Thing that did it for me was to add this to my mime_types.rb initializer:
Rack::Mime::MIME_TYPES['.woff'] = 'font/woff'
and wipe out the cache
rake tmp:cache:clear
before restarting the server.

After generation of woff files, you have to define font-family, which can be used later in all your css styles. Below is the code to define font families (for normal, bold, bold-italic, italic) typefaces. It is assumed, that there are 4 *.woff files (for mentioned typefaces), placed in fonts
subdirectory.
In CSS code:
@font-face {
font-family: "myfont";
src: url("fonts/awesome-font.woff") format('woff');
}
@font-face {
font-family: "myfont";
src: url("fonts/awesome-font-bold.woff") format('woff');
font-weight: bold;
}
@font-face {
font-family: "myfont";
src: url("fonts/awesome-font-boldoblique.woff") format('woff');
font-weight: bold;
font-style: italic;
}
@font-face {
font-family: "myfont";
src: url("fonts/awesome-font-oblique.woff") format('woff');
font-style: italic;
}
After having that definitions, you can just write, for example,
In HTML code:
<div class="mydiv">
<b>this will be written with awesome-font-bold.woff</b>
<br/>
<b><i>this will be written with awesome-font-boldoblique.woff</i></b>
<br/>
<i>this will be written with awesome-font-oblique.woff</i>
<br/>
this will be written with awesome-font.woff
</div>
In CSS code:
.mydiv {
font-family: myfont
}
The good tool for generation woff files, which can be included in CSS stylesheets is located here. Not all woff files work correctly under latest Firefox versions, and this generator produces 'correct' fonts.
http://dev.w3.org/webfonts/WOFF2/spec/#IMT
It seem that w3c switched it to font/woff2
I see there is some discussion about the proper mime type. In the link we read:
This document defines a top-level MIME type "font" ...
... the officially defined IANA subtypes such as "application/font-woff" ...
The members of the W3C WebFonts WG believe the use of "application" top-level type is not ideal.
and later
6.5. WOFF 2.0
Type name:
font
Subtype name:
woff2
So proposition from W3C differs from IANA.
We can see that it also differs from woff type: http://dev.w3.org/webfonts/WOFF/spec/#IMT where we read:
Type name:
application
Subtype name:
font-woff
which is
application/font-woff
The answer to this post was very helpful and a big time saver. However, I found that when using FontAwesome 4.50
, I had to add an additional configuration for woff2
type of extension also as shown below else requests for woff2
type was giving a 404 error in Chrome's Developer Tools under Console> Errors.
According to the comment by S.Serp, the below configuration should be put within <system.webServer>
tag.
<staticContent>
<remove fileExtension=".woff" />
<!-- In case IIS already has this mime type -->
<mimeMap fileExtension=".woff" mimeType="application/x-font-woff" />
<remove fileExtension=".woff2" />
<!-- In case IIS already has this mime type -->
<mimeMap fileExtension=".woff2" mimeType="application/x-font-woff2" />

I had this error, I looked into a log file C:\...\mysql\data\VM-IIS-Server.err and found this

You can skip the complex Canvas manipulation and do this entirely with Drawables, using LayerDrawable
. You have one of two choices: You can either define it in XML then simply set the image, or you can configure a LayerDrawable
dynamically in code.
Solution #1 (via XML):
Create a new Drawable XML file, let's call it layer.xml
:
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@drawable/t" />
<item android:drawable="@drawable/tt" />
</layer-list>
Now set the image using that Drawable:
testimage.setImageDrawable(getResources().getDrawable(R.layout.layer));
Solution #2 (dynamic):
Resources r = getResources();
Drawable[] layers = new Drawable[2];
layers[0] = r.getDrawable(R.drawable.t);
layers[1] = r.getDrawable(R.drawable.tt);
LayerDrawable layerDrawable = new LayerDrawable(layers);
testimage.setImageDrawable(layerDrawable);
(I haven't tested this code so there may be a mistake, but this general outline should work.)
firstOrCreate()
checks for all the arguments to be present before it finds
a match. If not all arguments match, then a new instance of the model will be created.
If you only want to check on a specific field, then use firstOrCreate(['field_name' => 'value'])
with only one item in the array. This will return the first item that matches, or create a new one if not matches are found.
The difference between firstOrCreate()
and firstOrNew()
:
firstOrCreate()
will automatically create a new entry in the database if there is not match found. Otherwise it will give you the matched item.firstOrNew()
will give you a new model instance to work with if not match was found, but will only be saved to the database when you explicitly do so (calling save()
on the model). Otherwise it will give you the matched item.Choosing between one or the other depends on what you want to do. If you want to modify the model instance before it is saved for the first time (e.g. setting a name
or some mandatory field), you should use firstOrNew()
. If you can just use the arguments to immediately create a new model instance in the database without modifying it, you can use firstOrCreate()
.
I would prevent loops in general if i can, set approaches are much more efficient:
INSERT INTO tblFoo
SELECT TOP (300) n = ROW_NUMBER()OVER (ORDER BY [object_id])
FROM sys.all_objects ORDER BY n;
Use these:
Then you will get the page you want (more options than the admin page) with privileges.
Convert your x-axis data from text to datetime.datetime
, use datetime.strptime
:
>>> from datetime import datetime
>>> datetime.strptime("2012-may-31 19:00", "%Y-%b-%d %H:%M")
datetime.datetime(2012, 5, 31, 19, 0)
This is an example of how to plot data once you have an array of datetimes:
import matplotlib.pyplot as plt
import datetime
import numpy as np
x = np.array([datetime.datetime(2013, 9, 28, i, 0) for i in range(24)])
y = np.random.randint(100, size=x.shape)
plt.plot(x,y)
plt.show()
You can implement a SoapExtension that logs the full request and response to a log file. You can then enable the SoapExtension in the web.config, which makes it easy to turn on/off for debugging purposes. Here is an example that I have found and modified for my own use, in my case the logging was done by log4net but you can replace the log methods with your own.
public class SoapLoggerExtension : SoapExtension
{
private static readonly ILog log = LogManager.GetLogger(MethodBase.GetCurrentMethod().DeclaringType);
private Stream oldStream;
private Stream newStream;
public override object GetInitializer(LogicalMethodInfo methodInfo, SoapExtensionAttribute attribute)
{
return null;
}
public override object GetInitializer(Type serviceType)
{
return null;
}
public override void Initialize(object initializer)
{
}
public override System.IO.Stream ChainStream(System.IO.Stream stream)
{
oldStream = stream;
newStream = new MemoryStream();
return newStream;
}
public override void ProcessMessage(SoapMessage message)
{
switch (message.Stage)
{
case SoapMessageStage.BeforeSerialize:
break;
case SoapMessageStage.AfterSerialize:
Log(message, "AfterSerialize");
CopyStream(newStream, oldStream);
newStream.Position = 0;
break;
case SoapMessageStage.BeforeDeserialize:
CopyStream(oldStream, newStream);
Log(message, "BeforeDeserialize");
break;
case SoapMessageStage.AfterDeserialize:
break;
}
}
public void Log(SoapMessage message, string stage)
{
newStream.Position = 0;
string contents = (message is SoapServerMessage) ? "SoapRequest " : "SoapResponse ";
contents += stage + ";";
StreamReader reader = new StreamReader(newStream);
contents += reader.ReadToEnd();
newStream.Position = 0;
log.Debug(contents);
}
void ReturnStream()
{
CopyAndReverse(newStream, oldStream);
}
void ReceiveStream()
{
CopyAndReverse(newStream, oldStream);
}
public void ReverseIncomingStream()
{
ReverseStream(newStream);
}
public void ReverseOutgoingStream()
{
ReverseStream(newStream);
}
public void ReverseStream(Stream stream)
{
TextReader tr = new StreamReader(stream);
string str = tr.ReadToEnd();
char[] data = str.ToCharArray();
Array.Reverse(data);
string strReversed = new string(data);
TextWriter tw = new StreamWriter(stream);
stream.Position = 0;
tw.Write(strReversed);
tw.Flush();
}
void CopyAndReverse(Stream from, Stream to)
{
TextReader tr = new StreamReader(from);
TextWriter tw = new StreamWriter(to);
string str = tr.ReadToEnd();
char[] data = str.ToCharArray();
Array.Reverse(data);
string strReversed = new string(data);
tw.Write(strReversed);
tw.Flush();
}
private void CopyStream(Stream fromStream, Stream toStream)
{
try
{
StreamReader sr = new StreamReader(fromStream);
StreamWriter sw = new StreamWriter(toStream);
sw.WriteLine(sr.ReadToEnd());
sw.Flush();
}
catch (Exception ex)
{
string message = String.Format("CopyStream failed because: {0}", ex.Message);
log.Error(message, ex);
}
}
}
[AttributeUsage(AttributeTargets.Method)]
public class SoapLoggerExtensionAttribute : SoapExtensionAttribute
{
private int priority = 1;
public override int Priority
{
get { return priority; }
set { priority = value; }
}
public override System.Type ExtensionType
{
get { return typeof (SoapLoggerExtension); }
}
}
You then add the following section to your web.config where YourNamespace and YourAssembly point to the class and assembly of your SoapExtension:
<webServices>
<soapExtensionTypes>
<add type="YourNamespace.SoapLoggerExtension, YourAssembly"
priority="1" group="0" />
</soapExtensionTypes>
</webServices>
I find the answer from @Austin Phillips is spot on. One small improvement I'd do is to add -o (to ignore the pid of the script itself) and match for the script with basename (ie same code can be put into any script):
if pidof -x "`basename $0`" -o $$ >/dev/null; then
echo "Process already running"
fi
I use <span>
in the first column header:
<span> |
--- | ---
Value | Value
Value | Value
It creates an empty header with border, but with 1/2 the size.
I've found some success with this:
/^((ftp|http|https):\/\/)?www\.([A-z]+)\.([A-z]{2,})/
It's obviously not perfect but it handled my cases pretty well
If you happen to have AWS S3 that works like a charm also. Well. Relatively speaking :-)
Create a bucket for your ad hocs in AWS, add an index file (it can just be a blank index.html file) then using a client that can connect to S3 like CyberDuck or Coda (I used Coda - where you'd select Add Site to get a connection window) then set the connections like the attached:
Then build your enterprise ad hoc in XCode and make sure you use https://s3.amazonaws.com/your-bucket-name/your-ad-hoc-folder/your-app.ipa as the Application URL, and upload it to your new S3 bucket directory.
Your itms link should match, i.e. itms-services://?action=download-manifest&url=https://s3.amazonaws.com/your-bucket-name/your-ad-hoc-folder/your-app.plist
And voilá.
This is only for generic AWS URLs - I haven't tried with custom URLs on AWS so you might have to do a few things differently.
I was determined to try to make James Webster's solution above work, but I couldn't get it to work with Plesk.
Mine got solved by enabling multiDex for debug builds.

