You need to have everything in the hpp file. The problem is that the classes aren't actually created until the compiler sees that they're needed by some OTHER cpp file - so it has to have all the code available to compile the templated class at that time.
One thing that I tend to do is to try to split my templates into a generic non-templated part (which can be split between cpp/hpp) and the type-specific template part which inherits the non-templated class.
Just look in file /var/log/auth.log on the server. Setting additional verbosity with -vv on the client side won't help, because the server is unlikely to offer too much information to a possible attacker.
I'm guessing that you don't need to re-increment the existing data so, why can't you just run a simple ALTER TABLE command to change the PK's attributes?
Something like:
ALTER TABLE `content` CHANGE `id` `id` SMALLINT( 5 ) UNSIGNED NOT NULL AUTO_INCREMENT
I've tested this code on my own MySQL database and it works but I have not tried it with any meaningful number of records. Once you've altered the row then you need to reset the increment to a number guaranteed not to interfere with any other records.
ALTER TABLE `content` auto_increment = MAX(`id`) + 1
Again, untested but I believe it will work.
Try this:
DECLARE @sql NVARCHAR(MAX) = N'';
SELECT @sql += N'DROP PROCEDURE dbo.'
+ QUOTENAME(name) + ';
' FROM sys.procedures
WHERE name LIKE N'spname%'
AND SCHEMA_NAME(schema_id) = N'dbo';
EXEC sp_executesql @sql;
In order to see the changes that have been staged already, you can pass the -–staged
option to git diff
(in pre-1.6 versions of Git, use –-cached
).
git diff --staged
git diff --cached
I you are using jQuery you can put the checkboxes in a form and then use something like this:
var formData = jQuery("#" + formId).serialize();
$.ajax({
type: "POST",
url: url,
data: formData,
success: success
});
I have used this code to implement dark mode...it worked fine for me...You can use it in a switch on....listener...
//setting up Night Mode...
AppCompatDelegate.setDefaultNightMode(AppCompatDelegate.MODE_NIGHT_YES);
//Store current mode in a sharedprefernce to retrieve on restarting app
editor.putBoolean("NightMode", true);
editor.apply();
//restart all the activities to apply changed mode...
TaskStackBuilder.create(getActivity())
.addNextIntent(new Intent(getActivity(), MainActivity.class))
.addNextIntent(getActivity().getIntent())
.startActivities();
The following approach will sort the list in descending order and also handles the 'null' values, just in case if you have any null values then Collections.sort() will throw NullPointerException
Collections.sort(list, new Comparator<Long>() {
public int compare(Long o1, Long o2) {
return o1==null?Integer.MAX_VALUE:o2==null?Integer.MIN_VALUE:o2.compareTo(o1);
}
});
You have to be a little careful with using kdiff3
as while git mergetool
can be configured to save a .orig
file during merging, the default behaviour for kdiff3
is to also save a .orig
backup file independently of git mergetool
.
You have to make sure that mergetool
backup is off:
git config --global mergetool.keepBackup false
and also that kdiff3's settings are set to not create a backup:
Configure/Options => Directory Merge => Backup Files (*.orig)
Expat is pretty decent. It's hard to give good recommendations without more information though.
In setting.py
in MIDDLEWARE you can simply remove/comment this line:
'django.middleware.csrf.CsrfViewMiddleware',
var a = A.parentNode.replaceChild(document.createElement("span"), A);
a is the replaced A element.
I had a similar issue, I was getting 400, Bad Request only with the PUT, where as POST request was perfectly fine.
Below code worked fine for POST but was giving BAD Request for PUT:
conn.setRequestProperty("Content-Type", "application/json");
os.writeBytes(json);
After making below changes worked fine for both POST and PUT
conn.setRequestProperty("Content-Type", "application/json; charset=UTF-8");
os.write(json.getBytes("UTF-8"));
You can use regular grep like this:
tail -f admin.log | grep -v "Nopaging the limit is\|keyword to remove is"
The difference between 'exec' and 'system' is that exec replaces your current program with 'command' and NEVER returns to your program. system, on the other hand, forks and runs 'command' and returns you the exit status of 'command' when it is done running. The back tick runs 'command' and then returns a string representing its standard out (whatever it would have printed to the screen)
You can also use popen to run shell commands and I think that there is a shell module - 'use shell' that gives you transparent access to typical shell commands.
Hope that clarifies it for you.

How To Launch App From url w/o Extra Click If you prefer a solution that does not include the interim step of clicking a link, the following can be used. With this javascript, I was able to return a Httpresponse object from Django/Python that successfully launches an app if it is installed or alternatively launches the app store in the case of a time out. Note I also needed to adjust the timeout period from 500 to 100 in order for this to work on an iPhone 4S. Test and tweak to get it right for your situation.

When you don't have a PC on hand, you could use Eruda, which is devtools for mobile browsers https://github.com/liriliri/eruda
It is provided as embeddable javascript and also a bookmarklet (pasting bookmarklet in chrome removes the javascript: prefix, so you have to type it yourself)
You need to use setLayoutManager
in the RecyclerView#onCreate()
method. Before adding recyclerView
to a view, it must have the LayoutManager
set.
private RecyclerView menuAsList;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_home);
menuAsList = (RecyclerView) findViewById(R.id.recyclerView_mainMenu);
menuAsList.setLayoutManager(new LinearLayoutManager(Home.this));
}
Mark, this is already answered in your previous topic. But OK, here it is again:
Suppose ${list}
points to a List<Object>
, then the following
<c:forEach items="${list}" var="item">
${item}<br>
</c:forEach>
does basically the same as as following in "normal Java":
for (Object item : list) {
System.out.println(item);
}
If you have a List<Map<K, V>>
instead, then the following
<c:forEach items="${list}" var="map">
<c:forEach items="${map}" var="entry">
${entry.key}<br>
${entry.value}<br>
</c:forEach>
</c:forEach>
does basically the same as as following in "normal Java":
for (Map<K, V> map : list) {
for (Entry<K, V> entry : map.entrySet()) {
System.out.println(entry.getKey());
System.out.println(entry.getValue());
}
}
The key
and value
are here not special methods or so. They are actually getter methods of Map.Entry
object (click at the blue Map.Entry
link to see the API doc). In EL (Expression Language) you can use the .
dot operator to access getter methods using "property name" (the getter method name without the get
prefix), all just according the Javabean specification.
That said, you really need to cleanup the "answers" in your previous topic as they adds noise to the question. Also read the comments I posted in your "answers".
I ran into this issue recently and figured out a cheeky way of doing it without stringing together additional IN clauses
You could make use of Tuples
SELECT field1, field2, field3
FROM table1
WHERE (1, name) IN ((1, value1), (1, value2), (1, value3),.....(1, value5000));
Oracle does allow >1000 Tuples but not simple values. More on this here,
https://community.oracle.com/message/3515498#3515498
and
https://community.oracle.com/thread/958612
This is of course if you don't have the option of using a subquery inside IN to get the values you need from a temp table.
2017 update
The original answer below assumes that the OP wants to include non-empty text node and other node types as well as elements. It doesn't seem clear to me now from the question whether this is a valid assumption.
Assuming instead you just want the element index, previousElementSibling
is now well-supported (which was not the case in 2012) and is the obvious choice now. The following (which is the same as some other answers here) will work in everything major except IE <= 8.
function getElementIndex(node) {
var index = 0;
while ( (node = node.previousElementSibling) ) {
index++;
}
return index;
}
Original answer
Just use previousSibling
until you hit null
. I'm assuming you want to ignore white space-only text nodes; if you want to filter other nodes then adjust accordingly.
function getNodeIndex(node) {
var index = 0;
while ( (node = node.previousSibling) ) {
if (node.nodeType != 3 || !/^\s*$/.test(node.data)) {
index++;
}
}
return index;
}
The below trick worked for me.
1) Comment/delete the below configuration from server.xml file (inside conf folder) of tomcat.
2) Delete the existing ROOT folder (If any) residing inside tomcat webapps folder. And rename your war (e.g: test.war ) file to ROOT.war.
Remember that while renaming war file to ROOT.war "ROOT" should be in caps.
Limitation: You can deploy only one application inside one tomcat instance.
Indeed a one-hot encoder will work just fine here, convert any string and numerical categorical variables you want into 1's and 0's this way and random forest should not complain.
iCalendar was based on a vCalendar and Outlook 2007 handles both formats well so it doesn't really matters which one you choose.
I'm not sure if this stands for Outlook 2003. I guess you should give it a try.
Outlook's default calendar format is iCalendar (*.ics
)
If you use $window.localStorage.setItem(key,value)
to store,$window.localStorage.getItem(key)
to retrieve and $window.localStorage.removeItem(key)
to remove, then you can access the values in any page.
You have to pass the $window
service to the controller. Though in JavaScript, window
object is available globally.
By using $window.localStorage.xxXX()
the user has control over the localStorage
value. The size of the data depends upon the browser. If you only use $localStorage
then value remains as long as you use window.location.href to navigate to other page and if you use <a href="location"></a>
to navigate to other page then your $localStorage
value is lost in the next page.
ListView
returns collections of selected items and indices through the SelectedItems
and SelectedIndices
properties. Note that these collections are empty, if no item is currently selected (lst.SelectedItems.Count = 0
). The first item that is selected is lst.SelectedItems(0)
. The index of this item in the Items
collection is lst.SelectedIndices(0)
. So basically
lst.SelectedItems(0)
is the same as
lst.Items(lst.SelectedIndices(0))
You can also use check boxes. Set CheckBoxes
to True
for this. Through the CheckedItems
and CheckedIndices
properties you can see which items are checked.
We don't know what server.properties file is that, we neither know what SimocoPoolSize means (do you?)
Let's guess you are using some custom pool of database connections. Then, I guess the problem is that your pool is configured to open 100 or 120 connections, but you Postgresql server is configured to accept MaxConnections=90
. These seem conflictive settings. Try increasing MaxConnections=120
.
But you should first understand your db layer infrastructure, know what pool are you using, if you really need so many open connections in the pool. And, specially, if you are gracefully returning the opened connections to the pool
A digit in the range 1-9 followed by zero or more other digits:
^[1-9]\d*$
To allow numbers with an optional decimal point followed by digits. A digit in the range 1-9 followed by zero or more other digits then optionally followed by a decimal point followed by at least 1 digit:
^[1-9]\d*(\.\d+)?$
Notes:
The ^
and $
anchor to the start and end basically saying that the whole string must match the pattern
()?
matches 0 or 1 of the whole thing between the brackets
Update to handle commas:
In regular expressions .
has a special meaning - match any single character. To match literally a .
in a string you need to escape the .
using \.
This is the meaning of the \.
in the regexp above. So if you want to use comma instead the pattern is simply:
^[1-9]\d*(,\d+)?$
Further update to handle commas and full stops
If you want to allow a . between groups of digits and a , between the integral and the fractional parts then try:
^[1-9]\d{0,2}(\.\d{3})*(,\d+)?$
i.e. this is a digit in the range 1-9 followed by up to 2 other digits then zero or more groups of a full stop followed by 3 digits then optionally your comma and digits as before.
If you want to allow a . anywhere between the digits then try:
^[1-9][\.\d]*(,\d+)?$
i.e. a digit 1-9 followed by zero or more digits or full stops optionally followed by a comma and one or more digits.
For bootstrap 4 this works for me.

