ALTER TABLE test1 ADD COLUMN id SERIAL PRIMARY KEY;

This is all you need to:

1. Add the id column
2. Populate it with a sequence from 1 to count(*).
3. Set it as primary key / not null.

Credit is given to @resnyanskiy who gave this answer in a comment.

PRIMARY KEY (id, name) didn't work for me. Adding a constraint did the job instead.

CREATE TABLE IF NOT EXISTS customer (
    id INTEGER, name TEXT,
    user INTEGER,
    CONSTRAINT PK_CUSTOMER PRIMARY KEY (user, id)
)

To prevent inserting a record that exist already. I'd check if the ID value exists in the database. For the example of a Table created with an IDENTITY PRIMARY KEY:

CREATE TABLE [dbo].[Persons] (    
    ID INT IDENTITY(1,1) PRIMARY KEY,
    LastName VARCHAR(40) NOT NULL,
    FirstName VARCHAR(40)
);

When JANE DOE and JOE BROWN already exist in the database.

SET IDENTITY_INSERT [dbo].[Persons] OFF;
INSERT INTO [dbo].[Persons] (FirstName,LastName)
VALUES ('JANE','DOE'); 
INSERT INTO Persons (FirstName,LastName) 
VALUES ('JOE','BROWN');

DATABASE OUTPUT of TABLE [dbo].[Persons] will be:

ID    LastName   FirstName
1     DOE        Jane
2     BROWN      JOE

I'd check if i should update an existing record or insert a new one. As the following JAVA example:

int NewID = 1;
boolean IdAlreadyExist = false;
// Using SQL database connection
// STEP 1: Set property
System.setProperty("java.net.preferIPv4Stack", "true");
// STEP 2: Register JDBC driver
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
// STEP 3: Open a connection
try (Connection conn1 = DriverManager.getConnection(DB_URL, USER,pwd) {
    conn1.setAutoCommit(true);
    String Select = "select * from Persons where  ID = " + ID;
    Statement st1 = conn1.createStatement();
    ResultSet rs1 = st1.executeQuery(Select);
    // iterate through the java resultset
    while (rs1.next()) {
        int ID = rs1.getInt("ID");
        if (NewID==ID) {
            IdAlreadyExist = true;
        }

    }
    conn1.close();
} catch (SQLException e1) {
    System.out.println(e1);
}
if (IdAlreadyExist==false) {
    //Insert new record code here
} else {
    //Update existing record code here
}

Primary key does not allow NULL values, but unique key allows NULL values.

We can declare only one primary key in a table, but a table can have multiple unique keys (column assign).

Due to the above mentioned problems, I prefer table value functions.

If you have this:

CREATE VIEW [dbo].[MyView] AS SELECT A, B FROM dbo.Something

create this:

CREATE FUNCTION MyFunction() RETURNS TABLE AS RETURN (SELECT * FROM [dbo].[MyView])

Then you simply import the function rather than the view.

Most Probably when you have a missing Primary key is not defined from parent table. then It occurs.

Like Add the primary key define in parent as below:

ALTER TABLE "FE_PRODUCT" ADD CONSTRAINT "FE_PRODUCT_PK" PRIMARY KEY ("ID") ENABLE;

Hope this will work.

CREATE  TABLE `mom`.`sec_subsection` (

  `idsec_sub` INT(11) NOT NULL ,

  `idSubSections` INT(11) NOT NULL ,

  PRIMARY KEY (`idsec_sub`, `idSubSections`) 

);

You will need to drop and re-create the primary key like this:

alter table my_table drop constraint my_pk;
alter table my_table add constraint my_pk primary key (city_id, buildtime, time);

However, if there are other tables with foreign keys that reference this primary key, then you will need to drop those first, do the above, and then re-create the foreign keys with the new column list.

An alternative syntax to drop the existing primary key (e.g. if you don't know the constraint name):

alter table my_table drop primary key;

As long as you have unique integers (or some unique value) in the current PK, you could create a new table, and insert into it with IDENTITY INSERT ON. Then drop the old table, and rename the new table.

Don't forget to recreate any indexes.

Primary key attributes are just as updateable as any other attributes of a table. Stability is often a desirable property of a key but definitely not an absolute requirement. If it makes sense from a business perpective to update a key then there's no fundamental reason why you shouldn't.

create table Table1
(
  id varchar(2),
  name varchar(2),
  PRIMARY KEY (id)
)


Create table Table1_Addr
(
  addid varchar(2),
  Address varchar(2),
  PRIMARY KEY (addid)
)

Create table Table1_sal
(
  salid varchar(2),`enter code here`
  addid varchar(2),
  id varchar(2),
  PRIMARY KEY (salid),
  index(addid),
  index(id),
  FOREIGN KEY (addid) REFERENCES Table1_Addr(addid),
  FOREIGN KEY (id) REFERENCES Table1(id)
)

A Table can have a Composite Primary Key which is a primary key made from two or more columns. For example:

CREATE TABLE userdata (
  userid INT,
  userdataid INT,
  info char(200),
  primary key (userid, userdataid)
);

Update: Here is a link with a more detailed description of composite primary keys.

You use a compound key (a key with more than one attribute) whenever you want to ensure the uniqueness of a combination of several attributes. A single attribute key would not achieve the same thing.

It is generally considered bad practise to have a one to one relationship. This is because you could just have the data represented in one table and achieve the same result.

However, there are instances where you may not be able to make these changes to the table you are referencing. In this instance there is no problem using the Foreign key as the primary key. It might help to have a composite key consisting of an auto incrementing unique primary key and the foreign key.

I am currently working on a system where users can log in and generate a registration code to use with an app. For reasons I won't go into I am unable to simply add the columns required to the users table. So I am going down a one to one route with the codes table.

"if you restore the primary key, you sure may revert it back to AUTO_INCREMENT"

There should be no question of whether or not it is desirable to "restore the PK property" and "restore the autoincrement property" of the ID column.

Given that it WAS an autoincrement in the prior definition of the table, it is quite likely that there exists some program that inserts into this table without providing an ID value (because the ID column is autoincrement anyway).

Any such program's operation will break by not restoring the autoincrement property.

I was facing the same problem so what I did I dropped the field for the primary key then I recreated it and made sure that it is auto incremental . That worked for me . I hope it helps others

It depends on the specific use case.

If your table is static and only has a short list of values (and there is just a small chance that this would change during a lifetime of DB), I would recommend this construction:

CREATE TABLE Foo 
(
    FooCode VARCHAR(16), -- short code or shortcut, but with some meaning.
    Name NVARCHAR(128), -- full name of entity, can be used as fallback in case when your localization for some language doesn't exist
    LocalizationCode AS ('Foo.' + FooCode) -- This could be a code for your localization table... 
)

Of course, when your table is not static at all, using INT as primary key is the best solution.

Solution:

INSERT INTO `table` (`value1`, `value2`) 
SELECT 'stuff for value1', 'stuff for value2' FROM DUAL 
WHERE NOT EXISTS (SELECT * FROM `table` 
      WHERE `value1`='stuff for value1' AND `value2`='stuff for value2' LIMIT 1) 

Explanation:

The innermost query

SELECT * FROM `table` 
      WHERE `value1`='stuff for value1' AND `value2`='stuff for value2' LIMIT 1

used as the WHERE NOT EXISTS-condition detects if there already exists a row with the data to be inserted. After one row of this kind is found, the query may stop, hence the LIMIT 1 (micro-optimization, may be omitted).

The intermediate query

SELECT 'stuff for value1', 'stuff for value2' FROM DUAL

represents the values to be inserted. DUAL refers to a special one row, one column table present by default in all Oracle databases (see https://en.wikipedia.org/wiki/DUAL_table). On a MySQL-Server version 5.7.26 I got a valid query when omitting FROM DUAL, but older versions (like 5.5.60) seem to require the FROM information. By using WHERE NOT EXISTS the intermediate query returns an empty result set if the innermost query found matching data.

The outer query

INSERT INTO `table` (`value1`, `value2`) 

inserts the data, if any is returned by the intermediate query.

it simple, select columns want to insert primary key and click on Key icon on header and save table

happy coding..,

You cannot create a primary key on a view. In SQL Server you can create an index on a view but that is different to creating a primary key.

If you give us more information as to why you want a key on your view, perhaps we can help with that.

MySQL unique and primary keys serve to identify rows. There can be only one Primary key in a table but one or more unique keys. Key is just index.

for more details you can check http://www.geeksww.com/tutorials/database_management_systems/mysql/tips_and_tricks/mysql_primary_key_vs_unique_key_constraints.php

to convert mysql to mssql try this and see http://gathadams.com/2008/02/07/convert-mysql-to-ms-sql-server/

You can use the IGNORE keyword too, example:

 update IGNORE table set primary_field = 'value'...............

In my case the error was very misleading. The problem was that PHPMyAdmin uses "ALTER TABLE" when you click on the "make unique" button instead of "ALTER IGNORE TABLE", so I had to do it manually, like in:

ALTER TABLE mytbl ADD UNIQUE (columnName);

This link says it better than I could and helped in my decision making. I usually opt for an int as a primary key, unless I have a specific need not to and I also let SQL server auto-generate/maintain this field unless I have some specific reason not to. In reality, performance concerns need to be determined based on your specific app. There are many factors at play here including but not limited to expected db size, proper indexing, efficient querying, and more. Although people may disagree, I think in many scenarios you will not notice a difference with either option and you should choose what is more appropriate for your app and what allows you to develop easier, quicker, and more effectively (If you never complete the app what difference does the rest make :).

P.S. I'm not sure why you would use a Composite PK or what benefit you believe that would give you.

CREATE TABLE `voting` (
  `QuestionID` int(10) unsigned NOT NULL,
  `MemberId` int(10) unsigned NOT NULL,
  `vote` int(10) unsigned NOT NULL,
  PRIMARY KEY  (`QuestionID`,`MemberId`)
);

Identified this solution while reading this thread. Figured id post this for the next guy possibly.

When dealing with Laravel migration file from a package, I Ran into this issue.

My old value was

$table->increments('id');

My new

$table->integer('id')->autoIncrement();

Another issue with using Strings as a primary key is that because the index is constantly put into sequential order, when a new key is created that would be in the middle of the order the index has to be resequenced... if you use an auto number integer, the new key is just added to the end of the index.

If you add primary key constraint

ALTER TABLE <TABLE NAME> ADD CONSTRAINT <CONSTRAINT NAME> PRIMARY KEY <COLUMNNAME>  

for example:

ALTER TABLE DEPT ADD CONSTRAINT PK_DEPT PRIMARY KEY (DEPTNO)

A well-explained answer is already given by @mkobit, but I will add a big picture of the range key and hash key.

In a simple words range + hash key = composite primary key CoreComponents of Dynamodb

A primary key is consists of a hash key and an optional range key. Hash key is used to select the DynamoDB partition. Partitions are parts of the table data. Range keys are used to sort the items in the partition, if they exist.

So both have a different purpose and together help to do complex query. In the above example hashkey1 can have multiple n-range. Another example of range and hashkey is game, userA(hashkey) can play Ngame(range)

The Music table described in Tables, Items, and Attributes is an example of a table with a composite primary key (Artist and SongTitle). You can access any item in the Music table directly, if you provide the Artist and SongTitle values for that item.

A composite primary key gives you additional flexibility when querying data. For example, if you provide only the value for Artist, DynamoDB retrieves all of the songs by that artist. To retrieve only a subset of songs by a particular artist, you can provide a value for Artist along with a range of values for SongTitle.

If your table has relationship with other tables using its primary or foriegen key, may be it is impossible to alter your table. so you need to drop and create the table again.
To solve these problems you need to Generate Scripts by right click on the database and in advanced option set type of data to script to scheme and data. after that, using this script with the changing your column to identify and regenerate the table using run its query.
your query will be like here:

USE [Db_YourDbName]
GO
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
Drop TABLE [dbo].[Tbl_TourTable]

CREATE TABLE [dbo].[Tbl_TourTable](
    [ID] [int] IDENTITY(1,1) NOT NULL,
    [Name] [nvarchar](50) NULL,
    [Family] [nvarchar](150) NULL)  

GO

SET IDENTITY_INSERT [dbo].[Tbl_TourTable] ON 

INSERT [dbo].[Tbl_TourTable] ([ID], [Name], [Family]) VALUES (1,'name 1', 'family 1')
INSERT [dbo].[Tbl_TourTable] ([ID], [Name], [Family]) VALUES (1,'name 1', 'family 1')
INSERT [dbo].[Tbl_TourTable] ([ID], [Name], [Family]) VALUES (1,'name 1', 'family 1')
INSERT [dbo].[Tbl_TourTable] ([ID], [Name], [Family]) VALUES (1,'name 1', 'family 1')
INSERT [dbo].[Tbl_TourTable] ([ID], [Name], [Family]) VALUES (1,'name 1', 'family 1')
INSERT [dbo].[Tbl_TourTable] ([ID], [Name], [Family]) VALUES (1,'name 1', 'family 1')
INSERT [dbo].[Tbl_TourTable] ([ID], [Name], [Family]) VALUES (1,'name 1', 'family 1')

SET IDENTITY_INSERT [dbo].[Tbl_TourTable] off 

You should use PRIMARY from key_column_usage.constraint_name = "PRIMARY"

sample query,

SELECT k.column_name as PK, concat(tbl.TABLE_SCHEMA, '.`', tbl.TABLE_NAME, '`') as TABLE_NAME
FROM information_schema.TABLES tbl
JOIN information_schema.key_column_usage k on k.table_name = tbl.table_name
WHERE k.constraint_name='PRIMARY'
  AND tbl.table_schema='MYDB'
  AND tbl.table_type="BASE TABLE";

This is the perfect kind of field to define as CHAR 36, by the way, not VARCHAR 36, since each value will have the exact same length. And you'll use less storage space, since you don't need to store the data length for each value, just the value.

alter table table_name
add constraint myprimarykey primary key(column);

These two procedures let me reset the sequence and reset the sequence based on data in a table (apologies for the coding conventions used by this client):

CREATE OR REPLACE PROCEDURE SET_SEQ_TO(p_name IN VARCHAR2, p_val IN NUMBER)
AS
   l_num   NUMBER;
BEGIN
   EXECUTE IMMEDIATE 'select ' || p_name || '.nextval from dual' INTO l_num;

   -- Added check for 0 to avoid "ORA-04002: INCREMENT must be a non-zero integer"
   IF (p_val - l_num - 1) != 0
   THEN
      EXECUTE IMMEDIATE 'alter sequence ' || p_name || ' increment by ' || (p_val - l_num - 1) || ' minvalue 0';
   END IF;

   EXECUTE IMMEDIATE 'select ' || p_name || '.nextval from dual' INTO l_num;

   EXECUTE IMMEDIATE 'alter sequence ' || p_name || ' increment by 1 ';

   DBMS_OUTPUT.put_line('Sequence ' || p_name || ' is now at ' || p_val);
END;

CREATE OR REPLACE PROCEDURE SET_SEQ_TO_DATA(seq_name IN VARCHAR2, table_name IN VARCHAR2, col_name IN VARCHAR2)
AS
   nextnum   NUMBER;
BEGIN
   EXECUTE IMMEDIATE 'SELECT MAX(' || col_name || ') + 1 AS n FROM ' || table_name INTO nextnum;

   SET_SEQ_TO(seq_name, nextnum);
END;

Absolutely not.

