a TEXT, b TEXT) RETURNS RECORD AS $$
DECLARE
ret RECORD;
BEGIN
-- Note the CASTING being done for the 2nd and 3rd elements of the RECORD
IF LENGTH(a) < LENGTH(b) THEN
ret := (TRUE, (a || b)::TEXT, 'a shorter than b'::TEXT);
ELSE
ret := (FALSE, (b || a)::TEXT, NULL::TEXT);
END IF;
RETURN ret;
END;$$ LANGUAGE plpgsql;
Almost to epic hotness:
test=> SELECT test_ret('foobar','bar');
test_ret
----------------
(f,barfoobar,)
(1 row)
test=> SELECT test_ret('foo','barbaz');
test_ret
----------------------------------
(t,foobarbaz,"a shorter than b")
(1 row)
But how do you split that out in to multiple rows so that your ORM layer of choice can convert the values in to your language of choice's native data types? The hotness:
test=> SELECT a, b, c FROM test_ret('foo','barbaz') AS (a BOOL, b TEXT, c TEXT);
a | b | c
---+-----------+------------------
t | foobarbaz | a shorter than b
(1 row)
test=> SELECT a, b, c FROM test_ret('foobar','bar') AS (a BOOL, b TEXT, c TEXT);
a | b | c
---+-----------+---
f | barfoobar |
(1 row)

If You want make json object from yor model do like this :
foreach (var item in Persons)
{
var jsonObj=["FirstName":"@item.FirstName"]
}
Or Use Json.Net to make json from your model :
string json = JsonConvert.SerializeObject(person);
Overall just add display:block; to your span. You can leave your html unchanged.
You can do it with the following css:
p {

margin-top:0px;
}
p span {
font-size:16px;
font-style: italic;
margin-top:20px;
padding-left:10px;
display:inline-block;

I've heard in my degree classes that a HashTable will place a new entry into the 'next available' bucket if the new Key entry collides with another.
This is actually not true, at least for the Oracle JDK (it is an implementation detail that could vary between different implementations of the API). Instead, each bucket contains a linked list of entries prior to Java 8, and a balanced tree in Java 8 or above.
then how would the HashTable still return the correct Value if this collision occurs when calling for one back with the collision key?
It uses the equals()
to find the actually matching entry.
If I implement my own hashing function and use it as part of a look-up table (i.e. a HashMap or Dictionary), what strategies exist for dealing with collisions?
There are various collision handling strategies with different advantages and disadvantages. Wikipedia's entry on hash tables gives a good overview.
QueueHandler
is native in Python 3.2+, and does exactly this. It is easily replicated in previous versions.
Python docs have two complete examples: Logging to a single file from multiple processes
For those using Python < 3.2, just copy QueueHandler
into your own code from: https://gist.github.com/vsajip/591589 or alternatively import logutils.
Each process (including the parent process) puts its logging on the Queue
, and then a listener
thread or process (one example is provided for each) picks those up and writes them all to a file - no risk of corruption or garbling.
Had the same issue and just figured, website is running under MAMP's php, but when you call in command, it runs mac's(if no bash path modified). you will have issue when mac doesn't have those extensions.
run php -i to find out loaded extensions, and install those one you missed. or run '/Applications/MAMP/bin/php/php5.3.6/bin/php artisan {your command}' to use MAMP's
When I tried to create something simillar to inbox floating action button i thought about creating own custom component.
It would be simple frame layout with fixed height (to contain expanded menu) containing FAB button and 3 more placed under the FAB. when you click on FAB you just simply animate other buttons to translate up from under the FAB.
There are some libraries which do that (for example https://github.com/futuresimple/android-floating-action-button), but it's always more fun if you create it by yourself :)
clean
is its own build lifecycle phase (which can be thought of as an action or task) in Maven. mvn clean install
tells Maven to do the clean
phase in each module before running the install
phase for each module.
What this does is clear any compiled files you have, making sure that you're really compiling each module from scratch.
It happens when you don't properly close the code block:
if (condition){
// your code goes here*
{ // This doesn't close the code block
Correct way:
if (condition){
// your code goes here
} // Close the code block
The body onLoad could be an alternative too:

Be carefully though. If you return Collections.emptyList()
and then try to do some changes with it like add()
or smth like that, u will have an UnsupportedOperationException()
because Collections.emptyList()
returns an immutable object.
Just an idea: Use Python as embeddable scripting language to plot your graphs. Python has a plethora of plotting libraries.
I would NEVER use chars. I’ve had this debate with many people and they always bring up the tired cliché that char is faster. Well I say, how much faster? What are we talking about here, milliseconds, seconds and if so how many? You’re telling me because someone claims its a few milliseconds faster, we should introduce tons of hard to fix bugs into the system?
So here are some issues you will run into:
Every field will be padded, so you end up with code forever that has RTRIMS everywhere. This is also a huge disk space waste for the longer fields.
Now let’s say you have the quintessential example of a char field of just one character but the field is optional. If somebody passes an empty string to that field it becomes one space. So when another application/process queries it, they get one single space, if they don’t use rtrim. We’ve had xml documents, files and other programs, display just one space, in optional fields and break things.
So now you have to ensure that you’re passing nulls and not empty string, to the char field. But that’s NOT the correct use of null. Here is the use of null. Lets say you get a file from a vendor
Name|Gender|City
Bob||Los Angeles
If gender is not specified than you enter Bob, empty string and Los Angeles into the table. Now lets say you get the file and its format changes and gender is no longer included but was in the past.
Name|City
Bob|Seattle
Well now since gender is not included, I would use null. Varchars support this without issues.
Char on the other hand is different. You always have to send null. If you ever send empty string, you will end up with a field that has spaces in it.
I could go on and on with all the bugs I’ve had to fix from chars and in about 20 years of development.
In my case problem was at context.xml file of my project.
The following from context.xml causes the java.lang.AbstractMethodError, since we didn't show the datasource factory.
<Resource name="jdbc/myoracle"
auth="Container"
type="javax.sql.DataSource"
driverClassName="oracle.jdbc.OracleDriver"
url="jdbc:oracle:thin:@(DESCRIPTION = ... "
username="****" password="****" maxActive="10" maxIdle="1"
maxWait="-1" removeAbandoned="true"/>
Simpy adding factory="org.apache.tomcat.jdbc.pool.DataSourceFactory" solved the issue:
<Resource name="jdbc/myoracle"
auth="Container"
factory="org.apache.tomcat.jdbc.pool.DataSourceFactory" type="javax.sql.DataSource"
driverClassName="oracle.jdbc.OracleDriver"
url="jdbc:oracle:thin:@(DESCRIPTION = ... "
username="****" password="****" maxActive="10" maxIdle="1"
maxWait="-1" removeAbandoned="true"/>
To make sure I reproduced the issue several times by removing factory="org.apache.tomcat.jdbc.pool.DataSourceFactory" from Resource
I got here with an MS Access problem.
Backticks are good for MySQL, but they create weird errors, like "Invalid Query Name: Query1" in MS Access, for MS Access only, use square brackets:
It should look like this
SELECT Customer.[Customer ID], Customer.[Full Name] ...
table { width: 100%; }
Will not produce the exact result you are expecting, because of all the margins and paddings used in body. So IF scripts are OKAY, then use Jquery.
$("#tableid").width($(window).width());
If not, use this snippet
<style>
body { margin:0;padding:0; }
</style>
<table width="100%" border="1">
<tr>
<td>Just a Test
</td>
</tr>
</table>
You will notice that the width is perfectly covering the page.
The main thing is too nullify the margin
and padding
as I have shown at the body, then you are set.
Complete checking of a string for null conditions can be a s follows :<\br>
if(mystring) { if([mystring isEqualToString:@""]) { mystring=@"some string"; } } else { //statements }
In Mongoose, a sort can be done in any of the following ways:
Post.find({}).sort('test').exec(function(err, docs) { ... });
Post.find({}).sort([['date', -1]]).exec(function(err, docs) { ... });
Post.find({}).sort({test: 1}).exec(function(err, docs) { ... });
Post.find({}, null, {sort: {date: 1}}, function(err, docs) { ... });
A SELECT INTO
statement creates the table for you. There is no need for the CREATE TABLE
statement before hand.
What is happening is that you create #ivmy_cash_temp1
in your CREATE
statement, then the DB tries to create it for you when you do a SELECT INTO
. This causes an error as it is trying to create a table that you have already created.
Either eliminate the CREATE TABLE
statement or alter your query that fills it to use INSERT INTO SELECT
format.
If you need a unique ID added to your new row then it's best to use SELECT INTO
... since IDENTITY()
only works with this syntax.
You don't have to call the external basename
command. Instead, you could use the following commands:
$ s=/the/path/foo.txt
$ echo "${s##*/}"
foo.txt
$ s=${s##*/}
$ echo "${s%.txt}"
foo
$ echo "${s%.*}"
foo
Note that this solution should work in all recent (post 2004) POSIX compliant shells, (e.g. bash
, dash
, ksh
, etc.).