next
- it's like return
, but for blocks! (So you can use this in any proc
/lambda
too.)
That means you can also say next n
to "return" n
from the block. For instance:
puts [1, 2, 3].map do |e|
next 42 if e == 2
e
end.inject(&:+)
This will yield 46
.
Note that return
always returns from the closest def
, and never a block; if there's no surrounding def
, return
ing is an error.
Using return
from within a block intentionally can be confusing. For instance:
def my_fun
[1, 2, 3].map do |e|
return "Hello." if e == 2
e
end
end
my_fun
will result in "Hello."
, not [1, "Hello.", 2]
, because the return
keyword pertains to the outer def
, not the inner block.
If you want to declare the dictionary once and never change it then declare it as readonly:
private static readonly Dictionary<string, string> ErrorCodes
= new Dictionary<string, string>
{
{ "1", "Error One" },
{ "2", "Error Two" }
};
If you want to dictionary items to be readonly (not just the reference but also the items in the collection) then you will have to create a readonly dictionary class that implements IDictionary.
Check out ReadOnlyCollection for reference.
BTW const can only be used when declaring scalar values inline.
It is cumbersome to interoperate socket.io and connect sessions support. The problem is not because socket.io "hijacks" request somehow, but because certain socket.io transports (I think flashsockets) don't support cookies. I could be wrong with cookies, but my approach is the following:
Possible solutions:
Use nginx on the server as a proxy that will listen to port A and multiplex to port B or C.
If you use AWS you can use the load balancer to redirect the request to specific port based on the host.
Correct way to remove install plug-in from Eclipse/STS :
Go to install folder of eclipse ----> plugin --> select required plugin and remove it.
Ex-
Step 1.
E:\springsource\sts-3.4.0.RELEASE\plugins
Step 2.
select and remove related plugins jars.

Here's a Boolean thing:
if (not suffix == "flac" ) or (not suffix == "cue" ): # WRONG! FAILS
print filename + ' is not a flac or cue file'
but
if not (suffix == "flac" or suffix == "cue" ): # CORRECT!
print filename + ' is not a flac or cue file'
(not a) or (not b) == not ( a and b )
,
is false only if a and b are both true
not (a or b)
is true only if a and be are both false.
If you don't have a .gitignore file. You can create a new one by
touch .gitignore
And you can exclude a folder by entering the below command in the .gitignore file
/folderName
push this file into your git repository so that when a new person clone your project he don't have to add the same again
Personally, I prefer changing the method signature to:
public ResponseEntity<?>
This gives the advantage of possibly returning an error message as single item for services which, when ok, return a list of items.
When returning I don't use any type (which is unused in this case anyway):
return new ResponseEntity<>(entities, HttpStatus.OK);
That would only happen if PostCode
is missing a space.
You could add conditionality such that all of PostCode
is retrieved should a space not be found as follows
select SUBSTRING(PostCode, 1 ,
case when CHARINDEX(' ', PostCode ) = 0 then LEN(PostCode)
else CHARINDEX(' ', PostCode) -1 end)

Here is the detailed answer to the question:
Pass data into the HTTP header from the Angular side (Please note I am using Angular4.0+ in the application).
There is more than one way we can pass data into the headers. The syntax is different but all means the same.
// Option 1
const httpOptions = {
headers: new HttpHeaders({
'Authorization': 'my-auth-token',
'ID': emp.UserID,
})
};
// Option 2
let httpHeaders = new HttpHeaders();
httpHeaders = httpHeaders.append('Authorization', 'my-auth-token');
httpHeaders = httpHeaders.append('ID', '001');
httpHeaders.set('Content-Type', 'application/json');
let options = {headers:httpHeaders};
// Option 1
return this.http.post(this.url + 'testMethod', body,httpOptions)
// Option 2
return this.http.post(this.url + 'testMethod', body,options)
In the call you can find the field passed as a header as shown in the image below :
Still, if you are facing the issues like.. (You may need to change the backend/WebAPI side)
Response to preflight request doesn't pass access control check: No ''Access-Control-Allow-Origin'' header is present on the requested resource. Origin ''http://localhost:4200'' is therefore not allowed access
Response for preflight does not have HTTP ok status.

This is how I solved it. I forgot that sublist was a direct reference to the elements in the original list, so it makes sense why it wouldn't work.
ArrayList<Integer> inputA = new ArrayList<Integer>(input.subList(0, input.size()/2));
A simple question should be followed by a short, simple and clear answer.
When we are getting a value of the property it fires its get{}
part.
When we are setting a value to the property it fires its set{}
part.
PS. When setting a value to the property, SWIFT automatically creates a constant named "newValue" = a value we are setting. After a constant "newValue" becomes accessible in the property's set{}
part.
Example:
var A:Int = 0
var B:Int = 0
var C:Int {
get {return 1}
set {print("Recived new value", newValue, " and stored into 'B' ")
B = newValue
}
}
//When we are getting a value of C it fires get{} part of C property
A = C
A //Now A = 1
//When we are setting a value to C it fires set{} part of C property
C = 2
B //Now B = 2
I got the exact path using:
netstat -ln | grep -o -m 1 -E '\S*mysqld?\.sock'
Since this only returns the path and doesn't require any input you could potentially use it in a shell script.
MySQL must be currently running on your machine for this to work. Works for MariaDB too.
Usually if you use space as delimiter, you want to treat multiple spaces as one, because you parse the output of a command aligning some columns with spaces. (and the google search for that lead me here)
In this case a single cut
command is not sufficient, and you need to use:
tr -s ' ' | cut -d ' ' -f 2
Or
awk '{print $2}'
Regarding your first question.The pipe works as follows:
numberValue | number: {minIntegerDigits}.{minFractionDigits}-{maxFractionDigits}
minFractionDigits: Minimum number of integer digits to show after the decimal point
maxFractionDigits: Maximum number of integer digits to show after the decimal point
2.Regarding your second question, Filter to zero decimal places as follows:
{{ numberValue | number: '1.0-0' }}

Actually, the section from where you took that code offers an explanation as well:
To move n discs from peg A to peg C:
- move n-1 discs from A to B. This leaves disc #n alone on peg A
- move disc #n from A to C
- move n-1 discs from B to C so they sit on disc #n
It's pretty clear that you first have to remove n - 1 discs to get access to the nth one. And that you have to move them first to another peg than where you want the full tower to appear.
The code in your post has three arguments, besides the number of discs: A source peg, a destination peg and a temporary peg on which discs can be stored in between (where every disc with size n - 1 fits).
The recursion happens actually twice, there, once before the writeln
, once after. The one before the writeln
will move n - 1 discs onto the temporary peg, using the destination peg as temporary storage (the arguments in the recursive call are in different order). After that, the remaining disc will be moved to the destination peg and afterwards the second recursion compeltes the moving of the entire tower, by moving the n - 1 tower from the temp peg to the destination peg, above disc n.
Here is a simple routine for an array of primitive elements:
for ($i = 0; $i < count($mySimpleArray); $i++)
{
echo $mySimpleArray[$i] . "\n";
}
If your PHP app is holding open many SQL Server connections, then, as you may know, you have a problem with your app's database code. It should be releasing/disposing those connections after use and using connection pooling. Have a look here for a decent article on the topic...

You should put in WEB-INF any pages, or pieces of pages, that you do not want to be public. Usually, JSP or facelets are found outside WEB-INF, but in this case they are easily accesssible for any user. In case you have some authorization restrictions, WEB-INF can be used for that.
WEB-INF/lib can contain 3rd party libraries which you do not want to pack at system level (JARs can be available for all the applications running on your server), but only for this particular applciation.
Generally speaking, many configurations files also go into WEB-INF.
As for WEB-INF/classes - it exists in any web-app, because that is the folder where all the compiled sources are placed (not JARS, but compiled .java files that you wrote yourself).
Just for giggles, give this XAML a whirl. It isn't perfect as it is not an 'alignment' but it allows you to adjust text alignment within a paragraph.
<TextBlock>
<TextBlock BaselineOffset="30">One</TextBlock>
<TextBlock BaselineOffset="20">Two</TextBlock>
<Run>Three</Run>
<Run BaselineAlignment="Subscript">Four</Run>