I have done several... several... performance checks between INT, VARCHAR, and CHAR.

10 million record table with a PRIMARY KEY (unique and clustered) had the exact same speed and performance (and subtree cost) no matter which of the three I used.

That being said... use whatever is best for your application. Don't worry about the performance.

According to Android Sqlite get last insert row id there is another query:

SELECT rowid from your_table_name order by ROWID DESC limit 1

ALTER TABLE foo AUTO_INCREMENT=1

If you've deleted the most recent entries, that should set it to use the next lowest available one. As in, as long as there's no 19 already, deleting 16-18 will reset the autoincrement to use 16.

EDIT: I missed the bit about phpmyadmin. You can set it there, too. Go to the table screen, and click the operations tab. There's an AUTOINCREMENT field there that you can set to whatever you need manually.

I had this issue come up and believe it was caused because I had deleted the Index on my tables primary key and replaced it with an index on some of the other fields in the table.

After I deleted the primary key index and refreshed the edmx, inserts stopped working.

I refreshed the table to the older version, refreshed the edmx and everything works again.

I should note that when I opened the EDMX to troubleshoot this issue, checking to see if there was a primary key defined, there was. So none of the above suggestions were helping me. But refreshing the index on the primary key seemed to work.

primary keys are automatically indexed

you can create additional indices using the pk depending on your usage

• index zip_code, id may be helpful if you often select by zip_code and id

You don't need to create the table first and then add the keys in subsequent steps. You can add both primary key and foreign key while creating the table:

This example assumes the existence of a table (Codes) that we would want to reference with our foreign key.

CREATE TABLE d (
id [numeric](1),
code [varchar](2),
PRIMARY KEY (id, code),
CONSTRAINT fk_d_codes FOREIGN KEY (code) REFERENCES Codes (code)
)

If you don't have a table that we can reference, add one like this so that the example will work:

CREATE TABLE Codes (
    Code [varchar](2) PRIMARY KEY   
    )

NOTE: you must have a table to reference before creating the foreign key.

Simply Primary Key is a unique and can't be null, unique can be null and may not be unique.

For example, like this:

const querystring = require('querystring');
const https = require('https');

var postData = querystring.stringify({
    'msg' : 'Hello World!'
});

var options = {
  hostname: 'posttestserver.com',
  port: 443,
  path: '/post.php',
  method: 'POST',
  headers: {
       'Content-Type': 'application/x-www-form-urlencoded',
       'Content-Length': postData.length
     }
};

var req = https.request(options, (res) => {
  console.log('statusCode:', res.statusCode);
  console.log('headers:', res.headers);

  res.on('data', (d) => {
    process.stdout.write(d);
  });
});

req.on('error', (e) => {
  console.error(e);
});

req.write(postData);
req.end();

There are lots of options out there. Many of which are available as downloadable software as well as public websites. I do not think many of them expect to be used as API's unless they explicitly state that.

The one that I found effective was Enju which did not have the character limit that the Marc's Carnagie Mellon link had. Marc also mentioned a VISL scanner in comments, but that requires java in the browser, which is a non-starter for me.

Note that recently, Google has offered a new NLP Machine Learning API that providers amoung other features, a automatic sentence parser. I will likely not update this answer again, especially since the question is closed, but I suspect that the other big ML cloud stacks will soon support the same.

How to specify the JDK version?

Use any of three ways: (1) Spring Boot feature, or use Maven compiler plugin with either (2) source & target or (3) with release.

Spring Boot

1. <java.version> is not referenced in the Maven documentation.
   It is a Spring Boot specificity.
   It allows to set the source and the target java version with the same version such as this one to specify java 1.8 for both :

   1.8

Feel free to use it if you use Spring Boot.

maven-compiler-plugin with source & target

2. Using maven-compiler-plugin or maven.compiler.source/maven.compiler.target properties are equivalent.

That is indeed :

<plugins>
    <plugin>    
        <artifactId>maven-compiler-plugin</artifactId>
        <configuration>
            <source>1.8</source>
            <target>1.8</target>
        </configuration>
    </plugin>
</plugins>

is equivalent to :

<properties>
    <maven.compiler.source>1.8</maven.compiler.source>
    <maven.compiler.target>1.8</maven.compiler.target>
</properties>

according to the Maven documentation of the compiler plugin since the <source> and the <target> elements in the compiler configuration use the properties maven.compiler.source and maven.compiler.target if they are defined.

source

The -source argument for the Java compiler.
Default value is: 1.6.
User property is: maven.compiler.source.

target

The -target argument for the Java compiler.
Default value is: 1.6.
User property is: maven.compiler.target.

About the default values for source and target, note that since the 3.8.0 of the maven compiler, the default values have changed from 1.5 to 1.6.

maven-compiler-plugin with release instead of source & target

3. The maven-compiler-plugin 3.6 and later versions provide a new way :

   org.apache.maven.plugins maven-compiler-plugin 3.8.0 9

You could also declare just :

<properties>
    <maven.compiler.release>9</maven.compiler.release>
</properties>

But at this time it will not work as the maven-compiler-plugin default version you use doesn't rely on a recent enough version.

The Maven release argument conveys release : a new JVM standard option that we could pass from Java 9 :

Compiles against the public, supported and documented API for a specific VM version.

This way provides a standard way to specify the same version for the source, the target and the bootstrap JVM options.
Note that specifying the bootstrap is a good practice for cross compilations and it will not hurt if you don't make cross compilations either.

Which is the best way to specify the JDK version?

The first way (<java.version>) is allowed only if you use Spring Boot.

For Java 8 and below :

About the two other ways : valuing the maven.compiler.source/maven.compiler.target properties or using the maven-compiler-plugin, you can use one or the other. It changes nothing in the facts since finally the two solutions rely on the same properties and the same mechanism : the maven core compiler plugin.

Well, if you don't need to specify other properties or behavior than Java versions in the compiler plugin, using this way makes more sense as this is more concise:

<properties>
    <maven.compiler.source>1.8</maven.compiler.source>
    <maven.compiler.target>1.8</maven.compiler.target>
</properties>

From Java 9 :

The release argument (third point) is a way to strongly consider if you want to use the same version for the source and the target.

What happens if the version differs between the JDK in JAVA_HOME and which one specified in the pom.xml?

It is not a problem if the JDK referenced by the JAVA_HOME is compatible with the version specified in the pom but to ensure a better cross-compilation compatibility think about adding the bootstrap JVM option with as value the path of the rt.jar of the target version.

An important thing to consider is that the source and the target version in the Maven configuration should not be superior to the JDK version referenced by the JAVA_HOME.
A older version of the JDK cannot compile with a more recent version since it doesn't know its specification.

To get information about the source, target and release supported versions according to the used JDK, please refer to java compilation : source, target and release supported versions.

How handle the case of JDK referenced by the JAVA_HOME is not compatible with the java target and/or source versions specified in the pom?

For example, if your JAVA_HOME refers to a JDK 1.7 and you specify a JDK 1.8 as source and target in the compiler configuration of your pom.xml, it will be a problem because as explained, the JDK 1.7 doesn't know how to compile with.
From its point of view, it is an unknown JDK version since it was released after it.
In this case, you should configure the Maven compiler plugin to specify the JDK in this way :

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <configuration>
        <source>1.8</source>
        <target>1.8</target>
        <compilerVersion>1.8</compilerVersion>      
        <fork>true</fork>
        <executable>D:\jdk1.8\bin\javac</executable>                
    </configuration>
</plugin>

You could have more details in examples with maven compiler plugin.

It is not asked but cases where that may be more complicated is when you specify source but not target. It may use a different version in target according to the source version. Rules are particular : you can read about them in the Cross-Compilation Options part.

Why the compiler plugin is traced in the output at the execution of the Maven package goal even if you don't specify it in the pom.xml?

To compile your code and more generally to perform all tasks required for a maven goal, Maven needs tools. So, it uses core Maven plugins (you recognize a core Maven plugin by its groupId : org.apache.maven.plugins) to do the required tasks : compiler plugin for compiling classes, test plugin for executing tests, and so for... So, even if you don't declare these plugins, they are bound to the execution of the Maven lifecycle.
At the root dir of your Maven project, you can run the command : mvn help:effective-pom to get the final pom effectively used. You could see among other information, attached plugins by Maven (specified or not in your pom.xml), with the used version, their configuration and the executed goals for each phase of the lifecycle.

In the output of the mvn help:effective-pom command, you could see the declaration of these core plugins in the <build><plugins> element, for example :

...
<plugin>
   <artifactId>maven-clean-plugin</artifactId>
   <version>2.5</version>
   <executions>
     <execution>
       <id>default-clean</id>
       <phase>clean</phase>
       <goals>
         <goal>clean</goal>
       </goals>
     </execution>
   </executions>
 </plugin>
 <plugin>
   <artifactId>maven-resources-plugin</artifactId>
   <version>2.6</version>
   <executions>
     <execution>
       <id>default-testResources</id>
       <phase>process-test-resources</phase>
       <goals>
         <goal>testResources</goal>
       </goals>
     </execution>
     <execution>
       <id>default-resources</id>
       <phase>process-resources</phase>
       <goals>
         <goal>resources</goal>
       </goals>
     </execution>
   </executions>
 </plugin>
 <plugin>
   <artifactId>maven-compiler-plugin</artifactId>
   <version>3.1</version>
   <executions>
     <execution>
       <id>default-compile</id>
       <phase>compile</phase>
       <goals>
         <goal>compile</goal>
       </goals>
     </execution>
     <execution>
       <id>default-testCompile</id>
       <phase>test-compile</phase>
       <goals>
         <goal>testCompile</goal>
       </goals>
     </execution>
   </executions>
 </plugin>
  ...

You can have more information about it in the introduction of the Maven lifeycle in the Maven documentation.

Nevertheless, you can declare these plugins when you want to configure them with other values as default values (for example, you did it when you declared the maven-compiler plugin in your pom.xml to adjust the JDK version to use) or when you want to add some plugin executions not used by default in the Maven lifecycle.

Does the column allow null?

Seems to work. Just tested with phpMyAdmin, the column is of type int that allows nulls:

INSERT INTO `database`.`table` (`column`) VALUES (NULL);

LINUX

struct timeval tv;
tv.tv_sec = 30;        // 30 Secs Timeout
tv.tv_usec = 0;        // Not init'ing this can cause strange errors
setsockopt(sockfd, SOL_SOCKET, SO_RCVTIMEO, (const char*)&tv,sizeof(struct timeval));

WINDOWS

DWORD timeout = SOCKET_READ_TIMEOUT_SEC * 1000;
setsockopt(socket, SOL_SOCKET, SO_RCVTIMEO, (const char*)&timeout, sizeof(timeout));

NOTE: You have put this setting before bind() function call for proper run

Just iterate and add:

for(Map.Entry e : a.entrySet())
  if(!b.containsKey(e.getKey())
    b.put(e.getKey(), e.getValue());

Edit to add:

If you can make changes to a, you can also do:

a.putAll(b)

and a will have exactly what you need. (all the entries in b and all the entries in a that aren't in b)

adb remount

works for me and seems to be the simplest solution.

You simply have to pipe an iconv command before the sed command. Ex with file.txt input :

iconv -f ISO-8859-1 -t UTF8-MAC file.txt | sed 's/something/àéèêçùû/g' | .....

-f option is the 'from' codeset and -t option is the 'to' codeset conversion.

Take care of case, web pages usually show lowercase like that < charset=iso-8859-1"/> and iconv uses uppercase. You have list of iconv supported codesets in you system with command iconv -l

UTF8-MAC is modern OS Mac codeset for conversion.

I would suggest you to don't modify web.config from your, because every time when change, it will restart your application.

However you can read web.config using System.Configuration.ConfigurationManager.AppSettings

You need to provide the name of a branch (or other commit identifier), not the name of a remote to git rebase.

E.g.:

git rebase origin/master

not:

git rebase origin

Note, although origin should resolve to the the ref origin/HEAD when used as an argument where a commit reference is required, it seems that not every repository gains such a reference so it may not (and in your case doesn't) work. It pays to be explicit.

Some of this seems "incomplete"

Groups of people are NOT going to know if they should use quotes etc..

Add 1 specific file showing the location paths as well

git add JobManager/Controllers/APIs/ProfileApiController.cs

Commit (remember, commit is local only, it is not affecting any other system)

git commit -m "your message"  

Push to remote repo

git push  (this is after the commit and this attempts to Merge INTO the remote location you have instructed it to merge into)

Other answer(s) show the stash etc. which you sometimes will want to do

Googling gives many sites... Debugging with the Eclipse platform for one.

[root]# cat time.c

#include <time.h>

int main(int argc, char** argv)
{
        time_t test;
        return 0;
}

[root]# gcc -E time.c | grep __time_t

typedef long int __time_t;

It's defined in $INCDIR/bits/types.h through:

# 131 "/usr/include/bits/types.h" 3 4
# 1 "/usr/include/bits/typesizes.h" 1 3 4
# 132 "/usr/include/bits/types.h" 2 3 4

As Maciej Jonczyk mentioned, you may also need to increase margins

par(las=2)
par(mar=c(8,8,1,1)) # adjust as needed
plot(...)

You can use VBSedit software to convert your VBS code to .exe file. You can download free version from Internet and installtion vbsedit applilcation on your system and convert the files to exe format.

Vbsedit is a good application for VBscripter's

You could use sed -n 5p file.

You can also get a range, e.g., sed -n 5,10p file.

