Docker caches the entire filesystem state after each successful RUN
line.
Knowing that:
RUN
command, comment it out in the Dockerfile (as well as any and all subsequent RUN
commands), then run docker build
and docker run
again.RUN
command, simply add || true
to it to force it to succeed; then proceed like above (keep any and all subsequent RUN
commands commented out, run docker build
and docker run
)Tada, no need to mess with Docker internals or layer IDs, and as a bonus Docker automatically minimizes the amount of work that needs to be re-done.

The other provided solutions are great when you want to add only 2 byte arrays, but if you want to keep appending several byte[] chunks to make a single:
byte[] readBytes ; // Your byte array .... //for eg. readBytes = "TestBytes".getBytes();
ByteArrayBuffer mReadBuffer = new ByteArrayBuffer(0 ) ; // Instead of 0, if you know the count of expected number of bytes, nice to input here
mReadBuffer.append(readBytes, 0, readBytes.length); // this copies all bytes from readBytes byte array into mReadBuffer
// Any new entry of readBytes, you can just append here by repeating the same call.
// Finally, if you want the result into byte[] form:
byte[] result = mReadBuffer.buffer();

You could try using a casting operator to convert it to an integer:
$page = (int) $_GET['p'];
if($page == "")
{
$page = 1;
}
if(empty($page) || !$page)
{
setcookie("error", "Invalid page.", time()+3600);
header("location:somethingwentwrong.php");
die();
}
//else continue with code
This is actually pretty easy in Excel (or any spreadsheet application).
You'll want to use the =CONCATENATE()
function as shown in the formula bar in the following screenshot:
Step 1 involves adding quotes in column B,
Step 2 involves specifying the function and then copying it down column C (by now your spreadsheet should look like the screenshot),
Step 3 (if you need the text outside of the formula) involves copying column C, right-clicking on column D, choosing Paste Special >> Paste Values. Column D should then contain the text that was calculated in column C.

System.out.println("Answer:"+Integer.toHexString(registered));
This answer will give you only string representations what are usually presented in the tables. Jon Skeet's answer explains more.
My similar issue was caused by having special characters (e.g. periods) in the selector.
The fix was to escape the special characters:
$("#dots\\.er\\.bad").val("mmmk");

I've been thinking about this too. From a C background, you can simulate function return code types, as well as, parameter types, using something like the following:
function top_function() {
var rc;
console.log("1st call");
rc = Number(test_function("number", 1, "string", "my string"));
console.log("typeof rc: " + typeof rc + " rc: " + rc);
console.log("2nd call");
rc = Number(test_function("number", "a", "string", "my string"));
console.log("typeof rc: " + typeof rc + " rc: " + rc);
}
function test_function(parm_type_1, parm_val_1, parm_type_2, parm_val_2) {
if (typeof parm_val_1 !== parm_type_1) console.log("Parm 1 not correct type");
if (typeof parm_val_2 !== parm_type_2) console.log("Parm 2 not correct type");
return parm_val_1;
}
The Number before the calling function returns a Number type regardless of the type of the actual value returned, as seen in the 2nd call where typeof rc = number but the value is NaN
the console.log for the above is:
1st call
typeof rc: number rc: 1
2nd call
Parm 1 not correct type
typeof rc: number rc: NaN

If you want to $broadcast
use the $rootScope
:
$scope.startScanner = function() {
$rootScope.$broadcast('scanner-started');
}
And then to receive, use the $scope
of your controller:
$scope.$on('scanner-started', function(event, args) {
// do what you want to do
});
If you want you can pass arguments when you $broadcast
:
$rootScope.$broadcast('scanner-started', { any: {} });
And then receive them:
$scope.$on('scanner-started', function(event, args) {
var anyThing = args.any;
// do what you want to do
});
Documentation for this inside the Scope docs.
timestamp is an object
timestamp= {nanoseconds: 0,_x000D_

Diff with the following options would do a binary comparison to check just if the files are different at all and it'd output if the files are the same as well:
diff -qs {file1} {file2}
If you are comparing two files with the same name in different directories, you can use this form instead:
diff -qs {file1} --to-file={dir2}

If you want to content to be scrollable, set the position of the content to absolute:
content {
position: absolute;
...
}
I don't know if this was just for me, but if not that's the fix!
Also since the background is fixed, it means you have a "parallax" effect! So now, not only did this person teach you how to make a blurry background, but it is also a parallax background effect!
Not sure exactly what your after, but I think I get it.
A header - stays at the top of the screen? A footer - stays at the bottom of the screen? Content area -> fits the space between the footer and the header?
You can do this by absolute positioning or with fixed positioning.
Here is an example with absolute positioning: http://jsfiddle.net/FMYXY/1/
Markup:
<div class="header">Header</div>
<div class="mainbody">Main Body</div>
<div class="footer">Footer</div>
CSS:
.header {outline:1px solid red; height: 40px; position:absolute; top:0px; width:100%;}
.mainbody {outline:1px solid green; min-height:200px; position:absolute; top:40px; width:100%; height:90%;}
.footer {outline:1px solid blue; height:20px; position:absolute; height:25px;bottom:0; width:100%; }
To make it work best, I'd suggest using % instead of pixels, as you will run into problems with different screen/device sizes.
This will make the div fixed at the bottom of the page but in case the page is long it will only be visible when you scroll down.
<style type="text/css">
#footer {
position : absolute;
bottom : 0;
height : 40px;
margin-top : 40px;
}
</style>
<div id="footer">I am footer</div>
The height and margin-top should be the same so that the footer doesnt show over the content.
Use DecimalFormat
double answer = 5.0;
DecimalFormat df = new DecimalFormat("###.#");
System.out.println(df.format(answer));
You forgot to close the mysql_query command:
mysql_query("INSERT INTO users (first, last, whenadded) VALUES ('$first', '$last', now())"
);
Note that last parentheses.
In Angular 6, with your router you can use:
RouterModule.forRoot(routes, { useHash: false })
Another option; use invoke-command
:
cls
$cred = Get-Credential
$server = 'MyRemoteComputer'
$service = 'My Service Name'
invoke-command -Credential $cred -ComputerName $server -ScriptBlock {
param(
[Parameter(Mandatory=$True,Position=0)]
[string]$service
)
stop-service $service
} -ArgumentList $service
NB: to use this option you'll need PowerShell to be installed on the remote machine and for the firewall to allow requests through, and for the Windows Remote Management service to be running on the target machine. You can configure the firewall by running the following script directly on the target machine (one off task): Enable-PSRemoting -force
.
You can use %~dp0
, d means the drive only, p means the path only, 0 is the argument for the full filename of the batch file.
For example if the file path was C:\Users\Oliver\Desktop\example.bat then the argument would equal C:\Users\Oliver\Desktop\, also you can use the command set cpath=%~dp0 && set cpath=%cpath:~0,-1%
and use the %cpath%
variable to remove the trailing slash.

If you want to analyze, repair and optimize all tables in all databases in your MySQL server, you can do this in one go from the command line. You will need root to do that though.
mysqlcheck -u root -p --auto-repair --optimize --all-databases
Once you run that, you will be prompted to enter your MySQL root password. After that, it will start and you will see results as it's happening.
Example output:
yourdbname1.yourdbtable1 OK
yourdbname2.yourdbtable2 Table is already up to date
yourdbname3.yourdbtable3
note : Table does not support optimize, doing recreate + analyze instead
status : OK
etc..
etc...
Repairing tables
yourdbname10.yourdbtable10
warning : Number of rows changed from 121378 to 81562
status : OK
If you don't know the root password and are using WHM, you can change it from within WHM by going to: Home > SQL Services > MySQL Root Password

Just for the sake of completeness: there are IPv4-mapped IPv6 addresses, where you can embed an IPv4 address in an IPv6 address (may not be supported by every IPv6 equipment).
Example: I run a server on my machine, which can be accessed via http://127.0.0.1:19983/solr
. If I access it via an IPv4-mapped IPv6 address then I access it via http://[::ffff:127.0.0.1]:19983/solr
(which will be converted to http://[::ffff:7f00:1]:19983/solr
)
maybe this help :
declare

,@text1 varchar(50)='hello'
,@text2 varchar(50)='world'
set @statement = '

'
exec sp_executesql @statement;
this is same as below :
select @text1 + ' beautifull ' + @text2
Summary: If you only want to create a few columns, use df[['new_col1','new_col2']] = df[['data1','data2']].apply( function_of_your_choosing(x), axis=1)
For this solution, the number of new columns you are creating must be equal to the number columns you use as input to the .apply() function. If you want to do something else, have a look at the other answers.
Details Let's say you have two-column dataframe. The first column is a person's height when they are 10; the second is said person's height when they are 20.
Suppose you need to calculate both the mean of each person's heights and sum of each person's heights. That's two values per each row.
You could do this via the following, soon-to-be-applied function:
def mean_and_sum(x):
"""
Calculates the mean and sum of two heights.
Parameters:
:x -- the values in the row this function is applied to. Could also work on a list or a tuple.
"""
sum=x[0]+x[1]
mean=sum/2
return [mean,sum]
You might use this function like so:
df[['height_at_age_10','height_at_age_20']].apply(mean_and_sum(x),axis=1)
(To be clear: this apply function takes in the values from each row in the subsetted dataframe and returns a list.)
However, if you do this:
df['Mean_&_Sum'] = df[['height_at_age_10','height_at_age_20']].apply(mean_and_sum(x),axis=1)
you'll create 1 new column that contains the [mean,sum] lists, which you'd presumably want to avoid, because that would require another Lambda/Apply.
Instead, you want to break out each value into its own column. To do this, you can create two columns at once:
df[['Mean','Sum']] = df[['height_at_age_10','height_at_age_20']]
.apply(mean_and_sum(x),axis=1)
Send params from View to an other View, from Sender View to Receiver View use viewParam and includeViewParams=true
In Sender
Sender.xhtml
<f:metadata>
<f:viewParam name="ID" value="#{senderMB._strID}" />
</f:metadata>
“includeViewParams=true”
in return String of click button event
Click button fire senderMB.clickBtnDetail(dto) with dto from senderMB._arrDataSender.xhtml
<p:dataTable rowIndexVar="index" id="dataTale"value="#{senderMB._arrData}" var="dto">
<p:commandButton action="#{senderMB.clickBtnDetail(dto)}" value="??"
ajax="false"/>
</p:dataTable>
In senderMB.clickBtnDetail(dto) we assign _strID with argument we got from button event (dto), here this is Sender_DTO and assign to senderMB._strID
Sender_MB.java
public String clickBtnDetail(sender_DTO sender_dto) {
this._strID = sender_dto.getStrID();
return "Receiver?faces-redirect=true&includeViewParams=true";
}
The link when clicked will become http://localhost:8080/my_project/view/Receiver.xhtml?*ID=12345*
In Recever
Receiver.xhtml
<f:metadata><f:viewParam name="ID" value="#{receiver_MB._strID}"/></f:metadata>
It will get param ID from sender View and assign to receiver_MB._strID
Receiver.xhtml
<f:event listener="#{receiver_MB.preRenderView}" type="preRenderView" />
into f:metadata tag
Receiver.xhtml
<f:metadata>
<f:viewParam name="ID" value="#{receiver_MB._strID}" />
<f:event listener="#{receiver_MB.preRenderView}"
type="preRenderView" />
</f:metadata>
Now we want to use this param in our read database method, it is available to use
Receiver_MB.java
public void preRenderView(ComponentSystemEvent event) throws Exception {
if (FacesContext.getCurrentInstance().isPostback()) {
return;
}
readFromDatabase();
}
private void readFromDatabase() {
//use _strID to read and set property
}

There is one very interesting application by Stéphane Sudre which does all of this for you, is scriptable / supports building from the command line, has a super nice GUI and is FREE. Sad thing is: it's called "Packages" which makes it impossible to find in google.