You get the index number of the row in the datagridview using northwind database employees tables as an example:
using System;
using System.Windows.Forms;
namespace WindowsFormsApplication5
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
// TODO: This line of code loads data into the 'nORTHWNDDataSet.Employees' table. You can move, or remove it, as needed.
this.employeesTableAdapter.Fill(this.nORTHWNDDataSet.Employees);
}
private void dataGridView1_CellDoubleClick(object sender, DataGridViewCellEventArgs e)
{
var dataIndexNo = dataGridView1.Rows[e.RowIndex].Index.ToString();
string cellValue = dataGridView1.Rows[e.RowIndex].Cells[1].Value.ToString();
MessageBox.Show("The row index = " + dataIndexNo.ToString() + " and the row data in second column is: "
+ cellValue.ToString());
}
}
}
the result will show you index number of record and the contents of the second table column in datagridview:
$scope.rtGo = function(){
$window.sessionStorage.removeItem('message');
$window.sessionStorage.removeItem('status');
}
This might be completely off base, but can't you just copy the whole column into a new spreadsheet and then sort the column? I'm assuming that you don't need to maintain the order integrity.
I have the same issue in [email protected]
, and it because the extra slash in the end of regex route:
.when('/goods/publish/:classId/', option)
to
.when('/goods/publish/:classId', option)
and it works correctly.
In Jupyter Notebook,
SHIFT+ TAB(to move left) and TAB(to move right) movement is perfectly working.
EDIT: In summary, back in 2010 when this question was asked the most common way to solve this problem was to save a reference to the context where the setTimeout
function call is made, because setTimeout
executes the function with this
pointing to the global object:
var that = this;
if (this.options.destroyOnHide) {
setTimeout(function(){ that.tip.destroy() }, 1000);
}
In the ES5 spec, just released a year before that time, it introduced the bind
method, this wasn't suggested in the original answer because it wasn't yet widely supported and you needed polyfills to use it but now it's everywhere:
if (this.options.destroyOnHide) {
setTimeout(function(){ this.tip.destroy() }.bind(this), 1000);
}
The bind
function creates a new function with the this
value pre-filled.
Now in modern JS, this is exactly the problem arrow functions solve in ES6:
if (this.options.destroyOnHide) {
setTimeout(() => { this.tip.destroy() }, 1000);
}
Arrow functions do not have a this
value of its own, when you access it, you are accessing the this
value of the enclosing lexical scope.
HTML5 also standardized timers back in 2011, and you can pass now arguments to the callback function:
if (this.options.destroyOnHide) {
setTimeout(function(that){ that.tip.destroy() }, 1000, this);
}

I am using microsoft's Android emulator with Android Studio. I have an AMD FX8350. The ARM one in android studio is terribly slow.
The only issue is that it requires Hyper-V which is not available on windows 10 Home.
Its a really quick emulator and it is free. The best emulator I have used.
Prior to PHP 5.5, the the PHP docs used to say:
empty() only checks variables as anything else will result in a parse error
In PHP < 5.5 you weren't able use empty()
directly on a function's return value. Instead, you could assign the return from getError()
to a variable and run empty()
on the variable.
In PHP >= 5.5 this is no longer necessary.

There could be several things causing this and it somewhat depends on what you have set up in your database.
First, you could be using a PK in the table that is also an FK to another table making the relationship 1-1. IN this case you may need to do an update rather than an insert. If you really can have only one address record for an order this may be what is happening.
Next you could be using some sort of manual process to determine the id ahead of time. The trouble with those manual processes is that they can create race conditions where two records gab the same last id and increment it by one and then the second one can;t insert.
Third, you query as it is sent to the database may be creating two records. To determine if this is the case, Run Profiler to see exactly what SQL code you are sending and if ti is a select instead of a values clause, then run the select and see if you have due to the joins gotten some records to be duplicated. IN any even when you are creating code on the fly like this the first troubleshooting step is ALWAYS to run Profiler and see if what got sent was what you expected to be sent.

If you already have the full local copy, you can remove unwanted sub folders by using --set-depth
command.
svn update --set-depth=exclude www
See: http://blogs.collab.net/subversion/sparse-directories-now-with-exclusion
The set-depth
command support multipile paths.
Updating the root local copy will not change the depth of the modified folder.
To restore the folder to being recusively checkingout, you could use --set-depth
again with infinity param.
svn update --set-depth=infinity www
You can create a temp table variable and insert the data into it, then insert the data into your actual table by selecting it from the temp table.

Datanewolf's code is ALMOST right. I had to reverse both the winding and the normals to make it work properly with the fixed pipeline. The below works correctly with cull on or off for me:
std::vector<GLfloat> vertices;
std::vector<GLfloat> normals;
std::vector<GLfloat> texcoords;
std::vector<GLushort> indices;
float const R = 1./(float)(rings-1);
float const S = 1./(float)(sectors-1);
int r, s;
vertices.resize(rings * sectors * 3);
normals.resize(rings * sectors * 3);
texcoords.resize(rings * sectors * 2);
std::vector<GLfloat>::iterator v = vertices.begin();
std::vector<GLfloat>::iterator n = normals.begin();
std::vector<GLfloat>::iterator t = texcoords.begin();
for(r = 0; r < rings; r++) for(s = 0; s < sectors; s++) {
float const y = sin( -M_PI_2 + M_PI * r * R );
float const x = cos(2*M_PI * s * S) * sin( M_PI * r * R );
float const z = sin(2*M_PI * s * S) * sin( M_PI * r * R );
*t++ = s*S;
*t++ = r*R;
*v++ = x * radius;
*v++ = y * radius;
*v++ = z * radius;
*n++ = -x;
*n++ = -y;
*n++ = -z;
}
indices.resize(rings * sectors * 4);
std::vector<GLushort>::iterator i = indices.begin();
for(r = 0; r < rings-1; r++)
for(s = 0; s < sectors-1; s++) {
/*
*i++ = r * sectors + s;
*i++ = r * sectors + (s+1);
*i++ = (r+1) * sectors + (s+1);
*i++ = (r+1) * sectors + s;
*/
*i++ = (r+1) * sectors + s;
*i++ = (r+1) * sectors + (s+1);
*i++ = r * sectors + (s+1);
*i++ = r * sectors + s;
}
Edit: There was a question on how to draw this... in my code I encapsulate these values in a G3DModel class. This is my code to setup the frame, draw the model, and end it:

Improving Android Studio Performance on Memory-Constrained Machines
For t2/m3/c3/c4/r3/i2/d2 instances:
m1 small, medium, and large instances tend to perform higher than expected. c1.medium is another freak, at 800 MBit/s.
I gathered this by combing dozens of sources doing benchmarks (primarily using iPerf & TCP connections). Credit to CloudHarmony & flux7 in particular for many of the benchmarks (note that those two links go to google searches showing the numerous individual benchmarks).
The large instance size has the most variation reported:
Burstable (T2) instances appear to exhibit burstable networking performance too:
The CloudHarmony iperf benchmarks show initial transfers start at 1 GBit/s and then gradually drop to the sustained levels above after a few minutes. PDF links to reports below:
t2.small (PDF)
Note that these are within the same region - if you're transferring across regions, real performance may be much slower. Even for the larger instances, I'm seeing numbers of a few hundred MBit/s.
Open up your file using regular old vanilla Notepad that comes with Windows.
It will show you the encoding of the file when you click "Save As...".
It'll look like this:
Whatever the default-selected encoding is, that is what your current encoding is for the file.
If it is UTF-8, you can change it to ANSI and click save to change the encoding (or visa-versa).
I realize there are many different types of encoding, but this was all I needed when I was informed our export files were in UTF-8 and they required ANSI. It was a onetime export, so Notepad fit the bill for me.
FYI: From my understanding I think "Unicode" (as listed in Notepad) is a misnomer for UTF-16.
More here on Notepad's "Unicode" option: Windows 7 - UTF-8 and Unicdoe
Use a forward declaration in the header file if needed, and #import
the header files for any classes you're using in the implementation. In other words, you always #import
the files you're using in your implementation, and if you need to reference a class in your header file use a forward declaration as well.
The exception to this is that you should #import
a class or formal protocol you're inheriting from in your header file (in which case you wouldn't need to import it in the implementation).
#/bin/bash
TESTSTR="abc,def,ghij"
for i in $(echo $TESTSTR | tr ',' '\n')
do
echo $i
done
I prefer to use tr instead of sed, becouse sed have problems with special chars like \r \n in some cases.
other solution is to set IFS to certain separator
Always have handy the un-minified CSS for bootstrap so you can see what styles they have on their components, then create a CSS file AFTER it, if you don't use LESS and over-write their mixins or whatever
This is the default modal css for 768px and up:
@media (min-width: 768px) {
.modal-dialog {
width: 600px;
margin: 30px auto;
}
...
}
They have a class modal-lg
for larger widths
@media (min-width: 992px) {
.modal-lg {
width: 900px;
}
}
If you need something twice the 600px size, and something fluid, do something like this in your CSS after the Bootstrap css and assign that class to the modal-dialog.
@media (min-width: 768px) {
.modal-xl {
width: 90%;
max-width:1200px;
}
}
HTML
<div class="modal-dialog modal-xl">

$scheduled_day = date('d-m-Y', strtotime($scheduled_day))." ($days[$day])";
// provides 28-07-2018 (Sáb)

hello = "foo"
my_string = "I pity the #{hello}"
CoffeeScript actually IS javascript, but with a much better syntax.

You can think of reshaping that the new shape is filled row by row (last dimension varies fastest) from the flattened original list/array.
An easy solution is to shape the list into a (100, 28) array and then transpose it:
x = np.reshape(list_data, (100, 28)).T
Update regarding the updated example:

This confused me too, initially, because I was coming from a C background.
In C, a variable is a location in memory with a defined type. Assigning to a variable copies the data into the variable's memory location.
But in Python, variables act more like pointers to objects. So assigning one variable to another doesn't make a copy, it just makes that variable name point to the same object.

Each record from the left table will be returned as many times as there are matching records on the right table -- at least 1, but could easily be more than 1.
Try HTMLFormElement.reportValidity() where this function will invoke the input validations.

