This will replace backslashes with forward slashes in the string:
source = source.replace('\\','/');
You have to first escape the backslash because it's a literal (yielding \\
), and then escape it again because of the regular expression (yielding \\\\
). So, Try:
s.replaceAll("'", "\\\\'");
output:
You\'ll be totally awesome, I\'m really terrible
That should work, but don't kill yourself trying to figure it out. Just use 2 passes.
str = str.replaceAll("(\r\n)", "<br />");
str = str.replaceAll("(\n)", "<br />");
Disclaimer: this is not very efficient.
To avoid this sort of trouble, you can use replace
(which takes a plain string) instead of replaceAll
(which takes a regular expression). You will still need to escape backslashes, but not in the wild ways required with regular expressions.
Check the manual for mysql_fetch_object()
. It returns an object, not an array of objects.
I'm guessing you want something like this
$results = mysql_query("SELECT * FROM sidemenu WHERE `menu_id`='".$menu."' ORDER BY `id` ASC LIMIT 1", $con);
$sidemenus = array();
while ($sidemenu = mysql_fetch_object($results)) {
$sidemenus[] = $sidemenu;
}
Might I suggest you have a look at PDO. PDOStatement::fetchAll(PDO::FETCH_OBJ)
does what you assumed mysql_fetch_object()
to do
you can set it in .bashrc
PATH=$PATH:/opt/ActiveTcl-8.5/bin;export PATH;
Implement division without divison operator: You will need to include subtraction. But then it is just like you do it by hand (only in the basis of 2). The appended code provides a short function that does exactly this.
uint32_t udiv32(uint32_t n, uint32_t d) {
// n is dividend, d is divisor
// store the result in q: q = n / d
uint32_t q = 0;
// as long as the divisor fits into the remainder there is something to do
while (n >= d) {
uint32_t i = 0, d_t = d;
// determine to which power of two the divisor still fits the dividend
//
// i.e.: we intend to subtract the divisor multiplied by powers of two
// which in turn gives us a one in the binary representation
// of the result
while (n >= (d_t << 1) && ++i)
d_t <<= 1;
// set the corresponding bit in the result
q |= 1 << i;
// subtract the multiple of the divisor to be left with the remainder
n -= d_t;
// repeat until the divisor does not fit into the remainder anymore
}
return q;
}
It is impossible to safely escape a string without a DB connection. mysql_real_escape_string()
and prepared statements need a connection to the database so that they can escape the string using the appropriate character set - otherwise SQL injection attacks are still possible using multi-byte characters.
If you are only testing, then you may as well use mysql_escape_string()
, it's not 100% guaranteed against SQL injection attacks, but it's impossible to build anything safer without a DB connection.
L
: long i = 12345678910L;
.BTW: it doesn't have to be an upper case L, but lower case is confused with 1
many times :).
The following command will save the SSH key on the clipboard. You only need to paste at the desired location.

Based on your previous questions, I suppose you want to run JavaScript snippets from Java's WebDriver
. Please correct me if I'm wrong.
The WebDriverJs
is actually "just" another WebDriver
language binding (you can write your tests in Java, C#, Ruby, Python, JS and possibly even more languages as of now). This one, particularly, is JavaScript, and allows you therefore to write tests in JavaScript.
If you want to run JavaScript code in Java WebDriver
, do this instead:
WebDriver driver = new AnyDriverYouWant();
if (driver instanceof JavascriptExecutor) {
((JavascriptExecutor)driver).executeScript("yourScript();");
} else {
throw new IllegalStateException("This driver does not support JavaScript!");
}
I like to do this, also:
WebDriver driver = new AnyDriverYouWant();
JavascriptExecutor js;
if (driver instanceof JavascriptExecutor) {
js = (JavascriptExecutor)driver;
} // else throw...
// later on...
js.executeScript("return document.getElementById('someId');");
You can find more documentation on this here, in the documenation, or, preferably, in the JavaDocs of JavascriptExecutor
.
The executeScript()
takes function calls and raw JS, too. You can return
a value from it and you can pass lots of complicated arguments to it, some random examples:
// returns the right WebElement
// it's the same as driver.findElement(By.id("someId"))
js.executeScript("return document.getElementById('someId');");
// draws a border around WebElement
WebElement element = driver.findElement(By.anything("tada"));
js.executeScript("arguments[0].style.border='3px solid red'", element);
// changes all input elements on the page to radio buttons
js.executeScript(
"var inputs = document.getElementsByTagName('input');" +
"for(var i = 0; i < inputs.length; i++) { " +
" inputs[i].type = 'radio';" +
"}" );
It's very simple. Suppose that you have made changes to your Branch A which resides on both place locally and remotely but you want to push these changes to Branch B which doesn't exist anywhere.
Step-01: create and switch to the new branch B
git checkout -b B
Step-02: Add changes in the new local branch
git add . //or specific file(s)
Step-03: Commit the changes
git commit -m "commit_message"
Step-04: Push changes to the new branch B. The below command will create a new branch B as well remotely
git push origin B
Now, you can verify from bitbucket that the branch B will have one more commit than branch A. And when you will checkout the branch A these changes won't be there as these have been pushed into the branch B.
Note: If you have commited your changes into the branch A and after that you want to shift those changes into the new branch B then you will have to reset those changes first. #HappyLearning
You are indeed passing the first data item to the each function.
Pass data.programs to the each function instead. Change the code to as below:
<script>
$(document).ready(function() {
var data = { "programs": [ { "name":"zonealarm", "price":"500" }, { "name":"kaspersky", "price":"200" } ] };
$.each(data.programs, function(key,val) {
alert(key+val);
});
});
</script>
The /P
switch allows you to set the value of a variable to a line of input entered by the user. Displays the specified promptString before reading the line of input. The promptString can be empty.
Two ways I've used it... first:
SET /P variable=
When batch file reaches this point (when left blank) it will halt and wait for user input. Input then becomes variable.
And second:
SET /P variable=<%temp%\filename.txt
Will set variable to contents (the first line) of the txt file. This method won't work unless the /P
is included. Both tested on Windows 8.1 Pro, but it's the same on 7 and 10.
I'd suggest instead of doing another query with the same parameters just immediately running a SELECT FOUND_ROWS()
Just get the file extention then assign the file a new name with uniqid and pass the new name to the move_upload_file method. For example:
if(isset($_POST['submit'])){
$total = count($_FILES['files']['tmp_name']);
for($i=0;$i<$total;$i++){
$fileName = $_FILES['files']['name'][$i];
$ext = pathinfo($fileName, PATHINFO_EXTENSION);
$newFileName = uniqid();
$fileDest = 'filesUploaded/'.$newFileName.'.'.$ext;
if($ext === 'pdf' || 'jpeg' || 'JPG'){
move_uploaded_file($_FILES['files']['tmp_name'][$i], $fileDest);
$fileUpload = $newFileName.'.'.$ext[$i].',<br>';
}else{
echo 'Pdfs and jpegs only please';
}
}
}
A related (short-term) solution is to store your environment variables in a single file, with a predictable format, that can be sourced when starting a terminal and/or read into the notebook. For example, I have a file, .env
, that has my environment variable definitions in the format VARIABLE_NAME=VARIABLE_VALUE
(no blank lines or extra spaces). You can source this file in the .bashrc
or .bash_profile
files when beginning a new terminal session and you can read this into a notebook with something like,
import os
env_vars = !cat ../script/.env
for var in env_vars:
key, value = var.split('=')
os.environ[key] = value
I used a relative path to show that this .env
file can live anywhere and be referenced relative to the directory containing the notebook file. This also has the advantage of not displaying the variable values within your code anywhere.
I have users who have not been completing all required data.
<cfset unloadCheck=0>//a ColdFusion precheck in my page generation to see if unload check is needed
var erMsg="";
$(document).ready(function(){
<cfif q.myData eq "">
<cfset unloadCheck=1>
$("#myInput").change(function(){
verify(); //function elsewhere that checks all fields and populates erMsg with error messages for any fail(s)
if(erMsg=="") window.onbeforeunload = null; //all OK so let them pass
else window.onbeforeunload = confirmExit(); //borrowed from Jantimon above;
});
});
<cfif unloadCheck><!--- if any are outstanding, set the error message and the unload alert --->
verify();
window.onbeforeunload = confirmExit;
function confirmExit() {return "Data is incomplete for this Case:"+erMsg;}
</cfif>
If you want to delete one item
wishlist = Wishlist.objects.get(id = 20)
wishlist.delete()
If you want to delete all items in Wishlist for example
Wishlist.objects.all().delete()
Whenever you print any instance of your class, the default
toString
implementation of Object
class is called, which returns the representation that you are getting.
It contains two parts: - Type
and Hashcode
So, in student.Student@82701e that you get as output ->
student.Student
is the Type
, and82701e
is the HashCode
So, you need to override a toString
method in your Student
class to get required String representation
: -
@Override
public String toString() {
return "Student No: " + this.getStudentNo() +
", Student Name: " + this.getStudentName();
}
So, when from your main
class, you print your ArrayList
, it will invoke the toString
method for each instance, that you overrided
rather than the one in Object
class: -
List<Student> students = new ArrayList();
// You can directly print your ArrayList
System.out.println(students);
// Or, iterate through it to print each instance
for(Student student: students) {
System.out.println(student); // Will invoke overrided `toString()` method
}
In both the above cases, the toString
method overrided in Student
class will be invoked and appropriate representation of each instance will be printed.
If you have access to a linux box with mdbtools installed, you can use this Bash shell script (save as mdbconvert.sh):
#!/bin/bash
TABLES=$(mdb-tables -1 $1)
MUSER="root"
MPASS="yourpassword"
MDB="$2"
MYSQL=$(which mysql)
for t in $TABLES
do
$MYSQL -u $MUSER -p$MPASS $MDB -e "DROP TABLE IF EXISTS $t"
done
mdb-schema $1 mysql | $MYSQL -u $MUSER -p$MPASS $MDB
for t in $TABLES
do
mdb-export -D '%Y-%m-%d %H:%M:%S' -I mysql $1 $t | $MYSQL -u $MUSER -p$MPASS $MDB
done
To invoke it simply call it like this:
./mdbconvert.sh accessfile.mdb mysqldatabasename
It will import all tables and all data.
ArrayList.clear(From Java Doc):
Removes all of the elements from this list. The list will be empty after this call returns
An example with variable (ES6):
const item = document.querySelector([data-itemid="${id}"]
);
Personally, I've used this before to build a JSON to POJO converter. In the case that the JSONObject processed with the function contains an array or nested JSONObjects (implying that the data here isn't of a primitive type or String
), I attempt to invoke the setter method using class.cast()
in this fashion:
public static Object convertResponse(Class<?> clazz, JSONObject readResultObject) {
...
for(Method m : clazz.getMethods()) {
if(!m.isAnnotationPresent(convertResultIgnore.class) &&
m.getName().toLowerCase().startsWith("set")) {
...
m.invoke(returnObject, m.getParameters()[0].getClass().cast(convertResponse(m.getParameters()[0].getType(), readResultObject.getJSONObject(key))));
}
...
}
Not sure if this is extremely helpful, but as said here before, reflection is one of the very few legitimate use case of class.cast()
I can think of, at least you have another example now.
You can't. Not with 100% accuracy, anyway. The pointer has no length/size but its own. All it does is point to a particular place in memory that holds a char. If that char is part of a string, then you can use strlen
to determine what chars follow the one currently being pointed to, but that doesn't mean the array in your case is that big.
Basically:
A pointer is not an array, so it doesn't need to know what the size of the array is. A pointer can point to a single value, so a pointer can exist without there even being an array. It doesn't even care where the memory it points to is situated (Read only, heap or stack... doesn't matter). A pointer doesn't have a length other than itself. A pointer just is...
Consider this:
char beep = '\a';
void alert_user(const char *msg, char *signal); //for some reason
alert_user("Hear my super-awsome noise!", &beep); //passing pointer to single char!
void alert_user(const char *msg, char *signal)
{
printf("%s%c\n", msg, *signal);
}
A pointer can be a single char, as well as the beginning, end or middle of an array...
Think of chars as structs. You sometimes allocate a single struct on the heap. That, too, creates a pointer without an array.
Using only a pointer, to determine how big an array it is pointing to is impossible. The closest you can get to it is using calloc
and counting the number of consecutive \0 chars you can find through the pointer. Of course, that doesn't work once you've assigned/reassigned stuff to that array's keys and it also fails if the memory just outside of the array happens to hold \0
, too. So using this method is unreliable, dangerous and just generally silly. Don't. Do. It.
Another analogy:
Think of a pointer as a road sign, it points to Town X. The sign doesn't know what that town looks like, and it doesn't know or care (or can care) who lives there. It's job is to tell you where to find Town X. It can only tell you how far that town is, but not how big it is. That information is deemed irrelevant for road-signs. That's something that you can only find out by looking at the town itself, not at the road-signs that are pointing you in its direction
So, using a pointer the only thing you can do is:
char a_str[] = "hello";//{h,e,l,l,o,\0}
char *arr_ptr = &a_str[0];
printf("Get length of string -> %d\n", strlen(arr_ptr));
But this, of course, only works if the array/string is \0-terminated.
As an aside:
int length = sizeof(a)/sizeof(char);//sizeof char is guaranteed 1, so sizeof(a) is enough
is actually assigning size_t
(the return type of sizeof
) to an int
, best write:
size_t length = sizeof(a)/sizeof(*a);//best use ptr's type -> good habit
Since size_t
is an unsigned type, if sizeof
returns bigger values, the value of length
might be something you didn't expect...
While on the upper line in normal mode, hit Shift+j.
You can prepend a count too, so 3J
on the top line would join all those lines together.
For me the reason why the error appeared was that the WebForm where the error was reported has been moved from another folder, but the name of its codefile class remained unchanged and didn't correspond to the actual path.
Initial state:
Original file path: /Folder1/Subfolder1/MyWebForm.aspx.cs
Original codefile class name: Folder1_Subfolder1_MyWebForm
After the file was moved:
File path: /Folder1/MyWebForm.aspx.cs
Codefile class name (unchanged, with the error shown): Folder1_Subfolder1_MyWebForm
The solution:
Rename your codefile class Folder1_Subfolder1_MyWebForm
to one corresponding with the new path: Folder1_MyWebForm
All at once - problem solved, no errors reporting..
Although officially there is no limit specified by RFC 2616, many security protocols and recommendations state that maxQueryStrings on a server should be set to a maximum character limit of 1024. While the entire URL, including the querystring, should be set to a max of 2048 characters. This is to prevent the Slow HTTP Request DDOS vulnerability on a web server. This typically shows up as a vulnerability on the Qualys Web Application Scanner and other security scanners.
Please see the below example code for Windows IIS Servers with Web.config:
<system.webServer>
<security>
<requestFiltering>
<requestLimits maxQueryString="1024" maxUrl="2048">
<headerLimits>
<add header="Content-type" sizeLimit="100" />
</headerLimits>
</requestLimits>
</requestFiltering>
</security>
</system.webServer>
This would also work on a server level using machine.config.
Note: Limiting query string and URL length may not completely prevent Slow HTTP Requests DDOS attack but it is one step you can take to prevent it.
If you have a hash structure like this:
Parameters: {"link"=>{"title"=>"Something", "time_span"=>[{"start"=>"2017-05-06T16:00:00.000Z", "end"=>"2017-05-06T17:00:00.000Z"}]}}
Then this is how I got it to work:
params.require(:link).permit(:title, time_span: [[:start, :end]])
If the databases share server, have a login that has priveleges to both of the databases, and simply have a query run similiar to:
$query = $this->db->query("
SELECT t1.*, t2.id
FROM `database1`.`table1` AS t1, `database2`.`table2` AS t2
");
Otherwise I think you might have to run the 2 queries separately and fix the logic afterwards.
You can use the following code:
dateForButton = dateForButton.Subtract(TimeSpan.FromDays(1));
First write out 47 twice, (you like Agent 47, right?), keeping spaces as shown (each dash is a slot for a single digit. First 2 slots, then 4)
--47----47
Think you have 12
in hand (because 12 = a dozen). Multiply it by 4
, first digit of Agent 47's number, i.e. 47
, and place the result to the right of first pair you already have
12 * 4 = 48
--4748--47 <-- after placing 48 to the right of first 47
Then multiply 12
by 3
(in order to make second digit of Agent 47's number, which is 7
, you need 7 - 4 = 3
) and put the result to the right of the first 2 pairs, the last pair-slot
12 * 3 = 36
--47483647 <-- after placing 36 to the right of first two pairs
Finally drag digits one by one from your hand starting from right-most digit (2 in this case) and place them in the first empty slot you get
2-47483647 <-- after placing 2
2147483647 <-- after placing 1
There you have it! For negative limit, you can think of that as 1 more in absolute value than the positive limit.
Practise a few times, and you will get the hang of it!
its even easier:
fileList.Where(item => filterList.Contains(item))
in case you want to filter not for an exact match but for a "contains" you can use this expression:
var t = fileList.Where(file => filterList.Any(folder => file.ToUpperInvariant().Contains(folder.ToUpperInvariant())));
Try this out.

