Spring MVC is deeply integreated in Spring, Struts MVC is not.
Use component scanning as given below, if com.project.action.PasswordHintAction
is annotated with stereotype annotations
<context:component-scan base-package="com.project.action"/>
EDIT
I see your problem, in PasswordHintActionTest
you are autowiring PasswordHintAction
. But you did not create bean configuration for PasswordHintAction
to autowire. Add one of stereotype annotation(@Component, @Service, @Controller
) to PasswordHintAction
like
@Component
public class PasswordHintAction extends BaseAction {
private static final long serialVersionUID = -4037514607101222025L;
private String username;
or create xml configuration in applicationcontext.xml
like
<bean id="passwordHintAction" class="com.project.action.PasswordHintAction" />
I was having this problem too. For me, I couldn't start/stop openfire (it said it was stopped, but everything was still running)
sudo /etc/init.d/openfire stop
sudo /etc/init.d/openfire start
Also, restarting apache did not help either
sudo /etc/init.d/apache2 restart
The errors were inside:
/opt/openfire/logs/stderror.log
Error creating server listener on port 5269: Address already in use
Error creating server listener on port 5222: Address already in use
The way I fixed this, I had to actually turn off the server inside the admin area for my host.
var that = this; // this is a form
(new Thread(()=> {
var action= new Action(() => {
something
}));
if(!that.IsDisposed)
{
if(that.IsHandleCreated)
{
//if (that.InvokeRequired)
that.BeginInvoke(action);
//else
// action.Invoke();
}
else
that.HandleCreated+=(sender,event) => {
action.Invoke();
};
}
})).Start();
You can hide a CommandField or ButtonField based on the position (index) in the GridView.
For example, if your CommandField is in the first position (index = 0), you can hide it adding the following code in the event RowDataBound of the GridView:
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
((System.Web.UI.Control)e.Row.Cells[0].Controls[0]).Visible = false;
}
}
Try adding the following tags in the wwwroot
folder web.config file. These tags should be added as a child of the configuration tags as below.
-configuration-
--system.webServer--
---validation validateIntegratedModeConfiguration="false" ---
--/system.webServer--
-/configuration-
Make sure you are loading those modules (myApp.services and myApp.directives) as dependencies of your main app module, like this:
angular.module('myApp', ['myApp.directives', 'myApp.services']);

I finally found out how to do this! Basically you need to run adb shell
first and then while you're in the shell run su
, which will switch the shell to run as root!
$: adb shell
$: su
The one problem I still have is that sqlite3 is not installed so the command is not recognized.
Here's what you can do for say yyyy-mm-dd comparison:
GregorianCalendar gc= new GregorianCalendar();
gc.setTimeInMillis(System.currentTimeMillis());
gc.roll(GregorianCalendar.DAY_OF_MONTH, true);
Date d1 = new Date();
Date d2 = gc.getTime();
SimpleDateFormat sf= new SimpleDateFormat("yyyy-MM-dd");
if(sf.format(d2).hashCode() < sf.format(d1).hashCode())
{
System.out.println("date 2 is less than date 1");
}
else
{
System.out.println("date 2 is equal or greater than date 1");
}
Most easiest way
I can see the question is answered , I'm giving this answer for the ones who is having this question in future
Its not good practise to code inline css , and also ID for all inner div's , always try to use class for styling .Using inline css is a very bad practise if you are trying to be a professional web designer.
here in your question I have given a wrapper class for the parent div and all the inside div's are child div's in css you can call inner div's using nth-child selector.
I want to point few things here
1 - Do not use inline css ( it is very bad practise )
2 - Try to use classes instead of id's because if you give an id you can use it only once, but if you use a class you can use it many times and also you can style of them using that class so you write less code.

Use DATESTR
>> datestr(40189)
ans =
12-Jan-0110
Unfortunately, Excel starts counting at 1-Jan-1900. Find out how to convert serial dates from Matlab to Excel by using DATENUM
>> datenum(2010,1,11)
ans =
734149
>> datenum(2010,1,11)-40189
ans =
693960
>> datestr(40189+693960)
ans =
11-Jan-2010
In other words, to convert any serial Excel date, call
datestr(excelSerialDate + 693960)
EDIT
To get the date in mm/dd/yyyy format, call datestr
with the specified format
excelSerialDate = 40189;
datestr(excelSerialDate + 693960,'mm/dd/yyyy')
ans =
01/11/2010
Also, if you want to get rid of the leading zero for the month, you can use REGEXPREP to fix things
excelSerialDate = 40189;
regexprep(datestr(excelSerialDate + 693960,'mm/dd/yyyy'),'^0','')
ans =
1/11/2010
Just restating what Tomasz said.
There are many examples of FOO__in=...
style filters in the many-to-many and many-to-one tests. Here is syntax for your specific problem:
users_in_1zone = User.objects.filter(zones__id=<id1>)
# same thing but using in
users_in_1zone = User.objects.filter(zones__in=[<id1>])
# filtering on a few zones, by id
users_in_zones = User.objects.filter(zones__in=[<id1>, <id2>, <id3>])
# and by zone object (object gets converted to pk under the covers)
users_in_zones = User.objects.filter(zones__in=[zone1, zone2, zone3])
The double underscore (__) syntax is used all over the place when working with querysets.
Using Java 8:
private static Comparator<String> nullSafeStringComparator = Comparator
.nullsFirst(String::compareToIgnoreCase);
private static Comparator<Metadata> metadataComparator = Comparator

public int compareTo(Metadata that) {
return metadataComparator.compare(this, that);

See screenshots below from Postman:
When calling a function that is declared with throws
in Swift, you must annotate the function call site with try
or try!
. For example, given a throwing function:
func willOnlyThrowIfTrue(value: Bool) throws {
if value { throw someError }
}
this function can be called like:
func foo(value: Bool) throws {
try willOnlyThrowIfTrue(value)
}
Here we annotate the call with try
, which calls out to the reader that this function may throw an exception, and any following lines of code might not be executed. We also have to annotate this function with throws
, because this function could throw an exception (i.e., when willOnlyThrowIfTrue()
throws, then foo
will automatically rethrow the exception upwards.
If you want to call a function that is declared as possibly throwing, but which you know will not throw in your case because you're giving it correct input, you can use try!
.
func bar() {
try! willOnlyThrowIfTrue(false)
}
This way, when you guarantee that code won't throw, you don't have to put in extra boilerplate code to disable exception propagation.
try!
is enforced at runtime: if you use try!
and the function does end up throwing, then your program's execution will be terminated with a runtime error.
Most exception handling code should look like the above: either you simply propagate exceptions upward when they occur, or you set up conditions such that otherwise possible exceptions are ruled out. Any clean up of other resources in your code should occur via object destruction (i.e. deinit()
), or sometimes via defer
ed code.
func baz(value: Bool) throws {
var filePath = NSBundle.mainBundle().pathForResource("theFile", ofType:"txt")
var data = NSData(contentsOfFile:filePath)
try willOnlyThrowIfTrue(value)
// data and filePath automatically cleaned up, even when an exception occurs.
}
If for whatever reason you have clean up code that needs to run but isn't in a deinit()
function, you can use defer
.
func qux(value: Bool) throws {
defer {
print("this code runs when the function exits, even when it exits by an exception")
}
try willOnlyThrowIfTrue(value)
}
Most code that deals with exceptions simply has them propagate upward to callers, doing cleanup on the way via deinit()
or defer
. This is because most code doesn't know what to do with errors; it knows what went wrong, but it doesn't have enough information about what some higher level code is trying to do in order to know what to do about the error. It doesn't know if presenting a dialog to the user is appropriate, or if it should retry, or if something else is appropriate.
Higher level code, however, should know exactly what to do in the event of any error. So exceptions allow specific errors to bubble up from where they initially occur to the where they can be handled.
Handling exceptions is done via catch
statements.
func quux(value: Bool) {
do {
try willOnlyThrowIfTrue(value)
} catch {
// handle error
}
}
You can have multiple catch statements, each catching a different kind of exception.
do {
try someFunctionThatThowsDifferentExceptions()
} catch MyErrorType.errorA {
// handle errorA
} catch MyErrorType.errorB {
// handle errorB
} catch {
// handle other errors
}
For more details on best practices with exceptions, see http://exceptionsafecode.com/. It's specifically aimed at C++, but after examining the Swift exception model, I believe the basics apply to Swift as well.
For details on the Swift syntax and error handling model, see the book The Swift Programming Language (Swift 2 Prerelease).
The biggest benefit of using IoC containers for me (personally, I use Ninject) has been to eliminate the passing around of settings and other sorts of global state objects.
I don't program for the web, mine is a console application and in many places deep in the object tree I need to have access to the settings or metadata specified by the user that are created on a completely separate branch of the object tree. With IoC I simply tell Ninject to treat the Settings as a singleton (because there is always only one instance of them), request the Settings or Dictionary in the constructor and presto ... they magically appear when I need them!
Without using an IoC container I would have to pass the settings and/or metadata down through 2, 3, ..., n objects before it was actually used by the object that needed it.
There are many other benefits to DI/IoC containers as other people have detailed here and moving from the idea of creating objects to requesting objects can be mind-bending, but using DI was very helpful for me and my team so maybe you can add it to your arsenal!
Try this:
$old_date = Date_create("2010-04-19 18:31:27");
$new_date = Date_format($old_date, "d/m/Y");
In docker image of PHP-FPM, i've see such approach:
# cat /usr/local/etc/php-fpm.d/docker.conf
[global]
error_log = /proc/self/fd/2
[www]
; if we send this to /proc/self/fd/1, it never appears
access.log = /proc/self/fd/2
You can try something like this:
Inside customview constructor:
mContext = context;
Next inside customview you can call:
((MainActivity) mContext).updateText( text );
Inside MainAcivity
define:
public void updateText(final String text) {
TextView txtView = (TextView) findViewById(R.id.text);
txtView.setText(text);
}
It works for me.
If you only want the mean of the weight
column, select the column (which is a Series) and call .mean()
:
In [479]: df
Out[479]:
ID birthyear weight
0 619040 1962 0.123123
1 600161 1963 0.981742
2 25602033 1963 1.312312
3 624870 1987 0.942120
In [480]: df["weight"].mean()
Out[480]: 0.83982437500000007
this works only if WebResponse is a HttpWebResponse.
try
{