@Ahamed has a point, but if you're insisting on using lists so you can have three arraylist like this:
ArrayList<Integer> first = new ArrayList<Integer>(Arrays.AsList(100,100,100,100,100));
ArrayList<Integer> second = new ArrayList<Integer>(Arrays.AsList(50,35,25,45,65));
ArrayList<Integer> third = new ArrayList<Integer>();
for(int i = 0; i < first.size(); i++) {
third.add(first.get(i));
third.add(second.get(i));
}
Edit: If you have those values on your list that below:
List<double[]> values = new ArrayList<double[]>(2);
what you want to do is combine them, right? You can try something like this: (I assume that both array are same sized, otherwise you need to use two for statement)
ArrayList<Double> yourArray = new ArrayList<Double>();
for(int i = 0; i < values.get(0).length; i++) {
yourArray.add(values.get(0)[i]);
yourArray.add(values.get(1)[i]);
}

I nearly used everything in that article to create the SQLite database for my own C# Application.
Don't forget to download the SQLite.dll, and add it as a reference to your project. This can be done using NuGet and by adding the dll manually.
After you added the reference, refer to the dll from your code using the following line on top of your class:
using System.Data.SQLite;
You can find the dll's here:
You can find the NuGet way here:
Up next is the create script. Creating a database file:
SQLiteConnection.CreateFile("MyDatabase.sqlite");
SQLiteConnection m_dbConnection = new SQLiteConnection("Data Source=MyDatabase.sqlite;Version=3;");
m_dbConnection.Open();
string sql = "create table highscores (name varchar(20), score int)";
SQLiteCommand command = new SQLiteCommand(sql, m_dbConnection);
command.ExecuteNonQuery();
sql = "insert into highscores (name, score) values ('Me', 9001)";
command = new SQLiteCommand(sql, m_dbConnection);
command.ExecuteNonQuery();
m_dbConnection.Close();
After you created a create script in C#, I think you might want to add rollback transactions, it is safer and it will keep your database from failing, because the data will be committed at the end in one big piece as an atomic operation to the database and not in little pieces, where it could fail at 5th of 10 queries for example.
Example on how to use transactions:
using (TransactionScope tran = new TransactionScope())
{
//Insert create script here.
//Indicates that creating the SQLiteDatabase went succesfully, so the database can be committed.
tran.Complete();
}
Basically you can put HTML anywhere outside of PHP tags. It's also very beneficial to do all your necessary data processing before displaying any data, in order to separate logic and presentation.
The data display itself could be at the bottom of the same PHP file or you could include a separate PHP file consisting of mostly HTML.
I prefer this compact style:
<?php
/* do your processing here */
?>
<html>
<head>
<title><?=$title?></title>
</head>
<body>
<?php foreach ( $something as $item ) : ?>
<p><?=$item?></p>
<?php endforeach; ?>
</body>
</html>
Note: you may need to use <?php echo $var; ?>
instead of <?=$var?>
depending on your PHP setup.
This is because the original A activity is already being destroyed by the time you start it from B, C or D. Therefore, onCreate will be called in stead of onNewIntent(). One way of solving this is to always destroy the existing A(using FLAG_ACTIVITY_CLEAR_TASK | FLAG_ACTIVITY_NEW_TASK conjunction when startActivity) before starting a new A, so onCreate will always be called, and you put the code of onNewIntent() into onCreate by checking if getIntent() is the intent you started with.
Try this:
import java.net.HttpURLConnection;
URL url = new URL("http://www.myurl.com/sample.xml");
HttpURLConnection huc = (HttpURLConnection) url.openConnection();
HttpURLConnection.setFollowRedirects(false);
huc.setConnectTimeout(15 * 1000);
huc.setRequestMethod("GET");
huc.setRequestProperty("User-Agent", "Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.1.2) Gecko/20090729 Firefox/3.5.2 (.NET CLR 3.5.30729)");

An important thing to consider is that some users and some resellers (Dell) install a 64 bit VM on their 64 bit Windows, and you can't use the same SWT library on 32 bit and 64 bit VMs.
This means you will need to distribute and test different packages depending on whether users have 32-bit or a 64-bit Java VM. See this problem with Azureus, for instance, but you also have it with Eclipse, where as of today the builds on the front download page do not run on a 64 bit VM.
In addition to what Angular University said above you may want to use @Import to aggregate @Configuration classes to the other class (AuthenticationController in my case) :
@Import(SecurityConfig.class)
@RestController
public class AuthenticationController {
@Autowired
private AuthenticationManager authenticationManager;
//some logic
}

I'm using nGram, too. I use standard tokenizer and nGram just as a filter. Here is my setup:
{
"index": {
"index": "my_idx",
"type": "my_type",
"analysis": {
"index_analyzer": {
"my_index_analyzer": {
"type": "custom",
"tokenizer": "standard",
"filter": [
"lowercase",
"mynGram"
]
}
},
"search_analyzer": {
"my_search_analyzer": {
"type": "custom",
"tokenizer": "standard",
"filter": [
"standard",
"lowercase",
"mynGram"
]
}
},
"filter": {
"mynGram": {
"type": "nGram",
"min_gram": 2,
"max_gram": 50
}
}
}
}
}
Let's you find word parts up to 50 letters. Adjust the max_gram as you need. In german words can get really big, so I set it to a high value.
The Android build tools provide a debug signing mode that makes it easier for you to develop and debug your application, while still meeting the Android system requirement for signing your APK. When using debug mode to build your app, the SDK tools invoke Keytool to automatically create a debug keystore and key. This debug key is then used to automatically sign the APK, so you do not need to sign the package with your own key.
The SDK tools create the debug keystore/key with predetermined names/passwords:
Keystore name: "debug.keystore"
Keystore password: "android"
Key alias: "androiddebugkey"
Key password: "android"
CN: "CN=Android Debug,O=Android,C=US"
If necessary, you can change the location/name of the debug keystore/key or supply a custom debug keystore/key to use. However, any custom debug keystore/key must use the same keystore/key names and passwords as the default debug key (as described above). (To do so in Eclipse/ADT, go to Windows > Preferences > Android > Build.)
Caution: You cannot release your application to the public when signed with the debug certificate.

Here is a safe variant that filters out invalid ints:
List<int> ints = strings
.Select(s => Int32.TryParse(s, out int n) ? n : (int?)null)
.Where(n => n.HasValue)
.Select(n => n.Value)
.ToList();
It uses an out
variable introduced with C#7.0.
This other variant returns a list of nullable ints where null
entries are inserted for invalid ints (i.e. it preserves the original list count):
List<int?> nullableInts = strings
.Select(s => Int32.TryParse(s, out int n) ? n : (int?)null)
.ToList();
let's think in different way, what if we wanna remove a group? try this,
rm(list=ls()[grep("xxx",ls())])
I personally don't like too many tables, variables on my screen, yet I can't avoid using them. So I name the temporary things starting with "xxx", so I can remove them after it is no longer used.
Use sqlite3 database.sqlite3 < db.sql
. You'll need to make sure that your files contain valid SQL for SQLite.
I have the same problem.
I have found this solution:
Google may block sign in attempts from some apps or devices that do not use modern security standards. Since these apps and devices are easier to break into, blocking them helps keep your account safer.
Some examples of apps that do not support the latest security standards include:
Therefore, you have to enable Less Secure Sign-In (or Less secure app access) in your google account.
After sign into google account, go to:
https://www.google.com/settings/security/lesssecureapps
or
https://myaccount.google.com/lesssecureapps
In C#, you can use the following code:
using (MailMessage mail = new MailMessage())
{
mail.From = new MailAddress("[email protected]");
mail.To.Add("[email protected]");
mail.Subject = "Hello World";
mail.Body = "<h1>Hello</h1>";
mail.IsBodyHtml = true;
mail.Attachments.Add(new Attachment("C:\\file.zip"));
using (SmtpClient smtp = new SmtpClient("smtp.gmail.com", 587))
{
smtp.Credentials = new NetworkCredential("[email protected]", "password");
smtp.EnableSsl = true;
smtp.Send(mail);
}
}

As a complement of @stefano 's answer,
It is better to use command with -f
when generate a new SSH key for another account,
ssh-keygen -t rsa -f ~/.ssh/id_rsa_work -C "[email protected]"
Since id_rsa_work
file doesn't exist in path ~/.ssh/
, and I create this file manually, and it doesn't work :(
If your table has relationship with other tables using its primary or foriegen key, may be it is impossible to alter your table. so you need to drop and create the table again.
To solve these problems you need to Generate Scripts by right click on the database and in advanced option set type of data to script to scheme and data. after that, using this script with the changing your column to identify and regenerate the table using run its query.
your query will be like here:
USE [Db_YourDbName]
GO
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
Drop TABLE [dbo].[Tbl_TourTable]
CREATE TABLE [dbo].[Tbl_TourTable](
[ID] [int] IDENTITY(1,1) NOT NULL,
[Name] [nvarchar](50) NULL,
[Family] [nvarchar](150) NULL)
GO
SET IDENTITY_INSERT [dbo].[Tbl_TourTable] ON
INSERT [dbo].[Tbl_TourTable] ([ID], [Name], [Family]) VALUES (1,'name 1', 'family 1')
INSERT [dbo].[Tbl_TourTable] ([ID], [Name], [Family]) VALUES (1,'name 1', 'family 1')
INSERT [dbo].[Tbl_TourTable] ([ID], [Name], [Family]) VALUES (1,'name 1', 'family 1')
INSERT [dbo].[Tbl_TourTable] ([ID], [Name], [Family]) VALUES (1,'name 1', 'family 1')
INSERT [dbo].[Tbl_TourTable] ([ID], [Name], [Family]) VALUES (1,'name 1', 'family 1')
INSERT [dbo].[Tbl_TourTable] ([ID], [Name], [Family]) VALUES (1,'name 1', 'family 1')
INSERT [dbo].[Tbl_TourTable] ([ID], [Name], [Family]) VALUES (1,'name 1', 'family 1')
SET IDENTITY_INSERT [dbo].[Tbl_TourTable] off
You can also get this error if the objects you're passing to the method are out of order. In other words say your method takes, in order, a string, an integer, and a date. If you pass a date, then a string, then an integer you will get the same error message.
Steps to solve this problem
note: This problem mainly occurs due to which we haven't assigned our user name and email id in git so what we gonna do is assigning it in git
Open git that you have installed
Now we have to assign our user name and email id
Just type git config --user.name <your_name>
and click enter
(you can mention or type any name you want)
Similarly type git config --user.email <[email protected]>
and
click enter (you have to type your primary mail id)
And that's it.
Have a Good Day!!!.
For anyone seeking a solution that does not use the command line: ctrl+shift+t
that is the right behavior.
if you set @item1
to a value the below expression will be true
IF (@item1 IS NOT NULL) OR (LEN(@item1) > 0)
Anyway in SQL Server there is not a such function but you can create your own:
CREATE FUNCTION dbo.IsNullOrEmpty(@x varchar(max)) returns bit as
BEGIN
IF @SomeVarcharParm IS NOT NULL AND LEN(@SomeVarcharParm) > 0
RETURN 0
ELSE
RETURN 1
END
Something like this could be useful:
char str[] = "0x1800785";
int num;
sscanf(str, "%x", &num);
printf("0x%x %i\n", num, num);
Read man sscanf
ALTER TABLE `users` ADD COLUMN
`COLUMN NAME` DATATYPE(SIZE) AFTER `EXISTING COLUMN NAME`;
You can do it with this, working fine for me.
I think what you want to do is
<link rel="stylesheet" type="text/css" href="font/font-face/my-font-face.css">