}
I'm not expert enough in the inner workings of Postgres to know why your query with the double condition in the WHERE
clause be not working. But one way to get around this would be to use a UNION
of the two queries which you know do work:
SELECT * FROM table_name WHERE boolean_column IS NULL
UNION
SELECT * FROM table_name WHERE boolean_column = FALSE
You could also try using COALESCE
:
SELECT * FROM table_name WHERE COALESCE(boolean_column, FALSE) = FALSE
This second query will replace all NULL
values with FALSE
and then compare against FALSE
in the WHERE
condition.
Call the pd.DataFrame
constructor directly:
df = pd.DataFrame(table, columns=headers)
df
Heading1 Heading2
0 1 2

<activity android:name="[packagename optional].ActivityClassName"></activity>
Simply adding the activity which we want to switch to should be placed in the manifest file
MockitoAnnotations & the runner have been well discussed above, so I'm going to throw in my tuppence for the unloved:
XXX mockedXxx = mock(XXX.class);
I use this because I find it a little bit more descriptive and I prefer (not out right ban) unit tests not to use member variables as I like my tests to be (as much as they can be) self contained.
After placing the jar file in desired location, you need to add the jar file by right click on
Project --> properties --> Java Build Path --> Libraries --> Add Jar.
I figured it out! The steps make it look like it will take more effort than it actually does.
These instructions are for creating a project from scratch. If you have existing Python scripts that you wish to include in this project, you will obviously need to slightly deviate from these instructions.
If you find that these instructions no longer work or are unclear due to changes in Xcode updates, please let me know. I will make the necessary corrections.
Note that if you open the "Utilities" panel, with the "Show the File inspector" tab active, the file type is automatically set to "Default - Python script". Feel free to look through all the file type options it has, to gain an idea as to what all it is capable of doing. The method above can be applied to any interpreted language. As of right now, I have yet to figure out exactly how to get it to work with Java; then again, I haven't done too much research. Surely there is some documentation floating around on the web about all of this.
If you do not have administrative privileges or are not in the Developer group, you can still use Xcode for Python programming (but you still won't be able to develop in languages that require compiling). Instead of using the play button, in the menu bar, click "Product" ? "Perform Action" ? "Run Without Building" or simply use the keyboard shortcut ^?R.
To change the text encoding, line endings, and/or indentation settings, open the "Utilities" panel and click "Show the File inspector" tab active. There, you will find these settings.
For more information about Xcode's build settings, there is no better source than this. I'd be interested in hearing from somebody who got this to work with unsupported compiled languages. This process should work for any other interpreted language. Just be sure to change Step 5 and Step 16 accordingly.
Check the username credential used to login to the database. (persistence.xml ??). The problem mostly is, the username\password used to login to the database, does not have visiblity to the object (table_name in this case). ( try logging in to sql developer, using the same username\password available in your data source)
EncodedParams variable is redefined as params variable will not work. You need to have same predefined call to variable, otherwise it looks possible with a little more work. Cheers! json is not used to its full capabilities in php there are better ways to call json which I don't recall at the moment.
Following line in above code is not working
DB_PASSWORD=$(eval echo ${DB_PASSWORD} | base64 --decode)
Correct line is:
DB_PASSWORD=`echo $PASSWORD|base64 -d`
And save the password in other file as PASSWORD.
I faced the issue when i was using ZBar for scanning in tabs. Camera orientation issue. Using below code i was able to resolve issue. This is not the whole code snippet, Please take only help from this.

touchstart or touchend are not good, because if you scroll the page, the device do stuff. So, if I want close a window with tap or click outside the element, and scroll the window, I've done:
$(document).on('touchstart', function() {
documentClick = true;
});
$(document).on('touchmove', function() {
documentClick = false;
});
$(document).on('click touchend', function(event) {
if (event.type == "click") documentClick = true;
if (documentClick){
doStuff();
}
});
Seems that tensorflow only work on python 3.5 at the moment, try to run this command before running the pip install
conda create --name tensorflow python=3.5
After this running the following lines :
For cpu :
pip install --ignore-installed --upgrade https://storage.googleapis.com/tensorflow/windows/cpu/tensorflow-1.1.0-cp35-cp35m-win_amd64.whl
For gpu :
pip install --ignore-installed --upgrade https://storage.googleapis.com/tensorflow/windows/gpu/tensorflow_gpu-1.1.0-cp35-cp35m-win_amd64.whl
Should work like a charm,

I've found that this error is also generated if the document is empty. In this case it's also because there is no root element - but the error message "Extra content and the end of the document" is misleading in this situation.
Nesting block level elements in anchors is not invalid anymore in HTML5. See http://html5doctor.com/block-level-links-in-html-5/ and http://www.w3.org/TR/html5/the-a-element.html.
I'm not saying you should use it, but in HTML5 it's fine to use <a href="#"><div></div></a>
.
The accepted answer is otherwise the best one. Using JavaScript like others suggested is also bad because it would make the "link" inaccessible (to users without JavaScript, which includes search engines and others).
^[A-Za-z](\W|\w)*
(\W|\w)
will ensure that every subsequent letter is word(\w
) or non word(\W
)
instead of (\W|\w)*
you can also use .*
where .
means absolutely anything just like (\w|\W)
For Visual Studio Code:
launch.json
file"args": ["some argument", "another one"],
This is cleaner and will put in a csv.
Import-Module ActiveDirectory
$Groups = (Get-AdGroup -filter * | Where {$_.name -like "**"} | select name -expandproperty name)
$Table = @()
$Record = [ordered]@{
"Group Name" = ""
"Name" = ""
"Username" = ""
}
Foreach ($Group in $Groups)
{
$Arrayofmembers = Get-ADGroupMember -identity $Group | select name,samaccountname
foreach ($Member in $Arrayofmembers)
{
$Record."Group Name" = $Group
$Record."Name" = $Member.name
$Record."UserName" = $Member.samaccountname
$objRecord = New-Object PSObject -property $Record
$Table += $objrecord
}
}
$Table | export-csv "C:\temp\SecurityGroups.csv" -NoTypeInformation
[a-zA-Z]
should do that just fine.
You can reference the cheat sheet.
Add this to your CSS:

if somehow you don't wanna use String split method then you can use StringTokenizer class in Java as..
StringTokenizer tokens = new StringTokenizer("Hello I'm your String", " ");
String[] splited = new String[tokens.countTokens()];
int index = 0;
while(tokens.hasMoreTokens()){
splited[index] = tokens.nextToken();
++index;
}
I know the question is already answered, but I find that the existing answers are not valid:
they will return True for linked tables with a non working back-end.
Using DCount can be much slower, but is more reliable.
Function IsTable(sTblName As String) As Boolean
'does table exists and work ?
'note: finding the name in the TableDefs collection is not enough,
' since the backend might be invalid or missing
On Error GoTo hell

Exit Function

I developed an inelegant solution. Consider that we have the X axis and also a list of labels for each point in X.
Example:import matplotlib.pyplot as plt
x = [0,1,2,3,4,5]
y = [10,20,15,18,7,19]
xlabels = ['jan','feb','mar','apr','may','jun']
Let's say that I want to show ticks labels only for 'feb' and 'jun'
xlabelsnew = []
for i in xlabels:
if i not in ['feb','jun']:
i = ' '
xlabelsnew.append(i)
else:
xlabelsnew.append(i)
Good, now we have a fake list of labels. First, we plotted the original version.
plt.plot(x,y)
plt.xticks(range(0,len(x)),xlabels,rotation=45)
plt.show()
Now, the modified version.
plt.plot(x,y)
plt.xticks(range(0,len(x)),xlabelsnew,rotation=45)
plt.show()
View
objects are the basic building blocks of User Interface(UI) elements in Android.View
is a simple rectangle box which responds to the user's actions.EditText
, Button
, CheckBox
etc..View
refers to the android.view.View
class, which is the base class of all UI classes. ViewGroup
is the invisible container. It holds View
and ViewGroup
LinearLayout
is the ViewGroup
that contains Button(View), and other Layouts also.ViewGroup
is the base class for Layouts.In my opinion, you should not expect too much from volatile
. To illustrate, look at the example in Nils Pipenbrinck's highly-voted answer.
I would say, his example is not suitable for volatile
. volatile
is only used to:
prevent the compiler from making useful and desirable optimizations. It is nothing about the thread safe, atomic access or even memory order.
In that example:
void SendCommand (volatile MyHardwareGadget * gadget, int command, int data)
{
// wait while the gadget is busy:
while (gadget->isbusy)
{
// do nothing here.
}
// set data first:
gadget->data = data;
// writing the command starts the action:
gadget->command = command;
}
the gadget->data = data
before gadget->command = command
only is only guaranteed in compiled code by compiler. At running time, the processor still possibly reorders the data and command assignment, regarding to the processor architecture. The hardware could get the wrong data(suppose gadget is mapped to hardware I/O). The memory barrier is needed between data and command assignment.
In a php section before the HTML section, use sprinf() to create a constant string from the variables:
$mystuff = sprinf("My name is %s and my mother's name is %s","Suzy","Caroline");
Then in the HTML section you can do whatever you like, such as:
<p>$mystuff</p>
52e 1326 ERROR_LOGON_FAILURE
Returns when username is valid but password/credential is invalid. Will prevent most other errors from being displayed as noted.

Another option is to use mouse, right click on "x reference". Context menu "CodeLens Options" will appear, saving all the navigation headache.
I use the following to create a temp exact as the table but without the identity:
SELECT TOP 0 CONVERT(INT,0)myid,* INTO #temp FROM originaltable
ALTER TABLE #temp DROP COLUMN id
EXEC tempdb.sys.sp_rename N'#temp.myid', N'id', N'COLUMN'
Gets a warning about renames but no big deal. I use this on production class systems. Helps make sure the copy will follow any future table modifications and the temp produced is capable of getting rows additional times within a task. Please note that the PK constraint is also removed - if you need it you can add it at the end.
git reset --hard
will force the working directory back to the last commit and delete new/changed files.

getElementById returns either a reference to an element with an id matching the argument, or null if no such element exists in the document.
getElementsByName() (note the plural Elements) returns a (possibly empty) HTMLCollection of the elements with a name matching the argument. Note that IE treats the name and id attributes and properties as the same thing, so getElementsByName will return elements with matching id also.
getElementsByTagName is similar but returns a NodeList. It's all there in the relevant specifications.
I'd like to expand on Obertklep's answer. In his example it is an NPM module called body-parser
which is doing most of the work. Where he puts req.body.name
, I believe he/she is using body-parser
to get the contents of the name attribute(s) received when the form is submitted.
If you do not want to use Express, use querystring
which is a built-in Node module. See the answers in the link below for an example of how to use querystring
.
It might help to look at this answer, which is very similar to your quest.

