• We'll be at QCon San Francisco!

  - by Carlos Chang

  Oracle Technology Network is a Platinum sponsor at QCon San Francisco. Don’t miss these great developer focused sessions: Shay Shmeltzer - How we simplified Web, Mobile and Cloud development for our own developers? - the Oracle Story Over the past several years, Oracle has beendeveloping a new set of enterprise applications in what is probably one of the largest Java based development project in the world. How do you take 3000 developers and make them productive? How do you insure the delivery of cutting edge UIs for both Mobile and Web channels? How do you enable Cloud based development and deployment? Come and learn how we did it at Oracle, and see how the same technologies and methodologies can apply to your development efforts. Dan Smith - Project Lambda in Java 8 Java SE 8 will include major enhancements to the Java Programming Language and its core libraries.  This suite of new features, known as Project Lambda in the OpenJDK community, includes lambda expressions, default methods, and parallel collections (and much more!).  The result will be a next-generation Java programming experience with more flexibility and better abstractions.   This talk will introduce the new Java features and offer a behind-the-scenes view of how they evolved and why they work the way that they do. Arun Gupta - JSR 356: Building HTML5 WebSocket Applications in Java The family of HTML5 technologies has pushed the pendulum away from rich client technologies and toward ever-more-capable Web clients running on today’s browsers. In particular, WebSocket brings new opportunities for efficient peer-to-peer communication, providing the basis for a new generation of interactive and “live” Web applications. This session examines the efforts under way to support WebSocket in the Java programming model, from its base-level integration in the Java Servlet and Java EE containers to a new, easy-to-use API and toolset that are destined to become part of the standard Java platform. The complete conference schedule is here: http://qconsf.com/sf2012/schedule/wednesday.jsp But wait, there’s more! At the Oracle booth, we’ll also be covering: Oracle ADF Mobile Oracle Developer Cloud Service Oracle ADF Essentials NetBeans Project Easel Hope to see you there!

• Transmission shutdown script for multiple torrents?

  - by Khurshid Alam

  I have written a shutdown script for transmission. Transmission calls the script after a torrent download finishes. The script runs perfectly on my machine (Ubuntu 11.04 & 12.04). #!/bin/bash sleep 300s # default display on current host DISPLAY=:0.0 # find out if monitor is on. Default timeout can be configured from screensaver/Power configuration. STATUS=`xset -display $DISPLAY -q | grep 'Monitor'` echo $STATUS if [ "$STATUS" == " Monitor is On" ] ### Then check if its still downloading a torrent. Couldn't figure out how.(May be) by monitoring network downstream activity? then notify-send "Downloads Complete" "Exiting transmisssion now" pkill transmission else notify-send "Downloads Complete" "Shutting Down Computer" dbus-send --session --type=method_call --print-reply --dest=org.gnome.SessionManager /org/gnome/SessionManager org.gnome.SessionManager.RequestShutdown fi exit 0 The problem is that when I'm downloading more than one file, when the first one finishes, transmission executes the script. I would like to do that but after all downloads are completed. I want to put a 2nd check ( right after monitor check) if it is still downloading another torrent. Is there any way to do this?

  I just bought this notebook and I've already installed in a new partition Ubuntu 12.04 LTS with 6gb of swap memory. UPDATE2: This is the laptop configuration: http://h10025.www1.hp.com/ewfrf/wc/document?cc=it&lc=it&dlc=it&tmp_geoLoc=true&docname=c03397517 Sometimes (without any special conditions) Ubuntu freezes.

I can only press on power button (physically) and restart my laptop (and this is not the correct way to do things). I'm using this laptop for work, so I need a stable OS without this freeze. Someone knows how to solve this problem? UPDATE: /var/log/messages is empty /var/log/kernel.log - http://paste.ubuntu.com/1220182/ /var/log/Xorg.0.log - http://paste.ubuntu.com/1220186/ I just installed propetary driver from ATI, it crash anyway.

• Keeping files that are often changed in sync between desktop and laptop

  - by N.N.