The following code could be used to not use the string type:
int decimalResult = 789.500
while (decimalResult>0 && decimalResult % 10 == 0)
{
decimalResult = decimalResult / 10;
}
return decimalResult;
Returns 789.5
In case you need a declarative solution, you can use dict.update()
to change values in a dict.
Either like this:
my_dict.update({'key1': 'value1', 'key2': 'value2'})
or like this:
my_dict.update(key1='value1', key2='value2')
Since Python 3.5 you can also use dictionary unpacking for this:
my_dict = { **my_dict, 'key1': 'value1', 'key2': 'value2'}
Note: This creates a new dictionary.
Since Python 3.9 you can also use the merge operator on dictionaries:
my_dict = my_dict | {'key1': 'value1', 'key2': 'value2'}
Note: This creates a new dictionary.
Or you can use the update operator:
my_dict |= {'key1': 'value1', 'key2': 'value2'}
Rank each of the squares with numeric scores. If a square is taken, move on to the next choice (sorted in descending order by rank). You're going to need to choose a strategy (there are two main ones for going first and three (I think) for second). Technically, you could just program all of the strategies and then choose one at random. That would make for a less predictable opponent.
'sprintf' will work fine, if your first argument is a pointer to a character (a pointer to a character is an array in 'c'), you'll have to make sure you have enough space for all the digits and a terminating '\0'. For example, If an integer uses 32 bits, it has up to 10 decimal digits. So your code should look like:
int i;
char s[11];
...
sprintf(s,"%ld", i);
You can try this: http://www.monkey-business.biz/88/horizontal-zentriertes-100-hohe-css-layout/ That's 100% height and horizontal center.
You can try something like below
$($.parseHTML(<<table html string variable here>>)).find("td:contains('<<some text to find>>')").first().prev().text();
This is a simple solution where we do not need to use JSON
public interface RegisterAPI {
@FormUrlEncoded
@POST("/RetrofitExample/insert.php")
public void insertUser(
@Field("name") String name,
@Field("username") String username,
@Field("password") String password,
@Field("email") String email,
Callback<Response> callback);
}
method to send data
private void insertUser(){
//Here we will handle the http request to insert user to mysql db
//Creating a RestAdapter
RestAdapter adapter = new RestAdapter.Builder()
.setEndpoint(ROOT_URL) //Setting the Root URL
.build(); //Finally building the adapter
//Creating object for our interface
RegisterAPI api = adapter.create(RegisterAPI.class);
//Defining the method insertuser of our interface
api.insertUser(
//Passing the values by getting it from editTexts
editTextName.getText().toString(),
editTextUsername.getText().toString(),
editTextPassword.getText().toString(),
editTextEmail.getText().toString(),
//Creating an anonymous callback
new Callback<Response>() {
@Override
public void success(Response result, Response response) {
//On success we will read the server's output using bufferedreader
//Creating a bufferedreader object
BufferedReader reader = null;
//An string to store output from the server
String output = "";
try {
//Initializing buffered reader
reader = new BufferedReader(new InputStreamReader(result.getBody().in()));
//Reading the output in the string
output = reader.readLine();
} catch (IOException e) {
e.printStackTrace();
}
//Displaying the output as a toast
Toast.makeText(MainActivity.this, output, Toast.LENGTH_LONG).show();
}
@Override
public void failure(RetrofitError error) {
//If any error occured displaying the error as toast
Toast.makeText(MainActivity.this, error.toString(),Toast.LENGTH_LONG).show();
}
}
);
}
Now we can get the post request using php aur any other server side scripting.

Not trying to resurrect an inactive post, but since this hasn't been posted yet...
(This is how I did it before finding this question)
s = "hello"
target = "l"
last_pos = len(s) - 1 - s[::-1].index(target)
Explanation: When you're searching for the last occurrence, really you're searching for the first occurrence in the reversed string. Knowing this, I did s[::-1]
(which returns a reversed string), and then indexed the target
from there. Then I did len(s) - 1 - the index found
because we want the index in the unreversed (i.e. original) string.
Watch out, though! If target
is more than one character, you probably won't find it in the reversed string. To fix this, use last_pos = len(s) - 1 - s[::-1].index(target[::-1])
, which searches for a reversed version of target
.
COALESCE(field, 'default')
For example:
SELECT
t.id,
COALESCE(d.field, 'default')
FROM
test t
LEFT JOIN
detail d ON t.id = d.item
Also, you can use multiple columns to check their NULL
by COALESCE function.
For example:
mysql> SELECT COALESCE(NULL, 1, NULL);
-> 1
mysql> SELECT COALESCE(0, 1, NULL);
-> 0
mysql> SELECT COALESCE(NULL, NULL, NULL);
-> NULL
You can write a small script (look at Ian Clelland's answer) called git-commitall
which uses several git commands to perform what you want to do.
Place this script in your anywhere in your $PATH
. You can call it by git commitall
... very handy!
Found here (question and all answers unfortunately deleted, only visible with high reputation)
You need to read and write document.cookie
if (document.cookie.indexOf("visited=") >= 0) {
// They've been here before.
alert("hello again");
}
else {
// set a new cookie
expiry = new Date();
expiry.setTime(expiry.getTime()+(10*60*1000)); // Ten minutes
// Date()'s toGMTSting() method will format the date correctly for a cookie
document.cookie = "visited=yes; expires=" + expiry.toGMTString();
alert("this is your first time");
}
Just escape your quotes:
echo "<script>$('#edit_errors').html('<h3><em><font color=\"red\">Please Correct Errors Before Proceeding</font></em></h3>')</script>";
Assume you wanna create folder abc/123/ in your bucket, it's a piece of cake with Boto
k = bucket.new_key('abc/123/')
k.set_contents_from_string('')
Or use the console
You can use this simple script to see commits that are not merged
#!/bin/bash
# Show commits that exists only on branch and not in current
# Usage:
# git branch-notmerge <branchname>
#
# Setup git alias
# git config alias.branch-notmerge [path/to/this/script]
grep -Fvf <(git log --pretty=format:'%H - %s') <(git log $1 --pretty=format:'%H - %s')
You can use also tool git-wtf that will display state of branches

All of my tasks (which need to be scheduled) for a website are kept within the website and called from a special page. I then wrote a simple Windows service which calls this page every so often. Once the page runs it returns a value. If I know there is more work to be done, I run the page again, right away, otherwise I run it in a little while. This has worked really well for me and keeps all my task logic with the web code. Before writing the simple Windows service, I used Windows scheduler to call the page every x minutes.
Another convenient way to run this is to use a monitoring service like Pingdom. Point their http check to the page which runs your service code. Have the page return results which then can be used to trigger Pingdom to send alert messages when something isn't right.
A quick definition of the "permanent generation":
"The permanent generation is used to hold reflective data of the VM itself such as class objects and method objects. These reflective objects are allocated directly into the permanent generation, and it is sized independently from the other generations." [ref]
In other words, this is where class definitions go (and this explains why you may get the message OutOfMemoryError: PermGen space
if an application loads a large number of classes and/or on redeployment).
Note that PermSize
is additional to the -Xmx
value set by the user on the JVM options. But MaxPermSize
allows for the JVM to be able to grow the PermSize
to the amount specified. Initially when the VM is loaded, the MaxPermSize
will still be the default value (32mb for -client
and 64mb for -server
) but will not actually take up that amount until it is needed. On the other hand, if you were to set BOTH PermSize
and MaxPermSize
to 256mb, you would notice that the overall heap has increased by 256mb additional to the -Xmx
setting.
ResponseEntity
is meant to represent the entire HTTP response. You can control anything that goes into it: status code, headers, and body.
@ResponseBody
is a marker for the HTTP response body and @ResponseStatus
declares the status code of the HTTP response.
@ResponseStatus
isn't very flexible. It marks the entire method so you have to be sure that your handler method will always behave the same way. And you still can't set the headers. You'd need the HttpServletResponse
or a HttpHeaders
parameter.
Basically, ResponseEntity
lets you do more.
In Objective-C, a @synchronized
block handles locking and unlocking (as well as possible exceptions) automatically for you. The runtime dynamically essentially generates an NSRecursiveLock that is associated with the object you're synchronizing on. This Apple documentation explains it in more detail. This is why you're not seeing the log messages from your NSLock subclass — the object you synchronize on can be anything, not just an NSLock.
Basically, @synchronized (...)
is a convenience construct that streamlines your code. Like most simplifying abstractions, it has associated overhead (think of it as a hidden cost), and it's good to be aware of that, but raw performance is probably not the supreme goal when using such constructs anyway.
The values you provided are UTF-8 values. When set, the array of:
declare -a ARR=(0xA7 0x9B 0x46 0x8D 0x1E 0x52 0xA7 0x9B 0x7B 0x31 0xD2)
Will be parsed to print the plaintext characters of each value.
for ((n=0; n < ${#ARR[*]}; n++)); do echo -e "\u${ARR[$n]//0x/}"; done
And the output will yield a few printable characters and some non-printable characters as shown here:
For converting hex values to plaintext using the echo
command:
echo -e "\x<hex value here>"
And for converting UTF-8 values to plaintext using the echo
command:
echo -e "\u<UTF-8 value here>"
And then for converting octal to plaintext using the echo
command:
echo -e "\0<octal value here>"
When you have encoding values you aren't familiar with, take the time to check out the ranges in the common encoding schemes to determine what encoding a value belongs to. Then conversion from there is a snap.
Use empty
(it checks both nullness and emptiness) and group the nested ternary expression by parentheses (EL is in certain implementations/versions namely somewhat problematic with nested ternary expressions). Thus, so:
styleClass="#{empty obj.validationErrorMap ? ' ' :
(obj.validationErrorMap.contains('key') ? 'highlight_field' : 'highlight_row')}"
If still in vain (I would then check JBoss EL configs), use the "normal" EL approach:
styleClass="#{empty obj.validationErrorMap ? ' ' :
(obj.validationErrorMap['key'] ne null ? 'highlight_field' : 'highlight_row')}"
Update: as per the comments, the Map
turns out to actually be a List
(please work on your naming conventions). To check if a List
contains an item the "normal" EL way, use JSTL fn:contains
(although not explicitly documented, it works for List
as well).
styleClass="#{empty obj.validationErrorMap ? ' ' :
(fn:contains(obj.validationErrorMap, 'key') ? 'highlight_field' : 'highlight_row')}"
Use this method and pass your array in parameter
Collections.shuffle(arrayList);
This method return void so it will not give you a new list but as we know that array is passed as a reference type in Java so it will shuffle your array and save shuffled values in it. That's why you don't need any return type.
You can now use arraylist which is shuffled.