Dim sheet, zoom_coef, area, chartobj
Dim sFilePath As String
Dim sView As String
'Captures current window view
sView = ActiveWindow.View
'Sets the current view to normal so there are no "Page X" overlays on the image
ActiveWindow.View = xlNormalView
'Temporarily disable screen updating
Application.ScreenUpdating = False
Set sheet = ActiveSheet
'Set the file path to export the image to the user's desktop
'I have to give credit to Kyle for this solution, found it here:
'http://stackoverflow.com/questions/17551238/vba-how-to-save-excel-workbook-to-desktop-regardless-of-user
'sFilePath = CreateObject("WScript.Shell").specialfolders("Desktop") & "\" & ActiveSheet.Name & ".png"

dim FileID as string
FileID=inputbox("Type a file name","Filename...?",ActiveSheet.Name)

As of HTML5, the only restrictions on the value of an ID are:
Similar rules apply to classes (except for the uniqueness, of course).
So the value can be all digits, just one digit, just punctuation characters, include special characters, whatever. Just no whitespace. This is very different from HTML4.
In HTML 4, ID values must begin with a letter, which can then be followed only by letters, digits, hyphens, underscores, colons and periods.
In HTML5 these are valid:
<div id="999"> ... </div>
<div id="#%LV-||"> ... </div>
<div id="____V"> ... </div>
<div id="??"> ... </div>
<div id="?"> ... </div>
<div id="{}"> ... </div>
<div id="©"> ... </div>
<div id="??¤?€~¥"> ... </div>
Just bear in mind that using numbers, punctuation or special characters in the value of an ID may cause trouble in other contexts (e.g., CSS, JavaScript, regex).
For example, the following ID is valid in HTML5:
<div id="9lions"> ... </div>
However, it is invalid in CSS:
From the CSS2.1 spec:
In CSS, identifiers (including element names, classes, and IDs in selectors) can contain only the characters [a-zA-Z0-9] and ISO 10646 characters U+00A0 and higher, plus the hyphen (-) and the underscore (_); they cannot start with a digit, two hyphens, or a hyphen followed by a digit.
In most cases you may be able to escape characters in contexts where they have restrictions or special meaning.
W3C References
HTML5
The
id
attribute specifies its element's unique identifier (ID).The value must be unique amongst all the IDs in the element's home subtree and must contain at least one character. The value must not contain any space characters.
Note: There are no other restrictions on what form an ID can take; in particular, IDs can consist of just digits, start with a digit, start with an underscore, consist of just punctuation, etc.
The attribute, if specified, must have a value that is a set of space-separated tokens representing the various classes that the element belongs to.
The classes that an HTML element has assigned to it consists of all the classes returned when the value of the class attribute is split on spaces. (Duplicates are ignored.)
There are no additional restrictions on the tokens authors can use in the class attribute, but authors are encouraged to use values that describe the nature of the content, rather than values that describe the desired presentation of the content.
It seems to me the easiest way to use the following:
wget https://github.com/name/folder/file.zip?raw=true
StringListName = ObjectListName.stream().map( m -> m.toString() ).collect( Collectors.toList() );
Atomic collections are accessible by $
Recursive collections are not. Rather the [[ ]]
is used
Browse[1]> is.atomic(list())
[1] FALSE
Browse[1]> is.atomic(data.frame())
[1] FALSE
Browse[1]> is.atomic(class(list(foo="bar")))
[1] TRUE
Browse[1]> is.atomic(c(" lang "))
[1] TRUE
R can be funny sometimes
a = list(1,2,3)
b = data.frame(a)
d = rbind("?",c(b))
e = exp(1)
f = list(d)
print(data.frame(c(list(f,e))))
X1 X2 X3 X2.71828182845905
1 ? ? ? 2.718282
2 1 2 3 2.718282
Expanding on what others have said I will give a short example.
If you have a 1D array ...
>>> import numpy as np
>>> x = np.arange(4) # array([0, 1, 2, 3])
>>> x[::-1] # returns a view
Out[1]:
array([3, 2, 1, 0])
But if you are working with a 2D array ...
>>> x = np.arange(10).reshape(2, 5)
>>> x
Out[2]:
array([[0, 1, 2, 3, 4],
[5, 6, 7, 8, 9]])
>>> x[::-1] # returns a view:
Out[3]: array([[5, 6, 7, 8, 9],
[0, 1, 2, 3, 4]])
This does not actually reverse the Matrix.
Should use np.flip to actually reverse the elements
>>> np.flip(x)
Out[4]: array([[9, 8, 7, 6, 5],
[4, 3, 2, 1, 0]])
If you want to print the elements of a matrix one-by-one use flat along with flip
>>> for el in np.flip(x).flat:
>>> print(el, end = ' ')
9 8 7 6 5 4 3 2 1 0
Just add a new datafile for the existing tablespace
ALTER TABLESPACE LEGAL_DATA ADD DATAFILE '/u01/oradata/userdata03.dbf' SIZE 200M;
To find out the location and size of your data files:
SELECT FILE_NAME, BYTES FROM DBA_DATA_FILES WHERE TABLESPACE_NAME = 'LEGAL_DATA';
Use double quotes instead of single quotes
e.g. echo "$foo"
as opposed to echo '$foo'
If you configured your pipeline to accept parameters using the Build with Parameters option, those parameters are accessible as Groovy variables of the same name. See Here.
You can drop the semicolon (;
), drop the parentheses (( and )
), and use single quotes ('
) instead of double ("
) if you do not need to perform variable substitutions. See Here. This clued me into my problem, though I've found that only the double ("
) is required to make it work.
Use:
select * from mytest
EXEC sp_rename 'mytest.eid', 'id', 'COLUMN'
alter table mytest add id int not null identity(1,1)
update mytset set eid=id
ALTER TABLE mytest DROP COLUMN eid
ALTER TABLE [dbo].[yourtablename] ADD DEFAULT (getdate()) FOR [yourfieldname]
It's working 100%.
webRequest.ContentType = "application/x-www-form-urlencoded";
Where does application/x-www-form-urlencoded's name come from?
If you send HTTP GET request, you can use query parameters as follows:
http://example.com/path/to/page
?name=ferret&color=purple
The content of the fields is encoded as a query string. The application/x-www-form-
urlencoded
's name come from the previous url query parameter but the query parameters is
in where the body of request instead of url.
The whole form data is sent as a long query string.The query string contains name- value pairs separated by & character
e.g. field1=value1&field2=value2
It can be simple request called simple - don't trigger a preflight check
Simple request must have some properties. You can look here for more info. One of them is that there are only three values allowed for Content-Type header for simple requests
3.For mostly flat param trees, application/x-www-form-urlencoded is tried and tested.
request.ContentType = "application/json; charset=utf-8";
axios and superagent, two of the more popular npm HTTP libraries, work with JSON bodies by default.
{ "id": 1, "name": "Foo", "price": 123, "tags": [ "Bar", "Eek" ], "stock": { "warehouse": 300, "retail": 20 } }
Now, if the request isn't simple request, the browser automatically sends a HTTP request before the original one by OPTIONS method to check whether it is safe to send the original request. If itis ok, Then send actual request. You can look here for more info.
My solution using C++11 regex (#include <regex>
), it can be used for more precise check, like unsigned int
, double
etc:
static const std::regex INT_TYPE("[+-]?[0-9]+");
static const std::regex UNSIGNED_INT_TYPE("[+]?[0-9]+");
static const std::regex DOUBLE_TYPE("[+-]?[0-9]+[.]?[0-9]+");
static const std::regex UNSIGNED_DOUBLE_TYPE("[+]?[0-9]+[.]?[0-9]+");
bool isIntegerType(const std::string& str_)
{
return std::regex_match(str_, INT_TYPE);
}
bool isUnsignedIntegerType(const std::string& str_)
{
return std::regex_match(str_, UNSIGNED_INT_TYPE);
}
bool isDoubleType(const std::string& str_)
{
return std::regex_match(str_, DOUBLE_TYPE);
}
bool isUnsignedDoubleType(const std::string& str_)
{
return std::regex_match(str_, UNSIGNED_DOUBLE_TYPE);
}
You can find this code at http://ideone.com/lyDtfi, this can be easily modified to meet the requirements.
Angular adds this to keep track of your changes, so it knows when it needs to update the DOM.
If you use angular.toJson(obj)
instead of JSON.stringify(obj)
then Angular will strip out these internal-use values for you.
Also, if you change your repeat expression to use the track by {uniqueProperty}
suffix, Angular won't have to add $$hashKey
at all. For example
<ul>
<li ng-repeat="link in navLinks track by link.href">
<a ng-href="link.href">{{link.title}}</a>
</li>
</ul>
Just always remember you need the "link." part of the expression - I always tend to forget that. Just track by href
will surely not work.
There are two ways to do it.
In the method that opens the dialog, pass in the following configuration option disableClose
as the second parameter in MatDialog#open()
and set it to true
:
export class AppComponent {
constructor(private dialog: MatDialog){}
openDialog() {
this.dialog.open(DialogComponent, { disableClose: true });
}
}
Alternatively, do it in the dialog component itself.
export class DialogComponent {
constructor(private dialogRef: MatDialogRef<DialogComponent>){
dialogRef.disableClose = true;
}
}
Here's what you're looking for:
And here's a Stackblitz demo
Here's some other use cases and code snippets of how to implement them.
As what @MarcBrazeau said in the comment below my answer, you can allow the esc key to close the modal but still disallow clicking outside the modal. Use this code on your dialog component:
import { Component, OnInit, HostListener } from '@angular/core';
import { MatDialogRef } from '@angular/material';
@Component({
selector: 'app-third-dialog',
templateUrl: './third-dialog.component.html'
})
export class ThirdDialogComponent {
constructor(private dialogRef: MatDialogRef<ThirdDialogComponent>) {
}
@HostListener('window:keyup.esc') onKeyUp() {
this.dialogRef.close();
}
}
P.S. This is an answer which originated from this answer, where the demo was based on this answer.
To prevent the esc key from closing the dialog but allow clicking on the backdrop to close, I've adapted Marc's answer, as well as using MatDialogRef#backdropClick
to listen for click events to the backdrop.
Initially, the dialog will have the configuration option disableClose
set as true
. This ensures that the esc
keypress, as well as clicking on the backdrop will not cause the dialog to close.
Afterwards, subscribe to the MatDialogRef#backdropClick
method (which emits when the backdrop gets clicked and returns as a MouseEvent
).
Anyways, enough technical talk. Here's the code:
openDialog() {
let dialogRef = this.dialog.open(DialogComponent, { disableClose: true });
/*
Subscribe to events emitted when the backdrop is clicked
NOTE: Since we won't actually be using the `MouseEvent` event, we'll just use an underscore here
See https://stackoverflow.com/a/41086381 for more info
*/
dialogRef.backdropClick().subscribe(() => {
// Close the dialog
dialogRef.close();
})
// ...
}
Alternatively, this can be done in the dialog component:
export class DialogComponent {
constructor(private dialogRef: MatDialogRef<DialogComponent>) {
dialogRef.disableClose = true;
/*
Subscribe to events emitted when the backdrop is clicked
NOTE: Since we won't actually be using the `MouseEvent` event, we'll just use an underscore here
See https://stackoverflow.com/a/41086381 for more info
*/
dialogRef.backdropClick().subscribe(() => {
// Close the dialog
dialogRef.close();
})
}
}
Give the table a class name and then you target the td's with the following:
table.classname td {
font-size: 90%;
}
copy from subfolder to subfolder
if not exist "$(ProjectDir)$(OutDir)subfolder" mkdir "$(ProjectDir)$(OutDir)subfolder"
copy "$(ProjectDir)subfolder\" "$(ProjectDir)$(OutDir)subfolder\"