A login page isn't the only part of a database-driven website that interacts with the database.
Any user-editable input which is used to construct a database query is a potential entry point for a SQL injection attack. The attacker may not necessarily login to the site as an admin through this attack, but can do other things. They can change data, change server settings, etc. depending on the nature of the application's interaction with the database.
Appending a '
to an input is usually a pretty good test to see if it generates an error or otherwise produces unexpected behavior on the site. It's an indication that the user input is being used to build a raw query and the developer didn't expect a single quote, which changes the query structure.
Keep in mind that one page may be secure against SQL injection while another one may not. The login page, for example, may be hardened against such attacks. But a different page elsewhere in the site might be wide open. So, for example, if one wanted to login as an admin then one can use the SQL injection on that other page to change the admin password. Then return to the perfectly non-SQL-injectable login page and login as the admin.
You can use:
SELECT IDENT_CURRENT('tablename')
to access the latest identity for a perticular table.
e.g. Considering following code:
INSERT INTO dbo.MyTable(columns....) VALUES(..........)
INSERT INTO dbo.YourTable(columns....) VALUES(..........)
SELECT IDENT_CURRENT('MyTable')
SELECT IDENT_CURRENT('YourTable')
This would yield to correct value for corresponding tables.
It returns the last IDENTITY
value produced in a table, regardless of the connection that created the value, and regardless of the scope of the statement that produced the value.
IDENT_CURRENT
is not limited by scope and session; it is limited to a specified table. IDENT_CURRENT
returns the identity value generated for a specific table in any session and any scope.
This will work:
ALTER TABLE [dbo].[company] DROP CONSTRAINT [Company_CountryID_FK]

There are lots of ways to round number with precision. You should eventually use swift's standard library method rounded()
to round float number with desired precision.
To round up use .up
rule:
let f: Float = 2.2
let i = Int(f.rounded(.up)) // 3
To round down use .down
rule:
let f: Float = 2.2
let i = Int(f.rounded(.down)) // 2
To round to the nearest integer use .toNearestOrEven
rule:
let f: Float = 2.2
let i = Int(f.rounded(.toNearestOrEven)) // 2
Be aware of the following example:
let f: Float = 2.5
let i = Int(roundf(f)) // 3
let j = Int(f.rounded(.toNearestOrEven)) // 2
If you've already pushed things to a remote server (and you have other developers working off the same remote branch) the important thing to bear in mind is that you don't want to rewrite history
Don't use git reset --hard
You need to revert changes, otherwise any checkout that has the removed commits in its history will add them back to the remote repository the next time they push; and any other checkout will pull them in on the next pull thereafter.
If you have not pushed changes to a remote, you can use
git reset --hard <hash>
If you have pushed changes, but are sure nobody has pulled them you can use
git reset --hard
git push -f
If you have pushed changes, and someone has pulled them into their checkout you can still do it but the other team-member/checkout would need to collaborate:
(you) git reset --hard <hash>
(you) git push -f
(them) git fetch
(them) git reset --hard origin/branch
But generally speaking that's turning into a mess. So, reverting:
The commits to remove are the lastest
This is possibly the most common case, you've done something - you've pushed them out and then realized they shouldn't exist.
First you need to identify the commit to which you want to go back to, you can do that with:
git log
just look for the commit before your changes, and note the commit hash. you can limit the log to the most resent commits using the -n
flag: git log -n 5
Then reset your branch to the state you want your other developers to see:
git revert <hash of first borked commit>..HEAD
The final step is to create your own local branch reapplying your reverted changes:
git branch my-new-branch
git checkout my-new-branch
git revert <hash of each revert commit> .
Continue working in my-new-branch
until you're done, then merge it in to your main development branch.
The commits to remove are intermingled with other commits
If the commits you want to revert are not all together, it's probably easiest to revert them individually. Again using git log
find the commits you want to remove and then:
git revert <hash>
git revert <another hash>
..
Then, again, create your branch for continuing your work:
git branch my-new-branch
git checkout my-new-branch
git revert <hash of each revert commit> .
Then again, hack away and merge in when you're done.
You should end up with a commit history which looks like this on my-new-branch
2012-05-28 10:11 AD7six o [my-new-branch] Revert "Revert "another mistake""
2012-05-28 10:11 AD7six o Revert "Revert "committing a mistake""

Better way®
Especially that now that you're aware of the dangers of several developers working in the same branch, consider using feature branches always for your work. All that means is working in a branch until something is finished, and only then merge it to your main branch. Also consider using tools such as git-flow to automate branch creation in a consistent way.
1) Instead of PreparedStatement
use Statement
2) After executing query in ResultSet
, extract values with the help of rs.getString()
as :
Statement st=cn.createStatement();
ResultSet rs=st.executeQuery(sql);
while(rs.next())
{
rs.getString(1); //or rs.getString("column name");
}
Use mongod --shutdown

