It was really frustrating as it was still happening in the workbench version 6.3.10 (for mac) available in the mysql official site (here). I got it resolved by first collapsing the bottom panel (check the top right in the attached image (termed as collapse button)) and then pulling up the empty region from the bottom. Now if I again click on collapse button this time result grid is visible along with the action grid.
See here for starting the service and here for how to make it permanent. In short to test it, open a "DOS" terminal with administrator privileges and write:
shell> "C:\Program Files\MySQL\[YOUR MYSQL VERSION PATH]\bin\mysqld"
NOTE: The previous answers here aren't particularly useful if the BLOB is an arbitrary sequence of bytes; e.g. BINARY(16) to store 128-bit GUID or md5 checksum.
In that case, there currently is no editor preference -- though I have submitted a feature request now -- see that request for more detailed explanation.
[Until/unless that feature request is implemented], the solution is HEX
function in a query: SELECT HEX(mybinarycolumn) FROM mytable
.
An alternative is to use phpMyAdmin instead of MySQL Workbench - there hex is shown by default.
For older versions:
Open MySQL Workbench > Home > Manage Import / Export (Right bottom) / Select Required DB > Advance Exports Options Tab >Complete Insert [Checked] > Start Export.
For 6.1 and beyond, thanks to ryandlf:
Click the management tab (beside schemas) and choose Data Export.
Hope it helps.
---Edited answer---
Regarding selection of the schema. MySQL Workbench (5.2.47 CE Rev1039) does not yet support exporting to the user defined schema. It will create only the schema for which you exported the .sql... In 5.2.47 we see "New" target schema. But it does not work. I use MySQL Administrator (the old pre-Oracle MySQL Admin beauty) for my work for backup/restore. You can still download it from Googled trustable sources (search MySQL Administrator 1.2.17).
This exact question is answered on mySql workbench-faq:
Hover over an acronym to view a description, and see the Section 8.1.11.2, “The Columns Tab” and MySQL CREATE TABLE documentation for additional details.
That means hover over an acronym in the mySql Workbench table editor.
I had this problem and I just realized that if in the server you see the user in the menu SERVER -> USERS AND PRIVILEGES and find the user who has % as HOSTNAME, you can use it instead the root user.
That's all
From the now unavailable internet archive:
Go to Edit -> Preferences -> SQL Editor and set to a higher value this parameter: DBMS connection read time out (in seconds). For instance: 86400.
Close and reopen MySQL Workbench. Kill your previously query that probably is running and run the query again.
I faced this problem while installing Testlink on Ubuntu server, I followed these steps
mysql -u root
use mysql;
update user set password=PASSWORD("root") where User='root';
flush privileges;
quit
Now stop the instance and start again i.e
sudo /etc/init.d/mysql stop
sudo /etc/init.d/mysql start
Try opening services.msc
from the start menu search box and try manually starting the MySQL service or directly write services.msc
in Run
box
Maybe you are not allowed to start the service "MySQL 55". Set the login information of Service "MySQL 55" as local!
To see the list of aviable services in Windows 7:
services.msc
and press return.MySQL55
If you're on the Model Overview page you get a tab with the schema. If you rightclick on that tab you get an option to "edit schema". From there you can rename the schema by adding a new name, then click outside the field. This goes for MySQL Workbench 5.2.30 CE
Edit: On the model overview it's under Physical Schemata
Screenshot:
MySQL is different from most DBMSs use of +
or ||
for concatenation. It uses the CONCAT
function:
SELECT CONCAT(first_name, " ", last_name) AS Name FROM test.student
As @eggyal pointed out in comments, you can enable string concatenation with the ||
operator in MySQL by setting the PIPES_AS_CONCAT
SQL mode.
You can also use SET instead of DECLARE
SET @myvar := (SELECT somevalue INTO myvar FROM mytable WHERE uid=1);
SELECT myvar;
U can use MySQL Proxy and its scripting system to view SQL queries in realtime in the terminal.
just type SET SQL_SAFE_UPDATES = 0; before the delete or update and set to 1 again SET SQL_SAFE_UPDATES = 1
With mysql 5.7, date value like 0000-00-00 00:00:00 is not allowed.
If you want to allow it, you have to update your my.cnf like:
sudo nano /etc/mysql/my.cnf
find
[mysqld]
Add after:
sql_mode="NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION"
Restart mysql service:
sudo service mysql restart
Done!
mysqladmin
is not a SQL statement. It's a little helper utility program you'll find on your MySQL server... and "flush-hosts" is one of the things it can do. ("status" and "shutdown" are a couple of other things that come to mind).
You type that command from a shell prompt.
Alternately, from your query browser (such as phpMyAdmin), the SQL statement you're looking for is simply this:
FLUSH HOSTS;
>
Data ExportYou can select the rows from the table you want to export in the MySQL Workbench SQL Editor. You will find an Export button in the resultset that will allow you to export the records to a CSV file, as shown in the following image:
Please also keep in mind that by default MySQL Workbench limits the size of the resultset to 1000 records. You can easily change that in the Preferences dialog:
Hope this helps.
If you set a default schema for your DB Connection then Select will run in readonly mode until you set explicitly your schema
USE mydb;
SELECT * FROM mytable
this will also run in edit mode:
SELECT * FROM mydb.mytable
(MySql 5.2.42 / MacOsX)
I hope this helps.
Use MySQL Workbench. create SQL dump file of your database
Follow below steps:
It's not really a programming question, but it's a quick one so let me answer that. MySQL Workbench's themes are a collection of colors for certain main parts of the application. It is planned to allow customizing them in a later version. In order to get a dark theme as one of the templates please file a feature request at http://bugs.mysql.com. But keep in mind, not every UI element is colored according to the Workbench theme, e.g. text boxes still stay white as they use the Windows standard colors.
Thankfully, PHP developers aren't "Camel case bigots" like some development communities I know.
Your conventions sound fine.
Just so long as they're a) simple, and b) consistent - I don't see any problems :)
PS: Personally, I think 5) is overkill...
If you installed MySQL from brew
it really does only listen on the local interface by default. To fix that you need to edit /usr/local/etc/my.cnf
and change the bind-address
from 127.0.0.1
to *
.
Then run brew services restart mysql
.
If you experience this problem during the restore of a big dump-file and can rule out the problem that it has anything to do with network (e.g. execution on localhost) than my solution could be helpful.
My mysqldump held at least one INSERT that was too big for mysql to compute. You can view this variable by typing show variables like "net_buffer_length";
inside your mysql-cli.
You have three possibilities:
--skip-extended-insert
, per insert one line is used -> although these dumps are much nicer to read this is not suitable for big dumps > 1GB because it tends to be very slow--net-buffer_length NR_OF_BYTES
where NR_OF_BYTES is smaller than the server's net_buffer_length -> I think this is the best solution, although slower no server restart is needed.I used following mysqldump command:
mysqldump --skip-comments --set-charset --default-character-set=utf8 --single-transaction --net-buffer_length 4096 DBX > dumpfile
The main reason why the error has been generated is because there is already an existing value of 1
for the column ID
in which you define it as PRIMARY KEY
(values are unique) in the table you are inserting.
Why not set the column ID
as AUTO_INCREMENT
?
CREATE TABLE IF NOT EXISTS `PROGETTO`.`UFFICIO-INFORMAZIONI` (
`ID` INT(11) NOT NULL AUTO_INCREMENT,
`viale` VARCHAR(45) NULL ,
.....
and when you are inserting record, you can now skip the column ID
INSERT INTO `PROGETTO`.`UFFICIO-INFORMAZIONI` (`viale`, `num_civico`, ...)
VALUES ('Viale Cogel ', '120', ...)
it might be due to running of xampp or wampp server stop all services running and try to open mysql command line
I know that there are a lot of answers to this question already already but i wanted to share my experience as none of the answers provided fixed this issue for me.
After about a day of exploring different solutions I believe the issue was that I have recently installed XAMPP and it was interfering with the MySQL workbench. I have tried changing the port numbers however this hasn't helped, and it seems that both programs are sharing configuration files. Repairing MySQL in the Control Panel didn't resolve it, so now I am uninstalling MySQL and plan to reinstall it. Another potential solution maybe to uninstall XAMPP however the config files may either be deleted, or left in the xampp folder instead of the MySQL folder by doing so.
I solved this problem by installing MySQL 5.7:
First of all, You need to enable MySQL 5.7 community release yum repository on your system. The rpm packages for yum repository configuration are available on MySQL official website. Use on of below command as per your operating system version.
yum localinstall https://dev.mysql.com/get/mysql57-community-release-el7-9.noarch.rpm
yum localinstall https://dev.mysql.com/get/mysql57-community-release-el6-9.noarch.rpm
dnf install https://dev.mysql.com/get/mysql57-community-release-fc27-9.noarch.rpm
dnf install https://dev.mysql.com/get/mysql57-community-release-fc26-9.noarch.rpm
dnf install https://dev.mysql.com/get/mysql57-community-release-fc25-9.noarch.rpm
As you have successfully enabled MySQL yum repository on your system. Now, install MySQL 5.7 community server using following commands as per your operating system version.
yum install mysql-community-server
dnf install mysql-community-server
I don't have the reputation yet to up vote Steve's suggestion, but it solved my problem.
In my case, I received this error because the two table where created using different database engines--one was Innodb and the other MyISAM.
You can change the database type using : ALTER TABLE t ENGINE = MYISAM;
@see http://dev.mysql.com/doc/refman/5.1/en/storage-engine-setting.html
Q#1: I would guess that it's somewhere on your MySQL server? Q#2: Yes, this is possible. You have to establish a connection via Server Administration. There you can clone any table or the entire database.
This tutorial might be useful.
EDIT
Since the provided link is no longer active, here's a SO answer outlining the process of creating a DB backup in Workbench.
Try restarting the mysql or starting it if it wasn't started already. Type this within terminal.
mysql.server restart
To auto start go to the following link below:
How to auto-load MySQL on startup on OS X Yosemite / El Capitan
You have to open database connection, not workbench file with schema. It looks a bit wierd, but it makes sense when you realize what you are editing.
So, go to home tab, double click database connection (create it if you don't have it yet) and have fun.
If you'd prefer to do it in SQL, enter this query into the query window:
CREATE SCHEMA Test
Press CTRL + Enter to submit it, and you should see confirmation in the output pane underneath the query window. You'll have to right-click on an existing schema in the Object panel and click "Refresh All" to see it show up, though.
I assume that there exist some internal psql command for this, but you could also run the script
command from util-linux-ng package:
DESCRIPTION Script makes a typescript of everything printed on your terminal.
In SQL, a comparison between a null
value and any other value (including another null
) using a comparison operator (eg =
, !=
, <
, etc) will result in a null
, which is considered as false
for the purposes of a where clause (strictly speaking, it's "not true", rather than "false", but the effect is the same).
The reasoning is that a null
means "unknown", so the result of any comparison to a null
is also "unknown". So you'll get no hit on rows by coding where my_column = null
.
SQL provides the special syntax for testing if a column is null
, via is null
and is not null
, which is a special condition to test for a null
(or not a null
).
Here's some SQL showing a variety of conditions and and their effect as per above.
create table t (x int, y int);
insert into t values (null, null), (null, 1), (1, 1);
select 'x = null' as test , x, y from t where x = null
union all
select 'x != null', x, y from t where x != null
union all
select 'not (x = null)', x, y from t where not (x = null)
union all
select 'x = y', x, y from t where x = y
union all
select 'not (x = y)', x, y from t where not (x = y);
returns only 1 row (as expected):
TEST X Y
x = y 1 1