Change draggable
attribute from
<span draggable="true">Label</span>
to
<span draggable="false">Label</span>
If you are using the hex codes, you can add two more digits at the end of the code to represent the alpha channel:
E.g. half-transparency red:
plot(1:100, main="Example of Plot With Transparency")
lines(1:100 + sin(1:100*2*pi/(20)), col='#FF000088', lwd=4)
mtext("use `col='#FF000088'` for the lines() function")
KEYS pattern
Available since 1.0.0.
Time complexity: O(N) with N being the number of keys in the database, under the assumption that the key names in the database and the given pattern have limited length.
Returns all keys matching pattern.
Warning : This command is not recommended to use because it may ruin performance when it is executed against large databases instead of KEYS you can use SCAN or SETS.
Example of KEYS command to use :
redis> MSET firstname Jack lastname Stuntman age 35
"OK"
redis> KEYS *name*
1) "lastname"
2) "firstname"
redis> KEYS a??
1) "age"
redis> KEYS *
1) "lastname"
2) "age"
3) "firstname"
It is telling you that you need to close the Scanner you instantiated on System.in
with Scanner.close()
. Normally every reader should be closed.
Note that if you close System.in
, you won't be able to read from it again. You may also take a look at the Console
class.
public void readShapeData() {
Console console = System.console();
double width = Double.parseDouble(console.readLine("Enter the width of the Rectangle: "));
double height = Double.parseDouble(console.readLine("Enter the height of the Rectangle: "));
...
}
Storing files in your database will lead to a huge database size. You may not like that, for development, testing, backups, etc.
Instead, you'd use FileStream (SQL-Server) or BFILE (Oracle).
There is no default-implementation of BFILE/FileStream in Postgres, but you can add it: https://github.com/darold/external_file
And further information (in french) can be obtained here:
http://blog.dalibo.com/2015/01/26/Extension_BFILE_pour_PostgreSQL.html

This code will help you, and it's fairly self-explanatory:
#include <stdio.h> /* Standard Library of Input and Output */
#include <complex.h> /* Standard Library of Complex Numbers */
int main() {
double complex z1 = 1.0 + 3.0 * I;
double complex z2 = 1.0 - 4.0 * I;
printf("Working with complex numbers:\n\v");
printf("Starting values: Z1 = %.2f + %.2fi\tZ2 = %.2f %+.2fi\n", creal(z1), cimag(z1), creal(z2), cimag(z2));
double complex sum = z1 + z2;
printf("The sum: Z1 + Z2 = %.2f %+.2fi\n", creal(sum), cimag(sum));
double complex difference = z1 - z2;
printf("The difference: Z1 - Z2 = %.2f %+.2fi\n", creal(difference), cimag(difference));
double complex product = z1 * z2;
printf("The product: Z1 x Z2 = %.2f %+.2fi\n", creal(product), cimag(product));
double complex quotient = z1 / z2;
printf("The quotient: Z1 / Z2 = %.2f %+.2fi\n", creal(quotient), cimag(quotient));
double complex conjugate = conj(z1);
printf("The conjugate of Z1 = %.2f %+.2fi\n", creal(conjugate), cimag(conjugate));
return 0;
}
with:
creal(z1)
: get the real part (for float crealf(z1)
, for long double creall(z1)
)
cimag(z1)
: get the imaginary part (for float cimagf(z1)
, for long double cimagl(z1)
)
Another important point to remember when working with complex numbers is that functions like cos()
, exp()
and sqrt()
must be replaced with their complex forms, e.g. ccos()
, cexp()
, csqrt()
.
select * from yourtable
where created < now()
and created > concat(curdate(),' 4:30:00 AM')
setting aria-hidden to false and toggling it on element.show() worked for me.
e.g
<span aria-hidden="true">aria text</span>
$(span).attr('aria-hidden', 'false');
$(span).show();
and when hiding back
$(span).attr('aria-hidden', 'true');
$(span).hide();
Quite a painful problem for me too. Just spent about an hour trying to build and re-build - no joy. In the end I had to do this:
I guess it's a bunch of jargon about arm6 , arm7 as it looked like my project was valid for both, at least the settings seemed to say so ) , my guess is this is a cynical way to bamboozle us with the technicalities, which we don't understand, so we just take the easy option and target the latest iOS ( good for Apple with more people being up-to-date ) ....
Short answer: use time.clock() for timing in Python.
On *nix systems, clock() returns the processor time as a floating point number, expressed in seconds. On Windows, it returns the seconds elapsed since the first call to this function, as a floating point number.
time() returns the the seconds since the epoch, in UTC, as a floating point number. There is no guarantee that you will get a better precision that 1 second (even though time() returns a floating point number). Also note that if the system clock has been set back between two calls to this function, the second function call will return a lower value.
try this
$tz = new DateTimeZone('Your Time Zone');
$date = new DateTime($today,$tz);
$interval = new DateInterval('P1D');

This question is protected, which I understand. However, I do not see an answer here, what I see is a lot of people showing what they came up with from having the same question.
There are currently five Regional Internet Registries with varying degrees of functionality that serve as the first point of contact with regard to IP ownership. The process is in flux, which is why the various services here work sometimes and don't at other times.
Who Is is (obviously) an ancient TCP protocol, however -- the way it worked originally was by connection to port 43, which makes it problematic getting it routed through leased connections, through firewalls...etc.
At this moment -- most Who Is is done via RESTful HTTP and ARIN, RIPE and APNIC have RESTful services that work. LACNIC's returns a 503 and AfriNIC apparently has no such API. (All have online services, however.)
That will get you -- the address of the IP's registered owner, but -- not your client's location -- you must get that from them and also -- you have to ask for it. Also, proxies are the least of your worries when validating the IP that you think is the originator.
People do not appreciate the notion that they are being tracked, so -- my thoughts are -- get it from your client directly and with their permission and expect a lot to balk at the notion.
That is called a shebang, it tells the shell what program to interpret the script with, when executed.
In your example, the script is to be interpreted and run by the bash shell.
Some other example shebangs are:
(From Wikipedia)
#!/bin/sh — Execute the file using sh, the Bourne shell, or a compatible shell
#!/bin/csh — Execute the file using csh, the C shell, or a compatible shell
#!/usr/bin/perl -T — Execute using Perl with the option for taint checks
#!/usr/bin/php — Execute the file using the PHP command line interpreter
#!/usr/bin/python -O — Execute using Python with optimizations to code
#!/usr/bin/ruby — Execute using Ruby
and a few additional ones I can think off the top of my head, such as:
#!/bin/ksh
#!/bin/awk
#!/bin/expect
In a script with the bash shebang, for example, you would write your code with bash syntax; whereas in a script with expect shebang, you would code it in expect syntax, and so on.
Response to updated portion:
It depends on what /bin/sh
actually points to on your system. Often it is just a symlink to /bin/bash
. Sometimes portable scripts are written with #!/bin/sh
just to signify that it's a shell script, but it uses whichever shell is referred to by /bin/sh
on that particular system (maybe it points to /bin/bash
, /bin/ksh
or /bin/zsh
)

I think @ben-rollert's solution is a good solution.
You just have to be careful if you want to use this solution in a function inside a new package.
When developping packages, it's recommended to use the syntaxe packagename::function_name()
(see http://kbroman.org/pkg_primer/pages/depends.html).
In this case, you have to use the version of as.Date()
defined by the zoo
library.
Here is an example :

> as.Date(zoo::as.yearmon("1989-10", "%Y-%m"))
Error in as.Date.default(zoo::as.yearmon("1989-10", "%Y-%m")) :
do not know how to convert 'zoo::as.yearmon("1989-10", "%Y-%m")' to class “Date”
> zoo::as.Date(zoo::as.yearmon("1989-10", "%Y-%m"))
[1] "1989-10-01"
So if you're developping a package, the good practice is to use :
zoo::as.Date(zoo::as.yearmon("1989-10", "%Y-%m"))
If the child takes the full width of the container excluding scrollbar (the default), then you can subtract the widths:
var child = document.querySelector(".somethingBig");
var scrollbarWidth = child.parentNode.offsetWidth - child.offsetWidth;
PROBLEM :-
Sometimes, Localhost may not get resolved. So it tends to return an output as seen below :

SOLUTION :-
Guess, this error is most probably returned by Local Squid deployed in the server.
So, it worked fine and good after replacing localhost by the local_ip in which the ElasticSearch has been deployed.
Another way...
This is nice if you can't remember the regex or don't care to look it up. But the regex mentioned by others is a nice solution as well.
You should always avoid using system()
because
You should use CreateProcess().
You can use Createprocess() to just start up an .exe and creating a new process for it. The application will run independent from the calling application.
Here's an example I used in one of my projects:
#include <windows.h>
VOID startup(LPCTSTR lpApplicationName)
{
// additional information
STARTUPINFO si;
PROCESS_INFORMATION pi;
// set the size of the structures
ZeroMemory( &si, sizeof(si) );
si.cb = sizeof(si);
ZeroMemory( &pi, sizeof(pi) );
// start the program up
CreateProcess( lpApplicationName, // the path
argv[1], // Command line
NULL, // Process handle not inheritable
NULL, // Thread handle not inheritable
FALSE, // Set handle inheritance to FALSE
0, // No creation flags
NULL, // Use parent's environment block
NULL, // Use parent's starting directory
&si, // Pointer to STARTUPINFO structure
&pi // Pointer to PROCESS_INFORMATION structure (removed extra parentheses)
);
// Close process and thread handles.
CloseHandle( pi.hProcess );
CloseHandle( pi.hThread );
}
EDIT: The error you are getting is because you need to specify the path of the .exe file not just the name. Openfile.exe probably doesn't exist.
for same height you should chage your css "display" Properties. For more detail see given example.

