I solved this issue by doing like that:

insert into my_table(my_field_0, ..., my_field_n) values(my_value_0, ..., my_value_n)

The great thing about yyyy-mm-dd date format is that there is no need to extract month() and year(), you can do comparisons directly on strings:

SELECT *
  FROM your_table
  WHERE your_date_column >= '2010-09-01' AND your_date_column <= '2013-08-31';

@sarath how to overwrite the file if i want to run another select * command from a different table and write to same file ?

INSERT OVERWRITE LOCAL DIRECTORY '/home/training/mydata/outputs' SELECT expl , count(expl) as total
FROM ( SELECT explode(splits) as expl FROM ( SELECT split(words,' ') as splits FROM wordcount ) t2 ) t3 GROUP BY expl ;

This is an example to sarath's question

the above is a word count job stored in outputs file which is in local directory :)

nvl(value,defaultvalue) as Columnname

will set the missing values to defaultvalue specified

AFAIK you must reformat your String in ISO format to be able to cast it as a Date:

cast(concat(substr(STR_DMY,7,4), '-',
            substr(STR_DMY,1,2), '-',
            substr(STR_DMY,4,2)
           )
     as date
     ) as DT

To display a Date as a String with specific format, then it's the other way around, unless you have Hive 1.2+ and can use date_format()

=> did you check the documentation by the way?

As of Hive version 0.14.0: INSERT...VALUES, UPDATE, and DELETE are now available with full ACID support.

INSERT ... VALUES Syntax:

INSERT INTO TABLE tablename [PARTITION (partcol1[=val1], partcol2[=val2] ...)] VALUES values_row [, values_row ...]

Where values_row is: ( value [, value ...] ) where a value is either null or any valid SQL literal

UPDATE Syntax:

UPDATE tablename SET column = value [, column = value ...] [WHERE expression]

DELETE Syntax:

DELETE FROM tablename [WHERE expression]

Additionally, from the Hive Transactions doc:

If a table is to be used in ACID writes (insert, update, delete) then the table property "transactional" must be set on that table, starting with Hive 0.14.0. Without this value, inserts will be done in the old style; updates and deletes will be prohibited.

If you look at the hive-site.xml file you will see something like this

<property>
   <name>hive.metastore.warehouse.dir</name>
   <value>/usr/hive/warehouse </value>
   <description>location of the warehouse directory</description>
 </property>

/usr/hive/warehouse is the default location for all managed tables. External tables may be stored at a different location.

describe formatted <table_name> is the hive shell command which can be use more generally to find the location of data pertaining to a hive table.

Here's one way. The inner query gets the max date for each id. Then you can join that back to your main table to get the rows that match.

select
*
from
<your table>
inner join 
(select id, max(<date col> as max_date) m
where yourtable.id = m.id
and yourtable.datecolumn = m.max_date)

CLI has some limit when ouput is displayed. I suggest to export output into local file:

$hive -e 'show partitions table;' > partitions

Tried in Hive and got the below output

table1

1,wqe,chennai,india

2,stu,salem,india

3,mia,bangalore,india

4,yepie,newyork,USA

table2

1,wqe,chennai,india

2,stu,salem,india

3,mia,bangalore,india

5,chapie,Los angels,USA

Inner Join

SELECT * FROM table1 INNER JOIN table2 ON (table1.id = table2.id);

1 wqe chennai india 1 wqe chennai india

2 stu salem india 2 stu salem india

3 mia bangalore india 3 mia bangalore india

Left Join

SELECT * FROM table1 LEFT JOIN table2 ON (table1.id = table2.id);

1 wqe chennai india 1 wqe chennai india

2 stu salem india 2 stu salem india

3 mia bangalore india 3 mia bangalore india

4 yepie newyork USA NULL NULL NULL NULL

Left Semi Join

SELECT * FROM table1 LEFT SEMI JOIN table2 ON (table1.id = table2.id);

1 wqe chennai india

2 stu salem india

3 mia bangalore india

note: Only records in left table are displayed whereas for Left Join both the table records displayed

For a Comparison Between Hadoop Vs Cassandra/HBase read this post.

Basically HBase enables really fast read and writes with scalability. How fast and scalable? Facebook uses it to manage its user statuses, photos, chat messages etc. HBase is so fast sometimes stacks have been developed by Facebook to use HBase as the data store for Hive itself.

Where As Hive is more like a Data Warehousing solution. You can use a syntax similar to SQL to query Hive contents which results in a Map Reduce job. Not ideal for fast, transactional systems.

Just a clarification on the answer given by Bkkbrad.

I tried this suggestion and it did not work for me.

For example,

split('aa|bb','\\|')

produced:

["","a","a","|","b","b",""]

But,

split('aa|bb','[|]')

produced the desired result:

["aa","bb"]

Including the metacharacter '|' inside the square brackets causes it to be interpreted literally, as intended, rather than as a metacharacter.

For elaboration of this behaviour of regexp, see: http://www.regular-expressions.info/charclass.html

Hive Partitioning:

Partition divides large amount of data into multiple slices based on value of a table column(s).

Assume that you are storing information of people in entire world spread across 196+ countries spanning around 500 crores of entries. If you want to query people from a particular country (Vatican city), in absence of partitioning, you have to scan all 500 crores of entries even to fetch thousand entries of a country. If you partition the table based on country, you can fine tune querying process by just checking the data for only one country partition. Hive partition creates a separate directory for a column(s) value.

Pros:

1. Distribute execution load horizontally
2. Faster execution of queries in case of partition with low volume of data. e.g. Get the population from "Vatican city" returns very fast instead of searching entire population of world.

Cons:

1. Possibility of too many small partition creations - too many directories.
2. Effective for low volume data for a given partition. But some queries like group by on high volume of data still take long time to execute. e.g. Grouping of population of China will take long time compared to grouping of population in Vatican city. Partition is not solving responsiveness problem in case of data skewing towards a particular partition value.

Hive Bucketing:

Bucketing decomposes data into more manageable or equal parts.

With partitioning, there is a possibility that you can create multiple small partitions based on column values. If you go for bucketing, you are restricting number of buckets to store the data. This number is defined during table creation scripts.

Pros

1. Due to equal volumes of data in each partition, joins at Map side will be quicker.
2. Faster query response like partitioning

Cons

1. You can define number of buckets during table creation but loading of equal volume of data has to be done manually by programmers.

Firstly — I don't think column1 is not NULL or column1 <> '' makes very much sense. Maybe you meant to write column1 is not NULL and column1 <> '' (AND instead of OR)?

Secondly — because of Hive's "schema on read" approach to table definitions, invalid values will be converted to NULL when you read from them. So, for example, if table1.column1 is of type STRING and table2.column1 is of type INT, then I don't think that table1.column1 IS NOT NULL is enough to guarantee that table2.column1 IS NOT NULL. (I'm not sure about this, though.)

You can store the output of another query in a variable and latter you can use the same in your code:

set var=select count(*) from My_table;
${hiveconf:var};

Below is the end-to-end solution that I use to export Hive table data to HDFS as a single named CSV file with a header.
(it is unfortunate that it's not possible to do with one HQL statement)
It consists of several commands, but it's quite intuitive, I think, and it does not rely on the internal representation of Hive tables, which may change from time to time.
Replace "DIRECTORY" with "LOCAL DIRECTORY" if you want to export the data to a local filesystem versus HDFS.

# cleanup the existing target HDFS directory, if it exists
sudo -u hdfs hdfs dfs -rm -f -r /tmp/data/my_exported_table_name/*

# export the data using Beeline CLI (it will create a data file with a surrogate name in the target HDFS directory)
beeline -u jdbc:hive2://my_hostname:10000 -n hive -e "INSERT OVERWRITE DIRECTORY '/tmp/data/my_exported_table_name' ROW FORMAT DELIMITED FIELDS TERMINATED BY ',' SELECT * FROM my_exported_table_name"

# set the owner of the target HDFS directory to whatever UID you'll be using to run the subsequent commands (root in this case)
sudo -u hdfs hdfs dfs -chown -R root:hdfs /tmp/data/my_exported_table_name

# write the CSV header record to a separate file (make sure that its name is higher in the sort order than for the data file in the target HDFS directory)
# also, obviously, make sure that the number and the order of fields is the same as in the data file
echo 'field_name_1,field_name_2,field_name_3,field_name_4,field_name_5' | hadoop fs -put - /tmp/data/my_exported_table_name/.header.csv

# concatenate all (2) files in the target HDFS directory into the final CSV data file with a header
# (this is where the sort order of the file names is important)
hadoop fs -cat /tmp/data/my_exported_table_name/* | hadoop fs -put - /tmp/data/my_exported_table_name/my_exported_table_name.csv

# give the permissions for the exported data to other users as necessary
sudo -u hdfs hdfs dfs -chmod -R 777 /tmp/data/hive_extr/drivers

You can use below approach. With this, You don't need to create temp table OR txt/csv file for further select and load respectively.

INSERT INTO TABLE tablename SELECT value1,value2 FROM tempTable_with_atleast_one_records LIMIT 1.

Where tempTable_with_atleast_one_records is any table with atleast one record.

But problem with this approach is that If you have INSERT statement which inserts multiple rows like below one.

INSERT INTO yourTable values (1 , 'value1') , (2 , 'value2') , (3 , 'value3') ;

Then, You need to have separate INSERT hive statement for each rows. See below.

INSERT INTO TABLE yourTable SELECT 1 , 'value1' FROM tempTable_with_atleast_one_records LIMIT 1;
INSERT INTO TABLE yourTable SELECT 2 , 'value2' FROM tempTable_with_atleast_one_records LIMIT 1;
INSERT INTO TABLE yourTable SELECT 3 , 'value3' FROM tempTable_with_atleast_one_records LIMIT 1;

If you want a CSV file then you can modify Lukas' solutions as follows (assuming you are on a linux box):

hive -e 'select books from table' | sed 's/[[:space:]]\+/,/g' > /home/lvermeer/temp.csv

Describe Formatted/Extended will show the data definition of the table in hive

hive> describe Formatted dbname.tablename;

The functions current_date and current_timestamp are now available in Hive 1.2.0 and higher, which makes the code a lot cleaner.

To Truncate:

hive -e "TRUNCATE TABLE IF EXISTS $tablename"

To Drop:

hive -e "Drop TABLE IF EXISTS $tablename"

An alternative to 'LOAD DATA' is available in which the data will not be moved from your existing source location to hive data warehouse location.

You can use ALTER TABLE command with 'LOCATION' option. Here is below required command

ALTER TABLE table_name ADD PARTITION (date_col='2017-02-07') LOCATION 'hdfs/path/to/location/'

The only condition here is, the location should be a directory instead of file.

Hope this will solve the problem.

If the value is between –2147483648 and 2147483647, cast(string_filed as int) will work. else cast(string_filed as bigint) will work

    hive> select cast('2147483647' as int);
    OK
    2147483647
    
    hive> select cast('2147483648' as int);
    OK
    NULL
    
    hive> select cast('2147483648' as bigint);
    OK
    2147483648

I removed the _SUCCESS file from the EMR output path in S3 and it worked fine.

Try to use this with single quotes in data:

insert into table test_hive values ('1','puneet');

You cannot add a column with a default value in Hive. You have the right syntax for adding the column ALTER TABLE test1 ADD COLUMNS (access_count1 int);, you just need to get rid of default sum(max_count). No changes to that files backing your table will happen as a result of adding the column. Hive handles the "missing" data by interpreting NULL as the value for every cell in that column.

So now your have the problem of needing to populate the column. Unfortunately in Hive you essentially need to rewrite the whole table, this time with the column populated. It may be easier to rerun your original query with the new column. Or you could add the column to the table you have now, then select all of its columns plus value for the new column.