You almost never want to use Read Uncommited
since it's not really ACID
compliant. Read Commmited
is a good default starting place. Repeatable Read
is probably only needed in reporting, rollup or aggregation scenarios. Note that many DBs, postgres included don't actually support Repeatable Read, you have to use Serializable
instead. Serializable
is useful for things that you know have to happen completely independently of anything else; think of it like synchronized
in Java. Serializable goes hand in hand with REQUIRES_NEW
propagation.
I use REQUIRES
for all functions that run UPDATE or DELETE queries as well as "service" level functions. For DAO level functions that only run SELECTs, I use SUPPORTS
which will participate in a TX if one is already started (i.e. being called from a service function).
A Build Lifecycle is Made Up of Phases
Each of these build lifecycles is defined by a different list of build phases, wherein a build phase represents a stage in the lifecycle.
For example, the default lifecycle comprises of the following phases (for a complete list of the lifecycle phases, refer to the Lifecycle Reference):
These lifecycle phases (plus the other lifecycle phases not shown here) are executed sequentially to complete the default lifecycle. Given the lifecycle phases above, this means that when the default lifecycle is used, Maven will first validate the project, then will try to compile the sources, run those against the tests, package the binaries (e.g. jar), run integration tests against that package, verify the integration tests, install the verified package to the local repository, then deploy the installed package to a remote repository.

There is the Windows API Code Pack. It's got a lot of shell related stuff, including the CommonOpenFileDialog
class (in the Microsoft.WindowsAPICodePack.Dialogs
namespace). This is the perfect solution - the usual open dialog with only folders displayed.
Here is an example of how to use it:
CommonOpenFileDialog cofd = new CommonOpenFileDialog();
cofd.IsFolderPicker = true;
cofd.ShowDialog();
Unfortunately Microsoft no longer ships this package, but several people have unofficially uploaded binaries to NuGet. One example can be found here. This package is just the shell-specific stuff. Should you need it, the same user has several other packages which offer more functionality present in the original package.
In case of Homebrew, the directory for data files is /usr/local/var/mysql
to see which my.cnf file is used here are the search locations from my environment /etc/my.cnf /etc/mysql/my.cnf /usr/local/etc/my.cnf ~/.my.cnf
So to clean up this error I did the following

First, there is no such thing as a JSON object. JSON is a string format that can be used as a representation of a Javascript object literal.
Since JSON is a string, Javascript will treat it like a string, and not like an object (or array or whatever you are trying to use it as.)
Here is a good JSON reference to clarify this difference:
http://benalman.com/news/2010/03/theres-no-such-thing-as-a-json/
So if you need accomplish the task mentioned in your question, you must convert the JSON string to an object or deal with it as a string, and not as a JSON array. There are several libraries to accomplish this. Look at http://www.json.org/js.html for a reference.
Rather than adding libraries which increases your apk size, I will suggest you to convert Svg to drawable using http://inloop.github.io/svg2android/ .

If you look at the output you receive from print()
and also in your Traceback, you'll see the value you get back is not a string, it's a bytes object (prefixed by b
):
b'{\n "note":"This file .....
If you fetch the URL using a tool such as curl -v
, you will see that the content type is
Content-Type: application/json; charset=utf-8
So it's JSON, encoded as UTF-8, and Python is considering it a byte stream, not a simple string. In order to parse this, you need to convert it into a string first.
Change the last line of code to this:
info = json.loads(js.decode("utf-8"))

The old version of jQuery Cookie has been deprecated, so if you're getting the error:

you should upgrade to the new version.
The API for the new version is also different - rather than using

you should use
Cookies.get("yourCookieName");

You're on the right track. The two constructors accept arguments, or you can specify them post-construction with ProcessBuilder#command(java.util.List)

Using this code you can write to a text file in the SDCard. Along with it, you need to set a permission in the Android Manifest.
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
This is the code :
public void generateNoteOnSD(Context context, String sFileName, String sBody) {
try {
File root = new File(Environment.getExternalStorageDirectory(), "Notes");
if (!root.exists()) {
root.mkdirs();
}
File gpxfile = new File(root, sFileName);
FileWriter writer = new FileWriter(gpxfile);
writer.append(sBody);
writer.flush();
writer.close();
Toast.makeText(context, "Saved", Toast.LENGTH_SHORT).show();
} catch (IOException e) {
e.printStackTrace();
}
}
Before writing files you must also check whether your SDCard is mounted & the external storage state is writable.
Environment.getExternalStorageState()
Your approach is not bad, but it does have two issues: it swallows errors and it employs the Explicit Promise Construction Antipattern.
You can solve both of these issues, and make the code cleaner, while still employing the same general strategy:
var Q = require("q");
var readFile = function(file) {
... // Returns a promise.
};
var readFiles = function(files) {
var readSequential = function(index) {
if (index < files.length) {
return readFile(files[index]).then(function() {
return readSequential(index + 1);
});
}
};
// using Promise.resolve() here in case files.length is 0
return Promise.resolve(readSequential(0)); // Start!
};
The scalar formatter supports collecting the exponents. The docs are as follows:
class matplotlib.ticker.ScalarFormatter(useOffset=True, useMathText=False, useLocale=None) Bases: matplotlib.ticker.Formatter
Tick location is a plain old number. If useOffset==True and the data range is much smaller than the data average, then an offset will be determined such that the tick labels are meaningful. Scientific notation is used for data < 10^-n or data >= 10^m, where n and m are the power limits set using set_powerlimits((n,m)). The defaults for these are controlled by the axes.formatter.limits rc parameter.
your technique would be:
from matplotlib.ticker import ScalarFormatter
xfmt = ScalarFormatter()
xfmt.set_powerlimits((-3,3)) # Or whatever your limits are . . .
{{ Make your plot }}
gca().xaxis.set_major_formatter(xfmt)
To get the exponent displayed in the format x10^5
, instantiate the ScalarFormatter with useMathText=True
.
You could also use:
xfmt.set_useOffset(10000)
To get a result like this:
On Windows, 'b' appended to the mode opens the file in binary mode, so there are also modes like 'rb', 'wb', and 'r+b'. Python on Windows makes a distinction between text and binary files; the end-of-line characters in text files are automatically altered slightly when data is read or written. This behind-the-scenes modification to file data is fine for ASCII text files, but it’ll corrupt binary data like that in JPEG or EXE files. Be very careful to use binary mode when reading and writing such files. On Unix, it doesn’t hurt to append a 'b' to the mode, so you can use it platform-independently for all binary files.

