Here you go:
InputStream is = new ByteArrayInputStream( myString.getBytes() );
Update For multi-byte support use (thanks to Aaron Waibel's comment):
InputStream is = new ByteArrayInputStream(Charset.forName("UTF-16").encode(myString).array());
Please see ByteArrayInputStream manual.
It is safe to use a charset argument in String#getBytes(charset) method above.
After JDK 7+ you can use
java.nio.charset.StandardCharsets.UTF_16
instead of hardcoded encoding string:
InputStream is = new ByteArrayInputStream(StandardCharsets.UTF_16.encode(myString).array());
Not knowing your code, it's a bit hard to answer your question, but based on all the info here, I believe the issue is you're trying to use Collections.sort passing in an object defined as Collection, and sort doesn't support that.
First question. Why is client defined so generically? Why isn't it a List, Map, Set or something a little more specific?
If client was defined as a List, Map or Set, you wouldn't have this issue, as then you'd be able to directly use Collections.sort(client).

As you can see, the AND operator drops every row in which at least one value equals -1. On the other hand, the OR operator requires both values to be equal to -1 to drop them.
That's right. Remember that you're writing the condition in terms of what you want to keep, not in terms of what you want to drop. For df1:
df1 = df[(df.a != -1) & (df.b != -1)]
You're saying "keep the rows in which df.a isn't -1 and df.b isn't -1", which is the same as dropping every row in which at least one value is -1.
For df2:
df2 = df[(df.a != -1) | (df.b != -1)]
You're saying "keep the rows in which either df.a or df.b is not -1", which is the same as dropping rows where both values are -1.
PS: chained access like df['a'][1] = -1 can get you into trouble. It's better to get into the habit of using .loc and .iloc.

You would need to do something like this. I am typing this off the top of my head, so this may not be 100% correct.
CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceRGB(); CGContextRef context = CGBitmapContextCreate(NULL, 640, 360, 8, 4 * width, colorSpace, kCGImageAlphaPremultipliedFirst); CGColorSpaceRelease(colorSpace); CGContextDrawImage(context, CGRectMake(0,-160,640,360), cgImgFromAVCaptureSession); CGImageRef image = CGBitmapContextCreateImage(context); UIImage* myCroppedImg = [UIImage imageWithCGImage:image]; CGContextRelease(context); save() method can be used to insert new record and update existing record and generally used for saving instance of single record(row in mysql) in database.
update() is not used to insert records and can be used to update multiple records(rows in mysql) in database.
We had the same problem on a CentOS7 machine. Disabling the VERIFYHOST VERIFYPEER did not solve the problem, we did not have the cURL error anymore but the response still was invalid. Doing a wget to the same link as the cURL was doing also resulted in a certificate error.
-> Our solution also was to reboot the VPS, this solved it and we were able to complete the request again.
For us this seemed to be a memory corruption problem. Rebooting the VPS reloaded the libary in the memory again and now it works. So if the above solution from @clover does not work try to reboot your machine.

Yii way
\yii\helpers\StringHelper::basename(get_class($model));
Yii uses this method in its Gii code generator
Method documentation
This method is similar to the php function basename() except that it will treat both \ and / as directory separators, independent of the operating system. This method was mainly created to work on php namespaces. When working with real file paths, php's basename() should work fine for you. Note: this method is not aware of the actual filesystem, or path components such as "..".
More information:
https://github.com/yiisoft/yii2/blob/master/framework/helpers/BaseStringHelper.php http://www.yiiframework.com/doc-2.0/yii-helpers-basestringhelper.html#basename()-detail
The map function can be very useful here.
Using map we can apply any function to each element of an iterable.
Python 3.x
>>> def my_mul(x,y):
... return x*y
...
>>> a = [1,2,3,4]
>>> b = [2,3,4,5]
>>>
>>> list(map(my_mul,a,b))
[2, 6, 12, 20]
>>>
Of course:
map(f, iterable)
is equivalent to
[f(x) for x in iterable]
So we can get our solution via:
>>> [my_mul(x,y) for x, y in zip(a,b)]
[2, 6, 12, 20]
>>>
In Python 2.x map() means: apply a function to each element of an iterable and construct a new list.
In Python 3.x, map construct iterators instead of lists.
Instead of my_mul we could use mul operator
Python 2.7
>>>from operator import mul # import mul operator
>>>a = [1,2,3,4]
>>>b = [2,3,4,5]
>>>map(mul,a,b)
[2, 6, 12, 20]
>>>
Python 3.5+
>>> from operator import mul
>>> a = [1,2,3,4]
>>> b = [2,3,4,5]
>>> [*map(mul,a,b)]
[2, 6, 12, 20]
>>>
Please note that since map() constructs an iterator we use * iterable unpacking operator to get a list.
The unpacking approach is a bit faster then the list constructor:
>>> list(map(mul,a,b))
[2, 6, 12, 20]
>>>
A bit late probably but now there is PDOStatement::debugDumpParams
Dumps the informations contained by a prepared statement directly on the output. It will provide the SQL query in use, the number of parameters used (Params), the list of parameters, with their name, type (paramtype) as an integer, their key name or position, and the position in the query (if this is supported by the PDO driver, otherwise, it will be -1).
You can find more on the official php docs
Example:
<?php
/* Execute a prepared statement by binding PHP variables */
$calories = 150;
$colour = 'red';
$sth = $dbh->prepare('SELECT name, colour, calories
FROM fruit
WHERE calories < :calories AND colour = :colour');
$sth->bindParam(':calories', $calories, PDO::PARAM_INT);
$sth->bindValue(':colour', $colour, PDO::PARAM_STR, 12);
$sth->execute();
$sth->debugDumpParams();
?>

Ok, it's actually simple. Assuming that your macro is in a module,not in one of the sheets, you use:
objExcel.Application.Run "test.xls!dog"
'notice the format of 'workbook name'!macro
For a filename with spaces, encase the filename with quotes.
If you've placed the macro under a sheet, say sheet1, just assume sheet1 owns the function, which it does.
objExcel.Application.Run "'test 2.xls'!sheet1.dog"
Notice: You don't need the macro.testfunction notation you've been using.
Check the static Nullable.GetUnderlyingType.
- If the underlying type is null, then the template parameter is not Nullable, and we can use that type directly
- If the underlying type is not null, then use the underlying type in the conversion.
Seems to work for me:
public object Get( string _toparse, Type _t )
{
// Test for Nullable<T> and return the base type instead:
Type undertype = Nullable.GetUnderlyingType(_t);
Type basetype = undertype == null ? _t : undertype;
return Convert.ChangeType(_toparse, basetype);
}
public T Get<T>(string _key)
{
return (T)Get(_key, typeof(T));
}
public void test()
{
int x = Get<int>("14");
int? nx = Get<Nullable<int>>("14");
}
WE had this issue. everything was setup fine in terms of permissions and security.
after MUCH needling around in the haystack. the issue was some sort of heuristics. in the email body , anytime a certain email address was listed, we would get the above error message from our exchange server.
it took 2 days of crazy testing and hair pulling to find this.
so if you have checked everything out, try changing the email body to only the word 'test'. If after that, your email goes out fine, you are having some sort of spam/heuristic filter issue like we were

This is what i did for merging two datatables and bind the final result to the gridview
DataTable dtTemp=new DataTable();
for (int k = 0; k < GridView2.Rows.Count; k++)
{
string roomno = GridView2.Rows[k].Cells[1].Text;
DataTable dtx = GetRoomDetails(chk, roomno, out msg);
if (dtx.Rows.Count > 0)
{
dtTemp.Merge(dtx);
dtTemp.AcceptChanges();
}
}
for alternative you can use as below:
if (variable >= 5 && variable <= 100) {
doSomething();
}
or the following code also works
switch (variable)
{
case 5:
case 6:
etc.
case 100:
doSomething();
break;
}
Thank you for your responses. Turns out my problem was a database issue with duplicate entries, not with my logic. A quick table sync fixed that and the SUM feature worked as expected. This is all still useful knowledge for the SUM feature and is worth reading if you are having trouble using it.
Using Environment class we can get application. Properties values
@Autowired,
private Environment env;
and access using
String password =env.getProperty(your property key);
Although the accepted answer is absolutely clear, I just wanted to check efficiency in terms of time.
The best way is to print joined string of numbers converted to strings.
print(" ".join(list(map(str,l))))
Note that I used map instead of loop. I wrote a little code of all 4 different ways to compare time:
import time as t
a, b = 10, 210000
l = list(range(a, b))
tic = t.time()
for i in l:
print(i, end=" ")
print()
tac = t.time()
t1 = (tac - tic) * 1000
print(*l)
toe = t.time()
t2 = (toe - tac) * 1000
print(" ".join([str(i) for i in l]))
joe = t.time()
t3 = (joe - toe) * 1000
print(" ".join(list(map(str, l))))
toy = t.time()
t4 = (toy - joe) * 1000
print("Time",t1,t2,t3,t4)
Result:
Time 74344.76 71790.83 196.99 153.99
The output was quite surprising to me. Huge difference of time in cases of 'loop method' and 'joined-string method'.
Conclusion: Do not use loops for printing list if size is too large( in order of 10**5 or more).
Changing the Target Framework in project properties from .NET Framework 4.7.1 to 4.6.2 worked for me.
If you are only saving a single object (your data frame), you could also use saveRDS.
To save:
saveRDS(foo, file="data.Rda")
Then read it with:
bar <- readRDS(file="data.Rda")
The difference between saveRDS and save is that in the former only one object can be saved and the name of the object is not forced to be the same after you load it.
I got this same error as I mistakenly changed the order of the statements
OkHttpClient okHttpClient = new OkHttpClient().newBuilder() .connectTimeout(20, TimeUnit.SECONDS).readTimeout(20,TimeUnit.SECONDS).writeTimeout(20, TimeUnit.SECONDS) .build();
After changing the order of writeTimeout and readTimeout, the error resolved. The final code I used is given below:
OkHttpClient okHttpClient = new OkHttpClient.Builder().connectTimeout(60, TimeUnit.SECONDS)
.writeTimeout(60, TimeUnit.SECONDS)
.readTimeout(60, TimeUnit.SECONDS)
.build();
You may want to look at Tibbo VSPDL for creating a linux virtual serial port using a Kernel driver -- it seems pretty new, and is available for download right now (beta version). Not sure about the license at this point, or whether they want to make it available commercially only in the future.
There are other commercial alternatives, such as http://www.ttyredirector.com/.
In Open Source, Remserial (GPL) may also do what you want, using Unix PTY's. It transmits the serial data in "raw form" to a network socket; STTY-like setup of terminal parameters must be done when creating the port, changing them later like described in RFC 2217 does not seem to be supported. You should be able to run two remserial instances to create a virtual nullmodem like com0com, except that you'll need to set up port speed etc in advance.
Socat (also GPL) is like an extended variant of Remserial with many many more options, including a "PTY" method for redirecting the PTY to something else, which can be another instance of Socat. For Unit tets, socat is likely nicer than remserial because you can directly cat files into the PTY. See the PTY example on the manpage. A patch exists under "contrib" to provide RFC2217 support for negotiating serial line settings.

