Nobody has proposed this simple plain-text solution:
from pprint import pprint
pprint(s.to_dict())
which produces results like the following:
{'% Diabetes': 0.06365372374283895,
'% Obesity': 0.06365372374283895,
'% Bachelors': 0.0,
'% Poverty': 0.09548058561425843,
'% Driving Deaths': 1.1775938892425206,
'% Excessive Drinking': 0.06365372374283895}
Additionally, when using Jupyter notebooks, this is a great solution.
Note: pd.Series()
has no .to_html()
so it must be converted to pd.DataFrame()
from IPython.display import display, HTML
display(HTML(s.to_frame().to_html()))
which produces results like the following:
i have used following line of code & it works fine Thanks.... @Mithun Sasidharan **

Unfortunately this is a restriction of the Google maps service.
I am currently working on an application using the geocoding feature, and I'm saving each unique address on a per-user basis. I generate the address information (city, street, state, etc) based on the information returned by Google maps, and then save the lat/long information in the database as well. This prevents you from having to re-code things, and gives you nicely formatted addresses.
Another reason you want to do this is because there is a daily limit on the number of addresses that can be geocoded from a particular IP address. You don't want your application to fail for a person for that reason.
I had the same problem I used the solution offered above - I dropped the SYNONYM, created a VIEW with the same name as the synonym. it had a select using the dblink , and gave GRANT SELECT to the other schema It worked great.
The "evil" answer did not work for me. Instead, I used what was recommended on the JSHints docs page. If you know the warning that is thrown, you can turn it off for a block of code. For example, I am using some third party code that does not use camel case functions, yet my JSHint rules require it, which led to a warning. To silence it, I wrote:
/*jshint -W106 */
save_state(id);
/*jshint +W106 */
Try to open it with pandas:
import pandas as pd
data = pd.read_html('filename.xls')
Or try any other html python parser.
That's not a proper excel file, but an html readable with excel.
What did it for me is to edit the package file in the .idea folder as I accidentally added sources to this jar library and android couldn't resolve it by deleting the sources line as marked in the b/m picture library error.
Then rebuild the gradle and bam problem solved.
If you are using PHP's password_hash()
with the PASSWORD_DEFAULT
algorithm to generate the bcrypt hash (which I would assume is a large percentage of people reading this question) be sure to keep in mind that in the future password_hash()
might use a different algorithm as the default and this could therefore affect the length of the hash (but it may not necessarily be longer).
From the manual page:
Note that this constant is designed to change over time as new and stronger algorithms are added to PHP. For that reason, the length of the result from using this identifier can change over time. Therefore, it is recommended to store the result in a database column that can expand beyond 60 characters (255 characters would be a good choice).
Using bcrypt, even if you have 1 billion users (i.e. you're currently competing with facebook) to store 255 byte password hashes it would only ~255 GB of data - about the size of a smallish SSD hard drive. It is extremely unlikely that storing the password hash is going to be the bottleneck in your application. However in the off chance that storage space really is an issue for some reason, you can use PASSWORD_BCRYPT
to force password_hash()
to use bcrypt, even if that's not the default. Just be sure to stay informed about any vulnerabilities found in bcrypt and review the release notes every time a new PHP version is released. If the default algorithm is ever changed it would be good to review why and make an informed decision whether to use the new algorithm or not.
I'm using eclipse neon 3. I just wanted to use javafx.application.Application, so I followed Christian Hujer's answer above and it worked. Just some tips: the access rules are very similar to the import statement. For me, the access rules I added was "javafx/application/**". Just replace the dot in the import statement with forward slash and that's the rule. Hope that helps.
That would be the modulo operator, which produces the remainder of the division of two numbers.
Note that you can use the Polynomial class directly to do the fitting and return a Polynomial instance.
from numpy.polynomial import Polynomial
p = Polynomial.fit(x, y, 4)
plt.plot(*p.linspace())
p
uses scaled and shifted x values for numerical stability. If you need the usual form of the coefficients, you will need to follow with
pnormal = p.convert(domain=(-1, 1))
I also had this problem. I use chrome to code because I'm currently a newbie. I was able to change the colour of the checkboxes and radio selectors when they were checked ONLY using CSS. The current degree that is set in the hue-rotate() turns the blue checks red. I first used the grayscale(1) with the filter: but you don't need it. However, if you just want plain flat gray, go for the grayscale value for filter.
I've ONLY tested this in Chrome but it works with just plain old HTML and CSS, let me know in the comments section if it works in other browsers.
input[type="checkbox"],
input[type="radio"] {
filter: hue-rotate(140deg);
}
_x000D_

Why not implement your own replace?
void myReplace(std::string& str,
const std::string& oldStr,
const std::string& newStr)
{
std::string::size_type pos = 0u;
while((pos = str.find(oldStr, pos)) != std::string::npos){
str.replace(pos, oldStr.length(), newStr);
pos += newStr.length();
}
}
If you want to display links coming from your state or store in Vue 2.0, you can do like this:
<a v-bind:href="''">
{{ url_link }}

We have similar situation right now and as of this answer, I am using laravel 5.6 release.
I will not use your example in the question but mine, because it's related though.
I have route like this:
Route::name('your.name.here')->get('/your/uri', 'YourController@someMethod');
Then in your controller method, make sure you include
use Illuminate\Http\Request;
and this should be above your controller, most likely a default, if generated using php artisan
, now to get variable from the url it should look like this:
public function someMethod(Request $request)
{
$foo = $request->input("start");
$bar = $request->input("limit");
// some codes here
}
Regardless of the HTTP verb, the input() method may be used to retrieve user input.

I have a strong feeling that at the root of this "XY problem" the OP wanted just implode()
function.
Wildcards can only be used in the ServerAlias
rather than the ServerName
. Something which had me stumped.
For your use case, the following should suffice
<VirtualHost *:80>
ServerAlias *.example.com
VirtualDocumentRoot /var/www/%1/
</VirtualHost>
The following revision seeks to more clearly delineate PHP's array_filer(), array_map(), and array_walk(), all of which originate from functional programming:
array_filter() filters out data, producing as a result a new array holding only the desired items of the former array, as follows:
<?php
$array = array(1, "apples",2, "oranges",3, "plums");
$filtered = array_filter( $array, "ctype_alpha");
var_dump($filtered);
?>
live code here
All numeric values are filtered out of $array, leaving $filtered with only types of fruit.
array_map() also creates a new array but unlike array_filter() the resulting array contains every element of the input $filtered but with altered values, owing to applying a callback to each element, as follows:
<?php
$nu = array_map( "strtoupper", $filtered);
var_dump($nu);
?>
live code here
The code in this case applies a callback using the built-in strtoupper() but a user-defined function is another viable option, too. The callback applies to every item of $filtered and thereby engenders $nu whose elements contain uppercase values.
In the next snippet, array walk() traverses $nu and makes changes to each element vis a vis the reference operator '&'. The changes occur without creating an additional array. Every element's value changes in place into a more informative string specifying its key, category and value.
<?php
$f = function(&$item,$key,$prefix) {
$item = "$key: $prefix: $item";
};
array_walk($nu, $f,"fruit");
var_dump($nu);
?>
See demo
Note: the callback function with respect to array_walk() takes two parameters which will automatically acquire an element's value and its key and in that order, too when invoked by array_walk(). (See more here).
You can use like this:
removeDepartment(name: string): void {
this.departments = this.departments.filter(item => item != name);
}
Yes regex can certainly be used to extract part of a string. Unfortunately different flavours of *nix and different tools use slightly different Regex variants.
This sed command should work on most flavours (Tested on OS/X and Redhat)
echo '12 BBQ ,45 rofl, 89 lol' | sed 's/^.*,\([0-9][0-9]*\).*$/\1/g'
Simple! The folder named ..
is the parent folder, so you can make the path to the file you need as such
var foobar = require('../config/dev/foobar.json');
If you needed to go up two levels, you would write ../../
etc
Some more details about this in this SO answer and it's comments
Another solution is the xlsReadWrite
package, which doesn't require additional installs but does require you download the additional shlib before you use it the first time by :
require(xlsReadWrite)
xls.getshlib()
Forgetting this can cause utter frustration. Been there and all that...
On a sidenote : You might want to consider converting to a text-based format (eg csv) and read in from there. This for a number of reasons :
whatever your solution (RODBC, gdata, xlsReadWrite) some strange things can happen when your data gets converted. Especially dates can be rather cumbersome. The HFWutils
package has some tools to deal with EXCEL dates (per @Ben Bolker's comment).
if you have large sheets, reading in text files is faster than reading in from EXCEL.
for .xls and .xlsx files, different solutions might be necessary. EG the xlsReadWrite package currently does not support .xlsx AFAIK. gdata
requires you to install additional perl libraries for .xlsx support. xlsx
package can handle extensions of the same name.
If docker-compose
is installed for your user but not installed for root
user and if you need to run it only once and forget about it afterwords perform the next actions:
Find out path to docker-compose:
which docker-compose
Run the command specifying full path to docker-compose
from the previous command, eg:
sudo /home/your-user/your-path-to-compose/docker-compose up
Swift 5
if you have created UIBarButtonItem
in Interface Builder and you connected outlet to item and want to bind selector programmatically.
Don't forget to set target and selector.
addAppointmentButton.action = #selector(moveToAddAppointment)
addAppointmentButton.target = self
@objc private func moveToAddAppointment() {
self.presenter.goToCreateNewAppointment()
}
For those running in such issues right now, just try to put an alias for the table, this should the trick, e.g:
SELECT myvalue
INTO myvar
FROM mytable x
WHERE x.anothervalue = 1;
It worked for me.
Cheers.
I use this peace of code and I have successeful
<div class="row center-block">
<div style="margin: 0 auto;width: 90%;">
<div class="col-md-12" style="top:10px;">
</div>
<div class="col-md-12" style="top:10px;">
</div>
</div>
You can use BIGINT as follows:
CREATE TABLE user_reg (
user_id INT NOT NULL AUTO_INCREMENT,
identifier INT,
phone_number CHAR(11) NOT NULL,
verified TINYINT UNSIGNED NOT NULL,
reg_time BIGINT,
last_active_time BIGINT,
PRIMARY KEY (user_id),
INDEX (phone_number, user_id, identifier)
);
This is how I solved it. I forgot that sublist was a direct reference to the elements in the original list, so it makes sense why it wouldn't work.
ArrayList<Integer> inputA = new ArrayList<Integer>(input.subList(0, input.size()/2));
I had the following error message Port 80 in use by "Unable to open process" with PID 4! Apache WILL NOT start without the configured ports free! You need to uninstall/disable/reconfigure the blocking application or reconfigure Apache and the Control Panel to listen on a different port Starting Check-Timer Control Panel Ready
opened the httpd.conf and changed the listen port from 80 to 1234 in both places
Listen 1234
Then go to Config for the xampp control panel and go to service and port setting and changed the port from 80 to 1234
That worked.
Here is a solution using strings and converting it to decimal with ASCII tables:
#include <iostream>
#include <string>
#include "math.h"
using namespace std;
unsigned long hex2dec(string hex)
{
unsigned long result = 0;
for (int i=0; i<hex.length(); i++) {
if (hex[i]>=48 && hex[i]<=57)
{
result += (hex[i]-48)*pow(16,hex.length()-i-1);
} else if (hex[i]>=65 && hex[i]<=70) {
result += (hex[i]-55)*pow(16,hex.length( )-i-1);
} else if (hex[i]>=97 && hex[i]<=102) {
result += (hex[i]-87)*pow(16,hex.length()-i-1);
}
}
return result;
}
int main(int argc, const char * argv[]) {
string hex_str;
cin >> hex_str;
cout << hex2dec(hex_str) << endl;
return 0;
}
Try writing it in a new file..
f = open(filename, 'r+')
f2= open(filename2,'a+')
text = f.read()
text = re.sub('foobar', 'bar', text)
f.seek(0)
f.close()
f2.write(text)
fw.close()
If you are using PHP you can use file_get_contents()
to print the content:
<?php
$page = file_get_contents('https://www.google.com');
echo $page;
?>
This will print whatever content file_get_contents()
function gets in this url.
Please note that since you are displaying content as string instead as a actual web page, things like relative path images are not shown correctly, because /img/myimg.jpg is now loading from your server and not from google.com anymore.
However, you can play with some tricks like str_replace()
function to replace absolute urls in images:
<?php
$page = file_get_contents('https://www.google.com');
echo str_replace('src="img/','src="https://google.com/img/',$page);
?>