I wished I had known about it before I started handcrafting my own scripts.
I have created a module specifically designed for command-line JSON manipulation:
https://github.com/ddopson/underscore-cli
It allows you to do powerful things really easily:
cat earthporn.json | underscore select '.data .title'
# [ 'Fjaðrárgljúfur canyon, Iceland [OC] [683x1024]',
# 'New town, Edinburgh, Scotland [4320 x 3240]',
# 'Sunrise in Bryce Canyon, UT [1120x700] [OC]',
# ...
# 'Kariega Game Reserve, South Africa [3584x2688]',
# 'Valle de la Luna, Chile [OS] [1024x683]',
# 'Frosted trees after a snowstorm in Laax, Switzerland [OC] [1072x712]' ]
cat earthporn.json | underscore select '.data .title' | underscore count
# 25
underscore map --data '[1, 2, 3, 4]' 'value+1'
# prints: [ 2, 3, 4, 5 ]
underscore map --data '{"a": [1, 4], "b": [2, 8]}' '_.max(value)'
# [ 4, 8 ]
echo '{"foo":1, "bar":2}' | underscore map -q 'console.log("key = ", key)'
# key = foo
# key = bar
underscore pluck --data "[{name : 'moe', age : 40}, {name : 'larry', age : 50}, {name : 'curly', age : 60}]" name
# [ 'moe', 'larry', 'curly' ]
underscore keys --data '{name : "larry", age : 50}'
# [ 'name', 'age' ]
underscore reduce --data '[1, 2, 3, 4]' 'total+value'
# 10
And it has one of the best "smart-whitespace" JSON formatters available:
If you have any feature requests, comment on this post or add an issue in github. I'd be glad to prioritize features that are needed by members of the community.
It is just a matter time for me. A few milliseconds lost of my life every time I have to press the Shift key before every time I'm able to type "
.
I prefer '
simply because you don't have to do it!
Other than that, you can escape a '
inside single quotes with backslash \'
.
console.log('Don\'t lose time'); // "Don't lose time"
There are two steps here:
X$newdate <- strptime(as.character(X$date), "%d/%m/%Y")
Now the newdate
column should be of type Date
.
format()
or strftime()
:format(X$newdate, "%Y-%m-%d")
A more complete example:
R> nzd <- data.frame(date=c("31/08/2011", "31/07/2011", "30/06/2011"),
+ mid=c(0.8378,0.8457,0.8147))
R> nzd
date mid
1 31/08/2011 0.8378
2 31/07/2011 0.8457
3 30/06/2011 0.8147
R> nzd$newdate <- strptime(as.character(nzd$date), "%d/%m/%Y")
R> nzd$txtdate <- format(nzd$newdate, "%Y-%m-%d")
R> nzd
date mid newdate txtdate
1 31/08/2011 0.8378 2011-08-31 2011-08-31
2 31/07/2011 0.8457 2011-07-31 2011-07-31
3 30/06/2011 0.8147 2011-06-30 2011-06-30
R>
The difference between columns three and four is the type: newdate
is of class Date
whereas txtdate
is character.
NVL and COALESCE are used to achieve the same functionality of providing a default value in case the column returns a NULL.
The differences are:
Examples for the third case. Other cases are simple.
select nvl('abc',10) from dual;
would work as NVL will do an implicit conversion of numeric 10 to string.
select coalesce('abc',10) from dual;
will fail with Error - inconsistent datatypes: expected CHAR got NUMBER
Example for UNION use-case
SELECT COALESCE(a, sysdate)
from (select null as a from dual
union
select null as a from dual
);
fails with ORA-00932: inconsistent datatypes: expected CHAR got DATE
SELECT NVL(a, sysdate)
from (select null as a from dual
union
select null as a from dual
) ;
succeeds.
More information : http://www.plsqlinformation.com/2016/04/difference-between-nvl-and-coalesce-in-oracle.html
You can use the :checkbox
and :checked
pseudo-selectors and the .class
selector, with that you will make sure that you are getting the right elements, only checked checkboxes with the class you specify.
Then you can easily use the Traversing/map method to get an array of values:
var values = $('input:checkbox:checked.group1').map(function () {
return this.value;
}).get(); // ["18", "55", "10"]

this problem is related to the following location:

Changed made to solve it are below
I change the respective name to namespace
@XmlAccessorType(XmlAccessType.FIELD) @XmlType(**name** =
"Kat_getgroupsearch", propOrder = {
@XmlAccessorType(XmlAccessType.FIELD) @XmlType(namespace =
"Kat_getgroupsearch", propOrder = {
@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(**name** = "Kat_getgroupsearchResponse0", propOrder = {
@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(namespace = "Kat_getgroupsearchResponse0", propOrder = {
why?
As written in error log two classes have same name so we should use namespace because XML namespaces are used for providing uniquely named elements and attributes in an XML document.
I really like @luke-schafer's prototype idea, but also hear what he is saying about the issues with prototypes. What about using a simple function?
function sortKeysAndDo( obj, worker ) {_x000D_
var keys = Object.keys(obj);_x000D_
keys.sort();_x000D_
for (var i = 0; i < keys.length; i++) {_x000D_
worker(keys[i], obj[keys[i]]);_x000D_
}_x000D_
}_x000D_
_x000D_
function show( key, value ) {_x000D_
document.write( key + ' : ' + value +'<br>' );_x000D_
}_x000D_
_x000D_
var a = new Array();_x000D_
a['b'] = 1;_x000D_
a['z'] = 1;_x000D_
a['a'] = 1;_x000D_
_x000D_
sortKeysAndDo( a, show);_x000D_
_x000D_
var my_object = { 'c': 3, 'a': 1, 'b': 2 };_x000D_
_x000D_
sortKeysAndDo( my_object, show);
_x000D_
This seems to eliminate the issues with prototypes and still provide a sorted iterator for objects. I am not really a JavaScript guru, though, so I'd love to know if this solution has hidden flaws I missed.
If node-soap
doesn't work for you, just use node
request
module and then convert the xml to json if needed.
My request wasn't working with node-soap
and there is no support for that module beyond the paid support, which was beyond my resources. So i did the following:
curl http://192.168.0.28:10005/MainService/WindowsService?wsdl > wsdl_file.xml
File > New Soap project
and uploaded my wsdl_file.xml
.Show Request Editor
.From there I could send a request and make sure it worked and I could also use the Raw
or HTML
data to help me build an external request.
Raw from SoapUI for my request
POST http://192.168.0.28:10005/MainService/WindowsService HTTP/1.1
Accept-Encoding: gzip,deflate
Content-Type: text/xml;charset=UTF-8
SOAPAction: "http://Main.Service/AUserService/GetUsers"
Content-Length: 303
Host: 192.168.0.28:10005
Connection: Keep-Alive
User-Agent: Apache-HttpClient/4.1.1 (java 1.5)
XML from SoapUI
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:qtre="http://Main.Service">

<soapenv:Body>
<qtre:GetUsers>
<qtre:sSearchText></qtre:sSearchText>
</qtre:GetUsers>
</soapenv:Body>
</soapenv:Envelope>
I used the above to build the following node
request
:
var request = require('request');
let xml =
`<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:qtre="http://Main.Service">

</qtre:GetUsers>
</soapenv:Body>
</soapenv:Envelope>`
var options = {
url: 'http://192.168.0.28:10005/MainService/WindowsService?wsdl',
method: 'POST',
body: xml,
headers: {
'Content-Type':'text/xml;charset=utf-8',
'Accept-Encoding': 'gzip,deflate',
'Content-Length':xml.length,
'SOAPAction':"http://Main.Service/AUserService/GetUsers"
}
};
let callback = (error, response, body) => {
if (!error && response.statusCode == 200) {
console.log('Raw result', body);
var xml2js = require('xml2js');
var parser = new xml2js.Parser({explicitArray: false, trim: true});
parser.parseString(body, (err, result) => {
console.log('JSON result', result);
});
};
console.log('E', response.statusCode, response.statusMessage);
};
request(options, callback);
You need to add the package containing the executable pg_config.
A prior answer should have details you need: pg_config executable not found
So, why didn't anybody suggest just using options that eliminate the parts he doesn't want to process.
On modern Debian you just get your file with:
ls --format=single-column
Further more, you don't have to pay attention to what directory you are running it in if you use the full directory:
ls --format=single-column /root/dir/starting/point/to/target/dir/
This last command I am using the above and I get the following output:
bot@dev:~/downloaded/Daily# ls --format=single-column /home/bot/downloaded/Daily/*.gz
/home/bot/downloaded/Daily/Liq_DailyManifest_V3_US_20141119_IENT1.txt.gz

You can reach main page with parent command (parent is the window) after the step you can make everything...
function funcx() {
var result = confirm('bla bla bla.!');
if(result)
//parent.location.assign("http://localhost:58250/Ekocc/" + document.getElementById('hdnLink').value + "");
parent.location.assign("http://blabla.com/" + document.getElementById('hdnLink').value + "");
}
Your Fundamentals are wrong, the program won't work, so go through the basics and rewrite the program.
Some of the corrections you must make are:
1) You must make a variable of semaphore type
sem_t semvar;
2) The functions sem_wait()
, sem_post()
require the semaphore variable but you are passing the semaphore id, which makes no sense.
sem_wait(&semvar);
//your critical section code
sem_post(&semvar);
3) You are passing the semaphore to sem_wait()
and sem_post()
without initializing it. You must initialize it to 1 (in your case) before using it, or you will have a deadlock.
ret = semctl( semid, 1, SETVAL, sem);
if (ret == 1)
perror("Semaphore failed to initialize");
Study the semaphore API's from the man page and go through this example.