In the new release of dplyr
(0.6.0
awaiting in April 2017), we can also do an assignment (:=
) and pass variables as column names by unquoting (!!
) to not evaluate it
library(dplyr)
multipetalN <- function(df, n){
varname <- paste0("petal.", n)
df %>%
mutate(!!varname := Petal.Width * n)
}
data(iris)
iris1 <- tbl_df(iris)
iris2 <- tbl_df(iris)
for(i in 2:5) {
iris2 <- multipetalN(df=iris2, n=i)
}
Checking the output based on @MrFlick's multipetal
applied on 'iris1'
identical(iris1, iris2)
#[1] TRUE
If you need to log an error to Apache error log you can try this:
error_log( print_r($multidimensionalarray, TRUE) );
If you're using Bootstrap try this:
<div class="row">
<div class="col" style="text-align:left">left align</div>
<div class="col" style="text-align:right">right align</div>
</div>
FYI you can sometimes use SYSTEM or Trustedinstaller to kill tasks ;)
google quickkill_3_0.bat
sc config TrustedInstaller binPath= "cmd /c TASKKILL /F /IM notepad.exe
sc start "TrustedInstaller"
The query either returned no rows or is erroneus, thus FALSE
is returned. Change it to
if (!$dbc || mysqli_num_rows($dbc) == 0)
mysqli_num_rows
:
Return Values
Returns TRUE on success or FALSE on failure. For SELECT, SHOW, DESCRIBE or EXPLAIN mysqli_query() will return a result object.
You can always do:
... ng-model="file.PLIK_STATUS" ng-change="file.PLIK_STATUS = setFileStatus(file.PLIK_ID,file.PLIK_STATUS,'{{file.PLIK_STATUS}}')" ...
and in controller:
$scope.setFileStatus = function (plik_id, new_status, old_status) {
var answer = confirm('Czy na pewno zmienic status dla pliku ?');
if (answer) {
podasysService.setFileStatus(plik_id, new_status).then(function (result) {
return new_status;
});
}else{
return old_status;
}
};
I have encountered this problem and i solved mentioned problem by adding -DprofileIdEnabled=true
parameter while running mvn cli command.
Please run your mvn cli command as : mvn clean install -Pdev1 -DprofileIdEnabled=true
.
In addition to this solution, you don't need to remove activeByDefault settings in your POM mentioned as previouses answer.
I hope this answer solve your problem.
For those doing video I cobbled the following based on @tsh :
import cv2 as cv
import numpy as np
def nothing(x):pass
cap = cv.VideoCapture(0)
cv.namedWindow('videoUI', cv.WINDOW_NORMAL)
cv.createTrackbar('T','videoUI',0,255,nothing)
while(True):
ret, frame = cap.read()
vid_gray = cv.cvtColor(frame, cv.COLOR_BGR2GRAY)
thresh = cv.getTrackbarPos('T','videoUI');
vid_bw = cv.threshold(vid_gray, thresh, 255, cv.THRESH_BINARY)[1]
cv.imshow('videoUI',cv.flip(vid_bw,1))
if cv.waitKey(1) & 0xFF == ord('q'):
break
cap.release()
cv.destroyAllWindows()
Results in:
Because you can't easily union a function definition and another data type, I find having these types around useful to strongly type them. Based on Drew's answer.
type Func<TArgs extends any[], TResult> = (...args: TArgs) => TResult;
//Syntax sugar
type Action<TArgs extends any[]> = Func<TArgs, undefined>;
Now you can strongly type every parameter and the return type! Here's an example with more parameters than what is above.
save(callback: Func<[string, Object, boolean], number>): number
{
let str = "";
let obj = {};
let bool = true;
let result: number = callback(str, obj, bool);
return result;
}
Now you can write a union type, like an object or a function returning an object, without creating a brand new type that may need to be exported or consumed.
//THIS DOESN'T WORK
let myVar1: boolean | (parameters: object) => boolean;
//This works, but requires a type be defined each time
type myBoolFunc = (parameters: object) => boolean;
let myVar1: boolean | myBoolFunc;
//This works, with a generic type that can be used anywhere
let myVar2: boolean | Func<[object], boolean>;
PHP sends headers automatically if set up to use internal encoding:
ini_set('default_charset', 'utf-8');
I can't add a comment yet, so I wanted to share that HTTP_REFERER is not always sent.
You can get the user's WindowsIdentity object under Windows Authentication by:
WindowsIdentity identity = HttpContext.Current.Request.LogonUserIdentity;
and then you can get the information about the user like identity.Name.
Please note you need to have HttpContext for these code.
Try the following steps:
I assume that you haven't set the TableName
property of the DataTable, for example via constructor:
var tbl = new DataTable("dtImage");
If you don't provide a name, it will be automatically created with "Table1"
, the next table will get "Table2"
and so on.
Then the solution would be to provide the TableName
and then check with Contains(nameOfTable)
.
To clarify it: You'll get an ArgumentException
if that DataTable already belongs to the DataSet (the same reference). You'll get a DuplicateNameException
if there's already a DataTable in the DataSet with the same name(not case-sensitive).
Assert allows you to assert a condition (post or pre) applies in your code. It's a way of documenting your intentions and having the debugger inform you with a dialog if your intention is not met.
Unlike a breakpoint, the Assert goes with your code and can be used to add additional detail about your intention.
it works for me, just change: Provider=Microsoft.Jet.OLEDB.4.0 (VS2013)
OleDbConnection connection = new OleDbConnection(
"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=Z:\\GENERAL\\OFMPTP_PD_SG.MDB");
DataSet DS = new DataSet();
connection.Open();
string query =
@"SELECT * from MONTHLYPROD";
OleDbDataAdapter DBAdapter = new OleDbDataAdapter();
DBAdapter.SelectCommand = new OleDbCommand(query, connection);
DBAdapter.Fill(DS);

Seems like as this thread says a breaking change was issued:
Components can no longer be imported through "@angular/material". Use the individual secondary entry-points, such as @angular/material/button.
Update: can confirm, this was the issue. After downgrading @angular/[email protected]...
to @angular/[email protected]
we could solve this temporarily. Guess we need to update the project for a long term solution.
I like leoj3n's solution. It can also be used to set a relative "start in" directory, which is what I needed by using start's /D parameter. Without /c or /k in as an argument to cmd, the subsequent start command doesn't run. /c will close the shell immediately after running the command and /k will keep it open (even after the command is done). So if whatever you're running spits to standard out and you need to see it, use /k.
Unfortunately, according to the lnk file specification, the icon is not saved in the shortcut, but rather "encoded using environment variables, which makes it possible to find the icon across machines where the locations vary but are expressed using environment variables." So it's likely that if paths are changing and you're trying to take the icon from the executable you're pointing to, it won't transfer correctly.
we should use name value pair binding values into dropdown.see the code for more details
function myCtrl($scope) {_x000D_
$scope.statusTaskList = [_x000D_
{ name: 'Open', value: '1' },_x000D_
{ name: 'In Progress', value: '2' },_x000D_
{ name: 'Complete', value: '3' },_x000D_
{ name: 'Deleted', value: '4' },_x000D_
];_x000D_
$scope.atcStatusTasks = $scope.statusTaskList[0]; // 0 -> Open _x000D_
}
_x000D_
<select ng-model="atcStatusTasks" ng-options="s.name for s in statusTaskList"></select>

It looks like not all of your prerequisites are really working as they should be. Also, you'll want to make sure that you are installing from the console itself and not through any kind of remote session at all. (I know, this is a pain in the a@@, but sometimes it makes a difference.)
You can acess the SQL Server 2005 Books Online on the Web at: http://msdn.microsoft.com/en-us/library/ms130214(SQL.90).aspx. This documentation should help you decipher the logs.
Bonus tidbit: Once you get that far, if you plan on installing SP2 without getting an installation that fails and rolls back, another little pearl of wisdom is described here: http://blog.andreloker.de/post/2008/07/17/SQL-Server-hotfix-KB948109-fails-with-error-1920.aspx. (My issue was that the "SQL Server VSS Writer" (Service) was not even installed.) Good luck!
If you've already assigned the variables using the npm module dotenv
, then they should show up in your global variables. That module is here.
While running the debugger, go to your variables tab (right click to reopen if not visible) and then open "global" and then "process." There should then be an env section...
Hold on...
From my experience, you SHOULD make sure that the DocumCompleted
belongs to YOUR URL and not to a frame sub-page, script, image, CSS, etc. And that is regardless of the IsBusy
or the ReadyState
is finished or not, which both are often inaccurate when page is slightly complex.
Well, that is my own personal experience, on a working program of VB.2013 and IE11. Let me also mention that you should take into account also the compatibility mode IE7 which is ON by default at the webBrowser1
.
' Page, sub-frame or resource was totally loaded.
Private Sub webBrowser1_DocumentCompleted(sender As Object, _
e As WebBrowserDocumentCompletedEventArgs) _
Handles webBrowser1.DocumentCompleted
' Check if finally the full page was loaded (inc. sub-frames, javascripts, etc)
If e.Url.ToString = webBrowser1.Url.ToString Then
' Only now you are sure!
fullyLoaded = True
End If
End Sub

If you want to get the root directory of your yii2 project use, assuming that the name of your project is project_app you'll need to use:
echo Yii::getAlias('@app');
on windows you'd see "C:\dir\to\project_app"
on linux you'll get "/var/www/dir/to/your/project_app"
I was formally using:

Well, I understand this question is Visual Studio GUI related, but maybe the asker can try this trick also. Just giving a different perspective in solving this problem.
I like to use terminal a lot for GIT, so here are the simple steps:
Pre-requisites...
Now,
Don't create any file inside the repository. Keep it empty. Copy its URL. It should be something like https://github.com/Username/ProjectName.git
Open up the terminal and redirect to your Visual Studio Project directory
Configure your credentials
git config --global user.name "your_git_username"
git config --global user.email "your_git_email"
Then type these commands
git init
git add .
git commit -m "First Migration Commit"
git remote add origin paste_your_URL_here
git push -u origin master
Done...Hope this helps
You should probably stop using launch images in iOS 8 and use a storyboard or nib/xib.
In Xcode 6, open the File
menu and choose New
? File...
? iOS
? User Interface
? Launch Screen
.
Then open the settings for your project by clicking on it.
In the General
tab, in the section called App Icons and Launch Images
, set the Launch Screen File
to the files you just created (this will set UILaunchStoryboardName
in info.plist
).
Note that for the time being the simulator will only show a black screen, so you need to test on a real device.

You can use the WooCommerce Layered Nav widget, which allows you to use different sets of attributes as filters for products. Here's the "official" description:
Shows a custom attribute in a widget which lets you narrow down the list of products when viewing product categories.
If you look into plugins/woocommerce/widgets/widget-layered_nav.php, you can see the way it operates with the attributes in order to set filters. The URL then looks like this:
... and the digits are actually the id-s of the different attribute values, that you want to set.