In my case, it was the UIAlertView on iPad: UIAlertController is Crashed (iPad). I didn't setup sourceView and sourceRect.
First of all to see how many revisions you are behind locally, you should do a git fetch
to make sure you have the latest info from your remote.
The default output of git status
tells you how many revisions you are ahead or behind, but usually I find this too verbose:
$ git status
# On branch master
# Your branch and 'origin/master' have diverged,
# and have 2 and 1 different commit each, respectively.
#
nothing to commit (working directory clean)
I prefer git status -sb
:
$ git status -sb
## master...origin/master [ahead 2, behind 1]
In fact I alias this to simply git s
, and this is the main command I use for checking status.
To see the diff in the "ahead revisions" of master
, I can exclude the "behind revisions" from origin/master
:
git diff master..origin/master^
To see the diff in the "behind revisions" of origin/master
, I can exclude the "ahead revisions" from master
:
git diff origin/master..master^^
If there are 5 revisions ahead or behind it might be easier to write like this:
git diff master..origin/master~5
git diff origin/master..master~5
UPDATE
To see the ahead/behind revisions, the branch must be configured to track another branch. For me this is the default behavior when I clone a remote repository, and after I push a branch with git push -u remotename branchname
. My version is 1.8.4.3, but it's been working like this as long as I remember.
As of version 1.8, you can set the tracking branch like this:
git branch --track test-branch
As of version 1.7, the syntax was different:
git branch --set-upstream test-branch
Disclaimer : I've created fast-xml-parser
I have created fast-xml-parser to parse a XML string into JS/JSON object or intermediate traversal object. It is expected to be compatible in all the browsers (however tested on Chrome, Firefox, and IE only).
Usage
var options = { //default
attrPrefix : "@_",
attrNodeName: false,
textNodeName : "#text",
ignoreNonTextNodeAttr : true,
ignoreTextNodeAttr : true,
ignoreNameSpace : true,
ignoreRootElement : false,
textNodeConversion : true,
textAttrConversion : false,
arrayMode : false
};
if(parser.validate(xmlData)){//optional
var jsonObj = parser.parse(xmlData, options);
}
//Intermediate obj
var tObj = parser.getTraversalObj(xmlData,options);
:
var jsonObj = parser.convertToJson(tObj);
Note: It doesn't use DOM parser but parse the string using RE and convert it into JS/JSON object.
This is the simplest way I can come with.
package main
import "fmt"
func main() {
g := greeting
getFunc(g)
}
func getFunc(f func()) {
f()
}
func greeting() {
fmt.Println("Hello")
}
You pass the exception directly to the logger, e.g.
try {
...
} catch (Exception e) {
log.error( "failed!", e );
}
It's up to log4j to render the stack trace.
The method, as indicated by their technical considerations page, is correct - so you're definitely not doing anything wrong. However, this bug report on Google Code indicate that there is a problem with the fonts Google produced for this, specifically the IE version. This only seems to affect only some fonts, but it's a real bummmer.
The answers on the thread indicate that the problem lies with the files Google's serving up, so there's nothing you can do about it. The author suggest getting the fonts from alternative locations, like FontSquirrel, and serving it locally instead, in which case you might also be interested in sites like the League of Movable Type.
N.B. As of Oct 2010 the issue is reported as fixed and closed on the Google Code bug report.
How to hard reset Visual Studio instance
When developing extensions sometimes you just mess up, others someone else does. If you start getting errors loading even the most mundane extensions, these are the instructions to hard reset your instance.
Close Visual Studio (if you haven’t already).
Open the registry editor (regedit.exe)
Delete the HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\{version}
Delete the HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\{version}_Config
Delete the %LOCALAPPDATA%\Microsoft\VisualStudio\{version} directory.
Enjoy your brand new Visual Studio instance.
If on the other side you want to reset the experimental hive you can do the same to with the ‘{version}Exp’ ones.
Happy coding!