Due to the fact that I answered this in 2014, I have updated my answer to account for more recent versions of ansible.
Yes, you can do it at the host/inventory level (Which became possible on newer ansible versions) or global level:
inventory:
Add the following.
ansible_ssh_common_args='-o StrictHostKeyChecking=no'
host:
Add the following.
ansible_ssh_extra_args='-o StrictHostKeyChecking=no'
hosts/inventory options will work with connection type ssh
and not paramiko
. Some people may strongly argue that inventory and hosts is more secure because the scope is more limited.
global:
Ansible User Guide - Host Key Checking
You can do it either in the /etc/ansible/ansible.cfg
or ~/.ansible.cfg
file:
[defaults]
host_key_checking = False
Or you can setup and env variable (this might not work on newer ansible versions):
export ANSIBLE_HOST_KEY_CHECKING=False
You can use If function Write in the cell where you want to input the date the following formula: =IF(MODIFIED-CELLNUMBER<>"",IF(CELLNUMBER-WHERE-TO-INPUT-DATE="",NOW(),CELLNUMBER-WHERE-TO-INPUT-DATE),"")
When you pass a pointer by a non-const
reference, you are telling the compiler that you are going to modify that pointer's value. Your code does not do that, but the compiler thinks that it does, or plans to do it in the future.
To fix this error, either declare x
constant
// This tells the compiler that you are not planning to modify the pointer
// passed by reference
void test(float * const &x){
*x = 1000;
}
or make a variable to which you assign a pointer to nKByte
before calling test
:
float nKByte = 100.0;
// If "test()" decides to modify `x`, the modification will be reflected in nKBytePtr
float *nKBytePtr = &nKByte;
test(nKBytePtr);
we can simply use in.next().charAt(0); to assign + - * / operations as characters by initializing operation as a char.
import java.util.*; public class Calculator {
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
char operation;
int num1;
int num2;
System.out.println("Enter First Number");
num1 = in.nextInt();
System.out.println("Enter Operation");
operation = in.next().charAt(0);
System.out.println("Enter Second Number");
num2 = in.nextInt();
if (operation == '+')//make sure single quotes
{
System.out.println("your answer is " + (num1 + num2));
}
if (operation == '-')
{
System.out.println("your answer is " + (num1 - num2));
}
if (operation == '/')
{
System.out.println("your answer is " + (num1 / num2));
}
if (operation == '*')
{
System.out.println("your answer is " + (num1 * num2));
}
}
}
Try that
First place
global $var;
$var = 'value';
Second place
global $var;
if (isset($_POST['save_exit']))
{
echo $var;
}
Or if you want to be more explicit you can use the globals array:
$GLOBALS['var'] = 'test';
// after that
echo $GLOBALS['var'];
And here is third options which has nothing to do with PHP global that is due to the lack of clarity and information in the question. So if you have form in HTML and you want to pass "variable"/value to another PHP script you have to do the following:
HTML form
<form action="script.php" method="post">
<input type="text" value="<?php echo $var?>" name="var" />
<input type="submit" value="Send" />
</form>
PHP script ("script.php")
<?php
$var = $_POST['var'];
echo $var;
?>
You can also do,

In IE8 using .Net, setting the iframe.src

A major difference between them is that value-type variables store values, so specifying a value-type variable in a method call passes a copy of that variable's value to the method. Reference-type variables store references to objects, so specifying a reference-type variable as an argument passes the method a copy of the actual reference that refers to the object. Even though the reference itself is passed by value, the method can still use the reference it receives to interact with—and possibly modify—the original object. Similarly, when returning information from a method via a return statement, the method returns a copy of the value stored in a value-type variable or a copy of the reference stored in a reference-type variable. When a reference is returned, the calling method can use that reference to interact with the referenced object. So, in effect, objects are always passed by reference.
In c#, to pass a variable by reference so the called method can modify the variable's, C# provides keywords ref and out. Applying the ref keyword to a parameter declaration allows you to pass a variable to a method by reference—the called method will be able to modify the original variable in the caller. The ref keyword is used for variables that already have been initialized in the calling method. Normally, when a method call contains an uninitialized variable as an argument, the compiler generates an error. Preceding a parameter with keyword out creates an output parameter. This indicates to the compiler that the argument will be passed into the called method by reference and that the called method will assign a value to the original variable in the caller. If the method does not assign a value to the output parameter in every possible path of execution, the compiler generates an error. This also prevents the compiler from generating an error message for an uninitialized variable that is passed as an argument to a method. A method can return only one value to its caller via a return statement, but can return many values by specifying multiple output (ref and/or out) parameters.

In answer to your third question: your client wants to be able to cope with temporary network problems anyway, e.g. let's say the user closes their laptop between meetings which hibernates it, or the network simply goes down temporarily.
The solution is to listen to onclose
events on the web socket client and when they occur, set a client side timeout to re-open the connection, say in a second:
function setupWebSocket(){
this.ws = new WebSocket('wss://host:port/path');
this.ws.onerror = ...;
this.ws.onopen = ...;
this.ws.onmessage = ...;
this.ws.onclose = function(){
setTimeout(setupWebSocket, 1000);
};
}
I had this error message having started up a second Tomcat server on a Linux server.
$CATALINA_PID was set but the specified file does not exist. Is Tomcat running? Stop aborted.
When starting up the 2nd Tomcat I had set CATALINA_PID as asked but my mistake was to set it to a directory (I assumed Tomcat would write a default file name in there with the pid).
The fix was simply to change my CATALINA_PID to add a file name to the end of it (I chose catalina.pid from the above examples). Next I went to the directory and did a simple:
touch catalina.pid
creating an empty file of the correct name. Then when I did my shutdown.sh I got the message back saying:
PID file is empty and has been ignored.
Tomcat stopped.
I didn't have the option to kill Tomcat as the JVM was in use so I was glad I found this.
It's a mechanism to invoke an API in an asynchrounous way. The sequence is the following
So you can invoke the api and tell your user the request is "processing" or "acquired" for example, and then update the status when you receive the response from the api.

The usual WPF timer is the DispatcherTimer
, which is not a control but used in code. It basically works the same way like the WinForms timer:
System.Windows.Threading.DispatcherTimer dispatcherTimer = new System.Windows.Threading.DispatcherTimer();
dispatcherTimer.Tick += dispatcherTimer_Tick;
dispatcherTimer.Interval = new TimeSpan(0,0,1);
dispatcherTimer.Start();
private void dispatcherTimer_Tick(object sender, EventArgs e)
{
// code goes here
}

I don't think you need javascript or CSS to fix this.
According to the html 5 spec for buttons a button with no type attribute is treated the same as a button with its type set to "submit", i.e. as a button for submitting its containing form. Setting the button's type to "button" should prevent the behaviour you're seeing.
I'm not sure about browser support for this, but the same behaviour was specified in the html 4.01 spec for buttons so I expect it's pretty good.
Make sure you're calling super()
as the first thing in your constructor.
You should set this
for setAuthorState
method
class ManageAuthorPage extends Component {
state = {
author: { id: '', firstName: '', lastName: '' }
};
constructor(props) {
super(props);
this.handleAuthorChange = this.handleAuthorChange.bind(this);
}
handleAuthorChange(event) {
let {name: fieldName, value} = event.target;
this.setState({
[fieldName]: value
});
};
render() {
return (
<AuthorForm
author={this.state.author}
onChange={this.handleAuthorChange}
/>
);
}
}
Another alternative based on arrow function
:
class ManageAuthorPage extends Component {
state = {
author: { id: '', firstName: '', lastName: '' }
};
handleAuthorChange = (event) => {
const {name: fieldName, value} = event.target;
this.setState({
[fieldName]: value
});
};
render() {
return (
<AuthorForm
author={this.state.author}
onChange={this.handleAuthorChange}
/>
);
}
}
A (MySQLdb/PyMySQL-specific) difference worth noting when using a DictCursor
is that list(cursor)
will always give you a list, while cursor.fetchall()
gives you a list unless the result set is empty, in which case it gives you an empty tuple. This was the case in MySQLdb and remains the case in the newer PyMySQL, where it will not be fixed for backwards-compatibility reasons. While this isn't a violation of Python Database API Specification, it's still surprising and can easily lead to a type error caused by wrongly assuming that the result is a list, rather than just a sequence.
Given the above, I suggest always favouring list(cursor)
over cursor.fetchall()
, to avoid ever getting caught out by a mysterious type error in the edge case where your result set is empty.

If you want to have cd functionality (assuming shell=True) and still want to change the directory in terms of the Python script, this code will allow 'cd' commands to work.
import subprocess
import os
def cd(cmd):
#cmd is expected to be something like "cd [place]"
cmd = cmd + " && pwd" # add the pwd command to run after, this will get our directory after running cd
p = subprocess.Popen(cmd, shell=True, stdout=subprocess.PIPE, stderr=subprocess.PIPE, universal_newlines=True) # run our new command
out = p.stdout.read()
err = p.stderr.read()
# read our output
if out != "":
print(out)
os.chdir(out[0:len(out) - 1]) # if we did get a directory, go to there while ignoring the newline
if err != "":
print(err) # if that directory doesn't exist, bash/sh/whatever env will complain for us, so we can just use that
return
I would like to advertise the existence of the automatic introspection/reflection toolkit "IDK". It uses a meta-compiler like Qt's and adds meta information directly into object files. It is claimed to be easy to use. No external dependencies. It even allows you to automatically reflect std::string and then use it in scripts. Please look at IDK

Eager Loading: Eager Loading helps you to load all your needed entities at once. i.e. related objects (child objects) are loaded automatically with its parent object.
When to use:
Lazy Loading: In case of lazy loading, related objects (child objects) are not loaded automatically with its parent object until they are requested. By default LINQ supports lazy loading.
When to use:
NOTE: Entity Framework supports three ways to load related data - eager loading, lazy loading and explicit loading.
As you are using Excel you do not need VBA to achieve this, you can simply use the built in "Clean()" function, this removes carriage returns, line feeds etc e.g:

According to nginx documentation
there is no syntax for NOT matching a regular expression. Instead, match the target regular expression and assign an empty block, then use location / to match anything else
So you could define something like
location ~ (dir1|file2\.php) {
# empty
}
location / {
rewrite ^/(.*) http://example.com/$1 permanent;
}
Normally I would agree with Yaakov Ellis but in this special case there is another viable solution:
Use two tables:
Table: Item
Columns: ItemID, Title, Content
Indexes: ItemID
Table: Tag
Columns: ItemID, Title
Indexes: ItemId, Title
This has some major advantages:
First it makes development much simpler: in the three-table solution for insert and update of item
you have to lookup the Tag
table to see if there are already entries. Then you have to join them with new ones. This is no trivial task.
Then it makes queries simpler (and perhaps faster). There are three major database queries which you will do: Output all Tags
for one Item
, draw a Tag-Cloud and select all items for one Tag Title.
All Tags for one Item:
3-Table:
SELECT Tag.Title
FROM Tag
JOIN ItemTag ON Tag.TagID = ItemTag.TagID
WHERE ItemTag.ItemID = :id
2-Table:
SELECT Tag.Title
FROM Tag
WHERE Tag.ItemID = :id
Tag-Cloud:
3-Table:
SELECT Tag.Title, count(*)
FROM Tag
JOIN ItemTag ON Tag.TagID = ItemTag.TagID
GROUP BY Tag.Title
2-Table:
SELECT Tag.Title, count(*)
FROM Tag
GROUP BY Tag.Title
Items for one Tag:
3-Table:
SELECT Item.*
FROM Item
JOIN ItemTag ON Item.ItemID = ItemTag.ItemID
JOIN Tag ON ItemTag.TagID = Tag.TagID
WHERE Tag.Title = :title
2-Table:
SELECT Item.*
FROM Item
JOIN Tag ON Item.ItemID = Tag.ItemID
WHERE Tag.Title = :title
But there are some drawbacks, too: It could take more space in the database (which could lead to more disk operations which is slower) and it's not normalized which could lead to inconsistencies.
The size argument is not that strong because the very nature of tags is that they are normally pretty small so the size increase is not a large one. One could argue that the query for the tag title is much faster in a small table which contains each tag only once and this certainly is true. But taking in regard the savings for not having to join and the fact that you can build a good index on them could easily compensate for this. This of course depends heavily on the size of the database you are using.
The inconsistency argument is a little moot too. Tags are free text fields and there is no expected operation like 'rename all tags "foo" to "bar"'.
So tldr: I would go for the two-table solution. (In fact I'm going to. I found this article to see if there are valid arguments against it.)
The way the function rand()
works is that every time you call it, it generates a random number. In your code, you've called it once and stored it into the variable random_x
. To get your desired random numbers instead of storing it into a variable, just call the function like this:
for (int t=0;t<10;t++)
{
cout << "\nRandom X = " << rand() % 100;
}
You should use append to add to the list. But also here are few code tips:
I would use dict.setdefault
or defaultdict
to avoid having to specify the empty list in the dictionary definition.
If you use prev
to to filter out duplicated values you can simplfy the code using groupby
from itertools
Your code with the amendments looks as follows:
import itertools
def make_drug_dictionary(data):
drug_dictionary = {}
for key, row in itertools.groupby(data, lambda x: x[11]):
drug_dictionary.setdefault(key,[]).append(row[?])
return drug_dictionary
If you don't know how groupby works just check this example:
>>> list(key for key, val in itertools.groupby('aaabbccddeefaa'))
['a', 'b', 'c', 'd', 'e', 'f', 'a']
The static
modifier after import
is for retrieving/using static fields of a class. One area in which I use import static
is for retrieving constants from a class.
We can also apply import static
on static methods. Make sure to type import static
because static import
is wrong.