With CSS Shapes you can go one step further than just float text around a rectangular image.
You can actually wrap text such that it takes the shape of the edge of the image or polygon that you are wrapping it around.

A point of confusion sometimes is that to log a text message along with the contents of one of your objects using console.log, you have to pass each one of the two as a different argument. This means that you have to separate them by commas because if you were to use the + operator to concatenate the outputs, this would implicitly call the .toString() method of your object. This in most cases is not explicitly overriden and the default implementation inherited by Object doesn't provide any useful information.
Example to try in console:
>>> var myObj = {foo: 'bar'}
undefined
>>> console.log('myObj is: ', myObj);
myObj is: Object { foo= "bar"}
whereas if you tried to concatenate the informative text message along with the object's contents you'd get:
>>> console.log('myObj is: ' + myObj);
myObj is: [object Object]
So keep in mind that console.log in fact takes as many arguments as you like.
There are three ways to save objects from your R session:
The save.image() function will save all objects currently in your R session:
save.image(file="1.RData")
These objects can then be loaded back into a new R session using the load() function:
load(file="1.RData")
If you want to save some, but not all objects, you can use the save() function:
save(city, country, file="1.RData")
Again, these can be reloaded into another R session using the load() function:
load(file="1.RData")
If you want to save a single object you can use the saveRDS() function:
saveRDS(city, file="city.rds")
saveRDS(country, file="country.rds")
You can load these into your R session using the readRDS() function, but you will need to assign the result into a the desired variable:
city <- readRDS("city.rds")
country <- readRDS("country.rds")
But this also means you can give these objects new variable names if needed (i.e. if those variables already exist in your new R session but contain different objects):
city_list <- readRDS("city.rds")
country_vector <- readRDS("country.rds")
I think it would be the following, for example:
[ 2 << 1 ] is => [10 (binary of 2) add 1 zero at the end of the binary string] Hence 10 will be 100 which becomes 4.
Signed left shift uses multiplication... So this could also be calculated as 2 * (2^1) = 4. Another example [2 << 11] = 2 *(2^11) = 4096
[ 4 >> 1 ] is => [100 (binary of 4) remove 1 zero at the end of the binary string] Hence 100 will be 10 which becomes 2.
Signed right shift uses division... So this could also be calculated as 4 / (2^1) = 2 Another example [4096 >> 11] = 4096 / (2^11) = 2
Always check your code using shellcheck. It will often give you the correct answer. In this case SC2207 covers reading a file that either has space separated or newline separated values into an array.
array=( $(mycommand) )
mapfile -t array < <(mycommand)
IFS=" " read -r -a array <<< "$(mycommand)"
The shellcheck page will give you the rationale why this is considered best practice.
You organized class interface such that public members begin with "my". Therefore you must use only those members. Instead of
myScoreonHole.hole = Console.ReadLine();
you should write
myScoreonHole.myhole = Console.ReadLine();
I found some slides about this issue.
In this slides the author tells that it seems to be a problem with GC, if there are a lot of objects or huge objects in heap. The slide also include a reference to a sample app and a python script to analyze this issue.

Furthermore I found a hint in comment #3 on this side: https://code.google.com/p/android/issues/detail?id=53418#c3
Changing the data type to text helped dataType: 'text'
I have check with JSONlint and my json format was proper. Still it was throwing error when I set dataType: 'json'
JSON Data: {"eventinvite":1,"groupcount":8,"totalMessagesUnread":0,"unreadmessages":{"378":0,"379":0,"380":0,"385":0,"390":0,"393":0,"413":0,"418":0}}
The problem, as the Traceback says, comes from the line x[i+1] = x[i] + ( t[i+1] - t[i] ) * f( x[i], t[i] ). Let's replace it in its context:
i + 1 >= len(x) <=> i >= 0, the element x[i+1] doesn't exist. Here, this element doesn't exist since the beginning of the for loop.To solve this, you must replace x[i+1] = x[i] + ( t[i+1] - t[i] ) * f( x[i], t[i] ) by x.append(x[i] + ( t[i+1] - t[i] ) * f( x[i], t[i] )).
In this case, you could ( and probably would ) just define a Pizza base class and inherit from them. However, there are two reasons where Interfaces allow you to do things that cannot be achieved in other ways:
A class can implement multiple interfaces. It just defines features that the class must have. Implementing a range of interfaces means that a class can fulfil multiple functions in different places.
An interface can be defined in a hogher scope than the class or the caller. This means that you can separate the functionality, separate the project dependency, and keep the functionality in one project or class, and the implementation of this elsewhere.
One implication of 2 is that you can change the class that is being used, just requiring that it implements the appropriate interface.
try this (a2 is BLOB col)
PreparedStatement ps1 = conn.prepareStatement("update t1 set a2=? where id=1");
Blob blob = conn.createBlob();
blob.setBytes(1, str.getBytes());
ps1.setBlob(1, blob);
ps1.executeUpdate();
it may work even without BLOB, driver will transform types automatically:
ps1.setBytes(1, str.getBytes);
ps1.setString(1, str);
Besides if you work with text CLOB seems to be a more natural col type
You can use __halt_compiler function which will Halt the compiler execution
Check the PASSWORD_LOCK_TIME parameter. If it is set to 1 then you won't be able to unlock the password for 1 day even after you issue the alter user unlock command.
You can break from a forEach loop if you overwrite the Array method:
(function(){
window.broken = false;
Array.prototype.forEach = function(cb, thisArg) {
var newCb = new Function("with({_break: function(){window.broken = true;}}){("+cb.replace(/break/g, "_break()")+"(arguments[0], arguments[1], arguments[2]));}");
this.some(function(item, index, array){
newCb(item, index, array);
return window.broken;
}, thisArg);
window.broken = false;
}
}())
example:
[1,2,3].forEach("function(x){\
if (x == 2) break;\
console.log(x)\
}")
Unfortunately with this solution you can't use normal break inside your callbacks, you must wrap invalid code in strings and native functions don't work directly (but you can work around that)
Happy breaking!
If you mean you want the background image itself to be offset by 50 pixels from the top, like a background margin, then just switch out the top for 50px and you're set.
#thedivstatus {
background-image: url("imagestatus.gif");
background-position: right 50px;
background-repeat: no-repeat;
}
I dig a little bit more (during implementation of base128), and expose that when we send characters which ascii codes are bigger than 128 then browser (chrome) in fact send TWO characters (bytes) instead one :(. The reason is that JSON by defaul use utf8 characters for which characters with ascii codes above 127 are coded by two bytes what was mention by chmike answer. I made test in this way: type in chrome url bar chrome://net-export/ , select "Include raw bytes", start capturing, send POST requests (using snippet at the bottom), stop capturing and save json file with raw requests data. Then we look inside that json file:
4142434445464748494a4b4c4d4e this is hex coding of ABCDEFGHIJKLMN and we will see that "byte_count": 639 for it.C2BCC2BDC380C381C382C383C384C385C386C387C388C389C38AC38B this are request-hex utf8 codes of characters ¼½ÀÁÂÃÄÅÆÇÈÉÊË (however the ascii hex codes of this characters are c1c2c3c4c5c6c7c8c9cacbcccdce). The "byte_count": 703 so it is 64bytes longer than base64 request because characters with ascii codes above 127 are code by 2 bytes in request :(So in fact we don't have profit with sending characters with codes >127 :( . For base64 strings we not observe such negative behaviour (probably for base85 too - I don check it) - however may be some solution for this problem will be sending data in binary part of POST multipart/form-data described in Ælex answer (however usually in this case we don't need to use any base coding at all...).
The alternative approach may rely on mapping two bytes data portion into one valid utf8 character by code it using something like base65280 / base65k but probably it would be less effective than base64 due to utf8 specification ...

In the jsp your form should have an input field with name = "id" like the following:
<input type="text" name="id" />
<input type="submit" />
Then in your controller, your handler method should be like the following:
@RequestMapping("listNotes")
public String listNotes(@RequestParam("id") int id) {
Person person = personService.getCurrentlyAuthenticatedUser();
model.addAttribute("person", new Person());
model.addAttribute("listPersons", this.personService.listPersons());
model.addAttribute("listNotes", this.notesService.listNotesBySectionId(id, person));
return "note";
}
Please also refer to these answers and tutorial:
ex mode is easiest:
:%s/$/,
: - enter command mode
% - for every line
s/ - substitute
$ - the end of the line
/ - and change it to
, - a comma
Below I've incorporated suggestion from comments. Thank you al!
import hashlib
def checksum(filename, hash_factory=hashlib.md5, chunk_num_blocks=128):
h = hash_factory()