Your submit button doesn't have a name. Add name="submit" to your submit button.
If you view source on the form in the browser, you'll see how it submits to self - the form's action attribute will contain the name of the current script - therefore when the form submits, it submits to itself. Edit for vanity sake!

(Note: it is not libs
and this is not a mistake). It should be in the same structure it should be in the APK
file.
In my case it was:
Project:
|--lib:
|--|--armeabi:
|--|--|--.so files.
So I've made a lib folder and inside it an armeabi folder where I've inserted all the needed .so files. I then zipped the folder into a .zip
(the structure inside the zip file is now lib/armeabi/*.so) I renamed the .zip
file into armeabi.jar
and added the line compile fileTree(dir: 'libs', include: '*.jar')
into dependencies {}
in the gradle's build file.
This solved my problem in a rather clean way.
I had the same issue
It was resolved by checking the http.proxy value in git config (mine was incorrect and unwanted), Hence I removed http.proxy value from git config
commands:
List down the config items in the file
git config --list
Remove the proxy
git config --global --unset http.proxy
The problem was solved!
I had the same problem on macOS 10.14.5 using Xcode 10.2.1. After none of the solution here worked for me I restarted the Mac and this did the trick...
For me, this was related to the scenario described by Smi, with the difference being that vcvarsall.bat
itself was failing due to an invalid path.
This was cause by line-breaks within the path, which meant vcvarsall.bat
couldn't find the common tools directory for some reason.
For completeness, I would add that, if you wanted to copy an entire directory full of controlled AND uncontrolled files, you could use the following:
git mv old new
git checkout HEAD old
The uncontrolled files will be copied over, so you should clean them up:
git clean -fdx new
You can't. This is an intentional design decision by the Git maintainers. Basically, the purpose of a Source Code Management System like Git is managing source code and empty directories aren't source code. Git is also often described as a content tracker, and again, empty directories aren't content (quite the opposite, actually), so they are not tracked.
If one's find
does not have -mmin
and if one also is stuck with a find
that accepts only integer values for -mtime
, then all is not necessarily lost if one considers that "older than" is similar to "not newer than".
If we were able to create a file that that has an mtime of our cut-off time, we can ask find
to locate the files that are "not newer than" our reference file.
To create a file that has the correct time stamp is a bit involved because a system that doesn't have an adequate find
probably also has a less-than-capable date
command that could do things like: date +%Y%m%d%H%M%S -d "6 hours ago"
.
Fortunately, other old tools that can manage this, albeit in a more unwieldy way.
Consider that six hours is 21600 seconds. We want to find the time that is six hours ago in a format that is useful:
$ date && perl -e '@d=localtime time()-21600; \
printf "%4d%02d%02d%02d%02d.%02d\n", $d[5]+1900,$d[4]+1,$d[3],$d[2],$d[1],$d[0]'
> Thu Apr 16 04:50:57 CDT 2020
202004152250.57
The perl statement did produce a useful date, but it has to be put to better use:
$ date && touch -t `perl -e '@d=localtime time()-21600; \
printf "%4d%02d%02d%02d%02d.%02d\n", \
$d[5]+1900,$d[4]+1,$d[3],$d[2],$d[1],$d[0]'` ref_file && ls -l ref_file
Thu Apr 16 04:53:54 CDT 2020
-rw-rw-rw- 1 root sys 0 Apr 15 22:53 ref_file
Now the solution for this old UNIX is something along the lines of:
$ find . -type f ! -newer ref_file -a ! -name ref_file -exec rm -f "{}" \;
It might also be a good idea to clean up our reference file...
$ rm -f ref_file
None of the other answers were working for me. I ended up creating a function within my iframe that returns the object I was looking for:
function getElementWithinIframe() {
return document.getElementById('copy-sheet-form');
}
Then you call that function like so to retrieve the element:
var el = document.getElementById("iframeId").contentWindow.functionNameToCall();
I tested Github Flavored Markdown for a while and can summarize with four rules:
-
For example, if your section is named this:
## 1.1 Hello World
Create a link to it this way:
[Link](#11-hello-world)
First you check your user agent OS Linux or windows or another. Then Your OS Windows Then this code use:
public function win_os(){
ob_start();
system('ipconfig-a');
$mycom=ob_get_contents(); // Capture the output into a variable
ob_clean(); // Clean (erase) the output buffer
$findme = "Physical";
$pmac = strpos($mycom, $findme); // Find the position of Physical text
$mac=substr($mycom,($pmac+36),17); // Get Physical Address
return $mac;
}
And your OS Linux Ubuntu or Linux then this code use:
public function unix_os(){
ob_start();
system('ifconfig -a');
$mycom = ob_get_contents(); // Capture the output into a variable
ob_clean(); // Clean (erase) the output buffer
$findme = "Physical";
//Find the position of Physical text
$pmac = strpos($mycom, $findme);
$mac = substr($mycom, ($pmac + 37), 18);
return $mac;
}
This code may be work OS X.

This answer will cover most of the scenario. I can across this situation when user try to copy paste the phone number
$('#help_number').keyup(function(){
$(this).val().match(/\d+/g).join("")
});
Explanation:
str= "34%^gd 5-67 6-6ds"
str.match(/\d+/g)
It will give a array of string as output >> ["34", "56766"]
str.match(/\d+/g).join("")
join will convert and concatenate that array data into single string
output >> "3456766"
In my example I need the output as 209-356-6788 so I used replace
$('#help_number').keyup(function(){
$(this).val($(this).val().match(/\d+/g).join("").replace(/(\d{3})\-?(\d{3})\-?(\d{4})/,'$1-$2-$3'))
});
Execute dump query in terminal then it will work
mysql -u root -p <Database_Name> > <path of the input file>

I just wanted to bring a small contribution, because I have been able to debug on my Nexus 5 device on Windows 8, without doing all of this.
When I plugged it, there wasn't any yellow exclamation mark within Device Manager. So for me, the drivers were OK. But the device was not listed within my Eclipse DDMS. After a little bit of searching, it was just an option to change in the device settings. By default, the Nexus 5 USB computer connection is in MTP mode (Media Device).