}
catch (System.Net.WebException exc)
{
var webResponse = exc.Response as System.Net.HttpWebResponse;
if (webResponse != null &&
webResponse.StatusCode == System.Net.HttpStatusCode.Unauthorized)
{
MessageBox.Show("401");
}
else
throw;
}
One solution would be to use the plt.legend
function, even if you don't want an actual legend. You can specify the placement of the legend box by using the loc
keyterm. More information can be found at this website but I've also included an example showing how to place a legend:
ax.scatter(xa,ya, marker='o', s=20, c="lightgreen", alpha=0.9)
ax.scatter(xb,yb, marker='o', s=20, c="dodgerblue", alpha=0.9)
ax.scatter(xc,yc marker='o', s=20, c="firebrick", alpha=1.0)
ax.scatter(xd,xd,xd, marker='o', s=20, c="goldenrod", alpha=0.9)
line1 = Line2D(range(10), range(10), marker='o', color="goldenrod")
line2 = Line2D(range(10), range(10), marker='o',color="firebrick")
line3 = Line2D(range(10), range(10), marker='o',color="lightgreen")
line4 = Line2D(range(10), range(10), marker='o',color="dodgerblue")
plt.legend((line1,line2,line3, line4),('line1','line2', 'line3', 'line4'),numpoints=1, loc=2)
Note that because loc=2
, the legend is in the upper-left corner of the plot. And if the text overlaps with the plot, you can make it smaller by using legend.fontsize
, which will then make the legend smaller.
Try this. Copy this into a batch file - such as send.bat - and then simply run send.bat
to send the message from the temperature program to the prismcom program.
temperature.exe > msg.txt
set /p msg= < msg.txt
prismcom.exe usb "%msg%"
The best option, in my opinion, is to use the Value
property for the ListItem
, which is available in the RadioButtonList
.
I must remark that ListItem
does NOT have an ID property.
So, in your case, to select the second element (option2) that would be:
// SelectedValue expects a string
radio1.SelectedValue = "1";
Alternatively, yet in very much the same vein you may supply an int to SelectedIndex.
// SelectedIndex expects an int, and are identified in the same order as they are added to the List starting with 0.
radio1.SelectedIndex = 1;
The optimiser will judge if the use of your index will make your query run faster, and if it is, it will use the index.
Depending on your RDBMS you can force the use of an index, although it is not recommended unless you know what you are doing.
In general you should index columns that you use in table join's and where statements
I know this is old and answered, but here is another way to do it. Particularly if you don't want the UTF8 BOM at the start of your string and you want the text indented:
using (var ms = new MemoryStream())
using (var x = new XmlTextWriter(ms, new UTF8Encoding(false))
{ Formatting = Formatting.Indented })
{
// ...
return Encoding.UTF8.GetString(ms.ToArray());
}
I have faced the same problem in cPanel

RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^ index.php [L]
Using 400
status codes for any other purpose than indicating that the request is malformed is just plain wrong.
If the request payload contains a byte-sequence that could not be parsed as application/json
(if the server expects that dataformat), the appropriate status code is 415
:
The server is refusing to service the request because the entity of the request is in a format not supported by the requested resource for the requested method.
If the request payload is syntactically correct but semantically incorrect, the non-standard 422
response code may be used, or the standard 403
status code:
The server understood the request, but is refusing to fulfill it. Authorization will not help and the request SHOULD NOT be repeated.
You can also run your app like any other console applications but only after the publish.
Let's suppose you have the simple console app named MyTestConsoleApp. Open the package manager console and run the following command:
dotnet publish -c Debug -r win10-x64
-c flag mean that you want to use the debug configuration (in other case you should use Release value) - r flag mean that your application will be runned on Windows platform with x64 architecture.
When the publish procedure will be finished your will see the *.exe file located in your bin/Debug/publish directory.
Now you can call it via command line tools. So open the CMD window (or terminal) move to the directory where your *.exe file is located and write the next command:
>> MyTestConsoleApp.exe argument-list
For example:
>> MyTestConsoleApp.exe --input some_text -r true
Expanding on Brian Camire's Answer:
Using =MEDIAN(IF($A$1:$A$6="Airline",$B$1:$B$6,""))
with CTRL+SHIFT+ENTER
will include blank cells in the calculation. Blank cells will be evaluated as 0 which results in a lower median value. The same is true if using the average funtion. If you don't want to include blank cells in the calculation, use a nested if statement like so:
=MEDIAN(IF($A$1:$A$6="Airline",IF($B$1:$B$6<>"",$B$1:$B$6)))
Don't forget to press CTRL+SHIFT+ENTER
to treat the formula as an "array formula".
As Baptiste said, you need to specify the data argument at the geom level. Either
#df1 is the default dataset for all geoms
(plot1 <- ggplot(df1, aes(v, p)) +
geom_point() +
geom_step(data = df2)
)
or
#No default; data explicitly specified for each geom
(plot2 <- ggplot(NULL, aes(v, p)) +
geom_point(data = df1) +
geom_step(data = df2)
)
You don't need to use only identifier as elements locators. You can use a few ways to find an element. Read this article and choose the best for you.
You don't want to have the collision check code inside the painting code. The painting needs to be fast. Collision can go in the game loop. Therefore you need an internal representation of the objects independent of their sprites.
d = {'key1': 1,'key2': 14,'key3': 47}
sum1 = sum(d[item] for item in d)
print(sum1)
you can do it using the for loop
String labelText ="<html>Name :"+name+"<br>Surname :"+surname+"<br>Gender :"+gender+"</html>";
JLabel label=new JLabel(labelText);
label.setVisible(true);
label.setBounds(10, 10,300, 100);
dialog.add(label);
I solved the error ERROR 2006 (HY000) at line 97: MySQL server has gone away
and successfully migrated a >5GB sql file by performing these two steps in order:
Created /etc/my.cnf as others have recommended, with the following contents:
[mysql]
connect_timeout = 43200
max_allowed_packet = 2048M
net_buffer_length = 512M
debug-info = TRUE
Appending the flags --force --wait --reconnect
to the command (i.e. mysql -u root -p -h localhost my_db < file.sql --verbose --force --wait --reconnect
).
Important Note: It was necessary to perform both steps, because if I didn't bother making the changes to /etc/my.cnf file as well as appending those flags, some of the tables were missing after the import.
System used: OSX El Capitan 10.11.5; mysql Ver 14.14 Distrib 5.5.51 for osx10.8 (i386)
Very strange that the very convenient
M-x eval-buffer
is not mentioned here.
It immediately evaluates all code in the buffer, its the quickest method, if your .emacs
is idempotent.
sometimes you need to set Padding, not Margin to make space between items smaller than default
The standard MIME type is application/pdf
. The assignment is defined in RFC 3778, The application/pdf Media Type, referenced from the MIME Media Types registry.
MIME types are controlled by a standards body, The Internet Assigned Numbers Authority (IANA). This is the same organization that manages the root name servers and the IP address space.
The use of x-pdf
predates the standardization of the MIME type for PDF. MIME types in the x-
namespace are considered experimental, just as those in the vnd.
namespace are considered vendor-specific. x-pdf
might be used for compatibility with old software.
I had this issue while trying to use a db_dump to restore a db. I normally use dbeaver to restore- however received a psql dump, so had to figure out a method to restore using the docker container.
The methodology recommended by Forth and edited by Soviut worked for me:
cat your_dump.sql | docker exec -i your-db-container psql -U postgres -d dbname
(since this was a single db dump and not multiple db's i included the name)
However, in order to get this to work, I had to also go into the virtualenv that the docker container and project were in. This eluded me for a bit before figuring it out- as I was receiving the following docker error.
read unix @->/var/run/docker.sock: read: connection reset by peer
This can be caused by the file /var/lib/docker/network/files/local-kv.db .I don't know the accuracy of this statement: but I believe I was seeing this as I do not user docker locally, so therefore did not have this file, which it was looking for, using Forth's answer.
I then navigated to correct directory (with the project) activated the virtualenv and then ran the accepted answer. Boom, worked like a top. Hope this helps someone else out there!
If you really want to use Deleted, you'd have to make your foreign keys nullable, but then you'd end up with orphaned records (which is one of the main reasons you shouldn't be doing that in the first place). So just use Remove()
ObjectContext.DeleteObject(entity) marks the entity as Deleted in the context. (It's EntityState is Deleted after that.) If you call SaveChanges afterwards EF sends a SQL DELETE statement to the database. If no referential constraints in the database are violated the entity will be deleted, otherwise an exception is thrown.
EntityCollection.Remove(childEntity) marks the relationship between parent and childEntity as Deleted. If the childEntity itself is deleted from the database and what exactly happens when you call SaveChanges depends on the kind of relationship between the two:
A thing worth noting is that setting .State = EntityState.Deleted
does not trigger automatically detected change. (archive)
Firstly a warning: you should never tinker with DOM that is managed by React, which you are doing by calling ReactDOM.render(<SampleComponent ... />);
With React, you should use SampleComponent directly in the main App.
var App = require('./App.js');
var SampleComponent = require('./SampleComponent.js');
ReactDOM.render(<App/>, document.body);
The content of your Component is irrelevant, but it should be used like this:
var App = React.createClass({
render: function() {
return (
<div>
<h1>App main component! </h1>
<SampleComponent name="SomeName"/>
</div>
);
}
});
You can then extend your app component to use a list.
var App = React.createClass({
render: function() {
var componentList = [
<SampleComponent name="SomeName1"/>,
<SampleComponent name="SomeName2"/>
]; // Change this to get the list from props or state
return (
<div>
<h1>App main component! </h1>
{componentList}
</div>
);
}
});
I would really recommend that you look at the React documentation then follow the "Get Started" instructions. The time you spend on that will pay off later.

If these don't depend on the class or instance, then just make them a function.
As this would seem like the obvious solution. Unless of course you think it's going to need to be overwritten, subclassed, etc. If so, then the previous answers are the best bet. Fingers crossed I won't get marked down for merely offering an alternative solution that may or may not fit someone’s needs ;).
As the correct answer will depend on the use case of the code in question ;)
XHTML Won't Validate if the script is anywhere other than within the head element. turns out it can be everywhere.
You can defer the execution with something like jQuery so it doesn't matter where it's placed (except for a small performance hit during parsing).
I added "\Anaconda3_64\" and "\Anaconda3_64\Scripts\" to the PATH variable. Then I can use conda from powershell or command prompt.