@Column
AnnotationThe nullable
attribute of the @Column
annotation has two purposes:
The HBM2DDL schema generation tool translates the @Column(nullable = false)
entity attribute to a NOT NULL
constraint for the associated table column when generating the CREATE TABLE
statement.
As I explained in the Hibernate User Guide, it's better to use a tool like Flyway instead of relying on the HBM2DDL mechanism for generating the database schema.
When flushing the Persistence Context, Hibernate ORM also uses the @Column(nullable = false)
entity attribute:
new Nullability( session ).checkNullability( values, persister, true );
If the validation fails, Hibernate will throw a PropertyValueException
, and prevents the INSERT or UPDATE statement to be executed needesly:
if ( !nullability[i] && value == null ) {
//check basic level one nullablilty
throw new PropertyValueException(
"not-null property references a null or transient value",
persister.getEntityName(),
persister.getPropertyNames()[i]
);
}
@NotNull
AnnotationThe @NotNull
annotation is defined by Bean Validation and, just like Hibernate ORM is the most popular JPA implementation, the most popular Bean Validation implementation is the Hibernate Validator framework.
When using Hibernate Validator along with Hibernate ORM, Hibernate Validator will throw a ConstraintViolation
when validating the entity.
Your Action is expecting string parameters, but you're sending a composite object.
You need to create an object that matches what you're sending.
public class Data
{
public string username { get;set; }
public string password { get;set; }
}
public JsonResult Login(Data data)
{
}
EDIT
In addition, toStringify() is probably not what you want here. Just send the object itself.
data: data,
Sorry if I've missed the point, but wouldn't the following do what you want on it's own?
SELECT distinct idCustomer FROM reservations
WHERE DATEPART(hour, insertDate) >= 2
You can do it like this:
SELECT * FROM ... WHERE name LIKE 'someone'
(It's not the solution, but in some cases is very convenient)
"The LIKE operator does a pattern matching comparison. The operand to the right contains the pattern, the left hand operand contains the string to match against the pattern. A percent symbol ("%") in the pattern matches any sequence of zero or more characters in the string. An underscore ("_") in the pattern matches any single character in the string. Any other character matches itself or its lower/upper case equivalent (i.e. case-insensitive matching). (A bug: SQLite only understands upper/lower case for ASCII characters. The LIKE operator is case sensitive for unicode characters that are beyond the ASCII range. For example, the expression 'a' LIKE 'A' is TRUE but 'æ' LIKE 'Æ' is FALSE.)."
The Java Virtual Machine (JVM) is the virtual machine that runs the Java bytecodes. The JVM doesn't understand Java source code; that's why you need compile your *.java
files to obtain *.class
files that contain the bytecodes understood by the JVM. It's also the entity that allows Java to be a "portable language" (write once, run anywhere). Indeed, there are specific implementations of the JVM for different systems (Windows, Linux, macOS, see the Wikipedia list), the aim is that with the same bytecodes they all give the same results.
To explain the difference between JDK and JRE, the best is to read the Oracle documentation and consult the diagram:
Java Runtime Environment (JRE)
The Java Runtime Environment (JRE) provides the libraries, the Java Virtual Machine, and other components to run applets and applications written in the Java programming language. In addition, two key deployment technologies are part of the JRE: Java Plug-in, which enables applets to run in popular browsers; and Java Web Start, which deploys standalone applications over a network. It is also the foundation for the technologies in the Java 2 Platform, Enterprise Edition (J2EE) for enterprise software development and deployment. The JRE does not contain tools and utilities such as compilers or debuggers for developing applets and applications.
Java Development Kit (JDK)
The JDK is a superset of the JRE, and contains everything that is in the JRE, plus tools such as the compilers and debuggers necessary for developing applets and applications.
Note that Oracle is not the only one to provide JDKs.
OpenJDK is an open-source implementation of the JDK and the base for the Oracle JDK. There is almost no difference between the Oracle JDK and the OpenJDK.
The differences are stated in this blog:
Q: What is the difference between the source code found in the OpenJDK repository, and the code you use to build the Oracle JDK?
A: It is very close - our build process for Oracle JDK releases builds on OpenJDK 7 by adding just a couple of pieces, like the deployment code, which includes Oracle's implementation of the Java Plugin and Java WebStart, as well as some closed source third party components like a graphics rasterizer, some open source third party components, like Rhino, and a few bits and pieces here and there, like additional documentation or third party fonts. Moving forward, our intent is to open source all pieces of the Oracle JDK except those that we consider commercial features such as JRockit Mission Control (not yet available in Oracle JDK), and replace encumbered third party components with open source alternatives to achieve closer parity between the code bases.
Update for JDK 11 - An article from Donald Smith try to disambiguate the difference between Oracle JDK and Oracle's OpenJDK : https://blogs.oracle.com/java-platform-group/oracle-jdk-releases-for-java-11-and-later
Just make a new folder inside C:\xampp\htdocs like C:\xampp\htdocs\test and place your index.php or whatever file in it. Access it by browsing localhost/test/
Good luck!
.each()
should work for you. http://api.jquery.com/jQuery.each/ or http://api.jquery.com/each/ or you could use .map
.
var newArray = $(array).map(function(i) {
return $('#event' + i, response).html();
});
Edit: I removed the adding of the prepended 0 since it is suggested to not use that.
If you must have it use
var newArray = $(array).map(function(i) {
var number = '' + i;
if (number.length == 1) {
number = '0' + number;
}
return $('#event' + number, response).html();
});
This one is a more generic version of the ideas mentioned above... It simply checks whether there is any value in the model, and if not, it sets the value to the model.
JS:
function defaultValueDirective() {
return {
restrict: 'A',
controller: [
'$scope', '$attrs', '$parse',
function ($scope, $attrs, $parse) {
var getter = $parse($attrs.ngModel);
var setter = getter.assign;
var value = getter();
if (value === undefined || value === null) {
var defaultValueGetter = $parse($attrs.defaultValue);
setter($scope, defaultValueGetter());
}
}
]
}
}
HTML (usage example):
<select class="form-control"
ng-options="v for (i, v) in compressionMethods"
ng-model="action.parameters.Method"
default-value="'LZMA2'"></select>
You have 2 choices:
1) Either specify the column name list (without the identity column).
2) SET IDENTITY_INSERT tablename ON, followed by insert statements that provide explicit values for the identity column, followed by SET IDENTITY_INSERT tablename OFF.
If you are avoiding a column name list, perhaps this 'trick' might help?:
-- Get a comma separated list of a table's column names
SELECT STUFF(
(SELECT
',' + COLUMN_NAME AS [text()]
FROM
INFORMATION_SCHEMA.COLUMNS
WHERE
TABLE_NAME = 'TableName'
Order By Ordinal_position
FOR XML PATH('')
), 1,1, '')
You need to look at the size of the mantissa. An IEEE 754 64 bit floating point number (which has 52 bits, plus 1 implied) can exactly represent integers with an absolute value of less than or equal to 2^53.
Have a reference of stream form successHandle
var streamRef;
var handleVideo = function (stream) {
streamRef = stream;
}
//this will stop video and audio both track
streamRef.getTracks().map(function (val) {
val.stop();
});
use property UseSimpleDictionaryFormat
on DataContractJsonSerializer
and set it to true
.
Does the job :)
In JQuery you can call
$("form:first").trigger("submit")
Don't know if that is much better. I think form.submit(); is pretty universal.
For angular 5+
version. Putting version helps as angular makes lot of changes.
ngOnInit() {
this.myForm = formBuilder.group({
firstName: 'Thomas',
lastName: 'Mann'
})
this.formControlValueChanged() // Note if you are doing an edit/fetching data from an observer this must be called only after your form is properly initialized otherwise you will get error.
}
formControlValueChanged(): void {
this.myForm.valueChanges.subscribe(value => {
console.log('value changed', value)
})
}
The only way I succeed to not having an error because of NULL, or special characters or empty string is by doing this:
SELECT REGEXP_REPLACE(COALESCE(<column>::character varying, '0'), '[^0-9]*' ,'0')::integer FROM table
By default, git will update execute file permissions if you change them. It will not change or track any other permissions.
If you don't see any changes when modifying execute permission, you probably have a configuration in git which ignore file mode.
Look into your project, in the .git
folder for the config
file and you should see something like this:
[core]
filemode = false
You can either change it to true
in your favorite text editor, or run:
git config core.filemode true
Then, you should be able to commit normally your files. It will only commit the permission changes.
import six
if six.PY2:
input = raw_input
print(input("What's your name? "))
According to the documentation. You can use:
$locationProvider.html5Mode(true).hashPrefix('!');
NB: If your browser does not support to HTML 5. Dont worry :D it have fallback to hashbang mode. So, you don't need to check with
if(window.history && window.history.pushState){ ... }
manually
For example: If you click: <a href="/other">Some URL</a>
In HTML5 Browser:
angular will automatically redirect to example.com/other
In Not HTML5 Browser:
angular will automatically redirect to example.com/#!/other
In comments under another answer, you indicated you are using a dodgy version of g++
under MS Windows.
In this case, -std=c++11
as suggested by the top answer would still not fix the problem.
Please see the following thread which does discuss your situation: std::stoi doesn't exist in g++ 4.6.1 on MinGW
Try to provide complex pathnames in double-quotes (and include file extensions at the end for files.)
For files:
call "C:\example file.exe"
For Directory:
cd "C:\Users\User Name\New Folder"
CMD interprets text with double quotes ("xyz") as one string and text within single quotes ('xyz') as a command. For example:
FOR %%A in ('dir /b /s *.txt') do ('command')
FOR %%A in ('dir /b /s *.txt') do (echo "%%A")
And one good thing, cmd is not* case sensitive like bash. So "New fiLE.txt" and "new file.TXT" is alike to it.
*Note: The %%A variables in above case is case-sensitive (%%A not equal to %%a).
Here's an example with Alarm Manager using Kotlin:
class MainActivity : AppCompatActivity() {
val editText: EditText by bindView(R.id.edit_text)
val timePicker: TimePicker by bindView(R.id.time_picker)
val buttonSet: Button by bindView(R.id.button_set)
val buttonCancel: Button by bindView(R.id.button_cancel)
val relativeLayout: RelativeLayout by bindView(R.id.activity_main)
var notificationId = 0
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
timePicker.setIs24HourView(true)
val alarmManager = getSystemService(Context.ALARM_SERVICE) as AlarmManager
buttonSet.setOnClickListener {
if (editText.text.isBlank()) {
Toast.makeText(applicationContext, "Title is Required!!", Toast.LENGTH_SHORT).show()
return@setOnClickListener
}
alarmManager.set(
AlarmManager.RTC_WAKEUP,
Calendar.getInstance().apply {
set(Calendar.HOUR_OF_DAY, timePicker.hour)
set(Calendar.MINUTE, timePicker.minute)
set(Calendar.SECOND, 0)
}.timeInMillis,
PendingIntent.getBroadcast(
applicationContext,
0,
Intent(applicationContext, AlarmBroadcastReceiver::class.java).apply {
putExtra("notificationId", ++notificationId)
putExtra("reminder", editText.text)

override fun onResume() {
super.onResume()