You also have the option to always COALESCE the column to your desired default and leave it NULL for now. This option fails when you want NULL to have a meaning distinct from your desired default. It also requires you to depend on always remembering to COALESCE.

If you are very confident in your abilities to deal with the files backing Hive, you could also directly alter them to add your default. In general I would recommend against this because most of the time it will be slower and more dangerous. There might be some case where it makes sense though, so I've included this option for completeness.

In the comments @libjack mentioned a point which is really important. I would like to illustrate more into it. First, we can check what are the columns of our table by describe <table_name>; command.

there is a double-column called _c1 and such columns are created by the hive itself when we moving data from one table to another. To address these columns we need to write it inside backticks

`_c1`

Finally, the ALTER command will be,

ALTER TABLE <table_namr> CHANGE `<system_genarated_column_name>` <new_column_name> <data_type>;

This should certainly work:

hive --version

The problem is that Hive doesn't handle quoted texts. You either need to pre-process the data by changing the delimiter between the fields (e.g: with a Hadoop-streaming job) or you can also give a try to use a custom CSV SerDe which uses OpenCSV to parse the files.

Let's say we have an external table called employee

hive> SHOW CREATE TABLE employee;
OK
CREATE EXTERNAL TABLE employee(
  id string,
  fname string,
  lname string, 
  salary double)
ROW FORMAT SERDE
  'org.apache.hadoop.hive.serde2.lazy.LazySimpleSerDe'
WITH SERDEPROPERTIES (
  'colelction.delim'=':',
  'field.delim'=',',
  'line.delim'='\n',
  'serialization.format'=',')
STORED AS INPUTFORMAT
  'org.apache.hadoop.mapred.TextInputFormat'
OUTPUTFORMAT
  'org.apache.hadoop.hive.ql.io.HiveIgnoreKeyTextOutputFormat'
LOCATION
  'maprfs:/user/hadoop/data/employee'
TBLPROPERTIES (
  'COLUMN_STATS_ACCURATE'='false',
  'numFiles'='0',
  'numRows'='-1',
  'rawDataSize'='-1',
  'totalSize'='0',
  'transient_lastDdlTime'='1487884795')

1. To create a person table like employee

   CREATE TABLE person LIKE employee;

2. To create a person external table like employee

   CREATE TABLE person LIKE employee LOCATION 'maprfs:/user/hadoop/data/person';

3. then use DESC person; to see the newly created table schema.

Alter table table_name drop partition (partition_name);

Consider this scenario which best suits for External Table:

A MapReduce (MR) job filters a huge log file to spit out n sub log files (e.g. each sub log file contains a specific message type log) and the output i.e n sub log files are stored in hdfs.

These log files are to be loaded into Hive tables for performing further analytic, in this scenario I would recommend an External Table(s), because the actual log files are generated and owned by an external process i.e. a MR job besides you can avoid an additional step of loading each generated log file into respective Hive table as well.

in the 'default' directory if you have not specifically mentioned your location.

you can use describe and describe extended to know about the table structure.

regexp_replace UDF performs my task. Below is the definition and usage from apache Wiki.

regexp_replace(string INITIAL_STRING, string PATTERN, string REPLACEMENT):

This returns the string resulting from replacing all substrings in INITIAL_STRING that match the java regular expression syntax defined in PATTERN with instances of REPLACEMENT,

e.g.: regexp_replace("foobar", "oo|ar", "") returns fb

You can use hive library,for that you want to import hive Class from hive import ThriftHive

Try This example:

import sys

from hive import ThriftHive
from hive.ttypes import HiveServerException

from thrift import Thrift
from thrift.transport import TSocket
from thrift.transport import TTransport
from thrift.protocol import TBinaryProtocol

try:
  transport = TSocket.TSocket('localhost', 10000)
  transport = TTransport.TBufferedTransport(transport)
  protocol = TBinaryProtocol.TBinaryProtocol(transport)
  client = ThriftHive.Client(protocol)
  transport.open()
  client.execute("CREATE TABLE r(a STRING, b INT, c DOUBLE)")
  client.execute("LOAD TABLE LOCAL INPATH '/path' INTO TABLE r")
  client.execute("SELECT * FROM r")
  while (1):
    row = client.fetchOne()
    if (row == None):
       break
    print row

  client.execute("SELECT * FROM r")
  print client.fetchAll()
  transport.close()
except Thrift.TException, tx:
  print '%s' % (tx.message)

While you have your answer from Daniel, here are some customizations possible using OpenCSVSerde:

CREATE EXTERNAL TABLE `mydb`.`mytable`(
    `product_name` string,
    `brand_id` string,
    `brand` string,
    `color` string,
    `description` string,
    `sale_price` string)
PARTITIONED BY (
    `seller_id` string)
ROW FORMAT SERDE
    'org.apache.hadoop.hive.serde2.OpenCSVSerde'
WITH SERDEPROPERTIES (
    'separatorChar' = '\t',
    'quoteChar' = '"',
    'escapeChar' = '\\')
STORED AS INPUTFORMAT
    'org.apache.hadoop.mapred.TextInputFormat'
OUTPUTFORMAT
    'org.apache.hadoop.hive.ql.io.HiveIgnoreKeyTextOutputFormat'
LOCATION
    'hdfs://namenode.com:port/data/mydb/mytable'
TBLPROPERTIES (
    'serialization.null.format' = '',
    'skip.header.line.count' = '1')

With this, you have total control over the separator, quote character, escape character, null handling and header handling.

Look here and here.

Hive apparently supports INSERT...VALUES starting in Hive 0.14.

Please see the section 'Inserting into tables from SQL' at: https://cwiki.apache.org/confluence/display/Hive/LanguageManual+DML

You may try this, Following are few examples on how files are generated. Tool -- https://sourceforge.net/projects/csvtohive/?source=directory

1. Select a CSV file using Browse and set hadoop root directory ex: /user/bigdataproject/

2. Tool Generates Hadoop script with all csv files and following is a sample of generated Hadoop script to insert csv into Hadoop

   #!/bin/bash -v
   
   hadoop fs -put ./AllstarFull.csv /user/bigdataproject/AllstarFull.csv
   hive -f ./AllstarFull.hive

You can create an in-memory temporary table and store them in hive table using sqlContext.

Lets say your data frame is myDf. You can create one temporary table using,

myDf.createOrReplaceTempView("mytempTable") 

Then you can use a simple hive statement to create table and dump the data from your temp table.

sqlContext.sql("create table mytable as select * from mytempTable");

Best way to do this is setting the below property:

set hive.cli.print.header=true;
set hive.resultset.use.unique.column.names=false;

The withColumn function in pyspark enables you to make a new variable with conditions, add in the when and otherwise functions and you have a properly working if then else structure. For all of this you would need to import the sparksql functions, as you will see that the following bit of code will not work without the col() function. In the first bit, we declare a new column -'new column', and then give the condition enclosed in when function (i.e. fruit1==fruit2) then give 1 if the condition is true, if untrue the control goes to the otherwise which then takes care of the second condition (fruit1 or fruit2 is Null) with the isNull() function and if true 3 is returned and if false, the otherwise is checked again giving 0 as the answer.

from pyspark.sql import functions as F
df=df.withColumn('new_column', 
    F.when(F.col('fruit1')==F.col('fruit2'), 1)
    .otherwise(F.when((F.col('fruit1').isNull()) | (F.col('fruit2').isNull()), 3))
    .otherwise(0))

datediff(to_date(String timestamp), to_date(String timestamp))

For example:

SELECT datediff(to_date('2019-08-03'), to_date('2019-08-01')) <= 2;

You cannot directly create a table stored as a sequence file and insert text into it. You must do this:

1. Create a table stored as text
2. Insert the text file into the text table
3. Do a CTAS to create the table stored as a sequence file.
4. Drop the text table if desired

Example:

CREATE TABLE test_txt(field1 int, field2 string)
ROW FORMAT DELIMITED FIELDS TERMINATED BY '\t';

LOAD DATA INPATH '/path/to/file.tsv' INTO TABLE test_txt;

CREATE TABLE test STORED AS SEQUENCEFILE
AS SELECT * FROM test_txt;

DROP TABLE test_txt;

Yes, here you can use LIMIT.

You can try it by the below query:

SELECT * FROM employee_list SORT BY salary DESC LIMIT 2

What HIVE can do which is not possible in PIG?

Partitioning can be done using HIVE but not in PIG, it is a way of bypassing the output.

What PIG can do which is not possible in HIVE?

Positional referencing - Even when you dont have field names, we can reference using the position like $0 - for first field, $1 for second and so on.

And another fundamental difference is, PIG doesn't need a schema to write the values but HIVE does need a schema.

You can connect from any external application to HIVE using JDBC and others but not with PIG.

Note: Both runs on top of HDFS (hadoop distributed file system) and the statements are converted to Map Reduce programs.

In the middle of the stack trace, lost in the "reflection" junk, you can find the root cause:

The specified datastore driver ("com.mysql.jdbc.Driver") was not found in the CLASSPATH. Please check your CLASSPATH specification, and the name of the driver.

use SELECT...INTO

The SELECT INTO statement creates a new table and populates it with the result set of the SELECT statement. SELECT INTO can be used to combine data from several tables or views into one table. It can also be used to create a new table that contains data selected from a linked server.

Example,

SELECT col1, col2 INTO #a -- <<== creates temporary table
FROM   tablename

• Inserting Rows by Using SELECT INTO

Standard Syntax,

SELECT  col1, ....., col@      -- <<== select as many columns as you want
        INTO [New tableName]
FROM    [Source Table Name]

It's possible to use:

res.redirect('your/404/path.html');

Use this snippet:

@echo off
echo something
echo.
echo press enter to exit
pause >nul
exit

To run your_command as a subprocess in a different directory, pass cwd parameter, as suggested in @wim's answer:

import subprocess

subprocess.check_call(['your_command', 'arg 1', 'arg 2'], cwd=working_dir)

A child process can't change its parent's working directory (normally). Running cd .. in a child shell process using subprocess won't change your parent Python script's working directory i.e., the code example in @glglgl's answer is wrong. cd is a shell builtin (not a separate executable), it can change the directory only in the same process.

Instead of using

int * p;
p = {1,2,3};

we can use

int * p;
p =(int[3]){1,2,3};

$host is a variable of the Core module.

$host

This variable is equal to line Host in the header of request or name of the server processing the request if the Host header is not available.

This variable may have a different value from $http_host in such cases: 1) when the Host input header is absent or has an empty value, $host equals to the value of server_name directive; 2)when the value of Host contains port number, $host doesn't include that port number. $host's value is always lowercase since 0.8.17.

$http_host is also a variable of the same module but you won't find it with that name because it is defined generically as $http_HEADER (ref).

$http_HEADER

The value of the HTTP request header HEADER when converted to lowercase and with 'dashes' converted to 'underscores', e.g. $http_user_agent, $http_referer...;

Summarizing:

• $http_host equals always the HTTP_HOST request header.
• $host equals $http_host, lowercase and without the port number (if present), except when HTTP_HOST is absent or is an empty value. In that case, $host equals the value of the server_name directive of the server which processed the request.

I think this should work:

#include <time.h>

clock_t start = clock(), diff;
ProcessIntenseFunction();
diff = clock() - start;

int msec = diff * 1000 / CLOCKS_PER_SEC;
printf("Time taken %d seconds %d milliseconds", msec/1000, msec%1000);

Sometimes it's more simple to implement a copy constructor:

public MyObject (MyObject toClone) {
}

It saves you the trouble of handling CloneNotSupportedException, works with final fields and you don't have to worry about the type to return.