CREATE INDEX reports_data_gin_idx ON reports
USING gin ((data->'objects') jsonb_path_ops);
SELECT * FROM reports WHERE data->'objects' @> '[{"src":"foo.png"}]';
Since the key objects
holds a JSON array, we need to match the structure in the search term and wrap the array element into square brackets, too. Drop the array brackets when searching a plain record.
More explanation and options:
json
in Postgres 9.3+Unnest the JSON array with the function json_array_elements()
in a lateral join in the FROM
clause and test for its elements:
SELECT data::text, obj
FROM reports r, json_array_elements(r.data#>'{objects}') obj
WHERE obj->>'src' = 'foo.png';
The CTE (WITH
query) just substitutes for a table reports
.
Or, equivalent for just a single level of nesting:
SELECT *
FROM reports r, json_array_elements(r.data->'objects') obj
WHERE obj->>'src' = 'foo.png';
->>
, ->
and #>
operators are explained in the manual.
Both queries use an implicit JOIN LATERAL
.

You cannot include style directives in GFM.
The most complete documentation/example is "Markdown Cheatsheet", and it illustrates that this element <style>
is missing.
If you manage to include your text in one of the GFM elements, then you can play with a github.css stylesheet in order to colors that way, meaning to color using inline CSS style directives, referring to said css stylesheet.
select time, coalesce(count(case when activities = 3 then 1 end), 0) as count
from MyTable
group by time
Output:
| TIME | COUNT |
-----------------
| 13:00 | 2 |
| 13:15 | 2 |
| 13:30 | 0 |
| 13:45 | 1 |
If you want to count all the activities in one query, you can do:
select time,
coalesce(count(case when activities = 1 then 1 end), 0) as count1,
coalesce(count(case when activities = 2 then 1 end), 0) as count2,
coalesce(count(case when activities = 3 then 1 end), 0) as count3,
coalesce(count(case when activities = 4 then 1 end), 0) as count4,
coalesce(count(case when activities = 5 then 1 end), 0) as count5
from MyTable
group by time
The advantage of this over grouping by activities, is that it will return a count of 0 even if there are no activites of that type for that time segment.
Of course, this will not return rows for time segments with no activities of any type. If you need that, you'll need to use a left join with table that lists all the possible time segments.
The solution for me was in the instalation of php, Dont have correctly configured the environment variable and the php.ini file. Doing this two correction an uncomented de line of extension = pdo_mysql.so

It should suffice to say whether bcrypt or SHA-512 (in the context of an appropriate algorithm like PBKDF2) is good enough. And the answer is yes, either algorithm is secure enough that a breach will occur through an implementation flaw, not cryptanalysis.
If you insist on knowing which is "better", SHA-512 has had in-depth reviews by NIST and others. It's good, but flaws have been recognized that, while not exploitable now, have led to the the SHA-3 competition for new hash algorithms. Also, keep in mind that the study of hash algorithms is "newer" than that of ciphers, and cryptographers are still learning about them.
Even though bcrypt as a whole hasn't had as much scrutiny as Blowfish itself, I believe that being based on a cipher with a well-understood structure gives it some inherent security that hash-based authentication lacks. Also, it is easier to use common GPUs as a tool for attacking SHA-2–based hashes; because of its memory requirements, optimizing bcrypt requires more specialized hardware like FPGA with some on-board RAM.
Note: bcrypt is an algorithm that uses Blowfish internally. It is not an encryption algorithm itself. It is used to irreversibly obscure passwords, just as hash functions are used to do a "one-way hash".
Cryptographic hash algorithms are designed to be impossible to reverse. In other words, given only the output of a hash function, it should take "forever" to find a message that will produce the same hash output. In fact, it should be computationally infeasible to find any two messages that produce the same hash value. Unlike a cipher, hash functions aren't parameterized with a key; the same input will always produce the same output.
If someone provides a password that hashes to the value stored in the password table, they are authenticated. In particular, because of the irreversibility of the hash function, it's assumed that the user isn't an attacker that got hold of the hash and reversed it to find a working password.
Now consider bcrypt. It uses Blowfish to encrypt a magic string, using a key "derived" from the password. Later, when a user enters a password, the key is derived again, and if the ciphertext produced by encrypting with that key matches the stored ciphertext, the user is authenticated. The ciphertext is stored in the "password" table, but the derived key is never stored.
In order to break the cryptography here, an attacker would have to recover the key from the ciphertext. This is called a "known-plaintext" attack, since the attack knows the magic string that has been encrypted, but not the key used. Blowfish has been studied extensively, and no attacks are yet known that would allow an attacker to find the key with a single known plaintext.
So, just like irreversible algorithms based cryptographic digests, bcrypt produces an irreversible output, from a password, salt, and cost factor. Its strength lies in Blowfish's resistance to known plaintext attacks, which is analogous to a "first pre-image attack" on a digest algorithm. Since it can be used in place of a hash algorithm to protect passwords, bcrypt is confusingly referred to as a "hash" algorithm itself.
Assuming that rainbow tables have been thwarted by proper use of salt, any truly irreversible function reduces the attacker to trial-and-error. And the rate that the attacker can make trials is determined by the speed of that irreversible "hash" algorithm. If a single iteration of a hash function is used, an attacker can make millions of trials per second using equipment that costs on the order of $1000, testing all passwords up to 8 characters long in a few months.
If however, the digest output is "fed back" thousands of times, it will take hundreds of years to test the same set of passwords on that hardware. Bcrypt achieves the same "key strengthening" effect by iterating inside its key derivation routine, and a proper hash-based method like PBKDF2 does the same thing; in this respect, the two methods are similar.
So, my recommendation of bcrypt stems from the assumptions 1) that a Blowfish has had a similar level of scrutiny as the SHA-2 family of hash functions, and 2) that cryptanalytic methods for ciphers are better developed than those for hash functions.
Below code(jQuery.isEmptyObject(anyObject) function is already provided) works perfectly fine, no need to write one of your own.

The recommended way to create random integers with NumPy these days is to use numpy.random.Generator.integers
. (documentation)

One way to handle this is to create a new BufferedImage, and tell it's graphics object to draw your scaled image into the new BufferedImage:
final float FACTOR = 4f;
BufferedImage img = ImageIO.read(new File("graphic.png"));
int scaleX = (int) (img.getWidth() * FACTOR);
int scaleY = (int) (img.getHeight() * FACTOR);
Image image = img.getScaledInstance(scaleX, scaleY, Image.SCALE_SMOOTH);
BufferedImage buffered = new BufferedImage(scaleX, scaleY, TYPE);
buffered.getGraphics().drawImage(image, 0, 0 , null);
That should do the trick without casting.
I haven't tried specifically getting the VM settings, but there is a wealth of information in the JMX utilities specifically the MXBean utilities. This would be where I would start. Hopefully you find something there to help you.

Why haven't you tried httplib.HTTPSConnection? It doesn't do SSL validation but this isn't required to connect over https. Your code works fine with https connection:
>>> import httplib
>>> conn = httplib.HTTPSConnection("mail.google.com")
>>> conn.request("GET", "/")
>>> r1 = conn.getresponse()
>>> print r1.status, r1.reason
200 OK
For others same error may not always be due to column type mismatch, you can find out more information about a mysql foriegn key error by issuing command
SHOW ENGINE INNODB STATUS;
you may find a error near the top of the printed message something like

Edit: Oh ignore me, you're not using Visual Studio.
Have you added the reference to your project?
As in this sort of thing:
Here are two methods which the original author states was recommended by an IB engineer.
See the actual post for more details. I prefer method #2 as it seems simpler.
Method #1:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"BDCustomCell"];
if (cell == nil) {
// Create a temporary UIViewController to instantiate the custom cell.
UIViewController *temporaryController = [[UIViewController alloc] initWithNibName:@"BDCustomCell" bundle:nil];
// Grab a pointer to the custom cell.
cell = (BDCustomCell *)temporaryController.view;
[[cell retain] autorelease];
// Release the temporary UIViewController.
[temporaryController release];
}
return cell;
}
Method #2:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"BDCustomCell"];
if (cell == nil) {
// Load the top-level objects from the custom cell XIB.
NSArray *topLevelObjects = [[NSBundle mainBundle] loadNibNamed:@"BDCustomCell" owner:self options:nil];
// Grab a pointer to the first object (presumably the custom cell, as that's all the XIB should contain).
cell = [topLevelObjects objectAtIndex:0];
}
return cell;
}
Update (2014): Method #2 is still valid but there is no documentation for it anymore. It used to be in the official docs but is now removed in favor of storyboards.
I posted a working example on Github:
https://github.com/bentford/NibTableCellExample
edit for Swift 4.2
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
self.tblContacts.register(UINib(nibName: CellNames.ContactsCell, bundle: nil), forCellReuseIdentifier: MyIdentifier)
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: MyIdentifier, for: indexPath) as! ContactsCell
return cell
}
File f = new File("Test.txt");
if(!f.exists()){
f.createNewFile();
}else{
System.out.println("File already exists");
}
Pass this f
to your FileOutputStream
constructor.
Once you've created the frame the part of the code with your conditional isn't going to get entered. To put it another way, at the time you execute the test if (btn1Clicked == true)
, the button has not only not been clicked yet, it hasn't even been displayed to the user.
Lose the booleans and move the line with the btnConvertDocuments.setEnabled(false)
into your actionListener. Make the buttons instance variables, do not make them static variables. (Alternatively you could keep the buttons as local variables and assign each of them their own anonymous inner class listener.)
If you need to set a delay of less than a second, it is not necessary to set the .seconds parameter. I hope this is useful to someone.

