Javascript onClick event in all cells
I'm learning JavaScript and I've not that much experience. But I'm making
a HTML table and I want to add in every table cell (<td>) a onClick event.
<table id="1">
<tr>
<td onClick="tes()">1</td><td onClick="tes()">2</td>
</tr>
<tr>
<td onClick="tes()">3</td><td onClick="tes()">4</td>
</tr>
</table>
Is there another way to do this event in every cell?

Oh no. Upgrade interupted. Please help
Oh no. Upgrade interupted. Please help
I have decided to upgrade my Ubuntu 12.04 to 12.10. I had about 4.1GB
space left on /. NOt until the last minute during the install phase did
the upgrade manager ask me to make space on my drive. I started the
software manager and now I can't get out of it back to continuing the
upgrade. It keeps on asking me to repair the package catalogue, and has no
x bar or button to close it, nor can I alt-tab to the updater window. I am
stuck half way through an upgrade and can't get out. I have been a fan of
ubuntu for years but after today I fear I have lost confidence.... Please
someone help. How can they write software that allows this to happen.
Should they be making sure there is adequate disk space before the
upgrade.

Rollover to be loaded with the index page and disappears when iframe is loaded with content from a link
Rollover to be loaded with the index page and disappears when iframe is
loaded with content from a link
I'm having a small issue with iframe and rollover image.
What I want to achieve is when I load this index site it should display a
rollover image(or a slider later on once I know how to do it) in the
middle of the page. I have placed an iframe in the middle of this index
page. This iframe is going to be the target of the horizontal menubar...
How do I make them to co-exist, rollover to be loaded by default and
disappears once the iframe is loaded with content from a link?
I have tried to place a rollover inside the iframe and also now inside the
same div of the iframeBut the result is not good since the rollover image
is not disappearing when loading a link to the iframe:

TableView not showing
TableView not showing
I have a very big FXML file that I designed on JavaFx SceneBuilder. When I
try adding a TableView now, the TableView only shows in the JavaFx
SceneBuilder and SceneBuilder's "Preview in Window", but not when I run
the project from netbeans.
Everything else in the scene shows perfectly.
Has anyone ever experienced this problem during development? How do I make
the TableView show when I run the project?
Thank you all in advance.

Slider Puzzle problems
Slider Puzzle problems
This is my slider puzzle game. So far it can only do 3x3 games. When I try
and pass the variables l and w (length and width) of the board it doesn't
work. It only works when i set the variables ROWS and COLS as finals. When
I try and change it I get errors. I'm not sure what to do, any help would
be appreciated.
Currently the user can input values that can't do anything at the moment.
When the game is started, a 3x3 board is generated. The user can restart
the game with a different scrambled board but the buttons that solve the
board and the buttons that reset the board to the original state do not
work yet.

Wait for the end of an asynchronous Javascript function to retrieve a result (Deferred ?)
Wait for the end of an asynchronous Javascript function to retrieve a
result (Deferred ?)
Ok guys, I know this topic has already been discussed multiple times, but
I can't find an answer to solve my problem.
So I'm trying to do a simple think : I'm creating a string, like :
distance is : " + CalculateDistance(position); The wanted result is
something like distance is 5kms (8min).
CalculateDistance(position) is a function calling a Google maps API called
DistanceMatrix to calculate distance between two points. The API is
documented here, and the given sample perfectly works. I adapted it like
this :
function CalculateDistance(position)
{
var service = new google.maps.DistanceMatrixService();
var destination = new google.maps.LatLng(/* some lat/lng */);
service.getDistanceMatrix(
{
origins: [position],
destinations: [destination],
travelMode: google.maps.TravelMode.DRIVING,
unitSystem: google.maps.UnitSystem.METRIC,
avoidHighways: false,
avoidTolls: false
}, callback);
}
function callback(response, status) {
if (status == google.maps.DistanceMatrixStatus.OK)
{
var origins = response.originAddresses;
var destinations = response.destinationAddresses;
var results = response.rows[0].elements;
distanceMatrixResult = results[0].distance.text + " ( " +
results[0].duration.text + " min)";
}
Oh, by the way, distanceMatrixResult is a global variable. In fact, I just
need to get the content of results[0].distance.text (and when I print it
in the console in callback(), the value is OK) and then concatenate the
value with "Distance is". If someone have a smarter solution, it is
welcomed !
The API call is asynchronous, and in my case, distanceMatrixResult is
always empty in the result string. But when I log its value in the
console, distanceMatrixResult value became the good one AFTER the string
was created.
All I want to write is :
• Call CalculateDistance (which call callback asynchronously)
• When callback is ended, concatenate the string with the
distanceMatrixResult value.
I tried some Deferred, like $.done() and $.when().then() but I can't
success...
Can someone help me ?
Thank you !