Is there any way you could programatically apply a class to the object?
<object class="hasparams">
then do
object.hasparams
I came across this thread when I have the same problem. I only need to get the first element then I re-analyze my code until this came up to my mind.
$firstElement = true;
foreach ($reportData->result() as $row)
{
if($firstElement) { echo "first element"; $firstElement=false; }
// Other lines of codes here
}
The above codes are great and complete but if you only need just the first element then you may try this code.
I did not try this, but what happens when you use :status
twice to check for NULL
?
Query query = getSession().createQuery(
"from CountryDTO c where ( c.status = :status OR ( c.status IS NULL AND :status IS NULL ) ) and c.type =:type"
)
.setParameter("status", status, Hibernate.STRING)
.setParameter("type", type, Hibernate.STRING);
Another approach, if you're desperate and don't have access to (a) the code or (b) the command line, then you can use environment variables:
http://docs.oracle.com/javase/7/docs/webnotes/tsg/TSG-Desktop/html/plugin.html.
Specifically for java web start set the environment variable:
JAVAWS_VM_ARGS
and for applets:
_JPI_VM_OPTIONS
e.g.
_JPI_VM_OPTIONS=-Djava.net.preferIPv4Stack=true
Additionally, under Windows global options (for general Java applications) can be set in the Java control plan page under the "Java" tab.
for displaying variables only in playground, just mention the variable name without anything
let stat = 100
stat // this outputs the value of stat on playground right window
Use hamcrest Matcher containsString()
// Hamcrest assertion
assertThat(person.getName(), containsString("myName"));
// Error Message
java.lang.AssertionError:
Expected: a string containing "myName"
got: "some other name"
You can optional add an even more detail error message.
// Hamcrest assertion with custom error message
assertThat("my error message", person.getName(), containsString("myName"));
// Error Message
java.lang.AssertionError: my error message
Expected: a string containing "myName"
got: "some other name"

I use the following:
Date.prototype.getUTCTime = function(){
return this.getTime()-(this.getTimezoneOffset()*60000);
};
Once defined this method you can do:
var utcTime = new Date().getUTCTime();
How about this:
import unicodedata
def strip_accents(s):
return ''.join(c for c in unicodedata.normalize('NFD', s)
if unicodedata.category(c) != 'Mn')
This works on greek letters, too:
>>> strip_accents(u"A \u00c0 \u0394 \u038E")
u'A A \u0394 \u03a5'
>>>
The character category "Mn" stands for Nonspacing_Mark
, which is similar to unicodedata.combining in MiniQuark's answer (I didn't think of unicodedata.combining, but it is probably the better solution, because it's more explicit).
And keep in mind, these manipulations may significantly alter the meaning of the text. Accents, Umlauts etc. are not "decoration".
No problem. Just use the following. This will behave exactly like serializing a form but using a div's content instead.
$('#divId :input').serialize();

As @Hesham Eraqi suggested, it worked for me in this way (transfering from Ubuntu to Windows (I tried to add a comment in that answer but because of reputation, I couldn't)):
pscp -v -r -P 53670 [email protected]:/data/genetic_map/sample/P2_283/* \\Desktop-mojbd3n\d\cc_01-1940_data\
where:
-v
: show verbose messages.
-r
: copy directories recursively.
-P
: connect to specified port.
53670
: the port number to connect the Ubuntu server.
\\Desktop-mojbd3n\d\genetic_map_data\
: I needed to transfer to an external HDD, thus I had to give permissions of sharing to this device.

CREATE TABLE [dbo].[Names]
(
[Name] [nvarchar](64) NOT NULL,
[CreateTS] [smalldatetime] NOT NULL CONSTRAINT CreateTS_DF DEFAULT CURRENT_TIMESTAMP,
[UpdateTS] [smalldatetime] NOT NULL
)
PS I think a smalldatetime is good enough. You may decide differently.
Can you not do this at the "moment of impact" ?
In Sql Server, this is common:
Update dbo.MyTable
Set
ColA = @SomeValue ,
UpdateDS = CURRENT_TIMESTAMP
Where...........
Sql Server has a "timestamp" datatype.
But it may not be what you think.
Here is a reference:
http://msdn.microsoft.com/en-us/library/ms182776(v=sql.90).aspx
Here is a little RowVersion (synonym for timestamp) example:
CREATE TABLE [dbo].[Names]
(
[Name] [nvarchar](64) NOT NULL,
RowVers rowversion ,
[CreateTS] [datetime] NOT NULL CONSTRAINT CreateTS_DF DEFAULT CURRENT_TIMESTAMP,
[UpdateTS] [datetime] NOT NULL
)
INSERT INTO dbo.Names (Name,UpdateTS)
select 'John' , CURRENT_TIMESTAMP
UNION ALL select 'Mary' , CURRENT_TIMESTAMP
UNION ALL select 'Paul' , CURRENT_TIMESTAMP
select * , ConvertedRowVers = CONVERT(bigint,RowVers) from [dbo].[Names]
Update dbo.Names Set Name = Name
select * , ConvertedRowVers = CONVERT(bigint,RowVers) from [dbo].[Names]
Maybe a complete working example:
DROP TABLE [dbo].[Names]
GO
CREATE TABLE [dbo].[Names]
(
[Name] [nvarchar](64) NOT NULL,
RowVers rowversion ,
[CreateTS] [datetime] NOT NULL CONSTRAINT CreateTS_DF DEFAULT CURRENT_TIMESTAMP,
[UpdateTS] [datetime] NOT NULL
)
GO
CREATE TRIGGER dbo.trgKeepUpdateDateInSync_ByeByeBye ON dbo.Names
AFTER INSERT, UPDATE
AS
BEGIN
Update dbo.Names Set UpdateTS = CURRENT_TIMESTAMP from dbo.Names myAlias , inserted triggerInsertedTable where
triggerInsertedTable.Name = myAlias.Name
END
GO
INSERT INTO dbo.Names (Name,UpdateTS)
select 'John' , CURRENT_TIMESTAMP
UNION ALL select 'Mary' , CURRENT_TIMESTAMP
UNION ALL select 'Paul' , CURRENT_TIMESTAMP
select * , ConvertedRowVers = CONVERT(bigint,RowVers) from [dbo].[Names]
Update dbo.Names Set Name = Name , UpdateTS = '03/03/2003' /* notice that even though I set it to 2003, the trigger takes over */
select * , ConvertedRowVers = CONVERT(bigint,RowVers) from [dbo].[Names]
Matching on the "Name" value is probably not wise.
Try this more mainstream example with a SurrogateKey
DROP TABLE [dbo].[Names]
GO
CREATE TABLE [dbo].[Names]
(
SurrogateKey int not null Primary Key Identity (1001,1),
[Name] [nvarchar](64) NOT NULL,
RowVers rowversion ,
[CreateTS] [datetime] NOT NULL CONSTRAINT CreateTS_DF DEFAULT CURRENT_TIMESTAMP,
[UpdateTS] [datetime] NOT NULL
)
GO
CREATE TRIGGER dbo.trgKeepUpdateDateInSync_ByeByeBye ON dbo.Names
AFTER UPDATE
AS
BEGIN
UPDATE dbo.Names
SET UpdateTS = CURRENT_TIMESTAMP
From dbo.Names myAlias
WHERE exists ( select null from inserted triggerInsertedTable where myAlias.SurrogateKey = triggerInsertedTable.SurrogateKey)
END
GO
INSERT INTO dbo.Names (Name,UpdateTS)
select 'John' , CURRENT_TIMESTAMP
UNION ALL select 'Mary' , CURRENT_TIMESTAMP
UNION ALL select 'Paul' , CURRENT_TIMESTAMP
select * , ConvertedRowVers = CONVERT(bigint,RowVers) from [dbo].[Names]
Update dbo.Names Set Name = Name , UpdateTS = '03/03/2003' /* notice that even though I set it to 2003, the trigger takes over */
select * , ConvertedRowVers = CONVERT(bigint,RowVers) from [dbo].[Names]
There are 2 reasons you may append rows in a loop, 1. add to an existing df, and 2. create a new df.
to create a new df, I think its well documented that you should either create your data as a list and then create the data frame:
cols = ['c1', 'c2', 'c3']
lst = []
for a in range(2):
lst.append([1, 2, 3])
df1 = pd.DataFrame(lst, columns=cols)
df1
Out[3]:
c1 c2 c3
0 1 2 3
1 1 2 3
OR, Create the dataframe with an index and then add to it
cols = ['c1', 'c2', 'c3']
df2 = pd.DataFrame(columns=cols, index=range(2))
for a in range(2):
df2.loc[a].c1 = 4
df2.loc[a].c2 = 5
df2.loc[a].c3 = 6
df2
Out[4]:
c1 c2 c3
0 4 5 6
1 4 5 6
If you want to add to an existing dataframe, you could use either method above and then append the df's together (with or without the index):
df3 = df2.append(df1, ignore_index=True)
df3
Out[6]:
c1 c2 c3
0 4 5 6
1 4 5 6
2 1 2 3
3 1 2 3
Or, you can also create a list of dictionary entries and append those as in the answer above.
lst_dict = []
for a in range(2):
lst_dict.append({'c1':2, 'c2':2, 'c3': 3})
df4 = df1.append(lst_dict)
df4
Out[7]:
c1 c2 c3
0 1 2 3
1 1 2 3
0 2 2 3
1 2 2 3
Using the dict(zip(cols, vals)))
lst_dict = []
for a in range(2):
vals = [7, 8, 9]
lst_dict.append(dict(zip(cols, vals)))
df5 = df1.append(lst_dict)
You might find Microsoft Network Monitor helpful if you're on Windows.
I agree that all the answers so far are correct, but here is the reason. Microsoft's C and C++ compilers provide various calling conventions for (intended) speed of function calls within an application's C and C++ functions. In each case, the caller and callee must agree on which calling convention to use. Now, Windows itself provides functions (APIs), and those have already been compiled, so when you call them you must conform to them. Any calls to Windows APIs, and callbacks from Windows APIs, must use the __stdcall convention.

