OpenSUSE :: Set RxtxSerial - Java App Has Access To A Serial Port (via SiLabs CP210x Driver, Port /dev/ttyUSB0)
May 10, 2010I'm trying to set rxtxSerial to work so a Java app has access to a serial port (via SiLabs CP210x driver, port /dev/ttyUSB0). When I use update-alternatives --config java, there are 3 alternatives which provide `java'. I have tried openJDK and Sun. Both fail but with completely different messages.

Programming :: Easy Way Into Stereoscopic 3D
Nov 22, 2010I wanna get into the world of stereoscopic 3D and I was wondering are there any easy and straightforward solutions. Do I need specific hardware to view the results of my work? I heard that there are screens with which you don't need goggles but that there are problems with that too..
I might start doing something like 3 dimensional charts for example that I could actually see in 3D. I would definitely stay away from modeling characters like in 3D shooters.
Debian Configuration :: Cannot Open Java Socket - Port (9955) Closed
Feb 26, 2010I have a java application that I wrote recently. It runs off port 9955. The application runs great on my mac server. When I installed it on my linux box i cant get to it from outside the box. A port scan shows the port as closed. I flushed my iptables, did not help. I can telnet into the app locally, from the server and it works great. I cannot telnet from outside the server. I have a reference to the application in /etc/services as a tcp port (which it is).
netstat shows it as listening
netstat --listen
tcp6 0 0 [::]: SimpleSocketTest [::]:* LISTEN
netstat -anp | grep 9955
tcp6 0 0 ::: 9955 :::* LISTEN 1484/java

Mar 28, 2011Is it possible to swap a client ip and port ? This is what I am trying to do. Let say you have Comp1 and Comp2 And you have Server between them.

Jun 1, 2010I have been working on writing a small rs232 driver like minicom for months. I am almost there, I have the interrupt service routine running, I can read() ok. However when I write(), it returns the number of characters written, 1, but nothing is actually written out the port. I researched termios, and they say that serial port programming is really messy in linux/unix.
I am probably not setting up the port parameters correctly, or my write() function is not doing what it is supposed to. As I said, write() is returning successful. Other comm programs run ok (picocom & gtkterm) on my hardware. I am running knoppix/debian on an ancient computer. I saw other guys using slackware.

Programming :: Edit Sshd_conf Files To Change The "#Port 22" To "Port 22" From A Script?
Feb 4, 2011i am trying to edit sshd_conf files to change the "#Port 22" to "Port 22" from a script.
I have tried this many different ways.
sshs1='s/#Port 22/Port 22/g'
sed $sshs1 /home/l/Desktop/test
the reason i have it as a string in this instance is because $sshs1 gets a variable, but im not working on that right yet. I've tried changing the ' to ` and ". this is what i get:
sed: -e expression #1, char 7: unterminated `s' command
sed: -e expression #1, char 8: extra characters after command
sed: -e expression #1, char 8: extra characters after command
"
sed: -e expression #1, char 7: unterminated `s' command
i know it may have to do with my regex, but i cant seem to find a decent tut.

View 2 Replies View RelatedProgramming :: Stick With Java?
May 12, 2011Situation: this semester I took an class called Introduction to Software Design with Java.It was my first intro to programming. The class had a very odd structure:1. The text was extremely high level. The first few chapters were all about object oriented programming, how objects interact, all about specification, etc (without ever talking about implementation).2. The lecture simply followed (directly) the text. And as a result was rather uninteresting.3. While highly theoretical (in that it was very high level approach), we never talked about how the computer was dealing with the information, etc.as all very "hand waving/magic" approach.
Okay so enough of the complaints:Question: This summer I'd like to dive a bit more into a language mainly out of frustration and lack of a good book. I'm thinking perhaps a lower level language.1. Would C++ be a good second language? Or should I give Java more time?2. If I am going to go with something else, is C++ sufficiently different, or should I go with C

Programming :: How To Set Up Global Class In JAVA?
May 10, 2011I've had to do some code in java, a language I'm very much unfamiliarly with so please excuse my incorrect use of terms. The basic outline of my problem is I create a class object as a local within a swing button function it works fine. If I create it as a global ( with I think I need to do ) within main, then prototype it with the other swing objects at the bottom of the file when it is called it causes a host of problems. I think the easiest way is to show it.

Feb 26, 2011I'm currently writing a program which will eventually send two 2d arrays to another machine using UDP, and then back again.
To do this I'm converting to a byte array which as far as I'm aware is the only way possible. I'm sure the problem is on the receiving program which receives like this:
Code:
DatagramSocket socket = new DatagramSocket(2000);
DatagramPacket packet = new DatagramPacket(new byte[5000] , 5000);
socket.receive(packet);
ByteArrayInputStream bin = new ByteArrayInputStream(packet.getData());