This is the best option to cast/convert list of generic object to list of string.

object valueList;
List<string> list = ((IList)valueList).Cast<object>().Select(o => o.ToString()).ToList();

From Ubuntu 18.4 (Bionic Beaver) it is advisable to use apt instead of apt-get since it has much better structural form.

sudo apt install libxml2-dev libxslt1-dev python-dev

If you're happy with a possibly older version of lxml altogether though, you could try

sudo apt install python-lxml

Tried printf(1)?

printf "%x\n" 34
22

There are probably ways of doing that with builtin functions in all shells but it would be less portable. I've not checked the POSIX sh specs to see whether it has such capabilities.

Here's a bit more detail to expand on Hooked's answer. When I first read that answer, I missed the instruction to call clf() instead of creating a new figure. clf() on its own doesn't help if you then go and create another figure.

Here's a trivial example that causes the warning:

from matplotlib import pyplot as plt, patches
import os


def main():
    path = 'figures'
    for i in range(21):
        _fig, ax = plt.subplots()
        x = range(3*i)
        y = [n*n for n in x]
        ax.add_patch(patches.Rectangle(xy=(i, 1), width=i, height=10))
        plt.step(x, y, linewidth=2, where='mid')
        figname = 'fig_{}.png'.format(i)
        dest = os.path.join(path, figname)
        plt.savefig(dest)  # write image to file
        plt.clf()
    print('Done.')

main()

To avoid the warning, I have to pull the call to subplots() outside the loop. In order to keep seeing the rectangles, I need to switch clf() to cla(). That clears the axis without removing the axis itself.

from matplotlib import pyplot as plt, patches
import os


def main():
    path = 'figures'
    _fig, ax = plt.subplots()
    for i in range(21):
        x = range(3*i)
        y = [n*n for n in x]
        ax.add_patch(patches.Rectangle(xy=(i, 1), width=i, height=10))
        plt.step(x, y, linewidth=2, where='mid')
        figname = 'fig_{}.png'.format(i)
        dest = os.path.join(path, figname)
        plt.savefig(dest)  # write image to file
        plt.cla()
    print('Done.')

main()

If you're generating plots in batches, you might have to use both cla() and close(). I ran into a problem where a batch could have more than 20 plots without complaining, but it would complain after 20 batches. I fixed that by using cla() after each plot, and close() after each batch.

from matplotlib import pyplot as plt, patches
import os


def main():
    for i in range(21):
        print('Batch {}'.format(i))
        make_plots('figures')
    print('Done.')


def make_plots(path):
    fig, ax = plt.subplots()
    for i in range(21):
        x = range(3 * i)
        y = [n * n for n in x]
        ax.add_patch(patches.Rectangle(xy=(i, 1), width=i, height=10))
        plt.step(x, y, linewidth=2, where='mid')
        figname = 'fig_{}.png'.format(i)
        dest = os.path.join(path, figname)
        plt.savefig(dest)  # write image to file
        plt.cla()
    plt.close(fig)


main()

I measured the performance to see if it was worth reusing the figure within a batch, and this little sample program slowed from 41s to 49s (20% slower) when I just called close() after every plot.

To add to the alternatives, using @akrun's sample data, I would do the following:

d1[] <- lapply(d1, function(x) { 
  x[is.na(x)] <- mean(x, na.rm = TRUE)
  x
})
d1

Checkout CefSharp .Net bindings, a project I started a while back that thankfully got picked up by the community and turned into something wonderful.

The project wraps the Chromium Embedded Framework and has been used in a number of major projects including Rdio's Windows client, Facebook Messenger for Windows and Github for Windows.

It features browser controls for WPF and Winforms and has tons of features and extension points. Being based on Chromium it's blisteringly fast too.

Grab it from NuGet: Install-Package CefSharp.Wpf or Install-Package CefSharp.WinForms

For Swift 3, you will mostly be converting from String to Data.

let myString = "test"
let myData = myString.data(using: .utf8)
print(myData) // Optional(Data)

If you debug your code using developer tools, you will notice that this refers to the window object and not the input control. Consider using the passed in id to retrieve the input and check for checked value.

function doalert(id){
  if(document.getElementById(id).checked) {
    alert('checked');
  }else{
    alert('unchecked');
  }
}

No you cannot force a file that is already committed in the repo to be removed just because it is added to the .gitignore

You have to git rm --cached to remove the files that you don't want in the repo. ( --cached since you probably want to keep the local copy but remove from the repo. ) So if you want to remove all the exe's from your repo do

git rm --cached /\*.exe

(Note that the asterisk * is quoted from the shell - this lets git, and not the shell, expand the pathnames of files and subdirectories)

There are three things to consider here:

1. Don't assume that the sd card is mounted at /sdcard (May be true in the default case, but better not to hard code.). You can get the location of sdcard by querying the system:

   Environment.getExternalStorageDirectory();
   

2. You have to inform Android that your application needs to write to external storage by adding a uses-permission entry in the AndroidManifest.xml file:

   <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
   

3. If this directory already exists, then mkdir is going to return false. So check for the existence of the directory, and then try creating it if it does not exist. In your component, use something like:

   File folder = new File(Environment.getExternalStorageDirectory() + "/map");
   boolean success = true;
   if (!folder.exists()) {
       success = folder.mkdir();
   }
   if (success) {
       // Do something on success
   } else {
       // Do something else on failure 
   }
   

This is cleaner and will put in a csv.

In cmd when you use > or >> the output will be only written on the file. Is it possible to see the output in the cmd windows and also save it in a file. Something similar if you use teraterm, when you can start saving all the log in a file meanwhile you use the console and view it (only for ssh, telnet and serial).

Problem seems to be associated with the SET statement. I think the expression can't be more than 4,000 bytes in size. There is no need to make any changes to any settings if all you are trying to do is to assign a dynamically generated statement that is more than 4,000 characters. What you need to do is to split your assignment. If your statement is 6,000 characters long, find a logical break point and then concatenate second half to the same variable. For example:

SET @Query = 'SELECT ....' [Up To 4,000 characters, then rest of statement as below]

SET @Query = @Query + [rest of statement]

Now run your query as normal i.e. EXEC ( @Query )

However, if you do end up using rm instead of git rm. You can skip the git add and directly commit the changes using:

git commit -a

Kotlin supports type aliases https://kotlinlang.org/docs/reference/type-aliases.html. You can rename types and function types.

To convert Blob to String in Java:

byte[] bytes = baos.toByteArray();//Convert into Byte array
String blobString = new String(bytes);//Convert Byte Array into String

One of the first things you need to learn about SQL (and relational databases) is that you shouldn't store multiple values in a single field.

You should create another table and store one value per row.

This will make your querying easier, and your database structure better.

select 
    case when exists (select countryname from itemcountries where yourtable.id=itemcountries.id and countryname = @country) then 'national' else 'regional' end
from yourtable

Couldn't find any official documentation (no surprise there) but according to this interesting article, those elements are injected in order to enable Word to convert the HTML back to fully compatible Word document, with everything preserved.

The relevant paragraph:

Microsoft added the special tags to Word's HTML with an eye toward backward compatibility. Microsoft wanted you to be able to save files in HTML complete with all of the tracking, comments, formatting, and other special Word features found in traditional DOC files. If you save a file in HTML and then reload it in Word, theoretically you don't loose anything at all.

This makes lots of sense.

For your specific question.. the o in the <o:p> means "Office namespace" so anything following the o: in a tag means "I'm part of Office namespace" - in case of <o:p> it just means paragraph, the equivalent of the ordinary <p> tag.

I assume that every HTML tag has its Office "equivalent" and they have more.

Quick and dirty:

#!/usr/bin/perl -w

use strict;

open(FILE, "</tmp/yourfile.txt") || die "File not found";
my @lines = <FILE>;
close(FILE);

foreach(@lines) {
   $_ =~ s/<PREF>/ABCD/g;
}

open(FILE, ">/tmp/yourfile.txt") || die "File not found";
print FILE @lines;
close(FILE);

Perhaps it i a good idea not to write the result back to your original file; instead write it to a copy and check the result first.

This simplest safe & general solution is probably:

find -mindepth 1 -maxdepth 1 -print0 | xargs -0 rm -rf

If u need to connect your application to a server you can do it through PHP/MySQL and JSON http://www.androidhive.info/2012/05/how-to-connect-android-with-php-mysql/ .Mysql Connection code should be in AsynTask class. Dont run it in Main Thread.

I found this solution.I download JDK 8.Then I add downloading jdk file path name of JAVA_HOME into user variables in environment variable.

VB Code:

Dim ListItem1 As New ListItem()
ListItem1.Text = "put anything here"
ListItem1.Value = "0"
drpTag.DataBind()
drpTag.Items.Insert(0, ListItem1)

View:

<asp:CompareValidator ID="CompareValidator1" runat="server" ErrorMessage="CompareValidator" ControlToValidate="drpTag" 
  ValueToCompare="0">
</asp:CompareValidator>

set ORACLE_SID=<YOUR_SID>
sqlplus "/as sysdba"
alter system disable restricted session;

or maybe

shutdown abort;

or maybe

Personally I would just use Powermock along with Mockito or Easymock to mock the static SecurityContextHolder.getSecurityContext() in your unit/integration test e.g.

@RunWith(PowerMockRunner.class)
@PrepareForTest(SecurityContextHolder.class)
public class YourTestCase {

    @Mock SecurityContext mockSecurityContext;

    @Test
    public void testMethodThatCallsStaticMethod() {
        // Set mock behaviour/expectations on the mockSecurityContext
        when(mockSecurityContext.getAuthentication()).thenReturn(...)
        ...
        // Tell mockito to use Powermock to mock the SecurityContextHolder
        PowerMockito.mockStatic(SecurityContextHolder.class);

        // use Mockito to set up your expectation on SecurityContextHolder.getSecurityContext()
        Mockito.when(SecurityContextHolder.getSecurityContext()).thenReturn(mockSecurityContext);
        ...
    }
}

Admittedly there is quite a bit of boiler plate code here i.e. mock an Authentication object, mock a SecurityContext to return the Authentication and finally mock the SecurityContextHolder to get the SecurityContext, however its very flexible and allows you to unit test for scenarios like null Authentication objects etc. without having to change your (non test) code

Open res -> values -> styles.xml and to your <style> add this line replacing with your image path <item name="android:windowBackground">@drawable/background</item>. Example:

<resources>

    <!-- Base application theme. -->
    <style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
        <!-- Customize your theme here. -->
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
        <item name="android:windowBackground">@drawable/background</item>
    </style>

</resources>

There is a <item name ="android:colorBackground">@color/black</item> also, that will affect not only your main window background but all the component in your app. Read about customize theme here.

If you want version specific styles:

If a new version of Android adds theme attributes that you want to use, you can add them to your theme while still being compatible with old versions. All you need is another styles.xml file saved in a values directory that includes the resource version qualifier. For example:

res/values/styles.xml        # themes for all versions
res/values-v21/styles.xml    # themes for API level 21+ only

Because the styles in the values/styles.xml file are available for all versions, your themes in values-v21/styles.xml can inherit them. As such, you can avoid duplicating styles by beginning with a "base" theme and then extending it in your version-specific styles.

Read more here(doc in theme).

You probably need to do a git stash before you git pull, this is because it is reading your old config file. So do:

git stash
git pull
git commit -am <"say first commit">
git push

Also see git-stash(1) Manual Page.