Well, I tried everything posted here, unfortunately nothings works in my case. So, trying different combinations I came out with this one that solved my problem.
1) Open the .classpath file at the root of your eclipse's project.
2) Insert the following entry to the file:
<classpathentry kind="con" path="org.eclipse.m2e.MAVEN2_CLASSPATH_CONTAINER">
<attributes>
<attribute name="maven.pomderived" value="true"/>
<attribute name="org.eclipse.jst.component.nondependency" value=""/>
</attributes>
</classpathentry>
Then, rebuild your project at eclipse (Project->Clean-Build).
if you use external libraries in your program and you try to pack all together in a jar file it's not that simple, because of classpath issues etc.
I'd prefer to use OneJar for this issue.

Cloning into an existing directory is only allowed if the directory is empty.
As an alternative to WMI you can get fast accurate results by tapping in to WinSpool.drv (i.e. Windows API) - you can get all the details on the interfaces, structs & constants from pinvoke.net, or I've put the code together at http://delradiesdev.blogspot.com/2012/02/accessing-printer-status-using-winspool.html
For me, I tried manage app execution aliases
and got an error that python3 is not a command so for that, I used py
instead of python3
and it worked
I don't know why this is happening but It worked for me
Replace the username and password with Integrated Security=SSPI;
So the connection string should be
<connectionStrings>
<add name="NorthwindContex"
connectionString="data source=localhost;
initial catalog=northwind;persist security info=True;
Integrated Security=SSPI;"
providerName="System.Data.SqlClient" />
</connectionStrings>
For those using Mac and you get a command not found error, what you need to do is
type
./adb install "yourapk.apk"
If you wish to use "like" as a parameter your link needs to be:
<a href="/topic.php?like=like">Like</a>
More likely though is that you want:
<a href="/topic.php?id=14&like=like">Like</a>
You need to set up your tracking (upstream) for the current branch
git branch --set-upstream master origin/master
Is already deprecated instead of that you can use --track flag
git branch --track master origin/master
I also like the doc reference that @casey notice:
-u <upstream>
Set up <branchname>'s tracking information so <upstream> is considered
<branchname>'s upstream branch. If no <branchname> is specified,
then it defaults to the current branch.
This should do it

Actually, the standard shell is Bourne shell (sh
). /bin/sh
on Linux is actually bash
, but if you're aiming for cross-platform scripts, you're better off sticking to features of the original Bourne shell or writing it in something like perl
.
Big difference between an image and an iframe is the fact that an image keeps its aspect-ratio. You could combine an image and an iframe with will result in a responsive iframe. Hope this answerers your question.
Check this link for example : http://jsfiddle.net/Masau/7WRHM/
HTML:
<div class="wrapper">
<div class="h_iframe">
<!-- a transparent image is preferable -->
<img class="ratio" src="http://placehold.it/16x9"/>
<iframe src="http://www.youtube.com/embed/WsFWhL4Y84Y" frameborder="0" allowfullscreen></iframe>
</div>
<p>Please scale the "result" window to notice the effect.</p>
</div>
CSS:
html,body {height:100%;}
.wrapper {width:80%;height:100%;margin:0 auto;background:#CCC}
.h_iframe {position:relative;}
.h_iframe .ratio {display:block;width:100%;height:auto;}
.h_iframe iframe {position:absolute;top:0;left:0;width:100%; height:100%;}
note: This only works with a fixed aspect-ratio.
You can iterate through the array and set a "flag" value if strpos
returns false
.
$flag = false;
foreach ($find_letters as $letter)
{
if (strpos($string, $letter) === false)
{
$flag = true;
}
}
Then check the value of $flag
.
public class FindTextInLine {
String match = "123woods";
String text = "I will come and meet you at the 123woods";
public void findText () {
if (text.contains(match)) {
System.out.println("Keyword matched the string" );
}
}
}
No. While you can set a base font size on body
using the font-size
property, anything after that that specifies a smaller size will override the base rule for that element. In order to do what you are looking to do you will need to use Javascript.
You could iterate through the elements on the page and change the smaller fonts using something like this:
$("*").each( function () {
var $this = $(this);
if (parseInt($this.css("fontSize")) < 12) {
$this.css({ "font-size": "12px" });
}
});
Here is a Fiddle where you can see it done: http://jsfiddle.net/mifi79/LfdL8/2/
(string)((int)"00000234892839")
I did a little research and was able to write this code:
strbody = "<BODY style=font-size:11pt;font-family:Calibri>Good Morning;<p>We have completed our main aliasing process for today. All assigned firms are complete. Please feel free to respond with any questions.<p>Thank you.</BODY>"
apparently by setting the "font-size=11pt"
instead of setting the font size <font size=5>
,
It allows you to select a specific font size like you normally would in a text editor, as opposed to selecting a value from 1-7 like my code was originally.
This link from simpLE MAn gave me some good info.
Without telling us what language this dll/assembly is from, we can only guess.
So how about .NET Reflector
I've used this solution to get what you need.
Let'say that in my .aspx code there's a select list runat="server":
<select id="testSelect" runat="server" ClientIDMode="Static" required>
<option value="1">One</option>
<option value="2">Two</option>
</select>
In my C# code I used the code below to retrieve the text and also value of the options:
testSelect.SelectedIndex == 0 ? "uninformed" :
testSelect.Items[testSelect.SelectedIndex].Text);
In this case I check if the user selected any of the options. If there's nothing selected I show the text as "uninformed".
Well, first I will tell the errors in two code snippets.
First code snippet
public class Program
{
public constructor() // Error - Return type for the method is missing
{
function();
}
private void function()
{
//do stuff
}
public static void main(String[] args)
{
constructor a = new constructor(); // Error - constructor cannot be resolved to a type
}
}
As you can see the code above, constructor name is not same as class name. In the main()
method you are creating a object from a method which has no return type.
Second code snippet
public class Program
{
public static void main(String[] args)
{
function(); // Error - Cannot make a static reference to the non-static method function() from the type Program
}
private void function()
{
//do stuff
}
}
Now in this code snippet you're trying to create a static reference to the non-static method function() from the type Program
, which is not possible.
So the possible solution is this,
First code snippet
public class Program
{
public Program()
{
function();
}
private void function()
{
//do stuff
}
public static void main(String[] args)
{
Program a = new Program();
a.function();
}
}
Second code snippet
public class Program
{
public static void main(String[] args)
{
Program a = new Program();
a.function();
}
private void function()
{
//do stuff
}
}
Finally the difference between the code snippets is that, in first code snippet class name is not same as the class name
While in the second code snippet there is no constructor defined.
Meanwhile to understand the purpose of constructor refer resources below,
https://docs.oracle.com/javase/7/docs/api/java/lang/reflect/Constructor.html
In recent Git (I'm using v2.15.1), the following will merge upstream submodule changes into the submodules recursively:
git submodule update --recursive --remote --merge
You may add --init
to initialize any uninitialized submodules and use --rebase
if you want to rebase instead of merge.
You need to commit the changes afterwards:
git add . && git commit -m 'Update submodules to latest revisions'
You can do
$('.myCheckbox').attr('checked',true) //Standards compliant
or
$("form #mycheckbox").attr('checked', true)
If you have custom code in the onclick event for the checkbox that you want to fire, use this one instead:
$("#mycheckbox").click();
You can uncheck by removing the attribute entirely:
$('.myCheckbox').removeAttr('checked')
You can check all checkboxes like this:
$(".myCheckbox").each(function(){
$("#mycheckbox").click()
});
I know this is an old question, but I wanted to add that, as of JodaTime 2.0, you can do this with a one-liner:
DateTime date = DateTime.parse("04/02/2011 20:27:05",
DateTimeFormat.forPattern("dd/MM/yyyy HH:mm:ss"));
One possibility is the next:
console.log([1, 2, 3].map(e => Math.random().toString(36).slice(2)).join('').split('').map(e => Math.random() > 0.5 ? e.toUpperCase() : e).join(''));
HostListener should be the proper way to bind event into your component:
@Component({
selector: 'your-element'
})
export class YourElement {
@HostListener('click', ['$event']) onClick(event) {
console.log('component is clicked');
console.log(event);
}
}
Try -Xdiag.
Steve C's answer covers the possible cases nicely, but sometimes to determine whether the class could not be found or loaded might not be that easy. Use java -Xdiag
(since JDK 7). This prints out a nice stacktrace which provides a hint to what the message Could not find or load main class
message means.
For instance, it can point you to other classes used by the main class that could not be found and prevented the main class to be loaded.
Simple way to compare time is :
$time = date('H:i:s',strtotime("11 PM"));
if($time < date('H:i:s')){
// your code
}
A more recent way to do this is to use the .to_numpy() function.
If I have a dataframe with a column 'price', I can convert it as follows:
priceArray = df['price'].to_numpy()
You can also pass the data type, such as float or object, as an argument of the function
I know nothing about Jenkins, but it looks like you are trying to access environment variables using some form of unix syntax - that won't work.
If the name of the variable is WORKSPACE, then the value is expanded in Windows batch using
%WORKSPACE%
. That form of expansion is performed at parse time. For example, this will print to screen the value of WORKSPACE
echo %WORKSPACE%
If you need the value at execution time, then you need to use delayed expansion !WORKSPACE!
. Delayed expansion is not normally enabled by default. Use SETLOCAL EnableDelayedExpansion
to enable it. Delayed expansion is often needed because blocks of code within parentheses and/or multiple commands concatenated by &
, &&
, or ||
are parsed all at once, so a value assigned within the block cannot be read later within the same block unless you use delayed expansion.
setlocal enableDelayedExpansion
set WORKSPACE=BEFORE
(
set WORKSPACE=AFTER
echo Normal Expansion = %WORKSPACE%
echo Delayed Expansion = !WORKSPACE!
)
The output of the above is
Normal Expansion = BEFORE
Delayed Expansion = AFTER
Use HELP SET
or SET /?
from the command line to get more information about Windows environment variables and the various expansion options. For example, it explains how to do search/replace and substring operations.