MySQL uses CONCAT() to concatenate strings
SELECT * FROM tableOne
LEFT JOIN tableTwo
ON tableTwo.query = CONCAT('category_id=', tableOne.category_id)
Firstly, your example is looking quite correct and works well on my machine. You may go another way.
curl $CURLARGS $RVMHTTP > ./install.sh

If you're getting this error with react native, it may be due to a link to an NPM package that you removed (as it was in my case). After removing references to it in the settings.gradle and build.gradle files, I cleaned and rebuilt and it's as good as new :)
to find the program you want you can run this command at terminal:
find / usr-name "your_program"
<input type= "image" id=" " onclick=" " src=" " />
it works.
git reset HEAD^
then the modified files should show up.
You could move the modified files into a new branch
use,
git checkout -b newbranch
git checkout commit -m "files modified"
git push origin newbranch
git checkout master
then you should be on a clean branch, and your changes should be stored in newbranch. You could later just merge this change into the master branch
okay one other solution that I thought of just for the fun of it would be to turn your decimal into a string and then cut the string into 2 strings, one containing the point and the decimals and the other containing the Int to the left of the point. after that you limit the String of the point and decimals to 3 chars, one for the decimal point and the others for the decimals. then just recombine.
double shippingCost = ((nCartons * 1.44) + (lbs + 1) * 0.96) + 3.0;
String ShippingCost = (String) shippingCost;
String decimalCost = ShippingCost.subString(indexOf('.'),ShippingCost.Length());
ShippingCost = ShippingCost.subString(0,indexOf('.'));
ShippingCost = ShippingCost + decimalCost;
There! Simple, right?

Turns out that the post (or rather the whole table) was locked by the very same connection that I tried to update the post with.
I had a opened record set of the post that was created by:
Set RecSet = Conn.Execute()
This type of recordset is supposed to be read-only and when I was using MS Access as database it did not lock anything. But apparently this type of record set did lock something on MS SQL Server 2012 because when I added these lines of code before executing the UPDATE SQL statement...
RecSet.Close
Set RecSet = Nothing
...everything worked just fine.
So bottom line is to be careful with opened record sets - even if they are read-only they could lock your table from updates.
No, unlike in a lot of other languages, XSLT variables cannot change their values after they are created. You can however, avoid extraneous code with a technique like this:
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" indent="yes" omit-xml-declaration="yes"/>
<xsl:variable name="mapping">
<item key="1" v1="A" v2="B" />
<item key="2" v1="X" v2="Y" />
</xsl:variable>
<xsl:variable name="mappingNode"
select="document('')//xsl:variable[@name = 'mapping']" />
<xsl:template match="....">
<xsl:variable name="testVariable" select="'1'" />
<xsl:variable name="values" select="$mappingNode/item[@key = $testVariable]" />
<xsl:variable name="variable1" select="$values/@v1" />
<xsl:variable name="variable2" select="$values/@v2" />
</xsl:template>
</xsl:stylesheet>
In fact, once you've got the values
variable, you may not even need separate variable1
and variable2
variables. You could just use $values/@v1

Here's how I find valid 10-digit US phone numbers. At this point I'm assuming the user wants my content so the numbers themselves are trusted. I'm using in an app that ultimately sends an SMS message so I just want the raw numbers no matter what. Formatting can always be added later
//eliminate every char except 0-9
$justNums = preg_replace("/[^0-9]/", '', $string);
//eliminate leading 1 if its there
if (strlen($justNums) == 11) $justNums = preg_replace("/^1/", '',$justNums);
//if we have 10 digits left, it's probably valid.
if (strlen($justNums) == 10) $isPhoneNum = true;
Edit: I ended up having to port this to Java, if anyone's interested. It runs on every keystroke so I tried to keep it fairly light:
boolean isPhoneNum = false;
if (str.length() >= 10 && str.length() <= 14 ) {
//14: (###) ###-####
//eliminate every char except 0-9
str = str.replaceAll("[^0-9]", "");
//remove leading 1 if it's there
if (str.length() == 11) str = str.replaceAll("^1", "");
isPhoneNum = str.length() == 10;
}
Log.d("ISPHONENUM", String.valueOf(isPhoneNum));
I found a quite simple solution, because for me it was just a design issue. I wanted the rest of the Page not to be white below the red footer. So i set the pages background color to red. And the contents backgroundcolor to white. With the contents height set to eg. 20em or 50% an almost empty page won't leave the whole page red.
You want rows where that condition is true so you need a comma:
data[data$Ozone > 14, ]
in XML: android:textAllCaps="false"
Programmatically:
mbutton.setAllCaps(false);
Constraintlayout is the Default for a new app. I am "learning to Android" now and had a very hard time figuring out how to handle the default "sample" code to scroll when a keyboard is up. I have seen many apps where I have to close the keyboard to click "submit" button and sometimes it does not goes away. Using this [ScrollView / ContraintLayout / Fields] hierarchy it is working just fine now. This way we can have the benefits and ease of use from ConstraintLayout in a scrollable view.
Was able to find a solution. Ran the following as specified at http://technoguider.com/2015/05/utf8-set-up-in-mysql/
SET NAMES UTF8;
set collation_server = utf8_general_ci;
set default-character-set = utf8;
set init_connect = ’SET NAMES utf8';
set character_set_server = utf8;
set character_set_client = utf8;
Your font
tag is not correct, so it won't work in some browsers. The px
unit is used with CSS, not HTML attributes. The font tag should look like this:
<font size="100">
Well, actually it shouldn't be there at all. The font
tag is deprecated, you should use CSS to style the content, like you do already with the text-decoration
:
<a href="selectTopic?html" style="font-size: 100px; text-decoration: none">HTML 5</a>
To separate the content from the styling, you should of course work towards putting the CSS in a style sheet rather than as inline style
attributes. That way you can apply one style to several elements without having to put the same style
attribute in all of them.
Example:
<a href="selectTopic?html" class="topic">HTML 5</a>
CSS:
.topic { font-size: 100px; text-decoration: none; }
To get your solution try this
string directory = System.IO.Directory.GetParent(System.IO.Directory.GetParent(Environment.CurrentDirectory).ToString()).ToString();
This is from the msdn article here:
https://blogs.msdn.microsoft.com/tomarcher/2006/05/10/are-hash-codes-unique/
"While you will hear people state that hash codes generate a unique value for a given input, the fact is that, while difficult to accomplish, it is technically feasible to find two different data inputs that hash to the same value. However, the true determining factors regarding the effectiveness of a hash algorithm lie in the length of the generated hash code and the complexity of the data being hashed."
So just use a hash algorithm suitable to your data size and it will have unique hashcodes.

"How do I do that? I explored PHPMyAdmin, and I can't find a "change engine" functionality."
In direct response to this part of your question, you can issue an ALTER TABLE tbl engine=InnoDB;
and it'll recreate the table in the proper engine.
After some tests, I can say the following:
[UIApplication sharedApplication]
will cause the app looking like it crashed, BUT it will call - (void)applicationWillTerminate:(UIApplication *)application
before doing so;exit(0);
will also terminate the application, but it will look "normal" (the springboard's icons appears like expected, with the zoom out effect), BUT it won't call the - (void)applicationWillTerminate:(UIApplication *)application
delegate method.My advice:
- (void)applicationWillTerminate:(UIApplication *)application
on the delegate.exit(0);
.space is used to make multiple classes:
<div class="One Two Three"> </div>
You should use @RequestParam
on those resources with method = RequestMethod.GET
In order to post parameters, you must send them as the request body. A body like JSON or another data representation would depending on your implementation (I mean, consume and produce MediaType
).
Typically, multipart/form-data is used to upload files.
You could change your iframe to be like this and add origin to be your current website. It resolves error on my browser.

In the spring jar package, I use new ClassPathResource(filename).getFile()
, which throws the exception:
cannot be resolved to absolute file path because it does not reside in the file system: jar
But using new ClassPathResource(filename).getInputStream()
will solve this problem. The reason is that the configuration file in the jar does not exist in the operating system's file tree,so must use getInputStream()
.
Posting this as an equally viable alternative to @Binil Thomas's answer - tried to add it as a comment, but was not convinced of the readability of it all.

If you are using Android then you can use android.util.Base64

Encode:
passwd = Base64.encodeToString( passwd.getBytes(), Base64.DEFAULT );
Decode:

What about trying with VLOOKUP
? The syntax is:
=VLOOKUP(cell you want to copy, range you want to copy, 1, FALSE).
It should do the trick.
This is an old thread but I was surprised nobody mentioned grep. The -A option allows specifying a number of lines to print after a search match and the -B option includes lines before a match. The following command would output 10 lines before and 10 lines after occurrences of "my search string" in the file "mylogfile.log":
grep -A 10 -B 10 "my search string" mylogfile.log
If there are multiple matches within a large file the output can rapidly get unwieldy. Two helpful options are -n which tells grep to include line numbers and --color which highlights the matched text in the output.
If there is more than file to be searched grep allows multiple files to be listed separated by spaces. Wildcards can also be used. Putting it all together:
grep -A 10 -B 10 -n --color "my search string" *.log someOtherFile.txt
Use eval
. It takes JavaScript expression/code as string and evaluates/executes it.
eval(inputString);
Your textbox code:
<input type="text" class="textboxclass" />
Your CSS code:
input[type="text"] {
height: 10px;
width: 80px;
}
or
.textboxclass {
height: 10px;
width: 80px;
}
So, first you select your element with attributes (look at first example) or classes(look last example). Later, you assign height and width values to your element.
The matrix you pasted
[[ 1, 8, 50],
[ 8, 64, 400],
[ 50, 400, 2500]]
Has a determinant of zero. This is the definition of a Singular matrix (one for which an inverse does not exist)
We do it differently. IMHO we do it in an easier way: in master
we are working on the next major version.
Each larger feature gets its own branch (derived from master) and will be rebased (+ force pushed) on top of master regularly by the developer. Rebasing only works fine if a single developer works on this feature. If the feature is finished, it will be freshly rebased onto master and then the master fast-forwarded to the latest feature commit.
To avoid the rebasing/forced push one also can merge master changes regularly to the feature branch and if it's finished merge the feature branch into master (normal merge or squash merge). But IMHO this makes the feature branch less clear and makes it much more difficult to reorder/cleanup the commits.
If a new release is coming, we create a side-branch out of master, e.g. release-5
where only bugs get fixed.
Another way to phrase the same idea:
If speeding up the CPU doesn't speed up your program, it may be I/O bound.
If speeding up the I/O (e.g. using a faster disk) doesn't help, your program may be CPU bound.
(I used "may be" because you need to take other resources into account. Memory is one example.)
<div ng-class="{'has-error': userForm.mobileno.$error.pattern ,'has-success': userForm.mobileno.$valid}">
<input type="text" name="mobileno" ng-model="mobileno" ng-pattern="/^[7-9][0-9]{9}$/" required>
Here "userForm" is my form name.
How about:
<meta http-equiv="refresh" content="5;url=http://site.com/file.ext">
This way works on all browsers (i think) and let you put a message like: "If the download doesn't start in five seconds, click here."
If you need it to be with javascript.. well...
document.write('<meta http-equiv="refresh" content="5;url=http://site.com/file.ext">');