This works for me - I finally figured a one liner

df <- as.data.frame(lapply(df,function (y) if(class(y)=="factor" ) as.character(y) else y),stringsAsFactors=F)

1. Firstly reset your password at "https://id.atlassian.com"
2. Ensure you are able to login to Bitbucket Cloud - "https://bitbucket.org"
3. Clear stored credentials on your machine a. Windows: Navigate to Credential Manager and clear stored credentials related to Bitbucket Cloud.
4. Mac OS X: Navigate to Keychain Access and clear stored credentials related to Bitbucket
5. Cloud Once this is done, try to login to perform a git operation authenticating to Bitbucket Cloud once again.

git stash is your friend.

If you have not made the commit yet, just run git stash. This will save away all of your changes.

Switch to the branch you want the changes on and run git stash pop.

There are lots of uses for git stash. This is certainly one of the more useful reasons.

An example:

# work on some code
git stash
git checkout correct-branch
git stash pop

Syntax:

  class Sample
  {
     public:
         int Sam_x;
         int Sam_y;

     Sample(): Sam_x(1), Sam_y(2)     /* Classname: Initialization List */
     {
           // Constructor body
     }
  };

Need of Initialization list:

 class Sample
 {
     public:
         int Sam_x;
         int Sam_y;

     Sample()     */* Object and variables are created - i.e.:declaration of variables */*
     { // Constructor body starts 

         Sam_x = 1;      */* Defining a value to the variable */* 
         Sam_y = 2;

     } // Constructor body ends
  };

in the above program, When the class’s constructor is executed, Sam_x and Sam_y are created. Then in constructor body, those member data variables are defined.

Use cases:

1. Const and Reference variables in a Class

In C, variables must be defined during creation. the same way in C++, we must initialize the Const and Reference variable during object creation by using Initialization list. if we do initialization after object creation (Inside constructor body), we will get compile time error.

2. Member objects of Sample1 (base) class which do not have default constructor

    class Sample1 
    {
        int i;
        public:
        Sample1 (int temp)
        {
           i = temp;
        }
    };
   
     // Class Sample2 contains object of Sample1 
    class Sample2
    {
     Sample1  a;
     public:
     Sample2 (int x): a(x)      /* Initializer list must be used */
     {
   
     }
    };
   

While creating object for derived class which will internally calls derived class constructor and calls base class constructor (default). if base class does not have default constructor, user will get compile time error. To avoid, we must have either

 1. Default constructor of Sample1 class
 2. Initialization list in Sample2 class which will call the parametric constructor of Sample1 class (as per above program)

3. Class constructor’s parameter name and Data member of a Class are same:

    class Sample3 {
       int i;         /* Member variable name : i */  
       public:
       Sample3 (int i)    /* Local variable name : i */ 
       {
           i = i;
           print(i);   /* Local variable: Prints the correct value which we passed in constructor */
       }
       int getI() const 
       { 
            print(i);    /*global variable: Garbage value is assigned to i. the expected value should be which we passed in constructor*/
            return i; 
       }
    };
   

As we all know, local variable having highest priority then global variable if both variables are having same name. In this case, the program consider "i" value {both left and right side variable. i.e: i = i} as local variable in Sample3() constructor and Class member variable(i) got override. To avoid, we must use either

  1. Initialization list 
  2. this operator.

All you need is the following:

\makeatletter
\def\sec#1{\def\tempa{#1}\futurelet\next\sec@i}% Save first argument
\def\sec@i{\ifx\next\bgroup\expandafter\sec@ii\else\expandafter\sec@end\fi}%Check brace
\def\sec@ii#1{\section*{\tempa\ and #1}}%Two args
\def\sec@end{\section*{\tempa}}%Single args
\makeatother

\sec{Hello}
%Output: Hello
\sec{Hello}{Hi}
%Output: Hello and Hi

I know this is kind of an old topic, but I would use the Powershell variable

$env:UserProfile 

To use it to get to the desktop, it would be:

cd $env:UserProfile\desktop

This works both locally and remotely on windows 7. Hope this is useful as I ran across a situation where a client machine didn't have a value in $home.

small remark: I am using modules in webbased application (asp.net). I need to remember that everything I store in the variables on the module are seen by everyone in the application, read website. Not only in my session. If i try to add up a calculation in my session I need to make an array to filter the numbers for my session and for others. Modules is a great way to work but need concentration on how to use it.

To help against mistakes: classes are send to the

CarbageCollector

when the page is finished. My modules stay alive (as long as the application is not ended or restarted) and I can reuse the data in it. I use this to save data that sometimes is lost because of the sessionhandling by IIS.

IIS Form auth

and

IIS_session

are not in sync, and with my module I pull back data that went over de cliff.

The code below filters filenames starting with given substring. It could be changed to fit different needs by working on subfname substring extraction and IF statement:

echo off
rem filter all files not starting with the prefix 'dat'
setlocal enabledelayedexpansion
FOR /R your-folder-fullpath %%F IN (*.*) DO (
set fname=%%~nF
set subfname=!fname:~0,3!
IF NOT "!subfname!" == "dat" echo "%%F"
)
pause

For everyone else who has no duplicate Listen directives and no running processes on the port: check that you don't accidentally include ports.conf twice in apache2.conf (as I did due to a bad merge).

To check on which environment your notebook is running type the following commands in the notebook shell

import sys
print(sys.executable)

To launch the notebook in a new environment deactivate that environment first. Create a conda environment and then install the ipykernel. Activate that environment. Install jupyter on that environment.

conda create --name {envname}
conda install ipykernel --name {envname}
python -m ipykernel install --prefix=C:/anaconda/envs/{envname} --name {envname}
activate envname
pip install jupyter

In your case path "C:/anaconda/envs/{envname}" could be different, check accordingly. After following all steps, launch notebook and do step 1 run the following in shell.

sys.executable

This should show: Anaconda/envs/envname

You can use a combination of Vuex actions, getters, computed properties and watchers to listen to changes on a Vuex state value.

HTML Code:

<div id="app" :style='style'>
  <input v-model='computedColor' type="text" placeholder='Background Color'>
</div>

JavaScript Code:

'use strict'

Vue.use(Vuex)

const { mapGetters, mapActions, Store } = Vuex

new Vue({
    el: '#app',
  store: new Store({
    state: {
      color: 'red'
    },
    getters: {
      color({color}) {
        return color
      }
    },
    mutations: {
      setColor(state, payload) {
        state.color = payload
      }
    },
    actions: {
      setColor({commit}, payload) {
        commit('setColor', payload)
      }
    }
  }),
  methods: {
    ...mapGetters([
        'color'
    ]),
    ...mapActions([
        'setColor'
    ])
  },
  computed: {
    computedColor: {
        set(value) {
        this.setColor(value)
      },
      get() {
        return this.color()
      }
    },
    style() {
        return `background-color: ${this.computedColor};`
    }
  },
  watch: {
    computedColor() {
        console.log(`Watcher in use @${new Date().getTime()}`)
    }
  }
})

See JSFiddle demo.

I played a bit with this problem and at this end I used this:

function getJsonFromUrl() {
  return Object.assign(...location.search.substr(1).split("&").map(sliceProperty));
}

• Object.assign to transform a list of object into one object
• Spread operator ... to transform an array into a list
• location.search.substr(1).split("&") to get all parameters as array of properties (foo=bar)
• map walk each properties and split them into an array (either call splitProperty or sliceProperty).

splitProperty:

  function splitProperty(pair) {
    [key, value] = pair.split("=")
    return { [key]: decodeURIComponent(value) }
  }

• Split by =
• Deconstruct the array into an array of two elements
• Return a new object with the dynamic property syntax

sliceProperty:

  function sliceProperty(pair) {
    const position = pair.indexOf("="),
      key = pair.slice(0, position),
      value = pair.slice(position + 1, pair.length);
    return { [key]: decodeURIComponent(value) }
  }

• Set the position of =, key and value
• Return a new object with the dynamic property syntax

I think splitProperty is prettier but sliceProperty is faster. Run JsPerf for more information.

<html>
<script>
var simpleText = "hello_world";
var finalSplitText = simpleText.split("_");
var splitText = finalSplitText[0];

window.onload = function() {
       //when the document is finished loading, replace everything
       //between the <a ...> </a> tags with the value of splitText
   document.getElementById("myLink").innerHTML=splitText;
} 

</script>

<body>
<a id="myLink" href = test.html></a>
</body>
</html>

You could use the static StartupPath property of the Application class.

<?php 
    $sessionDetails = $this->Session->read('Auth.User');

    if (!empty($sessionDetails)) {


        $loginFlag = 1;
        # code...
    }else{
        $loginFlag =  0;
    }


?>

<script type="text/javascript">

    var sessionValue = '<?php echo $loginFlag; ?>';
    if (sessionValue = 0) {

        //model show
    }
</script>

The git.exe from Github for windows is located in a path like C:\Users\<username>\AppData\Local\GitHub\PortableGit_<numbersandletters>\bin\git.exe1 You have to replace <username> and <numbersandletters> to the actual situation on your system.

In Android Studio you can specify the path to the Git executable at File->Settings...->Version Control->Git->Path to Git executable. Here you have to include the actual executable name. As an example, in my case the actual path is: C:\Users\dennis\AppData\Local\GitHub\PortableGit_69703d1db91577f4c666e767a6ca5ec50a48d243\bin\git.exe

Edit: Last git update has put the git.exe file in cmd\ folder instead of bin\ . so now the actual path will be as suggested in the comment below by al3xAndr3w.

C:\Users\<username>\AppData\Local\GitHub\PortableGit_<numbersandletters>\cmd\git.exe

There is an easy way to get Jobs' Owners info from multiple instances by PowerShell:

Run the script in your PowerShell ISE:

Loads SQL Powerhell SMO and commands:

Import-Module SQLPS -disablenamechecking

BUild list of Servers manually (this builds an array list):

$SQLServers = "SERVERNAME\INSTANCE01","SERVERNAME\INSTANCE02","SERVERNAME\INSTANCE03";
$SysAdmins = $null;
foreach($SQLSvr in $SQLServers)
{
    ## - Add Code block:
    $MySQL = new-object Microsoft.SqlServer.Management.Smo.Server $SQLSvr;
    DIR SQLSERVER:\SQL\$SQLSvr\JobServer\Jobs| FT $SQLSvr, NAME, OWNERLOGINNAME -Auto 
    ## - End of Code block
}

round does take negative ndigits parameter!

>>> round(46,-1)
50

may solve your case.

It's because your TextView recieve new text on every iteration and previuos value thrown away. Concatenate strings by StringBuilder and set TextView value after loop. Also you can use this type of loop:

for (Map.Entry<String, String> e : map.entrySet()) {
    //to get key
    e.getKey();
    //and to get value
    e.getValue();
}

You should re-assign the result of the replacement, like this:

 sentence = sentence.replace("and", " ");

Be aware that the String class is immutable, meaning that all of its methods return a new string and never modify the original string in-place, so the result of invoking a method in an instance of String must be assigned to a variable or used immediately for the change to take effect.

Just put some CSS into the stylesheet like this

form {
  text-align: center;
}

then you're done!

l = []
x = 0
l.extend([x]*100)

You can easily do this by:

::variableName.isInitialized

or

this::variableName.isInitialized

But if you are inside a listener or inner class, do this:

this@OuterClassName::variableName.isInitialized

Note: The above statements work fine if you are writing them in the same file(same class or inner class) where the variable is declared but this will not work if you want to check the variable of other class (which could be a superclass or any other class which is instantiated), for ex:

class Test {
    lateinit var str:String
}

And to check if str is initialized:

What we are doing here: checking isInitialized for field str of Test class in Test2 class. And we get an error backing field of var is not accessible at this point. Check a question already raised about this.

This example reads 6 bytes into a byte array and writes it to another byte array. It does an XOR operation with the bytes so that the result written to the file is the same as the original starting values. The file is always 6 bytes in size, since it writes at position 0.

using System;
using System.IO;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main()
        {
        byte[] b1 = { 1, 2, 4, 8, 16, 32 };
        byte[] b2 = new byte[6];
        byte[] b3 = new byte[6];
        byte[] b4 = new byte[6];

        FileStream f1;
        f1 = new FileStream("test.txt", FileMode.Create, FileAccess.Write);

        // write the byte array into a new file
        f1.Write(b1, 0, 6);
        f1.Close();

        // read the byte array
        f1 = new FileStream("test.txt", FileMode.Open, FileAccess.Read);

        f1.Read(b2, 0, 6);
        f1.Close();

        // make changes to the byte array
        for (int i = 1; i < b2.Length; i++)
        {
            b2[i] = (byte)(b2[i] ^ (byte)10); //xor 10
        }

        f1 = new FileStream("test.txt", FileMode.Open, FileAccess.Write);
        // write the new byte array into the file
        f1.Write(b2, 0, 6);
        f1.Close();

        f1 = new FileStream("test.txt", FileMode.Open, FileAccess.Read);

        // read the byte array
        f1.Read(b3, 0, 6);
        f1.Close();

        // make changes to the byte array
        for (int i = 1; i < b3.Length; i++)
        {
            b4[i] = (byte)(b3[i] ^ (byte)10); //xor 10
        }

        f1 = new FileStream("test.txt", FileMode.Open, FileAccess.Write);

        // b4 will have the same values as b1
        f1.Write(b4, 0, 6);
        f1.Close();
        }
    }
}

Best practice is, in each module, to have a logger defined like this:

import logging
logger = logging.getLogger(__name__)

near the top of the module, and then in other code in the module do e.g.

logger.debug('My message with %s', 'variable data')

If you need to subdivide logging activity inside a module, use e.g.

loggerA = logging.getLogger(__name__ + '.A')
loggerB = logging.getLogger(__name__ + '.B')

and log to loggerA and loggerB as appropriate.

In your main program or programs, do e.g.:

def main():
    "your program code"

if __name__ == '__main__':
    import logging.config
    logging.config.fileConfig('/path/to/logging.conf')
    main()

or

def main():
    import logging.config
    logging.config.fileConfig('/path/to/logging.conf')
    # your program code

if __name__ == '__main__':
    main()

See here for logging from multiple modules, and here for logging configuration for code which will be used as a library module by other code.

Update: When calling fileConfig(), you may want to specify disable_existing_loggers=False if you're using Python 2.6 or later (see the docs for more information). The default value is True for backward compatibility, which causes all existing loggers to be disabled by fileConfig() unless they or their ancestor are explicitly named in the configuration. With the value set to False, existing loggers are left alone. If using Python 2.7/Python 3.2 or later, you may wish to consider the dictConfig() API which is better than fileConfig() as it gives more control over the configuration.

For Current Date and Time :

String mydate = java.text.DateFormat.getDateTimeInstance().format(Calendar.getInstance().getTime());

This will shown as :

Feb 5, 2013 12:40:24PM

In addition to the answer by fenix2222 (which worked for me) I had to modify the last line to:

config.Save(ConfigurationSaveMode.Modified);

Without this, the new value was still being written to the config file but the old value was retrieved when debugging.

Maybe you should check out the accepted answer to this (How to encrypt data in php using Public/Private keys?) question.

Instead of manually working around the message size limitation (or perhaps a trait) of RSA, it shows how to use the S/mime feature of OpenSSL to do the same thing and not needing to juggle with the symmetric key manually.

That's because if a class is abstract, then by definition you are required to create subclasses of it to instantiate. The subclasses will be required (by the compiler) to implement any interface methods that the abstract class left out.

Following your example code, try making a subclass of AbstractThing without implementing the m2 method and see what errors the compiler gives you. It will force you to implement this method.

In cases where the name attribute is different it is easiest to control the radio group via JQuery. When an option is selected use JQuery to un-select the other options.

There are many good answers, but I would use StringUtils from commons-lang. I find StringUtils.substringBefore() more readable than the alternatives:

String result = StringUtils.substringBefore("34.1 -118.33\n<!--ABCDEFG-->", "\n");

If you are using Python2.6 or newer, it's convenient to use socket.create_connection

sock = socket.create_connection(address, timeout=10)
sock.settimeout(None)
fileobj = sock.makefile('rb', 0)

Well, I think checking the type of variable can be done this way.

public <T extends Object> void checkType(T object) {    
    if (object instanceof Integer)
        System.out.println("Integer ");
    else if(object instanceof Double)
        System.out.println("Double ");
    else if(object instanceof Float)
        System.out.println("Float : ");
    else if(object instanceof List)
        System.out.println("List! ");
    else if(object instanceof Set)
        System.out.println("Set! ");
}

This way you need not have multiple overloaded methods. I think it is good practice to use collections over arrays due to the added benefits. Having said that, I do not know how to check for an array type. Maybe someone can improve this solution. Hope this helps!

P.S Yes, I know that this doesn't check for primitives as well.

If you use jquery, it can be done by using $(window).height();

<iframe src="html_intro.asp" width="100%" class="myIframe">
<p>Hi SOF</p>
</iframe>

<script type="text/javascript" language="javascript"> 
$('.myIframe').css('height', $(window).height()+'px');
</script>

Since version 0.15.0 this can now be easily done using .dt to access just the date component:

df['just_date'] = df['dates'].dt.date

The above returns a datetime.date dtype, if you want to have a datetime64 then you can just normalize the time component to midnight so it sets all the values to 00:00:00:

df['normalised_date'] = df['dates'].dt.normalize()

This keeps the dtype as datetime64, but the display shows just the date value.

• pandas: .dt accessor
• pandas.Series.dt

Assuming there is no problem doing a lookup on localhost (to 127.0.0.1), you need to make sure your server is listening to 127.0.0.1.

netstat works in both windows an UNIX. You probably need "netstat -a" to display listeners.

PLEASE do not use object as a class name:

public class MyObject //better to choose an appropriate name
{
    string id;
    DateTime date;
    public string ID
    {
       get { return id; }
       set { id = value; }
    }
    public DateTime Date
    {
       get { return date; }
       set { date = value; }
    }
}

You should implement INotifyPropertyChanged for this class and of course call it on the Property setter. Otherwise changes are not reflected in your ui.

Your Viewmodel class/ dialogbox class should have a Property of your MyObject list. ObservableCollection<MyObject> is the way to go:

public ObservableCollection<MyObject> MyList
{
     get...
     set...
}

In your xaml you should set the Itemssource to your collection of MyObject. (the Datacontext have to be your dialogbox class!)

<DataGrid ItemsSource="{Binding Source=MyList}"  AutoGenerateColumns="False">
   <DataGrid.Columns>                
     <DataGridTextColumn Header="ID" Binding="{Binding ID}"/>
     <DataGridTextColumn Header="Date" Binding="{Binding Date}"/>
   </DataGrid.Columns>
</DataGrid>

The overall dimensions of a range are in its Width and Height properties.

Jenkins stores some of the related builds data like the following:

• The working directory is stored in the directory {JENKINS_HOME}/workspace/.

  • Each job store its related temporal workspace folder in the directory {JENKINS_HOME}/workspace/{JOBNAME}

• The configuration for all jobs stored in the directory {JENKINS_HOME}/jobs/.

  • Each job store its related builds data in the directory {JENKINS_HOME}/jobs/{JOBNAME}

  • Each job folder contains:

    • The job configuration file is {JENKINS_HOME}/jobs/{JOBNAME}/config.xml

    • The job builds are stored in {JENKINS_HOME}/jobs/{JOBNAME}/builds/

See the Jenkins documentation for a visual representation and further details.

Note: This is a proper answer for a legacy version of AngularJS. See this question for updated versions.

$scope.$on('$routeChangeStart', function($event, next, current) { 
   // ... you could trigger something here ...
 });

The following events are also available (their callback functions take different arguments):

• $routeChangeSuccess
• $routeChangeError
• $routeUpdate - if reloadOnSearch property has been set to false

See the $route docs.

There are two other undocumented events:

• $locationChangeStart
• $locationChangeSuccess

See What's the difference between $locationChangeSuccess and $locationChangeStart?

It may happen that "this.checked" is always "on". Therefore, I recommend:

$('#checkbox').change(function() {
  if ($(this).is(':checked')) {
    console.log('Checked');
  } else {
    console.log('Unchecked');
  }
});

What solves my problem: I am using 64 bit Windows 7, so I thought I could install 64 bit Wamp. After I Installed the 32-bit version the error does not appear. So something in the developing process at Wamp went wrong...

What about something like this (might have rounding errors and negative-value issues that need debugging, left as an exercise for the reader):

printf("%.0d%.4g\n", (int)f/10, f-((int)f-(int)f%10));

It's slightly programmatic but at least it doesn't make you do any string manipulation.

My understanding is if you set controls.Visible = false during initial page load, it doesn't get rendered in the client response. My suggestion to solve your problem is

Don't use placeholder, judging from the scenario, you don't really need a placeholder, unless you need to dynamically add controls on the server side. Use div, without runat=server. You can always controls the visiblity of that div using css. If you need to add controls dynamically later, use placeholder, but don't set visible = false. Placeholder won't have any display anyway, Set the visibility of that placeholder using css. Here's how to do it programmactically :

placeholderId.Attributes["style"] = "display:none";

Anyway, as other have stated, your problems occurs because once you set control.visible = false, it doesn't get rendered in the client response.

You can try this:table1.GroupBy(t => t.Text).Select(shape => shape.r)).Distinct();

You could use get twice:

example_dict.get('key1', {}).get('key2')

This will return None if either key1 or key2 does not exist.

Note that this could still raise an AttributeError if example_dict['key1'] exists but is not a dict (or a dict-like object with a get method). The try..except code you posted would raise a TypeError instead if example_dict['key1'] is unsubscriptable.

Another difference is that the try...except short-circuits immediately after the first missing key. The chain of get calls does not.

If you wish to preserve the syntax, example_dict['key1']['key2'] but do not want it to ever raise KeyErrors, then you could use the Hasher recipe:

class Hasher(dict):
    # https://stackoverflow.com/a/3405143/190597
    def __missing__(self, key):
        value = self[key] = type(self)()
        return value

example_dict = Hasher()
print(example_dict['key1'])
# {}
print(example_dict['key1']['key2'])
# {}
print(type(example_dict['key1']['key2']))
# <class '__main__.Hasher'>

Note that this returns an empty Hasher when a key is missing.

Since Hasher is a subclass of dict you can use a Hasher in much the same way you could use a dict. All the same methods and syntax is available, Hashers just treat missing keys differently.

You can convert a regular dict into a Hasher like this:

hasher = Hasher(example_dict)

and convert a Hasher to a regular dict just as easily:

regular_dict = dict(hasher)

Another alternative is to hide the ugliness in a helper function:

def safeget(dct, *keys):
    for key in keys:
        try:
            dct = dct[key]
        except KeyError:
            return None
    return dct

So the rest of your code can stay relatively readable:

safeget(example_dict, 'key1', 'key2')

5 Columns with Bootstrap 4

Here is 5 equal, full-width columns (no extra CSS or SASS) using the auto-layout grid..

<div class="container-fluid">
    <div class="row">
        <div class="col">1</div>
        <div class="col">2</div>
        <div class="col">3</div>
        <div class="col">4</div>
        <div class="col">5</div>
    </div>
</div>

http://codeply.com/go/MJTglTsq9h

This solution works because Bootstrap 4 is now flexbox. You can get the 5 colums to wrap within the same .row using a clearfix break such as <div class="col-12"></div> or <div class="w-100"></div> very 5 columns.

Update 2020

As of Bootstrap 4.4, you can also use the row-cols-5 class on the row...

<div class="container">
    <div class="row row-cols-5">
        <div class="col">
            X
        </div>
        <div class="col">
            X
        </div>
        <div class="col">
            X
        </div>
        <div class="col">
            X
        </div>
        <div class="col">
            X
        </div>
        <div class="col">
            X
        </div>
    </div>
</div>

Whatever function is a class so you can take the name of the class of instance x and compare:

if(x.__class__.__name__ == 'function'):
     print "it's a function"

We cannot always depend on ERRORLEVEL, because many times external programs or batch scripts do not return exit codes.

In that case we can use generic checks for failures like this:

IF EXIST %outfile% (DEL /F %outfile%)
CALL some_script.bat -o %outfile%
IF NOT EXIST %outfile%  (ECHO ERROR & EXIT /b)

And if the program outputs something to console, we can check it also.

some_program.exe 2>&1 | FIND "error message here" && (ECHO ERROR & EXIT /b)
some_program.exe 2>&1 | FIND "Done processing." || (ECHO ERROR & EXIT /b)

I got the same error using:

<link rel="stylesheet" href="//fonts.googleapis.com/css?family=Source+Sans+Pro:400,400i,700,700i,900,900i" type="text/css" media="all">

But once I added https: in the beginning of the href the error disappeared.

<link rel="stylesheet" href="https://fonts.googleapis.com/css?family=Source+Sans+Pro:400,400i,700,700i,900,900i" type="text/css" media="all">

The Print statement in TSQL is a misunderstood creature, probably because of its name. It actually sends a message to the error/message-handling mechanism that then transfers it to the calling application. PRINT is pretty dumb. You can only send 8000 characters (4000 unicode chars). You can send a literal string, a string variable (varchar or char) or a string expression. If you use RAISERROR, then you are limited to a string of just 2,044 characters. However, it is much easier to use it to send information to the calling application since it calls a formatting function similar to the old printf in the standard C library. RAISERROR can also specify an error number, a severity, and a state code in addition to the text message, and it can also be used to return user-defined messages created using the sp_addmessage system stored procedure. You can also force the messages to be logged.

Your error-handling routines won’t be any good for receiving messages, despite messages and errors being so similar. The technique varies, of course, according to the actual way you connect to the database (OLBC, OLEDB etc). In order to receive and deal with messages from the SQL Server Database Engine, when you’re using System.Data.SQLClient, you’ll need to create a SqlInfoMessageEventHandler delegate, identifying the method that handles the event, to listen for the InfoMessage event on the SqlConnection class. You’ll find that message-context information such as severity and state are passed as arguments to the callback, because from the system perspective, these messages are just like errors.

It is always a good idea to have a way of getting these messages in your application, even if you are just spooling to a file, because there is always going to be a use for them when you are trying to chase a really obscure problem. However, I can’t think I’d want the end users to ever see them unless you can reserve an informational level that displays stuff in the application.

HTML5 spec:

http://www.w3.org/TR/html5/forms.html#attr-input-checked :

The disabled content attribute is a boolean attribute.

http://www.w3.org/TR/html5/infrastructure.html#boolean-attributes :

The presence of a boolean attribute on an element represents the true value, and the absence of the attribute represents the false value.

If the attribute is present, its value must either be the empty string or a value that is an ASCII case-insensitive match for the attribute's canonical name, with no leading or trailing whitespace.

Conclusion:

The following are valid, equivalent and true:

<input type="checkbox" checked />
<input type="checkbox" checked="" />
<input type="checkbox" checked="checked" />
<input type="checkbox" checked="ChEcKeD" />

The following are invalid:

<input type="checkbox" checked="0" />
<input type="checkbox" checked="1" />
<input type="checkbox" checked="false" />
<input type="checkbox" checked="true" />

The absence of the attribute is the only valid syntax for false:

<input />

Recommendation

If you care about writing valid XHTML, use checked="checked", since <input checked> is invalid XHTML (but valid HTML) and other alternatives are less readable. Else, just use <input checked> as it is shorter.

I've created an API to create an Excel file more easier.

Create Excel - Creating Excel from Template

Just set the required values upon instantiation then invoke execute(), it will be created based on your desired output directory.

But before you use this, you must have an Excel Template which will be use as a template of the newly created Excel file.

Also, you need Apache POI in your project's class path.

To get the number of days the easiest way would be:

SELECT EXTRACT(DAY FROM NOW() - '2014-08-02 08:10:56');

As far as I know it would return the same as:

SELECT (EXTRACT(epoch FROM (SELECT (NOW() - '2014-08-02 08:10:56')))/86400)::int;

What would be handy would be to apply the Camera position to a new plot. So I plot, then move the plot around with the mouse changing the distance. Then try to replicate the view including the distance on another plot. I find that axx.ax.get_axes() gets me an object with the old .azim and .elev.

IN PYTHON...

axx=ax1.get_axes()
azm=axx.azim
ele=axx.elev
dst=axx.dist       # ALWAYS GIVES 10
#dst=ax1.axes.dist # ALWAYS GIVES 10
#dst=ax1.dist      # ALWAYS GIVES 10

Later 3d graph...

ax2.view_init(elev=ele, azim=azm) #Works!
ax2.dist=dst                       # works but always 10 from axx

EDIT 1... OK, Camera position is the wrong way of thinking concerning the .dist value. It rides on top of everything as a kind of hackey scalar multiplier for the whole graph.

This works for the magnification/zoom of the view:

xlm=ax1.get_xlim3d() #These are two tupples
ylm=ax1.get_ylim3d() #we use them in the next
zlm=ax1.get_zlim3d() #graph to reproduce the magnification from mousing
axx=ax1.get_axes()
azm=axx.azim
ele=axx.elev

Later Graph...

ax2.view_init(elev=ele, azim=azm) #Reproduce view
ax2.set_xlim3d(xlm[0],xlm[1])     #Reproduce magnification
ax2.set_ylim3d(ylm[0],ylm[1])     #...
ax2.set_zlim3d(zlm[0],zlm[1])     #...