v.invalidate();
break;

case MotionEvent.ACTION_UP: {

}
return false;

the Perl cookbook contains several iterations of a script "pmdesc" that does what you want. Google-search for "Perl Cookbook pmdesc" and you'll find articles on other Q&A Sites, several code listings on the net, a discussion of the solution, and even some refinements.
I use FPDF for ASP, and the iconv function is not available. It seems strange, by I solved the UTF-8 problem by adding a fake image (an 1x1px jpeg) to the pdf, just after the AddPage() function:
pdf.Image "images/fpdf.jpg",0,0,1
In this way, accented characters are correctly added to my pdf, don't ask me why but it works.
I got the solution just share with you that will work who got the errors:
1. First check the /home/hadoop/etc/hadoop path, hdfs-site.xml and
check the path of namenode and datanode
<property>
<name>dfs.name.dir</name>
<value>file:///home/hadoop/hadoopdata/hdfs/namenode</value>
</property>
<property>
<name>dfs.data.dir</name>
<value>file:///home/hadoop/hadoopdata/hdfs/datanode</value>
</property>
2.Check the permission,group and user of namenode and datanode of the particular path(/home/hadoop/hadoopdata/hdfs/datanode), and check if there are any problems in all of them and if there are any mismatch then correct it. ex .chown -R hadoop:hadoop in_use.lock, change user and group
chmod -R 755 <file_name> for change the permission
I had a case in where I was needing to use a data frame within a for loop function. In this case, it was the "efficient", however, keep in mind that the database was small and the iterations in the loop were very simple. But maybe the code could be useful for some one with similar conditions.
The for loop purpose was to use the raster extract function along five locations (i.e. 5 Tokio, New York, Sau Paulo, Seul & Mexico city) and each location had their respective raster grids. I had a spatial point database with more than 1000 observations allocated within the 5 different locations and I was needing to extract information from 10 different raster grids (two grids per location). Also, for the subsequent analysis, I was not only needing the raster values but also the unique ID for each observations.
After preparing the spatial data, which included the following tasks:
Here the for loop code with the use of a data frame:
1. Add stacked rasters per location into a list
raslist <- list(LOC1,LOC2,LOC3,LOC4,LOC5)
2. Create an empty dataframe, this will be the output file
TB <- data.frame(VAR1=double(),VAR2=double(),ID=character())
3. Set up for loop function
L1 <- seq(1,5,1) # the location ID is a numeric variable with values from 1 to 5
for (i in 1:length(L1)) {
dat=subset(points,LOCATION==i) # select corresponding points for location [i]
t=data.frame(extract(raslist[[i]],dat),dat$ID) # run extract function with points & raster stack for location [i]
names(t)=c("VAR1","VAR2","ID")
TB=rbind(TB,t)
}
Unfortunately, we do not have a "TRUNCATE TABLE" command in SQLite, but you can use SQLite's DELETE
command to delete the complete data from an existing table, though it is recommended to use the DROP TABLE
command to drop the complete table and re-create it once again.
You want to use position: absolute
while inside the other div.
I don't think that they are standardised macros. There are standardised functions for floating point already, fmax
and fmin
(and fmaxf
for floats, and fmaxl
for long doubles).
You can implement them as macros as long as you are aware of the issues of side-effects/double-evaluation.
#define MAX(a,b) ((a) > (b) ? a : b)
#define MIN(a,b) ((a) < (b) ? a : b)
In most cases, you can leave it to the compiler to determine what you're trying to do and optimise it as best it can. While this causes problems when used like MAX(i++, j++)
, I doubt there is ever much need in checking the maximum of incremented values in one go. Increment first, then check.

INSERT INTO Persons_Table (person_id, person_name,person_email)
SELECT person_id, customer_name, customer_email
FROM customer_table
ORDER BY `person_id` DESC LIMIT 0, 15
WHERE "insert your where clause here";
DELETE FROM customer_table
WHERE "repeat your where clause here";
You can also use ORDER BY, LIMIT and ASC/DESC to limit and select the specific column that you want to move.
If you're willing to include the jQuery UI library, in addition to jQuery itself, then you can simply use hide()
, with additional arguments, as follows:
$(document).ready(
function(){
$('#slider').click(
function(){
$(this).hide('slide',{direction:'right'},1000);
});
});
Without using jQuery UI, you could achieve your aim just using animate()
:
$(document).ready(
function(){
$('#slider').click(
function(){
$(this)
.animate(
{
'margin-left':'1000px'
// to move it towards the right and, probably, off-screen.
},1000,
function(){
$(this).slideUp('fast');
// once it's finished moving to the right, just
// removes the the element from the display, you could use
// `remove()` instead, or whatever.
}
);
});
});
If you do choose to use jQuery UI, then I'd recommend linking to the Google-hosted code, at: https://ajax.googleapis.com/ajax/libs/jqueryui/1.8.6/jquery-ui.min.js
If you want to sum
all values of one column, it's more efficient to use DataFrame

For as long as there is no official date and time picker from angular itself, I would advise to make a combination of the default angular date picker and this Angular Material Timepicker. I've chosen that one because all the other ones I found at this time lack support for issues, are outdated or are not functioning well in the most recent angular versions. This guy seems to be very responsive.
I've wrapped them both in one component so that it looks like it is one unit. You just have to make sure to do a few things:
When no input has been given yet, I would advise:
touchUi = true
on the datepicker, so that both the datepicker and the timepicker come as a dialog after each other.After a value has been given, it is clear that one part contains the time and the other part contains the date. At that moment it is clear that the user has to click on the time to change the time, and on the date to change the date. But before that, so when both fields are empty (and 'attached' to each other as one field) you should make sure the user cannot be confused by doing above recommendations.
My component is not complete yet, I will try to remember myself to share the code later. Shoot a comment if this question is more then a month old or so.

I think it still deserves some tweaks, as I think it can work a bit better when I would have more time creating this. Most importantly I tried to solve the UTC issue as well, so all dates should be shown in local time but should be sent to the server in UTC format (or at least saved with the correct timezone added to it).
You can use the CSS3 Linear Gradient property along with your background-image like this:
#landing-wrapper {
display:table;
width:100%;
background: linear-gradient( rgba(0, 0, 0, 0.5), rgba(0, 0, 0, 0.5) ), url('landingpagepic.jpg');
background-position:center top;
height:350px;
}
Here's a demo:
#landing-wrapper {_x000D_
display: table;_x000D_
width: 100%;_x000D_
background: linear-gradient(rgba(0, 0, 0, 0.5), rgba(0, 0, 0, 0.5)), url('http://placehold.it/350x150');_x000D_
background-position: center top;_x000D_
height: 350px;_x000D_
color: white;_x000D_
}
_x000D_
<div id="landing-wrapper">Lorem ipsum dolor ismet.</div>
_x000D_
For those that didn't find a good answer here, this is what we are doing to get a jar with all the necessary dependencies in it. This answer (https://stackoverflow.com/a/7623805/1084306) mentions to use the Maven Assembly plugin but doesn't actually give an example in the answer. And if you don't read all the way to the end of the answer (it's pretty lengthy), you may miss it. Adding the below to your pom.xml will generate target/${PROJECT_NAME}-${VERSION}-jar-with-dependencies.jar
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-assembly-plugin</artifactId>
<version>2.4.1</version>
<configuration>
<!-- get all project dependencies -->

</descriptorRefs>
<!-- MainClass in mainfest make a executable jar -->

Algorithm is:
1)Create a stack
2)while(end of input is not reached)
i)if the character read is not a sysmbol to be balanced ,ignore it.
ii)if the character is {,[,( then push it to stack
iii)If it is a },),] then if
a)the stack is empty report an error(catch it) i.e not balanced
b)else pop the stack
iv)if element popped is not corresponding to opening sysmbol,then report error.
3) In the end,if stack is not empty report error else expression is balanced.
In Java code:
public class StackDemo {
public static void main(String[] args) throws Exception {
System.out.println("--Bracket checker--");
CharStackArray stack = new CharStackArray(10);
stack.balanceSymbol("[a+b{c+(e-f[p-q])}]") ;
stack.display();
}
}
class CharStackArray {
private char[] array;
private int top;
private int capacity;
public CharStackArray(int cap) {
capacity = cap;
array = new char[capacity];
top = -1;
}
public void push(char data) {
array[++top] = data;
}
public char pop() {
return array[top--];
}
public void display() {
for (int i = 0; i <= top; i++) {
System.out.print(array[i] + "->");
}
}
public char peek() throws Exception {
return array[top];
}
/*Call this method by passing a string expression*/
public void balanceSymbol(String str) {
try {
char[] arr = str.toCharArray();
for (int i = 0; i < arr.length; i++) {
if (arr[i] == '[' || arr[i] == '{' || arr[i] == '(')
push(arr[i]);
else if (arr[i] == '}' && peek() == '{')
pop();
else if (arr[i] == ']' && peek() == '[')
pop();
else if (arr[i] == ')' && peek() == '(')
pop();
}
if (isEmpty()) {
System.out.println("String is balanced");
} else {
System.out.println("String is not balanced");
}
} catch (Exception e) {
System.out.println("String not balanced");
}
}
public boolean isEmpty() {
return (top == -1);
}
}
Output:
--Bracket checker--
String is balanced
Remove them. It's idiomatic to return from case
statements, and it's "unreachable code" noise otherwise.