My solution:

def seq(start, stop, step=1, digit=0):
    x = float(start)
    v = []
    while x <= stop:
        v.append(round(x,digit))
        x += step
    return v

For IE > 9 you can use the following solution:

@font-face {
    font-family: OpenSansRegular;
    src: url('OpenSansRegular.ttf'), url('OpenSansRegular.eot');
}

You'll need to cast it:

export type Fruit = "Orange" | "Apple" | "Banana";
let myString: string = "Banana";

let myFruit: Fruit = myString as Fruit;

Also notice that when using string literals you need to use only one |

Edit

As mentioned in the other answer by @Simon_Weaver, it's now possible to assert it to const:

let fruit = "Banana" as const;

Solution without hardcoding origin in config

Use the following in your global gitconfig

[remote]
    push = +refs/heads/*
    push = +refs/tags/*

This pushes all branches and all tags

Why should you NOT hardcode origin in config?

If you hardcode:

1. You'll end up with origin as a remote in all repos. So you'll not be able to add origin, but you need to use set-url.
2. If a tool creates a remote with a different name push all config will not apply. Then you'll have to rename the remote, but rename will not work because origin already exists (from point 1) remember :)

Fetching is taken care of already by modern git

As per Jakub Narebski's answer:

With modern git you always fetch all branches (as remote-tracking branches into refs/remotes/origin/* namespace

Zapping - you can use this javascript lib; DefiantJS. There is no need to restructure JSON data into objects to ease searching. Instead, you can search the JSON structure with an XPath expression like this:

    var data = [
   {
      "id": "one",
      "pId": "foo1",
      "cId": "bar1"
   },
   {
      "id": "two",
      "pId": "foo2",
      "cId": "bar2"
   },
   {
      "id": "three",
      "pId": "foo3",
      "cId": "bar3"
   }
],
res = JSON.search( data, '//*[id="one"]' );

console.log( res[0].cId );
// 'bar1'

DefiantJS extends the global object JSON with a new method; "search" which returns array with the matches (empty array if none were found). You can try it out yourself by pasting your JSON data and testing different XPath queries here:

http://www.defiantjs.com/#xpath_evaluator

XPath is, as you know, a standardised query language.

Beginning PowerShell 5.0 New-Item, Remove-Item, and Get-ChildItem have been enhanced to support creating and managing symbolic links. The ItemType parameter for New-Item accepts a new value, SymbolicLink. Now you can create symbolic links in a single line by running the New-Item cmdlet.

New-Item -ItemType SymbolicLink -Path "C:\temp" -Name "calc.lnk" -Value "c:\windows\system32\calc.exe"

Be Carefull a SymbolicLink is different from a Shortcut, shortcuts are just a file. They have a size (A small one, that just references where they point) and they require an application to support that filetype in order to be used. A symbolic link is filesystem level, and everything sees it as the original file. An application needs no special support to use a symbolic link.

Anyway if you want to create a Run As Administrator shortcut using Powershell you can use

$file="c:\temp\calc.lnk"
$bytes = [System.IO.File]::ReadAllBytes($file)
$bytes[0x15] = $bytes[0x15] -bor 0x20 #set byte 21 (0x15) bit 6 (0x20) ON (Use –bor to set RunAsAdministrator option and –bxor to unset)
[System.IO.File]::WriteAllBytes($file, $bytes)

If anybody want to change something else in a .LNK file you can refer to official Microsoft documentation.

What you need, according to your comments, is a 'BLOB' (Binary Large OBject) for both image and resume.

ugh, just to iterate over my own case, which gave out approximately the same error - in the Resource declaration (server.xml) make sure to NOT omit driverClassName, and that e.g. for Oracle it is "oracle.jdbc.OracleDriver", and that the right JAR file (e.g. ojdbc14.jar) exists in %CATALINA_HOME%/lib

I suggest you use Promise

myApp.service('dataService', function($http,$q) {

  delete $http.defaults.headers.common['X-Requested-With'];
  this.getData = function() {
     deferred = $q.defer();
     $http({
         method: 'GET',
         url: 'https://www.example.com/api/v1/page',
         params: 'limit=10, sort_by=created:desc',
         headers: {'Authorization': 'Token token=xxxxYYYYZzzz'}
     }).success(function(data){
         // With the data succesfully returned, we can resolve promise and we can access it in controller
         deferred.resolve();
     }).error(function(){
          alert("error");
          //let the function caller know the error
          deferred.reject(error);
     });
     return deferred.promise;
  }
});

so In your controller you can use the method

myApp.controller('AngularJSCtrl', function($scope, dataService) {
    $scope.data = null;
    dataService.getData().then(function(response) {
        $scope.data = response;
    });
});

promises are powerful feature of angularjs and it is convenient special if you want to avoid nesting callbacks.

Calling preventDefault on touchmove while you're actively scrolling is not working in Chrome. To prevent performance issues, you cannot interrupt a scroll.

Try to call preventDefault() from touchstart and everything should be ok.

F5 and the refresh button will look at your browser cache before asking the server for content.

Ctrl + F5 forces a load from the server.

You can set content expiration headers and/or meta tags to ensure the browser doesn't cache anything (perhaps something you can do only for the development environment).

Also, if you have a variable,

CabRes::where('m_Id', 46)
      ->where('t_Id', 2)
      ->where(function($q) use ($variable){
          $q->where('Cab', 2)
            ->orWhere('Cab', $variable);
      })
      ->get();

$ne

selects the documents where the value of the field is not equal to the specified value. This includes documents that do not contain the field.

User.find({ "username": { "$ne": 'admin' } })

$nin

$nin selects the documents where: the field value is not in the specified array or the field does not exist.

User.find({ "groups": { "$nin": ['admin', 'user'] } })

for eg. you may take

driver.get('https://www.naukri.com/')

since, it is a current window ,we can name it

main_page = driver.current_window_handle

if there are atleast 1 window popup except the current window,you may try this method and put if condition in break statement by hit n trial for the index

for handle in driver.window_handles:
    if handle != main_page:
        print(handle)
        login_page = handle
        break

driver.switch_to.window(login_page)

Now ,whatever the credentials you have to apply,provide after it is loggen in. Window will disappear, but you have to come to main page window and you are done

driver.switch_to.window(main_page)
sleep(10)

Here's another way to process command line args, using R CMD BATCH. My approach, which builds on an earlier answer here, lets you specify arguments at the command line and, in your R script, give some or all of them default values.

Here's an R file, which I name test.R:

defaults <- list(a=1, b=c(1,1,1)) ## default values of any arguments we might pass

## parse each command arg, loading it into global environment
for (arg in commandArgs(TRUE))
  eval(parse(text=arg))

## if any variable named in defaults doesn't exist, then create it
## with value from defaults
for (nm in names(defaults))
  assign(nm, mget(nm, ifnotfound=list(defaults[[nm]]))[[1]])

print(a)
print(b)

At the command line, if I type

R CMD BATCH --no-save --no-restore '--args a=2 b=c(2,5,6)' test.R

then within R we'll have a = 2 and b = c(2,5,6). But I could, say, omit b, and add in another argument c:

R CMD BATCH --no-save --no-restore '--args a=2 c="hello"' test.R

Then in R we'll have a = 2, b = c(1,1,1) (the default), and c = "hello".

Finally, for convenience we can wrap the R code in a function, as long as we're careful about the environment:

## defaults should be either NULL or a named list
parseCommandArgs <- function(defaults=NULL, envir=globalenv()) {
  for (arg in commandArgs(TRUE))
    eval(parse(text=arg), envir=envir)

  for (nm in names(defaults))
    assign(nm, mget(nm, ifnotfound=list(defaults[[nm]]), envir=envir)[[1]], pos=envir)
}

## example usage:
parseCommandArgs(list(a=1, b=c(1,1,1)))

If you don't have specific needs you can just do this:

if ($(window).width() < 768) {
    // do something for small screens
}
else if ($(window).width() >= 768 &&  $(window).width() <= 992) {
    // do something for medium screens
}
else if ($(window).width() > 992 &&  $(window).width() <= 1200) {
    // do something for big screens
}
else  {
    // do something for huge screens
}

Edit: I don't see why you should use another js library when you can do this just with jQuery already included in your Bootstrap project.

TLDR

~ is what you want most of the time, it references past commits to the current branch

^ references parents (git-merge creates a 2nd parent or more)

A~ is always the same as A^
A~~ is always the same as A^^, and so on
A~2 is not the same as A^2 however,
because ~2 is shorthand for ~~
while ^2 is not shorthand for anything, it means the 2nd parent

This declaration:

char s[] = "hello";

Creates one object - a char array of size 6, called s, initialised with the values 'h', 'e', 'l', 'l', 'o', '\0'. Where this array is allocated in memory, and how long it lives for, depends on where the declaration appears. If the declaration is within a function, it will live until the end of the block that it is declared in, and almost certainly be allocated on the stack; if it's outside a function, it will probably be stored within an "initialised data segment" that is loaded from the executable file into writeable memory when the program is run.

On the other hand, this declaration:

char *s ="hello";

Creates two objects:

• a read-only array of 6 chars containing the values 'h', 'e', 'l', 'l', 'o', '\0', which has no name and has static storage duration (meaning that it lives for the entire life of the program); and
• a variable of type pointer-to-char, called s, which is initialised with the location of the first character in that unnamed, read-only array.

The unnamed read-only array is typically located in the "text" segment of the program, which means it is loaded from disk into read-only memory, along with the code itself. The location of the s pointer variable in memory depends on where the declaration appears (just like in the first example).

That depends on what the target server accepts. There is no definitive standard for this. See also a.o. Wikipedia: Query string:

While there is no definitive standard, most web frameworks allow multiple values to be associated with a single field (e.g. field1=value1&field1=value2&field2=value3).^[4][5]

Generally, when the target server uses a strong typed programming language like Java (Servlet), then you can just send them as multiple parameters with the same name. The API usually offers a dedicated method to obtain multiple parameter values as an array.

foo=value1&foo=value2&foo=value3

String[] foo = request.getParameterValues("foo"); // [value1, value2, value3]

The request.getParameter("foo") will also work on it, but it'll return only the first value.

String foo = request.getParameter("foo"); // value1

And, when the target server uses a weak typed language like PHP or RoR, then you need to suffix the parameter name with braces [] in order to trigger the language to return an array of values instead of a single value.

foo[]=value1&foo[]=value2&foo[]=value3

$foo = $_GET["foo"]; // [value1, value2, value3]
echo is_array($foo); // true

In case you still use foo=value1&foo=value2&foo=value3, then it'll return only the first value.

$foo = $_GET["foo"]; // value1
echo is_array($foo); // false

Do note that when you send foo[]=value1&foo[]=value2&foo[]=value3 to a Java Servlet, then you can still obtain them, but you'd need to use the exact parameter name including the braces.

String[] foo = request.getParameterValues("foo[]"); // [value1, value2, value3]

The pythonic way.

print "".join([ c if c.isalnum() else "*" for c in s ])

This doesn't deal with grouping multiple consecutive non-matching characters though, i.e.

"h^&i => "h**i not "h*i" as in the regex solutions.

Another way is using a ResourceBundle. Basically you get the bundle using its name without the '.properties'

private static final ResourceBundle resource = ResourceBundle.getBundle("config");

And you recover any value using this:

private final String prop = resource.getString("propName");

I have a child aspx form that does an address lookup server side. The values from the child aspx page are then passed back to the parent textboxes via javascript client side.

Although you can see the textboxes have been changed neither ReadOnly or Enabled would allow the values to be posted back in the parent form.

df2 <- data.frame(apply(df1, 2, function(x) as.numeric(as.character(x))))

Its possible you don't need to know depending on what you are doing with it.