  I'm looking for a way to keep a desktop and a laptop in sync. What I want to keep in sync are some folders, mainly ~/Documents, that are changed often when working on them. If it matters I can connect to my desktop from anywhere via an URL but my laptop is harder to access since it might be behind NAT and such. I have been looking at Ubuntu One but it seems to not go well with working on documents written in LaTeX. If I work on a .tex file in the Ubuntu One directory and compile it (with pdflatex) every now and then (as often as every 10 sec when working) it will create several new files including a pdf which are uploaded to Ubuntu One and this seems stupid since it will create continuous upload when working on .tex files. I also usually keep .tex documents version controlled by git and then every commit (which also can happen frequently) will cause upload (by changes in ./.git) so that it happens continuously when working. Another example is editing images that are saved often. What I think would be best is for sync to happen every tenth minute or at the end of every working session (but there might be some other way to handle this?).

• Windows Randomly Stop Accepting Input from Bluetooth Keyboard

  - by dragonmantank

  I've got a laptop running Ubuntu 11.10 with the most recent updates and an Apple Wireless Keyboard that syncs via bluetooth. The Ubuntu box is also a Synergy server, using QuickSynergy to run Synergy. I'm using xmodmap to swap the option and command keys, but nothing else. Throughout the day, windows that are long running will just stop accepting input. For example, I leave gnome-terminal up and running almost 24 hours a day. If it sits for a while, it just stops accepting input. It doesn't matter if I'm ssh'd into another machine or sitting on a local tty session, it just stops accepting input. If I open a new tab or window, those work fine. The 'broken' tabs stay broken. I'm also running Turpial (a Twitter client) which will do that same thing. I tend to use the arrow keys to navigate, and it just stops accepting input. Closing it and reopening it causes it to work fine. I don't seem to have the problem in Chrome, but I tend to open up new tabs when I go somewhere instead of using existing tabs. I've updated all the packages, rebooted, and the only thing that seems to cure it is if I type on the built-in keyboard, the window will start to accept text from the bluetooth keyboard (until it stops again). I don't think the keyboard is disassociating from the laptop because it can happen while I'm using the keyboard, it seems more linked with windows that I sit for a long time. As an example, I'm typing in Chrome with the bluetooth keyboard but I have a terminal window that won't accept input.

  - by Bob Rhubart

  Eye on Architecture This week the Oracle Technology Network Solution Architect Homepage features an Oracle Reference Architecture for Software Engineering, a new podcast focusing on why IT governance is important whether you like it or not, and information on the next free OTN Architect Day event. Enabling WebLogic Administrator Group Inside Custom ADF Application | Andrejus Baranovskis A short but informative technical post from Oracle ACE Director Andrejus Baranovkis. Oracle OpenWorld 2012 Hands-on Lab: Leading Your Everyday Application Integration Projects with Enterprise SOA Yet another session to squeeze into your already-jammed Oracle OpenWorld schedule. This hands-on lab focuses on how "Oracle Enterprise Repository, Oracle Application Integration Architecture (AIA) Foundation Pack, and Oracle SOA Suite work together to help you drive your enterprisewide integration projects." Mass Metadata Updates with Folders | Kyle Hatlestad "With the release of WebCenter Content PS5, a new folder architecture called 'Framework Folders' was introduced," explains Fusion Middleware A-Team blogger Kyle Hatlestad. "This is meant to replace the folder architecture of 'Folders_g'. While the concepts of a folder structure and access to those folders through Desktop Integration Suite remain the same, the underlying architecture of the component has been completely rewritten." Creating your first OAM 11g R2 domain | Chris Johnson Prolific Fusion Middleware A-Team Blogger Chris Johnson reads the Oracle Identity and Access Management Installation Guide so you don't have to (though you probably should). Thought for the Day "Each pattern describes a problem which occurs over and over again in our environment, and then describes the core of the solution to that problem, in such a way that you can use this solution a million times over, without ever doing it the same way twice." — Christopher Alexander Source: SoftwareQuotes.com

• TechEd 2010 - New Orleans

  - by gjfox

  We're a little more than half way through TechEd 2010 in New Orleans and I am having a hard time finding interesting breakout sessions to attend.  Laura Chappell has completed all of her sessions, and Andy Malone is almost done.  Laura's sessions on Wireshark have been amazing.  Andy is always entertaining and informative.  I did sit through a session this afternoon on IPv6 that was interesting.  I will spend the final day in the Hands on Labs area working through some PowerShell, and Communication Server 14 labs.  The speakers for two of my breakouts had written interesting books.  I went to the conference bookstore to pick them up and found both to be sold out.  They did offer to ship the books to me with the TechEd 20 percent discount. I'm not real sure who thought it would be a good idea to hold a conference in June in New Orleans.  It has been HUMID.  On top of that TechEd 2011 will be in my hometown, Atlanta.