h = hash_factory()
with open(filename,'rb') as f:
while chunk := f.read(chunk_num_blocks*h.block_size):
h.update(chunk)
return h.digest()
if you care about more pythonic (no 'while True') way of reading the file check this code:
import hashlib
def checksum_md5(filename):
md5 = hashlib.md5()
with open(filename,'rb') as f:
for chunk in iter(lambda: f.read(8192), b''):
md5.update(chunk)
return md5.digest()
Note that the iter() func needs an empty byte string for the returned iterator to halt at EOF, since read() returns b'' (not just '').
If you want to dynamicallly display your Symfony 2 version in pages, for example in footer, you can do it this way.
Create a service:
<?php
namespace Project\Bundle\DuBundle\Twig;
class SymfonyVersionExtension extends \Twig_Extension
{
public function getFunctions()
{
return array(
//this is the name of the function you will use in twig
new \Twig_SimpleFunction('symfony_version', array($this, 'b'))
);
}
public function getName()
{
//return 'number_employees';
return 'symfony_version_extension';
}
public function b()
{
$symfony_version = \Symfony\Component\HttpKernel\Kernel::VERSION;
return $symfony_version;
}
}
Register in service.yml
dut.twig.symfony_version_extension:
class: Project\Bundle\DutBundle\Twig\SymfonyVersionExtension
tags:
- { name: twig.extension }
#arguments: []
And you can call it anywhere. In Controller, wrap it in JSON, or in pages example footer
<p> Built With Symfony {{ symfony_version() }} Version MIT License</p>
Now every time you run composer update to update your vendor, symfony version will also automatically update in your template.I know this is overkill but this is how I do it in my projects and it is working.
I needed to trim the values in a primary key column that had first and last names, so I did not want to trim all white space as that would remove the space between the first and last name, which I needed to keep. What worked for me was...
UPDATE `TABLE` SET `FIELD`= TRIM(FIELD);
or
UPDATE 'TABLE' SET 'FIELD' = RTRIM(FIELD);
or
UPDATE 'TABLE' SET 'FIELD' = LTRIM(FIELD);
Note that the first instance of FIELD is in single quotes but the second is not in quotes at all. I had to do it this way or it gave me a syntax error saying it was a duplicate primary key when I had both in quotes.
You can get value like this
this.form.controls['your form control name'].value
by this you can load html file which is in your project Assets(bundle) to webView.
UIWebView *web = [[UIWebView alloc] initWithFrame:CGRectMake(0, 0, 320, 460)];
[web loadRequest:[NSURLRequest requestWithURL:[NSURL fileURLWithPath:[[NSBundle mainBundle]
pathForResource:@"test" ofType:@"html"]isDirectory:NO]]];
may be this is useful to you.
In addition to the answers already given it will be quicker if you use OrElse instead of Or because the second test is short circuited. This is especially true if you know that one string is more likely than the other in which case place this first:
If strMyString.Contains("Most Likely To Find") OrElse strMyString.Contains("Less Likely to Find") Then
'Code
End if
if(isset($variable)){
$isTouch = $variable;
}
OR
if(!isset($variable)){
$isTouch = "";//
}
I found a solution that is more efficient than currently accepted answer, because current answer forces all list elements to be refreshed. My solution will refresh only one element (that was touched) by calling adapters getView and recycling current view which adds even more efficiency.
mListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
// Edit object data that is represented in Viewat at list's "position"
view = mAdapter.getView(position, view, parent);
}
});
Had the same problem and did two changes: (a) did not over-write existing data (not ideal if that is your intention but you can run a delete query beforehand), and (b) counted the columns and found that the csv had an empty column so it always pays to go back to your original work even though all 'seems' to look correct.
Look at SignalR Tests for the feature.
Test "SendToUser" takes automatically the user identity passed by using a regular owin authentication library.
The scenario is you have a user who has connected from multiple devices/browsers and you want to push a message to all his active connections.
I usually do this :
StringBuffer sb = new StringBuffer();
Iterator it = myList.iterator();
if (it.hasNext()) { sb.append(it.next().toString()); }
while (it.hasNext()) { sb.append(",").append(it.next().toString()); }
Though I think I'll to a this check from now on as per the Java implementation ;)
You need to pass the parameters to the stored procedure.
It should work like this:
List result = em
.createNativeQuery("call getEmployeeDetails(:employeeId,:companyId)")
.setParameter("emplyoyeeId", 123L)
.setParameter("companyId", 456L)
.getResultList();
Update:
Or maybe it shouldn't.
In the Book EJB3 in Action, it says on page 383, that JPA does not support stored procedures (page is only a preview, you don't get the full text, the entire book is available as a download in several places including this one, I don't know if this is legal though).
Anyway, the text is this:
If you’re a big fan of SQL, you may be willing to exploit the power of database stored procedures. Unfortunately, JPA doesn’t support stored procedures, and you have to depend on a proprietary feature of your persistence provider. However, you can use simple stored functions (without out parameters) with a native SQL query.
Here is a full program example of a for-each macro in C99:
#include <stdio.h>
typedef struct list_node list_node;
struct list_node {
list_node *next;
void *data;
};
#define FOR_EACH(item, list) \
for (list_node *(item) = (list); (item); (item) = (item)->next)
int
main(int argc, char *argv[])
{
list_node list[] = {
{ .next = &list[1], .data = "test 1" },
{ .next = &list[2], .data = "test 2" },
{ .next = NULL, .data = "test 3" }
};
FOR_EACH(item, list)
puts((char *) item->data);
return 0;
}
Its possible, but not directly.
In short, go to the search, use your regex, check "mark line" and click "Find all". It results in bookmarks for all those lines.
In the search menu there is a point "delete bookmarked lines" voila.
I found the answer here (the correct answer is the second one, not the accepted!): How to delete specific lines on Notepad++?
This is a response I got from their Premium Services
Hello,
This is actually a issue with the way SSL validates names containing a period, '.', > character. We've documented this behavior here:
http://docs.amazonwebservices.com/AmazonS3/latest/dev/BucketRestrictions.html
The only straight-forward fix for this is to use a bucket name that does not contain that character. You might instead use a bucket named 'furniture-retailcatalog-us'. This would allow you use HTTPS with
https://furniture-retailcatalog-us.s3.amazonaws.com/
You could, of course, put a CNAME DNS record to make that more friendly. For example,
images-furniture.retailcatalog.us IN CNAME furniture-retailcatalog-us.s3.amazonaws.com.
Hope that helps. Let us know if you have any other questions.
Amazon Web Services
Unfortunately your "friendly" CNAME will cause host name mismatch when validating the certificate, therefore you cannot really use it for a secure connection. A big missing feature of S3 is accepting custom certificates for your domains.
UPDATE 10/2/2012
From @mpoisot:
The link Amazon provided no longer says anything about https. I poked around in the S3 docs and finally found a small note about it on the Virtual Hosting page: http://docs.amazonwebservices.com/AmazonS3/latest/dev/VirtualHosting.html
UPDATE 6/17/2013
From @Joseph Lust:

If it's a text file why not use apache commons-io?

I was able to get a great solution to this problem with iScroll, with the feel of momentum scrolling and everything https://github.com/cubiq/iscroll The github doc is great, and I mostly followed it. Here's the details of my implementation.
HTML: I wrapped the scrollable area of my content in some divs that iScroll can use:
<div id="wrapper">
<div id="scroller">
... my scrollable content
</div>
</div>
CSS: I used the Modernizr class for "touch" to target my style changes only to touch devices (because I only instantiated iScroll on touch).
.touch #wrapper {
position: absolute;
z-index: 1;
top: 0;
bottom: 0;
left: 0;
right: 0;
overflow: hidden;
}
.touch #scroller {
position: absolute;
z-index: 1;
width: 100%;
}
JS: I included iscroll-probe.js from the iScroll download, and then initialized the scroller as below, where updatePosition is my function that reacts to the new scroll position.
# coffeescript
if Modernizr.touch
myScroller = new IScroll('#wrapper', probeType: 3)
myScroller.on 'scroll', updatePosition
myScroller.on 'scrollEnd', updatePosition
You have to use myScroller to get the current position now, instead of looking at the scroll offset. Here is a function taken from http://markdalgleish.com/presentations/embracingtouch/ (a super helpful article, but a little out of date now)
function getScroll(elem, iscroll) {
var x, y;
if (Modernizr.touch && iscroll) {
x = iscroll.x * -1;
y = iscroll.y * -1;
} else {
x = elem.scrollTop;
y = elem.scrollLeft;
}
return {x: x, y: y};
}
The only other gotcha was occasionally I would lose part of my page that I was trying to scroll to, and it would refuse to scroll. I had to add in some calls to myScroller.refresh() whenever I changed the contents of the #wrapper, and that solved the problem.
EDIT: Another gotcha was that iScroll eats all the "click" events. I turned on the option to have iScroll emit a "tap" event and handled those instead of "click" events. Thankfully I didn't need much clicking in the scroll area, so this wasn't a big deal.
I know this is a jQuery related question, but now days with JS ES6 things are much easier. Since there is no pure javascript answer, I thought I could add a simple pure javascript solution to this, which in my opinion is much cleaner, by using the fetch() API. This a modern way to implements network requests. In your case, since you already have a form element we can simply use it to build our request.
const form = document.forms["orderproductForm"];
const formInputs = form.getElementsByTagName("input");
let formData = new FormData();
for (let input of formInputs) {
formData.append(input.name, input.value);
}
fetch(form.action,
{
method: form.method,
body: formData
})
.then(response => response.json())
.then(data => console.log(data))
.catch(error => console.log(error.message))
.finally(() => console.log("Done"));
In my case, I had accidentally named a folder 'samples '. I couldn't see the space when I did 'ls -la'.
Eventually I realized this when I tried tabbing to autocomplete and saw 'samples\ /'.
To fix this I ran
mv samples\ samples
On MacOS, I have this alias in my bashrc:
alias pycharm="open -a /Applications/PyCharm*.app"
I can use it like this: pycharm <project dir or file>
The advantage of launching PyCharm this way is that you can open the current dir in PyCharm using pycharm . (unlike /Applications/PyCharm*.app/Contents/MacOS/pycharm . which opens the PyCharm application dir instead)
Update: I switched to JetBrains Toolbox to install PyCharm. Finding PyCharm has gotten a bit more complex, but so far I was lucky with this monster:
alias pycharm="open -a \"\$(ls -r /Applications/apps/PyCharm*/*/*/PyCharm*.app | head -n 1 | sed 's/:$//')\""
Since the last update of the xmlhttprequest module was around 2 years ago, in some cases it does not work as expected.
So instead, you can use the xhr2 module. In other words:
var XMLHttpRequest = require("xmlhttprequest").XMLHttpRequest;
var xhr = new XMLHttpRequest();
becomes:
var XMLHttpRequest = require('xhr2');
var xhr = new XMLHttpRequest();
But ... of course, there are more popular modules like Axios, because -for example- uses promises:
// Make a request for a user with a given ID
axios.get('/user?ID=12345').then(function (response) {
console.log(response);
}).catch(function (error) {
console.log(error);
});
An optional parameter is just tagged with an attribute. This attribute tells the compiler to insert the default value for that parameter at the call-site.
The call obj2.TestMethod(); is replaced by obj2.TestMethod(false); when the C# code gets compiled to IL, and not at JIT-time.
So in a way it's always the caller providing the default value with optional parameters. This also has consequences on binary versioning: If you change the default value but don't recompile the calling code it will continue to use the old default value.
On the other hand, this disconnect means you can't always use the concrete class and the interface interchangeably.
You already can't do that if the interface method was implemented explicitly.
You don't have to add a . in getElementsByClassName, i.e.
var multibutton = angular.element(element.getElementsByClassName("multi-files"));
However, when using angular.element, you do have to use jquery style selectors:
angular.element('.multi-files');
should do the trick.
Also, from this documentation "If jQuery is available, angular.element is an alias for the jQuery function. If jQuery is not available, angular.element delegates to Angular's built-in subset of jQuery, called "jQuery lite" or "jqLite.""
Make a list from items in an iterable
It seems best to first generalize all the possible forms rather than giving specific answers to questions. Otherwise, the reader won't know how the answer was determined. Here are a few generalized forms I thought up before I got a headache trying to decide if a final else' clause could be used in the last form.
[expression1(item) for item in iterable]
[expression1(item) if conditional1 for item in iterable]
[expression1(item) if conditional1 else expression2(item) for item in iterable]
[expression1(item) if conditional1 else expression2(item) for item in iterable if conditional2]
The value of item doesn't need to be used in any of the conditional clauses. A conditional3 can be used as a switch to either add or not add a value to the output list.
For example, to create a new list that eliminates empty strings or whitespace strings from the original list of strings:
newlist = [s for s in firstlist if s.strip()]
Sqlite helper class helps us to manage database creation and version management.
SQLiteOpenHelper takes care of all database management activities. To use it,
1.Override onCreate(), onUpgrade() methods of SQLiteOpenHelper. Optionally override onOpen() method.
2.Use this subclass to create either a readable or writable database and use the SQLiteDatabase's four API methods insert(), execSQL(), update(), delete() to create, read, update and delete rows of your table.
Example to create a MyEmployees table and to select and insert records:
public class MyDatabaseHelper extends SQLiteOpenHelper {
private static final String DATABASE_NAME = "DBName";
private static final int DATABASE_VERSION = 2;
// Database creation sql statement
private static final String DATABASE_CREATE = "create table MyEmployees
( _id integer primary key,name text not null);";
public MyDatabaseHelper(Context context) {
super(context, DATABASE_NAME, null, DATABASE_VERSION);
}
// Method is called during creation of the database
@Override
public void onCreate(SQLiteDatabase database) {
database.execSQL(DATABASE_CREATE);
}
// Method is called during an upgrade of the database,
@Override
public void onUpgrade(SQLiteDatabase database,int oldVersion,int newVersion){
Log.w(MyDatabaseHelper.class.getName(),
"Upgrading database from version " + oldVersion + " to "
+ newVersion + ", which will destroy all old data");
database.execSQL("DROP TABLE IF EXISTS MyEmployees");
onCreate(database);
}
}
Now you can use this class as below,
public class MyDB{
private MyDatabaseHelper dbHelper;
private SQLiteDatabase database;
public final static String EMP_TABLE="MyEmployees"; // name of table
public final static String EMP_ID="_id"; // id value for employee
public final static String EMP_NAME="name"; // name of employee
/**
*
* @param context
*/
public MyDB(Context context){
dbHelper = new MyDatabaseHelper(context);
database = dbHelper.getWritableDatabase();
}
public long createRecords(String id, String name){
ContentValues values = new ContentValues();
values.put(EMP_ID, id);
values.put(EMP_NAME, name);
return database.insert(EMP_TABLE, null, values);
}
public Cursor selectRecords() {
String[] cols = new String[] {EMP_ID, EMP_NAME};
Cursor mCursor = database.query(true, EMP_TABLE,cols,null
, null, null, null, null, null);
if (mCursor != null) {
mCursor.moveToFirst();
}
return mCursor; // iterate to get each value.
}
}
Now you can use MyDB class in you activity to have all the database operations. The create records will help you to insert the values similarly you can have your own functions for update and delete.
I encountered the same problem in the code and What I did is I found out all the changes I have made from the last correct compilation. And I have observed one function declaration was without ";" and also it was passing a value and I have declared it to pass nothing "void". this method will surely solve the problem for many.