I have struggled with a similar issue for one day... My Scenario:
I have a SpringBoot application and I use applicationContext.xml in scr/main/resources
to configure all my Spring Beans.
For testing(integration testing) I use another applicationContext.xml in test/resources
and things worked as I have expected: Spring/SpringBoot would override applicationContext.xml from scr/main/resources
and would use the one for Testing which contained the beans configured for testing.
However, just for one UnitTest I wanted yet another customization for the applicationContext.xml used in Testing, just for this Test I wanted to used some mockito beans, so I could mock
and verify
, and here started my one day head-ache!
The problem is that Spring/SpringBoot doesn't not override the applicationContext.xml from scr/main/resources
ONLY IF the file from test/resources
HAS the SAME NAME.
I tried for hours to use something like:
@RunWith(SpringJUnit4ClassRunner.class)
@OverrideAutoConfiguration(enabled=true)
@ContextConfiguration({"classpath:applicationContext-test.xml"})
it did not work, Spring was first loading the beans from applicationContext.xml in scr/main/resources
My solution based on the answers here by @myroch and @Stuart:
Define the main configuration of the application:
@Configuration
@ImportResource({"classpath:applicationContext.xml"})
public class MainAppConfig {
}
this is used in the application
@SpringBootApplication
@Import(MainAppConfig.class)
public class SuppressionMain implements CommandLineRunner
Define a TestConfiguration for the Test where you want to exclude the main configuration
@ComponentScan( basePackages = "com.mypackage", excludeFilters = { @ComponentScan.Filter(type = ASSIGNABLE_TYPE, value = {MainAppConfig.class}) }) @EnableAutoConfiguration public class TestConfig { }
By doing this, for this Test, Spring will not load applicationContext.xml and will load only the custom configuration specific for this Test.
Another approach if you wanted to swap out a specific character for another character:
def swap(input_string):
if len(input_string) == 0:
return input_string
if input_string[0] == "x":
return "y" + swap(input_string[1:])
else:
return input_string[0] + swap(input_string[1:])
There's an open issue for this in Google's IssueTracker.
The potential solutions given in the issue (as of the date of this post) are:
The Microsoft Program Maintenance Utility (NMAKE.EXE) is a tool that builds projects based on commands contained in a description file.
The call
e.extractAll("th")
for a regular method extractAll()
is indeed equivalent to
Extractor.extractAll(e, "th")
These two calls are treated the same in all regards, including the error messages you get.
If you don't need to pass the instance to a method, you can use a staticmethod
:
@staticmethod
def extractAll(tag):
...
which can be called as e.extractAll("th")
. But I wonder why this is a method on a class at all if you don't need to access any instance.
Copied from the formal specification: ECMAScript 5.1 section 11.9.5
11.9.4 The Strict Equals Operator ( === )
The production EqualityExpression : EqualityExpression === RelationalExpression is evaluated as follows:
- Let lref be the result of evaluating EqualityExpression.
- Let lval be GetValue(lref).
- Let rref be the result of evaluating RelationalExpression.
- Let rval be GetValue(rref).
- Return the result of performing the strict equality comparison rval === lval. (See 11.9.6)
11.9.5 The Strict Does-not-equal Operator ( !== )
The production EqualityExpression : EqualityExpression !== RelationalExpression is evaluated as follows:
- Let lref be the result of evaluating EqualityExpression.
- Let lval be GetValue(lref).
- Let rref be the result of evaluating RelationalExpression.
- Let rval be GetValue(rref). Let r be the result of performing strict equality comparison rval === lval. (See 11.9.6)
- If r is true, return false. Otherwise, return true.
11.9.6 The Strict Equality Comparison Algorithm
The comparison x === y, where x and y are values, produces true or false. Such a comparison is performed as follows:
- If Type(x) is different from Type(y), return false.
- Type(x) is Undefined, return true.
- Type(x) is Null, return true.
- Type(x) is Number, then
- If x is NaN, return false.
- If y is NaN, return false.
- If x is the same Number value as y, return true.
- If x is +0 and y is -0, return true.
- If x is -0 and y is +0, return true.
- Return false.
- If Type(x) is String, then return true if x and y are exactly the same sequence of characters (same length and same characters in corresponding positions); otherwise, return false.
- If Type(x) is Boolean, return true if x and y are both true or both false; otherwise, return false.
- Return true if x and y refer to the same object. Otherwise, return false.
For Laravel
Step 1. Open your terminal
step 2. cd
into your laravel directory
step 3. Type the command which composer
, in your laravel directory and note the directory in which composer resides.
step 4. run the command php -d memory_limit=-1 /opt/cpanel/bin/composer update
(you can also run the code if it works for you)
(change /opt/cpanel/bin/composer
to the directory path returned in step 3 )

You can create an iterator in Python 3.x or a list in Python 2.x by using:
filter(r.match, list)
To convert the Python 3.x iterator to a list, simply cast it; list(filter(..))

Oracle's JVM implementation for Java 8 got rid of the PermGen model and replaced it with Metaspace.
This is an array of the command line switches pass to the program. E.g. if you start the program with the command "myapp.exe -c -d
" then string[] args[]
will contain the strings "-c" and "-d".

It's probably like that because of efficiency and because if you have multiple programs writing to a single TTY, this way you don't get characters on a line interlaced. So if program A and B are outputting, you'll usually get:
program A output
program B output
program B output
program A output
program B output
This stinks, but it's better than
proprogrgraam m AB ououtputputt
prproogrgram amB A ououtputtput
program B output
Note that it isn't even guaranteed to flush on a newline, so you should flush explicitly if flushing matters to you.
The following should work:
ABC: *\([a-zA-Z]+\) *(.+)
Explanation:
ABC: # match literal characters 'ABC:'
* # zero or more spaces
\([a-zA-Z]+\) # one or more letters inside of parentheses
* # zero or more spaces
(.+) # capture one or more of any character (except newlines)
To get your desired grouping based on the comments below, you can use the following:
(ABC:) *(\([a-zA-Z]+\).+)
You need to set the thumbnail class to position relative then the post-content to absolute.
Check this fiddle
.post-content {
top:0;
left:0;
position: absolute;
}
.thumbnail{
position:relative;
}
Giving it top and left 0 will make it appear in the top left corner.
All the others have already mentioned the use of the scripting.runtime version of the Dictionary class. If you are unable to use this DLL you can also use this version, simply add it to your code.
https://github.com/VBA-tools/VBA-Dictionary/blob/master/Dictionary.cls
It is identical to Microsoft's version.
With Java 8 there is this API method to accomplish your requirement.
map.putIfAbsent(key, value)
If the specified key is not already associated with a value (or is mapped to null) associates it with the given value and returns null, else returns the current value.
GNU Parallel can presumably be used to improve many of the above answers by spreading the workload across multiple cores.
In the example below we send chunks of 500 numbers (--max-lines=500
) to bc
processes which are executed in parallel 4 at a time (-j 4
). The results are then aggregated by a final bc
.
time parallel --max-lines=500 -j 4 --pipe "paste -sd+ - | bc" < random_numbers | paste -sd+ - | bc
The optimal choice of work size and number of parallel processes depends on the machine and problem. Note that this solution only really shines when there's a large number of parallel processes with substantial work each.
You can use VLOOKUP
.
Assuming those are in columns A and B in Sheet1 and Sheet2 each, 22350 is in cell A2 of Sheet1, you can use:
=VLOOKUP(A2, Sheet2!A:B, 2, 0)
This will return you #N/A
if there are no matches. Drag/Fill/Copy&Paste the formula to the bottom of your table and that should do it.
If you want to set only one specific class, you might write a TypeScript function returning a boolean to determine when the class should be appended.
TypeScript
function hideThumbnail():boolean{
if (/* Your criteria here */)
return true;
}
CSS:
.request-card-hidden {
display: none;
}
HTML:
<ion-note [class.request-card-hidden]="hideThumbnail()"></ion-note>
I've managed to achieve it with minimal effort (just as simple as with ASP.NET Core).
For that I use OWIN Startup.cs
file and Microsoft.Owin.Security.Jwt
library.
In order for the app to hit Startup.cs
we need to amend Web.config
:
<configuration>
<appSettings>
<add key="owin:AutomaticAppStartup" value="true" />
...
Here's how Startup.cs
should look:
using MyApp.Helpers;
using Microsoft.IdentityModel.Tokens;
using Microsoft.Owin;
using Microsoft.Owin.Security;
using Microsoft.Owin.Security.Jwt;
using Owin;
[assembly: OwinStartup(typeof(MyApp.App_Start.Startup))]
namespace MyApp.App_Start
{
public class Startup
{
public void Configuration(IAppBuilder app)
{
app.UseJwtBearerAuthentication(
new JwtBearerAuthenticationOptions
{
AuthenticationMode = AuthenticationMode.Active,
TokenValidationParameters = new TokenValidationParameters()
{
ValidAudience = ConfigHelper.GetAudience(),
ValidIssuer = ConfigHelper.GetIssuer(),
IssuerSigningKey = ConfigHelper.GetSymmetricSecurityKey(),
ValidateLifetime = true,
ValidateIssuerSigningKey = true
}
});
}
}
}
Many of you guys use ASP.NET Core nowadays, so as you can see it doesn't differ a lot from what we have there.
It really got me perplexed first, I was trying to implement custom providers, etc. But I didn't expect it to be so simple. OWIN
just rocks!
Just one thing to mention - after I enabled OWIN Startup NSWag
library stopped working for me (e.g. some of you might want to auto-generate typescript HTTP proxies for Angular app).
The solution was also very simple - I replaced NSWag
with Swashbuckle
and didn't have any further issues.
Ok, now sharing ConfigHelper
code:
public class ConfigHelper
{
public static string GetIssuer()
{
string result = System.Configuration.ConfigurationManager.AppSettings["Issuer"];
return result;
}
public static string GetAudience()
{
string result = System.Configuration.ConfigurationManager.AppSettings["Audience"];
return result;
}
public static SigningCredentials GetSigningCredentials()
{
var result = new SigningCredentials(GetSymmetricSecurityKey(), SecurityAlgorithms.HmacSha256);
return result;
}
public static string GetSecurityKey()
{
string result = System.Configuration.ConfigurationManager.AppSettings["SecurityKey"];
return result;
}
public static byte[] GetSymmetricSecurityKeyAsBytes()
{
var issuerSigningKey = GetSecurityKey();
byte[] data = Encoding.UTF8.GetBytes(issuerSigningKey);
return data;
}
public static SymmetricSecurityKey GetSymmetricSecurityKey()
{
byte[] data = GetSymmetricSecurityKeyAsBytes();
var result = new SymmetricSecurityKey(data);
return result;
}
public static string GetCorsOrigins()
{
string result = System.Configuration.ConfigurationManager.AppSettings["CorsOrigins"];
return result;
}
}
Another important aspect - I sent JWT Token via Authorization header, so typescript code looks for me as follows:
(the code below is generated by NSWag)
@Injectable()
export class TeamsServiceProxy {
private http: HttpClient;
private baseUrl: string;
protected jsonParseReviver: ((key: string, value: any) => any) | undefined = undefined;
constructor(@Inject(HttpClient) http: HttpClient, @Optional() @Inject(API_BASE_URL) baseUrl?: string) {
this.http = http;
this.baseUrl = baseUrl ? baseUrl : "https://localhost:44384";
}
add(input: TeamDto | null): Observable<boolean> {
let url_ = this.baseUrl + "/api/Teams/Add";
url_ = url_.replace(/[?&]$/, "");
const content_ = JSON.stringify(input);
let options_ : any = {
body: content_,
observe: "response",
responseType: "blob",
headers: new HttpHeaders({
"Content-Type": "application/json",
"Accept": "application/json",
"Authorization": "Bearer " + localStorage.getItem('token')
})
};
See headers part - "Authorization": "Bearer " + localStorage.getItem('token')
Try this example and you will understand also what is the difference between Associative Array and Object in JavaScript.
Associative Array
var a = new Array(1,2,3);
a['key'] = 'experiment';
Array.isArray(a);
returns true
Keep in mind that a.length
will be undefined, because length
is treated as a key, you should use Object.keys(a).length
to get the length of an Associative Array.
Object
var a = {1:1, 2:2, 3:3,'key':'experiment'};
Array.isArray(a)
returns false
JSON returns an Object ... could return an Associative Array ... but it is not like that