I was facing the same problem with wireMock while mocking the rest API calls. Earlier I was defining the server like this:
WireMockServer wireMockServer = null;
But it should be defined like as shown below:
@Rule
public WireMockRule wireMockRule = new WireMockRule(8089);
Here's a simple way to do it that I don't see in the other answers.
To round up to the second decimal place:
>>> n = 0.022499999999999999
>>>
>>> -(-n//.01) * .01
0.03
>>>
Other value:
>>> n = 0.1111111111111000
>>>
>>> -(-n//.01) * .01
0.12
>>>
With floats there's the occasional value with some minute imprecision, which can be corrected for if you're displaying the values for instance:
>>> n = 10.1111111111111000
>>>
>>> -(-n//0.01) * 0.01
10.120000000000001
>>>
>>> f"{-(-n//0.01) * 0.01:.2f}"
'10.12'
>>>
A simple roundup function with a parameter to specify precision:
>>> roundup = lambda n, p: -(-n//10**-p) * 10**-p
>>>
>>> # Or if you want to ensure truncation using the f-string method:
>>> roundup = lambda n, p: float(f"{-(-n//10**-p) * 10**-p:.{p}f}")
>>>
>>> roundup(0.111111111, 2)
0.12
>>> roundup(0.111111111, 3)
0.112
$('.offer').click(function(){
if ($(this).find(':checkbox').is(':checked'))
{
$(this).find(':checkbox').attr('checked', false);
}else{
$(this).find(':checkbox').attr('checked', true);
}
});
Square brackets are lists while parentheses are tuples.
A list is mutable, meaning you can change its contents:
>>> x = [1,2]
>>> x.append(3)
>>> x
[1, 2, 3]
while tuples are not:
>>> x = (1,2)
>>> x
(1, 2)
>>> x.append(3)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: 'tuple' object has no attribute 'append'
The other main difference is that a tuple is hashable, meaning that you can use it as a key to a dictionary, among other things. For example:
>>> x = (1,2)
>>> y = [1,2]
>>> z = {}
>>> z[x] = 3
>>> z
{(1, 2): 3}
>>> z[y] = 4
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: unhashable type: 'list'
Note that, as many people have pointed out, you can add tuples together. For example:
>>> x = (1,2)
>>> x += (3,)
>>> x
(1, 2, 3)
However, this does not mean tuples are mutable. In the example above, a new tuple is constructed by adding together the two tuples as arguments. The original tuple is not modified. To demonstrate this, consider the following:
>>> x = (1,2)
>>> y = x
>>> x += (3,)
>>> x
(1, 2, 3)
>>> y
(1, 2)
Whereas, if you were to construct this same example with a list, y
would also be updated:
>>> x = [1, 2]
>>> y = x
>>> x += [3]
>>> x
[1, 2, 3]
>>> y
[1, 2, 3]
Yes there is a difference between the functions but the way you are using them in this case will result in the same outcome.
path.join
returns a normalized path by merging two paths together. It can return an absolute path, but it doesn't necessarily always do so.
For instance:
path.join('app/libs/oauth', '/../ssl')
resolves to app/libs/ssl
path.resolve
, on the other hand, will resolve to an absolute path.
For instance, when you run:
path.resolve('bar', '/foo');
The path returned will be /foo
since that is the first absolute path that can be constructed.
However, if you run:
path.resolve('/bar/bae', '/foo', 'test');
The path returned will be /foo/test
again because that is the first absolute path that can be formed from right to left.
If you don't provide a path that specifies the root directory then the paths given to the resolve
function are appended to the current working directory. So if your working directory was /home/mark/project/
:
path.resolve('test', 'directory', '../back');
resolves to
/home/mark/project/test/back
Using __dirname
is the absolute path to the directory containing the source file. When you use path.resolve
or path.join
they will return the same result if you give the same path following __dirname
. In such cases it's really just a matter of preference.

There are two common ways of writing to a file, the first being a direct file access "write" statement. This adds the quotes.
The second is the "ActiveWorkbook.SaveAs" or "ActiveWorksheet.SaveAs" which both have the really bad side effect of changing the filename of the active workbook.
The solution here is a hybrid of a few solutions I found online. It basically does this: 1) Copy selected cells to a new worksheet 2) Iterate through each cell one at a time and "print" it to the open file 3) Delete the temporary worksheet.
The function works on the selected cells and takes in a string for a filename or prompts for a filename.
Function SaveFile(myFolder As String) As String
tempSheetName = "fileWrite_temp"
SaveFile = "False"
Dim FilePath As String
Dim CellData As String
Dim LastCol As Long
Dim LastRow As Long
Set myRange = Selection
'myRange.Select
Selection.Copy
'Ask user for folder to save text file to.
If myFolder = "prompt" Then
myFolder = Application.GetSaveAsFilename(fileFilter:="XML Files (*.xml), *.xml, All Files (*), *")
End If
If myFolder = "False" Then
End
End If
Open myFolder For Output As #2
'This temporarily adds a sheet named "Test."
Sheets.Add.Name = tempSheetName
Sheets(tempSheetName).Select
Selection.PasteSpecial Paste:=xlPasteValues, Operation:=xlNone, SkipBlanks _
:=False, Transpose:=False
LastCol = ActiveSheet.UsedRange.SpecialCells(xlCellTypeLastCell).Column
LastRow = ActiveSheet.UsedRange.SpecialCells(xlCellTypeLastCell).Row
For i = 1 To LastRow
For j = 1 To LastCol
CellData = CellData + Trim(ActiveCell(i, j).Value) + " "
Next j
Print #2, CellData; " "
CellData = ""
Next i
Close #2
'Remove temporary sheet.
Application.ScreenUpdating = False
Application.DisplayAlerts = False
ActiveWindow.SelectedSheets.Delete
Application.DisplayAlerts = True
Application.ScreenUpdating = True
'Indicate save action.

SaveFile = myFolder

FloatingActionButton
extends ImageView
. So, it's simple as like introducing an ImageView
in your layout. Here is an XML sample.
<android.support.design.widget.FloatingActionButton xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/somedrawable"
android:layout_gravity="right|bottom"
app:borderWidth="0dp"
app:rippleColor="#ffffff"/>
app:borderWidth="0dp"
is added as a workaround for elevation issues.
The server SHOULD put double quotes around the filename, as mentioned by @cusman and @Touko in their replies.
For example:
Response.AddHeader("Content-Disposition", "attachment;filename=\"" + filename + "\"");
$_GET['start_date']
is not numeric is my bet, but an date format not supported by strtotime
. You will need to re-format the date to a workable format for strtotime or use combination of explode/mktime.
I could add you an example if you'd be kind enough to post the format you currently receive.
People have mentioned make
but bjam
also supports a similar concept. Using bjam -jx
instructs bjam to build up to x
concurrent commands.
We use the same build scripts on Windows and Linux and using this option halves our build times on both platforms. Nice.