Set the architecture in build setting to Standard architectures(armv7,armv7s)
iPhone 5S is powered by A7 64bit processor. From apple docs
Xcode can build your app with both 32-bit and 64-bit binaries included. This combined binary requires a minimum deployment target of iOS 7 or later.
Note: A future version of Xcode will let you create a single app that supports the 32-bit runtime on iOS 6 and later, and that supports the 64-bit runtime on iOS 7.
From the documentation what i understood is
Update (Xcode 5.0.1)
In Xcode 5.0.1 they added the support to create 64 bit binary for iOS 5.1.1 onwards.
Xcode 5.0.1 can build your app with both 32-bit and 64-bit binaries included. This combined binary requires a minimum deployment target of iOS 5.1.1 or later. The 64-bit binary runs only on 64-bit devices running iOS 7.0.3 and later.
Update (Xcode 5.1)
Xcode 5.1 made significant change in the architecture section. This answer will be a followup for you.

If you were asking from the perspective of working this out with a running program then you need to look to the java.lang.* package. If you get a Class object, you can use the isAssignableFrom method to check if it is an interface of another Class.
There isn't a simple built in way of searching for these, tools like Eclipse build an index of this information.
If you don't have a specific list of Class objects to test you can look to the ClassLoader object, use the getPackages() method and build your own package hierarchy iterator.
Just a warning though that these methods and classes can be quite slow.
or you can
SELECT
String_to_array(CASE
WHEN <condition 1> THEN a1||','||b1
WHEN <condition 2> THEN a2||','||b2
ELSE a3||','||b3
END, ',') K

Literally all you have to do is:
echo export "JAVA_HOME=\$(/usr/libexec/java_home)" >> ~/.bash_profile
and restart your shell.
If you have multiple JDK versions installed and you want it to be a specific one, you can use the -v flag to java_home like so:
echo export "JAVA_HOME=\$(/usr/libexec/java_home -v 1.7)" >> ~/.bash_profile
In my case, the application was running. Apparently, it needs to be stopped. Weird error message anyways.
You can create multiple canvas elements without appending them into document. These will be your layers:
Then do whatever you want with them and at the end just render their content in proper order at destination canvas using drawImage on context.
Example:
/* using canvas from DOM */
var domCanvas = document.getElementById('some-canvas');
var domContext = domCanvas.getContext('2d');
domContext.fillRect(50,50,150,50);
/* virtual canvase 1 - not appended to the DOM */
var canvas = document.createElement('canvas');
var ctx = canvas.getContext('2d');
ctx.fillStyle = 'blue';
ctx.fillRect(50,50,150,150);
/* virtual canvase 2 - not appended to the DOM */
var canvas2 = document.createElement('canvas')
var ctx2 = canvas2.getContext('2d');
ctx2.fillStyle = 'yellow';
ctx2.fillRect(50,50,100,50)
/* render virtual canvases on DOM canvas */
domContext.drawImage(canvas, 0, 0, 200, 200);
domContext.drawImage(canvas2, 0, 0, 200, 200);
And here is some codepen: https://codepen.io/anon/pen/mQWMMW
You need to tell the Range.RemoveDuplicates method what column to use. Additionally, since you have expressed that you have a header row, you should tell the .RemoveDuplicates method that.
Sub dedupe_abcd()
Dim icol As Long
With Sheets("Sheet1") '<-set this worksheet reference properly!
icol = Application.Match("abcd", .Rows(1), 0)
With .Cells(1, 1).CurrentRegion
.RemoveDuplicates Columns:=icol, Header:=xlYes
End With
End With
End Sub
Your original code seemed to want to remove duplicates from a single column while ignoring surrounding data. That scenario is atypical and I've included the surrounding data so that the .RemoveDuplicates process does not scramble your data. Post back a comment if you truly wanted to isolate the RemoveDuplicates process to a single column.
I'd make a new view class and derive from the existing ProgressBar. Then override the onDraw function. You're going to need to make direct draw calls to the canvas for this, since its so custom- a combination of drawText, drawArc, and drawOval should do it- an oval for the outer ring and empty portions, and an arc for the colored in parts. You may end up needing to override onMeasure and onLayout as well. Then in your xml, reference this view by class name like this when you want to use it.
You should first have some agreed method of ending the thread. For example a running_ valiable that the thread can check and comply with.
Your main thread code should be wrapped in an exception block that catches both ThreadInterruptException and ThreadAbortException that will cleanly tidy up the thread on exit.
In the case of ThreadInterruptException you can check the running_ variable to see if you should continue. In the case of the ThreadAbortException you should tidy up immediately and exit the thread procedure.
The code that tries to stop the thread should do the following:
running_ = false;
threadInstance_.Interrupt();
if(!threadInstance_.Join(2000)) { // or an agreed resonable time
threadInstance_.Abort();
}
$count = DB::table('category_issue')->count();
will give you the number of items.
For more detailed information check Fluent Query Builder section in beautiful Laravel Documentation.
If the case is accessing the IFrame via console, e. g. Chrome Dev Tools then you can just select the context of DOM requests via dropdown (see the picture).
ESLint supports this as of version >= 4:
/*
.eslintrc.js
*/
const ERROR = 2;
const WARN = 1;
module.exports = {
extends: "eslint:recommended",
env: {
es6: true
},
overrides: [
{

"**/*.test.js"
],
env: {
jest: true // now **/*.test.js files' env has both es6 *and* jest
},
// Can't extend in overrides: https://github.com/eslint/eslint/issues/8813

};
Here is a workaround (from another answer on here, vote it up!) for the "extend in overrides" limitation of eslint config :
overrides: [
Object.assign(
{

env: { jest: true },
plugins: [ 'jest' ],
},
require('eslint-plugin-jest').configs.recommended
)