private fun reset() {

minute = now.get(Calendar.MINUTE)
}
editText.setText("")
}
}
As I understand it, you want the server be able to send messages through from client 1 to client 2. You cannot directly connect two clients because one of the two ends of a WebSocket connection needs to be a server.
This is some pseudocodish JavaScript:
Client:
var websocket = new WebSocket("server address");
websocket.onmessage = function(str) {
console.log("Someone sent: ", str);
};
// Tell the server this is client 1 (swap for client 2 of course)
websocket.send(JSON.stringify({
id: "client1"
}));
// Tell the server we want to send something to the other client
websocket.send(JSON.stringify({
to: "client2",
data: "foo"
}));
Server:
var clients = {};
server.on("data", function(client, str) {
var obj = JSON.parse(str);
if("id" in obj) {
// New client, add it to the id/client object
clients[obj.id] = client;
} else {
// Send data to the client requested
clients[obj.to].send(obj.data);
}
});
Cast table to Enumerable
, then you call LINQ methods with using ToString()
method inside:
var example = contex.table_name.AsEnumerable()
.Select(x => new {Date = x.date.ToString("M/d/yyyy")...)
But be careful, when you calling AsEnumerable
or ToList
methods because you will request all data from all entity before this method. In my case above I read all table_name
rows by one request.
I'm quite late to the party but the following hack will outperform both correlated subqueries and any analytics function but has one restriction: values must convert to strings. So it works for dates, numbers and other strings. The code does not look good but the execution profile is great.
select
userid,
to_number(substr(max(to_char(date,'yyyymmdd') || to_char(value)), 9)) as value,
max(date) as date
from
users
group by
userid
The reason why this code works so well is that it only needs to scan the table once. It does not require any indexes and most importantly it does not need to sort the table, which most analytics functions do. Indexes will help though if you need to filter the result for a single userid.
You could also have a JSON file with NODE_ENV as the top level. IMO, this is a better way to express configuration settings (as opposed to using a script that returns settings).
var config = require('./env.json')[process.env.NODE_ENV || 'development'];
Example for env.json:
{
"development": {
"MONGO_URI": "mongodb://localhost/test",
"MONGO_OPTIONS": { "db": { "safe": true } }
},
"production": {
"MONGO_URI": "mongodb://localhost/production",
"MONGO_OPTIONS": { "db": { "safe": true } }
}
}
res = ActiveRecord::Base.connection_pool.with_connection { |con| con.exec_query( "SELECT 1;" ) }
The above code is an example for
Steps:
This gives you three files:
PushChatKey.p12
)aps_development.cer
Go to the folder where you downloaded the files, in my case the Desktop:
$ cd ~/Desktop/
Convert the .cer file into a .pem file:
$ openssl x509 -in aps_development.cer -inform der -out PushChatCert.pem
Convert the private key’s .p12 file into a .pem file:
$ openssl pkcs12 -nocerts -out PushChatKey.pem -in PushChatKey.p12
Enter Import Password:
MAC verified OK
Enter PEM pass phrase:
Verifying - Enter PEM pass phrase:
You first need to enter the passphrase for the .p12 file so that openssl can read it. Then you need to enter a new passphrase that will be used to encrypt the PEM file. Again for this tutorial I used “pushchat” as the PEM passphrase. You should choose something more secure. Note: if you don’t enter a PEM passphrase, openssl will not give an error message but the generated .pem file will not have the private key in it.
Finally, combine the certificate and key into a single .pem file:
$ cat PushChatCert.pem PushChatKey.pem > ck.pem
I 'm using this :
function getFirstWord(str) {
let spaceIndex = str.indexOf(' ');
return spaceIndex === -1 ? str : str.substr(0, spaceIndex);
};
The STL does not have such a method available already.
However, you can either use C's strtok()
function by using the std::string::c_str()
member, or you can write your own. Here is a code sample I found after a quick Google search ("STL string split"):
void Tokenize(const string& str,
vector<string>& tokens,
const string& delimiters = " ")
{
// Skip delimiters at beginning.
string::size_type lastPos = str.find_first_not_of(delimiters, 0);
// Find first "non-delimiter".
string::size_type pos = str.find_first_of(delimiters, lastPos);
while (string::npos != pos || string::npos != lastPos)
{
// Found a token, add it to the vector.
tokens.push_back(str.substr(lastPos, pos - lastPos));
// Skip delimiters. Note the "not_of"
lastPos = str.find_first_not_of(delimiters, pos);
// Find next "non-delimiter"
pos = str.find_first_of(delimiters, lastPos);
}
}

If you have questions about the code sample, leave a comment and I will explain.
And just because it does not implement a typedef
called iterator or overload the <<
operator does not mean it is bad code. I use C functions quite frequently. For example, printf
and scanf
both are faster than std::cin
and std::cout
(significantly), the fopen
syntax is a lot more friendly for binary types, and they also tend to produce smaller EXEs.
Don't get sold on this "Elegance over performance" deal.
Was looking for the solution of a similar problem. Thanks to the answer provided by Davlet and Cupcake I was able to solve my problem.
Posting this answer here since I think this is the intended question
So I guess generally the problem that people like me face is what to do when a repo is cloned by another user on a server and that user is no longer associated with the repo.
How to pull from the repo without using the credentials of the old user ?
You edit the .git/config file of your repo.
and change
url = https://<old-username>@github.com/abc/repo.git/
to
url = https://<new-username>@github.com/abc/repo.git/
After saving the changes, from now onwards git pull will pull data while using credentials of the new user.
I hope this helps anyone with a similar problem
Do a describe on dba_arguments, dba_errors, dba_procedures, dba_objects, dba_source, dba_object_size. Each of these has part of the pictures for looking at the procedures and functions.
Also the object_type in dba_objects for packages is 'PACKAGE' for the definition and 'PACKAGE BODY" for the body.
If you are comparing schemas on the same database then try:
select * from dba_objects
where schema_name = 'ASCHEMA'
and object_type in ( 'PROCEDURE', 'PACKAGE', 'FUNCTION', 'PACKAGE BODY' )
minus
select * from dba_objects
where schema_name = 'BSCHEMA'
and object_type in ( 'PROCEDURE', 'PACKAGE', 'FUNCTION', 'PACKAGE BODY' )
and switch around the orders of ASCHEMA and BSCHEMA.
If you also need to look at triggers and comparing other stuff between the schemas you should take a look at the Article on Ask Tom about comparing schemas

I've found that you can move div elements to the next line simply by setting the property
Display: block;
On each div.
To view vector std::vector myVector contents, just type in GDB:
(gdb) print myVector
This will produce an output similar to:
$1 = std::vector of length 3, capacity 4 = {10, 20, 30}
To achieve above, you need to have gdb 7 (I tested it on gdb 7.01) and some python pretty-printer. Installation process of these is described on gdb wiki.
What is more, after installing above, this works well with Eclipse C++ debugger GUI (and any other IDE using GDB, as I think).
While astype
is probably the "best" option there are several other ways to convert it to an integer array. I'm using this arr
in the following examples:
>>> import numpy as np
>>> arr = np.array([1,2,3,4], dtype=float)
>>> arr
array([ 1., 2., 3., 4.])
int*
functions from NumPy>>> np.int64(arr)
array([1, 2, 3, 4])
>>> np.int_(arr)
array([1, 2, 3, 4])
*array
functions themselves:>>> np.array(arr, dtype=int)
array([1, 2, 3, 4])
>>> np.asarray(arr, dtype=int)
array([1, 2, 3, 4])
>>> np.asanyarray(arr, dtype=int)
array([1, 2, 3, 4])
astype
method (that was already mentioned but for completeness sake):>>> arr.astype(int)
array([1, 2, 3, 4])
Note that passing int
as dtype to astype
or array
will default to a default integer type that depends on your platform. For example on Windows it will be int32
, on 64bit Linux with 64bit Python it's int64
. If you need a specific integer type and want to avoid the platform "ambiguity" you should use the corresponding NumPy types like np.int32
or np.int64
.

Also I see a lot of good and explanatory answers here, so I want to give my point of view here, including some extra information what I noticed when using this method.
Unit testing
For the last two years, I have written a hobby project and I did not write unit tests for it. After writing about 50K lines I found out it would be really necessary to write unit tests. I did not use interfaces (or very sparingly) ... and when I made my first unit test, I found out it was complicated. Why?
Because I had to make a lot of class instances, used for input as class variables and/or parameters. So the tests look more like integration tests (having to make a complete 'framework' of classes since all was tied together).
Fear of interfaces So I decided to use interfaces. My fear was that I had to implement all functionality everywhere (in all used classes) multiple times. In some way this is true, however, by using inheritance it can be reduced a lot.
Combination of interfaces and inheritance I found out the combination is very good to be used. I give a very simple example.
public interface IPricable
{
int Price { get; }
}
public interface ICar : IPricable
public abstract class Article
{
public int Price { get { return ... } }
}
public class Car : Article, ICar
{
// Price does not need to be defined here
}
This way copying code is not necessary, while still having the benefit of using a car as interface (ICar).
Why do you need to state both 'x' and 'y' before the ':'?
Because a lambda is (conceptually) the same as a function, just written inline. Your example is equivalent to
def f(x, y) : return x + y
just without binding it to a name like f
.
Also how do you make it return multiple arguments?
The same way like with a function. Preferably, you return a tuple:
lambda x, y: (x+y, x-y)
Or a list, or a class, or whatever.
The thing with self.entry_1.bind
should be answered by Demosthenex.
For ex .. add class:
btn-lg - LARGE
btn-sm - SMALL
btn-xs - Very small
<button type=button class="btn btn-default btn-lg">
<span class="glyphicon glyphicon-star" aria-hidden=true></span> Star
</button>
<button type=button class="btn btn-default">
<span class="glyphicon glyphicon-star" aria-hidden=true></span>Star
</button>
<button type=button class="btn btn-default btn-sm">
<span class="glyphicon glyphicon-star" aria-hidden=true></span> Star
</button>
<button type=button class="btn btn-default btn-xs">
<span class="glyphicon glyphicon-star" aria-hidden=true></span> Star
</button>

This takes smhg from here and curt's from Last index of a given substring in MySQL and combines them. This is for mysql, all I needed was to get a decent split of name to first_name last_name with the last name a single word, the first name everything before that single word, where the name could be null, 1 word, 2 words, or more than 2 words. Ie: Null; Mary; Mary Smith; Mary A. Smith; Mary Sue Ellen Smith;
So if name is one word or null, last_name is null. If name is > 1 word, last_name is last word, and first_name all words before last word.
Note that I've already trimmed off stuff like Joe Smith Jr. ; Joe Smith Esq. and so on, manually, which was painful, of course, but it was small enough to do that, so you want to make sure to really look at the data in the name field before deciding which method to use.
Note that this also trims the outcome, so you don't end up with spaces in front of or after the names.
I'm just posting this for others who might google their way here looking for what I needed. This works, of course, test it with the select first.
It's a one time thing, so I don't care about efficiency.

Instead of adding any tag which is never a good solution. You can always use margin
property with the required element.
You can add the margin on row class itself. So it will affect globally.
.row{
margin-top: 30px;
margin-bottom: 30px
}
Update: Better solution in all cases would be to introduce a new class and then use it along with .row
class.
.row-m-t{
margin-top : 20px
}
Then use it wherever you want
<div class="row row-m-t"></div>
Great answer above. Another way is to use the great yaml jq wrapper tool, yq at https://github.com/kislyuk/yq
Save your JSON example to a file, say ex.json and then
yq -y '.' ex.json