Checking for null
within if
statement prevents Laravel from returning 404 immediately after the query is over.
if ( User::find( $userId ) === null ) {
return "user does not exist";
}
else {
$user = User::find( $userId );
return $user;
}
It seems like it runs double query if the user is found, but I can't seem to find any other reliable solution.
Google has released a Native Development Kit (NDK) (according to http://www.youtube.com/watch?v=Z5whfaLH1-E at 00:07:30).
Hopefully the information will be updated on the google groups page (http://groups.google.com/group/android-ndk), as it says it hasn't been released yet.
I'm not sure where to get a simple download for it, but I've heard that you can get a copy of the NDK from Google's Git repository under the donut branch.
Another way is to use an array as a type, e.g.:
MyClass[] mcArray = gson.fromJson(jsonString, MyClass[].class);
This way you avoid all the hassle with the Type object, and if you really need a list you can always convert the array to a list by:
List<MyClass> mcList = Arrays.asList(mcArray);
IMHO this is much more readable.
And to make it be an actual list (that can be modified, see limitations of Arrays.asList()
) then just do the following:
List<MyClass> mcList = new ArrayList<>(Arrays.asList(mcArray));
If you already have your SSH keys set up and are still getting the password prompt, make sure your repo URL is in the form
git+ssh://[email protected]/username/reponame.git
as opposed to

To see your repo URL, run:
git remote show origin
You can change the URL with git remote set-url
like so:
git remote set-url origin git+ssh://[email protected]/username/reponame.git

string fileName = System.IO.Path.GetTempPath() + Guid.NewGuid().ToString() + ".csv";
(To quote from the wiki article on the probabilty of a collision:
...one's annual risk of being hit by a meteorite is estimated to be one chance in 17 billion [19], that means the probability is about 0.00000000006 (6 × 10-11), equivalent to the odds of creating a few tens of trillions of UUIDs in a year and having one duplicate. In other words, only after generating 1 billion UUIDs every second for the next 100 years, the probability of creating just one duplicate would be about 50%. The probability of one duplicate would be about 50% if every person on earth owns 600 million UUIDs

This post has helped me a lot, and after a few iterations, this is what we use.
The idea is to post log messages and errors to HTML, for example if you need to debug JS and don't have access to the console.
You do need to change 'console.log' with 'logThis', as it is not recommended to change native functionality.
What you'll get:
function logThis(message) {
// if we pass an Error object, message.stack will have all the details, otherwise give us a string
if (typeof message === 'object') {
message = message.stack || objToString(message);
}
console.log(message);
// create the message line with current time
var today = new Date();
var date = today.getFullYear() + '-' + (today.getMonth() + 1) + '-' + today.getDate();
var time = today.getHours() + ':' + today.getMinutes() + ':' + today.getSeconds();
var dateTime = date + ' ' + time + ' ';
//insert line
document.getElementById('logger').insertAdjacentHTML('afterbegin', dateTime + message + '<br>');
}
function objToString(obj) {
var str = 'Object: ';
for (var p in obj) {
if (obj.hasOwnProperty(p)) {
str += p + '::' + obj[p] + ',\n';
}
}
return str;
}
const object1 = {
a: 'somestring',
b: 42,
c: false
};
logThis(object1)
logThis('And all the roads we have to walk are winding, And all the lights that lead us there are blinding')

Thanks this answer too, JSON.stringify() didn't work for this.
i do this:
select isnull((select top 1 1 from inserted t1),0) + isnull((select top 1 2 from deleted t1),0)
1 -> insert
2 -> delete
3 -> update
set @i = isnull((select top 1 1 from inserted t1),0) + isnull((select top 1 2 from deleted t1),0)
--select @i
declare @action varchar(1) = case @i when 1 then 'I' when 2 then 'D' when 3 then 'U' end
--select @action
select @action c1,* from inserted t1 where @i in (1,3) union all
select @action c1,* from deleted t1 where @i in (2)
I think the problem is not in sub-query but in WHERE clause of outer query. When you use
WHERE account_code between 503100 and 503105
SQL server will try to convert every value in your Account_code field to integer to test it in provided condition. Obviously it will fail to do so if there will be non-integer characters in some rows.
I had the same issue. After running
pod install
Setting up CocoaPods master repo
The iterm2 was stuck on Setting up CocoaPods.
I solved the issue by running
sudo gem install CocoaPods
This is mentioned in the CocoaPods website
python -m pip install --upgrade pip
I've found that this can happen due to a number of various reasons.
In my case when I scroll to the end of the SQL import "Report", under the "Post-execute (Success)" heading it will tell me how many rows were copied and it's usually the next row in sheet which has the issue. Also you can tell which column by the import messages (in your case it was "Copy of F2") so you can generally find out which was the offending cell in Excel.
I've seen this happen for very silly reasons such as the date format in Excel being different than previous rows. For example cell A2 being "05/02/2017" while A3 being "5/2/2017" or even "05-02-2017". It seems the import wants things to be perfectly consistent.
It even happens if the Excel formats are different so if B2 is "512" but an Excel "Number" format and B3 is "512" but an Excel "Text" format then the Cell will cause an error.
I've also had situations where I literally had to delete all the "empty" rows below my data rows in the Excel sheet. Sometimes they appear empty but Excel considers them having "blank" data or something like that so the import tries to import them as well. This usually happens if you've had previous data in your Excel sheet which you've cleared but haven't properly deleted the rows.
And then there's the obvious reasons of trying to import text value into an integer column or insert a NULL into a NOT NULL column as mentioned by the others.
The problem is that the first argument passed to class methods in python is always a copy of the class instance on which the method is called, typically labelled self
. If the class is declared thus:
class foo(object):
def foodo(self, thing=None, thong='not underwear'):
print thing if thing else "nothing"
print 'a thong is',thong
it behaves as expected.
Explanation:
Without self
as the first parameter, when myfoo.foodo(thing="something")
is executed, the foodo
method is called with arguments (myfoo, thing="something")
. The instance myfoo
is then assigned to thing
(since thing
is the first declared parameter), but python also attempts to assign "something"
to thing
, hence the Exception.
To demonstrate, try running this with the original code:
myfoo.foodo("something")
print
print myfoo
You'll output like:
<__main__.foo object at 0x321c290>
a thong is something
<__main__.foo object at 0x321c290>
You can see that 'thing' has been assigned a reference to the instance 'myfoo' of the class 'foo'. This section of the docs explains how function arguments work a bit more.
select db_name(), * From sysobjects where xtype in ('U', 'P') And name = 'OBJECT_name'
First column will display name of database where object is located at.
jsFunction is not in good closure. change to:
jsFunction = function(value)
{
alert(value);
}
and don't use global variables and functions, change it into module
EDIT:
This answer might not work depending if you're not targeting es5
anymore, I'll try to make the answer more complete.
Original Answer
If CommonJS isn't installed (which defines exports
), you have to remove this line from your tsconfig.json
:
"module": "commonjs",
As per the comments, this alone may not work with later versions of tsc
. If that is the case, you can install a module loader like CommonJS, SystemJS or RequireJS and then specify that.
Note:
Look at your main.js
file that tsc
generated. You will find this at the very top:
Object.defineProperty(exports, "__esModule", { value: true });
It is the root of the error message, and after removing "module": "commonjs",
, it will vanish.
The command has to be entered in the directory of the repository. The error is complaining that your current directory isn't a git repo
ls
show the right files?git init
? (git-init documentation)Either of those would cause your error.
Well to obtain all different values in a Dataframe
you can use distinct. As you can see in the documentation that method returns another DataFrame
. After that you can create a UDF
in order to transform each record.
For example:
val df = sc.parallelize(Array((1, 2), (3, 4), (1, 6))).toDF("age", "salary")
// I obtain all different values. If you show you must see only {1, 3}
val distinctValuesDF = df.select(df("age")).distinct
// Define your udf. In this case I defined a simple function, but they can get complicated.
val myTransformationUDF = udf(value => value / 10)
// Run that transformation "over" your DataFrame
val afterTransformationDF = distinctValuesDF.select(myTransformationUDF(col("age")))
You are recursively defining x
with x
. As if someone asks you how old are you? And you answer "I am twice my age". Which is meaningless.
You must say I am twice John's age or any other variable but yourself.
computed variables are always dependent on another variable.
The rule of the thumb is never access the property itself from within the getter ie get
. Because that would trigger another get
which would trigger another . . . Don't even print it. Because printing also requires to 'get' the value before it can print it!
struct Person{
var name: String{
get{
print(name) // DON'T do this!!!!
return "as"
}
set{
}
}
}
let p1 = Person()
As that would give the following warning:
Attempting to access 'name' from within it's own getter.
The error looks vague like this:
As an alternative you might want to use didSet
. With didSet
you'll get a hold to the value that is was set before and just got set to. For more see this answer.
To check is variable is set you need to use isset function.
$lorem = 'potato';
if(isset($lorem)){
echo 'isset true' . '<br />';
}else{
echo 'isset false' . '<br />';
}
if(isset($ipsum)){
echo 'isset true' . '<br />';
}else{
echo 'isset false' . '<br />';
}
this code will print:
isset true
isset false

You need a regular expression for this. Look here. If you are using .net Framework4.5 then you can also use this. As it is built in .net Framework 4.5. Example
[EmailAddress(ErrorMessage = "Invalid Email Address")]
public string Email { get; set; }
What worked for me in Eclipse Mars was to go to Window > Preferences > Web > HTML Files, and in the right panel in Encoding select ISO 10646/Unicode(UTF-8), Apply and OK, then and only then my .html files were created with .