I have found that putting an '=' before the double quotes will accomplish what you want. It forces the data to be text.
eg. ="2008-10-03",="more text"
EDIT (according to other posts): because of the Excel 2007 bug noted by Jeffiekins one should use the solution proposed by Andrew: "=""2008-10-03"""
I recommend you take a look at the list of editors on Python's wiki, as well as these related questions:
Button inputs don't have a submit event. Try attaching the event handler to the form instead:
<script type="text/javascript">
$('#login_form').submit(function() {
$('#gif').show();
return true;
});
</script>
Arrays are different than ArrayList
s, on which you could call add
. You'll need an index first. Declare i
before the for
loop. Then you can use an array access expression to assign the element to the array.
num[i] = s;
i++;
UPDATE (2019-04-22) - It sounds like you want to use uncompyle6 nowadays rather than the answers I had mentioned originally.
This sounds like it works: http://code.google.com/p/unpyc/
Issue 8 says it supports 2.7: http://code.google.com/p/unpyc/updates/list
UPDATE (2013-09-03) - As noted in the comments and in other answers, you should look at https://github.com/wibiti/uncompyle2 or https://github.com/gstarnberger/uncompyle instead of unpyc.

Taking IdentityUser
would also work. This is a current user object and all values of user can be retrieved.

I'm was trying to do the same thing and it was bugging the crap out of me. In firefox, it appears that if you try to do some things when the escape key is pressed, it continues processing the escape key which then cancels whatever you were trying to do. Alert works fine. But in my case, I wanted to go back in the history which did not work. Finally figured out that I had to force the propagation of the event to stop as shown below...
if (keyCode == 27)
{
history.back();
if (window.event)
{
// IE works fine anyways so this isn't really needed
e.cancelBubble = true;
e.returnValue = false;
}
else if (e.stopPropagation)
{
// In firefox, this is what keeps the escape key from canceling the history.back()
e.stopPropagation();
e.preventDefault();
}
return (false);
}
In case anybody has tried to access tabs from within an iframe, you may notice it's not possible. The div
of the tab never gets marked as selected, just as hidden or not hidden. The link itself is the only piece marked as selected.
<li class="ui-state-default ui-corner-top ui-tabs-selected ui-state-active ui-state-focus"><a href="#tabs-4">Tab 5</a></li>
The following will get you the href
value of the link which should be the same as the id for your tab container:
jQuery('.ui-tabs-selected a',window.parent.document).attr('href')
This should also work in place of: $tabs.tabs('option', 'selected');
It's better in the sense that instead of just getting the index of the tab, it gives you the actual id of the tab.

Recently, I had a program batch processing files, I have certainly closed each file in the loop, but the error still there.
And later, I resolved this problem by garbage collect eagerly every hundreds of files:
int index;
while () {
try {
// do with outputStream...
} finally {
out.close();
}
if (index++ % 100 = 0)
System.gc();
}
I have really simple solution for this.
just create a new class
.noHover{
pointer-events: none;
}
and use this to disable any event on it. use it like:
<a href='' class='btn noHover'>You cant touch ME :P</a>
Simplest solution :
DateTime s = //some Datetime that you want to change time for 8:36:44 ;
s = new DateTime(s.Year, s.Month, s.Day, 8, 36, 44);
And if you need a specific Date and Time Format :
s = new DateTime(s.Year, s.Month, s.Day, 8, 36, 44).ToString("yyyy-MM-dd h:mm:ss");
Yes, it is absolutely possible to get the cookie from domain1.com by domain2.com. I had the same problem for a social plugin of my social network, and after a day of research I found the solution.
First, on the server side you need to have the following headers:
header("Access-Control-Allow-Origin: http://origin.domain:port");
header("Access-Control-Allow-Credentials: true");
header("Access-Control-Allow-Methods: GET, POST");
header("Access-Control-Allow-Headers: Content-Type, *");
Within the PHP-file you can use $_COOKIE[name]
Second, on the client side:
Within your ajax request you need to include 2 parameters
crossDomain: true
xhrFields: { withCredentials: true }
Example:
type: "get",
url: link,
crossDomain: true,
dataType: 'json',
xhrFields: {
withCredentials: true
}
Set the text of the button by setting the innerHTML
var b = document.createElement('button');
b.setAttribute('content', 'test content');
b.setAttribute('class', 'btn');
b.innerHTML = 'test value';
var wrapper = document.getElementById('divWrapper');
wrapper.appendChild(b);
You can accomplish this using the mysqldump command-line function.
For example:
If it's an entire DB, then:
$ mysqldump -u [uname] -p db_name > db_backup.sql
If it's all DBs, then:
$ mysqldump -u [uname] -p --all-databases > all_db_backup.sql
If it's specific tables within a DB, then:
$ mysqldump -u [uname] -p db_name table1 table2 > table_backup.sql
You can even go as far as auto-compressing the output using gzip (if your DB is very big):
$ mysqldump -u [uname] -p db_name | gzip > db_backup.sql.gz
If you want to do this remotely and you have the access to the server in question, then the following would work (presuming the MySQL server is on port 3306):
$ mysqldump -P 3306 -h [ip_address] -u [uname] -p db_name > db_backup.sql
It should drop the .sql
file in the folder you run the command-line from.
EDIT: Updated to avoid inclusion of passwords in CLI commands, use the -p
option without the password. It will prompt you for it and not record it.
This message means you're trying to compare a number and a string in a WHERE
or ON
clause. In your query, the only potential place where that could be occurring is ON ac.company_code = ta.company_code
; either make sure they have similar declarations, or use an explicit CAST
to convert the number to a string.
If you turn off strict
mode, the error should turn into a warning.
It is not possible to redirect a POST somewhere else. When you have POSTED the request, the browser will get a response from the server and then the POST is done. Everything after that is a new request. When you specify a location header in there the browser will always use the GET method to fetch the next page.
You could use some Ajax to submit the form in background. That way your form values stay intact. If the server accepts, you can still redirect to some other page. If the server does not accept, then you can display an error message, let the user correct the input and send it again.
Try:
var myUrl = "my.aspx?val=%2Fxyz2F";
var decodeUrl = System.Uri.UnescapeDataString(myUrl);
I had the same problem, but found out that the dump file was actually a MSSQL Server backup, not MySQL.
Sometimes legacy backup files play tricks on us. Check your dump file.
On terminal window:
~$ cat mybackup.dmp
The result was:
TAPE??G?"5,^}???Microsoft SQL ServerSPAD^LSFMB8..... etc...
To stop processing the cat command:
CTRL + C
In that example, e
is just a parameter for that function, but it's the event
object that gets passed in through it.
export PATH=/usr/pgsql-9.2/bin:$PATH
The program executable psql
is in the directory /usr/pgsql-9.2/bin
, and that directory is not included in the path by default, so we have to tell our shell (terminal) program where to find psql
. When most packages are installed, they are added to an existing path, such as /usr/local/bin
, but not this program.
So we have to add the program's path to the shell PATH variable if we do not want to have to type the complete path to the program every time we execute it.
This line should typically be added to theshell startup script, which for the bash shell will be in the file ~/.bashrc
.
You can also do something like this...
<input @input="myHandler('foo', 'bar', ...arguments)">
Evan You himself recommended this technique in one post on Vue forum. In general some events may emit more than one argument. Also as documentation states internal variable $event is meant for passing original DOM event.
I have scopes for this, hope it help somebody. https://laravel.com/docs/master/eloquent#local-scopes
public function scopeWhereLike($query, $column, $value)
{
return $query->where($column, 'like', '%'.$value.'%');
}
public function scopeOrWhereLike($query, $column, $value)
{
return $query->orWhere($column, 'like', '%'.$value.'%');
}
Usage:
$result = BookingDates::whereLike('email', $email)->orWhereLike('name', $name)->get();
find path -type f | xargs -L1 command
is all you need.
Although ctime isn't technically the time of creation, it quite often is.
Since ctime it isn't affected by changes to the contents of the file, it's usually only updated when the file is created. And yes - I can hear you all screaming - it's also updated if you change the access permissions or ownership... but generally that's something that's done once, usually at the same time you put the file there.
Personally I always use mtime for everything, and I imagine that is what you want. But anyway... here's a rehash of Guss's "unattractive" bash, in an easy to use function.
#!/bin/bash function age() { local filename=$1 local changed=`stat -c %Y "$filename"` local now=`date +%s` local elapsed let elapsed=now-changed echo $elapsed } file="/" echo The age of $file is $(age "$file") seconds.
Did you try list(x)??
y = '+123-456-7890'
c =list(y)
c
['+', '1', '2', '3', '-', '4', '5', '6', '-', '7', '8', '9', '0']
Microsoft Support says "Maximum URL length is 2,083 characters in Internet Explorer".
IE has problems with URLs longer than that. Firefox seems to work fine with >4k chars.
I use the following class. I found it on the Internet once, postulated to be the best NOW().
/// <summary>Class to get current timestamp with enough precision</summary>
static class CurrentMillis
{
private static readonly DateTime Jan1St1970 = new DateTime (1970, 1, 1, 0, 0, 0, DateTimeKind.Utc);
/// <summary>Get extra long current timestamp</summary>
public static long Millis { get { return (long)((DateTime.UtcNow - Jan1St1970).TotalMilliseconds); } }
}
Source unknown.
This is the syntax you need:
CASE WHEN countries LIKE '%'+@selCountry+'%' THEN 'national' ELSE 'regional' END
Although, as per your original problem, I'd solve it differently, splitting the content of @selcountry int a table form and joining to it.
Well, take care of what you mean by "between" too...
days_apart = (to - from).to_i # from + days_apart = to
total_days = (to - from).to_i + 1 # number of "selected" days
in_between_days = (to - from).to_i - 1 # how many days are in between from and to, i.e. excluding those two days
You can use the below change event to which will trigger when the combobox value will change.
Private Sub ComboBox1_Change()
'your code here
End Sub
Also you can get the selected value using below
ComboBox1.Value
If you run into this issue in a fairly complex app it can be cumbersome to refactor all your imports. PyCharm offers a quickfix for this that will automatically change all usage of the imported symbols as well.
Try this:
Dim s = "RAJAN"
Dim firstChar = s(0)
You can even do this:
Dim firstChar = "RAJAN"(0)
Such lookups are implemented in django.views.generic.date_based
as follows:
{'date_time_field__range': (datetime.datetime.combine(date, datetime.time.min),
datetime.datetime.combine(date, datetime.time.max))}
Because it is quite verbose there are plans to improve the syntax using __date
operator. Check "#9596 Comparing a DateTimeField to a date is too hard" for more details.
this is what i used:
NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
[dateFormat setDateFormat:@"yyyy-MM-dd"];
NSDateFormatter *timeFormat = [[NSDateFormatter alloc] init];
[timeFormat setDateFormat:@"HH:mm:ss"];
NSDate *now = [[NSDate alloc] init];
NSString *theDate = [dateFormat stringFromDate:now];
NSString *theTime = [timeFormat stringFromDate:now];
NSLog(@"\n"
"theDate: |%@| \n"
"theTime: |%@| \n"
, theDate, theTime);
[dateFormat release];
[timeFormat release];
[now release];
That seems to work for me:
<html>
<head><style>
#monkey {color:blue}
#ape {color:purple}
</style></head>
<body>
<span id="monkey" onclick="changeid()">
fruit
</span>
<script>
function changeid ()
{
var e = document.getElementById("monkey");
e.id = "ape";
}
</script>
</body>
</html>
The expected behaviour is to change the colour of the word "fruit".

Using ES6 syntax in React does not bind this
to user-defined functions however it will bind this
to the component lifecycle methods.
So the function that you declared will not have the same context as the class and trying to access this
will not give you what you are expecting.
For getting the context of class you have to bind the context of class to the function or use arrow functions.
Method 1 to bind the context:
class MyContainer extends Component {
constructor(props) {
super(props);
this.onMove = this.onMove.bind(this);
this.testVarible= "this is a test";
}
onMove() {
console.log(this.testVarible);
}
}
Method 2 to bind the context:
class MyContainer extends Component {
constructor(props) {
super(props);
this.testVarible= "this is a test";
}
onMove = () => {
console.log(this.testVarible);
}
}
Method 2 is my preferred way but you are free to choose your own.
Update: You can also create the properties on class without constructor:
class MyContainer extends Component {
testVarible= "this is a test";
onMove = () => {
console.log(this.testVarible);
}
}
Note If you want to update the view as well, you should use state
and setState
method when you set or change the value.
Example:
class MyContainer extends Component {
state = { testVarible: "this is a test" };
onMove = () => {
console.log(this.state.testVarible);
this.setState({ testVarible: "new value" });
}
}
Just to add to the other answers, the documentation gives this explanation:
KEY
is normally a synonym forINDEX
. The key attributePRIMARY KEY
can also be specified as justKEY
when given in a column definition. This was implemented for compatibility with other database systems.A
UNIQUE
index creates a constraint such that all values in the index must be distinct. An error occurs if you try to add a new row with a key value that matches an existing row. For all engines, aUNIQUE
index permits multipleNULL
values for columns that can containNULL
.A
PRIMARY KEY
is a unique index where all key columns must be defined asNOT NULL
. If they are not explicitly declared asNOT NULL
, MySQL declares them so implicitly (and silently). A table can have only onePRIMARY KEY
. The name of aPRIMARY KEY
is alwaysPRIMARY
, which thus cannot be used as the name for any other kind of index.
Using homebrew
install nvm
:
brew update
brew install nvm
source $(brew --prefix nvm)/nvm.sh
Add the last command to the .profile
, .bashrc
or .zshrc
file to not run it again on every terminal start. So for example to add it to the .profile
run:
echo "source $(brew --prefix nvm)/nvm.sh" >> ~/.profile
If you have trouble with installing nvm
using brew
you can install it manually (see here)
Using nvm
install node
or iojs
(you can install any version you want):
nvm install 0.10
# or
nvm install iojs-1.2.0
npm
is shipping with node
(or iojs
), so it will be available after installing node
(or iojs
). You may want to upgrade it to the latest version:
$ npm install -g npm@latest
UPD Previous version was . Thanks to @Metallica for pointing to the correct way (look at the comment bellow).npm update -g npm
Using npm
install ionic
:
npm install -g ionic
What about ngCordova
: you can install it using npm
or bower
. I don't know what variant is more fit for you, it depends on the package manager you want to use for the client side. So I'll describe them both:
Using npm
: Go to your project folder and install ng-cordova
in it:
npm install --save ng-cordova
Using bower
: Install bower:
npm install -g bower
And then go to your project folder and install ngCordova
in it:
bower install --save ngCordova
PS
npm install some_module
is npm i some_module
We've had similar problem and it was not enough to only remove commit and force push to GitLab.
It was still available in GitLab interface using url:
https://gitlab.example.com/<group>/<project>/commit/<commit hash>
We've had to remove project from GitLab and recreate it to get rid of this commit in GitLab UI.
Let's use
mysqli_connect
instead of
mysql_connect
because mysql_connect
isn't supported in PHP 7.
You have to declare your functions before main()
(or declare the function prototypes before main()
)
As it is, the compiler sees my_print (my_string);
in main()
as a function declaration.
Move your functions above main()
in the file, or put:
void my_print (char *);
void my_print2 (char *);
Above main()
in the file.
I have a simple script I use for this:
me@mycomputer:~$ cat /usr/local/bin/c
#!/bin/sh
echo "$*" | sed 's/x/\*/g' | bc -l
It changes x
to *
since *
is a special character in the shell. Use it as follows:
c 5x5
c 5-4.2 + 1
c '(5 + 5) * 30'
(you still have to use quotes if the expression contains any parentheses).When you specify the -Force
flag, PowerShell will not complain if the folder already exists.
One-liner:
Get-ChildItem D:\TopDirec\SubDirec\Project* | `
%{ Get-ChildItem $_.FullName -Filter Revision* } | `
%{ New-Item -ItemType Directory -Force -Path (Join-Path $_.FullName "Reports") }

I found you can do this easily via the Cloud Flare service.
Set up a bucket, enable webhosting on the bucket and point the desired CNAME to that endpoint via Cloudflare... and pay for the service of course... but $5-$20 VS $600 is much easier to stomach.
Full detail here: https://www.engaging.io/easy-way-to-configure-ssl-for-amazon-s3-bucket-via-cloudflare/
You can declare multiple type variables on a type or method. For example, using type parameters on the method:
<P, Q> int f(Set<P>, Set<Q>) {
return 0;
}
If you want to dynamically change it, I prefer using SqlConnectionStringBuilder .
It allows you to convert ConnectionString i.e. a string into class Object, All the connection string properties will become its Member.
In this case the real advantage would be that you don't have to worry about If the ConnectionTimeout string part is already exists in the connection string or not?
Also as it creates an Object and its always good to assign value in object rather than manipulating string.
Here is the code sample:
var sscsb = new SqlConnectionStringBuilder(_dbFactory.Database.ConnectionString);
sscsb.ConnectTimeout = 30;
var conn = new SqlConnection(sscsb.ConnectionString);
The above answers unfortunately don't quite work. In particular, the compile stage does not have access to scope, so you can't customize the field based on dynamic attributes. Using the linking stage seems to offer the most flexibility (in terms of asynchronously creating dom, etc.) The below approach addresses that:
<!-- Usage: -->
<form>
<form-field ng-model="formModel[field.attr]" field="field" ng-repeat="field in fields">
</form>
// directive
angular.module('app')
.directive('formField', function($compile, $parse) {
return {
restrict: 'E',
compile: function(element, attrs) {
var fieldGetter = $parse(attrs.field);
return function (scope, element, attrs) {
var template, field, id;
field = fieldGetter(scope);
template = '..your dom structure here...'
element.replaceWith($compile(template)(scope));
}
}
}
})
I've created a gist with more complete code and a writeup of the approach.
If you don't want line numbers shown all the time another way to find the line number of a piece of code is to just click in the left-most margin and create a breakpoint (a small blue arrow appears) then go to the breakpoint navigator (?7) where it will list the breakpoint with its line number. You can delete the breakpoint by right clicking on it.
That is the standard way to swap two variables, yes.
javascript uses dynamic arrays, no need to declare the size beforehand
you can push and shift to arrays as many times as you want, javascript will handle allocation and stuff for you
There is also a property resourceRef
of JndiObjectFactoryBean
that is, when set to true
, used to automatically prepend the string java:comp/env/
if it is not already present.
<bean id="someId" class="org.springframework.jndi.JndiObjectFactoryBean">
<property name="jndiName" value="jdbc/loc"/>
<property name="resourceRef" value="true"/>
</bean>
Put this on routes.php file:
\Event::listen('Illuminate\Database\Events\QueryExecuted', function ($query) {

var_dump($query->sql);
var_dump($query->bindings);
var_dump($query->time);
echo'</pre>';
});
Submitted by msurguy, source code in this page. You will find this fix-code for laravel 5.2 in comments.
Simplest way to do this is the following:
const arr = ['a','b','c'];
let obj = {}
function ConvertArr(arr) {
if (typeof(arr) === 'array') {
Object.assign(obj, arr);
}
This way it only runs if it is an array, however, you can run this with let global object variable or without, that's up to you, if you run without let, just do Object.assign({}, arr).
I had a slighlty different scenario. My checkboxes were created in dynamic and they were not of same group. But atleast any one of them had to be checked. My approach (never say this is perfect), I created a genric validator for all of them:
jQuery.validator.addMethod("validatorName", function(value, element) {
if (($('input:checkbox[name=chkBox1]:checked').val() == "Val1") ||
($('input:checkbox[name=chkBox2]:checked').val() == "Val2") ||
($('input:checkbox[name=chkBox3]:checked').val() == "Val3"))
{
return true;
}
else
{
return false;
}
}, "Please Select any one value");
Now I had to associate each of the chkbox to this one single validator.
Again I had to trigger the validation when any of the checkboxes were clicked triggering the validator.
$('#piRequest input:checkbox[name=chkBox1]').click(function(e){
$("#myform").valid();
});
yes.
var displayValue = document.getElementById('yourid').style.display;
{ "date" : "1000000" }
in your Mongo doc seems suspect. Since it's a number, it should be { date : 1000000 }
It's probably a type mismatch. Try post.findOne({date: "1000000"}, callback)
and if that works, you have a typing issue.
As MadScientist pointed out, you can export individual variables with:
export MY_VAR = foo # Available for all targets
Or export variables for a specific target (target-specific variables):
my-target: export MY_VAR_1 = foo
my-target: export MY_VAR_2 = bar
my-target: export MY_VAR_3 = baz
my-target: dependency_1 dependency_2
echo do something
You can also specify the .EXPORT_ALL_VARIABLES
target to—you guessed it!—EXPORT ALL THE THINGS!!!:
.EXPORT_ALL_VARIABLES:
MY_VAR_1 = foo
MY_VAR_2 = bar
MY_VAR_3 = baz
test:
@echo $$MY_VAR_1 $$MY_VAR_2 $$MY_VAR_3
Or perhaps you could use this class:
http://developer.android.com/reference/java/net/URLEncoder.html
Which is present in Android since API level 1.
Annoyingly however, it treats spaces specially (replacing them with + instead of %20). To get round this we simply use this fragment:
URLEncoder.encode(value, "UTF-8").replace("+", "%20");

Using jQuery data() to store data

Use a server implementation to send messages to your client and use data type of messages rather than notification type of messages.
This will help you get a callback to onMessageReceived
irrespective if your app is in background or foreground and you can generate your custom notification then
As other people have answered, .cshtml
(or .vbhtml
if that's your flavor) provides a handler-mapping to load the MVC engine. The .aspx
extension simply loads the aspnet_isapi.dll that performs the compile and serves up web forms. The difference in the handler mapping is simply a method of allowing the two to co-exist on the same server allowing both MVC applications and WebForms applications to live under a common root.
This allows http://www.mydomain.com/MyMVCApplication to be valid and served with MVC rules along with http://www.mydomain.com/MyWebFormsApplication to be valid as a standard web form.
Edit:
As for the difference in the technologies, the MVC (Razor) templating framework is intended to return .Net pages to a more RESTful "web-based" platform of templated views separating the code logic between the model (business/data objects), the view (what the user sees) and the controllers (the connection between the two). The WebForms model (aspx) was an attempt by Microsoft to use complex javascript embedding to simulate a more stateful application similar to a WinForms application complete with events and a page lifecycle that would be capable of retaining its own state from page to page.
The choice to use one or the other is always going to be a contentious one because there are arguments for and against both systems. I for one like the simplicity in the MVC architecture (though routing is anything but simple) and the ease of the Razor syntax. I feel the WebForms architecture is just too heavy to be an effective web platform. That being said, there are a lot of instances where the WebForms framework provides a very succinct and usable model with a rich event structure that is well defined. It all boils down to the needs of the application and the preferences of those building it.

As @user3483203 pointed out, numpy.select is the best approach
Store your conditional statements and the corresponding actions in two lists
conds = [(df['eri_hispanic'] == 1),(df[['eri_afr_amer', 'eri_asian', 'eri_hawaiian', 'eri_nat_amer', 'eri_white']].sum(1).gt(1)),(df['eri_nat_amer'] == 1),(df['eri_asian'] == 1),(df['eri_afr_amer'] == 1),(df['eri_hawaiian'] == 1),(df['eri_white'] == 1,])
actions = ['Hispanic', 'Two Or More', 'A/I AK Native', 'Asian', 'Black/AA', 'Haw/Pac Isl.', 'White']
You can now use np.select using these lists as its arguments
df['label_race'] = np.select(conds,actions,default='Other')

To remove a timezone (tzinfo) from a datetime object:
# dt_tz is a datetime.datetime object
dt = dt_tz.replace(tzinfo=None)
If you are using a library like arrow, then you can remove timezone by simply converting an arrow object to to a datetime object, then doing the same thing as the example above.
# <Arrow [2014-10-09T10:56:09.347444-07:00]>
arrowObj = arrow.get('2014-10-09T10:56:09.347444-07:00')
# datetime.datetime(2014, 10, 9, 10, 56, 9, 347444, tzinfo=tzoffset(None, -25200))
tmpDatetime = arrowObj.datetime
# datetime.datetime(2014, 10, 9, 10, 56, 9, 347444)
tmpDatetime = tmpDatetime.replace(tzinfo=None)
Why would you do this? One example is that mysql does not support timezones with its DATETIME type. So using ORM's like sqlalchemy will simply remove the timezone when you give it a datetime.datetime
object to insert into the database. The solution is to convert your datetime.datetime
object to UTC (so everything in your database is UTC since it can't specify timezone) then either insert it into the database (where the timezone is removed anyway) or remove it yourself. Also note that you cannot compare datetime.datetime
objects where one is timezone aware and another is timezone naive.
##############################################################################
# MySQL example! where MySQL doesn't support timezones with its DATETIME type!
##############################################################################
arrowObj = arrow.get('2014-10-09T10:56:09.347444-07:00')
arrowDt = arrowObj.to("utc").datetime
# inserts datetime.datetime(2014, 10, 9, 17, 56, 9, 347444, tzinfo=tzutc())
insertIntoMysqlDatabase(arrowDt)
# returns datetime.datetime(2014, 10, 9, 17, 56, 9, 347444)
dbDatetimeNoTz = getFromMysqlDatabase()
# cannot compare timzeone aware and timezone naive
dbDatetimeNoTz == arrowDt # False, or TypeError on python versions before 3.3
# compare datetimes that are both aware or both naive work however
dbDatetimeNoTz == arrowDt.replace(tzinfo=None) # True
There is way without requiring user to do changes on his PC. Runtime.getRuntime.exec() allows us to start cmd.exe and execute commands inside of it. So, it's possible for java program to run itself in command prompt when user clicks .jar file.
public static void main(String[] args) throws IOException {
if(args.length == 0) {
Process p = Runtime.getRuntime().exec("cmd.exe /c start java -jar " + (new File(NameOfClass.class.getProtectionDomain().getCodeSource().getLocation().getPath())).getAbsolutePath() + " cmd");
} else {
//code to be executed

}
If you're using Python 3, just execute python3 get-pip.py

In Python, you can do it the same way we do it with mobile application
web.open('https://web.whatsapp.com/send?phone='+phone_no+'&text='+message)
This will prepopulate the text for given mobile number(Enter the phone_no as CountryCode and the number eg +918888888888) Then using pyautogui you can press enter onto whatsapp.web
Working code :
def sendwhatmsg(phone_no, message, time_hour, time_min):
'''Sends whatsapp message to a particulal number at given time'''
if time_hour == 0:
time_hour = 24
callsec = (time_hour*3600)+(time_min*60)
curr = time.localtime()
currhr = curr.tm_hour
currmin = curr.tm_min
currsec = curr.tm_sec
currtotsec = (currhr*3600)+(currmin*60)+(currsec)
lefttm = callsec-currtotsec
if lefttm <= 0:
lefttm = 86400+lefttm
if lefttm < 60:
raise Exception("Call time must be greater than one minute")
else:
sleeptm = lefttm-60
time.sleep(sleeptm)
web.open('https://web.whatsapp.com/send?phone='+phone_no+'&text='+message)
time.sleep(60)
pg.press('enter')

On iOS 9.1+ n iOS 9.2+ go to Settings -> General -> Device Management -> press the Profile -> Press Trust.
The solution may be java.lang.String.format("%" + maxlength + "s", string).trim()
, like this:
int maxlength = 20;
String longString = "Any string you want which length is greather than 'maxlength'";
String shortString = "Anything short";
String resultForLong = java.lang.String.format("%" + maxlength + "s", longString).trim();
String resultForShort = java.lang.String.format("%" + maxlength + "s", shortString).trim();
System.out.println(resultForLong);
System.out.println(resultForShort);

For example I'm working on small function which prints stars in pyramid format upon passing the number as argument, although you can accomplish this using end="" to print in a separate line, I used sys.stdout.write in co-ordination with print to make this work. To elaborate on this stdout.write prints in the same line where as print always prints its contents in a separate line.
import sys
def printstars(count):
if count >= 1:
i = 1
while (i <= count):
x=0
while(x<i):
sys.stdout.write('*')
x = x+1
print('')
i=i+1
printstars(5)
No, you don't need to add them as a remote. That would be clumbersome and a pain to do each time.
git fetch [email protected]:theirusername/reponame.git theirbranch:ournameforbranch
This creates a local branch named ournameforbranch
which is exactly the same as what theirbranch
was for them. For the question example, the last argument would be foo:foo
.
Note :ournameforbranch
part can be further left off if thinking up a name that doesn't conflict with one of your own branches is bothersome. In that case, a reference called FETCH_HEAD
is available. You can git log FETCH_HEAD
to see their commits then do things like cherry-picked
to cherry pick their commits.
Oftentimes, you want to fix something of theirs and push it right back. That's possible too:
git fetch [email protected]:theirusername/reponame.git theirbranch
git checkout FETCH_HEAD
# fix fix fix
git push [email protected]:theirusername/reponame.git HEAD:theirbranch
If working in detached state worries you, by all means create a branch using :ournameforbranch
and replace FETCH_HEAD
and HEAD
above with ournameforbranch
.
Assertions are generally used primarily as a means of checking the program's expected behavior. It should lead to a crash in most cases, since the programmer's assumptions about the state of the program are false. This is where the debugging aspect of assertions come in. They create a checkpoint that we simply can't ignore if we would like to have correct behavior.
In your case it does data validation on the incoming parameters, though it does not prevent clients from misusing the function in the future. Especially if they are not, (and should not) be included in release builds.
Do you want the input fields to be centered? A trick to center elements: specify the width of the element and set the margin to auto, eg:
margin : 0px auto;
width:300px
A link to your updated fiddle:
You can do it in 2 steeps:
1. Use the checkout
for create the local branch:
git checkout -b yourBranchName
Work with your Branch as you want.
2. Use the push
command to autocreate the branch and send the code to the remote repository:
git push -u origin yourBanchName
There are mutiple ways to do this but I think that this way is really simple.
Check your all 3:
in the php.ini configuration file
* for those, who are using wamp @windows, you can follow these steps: *
Also it can be adapted to any phpmyadmin installation.
Find your config.inc.php file for PhpMyAdmin configuration (for wamp it's here: C:\wamp\apps\phpmyadminVERSION\config.inc.php
add this line at the end of the file BEFORE "?>":
$cfg['UploadDir'] = 'C:\wamp\sql';
save
create folder at
C:\wamp\sql
copy your huge sql file there.
Restart server.
Go to your phpmyadmin import tab and you'll see a list of files uploaded to c:\wamp\sql folder.
Paste this code in any of your source files and re-build. Worked for me !
#include stdio.h
FILE _iob[3];
FILE* __cdecl __iob_func(void) {
_iob[0] = *stdin;
_iob[0] = *stdout;
_iob[0] = *stderr;
return _iob;
}
If you don't mind the set to be sorted then you may be interested to take a look at the indexed-tree-map project.
The enhanced TreeSet/TreeMap provides access to elements by index or getting the index of an element. And the implementation is based on updating node weights in the RB tree. So no iteration or backing up by a list here.
Starting in MongoDB 3.4, you can use the $sortByCount
aggregation.
Groups incoming documents based on the value of a specified expression, then computes the count of documents in each distinct group.
https://docs.mongodb.com/manual/reference/operator/aggregation/sortByCount/
For example:
db.contest.aggregate([
{ $sortByCount: "$province" }
]);
I have used this one on MySQL, MS Access and SQL Server. The id fields are the fields on wich the tables coincide, not necesarily the primary index.
UPDATE DestTable INNER JOIN SourceTable ON DestTable.idField = SourceTable.idField SET DestTable.Field1 = SourceTable.Field1, DestTable.Field2 = SourceTable.Field2...
I think that this code is going to help:
JS:
$('#foo').ready(function () {
$('#loadingMessage').css('display', 'none');
});
$('#foo').load(function () {
$('#loadingMessage').css('display', 'none');
});
HTML:
<iframe src="http://google.com/" id="foo"></iframe>
<div id="loadingMessage">Loading...</div>
CSS:
#loadingMessage {
width: 100%;
height: 100%;
z-index: 1000;
background: #ccc;
top: 0px;
left: 0px;
position: absolute;
}
Just for the heck of it, I tracked this down in the jQuery code. The .val() function currently starts at line 165 of attributes.js. Here's the relevant section, with my annotations:
val: function( value ) {
var hooks, ret, isFunction,
elem = this[0];
/// NO ARGUMENTS, BECAUSE NOT SETTING VALUE
if ( !arguments.length ) {
/// IF NOT DEFINED, THIS BLOCK IS NOT ENTERED. HENCE 'UNDEFINED'
if ( elem ) {
hooks = jQuery.valHooks[ elem.type ] || jQuery.valHooks[ elem.nodeName.toLowerCase() ];
if ( hooks && "get" in hooks && (ret = hooks.get( elem, "value" )) !== undefined ) {
return ret;
}
ret = elem.value;
/// IF IS DEFINED, JQUERY WILL CHECK TYPE AND RETURN APPROPRIATE 'EMPTY' VALUE
return typeof ret === "string" ?
// handle most common string cases
ret.replace(rreturn, "") :
// handle cases where value is null/undef or number
ret == null ? "" : ret;
}
return;
}
So, you'll either get undefined
or ""
or null
-- all of which evaluate as false in if statements.
CREATE [TEMPORARY] TABLE [IF NOT EXISTS] tbl_name
[(create_definition,...)]
[table_options]
select_statement
Example :
CREATE TEMPORARY TABLE IF NOT EXISTS mytable
(id int(11) NOT NULL, PRIMARY KEY (id)) ENGINE=MyISAM;
INSERT IGNORE INTO mytable SELECT id FROM table WHERE xyz;
the instanceOf
statement is often used in implementation of equals.
This is a popular pitfall !
The problem is that using instanceOf
violates the rule of symmetry:
(object1.equals(object2) == true)
if and only if (object2.equals(object1))
if the first equals is true, and object2 is an instance of a subclass of the class where obj1 belongs to, then the second equals will return false!
if the regarded class where ob1 belongs to is declared as final, then this problem can not arise, but in general, you should test as follows:
this.getClass() != otherObject.getClass();
if not, return false, otherwise test
the fields to compare for equality!
Yes, this is something that you should worry about. Check the length of your objects with nrow(). R can auto-replicate objects so that they're the same length if they differ, which means you might be performing operations on mismatched data.
In this case you have an obvious flaw in that your subtracting aggregated data from raw data. These will definitely be of different lengths. I suggest that you merge them as time series (using the dates), then locf(), then do your subtraction. Otherwise merge them by truncating the original dates to the same interval as the aggregated series. Just be very careful that you don't drop observations.
Lastly, as some general advice as you get started: look at the result of your computations to see if they make sense. You might even pull them into a spreadsheet and replicate the results.
This will tell you what line is the problem.
import csv
lines = []
with open('output.txt','r') as f:
for line in f.readlines():
lines.append(line[:-1])
with open('corrected.csv','w') as correct:
writer = csv.writer(correct, dialect = 'excel')
with open('input.csv', 'r') as mycsv:
reader = csv.reader(mycsv)
try:
for i, row in enumerate(reader):
if row[0] not in lines:
writer.writerow(row)
except csv.Error:
print('csv choked on line %s' % (i+1))
raise
Perhaps this from daniweb would be helpful:
I'm getting this error when reading from a csv file: "Runtime Error! line contains NULL byte". Any idea about the root cause of this error?
...
Ok, I got it and thought I'd post the solution. Simply yet caused me grief... Used file was saved in a .xls format instead of a .csv Didn't catch this because the file name itself had the .csv extension while the type was still .xls
MATLAB is, first and foremost, a commercial offering. Therefore, everything in MATLAB pretty much works out of the box. All the core functionality is solid, and if you're working on a special project then MATLAB probably has an add-on they can sell you that adds a lot of additional domain-specific .m files for you. It ain't cheap, but it works and it will get the job done without complaint.
Octave always shows its open-source, information-wants-to-be-free roots. It's free, and it will remind you that it's free at every opportunity. It's developed by volunteers who hate Windows with a passion. Therefore Octave runs on Windows grudgingly. It's quite surprising that as many MATLAB features exist as they do.
But here's the rub. Anytime you try to do something more than trivially complex, Octave suddenly breaks in subtle and hard to understand ways. Oops -- the terminal driver had an overflow somewhere deep in the OpenGL layer. You can't print. Oops -- the figure plots do strange things with their fonts. Good luck figuring out why. Oops -- there's some hidden dependency between Octave and some other obscure bit of free software, so it won't compile. Good luck figuring out which it is.
And the Octave response is hey! It's free software! You have all the source code, you can fix all those bugs yourself! Maybe if I had infinite time and resources on my hands, I could spend all my time fixing bugs in free software, but I personally don't. If I worked in academia, I might.
So at the core, the issue of whether to choose MATLAB or Octave comes down to one question. Interestingly, that question is always the same, when choosing between commercial vs. free software variants.
And the question is:
Do you have more money than time?
I solved my problem with fallow this steps =>
When dealing with strings often I find it easier to make the source file ObjC++, then I can concatenate std::strings using the second method shown in the question.
std::string stdstr = [nsstr UTF8String];
//easier to read and more portable string manipulation goes here...
NSString* nsstr = [NSString stringWithUTF8String:stdstr.c_str()];
You can use IList(Of String)
in the function :
Private Function getWriteBits() As IList(Of String)
Dim temp1 As String
Dim temp2 As Boolean
Dim temp3 As Boolean
'Pallet Destination Unique
Dim temp4 As Boolean
Dim temp5 As Boolean
Dim temp6 As Boolean
Dim lstWriteBits As Ilist = {temp1, temp2, temp3, temp4, temp5, temp6}
Return lstWriteBits
End Function
use
list1.AddRange(list2)
to add lists
Hope it helps.
You are using a local path. Is that really what you want? If it is, you need to use the file:///
prefix:
file:///H:/media/css/static/img/sprites/buttons-v3-10.png
obviously, this will work only on your local computer.
Also, in many modern browsers, this works only if the page itself is also on a local file path. Addressing local files from remote (http://
, https://
) pages has been widely disabled due to security reasons.
using maxlength attribute of textarea would do the trick ... simple html code .. not JS or JQuery or Server Side Check Required....
All good answers...From the validation perspective, I also noticed that MaxLength gets validated at the server side only, while StringLength gets validated at client side too.
Just to complete Amit Garg answer, there are several ways to inject dependencies in AngularJS.
You can also use $inject
to add a dependency:
var MyController = function($scope, $http) {
// ...
}
MyController.$inject = ['$scope', '$http'];