**Explanation:
------------**
The best way to deal with showModalDialog for older application conversions is use to `https://github.com/niutech/showModalDialog` inorder to work with show modal dialogs and if modal dailog has ajax calls you need to create object and set the parameters of function to object and pass below...before that check for browser and set the useragent...example: agentStr = navigator.userAgent; and then check for chrome
var objAcceptReject={}; // create empty object and set the parameters to object and send to the other functions as dialog when opened in chrome breaks the functionality
function rejectClick(index, transferId) {
objAcceptReject.index=index;
objAcceptReject.transferId=transferId;
agentStr = navigator.userAgent;
var msie = ua.indexOf("MSIE ");
if (msie > 0) // If Internet Explorer, return version number
{
var ret = window.showModalDialog("/abc.jsp?accept=false",window,"dialogHeight:175px;dialogWidth:475px;scroll:no;status:no;help:no");
if (ret=="true") {
doSomeClick(index);
}
} else if ((agentStr.indexOf("Chrome")) >- 1){
spawn(function() {
var ret = window.showModalDialog("/abcd.jsp?accept=false",window,"dialogHeight:175px;dialogWidth:475px;scroll:no;status:no;help:no");
if (ret=="true") {// create an object and store values in objects and send as parameters
doSomeClick(objAcceptReject.index);
}
});
}
else {
var ret = window.showModalDialog("/xtz.jsp?accept=false",window,"dialogHeight:175px;dialogWidth:475px;scroll:no;status:no;help:no");
if (ret=="true") {
doSomeClick(index);
}
}
Try this function, it's ok to round up a double
'---------------Start -------------
Function Round_Up(ByVal d As Double) As Integer
Dim result As Integer
result = Math.Round(d)
If result >= d Then
Round_Up = result
Else
Round_Up = result + 1
End If
End Function
'-----------------End----------------
I'm sorry, I still yet cant comment, so to answer Tom's answer... In javascript (undefined != null) == false In fact that function wont work with "null", you should use "undefined"
Try this:
>>> f = open('goodlines.txt')
>>> mylist = f.readlines()
open()
function returns a file object. And for file object, there is no method like splitlines()
or split()
. You could use dir(f)
to see all the methods of file object.
for this error :"unable to load script from assets 'index.android.bundle'"
1). check for "assets" folder at : mkdir android\app\src\main\assets
if folder is not available ,create folder with name "assets" manually. and execute the Curl command in terminal.
2). Curl command: curl "http://localhost:8081/index.android.bundle?platform=android" -o"android/app/src/main/assets/index.android.bundle"
it will create the "index.android.bundle" file in assets folder automatically and resolved the issue.
3). react-native run-android
You have to change the mamp Mysql Database port into 8889.
If you are on a mysql server and if you don't mind loosing your tables, you can use a simple query to delete multiple tables at once:
SET foreign_key_checks = 0;
DROP TABLE IF EXISTS table_a,table_b,table_c,table_etc;
SET foreign_key_checks = 1;
In this way it doesn't matter in what order you use the table in you query.
If anybody is going to say something about the fact that this is not a good solution if you have a database with many tables: I agree!
Added jQuery.browser.webkit
to the "else if" for Chrome. Could not get this working in Chrome 23.
Made this script below for selecting the content in a <pre>
tag that has the class="code"
.
jQuery( document ).ready(function() {
jQuery('pre.code').attr('title', 'Click to select all');
jQuery( '#divFoo' ).click( function() {
var refNode = jQuery( this )[0];
if ( jQuery.browser.msie ) {
var range = document.body.createTextRange();
range.moveToElementText( refNode );
range.select();
} else if ( jQuery.browser.mozilla || jQuery.browser.opera || jQuery.browser.webkit ) {
var selection = refNode.ownerDocument.defaultView.getSelection();
console.log(selection);
var range = refNode.ownerDocument.createRange();
range.selectNodeContents( refNode );
selection.removeAllRanges();
selection.addRange( range );
} else if ( jQuery.browser.safari ) {
var selection = refNode.ownerDocument.defaultView.getSelection();
selection.setBaseAndExtent( refNode, 0, refNode, 1 );
}
} );
} );
For git mv
the
manual page
says
The index is updated after successful completion, […]
So, at first, you have to update the index on your own
(by using git add mobile.css
). However
git status
will still show two different files
$ git status
# On branch master
warning: LF will be replaced by CRLF in index.html
# Changes to be committed:
# (use "git reset HEAD <file>..." to unstage)
#
# modified: index.html
# new file: mobile.css
#
# Changed but not updated:
# (use "git add/rm <file>..." to update what will be committed)
# (use "git checkout -- <file>..." to discard changes in working directory)
#
# deleted: iphone.css
#
You can get a different output by running
git commit --dry-run -a
, which results in what you
expect:
Tanascius@H181 /d/temp/blo (master)
$ git commit --dry-run -a
# On branch master
warning: LF will be replaced by CRLF in index.html
# Changes to be committed:
# (use "git reset HEAD <file>..." to unstage)
#
# modified: index.html
# renamed: iphone.css -> mobile.css
#
I can't tell you exactly why we see these differences
between git status
and
git commit --dry-run -a
, but
here is a hint from
Linus:
git really doesn't even care about the whole "rename detection" internally, and any commits you have done with renames are totally independent of the heuristics we then use to show the renames.
A dry-run
uses the real renaming mechanisms, while a
git status
probably doesn't.
Improving upon @barry-stae and @Sandeep answers for regular users of elinks you would add the following to .bashrc:
function mdviewer() {
pandoc $* | elinks --force-html
}
Don't forget to install pandoc (and elinks).
This is not your answer and this is an alternate way to process the form submission
$('.signinform').click(function(e) {
e.preventDefault();
$.ajax({
type: "POST",
url: 'index.php/user/signin', // target element(s) to be updated with server response
dataType:'json',
success : function(response){ console.log(response); alert(response)}
});
});
An alternative solution is using an external table: http://www.orafaq.com/node/848
Use this when you have to do this import very often and very fast.
Use ===
to equate the variables instead of ==
.
==
checks if the value of the variables is similar
===
checks if the value of the variables and the type of the variables are similar
Notice how
if(0===false) {
document.write("oh!!! that's true");
}?
and
if(0==false) {
document.write("oh!!! that's true");
}?
give different results
If you want the algorithms to be implemented specifically in Java then there is Mitchell Waite's Series book "Data Structures & Algorithms in Java". It starts from basic data structures like linked lists, stacks and queues, and the basic algorithms for sorting and searching. Working your way through it you will eventually get to Tree data structures, Red-Black trees, 2-3 trees and Graphs.
All-in-all its not an extremely theoretical book, but if you just want an introduction in a language you are familiar with then its a good book. At the end of the day, if you want a deeper understanding of algorithms you're going to have to learn some of the more theoretical concepts, and read one of the classics, like Cormen/Leiserson/Rivest/Stein's Introduction to Algorithms.
The alternative and easier solution that i also use is to create custom marker layout and convert it into a bitmap.
view_custom_marker.xml
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/custom_marker_view"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="@drawable/marker_mask">
<ImageView
android:id="@+id/profile_image"
android:layout_width="48dp"
android:layout_height="48dp"
android:layout_gravity="center_horizontal"
android:contentDescription="@null"
android:src="@drawable/avatar" />
</FrameLayout>
Convert this view into bitmap by using the code below
private Bitmap getMarkerBitmapFromView(@DrawableRes int resId) {
View customMarkerView = ((LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE)).inflate(R.layout.view_custom_marker, null);
ImageView markerImageView = (ImageView) customMarkerView.findViewById(R.id.profile_image);
markerImageView.setImageResource(resId);
customMarkerView.measure(View.MeasureSpec.UNSPECIFIED, View.MeasureSpec.UNSPECIFIED);
customMarkerView.layout(0, 0, customMarkerView.getMeasuredWidth(), customMarkerView.getMeasuredHeight());
customMarkerView.buildDrawingCache();
Bitmap returnedBitmap = Bitmap.createBitmap(customMarkerView.getMeasuredWidth(), customMarkerView.getMeasuredHeight(),
Bitmap.Config.ARGB_8888);
Canvas canvas = new Canvas(returnedBitmap);
canvas.drawColor(Color.WHITE, PorterDuff.Mode.SRC_IN);
Drawable drawable = customMarkerView.getBackground();
if (drawable != null)
drawable.draw(canvas);
customMarkerView.draw(canvas);
return returnedBitmap;
}
Add your custom marker in on Map ready callback.
@Override
public void onMapReady(GoogleMap googleMap) {
Log.d(TAG, "onMapReady() called with");
mGoogleMap = googleMap;
MapsInitializer.initialize(this);
addCustomMarker();
}
private void addCustomMarker() {
Log.d(TAG, "addCustomMarker()");
if (mGoogleMap == null) {
return;
}
// adding a marker on map with image from drawable
mGoogleMap.addMarker(new MarkerOptions()
.position(mDummyLatLng)
.icon(BitmapDescriptorFactory.fromBitmap(getMarkerBitmapFromView(R.drawable.avatar))));
}

I had this exact problem and this worked:
