I can't figure out where exactly to go in order to write the Ruby code itself. I know that I can enter things line-by-line in Terminal (I'm on a Mac), but I'd like to figure out how to start using something like Xdrive (Apple won't allow me to download Xrive because I have OS X 10.5, not 10.6).
What steps do I need to take in order to start writing code in a program like xDrive.
Thank you in advance.
I want to use the performance counter output in my program. How can I access the performance counter in code without using the perfmon.exe. I want to create my own performance counter app.
I would like to make a small program that scrapes information from a 3rd-party GWT-enabled website. Is it possible to somehow call this RPC directly? What would I need to reverse-engineer to do this (i.e. hopefully not the entire low-level protocol).
I am hoping I could somehow just call this from within my own server-side GWT or Servlet app.
Hello,
I'm about to develop some commercial software that will run on OSX and Linux. The program will be doing some heavy string manipulation, base64 encoding, zlib compression and may require http libraries in the future.
Does anyone have a suggestion?
Many thanks in advance,
Toby.
I'm a little confused about scope of variables, in ruby I wrote a test program:
class Test
attr_reader :tester
def initialize(data)
@tester = data
end
def getData
tester
end
end
puts Test.new(11).getData
now this works fine, the attr_reader, but my confusion is that since I've define attr_reader :tester then why can't I go tester = data rather then @tester = data, because when retrieving the data in getData I only have to write tester and not @tester
This is a very newbie question.
I want to know how to create a WEB APP to make Call ( using VOIP protocoll I think ).
What program languages do I have to learn ( client and server side ) ?
Communication ports:
Change a given class in an applet in that way, that browser-defined proxy-configuration files can be used for applet communication with serve(upload method). i.e browser communicate via port 8080 or via ssl(443) - applet should also communicate by this port automatically. In the given method port 80 is hardcoded.
-- please give some code or program for this..
Is there any plug-in that provides an integrated shell (i.e. command prompt) in Eclipse?
The console only seems to be for interaction with a running program.
I've found a reference to the plug-in Open extern but that opens an external command window, and I'd rather have it integrated with Eclipse.
I'm my program i'm loading a fairly large MutableDictionray and I would like to use a UIProgressBar. Does anyone have a suggestion of how to determine the loading time to make this work?
Thanks
I've done a lot of research on when it's correct to release things, but it's all confusing to me. I think sometimes the Leaks program is off. Anyway...
background is a UIImageView
background.image = [UIImage imageNamed:@"greenbackground.png"];
Do I have to release background? I never alloced it and it's not set as a property, so I'm thinking no.
In their dev site,AOL says the contacts api would coming soon from the year 2008-_-
but I can't find anything about it since then, and I find in window live add contacts site:
http://cid-7b76c1c8e1ade1ea.profile.live.com/connect/
They have a program to port contacts from AOL, that is this only for Microsoft. Is there another method to do this?
In my program I have a dataTable and I´d like to know if is there a column which name starts with abc.
For example I have a DataTable and its name is abcdef. I like to find this column using something like this:
DataTable.Columns.Constains(ColumnName.StartWith(abc))
Because I know only part of the column name, I cannot use a Contains method.
Is there any simple way how to do that?
Thanks a lot.
Is there a recognized, recommended, or standard form for representing the structure of JSON? E.g., my service returns a structure, effectively, represented as JSON. How do I describe what my service returns, such that another service can consume that JSON and program to its interface?
public class WrapperTest {
static {
print(10);
}
static void print(int x) {
System.out.println(x);
System.exit(0);
}
}
In the above code System.exit(0) is used to stop the program. What argument does that method take? Why do we gave it as 0. Can anyone explain the concept?Thanks.
Consider an object declared in a method:
public void foo() {
final Object obj = new Object();
// A long run job that consumes tons of memory and
// triggers garbage collection
}
Will obj be subject to garbage collection before foo() returns?
UPDATE:
Previously I thought obj is not subject to garbage collection until foo() returns.
However, today I find myself wrong.
I have spend several hours in fixing a bug and finally found the problem is caused by obj garbage collected!
Can anyone explain why this happens? And if I want obj to be pinned how to achieve it?
Here is the code that has problem.
public class Program
{
public static void main(String[] args) throws Exception {
String connectionString = "jdbc:mysql://<whatever>";
// I find wrap is gc-ed somewhere
SqlConnection wrap = new SqlConnection(connectionString);
Connection con = wrap.currentConnection();
Statement stmt = con.createStatement(ResultSet.TYPE_FORWARD_ONLY,
ResultSet.CONCUR_READ_ONLY);
stmt.setFetchSize(Integer.MIN_VALUE);
ResultSet rs = stmt.executeQuery("select instance_id, doc_id from
crawler_archive.documents");
while (rs.next()) {
int instanceID = rs.getInt(1);
int docID = rs.getInt(2);
if (docID % 1000 == 0) {
System.out.println(docID);
}
}
rs.close();
//wrap.close();
}
}
After running the Java program, it will print the following message before it crashes:
161000
161000

********************************

And here is the code of class SqlConnection:

public synchronized Connection currentConnection() throws SQLException {
if (this.connection == null || this.connection.isClosed()) {

}
return this.connection;
}

System.out.println("Finalizer CALLED!!");
System.out.println("********************************");
this.close();

Is there a definitive guide for special folders in windows? An internet search yielded just a few crumbs of information, e.g.
Wikipedia:Special Folders
Windows 7 Client Software Logo Program
What I'm looking for is an explanation of each folder, its intended purpose, usage scenarios and motivation for its existence (e.g. what does Local App settings provide for that App settings doesn't). A matrix/table of requirements/uses against folder would be handy I think.
I would like to dynamically allocate memory from an assembly
program that does not link against the standard C library.
Since brk(2) and sbrk(2) are unavailable on Mac OS X (10.6.2),
what are the alternatives?
(I'm guessing that it involves a Mach call, but there seems to
be little documentation around that)
I was experimenting with the Assembly and File version number. Though my program runs well from the IDE, but after creating a Setup file and installing the application crashes with InvalidDeploymentException.
What should I do to resolve the matter?
How do you take a commmand like this in PowerShell and split it across multiple lines:
&"C:\Program Files\IIS\Microsoft Web Deploy\msdeploy.exe" -verb:sync -source:contentPath="c:\workspace\xxx\master\Build\_PublishedWebsites\xxx.Web" -dest:contentPath="c:\websites\xxx\wwwroot\,computerName=192.168.1.1,username=administrator,password=xxx"

After watching the tier 1 video, where do I go to learn how to program in C#?
Is there an online video series?
Usually people say to "Read the Manual", but what is a manual these days? Do I just say "Help", "View Help" and start grokking?
I'm working with the source code for BonjourWeb using iOS 6 and Xcode 4.5.
BonjourWeb Source code for Xcode
In BonjourWebAppDelegate.m, the setting for showCancelButton:YES in the "applicationDidFinishLaunching: application:" method causes the program to crash when the Cancel button is clicked in the app's browser with the error: 2012-10-27 13:07:45.309 BonjourWeb[1762:c07] * Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '* +[NSNetService dictionaryFromTXTRecordData:]: cannot convert nil to a dictionary.'
How can I rectify this to work properly?
Thank you.

If I have a simple java program that processes lines of text from standard input, then I can run it with the following script:
@Echo off
java Test < file.txt
pause
exit
The script redirects lines of input from a separate file.
Is there a way that I can avoid having to use an extra file? Or is this the easiest way?
Thanks.