also check this out, for example we wanna count t
echo "test" | awk -v RS='t' 'END{print NR-1}'
or in python
python -c 'print "this is for test".count("t")'
or even better, we can make our script dynamic with awk
echo 'test' | awk '{for (i=1 ; i<=NF ; i++) array[$i]++ } END{ for (char in array) print char,array[char]}' FS=""
in this case output is like this :
e 1
s 1
t 2
You can also try the following project that aims to help use that api. It's here:https://github.com/MathiasSeguy-Android2EE/GDirectionsApiUtils
How it works, definitly simply:
public class MainActivity extends ActionBarActivity implements DCACallBack{
/**
* Get the Google Direction between mDevice location and the touched location using the Walk
* @param point
*/
private void getDirections(LatLng point) {
GDirectionsApiUtils.getDirection(this, mDeviceLatlong, point, GDirectionsApiUtils.MODE_WALKING);
}
/*
* The callback
* When the direction is built from the google server and parsed, this method is called and give you the expected direction
*/
@Override
public void onDirectionLoaded(List<GDirection> directions) {
// Display the direction or use the DirectionsApiUtils
for(GDirection direction:directions) {
Log.e("MainActivity", "onDirectionLoaded : Draw GDirections Called with path " + directions);
GDirectionsApiUtils.drawGDirection(direction, mMap);
}
}
You can do an interactive rebase:
git rebase -i <commit>
This will bring up your default editor. Just delete the line containing the commit you want to remove to delete that commit.
You will, of course, need access to the remote repository to apply this change there too.
See this question: Git: removing selected commits from repository
The main problem in your case would be failure of accessing \\localhost\c$
If you get an error while trying to access the Windows hidden C share (C$):
C:\> net use \\localhost\c$
System error 53 has occurred.
The network path was not found.
You may find the following articles useful: KB254210 and KB951016.
A simple thing is just to make sure your TCP/IP NetBIOS Helper and Server services are running (Start-Run, services.msc) and try again:
C:\> net use \localhost\c$
The command completed successfully.
Of course, your user must be either an administrator or be part of the administrator group.
If it still fails, manually edit the registry (Start-Run, regedit). Browse to:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System
and create a new DWORD value LocalAccountTokenFilterPolicy set to 1
After solving this issue and installing Oracle Database Server, you can disable back your TCP/IP NetBIOS Helper service if you don't need it anymore.
References: http://groglogs.blogspot.ro/2013/11/windows-cannot-access-hidden-c-admin.html
For others:
If you don't have the problem with \\localhost\c$, then you might have the other problem with your username as the others stated (e.g. username with '_' in it):
This will get solved by changing TEMP and TMP environment variables from a command line and then running setup.exe from there.
If this still doesn't work:
Try running setup.exe with "-debug" option and see what happens in there.
You may also want to check what's in the .log files created in your %TEMP% folder (e.g. ssproiut_%number%.log)
You should in fact do both, so that all browsers will find the icon.
Naming the file "favicon.ico" and putting it in the root of your website is the method "discouraged" by W3C:
Method 2 (Discouraged): Putting the favicon at a predefined URI
A second method for specifying a favicon relies on using a predefined URI to identify the image: "/favicon", which is relative to the server root. This method works because some browsers have been programmed to look for favicons using that URI.
W3C - How to add a favicon to your site
So, to cover all situations, I always do that in addition to the recommended method of adding a "rel" attribute and pointing it to the same .ico file.
If you wish to list all tables, you must use:
\dt *.*
to indicate that you want all tables in all schemas. This will include tables in pg_catalog, the system tables, and those in information_schema. There's no built-in way to say "all tables in all user-defined schemas"; you can, however, set your search_path to a list of all schemas of interest before running \dt.
You may want to do this programmatically, in which case psql backslash-commands won't do the job. This is where the INFORMATION_SCHEMA comes to the rescue. To list tables:
SELECT table_name FROM information_schema.tables WHERE table_schema = 'public';
BTW, if you ever want to see what psql is doing in response to a backslash command, run psql with the -E flag. eg:
$ psql -E regress
regress=# \list
********* QUERY **********
SELECT d.datname as "Name",
pg_catalog.pg_get_userbyid(d.datdba) as "Owner",
pg_catalog.pg_encoding_to_char(d.encoding) as "Encoding",
d.datcollate as "Collate",
d.datctype as "Ctype",
pg_catalog.array_to_string(d.datacl, E'\n') AS "Access privileges"
FROM pg_catalog.pg_database d
ORDER BY 1;
**************************
so you can see that psql is searching pg_catalog.pg_database when it gets a list of databases. Similarly, for tables within a given database:
SELECT n.nspname as "Schema",
c.relname as "Name",
CASE c.relkind WHEN 'r' THEN 'table' WHEN 'v' THEN 'view' WHEN 'i' THEN 'index' WHEN 'S' THEN 'sequence' WHEN 's' THEN 'special' WHEN 'f' THEN 'foreign table' END as "Type",
pg_catalog.pg_get_userbyid(c.relowner) as "Owner"
FROM pg_catalog.pg_class c
LEFT JOIN pg_catalog.pg_namespace n ON n.oid = c.relnamespace
WHERE c.relkind IN ('r','')
AND n.nspname <> 'pg_catalog'
AND n.nspname <> 'information_schema'
AND n.nspname !~ '^pg_toast'
AND pg_catalog.pg_table_is_visible(c.oid)
ORDER BY 1,2;
It's preferable to use the SQL-standard, portable INFORMATION_SCHEMA instead of the Pg system catalogs where possible, but sometimes you need Pg-specific information. In those cases it's fine to query the system catalogs directly, and psql -E can be a helpful guide for how to do so.
If you have Perl installed, you could use ack, available at http://beyondgrep.com/.
I have found the following script is very good at maintaining indexes, you can have this scheduled to run nightly or whatever other timeframe you wish.
java.math.BigInteger has a nextProbablePrime() method. Whilst I'm guessing this is meant for cryptography you could use it for you work.
BigInteger prime = BigInteger.valueOf(0);
for (int i = 0; i < n; i++) {
prime = prime.nextProbablePrime();
}
System.out.println(prime.intValue());
You can use the split command with the -b option:
split -b 1024m file.tar.gz
It can be reassembled on a Windows machine using @Joshua's answer.
copy /b file1 + file2 + file3 + file4 filetogether
Edit: As @Charlie stated in the comment below, you might want to set a prefix explicitly because it will use x otherwise, which can be confusing.
split -b 1024m "file.tar.gz" "file.tar.gz.part-"
// Creates files: file.tar.gz.part-aa, file.tar.gz.part-ab, file.tar.gz.part-ac, ...
Edit: Editing the post because question is closed and the most effective solution is very close to the content of this answer:
# create archives
$ tar cz my_large_file_1 my_large_file_2 | split -b 1024MiB - myfiles_split.tgz_
# uncompress
$ cat myfiles_split.tgz_* | tar xz
This solution avoids the need to use an intermediate large file when (de)compressing. Use the tar -C option to use a different directory for the resulting files. btw if the archive consists from only a single file, tar could be avoided and only gzip used:
# create archives
$ gzip -c my_large_file | split -b 1024MiB - myfile_split.gz_
# uncompress
$ cat myfile_split.gz_* | gunzip -c > my_large_file
For windows you can download ported versions of the same commands or use cygwin.
Code generation would be the only other way I can think of. Personally, I'd got with a generally reusable reflection solution (unless that part of the code is absolutely performance-critical). Using JMS sounds like overkill (additional dependency, and that's not even what it's meant for). Besides, it probably uses reflection as well under the hood.
Compare every key in mapB against the counterpart in mapA. Then check if there is any key in mapA not existing in mapB
public boolean mapsAreEqual(Map<String, String> mapA, Map<String, String> mapB) {
try{
for (String k : mapB.keySet())
{
if (!mapA.get(k).equals(mapB.get(k))) {
return false;
}
}
for (String y : mapA.keySet())
{
if (!mapB.containsKey(y)) {
return false;
}
}
} catch (NullPointerException np) {
return false;
}
return true;
}
This code will work. The answer from samplebias is almost correct, but you need a third change:
int addNodeBottom(int val, node *head){
//create new node
node *newNode = (node*)malloc(sizeof(node));
if(newNode == NULL){
fprintf(stderr, "Unable to allocate memory for new node\n");
exit(-1);
}
newNode->value = val;
newNode->next = NULL; // Change 1
//check for first insertion
if(head->next == NULL){
head->next = newNode;
printf("added at beginning\n");
}
else
{
//else loop through the list and find the last
//node, insert next to it
node *current = head;
while (true) { // Change 2
if(current->next == NULL)
{
current->next = newNode;
printf("added later\n");
break; // Change 3
}
current = current->next;
};
}
return 0;
}
Change 1: newNode->next must be set to NULL so we don't insert invalid pointers at the end of the list.
Change 2/3: The loop is changed to an endless loop that will be jumped out with break; when we found the last element. Note how while(current->next != NULL) contradicted if(current->next == NULL) before.
EDIT: Regarding the while loop, this way it is much better:
node *current = head;
while (current->next != NULL) {
current = current->next;
}
current->next = newNode;
printf("added later\n");
How about this:
$(this).css('background-color', '#FFFFFF');

The mipmap folders are for placing your app/launcher icons (which are shown on the homescreen) in only. Any other drawable assets you use should be placed in the relevant drawable folders as before.
According to this Google blogpost:
It’s best practice to place your app icons in mipmap- folders (not the drawable- folders) because they are used at resolutions different from the device’s current density.
When referencing the mipmap- folders ensure you are using the following reference:
android:icon="@mipmap/ic_launcher"
The reason they use a different density is that some launchers actually display the icons larger than they were intended. Because of this, they use the next size up.
You cannot put spaces around the = sign when you do:
export foo=bar
Remove the spaces you have and you should be good to go.
If you type:
export foo = bar
the shell will interpret that as a request to export three names: foo, = and bar. = isn't a valid variable name, so the command fails. The variable name, equals sign and it's value must not be separated by spaces for them to be processed as a simultaneous assignment and export.
For what it's worth, I've had a similar issue - when trying to add a specific allowed origin (not *).
Turns out i had to correct
<AllowedOrigin>http://mydomain:3000/</AllowedOrigin>
to
<AllowedOrigin>http://mydomain:3000</AllowedOrigin>

EntityManager.persist() makes an entity persistent whereas EntityManager.flush() actually runs the query on your database.
So, when you call EntityManager.flush(), queries for inserting/updating/deleting associated entities are executed in the database. Any constraint failures (column width, data types, foreign key) will be known at this time.
The concrete behaviour depends on whether flush-mode is AUTO or COMMIT.
First, I strongly recommend that you rename your variable list to something else. list is the name of the built-in list constructor, and you're hiding its normal function. I will rename list to a in the following.
Python names are references that are bound to objects. That means that unless you create more than one list, whenever you use a it's referring to the same actual list object as last time. So when you call
listoflists.append((a, a[0]))
you can later change a and it changes what the first element of that tuple points to. This does not happen with a[0] because the object (which is an integer) pointed to by a[0] doesn't change (although a[0] points to different objects over the run of your code).
You can create a copy of the whole list a using the list constructor:
listoflists.append((list(a), a[0]))
Or, you can use the slice notation to make a copy:
listoflists.append((a[:], a[0]))
dateTimePicker1.Value = DateTime.Today();
Further to everyone else's answer, you should note that the parameters are optional in C# if your application does not use command line arguments.
This code is perfectly valid:
internal static Program
{
private static void Main()
{
// Get on with it, without any arguments...
}
}
This assumes a few things, that you know what the output file name will be and that your data comes as a string. I'm sure you can modify the following to meet your needs:
// Needed Imports
import java.io.ByteArrayInputStream;
import sun.misc.BASE64Decoder;
def sourceData = 'data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAPAAAADwCAYAAAA+VemSAAAgAEl...==';
// tokenize the data
def parts = sourceData.tokenize(",");
def imageString = parts[1];
// create a buffered image
BufferedImage image = null;
byte[] imageByte;
BASE64Decoder decoder = new BASE64Decoder();
imageByte = decoder.decodeBuffer(imageString);
ByteArrayInputStream bis = new ByteArrayInputStream(imageByte);
image = ImageIO.read(bis);
bis.close();
// write the image to a file
File outputfile = new File("image.png");
ImageIO.write(image, "png", outputfile);
Please note, this is just an example of what parts are involved. I haven't optimized this code at all and it's written off the top of my head.
You do it exactly as you showed with this line:
get.setHeader("Content-Type", "application/x-zip");
So your header is fine and the problem is some other input to the web service. You'll want to debug that on the server side.
Interfaces are only at compile time. This allows only you to check that the expected data received follows a particular structure. For this you can cast your content to this interface:
this.http.get('...')
.map(res => <Product[]>res.json());
See these questions:
You can do something similar with class but the main differences with class are that they are present at runtime (constructor function) and you can define methods in them with processing. But, in this case, you need to instantiate objects to be able to use them:
this.http.get('...')
.map(res => {
var data = res.json();
return data.map(d => {
return new Product(d.productNumber,
d.productName, d.productDescription);
});
});
That's Oracle specific notation for an OUTER JOIN, because the ANSI-89 format (using a comma in the FROM clause to separate table references) didn't standardize OUTER joins.
The query would be re-written in ANSI-92 syntax as:
SELECT ...
FROM a
LEFT JOIN b ON b.id = a.id
This link is pretty good at explaining the difference between JOINs.
It should also be noted that even though the (+) works, Oracle recommends not using it:
Oracle recommends that you use the
FROMclauseOUTER JOINsyntax rather than the Oracle join operator. Outer join queries that use the Oracle join operator(+)are subject to the following rules and restrictions, which do not apply to theFROMclauseOUTER JOINsyntax:
Try:
Install all the required tools and configurations using Microsoft's windows-build-tools by running npm install -g windows-build-tools from an elevated PowerShell (run as Administrator).
You cannot target text nodes with CSS. I'm with you; I wish you could... but you can't :(
If you don't wrap the text node in a <span> like @Jacob suggests, you could instead give the surrounding element padding as opposed to margin:
<p id="theParagraph">The text node!</p>
p#theParagraph
{
border: 1px solid red;
padding-bottom: 10px;
}
With Java 9 you can use IntStream.iterate() with hasNext condition. So you can simplify the code of your method to this:
public static <T> List<List<T>> getBatches(List<T> collection, int batchSize) {
return IntStream.iterate(0, i -> i < collection.size(), i -> i + batchSize)
.mapToObj(i -> collection.subList(i, Math.min(i + batchSize, collection.size())))
.collect(Collectors.toList());
}
Using {0, 1, 2, 3, 4, 5, 6, 7, 8, 9}, the result of getBatches(numbers, 4) will be:
[[0, 1, 2, 3], [4, 5, 6, 7], [8, 9]]