String myString = object.toString();

or if object can be null

String myString = String.valueOf(object);

awk only

awk 'BEGIN{FS=""}{for(i=1;i<=NF;i++)c++}END{print "total chars:"c}' file

shell only

var=$(<file)
echo ${#var}

This was on Ubuntu 14.04 after install qt5-qmake. qmake was a symlink to qtchooser which takes the -qt argument.

            && c.CompanyId == companyId

                 c => c.Id,
                 (s, c) => new { s, c })
           .Where(sc => sc.c.Id == userId && sc.c.CompanyId == companId)
           .Select(sc => sc.s);

Basically I solved it by NOT-ing the isReplyFormOpen value whenever it is clicked:

<a ng-click="isReplyFormOpen = !isReplyFormOpen">Reply</a>

<div ng-init="isReplyFormOpen = false" ng-show="isReplyFormOpen" id="replyForm">
    <!-- Form -->
</div>

The problem with the answer with the most votes is it doesn't explain the reasoning for the solution.

For the lines Require ip 127.0.0.1, you should instead add the ip address of the host that plans to access phpMyAdmin from a browser. For example Require ip 192.168.0.100. The Require ip 127.0.0.1 allows localhost access to phpMyAdmin.

Restart apache (httpd) after making changes. I would suggest testing on localhost, or using command line tools like curl to very a http GET works, and there is no other configuration issue.

Ian put this in the comment, but I think it's a good answer:

if (exists("aVariable"))
{
  do whatever
}

note that the variable name is quoted.

I realize this is an old question and has been answered but this could help someone. In your activity

private ScheduledExecutorService scheduleTaskExecutor;

In onCreate

  scheduleTaskExecutor = Executors.newScheduledThreadPool(5);

    //Schedule a task to run every 5 seconds (or however long you want)
    scheduleTaskExecutor.scheduleAtFixedRate(new Runnable() {
        @Override
        public void run() {
            // Do stuff here!

            runOnUiThread(new Runnable() {
                @Override
                public void run() {
                    // Do stuff to update UI here!
                    Toast.makeText(MainActivity.this, "Its been 5 seconds", Toast.LENGTH_SHORT).show();
                }
            });

        }
    }, 0, 5, TimeUnit.SECONDS); // or .MINUTES, .HOURS etc.

I finally found the solution.

1. Remove webpack by using following command.

npm remove webpack

2. Install cli by using following command.

npm install --save-dev @angular/cli@latest

after successfully test app, it will work :)

If not then follow below steps:

1. Delete node_module folder.
2. Clear cache by using following command.

npm cache clean --force

3. Install node packages by using following command.

npm install

4. Install angular@cli by using following command.

npm install --save-dev @angular/cli@latest

Note: If failed, try step 4 again. It will work.

To check if variable is null or empty use this:

IF LEN(ISNULL(@var, '')) = 0
    -- Is empty or NULL
ELSE
    -- Is not empty and is not NULL

Use

var rootObject =  JsonConvert.DeserializeObject<RootObject>(string json);

Create your classes on JSON 2 C#

Json.NET documentation: Serializing and Deserializing JSON with Json.NET

This might help: https://stackoverflow.com/a/4196465/683114

if (navigator.userAgent.toLowerCase().indexOf("chrome") >= 0) {
    $(window).load(function(){
        $('input:-webkit-autofill').each(function(){
            var text = $(this).val();
            var name = $(this).attr('name');
            $(this).after(this.outerHTML).remove();
            $('input[name=' + name + ']').val(text);
        });
    });
}

It looks like on load, it finds all inputs with autofill, adds their outerHTML and removes the original, while preserving value and name (easily changed to preserve ID etc)

If this preserves the autofill text, you could just set

var text = "";   /* $(this).val(); */

From the original form where this was posted, it claims to preserve autocomplete. :)

Good luck!

Specifying a non-static position, e.g., position: absolute/relative on a node means that it will be used as the reference for absolutely positioned elements within it http://jsfiddle.net/E5eEk/1/

See https://developer.mozilla.org/en-US/docs/Learn/CSS/CSS_layout/Positioning#Positioning_contexts

We can change the positioning context — which element the absolutely positioned element is positioned relative to. This is done by setting positioning on one of the element's ancestors.

  min-width: 2000px; _x000D_
  min-height: 1000px; _x000D_

The C++-canonical way: Don't check for errors...use the C++ bindings which throw exceptions.

I used to be irked by this problem; and I used to have a macro-cum-wrapper-function solution just like in Talonmies and Jared's answers, but, honestly? It makes using the CUDA Runtime API even more ugly and C-like.

So I've approached this in a different and more fundamental way. For a sample of the result, here's part of the CUDA vectorAdd sample - with complete error checking of every runtime API call:

// (... prepare host-side buffers here ...)

auto current_device = cuda::device::current::get();
auto d_A = cuda::memory::device::make_unique<float[]>(current_device, numElements);
auto d_B = cuda::memory::device::make_unique<float[]>(current_device, numElements);
auto d_C = cuda::memory::device::make_unique<float[]>(current_device, numElements);

cuda::memory::copy(d_A.get(), h_A.get(), size);
cuda::memory::copy(d_B.get(), h_B.get(), size);

// (... prepare a launch configuration here... )

cuda::launch(vectorAdd, launch_config,
    d_A.get(), d_B.get(), d_C.get(), numElements
);    
cuda::memory::copy(h_C.get(), d_C.get(), size);

// (... verify results here...)

Again - all potential errors are checked , and an exception if an error occurred (caveat: If the kernel caused some error after launch, it will be caught after the attempt to copy the result, not before; to ensure the kernel was successful you would need to check for error between the launch and the copy with a cuda::outstanding_error::ensure_none() command).

The code above uses my

Thin Modern-C++ wrappers for the CUDA Runtime API library (Github)

Note that the exceptions carry both a string explanation and the CUDA runtime API status code after the failing call.

A few links to how CUDA errors are automagically checked with these wrappers:

• A test program throwing and catching a bunch of exceptions
• Documentation for the error-related functionality

You can do in this way:

int[] numbers= {1,3,4,9,2};     
List<int> lst_numbers = new List<int>(numbers);
int required_number = 4;
int i = 0;
foreach (int number in lst_numbers)
{              
    if(number == required_number)
    {
        break;
    }
    i++;
}
lst_numbers.RemoveAt(i);
numbers = lst_numbers.ToArray();        

Look at a JUnit report. JUnit is already organized by package. Each package has (or can have) TestSuite classes, each of which in turn run multiple TestCases. Each TestCase can have multiple test methods of the form public void test*(), each of which will actually become an instance of the TestCase class to which they belong. Each test method (TestCase instance) has a name and a pass/fail criteria.

What my management requires is the concept of individual TestStep items, each of which reports their own pass/fail criteria. Failure of any test step must not prevent the execution of subsequent test steps.

In the past, test developers in my position organized TestCase classes into packages that correspond to the part(s) of the product under test, created a TestCase class for each test, and made each test method a separate "step" in the test, complete with its own pass/fail criteria in the JUnit output. Each TestCase is a standalone "test", but the individual methods, or test "steps" within the TestCase, must occur in a specific order.

The TestCase methods were the steps of the TestCase, and test designers got a separate pass/fail criterion per test step. Now the test steps are jumbled, and the tests (of course) fail.

For example:

Class testStateChanges extends TestCase

public void testCreateObjectPlacesTheObjectInStateA()
public void testTransitionToStateBAndValidateStateB()
public void testTransitionToStateCAndValidateStateC()
public void testTryToDeleteObjectinStateCAndValidateObjectStillExists()
public void testTransitionToStateAAndValidateStateA()
public void testDeleteObjectInStateAAndObjectDoesNotExist()
public void cleanupIfAnythingWentWrong()

Each test method asserts and reports its own separate pass/fail criteria. Collapsing this into "one big test method" for the sake of ordering loses the pass/fail criteria granularity of each "step" in the JUnit summary report. ...and that upsets my managers. They are currently demanding another alternative.

Can anyone explain how a JUnit with scrambled test method ordering would support separate pass/fail criteria of each sequential test step, as exemplified above and required by my management?

Regardless of the documentation, I see this as a serious regression in the JUnit framework that is making life difficult for lots of test developers.

That name looks derived from an object URL GUID. Do the following to get the object URL that the name was derived from.

var URL = self.URL || self.webkitURL || self;
var object_url = URL.createObjectURL(blob);
URL.revokeObjectURL(object_url);

object_url will be formatted as blob:{origin}{GUID} in Google Chrome and moz-filedata:{GUID} in Firefox. An origin is the protocol+host+non-standard port for the protocol. For example, blob:http://stackoverflow.com/e7bc644d-d174-4d5e-b85d-beeb89c17743 or blob:http://[::1]:123/15111656-e46c-411d-a697-a09d23ec9a99. You probably want to extract the GUID and strip any dashes.

You can use the below code to submit the form using JavaScript:

document.getElementById('FormID').submit();

I was creating a form in which the user enters an email address used by another macro to email a specific cell group to the address entered. I patched together this simple code from several sites and my limited knowledge of VBA. This simply watches for one cell (In my case K22) to be updated and then kills any hyperlink in that cell.

Private Sub Worksheet_Change(ByVal Target As Range)
    Dim KeyCells As Range

    ' The variable KeyCells contains the cells that will
    ' cause an alert when they are changed.
    Set KeyCells = Range("K22")

    If Not Application.Intersect(KeyCells, Range(Target.Address)) _
           Is Nothing Then

        Range("K22").Select
        Selection.Hyperlinks.Delete

    End If 
End Sub

Yes, you can put arrays in sessions, example:

$_SESSION['name_here'] = $your_array;

Now you can use the $_SESSION['name_here'] on any page you want but make sure that you put the session_start() line before using any session functions, so you code should look something like this:

 session_start();
 $_SESSION['name_here'] = $your_array;

Possible Example:

 session_start();
 $_SESSION['name_here'] = $_POST;

Now you can get field values on any page like this:

 echo $_SESSION['name_here']['field_name'];

As for the second part of your question, the session variables remain there unless you assign different array data:

 $_SESSION['name_here'] = $your_array;

Session life time is set into php.ini file.

The most likely reason for the error is that the certificate authority that issued your SSL certificate is trusted on your desktop, but not on your mobile.

If you purchased the certificate from a common certification authority, it shouldn't be an issue - but if it is a less common one it is possible that your phone doesn't have it. You may need to accept it as a trusted publisher (although this is not ideal if you are pushing the site to the public as they won't be willing to do this.)

You might find looking at a list of Trusted CAs for Android helps to see if yours is there or not.

Built off the above but with dynamic creation and a vector image, not drawing.

function svgztruck() {
    tok = "{d path value}"
    return tok;
}

function buildsvg( eid ) {
    console.log("building");
    var zvg = "svg" + eid;
    var vvg = eval( zvg );
    var raw = vvg();

    var svg = document.getElementById( eid );
    svg.setAttributeNS(null,"d", raw );
    svg.setAttributeNS(null,"fill","green");
    svg.setAttributeNS(null,"onlick", eid + ".style.fill=#FF0000");
    return;
}

You could call with:

<img src="" onerror="buildscript">

Now you can add colors by sub element and manipulate all elements of the dom directly. It is important to implement your viewbox and height width first on the svg html, not done in the example above.

There is no need to make your code 10 pages when it could be one... but who am I to argue. Better use PHP while your at it.

The inner element that svg builds on is a simple <svg lamencoding id=parenteid><path id=eid><svg> with nothing else.

Postgres hasn't implemented an equivalent to INSERT OR REPLACE. From the ON CONFLICT docs (emphasis mine):

It can be either DO NOTHING, or a DO UPDATE clause specifying the exact details of the UPDATE action to be performed in case of a conflict.

Though it doesn't give you shorthand for replacement, ON CONFLICT DO UPDATE applies more generally, since it lets you set new values based on preexisting data. For example:

INSERT INTO users (id, level)
VALUES (1, 0)
ON CONFLICT (id) DO UPDATE
SET level = users.level + 1;

I solved the problem by applying box-sizing:border-box; to the table cells themselves, besides doing the same with the input and the wrapper.

bool isFirst = compareString.Contains(firstString);
bool isSecond = compareString.Contains(secondString );

Another way to make column aligned is as follows:

using namespace std;

cout.width(20); cout << left << "Artist";
cout.width(20); cout << left << "Title";
cout.width(10); cout << left << "Price";
...
cout.width(20); cout << left << artist;
cout.width(20); cout << left << title;
cout.width(10); cout << left << price;

We should estimate maximum length of values for each column. In this case, values of "Artist" column should not exceed 20 characters and so on.

If you don't want to remove duplicates, then try this

Use LINQ:

var arr1 = new[] { 1, 2, 3, 4, 5 };
var arr2 = new[] { 6, 7, 8, 9, 0 };
var arr = arr1.Concat(arr2).ToArray();

You can also try doing this using one of many third party tools that are available for this.

Queries are great for simple searches but if you need to do more manipulation with data, search for references and such this is where you can do a much better job with these.

Also, these come in very handy when some objects are encrypted and you need to search for

I’m using ApexSQL Search which is free but there are also many more (also free) on the market such as Red Gate or SSMS Tool Pack.

The onMessageReceived method is fired only when app is in foreground or the notification payload only contains the data type.

From the Firebase docs

For downstream messaging, FCM provides two types of payload: notification and data.

For notification type, FCM automatically displays the message to end-user devices on behalf of the client app. Notifications have a predefined set of user-visible keys.
For data type, client app is responsible for processing data messages. Data messages have only custom key-value pairs.

Use notifications when you want FCM to handle displaying a notification on your client app's behalf. Use data messages when you want your app to handle the display or process the messages on your Android client app, or if you want to send messages to iOS devices when there is a direct FCM connection.

Further down the docs

App behaviour when receiving messages that include both notification and data payloads depends on whether the app is in the background or the foreground—essentially, whether or not it is active at the time of receipt.
When in the background, apps receive the notification payload in the notification tray, and only handle the data payload when the user taps on the notification.
When in the foreground, your app receives a message object with both payloads available.

If you are using the firebase console to send notifications, the payload will always contain the notification type. You have to use the Firebase API to send the notification with only the data type in the notification payload. That way your app is always notified when a new notification is received and the app can handle the notification payload.

If you want to play notification sound when app is in background using the conventional method, you need to add the sound parameter to the notification payload.

You can specify maven source/target version by adding these properties to your pom.xml file

<properties>
    <maven.compiler.source>1.6</maven.compiler.source>
    <maven.compiler.target>1.6</maven.compiler.target>
</properties>

Or use group_by & summarise_at from the dplyr package:

library(dplyr)

d %>%
  group_by(Name) %>%
  summarise_at(vars(-Month), funs(mean(., na.rm=TRUE)))

# A tibble: 3 x 3
  Name  Rate1 Rate2
  <fct> <dbl> <dbl>
1 Aira   16.3  47.0
2 Ben    31.3  50.3
3 Cat    44.7  54.0

See ?summarise_at for the many ways to specify the variables to act on. Here, vars(-Month) says all variables except Month.

This solution is extracted directly from tiddlywiki's (tiddlywiki.com) github repository. I have used tiddlywiki in almost all browsers and it works like a charm:

    link.setAttribute("target","_blank");
    if(Blob !== undefined) {
        var blob = new Blob([text], {type: "text/plain"});
        link.setAttribute("href", URL.createObjectURL(blob));
    } else {
        link.setAttribute("href","data:text/plain," + encodeURIComponent(text));
    }
    link.setAttribute("download",filename);
    document.body.appendChild(link);
    link.click();
    document.body.removeChild(link);
}

Normally there's no need for that. First of all

echo $CLASSPATH

If there's something in there, you probably want to check Applications -> Utilites -> Java.

getDay() returns the day of the week. To get the date, use date.getDate(). getMonth() retrieves the month, but month is zero based, so using getMonth()+1 should give you the right month. Time value seems to be ok here, albeit the hour is 23 here (GMT+1). If you want universal values, add UTC to the methods (e.g. date.getUTCFullYear(), date.getUTCHours())

var timestamp = 1301090400,
date = new Date(timestamp * 1000),
datevalues = [
   date.getFullYear(),
   date.getMonth()+1,
   date.getDate(),
   date.getHours(),
   date.getMinutes(),
   date.getSeconds(),
];
alert(datevalues); //=> [2011, 3, 25, 23, 0, 0]

Follow the steps:-

1. 1] sqlite3 name 2] .mode csv tablename 3] .import Filename.csv tablename

you can use

reader.GetInt32(3);

to read an 32 bit int from the data reader.

If you know the type of your data I think its better to read using the Get* methods which are strongly typed rather than just reading an object and casting.

Have you considered using

reader.GetInt32(reader.GetOrdinal(columnName)) 

rather than accessing by position. This makes your code less brittle and will not break if you change the query to add new columns before the existing ones. If you are going to do this in a loop, cache the ordinal first.

Memcached is a newer API, it also provides memcached as a session provider which could be great if you have a farm of server.

After the version is still really low 0.2 but I have used both and I didn't encounter major problem, so I would go to memcached since it's new.

IMHO you could just send the JSON encoded (ie. encodeURIComponent) in the URL, this way you do not violate the HTTP specs and get your JSON to the server.

I had similar problem with my "Xiaomi Redmi Note 4" and tried almost 10 solutions I found over internet, but none of them helped my case. I've posted this answer to help someones like myself.

Installing "Intel USB Driver for Android Devices" totally solved my problem. It's described completely here.

This works from Java 5 to 7:

public int getTheNumber(Integer... factors) {
    ArrayList<Integer> f = new ArrayList<Integer>(Arrays.asList(factors));
    Collections.sort(f);
    return f.get(0)*f.get(f.size()-1);
}

In Java 4 there is no vararg... :-)

To increase the phpMyAdmin Session Timeout, open config.inc.php in the root phpMyAdmin directory and add this setting (anywhere).

$cfg['LoginCookieValidity'] = <your_new_timeout>;

Where <your_new_timeout> is some number larger than 1800.

Note:

Always keep on mind that a short cookie lifetime is all well and good for the development server. So do not do this on your production server.

// The below C++ function checks for a palindrome and 
// returns true if it is a palindrome and returns false otherwise

bool checkPalindrome ( string s )
{
    // This calculates the length of the string

    int n = s.length();

    // the for loop iterates until the first half of the string
    // and checks first element with the last element,
    // second element with second last element and so on.
    // if those two characters are not same, hence we return false because
    // this string is not a palindrome 

    for ( int i = 0; i <= n/2; i++ ) 
    {
        if ( s[i] != s[n-1-i] )
            return false;
    }
    
    // if the above for loop executes completely , 
    // this implies that the string is palindrome, 
    // hence we return true and exit

    return true;
}

For resolving a single parameter (I guess what's most commonly needed), this is the simplest I found:

For sentOs, it's works for me At first stop service by sudo service jenkins stop

Than remove by sudo yum remove jenkins

I believe that variable names aren't stored in pyc/pyd/pyo files, so you can not retrieve the exact code lines if you don't have source files.

While @tymeJV gave a correct answer, the way to do this to be inline with angular would be:

ng-click="hidePrefs()"

and then in your controller:

$scope.hidePrefs = function() {  
  $scope.prefs = false;
}

Solved with the following example:

public void CheckConsoleOutput()
{
    Console.WriteLine("Hello, World!");
    Trace.WriteLine("Trace Trace the World");
    Debug.WriteLine("Debug Debug World");
    Assert.IsTrue(true);
}

After running this test, under 'Test Passed', there is the option to view the output, which will bring up the output window.

I found the answer I was looking for. The thing to use here is the construct of

\left \middle \right

For example, in this case, two possible solutions are:

$\left( {\frac{a_1}{a_2}} \middle/ {\frac{b_1}{b_2}} \right) $

Or, in case the brackets are not necessary:

$\left. {\frac{a_1}{a_2}} \middle/ {\frac{b_1}{b_2}} \right. $

For those like me who struggled to get @Sunny Shah accepted answer to work on iPads. You need to set the "Requires full screen" checkbox on in the project settings. Note that this will prevent your app from working on multitasking mode which may or not be acceptable.

You should have to use Date.ParseExact or Date.TryParseExact with correct format string.

 Dim edate = "10/12/2009"
 Dim expenddt As Date = Date.ParseExact(edate, "dd/MM/yyyy", 
            System.Globalization.DateTimeFormatInfo.InvariantInfo)

OR

 Dim format() = {"dd/MM/yyyy", "d/M/yyyy", "dd-MM-yyyy"}
 Dim expenddt As Date = Date.ParseExact(edate, format,  
     System.Globalization.DateTimeFormatInfo.InvariantInfo, 
     Globalization.DateTimeStyles.None)

OR

Dim format() = {"dd/MM/yyyy", "d/M/yyyy", "dd-MM-yyyy"}
Dim expenddt As Date
Date.TryParseExact(edate, format, 
    System.Globalization.DateTimeFormatInfo.InvariantInfo, 
    Globalization.DateTimeStyles.None, expenddt)

Try This. You need pass the authentication to let the server know its a valid user. You need to import these two packages and has to include a jersy jar. If you dont want to include jersy jar then import this package

import sun.misc.BASE64Encoder;

import com.sun.jersey.core.util.Base64;
import sun.net.www.protocol.http.HttpURLConnection;

and then,

String encodedAuthorizedUser = getAuthantication("username", "password");
URL url = new URL("Your Valid Jira URL");
HttpURLConnection httpCon = (HttpURLConnection) url.openConnection();
httpCon.setRequestProperty ("Authorization", "Basic " + encodedAuthorizedUser );

 public String getAuthantication(String username, String password) {
   String auth = new String(Base64.encode(username + ":" + password));
   return auth;
 }

Here's another approach.

git checkout {SOURCE_BRANCH}               # switch to Source branch.
git checkout {COMMIT_HASH}                 # go back to the desired commit.
git checkout -b {temp_branch}              # create a new temporary branch from {COMMIT_HASH} snapshot.
git checkout {TARGET_BRANCH}               # switch to Target branch.
git merge {temp_branch}                    # merge code to your Target branch.
git branch -d {temp_branch}                # delete the temp branch.

Just give a try using subset

nrow(subset(data,condition))

Example

nrow(subset(myData,sCode == "CA"))

i use this commands

wget -q -O /dev/null "http://example.com/some/cron/job.php" > /dev/null 2>&1

Cron task:

* * * * * wget -q -O /dev/null "http://example.com/some/cron/job.php" > /dev/null 2>&1

I will add a StackBlitz example and a comment to the answer from @tahiche.

The return value is a function to remove the event listener after you have added it. It is considered good practice to remove event listeners when you don't need them anymore. So you can store this return value and call it inside your ngOnDestroy method.

I admit that it might seem confusing at first, but it is actually a very useful feature. How else can you clean up after yourself?

export class MyComponent implements OnInit, OnDestroy {

  public removeEventListener: () => void;

  constructor(
    private renderer: Renderer2, 
    private elementRef: ElementRef
  ) {
  }

  public ngOnInit() {
    this.removeEventListener = this.renderer.listen(this.elementRef.nativeElement, 'click', (event) => {
      if (event.target instanceof HTMLAnchorElement) {
        // Prevent opening anchors the default way
        event.preventDefault();
        // Your custom anchor click event handler
        this.handleAnchorClick(event);
      }
    });
  }

  public ngOnDestroy() {
    this.removeEventListener();
  }
}

You can find a StackBlitz here to show how this could work for catching clicking on anchor elements.