I've used WingIDE and have been very happy. Intellisense is pretty good, some other things are a bit wacky but overall it's a very productive tool
the third way is to base64 encode the image and place it in a data:

app.use
is the "lower level" method from Connect, the middleware framework that Express depends on.
Here's my guideline:
app.get
if you want to expose a GET method.app.use
if you want to add some middleware (a handler for the HTTP request before it arrives to the routes you've set up in Express), or if you'd like to make your routes modular (for example, expose a set of routes from an npm module that other web applications could use).You could actually use xlsread
to accomplish this. After first placing your sample data above in a file 'input_file.csv'
, here is an example for how you can get the numeric values, text values, and the raw data in the file from the three outputs from xlsread
:
>> [numData,textData,rawData] = xlsread('input_file.csv')
numData = % An array of the numeric values from the file
51.9358 4.1833
51.9354 4.1841
51.9352 4.1846
51.9343 4.1864
51.9343 4.1864
51.9341 4.1869
textData = % A cell array of strings for the text values from the file
'ABC'
'ABC'
'ABC'
'ABC'
'ABC'
'ABC'
rawData = % All the data from the file (numeric and text) in a cell array
'ABC' [51.9358] [4.1833]
'ABC' [51.9354] [4.1841]
'ABC' [51.9352] [4.1846]
'ABC' [51.9343] [4.1864]
'ABC' [51.9343] [4.1864]
'ABC' [51.9341] [4.1869]
You can then perform whatever processing you need to on the numeric data, then resave a subset of the rows of data to a new file using xlswrite
. Here's an example:
index = sqrt(sum(numData.^2,2)) >= 50; % Find the rows where the point is
% at a distance of 50 or greater
% from the origin
xlswrite('output_file.csv',rawData(index,:)); % Write those rows to a new file
In my case, I forgot to add the ()
I was calling the method like this
obj = className.myMethod
But it should be is like this
obj = className.myMethod()
I didn't know you could do that with cp.
You can do it with mkdir ..
mkdir -p /var/path/to/your/dir
EDIT See lhunath's answer for incorporating cp.
If you don't mind using CMake, there is also tensorflow_cc project that builds and installs TF C++ API for you, along with convenient CMake targets you can link against. The project README contains an example and Dockerfiles you can easily follow.
If you don care about the range, the following expression will be useful to validate from 1.1.1.1 to 999.999.999.999

Though is answered in another stack overflow question Bind a function to Twitter Bootstrap Modal Close but for visual feel here is more detailed answer.
Escaping the double quotes with backslashes is the only way to do this in Java.
Some IDEs around such as IntelliJ IDEA do this escaping automatically when pasting such a String into a String literal (i.e. between the double quotes surrounding a java String literal)
One other option would be to put the String into some kind of text file that you would then read at runtime
You should be aware that you should avoid file I/O from within Linux kernel when possible. The main idea is to go "one level deeper" and call VFS level functions instead of the syscall handler directly:
Includes:
#include <linux/fs.h>
#include <asm/segment.h>
#include <asm/uaccess.h>
#include <linux/buffer_head.h>
Opening a file (similar to open):
struct file *file_open(const char *path, int flags, int rights)
{
struct file *filp = NULL;
mm_segment_t oldfs;
int err = 0;
oldfs = get_fs();
set_fs(get_ds());
filp = filp_open(path, flags, rights);
set_fs(oldfs);
if (IS_ERR(filp)) {
err = PTR_ERR(filp);
return NULL;
}
return filp;
}
Close a file (similar to close):
void file_close(struct file *file)
{
filp_close(file, NULL);
}
Reading data from a file (similar to pread):
int file_read(struct file *file, unsigned long long offset, unsigned char *data, unsigned int size)
{
mm_segment_t oldfs;
int ret;
oldfs = get_fs();
set_fs(get_ds());
ret = vfs_read(file, data, size, &offset);
set_fs(oldfs);
return ret;
}
Writing data to a file (similar to pwrite):
int file_write(struct file *file, unsigned long long offset, unsigned char *data, unsigned int size)
{
mm_segment_t oldfs;
int ret;
oldfs = get_fs();
set_fs(get_ds());
ret = vfs_write(file, data, size, &offset);
set_fs(oldfs);
return ret;
}
Syncing changes a file (similar to fsync):
int file_sync(struct file *file)
{
vfs_fsync(file, 0);
return 0;
}
[Edit] Originally, I proposed using file_fsync, which is gone in newer kernel versions. Thanks to the poor guy suggesting the change, but whose change was rejected. The edit was rejected before I could review it.
i do it with os.system temp file:
import tempfile,os
def readcmd(cmd):
ftmp = tempfile.NamedTemporaryFile(suffix='.out', prefix='tmp', delete=False)
fpath = ftmp.name
if os.name=="nt":
fpath = fpath.replace("/","\\") # forwin
ftmp.close()
os.system(cmd + " > " + fpath)
data = ""
with open(fpath, 'r') as file:
data = file.read()
file.close()
os.remove(fpath)
return data
My pseudocode example will be as follows:
JSONArray jsonArray = "[{id:\"1\", name:\"sql\"},{id:\"2\",name:\"android\"},{id:\"3\",name:\"mvc\"}]";
JSON newJson = new JSON();
for (each json in jsonArray) {
String id = json.get("id");
String name = json.get("name");
newJson.put(id, name);
}
return newJson;
On some mobiles like mine (MIUI Redmi 3) you can just add specific Application on list where application doesnt stop when you terminate applactions in Task Manager (It will stop but it will start again)
Just go to Settings>PermissionsAutostart
Case #1
Cases #2-4
These should be equivalent; HttpResponseException encapsulates an HttpResponseMessage, which is what gets returned back as the HTTP response.
e.g., case #2 could be rewritten as
public HttpResponseMessage Get(string id)
{
HttpResponseMessage response;
var customer = _customerService.GetById(id);
if (customer == null)
{
response = new HttpResponseMessage(HttpStatusCode.NotFound);
}
else
{
response = Request.CreateResponse(HttpStatusCode.OK, customer);
response.Content.Headers.Expires = new DateTimeOffset(DateTime.Now.AddSeconds(300));
}
return response;
}
... but if your controller logic is more complicated, throwing an exception might simplify the code flow.
HttpError gives you a consistent format for the response body and can be serialized to JSON/XML/etc, but it's not required. e.g., you may not want to include an entity-body in the response, or you might want some other format.
For anyone who wants to batch convert anything with ffmpeg but would like to have a convenient Windows interface, I developed this front-end:
https://sourceforge.net/projects/ffmpeg-batch
It adds to ffmpeg a window fashion interface, progress bars and time remaining info, features I always missed when using ffmpeg.
Something like this should do it:
.column-left{ float: left; width: 33.333%; }
.column-right{ float: right; width: 33.333%; }
.column-center{ display: inline-block; width: 33.333%; }
EDIT
To do this with a larger number of columns you could build a very simple grid system. For example, something like this should work for a five column layout:
.column {_x000D_
float: left;_x000D_
position: relative;_x000D_
width: 20%;_x000D_
_x000D_
/*for demo purposes only */_x000D_
background: #f2f2f2;_x000D_
border: 1px solid #e6e6e6;_x000D_
box-sizing: border-box;_x000D_
}_x000D_
_x000D_
.column-offset-1 {_x000D_
left: 20%;_x000D_
}_x000D_
.column-offset-2 {_x000D_
left: 40%;_x000D_
}_x000D_
.column-offset-3 {_x000D_
left: 60%;_x000D_
}_x000D_
.column-offset-4 {_x000D_
left: 80%;_x000D_
}_x000D_
_x000D_
.column-inset-1 {_x000D_
left: -20%;_x000D_
}_x000D_
.column-inset-2 {_x000D_
left: -40%;_x000D_
}_x000D_
.column-inset-3 {_x000D_
left: -60%;_x000D_
}_x000D_
.column-inset-4 {_x000D_
left: -80%;_x000D_
}
_x000D_
<div class="container">_x000D_
<div class="column column-one column-offset-2">Column one</div>_x000D_
<div class="column column-two column-inset-1">Column two</div>_x000D_
<div class="column column-three column-offset-1">Column three</div>_x000D_
<div class="column column-four column-inset-2">Column four</div>_x000D_
<div class="column column-five">Column five</div>_x000D_
</div>
_x000D_
Or, if you are lucky enough to be able to support only modern browsers, you can use flexible boxes:
.container {_x000D_
display: flex;_x000D_
}_x000D_
_x000D_
.column {_x000D_
flex: 1;_x000D_
_x000D_
/*for demo purposes only */_x000D_
background: #f2f2f2;_x000D_
border: 1px solid #e6e6e6;_x000D_
box-sizing: border-box;_x000D_
}_x000D_
_x000D_
.column-one {_x000D_
order: 3;_x000D_
}_x000D_
.column-two {_x000D_
order: 1;_x000D_
}_x000D_
.column-three {_x000D_
order: 4;_x000D_
}_x000D_
.column-four {_x000D_