I was able to stash just the untracked files by doing:
git stash save "tracked files I'm working on"
git stash save -u "untracked files I'm trying to stash"
git stash pop stash@{1}
The last one pops the stash of the tracked files, thus leaving only the untracked files stashed.
Update: Leaving this answer for historical reasons, but I don't recommend it. Please see the accepted answer above.
Tell Jackson to map using your custom [de]serialization classes:
@JsonSerialize(using = LocalDateTimeSerializer.class)
@JsonDeserialize(using = LocalDateTimeDeserializer.class)
private LocalDateTime ignoreUntil;
provide custom classes:
public class LocalDateTimeSerializer extends JsonSerializer<LocalDateTime> {
@Override
public void serialize(LocalDateTime arg0, JsonGenerator arg1, SerializerProvider arg2) throws IOException {
arg1.writeString(arg0.toString());
}
}
public class LocalDateTimeDeserializer extends JsonDeserializer<LocalDateTime> {
@Override
public LocalDateTime deserialize(JsonParser arg0, DeserializationContext arg1) throws IOException {
return LocalDateTime.parse(arg0.getText());
}
}
random fact: if i nest above classes and don't make them static, the error message is weird:
org.springframework.web.HttpMediaTypeNotSupportedException: Content type 'application/json;charset=UTF-8' not supported
Here is another solution: generate a bash script with all the variables and the contents of the template file, that script would look like this:
word=dog
i=1
cat << EOF
the number is ${i}
the word is ${word}
EOF
If we feed this script into bash it would produce the desired output:
the number is 1
the word is dog
Here is how to generate that script and feed that script into bash:
(
# Variables
echo word=dog
echo i=1
# add the template
echo "cat << EOF"
cat template.txt
echo EOF
) | bash
cat
command with HEREDOCIf you want to redirect this output into a file, replace the last line with:
) | bash > output.txt
In case none of the above works for you, and you happen to be overriding OnPreRenderComplete, make sure you call base.OnPreRenderComplete. My therapist is going to be happy to see me back
I generally tend towards #2, As a query argument (i.e. /api/resource?parameter=value ).
A third option is to actually post the parameter=value in the body.
This is because it works better for multi parameter resources and is more extendable for future use.
No matter which one you pick, make sure you only pick one, don't mix and match. That leads towards a confusing API.
Tuples are available since .NET4.0 and support generics:
Tuple<string, int> t = new Tuple<string, int>("Hello", 4);
In previous versions you can use System.Collections.Generic.KeyValuePair<K, V>
or a solution like the following:
public class Pair<T, U> {
public Pair() {
}
public Pair(T first, U second) {
this.First = first;
this.Second = second;
}
public T First { get; set; }
public U Second { get; set; }
};
And use it like this:
Pair<String, int> pair = new Pair<String, int>("test", 2);
Console.WriteLine(pair.First);
Console.WriteLine(pair.Second);
This outputs:
test
2
Or even this chained pairs:
Pair<Pair<String, int>, bool> pair = new Pair<Pair<String, int>, bool>();
pair.First = new Pair<String, int>();
pair.First.First = "test";
pair.First.Second = 12;
pair.Second = true;
Console.WriteLine(pair.First.First);
Console.WriteLine(pair.First.Second);
Console.WriteLine(pair.Second);
That outputs:
test
12
true
You may find that you have to link with the math libraries on whatever system you're using, something like:
gcc -o myprog myprog.c -L/path/to/libs -lm
^^^ - this bit here.
Including headers lets a compiler know about function declarations but it does not necessarily automatically link to the code required to perform that function.
Failing that, you'll need to show us your code, your compile command and the platform you're running on (operating system, compiler, etc).
The following code compiles and links fine:
#include <math.h>
int main (void) {
int max = sqrt (9);
return 0;
}
Just be aware that some compilation systems depend on the order in which libraries are given on the command line. By that, I mean they may process the libraries in sequence and only use them to satisfy unresolved symbols at that point in the sequence.
So, for example, given the commands:
gcc -o plugh plugh.o -lxyzzy
gcc -o plugh -lxyzzy plugh.o
and plugh.o
requires something from the xyzzy
library, the second may not work as you expect. At the point where you list the library, there are no unresolved symbols to satisfy.
And when the unresolved symbols from plugh.o
do appear, it's too late.
A callback is a function pointer that you pass in to another function. The function you are calling will 'callback' (execute) the other function when it has completed.
Check out this link.
Try this:
function btnClick() {
var x = document.getElementById("mytable").getElementsByTagName("td");
x[0].innerHTML = "i want to change my cell color";
x[0].style.backgroundColor = "yellow";
}
Set from JS, backgroundColor
is the equivalent of background-color
in your style-sheet.
Note also that the .cells
collection belongs to a table row, not to the table itself. To get all the cells from all rows you can instead use getElementsByTagName()
.
I know you're asking about using jQuery, but you can achieve the same effect in browsers that have JavaScript turned off using CSS:
#element {
width: 100px; /* width of image */
height: 200px; /* height of image */
background-image: url(/path/to/image.jpg);
}
#element:hover {
background-image: url(/path/to/other_image.jpg);
}

Even better, however, is to use sprites: simple-css-image-rollover
Apparently, there's a lot of "dead wood" in the "build" directories of a project.
Under linux/unix, a simple way to get a clean, private backup is to use the "tar" command along with the "--exclude=String" option.
For example, to create an archive of all my apps while excluding the build directories, I have a script that creates the following 2 commands :
cd $HOME/android/Studio
tar cvf MyBackup-2017-07-13.tar Projects --exclude=build
you can use if statement like below
select CONCAT(if(affiliate_name is null ,'',affiliate_name),'- ',if(model is null ,'',affiliate_name)) as model from devices
Use the dos2unix command in linux to convert the saved file. example :
dos2unix file_name
If you are using laravel

The practical reason why this doesn't work is not related to threads. The point is that node.left
is effectively translated into node.getLeft()
.
This property getter might be defined as:
val left get() = if (Math.random() < 0.5) null else leftPtr
Therefore two calls might not return the same result.
Solution for EF Core
public class User
{
public int Id { get; set; }
public string Name { get; set; }
public string Passport { get; set; }
}
public class ApplicationContext : DbContext
{
public DbSet<User> Users { get; set; }
public ApplicationContext()
{
Database.EnsureCreated();
}
protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
{
optionsBuilder.UseSqlServer(@"Server=(localdb)\mssqllocaldb;Database=efbasicsappdb;Trusted_Connection=True;");
}
protected override void OnModelCreating(ModelBuilder modelBuilder)
{
modelBuilder.Entity<User>().HasAlternateKey(u => u.Passport);
//or: modelBuilder.Entity<User>().HasAlternateKey(u => new { u.Passport, u.Name})
}
}
DB table will look like this:
CREATE TABLE [dbo].[Users] (
[Id] INT IDENTITY (1, 1) NOT NULL,
[Name] NVARCHAR (MAX) NULL,
[Passport] NVARCHAR (450) NOT NULL,
CONSTRAINT [PK_Users] PRIMARY KEY CLUSTERED ([Id] ASC),
CONSTRAINT [AK_Users_Passport] UNIQUE NONCLUSTERED ([Passport] ASC)
);
For python2, It's better to use e.message
to get the exception message, this will avoid possible UnicodeDecodeError
. But yes e.message
will be empty for some kind of exceptions like OSError
, in which case we can add a exc_info=True
to our logging function to not miss the error.
For python3, I think it's safe to use str(e)
.
For my use-case I was able to simply pipe to grep.
pg_dump -U user_name --data-only --column-inserts -t nyummy.cimory | grep "tokyo" > tokyo.sql

You don't have the namespace the Login class is in as a reference.
Add the following to the form that uses the Login
class:
using FootballLeagueSystem;
When you want to use a class in another namespace, you have to tell the compiler where to find it. In this case, Login
is inside the FootballLeagueSystem
namespace, or : FootballLeagueSystem.Login
is the fully qualified namespace.
As a commenter pointed out, you declare the Login class inside the FootballLeagueSystem
namespace, but you're using it in the FootballLeague
namespace.
instead of these custom error messages we can specify the type of the text field.
Ex: set type of the field in to type = 'email'
then plugin will identify the field and validate correctly.
Assuming the type is CV_8UC3 you would do this:
for(int i = 0; i < foo.rows; i++)
{
for(int j = 0; j < foo.cols; j++)
{
Vec3b bgrPixel = foo.at<Vec3b>(i, j);
// do something with BGR values...
}
}
Here is the documentation for Vec3b. Hope that helps! Also, don't forget OpenCV stores things internally as BGR not RGB.
EDIT :
For performance reasons, you may want to use direct access to the data buffer in order to process the pixel values:
Here is how you might go about this:
uint8_t* pixelPtr = (uint8_t*)foo.data;
int cn = foo.channels();
Scalar_<uint8_t> bgrPixel;
for(int i = 0; i < foo.rows; i++)
{
for(int j = 0; j < foo.cols; j++)
{
bgrPixel.val[0] = pixelPtr[i*foo.cols*cn + j*cn + 0]; // B
bgrPixel.val[1] = pixelPtr[i*foo.cols*cn + j*cn + 1]; // G
bgrPixel.val[2] = pixelPtr[i*foo.cols*cn + j*cn + 2]; // R
// do something with BGR values...
}
}
Or alternatively:
int cn = foo.channels();
Scalar_<uint8_t> bgrPixel;
for(int i = 0; i < foo.rows; i++)
{
uint8_t* rowPtr = foo.row(i);
for(int j = 0; j < foo.cols; j++)
{
bgrPixel.val[0] = rowPtr[j*cn + 0]; // B
bgrPixel.val[1] = rowPtr[j*cn + 1]; // G
bgrPixel.val[2] = rowPtr[j*cn + 2]; // R
// do something with BGR values...

Try this Bash syntax instead of trying to use an external program expr
:
count=$((FIRSTV-SECONDV))
BTW, the correct syntax of using expr
is:
count=$(expr $FIRSTV - $SECONDV)
But keep in mind using expr
is going to be slower than the internal Bash syntax I provided above.
I don't like the auto-commit that git revert
does, so this might be helpful for some.
If you just want the modified files not the auto-commit, you can use --no-commit
% git revert --no-commit <commit hash>
which is the same as the -n
% git revert -n <commit hash>

smtp_port=587
sendmail_from = [email protected]
sendmail_path = "C:\xampp\sendmail\sendmail.exe -t"
(use the above send mail path only and it will work)
Now Open C:\xampp\sendmail\sendmail.ini
. Replace all the existing code in sendmail.ini with following code
[sendmail]
smtp_server=smtp.gmail.com
smtp_port=587
error_logfile=error.log
debug_logfile=debug.log
[email protected]
auth_password=my-gmail-password
[email protected]
Now you have done!! create php file with mail function and send mail from localhost.
Update
First, make sure you PHP installation has SSL support (look for an "openssl" section in the output from phpinfo()
).
You can set the following settings in your PHP.ini:
ini_set("SMTP","ssl://smtp.gmail.com");
ini_set("smtp_port","465");
jsonIssues = [...jsonIssues,{ID:'3',Name:'name 3',Notes:'NOTES 3'}]
You can use querySelectorAll()
like this:
var test = document.querySelectorAll('input[value][type="checkbox"]:not([value=""])');
This translates to:
get all inputs with the attribute "value" and has the attribute "value" that is not blank.
In this demo, it disables the checkbox with a non-blank value.
If your databaseName
value is correct, then use this: DriverManger.getconnection("jdbc:sqlserver://ServerIp:1433;user=myuser;password=mypassword;databaseName=databaseName;")
Ok got this as:
var query = (from t in Transactions
group t by new {t.MaterialID, t.ProductID}
into grp
select new
{
grp.Key.MaterialID,
grp.Key.ProductID,
Quantity = grp.Sum(t => t.Quantity)
}).ToList();
open your browser,check whether Tomcat homepage is visible by below command.

