Debian :: Writing Open Source Java Applications?
Feb 13, 2010
I always wanted to get into writing open source applications for debian. The only problem I ever saw was that I do not know C++ which seems to be the popular language to build applications. My expertise is Java and I think that java applications could run on debian just as good as C++ applications. What I do at work is write applications in java for unix systems so I think I porting my skills over to debian would not be a problem. I have not seen any applications in java on debian yet and thought people might have a problem with them. Is there any reason more java applications are not being written on debian? Also does anyone know of hand if there is any orphaned java application for debian. I had a look on this page but it is hard to know what language the application is written in. [URL]

Is there a good open source alternative to flash and/or java out there? I really don't want to support adobe and java irritates me because for some reason I can't install it without also installing firefox (why are they dependent?) so I'd like to try something else.

I am looking for an application that works in both linux and freebsd (windows would be a plus) that keeps a file tree in sync in the background like Dropbox does. I can no longer use Dropbox because it does not support FreeBSD (you might see a forum thread saying otherwise, but its fix is out of date). The application does not have to sync to a separate web server, I can host from my house, but it would be nice. A system tray icon to check on state would also be nice, but not required. The platforms that I really need are kubuntu 9.10 and FreeBSD 8.0.The simplest thing I could think of would be a script that had git update a repository with all my docs in it every minute or so, would this work?

Can anyone recommend a simple open source voip software in linux for pc-to-pc voice calls.
One requirement i that it should be simple with bare minimal functionality since I will be using as a part of a university project and so I don't want any additional features such as buddylist, GUI, etc.
Even a command line interface will also be fine since I am only interested to test different associated codecs/network characteristics.
The code should be simple with bare minimal libraries so that can be compiled easily.
I am aware of some open-source software such as WengoPhone but it seems that they have lot of associated features supporting different input devices with sophisticated GUI.
I require only PC-to-PC call functionality and I will be using within a LAN.

I'm looking for an open source system that can handle storing lots of images on tag basis, that permits me to find any image related to topics or type or post date. And also permits me to add notes. We have a lot of images and those images should be arranged according to topics in tagging manner as Google Mail do for classifying mails.

i cannot seem to find a proper way to make Java my default application to open .jar files. I just made a new Debian 8.3 install on my laptop HP Pavilion G6 and the default application for opening .jar files is the Archive Manager. But when i go to "Open with.." section on right-clicking the .jar file, i get no JRE or JDK option to choose. I just installed the openjdk 7. I can manually run them from the bash, but it would be much more convenient if i just double-clicked it. Here is what i get when i run several commands in the bash :
1) which java ->Code: Select all /usr/lib/jvm/java-7-openjdk-amd64/bin/java
2) java -version -> Code: Select alljava version "1.7.0_95"
OpenJDK Runtime Environment (IcedTea 2.6.4) (7u95-2.6.4-1~deb8u1)
OpenJDK 64-Bit Server VM (build 24.95-b01, mixed mode)
3) echo $PATH: Code: Select all/usr/lib/jvm/java-7-openjdk-amd64/bin:/usr/lib/jvm/java-1.7.0-openjdk-amd64/bin: /usr/local/ sbin:/usr/local/bin:/ usr/ sbin:/usr/bin:/ sbin:/bin
4) javac -version : Code: Select alljavac 1.7.0_95

I have a Broadcom BCM4312 LP-PHY in this machine. I was informed theres an open source driver for broadcom cards (brcm80211), but it doesn't seem to support this chipset. In the spirit of Debian, is there another driver available?

I 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

First of all I must say that I am new to Debian, but not newbie on Linux. I am the Arch Linux user too, and I managed to solve identical problem on Arch. So, as I want to try Debian I am facing the same problem again. Problem is that my GPU is overheating. I am using Ati open source driver. I installed it following the procedure on Debian wiki. On Arch I solved it with proprietary driver fglrx. I tried the same solution here but it doesn't work. So I am stuck with open source drivers.
The difference between Arch and Debian (fglrx vs. Ati open source) is 10 C degrees. Debian Ati open source is much hotter. And ofc I am facing the low battery life too, because of this. My laptop is using much higher energy consumption with open source driver (almost double). How can I check my energy consumption on Debian? I read about some xorg options. I tried it, but no effect. As I am on Debian testing I am using kernel 2.6.32. Does this kernel supports xorg video energy consumption options?