You can easily install it using Anaconda. At first install Anaconda or Miniconda on you system (download from here) and then install the pyqt as follow:
conda install pyqt
It works for both version of python (2 and 3).
The DisplayHtml(string html) recommended by m3z worked for me.
In case it helps somebody, I would also like to mention that initially there were some spaces in my HTML that invalidated the HTML and so the text appeared as a string. The spaces were introduced (around the angular brackets) when I pasted the HTML into Visual Studio. So if your text is still appearing as text after you try the solutions mentioned in this post, then it may be worth checking that the HTML syntax is correct.
$(document).ready(function() {
$('#emailid').focusout(function(){
$('#emailid').filter(function(){
var email = $('#emailid').val();
var emailReg = /^([\w-\.]+@([\w-]+\.)+[\w-]{2,4})?$/;
if ( !emailReg.test( email ) ) {
alert('Please enter valid email');
} else {
alert('Thank you for your valid email');
}
});
});
});
The answer of Steve is correct, but it doesn't work for integers less than 1.
Here an updated version that does work for negatives:
int digits = n == 0 ? 1 : Math.Floor(Math.Log10(Math.Abs(n)) + 1)
Apart from the methods mentioned earlier. You can also use the command del to remove multiple variables
del variable1,variable2
temp = bankAccNos.contains(no) ? 1 : 2;
This is more pythonic
my_list = [0, 1, 2, 3, 4, 5] # some list
my_list_copy = list(my_list) # my_list_copy and my_list does not share reference now.
NOTE: This is not safe with a list of referenced objects
amap.find
returns amap::end
when it does not find what you're looking for -- you're supposed to check for that.
There is really nice package with few examples of usage called axios-cancel. I've found it very helpful. Here is the link: https://www.npmjs.com/package/axios-cancel
Generally the first step is to not do that in the first place, but if this is already done, then you need to resort to properly quoting your column names:
SELECT `Business Name` FROM annoying_table
Usually these sorts of things are created by people who have used something like Microsoft Access and always use a GUI to do their thing.
we can figure out that by not playing with opacity just by using rgba color
e.g "background-color: rgba(0,0,0, 0.5)"
Sample :
Previous Css:
.login-card {
// .... others CSS
background-color: #121e1b;
opacity: 0.5;
}
To :
.login-card {
// .... others CSS
background-color: rgba(0, 0, 0, 0.5);
}
Needed a break, so I cobbled the following together. Not sure it would be worth creating a plugin from though.

Make sure pom.xml exist in the directory, when using the mvn spring-boot:run command. No need to add any thing in the pom.xml file.
It's probably not very popular because it's not well known. I wouldn't be afraid of using it since all major browsers support it.
If your site uses AJAX you'll want to make sure all of your pages have it set correctly or you could end up with links that cannot be resolved.
Just don't use the target
attribute in an HTML 4.01 Strict page.
window.onload = function() {
... etc. is not a great answer.
This will likely work, but it will also break any other functions already hooking to that event. Or, if another function hooks into that event after yours, it will break yours. So, you can spend lots of hours later trying to figure out why something that was working isn't anymore.
A more robust answer here:
if(window.attachEvent) {
window.attachEvent('onload', yourFunctionName);
} else {
if(window.onload) {
var curronload = window.onload;
var newonload = function(evt) {
curronload(evt);
yourFunctionName(evt);
};
window.onload = newonload;
} else {
window.onload = yourFunctionName;
}
}
Some code I have been using, I forget where I found it to give the author credit.
function my_function() {
// whatever code I want to run after page load
}
if (window.attachEvent) {window.attachEvent('onload', my_function);}
else if (window.addEventListener) {window.addEventListener('load', my_function, false);}
else {document.addEventListener('load', my_function, false);}
Hope this helps :)
The great thing about yyyy-mm-dd
date format is that there is no need to extract month()
and year()
, you can do comparisons directly on strings:
SELECT *
FROM your_table
WHERE your_date_column >= '2010-09-01' AND your_date_column <= '2013-08-31';
It is not necessary.
No warning is generated if the variable does not exist. That means empty() is essentially the concise equivalent to !isset($var) || $var == false.
I'm using xdebug for watch this values in VSCode with the respective extension and CI v2.x. I add the expresion $this->db->last_query()
in the watch section, and I add xdebugSettings
node like these lines for get non truncate value in the launch.json.
{
"name": "Launch currently open script",
"type": "php",
"request": "launch",
"program": "${file}",
"cwd": "${fileDirname}",
"port": 9000,
"xdebugSettings": {
"max_data": -1,
"max_children": -1
}
},
And run my debuger with the breakpoint and finally just select my expresion and do click right > copy value.
How about using explode
:
$input = 'Posted On April 6th By Some Dude';
$result = explode(' By',$input);
return $result[0];
Advantages:
$result[1]
would return Some Dude
in this example)Encapsulation can be thought of as wrapping paper used to bind data and function together as a single unit which protects it from all kinds of external dirt (I mean external functions).
Abstraction involves absence of details and the use of a simple interface to control a complex system.
For example we can light a bulb by the pressing of a button without worrying about the underlying electrical engineering (Abstraction) .
However u cannot light the bulb in any other way. (Encapsulation)
Here is the easiest solution.
There are a lot of environment special configurations needed if you are using Maven. So, if you start your program from maven, just run the mvnDebug
command instead of mvn
, it will take care of starting your app with remote debugging configurated. Now you can just attach a debugger on port 8000.
It'll take care of all the environment problems for you.
Try to add this:
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_HTTPPROXYTUNNEL, 1);
You'll have to make a join:
SELECT A.SalesOrderID, B.Foo
FROM A
JOIN B bo ON bo.id = (
SELECT TOP 1 id
FROM B bi
WHERE bi.SalesOrderID = a.SalesOrderID
ORDER BY bi.whatever
)
WHERE A.Date BETWEEN '2000-1-4' AND '2010-1-4'
, assuming that b.id
is a PRIMARY KEY
on B
In MS SQL 2005
and higher you may use this syntax:
SELECT SalesOrderID, Foo
FROM (
SELECT A.SalesOrderId, B.Foo,
ROW_NUMBER() OVER (PARTITION BY B.SalesOrderId ORDER BY B.whatever) AS rn
FROM A
JOIN B ON B.SalesOrderID = A.SalesOrderID
WHERE A.Date BETWEEN '2000-1-4' AND '2010-1-4'
) i
WHERE rn
This will select exactly one record from B
for each SalesOrderId
.
This code works great nice

Design patterns aren't trivially reusable solutions.
Design patterns are reusable, by definition. They're patterns you detect in other good solutions.
A pattern is not trivially reusable. You can implement your down design following the pattern however.
Relational design patters include things like:
One-to-Many relationships (master-detail, parent-child) relationships using a foreign key.
Many-to-Many relationships with a bridge table.
Optional one-to-one relationships managed with NULLs in the FK column.
Star-Schema: Dimension and Fact, OLAP design.
Fully normalized OLTP design.
Multiple indexed search columns in a dimension.
"Lookup table" that contains PK, description and code value(s) used by one or more applications. Why have code? I don't know, but when they have to be used, this is a way to manage the codes.
Uni-table. [Some call this an anti-pattern; it's a pattern, sometimes it's bad, sometimes it's good.] This is a table with lots of pre-joined stuff that violates second and third normal form.
Array table. This is a table that violates first normal form by having an array or sequence of values in the columns.
Mixed-use database. This is a database normalized for transaction processing but with lots of extra indexes for reporting and analysis. It's an anti-pattern -- don't do this. People do it anyway, so it's still a pattern.
Most folks who design databases can easily rattle off a half-dozen "It's another one of those"; these are design patterns that they use on a regular basis.
And this doesn't include administrative and operational patterns of use and management.
According to MDN, "matchMedia" is the proper way to do this https://developer.mozilla.org/en-US/docs/Web/API/Window/devicePixelRatio#Monitoring_screen_resolution_or_zoom_level_changes
it's a bit finicky because each instance can only watch one MQ at a time, so if you're interested in any zoom level change you need to make a bunch of matchers.. but since the browser is in charge to emitting the events it's probably still more performant than polling, and you could throttle or debounce the callback or pin it to an animation frame or something - here's an implementation that seems pretty snappy, feel free to swap in _throttle or whatever if you're already depending on that.

I am not sure if this was possible in TypeScript when the question was originally asked, but my preferred solution is with generics:
class Zoo<T extends Animal> {
constructor(public readonly AnimalClass: new () => T) {
}
}
This way variables penguin
and lion
infer concrete type Penguin
or Lion
even in the TypeScript intellisense.
const penguinZoo = new Zoo(Penguin);
const penguin = new penguinZoo.AnimalClass(); // `penguin` is of `Penguin` type.
const lionZoo = new Zoo(Lion);
const lion = new lionZoo.AnimalClass(); // `lion` is `Lion` type.
On iOS, it currently does not matter if you use int
or NSInteger
. It will matter more if/when iOS moves to 64-bits.
Simply put, NSInteger
s are int
s in 32-bit code (and thus 32-bit long) and long
s on 64-bit code (long
s in 64-bit code are 64-bit wide, but 32-bit in 32-bit code). The most likely reason for using NSInteger
instead of long
is to not break existing 32-bit code (which uses int
s).
CGFloat
has the same issue: on 32-bit (at least on OS X), it's float
; on 64-bit, it's double
.
Update: With the introduction of the iPhone 5s, iPad Air, iPad Mini with Retina, and iOS 7, you can now build 64-bit code on iOS.
Update 2: Also, using NSInteger
s helps with Swift code interoperability.

That's a rather large question.
LDAP is a protocol for accessing a directory. A directory contains objects; generally those related to users, groups, computers, printers and so on; company structure information (although frankly you can extend it and store anything in there).
LDAP gives you query methods to add, update and remove objects within a directory (and a bunch more, but those are the central ones).
What LDAP does not do is provide a database; a database provides LDAP access to itself, not the other way around. It is much more than signup.