Here is based on the answer from Mark Tolonen. The string included different languages of the word 'test' that's separated by '|', so you can see the difference.

It's worth to know that only both utf-8-sig
and utf-16
get back the original string after both encode
and decode
.
You can replace the values "null" from the original file & field/column.

I know that this question is a little old, but I thought that I would provide an alternative which, in my opinion, might be a little easier. If you're willing to add "temporary" columns to a data set, you can use Excel's Analysis ToolPak?Data Analysis?Regression. The secret to doing a quadratic or a cubic regression analysis is defining the Input X Range:.
If you're doing a simple linear regression, all you need are 2 columns, X & Y. If you're doing a quadratic, you'll need X_1, X_2, & Y where X_1 is the x variable and X_2 is x^2; likewise, if you're doing a cubic, you'll need X_1, X_2, X_3, & Y where X_1 is the x variable, X_2 is x^2 and X_3 is x^3. Notice how the Input X Range is from A1 to B22, spanning 2 columns.
The following image the output of the regression analysis. I've highlighted the common outputs, including the R-Squared values and all the coefficients.
There are many way you can do this. Those are given bellow:
Suppose your original number is given bellow: double number = 2354548.235;
Using NumberFormat
and Rounding mode
NumberFormat nf = DecimalFormat.getInstance(Locale.ENGLISH);
DecimalFormat decimalFormatter = (DecimalFormat) nf;
decimalFormatter.applyPattern("#,###,###.##");
decimalFormatter.setRoundingMode(RoundingMode.CEILING);
String fString = decimalFormatter.format(number);
System.out.println(fString);
Using String formatter
System.out.println(String.format("%1$,.2f", number));
In all cases the output will be: 2354548.24
Note:
During rounding you can add RoundingMode
in your formatter. Here are some Rounding mode given bellow:
decimalFormat.setRoundingMode(RoundingMode.CEILING);
decimalFormat.setRoundingMode(RoundingMode.FLOOR);
decimalFormat.setRoundingMode(RoundingMode.HALF_DOWN);
decimalFormat.setRoundingMode(RoundingMode.HALF_UP);
decimalFormat.setRoundingMode(RoundingMode.UP);
Here are the imports:
import java.math.BigDecimal;
import java.math.RoundingMode;
import java.text.DecimalFormat;
import java.text.NumberFormat;
import java.util.Locale;
You need to add z-index
to the divs, with a positive number for the top div and negative for the div below
Its blank because you are writing to file
. you should write to output
using php://output
instead and also send header information to indicate that it's csv.
Example
header('Content-Type: text/csv');
header('Content-Disposition: attachment; filename="sample.csv"');
$data = array(
'aaa,bbb,ccc,dddd',
'123,456,789',
'"aaa","bbb"'
);
$fp = fopen('php://output', 'wb');
foreach ( $data as $line ) {
$val = explode(",", $line);
fputcsv($fp, $val);
}
fclose($fp);
The best way is to simply reset the password by connecting with a domain/local admin (so you may need help from your system administrators), but this only works if SQL Server was set up to allow local admins (these are now left off the default admin group during setup).
If you can't use this or other existing methods to recover / reset the SA password, some of which are explained here:
Then you could always backup your important databases, uninstall SQL Server, and install a fresh instance.
You can also search for less scrupulous ways to do it (e.g. there are password crackers that I am not enthusiastic about sharing).
As an aside, the login properties for sa
would never say Windows Authentication. This is by design as this is a SQL Authentication account. This does not mean that Windows Authentication is disabled at the instance level (in fact it is not possible to do so), it just doesn't apply for a SQL auth account.
I wrote a tip on using PSExec to connect to an instance using the NT AUTHORITY\SYSTEM
account (which works < SQL Server 2012), and a follow-up that shows how to hack the SqlWriter service (which can work on more modern versions):
And some other resources:
$("#message > span").text("your text");
or
$("#message").find("span").text("your text");
or
$("span","#message").text("your text");
or
$("#message > a.close-notify").siblings('span').text("your text");
In my case, my Dockerfile contained an installation step, which produced the vendor
directory (the PHP equivalent of node_modules
). I then COPY
this directory over to the final application image. Therefore, I could not put vendor
in my .dockerignore
. My solution was simply to delete the directory before performing composer install
(the PHP equivalent of npm install
).
FROM composer AS composer
WORKDIR /app
COPY . .
RUN rm -rf vendor \
&& composer install
FROM richarvey/nginx-php-fpm
WORKDIR /var/www/html
COPY --from=composer /app .
This solution works and does not bloat the final image, but it is not ideal, because the vendor
directory on the host is copied into the Docker context during the build process, which adds time.
I had the same issue. Fixed it by adding a static route on my host to my VM via the VMnet8 adapter:
route ADD VM_addr MASK 255.255.255.255 VMnet8_addr
As previously mentioned, you need a bridged connection.
Apache supports name based and IP based virtual hosts. It looks like you are using both, which is probably not what you need.
I think you're actually trying to set up name-based virtual hosting, and for that you don't need to specify the IP address.
Try < VirtualHost *:80> to bind to all IP addresses, unless you really want ip based virtual hosting. This may be the case if the server has several IP addresses, and you want to serve different sites on different addresses. The most common setup is (I would guess) name based virtual hosts.
The best way to implement a RESTful search is to consider the search itself to be a resource. Then you can use the POST verb because you are creating a search. You do not have to literally create something in a database in order to use a POST.
For example:
Accept: application/json
Content-Type: application/json
POST http://example.com/people/searches
{
"terms": {
"ssn": "123456789"
},
"order": { ... },
...
}
You are creating a search from the user's standpoint. The implementation details of this are irrelevant. Some RESTful APIs may not even need persistence. That is an implementation detail.

I know there should be a proper way to solve it but just to save time
I uploaded my xlsx sheet to Google Sheets and then again downloaded it from Google Sheets it working now
If you don't have time to solve the problem, you can try this
The TextBox
has a property called ReadOnly
. If you set that property to true then the TextBox
will still be able to scroll but the user wont be able to change the value.
String [] args
is also how you declare an array of Strings in Java.
In this method signature, the array args
will be filled with values when the method is called (as the other examples here show). Since you're learning though, it's worth understanding that this args
array is just like if you created one yourself in a method, as in this:
public void foo() {
String [] args = new String[2];
args[0] = "hello";
args[1] = "every";
System.out.println("Output: " + args[0] + args[1]);
// etc... the usage of 'args' here and in the main method is identical
}
The command for your rescue is git clean
.

Thanks,Bruno for giving me heads up on Common Name and Subject Alternative Name. As we figured out certificate was generated with CN with DNS name of network and asked for regeneration of new certificate with Subject Alternative Name entry i.e. san=ip:10.0.0.1. which is the actual solution.
But, we managed to find out a workaround with which we can able to run on development phase. Just add a static block in the class from which we are making ssl connection.
static {
HttpsURLConnection.setDefaultHostnameVerifier(new HostnameVerifier()
{
public boolean verify(String hostname, SSLSession session)
{
// ip address of the service URL(like.23.28.244.244)
if (hostname.equals("23.28.244.244"))
return true;
return false;
}
});
}
If you happen to be using Java 8, there is a much slicker way of achieving the same result:
static {
HttpsURLConnection.setDefaultHostnameVerifier((hostname, session) -> hostname.equals("127.0.0.1"));
}
# This keeps all separators in result

You should be able to use the /quiet
or /qn
options with msiexec
to perform a silent install.
MSI packages export public properties, which you can set with the PROPERTY=value
syntax on the end of the msiexec
parameters.
For example, this command installs a package with no UI and no reboot, with a log and two properties:
msiexec /i c:\path\to\package.msi /quiet /qn /norestart /log c:\path\to\install.log PROPERTY1=value1 PROPERTY2=value2
You can read the options for msiexec
by just running it with no options from Start -> Run.
A single quote is used for character, while double quotes are used for strings.
printf("%c \n",'a');
printf("%s","Hello World");
a
Hello World
If you used these in vice versa case and used a single quote for string and double quotes for a character, this will be the result:
printf("%c \n","a");
printf("%s",'Hello World');
For the first line. You will get a garbage value or unexpected value or you may get an output like this:
?
While for the second statement, you will see nothing. One more thing, if you have more statements after this, they will also give you no result.
Note: PHP language gives you the flexibility to use single and double-quotes easily.
overflow-x: hidden;
would hide any thing on the x-axis that goes outside of the element, so there would be no need for the horizontal scrollbar and it get removed.
overflow-y: hidden;
would hide any thing on the y-axis that goes outside of the element, so there would be no need for the vertical scrollbar and it get removed.
overflow: hidden;
would remove both scrollbars
The project I'm working on, we do something like this. We use the errorlevel
keyword so it kind of looks like:
call myExe.exe
if errorlevel 1 (
goto build_fail
)
That seems to work for us. Note that you can put in multiple commands in the parens like an echo or whatever. Also note that build_fail is defined as:
:build_fail
echo ********** BUILD FAILURE **********
exit /b 1
The better answers to this only work for specific lengths of lists that are provided.
Here's a version that works for any lengths of input. It also makes the algorithm clear in terms of the mathematical concepts of combination and permutation.
from itertools import combinations, permutations
list1 = ['1', '2']
list2 = ['A', 'B', 'C']
num_elements = min(len(list1), len(list2))
list1_combs = list(combinations(list1, num_elements))
list2_perms = list(permutations(list2, num_elements))
result = [
tuple(zip(perm, comb))
for comb in list1_combs
for perm in list2_perms
]
for idx, ((l11, l12), (l21, l22)) in enumerate(result):
print(f'{idx}: {l11}{l12} {l21}{l22}')
This outputs:
0: A1 B2
1: A1 C2
2: B1 A2
3: B1 C2
4: C1 A2
5: C1 B2

There is a jinja2 extension you can use just need pip install (https://github.com/hackebrot/jinja2-time)
I prefer the way I just figured out... No JS... 100% HTML & CSS:
(Will center it perfectly in the middle, regardless of the content size.
HTML FILE
<html><head>
<link href="jane.css" rel="stylesheet" />
</head>
<body>
<table id="container">
<tr>
<td id="centerpiece">
123
</td></tr></table>
</body></html>
CSS FILE
#container{
border:0;
width:100%;
height:100%;
}
#centerpiece{
vertical-align:middle;
text-align:center;
}
for centering images / div's held within the td, you may wish to try margin:auto; and specify a div dimension instead. -Though, saying that... the 'text-align' property will align much more than just a simple text element.
If your AJAX script takes more than a couple milliseconds to run, eval() will always run ahead and evaluate the empty response element before AJAX populates it with the script you're trying to execute.
Rather than mucking around with timing and eval(), here is a pretty simple workaround that should work in most situations and is probably a bit more secure. Using eval() is generally frowned upon because the characters being evaluated as code can easily be manipulated client-side.
In this example, I want to attach a dynamic autocomplete list from the jquery-ui library to an AJAX element AFTER the element has been added to the page. Easy, right?