Proof of closed sets being invariant under inverse images by continuous functions
Proof of closed sets being invariant under inverse images by continuous
functions
I am studying the below portion of the proof, part of which confuses me:
Suppose that $f: A \to \mathbb{R}^m$ is continuous. Also, suppose that $E$
is a closed subset of $\mathbb{R}^m$. Let $B = f^{-1} (E)$. Now, we show
that $\overline{B} = B$. Clearly, $f(B) = f(f^{-1}(E)) \subseteq E$.
Further, that $A$ is closed implies that the closure of any subset C of A
is contained in A $ \\ $
Thus, if $x \in \overline{B}$, then \begin{equation} f(x) \in
f(\overline{B}) \subset \overline{f(B)} \subset \overline{E} = E \nonumber
\end{equation} Thus, $x \in f^{-1} (E) = B$. Therefore, $\overline{B}
\subset B$, and by Theorem 8.32 (i), $B \subset \overline{B}$. Thus $B =
\overline{B}$. Thus, $B$ is closed.
My question is, how do we know that $f(\overline{B}) \subset
\overline{f(B)}$?

DNS Server, DHCP Client and Server works fine, but request time out occurs when using MikroTik as an access point for a modem
DNS Server, DHCP Client and Server works fine, but request time out occurs
when using MikroTik as an access point for a modem
I use 2 Mikrotik wireless router, the first one is connected to modem and
it works perfectly (SSID: server-one (hidden)).
Second router ID:
ether1: 192.168.1.1
wlan1: dhcp-client
wlan2: 192.168.2.1
SSID: skywifi
Then, i tried to configure the second router. I set wlan1 to connect to
server-one, as a station and dhcp client and received 192.168.50.124 as
its IP, 192.168.50.254 as its gateway.
I set wlan2 as an ap-bridge, and set it as dhcp server. Then I create a
static route to 0.0.0.0/0 through 192.168.50.254.
Connection OK, DNS to device connecting skywifi works perfectly, i can
nslookup google.com. The problem is, when i tried to ping google.com, it
always give request time out reply. (Note that I also tried to ping
another host too (Wikipedia,Yahoo, etc). The result is also request time
out.
Any idea why this things happened? Thanks,

Fire a javascript function after jquery autosuggest selection made
Fire a javascript function after jquery autosuggest selection made
I have the jQuery autosuggest working. What i'd like to do though is after
the data is selected from the autosuggest, to be able to fire off a
javascript function. So the user selects the name John Smith and some
other info gets populated with ajax. I have the ajax working, I have the
autosuggest working but can't figure out how to get the autosuggest to
fire off the ajax.
I've tried putting a call in the select portion of the autosuggest.. that
didn't work. was almost as if it was getting ignored. Anyway.. I've looked
around and can't find the answer.
thanks for any help shannon

How to implement double indexing in a 2D sparse scipy matrix?
How to implement double indexing in a 2D sparse scipy matrix?
Suppose I have a 2D sparse matrix M representing the results of 2-on-2
basketball matches. I want to use address the elements of the matrix using
double-indexing : Element M[i,j][k,l] will represent the score of the game
played by a team of players i and j against team k and l. Thus, each
column/row is specified by two numbers instead of one. Note that this is
not a 4D matrix. I'm looking for a way to do this with a sparse SciPy
matrix in order to be able to perform various matrix-related calculations
(eigenvalues/vectors, etc).