If input value can be in numeric form other than integer , check by
if (x == (int)x)
{
// Number is integer
}
If string value is being passed , use Integer.parseInt(string_var).
Please ensure error handling using try catch in case conversion fails.
I generally agree with solutions given above. Namely with:
for
-loop (2 and more lines)while
counter (3 and more lines)__nonzero__
implementation (many more lines) If one is to define an object as in #3 I would recommend implementing protocol for with keyword or apply contextlib.
Further I propose yet another solution. It is a 3 liner and is not of supreme elegance, but it uses itertools package and thus might be of an interest.
from itertools import (chain, repeat)
times = chain(repeat(True, 2), repeat(False))
while next(times):
print 'do stuff!'
In these example 2 is the number of times to iterate the loop. chain is wrapping two repeat iterators, the first being limited but the second is infinite. Remember that these are true iterator objects, hence they do not require infinite memory. Obviously this is much slower then solution #1. Unless written as a part of a function it might require a clean up for times variable.
You can create a configuration file named config
in your ~/.ssh

Host aws
HostName *yourip*

IdentityFile *idFile*
This will allow you to connect to machines like this

Top answer with most upvotes isn't wrong but still the opposite of what I would post. I say it will totally work to start an exe file and you can do this in the context of any user. Logically you just can't have any user interface or ask for user input...
Here is my advice:
Example to start e.g. plink.exe. You could even listen to the output:
var psi = new ProcessStartInfo()
{
FileName = "./Client/plink.exe", //path to your *.exe
Arguments = "-telnet -P 23 127.0.0.1 -l myUsername -raw", //arguments
RedirectStandardError = true,
RedirectStandardOutput = true,
RedirectStandardInput = true,
UseShellExecute = false,
CreateNoWindow = true //no window, you can't show it anyway
};
var p = Process.Start(psi);
I took LocalSystem account which is default and more than Local Service. It worked fine without having to enter login information of a specific user. I didn't even tick the checkbox "Allow service to interact with desktop" which you could if you need higher permissions.
Lastly I just want to say how funny it is that the top answer says quite the opposite of my answer and still both of us are right it's just how you interpret the question :-D. If you now say but you can't with the windows service project type - You CAN but I had this before and installation was sketchy and it was maybe kind of an unintentional hack until I found NSSM.
I think this is all you really need to do:
var listB = new List<int>{3, 4, 5};
var listA = new List<int>{1, 2, 3, 4, 5};
var listMerged = listA.Union(listB);

You should set async = false in head. Use post/get instead of ajax.
jQuery.ajaxSetup({ async: false });
$.post({
url: 'api.php',
data: 'id1=' + q + '',
dataType: 'json',
success: function (data) {
id = data[0];
vname = data[1];
}
});
I'd just like to add that one small issue with outputting the buffer strings from a spawned process with console.log()
is that it adds newlines, which can spread your spawned process output over additional lines. If you output stdout
or stderr
with process.stdout.write()
instead of console.log()
, then you'll get the console output from the spawned process 'as is'.
I saw that solution here: Node.js: printing to console without a trailing newline?
Hope that helps someone using the solution above (which is a great one for live output, even if it is from the documentation).
The answers above didn't help me solve my problem. After a long search I bumped into this partial solution.
I've finally solved my problem with this code to set the input field manually to ng-invalid (to set to ng-valid set it to 'true'):
$scope.myForm.inputName.$setValidity('required', false);
It appears that this behavior is supposedly changed in the latest beta, which at the time of writing is beta 6.
From the release notes for iOS 10 Beta 6:
WKWebView
now defaults to respectinguser-scalable=no
from a viewport. Clients ofWKWebView
can improve accessibility and allow users to pinch-to-zoom on all pages by setting theWKWebViewConfiguration
propertyignoresViewportScaleLimits
toYES
.
However, in my (very limited) testing, I can't yet confirm this to be the case.
Edit: verified, iOS 10 Beta 6 respects user-scalable=no
by default for me.
You can also do this

This also can happen just by having multiple supported frameworks defined in the app.config file and, forcing the app to run in a different .NET framework other than the one mentioned first in the app.config file.
And also this fires when you have both of the mentioned frameworks available in your system.
As a workaround, bring up the target framework you are going to use for the debugging up in the app.config
ex: if you trying to run in .NET 4, config file should have something similar to this,
<supportedRuntime version="v4.0"/>
<supportedRuntime version="v2.0.50727"/>

No, you can't get it quite like background-size:cover
but..
This approach is pretty damn close: it uses JavaScript to determine if the image is landscape or portrait, and applies styles accordingly.
JS
$('.myImages img').load(function(){
var height = $(this).height();
var width = $(this).width();
console.log('widthandheight:',width,height);
if(width>height){
$(this).addClass('wide-img');
}else{
$(this).addClass('tall-img');
}
});
CSS
.tall-img{
margin-top:-50%;
width:100%;
}
.wide-img{
margin-left:-50%;
height:100%;
}
@Bhabadyuti Bal give us a good answer, in gradle you can use :
compile 'org.springframework.boot:spring-boot-starter-data-jpa'
compile 'com.h2database:h2'
in test time :
testCompile 'org.reactivecommons.utils:object-mapper:0.1.0'
testCompile 'com.h2database:h2'
To run or debug tests in Visual Studio 2017, we need to install "NUnit3TestAdapter". We can install it in any version of Visual Studio, but it is working properly in the Visual Studio "community" version.
To install this, you can add it through the NuGet package.
There's a pause
command that does just that, though it's not specifically the enter key.
If you really want to wait for only the enter key, you can use the set
command to ask for user input with a dummy variable, something like:
set /p DUMMY=Hit ENTER to continue...
There is no my.cnf by default. As such, MySQL starts with all of the default settings. If you want to create your own my.cnf to override any defaults, place it at /etc/my.cnf.
Also, you can run mysql --help
and look through it for the conf locations listed.
Default options are read from the following files in the given order:
/etc/my.cnf /etc/mysql/my.cnf /usr/etc/my.cnf ~/.my.cnf
The following groups are read: mysql client
The following options may be given as the first argument:
--print-defaults Print the program argument list and exit.
--no-defaults Don't read default options from any option file.
--defaults-file=# Only read default options from the given file #.
--defaults-extra-file=# Read this file after the global files are read.
As you can see, there are also some options for bypassing the conf files, or specifying other files to read when you invoke mysql on the command line.

Misspellings are irritating, aren't they? Check your spelling of empty
, but then also try this:
#!/bin/bash -e
if [ -s diff.txt ]
then
rm -f empty.txt
touch full.txt
else
rm -f full.txt
touch empty.txt
fi
I like shell scripting a lot, but one disadvantage of it is that the shell cannot help you when you misspell, whereas a compiler like your C++ compiler can help you.
Notice incidentally that I have swapped the roles of empty.txt
and full.txt
, as @Matthias suggests.
if (File.Exists(fpath))
{
var data = File.ReadLines(fpath);
Console.WriteLine(data.ToArray()[14]);
}
If you're after readable fail messages, you can do without hamcrest by using the usual assertEquals with an empty list:
assertEquals(new ArrayList<>(0), yourList);
E.g. if you run
assertEquals(new ArrayList<>(0), Arrays.asList("foo", "bar");
you get
java.lang.AssertionError
Expected :[]
Actual :[foo, bar]
See http://api.jquery.com/jQuery.ajax/, there's mention of datatype and contentType there.
They are both used in the request to the server so the server knows what kind of data to receive/send.
Go to properties/launchSettings.json and find your appname and under this, find applicationUrl. you will see, it is running localhost:5000, change it to whatever you want. and then run dotnet run...... hurrah
Swift answer 2.
The UIWebView Class Reference advises against using webView.loadRequest(request):
Don’t use this method to load local HTML files; instead, use loadHTMLString:baseURL:.
In this solution, the html is read into a string. The html's url is used to work out the path, and passes that as a base url.
let url = bundle.URLForResource("index", withExtension: "html", subdirectory: "htmlFileFolder")
let html = try String(contentsOfURL: url)
let base = url.URLByDeletingLastPathComponent
webView.loadHTMLString(html, baseURL: base)

I have not used BeuatifulSoup but maybe the following can help in some tiny way.
import re
import urllib2
stuff = urllib2.urlopen(your_url_goes_here).read() # stuff will contain the *entire* page
# Replace the string Python with your desired regex
results = re.findall('(Python)',stuff)
for i in results:
print i
I'm not suggesting this is a replacement but maybe you can glean some value in the concept until a direct answer comes along.
Maybe join
+split
:
>>> a=12345
>>> list(map(int,' '.join(str(a)).split()))
[1, 2, 3, 4, 5]
>>> [int(i) for i in ' '.join(str(a)).split()]
[1, 2, 3, 4, 5]
>>>
str.join
+ str.split
is your friend, also we use map
or list comprehension
to get a list, (split what we join :-)).
You could use e.g. r.nextInt(101)
For a more generic "in between two numbers" use:
Random r = new Random();
int low = 10;
int high = 100;
int result = r.nextInt(high-low) + low;
This gives you a random number in between 10 (inclusive) and 100 (exclusive)