The parameter(s) to isset()
must be a variable reference and not an expression (in your case a concatenation); but you can group multiple conditions together like this:
if (isset($_POST['search_term'], $_POST['postcode'])) {
}
This will return true
only if all arguments to isset()
are set and do not contain null
.
Note that isset($var)
and isset($var) == true
have the same effect, so the latter is somewhat redundant.
Update
The second part of your expression uses empty()
like this:
empty ($_POST['search_term'] . $_POST['postcode']) == false
This is wrong for the same reasons as above. In fact, you don't need empty()
here, because by that time you would have already checked whether the variables are set, so you can shortcut the complete expression like so:
isset($_POST['search_term'], $_POST['postcode']) &&
$_POST['search_term'] &&
$_POST['postcode']
Or using an equivalent expression:
!empty($_POST['search_term']) && !empty($_POST['postcode'])
Final thoughts
You should consider using filter
functions to manage the inputs:
$data = filter_input_array(INPUT_POST, array(
'search_term' => array(
'filter' => FILTER_UNSAFE_RAW,
'flags' => FILTER_NULL_ON_FAILURE,
),
'postcode' => array(
'filter' => FILTER_UNSAFE_RAW,
'flags' => FILTER_NULL_ON_FAILURE,
),
));
if ($data === null || in_array(null, $data, true)) {
// some fields are missing or their values didn't pass the filter
die("You did something naughty");
}
// $data['search_term'] and $data['postcode'] contains the fields you want
Btw, you can customize your filters to check for various parts of the submitted values.

Perhaps you don't have to include the single quotes:
curl --request POST 'http://localhost/Service' --data "path=/xyz/pqr/test/&fileName=1.doc"
Update: Reading curl's manual, you could actually separate both fields with two --data:
curl --request POST 'http://localhost/Service' --data "path=/xyz/pqr/test/" --data "fileName=1.doc"
You could also try --data-binary:
curl --request POST 'http://localhost/Service' --data-binary "path=/xyz/pqr/test/" --data-binary "fileName=1.doc"
And --data-urlencode:
curl --request POST 'http://localhost/Service' --data-urlencode "path=/xyz/pqr/test/" --data-urlencode "fileName=1.doc"
Just thought i'd share this with anyone who needs more clarity on how to achieve this:
myCanvas is a Canvas control and Parent to all other controllers. This code works to neatly resize to any resolution from 1366 x 768 upward. Tested up to 4k resolution 4096 x 2160

I have used mpdf in my project. In Codeigniter-3, putted mpdf files under application/third_party and then used in this way:
/**
* This function is used to display data in PDF file.
* function is using mpdf api to generate pdf.
* @param number $id : This is unique id of table.
*/
function generatePDF($id){
require APPPATH . '/third_party/mpdf/vendor/autoload.php';
//$mpdf=new mPDF();
$mpdf = new mPDF('utf-8', 'Letter', 0, '', 0, 0, 7, 0, 0, 0);
$checkRecords = $this->user_model->getCheckInfo($id);
foreach ($checkRecords as $key => $value) {
$data['info'] = $value;
$filename = $this->load->view(CHEQUE_VIEWS.'index',$data,TRUE);
$mpdf->WriteHTML($filename);
}
$mpdf->Output(); //output pdf document.
//$content = $mpdf->Output('', 'S'); //get pdf document content's as variable.
}
check your value which you want to store in integer column. I think this is greater then range of integer. if you want to store value greater then integer range. you should use bigint datatype
What's the difference between an RDD's map and mapPartitions method?
The method map converts each element of the source RDD into a single element of the result RDD by applying a function. mapPartitions converts each partition of the source RDD into multiple elements of the result (possibly none).
And does flatMap behave like map or like mapPartitions?
Neither, flatMap works on a single element (as map
) and produces multiple elements of the result (as mapPartitions
).

You may set the timeout either globally for entire server:
var server = app.listen();
server.setTimeout(500000);
or just for specific route:
app.post('/xxx', function (req, res) {
req.setTimeout(500000);
});
I needed a Month/Year picker for two fields (From & To) and when one was chosen the Max/Min was set on the other one...a la picking airline ticket dates. I was having issues setting the max and min...the dates of the other field would get erased. Thanks to several of the above posts...I finally figured it out. You have to set options and dates in a very specific order.
See this fiddle for the full solution: Month/Year Picker @ JSFiddle
Code:
var searchMinDate = "-2y";
var searchMaxDate = "-1m";
if ((new Date()).getDate() <= 5) {
searchMaxDate = "-2m";
}
$("#txtFrom").datepicker({
dateFormat: "M yy",
changeMonth: true,
changeYear: true,
showButtonPanel: true,
showAnim: "",
minDate: searchMinDate,
maxDate: searchMaxDate,
showButtonPanel: true,
beforeShow: function (input, inst) {
if ((datestr = $("#txtFrom").val()).length > 0) {
var year = datestr.substring(datestr.length - 4, datestr.length);
var month = jQuery.inArray(datestr.substring(0, datestr.length - 5), "#txtFrom").datepicker('option', 'monthNamesShort'));
$("#txtFrom").datepicker('option', 'defaultDate', new Date(year, month, 1));
$("#txtFrom").datepicker('setDate', new Date(year, month, 1));
}
},
onClose: function (input, inst) {
var month = $("#ui-datepicker-div .ui-datepicker-month :selected").val();
var year = $("#ui-datepicker-div .ui-datepicker-year :selected").val();
$("#txtFrom").datepicker('option', 'defaultDate', new Date(year, month, 1));
$("#txtFrom").datepicker('setDate', new Date(year, month, 1));
var to = $("#txtTo").val();
$("#txtTo").datepicker('option', 'minDate', new Date(year, month, 1));
if (to.length > 0) {
var toyear = to.substring(to.length - 4, to.length);
var tomonth = jQuery.inArray(to.substring(0, to.length - 5), $("#txtTo").datepicker('option', 'monthNamesShort'));
$("#txtTo").datepicker('option', 'defaultDate', new Date(toyear, tomonth, 1));
$("#txtTo").datepicker('setDate', new Date(toyear, tomonth, 1));
}
}
});
$("#txtTo").datepicker({
dateFormat: "M yy",
changeMonth: true,
changeYear: true,
showButtonPanel: true,
showAnim: "",
minDate: searchMinDate,
maxDate: searchMaxDate,
showButtonPanel: true,
beforeShow: function (input, inst) {
if ((datestr = $("#txtTo").val()).length > 0) {
var year = datestr.substring(datestr.length - 4, datestr.length);
var month = jQuery.inArray(datestr.substring(0, datestr.length - 5), $("#txtTo").datepicker('option', 'monthNamesShort'));
$("#txtTo").datepicker('option', 'defaultDate', new Date(year, month, 1));
$("#txtTo").datepicker('setDate', new Date(year, month, 1));
}
},
onClose: function (input, inst) {
var month = $("#ui-datepicker-div .ui-datepicker-month :selected").val();
var year = $("#ui-datepicker-div .ui-datepicker-year :selected").val();
$("#txtTo").datepicker('option', 'defaultDate', new Date(year, month, 1));
$("#txtTo").datepicker('setDate', new Date(year, month, 1));
var from = $("#txtFrom").val();
$("#txtFrom").datepicker('option', 'maxDate', new Date(year, month, 1));
if (from.length > 0) {
var fryear = from.substring(from.length - 4, from.length);
var frmonth = jQuery.inArray(from.substring(0, from.length - 5), $("#txtFrom").datepicker('option', 'monthNamesShort'));
$("#txtFrom").datepicker('option', 'defaultDate', new Date(fryear, frmonth, 1));
$("#txtFrom").datepicker('setDate', new Date(fryear, frmonth, 1));
}
}
});
Also add this to a style block as mentioned above:
.ui-datepicker-calendar { display: none !important; }
I discovered git-annex recently which I find awesome. It was designed for managing large files efficiently. I use it for my photo/music (etc.) collections. The development of git-annex is very active. The content of the files can be removed from the Git repository, only the tree hierarchy is tracked by Git (through symlinks). However, to get the content of the file, a second step is necessary after pulling/pushing, e.g.:
$ git annex add mybigfile
$ git commit -m'add mybigfile'
$ git push myremote
$ git annex copy --to myremote mybigfile ## This command copies the actual content to myremote
$ git annex drop mybigfile ## Remove content from local repo
...
$ git annex get mybigfile ## Retrieve the content
## or to specify the remote from which to get:
$ git annex copy --from myremote mybigfile
There are many commands available, and there is a great documentation on the website. A package is available on Debian.
let vc = DetailUserViewController()
vc.userdetails = userViewModels[indexPath.row]
self.navigationController?.pushViewController(vc, animated: true)
I think your problem is that you send the broadcast before the other activity start ! so the other activity will not receive anything .
Just incase anyone else stumbles across this, I use the fs-extra library in node and write javascript objects to a file like this:
const fse = require('fs-extra');
fse.outputJsonSync('path/to/output/file.json', objectToWriteToFile);
In about:config
add content.cors.disable
(empty string).
You may try with below query :
INSERT INTO errortable (dateupdated,table1id)
VALUES (to_date(to_char(sysdate,'dd/mon/yyyy hh24:mi:ss'), 'dd/mm/yyyy hh24:mi:ss' ),1083 );
To view the result of it:
SELECT to_char(hire_dateupdated, 'dd/mm/yyyy hh24:mi:ss')
FROM errortable
WHERE table1id = 1083;
If you'd like to do this in ggplot
, an API change was made to geom_histogram()
that leads to an error: https://github.com/hadley/ggplot2/issues/1465
To get around this, use geom_bar()
:
animals <- c("cat", "dog", "dog", "dog", "dog", "dog", "dog", "dog", "cat", "cat", "bird")
library(ggplot2)
# counts
ggplot(data.frame(animals), aes(x=animals)) +
geom_bar()
Sample:
Label label = new Label();
label.HorizontalContentAlignment = HorizontalAlignment.Center;
you can write for all user list :
sudo crontab -u userName -l
,
You can also go to
cd /etc/cron.daily/
ls -l
cat filename
this file will list the schedules
cd /etc/cron.d/
ls -l
cat filename
Matheus de Oliveira created handy functions for JSON CRUD operations in postgresql. They can be imported using the \i directive. Notice the jsonb fork of the functions if jsonb if your data type.