I added a body with an image as follows:
<img src="x" onerror="alert(1)"></div>
to show that the sanitizer is doing its job.

Here in this fiddle you find the same body attached to an innerHTML without sanitizing it and it will demonstrate the issue.

This is documented behavior, why do you run CHECKIDENT if you recreate the table, in that case skip the step or use TRUNCATE (if you don't have FK relationships)

var elementCheckBox = document.getElementById("IdOfCheckBox");_x000D_
_x000D_
_x000D_
elementCheckBox[0].checked //return true if checked and false if not checked

Office 2007 is 32 bit only so there is no issue there. Your problems arise only with Office 64 bit which has both 32 and 64 bit versions.

You cannot hope to support users with 64 bit Office 2010 when you only have Office 2007. The solution is to upgrade.

If the only Declare that you have is that ShellExecute then you won't have much to do once you get hold of 64 bit Office, but it's not really viable to support users when you can't run the program that you ship! Just think what you would do you do when they report a bug?

Try this function, which also displays variable names for the correlation matrix:

def plot_corr(df,size=10):
    '''Function plots a graphical correlation matrix for each pair of columns in the dataframe.

    Input:
        df: pandas DataFrame
        size: vertical and horizontal size of the plot'''

    corr = df.corr()
    fig, ax = plt.subplots(figsize=(size, size))
    ax.matshow(corr)
    plt.xticks(range(len(corr.columns)), corr.columns);
    plt.yticks(range(len(corr.columns)), corr.columns);

You may want to also look into using Task instead of background workers.

The easiest way to do this is in your example is Task.Run(InitializationThread);.

There are several benefits to using tasks instead of background workers. For example, the new async/await features in .net 4.5 use Task for threading. Here is some documentation about Task https://docs.microsoft.com/en-us/dotnet/api/system.threading.tasks.task

Use function array_unshift

Yes. It is possible :D

SELECT  SUM(totalHours) totalHours
FROM
        ( 
            select sum(hours) totalHours from resource
            UNION ALL
            select sum(hours) totalHours from projects-time
        ) s

As a sidenote, the tablename projects-time must be delimited to avoid syntax error. Delimiter symbols vary on RDBMS you are using.

Let's define a list first:

lst=[1,2,3]

You can directly write your list to a file:

f=open("filename.txt","w")
f.write(str(lst))
f.close()

To read your list from text file first you read the file and store in a variable:

f=open("filename.txt","r")
lst=f.read()
f.close()

The type of variable lst is of course string. You can convert this string into array using eval function.

lst=eval(lst)

It is and old question but let me add a detail just in case more people like me arrive here.

The excellent answer posted by Brian is not working for me in Jelly Bean. I have to add also:

browser.setInitialScale(30);

The parameter can be any percentage tha accomplishes that the resized content is smaller than the webview width. Then setUseWideViewPort(true) extends the content width to the maximum of the webview width.

Right click on the .svc file in Solution Explorer and click View Markup

 <%@ ServiceHost Language="C#" Debug="true" 
     Service="MyService.**GetHistoryInfo**" 
     CodeBehind="GetHistoryInfo.svc.cs" %>

Update the service reference where you are referring to.

For example, if you want the date format to be "03.11.2017"

 if (String.valueOf(DateEdit.getText()).matches("([1-9]{1}|[0]{1}[1-9]{1}|[1]{1}[0-9]{1}|[2]{1}[0-9]{1}|[3]{1}[0-1]{1})" +
           "([.]{1})" +
           "([0]{1}[1-9]{1}|[1]{1}[0-2]{1}|[1-9]{1})" +
           "([.]{1})" +
           "([20]{2}[0-9]{2})"))
           checkFormat=true;
 else
           checkFormat=false;

 if (!checkFormat) {
 Toast.makeText(getApplicationContext(), "incorrect date format! Ex.23.06.2016", Toast.LENGTH_SHORT).show();
                }

My issue was also caused by missing https binding in IIS: Selected default website > On the far right pane selected Bindings > add > https

Choose 'IIS Express Development Certificate' and set port to 443

You could also use the stringr package:

library(stringr)
str_length("foo")
[1] 3

• Well, first System.exit(0) is used to terminate the program and having statements below it is not correct, although the compiler does not throw any errors.
• a plain return; is used in a method of void return type to return the control of execution to its parent method.

I know it is a bit late to answer this question, but it is the first entry in google, so I think it is worth to answer it.

The problem is not a coding problem, it is an architecture problem.

You have created an interface class Event: public Item to define the methods which all events should implement. Then you have defined two types of events which inherits from class Event: public Item; Arrival and Landing and then, you have added a method Landing* createNewLanding(Arrival* arrival); from the landing functionality in the class Event: public Item interface. You should move this method to the class Landing: public Event class because it only has sense for a landing. class Landing: public Event and class Arrival: public Event class should know class Event: public Item but event should not know class Landing: public Event nor class Arrival: public Event.

I hope this helps, regards, Alberto

You can use the Calendar class to convert Date

public long getDifference()
{
    SimpleDateFormat sdf = new SimpleDateFormat("EEE MMM dd kk:mm:ss z yyyy");
    Date d = sdf.parse("Mon May 27 11:46:15 IST 2013");

    Calendar c = Calendar.getInstance();
    c.setTime(d);
    long time = c.getTimeInMillis();
    long curr = System.currentTimeMillis();
    long diff = curr - time;    //Time difference in milliseconds
    return diff/1000;
}

The question is already answered but I wanted to point out another solution which is fast and works if length is not meant to be changed at run-time. Use macro #define before main() to define length and in main() your initialization will work:

#define length 10

int main()
{
    int boardAux[length][length] = {{0}};
}

Macros are run before the actual compilation and length will be a compile-time constant (as referred by David Rodríguez in his answer). It will actually substitute length with 10 before compilation.

An extremely important consideration in the choice of Expression vs Func is that IQueryable providers like LINQ to Entities can 'digest' what you pass in an Expression, but will ignore what you pass in a Func. I have two blog posts on the subject:

Something that is now available in maven as well is

mvn goal --no-snapshot-updates

or in short

mvn goal -nsu

Try this:

^[A-Za-z ].*

list = [1, 2, 3, 4, 5]
for i in list[0:-1]:
    print(i, end=', ')
print(list[-1])

do for loops really take that much longer to run?

was trying to make something that printed all str values in a list separated by commas, inserting "and" before the last entry and came up with this:

spam = ['apples', 'bananas', 'tofu', 'cats']
for i in spam[0:-1]:
    print(i, end=', ')
print('and ' + spam[-1])

You're passing the same model to the partial view as is being passed to the main view, and they are different types. The model is a DbSet of Notes, where you need to pass in a single Note.

You can do this by adding a parameter, which I'm guessing as it's the create form would be a new Note

@Html.Partial("_CreateNote", new QuickNotes.Models.Note())

Jeff has a post about it, otherwise I found some useful documents on Apple's website, in Cocoa tutorials (this one for example).

var Test = React.createClass({
     add: function(event){
         if(event.key === 'Enter'){
            alert('Adding....');
         }
     },
     render: function(){
        return(
           <div>
            <input type="text" id="one" onKeyPress={(event) => this.add(event)}/>    
          </div>
        );
     }
});

Try this
class Program { static void Main(string[] args) {

        getfiles get = new getfiles();
        List<string> files =  get.GetAllFiles(@"D:\Rishi");

        foreach(string f in files)
        {
            Console.WriteLine(f);
        }


        Console.Read();
    }


}

class getfiles
{
    public List<string> GetAllFiles(string sDirt)
    {
        List<string> files = new List<string>();

        try
        {
            foreach (string file in Directory.GetFiles(sDirt))
            {
                files.Add(file);
            }
            foreach (string fl in Directory.GetDirectories(sDirt))
            {
                files.AddRange(GetAllFiles(fl));
            }
        }
        catch (Exception ex)
        {

            Console.WriteLine(ex.Message);
        }



        return files;
    }
}

iOS 5 now supports HTML5 better. in your webapp do

<input type="date" name="date" />

Android as of 4.0 lacks this type of native menu support.

List<WebElement> myElements = driver.findElements(By.xpath("some/path//a"));
        System.out.println("Size of List: "+myElements.size());
        for(WebElement e : myElements) 
        {        
            System.out.print("Text within the Anchor tab"+e.getText()+"\t");
            System.out.println("Anchor: "+e.getAttribute("href"));
        }

//NOTE: "//a" will give you all the anchors there on after the point your XPATH has reached.

While it may work on some platforms, be aware that platform.architecture is not always a reliable way to determine whether python is running in 32-bit or 64-bit. In particular, on some OS X multi-architecture builds, the same executable file may be capable of running in either mode, as the example below demonstrates. The quickest safe multi-platform approach is to test sys.maxsize on Python 2.6, 2.7, Python 3.x.

$ arch -i386 /usr/local/bin/python2.7
Python 2.7.9 (v2.7.9:648dcafa7e5f, Dec 10 2014, 10:10:46)

The Run/Debug configuration you're using is meant to let you run Maven on your workspace as if from the command line without leaving Eclipse.

JSFIDDEL DEMO

using javascript

?document.getElementById('sel').value = 'car';??????????

using jQuery

$('#sel').val('car');

The noConflict() method releases the $ shortcut identifier, so that other scripts can use it for next time.

Default jquery $ as:

// Actin  with $
$(function(){
    $(".add").hide();
    $(".add2").show();
});

Or as custom:

var j = jQuery.noConflict();
 // Action with j
j(function(){
    j(".edit").hide();
    j(".add2").show();
});

You need to add style="overflow-y:scroll;" to the div tag. (This will force a scrollbar on the vertical).

If you only want a scrollbar when needed, just do overflow-y:auto;

A smart pointer is a class, a wrapper of a normal pointer. Unlike normal pointers, smart point’s life circle is based on a reference count (how many time the smart pointer object is assigned). So whenever a smart pointer is assigned to another one, the internal reference count plus plus. And whenever the object goes out of scope, the reference count minus minus.

Automatic pointer, though looks similar, is totally different from smart pointer. It is a convenient class that deallocates the resource whenever an automatic pointer object goes out of variable scope. To some extent, it makes a pointer (to dynamically allocated memory) works similar to a stack variable (statically allocated in compiling time).

Necromancing here.
Obviously, x *= -1; is far too simple.

Instead, we could use a trivial binary complement:

number = ~(number - 1) ;

Like this:

import java.io.*;

/* Name of the class has to be "Main" only if the class is public. */
class Ideone
{
    public static void main (String[] args) throws java.lang.Exception
    {
        int iPositive = 15;
        int iNegative = ( ~(iPositive - 1) ) ; // Use extra brackets when using as C preprocessor directive ! ! !...
        System.out.println(iNegative);

        iPositive =  ~(iNegative - 1)  ;
        System.out.println(iPositive);

        iNegative = 0;
        iPositive = ~(iNegative - 1);
        System.out.println(iPositive);


    }
}

That way we can ensure that mediocre programmers don't understand what's going on ;)

Here's a small improvement that to @UltraInstinct's Tee class, modified to be a context manager and also captures any exceptions.

import traceback
import sys

# Context manager that copies stdout and any exceptions to a log file
class Tee(object):
    def __init__(self, filename):
        self.file = open(filename, 'w')
        self.stdout = sys.stdout

    def __enter__(self):
        sys.stdout = self

    def __exit__(self, exc_type, exc_value, tb):
        sys.stdout = self.stdout
        if exc_type is not None:
            self.file.write(traceback.format_exc())
        self.file.close()

    def write(self, data):
        self.file.write(data)
        self.stdout.write(data)

    def flush(self):
        self.file.flush()
        self.stdout.flush()

To use the context manager:

print("Print")
with Tee('test.txt'):
    print("Print+Write")
    raise Exception("Test")
print("Print")

Note that it is not possible to use HTML in the message body, according to RFC 2368:

The special hname "body" indicates that the associated hvalue is the body of the message. The "body" hname should contain the content for the first text/plain body part of the message. The mailto URL is primarily intended for generation of short text messages that are actually the content of automatic processing (such as "subscribe" messages for mailing lists), not general MIME bodies.