You can add property to your model as follows:
public string DetailsClass { get { return Details.Count > 0 ? "show" : "hide" } }
and then your view will be simpler and will contain no logic at all:
<div class="details @Model.DetailsClass"/>
This will work even with many classes and will not render class if it is null:
<div class="@Model.Class1 @Model.Class2"/>
with 2 not null properties will render:
<div class="class1 class2"/>
if class1 is null
<div class=" class2"/>
In this context, the word "stub" is used in place of "mock", but for the sake of clarity and precision, the author should have used "mock", because "mock" is a sort of stub, but for testing. To avoid further confusion, we need to define what a stub is.
In the general context, a stub is a piece of program (typically a function or an object) that encapsulates the complexity of invoking another program (usually located on another machine, VM, or process - but not always, it can also be a local object). Because the actual program to invoke is usually not located on the same memory space, invoking it requires many operations such as addressing, performing the actual remote invocation, marshalling/serializing the data/arguments to be passed (and same with the potential result), maybe even dealing with authentication/security, and so on. Note that in some contexts, stubs are also called proxies (such as dynamic proxies in Java).
A mock is a very specific and restrictive kind of stub, because a mock is a replacement of another function or object for testing. In practice we often use mocks as local programs (functions or objects) to replace a remote program in the test environment. In any case, the mock may simulate the actual behaviour of the replaced program in a restricted context.
Most famous kinds of stubs are obviously for distributed programming, when needing to invoke remote procedures (RPC) or remote objects (RMI, CORBA). Most distributed programming frameworks/libraries automate the generation of stubs so that you don't have to write them manually. Stubs can be generated from an interface definition, written with IDL for instance (but you can also use any language to define interfaces).
Typically, in RPC, RMI, CORBA, and so on, one distinguishes client-side stubs, which mostly take care of marshaling/serializing the arguments and performing the remote invocation, and server-side stubs, which mostly take care of unmarshaling/deserializing the arguments and actually execute the remote function/method. Obviously, client stubs are located on the client side, while sever stubs (often called skeletons) are located on the server side.
Writing good efficient and generic stubs becomes quite challenging when dealing with object references. Most distributed object frameworks such as RMI and CORBA deal with distributed objects references, but that's something most programmers avoid in REST environments for instance. Typically, in REST environments, JavaScript programmers make simple stub functions to encapsulate the AJAX invocations (object serialization being supported by JSON.parse
and JSON.stringify
). The Swagger Codegen project provides an extensive support for automatically generating REST stubs in various languages.
For cases when we need to check from our own service/background-thread whether our app is in foreground or not. This is how I implemented it, and it works fine for me:
public class TestApplication extends Application implements Application.ActivityLifecycleCallbacks {
public static WeakReference<Activity> foregroundActivityRef = null;
@Override
public void onActivityStarted(Activity activity) {
foregroundActivityRef = new WeakReference<>(activity);
}
@Override
public void onActivityStopped(Activity activity) {
if (foregroundActivityRef != null && foregroundActivityRef.get() == activity) {
foregroundActivityRef = null;
}
}
// IMPLEMENT OTHER CALLBACK METHODS
}
Now to check from other classes, whether app is in foreground or not, simply call:
if(TestApplication.foregroundActivityRef!=null){
// APP IS IN FOREGROUND!
// We can also get the activity that is currently visible!
}
Update (as pointed out by SHS):
Do not forget to register for the callbacks in your Application class's onCreate
method.
@Override
public void onCreate() {
...
registerActivityLifecycleCallbacks(this);
}
For specific month and year use date() as natural language as following
$first_date = date('d-m-Y',strtotime('first day of april 2010'));
$last_date = date('d-m-Y',strtotime('last day of april 2010'));
// Isn't it simple way?
but for Current month
$first_date = date('d-m-Y',strtotime('first day of this month'));
$last_date = date('d-m-Y',strtotime('last day of this month'));
I have your answer, as I just had the same problem today:
Someone made a working vba code that changes the vba protection password to "macro", for all excel files, including .xlsm (2007+ versions). You can see how it works by browsing his code.
This is the guy's blog: http://lbeliarl.blogspot.com/2014/03/excel-removing-password-from-vba.html Here's the file that does the work: https://docs.google.com/file/d/0B6sFi5sSqEKbLUIwUTVhY3lWZE0/edit
Pasted from a previous post from his blog:
For Excel 2007/2010 (.xlsm) files do following steps:
Find and copy the value from parameter DPB (value in quotation mark), example: DPB="282A84CBA1CBA1345FCCB154E20721DE77F7D2378D0EAC90427A22021A46E9CE6F17188A". (This value generated for 'macro' password. You can use this DPB value to skip steps 1-8)
Do steps 4-7 for file with unknown password (file you want to unlock).
Change DBP value in this file on value that you have copied in step 8.
If copied value is shorter than in encrypted file you should populate missing characters with 0 (zero). If value is longer - that is not a problem (paste it as is).
Save the 'vbaProject.bin' file and exit from hex editor.
It could also be possible that you have created the "Products" in your login schema and you were trying to execute the same in a different schema (probably dbo)
Steps to resolve this issue
1)open the management studio 2) Locate the object in the explorer and identify the schema under which your object is? ( it is the text before your object name ). In the image below its the "dbo" and my object name is action status
if you see it like "yourcompanydoamin\yourloginid" then you should you can modify the permission on that specific schema and not any other schema.

KEEPING THE DIRECTORY NAME
The subdirectory-filter (or the shorter command git subtree) works good but did not work for me since they remove the directory name from the commit info. In my scenario I just want to merge parts of one repository into another and retain the history WITH full path name.
My solution was to use the tree-filter and to simply remove the unwanted files and directories from a temporary clone of the source repository, then pull from that clone into my target repository in 5 simple steps.
# 1. clone the source
git clone ssh://<user>@<source-repo url>
cd <source-repo>
# 2. remove the stuff we want to exclude
git filter-branch --tree-filter "rm -rf <files to exclude>" --prune-empty HEAD
# 3. move to target repo and create a merge branch (for safety)
cd <path to target-repo>
git checkout -b <merge branch>
# 4. Add the source-repo as remote
git remote add source-repo <path to source-repo>
# 5. fetch it
git pull source-repo master
# 6. check that you got it right (better safe than sorry, right?)

Google Closure Compiler generally achieves smaller files than YUI Compressor, particularly if you use the advanced mode, which looks worryingly meddlesome to me but has worked well on the one project I've used it on:
Several big projects use UglifyJS, and I've been very impressed with it since switching.
To add the answer provided by @Cody Brocious
In the context of virtualization where you are emulating a new system(CPU , I/O etc ) to a virtual machine we can see the following categories of emulators.
Interpretation: bochs is an example of interpreter , it is a x86 PC emulator,it takes each instruction from guest system translates it in another set of instruction( of the host ISA) to produce the intended effect.Yes it is very slow , it doesn't cache anything so every instruction goes through the same cycle.
Dynamic emalator: Qemu is a dynamic emulator. It does on the fly translation of guest instruction also caches results.The best part is that executes as many instructions as possible directly on the host system so that emulation is faster. Also as mentioned by Cody, it divides the code into blocks ( 1 single flow of execution).
Static emulator: As far I know there are no static emulator that can be helpful in virtualization.

For configuring routes, you have to configure API Gateway to accept routes. otherwise other than the base route everything else will end up in a {missing auth token} or something other...
Once you configured API Gateway to accept routes, make sure that you enabled lambda proxy, so that things will work better,
to access routes,
new_route = event['path'] # /{some_url}
to access query parameter
query_param = event['queryStringParameters'][{query_key}]
if you want to reload your entire page, like it seems, just inject $window into your controller and then call
$window.location.href = '/';
but if you only want to reload your current view, inject $scope, $state and $stateParams (the latter just in case you need to have some parameters change in this upcoming reload, something like your page number), then call this within any controller method:
$stateParams.page = 1;
$state.reload();
AngularJS v1.3.15 angular-ui-router v0.2.15
I've done it like this:
var input = document.querySelector('input[type="file"]')
var data = new FormData()
data.append('file', input.files[0])
data.append('user', 'hubot')
fetch('/avatars', {
method: 'POST',
body: data
})
Effects are always executed after the render phase is completed even if you setState inside the one effect, another effect will read the updated state and take action on it only after the render phase.
Having said that its probably better to take both actions in the same effect unless there is a possibility that b
can change due to reasons other than changing a
in which case too you would want to execute the same logic
ServerRoot "xampp\apache"
ServerRoot "D:\Hacking Tools 2\Programs\XAMPP V2\apache"
ServerRoot "D:\XAMPP\apache"
It worked for me, if it doesn't work for you, just comment with the error value after opening the xampp_start.exe
Just cast each character to an int:
for (int i = 0; i < str.length; i++)
Console.Write(((int)str[i]).ToString());
Here seems to be an even better answer with 'in' clause that allows for multiple keys for the join:
update fp_active set STATE='E',
LAST_DATE_MAJ = sysdate where (client,code) in (select (client,code) from fp_detail
where valid = 1) ...
The full example is here: http://forums.devshed.com/oracle-development-96/how-to-update-from-two-tables-195893.html - from web archive since link was dead.
The beef is in having the columns that you want to use as the key in parentheses in the where clause before 'in' and have the select statement with the same column names in parentheses. where (column1,column2) in ( select (column1,column2) from table where "the set I want" );
SET GLOBAL auto_increment_offset=1;
SET GLOBAL auto_increment_increment=5;
auto_increment_offset: interval between successive column values
auto_increment_offset: determines the starting point for the AUTO_INCREMENT column value. The default value is 1.
Lambda expressions are inline functions! I think, that C# doesn`t have a extra attribute like inline or something like that!
I find the easy way to do it for non-repeatable updates is to use MS Access and create a linked table, then update the data as you need. I guess the MS Access team doesn't talk to the SMSS team :)
The problem is related to permission. Copy following code into onCreate() method. The issue will get solved.
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
if (checkSelfPermission(Manifest.permission.CAMERA) != PackageManager.PERMISSION_GRANTED) {
requestPermissions(new String[] {Manifest.permission.CAMERA}, 1);
}
}
After that wait for the user action and handle his decision.
@Override
public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) {
switch (requestCode) {
case CAMERA_PERMISSION_REQUEST_CODE:
// If request is cancelled, the result arrays are empty.
if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
//Start your camera handling here
} else {
AppUtils.showUserMessage("You declined to allow the app to access your camera", this);
}
}
}
I had the same problem even after installing JDK 1.7. I corrected it by adding the bin directory to my PATH. So I went to
computer>properties>advanced>environment variables
and then added
C:\Program Files\Java\jdk1.7.0_55\bin;
then I followed these instructions
http://clean-clouds.com/2012/12/06/how-to-install-and-add-jre7-in-eclipse/
CTRL + SCR LK (Scroll Lock) worked for me.
In the constructor of
public class ErrorEventArg : EventArgs
You have to add "base" as follows:
public ErrorEventArg(string errorMsg, string lastQuery) : base (string errorMsg, string lastQuery)
{
ErrorMsg = errorMsg;
LastQuery = lastQuery;
}
That solved it for me
When Object variables are initially used in a language like Java, they have absolutely no value at all - not zero, but literally no value - that is null
For instance: String s;
If you were to use s
, it would actually have a value of null
, because it holds absolute nothing.
An empty string, however, is a value - it is a string of no characters.
String s; //Inits to null
String a =""; //A blank string
Null
is essentially 'nothing' - it's the default 'value' (to use the term loosely) that Java assigns to any Object variable that was not initialized.
Null
isn't really a value - and as such, doesn't have properties. So, calling anything that is meant to return a value - such as .length()
, will invariably return an error, because 'nothing' cannot have properties.
To go into more depth, by creating s1 = "";
you are initializing an object, which can have properties, and takes up relevant space in memory. By using s2;
you are designating that variable name to be a String, but are not actually assigning any value at that point.
Internal classes need to be tested and there is an assemby attribute:
using System.Runtime.CompilerServices;
[assembly:InternalsVisibleTo("MyTests")]
Add this to the project info file, e.g. Properties\AssemblyInfo.cs
.
Use position:fixed
, as previously stated, IE6 doesn't recognize position:fixed
, but with some css magic you can get IE6 to behave:
html, body {
height: 100%;
overflow:auto;
}
body #fixedElement {
position:fixed !important;
position: absolute; /*ie6 */
bottom: 0;
}
The !important
flag makes it so you don't have to use a conditional comment for IE. This will have #fixedElement
use position:fixed
in all browsers but IE, and in IE
, position:absolute
will take effect with bottom:0
. This will simulate position:fixed
for IE6