You can directly use (String)session.getAttribute("username"); inside scriptlet tag ie <% %>.
Bootstrap3
CSS (gutter only, without margins around):
.row.row-gutter {
margin-bottom: -15px;
overflow: hidden;
}
.row.row-gutter > *[class^="col"] {
margin-bottom: 15px;
}
CSS (equal margins around, 15px/2):
.row.row-margins {
padding-top: 7px; /* or margin-top: 7px; */
padding-bottom: 7px; /* or margin-bottom: 7px; */
}
.row.row-margins > *[class^="col"] {
margin-top: 8px;
margin-bottom: 8px;
}
Usage:
<div class="row row-gutter">
<div class="col col-sm-9">first</div>
<div class="col col-sm-3">second</div>
<div class="col col-sm-12">third</div>
</div>
(with SASS or LESS 15px could be a variable from bootstrap)
Based on @brettdj's answer using a VBScript regex ojbect with two modifications:

I had a similar issue reading the serial output from a digital scale. I was reading [3:12] out of a 18 characters long output string.
In my case sometimes there is a null character "\x00" (NUL) which magically appears in the scale's reply string and is not printed.
I was getting the error:
> ' 0.00'
> 3 0 fast loop, delta = 10.0 weight = 0.0
> ' 0.00'
> 1 800 fast loop, delta = 10.0 weight = 0.0
> ' 0.00'
> 6 0 fast loop, delta = 10.0 weight = 0.0
> ' 0\x00.0'
> Traceback (most recent call last):
> File "measure_weight_speed.py", line 172, in start
> valueScale = float(answer_string)
> ValueError: invalid literal for float(): 0
After some research I wrote few lines of code that work in my case.
replyScale = scale_port.read(18)
answer = replyScale[3:12]
answer_decode = answer.replace("\x00", "")
answer_strip = str(answer_decode.strip())
print(repr(answer_strip))
valueScale = float(answer_strip)

Try to remove multidex from default config and check the build error log. If that log is some relatable with INotification class. Use this in android{}
configurations {
all*.exclude group: 'com.android.support', module: 'support-v4'

This helps me.
The proposed answers are great. Just would like to suggest an improvement to handle the case of null list using Optional.ofNullable
, new feature in Java 8:
List<String> carsFiltered = Optional.ofNullable(cars)
.orElseGet(Collections::emptyList)
.stream()
.filter(Objects::nonNull)
.collect(Collectors.toList());
So, the full answer will be:
List<String> carsFiltered = Optional.ofNullable(cars)
.orElseGet(Collections::emptyList)
.stream()
.filter(Objects::nonNull) //filtering car object that are null
.map(Car::getName) //now it's a stream of Strings
.filter(Objects::nonNull) //filtering null in Strings
.filter(name -> name.startsWith("M"))
.collect(Collectors.toList()); //back to List of Strings
If you are using bash shell you can use this:
time bash -c $'
FILE=/dev/shm/test.db
sqlite3 $FILE "create table if not exists tab(id int);"
sqlite3 $FILE "insert into tab values (1),(2)"
for i in 1 2 3 4; do sqlite3 $FILE "INSERT INTO tab (id) select (a.id+b.id+c.id)*abs(random()%1e7) from tab a, tab b, tab c limit 5e5"; done;
sqlite3 $FILE "select count(*) from tab;"'
Or if you are in sqlite CLI, then you need to do this:
create table if not exists tab(id int);"
insert into tab values (1),(2);
INSERT INTO tab (id) select (a.id+b.id+c.id)*abs(random()%1e7) from tab a, tab b, tab c limit 5e5;
INSERT INTO tab (id) select (a.id+b.id+c.id)*abs(random()%1e7) from tab a, tab b, tab c limit 5e5;
INSERT INTO tab (id) select (a.id+b.id+c.id)*abs(random()%1e7) from tab a, tab b, tab c limit 5e5;
INSERT INTO tab (id) select (a.id+b.id+c.id)*abs(random()%1e7) from tab a, tab b, tab c limit 5e5;
select count(*) from tab;
How does it work?
It makes use of that if table tab
:
id int
------
1
2
then select a.id, b.id from tab a, tab b
returns
a.id int | b.id int
------------------
1 | 1
2 | 1
1 | 2
2 | 2
and so on. After first execution we insert 2 rows, then 2^3=8. (three because we have tab a, tab b, tab c
)
After second execution we insert additional (2+8)^3=1000
rows
Aftern thrid we insert about max(1000^3, 5e5)=500000
rows and so on...
This is the fastest known for me method of populating SQLite database.
If you want to trim all spaces, only in lines that have a comma, and use awk
, then the following will work for you:
awk -F, '/,/{gsub(/ /, "", $0); print} ' input.txt
If you only want to remove spaces in the second column, change the expression to
awk -F, '/,/{gsub(/ /, "", $2); print$1","$2} ' input.txt
Note that gsub
substitutes the character in //
with the second expression, in the variable that is the third parameter - and does so in-place
- in other words, when it's done, the $0
(or $2
) has been modified.
Full explanation:
-F, use comma as field separator
(so the thing before the first comma is $1, etc)
/,/ operate only on lines with a comma
(this means empty lines are skipped)
gsub(a,b,c) match the regular expression a, replace it with b,
and do all this with the contents of c
print$1","$2 print the contents of field 1, a comma, then field 2
input.txt use input.txt as the source of lines to process
EDIT I want to point out that @BMW's solution is better, as it actually trims only leading and trailing spaces with two successive gsub
commands. Whilst giving credit I will give an explanation of how it works.
gsub(/^[ \t]+/,"",$2); - starting at the beginning (^) replace all (+ = zero or more, greedy)
consecutive tabs and spaces with an empty string
gsub(/[ \t]+$/,"",$2)} - do the same, but now for all space up to the end of string ($)
1 - ="true". Shorthand for "use default action", which is print $0
- that is, print the entire (modified) line
For database :
USE db_name; SELECT @@character_set_database;
There is no problem with whitespaces in the path since you're not using the "shell" to open the file. Here is a session from the windows console to prove the point. You're doing something else wrong

Assuming you have a list of object of type Person, using Lambda expression, you can sort the last names of users for instance by doing the following:
import java.util.Arrays;
import java.util.Collections;
import java.util.Comparator;
import java.util.List;
class Person {
private String firstName;
private String lastName;
public Person(String firstName, String lastName){
this.firstName = firstName;
this.lastName = lastName;
}
public String getLastName(){
return this.lastName;
}
public String getFirstName(){
return this.firstName;
}
@Override
public String toString(){
return "Person: "+ this.getFirstName() + " " + this.getLastName();
}
}
class TestSort {
public static void main(String[] args){
List<Person> people = Arrays.asList(
new Person("John", "Max"),
new Person("Coolio", "Doe"),
new Person("Judith", "Dan")
);
//Making use of lambda expression to sort the collection
people.sort((p1, p2)->p1.getLastName().compareTo(p2.getLastName()));
//Print sorted
printPeople(people);
}
public static void printPeople(List<Person> people){
for(Person p : people){
System.out.println(p);
}
}
}
random.uniform(a, b)
appears to be what your looking for. From the docs:
Return a random floating point number N such that a <= N <= b for a <= b and b <= N <= a for b < a.