No DBMS I know of has any "optimization" that will make a VARCHAR
with a 2^n
length perform better than one with a max
length that is not a power of 2.
I think early SQL Server versions actually treated a VARCHAR
with length 255 differently than one with a higher maximum length. I don't know if this is still the case.
For almost all DBMS, the actual storage that is required is only determined by the number of characters you put into it, not the max
length you define. So from a storage point of view (and most probably a performance one as well), it does not make any difference whether you declare a column as VARCHAR(100)
or VARCHAR(500)
.
You should see the max
length provided for a VARCHAR
column as a kind of constraint (or business rule) rather than a technical/physical thing.
For PostgreSQL the best setup is to use text
without a length restriction and a CHECK CONSTRAINT
that limits the number of characters to whatever your business requires.
If that requirement changes, altering the check constraint is much faster than altering the table (because the table does not need to be re-written)
The same can be applied for Oracle and others - in Oracle it would be VARCHAR(4000)
instead of text
though.
I don't know if there is a physical storage difference between VARCHAR(max)
and e.g. VARCHAR(500)
in SQL Server. But apparently there is a performance impact when using varchar(max)
as compared to varchar(8000)
.
See this link (posted by Erwin Brandstetter as a comment)
Edit 2013-09-22
Regarding bigown's comment:
In Postgres versions before 9.2 (which was not available when I wrote the initial answer) a change to the column definition did rewrite the whole table, see e.g. here. Since 9.2 this is no longer the case and a quick test confirmed that increasing the column size for a table with 1.2 million rows indeed only took 0.5 seconds.
For Oracle this seems to be true as well, judging by the time it takes to alter a big table's varchar
column. But I could not find any reference for that.
For MySQL the manual says "In most cases, ALTER TABLE
makes a temporary copy of the original table". And my own tests confirm that: running an ALTER TABLE
on a table with 1.2 million rows (the same as in my test with Postgres) to increase the size of a column took 1.5 minutes. In MySQL however you can not use the "workaround" to use a check constraint to limit the number of characters in a column.
For SQL Server I could not find a clear statement on this but the execution time to increase the size of a varchar
column (again the 1.2 million rows table from above) indicates that no rewrite takes place.
Edit 2017-01-24
Seems I was (at least partially) wrong about SQL Server. See this answer from Aaron Bertrand that shows that the declared length of a nvarchar
or varchar
columns makes a huge difference for the performance.
Here is my code to rename multiple files in a folder successfully:
public static void renameAllFilesInFolder(String folderPath, String newName, String extension) {
if(newName == null || newName.equals("")) {
System.out.println("New name cannot be null or empty");
return;
}
if(extension == null || extension.equals("")) {
System.out.println("Extension cannot be null or empty");
return;
}
File dir = new File(folderPath);
int i = 1;
if (dir.isDirectory()) { // make sure it's a directory
for (final File f : dir.listFiles()) {
try {
File newfile = new File(folderPath + "\\" + newName + "_" + i + "." + extension);
if(f.renameTo(newfile)){
System.out.println("Rename succesful: " + newName + "_" + i + "." + extension);
} else {
System.out.println("Rename failed");
}
i++;
} catch (Exception e) {
e.printStackTrace();
}
}
}
}
and run it for an example:
renameAllFilesInFolder("E:\\Downloads\\Foldername", "my_avatar", "gif");
Direct to remove the '\n' from the fgets output if every line has '\n'
line[strlen(line) - 1] = '\0';
Otherwise:
void remove_newline_ch(char *line)
{
int new_line = strlen(line) -1;
if (line[new_line] == '\n')
line[new_line] = '\0';
}
You want the :checkbox:checked
selector and map
to create an array of the values:
var checkedValues = $('input:checkbox:checked').map(function() {
return this.value;
}).get();
If your checkboxes have a shared class it would be faster to use that instead, eg. $('.mycheckboxes:checked')
, or for a common name $('input[name="Foo"]:checked')
- Update -
If you don't need IE support then you can now make the map()
call more succinct by using an arrow function:
var checkedValues = $('input:checkbox:checked').map((i, el) => el.value).get();
I like the solution of Hans-Peter Störr... But I think it is not quite correct. Sadly containsInAnyOrder
does not accept a Collection
of objetcs to compare to. So it has to be a Collection
of Matcher
s:
assertThat(set1, containsInAnyOrder(set2.stream().map(IsEqual::equalTo).collect(toList())))
The import are:
import static java.util.stream.Collectors.toList;
import static org.hamcrest.Matchers.containsInAnyOrder;
import static org.junit.Assert.assertThat;
I'm pretty sure you either have to use .lower() or use a regular expression. I'm not aware of a built-in case-insensitive string comparison function.
Instead of using a ServletContextListener, use a HttpSessionListener
.
In the sessionCreated()
method, you can set the session timeout programmatically:
public class MyHttpSessionListener implements HttpSessionListener {
public void sessionCreated(HttpSessionEvent event){
event.getSession().setMaxInactiveInterval(15 * 60); // in seconds
}
public void sessionDestroyed(HttpSessionEvent event) {}
}
And don't forget to define the listener in the deployment descriptor:
<webapp>
...
<listener>
<listener-class>com.example.MyHttpSessionListener</listener-class>
</listener>
</webapp>
(or since Servlet version 3.0 you can use @WebListener
annotation instead).
Still, I would recommend creating different web.xml files for each application and defining the session timeout there:
<webapp>
...
<session-config>
<session-timeout>15</session-timeout> <!-- in minutes -->
</session-config>
</webapp>
This is just because the application is built in non unicode language fonts and you are running the system on unicode fonts. change your default non unicode fonts to arabic by going in regional settings advanced tab in control panel. That will solve your problem.
I have recently migrated from C3P0
to HikariCP
in a Spring and Hibernate based project and it was not as easy as I had imagined and here I am sharing my findings.
For Spring Boot
see my answer here
I have the following setup
Some of the below configs are similar to some of the answers above but, there are differences.
In order to pull in the right jars, I needed to pull in the following jars
//latest driver because *brettw* see https://github.com/pgjdbc/pgjdbc/pull/849
compile 'org.postgresql:postgresql:42.2.0'
compile('com.zaxxer:HikariCP:2.7.6') {
//they are pulled in separately elsewhere
exclude group: 'org.hibernate', module: 'hibernate-core'
}
// Recommended to use HikariCPConnectionProvider by Hibernate in 4.3.6+
compile('org.hibernate:hibernate-hikaricp:4.3.8.Final') {
//they are pulled in separately elsewhere, to avoid version conflicts
exclude group: 'org.hibernate', module: 'hibernate-core'
exclude group: 'com.zaxxer', module: 'HikariCP'
}
// Needed for HikariCP logging if you use log4j
compile('org.slf4j:slf4j-simple:1.7.25')
compile('org.slf4j:slf4j-log4j12:1.7.25') {
//log4j pulled in separately, exclude to avoid version conflict
exclude group: 'log4j', module: 'log4j'
}
In order to get Spring & Hibernate to make use of Hikari Connection pool, you need to define the HikariDataSource
and feed it into sessionFactory
bean as shown below.
<!-- HikariCP Database bean -->
<bean id="dataSource" class="com.zaxxer.hikari.HikariDataSource" destroy-method="close">
<constructor-arg ref="hikariConfig" />
</bean>
<!-- HikariConfig config that is fed to above dataSource -->
<bean id="hikariConfig" class="com.zaxxer.hikari.HikariConfig">
<property name="poolName" value="SpringHikariPool" />
<property name="dataSourceClassName" value="org.postgresql.ds.PGSimpleDataSource" />
<property name="maximumPoolSize" value="20" />
<property name="idleTimeout" value="30000" />
<property name="dataSourceProperties">
<props>
<prop key="serverName">localhost</prop>
<prop key="portNumber">5432</prop>
<prop key="databaseName">dbname</prop>
<prop key="user">dbuser</prop>
<prop key="password">dbpassword</prop>
</props>
</property>
</bean>
<bean class="org.springframework.orm.hibernate4.LocalSessionFactoryBean" id="sessionFactory">
<!-- Your Hikari dataSource below -->
<property name="dataSource" ref="dataSource"/>
<!-- your other configs go here -->
<property name="hibernateProperties">
<props>
<prop key="hibernate.connection.provider_class">org.hibernate.hikaricp.internal.HikariCPConnectionProvider</prop>
<!-- Remaining props goes here -->
</props>
</property>
</bean>
Once the above are setup then, you need to add an entry to your log4j or logback
and set the level
to DEBUG
to see Hikari
Connection Pool start up.
<!-- Keep additivity=false to avoid duplicate lines -->
<logger additivity="false" name="com.zaxxer.hikari">
<level value="debug"/>
<!-- Your appenders goes here -->
</logger>
Via application.properties
in Spring Boot
debug=true
logging.level.com.zaxxer.hikari.HikariConfig=DEBUG
Using logback.xml
<logger name="com.zaxxer.hikari" level="DEBUG" additivity="false">
<appender-ref ref="STDOUT" />
</logger>
With the above you should be all good to go! Obviously you need to customize the HikariCP
pool configs in order to get the performance that it promises.
@Martijn your order of function calls is slightly off. Try this instead:
x=-3:0.1:3;
y = x.^3;
plot(x,y), hold on
plot([-3 3], [0 0], 'k:')
hold off
Try this, It worked for me
SELECT * FROM (
SELECT
[Code],
[Name],
[CategoryCode],
[CreatedDate],
[ModifiedDate],
[CreatedBy],
[ModifiedBy],
[IsActive],
ROW_NUMBER() OVER(PARTITION BY [Code],[Name],[CategoryCode] ORDER BY ID DESC) rownumber
FROM MasterTable
) a
WHERE rownumber = 1
When you use ANNs, you rarely know about the internals of the systems you want to learn. Some things cannot be learned without a bias. E.g., have a look at the following data: (0, 1), (1, 1), (2, 1), basically a function that maps any x to 1.
If you have a one layered network (or a linear mapping), you cannot find a solution. However, if you have a bias it's trivial!
In an ideal setting, a bias could also map all points to the mean of the target points and let the hidden neurons model the differences from that point.
No, that's the correct way to do it. This worked exactly as it should, something you can work from perhaps:
using System;
class Program {
static void Main(string[] args) {
System.AppDomain.CurrentDomain.UnhandledException += UnhandledExceptionTrapper;
throw new Exception("Kaboom");
}
static void UnhandledExceptionTrapper(object sender, UnhandledExceptionEventArgs e) {
Console.WriteLine(e.ExceptionObject.ToString());
Console.WriteLine("Press Enter to continue");
Console.ReadLine();
Environment.Exit(1);
}
}
Do keep in mind that you cannot catch type and file load exceptions generated by the jitter this way. They happen before your Main() method starts running. Catching those requires delaying the jitter, move the risky code into another method and apply the [MethodImpl(MethodImplOptions.NoInlining)] attribute to it.
And by the way for you fellow googlers for selecting multiple folders in the search input you separate your directories with a comma. Works both for exclude and include
Example: ./src/public/,src/components/
If two beans are dependent on each other then we should not use Constructor injection in both the bean definitions. Instead we have to use setter injection in any one of the beans. (of course we can use setter injection n both the bean definitions, but constructor injections in both throw 'BeanCurrentlyInCreationException'
Refer Spring doc at "https://docs.spring.io/spring/docs/current/spring-framework-reference/core.html#resources-resource"
From NumberKeyListener source code. This method they use to check if char is contained in defined array of accepted characters:
protected static boolean ok(char[] accept, char c) {
for (int i = accept.length - 1; i >= 0; i--) {
if (accept[i] == c) {
return true;
}
}
return false;
}
It is similar to @ÓscarLópez solution. Might be a bit faster cause of absence of foreach iterator.
Real simple. You just need to have the string 'selected' added to the right option. In the following code, ${myBean.foo == val ? 'selected' : ' '} will add the string 'selected' if the option's value is the same as the bean value;
<select name="foo" id="foo" value="${myBean.foo}">
<option value="">ALL</option>
<c:forEach items="${fooList}" var="val">
<option value="${val}" ${myBean.foo == val ? 'selected' : ' '}><c:out value="${val}" ></c:out></option>
</c:forEach>
</select>
The difference can be illustrated by the following:
std::cout << std::endl;
is equivalent to
std::cout << '\n' << std::flush;
So,
std::endl
If you want to force an immediate flush to the output.\n
if you are worried about performance (which is probably not the case if you are using the <<
operator).I use \n
on most lines.
Then use std::endl
at the end of a paragraph (but that is just a habit and not usually necessary).
Contrary to other claims, the \n
character is mapped to the correct platform end of line sequence only if the stream is going to a file (std::cin
and std::cout
being special but still files (or file-like)).
Yes, it can throw an exception and you can declare that in the signature of the constructor too as shown in the example below:
public class ConstructorTest
{
public ConstructorTest() throws InterruptedException
{
System.out.println("Preparing object....");
Thread.sleep(1000);
System.out.println("Object ready");
}
public static void main(String ... args)
{
try
{
ConstructorTest test = new ConstructorTest();
}
catch (InterruptedException e)
{
System.out.println("Got interrupted...");
}
}
}
for IE9 I found that a meta tag was required to set the mode
<meta http-equiv="X-UA-Compatible" content="IE=Edge"/>
<video width="400" height="300" preload controls>
<source src="movie.mp4" type="video/mp4" />
Your browser does not support the video tag
</video>
These are subplot grid parameters encoded as a single integer. For example, "111" means "1x1 grid, first subplot" and "234" means "2x3 grid, 4th subplot".
Alternative form for add_subplot(111)
is add_subplot(1, 1, 1)
.
I'll give a slightly advanced answer. In Python, functions are first-class objects. This means they can be "dynamically created, destroyed, passed to a function, returned as a value, and have all the rights as other variables in the programming language have."
Calling a function/class instance in Python means invoking the __call__
method of that object. For old-style classes, class instances are also callable but only if the object which creates them has a __call__
method. The same applies for new-style classes, except there is no notion of "instance" with new-style classes. Rather they are "types" and "objects".
As quoted from the Python 2 Data Model page, for function objects, class instances(old style classes), and class objects(new-style classes), "x(arg1, arg2, ...)
is a shorthand for x.__call__(arg1, arg2, ...)
".
Thus whenever you define a function with the shorthand def funcname(parameters):
you are really just creating an object with a method __call__
and the shorthand for __call__
is to just name the instance and follow it with parentheses containing the arguments to the call. Because functions are first class objects in Python, they can be created on the fly with dynamic parameters (and thus accept dynamic arguments). This comes into handy with decorator functions/classes which you will read about later.
For now I suggest reading the Official Python Tutorial.
return or return false are not the same as continue. If the loop is inside a function the remainder of the function will not execute as you would expect with a true "continue".
If you are on Ubuntu you don't need to write any other code except your Python file's code , Here are the Steps :-
You can manually place a check in your code. Like this -
if result != []:
for face in result:
bounding_box = face['box']
x, y, w, h = bounding_box[0], bounding_box[1], bounding_box[2], bounding_box[3]
rect_face = cv2.rectangle(frame, (x, y), (x+w, y+h), (46, 204, 113), 2)
face = rgb[y:y+h, x:x+w]
#CHECK FACE SIZE (EXIST OR NOT)
if face.shape[0]*face.shape[1] > 0:
predicted_name, class_probability = face_recognition(face)
print("Result: ", predicted_name, class_probability)

Update your project level build.gradle to latest version - it works for me
classpath 'com.android.tools.build:gradle:3.2.1'
classpath 'com.google.gms:google-services:4.2.0'
This one works on Bootstrap 4.3.1.