If you use Iclick pluging, it is as simply as you see below.

 $('#radio1').iCheck('uncheck');

In case anybody comes back to this, I think the problem here was failing to install the parent pom first, which all these submodules depend on, so the Maven Reactor can't collect the necessary dependencies to build the submodule.

So from the root directory (here D:\luna_workspace\empire_club\empirecl) it probably just needs a:

mvn clean install

(Aside: <relativePath>../pom.xml</relativePath> is not really necessary as it's the default value).

This takes care of nulls

var body = JObject.Parse("anyjsonString");

body?.SelectToken("path-string-prop")?.ToString();

body?.SelectToken("path-double-prop")?.ToObject<double>();

As of Android studio 3.4, You need to put this line in your Layout which holds the RecyclerView.

app:layout_behavior="android.support.design.widget.AppBarLayout$ScrollingViewBehavior"

There could be another way to achieve what you want. Basically,

1. Use the find command to output path to whatever files you're looking for. Redirect stdout to a filename of your choosing.

2. Then tar with the -T option which allows it to take a list of file locations (the one you just created with find!)

   find . -name "*.whatever" > yourListOfFiles
   tar -cvf yourfile.tar -T yourListOfFiles
   

I'm surprised how nobody has suggested this yet. It's super clean and very explicit about which keys you want to keep.

const unfilteredObj = {a: ..., b:..., c:..., x:..., y:...}

const filterObject = ({a,b,c}) => ({a,b,c})
const filteredObject = filterObject(unfilteredObject)

Or if you want a dirty one liner:

const unfilteredObj = {a: ..., b:..., c:..., x:..., y:...}

const filteredObject = (({a,b,c})=>({a,b,c}))(unfilteredObject);

You need to use a while loop. If you make a while loop, and there's no instruction after the loop, it'll become an infinite loop,and won't stop until you manually stop it.

With VSCode 1.43 (Q1 2020), those Alt+? / Alt+?, or Ctrl+- / Ctrl+Shift+- will also... preserve selection.

See issue 89699:

Benjamin Pasero (bpasero) adds:

going back/forward restores selections as they were.

Note that in order to get a history entry there needs to be at least 10 lines between the positions to consider the entry as new entry.

Seems nobody noticed that -x operator does not differ file with directory.

So to precisely check an executable file, you may use [[ -f SomeFile && -x SomeFile ]]

This will give you BOTH the distinct column values and the count of each value. I usually find that I want to know both pieces of information.

SELECT [columnName], count([columnName]) AS CountOf
FROM [tableName]
GROUP BY [columnName]

Although it is quite an old question, another approach is to change AppendDataBoundItems property. So the code will be:

<asp:DropDownList ID="DropDownList1" runat="server" AutoPostBack="True"
                  OnSelectedIndexChanged="DropDownList1_SelectedIndexChanged"
                  AppendDataBoundItems="True">
     <asp:ListItem Selected="True" Value="0" Text="Select"></asp:ListItem>
</asp:DropDownList>

YES, a declarative programming language.

You really want to list the most important things you know that are relative to the job you're applying for on your resume. If you list ASP.NET but don't list HTML, even though it's somewhat obvious, there are a lot of managers and/or HR types that will assume you don't know HTML since it's not listed. I've had it happen to me before.

Update - Some say no it isn't a programming language, and you may not agree with me on this, but regardless on a resume it IS a programming language. You get HR types looking at your resume before the hiring manager even sees it. If the manager says you need to know HTML, and it's not listed in the 'programming languages' section then the HR person may disregard you resume thinking you don't know it because it's not listed.

Update 6-8-2012: Any instruction that tells the computer to do something is a programming language. So even after all these years, I still stand by my answer. HTML is a programming language. Something that isn't a programming language would be XML.

I created a new namespace (and therefore folder) identical to the route to a controller (e.g. MvcApp/Test/SomeClasses.cs and MvcApp/Controllers/TestController.cs). This resulted also in a 403.14!

Just revisiting an old solution, I thought I'd give it a facelift for it's ~5 year anniversary!

• Plain Javascript (ES6)
• Does alpha and numeric sorting - ascending and descending
• Works in Chrome, Firefox, Safari (and IE11, see below)

Quick explanation

1. add a click event to all header (th) cells...
   1. for the current table, find all rows (except the first)...
   2. sort the rows, based on the value of the clicked column...
   3. insert the rows back into the table, in the new order.

const getCellValue = (tr, idx) => tr.children[idx].innerText || tr.children[idx].textContent;_x000D_
_x000D_
const comparer = (idx, asc) => (a, b) => ((v1, v2) => _x000D_
    v1 !== '' && v2 !== '' && !isNaN(v1) && !isNaN(v2) ? v1 - v2 : v1.toString().localeCompare(v2)_x000D_
    )(getCellValue(asc ? a : b, idx), getCellValue(asc ? b : a, idx));_x000D_
_x000D_
// do the work..._x000D_
document.querySelectorAll('th').forEach(th => th.addEventListener('click', (() => {_x000D_
    const table = th.closest('table');_x000D_
    Array.from(table.querySelectorAll('tr:nth-child(n+2)'))_x000D_
        .sort(comparer(Array.from(th.parentNode.children).indexOf(th), this.asc = !this.asc))_x000D_
        .forEach(tr => table.appendChild(tr) );_x000D_
})));

table, th, td {_x000D_
    border: 1px solid black;_x000D_
}_x000D_
th {_x000D_
    cursor: pointer;_x000D_
}

<table>_x000D_
    <tr><th>Country</th><th>Date</th><th>Size</th></tr>_x000D_
    <tr><td>France</td><td>2001-01-01</td><td><i>25</i></td></tr>_x000D_
    <tr><td><a href=#>spain</a></td><td><i>2005-05-05</i></td><td></td></tr>_x000D_
    <tr><td><b>Lebanon</b></td><td><a href=#>2002-02-02</a></td><td><b>-17</b></td></tr>_x000D_
    <tr><td><i>Argentina</i></td><td>2005-04-04</td><td><a href=#>100</a></td></tr>_x000D_
    <tr><td>USA</td><td></td><td>-6</td></tr>_x000D_
</table>

IE11 Support (non-ES6)

If you want to support IE11, you'll need to ditch the ES6 syntax and use alternatives to Array.from and Element.closest.

i.e.

var getCellValue = function(tr, idx){ return tr.children[idx].innerText || tr.children[idx].textContent; }

var comparer = function(idx, asc) { return function(a, b) { return function(v1, v2) {
        return v1 !== '' && v2 !== '' && !isNaN(v1) && !isNaN(v2) ? v1 - v2 : v1.toString().localeCompare(v2);
    }(getCellValue(asc ? a : b, idx), getCellValue(asc ? b : a, idx));
}};

// do the work...
Array.prototype.slice.call(document.querySelectorAll('th')).forEach(function(th) { th.addEventListener('click', function() {
        var table = th.parentNode
        while(table.tagName.toUpperCase() != 'TABLE') table = table.parentNode;
        Array.prototype.slice.call(table.querySelectorAll('tr:nth-child(n+2)'))
            .sort(comparer(Array.prototype.slice.call(th.parentNode.children).indexOf(th), this.asc = !this.asc))
            .forEach(function(tr) { table.appendChild(tr) });
    })
});

You will have to change some of your data types but the basics of what you just posted could be converted to something similar to this given the data types I used may not be accurate.

Dim DateToday As String: DateToday = Format(Date, "yyyy/MM/dd")
Dim Computers As New Collection
Dim disabledList As New Collection
Dim compArray(1 To 1) As String

'Assign data to first item in array
compArray(1) = "asdf"

'Format = Item, Key
Computers.Add "ErrorState", "Computer Name"

'Prints "ErrorState"
Debug.Print Computers("Computer Name")

Collections cannot be sorted so if you need to sort data you will probably want to use an array.

Here is a link to the outlook developer reference. http://msdn.microsoft.com/en-us/library/office/ff866465%28v=office.14%29.aspx

Another great site to help you get started is http://www.cpearson.com/Excel/Topic.aspx

Moving everything over to VBA from VB.Net is not going to be simple since not all the data types are the same and you do not have the .Net framework. If you get stuck just post the code you're stuck converting and you will surely get some help!

Edit:

Sub ArrayExample()
    Dim subject As String
    Dim TestArray() As String
    Dim counter As Long

    subject = "Example"
    counter = Len(subject)

    ReDim TestArray(1 To counter) As String

    For counter = 1 To Len(subject)
        TestArray(counter) = Right(Left(subject, counter), 1)
    Next
End Sub

This is known as a Shebang:

http://en.wikipedia.org/wiki/Shebang_(Unix)

#!interpreter [optional-arg]

A shebang is only relevant when a script has the execute permission (e.g. chmod u+x script.sh).

When a shell executes the script it will use the specified interpreter.

Example:

#!/bin/bash
# file: foo.sh
echo 1

$ chmod u+x foo.sh
$ ./foo.sh
  1

I found the answer. IE stores passwords in two different locations based on the password type:

• Http-Auth: %APPDATA%\Microsoft\Credentials, in encrypted files
• Form-based: HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\IntelliForms\Storage2, encrypted with the url

From a very good page on NirSoft.com:

Starting from version 7.0 of Internet Explorer, Microsoft completely changed the way that passwords are saved. In previous versions (4.0 - 6.0), all passwords were saved in a special location in the Registry known as the "Protected Storage". In version 7.0 of Internet Explorer, passwords are saved in different locations, depending on the type of password. Each type of passwords has some limitations in password recovery:

• AutoComplete Passwords: These passwords are saved in the following location in the Registry: HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\IntelliForms\Storage2 The passwords are encrypted with the URL of the Web sites that asked for the passwords, and thus they can only be recovered if the URLs are stored in the history file. If you clear the history file, IE PassView won't be able to recover the passwords until you visit again the Web sites that asked for the passwords. Alternatively, you can add a list of URLs of Web sites that requires user name/password into the Web sites file (see below).

• HTTP Authentication Passwords: These passwords are stored in the Credentials file under Documents and Settings\Application Data\Microsoft\Credentials, together with login passwords of LAN computers and other passwords. Due to security limitations, IE PassView can recover these passwords only if you have administrator rights.

In my particular case it answers the question of where; and I decided that I don't want to duplicate that. I'll continue to use CredRead/CredWrite, where the user can manage their passwords from within an established UI system in Windows.

If you don't want to include a whole library, you can use this one off to add a method that any array can use:

Array.prototype.uniq = function uniq() {
  return this.reduce(function(accum, cur) { 
    if (accum.indexOf(cur) === -1) accum.push(cur); 
    return accum; 
  }, [] );
}

["Mike","Matt","Nancy","Adam","Jenny","Nancy","Carl"].uniq()

There is no tool specifically in the 'setup.exe' installer that offers the functionality of apt-get. There is, however, a command-line package installer for Cygwin that can be downloaded separately, but it is not entirely stable and relies on workarounds.

apt-cyg: http://github.com/transcode-open/apt-cyg

Check out the issues tab for the project to see the known problems.

You can set the following environment variable:

PIP_TARGET=/path/to/pip/dir

I found this question when I got the same error for a different reason.

My issue was that my Gulp hadn't picked up on the fact that I had declared a new module and I needed to manually re-run Gulp.

You want the Except operator.

var answer = list1.Except(list2);

Better explanation here: https://docs.microsoft.com/archive/blogs/charlie/linq-farm-more-on-set-operators

NOTE: This technique works best for primitive types only, since you have to implement an IEqualityComparer to use the Except method with complex types.

This will explain better.

EntityManager em = new JPAUtil().getEntityManager();
Session session = em.unwrap(Session.class);
Criteria c = session.createCriteria(Name.class);

Few steps that helped me (some of them are mentioned above):

Open project structure by:

command + ; (mac users) OR right click on the project -> Open Module Settings

1. Facets -> + -> Python -> <your-project> -> OK
2. Modules -> Python -> <select python interpreter>
3. Project -> Project SDK -> <select relevant SDK>
4. SDKs -> <make sure it's the right one>

Click OK.

Open Run/Debug Configurations by: Run -> Edit Configurations

5. Python Interpreter -> <make sure it's the right one>

Click OK.

UPDATE tblKit
SET number = REPLACE(number, 'KIT', 'CH')
WHERE number like 'KIT%'

• SQLFiddle Demo

or simply this if you are sure that you have no values like this CKIT002

UPDATE tblKit
SET number = REPLACE(number, 'KIT', 'CH')

• SQLFiddle Demo

This way added by Sebastiano was OK, but it's necessary, when you run tests from i.e. IntelliJ IDE to add:

 try {
    // clearing app data
    Runtime runtime = Runtime.getRuntime();
    runtime.exec("adb shell pm clear YOUR_APP_PACKAGE_GOES HERE");

}

instead of only "pm package..."

and more important: add it before driver.setCapability(App_package, package_name).

Complete working example in Kotlin, I have replaced my API keys with 1111...

        val apiService = API.getInstance().retrofit.create(MyApiEndpointInterface::class.java)
        val params = HashMap<String, String>()
        params["q"] =  "munich,de"
        params["APPID"] = "11111111111111111"

        val call = apiService.getWeather(params)

        call.enqueue(object : Callback<WeatherResponse> {
            override fun onFailure(call: Call<WeatherResponse>?, t: Throwable?) {
                Log.e("Error:::","Error "+t!!.message)
            }

            override fun onResponse(call: Call<WeatherResponse>?, response: Response<WeatherResponse>?) {
                if (response != null && response.isSuccessful && response.body() != null) {
                    Log.e("SUCCESS:::","Response "+ response.body()!!.main.temp)

                    temperature.setText(""+ response.body()!!.main.temp)

                }
            }

        })

You can use proxy-initial-not-pooled

See http://httpd.apache.org/docs/2.2/mod/mod_proxy_http.html :

If this variable is set no pooled connection will be reused if the client connection is an initial connection. This avoids the "proxy: error reading status line from remote server" error message caused by the race condition that the backend server closed the pooled connection after the connection check by the proxy and before data sent by the proxy reached the backend. It has to be kept in mind that setting this variable downgrades performance, especially with HTTP/1.0 clients.

We had this problem, too. We fixed it by adding

SetEnv proxy-nokeepalive 1
SetEnv proxy-initial-not-pooled 1

and turning keepAlive on all servers off.

mod_proxy_http is fine in most scenarios but we are running it with heavy load and we still got some timeout problems we do not understand.