}
The trick is that you have to set it as position:fixed, but only after the user has scrolled past it.
This is done with something like this, attaching a handler to the window.scroll event
// Cache selectors outside callback for performance.
var $window = $(window),
$stickyEl = $('#the-sticky-div'),
elTop = $stickyEl.offset().top;
$window.scroll(function() {
$stickyEl.toggleClass('sticky', $window.scrollTop() > elTop);
});
This simply adds a sticky CSS class when the page has scrolled past it, and removes the class when it's back up.
And the CSS class looks like this
#the-sticky-div.sticky {
position: fixed;
top: 0;
}
EDIT- Modified code to cache jQuery objects, faster now.
The Do/While solution is more elegant, but if you do use just the While solution posted above, without the moveToPosition(-1) you will miss the first element (at least on the Contact query).
I suggest:
if (cursor.getCount() > 0) {
cursor.moveToPosition(-1);
while (cursor.moveToNext()) {
<do stuff>
}
}
I realize this is years late, but I thought I could expand on Conor's answer and add a little bit more to the discussion.
Can someone give me a step by step description of how cookie based authentication works? I've never done anything involving either authentication or cookies. What does the browser need to do? What does the server need to do? In what order? How do we keep things secure?
Step 1: Client > Signing up
Before anything else, the user has to sign up. The client posts a HTTP request to the server containing his/her username and password.
Step 2: Server > Handling sign up
The server receives this request and hashes the password before storing the username and password in your database. This way, if someone gains access to your database they won't see your users' actual passwords.
Step 3: Client > User login
Now your user logs in. He/she provides their username/password and again, this is posted as a HTTP request to the server.
Step 4: Server > Validating login
The server looks up the username in the database, hashes the supplied login password, and compares it to the previously hashed password in the database. If it doesn't check out, we may deny them access by sending a 401 status code and ending the request.
Step 5: Server > Generating access token
If everything checks out, we're going to create an access token, which uniquely identifies the user's session. Still in the server, we do two things with the access token:
Henceforth, the cookies will be attached to every request (and response) made between the client and server.
Step 6: Client > Making page requests
Back on the client side, we are now logged in. Every time the client makes a request for a page that requires authorization (i.e. they need to be logged in), the server obtains the access token from the cookie and checks it against the one in the database associated with that user. If it checks out, access is granted.
This should get you started. Be sure to clear the cookies upon logout!
You'd need to remove the blank table cell element entirely, and change the colspan attribute on another cell in the row to encompass the released space, e.g.:
refToCellToRemove.remove();
refTocellToExpand.colspan = 4;
Note that setting it via setAttribute (which would otherwise be correct) will not work properly on IE.
Beware: IE does some very strange table layout things when you muck about with colspans dynamically. If you can avoid it, I would.
here whatever we write in between the pre tags it will be interpreted same as html pre tag
ex:
<?php
echo '<pre>';
echo '
code here
will be displayed
as it
is
namaste
';
echo "this line get printed in new line";
echo "</pre>";
echo "Now pre ended:";
echo "this line gets joined to above line";
?>
and content b/w 's font also changes.
Just to include the latest update (UPDATE 4) in @Arhimed 's immaculate answer in the very good summary of @sulai:

}
I'm not sure how much of your "slowness" will be due to the loop you're doing to find entries with particular attribute values, but you can remove this loop by being more specific with your filter. Try this page for some guidance ... Search Filter Syntax
You can use: Object.keys(obj)
Example:
var dictionary = {
"cats": [1, 2, 37, 38, 40, 32, 33, 35, 39, 36],
"dogs": [4, 5, 6, 3, 2]
};
// Get the keys
var keys = Object.keys(dictionary);
console.log(keys);See reference below for browser support. It is supported in Firefox 4.20, Chrome 5, and Internet Explorer 9. Object.keys() contains a code snippet that you can add if Object.keys() is not supported in your browser.
Please check the configuration file in the project, set ID and password there, so that you execute the package

you can use "__range" for example :
from datetime import datetime
start_date=datetime(2009, 12, 30)
end_end=datetime(2020,12,30)
Sample.objects.filter(date__range=[start_date,end_date])
Even easier

As said by jensgram, IE6 does not support attribute selector. You could add a class="disabled" to select the disabled inputs so that this can work in IE6.
Frankly the errors are really hard to see, especially if only one character is "underwaved" in a sea of Java code. I used the instructions above to make the background an orangey-red color and things are much more obvious.
This worked for me:

BTW, if you want to use ALT+some_key and your terminal (urxvt does this) refuses to comply, you should enter something like this in your .vimrc:
" For moving lines (^] is a special character; use <M-k> and <M-j> if it works)
nnoremap ^]k mz:m-2<CR>`z==
inoremap ^]j <Esc>:m+<CR>==gi
inoremap ^]k <Esc>:m-2<CR>==gi
vnoremap ^]j :m'>+<CR>gv=`<my`>mzgv`yo`z
nnoremap ^]j mz:m+<CR>`z==
vnoremap ^]k :m'<-2<CR>gv=`>my`<mzgv`yo`z
where ^] is a single character that represents the ALT key. To input that character, use C+v, Esc in Vim (C+q, Esc on Windows).
In answer to the question in how to write to a file in PHP you can use the following as an example:
$fp = fopen ($filename, "a"); # a = append to the file. w = write to the file (create new if doesn't exist)
if ($fp) {
fwrite ($fp, $text); //$text is what you are writing to the file
fclose ($fp);
$writeSuccess = "Yes";
#echo ("File written");
}
else {
$writeSuccess = "No";
#echo ("File was not written");
}
#include <algorithm>
#include <iostream>
template <typename T>
inline const T&
max_of(const T& a, const T& b) {
return std::max(a, b);
}
template <typename T, typename ...Args>
inline const T&
max_of(const T& a, const T& b, const Args& ...args) {
return max_of(std::max(a, b), args...);
}
int main() {
std::cout << max_of(1, 2, 3, 4, 5) << std::endl;
// Or just use the std library:
std::cout << std::max({1, 2, 3, 4, 5}) << std::endl;
return 0;
}
It works well in combination with zero-based indexing and len(). For example, if you have 10 items in a list x, they are numbered 0-9. range(len(x)) gives you 0-9.
Of course, people will tell you it's more Pythonic to do for item in x or for index, item in enumerate(x) rather than for i in range(len(x)).
Slicing works that way too: foo[1:4] is items 1-3 of foo (keeping in mind that item 1 is actually the second item due to the zero-based indexing). For consistency, they should both work the same way.
I think of it as: "the first number you want, followed by the first number you don't want." If you want 1-10, the first number you don't want is 11, so it's range(1, 11).
If it becomes cumbersome in a particular application, it's easy enough to write a little helper function that adds 1 to the ending index and calls range().
Try casting your column to a numeric like:
SELECT ROUND(cast(some_column as numeric),2) FROM table
Very simply, you can rename your Python script to "pythonscript.cgi". Post that in your cgi-bin directory, add the appropriate permissions and browse to it.
This is a great link you can start with.
Hope that helps.

Look at stat for checking if the directory exists,
And mkdir, to create a directory.
#include <sys/types.h>
#include <sys/stat.h>
#include <unistd.h>
struct stat st = {0};
if (stat("/some/directory", &st) == -1) {
mkdir("/some/directory", 0700);
}
You can see the manual of these functions with the man 2 stat and man 2 mkdir commands.
Just to be clear, when you use xcopy /s c:\source d:\target, put "" around the c:\source and d:\target,otherwise you get error.
ie if there are spaces in the path ie if you have:
"C:\Some Folder\*.txt"
but not required if you have:
C:\SomeFolder\*.txt
I suggest that someone needs to make empty plot in order to add some graphics on it later. So, using
plot(1, type="n", xlab="", ylab="", xlim=c(0, 10), ylim=c(0, 10))
you can specify the axes limits of your graphic.
select myfield, CAST(myfield as varbinary(max)) ...

}
contentType is the type of data you're sending, so application/json; charset=utf-8 is a common one, as is application/x-www-form-urlencoded; charset=UTF-8, which is the default.
dataType is what you're expecting back from the server: json, html, text, etc. jQuery will use this to figure out how to populate the success function's parameter.
If you're posting something like:
{"name":"John Doe"}
and expecting back:
{"success":true}
Then you should have:
var data = {"name":"John Doe"}
$.ajax({
dataType : "json",
contentType: "application/json; charset=utf-8",
data : JSON.stringify(data),
success : function(result) {
alert(result.success); // result is an object which is created from the returned JSON
},
});
If you're expecting the following:
<div>SUCCESS!!!</div>
Then you should do:
var data = {"name":"John Doe"}
$.ajax({
dataType : "html",
contentType: "application/json; charset=utf-8",
data : JSON.stringify(data),
success : function(result) {
jQuery("#someContainer").html(result); // result is the HTML text
},
});
One more - if you want to post:
name=John&age=34
Then don't stringify the data, and do:
var data = {"name":"John", "age": 34}
$.ajax({
dataType : "html",
contentType: "application/x-www-form-urlencoded; charset=UTF-8", // this is the default value, so it's optional
data : data,
success : function(result) {
jQuery("#someContainer").html(result); // result is the HTML text
},
});
Varargs will work too!
Stream.of(T... values).collect(Collectors.toSet());
$("#search").on("keyup", function() {
var value = $(this).val().toLowerCase();
$("tbody tr").filter(function() {
$(this).toggle($(this).text().toLowerCase().indexOf(value) > -1)
});
});
Assumption there is a one table with a tbody. you can also search with find or if the table has an ID you can use the id
Here is the example for having one or more checkboxes value. If you have two or more checkboxes and need values then this would really help.