There is nothing a Factory cannot do or does better in comparison with a Service. And vice verse. Factory just seems to be more popular. The reason for that is its convenience in handling private/public members. Service would be more clumsy in this regard. When coding a Service you tend to make your object members public via “this” keyword and may suddenly find out that those public members are not visible to private methods (ie inner functions).
var Service = function(){
//public
this.age = 13;
//private
function getAge(){
return this.age; //private does not see public
}
console.log("age: " + getAge());
};
var s = new Service(); //prints 'age: undefined'
Angular uses the “new” keyword to create a service for you, so the instance Angular passes to the controller will have the same drawback. Of course you may overcome the problem by using this/that:
var Service = function(){
var that = this;
//public
this.age = 13;
//private
function getAge(){
return that.age;
}
console.log("age: " + getAge());
};
var s = new Service();// prints 'age: 13'
But with a large Service constant this\that-ing would make the code poorly readable. Moreover, the Service prototypes will not see private members – only public will be available to them:
var Service = function(){
var name = "George";
};
Service.prototype.getName = function(){
return this.name; //will not see a private member
};
var s = new Service();
console.log("name: " + s.getName());//prints 'name: undefined'
Summing it up, using Factory is more convenient. As Factory does not have these drawbacks. I would recommend using it by default.
If you want to retrieve the key's value if it exists, you can also use
try:
value = a[key]
except KeyError:
# Key is not present
pass
If you want to retrieve a default value when the key does not exist, use
value = a.get(key, default_value)
.
If you want to set the default value at the same time in case the key does not exist, use
value = a.setdefault(key, default_value)
.
For completeness, we should include ConfigParser and configparser which are part of the standard library in Python 2 and 3, respectively. This module reads and writes to a config/ini file and (at least in Python 3) behaves in a lot of ways like a dictionary. It has the added benefit that you can store multiple dictionaries into separate sections of your config/ini file and recall them. Sweet!
Python 2.7.x example.
import ConfigParser
config = ConfigParser.ConfigParser()
dict1 = {'key1':'keyinfo', 'key2':'keyinfo2'}
dict2 = {'k1':'hot', 'k2':'cross', 'k3':'buns'}
dict3 = {'x':1, 'y':2, 'z':3}
# Make each dictionary a separate section in the configuration
config.add_section('dict1')
for key in dict1.keys():
config.set('dict1', key, dict1[key])
config.add_section('dict2')
for key in dict2.keys():
config.set('dict2', key, dict2[key])
config.add_section('dict3')
for key in dict3.keys():
config.set('dict3', key, dict3[key])
# Save the configuration to a file
f = open('config.ini', 'w')
config.write(f)
f.close()
# Read the configuration from a file
config2 = ConfigParser.ConfigParser()
config2.read('config.ini')
dictA = {}
for item in config2.items('dict1'):
dictA[item[0]] = item[1]
dictB = {}
for item in config2.items('dict2'):
dictB[item[0]] = item[1]
dictC = {}
for item in config2.items('dict3'):
dictC[item[0]] = item[1]
print(dictA)
print(dictB)
print(dictC)
Python 3.X example.
import configparser
config = configparser.ConfigParser()
dict1 = {'key1':'keyinfo', 'key2':'keyinfo2'}
dict2 = {'k1':'hot', 'k2':'cross', 'k3':'buns'}
dict3 = {'x':1, 'y':2, 'z':3}
# Make each dictionary a separate section in the configuration
config['dict1'] = dict1
config['dict2'] = dict2
config['dict3'] = dict3
# Save the configuration to a file
f = open('config.ini', 'w')
config.write(f)
f.close()
# Read the configuration from a file
config2 = configparser.ConfigParser()
config2.read('config.ini')
# ConfigParser objects are a lot like dictionaries, but if you really
# want a dictionary you can ask it to convert a section to a dictionary
dictA = dict(config2['dict1'] )
dictB = dict(config2['dict2'] )
dictC = dict(config2['dict3'])
print(dictA)
print(dictB)
print(dictC)
{'key2': 'keyinfo2', 'key1': 'keyinfo'}
{'k1': 'hot', 'k2': 'cross', 'k3': 'buns'}
{'z': '3', 'y': '2', 'x': '1'}
[dict1]
key2 = keyinfo2
key1 = keyinfo
[dict2]
k1 = hot
k2 = cross
k3 = buns
[dict3]
z = 3
y = 2
x = 1