But see if the above directive fits your needs.

One think you should change is the call $state.go(). As described here:

• $state.go(to [, toParams] [, options])

The param passed should be the state name

$scope.create = function() {
  // instead of this
  //$state.go("/tab/newpost"); 

  // we should use this
  $state.go("tab.newpost"); 
};

Some cite from doc (the first parameter to of the [$state.go(to \[, toParams\] \[, options\]):

to

String Absolute State Name or Relative State Path

The name of the state that will be transitioned to or a relative state path. If the path starts with ^ or . then it is relative, otherwise it is absolute.

Some examples:

$state.go('contact.detail') will go to the 'contact.detail' state
$state.go('^') will go to a parent state.
$state.go('^.sibling') will go to a sibling state.
$state.go('.child.grandchild') will go to a grandchild state.

For me adding AppRoutingModule to my imports solved the problem.

    imports: [
     BrowserModule,
     AppRoutingModule,
     RouterModule.forRoot([
      {
        path: 'new-cmp',
        component: NewCmpComponent
      }
     ])
    ]

Whereas @jbarrueta answer is perfect, in the 2.12 version of Jackson was introduced a new long-awaited type for the @JsonTypeInfo annotation, DEDUCTION.

It is useful for the cases when you have no way to change the incoming json or must not do so. I'd still recommend to use use = JsonTypeInfo.Id.NAME, as the new way may throw an exception in complex cases when it has no way to determine which subtype to use.

Now you can simply write

import com.fasterxml.jackson.annotation.JsonIgnoreProperties;
import com.fasterxml.jackson.annotation.JsonSubTypes;
import com.fasterxml.jackson.annotation.JsonTypeInfo;

@JsonIgnoreProperties(ignoreUnknown = true)
@JsonTypeInfo(use = JsonTypeInfo.Id.DEDUCTION)
@JsonSubTypes({
    @JsonSubTypes.Type(Dog.class),
    @JsonSubTypes.Type(Cat.class) }
)
public abstract class Animal {

    private String name;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

}

And it will produce {"name":"ruffus", "breed":"english shepherd"} and {"name":"goya", "favoriteToy":"mice"}

Once again, it's safer to use NAME if some of the fields may be not present, like breed or favoriteToy.

1. open the Build Variants pane, typically found along the lower left side of the window:

2. set debug to release
3. shift+f10 run!!

then, Android Studio will execute assembleRelease task and install xx-release.apk to your device.

Because your program now contains two copies of the foo function, once inside foo.cpp and once inside main.cpp

Think of #include as an instruction to the compiler to copy/paste the contents of that file into your code, so you'll end up with a processed main.cpp that looks like this

#include <iostream> // actually you'll get the contents of the iostream header here, but I'm not going to include it!
int foo(int a){
    return ++a;
}

int main(int argc, char *argv[])
{
int x=42;
std::cout << x <<std::endl;
std::cout << foo(x) << std::endl;
return 0;
}

and foo.cpp

int foo(int a){
    return ++a;
}

hence the multiple definition error

Once you have cloned the repo, you have everything: you can then hg up branchname or hg up tagname to update your working copy.

UP: hg up is a shortcut of hg update, which also has hg checkout alias for people with git habits.

The answer by Tatu is how I would intuitively do it, but I have experienced some problems in Internet Explorer with this way of nesting/binding the events, even though it is done through the .on() method.

I havn't been able to pinpoint exactly which versions of jQuery this is the problem with. But I sometimes see the problem in the following versions:

• 2.0.2
• 1.10.1
• 1.6.4
• Mobile 1.3.0b1
• Mobile 1.4.2
• Mobile 1.2.0

My workaround have been to first define the function,

function myFunction() {
    ...
}

and then handle the events individually

// Call individually due to IE not handling binds properly
$(window).on("scroll", myFunction);
$(window).on("resize", myFunction);

This is not the prettiest solution, but it works for me, and I thought I would put it out there to help others that might stumble upon this issue

If for some reason you don't want to use the plugin, then here's the script you can use to copy the resources to your android studio project:

echo "..:: Copying resources ::.."
echo "Enter folder:"
read srcFolder
echo "Enter filename with extension:"
read srcFile
cp /Users/YOUR_USER/Downloads/material-design-icons-master/"$srcFolder"/drawable-xxxhdpi/"$srcFile" /Users/YOUR_USER/AndroidStudioProjects/YOUR_PROJECT/app/src/main/res/drawable-xxxhdpi/"$srcFile"/
echo "xxxhdpi copied"
cp /Users/YOUR_USER/Downloads/material-design-icons-master/"$srcFolder"/drawable-xxhdpi/"$srcFile" /Users/YOUR_USER/AndroidStudioProjects/YOUR_PROJECT/app/src/main/res/drawable-xxhdpi/"$srcFile"/
echo "xxhdpi copied"
cp /Users/YOUR_USER/Downloads/material-design-icons-master/"$srcFolder"/drawable-xhdpi/"$srcFile" /Users/YOUR_USER/AndroidStudioProjects/YOUR_PROJECT/app/src/main/res/drawable-xhdpi/"$srcFile"/
echo "xhdpi copied"
cp /Users/YOUR_USER/Downloads/material-design-icons-master/"$srcFolder"/drawable-hdpi/"$srcFile" /Users/YOUR_USER/AndroidStudioProjects/YOUR_PROJECT/app/src/main/res/drawable-hdpi/"$srcFile"/
echo "hdpi copied"
cp /Users/YOUR_USER/Downloads/material-design-icons-master/"$srcFolder"/drawable-mdpi/"$srcFile" /Users/YOUR_USER/AndroidStudioProjects/YOUR_PROJECT/app/src/main/res/drawable-mdpi/"$srcFile"/
echo "mdpi copied"

Update: a better idea, set the "AppendDataBoundItems" property to true, then declare the "Choose item" declaratively. The databinding operation will add to the statically declared item.

<asp:DropDownList ID="ddl" runat="server" AppendDataBoundItems="true">
    <asp:ListItem Value="0" Text="Please choose..."></asp:ListItem>
</asp:DropDownList>

What about injecting the class attribute after the class definition?

class Klass(object):

    @staticmethod  # use as decorator
    def stat_func():
        return 42

    def method(self):
        ret = Klass.stat_func()
        return ret

Klass._ANS = Klass.stat_func()  # inject the class attribute with static method value

You can access the members by their index in the tuple.

lst = [(1,'on'),(2,'onn'),(3,'onnn'),(4,'onnnn'),(5,'onnnnn')]

def unFld(x):

    for i in x:
        print(i[0],' ',i[1])

print(unFld(lst))

Output :

1    on

2    onn

3    onnn

4    onnnn

5    onnnnn

select @EmpID = ID from dbo.Employee

Or

set @EmpID =(select id from dbo.Employee)

Note that the select query might return more than one value or rows. so you can write a select query that must return one row.

If you would like to add more columns to one variable(MS SQL), there is an option to use table defined variable

DECLARE @sampleTable TABLE(column1 type1)
INSERT INTO @sampleTable
SELECT columnsNumberEqualInsampleTable FROM .. WHERE ..

As table type variable do not exist in Oracle and others, you would have to define it:

DECLARE TYPE type_name IS TABLE OF (column_type | variable%TYPE | table.column%TYPE [NOT NULL] INDEX BY BINARY INTEGER;

-- Then to declare a TABLE variable of this type: variable_name type_name;

-- Assigning values to a TABLE variable: variable_name(n).field_name := 'some text';

-- Where 'n' is the index value

This error has a chance of triggering when the API version AVD which you selected is not the same as you specified in Project_folder>android>app>build.gradle as compileSdkVersion and targetSdkVersion.

Earlier my API version was 27 and now it is 30. I have changed the values of the above two parameters to 30 and my problem got solved.

Is it possible to dereference the void pointer without type-casting in C programming language...

No, void indicates the absence of type, it is not something you can dereference or assign to.

is there is any way of generalizing a function which can receive pointer and store it in void pointer and by using that void pointer we can make a generalized function..

You cannot just dereference it in a portable way, as it may not be properly aligned. It may be an issue on some architectures like ARM, where pointer to a data type must be aligned at boundary of the size of data type (e.g. pointer to 32-bit integer must be aligned at 4-byte boundary to be dereferenced).

For example, reading uint16_t from void*:

/* may receive wrong value if ptr is not 2-byte aligned */
uint16_t value = *(uint16_t*)ptr;
/* portable way of reading a little-endian value */
uint16_t value = *(uint8_t*)ptr
                | ((*((uint8_t*)ptr+1))<<8);

Also, is pointer arithmetic with void pointers possible...

Pointer arithmetic is not possible on pointers of void due to lack of concrete value underneath the pointer and hence the size.

void* p = ...
void *p2 = p + 1; /* what exactly is the size of void?? */

You are using incorrect overload. You should use this overload

public static MvcHtmlString ActionLink(
    this HtmlHelper htmlHelper,
    string linkText,
    string actionName,
    string controllerName,
    Object routeValues,
    Object htmlAttributes
) 

And the correct code would be

<%= Html.ActionLink("Create New Part", "CreateParts", "PartList", new { parentPartId = 0 }, null)%>

Note that extra parameter at the end. For the other overloads, visit LinkExtensions.ActionLink Method. As you can see there is no string, string, string, object overload that you are trying to use.

This is not possible from HTML on. The closest what you can get is the accept-charset attribute of the <form>. Only MSIE browser adheres that, but even then it is doing it wrong (e.g. CP1252 is actually been used when it says that it has sent ISO-8859-1). Other browsers are fully ignoring it and they are using the charset as specified in the Content-Type header of the response. Setting the character encoding right is basically fully the responsiblity of the server side. The client side should just send it back in the same charset as the server has sent the response in.

To the point, you should really configure the character encoding stuff entirely from the server side on. To overcome the inability to edit URIEncoding attribute, someone here on SO wrote a (complex) filter: Detect the URI encoding automatically in Tomcat. You may find it useful as well (note: I haven't tested it).

Update: Noted should be that the meta tag as given in your question is ignored when the content is been transferred over HTTP. Instead, the HTTP response Content-Type header will be used to determine the content type and character encoding. You can determine the HTTP header with for example Firebug, in the Net panel.

As many have already told you:

mainList.get(3);

Be sure to check the ArrayList Javadoc.

Also, be careful with the arrays indices: in Java, the first element is at index 0. So if you are trying to get the third element, your solution would be mainList.get(2);

If you are working with core java, create your file(.properties) by right clicking your project. If the file is present inside your package or src folder it will throw an file not found error

Because that syntax simply isn't defined? Besides, x < y evaluates as a bool, so what does bool < int mean? It isn't really an overhead; besides, you could write a utility method if you really want - isBetween(10,x,20) - I wouldn't myself, but hey...

If you want to get values in Javascript on frontend, you can use the native way to do it by using :

document.getElementsByName("movie")[0].value;

Where "movie" is the name of your input <input type="text" name="movie">

If you want to get it on angular.js controller, you can use;

$scope.movie

var output = '';
for (var property in object) {
  output += property + ': ' + object[property]+'; ';
}
alert(output);

To extend answers above, you cannot use Guid default value with Guid.Empty as an optional argument in method, indexer or delegate definition, because it will give you compile time error. Use default(Guid) or new Guid() instead.

This won't work. You first have to initialize the array. So far, you only have a String[] reference, pointing to null.

When you try to read the length member, what you actually do is null.length, which results in a NullPointerException.

If you want to pass the result as a rendered template you have to load and render a template, pass the result of rendering it to the json.This could look like that:

from django.template import loader, RequestContext

#render the template
t=loader.get_template('sample/sample.html')
context=RequestContext()
html=t.render(context)

#create the json
result={'html_result':html)
json = simplejson.dumps(result)

return HttpResponse(json)

That way you can pass a rendered template as json to your client. This can be useful if you want to completely replace ie. a containing lots of different elements.

In python, A dynamic array is an 'array' from the array module. E.g.

from array import array
x = array('d')          #'d' denotes an array of type double
x.append(1.1)
x.append(2.2)
x.pop()                 # returns 2.2

This datatype is essentially a cross between the built-in 'list' type and the numpy 'ndarray' type. Like an ndarray, elements in arrays are C types, specified at initialization. They are not pointers to python objects; this may help avoid some misuse and semantic errors, and modestly improves performance.

However, this datatype has essentially the same methods as a python list, barring a few string & file conversion methods. It lacks all the extra numerical functionality of an ndarray.

See https://docs.python.org/2/library/array.html for details.

You can also use reduce method:

>>> myList = [3, 5, 4, 9]
>>> myTotal = reduce(lambda x,y: x+y, myList)
>>> myTotal
21

Furthermore, you can modify the lambda function to do other operations on your list.

The Merge method takes the values from the second table and merges them in with the first table, so the first will now hold the values from both.

If you want to preserve both of the original tables, you could copy the original first, then merge:

dtAll = dtOne.Copy();
dtAll.Merge(dtTwo);

$(sudo run command)

If you're going to use an apostrophe, you need `, not '. This character is called "backticks" (or "grave accent"):

#!/bin/bash

VAR1="$1"
VAR2="$2"

MOREF=`sudo run command against "$VAR1" | grep name | cut -c7-`

echo "$MOREF"

Just in case anyone wants yet another solution:

1. Check in your new folder as "foldername2"
2. Go into Tortise SVN repo browser
3. Rename "foldername2" to "foldername"
4. In windows explorer do an update

Hope it helps someone.

I've just updated my blog post to correct the error in the script that you were having Jeff, you can see the updated script here: Search all fields in SQL Server Database

This should do it:

declare
    v_count integer;
begin

    for r in (select table_name, owner from all_tables
              where owner = 'SCHEMA_NAME') 
    loop
        execute immediate 'select count(*) from ' || r.table_name 
            into v_count;
        INSERT INTO STATS_TABLE(TABLE_NAME,SCHEMA_NAME,RECORD_COUNT,CREATED)
        VALUES (r.table_name,r.owner,v_count,SYSDATE);
    end loop;

end;

I removed various bugs from your code.

Note: For the benefit of other readers, Oracle does not provide a table called STATS_TABLE, you would need to create it.

Using this answer which provides the code to use Dom4j to do pretty-printing, change the line that sets the output format from: createPrettyPrint() to: createCompactFormat()

public String unPrettyPrint(final String xml){  

    if (StringUtils.isBlank(xml)) {
        throw new RuntimeException("xml was null or blank in unPrettyPrint()");
    }

    final StringWriter sw;

    try {
        final OutputFormat format = OutputFormat.createCompactFormat();
        final org.dom4j.Document document = DocumentHelper.parseText(xml);
        sw = new StringWriter();
        final XMLWriter writer = new XMLWriter(sw, format);
        writer.write(document);
    }
    catch (Exception e) {
        throw new RuntimeException("Error un-pretty printing xml:\n" + xml, e);
    }
    return sw.toString();
}

You want to iterate through the list, sum all the numbers, and then divide the sum by the number of elements in the list. You can use a for loop to accomplish this.

average = 0
sum = 0    
for n in numbers:
    sum = sum + n
average = sum / len(numbers)

The for loop looks at each element in the list, and then adds it to the current sum. You then divide by the length of the list (or the number of elements in the list) to find the average.

I would recommend googling a python reference to find out how to use common programming concepts like loops and conditionals so that you feel comfortable when starting out. There are lots of great resources online that you could look up.

Good luck!

I have observed the same behavior during test execution. It is strange that on production code works fine and fails only on tests.

Easy solution to make your tests happy is to add catch(angular.noop) to your promise mock. In case of example above it should looks like this:

resourceMock.get = function () {_x000D_
    var deferred = $q.defer();_x000D_
    deferred.reject(error);_x000D_
    return { $promise: deferred.promise.catch(angular.noop) };_x000D_
};

var arr = [];
while(mynumber--) {
    arr[mynumber] = String(mynumber+1);
}

Just add in the '0' in your select.

INSERT INTO table_name (a,b,c,d)
    SELECT
       other_table.a AS a,
       other_table.b AS b,
       other_table.c AS c,
       '0' AS d
    FROM other_table

Say you have a 32 bit integer, why not just move A into the first 16 bit half and B into the other?

def vec_pack(vec):
    return vec[0] + vec[1] * 65536;


def vec_unpack(number):
    return [number % 65536, number // 65536];

Other than this being as space efficient as possible and cheap to compute, a really cool side effect is that you can do vector math on the packed number.

a = vec_pack([2,4])
b = vec_pack([1,2])

print(vec_unpack(a+b)) # [3, 6] Vector addition
print(vec_unpack(a-b)) # [1, 2] Vector subtraction
print(vec_unpack(a*2)) # [4, 8] Scalar multiplication

To display the Json data using Robin Hartman code. You need to add, the below line.

The code he gave gives you Object, object. this code retrieves the data in a better way.

result.innerText =JSON.stringify(data);

I read this question and implemented the approach that has been stated regarding setting the response HTTP status code to 278 in order to avoid the browser transparently handling the redirects. Even though this worked, I was a little dissatisfied as it is a bit of a hack.

After more digging around, I ditched this approach and used JSON. In this case, all responses to AJAX requests have the status code 200 and the body of the response contains a JSON object that is constructed on the server. The JavaScript on the client can then use the JSON object to decide what it needs to do.

I had a similar problem to yours. I perform an AJAX request that has 2 possible responses: one that redirects the browser to a new page and one that replaces an existing HTML form on the current page with a new one. The jQuery code to do this looks something like:

$.ajax({
    type: "POST",
    url: reqUrl,
    data: reqBody,
    dataType: "json",
    success: function(data, textStatus) {
        if (data.redirect) {
            // data.redirect contains the string URL to redirect to
            window.location.href = data.redirect;
        } else {
            // data.form contains the HTML for the replacement form
            $("#myform").replaceWith(data.form);
        }
    }
});

The JSON object "data" is constructed on the server to have 2 members: data.redirect and data.form. I found this approach to be much better.

Try BinaryReader:

/// <summary>
/// Convert the Binary AnyFile to Byte[] format
/// </summary>
/// <param name="image"></param>
/// <returns></returns>
public static byte[] ConvertANYFileToBytes(HttpPostedFileBase image)
{
    byte[] imageBytes = null;
    BinaryReader reader = new BinaryReader(image.InputStream);
    imageBytes = reader.ReadBytes((int)image.ContentLength);
    return imageBytes;
}

You will find multiple different methods that people use and they each have there own place.

<?php if($first_condition): ?>
  /*$first_condition is true*/
<?php elseif ($second_condition): ?>
  /*$first_condition is false and $second_condition is true*/
<?php else: ?>
  /*$first_condition and $second_condition are false*/
<?php endif; ?>

If in your php.ini attribute short_open_tag = true (this is normally found on line 141 of the default php.ini file) you can replace your php open tag from <?php to <?. This is not advised as most live server environments have this turned off (including many CMS's like Drupal, WordPress and Joomla). I have already tested short hand open tags in Drupal and confirmed that it will break your site, so stick with <?php. short_open_tag is not on by default in all server configurations and must not be assumed as such when developing for unknown server configurations. Many hosting companies have short_open_tag turned off.

A quick search of short_open_tag in stackExchange shows 830 results. https://stackoverflow.com/search?q=short_open_tag That's a lot of people having problems with something they should just not play with.

with some server environments and applications, short hand php open tags will still crash your code even with short_open_tag set to true.

short_open_tag will be removed in PHP6 so don't use short hand tags.

all future PHP versions will be dropping short_open_tag

• http://www.askapache.com/php/shorthand-short_open_tag.html
• https://softwareengineering.stackexchange.com/questions/151661/is-it-bad-practice-to-use-tag-in-php

"It's been recommended for several years that you not use the short tag "short cut" and instead to use the full tag combination. With the wide spread use of XML and use of these tags by other languages, the server can become easily confused and end up parsing the wrong code in the wrong context. But because this short cut has been a feature for such a long time, it's currently still supported for backwards compatibility, but we recommend you don't use them." – Jelmer Sep 25 '12 at 9:00 php: "short_open_tag = On" not working

and

Normally you write PHP like so: . However if allow_short_tags directive is enabled you're able to use: . Also sort tags provides extra syntax: which is equal to .

Short tags might seem cool but they're not. They causes only more problems. Oh... and IIRC they'll be removed from PHP6. Crozin answered Aug 24 '10 at 22:12 php short_open_tag problem

and

To answer the why part, I'd quote Zend PHP 5 certification guide: "Short tags were, for a time, the standard in the PHP world; however, they do have the major drawback of conflicting with XML headers and, therefore, have somewhat fallen by the wayside." – Fluffy Apr 13 '11 at 14:40 Are PHP short tags acceptable to use?

You may also see people use the following example:

<?php if($first_condition){ ?>
  /*$first_condition is true*/
<?php }else if ($second_condition){ ?>
  /*$first_condition is false and $second_condition is true*/
<?php }else{ ?>
  /*$first_condition and $second_condition are false*/
<?php } ?>

This will work but it is highly frowned upon as it's not considered as legible and is not what you would use this format for. If you had a PHP file where you had a block of PHP code that didn't have embedded tags inside, then you would use the bracket format.

The following example shows when to use the bracket method

<?php
if($first_condition){
   /*$first_condition is true*/
}else if ($second_condition){
   /*$first_condition is false and $second_condition is true*/
}else{
   /*$first_condition and $second_condition are false*/
}
?>

If you're doing this code for yourself you can do what you like, but if your working with a team at a job it is advised to use the correct format for the correct circumstance. If you use brackets in embedded html/php scripts that is a good way to get fired, as no one will want to clean up your code after you. IT bosses will care about code legibility and college professors grade on legibility.

UPDATE

based on comments from duskwuff its still unclear if shorthand is discouraged (by the php standards) or not. I'll update this answer as I get more information. But based on many documents found on the web about shorthand being bad for portability. I would still personally not use it as it gives no advantage and you must rely on a setting being on that is not on for every web host.

From one of my other posts, getting a unixtimestamp:

$unixTimestamp = time();

Converting to mysql datetime format:

$mysqlTimestamp = date("Y-m-d H:i:s", $unixTimestamp);

Getting some mysql timestamp:

$mysqlTimestamp = '2013-01-10 12:13:37';

Converting it to a unixtimestamp:

$unixTimestamp = strtotime('2010-05-17 19:13:37');

...comparing it with one or a range of times, to see if the user entered a realistic time:

if($unixTimestamp > strtotime("1999-12-15") && $unixTimestamp < strtotime("2025-12-15"))
{...}

Unix timestamps are safer too. You can do the following to check if a url passed variable is valid, before checking (for example) the previous range check:

if(ctype_digit($_GET["UpdateTimestamp"]))
{...}

One more edge case and solution:

I added a boolean field, and at the same time added an @property referencing it, with the same name (doh). Commented the property and migration sees and adds the new field. Renamed the property and all is good.

We can use map function

print map(str, EmployeeList)

I had the same problem, only need to show shortdate (without the time), moreover it was needed to have multi-language settings, so depends of the language, show dd-mm-yyyy or mm-dd-yyyy.

Finally using DataFormatString="{0:d}, all works fine and show only the date with culture format.

HttpWebRequest webRequest = WebRequest.Create(uirTradeStream) as HttpWebRequest;

webRequest.Proxy = WebRequest.DefaultWebProxy;

webRequest.Proxy.Credentials = new NetworkCredential("user", "password");

It is successful.

Try adding a Reference to System.Configuration, you get some of the configuration namespace by referencing the System namespace, adding the reference to System.Configuration should allow you to access ConfigurationManager.

In Windows® systems you can simply try

pip3 list | findstr scikit

scikit-learn                  0.22.1

If you are on Anaconda try

conda list scikit

scikit-learn              0.22.1           py37h6288b17_0

And this can be used to find out the version of any package you have installed. For example

pip3 list | findstr numpy

numpy                         1.17.4
numpydoc                      0.9.2

Or if you want to look for more than one package at a time

pip3 list | findstr "scikit numpy"

numpy                         1.17.4
numpydoc                      0.9.2
scikit-learn                  0.22.1

Note the quote characters are required when searching for more than one word.

Take care.

I am not sure if/how browsers scale large icons, but The W3C suggests the following¹:

The format for the image you have chosen must be 16x16 pixels or 32x32 pixels, using either 8-bit or 24-bit colors. The format of the image must be one of PNG (a W3C standard), GIF, or ICO.

I like your question, regardless of whether it's off topic or not :P

An interesting aside; I've just completed a subject in my degree where we covered robotics and computer vision. Our project for the semester was incredibly similar to the one you describe.

We had to develop a robot that used an Xbox Kinect to detect coke bottles and cans on any orientation in a variety of lighting and environmental conditions. Our solution involved using a band pass filter on the Hue channel in combination with the hough circle transform. We were able to constrain the environment a bit (we could chose where and how to position the robot and Kinect sensor), otherwise we were going to use the SIFT or SURF transforms.

You can read about our approach on my blog post on the topic :)

Andrea solution is absolutely right, I will just write another implementation based on the same idea. If you took a look at the THREE.ImageUtils.loadTexture() source you will find it uses the javascript Image object. The $(window).load event is fired after all Images are loaded ! so at that event we can render our scene with the textures already loaded...

• CoffeeScript

  $(document).ready ->
  
      material = new THREE.MeshLambertMaterial(map: THREE.ImageUtils.loadTexture("crate.gif"))
  
      sphere   = new THREE.Mesh(new THREE.SphereGeometry(radius, segments, rings), material)
  
      $(window).load ->
          renderer.render scene, camera
  

• JavaScript

  $(document).ready(function() {
  
      material = new THREE.MeshLambertMaterial({ map: THREE.ImageUtils.loadTexture("crate.gif") });
  
      sphere = new THREE.Mesh(new THREE.SphereGeometry(radius, segments, rings), material);
  
      $(window).load(function() {
          renderer.render(scene, camera);
      });
  });
  

Thanks...

In general, one doesn't expand out log(a + b); you just deal with it as is. That said, there are occasionally circumstances where it makes sense to use the following identity:

log(a + b) = log(a * (1 + b/a)) = log a + log(1 + b/a)

(In fact, this identity is often used when implementing log in math libraries).

I am using Angular 6 with Bootstrap 4 and find this way works:

<div class="form-group row">
    <div class="col-md-2">
        <label for="currentPassword">Current Password:</label>
    </div>
    <div class="col-md-6">
        <input type="password" id="currentPassword">
    </div>
</div>

I have added few lines inside package.json:

"scripts": {
  ...
  "clean": "rmdir /s /q node_modules",
  "reinstall": "npm run clean && npm install",
  "rebuild": "npm run clean && npm install && rmdir /s /q dist && npm run build --prod",
  ...
}

If you want to clean only you can use this rimraf node_modules.

Lolz this is much better

    function isValidEmailAddress(emailAddress) {
        var pattern = new RegExp(/^([\w-\.]+@([\w-]+\.)+[\w-]{2,4})?$/);
        return pattern.test(emailAddress);
    };

This answer is similar to that provided by @tanemaki, but uses a lambda expression instead of scipy stats.

df = pd.DataFrame(np.random.randn(100, 3), columns=list('ABC'))

df[df.apply(lambda x: np.abs(x - x.mean()) / x.std() < 3).all(axis=1)]

To filter the DataFrame where only ONE column (e.g. 'B') is within three standard deviations:

df[((df.B - df.B.mean()) / df.B.std()).abs() < 3]

See here for how to apply this z-score on a rolling basis: Rolling Z-score applied to pandas dataframe

If you are working with redis and Java 8, you can take a look at JetCache:

@Cached(expire = 10, timeUnit = TimeUnit.MINUTES) User getUserById(long userId);

Another use is to split the implementation of different interfaces, e.g:

partial class MyClass : IF3
{
    // main implementation of MyClass
}


partial class MyClass : IF1
{
    // implementation of IF1
}

partial class MyClass : IF2
{
    // implementation of IF2
}

You can do that:

function formatAMPM(date) { // This is to display 12 hour format like you asked
  var hours = date.getHours();
  var minutes = date.getMinutes();
  var ampm = hours >= 12 ? 'pm' : 'am';
  hours = hours % 12;
  hours = hours ? hours : 12; // the hour '0' should be '12'
  minutes = minutes < 10 ? '0'+minutes : minutes;
  var strTime = hours + ':' + minutes + ' ' + ampm;
  return strTime;
}

var myDate = new Date();
var displayDate = myDate.getMonth()+ '/' +myDate.getDate()+ '/' +myDate.getFullYear()+ ' ' +formatAMPM(myDate);
console.log(displayDate);

Support, unfortunately, is brutal at best. Here's a post on the topic:

https://www.campaignmonitor.com/blog/email-marketing/2013/02/embedded-images-in-html-email/

It seems worth quoting PEP 0008 (Python's official style guide), since it comments upon this issue at modest length:

When the conditional part of an if -statement is long enough to require that it be written across multiple lines, it's worth noting that the combination of a two character keyword (i.e. if ), plus a single space, plus an opening parenthesis creates a natural 4-space indent for the subsequent lines of the multiline conditional. This can produce a visual conflict with the indented suite of code nested inside the if -statement, which would also naturally be indented to 4 spaces. This PEP takes no explicit position on how (or whether) to further visually distinguish such conditional lines from the nested suite inside the if -statement. Acceptable options in this situation include, but are not limited to:

# No extra indentation.
if (this_is_one_thing and
    that_is_another_thing):
    do_something()

# Add a comment, which will provide some distinction in editors
# supporting syntax highlighting.
if (this_is_one_thing and
    that_is_another_thing):
    # Since both conditions are true, we can frobnicate.
    do_something()

# Add some extra indentation on the conditional continuation line.
if (this_is_one_thing
        and that_is_another_thing):
    do_something()

Note the "not limited to" in the quote above; besides the approaches suggested in the style guide, some of the ones suggested in other answers to this question are acceptable too.