The size of the numerical types is not defined in the C++ standard, although the minimum sizes are. The way to tell what size they are on your platform is to use numeric limits
For example, the maximum value for a int can be found by:
std::numeric_limits<int>::max();
Computers don't work in base 10, which means that the maximum value will be in the form of 2n-1 because of how the numbers of represent in memory. Take for example eight bits (1 byte)
0100 1000
The right most bit (number) when set to 1 represents 20, the next bit 21, then 22 and so on until we get to the left most bit which if the number is unsigned represents 27.
So the number represents 26 + 23 = 64 + 8 = 72, because the 4th bit from the right and the 7th bit right the left are set.
If we set all values to 1:
11111111
The number is now (assuming unsigned)
128 + 64 + 32 + 16 + 8 + 4 + 2 + 1 = 255 = 28 - 1
And as we can see, that is the largest possible value that can be represented with 8 bits.
On my machine and int and a long are the same, each able to hold between -231 to 231 - 1. In my experience the most common size on modern 32 bit desktop machine.
In case you only want to purge the queues which are not empty (a lot faster):
rabbitmqctl list_queues | awk '$2!=0 { print $1 }' | sed 's/Listing//' | xargs -L1 rabbitmqctl purge_queue
For me, it takes 2-3 seconds to purge a queue (both empty and non-empty ones), so iterating through 50 queues is such a pain while I just need to purge 10 of them (40/50 are empty).
You could use String.rstrip
.
result = string.rstrip('/')
In addition to VAV's answer, The first one was most useful in my environment
select * from USER_ROLE_PRIVS where USERNAME='SAMPLE';
select * from USER_TAB_PRIVS where Grantee = 'SAMPLE';
select * from USER_SYS_PRIVS where USERNAME = 'SAMPLE';
For tables you must loop that:
for tbl in `psql -qAt -c "select tablename from pg_tables where schemaname = 'public';" YOUR_DB` ; do psql -U postgres -c "alter table \"$tbl\" owner to NEW_USER" YOUR_DB ; done
Actually, you can get PowerShell to run using .NET 4 without affecting other .NET applications. I needed to do so to use the new HttpWebRequest "Host" property, however changing the "OnlyUseLatestCLR" broke Fiddler as that could not be used under .NET 4.
The developers of PowerShell obviously foresaw this happening, and they added a registry key to specify what version of the Framework it should use. One slight issue is that you need to take ownership of the registry key before changing it, as even administrators do not have access.
Change the value of that key to the required version. Keep in mind though that some snapins may no longer load unless they are .NET 4 compatible (WASP is the only one I have had trouble with, but I don't really use it anyway). VMWare, SQL Server 2008, PSCX, Active Directory (Microsoft and Quest Software) and SCOM all work fine.
nput from a terminal never really "ends" (unless the device is disconnected), but it is useful to enter more than one "file" into a terminal, so a key sequence is reserved to indicate end of input. In UNIX the translation of the keystroke to EOF is performed by the terminal driver, so a program does not need to distinguish terminals from other input files. By default, the driver converts a Control-D character at the start of a line into an end-of-file indicator. To insert an actual Control-D (ASCII 04) character into the input stream, the user precedes it with a "quote" command character (usually Control-V). AmigaDOS is similar but uses Control-\ instead of Control-D.
In Microsoft's DOS and Windows (and in CP/M and many DEC operating systems), reading from the terminal will never produce an EOF. Instead, programs recognize that the source is a terminal (or other "character device") and interpret a given reserved character or sequence as an end-of-file indicator; most commonly this is an ASCII Control-Z, code 26. Some MS-DOS programs, including parts of the Microsoft MS-DOS shell (COMMAND.COM) and operating-system utility programs (such as EDLIN), treat a Control-Z in a text file as marking the end of meaningful data, and/or append a Control-Z to the end when writing a text file. This was done for two reasons:
Backward compatibility with CP/M. The CP/M file system only recorded the lengths of files in multiples of 128-byte "records", so by convention a Control-Z character was used to mark the end of meaningful data if it ended in the middle of a record. The MS-DOS filesystem has always recorded the exact byte-length of files, so this was never necessary on MS-DOS.
It allows programs to use the same code to read input from both a terminal and a text file.
Do it like this:
$foo = new stdClass();
$foo->{"bar"} = '1234';
now try:
echo $foo->bar; // should display 1234
The DATE_ADD() function will do the trick. (You can also use the ADDTIME() function if you're running at least v4.1.1.)
For your query, this would be:
SELECT *
FROM courses
WHERE DATE_ADD(now(), INTERVAL 2 HOUR) > start_time
Or,
SELECT *
FROM courses
WHERE ADDTIME(now(), '02:00:00') > start_time
$(document).ready(function() {
$("input:text").focus(function() { $(this).select(); } );
});
The only alternative to using a loop is to use recursion.
You can define a method like
public static int sum(List<Integer> ints) {
return ints.isEmpty() ? 0 : ints.get(0) + ints.subList(1, ints.length());
}
This is very inefficient compared to using a plain loop and can blow up if you have many elements in the list.
An alternative which avoid a stack overflow is to use.
public static int sum(List<Integer> ints) {
int len = ints.size();
if (len == 0) return 0;
if (len == 1) return ints.get(0);
return sum(ints.subList(0, len/2)) + sum(ints.subList(len/2, len));
}
This is just as inefficient, but will avoid a stack overflow.
The shortest way to write the same thing is
int sum = 0, a[] = {2, 4, 6, 8};
for(int i: a) {
sum += i;
}
System.out.println("sum(a) = " + sum);
prints
sum(a) = 20
For some information I've get error after changing password:
Access denied for user 'root'@'localhost' (using password: NO)
Access denied for user 'root'@'localhost' (using password: YES)
In both cases there was error.
But the thing is after that I've tried it with
mysql -uroot -ppassword
instead of
mysql -u root -p password
-> with spaces between -uroot and -ppassword so maybe if someone get trouble can try this way.
Try to use pseudo classes like :first-child & :last-child to remove extra padding from first & last child.
Inspect the generated code of slick slider & try to remove padding on that.
Hope, it'll help!!!
Worth to mention some straightforward definitions:
Classes/Methods
You can declare some or all of a class methods as
final
, in order to indicate that the method cannot be overridden by subclasses.
Variables
Once a
final
variable has been initialized, it always contains the same value.
final
basically avoid overwrite/superscribe by anything (subclasses, variable "reassign"), depending on the case.
Take Inputs from User and Insertion Sort. Here is how it works:
package com.learning.constructor;
import java.util.Scanner;
public class InsertionSortArray {
public static void main(String[] args) {
Scanner s=new Scanner(System.in);
System.out.println("enter number of elements");
int n=s.nextInt();
int arr[]=new int[n];
System.out.println("enter elements");
for(int i=0;i<n;i++){//for reading array
arr[i]=s.nextInt();
}
System.out.print("Your Array Is: ");
//for(int i: arr){ //for printing array
for (int i = 0; i < arr.length; i++){
System.out.print(arr[i] + ",");
}
System.out.println("\n");
int[] input = arr;
insertionSort(input);
}
private static void printNumbers(int[] input) {
for (int i = 0; i < input.length; i++) {
System.out.print(input[i] + ", ");
}
System.out.println("\n");
}
public static void insertionSort(int array[]) {
int n = array.length;
for (int j = 1; j < n; j++) {
int key = array[j];
int i = j-1;
while ( (i > -1) && ( array [i] > key ) ) {
array [i+1] = array [i];
i--;
}
array[i+1] = key;
printNumbers(array);
}
}
}
A third option, for a pipelined one-liner is to nest the -replaces:
PS> ("ABC" -replace "B","C") -replace "C","D"
ADD
And:
PS> ("ABC" -replace "C","D") -replace "B","C"
ACD
This preserves execution order, is easy to read, and fits neatly into a pipeline. I prefer to use parentheses for explicit control, self-documentation, etc. It works without them, but how far do you trust that?
-Replace is a Comparison Operator, which accepts an object and returns a presumably modified object. This is why you can stack or nest them as shown above.
Please see:
help about_operators
You can create SQL CLR scalar function in order to be able to use regular expressions like replace patterns.
Here you can find example of how to create such function.
Having such function will solve the issue with just the following lines:
SELECT [dbo].[fn_Utils_RegexReplace] ('AB ABCDE # 123', '[^0-9]', '');
SELECT [dbo].[fn_Utils_RegexReplace] ('ABCDE# 123', '[^0-9]', '');
SELECT [dbo].[fn_Utils_RegexReplace] ('AB: ABC# 123', '[^0-9]', '');
More important, you will be able to solve more complex issues as the regular expressions will bring a whole new world of options directly in your T-SQL statements.
find . -type f -empty -exec rm -f {} \;
Mutable and immutable are English words meaning "can change" and "cannot change" respectively. The meaning of the words is the same in the IT context; i.e.
The meanings of these words are the same in C# / .NET as in other programming languages / environments, though (obviously) the names of the types may differ, as may other details.
For the record:
String
is the standard C# / .Net immutable string typeStringBuilder
is the standard C# / .Net mutable string typeTo "effect a change" on a string represented as a C# String
, you actually create a new String
object. The original String
is not changed ... because it is unchangeable.
In most cases it is better to use String
because it is easier reason about them; e.g. you don't need to consider the possibility that some other thread might "change my string".
However, when you need to construct or modify a string using a sequence of operations, it may be more efficient to use a StringBuilder
. An example is when you are concatenating many string fragments to form a large string:
String
concatenations, you copy O(N^2)
characters, where N
is the number of component strings.StringBuilder
you only copy O(N)
characters.And finally, for those people who assert that a StringBuilder
is not a string because it is not immutable, the Microsoft documentation describes StringBuilder
thus:
"Represents a mutable string of characters. This class cannot be inherited."
The following link seems to work fine -
<a href="whatsapp://send?text=Hello World!&phone=+9198********1">Ping me on WhatsApp</a>
It opens the contact in WhatsApp app, along with the message 'Hello World!' prepopulated in the input text box.
(Tested this with google chrome on an android phone.)
Regular expressions might be the best tool here. If you are not famililar with them, I recommend you install Expresso - a great little regex tool.
Something like:
Regex regex = new Regex("\\((?<TextInsideBrackets>\\w+)\\)");
string incomingValue = "Username (sales)";
string insideBrackets = null;
Match match = regex.Match(incomingValue);
if(match.Success)
{
insideBrackets = match.Groups["TextInsideBrackets"].Value;
}
uname -a works with my fc11
There are several ways to do plots in R; lattice
is one of them, and always a reasonable solution, +1 to @agstudy. If you want to do this in base graphics, you could try the following:
Reasonstats <- read.table(text="Category Reason Species
Decline Genuine 24
Improved Genuine 16
Improved Misclassified 85
Decline Misclassified 41
Decline Taxonomic 2
Improved Taxonomic 7
Decline Unclear 41
Improved Unclear 117", header=T)
ReasonstatsDec <- Reasonstats[which(Reasonstats$Category=="Decline"),]
ReasonstatsImp <- Reasonstats[which(Reasonstats$Category=="Improved"),]
Reasonstats3 <- cbind(ReasonstatsImp[,3], ReasonstatsDec[,3])
colnames(Reasonstats3) <- c("Improved", "Decline")
rownames(Reasonstats3) <- ReasonstatsImp$Reason
windows()
barplot(t(Reasonstats3), beside=TRUE, ylab="number of species",
cex.names=0.8, las=2, ylim=c(0,120), col=c("darkblue","red"))
box(bty="l")
Here's what I did: I created a matrix with two columns (because your data were in columns) where the columns were the species counts for Decline
and for Improved
. Then I made those categories the column names. I also made the Reason
s the row names. The barplot()
function can operate over this matrix, but wants the data in rows rather than columns, so I fed it a transposed version of the matrix. Lastly, I deleted some of your arguments to your barplot()
function call that were no longer needed. In other words, the problem was that your data weren't set up the way barplot()
wants for your intended output.
I resolved this problem by deleting the registry key under
hkey_current_user\software\Microsoft\VSCommon\12.0\clientservices\tokenstorage\visualstudio\ideuser
Even if you want to accept numbers for the input, I would recommend using the text
type.
<input type="text" name"some-number" />
Client-side run some jQuery validations to verify it's a number.
Then in your server side code, run some validation to verify it is in fact a numerical value.
This will work.