var value = $('#SecondSelect')[0].value;
Depending on what kind of image you have, it might be better to rework the design so that the main image fades to a set solid color or repeatable pattern. If you center the image in the page and have the solid color as the backgroud.

I'd like to suggest a variant of the original question, "What does Ruby have that Python doesn't, and vice versa?" which admits the disappointing answer, "Well, what can you do with either Ruby or Python that can't be done in Intercal?" Nothing on that level, because Python and Ruby are both part of the vast royal family sitting on the throne of being Turing approximant.
But what about this:
What can be done gracefully and well in Python that can't be done in Ruby with such beauty and good engineering, or vice versa?
That may be much more interesting than mere feature comparison.
Yes, it is possible.

The "as" keyword is used to assign the error to a variable so that the error can be investigated more thoroughly later on in the code. Also note that the parentheses for the triple exception case are needed in python 3. This page has more info: Catch multiple exceptions in one line (except block)
@skaffman nailed it down. They live each in its own context. However, I wouldn't consider using scriptlets as the solution. You'd like to avoid them. If all you want is to concatenate strings in EL and you discovered that the +
operator fails for strings in EL (which is correct), then just do:
<c:out value="abc${test}" />
Or if abc
is to obtained from another scoped variable named ${resp}
, then do:
<c:out value="${resp}${test}" />
I was running into this error while converting from nvarchar to float.
What I had to do was to use the LEFT
function on the nvarchar field.
Example: Left(Field,4)
Basically, the query will look like:
Select convert(float,left(Field,4)) from TABLE
Just ridiculous that SQL would complicate it to this extent, while with C# it's a breeze!
Hope it helps someone out there.
The original question (first part) was "how to check environment variables in Python."
Here's how to check if $FOO is set:
try:

Hi first give an id to the select as
<select id=theid>
<option value="test">label </option>
</select>
then you can call the selected label like that:
jQuery('#theid option:selected').text()
Copy the diff file to the root of your repository, and then do:
git apply yourcoworkers.diff
More information about the apply
command is available on its man page.
By the way: A better way to exchange whole commits by file is the combination of the commands git format-patch
on the sender and then git am
on the receiver, because it also transfers the authorship info and the commit message.
If the patch application fails and if the commits the diff was generated from are actually in your repo, you can use the -3
option of apply
that tries to merge in the changes.
It also works with Unix pipe as follows:
git diff d892531 815a3b5 | git apply
When I was a beginner I found these descriptions a bit intimidating. As at first I would try
For Windows
f= open('C:\Users\chidu\Desktop\Skipper New\Special_Note.txt','w+')
print(f)
and this would raise an syntax error
. I used get confused alot. Then after some surfing across google. found why the error occurred. Writing this for beginners
It's because for path to be read in Unicode you simple add a \
when starting file path
f= open('C:\\Users\chidu\Desktop\Skipper New\Special_Note.txt','w+')
print(f)
And now it works just add \
before starting the directory.
Users\ your user name \
Increment a counter every time you render a screen and clear that counter for some time interval over which you want to measure the frame-rate.
Ie. Every 3 seconds, get counter/3 and then clear the counter.
In CSS, for the font-weight
property, the value: normal
defaults to the numeric value 400, and bold
to 700.
If you want to specify other weights, you need to give the number value. That number value needs to be supported for the font family that you are using.
For example you would define semi-bold like this:
font-weight: 600;
Here an JSFiddle using 'Open Sans' font family, loaded with the above weights.
First let's understand what big O, big Theta and big Omega are. They are all sets of functions.
Big O is giving upper asymptotic bound, while big Omega is giving a lower bound. Big Theta gives both.
Everything that is ?(f(n))
is also O(f(n))
, but not the other way around.
T(n)
is said to be in ?(f(n))
if it is both in O(f(n))
and in Omega(f(n))
.
In sets terminology, ?(f(n))
is the intersection of O(f(n))
and Omega(f(n))
For example, merge sort worst case is both O(n*log(n))
and Omega(n*log(n))
- and thus is also ?(n*log(n))
, but it is also O(n^2)
, since n^2
is asymptotically "bigger" than it. However, it is not ?(n^2)
, Since the algorithm is not Omega(n^2)
.
O(n)
is asymptotic upper bound. If T(n)
is O(f(n))
, it means that from a certain n0
, there is a constant C
such that T(n) <= C * f(n)
. On the other hand, big-Omega says there is a constant C2
such that T(n) >= C2 * f(n))
).
Not to be confused with worst, best and average cases analysis: all three (Omega, O, Theta) notation are not related to the best, worst and average cases analysis of algorithms. Each one of these can be applied to each analysis.
We usually use it to analyze complexity of algorithms (like the merge sort example above). When we say "Algorithm A is O(f(n))
", what we really mean is "The algorithms complexity under the worst1 case analysis is O(f(n))
" - meaning - it scales "similar" (or formally, not worse than) the function f(n)
.
Well, there are many reasons for it, but I believe the most important of them are:
To demonstrate this issue, have a look at the following graphs:
It is clear that f(n) = 2*n
is "worse" than f(n) = n
. But the difference is not quite as drastic as it is from the other function. We can see that f(n)=logn
quickly getting much lower than the other functions, and f(n) = n^2
is quickly getting much higher than the others.
So - because of the reasons above, we "ignore" the constant factors (2* in the graphs example), and take only the big-O notation.
In the above example, f(n)=n, f(n)=2*n
will both be in O(n)
and in Omega(n)
- and thus will also be in Theta(n)
.
On the other hand - f(n)=logn
will be in O(n)
(it is "better" than f(n)=n
), but will NOT be in Omega(n)
- and thus will also NOT be in Theta(n)
.
Symetrically, f(n)=n^2
will be in Omega(n)
, but NOT in O(n)
, and thus - is also NOT Theta(n)
.
1Usually, though not always. when the analysis class (worst, average and best) is missing, we really mean the worst case.
Similar to the above, remember that you could have miniconda
instead of conda, so you might want to add
export PATH=${PATH}:/Users/davidfortini/miniconda3/bin
to .zshrc
or .bash_profile
and then reboot the terminal.
I would like to add some additional aspect of this discussion. In windows OS I have observed that when a jar file containing schema is stored in a directory whose path contains a space character, for instance like in the following example
"c:\Program Files\myApp\spring-beans-4.0.2.RELEASE.jar"
then specifying schema location URL in the following way is not sufficient when you are developing some standalone application that should work also offline
<beans
xsi:schemaLocation="
http://www.springframework.org/schema/beans org/springframework/beans/factory/xml/spring-beans-2.0.xsd"
/>
I have learned that result of such schema location URL resolution is a file which has a path like the following
"c:\Program%20Files\myApp\spring-beans-4.0.2.RELEASE.jar"
When I started my application from some other directory which didn't contain space character on its path then schema location resolution worked fine. Maybe somebody faced similar problems? Nevertheless I discoverd that classpath protocol works fine in my case
<beans
xsi:schemaLocation="
http://www.springframework.org/schema/beans classpath:org/springframework/beans/factory/xml/spring-beans-2.0.xsd"
/>
Last-Modified : The last modified date for the requested object
If-Modified-Since : Allows a 304 Not Modified to be returned if last modified date is unchanged.
ETag : An ETag is an opaque identifier assigned by a web server to a specific version of a resource found at a URL. If the resource representation at that URL ever changes, a new and different ETag is assigned.
If-None-Match : Allows a 304 Not Modified to be returned if ETag is unchanged.
the browser store cache with a date(Last-Modified) or id(ETag), when you need to request the URL again, the browser send request message with the header:
the server will return 304 when the if statement is False, and browser will use cache.
I'd use this approach:
String randomString(final int length) {
Random r = new Random(); // perhaps make it a class variable so you don't make a new one every time
StringBuilder sb = new StringBuilder();
for(int i = 0; i < length; i++) {
char c = (char)(r.nextInt((int)(Character.MAX_VALUE)));
sb.append(c);
}
return sb.toString();
}
If you want a byte[] you can do this:
byte[] randomByteString(final int length) {
Random r = new Random();
byte[] result = new byte[length];
for(int i = 0; i < length; i++) {
result[i] = r.nextByte();
}
return result;
}
Or you could do this
byte[] randomByteString(final int length) {
Random r = new Random();
StringBuilder sb = new StringBuilder();
for(int i = 0; i < length; i++) {
char c = (char)(r.nextInt((int)(Character.MAX_VALUE)));
sb.append(c);
}
return sb.toString().getBytes();
}
set the target
attribute of your <a>
element to "_tab"
EDIT: It works, however W3Schools says there is no such target attribute: http://www.w3schools.com/tags/att_a_target.asp
EDIT2: From what I've figured out from the comments. setting target to _blank will take you to a new tab or window (depending on your browser settings). Typing anything except one of the ones below will create a new tab group (I'm not sure how these work):
_blank Opens the linked document in a new window or tab
_self Opens the linked document in the same frame as it was clicked (this is default)
_parent Opens the linked document in the parent frame
_top Opens the linked document in the full body of the window
framename Opens the linked document in a named frame
I know this question is old. But this might be useful for someone who is having the problem with legend. In addition to the answer given by ZaneDarken, I modified the chart.js file to show the legend in my pie chart. I changed the legendTemplate(which is declared many times for every chart type) just above these lines :
Chart.Type.extend({_x000D_
//Passing in a name registers this chart in the Chart namespace_x000D_
name: "Doughnut",_x000D_
//Providing a defaults will also register the deafults in the chart namespace_x000D_
defaults: defaultConfig,_x000D_
.......
_x000D_
My legendTemplate is changed from
legendTemplate : "_x000D_
<ul class=\ "<%=name.toLowerCase()%>-legend\">_x000D_
<% for (var i=0; i<datasets.length; i++){%>_x000D_
<li><span style=\ "background-color:<%=datasets[i].strokeColor%>\"></span>_x000D_
<%if(datasets[i].label){%>_x000D_
<%=datasets[i].label%>_x000D_
<%}%>_x000D_
</li>_x000D_
<%}%>_x000D_
</ul>"
_x000D_
To
legendTemplate: "_x000D_
<ul class=\ "<%=name.toLowerCase()%>-legend\">_x000D_
<% for (var i=0; i<segments.length; i++){%>_x000D_
<li><span style=\ "-moz-border-radius:7px 7px 7px 7px; border-radius:7px 7px 7px 7px; margin-right:10px;width:15px;height:15px;display:inline-block;background-color:<%=segments[i].fillColor%>\"> </span>_x000D_