I'm also faced this situation. You can handle above method. but simple if you pass simple_dropdown_item_1line as resource. It will be black color text by default.
This is my code I have achieved in kind of situation.
ArrayAdapter<String> arrAdapter =
new ArrayAdapter<String>(context,android.R.layout.simple_dropdown_item_1line,countryList);
listView.setAdapter(arrAdapter);
Your code below:
setListAdapter(new ArrayAdapter<String>(getApplicationContext(),
android.R.layout.simple_dropdown_item_1line, mStringList));
Actually android.R.layout.simple_dropdown_item_1line is used for dropdown. I urge u to see this layout content once. It just simple textview. thats all. It's property will not affect your task. I checked It works fine.
Is that your actual code? A javascript object (which is what you've given us) does not have a length property, so in this case exampleArray.length
returns undefined rather than 5.
This stackoverflow explains the length differences between an object and an array, and this stackoverflow shows how to get the 'size' of an object.
Array.prototype.find
is not supported in any version of IE

If any of your markn
columns are "AllowNull" then you will need to do a little extra to insure the correct result is returned, this is because 1 NULL value will result in a NULL total.
This is what i would consider to be the correct answer.
SUM(IFNULL(`mark1`, 0) + IFNULL(`mark2`, 0) + IFNULL(`mark3`, 0)) AS `total_marks`
IFNULL will return the 2nd parameter if the 1st is NULL. COALESCE could be used but i prefer to only use it if it is required. See What is the difference bewteen ifnull and coalesce in mysql?
SUM-ing the entire calculation is tidier than SUM-ing each column individually.
SELECT `student`, SUM(IFNULL(`mark1`, 0) + IFNULL(`mark2`, 0) + IFNULL(`mark3`, 0)) AS `total_marks`
FROM student_scorecard
GROUP BY `student`
For a PUT request: HTTP 200 or HTTP 204 should imply "resource updated successfully".
For a DELETE request: HTTP 200 or HTTP 204 should imply "resource deleted successfully". HTTP 202 can also be returned which would imply that the instruction was accepted by the server and the "resource was marked for deletion".
If an existing resource is modified, either the 200 (OK) or 204 (No Content) response codes SHOULD be sent to indicate successful completion of the request.
A successful response SHOULD be 200 (OK) if the response includes an entity describing the status, 202 (Accepted) if the action has not yet been enacted, or 204 (No Content) if the action has been enacted but the response does not include an entity.
Source: W3.org: HTTP/1.1 Method Definitions
HTTP 200 OK: Standard response for successful HTTP requests. The actual response will depend on the request method used.
HTTP 204 No Content: The server successfully processed the request, but is not returning any content
Quick summary, you can do either:
Include the JavaFX modules via --module-path
and --add-modules
like in José's answer.
OR
Once you have JavaFX libraries added to your project (either manually or via maven/gradle import), add the module-info.java
file similar to the one specified in this answer. (Note that this solution makes your app modular, so if you use other libraries, you will also need to add statements to require their modules inside the module-info.java
file).
This answer is a supplement to Jose's answer.
The situation is this:

Exception running application org.jewelsea.demo.javafx.springboot.Main
OK, now you are kind of stuck and have no clue what is going on.
What has actually happened is this:
So it seems everything should be OK. BUT, when you run your application, the code in the JavaFX modules is failing when trying to use reflection to instantiate instances of your application class (when you invoke launch) and your FXML controller classes (when you load FXML). Without some help, this use of reflection can fail in some cases, generating the obscure IllegalAccessError
. This is due to a Java module system security feature which does not allow code from other modules to use reflection on your classes unless you explicitly allow it (and the JavaFX application launcher and FXMLLoader both require reflection in their current implementation in order for them to function correctly).
This is where some of the other answers to this question, which reference module-info.java
, come into the picture.
So let's take a crash course in Java modules:
The key part is this:
4.9. Opens
If we need to allow reflection of private types, but we don't want all of our code exposed, we can use the opens directive to expose specific packages.
But remember, this will open the package up to the entire world, so make sure that is what you want:
module my.module { opens com.my.package; }
So, perhaps you don't want to open your package to the entire world, then you can do:
4.10. Opens … To
Okay, so reflection is great sometimes, but we still want as much security as we can get from encapsulation. We can selectively open our packages to a pre-approved list of modules, in this case, using the opens…to directive:
module my.module { opens com.my.package to moduleOne, moduleTwo, etc.; }
So, you end up creating a src/main/java/module-info.java class which looks like this:
module org.jewelsea.demo.javafx.springboot {
requires javafx.fxml;
requires javafx.controls;
requires javafx.graphics;
opens org.jewelsea.demo.javafx.springboot to javafx.graphics,javafx.fxml;
}
Where, org.jewelsea.demo.javafx.springboot
is the name of the package which contains the JavaFX Application class and JavaFX Controller classes (replace this with the appropriate package name for your application). This tells the Java runtime that it is OK for classes in the javafx.graphics
and javafx.fxml
to invoke reflection on the classes in your org.jewelsea.demo.javafx.springboot
package. Once this is done, and the application is compiled and re-run things will work fine and the IllegalAccessError
generated by JavaFX's use of reflection will no longer occur.
But what if you don't want to create a module-info.java file
If instead of using the the Run button in the top toolbar of IDE to run your application class directly, you instead:
javafx.run
.Run Maven Build
or Debug...
.Then the app will run without the module-info.java
file. I guess this is because the maven plugin is smart enough to dynamically include some kind of settings which allows the app to be reflected on by the JavaFX classes even without a module-info.java
file, though I don't know how this is accomplished.
To get that setting transferred to the Run button in the top toolbar, right-click on the javafx.run
Maven target and choose the option to Create Run/Debug Configuration
for the target. Then you can just choose Run from the top toolbar to execute the Maven target.

It's hard to answer you without the HTML, but in general you can put:
style="width: 50%;"
On either the table cell, or place a div inside the table cell, and put the style on that.
But one problem is "50% of what?" It's 50% of the parent element which may not be what you want.
Post a copy of your HTML and maybe you'll get a better answer.
No, there isn't. The designers of Java are on record as saying they didn't like unsigned ints. Use a BigInteger instead. See this question for details.

This only disables the "Enter" keypress action for input type='text'. Visitors can still use "Enter" key all over the website.
If you want to disable "Enter" for other actions as well, you can add console.log(e); for your your test purposes, and hit F12 in chrome, go to "console" tab and hit "backspace" on the page and look inside it to see what values are returned, then you can target all of those parameters to further enhance the code above to suit your needs for "e.target.nodeName", "e.target.type" and many more...
As others have explained that it is not possible, but here's alternative solution, it requires a little tuning, but it works like datetime column.
I started to think, how I could make formatting possible. I got an idea. What about making trigger for it? I mean, adding column with type char
, and then updating that column using a MySQL trigger. And that worked! I made some research related to triggers, and finally come up with these queries:
CREATE TRIGGER timestampper BEFORE INSERT ON table
FOR EACH
ROW SET NEW.timestamp = DATE_FORMAT(NOW(), '%d-%m-%Y %H:%i:%s');
CREATE TRIGGER timestampper BEFORE UPDATE ON table
FOR EACH
ROW SET NEW.timestamp = DATE_FORMAT(NOW(), '%d-%m-%Y %H:%i:%s');
You can't use TIMESTAMP
or DATETIME
as a column type, because these have their own format, and they update automatically.
So, here's your alternative timestamp or datetime alternative! Hope this helped, at least I'm glad that I got this working.
very simple
$('#label-ID').text("label value which you want to set");
It's a bit late, But easy and effective. Click on About Android Studio, Check the current version, Open build.graddle of Project and put it in front of the class path. e.g Your studio version is 3.5.2, then your classpath should be like that.
classpath 'com.android.tools.build:gradle:3.5.2'
Using Maria-DB and DB-Navigator tool inside IntelliJ, MODIFY Column worked for me instead of Alter Column
Now all clients allow to do it, but it's not pretty simple.