.column-five {_x000D_

You can OpenGL without a wrapper and use it natively in C#. Just as Jeff Mc said, you would have to import all the functions you need with DllImport.
What he left out is having to create context before you can use any of the OpenGL functions. It's not hard, but there are few other not-so-intuitive DllImports that need to be done.
I have created an example C# project in VS2012 with almost the bare minimum necessary to get OpenGL running on Windows box. It only paints the window blue, but it should be enough to get you started. The example can be found at http://www.glinos-labs.org/?q=programming-opengl-csharp. Look for the No Wrapper example at the bottom.
Use XmlDocument.Load()
method to load XML from your file. Then use XmlDocument.InnerXml
property to get XML string.
XmlDocument doc = new XmlDocument();
doc.Load("path to your file");
string xmlcontents = doc.InnerXml;
Try this:
var charArray = "this is a test".ToCharArray().Select(c=>c.ToString());
You've gotten some answers, and most of them are correct, but miss what (I think) is probably the point here.
My guess is that you have a makefile you're trying to use to create an executable. In case you're not familiar with them, makefiles list dependencies between files. For a really simple case, it might have something like:
myprogram.exe: myprogram.o
$(CC) -o myprogram.exe myprogram.o
myprogram.o: myprogram.cpp
$(CC) -c myprogram.cpp
The first line says that myprogram.exe
depends on myprogram.o
. The second line tells how to create myprogram.exe
from myprogram.o
. The third and fourth lines say myprogram.o
depends on myprogram.cpp
, and how to create myprogram.o
from myprogram.cpp` respectively.
My guess is that in your case, you have a makefile like the one above that was created for gcc. The problem you're running into is that you're using it with MS VC instead of gcc. As it happens, MS VC uses ".obj" as the extension for its object files instead of ".o".
That means when make (or its equivalent built into the IDE in your case) tries to build the program, it looks at those lines to try to figure out how to build myprogram.exe
. To do that, it sees that it needs to build myprogram.o
, so it looks for the rule that tells it how to build myprogram.o
. That says it should compile the .cpp file, so it does that.
Then things break down -- the VC++ compiler produces myprogram.obj
instead of myprogram.o
as the object file, so when it tries to go to the next step to produce myprogram.exe
from myprogram.o
, it finds that its attempt at creating myprogram.o
simply failed. It did what the rule said to do, but that didn't produce myprogram.o
as promised. It doesn't know what to do, so it quits and give you an error message.
The cure for that specific problem is probably pretty simple: edit the make file so all the object files have an extension of .obj
instead of .o
. There's room for a lot of question whether that will fix everything though -- that may be all you need, or it may simply lead to other (probably more difficult) problems.
Your data may not be what you expect -- it seems you're expecting, but not getting, floats.
A simple solution to figuring out where this occurs would be to add a try/except to the for-loop:
for i in range(0,N):
w=f[i].split()
l1=w[1:8]
l2=w[8:15]
try:
list1=[float(x) for x in l1]
list2=[float(x) for x in l2]
except ValueError, e:
# report the error in some way that is helpful -- maybe print out i
result=stats.ttest_ind(list1,list2)
print result[1]
JavaScript code is usually called from the onclick
event of a link. For example, you could instead do:
In Head Section of HTML Document
<script type='text/javascript'>
function myFunction(){
//...script code
}
</script>
In Body of HTML Document
<a href="#" id="mylink" onclick="myFunction(); return false">Call JavaScript </a>
Alternatively, you can also attach your function to the link using the links' ID, and HTML DOM or a framework like JQuery.
For example:
In Head Section of HTML Document
<script type='text/javascript'>
document.getElementById("mylink").onclick = function myFunction(){ ...script code};
</script>
In Body of HTML Document
<a href="#" id="mylink">Call JavaScript </a>
The first answer you gave uses what is known as ANSI join syntax, the other is valid and will work in any relational database.
I agree with grom that you should use ANSI join syntax. As they said, the main reason is for clarity. Rather than having a where clause with lots of predicates, some of which join tables and others restricting the rows returned with the ANSI join syntax you are making it blindingly clear which conditions are being used to join your tables and which are being used to restrict the results.
I'm afraid you can't combine these functions, ie. you gotta do something like this:-
myData.unique().sort();
Alternatively you can implement a kind of sortedset (as available in other languages) - which carries both the notion of sorting and removing duplicates, as you require.
Hope this helps.

Here is a short and fast in-memory solution that I came up with utilizing the Table Valued Constructors introduced in SQL Server 2008:
It will return 1,000,000 rows, however you can either add/remove CROSS JOINs, or use TOP clause to modify this.
;WITH v AS (SELECT * FROM (VALUES(0),(0),(0),(0),(0),(0),(0),(0),(0),(0)) v(z))
SELECT N FROM (SELECT ROW_NUMBER() OVER (ORDER BY v1.z)-1 N FROM v v1
CROSS JOIN v v2 CROSS JOIN v v3 CROSS JOIN v v4 CROSS JOIN v v5 CROSS JOIN v v6) Nums
Note that this could be quickly calculated on the fly, or (even better) stored in a permanent table (just add an INTO
clause after the SELECT N
segment) with a primary key on the N
field for improved efficiency.
You want strip()
:
myphrases = [" Hello ", " Hello", "Hello ", "Bob has a cat"]
for phrase in myphrases:
print(phrase.strip())
To simply remove the title bar (which means the bar contains your app name) from an activity, I simply add below line to that activity in the manifests\AndroidManifest.xml
:
android:theme="@style/AppTheme.NoActionBar"
It should now look like below
<activity
android:name=".MyActivity"
android:theme="@style/AppTheme.NoActionBar"></activity>
Hope it'll be useful.
This is an extension to Pache's answer using Guava's ListenableFuture
.
In particular, Futures.transform()
returns ListenableFuture
so can be used to chain async calls. Futures.addCallback()
returns void
, so cannot be used for chaining, but is good for handling success/failure on an async completion.
// ListenableFuture1: Open Database
ListenableFuture<Database> database = service.submit(() -> openDatabase());
// ListenableFuture2: Query Database for Cursor rows
ListenableFuture<Cursor> cursor =
Futures.transform(database, database -> database.query(table, ...));
// ListenableFuture3: Convert Cursor rows to List<Foo>
ListenableFuture<List<Foo>> fooList =
Futures.transform(cursor, cursor -> cursorToFooList(cursor));
// Final Callback: Handle the success/errors when final future completes
Futures.addCallback(fooList, new FutureCallback<List<Foo>>() {
public void onSuccess(List<Foo> foos) {
doSomethingWith(foos);
}
public void onFailure(Throwable thrown) {
log.error(thrown);
}
});
NOTE: In addition to chaining async tasks, Futures.transform()
also allows you to schedule each task on a separate executor (Not shown in this example).
If example
is not final
then a simple reassignment would work:
example = new String[example.length];
This assumes you need the array to remain the same size. If that's not necessary then create an empty array:
example = new String[0];
If it is final
then you could null
out all the elements:
Arrays.fill( example, null );
ArrayList
or similar collectionThe console.log
should be wrapped in a function , the "default" function for every class is its constructor
so it should be declared there.
import { Component } from '@angular/core';
console.log("Hello1");
@Component({
selector: 'hello-console',
})
export class App {
s: string = "Hello2";
constructor(){
console.log(s);
}
}
The "pre Windows 2000" name i.e. DOMAIN\SomeBody
, the Somebody
portion is known as sAMAccountName.
So try:
using(DirectoryEntry de = new DirectoryEntry("LDAP://MyDomainController"))
{
using(DirectorySearcher adSearch = new DirectorySearcher(de))
{
adSearch.Filter = "(sAMAccountName=someuser)";
SearchResult adSearchResult = adSearch.FindOne();
}
}
[email protected] is the UserPrincipalName, but it isn't a required field.
Comparator
provides a way for you to provide custom comparison logic for types that you have no control over.
Comparable
allows you to specify how objects that you are implementing get compared.
Obviously, if you don't have control over a class (or you want to provide multiple ways to compare objects that you do have control over) then use Comparator
.
Otherwise you can use Comparable
.
Looking at your other question I assume you are trying to run a php or asp file or something on your webserver and this is your first attempt in webdesign.
Once you have installed php correctly (which you probably did when you got XAMPP) just place whatever file you want under your localhost (/www/var/html perhaps?) and it should run. You can check this of course at localhost/file.php in your browser.
The correct way of building client/server Microsoft Access applications where the data is stored in a RDBMS is to use the Linked Table method. This ensures Data Isolation and Concurrency is maintained between the Microsoft Access client application and the RDBMS data with no additional and unnecessary programming logic and code which makes maintenance more difficult, and adds to development time.

n = data.loc[row,'json_column']
to:
n = data.iloc[[row]]['json_column']
here's the rest of it, converting to a dictionary is helpful for working with json data.
import json
for row in range(len(data)):

The comment by @s29 should be an answer:
One way to add a directory to the virtual environment is to install virtualenvwrapper (which is useful for many things) and then do
mkvirtualenv myenv
workon myenv
add2virtualenv . #for current directory
add2virtualenv ~/my/path
If you want to remove these path edit the file myenvhomedir/lib/python2.7/site-packages/_virtualenv_path_extensions.pth
Documentation on virtualenvwrapper can be found at http://virtualenvwrapper.readthedocs.org/en/latest/
Specific documentation on this feature can be found at http://virtualenvwrapper.readthedocs.org/en/latest/command_ref.html?highlight=add2virtualenv
The auto_increment
property only works for numeric columns (integer and floating point), not char
columns:
CREATE TABLE discussion_topics (
topic_id INT NOT NULL AUTO_INCREMENT,
project_id char(36) NOT NULL,
topic_subject VARCHAR(255) NOT NULL,
topic_content TEXT default NULL,
date_created DATETIME NOT NULL,
date_last_post DATETIME NOT NULL,
created_by_user_id char(36) NOT NULL,
last_post_user_id char(36) NOT NULL,
posts_count char(36) default NULL,
PRIMARY KEY (topic_id)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 AUTO_INCREMENT=1;
You have to use RegExp object if your pattern is string
var xxx = "victoria";
var yyy = "i";
var rgxp = new RegExp(yyy, "g");
alert(xxx.match(rgxp).length);
If pattern is not dynamic string:
var xxx = "victoria";
var yyy = /i/g;
alert(xxx.match(yyy).length);
following Donald's comment:
This variable applies when binary logging is enabled.
All I had to do was:
That step out that import problem.
(Then I'll review the programmer's code to suggest an improvement)
grep -Fxq "$FILENAME" my_list.txt
The exit status is 0 (true) if the name was found, 1 (false) if not, so:
if grep -Fxq "$FILENAME" my_list.txt
then
# code if found
else
# code if not found
fi
Here are the relevant sections of the man page for grep
:
grep [options] PATTERN [FILE...]
-F
,--fixed-strings
Interpret PATTERN as a list of fixed strings, separated by newlines, any of which is to be matched.
-x
,--line-regexp
Select only those matches that exactly match the whole line.
-q
,--quiet
,--silent
Quiet; do not write anything to standard output. Exit immediately with zero status if any match is found, even if an error was detected. Also see the
-s
or--no-messages
option.
As rightfully pointed out in the comments, the above approach silently treats error cases as if the string was found. If you want to handle errors in a different way, you'll have to omit the -q
option, and detect errors based on the exit status:
Normally, the exit status is 0 if selected lines are found and 1 otherwise. But the exit status is 2 if an error occurred, unless the
-q
or--quiet
or--silent
option is used and a selected line is found. Note, however, that POSIX only mandates, for programs such asgrep
,cmp
, anddiff
, that the exit status in case of error be greater than 1; it is therefore advisable, for the sake of portability, to use logic that tests for this general condition instead of strict equality with 2.
To suppress the normal output from grep
, you can redirect it to /dev/null
. Note that standard error remains undirected, so any error messages that grep
might print will end up on the console as you'd probably want.
To handle the three cases, we can use a case
statement:
case `grep -Fx "$FILENAME" "$LIST" >/dev/null; echo $?` in
0)
# code if found
;;
1)
# code if not found
;;
*)
# code if an error occurred
;;