I think Alt+R+F is the correct one for creating property from a variable declaration
Modulo is the remainder, not division.
2 / 4 = 0R2
2 % 4 = 2
The sign %
is often used for the modulo operator, in lieu of the word mod
.
For x % 4
, you get the following table (for 1-10)
x x%4
------
1 1
2 2
3 3
4 0
5 1
6 2
7 3
8 0
9 1
10 2
Object does not have forEach
, it belongs to Array
prototype. If you want to iterate through each key-value pair in the object and take the values. You can do this:
Object.keys(a).forEach(function (key){
console.log(a[key]);
});
Usage note: For an object v = {"cat":"large", "dog": "small", "bird": "tiny"};
, Object.keys(v)
gives you an array of the keys so you get ["cat","dog","bird"]
You can use $("#drpList").val();
According to my humble opinion and my work experience with git, staging area is not the same as index. I may be wrong of course, but as I said, my experience in using git and my logic tell me, that index is a structure that follows your changes to your working area(local repository) that are not excluded by ignoring settings and staging area is to keep files that are already confirmed to be committed, aka files in index on which add command was run on. You don't notice and realize that "slight" difference, because you use
git commit -a -m "comment"
adding indexed and cached files to stage area and committing in one command or using IDEs like IDEA for that too often. And cache is that what keeps changes in indexed files.
If you want to remove file from index that has not been added to staging area before, options proposed before match for you, but...
If you have done that already, you will need to use
Git restore --staged <file>
And, please, don't ask me where I was 10 years ago... I missed you, this answer is for further generations)
Thunks versus Sagas
Redux-Thunk
and Redux-Saga
differ in a few important ways, both are middleware libraries for Redux (Redux middleware is code that intercepts actions coming into the store via the dispatch() method).
An action can be literally anything, but if you're following best practices, an action is a plain javascript object with a type field, and optional payload, meta, and error fields. e.g.
const loginRequest = {
type: 'LOGIN_REQUEST',
payload: {
name: 'admin',
password: '123',
}, };
Redux-Thunk
In addition to dispatching standard actions, Redux-Thunk
middleware allows you to dispatch special functions, called thunks
.
Thunks (in Redux) generally have the following structure:
export const thunkName =
parameters =>
(dispatch, getState) => {
// Your application logic goes here
};
That is, a thunk
is a function that (optionally) takes some parameters and returns another function. The inner function takes a dispatch function
and a getState
function -- both of which will be supplied by the Redux-Thunk
middleware.
Redux-Saga
Redux-Saga
middleware allows you to express complex application logic as pure functions called sagas. Pure functions are desirable from a testing standpoint because they are predictable and repeatable, which makes them relatively easy to test.
Sagas are implemented through special functions called generator functions. These are a new feature of ES6 JavaScript
. Basically, execution jumps in and out of a generator everywhere you see a yield statement. Think of a yield
statement as causing the generator to pause and return the yielded value. Later on, the caller can resume the generator at the statement following the yield
.
A generator function is one defined like this. Notice the asterisk after the function keyword.
function* mySaga() {
// ...
}
Once the login saga is registered with Redux-Saga
. But then the yield
take on the the first line will pause the saga until an action with type 'LOGIN_REQUEST'
is dispatched to the store. Once that happens, execution will continue.
When you define you own html form then you have to include authentication token string ,that should be sent to controller for security reasons. If you use rails form helper to generate the authenticity token is added to form as follow.
<form accept-charset="UTF-8" action="/login/signin" method="post">
<div style="display:none">
<input name="utf8" type="hidden" value="✓" />
<input name="authenticity_token" type="hidden" value="x37DrAAwyIIb7s+w2+AdoCR8cAJIpQhIetKRrPgG5VA=">
</div>
...
</form>
So the solution to the problem is either to add authenticity_token field or use rails form helpers rather then compromising security etc.
You first need to understand Call Stack. Understanding Call stack will also give you clarity to how "function hierarchy and execution order" works in JavaScript Engine.
The call stack is primarily used for function invocation (call). Since there is only one call stack. Hence, all function(s) execution get pushed and popped one at a time, from top to bottom.
It means the call stack is synchronous. When you enter a function, an entry for that function is pushed onto the Call stack and when you exit from the function, that same entry is popped from the Call Stack. So, basically if everything is running smooth, then at the very beginning and at the end, Call Stack will be found empty.
Here is the illustration of Call Stack:
Now, if you provide too many arguments or caught inside any unhandled recursive call. You will encounter
RangeError: Maximum call stack size exceeded
which is quite obvious as explained by others.
Hope this helps !
look at it is informative [Qualified identifiers
A qualified id-expression is an unqualified id-expression prepended by a scope resolution operator ::, and optionally, a sequence of enumeration, (since C++11)class or namespace names or decltype expressions (since C++11) separated by scope resolution operators. For example, the expression std::string::npos is an expression that names the static member npos in the class string in namespace std. The expression ::tolower names the function tolower in the global namespace. The expression ::std::cout names the global variable cout in namespace std, which is a top-level namespace. The expression boost::signals2::connection names the type connection declared in namespace signals2, which is declared in namespace boost.
The keyword template may appear in qualified identifiers as necessary to disambiguate dependent template names]1

Create a model which contains your list and other things you need for the view.
For example:
public class MyModel
{
public List<string> _MyList { get; set; }
}
From the action method put your desired list to the Model, _MyList
property, like:
public ActionResult ArticleList(MyModel model)
{
model._MyList = new List<string>{"item1","item2","item3"};
return PartialView(@"~/Views/Home/MyView.cshtml", model);
}
In your view access the model as follows
@model MyModel
foreach (var item in Model)
{
<div>@item</div>
}
I think it will help for start.
Know the master key yourself. Don't hard code it.
Use py-bcrypt
(bcrypt), powerful hashing technique to generate a password yourself.
Basically you can do this (an idea...)
import bcrypt
from getpass import getpass
master_secret_key = getpass('tell me the master secret key you are going to use')
salt = bcrypt.gensalt()
combo_password = raw_password + salt + master_secret_key
hashed_password = bcrypt.hashpw(combo_password, salt)
save salt and hashed password somewhere so whenever you need to use the password, you are reading the encrypted password, and test against the raw password you are entering again.
This is basically how login should work these days.
from pip._internal import main
Edit the pip code from
sudo nano /usr/bin/pip3
You can also set LD_RUN_PATH to /usr/local/lib in your user environment when you compile pycurl in the first place. This will embed /usr/local/lib in the RPATH attribute of the C extension module .so so that it automatically knows where to find the library at run time without having to have LD_LIBRARY_PATH set at run time.
you can set the x-frame-option in web config of the site you want to load in iframe like this
<httpProtocol>
<customHeaders>
<add name="X-Frame-Options" value="*" />
</customHeaders>
</httpProtocol>
Simple example in java
public class Driver {
static int x;
static int y;
public static void main(String[] args)
throws Exception {
System.out.println("using double pipe");
if(setX() || setY())
{System.out.println("x = "+x);
System.out.println("y = "+y);
}
System.out.println("using single pipe");
if(setX() | setY())
{System.out.println("x = "+x);
System.out.println("y = "+y);
}
}
static boolean setX(){
x=5;
return true;
}
static boolean setY(){
y=5;
return true;
}
}
output :
using double pipe
x = 5
y = 0
using single pipe
x = 5
y = 5
For example:
$(document).on('click','span.external-link',function(){
var t = $(this),
URL = t.attr('data-href');
$('<a href="'+ URL +'" target="_blank">External Link</a>')[0].click();
});
Working example.
Here is a functional ES6 way of iterating over a NodeList
. This method uses the Array
's forEach
like so:
Array.prototype.forEach.call(element.childNodes, f)
Where f
is the iterator function that receives a child nodes as it's first parameter and the index as the second.
If you need to iterate over NodeLists more than once you could create a small functional utility method out of this:
const forEach = f => x => Array.prototype.forEach.call(x, f);
// For example, to log all child nodes
forEach((item) => { console.log(item); })(element.childNodes)
// The functional forEach is handy as you can easily created curried functions
const logChildren = forEach((childNode) => { console.log(childNode); })
logChildren(elementA.childNodes)
logChildren(elementB.childNodes)
(You can do the same trick for map()
and other Array functions.)
These solutions didn't work with my datagrid. I was hoping they would. I don't really need Tab or Enter to move to the next input, column, row or whatever. I just need Enter to trigger .focusout or .change and my datagrid updates the database. So I added the "enter" class to the relevant text inputs and this did the trick for me:
$(function() {
if ($.browser.mozilla) {
$(".enter").keypress(checkForEnter);
} else {
$(".enter").keydown(checkForEnter);
}
});
function checkForEnter(event) {
if (event.keyCode == 13) {
$(".enter").blur();
}
}