All of the answers above are correct; attr_reader
and attr_writer
are more convenient to write than manually typing the methods they are shorthands for. Apart from that they offer much better performance than writing the method definition yourself. For more info see slide 152 onwards from this talk (PDF) by Aaron Patterson.
Use regular expression to achieve this task. Please refer the below code.
public static void main(String[] args) {
try {
BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
System.out.print("Enter your content: ");
String data = reader.readLine();
boolean b1 = Pattern.matches("^\\d+$", data);
boolean b2 = Pattern.matches("[0-9a-zA-Z([+-]?\\d*\\.+\\d*)]*", data);
boolean b3 = Pattern.matches("^([+-]?\\d*\\.+\\d*)$", data);
if(b1) {
System.out.println("It is integer.");
} else if(b2) {
System.out.println("It is String. ");
} else if(b3) {
System.out.println("It is Float. ");
}
} catch (IOException ex) {
Logger.getLogger(TypeOF.class.getName()).log(Level.SEVERE, null, ex);
}
}
Swift 5.0
let titleAttrString = NSMutableAttributedString(string: "This is a title", attributes: [NSAttributedString.Key.font: UIFont(name: "CustomFontName", size: 17) as Any])
let messageAttrString = NSMutableAttributedString(string: "This is a message", attributes: [NSAttributedString.Key.font: UIFont(name: "CustomFontName", size: 13) as Any])
alertController.setValue(titleAttrString, forKey: "attributedTitle")
alertController.setValue(messageAttrString, forKey: "attributedMessage")
'''my file name is
"0_male_0.wav", "0_male_2.wav"... "0_male_30.wav"...
"1_male_0.wav", "1_male_2.wav"... "1_male_30.wav"...
"8_male_0.wav", "8_male_2.wav"... "8_male_30.wav"
when I wav.read(files) I want to read them in a sorted torder, i.e., "0_male_0.wav"
"0_male_1.wav"
"0_male_2.wav" ...
"0_male_30.wav"
"1_male_0.wav"
"1_male_1.wav"
"1_male_2.wav" ...
"1_male_30.wav"
so this is how I did it.
Just take all files start with "0_*" as an example. Others you can just put it in a loop
'''
import scipy.io.wavfile as wav
import glob
from os.path import isfile, join
#get all the file names in file_names. THe order is totally messed up
file_names = [f for f in listdir(audio_folder_dir) if isfile(join(audio_folder_dir, f)) and '.wav' in f]
#find files that belongs to "0_*" group
filegroup0 = glob.glob(audio_folder_dir+'/0_*')
#now you get sorted files in group '0_*' by the last number in the filename
filegroup0 = sorted(filegroup0, key=getKey)
def getKey(filename):
file_text_name = os.path.splitext(os.path.basename(filename)) #you get the file's text name without extension
file_last_num = os.path.basename(file_text_name[0]).split('_') #you get three elements, the last one is the number. You want to sort it by this number
return int(file_last_num[2])
That's how I did my particular case. Hope it's helpful.
Woff is a compressed (zipped) form of the TrueType - OpenType font. It is small and can be delivered over the network like a graphic file. Most importantly, this way the font is preserved completely including rendering rule tables that very few people care about because they use only Latin script.
Take a look at [dead URL removed]. The font you see is an experimental web delivered smartfont (woff) that has thousands of combined characters making complex shapes. The underlying text is simple Latin code of romanized Singhala. (Copy and paste to Notepad and see).
Only woff can do this because nobody has this font and yet it is seen anywhere (Mac, Win, Linux and even on smartphones by all browsers except by IE. IE does not have full support for Open Types).
An abstract class is a class that contains at least one abstract method, which is a method without any actual code in it, just the name and the parameters, and that has been marked as "abstract".
The purpose of this is to provide a kind of template to inherit from and to force the inheriting class to implement the abstract methods.
An abstract class thus is something between a regular class and a pure interface. Also interfaces are a special case of abstract classes where ALL methods are abstract.
See this section of the PHP manual for further reference.
Google recommend that you don't use any of them, source.
There is no need to use entity references like
&mdash
,&rdquo
, or☺
, assuming the same encoding (UTF-8) is used for files and editors as well as among teams.
Is there a reason you can't simply use "
?
Write as
<input type="submit" ng-click="profileForm.$valid==true?updateMyProfile():''" name="submit" value="Save" class="submit" id="submit">
The PerlMonks and PerlDoc links from cartman and Olafur are a great reference - below is my crack at a summary:
my
variables are lexically scoped within a single block defined by {}
or within the same file if not in {}
s. They are not accessible from packages/subroutines defined outside of the same lexical scope / block.
our
variables are scoped within a package/file and accessible from any code that use
or require
that package/file - name conflicts are resolved between packages by prepending the appropriate namespace.
Just to round it out, local
variables are "dynamically" scoped, differing from my
variables in that they are also accessible from subroutines called within the same block.
Use Glide library instead of directly loading into imageview
Glide : https://github.com/bumptech/glide
Glide.with(this).load(Uri.parse(filelocation))).into(img_selectPassportPic);
Use the built-in function dir()
.
A good idea is to set all of the "" (blank cells) to NA before any further analysis.
If you are reading your input from a file, it is a good choice to cast all "" to NAs:
foo <- read.table(file="Your_file.txt", na.strings=c("", "NA"), sep="\t") # if your file is tab delimited
If you have already your table loaded, you can act as follows:
foo[foo==""] <- NA
Then to keep only rows with no NA you may just use na.omit()
:
foo <- na.omit(foo)
Or to keep columns with no NA:
foo <- foo[, colSums(is.na(foo)) == 0]
As you can see in the reference sources, NameValueCollection inherits from NameObjectCollectionBase.
So you take the base-type, get the private hashtable via reflection, and check if it contains a specific key.
For it to work in Mono as well, you need to see what the name of the hashtable is in mono, which is something you can see here (m_ItemsContainer), and get the mono-field, if the initial FieldInfo is null (mono-runtime).
Like this
public static class ParameterExtensions
{
private static System.Reflection.FieldInfo InitFieldInfo()
{
System.Type t = typeof(System.Collections.Specialized.NameObjectCollectionBase);
System.Reflection.FieldInfo fi = t.GetField("_entriesTable", System.Reflection.BindingFlags.Instance | System.Reflection.BindingFlags.NonPublic);
if(fi == null) // Mono
fi = t.GetField("m_ItemsContainer", System.Reflection.BindingFlags.Instance | System.Reflection.BindingFlags.NonPublic);
return fi;
}
private static System.Reflection.FieldInfo m_fi = InitFieldInfo();
public static bool Contains(this System.Collections.Specialized.NameValueCollection nvc, string key)
{
//System.Collections.Specialized.NameValueCollection nvc = new System.Collections.Specialized.NameValueCollection();
//nvc.Add("hello", "world");
//nvc.Add("test", "case");
// The Hashtable is case-INsensitive
System.Collections.Hashtable ent = (System.Collections.Hashtable)m_fi.GetValue(nvc);
return ent.ContainsKey(key);
}
}
for ultra-pure non-reflective .NET 2.0 code, you can loop over the keys, instead of using the hash-table, but that is slow.
private static bool ContainsKey(System.Collections.Specialized.NameValueCollection nvc, string key)
{
foreach (string str in nvc.AllKeys)
{
if (System.StringComparer.InvariantCultureIgnoreCase.Equals(str, key))
return true;
}
return false;
}
As of version 0.8.9, Android Studio supports the Maven Central Repository by default. So to add an external maven dependency all you need to do is edit the module's build.gradle file and insert a line into the dependencies section like this:
dependencies {
// Remote binary dependency
compile 'net.schmizz:sshj:0.10.0'
}
You will see a message appear like 'Sync now...' - click it and wait for the maven repo to be downloaded along with all of its dependencies. There will be some messages in the status bar at the bottom telling you what's happening regarding the download. After it finishes this, the imported JAR file along with its dependencies will be listed in the External Repositories tree in the Project Browser window, as shown below.
Some further explanations here: http://developer.android.com/sdk/installing/studio-build.html
As c69 mentioned there is no way to do it with pure CSS.
but you can use HTML instead:
use
<head>
<base target="_blank">
</head>
in your HTML <head>
tag for making all of page links which not include target
attribute to be opened in a new blank window by default.
otherwise you can set target attribute for each link like this:
<a href="/yourlink.html" target="_blank">test-link</a>
and it will override
<head>
<base target="_blank">
</head>
tag if it was defined previously.
The docs give a fair indicator of what's required., however requests
allow us to skip a few steps:
You only need to install the security
package extras (thanks @admdrew for pointing it out)
$ pip install requests[security]
or, install them directly:
$ pip install pyopenssl ndg-httpsclient pyasn1
Requests will then automatically inject pyopenssl
into urllib3
If you're on ubuntu, you may run into trouble installing pyopenssl
, you'll need these dependencies:
$ apt-get install libffi-dev libssl-dev
Using double
to store large integers is dubious; the largest integer that can be stored reliably in double
is much smaller than DBL_MAX
. You should use long long
, and if that's not enough, you need your own arbitrary-precision code or an existing library.
To see details about the latest available tag I sometimes use:
git show `git describe` --pretty=fuller
I have tried with following code. it's working for me fine
ManageOrder Order = new ManageOrder();
Organization.DataSource = Order.getAllOrganization(Session["userID"].ToString());
Organization.DataValueField = "OrganisationID";
Organization.DataTextField = "OrganisationName";
Organization.DataBind();
Organization.Items.Insert(0, new ListItem("Select Organisation", "0"));
You can always take a look at the .size
attribute. It is defined as an integer, and is zero (0
) when there are no elements in the array:
import numpy as np
a = np.array([])
if a.size == 0:
# Do something when `a` is empty
You can use a WScript
object and call the Sleep
method on it:
Set WScript = CreateObject("WScript.Shell")
WScript.Sleep 2000 'Sleeps for 2 seconds
Another option is to import and use the WinAPI function directly (only works in VBA, thanks @Helen):
Declare Sub Sleep Lib "kernel32" (ByVal dwMilliseconds As Long)
Sleep 2000
Check out the language reference:
http://msdn.microsoft.com/en-us/library/aa195811(office.11).aspx
expression.Open(FileName, UpdateLinks, ReadOnly, Format, Password, WriteResPassword, IgnoreReadOnlyRecommended, Origin, Delimiter, Editable, Notify, Converter, AddToMru, Local, CorruptLoad)
The only solution I have found is not to set the index to a previous frame and wait (then OpenCV stops reading frames, anyway), but to initialize the capture one more time. So, it looks like this:
cap = cv2.VideoCapture(camera_url)
while True:
ret, frame = cap.read()
if not ret:
cap = cv.VideoCapture(camera_url)
continue
# do your processing here
And it works perfectly!