I'm running a Squeeze system on a PC with an ATI Radeon HD 4200 graphics card. Until recently I had been using the fglrx drivers without difficulty, but a recent upgrade removed fglrx - apparently this is because ATI has yet to release drivers for Xorg 1.7. So I've switched to the open source driver (radeon), but am not getting any 3D acceleration - hence can't run desktop effects in either kwin or compiz. When I run "glxinfo | grep OpenGL" I get the following:
OpenGL vendor string: Mesa Project
OpenGL renderer string: Software Rasterizer
OpenGL version string: 2.1 Mesa 7.6.1
OpenGL shading language version string: 1.20
OpenGL extensions:
It's the software rasterizer that is the problem, I gather. After Googling for similar problems encountered by others, I've installed firmware-linux and firmware-linux-nonfree, but to no effect. All fglrx-* packages are purged. Does anyone have any other thoughts? (I don't currently have an xorg.conf file in use.)

My questions is about switching graphics card on a Intel/AMD hybrid system using open source drivers (Envy 15 with HD4000 and AMD 7690M). I was waiting for an proprietary driver from AMD but apparently it will not be released in the near future and I need to use AMD chip for my 3D intense applications.

The ATI/AMD graphics hardware is:
01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Oland [Radeon HD 8570 / R7 240 OEM]
I installed "AMD/ATI Open Source Drivers" according to: "[URL] ....":
Reboot after "apt-get install firmware-linux-nonfree", the system automaticly reboot after grub, then went black screen forever (no tty1,tty2.., seems cannot booting). I reinstalled serveral times but same problem (having tried both cd/live dvd, debian8.1/8.2).
It seems that "firmware-linux-nonfree" is the cause, since debian crashed once firmware-linux-nonfree installed.
The problem went away by installing ATIProprietary driver("[URL] ....").
PC is dell 9020, i7

I've set up this new PC, the graphic card I picked is the ATI R7 260X, pretty good card with lots of core processors, high clock and 2GB memory. I'm now currently using the 14.4 catalyst drive, it works actually alright, though, there are some mishaps with this driver:
First my hdmi screen had scale down, leaving black borders around, even though the catalyst control said the correct native resolution, this turned out to be a underscan that fglrx does and I've finally managed to fix it. Other caveat is that the screen simply won't suspend or turn off( via software), DPMS actually works, forcing it turns the screen blank for some seconds but something does not allow the screen to sleep.
Performance wise it seems pretty good though, everything is pretty smooth, being able to play games maxed out on resolution and ultra settings, though, I still haven't tested out that many games.
The open-source radeon on the other hand, well its open-source, fully xorg and linux compatible, which is a major plus point. It seem it has come a long way, supporting lot of features and providing better performance in some cases.
Before installing Catalyst I had issues with mesa and steam, steam would complain about not finding the 32bit libraries, this is however a steam runtime issue, maybe it could already be fixed.

We all know we can install a linux system such as Fedora 10 and use it. Being linux, one should in principle get the source codes for everything that has been precompiled (except the proprietary drivers such as nvidia) in the installation DVDs/CDs. Where are the source codes ? Is there a place I can download them ?
To avoid confusion, I am not referring to the kernel source that can be compiled to give a linux kernel, but that does not include the drivers, such as intel_drv.so.
To be more specific, the intel graphic i810 driver has been built into any linux system, but where is the exact source? One answer may be that primary source intellinuxgraphics.com. However, if anyone tries to download the every changing (i.e., keep updated almost every single day) driver source codes from freedesktop.org, it is almost certain that the source codes will not be the same as the one that is finalized in Fedora 10.

When I use the arrow keys it gives me alphabets A B C D. And also when i press a . it acts as a backspace.I have a cordless Logitech Keyboard.I don't know why my keyboard isn't functioning inside the Terminal (& that to only whilst typing in source codes) I have tried changing the Character Encoding but thats not helping.

I have a while(1) loop, and the error is: glibtop: open (/proc/stat): Too many open files This error occurs after about a half hour to an hour of running. I've tried running this multiple times, both with using glib_close() at the end of the loop, using glib_init() and glib_close() at beginning/end, and just using glib_init(). The strange thing is these have no effect on the actual glib_get functions.