Add store name to template like {% url 'app_name:url_name' %}

I believe that the correct answer has already been posted and accepted, yet there is an issue that I have experienced myself and that some others have mentioned here.
On certain platforms, various properties such as window dimensions (window.innerWidth
, window.innerHeight
) and the window.orientation
property will not be updated by the time that the event "orientationchange"
has fired. Many times, the property window.orientation
is undefined
for a few milliseconds after the firing of "orientationchange"
(at least it is in Chrome on iOS).
The best way that I found to handle this issue was:
var handleOrientationChange = (function() {
var struct = function(){
struct.parse();
};
struct.showPortraitView = function(){
alert("Portrait Orientation: " + window.orientation);
};
struct.showLandscapeView = function(){
alert("Landscape Orientation: " + window.orientation);
};
struct.parse = function(){
switch(window.orientation){
case 0:
//Portrait Orientation
this.showPortraitView();
break;
default:
//Landscape Orientation
if(!parseInt(window.orientation)
|| window.orientation === this.lastOrientation)
setTimeout(this, 10);
else
{
this.lastOrientation = window.orientation;
this.showLandscapeView();
}
break;
}
};
struct.lastOrientation = window.orientation;
return struct;
})();
window.addEventListener("orientationchange", handleOrientationChange, false);
I am checking to see if the orientation is either undefined or if the orientation is equal to the last orientation detected. If either is true, I wait ten milliseconds and then parse the orientation again. If the orientation is a proper value, I call the showXOrientation
functions. If the orientation is invalid, I continue to loop my checking function, waiting ten milliseconds each time, until it is valid.
Now, I would make a JSFiddle for this, as I usually did, but JSFiddle has not been working for me and my support bug for it was closed as no one else is reporting the same problem. If anyone else wants to turn this into a JSFiddle, please go ahead.
Thanks! I hope this helps!
You might want to consider NULL values as well. In your example, if the column notes has a null value, then the resulting value will be NULL. If you want the null values to behave as empty strings (so that the answer comes out 'SomeText'), then use the IsNull function:
Select IsNull(Cast(notes as nvarchar(4000)),'') + 'SomeText' From NotesTable a
Or You can use
grep -n . file1 |tail -LineNumberToStartWith|grep regEx
This will take care of numbering the lines in the file
grep -n . file1
This will print the last-LineNumberToStartWith
tail -LineNumberToStartWith
And finally it will grep your desired lines(which will include line number as in orignal file)
grep regEX
To change the integrated terminal on Windows, you just need to change the terminal.integrated.shell.windows
line:
"terminal.integrated.shell.windows": "C:\\Bin\\Cmder\\Cmder.exe"
setting to the User Settings document on the right if it's not already there. This is so you aren't editing the Default Setting directly, but instead adding to it.You can then access it with keys Ctrl+backtick by default.
You could use the INDIRECT function. This takes a string and converts it into a range
More info here
=INDIRECT("K"&A2)
But it's preferable to use INDEX as it is less volatile.
=INDEX(K:K,A2)
This returns a value or the reference to a value from within a table or range
More info here
Put either function into cell B2 and fill down.
It will be very helpful to get current date and time.
var date=new Date();
var today=new Date(date.getTime() - (date.getTimezoneOffset() * 60000)).toISOString().replace(/T/, ' ').replace(/\..+/, '');
Note: starting git1.8.3.2 (July 2013), the following command (mentioned above by Jeremy W Sherman) won't open an editor anymore:
git commit --allow-empty-message -m ''
See commit 25206778aac776fc6cc4887653fdae476c7a9b5a:
If an empty message is specified with the option
-m
of git commit then the editor is started.
That's unexpected and unnecessary.
Instead of using the length of the message string for checking if the user specified one, directly remember if the option-m
was given.
git 2.9 (June 2016) improves the empty message behavior:
See commit 178e814 (06 Apr 2016) by Adam Dinwoodie (me-and
).
See commit 27014cb (07 Apr 2016) by Jeff King (peff
).
(Merged by Junio C Hamano -- gitster
-- in commit 0709261, 22 Apr 2016)
commit
: do not ignore an empty message given by-m ''
- "
git commit --amend -m '' --allow-empty-message
", even though it looks strange, is a valid request to amend the commit to have no message at all.
Due to the misdetection of the presence of-m
on the command line, we ended up keeping the log messsage from the original commit.- "
git commit -m "$msg" -F file
" should be rejected whether$msg
is an empty string or not, but due to the same bug, was not rejected when$msg
is empty.- "
git -c template=file -m "$msg"
" should ignore the template even when$msg
is empty, but it didn't and instead used the contents from the template file.
SELECT id FROM TAG_TABLE WHERE 'aaaaaaaa' LIKE '%' || "tag_name" || '%';
tag_name
should be in quotation otherwise it will give error as tag_name doest not exist
Using setBackgroundResource()
method:
myImgView.setBackgroundResource(R.drawable.monkey);
you are putting that monkey in the background.
I suggest the use of setImageResource()
method:
myImgView.setImageResource(R.drawable.monkey);
or with setImageDrawable()
method:
myImgView.setImageDrawable(getResources().getDrawable(R.drawable.monkey));
getResources().getDrawable()
is now deprecated. This is an example how to use now:myImgView.setImageDrawable(getResources().getDrawable(R.drawable.monkey, getApplicationContext().getTheme()));
and how to validate for old API versions:
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
myImgView.setImageDrawable(getResources().getDrawable(R.drawable.monkey, getApplicationContext().getTheme()));
} else {
myImgView.setImageDrawable(getResources().getDrawable(R.drawable.monkey));
}
By deleting all emulator, sometime memory will not be reduce to our expectation. So open below mention path in you c drive
C:\Users{Username}.android\avd
In this avd folder, you can able to see all the avd's which you created earlier. So you need to delete all avd's that will remove all the unused spaces grab by your emulator's. Than create the fresh emulator for you works.
I like Jake's solution. The problem with no header is resolved by doing the following
xlWorkSheet.Cells[1, 1] = "Header 1";
xlWorkSheet.Cells[1, 2] = "Header 2";
xlWorkSheet.Cells[1, 3] = "Header 3";
of course this only works is you know what the headers should be ahead of time.
To define Global Variable you can make use of static Keyword
public class Example {
public static int a;
public static int b;
}
now you can access a and b from anywhere by calling
Example.a;
Example.b;
Install it by using this command:
pip install opencv-contrib-python

There is a way to do it slightly faster than in Yaroslav's answer by using get_operations. Here is a quick example:
import tensorflow as tf
a = tf.constant(1.3, name='const_a')
b = tf.Variable(3.1, name='variable_b')
c = tf.add(a, b, name='addition')
d = tf.multiply(c, a, name='multiply')
for op in tf.get_default_graph().get_operations():
print(str(op.name))
UPDATE t1
INNER JOIN t2 ON t2.t1_id = t1.id
INNER JOIN t3 ON t2.t3_id = t3.id
SET t1.a = 'something',
t2.b = 42,
t3.c = t2.c
WHERE t1.a = 'blah';
To see what this is going to update, you can convert this into a select statement, e.g.:
SELECT t2.t1_id, t2.t3_id, t1.a, t2.b, t2.c AS t2_c, t3.c AS t3_c
FROM t1
INNER JOIN t2 ON t2.t1_id = t1.id
INNER JOIN t3 ON t2.t3_id = t3.id
WHERE t1.a = 'blah';
An example using the same tables as the other answer:
SELECT Books.BookID, Orders.OrderID,
Orders.Quantity AS CurrentQuantity,
Orders.Quantity + 2 AS NewQuantity,
Books.InStock AS CurrentStock,
Books.InStock - 2 AS NewStock
FROM Books
INNER JOIN Orders ON Books.BookID = Orders.BookID
WHERE Orders.OrderID = 1002;
UPDATE Books
INNER JOIN Orders ON Books.BookID = Orders.BookID
SET Orders.Quantity = Orders.Quantity + 2,
Books.InStock = Books.InStock - 2
WHERE Orders.OrderID = 1002;
EDIT:
Just for fun, let's add something a bit more interesting.
Let's say you have a table of books
and a table of authors
. Your books
have an author_id
. But when the database was originally created, no foreign key constraints were set up and later a bug in the front-end code caused some books to be added with invalid author_id
s. As a DBA you don't want to have to go through all of these books
to check what the author_id
should be, so the decision is made that the data capturers will fix the books
to point to the right authors
. But there are too many books to go through each one and let's say you know that the ones that have an author_id
that corresponds with an actual author
are correct. It's just the ones that have nonexistent author_id
s that are invalid. There is already an interface for the users to update the book details and the developers don't want to change that just for this problem. But the existing interface does an INNER JOIN authors
, so all of the books with invalid authors are excluded.
What you can do is this: Insert a fake author record like "Unknown author". Then update the author_id
of all the bad records to point to the Unknown author. Then the data capturers can search for all books with the author set to "Unknown author", look up the correct author and fix them.
How do you update all of the bad records to point to the Unknown author? Like this (assuming the Unknown author's author_id
is 99999):
UPDATE books
LEFT OUTER JOIN authors ON books.author_id = authors.id
SET books.author_id = 99999
WHERE authors.id IS NULL;
The above will also update books
that have a NULL
author_id
to the Unknown author. If you don't want that, of course you can add AND books.author_id IS NOT NULL
.
First check for an error (N/A value) and then try the comparisation against cvErr(). You are comparing two different things, a value and an error. This may work, but not always. Simply casting the expression to an error may result in similar problems because it is not a real error only the value of an error which depends on the expression.
If IsError(ActiveWorkbook.Sheets("Publish").Range("G4").offset(offsetCount, 0).Value) Then
If (ActiveWorkbook.Sheets("Publish").Range("G4").offset(offsetCount, 0).Value <> CVErr(xlErrNA)) Then
'do something
End If
End If
Try the following:
#restart::before {
content: '';
display: block;
}
Try this...
var start = new Date(document.getElementById('Stardate').value);
var y = start.getFullYear();
To start only stopped containers:
docker start $(docker ps -a -q -f status=exited)
(On windows it works in Powershell).
Try setting the variable CMAKE_CXX_FLAGS
instead of CMAKE_C_FLAGS
:
set (CMAKE_CXX_FLAGS "-fexceptions")
The variable CMAKE_C_FLAGS
only affects the C compiler, but you are compiling C++ code.
Adding the flag to CMAKE_EXE_LINKER_FLAGS
is redundant.
This is not valid TypeScript code. You can not have method invocations in the body of a class.
// INVALID CODE
export class AppComponent {
public n: number = 1;
setTimeout(function() {
n = n + 10;
}, 1000);
}
Instead move the setTimeout
call to the constructor
of the class. Additionally, use the arrow function =>
to gain access to this
.
export class AppComponent {
public n: number = 1;
constructor() {
setTimeout(() => {
this.n = this.n + 10;
}, 1000);
}
}
In TypeScript, you can only refer to class properties or methods via this
. That's why the arrow function =>
is important.
SDK.INT is supported for Android 1.6 and up
SDK is supported for all versions
So I do:
String sdk_version_number = android.os.Build.VERSION.SDK;

Yes, \
in Python string literals denotes the start of an escape sequence. In your path you have a valid two-character escape sequence \a
, which is collapsed into one character that is ASCII Bell:
>>> '\a'
'\x07'
>>> len('\a')
1
>>> 'C:\meshes\as'
'C:\\meshes\x07s'
>>> print('C:\meshes\as')
C:\meshess
Other common escape sequences include \t
(tab), \n
(line feed), \r
(carriage return):
>>> list('C:\test')
['C', ':', '\t', 'e', 's', 't']
>>> list('C:\nest')
['C', ':', '\n', 'e', 's', 't']
>>> list('C:\rest')
['C', ':', '\r', 'e', 's', 't']
As you can see, in all these examples the backslash and the next character in the literal were grouped together to form a single character in the final string. The full list of Python's escape sequences is here.
There are a variety of ways to deal with that:
Python will not process escape sequences in string literals prefixed with r
or R
:
>>> r'C:\meshes\as'
'C:\\meshes\\as'
>>> print(r'C:\meshes\as')
C:\meshes\as
Python on Windows should handle forward slashes, too.
You could use os.path.join
...
>>> import os
>>> os.path.join('C:', os.sep, 'meshes', 'as')
'C:\\meshes\\as'
... or the newer pathlib
module
>>> from pathlib import Path
>>> Path('C:', '/', 'meshes', 'as')
WindowsPath('C:/meshes/as')
I am a little suprised to not see Floyd Warshall's algorithm mentioned here. This algorithm work's very much like Dijkstra's. It also has one very nice feature which is it allows you to compute as long as you would like to continue allowing more intermediate vertices. So it will naturally find the routes which use interstates or highways fairly quickly.
As commented by Chris, enums require much more memory on Android that adds up as they keep being used everywhere. You should try IntDef or StringDef instead, which use annotations so that the compiler validates passed values.
public abstract class ActionBar {
...
@IntDef({NAVIGATION_MODE_STANDARD, NAVIGATION_MODE_LIST, NAVIGATION_MODE_TABS})
@Retention(RetentionPolicy.SOURCE)
public @interface NavigationMode {}
public static final int NAVIGATION_MODE_STANDARD = 0;
public static final int NAVIGATION_MODE_LIST = 1;
public static final int NAVIGATION_MODE_TABS = 2;
@NavigationMode
public abstract int getNavigationMode();
public abstract void setNavigationMode(@NavigationMode int mode);
It can also be used as flags, allowing for binary composition (OR / AND operations).
EDIT: It seems that transforming enums into ints is one of the default optimizations in Proguard.
You can use the Request Desktop Site option from the app menu (to the right of the address bar) which will force the page to reload.
Simply tap it, wait for the refresh, then deselect it.

$('#refresh').html(div);
}else{
// show errors.
}
})
.fail(function() {
console.log("error");
})
.always(function() {
console.log("complete");

This is what I did: see on Codepen
var somedate = 1473888180593;

//var myStartDate = somedate - durationInMuntes;
myStartDate = new Date(dateAfterSubtracted('minutes', 100));

function dateAfterSubtracted(range, amount){
var now = new Date();
if(range === 'years'){
return now.setDate(now.getYear() - amount);
}
if(range === 'months'){
return now.setDate(now.getMonth() - amount);
}
if(range === 'days'){
return now.setDate(now.getDate() - amount);
}
if(range === 'hours'){

Close the first Bootstrap modal and open the new modal dynamically.