I think the easiest (and maybe most elegant) solution here is to leverage the fact that you can set default
to a callable. So, to get around admin's special handling of auto_now, you can just declare the field like so:
from django.utils import timezone
date_field = models.DateField(default=timezone.now)
It's important that you don't use timezone.now()
as the default value wouldn't update (i.e., default gets set only when the code is loaded). If you find yourself doing this a lot, you could create a custom field. However, this is pretty DRY already I think.
$Group
is an object, but you will actually need to check if $Group.samaccountname.StartsWith("string")
.
Change $Group.StartsWith("S_G_")
to $Group.samaccountname.StartsWith("S_G_")
.

There's a static method in ToolStripRenderer
class, named CreateDisabledImage
.
Its usage is as simple as:
Bitmap c = new Bitmap("filename");
Image d = ToolStripRenderer.CreateDisabledImage(c);
It uses a little bit different matrix than the one in the accepted answer and additionally multiplies it by a transparency of value 0.7, so the effect is slightly different than just grayscale, but if you want to just get your image grayed, it's the simplest and best solution.
I would like to add another way of changing a character in a string.
>>> text = '~~~~~~~~~~~'
>>> text = text[:1] + (text[1:].replace(text[0], '+', 1))
'~+~~~~~~~~~'
How faster it is when compared to turning the string into list and replacing the ith value then joining again?.
List approach
>>> timeit.timeit("text = '~~~~~~~~~~~'; s = list(text); s[1] = '+'; ''.join(s)", number=1000000)

isn't a standard function. Try snprintf
instead.
char str[LEN];
snprintf(str, LEN, "%d", 42);
Based on what Janek answered, this worked for me (Linux):
from selenium import webdriver
options = webdriver.ChromeOptions()
options.add_argument("--start-maximized")
driver = webdriver.Chrome(chrome_options=options)
You can use the set() function to convert an iterable into a set, and then use standard set update operator (|=) to add the unique values from your new set into the existing one.
>>> a = { 1, 2, 3 }
>>> b = ( 3, 4, 5 )
>>> a |= set(b)
>>> a
set([1, 2, 3, 4, 5])
I had this issue after VS mac updation. iOS sdk was updated. I was referring the ios dll in project folder. The version number in the hintpath
was changed.
Earlier:
<Reference Include="Xamarin.iOS">
<HintPath>..\..\..\..\..\..\..\..\Library\Frameworks\Xamarin.iOS.framework\Versions\13.18.2.1\lib\mono\Xamarin.iOS\Xamarin.iOS.dll</HintPath>
</Reference>
<Reference Include="Xamarin.iOS">
<HintPath>..\..\..\..\..\..\..\Library\Frameworks\Xamarin.iOS.framework\Versions\13.18.1.31\lib\mono\Xamarin.iOS\Xamarin.iOS.dll</HintPath>
</Reference>
<Reference Include="Xamarin.iOS"> <HintPath>..\..\..\..\..\..\..\Library\Frameworks\Xamarin.iOS.framework\Versions\13.18.3.2\lib\mono\Xamarin.iOS\Xamarin.iOS.dll</HintPath>
</Reference>
I referred to the numbers in the previous commit and changed only the numbers in project folder, did nothing in android,ios folders. Worked for me!!!
Now:
<Reference Include="Xamarin.iOS">
<HintPath>..\..\..\..\..\..\..\..\Library\Frameworks\Xamarin.iOS.framework\Versions\13.20.2.2\lib\mono\Xamarin.iOS\Xamarin.iOS.dll</HintPath>
</Reference>
i also recommend thinking this thru and then choosing to store images in your file system rather than the DB .. see here: Storing Images in DB - Yea or Nay?
Inline SVG can be used in IE 10 and 11 and Edge 12.
I've created a project called gray which includes a polyfill for these browsers. The polyfill switches out <img>
tags with inline SVG: https://github.com/karlhorky/gray
To implement, the short version is to download the jQuery plugin at the GitHub link above and add after jQuery at the end of your body:
<script src="/js/jquery.gray.min.js"></script>
Then every image with the class grayscale
will appear as gray.
<img src="/img/color.jpg" class="grayscale">
You can see a demo too if you like.
The macros defined in <inttypes.h>
are the most correct way to print values of types uint32_t
, uint16_t
, and so forth -- but they're not the only way.
Personally, I find those macros difficult to remember and awkward to use. (Given the syntax of a printf
format string, that's probably unavoidable; I'm not claiming I could have come up with a better system.)
An alternative is to cast the values to a predefined type and use the format for that type.
Types int
and unsigned int
are guaranteed by the language to be at least 16 bits wide, and therefore to be able to hold any converted value of type int16_t
or uint16_t
, respectively. Similarly, long
and unsigned long
are at least 32 bits wide, and long long
and unsigned long long
are at least 64 bits wide.
For example, I might write your program like this (with a few additional tweaks):
#include <stdio.h>
#include <stdint.h>
#include <netinet/in.h>
int main(void)
{
uint32_t a=12, a1;
uint16_t b=1, b1;
a1 = htonl(a);
printf("%lu---------%lu\n", (unsigned long)a, (unsigned long)a1);
b1 = htons(b);
printf("%u-----%u\n", (unsigned)b, (unsigned)b1);
return 0;
}
One advantage of this approach is that it can work even with pre-C99 implementations that don't support <inttypes.h>
. Such an implementation most likely wouldn't have <stdint.h>
either, but the technique is useful for other integer types.
The actual problem is with your
showList function.
There is an extra ')'
after 'visible'.
Remove that and it will work fine.
function showList()
{
if (document.getElementById("favSports").style.visibility == "hidden")
{
// document.getElementById("favSports").style.visibility = "visible");
// your code
document.getElementById("favSports").style.visibility = "visible";
// corrected code
}
}
I had the same error message in Eclipse 3.4.1, SUN JVM1.6.0_07 connected to Tomcat 6.0 (running in debug-mode on a different machine, Sun JVM1.6.0_16, the debug connection did work correctly).
Window --> Preferences --> Java --> Compiler --> Classfile Generation: "add line number attributes to generated class file" was checked. I did a clean, recompile. I did uncheck it, recompile, check it, recompile. I made sure the project did use the global settings. Still the same message.
I switched to ant build, using
<javac srcdir="./src/java" destdir="./bin" debug="true">
Still, same message.
I didn't find out what caused this message and why it wouldn't go away. Though it seemed to have something to do with the running Tomcat debug session: when disconnected, recompiling solves the issue. But on connecting the debugger to Tomcat or on setting new breakpoints during a connected debug session, it appeared again.
However, it turned out the message was wrong: I was indeed able to debug and set breakpoints, both before and during debugging (javap -l did show line numbers, too). So just ignore it :)