You can do something like the following:
vector<int*> iarray;
int default_item = 0; // for handling out-of-range exception
int& get_item_as_ref(unsigned int idx) {
// handling out-of-range exception
if(idx >= iarray.size())
return default_item;
return reinterpret_cast<int&>(*iarray[idx]);
}

There are couple of ways to establish HHTP connection and fetch data from a RESTFULL web service. The most recent one is GSON. But before you proceed to GSON you must have some idea of the most traditional way of creating an HTTP Client and perform data communication with a remote server. I have mentioned both the methods to send POST & GET requests using HTTPClient.
/**
* This method is used to process GET requests to the server.
*
* @param url
* @return String
* @throws IOException
*/
public static String connect(String url) throws IOException {
HttpGet httpget = new HttpGet(url);
HttpResponse response;
HttpParams httpParameters = new BasicHttpParams();
// Set the timeout in milliseconds until a connection is established.
// The default value is zero, that means the timeout is not used.
int timeoutConnection = 60*1000;
HttpConnectionParams.setConnectionTimeout(httpParameters, timeoutConnection);
// Set the default socket timeout (SO_TIMEOUT)
// in milliseconds which is the timeout for waiting for data.
int timeoutSocket = 60*1000;
HttpConnectionParams.setSoTimeout(httpParameters, timeoutSocket);
HttpClient httpclient = new DefaultHttpClient(httpParameters);
try {
response = httpclient.execute(httpget);
HttpEntity entity = response.getEntity();
if (entity != null) {
InputStream instream = entity.getContent();
result = convertStreamToString(instream);
//instream.close();
}
}
catch (ClientProtocolException e) {
Utilities.showDLog("connect","ClientProtocolException:-"+e);
} catch (IOException e) {
Utilities.showDLog("connect","IOException:-"+e);
}
return result;
}
/**
* This method is used to send POST requests to the server.
*
* @param URL
* @param paramenter
* @return result of server response
*/
static public String postHTPPRequest(String URL, String paramenter) {
HttpParams httpParameters = new BasicHttpParams();
// Set the timeout in milliseconds until a connection is established.
// The default value is zero, that means the timeout is not used.
int timeoutConnection = 60*1000;
HttpConnectionParams.setConnectionTimeout(httpParameters, timeoutConnection);
// Set the default socket timeout (SO_TIMEOUT)
// in milliseconds which is the timeout for waiting for data.
int timeoutSocket = 60*1000;
HttpConnectionParams.setSoTimeout(httpParameters, timeoutSocket);
HttpClient httpclient = new DefaultHttpClient(httpParameters);
HttpPost httppost = new HttpPost(URL);
httppost.setHeader("Content-Type", "application/json");
try {
if (paramenter != null) {
StringEntity tmp = null;
tmp = new StringEntity(paramenter, "UTF-8");
httppost.setEntity(tmp);
}
HttpResponse httpResponse = null;
httpResponse = httpclient.execute(httppost);
HttpEntity entity = httpResponse.getEntity();
if (entity != null) {
InputStream input = null;
input = entity.getContent();
String res = convertStreamToString(input);
return res;
}
}
catch (Exception e) {
System.out.print(e.toString());
}
return null;
}
In addition to Greg's answer, I would recommend to set the constructor private so that it is impossible to instantiate the class.
So in my humble opinion this is a more complete example based on Greg's one:
<?php
class Hello
{
/**
* Construct won't be called inside this class and is uncallable from
* the outside. This prevents instantiating this class.
* This is by purpose, because we want a static class.
*/
private function __construct() {}
private static $greeting = 'Hello';
private static $initialized = false;
private static function initialize()
{
if (self::$initialized)
return;
self::$greeting .= ' There!';
self::$initialized = true;
}
public static function greet()
{
self::initialize();
echo self::$greeting;
}
}
Hello::greet(); // Hello There!
?>
Check out DecimalFormat: http://docs.oracle.com/javase/6/docs/api/java/text/DecimalFormat.html
You'll do something like:
new DecimalFormat("$#.00").format(shippingCost);
Or since you're working with currency, you could see how NumberFormat.getCurrencyInstance() works for you.
Team Foundation Server 2015 (on-premises) and Visual Studio Team Services (cloud version) include built-in support for searching across all your code and work items.

The necessary method is Mockito#verify:
public static <T> T verify(T mock,
VerificationMode mode)
mock is your mocked object and mode is the VerificationMode that describes how the mock should be verified. Possible modes are:
verify(mock, times(5)).someMethod("was called five times");
verify(mock, never()).someMethod("was never called");
verify(mock, atLeastOnce()).someMethod("was called at least once");
verify(mock, atLeast(2)).someMethod("was called at least twice");
verify(mock, atMost(3)).someMethod("was called at most 3 times");
verify(mock, atLeast(0)).someMethod("was called any number of times"); // useful with captors
verify(mock, only()).someMethod("no other method has been called on the mock");
You'll need these static imports from the Mockito class in order to use the verify method and these verification modes:
import static org.mockito.Mockito.atLeast;
import static org.mockito.Mockito.atLeastOnce;
import static org.mockito.Mockito.atMost;
import static org.mockito.Mockito.never;
import static org.mockito.Mockito.only;
import static org.mockito.Mockito.times;
import static org.mockito.Mockito.verify;
So in your case the correct syntax will be:
Mockito.verify(mock, times(4)).send()
This verifies that the method send was called 4 times on the mocked object. It will fail if it was called less or more than 4 times.
If you just want to check, if the method has been called once, then you don't need to pass a VerificationMode. A simple
verify(mock).someMethod("was called once");
would be enough. It internally uses verify(mock, times(1)).someMethod("was called once");.
It is possible to have multiple verification calls on the same mock to achieve a "between" verification. Mockito doesn't support something like this verify(mock, between(4,6)).someMethod("was called between 4 and 6 times");, but we can write
verify(mock, atLeast(4)).someMethod("was called at least four times ...");
verify(mock, atMost(6)).someMethod("... and not more than six times");
instead, to get the same behaviour. The bounds are included, so the test case is green when the method was called 4, 5 or 6 times.
Beside the excellent answer of KLE, we can also make something more flexible:
boolean b = string.equalsIgnoreCase("true") || string.equalsIgnoreCase("t") ||
string.equalsIgnoreCase("yes") || string.equalsIgnoreCase("y") ||
string.equalsIgnoreCase("sure") || string.equalsIgnoreCase("aye") ||
string.equalsIgnoreCase("oui") || string.equalsIgnoreCase("vrai");
(inspired by zlajo's answer... :-))
If you're using github, they have a very nice tutorial that explains it more clearly (at least to me).
Java 9 offers a Matcher.replaceAll() that accepts a replacement function:

My issue was also the firewall. I'm using a Linux server with WHM/cPanel. Adding my IP to the quick allow solved my issue. I hadn't updated Filezilla and I don't think there were any changes to the server that should have caused it. However, I did move and my IP changed so maybe that was the problem. Good luck to everyone else with this insanely annoying issue.

This website has a concise tutorial on how to use SQL Server Management Studio. As you will see you can open a "Query Window", paste your script and run it. It does not allow you to execute scripts by using the file path. However, you can do this easily by using the command line (cmd.exe):
sqlcmd -S .\SQLExpress -i SqlScript.sql
Where SqlScript.sql is the script file name located at the current directory. See this Microsoft page for more examples
For System.Timers.Timer, according to MSDN documentation, http://msdn.microsoft.com/en-us/library/system.timers.timer.enabled.aspx:
If the interval is set after the Timer has started, the count is reset. For example, if you set the interval to 5 seconds and then set the Enabled property to true, the count starts at the time Enabled is set. If you reset the interval to 10 seconds when count is 3 seconds, the Elapsed event is raised for the first time 13 seconds after Enabled was set to true.
So,
const double TIMEOUT = 5000; // milliseconds
aTimer = new System.Timers.Timer(TIMEOUT);
aTimer.Start(); // timer start running
:
:
aTimer.Interval = TIMEOUT; // restart the timer

You can close a figure by calling matplotlib.pyplot.close, for example:
from numpy import *
import matplotlib.pyplot as plt
from scipy import *
t = linspace(0, 0.1,1000)
w = 60*2*pi
fig = plt.figure()
plt.plot(t,cos(w*t))
plt.plot(t,cos(w*t-2*pi/3))
plt.plot(t,cos(w*t-4*pi/3))
plt.show()
plt.close(fig)
You can also close all open figures by calling matplotlib.pyplot.close("all")
Yet another way to remove an element(s) from a list by index.
a = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
# remove the element at index 3
a[3:4] = []
# a is now [0, 1, 2, 4, 5, 6, 7, 8, 9]
# remove the elements from index 3 to index 6
a[3:7] = []
# a is now [0, 1, 2, 7, 8, 9]
a[x:y] points to the elements from index x to y-1. When we declare that portion of the list as an empty list ([]), those elements are removed.
int[] array = { 1, 3, 5 };
var lastItem = array[^1]; // 5
For Python 3.3 and later time.process_time() is very nice:

The xmlhttp request method is not valid for the files on local disk because the browser security does not allow us to do so.But we can override the browser security by creating a shortcut->right click->properties In target "... browser location path.exe" append --allow-file-access-from-files.This is tested on chrome,however care should be taken that all browser windows should be closed and the code should be run from the browser opened via this shortcut.
The on-heap store refers to objects that will be present in the Java heap (and also subject to GC). On the other hand, the off-heap store refers to (serialized) objects that are managed by EHCache, but stored outside the heap (and also not subject to GC). As the off-heap store continues to be managed in memory, it is slightly slower than the on-heap store, but still faster than the disk store.
The internal details involved in management and usage of the off-heap store aren't very evident in the link posted in the question, so it would be wise to check out the details of Terracotta BigMemory, which is used to manage the off-disk store. BigMemory (the off-heap store) is to be used to avoid the overhead of GC on a heap that is several Megabytes or Gigabytes large. BigMemory uses the memory address space of the JVM process, via direct ByteBuffers that are not subject to GC unlike other native Java objects.
The second answer provided by nickf is very clever. However, it only works for a character length of the target sub-string of 1 and ignores spaces. Specifically, there were two leading spaces in my data, which SQL helpfully removes (I didn't know this) when all the characters on the right-hand-side are removed. Which meant that
" John Smith"
generated 12 using Nickf's method, whereas:
" Joe Bloggs, John Smith"
generated 10, and
" Joe Bloggs, John Smith, John Smith"
Generated 20.
I've therefore modified the solution slightly to the following, which works for me:
Select (len(replace(Sales_Reps,' ',''))- len(replace((replace(Sales_Reps, ' ','')),'JohnSmith','')))/9 as Count_JS
I'm sure someone can think of a better way of doing it!
I'm using EasyPHP in making my Thesis about Content Management System. So far, this tool is very good and easy to use.
You can add them like this
Route::get('company/{name}', 'PublicareaController@companydetails');
The safest way is to rely on the browser TextNode to correctly escape content. Here's an example:
function stripHTML(dirtyString) {_x000D_
var container = document.createElement('div');_x000D_
var text = document.createTextNode(dirtyString);_x000D_
container.appendChild(text);_x000D_
return container.innerHTML; // innerHTML will be a xss safe string_x000D_
}_x000D_
_x000D_
document.write( stripHTML('<p>some <span>content</span></p>') );_x000D_
document.write( stripHTML('<script><p>some <span>content</span></p>') );The thing to remember here is that the browser escape the special characters of TextNodes when we access the html strings (innerHTML, outerHTML). By comparison, accessing text values (innerText, textContent) will yield raw strings, meaning they're unsafe and could contains XSS.
If you use jQuery, then using .text() is safe and backward compatible. See the other answers to this question.
The simplest way in pure JavaScript if you work with browsers <= Internet Explorer 8 is:
string.replace(/(<([^>]+)>)/ig,"");
But there's some issue with parsing HTML with regex so this won't provide very good security. Also, this only takes care of HTML characters, so it is not totally xss-safe.

If use for native Android, check your AndroidMaifest.xml file:
<meta-data
android:name="onesignal_google_project_number"
android:value="str:1234567890" />
<!-- its is correct. -->
instead
<meta-data
android:name="onesignal_google_project_number"
android:value="@string/google_project_number" />
Hope it helps!!
Python, as a dynamic language, cannot be "compiled" into machine code statically, like C or COBOL can. You'll always need an interpreter to execute the code, which, by definition in the language, is a dynamic operation.
You can "translate" source code in bytecode, which is just an intermediate process that the interpreter does to speed up the load of the code, It converts text files, with comments, blank spaces, words like 'if', 'def', 'in', etc in binary code, but the operations behind are exactly the same, in Python, not in machine code or any other language. This is what it's stored in .pyc files and it's also portable between architectures.
Probably what you need it's not "compile" the code (which it's not possible) but to "embed" an interpreter (in the right architecture) with the code to allow running the code without an external installation of the interpreter. To do that, you can use all those tools like py2exe or cx_Freeze.
Maybe I'm being a little pedantic on this :-P
This feature is called XML Inclusions (XInclude). Some examples:
change it to Console (/SUBSYSTEM:CONSOLE) it will work
It's really easy to do this, simply send the file via an XHR request inside of the file input's onchange handler.
<input id="myFileInput" type="file" accept="image/*;capture=camera">
var myInput = document.getElementById('myFileInput');
function sendPic() {
var file = myInput.files[0];
// Send file here either by adding it to a `FormData` object
// and sending that via XHR, or by simply passing the file into
// the `send` method of an XHR instance.
}
myInput.addEventListener('change', sendPic, false);
Didn't see an example of both in one query. So this example might help.
/**
INTERNATIONAL_ORDERS - table of orders by company by location by day
companyId, country, city, total, date
**/
SELECT country, city, sum(total) totalCityOrders
FROM INTERNATIONAL_ORDERS with (nolock)
WHERE companyId = 884501253109
GROUP BY country, city
HAVING country = 'MX'
ORDER BY sum(total) DESC
This filters the table first by the companyId, then groups it (by country and city) and additionally filters it down to just city aggregations of Mexico. The companyId was not needed in the aggregation but we were able to use WHERE to filter out just the rows we wanted before using GROUP BY.
The simplest way is create a static folder inside the main project folder. Static folder containing .css files.
main folder
/Main Folder
/Main Folder/templates/foo.html
/Main Folder/static/foo.css
/Main Folder/application.py(flask script)
Image of main folder containing static and templates folders and flask script
flask
from flask import Flask, render_template
app = Flask(__name__)
@app.route("/")
def login():
return render_template("login.html")

I made some changes in above code to look for a location fix by both GPS and Network for about 5sec and give me the best known location out of it.
public class LocationService implements LocationListener {
boolean isGPSEnabled = false;
boolean isNetworkEnabled = false;
boolean canGetLocation = false;
final static long MIN_TIME_INTERVAL = 60 * 1000L;
Location location;
// The minimum distance to change Updates in meters
private static final long MIN_DISTANCE_CHANGE_FOR_UPDATES = 0; // 10
// The minimum time between updates in milliseconds
private static final long MIN_TIME_BW_UPDATES = 1; // 1 minute
protected LocationManager locationManager;
private CountDownTimer timer = new CountDownTimer(5 * 1000, 1000) {
public void onTick(long millisUntilFinished) {
}
public void onFinish() {
stopUsingGPS();
}
};
public LocationService() {
super(R.id.gps_service_id);
}
public void start() {
if (Utils.isNetworkAvailable(context)) {
try {
timer.start();
locationManager = (LocationManager) context
.getSystemService(Context.LOCATION_SERVICE);
isGPSEnabled = locationManager
.isProviderEnabled(LocationManager.GPS_PROVIDER);
isNetworkEnabled = locationManager
.isProviderEnabled(LocationManager.NETWORK_PROVIDER);
this.canGetLocation = true;
if (isNetworkEnabled) {
locationManager.requestLocationUpdates(
LocationManager.NETWORK_PROVIDER,
MIN_TIME_BW_UPDATES,
MIN_DISTANCE_CHANGE_FOR_UPDATES, this);
Log.d("Network", "Network");
if (locationManager != null) {
Location tempLocation = locationManager
.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
if (tempLocation != null
&& isBetterLocation(tempLocation,
location))
location = tempLocation;
}
}
if (isGPSEnabled) {
locationManager.requestSingleUpdate(
LocationManager.GPS_PROVIDER, this, null);
locationManager.requestLocationUpdates(
LocationManager.GPS_PROVIDER, MIN_TIME_BW_UPDATES,
MIN_DISTANCE_CHANGE_FOR_UPDATES, this);
Log.d("GPS Enabled", "GPS Enabled");
if (locationManager != null) {
Location tempLocation = locationManager
.getLastKnownLocation(LocationManager.GPS_PROVIDER);
if (tempLocation != null
&& isBetterLocation(tempLocation,
location))
location = tempLocation;
}
}
} catch (Exception e) {
onTaskError(e.getMessage());
e.printStackTrace();
}
} else {
onOfflineResponse(requestData);
}
}
public void stopUsingGPS() {
if (locationManager != null) {
locationManager.removeUpdates(LocationService.this);
}
}
public boolean canGetLocation() {
locationManager = (LocationManager) context
.getSystemService(Context.LOCATION_SERVICE);
isGPSEnabled = locationManager
.isProviderEnabled(LocationManager.GPS_PROVIDER);
// getting network status
isNetworkEnabled = locationManager
.isProviderEnabled(LocationManager.NETWORK_PROVIDER);
return isGPSEnabled || isNetworkEnabled;
}
@Override
public void onLocationChanged(Location location) {
if (location != null
&& isBetterLocation(location, this.location)) {
this.location = location;
}
}
@Override
public void onProviderDisabled(String provider) {
}
@Override
public void onProviderEnabled(String provider) {
}
@Override
public void onStatusChanged(String provider, int status, Bundle extras) {
}
@Override
public Object getResponseObject(Object location) {
return location;
}
public static boolean isBetterLocation(Location location,
Location currentBestLocation) {
if (currentBestLocation == null) {
// A new location is always better than no location
return true;
}
// Check whether the new location fix is newer or older
long timeDelta = location.getTime() - currentBestLocation.getTime();
boolean isSignificantlyNewer = timeDelta > MIN_TIME_INTERVAL;
boolean isSignificantlyOlder = timeDelta < -MIN_TIME_INTERVAL;
boolean isNewer = timeDelta > 0;
// If it's been more than two minutes since the current location,
// use the new location
// because the user has likely moved
if (isSignificantlyNewer) {
return true;
// If the new location is more than two minutes older, it must
// be worse
} else if (isSignificantlyOlder) {
return false;
}
// Check whether the new location fix is more or less accurate
int accuracyDelta = (int) (location.getAccuracy() - currentBestLocation
.getAccuracy());
boolean isLessAccurate = accuracyDelta > 0;
boolean isMoreAccurate = accuracyDelta < 0;
boolean isSignificantlyLessAccurate = accuracyDelta > 200;
// Check if the old and new location are from the same provider
boolean isFromSameProvider = isSameProvider(location.getProvider(),
currentBestLocation.getProvider());
// Determine location quality using a combination of timeliness and
// accuracy
if (isMoreAccurate) {
return true;
} else if (isNewer && !isLessAccurate) {
return true;
} else if (isNewer && !isSignificantlyLessAccurate
&& isFromSameProvider) {
return true;
}
return false;
}
}
In the above class, I am registering a location listener for both GPS and network, so an onLocationChanged call back can be called by either or both of them multiple times and we just compare the new location fix with the one we already have and keep the best one.
Full sync has few tasks:
git reset HEAD --hard
git clean -f
git pull origin master
Or else, what I prefer is that, I may create a new branch with the latest from the remote using:
git checkout origin/master -b <new branch name>
origin is my remote repository reference, and master is my considered branch name. These may different from yours.
In Notepad++ v. 6.4.1 is this possibility in:Settings->Preferences->Auto-Completion and there check Enable auto-completion on each input.
For auto-complete in code press Ctrl + Enter.
putting a quick example, should be a sufficient starting point
Code in Form A
public event EventHandler<EventArgs> RowAdded;
private void btnRowAdded_Click(object sender, EventArgs e)
{
// insert data
// if successful raise event
OnRowAddedEvent();
}
private void OnRowAddedEvent()
{
var listener = RowAdded;
if (listener != null)
listener(this, EventArgs.Empty);
}
Code in Form B
private void button1_Click(object sender, EventArgs e)
{
var frm = new Form2();
frm.RowAdded += new EventHandler<EventArgs>(frm_RowAdded);
frm.Show();
}
void frm_RowAdded(object sender, EventArgs e)
{
// retrieve data again
}
You can even consider creating your own EventArgs class that can contain the newly added data. You can then use this to directly add the data to a new row in DatagridView

Similarily, you can set it in windows environment variables. for example, in Win7
Right click Start-->Computer then Properties-->Advanced System Setting --> Advanced -->Environment Variables in the user variables, click classPath, and Edit and add the full path of jars at the end. voila