It took me a little while to figure out how to disable draggable on drop—use ui.draggable to reference the object being dragged from inside the drop function:

$("#drop-target").droppable({
    drop: function(event, ui) {
        ui.draggable.draggable("disable", 1); // *not* ui.draggable("disable", 1);
        …
    }
});

You need to call Toast.makeText(...) from the UI thread:

activity.runOnUiThread(new Runnable() {
  public void run() {
    Toast.makeText(activity, "Hello", Toast.LENGTH_SHORT).show();
  }
});

This is copy-pasted from another (duplicate) SO answer.

In my opinion the bare minimum implementation has two requirements. A state that keeps track of whether the modal is open or not, and a portal to render the modal outside of the standard react tree.

The ModalContainer component below implements those requirements along with corresponding render functions for the modal and the trigger, which is responsible for executing the callback to open the modal.

import React from 'react';
import PropTypes from 'prop-types';
import Portal from 'react-portal';

class ModalContainer extends React.Component {
  state = {
    isOpen: false,
  };

  openModal = () => {
    this.setState(() => ({ isOpen: true }));
  }

  closeModal = () => {
    this.setState(() => ({ isOpen: false }));
  }

  renderModal() {
    return (
      this.props.renderModal({
        isOpen: this.state.isOpen,
        closeModal: this.closeModal,
      })
    );
  }

  renderTrigger() {
     return (
       this.props.renderTrigger({
         openModal: this.openModal
       })
     )
  }

  render() {
    return (
      <React.Fragment>
        <Portal>
          {this.renderModal()}
        </Portal>
        {this.renderTrigger()}
      </React.Fragment>
    );
  }
}

ModalContainer.propTypes = {
  renderModal: PropTypes.func.isRequired,
  renderTrigger: PropTypes.func.isRequired,
};

export default ModalContainer;

And here's a simple use case...

import React from 'react';
import Modal from 'react-modal';
import Fade from 'components/Animations/Fade';
import ModalContainer from 'components/ModalContainer';

const SimpleModal = ({ isOpen, closeModal }) => (
  <Fade visible={isOpen}> // example use case with animation components
    <Modal>
      <Button onClick={closeModal}>
        close modal
      </Button>
    </Modal>
  </Fade>
);

const SimpleModalButton = ({ openModal }) => (
  <button onClick={openModal}>
    open modal
  </button>
);

const SimpleButtonWithModal = () => (
   <ModalContainer
     renderModal={props => <SimpleModal {...props} />}
     renderTrigger={props => <SimpleModalButton {...props} />}
   />
);

export default SimpleButtonWithModal;

I use render functions, because I want to isolate state management and boilerplate logic from the implementation of the rendered modal and trigger component. This allows the rendered components to be whatever you want them to be. In your case, I suppose the modal component could be a connected component that receives a callback function that dispatches an asynchronous action.

If you need to send dynamic props to the modal component from the trigger component, which hopefully doesn't happen too often, I recommend wrapping the ModalContainer with a container component that manages the dynamic props in its own state and enhance the original render methods like so.

import React from 'react'

The SqlDataReader is a valid data source for the DataTable. As such, all you need to do its this:

public DataTable GetData()
{
    SqlConnection conn = new SqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings["BarManConnectionString"].ConnectionString);
    conn.Open();
    string query = "SELECT * FROM [EventOne]";
    SqlCommand cmd = new SqlCommand(query, conn);

    DataTable dt = new DataTable();
    dt.Load(cmd.ExecuteReader());
    conn.Close();
    return dt;
}

put x=0 outside the for loop that is the problem

Please use sorted() function in Python3

items = ["love", "like", "play", "cool", "my"]
sorted(items2)

If you want to delete a specific extension recursively, use this:

For /R "C:\Users\Desktop\saleh" %G IN (*.ppt) do del "%G"

You can do

df['column'] = None #This works. This will create a new column with None type
df.column = None #This will work only when the column is already present in the dataframe 

On my blog, the reason of this error is a plugin named Broken Link checker. This plugin has high resource usage from hosting, resulting in this error.

Check if a plugin on your installation is behaving similarly like this.

Let's say you have a collection named $services that you are passing to the view.

If you need a JS array with the names, you can iterate over this as follows:

<script>
    const myServices = [];
    @foreach ($services as $service)
        myServices.push('{{ $service->name }}');
    @endforeach
</script>

Note: If the string has special characters (like ó or HTML code), you can use {!! $service->name !!}.

If you need an array of objects (with all of the attributes), you can use:

<script>
  const myServices = @json($services);
  // ...
</script>

Note: This blade directive @json is not available for old Laravel versions. You can achieve the same result using json_encode as described in other answers.

Sometimes you don't need to pass a complete collection to the view, and just an array with 1 attribute. If that's your case, you better use $services = Service::pluck('name'); in your Controller.

For CMD one line LF-only:

powershell -NoProfile -command "((Get-Content 'prueba1.txt') -join \"`n\") + \"`n\" | Set-Content -NoNewline 'prueba1.txt'"

so you can create a .bat

Yes, it prints GARBAGE unless you are lucky.

VERY IMPORTANT.

The type of the printf/sprintf/fprintf argument MUST match the associated format type char.

If the types don't match and it compiles, the results are very undefined.

Many newer compilers know about printf and issue warnings if the types do not match. If you get these warnings, FIX them.

If you want to convert types for arguments for variable functions, you must supply the cast (ie, explicit conversion) because the compiler can't figure out that a conversion needs to be performed (as it can with a function prototype with typed arguments).

printf("%d\n", (int) ch)

In this example, printf is being TOLD that there is an "int" on the stack. The cast makes sure that whatever thing sizeof returns (some sort of long integer, usually), printf will get an int.

printf("%d", (int) sizeof('\n'))

Rather than a brute force loop through the list (eg 1 to 10000), rather use an iterative search approach : The List needs to be sorted by the element to be tested.

Start search at the middle element size()/2 eg 5000 if search item greater than element at 5000, then test the element at the midpoint between the upper(10000) and midpoint(5000) - 7500

keep doing this until you reach the match (or use a brute force loop through once you get down to a smaller range (eg 20 items)

You can search a list of 10000 in around 13 to 14 tests, rather than potentially 9999 tests.

I have been doing it this way:

.element {
    overflow-y: visible;
}

Painfully simple I know...

This error also happens if you're using a self-signed certificate with a keyUsage missing the value keyCertSign.

Or add "sort name" to list alphabetically

Get-ADPrincipalGroupMembership username | select name | sort name

You are missing a closing h2 tag. It should be:

<h2><!-- Content --></h2> 

var bottom = $('#bottom').position().top + $('#bottom').height();

How to install Python / Pip on Windows Steps

1. Visit the official Python download page and grab the Windows installer for the latest version of Python 3. python.org/downloads/

2. Run the installer. Be sure to check the option to add Python to your PATH while installing.

3. Open PowerShell as admin by right clicking on the PowerShell icon and selecting ‘Run as Admin’

4. To solve permission issues, run the following command:

Set-ExecutionPolicy Unrestricted

5. Next, set the system’s PATH variable to include directories that include Python components and packages we’ll add later. To do this: C:\Python35-32;C:\Python35-32\Lib\site-packages\;C:\Python35-32\Scripts\

6. download the bootstrap scripts for easy_install and pip from https://bootstrap.pypa.io/ ez_setup.py get-pip.py

7. Save both the files in Python Installed folder Go to Python folder and run following: Python ez_setup.py Python get-pip.py

8. To create a Virtual Environment, use the following commands:

cd c:\python pip install virtualenv virtualenv test .\test\Scripts\activate.ps1 pip install IPython ipython3 Now You can install any Python package with pip

That’s it !! happy coding Visit This link for Easy steps of Installation python and pip in windows http://rajendralora.com/?p=183

If you want to calculate the zscore for all of the columns, you can just use the following:

df_zscore = (df - df.mean())/df.std()

Jonathan from the ExcelCentral forums suggests:

=WEEKNUM(A1,2)-WEEKNUM(DATE(YEAR(A1),MONTH(A1),1),2)+1 

This formula extracts the week of the year [...] and then subtracts it from the week of the first day in the month to get the week of the month. You can change the day that weeks begin by changing the second argument of both WEEKNUM functions (set to 2 [for Monday] in the above example). For weeks beginning on Sunday, use:

=WEEKNUM(A1,1)-WEEKNUM(DATE(YEAR(A1),MONTH(A1),1),1)+1

For weeks beginning on Tuesday, use:

=WEEKNUM(A1,12)-WEEKNUM(DATE(YEAR(A1),MONTH(A1),1),12)+1

etc.

I like it better because it's using the built in week calculation functionality of Excel (WEEKNUM).

Go into your AndroidManifest.xml file

• Click on the Application Tab
• Find the Text Box Labelled "Icon"
• Then click the "Browse" button at the end of the text box
• Click the Button Labelled: "Create New Icon..."
  
  
• Create your icon
• Click Finish
  
• Click "Yes to All" if you already have the icon set to something else.

Enjoy using a gui rather then messing with an image editor! Hope this helps!

<input type="number" step="any">

This worked for me and i think is the easiest way to make the input field accept any decimal number irrespective of how long the decimal part is. Step attribute actually shows the input field how many decimal points should be accepted. E.g, step="0.01" will accept only two decimal points.

I was getting the same error. In the Project Facets of my Java project, the Java compile level was set to 1.7 whereas the WebSphere Application Server v7.0 had a Runtime Composition of JRE v1.6; setting the Java compile level to 1.6 in Project Facets got rid of the error. I did not have to change the Compiler compliance level though, it's still 1.7. Hope this helps!

I think you should use python wheels for distribution instead of egg now.

Wheels are the new standard of python distribution and are intended to replace eggs. Support is offered in pip >= 1.4 and setuptools >= 0.8.

You have to use

<iframe title="YouTube video player" width="480" height="390" src="http://www.youtube.com/embed/zGPuazETKkI?autoplay=1" frameborder="0" allowfullscreen></iframe>

?autoplay=1

and not

&autoplay=1

its the first URL param so its added with a ?

The sample above worked like a charm. I just did a modification just in case I need to manage multiple values. I hope this helps!

app.service('sharedProperties', function () {

    var hashtable = {};

    return {
        setValue: function (key, value) {
            hashtable[key] = value;
        },
        getValue: function (key) {
            return hashtable[key];
        }
    }
});

Another working but ugly solution : colspan="100", where 100 is a value larger than total columns you need to colspan.

According to the W3C, the colspan="0" option is valid only with COLGROUP tag.

By this way, you hold a form by his ID and throw all his content. This technic is fastiest.

document.forms["id_form"].reset();

As mentioned above, you can change the property of the textbox "Read Only" to "True" from the properties window.

How about using FONT tag?

Like:

H<font color="red">E</font>LLO.

Can't show example here, because this site doesn't allow font tag use.

Span style is fast and easy too.