I am storing all fields in the database and have that working properly
using http://medoo.in/. How do I go about creating a PHP script to send a
recurring email based on the Service Date and the selected Reminder (every
30 days, 60 days, semianually, annually)? I was thinking of using PHP
mailer to send the actual emails and running a daily cron job.

TreeView binding from XML by ID
TreeView binding from XML by ID
I'm using WPF.(MVVM pattern) I want to make hierarchical tree using
TreeView. Data from XML. But XML structure is not hierarchical actually.
Nodes binds by ID. XML looks like the following:
<root>
<node>
<Id>1</Id>
<ParentId>-1</ParentId>
<Name>ROOT</Name>
</node>
<node>
<Id>2</Id>
<ParentId>1</ParentId>
<Name>NODE</Name>
</node>
</root>
What should i use to do this? It will be great if you show me any simple
example.
And the second question. How can i get nodes dinamically? That is when i
run the application only root is loading.
Thanks in advance.

Use Python's `timeit` from a program but functioning the same way as the command line?
Use Python's `timeit` from a program but functioning the same way as the
command line?
For instance, documentation says:
Note however that timeit will automatically determine the number of
repetitions only when the command-line interface is used.
Is there a way to call it from within a Python script and have the number
of repetitions be determined automatically, with only the shortest number
returned?

Using column name when using SqlDataReader.IsDBNull
Using column name when using SqlDataReader.IsDBNull
Hello I have got this code which reads data from SQL DB.
I don't know how should I edit it so I can use original column name and
not column index.
string query = "SELECT * FROM zajezd WHERE event='" +
thisrow+ "' AND year='" + klientClass.Year() + "'";
SqlCommand cmd= new SqlCommand(query, spojeni);
spojeni.Open();
SqlDataReader read= cmd.ExecuteReader();
if (read.Read())
{
maskedTextBox2.Text = read.IsDBNull(24) ? string.Empty :
read.GetDateTime(24).ToString("MM/dd/yyyy");
Thanks in advance.

PHP & SQL - get results from db where date is today
PHP & SQL - get results from db where date is today
i'm trying to do the following thing: In my Database, I have rows with
time in each one (using time() function). For example: 1380300397. Now,
I'd like to build a query that gets the rows from the current day. I've
tried this query with no success:
SELECT `id`,DATE_FORMAT(`time`, '%Y-%m-%d') FROM `facts`
WHERE `app` = 1 AND DATE(`time`) = CURDATE()
What am I doing wrong? Thanks!

Data Source SQL Command from Variable using default value instead of updated value
Data Source SQL Command from Variable using default value instead of
updated value
I have four dynamically assigned variables in my package. Each one is
populated using a query similar to this:
select 'SELECT * FROM SHARE_DM.MDM_ORG_CLASSIFICATIONS WHERE LAST_UPD_DATE
>= '''
+ (select convert(nvarchar(50), coalesce(max(last_upd_date),
cast('1/1/1900' as datetime)), 106) from MDM_ORG_CLASSIFICATIONS)
+ '''' sql
The default queries are defined like this:
SELECT * FROM SHARE_DM.MDM_ORG_CLASSIFICATIONS WHERE LAST_UPD_DATE >= '01
Jan 1900'
(I'm building the sql like this because I'm using Oracle data connections
and the parameter parsing doesn't work properly, where this technique has
worked before)
The output sql comes out like this:
SELECT * FROM SHARE_DM.MDM_ORG_CLASSIFICATIONS WHERE LAST_UPD_DATE >= '26
Sep 2013'
I have validated that my variables are being updated using message boxes
in script components. When I run the queries manually against Oracle, I
get very small result sets, as expected. However, when I run the package,
I get full result sets as if the default value of 1/1/1900 was being used
instead of the updated variable.
Each variable is set to EvaluateAsExpression False.
Comparing the operation in this package vs. a different package where I do
the same kind of operation, I'm not seeing any obvious differences -
except for one thing - in the other package I list each column in the
select statement, whereas in here I use select *.
Why isn't my OLE DB Source updating with the updated SQL from the variable?
Edit: Thinking maybe the select * was the issue, I updated one of them to
use explicit column names. No change.

Calling C++ method in QML Error "Cannot Call Method 'x' of null"
I'm having some difficuly calling a method from a C++ class in QML. I keep
getting a "Cannot call method 'x' of null" error. Here is my code:
QML:

anchors.leftMargin: 10
anchors.top: m_OutputRow.bottom
anchors.topMargin: 10
onClicked: m_OutputText.text = m_Model.getPluralization();
}
}
MainWindowModel.h

}
Any help will be appreciated, thanks.

keep the first part and delete the rest on a specified line using sed
keep the first part and delete the rest on a specified line using sed
I know a line number in a file, wherein I want to keep the first word and
delete the rest till the end of the line. How do I do this using sed ? So
lets say, I want to go to line no 10 in a file, which looks like this -
goodword "blah blah"\
and what i want is
goodword
I have tried this - sed 's/([a-z])./\1/'
But this does it on all the lines in a file. I want it only on one
specified line.

"This version of JustMock has expired!" after purchasing a license
"This version of JustMock has expired!" after purchasing a license
I recently purchased a license for Telerik JustMock. The Telerik Control
Panel shows JustMock under my list of Purchased products. When I attempt
to run my tests in Visual Studio's Test Explorer with the JustMock Visual
Studio extension enabled I receive an exception saying:
Telerik.JustMockExpiredException : This version of JustMock has expired!
I have uninstalled all the Telerik Visual Studio extensions, uninstalled
everything Telerik via Windows Programs/Features, then re-installed the
control panel and then JustMock yet the problem persists. Of note, when I
re-installed the control panel it remembered my username/password so I'm
guessing there is a configuration file somewhere caching my information
incorrectly.
A possible root cause of this problem is that I was trialing JustMock
under my personal email address but it was purchased by my company and
assigned to my work email address. I am currently logging into the control
panel with my work address and see no other place to change that.

NullPointerException when trying to send a message to a Client Socket
NullPointerException when trying to send a message to a Client Socket
I have a ServerHandler class, which creates a new PrintWriter and stores
it into a PrintWriter array, The message gets sent by giving the
selectedId integer the ID number of the client that should receive the
message. When i call the SendMessage() method inside the ServerHandler
class it sends the message without a problem, but when i try to call the
SendMessage("some message") method from the class that contains the GUI it
gives me a NullPointerException.
The posljiSporocilo() is the actual SendMessage() because some methods are
in my language

Passing calculation result to JSP page
Passing calculation result to JSP page
Index.jsp takes two input number and after submit the request go to
Operation.java. It has a radio button to select Operation. Both inputs and
radio button are submitted to Operation.java.

Entity Framework 5, switch from code first to database first?
Entity Framework 5, switch from code first to database first?
I've already created a database using code first. It worked well. Many
changes have since been made to the database outside Visual Studio. So
many that any attempt at migration generates errors. So my question is, is
there a way to switch a solution from code first to database first?

Call function directly after constructor: new Object()->callFunction()
Call function directly after constructor: new Object()->callFunction()
As you might have seen in the title, my programming background is Java. In
Java you can do stuff like this
new Object().callSomeMethod();
without assigning the created Object to a variable, very useful and clear
coding if you only need this Object once.
Now in PHP i try to do the same
new Object()->callSomeMethod();
but here i get a 'Parse error: syntax error, unexpected '->'
(T_OBJECT_OPERATOR)'.
Is there a way to do this in PHP ?