I am using such code in config.php:
$lang = 'ru'; // this language will be used if there is no any lang information from useragent (for example, from command line, wget, etc...
if (!empty($_SERVER['HTTP_ACCEPT_LANGUAGE'])) $lang = substr($_SERVER['HTTP_ACCEPT_LANGUAGE'],0,2);
$tmp_value = $_COOKIE['language'];
if (!empty($tmp_value)) $lang = $tmp_value;
switch ($lang)
{
case 'ru':
$config['language'] = 'russian';
setlocale(LC_ALL,'ru_RU.UTF-8');
break;
case 'uk':
$config['language'] = 'ukrainian';
setlocale(LC_ALL,'uk_UA.UTF-8');
break;
case 'foo':
$config['language'] = 'foo';
setlocale(LC_ALL,'foo_FOO.UTF-8');
break;
default:
$config['language'] = 'english';
setlocale(LC_ALL,'en_US.UTF-8');
break;
}
.... and then i'm using usualy internal mechanizm of CI
o, almost forget! in views i using buttons, which seting cookie 'language' with language, prefered by user.
So, first this code try to detect "preffered language" setted in user`s useragent (browser). Then code try to read cookie 'language'. And finaly - switch sets language for CI-application
One way to do this without moving anything is to take advantage of the fact that patch
can read git diff's (unified diffs basically)
git stash show -p | patch -p1 --verbose --dry-run
This will show you a step-by-step preview of what patch would ordinarily do. The added benefit to this is that patch won't prevent itself from writing the patch to the working tree either, if for some reason you just really need git to shut up about commiting-before-modifying, go ahead and remove --dry-run and follow the verbose instructions.
I have used this one successfully
System.IO.Path.GetDirectoryName(Process.GetCurrentProcess().MainModule.FileName)
It works even inside linqpad.
The question has already been answered but I thought I would also let you know that rather than using the native PHP $_POST I reccomend you use the CodeIgniter input class so your controller code would be
function post_action()
{
if($this->input->post('textbox') == "")
{
$message = "You can't send empty text";
}
else
{
$message = $this->input->post('textbox');
}
echo $message;
}
For those about to hack:
public static int GetNativeThreadId(Thread thread)
{
var f = typeof(Thread).GetField("DONT_USE_InternalThread",
BindingFlags.GetField | BindingFlags.NonPublic | BindingFlags.Instance);
var pInternalThread = (IntPtr)f.GetValue(thread);
var nativeId = Marshal.ReadInt32(pInternalThread, (IntPtr.Size == 8) ? 548 : 348); // found by analyzing the memory
return nativeId;
}
If the point is simply to make the text inside the element invisible, set the color attribute to have 0 opacity using a rgba value such as color:rgba(0,0,0,0);
clean and simple.
If you have multiple markers you can use this simple solution to close a previously opened marker when clicking a new marker:
var infowindow = new google.maps.InfoWindow({
maxWidth: (window.innerWidth - 160),
content: content
});
marker.infowindow = infowindow;
var openInfoWindow = '';
marker.addListener('click', function (map, marker) {
if (openInfoWindow) {
openInfoWindow.close();
}
openInfoWindow = this.infowindow;
this.infowindow.open(map, this);
});
display: inline-block
is your friend you just need all three parts of the construct - before, the "block", after - to be one, then you can vertically align them all to the middle:
(it looks like your picture anyway ;))
CSS:
p, div {
display: inline-block;
vertical-align: middle;
}
p, div {
display: inline !ie7; /* hack for IE7 and below */
}
table {
background: #000;
color: #fff;
font-size: 16px;
font-weight: bold; margin: 0 10px;
}
td {
padding: 5px;
text-align: center;
}
HTML:
<p>some text</p>
<div>
<table summary="">
<tr><td>A</td></tr>
<tr><td>B</td></tr>
<tr><td>C</td></tr>
<tr><td>D</td></tr>
</table>
</div>
<p>continues afterwards</p>

I used preg_match to do it.
In my case, I had a string containing exactly one <img>
tag (and no other markup) that I got from Wordpress and I was trying to get the src
attribute so I could run it through timthumb.
// get the featured image
$image = get_the_post_thumbnail($photos[$i]->ID);
// get the src for that image
$pattern = '/src="([^"]*)"/';
preg_match($pattern, $image, $matches);
$src = $matches[1];
unset($matches);
In the pattern to grab the title or the alt, you could simply use $pattern = '/title="([^"]*)"/';
to grab the title or $pattern = '/title="([^"]*)"/';
to grab the alt. Sadly, my regex isn't good enough to grab all three (alt/title/src) with one pass though.
Well, both will clean. That means they'll remove the target folder. The real question is what's the difference between package and install?
package
will compile your code and also package it. For example, if your pom says the project is a jar, it will create a jar for you when you package it and put it somewhere in the target directory (by default).
install
will compile and package, but it will also put the package in your local repository. This will make it so other projects can refer to it and grab it from your local repository.
You can't.
function(){
function my_fun(){
/.. some operations ../
}
}
That is a closure. my_fun()
is defined only inside of that anonymous function. You can only call my_fun()
if you declare it at the correct level of scope, i.e., globally.
$(function () {/* something */})
is an IIFE, meaning it executes immediately when the DOM is ready. By declaring my_fun()
inside of that anonymous function, you prevent the rest of the script from "seeing" it.
Of course, if you want to run this function when the DOM has fully loaded, you should do the following:
function my_fun(){
/* some operations */
}
$(function(){
my_fun(); //run my_fun() ondomready
});
// just js
function js_fun(){
my_fun(); //== call my_fun() again
}
Winston is strong choice for most of the developers. I have been using winston for long. Recently I used winston with with papertrail which takes the application logging to next level.
Here is a nice screenshot from their site.
How its useful
you can manage logs from different systems at one place. this can be very useful when you have two backend communicating and can see logs from both at on place.
Logs are live. you can see realtime logs of your production server.
Powerful search and filter
you can create alerts to send you email if it encounters specific text in log.
and you can find more http://help.papertrailapp.com/kb/how-it-works/event-viewer/
A simple configuration using winston
,winston-express
and winston-papertrail
node modules.
import winston from 'winston';
import expressWinston from 'express-winston';
//
// Requiring `winston-papertrail` will expose
// `winston.transports.Papertrail`
//
require('winston-papertrail').Papertrail;
// create winston transport for Papertrail
var winstonPapertrail = new winston.transports.Papertrail({
host: 'logsX.papertrailapp.com',
port: XXXXX
});
app.use(expressWinston.logger({
transports: [winstonPapertrail],
meta: true, // optional: control whether you want to log the meta data about the request (default to true)
msg: "HTTP {{req.method}} {{req.url}}", // optional: customize the default logging message. E.g. "{{res.statusCode}} {{req.method}} {{res.responseTime}}ms {{req.url}}"
expressFormat: true, // Use the default Express/morgan request formatting. Enabling this will override any msg if true. Will only output colors with colorize set to true
colorize: true, // Color the text and status code, using the Express/morgan color palette (text: gray, status: default green, 3XX cyan, 4XX yellow, 5XX red).
ignoreRoute: function (req, res) { return false; } // optional: allows to skip some log messages based on request and/or response
}));
Unless there is a definite requirement of writing on external storage, you can always choose to save files in app directory. In my case I had to save files and after wasting 2 to 3 days I found out if I change the storage path from
Environment.getExternalStorageDirectory()
to
getApplicationContext().getFilesDir().getPath() //which returns the internal app files directory path
it works like charm on all the devices. This is because for writing on External storage you need extra permissions but writing in internal app directory is simple.
I was ultimately able to resolve the solution by setting the column type in the flat file connection to be of type "database date [DT_DBDATE]"
Apparently the differences between these date formats are as follow:
DT_DATE A date structure that consists of year, month, day, and hour.
DT_DBDATE A date structure that consists of year, month, and day.
DT_DBTIMESTAMP A timestamp structure that consists of year, month, hour, minute, second, and fraction
By changing the column type to DT_DBDATE the issue was resolved - I attached a Data Viewer and the CYCLE_DATE value was now simply "12/20/2010" without a time component, which apparently resolved the issue.
In my case, I actually change the package name, and it started causing this issue.
I have tried many trick but here I am describing what actually worked for me.
Make sure your activity name is correct also make sure the package name is correct in manifest file.
This is the most simple solution for me:
$tStamp = Get-Date -format yyyy_MM_dd_HHmmss
$tStamp = Get-Date (get-date).AddMonths(6).Date -Format yyyyMMdd
So, the concept of a "wildcard" in Regular Expressions works a bit differently. In order to match "any character" you would use "." The "*" modifier means, match any number of times.
This might be more desirable, that is use float instead
SELECT fullName, CAST(totalBal as float) totalBal FROM client_info ORDER BY totalBal DESC
JavaScript has associative arrays.
Here is a working snippet.
<script type="text/javascript">
var myArray = [];
myArray['thank'] = 'you';
myArray['no'] = 'problem';
console.log(myArray);
</script>

They are simply called objects.
Please check that the function you are importing and the one that you have declared in the same file do not have the same name.
I will give you an example for this error. In express JS (using ES6), consider the following scenario:
import {getAllCall} from '../../services/calls';
let getAllCall = () => {
return getAllCall().then(res => {
//do something here
})
}
module.exports = {
getAllCall
}
The above scenario will cause infamous RangeError: Maximum call stack size exceeded error because the function keeps calling itself so many times that it runs out of maximum call stack.
Most of the times the error is in code (like the one above). Other way of resolving is manually increasing the call stack. Well, this works for certain extreme cases, but it is not recommended.
Hope my answer helped you.
td
height to less than the natural height of its contentSince table cells want to be at least big enough to encase their content, if the content has no apparent height, the cells can be arbitrarily resized.
By resizing the cells, we can control the row height.
One way to do this, is to set the content with an absolute
position within the relative
cell, and set the height
of the cell, and the left
and top
of the content.

The table-layout
property
The second table in the snippet above has table-layout: fixed
applied, which causes cells to be given equal width, regardless of their content, within the parent.
According to caniuse.com, there are no significant compatibility issues regarding the use of table-layout
as of Sept 12, 2019.
Or simply apply width
to specific cells as in the third table.
These methods allow the cell containing the effectively sizeless content created by applying position: absolute
to be given some arbitrary girth.
I really should have thought of this from the start; we can manipulate block level table cell content in all the usual ways, and without completely destroying the content's natural size with position: absolute
, we can leave the table to figure out what the width should be.

break
will stop the current loop (or pass an integer to tell it how many loops to break from).
continue
will stop the current iteration and start the next one.
One way is to create a Spliterator
from the Iterator
and use that as a basis for your stream:
Iterator<String> sourceIterator = Arrays.asList("A", "B", "C").iterator();
Stream<String> targetStream = StreamSupport.stream(
Spliterators.spliteratorUnknownSize(sourceIterator, Spliterator.ORDERED),
false);
An alternative which is maybe more readable is to use an Iterable
- and creating an Iterable
from an Iterator
is very easy with lambdas because Iterable
is a functional interface:
Iterator<String> sourceIterator = Arrays.asList("A", "B", "C").iterator();
Iterable<String> iterable = () -> sourceIterator;
Stream<String> targetStream = StreamSupport.stream(iterable.spliterator(), false);