I think you are wrapping your exception in another exception (which isn't in your code above). If you try out this code:
public static void main(String[] args) {
try {
throw new RuntimeException("Cannot move file");
} catch (Exception ex) {
JOptionPane.showMessageDialog(null, "Error: " + ex.getMessage());
}
}
...you will see a popup that says exactly what you want.
However, to solve your problem (the wrapped exception) you need get to the "root" exception with the "correct" message. To do this you need to create a own recursive method getRootCause
:
public static void main(String[] args) {
try {
throw new Exception(new RuntimeException("Cannot move file"));
} catch (Exception ex) {
JOptionPane.showMessageDialog(null,
"Error: " + getRootCause(ex).getMessage());
}
}
public static Throwable getRootCause(Throwable throwable) {
if (throwable.getCause() != null)
return getRootCause(throwable.getCause());
return throwable;
}
Note: Unwrapping exceptions like this however, sort of breaks the abstractions. I encourage you to find out why the exception is wrapped and ask yourself if it makes sense.
As what has already been mentioned by others, what behind the mystery is Branch Predictor.
I'm not trying to add something but explaining the concept in another way. There is a concise introduction on the wiki which contains text and diagram. I do like the explanation below which uses a diagram to elaborate the Branch Predictor intuitively.
In computer architecture, a branch predictor is a digital circuit that tries to guess which way a branch (e.g. an if-then-else structure) will go before this is known for sure. The purpose of the branch predictor is to improve the flow in the instruction pipeline. Branch predictors play a critical role in achieving high effective performance in many modern pipelined microprocessor architectures such as x86.
Two-way branching is usually implemented with a conditional jump instruction. A conditional jump can either be "not taken" and continue execution with the first branch of code which follows immediately after the conditional jump, or it can be "taken" and jump to a different place in program memory where the second branch of code is stored. It is not known for certain whether a conditional jump will be taken or not taken until the condition has been calculated and the conditional jump has passed the execution stage in the instruction pipeline (see fig. 1).
Based on the described scenario, I have written an animation demo to show how instructions are executed in a pipeline in different situations.
Without branch prediction, the processor would have to wait until the conditional jump instruction has passed the execute stage before the next instruction can enter the fetch stage in the pipeline.
The example contains three instructions and the first one is a conditional jump instruction. The latter two instructions can go into the pipeline until the conditional jump instruction is executed.
It will take 9 clock cycles for 3 instructions to be completed.
It will take 7 clock cycles for 3 instructions to be completed.
It will take 9 clock cycles for 3 instructions to be completed.
The time that is wasted in case of a branch misprediction is equal to the number of stages in the pipeline from the fetch stage to the execute stage. Modern microprocessors tend to have quite long pipelines so that the misprediction delay is between 10 and 20 clock cycles. As a result, making a pipeline longer increases the need for a more advanced branch predictor.
As you can see, it seems we don't have a reason not to use Branch Predictor.
It's quite a simple demo that clarifies the very basic part of Branch Predictor. If those gifs are annoying, please feel free to remove them from the answer and visitors can also get the live demo source code from BranchPredictorDemo
If I understand correctly, you want flex-2-child to fill the height and width of its parent, so that the red area is fully covered by the green?
If so, you just need to set flex-2 to use Flexbox:
.flex-2 {
display: flex;
}
Then tell flex-2-child to become flexible:
.flex-2-child {
flex: 1;
}
See http://jsfiddle.net/2ZDuE/10/
The reason is that flex-2-child is not a Flexbox item, but its parent is.
It should work fine, are you wrapping the code in a $(document).ready()
call? If not use that or use live
i.e.
$('#fileupload1').live('change', function(){
alert("hola");
});
Here is a jsFiddle of this working against jQuery 1.4.4
If the pods are named meaningfully one could use simple Plain Old Bash:
keyword=nodejs
command="cat <("
for line in $(kubectl get pods | \
grep $keyword | grep Running | awk '{print $1}'); do
command="$command (kubectl logs --tail=2 -f $line &) && "
done
command="$command echo)"
eval $command
Explanation: Loop through running pods with name containing "nodejs". Tail the log for each of them in parallel (single ampersand runs in background) ensuring that if any of the pods fail the whole command exits (double ampersand). Cat the streams from each of the tail commands into a unique stream. Eval is needed to run this dynamically built command.
The above solutions must work. However you can try this one:
OnClientClick="return SomeMethod();return false;"
and remove return statement from the method.
If you are running under a flavor of Unix
:0,$!tr "[A-Z]" "[a-z]"
It's the same as adding any other external script or stylesheet. All you have to do is focus on giving the correct path and rel and type.
Note: When my favicon image was in the assets folder, it was not displaying the favicon. So I copied the image to the same folder as of my index.html and it worked perfectly as it should.
<head>
<link rel="shortcut icon" type="image/png/ico" href="/favicon.png" />
<title>SITE NAME</title>
</head>
It worked for me. Hope it works for you too.
I really like StartExplorer but it is a contextual launcher rather than in - IDE shell so not sure if that is what you want
I found this most useful:

CURLOPT_CONNECTTIMEOUT
- The number of seconds to wait while trying to connect. Use 0 to wait indefinitely.
CURLOPT_TIMEOUT
- The maximum number of seconds to allow cURL functions to execute.
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 0);
curl_setopt($ch, CURLOPT_TIMEOUT, 400); //timeout in seconds
also don't forget to enlarge time execution of php script self:
set_time_limit(0);// to infinity for example
You could use the .NET library to do the same thing which i believe is more straightforward.
string ConnectionString = "Provider=Microsoft.ACE.OLEDB.12.0; data source={path of your excel file}; Extended Properties=Excel 12.0;";
OleDbConnection objConn = null;
System.Data.DataTable dt = null;
//Create connection object by using the preceding connection string.
objConn = new OleDbConnection(connString);
objConn.Open();
//Get the data table containg the schema guid.
dt = objConn.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, null);
string sql = string.Format("select * from [{0}$]", sheetName);
var adapter = new System.Data.OleDb.OleDbDataAdapter(sql, ConnectionString);
var ds = new System.Data.DataSet();
string tableName = sheetName;
adapter.Fill(ds, tableName);
System.Data.DataTable data = ds.Tables[tableName];
After you have your data in the datatable you can access them as you would normally do with a DataTable class.
document.getElementsByName("name")
will get several elements called by same name .
document.getElementsByName("name")[Number]
will get one of them.
document.getElementsByName("name")[Number].value
will get the value of paticular element.
The key of this question is this:
The name of elements is not unique, it is usually used for several input elements in the form.
On the other hand, the id of the element is unique, which is the only definition for a particular element in a html file.
The skinny is that a CPU loads data from memory addresses, stores data to memory addresses, and execute instructions sequentially out of memory addresses, with some conditional jumps in the sequence of instructions processed. Each of these three categories of instructions involves computing an address to a memory cell to be used in the machine instruction. Because machine instructions are of a variable length depending on the particular instruction involved, and because we string a variable length of them together as we build our machine code, there is a two step process involved in calculating and building any addresses.
First we laying out the allocation of memory as best we can before we can know what exactly goes in each cell. We figure out the bytes, or words, or whatever that form the instructions and literals and any data. We just start allocating memory and building the values that will create the program as we go, and note down anyplace we need to go back and fix an address. In that place we put a dummy to just pad the location so we can continue to calculate memory size. For example our first machine code might take one cell. The next machine code might take 3 cells, involving one machine code cell and two address cells. Now our address pointer is 4. We know what goes in the machine cell, which is the op code, but we have to wait to calculate what goes in the address cells till we know where that data will be located, i.e. what will be the machine address of that data.
If there were just one source file a compiler could theoretically produce fully executable machine code without a linker. In a two pass process it could calculate all of the actual addresses to all of the data cells referenced by any machine load or store instructions. And it could calculate all of the absolute addresses referenced by any absolute jump instructions. This is how simpler compilers, like the one in Forth work, with no linker.
A linker is something that allows blocks of code to be compiled separately. This can speed up the overall process of building code, and allows some flexibility with how the blocks are later used, in other words they can be relocated in memory, for example adding 1000 to every address to scoot the block up by 1000 address cells.
So what the compiler outputs is rough machine code that is not yet fully built, but is laid out so we know the size of everything, in other words so we can start to calculate where all of the absolute addresses will be located. the compiler also outputs a list of symbols which are name/address pairs. The symbols relate a memory offset in the machine code in the module with a name. The offset being the absolute distance to the memory location of the symbol in the module.
That's where we get to the linker. The linker first slaps all of these blocks of machine code together end to end and notes down where each one starts. Then it calculates the addresses to be fixed by adding together the relative offset within a module and the absolute position of the module in the bigger layout.
Obviously I've oversimplified this so you can try to grasp it, and I have deliberately not used the jargon of object files, symbol tables, etc. which to me is part of the confusion.
It is only possible to do this cross domain if you have access to implement JS on both domains. If you have that, then here is a little library that solves all the problems with sizing iFrames to their contained content.
https://github.com/davidjbradshaw/iframe-resizer
It deals with the cross domain issue by using the post-message API, and also detects changes to the content of the iFrame in a few different ways.
Works in all modern browsers and IE8 upwards.