Use custom powershell module in C#
Use custom powershell module in C#
I wrote fuction PowerShell module like that:
Function docConvert2{
param ([string]$sourceFile, [string]$sourceFilePath)
....
....
}
I've imported module successfuly
And i can use module in powershell cmdlet
When i try call function in c#, i got exception like that
The term 'docConvert2' is not recognized as the name of a cmdlet,
function, script file, or operable program. Check the spelling of the
name, or if a path was included, verify that the path is correct and try
again.
C# code
PowerShell pShell = PowerShell.Create();
pShell.AddCommand("docConvert2");
pShell.AddParameter("sourceFile", "'addendum no-3_PREP.doc'");
pShell.AddParameter("sourceFilePath", @"'D:\New\wordler'");
pShell.Invoke();
What is my mistake?
Thanks for advices.

show loading dialog for multiple ajax request
show loading dialog for multiple ajax request
I am making two ajax call asynchronously, on each call I am showing a
loading dialog box like this,
jQuery('#msg_writter').show();
on success of each request I will hide the loading dialog like this,
jQuery('#msg_writter').fadeOut(1000);
my html code for loading dialog:
<div id="msg_writter" class="msgWritter">
<img src="/images/loading.gif"/>
</div>
when the first request is done, the loading dialog gets disappear so
loading dialog is not showing for the second request.
How could I modify the code to show the loading dialog from the first
request till the success of last request.

Ajax - Lazy load random elements without repeating
Ajax - Lazy load random elements without repeating
I have a database of, lets say 10,000 records. I have a webpage where I
want to display each record in a list, in random order. Because there are
so many records, I want to initially load only 100 records on the page,
and as you get to the bottom of the page, another 100 is added via AJAX,
then as you scroll to the bottom, 100 more, etc...
The trick is that overall, I want the order of the displayed records to be
random, but also, they cannot repeat. So just doing an AJAX call to pull
in 100 random records isn't going to work since some of those records may
have already been displayed on the page.
Is there a certain trick to doing this?
I was thinking maybe keeping track of the record id's that have been
displayed already and sending this in the AJAX call and then fetch 100
random records who's ID's have not already been displayed... But I'm
afraid for a high traffic website, this would get pretty slow as you can't
cache that too easily, without recreating the same thing using cached
arrays.
What is the best approach to this?

Customer view for Team Foundation Service
Customer view for Team Foundation Service
My team recently migrated from onsite to the cloud Team Foundation Service
2012.
We had also maintained a separate SharePoint portal with extranet
capabilities to list projects/tasks etc. for external customers
Seeing that we're now online, I was wondering if there is a means to
restrict a view to PBIs/Certain properties of tasks [Time Elapsed, Time
Remaining] for certain accounts.
Alternatively, I recall seeing SSRS capabilities in the on site version.
Is there a means to configure reports (scheduled/manual) using the Team
Foundation Service?

Is there a way to determine if a parameter is a literal string?
Is there a way to determine if a parameter is a literal string?
My question is:
Is there a way to determine whether a parameter is a literal string or not?
template<class T>
bool IsLiteral(T arg)
{
// How to implement?
}
or
template<class T>
struct IsLiteral { enum { value = ??? }; };
So that we can write the following code:
char* p = "Hello";
assert(IsLiteral(p)); // fail.
assert(IsLiteral("Hello")); // never fail.
My question is:
Is there a way to determine whether a parameter is a literal string or not?
template<class T>
bool IsLiteral(T arg)
{
// How to implement?
}
or
template<class T>
struct IsLiteral { enum { value = ??? }; };
So that we can write the following code:
char* p = "Hello";
assert(IsLiteral(p)); // fail.
assert(IsLiteral("Hello")); // never fail.
CheckBox in C# Windows App
CheckBox in C# Windows App
I have 3 checkboxes and I am able to turn two of them off if one is
checked. But I want that if the 3rd one is checked then the first two
should be turned off. how can I do that?
This is what I am trying.
private void chkResFoodVeg_CheckedChanged(object sender, EventArgs e)
{
//disables the other checkbox if one is checked
this.chkResFoodNveg.Enabled = !this.chkResFoodVeg.Checked;
}
private void chkResFoodNveg_CheckedChanged(object sender, EventArgs e)
{
this.chkResFoodVeg.Enabled = !this.chkResFoodNveg.Checked;
}
private void chkResFoodBoth_CheckedChanged(object sender, EventArgs e)
{
this.chkResFoodBoth.Enabled = !this.chkResFoodNveg.Checked &&
!this.chkResFoodVeg.Checked;
}
The last part of code doesn't work. It should turn off the first two
checkboxes.
Thanks