You can flatten the list and then store the values to a CommaSeparatedIntegerField. When you read back from the database, just group the values back into threes.

Disclaimer: according to database normalization theory, it is better not to store collections in single fields; instead you would be encouraged to store the values in those triplets in their own fields and link them via foreign keys. In the real world, though, sometimes that is too cumbersome/slow.

I use XAMPP. In C:\xampp\php\php.ini, the entry for openssl did not exist, so I added "extension=php_openssl.dll" on line 989, and composer worked.

Here is a solution for transposing a list of lists that is not necessarily square:

maxCol = len(l[0])
for row in l:
    rowLength = len(row)
    if rowLength > maxCol:
        maxCol = rowLength
lTrans = []
for colIndex in range(maxCol):
    lTrans.append([])
    for row in l:
        if colIndex < len(row):
            lTrans[colIndex].append(row[colIndex])

If you are working with Android's MediaStore database, here is how to store an image and then display it after it is saved.

on button click write this

 Intent in = new Intent(Intent.ACTION_PICK,
                    android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
            in.putExtra("crop", "true");
            in.putExtra("outputX", 100);
            in.putExtra("outputY", 100);
            in.putExtra("scale", true);
            in.putExtra("return-data", true);

            startActivityForResult(in, 1);

then do this in your activity

@Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        // TODO Auto-generated method stub
        super.onActivityResult(requestCode, resultCode, data);

        if (requestCode == 1 && resultCode == RESULT_OK && data != null) {

            Bitmap bmp = (Bitmap) data.getExtras().get("data");

            img.setImageBitmap(bmp);
            btnadd.requestFocus();

            ByteArrayOutputStream baos = new ByteArrayOutputStream();
            bmp.compress(Bitmap.CompressFormat.JPEG, 100, baos);
            byte[] b = baos.toByteArray();
            String encodedImageString = Base64.encodeToString(b, Base64.DEFAULT);

            byte[] bytarray = Base64.decode(encodedImageString, Base64.DEFAULT);
            Bitmap bmimage = BitmapFactory.decodeByteArray(bytarray, 0,
                    bytarray.length);

        }

    }

Here is how to create the desired outcome:

library(reshape2); library(tidyverse)
melt(outer(1:4, 1:4), varnames = c("X1", "X2")) %>%
ggplot() + 
  geom_tile(aes(X1, X2, fill = value)) + 
  scale_fill_continuous(guide = guide_legend()) +
  theme(legend.position="bottom",
        legend.spacing.x = unit(0, 'cm'))+
  guides(fill = guide_legend(label.position = "bottom"))

Edit: no need for these imperfect options anymore, but I'm leaving them here for reference.

Two imperfect options that don't give you exactly what you were asking for, but pretty close (will at least put the colours together).

library(reshape2); library(tidyverse)
df <- melt(outer(1:4, 1:4), varnames = c("X1", "X2"))
p1 <- ggplot(df, aes(X1, X2)) + geom_tile(aes(fill = value))
p1 + scale_fill_continuous(guide = guide_legend()) +
 theme(legend.position="bottom", legend.direction="vertical")

p1 + scale_fill_continuous(guide = "colorbar") + theme(legend.position="bottom")

You can use this simple plugin to add scrollUp and scrollDown to your jQuery

https://github.com/phpust/JQueryScrollDetector

var lastScrollTop = 0;
var action = "stopped";
var timeout = 100;
// Scroll end detector:
$.fn.scrollEnd = function(callback, timeout) {    
      $(this).scroll(function(){
        // get current scroll top 
        var st = $(this).scrollTop();
        var $this = $(this);
        // fix for page loads
        if (lastScrollTop !=0 )
        {
            // if it's scroll up
            if (st < lastScrollTop){
                action = "scrollUp";
            } 
            // else if it's scroll down
            else if (st > lastScrollTop){
                action = "scrollDown";
            }
        }
        // set the current scroll as last scroll top
        lastScrollTop = st;
        // check if scrollTimeout is set then clear it
        if ($this.data('scrollTimeout')) {
          clearTimeout($this.data('scrollTimeout'));
        }
        // wait until timeout done to overwrite scrolls output
        $this.data('scrollTimeout', setTimeout(callback,timeout));
    });
};

$(window).scrollEnd(function(){
    if(action!="stopped"){
        //call the event listener attached to obj.
        $(document).trigger(action); 
    }
}, timeout);

That won't work if the string contains more than one match... try this:

echo "/x/y/z/x" | awk '{ gsub("/", "_") ; system( "echo "  $0) }'

or better (if the echo isn't a placeholder for something else):

echo "/x/y/z/x" | awk '{ gsub("/", "_") ; print $0 }'

In your case you want to make a copy of the value before changing it:

echo "/x/y/z/x" | awk '{ c=$0; gsub("/", "_", c) ; system( "echo " $0 " " c )}'

On Laravel 5.5, the cleanest way to do this is:

Theme::with('user:userid,name,address')->get()

You add a colon and the fields you wish to select separated by a comma and without a space between them.

The best to get rid of this is to keep activity reference when onAttach is called and use the activity reference wherever needed, for e.g.

@Override
public void onAttach(Context context) {
    super.onAttach(activity);
    mContext = context;
}

@Override
public void onDetach() {
    super.onDetach();
    mContext = null;
}

Try this:

Insert Into table2
Select * from table1

Adding another answer to this question because I needed precisely what @derek was asking for and I'd already gotten a bit further before seeing the answers here. Specifically, I needed CSS that could also account for the case with exactly two list items, where the comma is NOT desired. As an example, some authorship bylines I wanted to produce would look like the following:

One author: By Adam Smith.

Two authors: By Adam Smith and Jane Doe.

Three authors: By Adam Smith, Jane Doe, and Frank Underwood.

The solutions already given here work for one author and for 3 or more authors, but neglect to account for the two author case—where the "Oxford Comma" style (also known as "Harvard Comma" style in some parts) doesn't apply - ie, there should be no comma before the conjunction.

After an afternoon of tinkering, I had come up with the following:

<html>
 <head>
  <style type="text/css">
    .byline-list {
      list-style: none;
      padding: 0;
      margin: 0;
    }
    .byline-list > li {
      display: inline;
      padding: 0;
      margin: 0;
    }
    .byline-list > li::before {
      content: ", ";
    }
    .byline-list > li:last-child::before {
      content: ", and ";
    }
    .byline-list > li:first-child + li:last-child::before {
      content: " and ";
    }
    .byline-list > li:first-child::before {
      content: "By ";
    }
    .byline-list > li:last-child::after {
      content: ".";
    }
  </style>
 </head>
 <body>
  <ul class="byline-list">
   <li>Adam Smith</li>
  </ul>
  <ul class="byline-list">
   <li>Adam Smith</li><li>Jane Doe</li>
  </ul>
  <ul class="byline-list">
   <li>Adam Smith</li><li>Jane Doe</li><li>Frank Underwood</li>
  </ul>
 </body>
</html>

It displays the bylines as I've got them above.

In the end, I also had to get rid of any whitespace between li elements, in order to get around an annoyance: the inline-block property would otherwise leave a space before each comma. There's probably an alternative decent hack for it but that isn't the subject of this question so I'll leave that for someone else to answer.

Fiddle here: http://jsfiddle.net/5REP2/

require(ggplot2)
require(nlme)

set.seed(101)
mp <-data.frame(year=1990:2010)
N <- nrow(mp)

mp <- within(mp,
         {
             wav <- rnorm(N)*cos(2*pi*year)+rnorm(N)*sin(2*pi*year)+5
             wow <- rnorm(N)*wav+rnorm(N)*wav^3
         })

m01 <- gls(wow~poly(wav,3), data=mp, correlation = corARMA(p=1))

Get fitted values (the same as m01$fitted)

fit <- predict(m01)

Normally we could use something like predict(...,se.fit=TRUE) to get the confidence intervals on the prediction, but gls doesn't provide this capability. We use a recipe similar to the one shown at http://glmm.wikidot.com/faq :

V <- vcov(m01)
X <- model.matrix(~poly(wav,3),data=mp)
se.fit <- sqrt(diag(X %*% V %*% t(X)))

Put together a "prediction frame":

predframe <- with(mp,data.frame(year,wav,
                                wow=fit,lwr=fit-1.96*se.fit,upr=fit+1.96*se.fit))

Now plot with geom_ribbon

(p1 <- ggplot(mp, aes(year, wow))+
    geom_point()+
    geom_line(data=predframe)+
    geom_ribbon(data=predframe,aes(ymin=lwr,ymax=upr),alpha=0.3))

It's easier to see that we got the right answer if we plot against wav rather than year:

(p2 <- ggplot(mp, aes(wav, wow))+
    geom_point()+
    geom_line(data=predframe)+
    geom_ribbon(data=predframe,aes(ymin=lwr,ymax=upr),alpha=0.3))

It would be nice to do the predictions with more resolution, but it's a little tricky to do this with the results of poly() fits -- see ?makepredictcall.

You should use "merge a range of revision".

To merge changes from the trunk to a branch, inside the branch working copy choose "merge range of revisions" and enter the trunk URL and the start and end revisions to merge.

The same in the opposite way to merge a branch in the trunk.

In your function definition you're constraining sets a and b to the same type. You can also write

public <X,Y> void myFunction(Set<X> s1, Set<Y> s2){...}

Those files are created and used by Android Studio editor.

You don't need to check in those files to version control.

Git uses .gitignore file, that contains list of files and directories, to know the list of files and directories that don't need to be checked in.

Android studio automatically creates .gitingnore files listing all files and directories which don't need to be checked in to any version control.

I prefer to use an IF statement in the FOR loop that checks to make sure the current iteration isn't the last value in the array. If not, add a comma

$fruit = array("apple", "banana", "pear", "grape");

for($i = 0; $i < count($fruit); $i++){
    echo "$fruit[$i]";
    if($i < (count($fruit) -1)){
      echo ", ";
    }
}

the ideal way is to

{{ something|safe }}

than completely turning off auto escaping.

Try this

HTML

<select class="form-control"name="country">
<option class="servce_pro_disabled">Select Country</option>
<option class="servce_pro_disabled" value="Aruba" id="cl_country_option">Aruba</option>
</select>

CSS

.form-control option:first-child {
    display: none;
}

I had the same problem and I solved in a slightly different way from the others. I am using angular 1.4.4.

In my case, I have a shell template that creates a CSS Bootstrap panel:

<div class="class-container panel panel-info">
    <div class="panel-heading">
        <h3 class="panel-title">{{title}} </h3>
    </div>
    <div class="panel-body">
        <sp-panel-body panelbodytpl="{{panelbodytpl}}"></sp-panel-body>
    </div>
</div>

I want to include panel body templates depending on the route.

    angular.module('MyApp')
    .directive('spPanelBody', ['$compile', function($compile){
        return {
            restrict        : 'E',
            scope : true,
            link: function (scope, element, attrs) {
                scope.data = angular.fromJson(scope.data);
                element.append($compile('<ng-include src="\'' + scope.panelbodytpl + '\'"></ng-include>')(scope));
            }
        }
    }]);

I then have the following template included when the route is #/students:

<div class="students-wrapper">
    <div ng-controller="StudentsIndexController as studentCtrl" class="row">
        <div ng-repeat="student in studentCtrl.students" class="col-sm-6 col-md-4 col-lg-3">
            <sp-panel 
            title="{{student.firstName}} {{student.middleName}} {{student.lastName}}"
            panelbodytpl="{{'/student/panel-body.html'}}"
            data="{{student}}"
            ></sp-panel>
        </div>
    </div>
</div>

The panel-body.html template as follows:

Date of Birth: {{data.dob * 1000 | date : 'dd MMM yyyy'}}

Sample data in the case someone wants to have a go:

var student = {
    'id'            : 1,
    'firstName'     : 'John',
    'middleName'    : '',
    'lastName'      : 'Smith',
    'dob'           : 1130799600,
    'current-class' : 5
}

Now in Python >= 3.3 you can just call the timestamp() method to get the timestamp as a float.

import datetime
current_time = datetime.datetime.now(datetime.timezone.utc)
unix_timestamp = current_time.timestamp() # works if Python >= 3.3

unix_timestamp_plus_5_min = unix_timestamp + (5 * 60)  # 5 min * 60 seconds

A minor improvement on a variant:

Storage.prototype.setObject = function(key, value) {
    this.setItem(key, JSON.stringify(value));
}

Storage.prototype.getObject = function(key) {
    var value = this.getItem(key);
    return value && JSON.parse(value);
}

Because of short-circuit evaluation, getObject() will immediately return null if key is not in Storage. It also will not throw a SyntaxError exception if value is "" (the empty string; JSON.parse() cannot handle that).

In Java, when you write:

Object objectA = new Object();
Object objectB = objectA;

objectA and objectB are the same and point to the same reference. Changing one will change the other. So if you change the state of objectA (not its reference) objectB will reflect that change too.

However, if you write:

objectA = new Object()

Then objectB is still pointing to the first object you created (original objectA) while objectA is now pointing to a new Object.

Apart from the information given by David M. Lloyd one could add that the mechanism that allows this is called target typing.

The idea is that the type the compiler assigns to a lambda expressions or a method references does not depend only on the expression itself, but also on where it is used.

The target of an expression is the variable to which its result is assigned or the parameter to which its result is passed.

Lambda expressions and method references are assigned a type which matches the type of their target, if such a type can be found.

See the Type Inference section in the Java Tutorial for more information.