This is a late answer. Starting from SQLIte 3.24.0, released on June 4, 2018, there is finally a support for UPSERT clause following PostgreSQL syntax.
INSERT INTO players (user_name, age)
VALUES('steven', 32)
ON CONFLICT(user_name)
DO UPDATE SET age=excluded.age;
Note: For those having to use a version of SQLite earlier than 3.24.0, please reference this answer below (posted by me, @MarqueIV).
However if you do have the option to upgrade, you are strongly encouraged to do so as unlike my solution, the one posted here achieves the desired behavior in a single statement. Plus you get all the other features, improvements and bug fixes that usually come with a more recent release.
In this example, nothing really. The exact
param comes into play when you have multiple paths that have similar names:
For example, imagine we had a Users
component that displayed a list of users. We also have a CreateUser
component that is used to create users. The url for CreateUsers
should be nested under Users
. So our setup could look something like this:
<Switch>
<Route path="/users" component={Users} />
<Route path="/users/create" component={CreateUser} />
</Switch>
Now the problem here, when we go to http://app.com/users
the router will go through all of our defined routes and return the FIRST match it finds. So in this case, it would find the Users
route first and then return it. All good.
But, if we went to http://app.com/users/create
, it would again go through all of our defined routes and return the FIRST match it finds. React router does partial matching, so /users
partially matches /users/create
, so it would incorrectly return the Users
route again!
The exact
param disables the partial matching for a route and makes sure that it only returns the route if the path is an EXACT match to the current url.
So in this case, we should add exact
to our Users
route so that it will only match on /users
:
<Switch>
<Route exact path="/users" component={Users} />
<Route path="/users/create" component={CreateUser} />
</Switch>
A useful extension is to collect the results in a Dictionary
for fast lookup (e.g. in a loop):
var resultDict = _dbContext.Projects
.Where(p => p.Status == ProjectStatus.Active)
.GroupBy(f => f.Country)
.Select(g => new { country = g.Key, count = g.Count() })
.ToDictionary(k => k.country, i => i.count);

Swift 3: When you want to remove trailing string:
func replaceSuffix(_ suffix: String, replacement: String) -> String {
if hasSuffix(suffix) {
let sufsize = suffix.count < count ? -suffix.count : 0
let toIndex = index(endIndex, offsetBy: sufsize)
return substring(to: toIndex) + replacement
}
else
{
return self
}
}
.click()
does not work with Android (look at mozilla docs, at mobile section). You can trigger the click event with this method:
function fireClick(node){
if (document.createEvent) {
var evt = document.createEvent('MouseEvents');
evt.initEvent('click', true, false);
node.dispatchEvent(evt);
} else if (document.createEventObject) {
node.fireEvent('onclick') ;
} else if (typeof node.onclick == 'function') {
node.onclick();
}
}

I had same problem, but I think I have simple solution(code is from my RoR app): Extract industry ids from yahoo.finance.sectors and add it to db:
select = "select * from yahoo.finance.sectors"
generate_query select
@data.each do |data|
data["industry"].each do |ind|
unless ind.kind_of?(Array)
unless ind["id"].nil?
id = ind["id"].to_i
if id > 0
Industry.where(id: id).first_or_create(name: ind["name"]).update_attribute(:name, ind["name"])
end
end
end
end
end
Extract all comanies with their symbols with industry ids:
ids = Industry.all.map{|ind| "'#{ind.id.to_s}'" }.join(",")
select = "select * from yahoo.finance.industry where id in"
generate_query select, ids
@data.each do |ts|
unless ts.kind_of?(Array) || ts["company"].nil?
if ts["company"].count == 2 && ts["company"].first[0] == "name"
t = ts["company"]
Ticket.find_or_create_by_symbol(symbol: t["symbol"], name: t["name"] ).update_attribute(:name, t["name"])
else
ts["company"].each do |t|
Ticket.find_or_create_by_symbol(symbol: t["symbol"], name: t["name"] ).update_attribute(:name, t["name"])
end
end
end
end
end
Connection hellper:
def generate_query(select, ids = nil)
if params[:form] || params[:action] == "sectors" || params[:controller] == "tickets"
if params[:action] == "sectors" || params[:controller] == "tickets"
if ids.nil?
query= select
else
query= "#{select} (#{ids})"
end
else
if params[:form][:ids]
@conditions = params_parse params[:form][:ids]

Sorry for mess, but this is first testing version for my project and I needed it very fast. There are some helpers variabels and other things for my app, sorry for it. But I have question: Have many symbols do you have? I have 5500.
It's because you haven't declared outchar
before you use it. That means that the compiler will assume it's a function returning an int
and taking an undefined number of undefined arguments.
You need to add a prototype pf the function before you use it:
void outchar(char); /* Prototype (declaration) of a function to be called */ int main(void) { ... } void outchar(char ch) { ... }
Note the declaration of the main
function differs from your code as well. It's actually a part of the official C specification, it must return an int
and must take either a void
argument or an int
and a char**
argument.
Mac OS: On Terminal:
vim <your jar location>
after jar gets opened, press / and pass your class name and hit enter
Works the best. If you want to use it sitewide, without having to add this syntax to every class or ID, add the following CSS to your css body:
body {
-webkit-font-smoothing: antialiased;
text-shadow: 1px 1px 1px rgba(0,0,0,0.004);
background: url('./images/background.png');
text-align: left;
margin: auto;
}
We can do like below:
const item= {
image: require("../../assets/dashboard/project1.jpeg"),
location: "Chennai",
status: 1,
projectId: 1
}
<Image source={item.image} style={[{ width: 150, height: 150}]} />
sudo chown -R yourname:www-data cake
then
sudo chmod -R g+s cake
First command changes owner and group.
Second command adds s attribute which will keep new files and directories within cake having the same group permissions.
No formulas required. This works on as many columns as you need, but will only compare columns in the same worksheet:
NOTE: remove any duplicates from the individual columns first!
Duplicates are now highlighted in red
[Tested in Pre-lollipop as well as in Lollipop and above]
You can get your HTML string from the backend or from your resources files.
If you put your text as an resource string, make sure to add the CDATA
tag:
<string name="your_text">![CDATA[...<a href="your_link">Link Title</a> ...]]</string>
Then in code you need to get the string and assign it as HTML and set a link movement method:
String yourText = getString(R.string.your_text);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
textView.setText(Html.fromHtml(yourText, Html.FROM_HTML_MODE_COMPACT));
} else {
textView.setText(Html.fromHtml(yourText));
}
try {
subtext.setMovementMethod(LinkMovementMethod.getInstance());
} catch (Exception e) {
//This code seems to crash in some Samsung devices.
//You can handle this edge case base on your needs.
}

You need to find what your local network's IP of that computer is. Then other people can access to your site by that IP.
You can find your local network's IP by go to Command Prompt or press Windows + R then type in ipconfig
. It will give out some information and your local IP should look like 192.168.1.x.
Since you've already received help on the query, I'll take a poke at your syntax question:
The first query employs some lesser-known ANSI SQL syntax which allows you to nest joins between the join
and on
clauses. This allows you to scope/tier your joins and probably opens up a host of other evil, arcane things.
Now, while a nested join cannot refer any higher in the join hierarchy than its immediate parent, joins above it or outside of its branch can refer to it... which is precisely what this ugly little guy is doing:
select
count(*)
from Table1 as t1
join Table2 as t2
join Table3 as t3
on t2.Key = t3.Key -- join #1
and t2.Key2 = t3.Key2
on t1.DifferentKey = t3.DifferentKey -- join #2
This looks a little confusing because join #2 is joining t1 to t2 without specifically referencing t2... however, it references t2 indirectly via t3 -as t3 is joined to t2 in join #1. While that may work, you may find the following a bit more (visually) linear and appealing:
select
count(*)
from Table1 as t1
join Table3 as t3
join Table2 as t2
on t2.Key = t3.Key -- join #1
and t2.Key2 = t3.Key2
on t1.DifferentKey = t3.DifferentKey -- join #2
Personally, I've found that nesting in this fashion keeps my statements tidy by outlining each tier of the relationship hierarchy. As a side note, you don't need to specify inner. join is implicitly inner unless explicitly marked otherwise.
You can also supply the log-opts parameters on the docker run
command line, like this:
docker run --log-opt max-size=10m --log-opt max-file=5 my-app:latest
or in a docker-compose.yml like this
my-app:
image: my-app:latest
logging:
driver: "json-file"
options:
max-file: "5"
max-size: 10m

System.out.println(result/count)
you can't do this because result/count is not a String type, and System.out.println() only takes a String parameter. perhaps try:
double avg = (double)result / (double)args.length
If you prefer the diff output style from git diff
, you can use it with the --no-index
flag to compare files not in a git repository:
git diff --no-index a.txt b.txt
Using a couple of files with around 200k file name strings in each, I benchmarked (with the built-in time
command) this approach vs some of the other answers here:
git diff --no-index a.txt b.txt
# ~1.2s
comm -23 <(sort a.txt) <(sort b.txt)
# ~0.2s
diff a.txt b.txt
# ~2.6s
sdiff a.txt b.txt
# ~2.7s
vimdiff a.txt b.txt
# ~3.2s
comm
seems to be the fastest by far, while git diff --no-index
appears to be the fastest approach for diff-style output.
Update 2018-03-25 You can actually omit the --no-index
flag unless you are inside a git repository and want to compare untracked files within that repository. From the man pages:
This form is to compare the given two paths on the filesystem. You can omit the --no-index option when running the command in a working tree controlled by Git and at least one of the paths points outside the working tree, or when running the command outside a working tree controlled by Git.
this will work for all sort of youtube url :
if url could be
youtube.com/?v=_RCIP6OrQrE
youtube.com/v/_RCIP6OrQrE
youtube.com/watch?v=_RCIP6OrQrE
youtube.com/watch?v=_RCIP6OrQrE&feature=whatever&this=that
Pattern p = Pattern.compile("http.*\\?v=([a-zA-Z0-9_\\-]+)(?:&.)*");
String url = "http://www.youtube.com/watch?v=_RCIP6OrQrE";
Matcher m = p.matcher(url.trim()); //trim to remove leading and trailing space if any
if (m.matches()) {
url = m.group(1);
}
System.out.println(url);
this will extract video id from your url