Is there a way to control thread count, affinity and creation time in Intels Threading Building Blocks?
Is there a way to control thread count, affinity and creation time in
Intels Threading Building Blocks?
Currently I use Intels TBB to parallelize some work using
tbb::parallel_for. It seems that the amount of threads and the point in
time when they are started is controlled by TBB in the background. Looking
through the User Guide and Reference Documentation I could not find any
hint on whether there are any control options or modules. I would like to
be able to modify the amount of threads and, if possible, decide when the
thread pool is created.

Using non-ASCII characters in cmd batch file
Using non-ASCII characters in cmd batch file
I'm working on a .bat program and the program is written in Finnish. The
problem is that CMD doesn't know these "special" letters such as : Ä, Ö,
Å.
Is there a way to make those work? I'd also like it if the user could use
those letters too.

UICollectionView Cells and Rasterizing
UICollectionView Cells and Rasterizing
I recentlty discovered that by adding this before returning my collection
view cell improves scrolling animation performance (smoothness).
cell.layer.shouldRasterize = YES;
cell.layer.rasterizationScale = [UIScreen mainScreen].scale;
If my cell contains, multiple buttons do I need to rasterize those
individually, or will that be taken care of automatically?... or should I
ever bother?
I have added the buttons via Interface Builder.

substring dynamic number of characters
substring dynamic number of characters
I'm working with 2 sets of data that were merged together, but they're
inconsistent in their format. Some are 10 characters, all numbers. Others
may have a separator : at position 4. I need to substring the first 4
characters. But if the 4th character is a : substring only the first 3
characters.
Does mysql have an IF functionality to determine the number of characters
to substring based on the character in position 4?
select substring(id, 1 , 3/4) from table1

CSS navigation issues and image sound
CSS navigation issues and image sound
I'm currently working on a site which is very basic. and its has 2 issues.
I've uploaded my site. which is being edited until its fully working. The
intro page works fine which is the index. html page. Then second I click
on my sites menu bar for HOME it loads home. While on HOME I want to go to
INTRO. To see if the link works. instead loading intro page as it does
when I load site for first time. It loads the WEBHOST site page? Can
anyone pass on any clues as to why this happens.
Also my second question is when putting together my profiles page together
of the cast of the A-TEAM show. With images on left column underneath each
other running down page and text on right same way as pictures. I want
each image to be clicked on to play the sound. I don't want no in browser
players or anything else. just click image play sound. were do I put the
code and can how I make it work for the 5 images that need audio linked to
them?

Another class interacting with variables in main method
Another class interacting with variables in main method
I have a main method which creates a List<Long>. I then have another class
whose state is a List<Long> - the goal of this class is to take in the
main method's List<Long> as its state and do manipulations to it without
affecting the main method's List<Long>.
However the problem that I am facing is that this other class is impact
both its state (its private List<Long>) as well as the List<Long> in the
main method.
How do I adjust my code such that setTesting(...) is only able to
influence the state of its class?
public class Main {
public static void main(String[] args) {
final List<Long> mainlist = new ArrayList<Long>();
mainlist.add((long) 1);
mainlist.add((long) 2);
mainlist.add((long) 3);
Test testlist = new Test();
testlist.setTesting(mainlist);
System.out.println(testlist.getTesting());
testlist.removal((long) 1);
System.out.println(testlist.getTesting());
}
}

Unicode null and JSON
Unicode null and JSON
I have a JSON object that when serialized gets the null Unicode character.
(The character is coming from a database.) I can replace the character
through java but it seems slightly hackish to look for a specific
character to fix. So I'm wondering if there's a way I can do it by just
changing the encoding. It's currently being encoded using UTF-8. Any
thoughts?