Done it, by a bit of creative programming,
Enum the Keys in HKEY_USERS for those funny number keys...
Enum the keys in HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList\
and you will find the same numbers.... Now in those keys look at the String value: ProfileImagePath = "SomeValue" where the values are either:
"%systemroot%\system32\config\systemprofile"... not interested in this one... as its not a directory path...
%SystemDrive%\Documents and Settings\LocalService - "Local Services" %SystemDrive%\Documents and Settings\NetworkService "NETWORK SERVICE"
or
%SystemDrive%\Documents and Settings\USER_NAME, which translates directly to the "USERNAME" values in most un-tampered systems, ie. where the user has not changed the their user name after a few weeks or altered the paths explicitly...
In my case it doesn't work, even with __DIR__
or getcwd()
it keeps picking the wrong path, I solved by defining a costant in every file I need with the absolute base path of the project:
if(!defined('THISBASEPATH')){ define('THISBASEPATH', '/mypath/'); }
require_once THISBASEPATH.'cache/crud.php';
/*every other require_once you need*/
I have MAMP with php 5.4.10 and my folder hierarchy is basilar:
q.php
w.php
e.php
r.php
cache/a.php
cache/b.php
setting/a.php
setting/b.php
....
This is slightly an edge case but I think it can add some value to the other answers.
If you add more details to the graph (say an annotation or a line) you'll soon discover that it is relevant when you call legend on the axis: if you call it at the bottom of the script it will capture different handles for the legend elements, messing everything.
For instance the following script:
df = pd.DataFrame({'A':26, 'B':20}, index=['N'])
ax = df.plot(kind='bar')
ax.hlines(23, -.5,.5, linestyles='dashed')
ax.annotate('average',(-0.4,23.5))
ax.legend(["AAA", "BBB"]); #quickfix: move this at the third line
Will give you this figure, which is wrong:
While this a toy example which can be easily fixed by changing the order of the commands, sometimes you'll need to modify the legend after several operations and hence the next method will give you more flexibility. Here for instance I've also changed the fontsize and position of the legend:
df = pd.DataFrame({'A':26, 'B':20}, index=['N'])
ax = df.plot(kind='bar')
ax.hlines(23, -.5,.5, linestyles='dashed')
ax.annotate('average',(-0.4,23.5))
ax.legend(["AAA", "BBB"]);
# do potentially more stuff here
h,l = ax.get_legend_handles_labels()
ax.legend(h[:2],["AAA", "BBB"], loc=3, fontsize=12)
This is what you'll get:
Just to add into alread given answers, the following worked for me:
HTML:
<div id="div{{$index+1}}" data-ng-show="val{{$index}}">
Where $index
is the loop index.
Javascript (where value
is the passed parameter to the function and it will be the value of $index
, current loop index):
var variable = "val"+value;
if ($scope[variable] === undefined)
{
$scope[variable] = true;
}else {
$scope[variable] = !$scope[variable];
}
This code should do the trick:
var array = ["ab", "abcdefgh", "abcd"];
array.sort(function(a, b){return b.length - a.length});
console.log(JSON.stringify(array, null, '\t'));
You can accomplish this via Maps. Something like
Map<String, String>[] arr = new HashMap<String, String>[2]();
arr[0].put("name", "demo");
But as you start using Java I am sure you will find that if you create a class/model that represents your data will be your best options. I would do
class Person{
String name;
String fname;
}
List<Person> people = new ArrayList<Person>();
Person p = new Person();
p.name = "demo";
p.fname = "fdemo";
people.add(p);
SELECT COUNT(*)
FROM `gd`
GROUP BY gid
HAVING COUNT(gid) > 10
ORDER BY lastupdated DESC;
EDIT (if you just want the gids):
SELECT MIN(gid)
FROM `gd`
GROUP BY gid
HAVING COUNT(gid) > 10
ORDER BY lastupdated DESC
I just noticed that this question is quite old. Nevertheless, I consider the following aspects to be worth adding:
Use MongoDB if you don't know yet how you're going to query your data.
MongoDB is suited for Hackathons, startups or every time you don't know how you'll query the data you inserted. MongoDB does not make any assumptions on your underlying schema. While MongoDB is schemaless and non-relational, this does not mean that there is no schema at all. It simply means that your schema needs to be defined in your app (e.g. using Mongoose). Besides that, MongoDB is great for prototyping or trying things out. Its performance is not that great and can't be compared to Redis.
Use Redis in order to speed up your existing application.
Redis can be easily integrated as a LRU cache. It is very uncommon to use Redis as a standalone database system (some people prefer referring to it as a "key-value"-store). Websites like Craigslist use Redis next to their primary database. Antirez (developer of Redis) demonstrated using Lamernews that it is indeed possible to use Redis as a stand alone database system.
Redis does not make any assumptions based on your data.
Redis provides a bunch of useful data structures (e.g. Sets, Hashes, Lists), but you have to explicitly define how you want to store you data. To put it in a nutshell, Redis and MongoDB can be used in order to achieve similar things. Redis is simply faster, but not suited for prototyping. That's one use case where you would typically prefer MongoDB. Besides that, Redis is really flexible. The underlying data structures it provides are the building blocks of high-performance DB systems.
Caching
Caching using MongoDB simply doesn't make a lot of sense. It would be too slow.
If you have enough time to think about your DB design.
You can't simply throw in your documents into Redis. You have to think of the way you in which you want to store and organize your data. One example are hashes in Redis. They are quite different from "traditional", nested objects, which means you'll have to rethink the way you store nested documents. One solution would be to store a reference inside the hash to another hash (something like key: [id of second hash]). Another idea would be to store it as JSON, which seems counter-intuitive to most people with a *SQL-background.
If you need really high performance.
Beating the performance Redis provides is nearly impossible. Imagine you database being as fast as your cache. That's what it feels like using Redis as a real database.
If you don't care that much about scaling.
Scaling Redis is not as hard as it used to be. For instance, you could use a kind of proxy server in order to distribute the data among multiple Redis instances. Master-slave replication is not that complicated, but distributing you keys among multiple Redis-instances needs to be done on the application site (e.g. using a hash-function, Modulo etc.). Scaling MongoDB by comparison is much simpler.
Prototyping, Startups, Hackathons
MongoDB is perfectly suited for rapid prototyping. Nevertheless, performance isn't that good. Also keep in mind that you'll most likely have to define some sort of schema in your application.
When you need to change your schema quickly.
Because there is no schema! Altering tables in traditional, relational DBMS is painfully expensive and slow. MongoDB solves this problem by not making a lot of assumptions on your underlying data. Nevertheless, it tries to optimize as far as possible without requiring you to define a schema.
TL;DR - Use Redis if performance is important and you are willing to spend time optimizing and organizing your data. - Use MongoDB if you need to build a prototype without worrying too much about your DB.

I did
git branch -f new_local_branch_name origin/remote_branch_name
Instead of
git branch -f new_local_branch_name upstream/remote_branch_name
As suggested by @innaM.
When I used the upstream version, it said 'fatal: Not a valid object name: 'upstream/remote_branch_name''. I did not do git fetch origin
as a comment suggested, but instead simply replaced upstream
with origin
. I guess they are equivalent.
The documentation (https://angular.io/guide/template-syntax#!#star-template) gives the following example. Say we have template code like this:
<hero-detail *ngIf="currentHero" [hero]="currentHero"></hero-detail>
Before it will be rendered, it will be "de-sugared". That is, the asterix notation will be transcribed to the notation:
<template [ngIf]="currentHero">
<hero-detail [hero]="currentHero"></hero-detail>
</template>
If 'currentHero' is truthy this will be rendered as
<hero-detail> [...] </hero-detail>
But what if you want an conditional output like this:
<h1>Title</h1><br>
<p>text</p>
.. and you don't want the output be wrapped in a container.
You could write the de-sugared version directly like so:
<template [ngIf]="showContent">
<h1>Title</h1>
<p>text</p><br>
</template>
And this will work fine. However, now we need ngIf to have brackets [] instead of an asterix *, and this is confusing (https://github.com/angular/angular.io/issues/2303)
For that reason a different notation was created, like so:
<ng-container *ngIf="showContent"><br>
<h1>Title</h1><br>
<p>text</p><br>
</ng-container>
Both versions will produce the same results (only the h1 and p tag will be rendered). The second one is preferred because you can use *ngIf like always.
Yes. In fact, all instance methods in Java are virtual by default. Only certain methods are not virtual:
Here are some examples:
"Normal" virtual functions
The following example is from an old version of the wikipedia page mentioned in another answer.
import java.util.*;
public class Animal
{
public void eat()
{
System.out.println("I eat like a generic Animal.");
}
public static void main(String[] args)
{
List<Animal> animals = new LinkedList<Animal>();
animals.add(new Animal());
animals.add(new Fish());
animals.add(new Goldfish());
animals.add(new OtherAnimal());
for (Animal currentAnimal : animals)
{
currentAnimal.eat();
}
}
}
class Fish extends Animal
{
@Override
public void eat()
{
System.out.println("I eat like a fish!");
}
}
class Goldfish extends Fish
{
@Override
public void eat()
{
System.out.println("I eat like a goldfish!");
}
}
class OtherAnimal extends Animal {}
Output:
I eat like a generic Animal. I eat like a fish! I eat like a goldfish! I eat like a generic Animal.
Example with virtual functions with interfaces
Java interface methods are all virtual. They must be virtual because they rely on the implementing classes to provide the method implementations. The code to execute will only be selected at run time.
For example:
interface Bicycle { //the function applyBrakes() is virtual because
void applyBrakes(); //functions in interfaces are designed to be
} //overridden.
class ACMEBicycle implements Bicycle {
public void applyBrakes(){ //Here we implement applyBrakes()
System.out.println("Brakes applied"); //function
}
}
Example with virtual functions with abstract classes.
Similar to interfaces Abstract classes must contain virtual methods because they rely on the extending classes' implementation. For Example:
abstract class Dog {
final void bark() { //bark() is not virtual because it is
System.out.println("woof"); //final and if you tried to override it
} //you would get a compile time error.
abstract void jump(); //jump() is a "pure" virtual function
}
class MyDog extends Dog{
void jump(){
System.out.println("boing"); //here jump() is being overridden
}
}
public class Runner {
public static void main(String[] args) {
Dog dog = new MyDog(); // Create a MyDog and assign to plain Dog variable
dog.jump(); // calling the virtual function.
// MyDog.jump() will be executed
// although the variable is just a plain Dog.
}
}