This related question points out a part of the ?read.table
documentation that explains your problem:
If there is a header and the first row contains one fewer field than the number of columns, the first column in the input is used for the row names. Otherwise if row.names is missing, the rows are numbered.
Your header row likely has 1 fewer column than the rest of the file and so read.table
assumes that the first column is the row.names (which must all be unique), not a column (which can contain duplicated values). You can fix this by using one of the following two Solutions:
\t
or ,
) to the front or end of your header row in the source file, or,The choice will depend on the structure of your data.
Example:
Here the header row is interpreted as having one fewer column than the data because the delimiters don't match:
v1,v2,v3 # 3 items!!
a1,a2,a3, # 4 items
b1,b2,b3, # 4 items
This is how it is interpreted by default:
v1,v2,v3 # 3 items!!
a1,a2,a3, # 4 items
b1,b2,b3, # 4 items
The first column (with no header) values are interpreted as row.names: a1
and b1
. If this column contains duplicates, which is entirely possible, then you get the duplicate 'row.names' are not allowed
error.
If you set row.names = FALSE
, the shift doesn't happen, but you still have a mismatching number of items in the header and in the data because the delimiters don't match.
Solution 1 Add trailing delimiter to header:
v1,v2,v3, # 4 items!!
a1,a2,a3, # 4 items
b1,b2,b3, # 4 items
Solution 2 Remove excess trailing delimiter from non-header rows:
v1,v2,v3 # 3 items
a1,a2,a3 # 3 items!!
b1,b2,b3 # 3 items!!
When generating the key, don't forget to concatenate the version and build number to the string you calculate the hash on. That way there won't be a single key that unlocks all everything you ever released.
After you find some keys or patches floating in astalavista.box.sk you'll know that you succeeded in making something popular enough that somebody bothered to crack. Rejoice!
I think this above code will work on LongClicking the listview, not the individual items.
why not use registerForContextMenu(listView)
. and then get the callback in OnCreateContextMenu.
For most use cases this will work same.
Are you using the default controls boolean attribute on the video tag? If so, I believe all the supporting browsers have mute buttons. If you need to wire it up, set .muted to true on the element in javascript (use .prop for jquery because it's an IDL attribute.) The speaker icon on the volume control is the mute button on chrome,ff, safari, and opera for example
I simply write it this way
in the AspectType file:
class AspectType {
//blah blah
}
module.exports = AspectType;
and import it like this:
const AspectType = require('./AspectType');
var aspectType = new AspectType;

Assume we have a function sort(int *arraytobesorted,void (*algorithmchosen)(void))
where it can accept a function pointer as its argument which can be used at some point in sort()
's implementation . Then , here the code that is being addressed by the function pointer algorithmchosen
is called as callback function .
And see the advantage is that we can choose any algorithm like:
1. algorithmchosen = bubblesort
2. algorithmchosen = heapsort
3. algorithmchosen = mergesort ...
Which were, say,have been implemented with the prototype:
1. `void bubblesort(void)`
2. `void heapsort(void)`
3. `void mergesort(void)` ...
This is a concept used in achieving Polymorphism in Object Oriented Programming

Just came across the same problem and the null-coalescing operator with SelectSingleNode worked a treat, assigning null with string.Empty
foreach (XmlNode txElement in txElements)
{
var txStatus = txElement.SelectSingleNode(".//ns:TxSts", nsmgr).InnerText ?? string.Empty;
var endToEndId = txElement.SelectSingleNode(".//ns:OrgnlEndToEndId", nsmgr).InnerText ?? string.Empty;
var paymentAmount = txElement.SelectSingleNode(".//ns:InstdAmt", nsmgr).InnerText ?? string.Empty;
var paymentAmountCcy = txElement.SelectSingleNode(".//ns:InstdAmt", nsmgr).Attributes["Ccy"].Value ?? string.Empty;
var clientId = txElement.SelectSingleNode(".//ns:OrgnlEndToEndId", nsmgr).InnerText ?? string.Empty;
var bankSortCode = txElement.SelectSingleNode(".//ns:OrgnlEndToEndId", nsmgr).InnerText ?? string.Empty;
//TODO finish Object creation and Upsert DB