`reg_date` int(11) NOT NULL DEFAULT '0',
`id` int(11) NOT NULL,
PRIMARY KEY (`abuse_id`),
KEY `reg_date` (`reg_date`)
) ENGINE=MyISAM DEFAULT CHARSET=latin1 COMMENT='Table with abuse reports'
AUTO_INCREMENT=2 ;
this table already exists in the database, but when i import an sql file
with phpmyadmin, the following error occurs
--
-- Dumping data for table `probid_abuses`
--
INSERT INTO `abuses` ( `abuse_id` , `user_id` , `abuser_username` ,
`comment` , `reg_date` , `auction_id` )
VALUES ( 1, 100020, 'artictundra', 'I placed a bid for it more than an
hour ago. It is still active. I thought I was supposed to get an email
after 15 minutes.', 1338052850, 108625 ) ;
#1062 - Duplicate entry '1' for key 'PRIMARY'
i thought because it already exists it won't attempt to create it, why is
it behaving as such?
Mysql LOAD DATA INFILE doesnt work properly
Mysql LOAD DATA INFILE doesnt work properly
This is my mysql query: LOAD DATA LOCAL INFILE 'E:\c.csv'
INTO TABLE messages
FIELDS TERMINATED BY ','
LINES TERMINATED BY '\r\n'
(idR, idS, nameS,message,readd);
and my .csv file: 7,998,mehman,hello,5 and 8,998,mehm,hello,5 2 rows
everything is fine except it writes 0 instead of 7 in the first row and
why there is no difference when changing \r\n to \n? thanks in advance!

How to use particular gem version on irb?
On my machine, I've following Selenium WebDriver versions:
selenium-webdriver (2.35.1, 2.35.0, 2.33.0, 2.32.1)
While executing selenium commands on irb, I want to use selenium-webdriver
2.35.0 All api related to Selenium Webdriver should use selenium-webdriver
2.35.0
How can I achieve this?
Something like require 'selenium-webdriver 2.35.0'? Please suggest solution.

Issues with running a bash with an RVM environment
Issues with running a bash with an RVM environment
I am using whiskey_disk in order to handle deployments. This isn't a
whiskey_disk issue, but what it does is run a post deploy script after it
finishes cloning from git into the project destination directory. The
script I'm trying to deploy is to invoke a bundle install and looks a
little something like this:
#!/bin/bash
# Load RVM into a shell session *as a function*
if [[ -s "$HOME/.rvm/scripts/rvm" ]] ; then
source "$HOME/.rvm/scripts/rvm"
elif [[ -s "/usr/local/rvm/scripts/rvm" ]] ; then
source "/usr/local/rvm/scripts/rvm"
else
printf "ERROR: An RVM installation was not found.\n"
fi
export
PATH=/home/ec2-user/.rvm/gems/ruby-2.0.0-p247/bin:/home/ec2-user/.rvm/gems/ruby-2.0.0-p247@global/bin:/home/ec2-user/.rvm/rubies/ruby-2.0.0-p247/bin:/home/ec2-user/.rvm/bin:/usr/local/bin:/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/sbin:/opt/aws/bin:/home/ec2-user/bin

That fails, and is not able to find bundle or rake, even though it's
clearly setup in my $PATH above:

Thought I initialized the environment above fine in the beginning of the
script and by additionally setting my PATH which you could see is seen
fine with an interactive shell:
[ec2-user@ip-1 ~]$ which bundle
~/.rvm/gems/ruby-2.0.0-p247@global/bin/bundle
[ec2-user@ip-1 ~]$ which rake
~/.rvm/gems/ruby-2.0.0-p247@global/bin/rake
Any suggestions on what else could be the issue?