• Gigabyte u24f Touchpad (elantech) not detected

  - by user314973

  A new Ubuntu user here. I just installed Ubuntu 14.04 on my gigabyte U24F laptop. At first the touch-pad (I believe it's elantech) was working fine but one day I turned it off using fn+f10 key from the keyboard. The next day I could no longer turn it back on and it has since been undetected by the system. xinput returns Virtual core pointer id=2 [master pointer (3)] ? ? Virtual core XTEST pointer id=4 [slave pointer (2)] ? ? Logitech USB Optical Mouse id=11 [slave pointer (2)] ? Virtual core keyboard id=3 [master keyboard (2)] ? Virtual core XTEST keyboard id=5 [slave keyboard (3)] ? Power Button id=6 [slave keyboard (3)] ? Video Bus id=7 [slave keyboard (3)] ? Sleep Button id=8 [slave keyboard (3)] ? Video Bus id=9 [slave keyboard (3)] ? Power Button id=10 [slave keyboard (3)] ? AT Translated Set 2 keyboard id=12 [slave keyboard (3)] so there's no touch-pad detected. I'm using a USB mouse at the moment. Attempting to run synclient gives "Couldn't find synaptics properties. No synaptics driver loaded?" Things I've tried so far to no avail Reinstalling xserver-xorg-input-synaptics. Checking dconf.editor settings, touchpad is enabled. Booting into a live usb session, touchpad no longer even works in this case. (Does this mean a fresh install wouldn't even solve the problem?) Any help is greatly appreciated!

• How do I install 10.04 on a Vortex86DX embdedded system?

  - by mathematician1975

  I am trying to install Ubuntu on a Netcom NC-499 board that contains a Vortex86DX processor. The processor vendor claims support for Ubuntu 10.04 but I am having problems installing it. I am trying to install to a 8GB compact flash card attached to the board with an IDE connector, using a USB connection CD-Rom drive and a burned ISO image obtained from this link http://old-releases.ubuntu.com/releases/10.04.0/ubuntu-10.04.3-desktop-i386.iso . Installation proceeds up to the point of around 78% but during the stage where the installer informs me that it is "configuring apt", the installer terminates with a popup dialog containing the following "The installer encountered an unrecoverable error. A desktop session will now be run so that you may investigate the problem or try installing again." I have no idea what to do at this point. I am a Linux novice and I do not really know how to investigate the problems with the installation. I have configured the BIOS exactly according to how the vendor specifies and they assure me that this version is fully compatible with their hardware and yet I am unable to get a decent install. I am able to install Ubuntu 8.04 using exactly the same procedure successfully so I am sure there is no problem with my CD-Rom compatibility or the compact flash drive. Any help will be gratefully received.

• Get external metadata with streamripper using python script

  - by user72379

  Hi I like using streamripper to rip music from the web. I have a favorite radio station that doesn't have the metadata for the songs, so I have to screen scrape it from its website manually. I created this neat python script in the format that the docs suggest, and linked the address in the GUI for streamriper. But it still doesn't work, any one know how to make it work..? I know it used to work. It gives you a sample here: http://streamripper.sourceforge.net/history.php import http import time import re u = 'SEE IMAGE FOR THIS URL' s = http.Session(0, 0) s.add_headers(h, persistent=1) while 1: c = unicode(s.get(u)) pat = r'class="title"([^<]+)([^<]+)' m = re.search(pat, c) title = m.group(1) artist = m.group(2) print 'TITLE='+title+'\n'+'ARTIST='+artist+'\n.\n' time.sleep(30) [img]http://s11.postimage.org/sok928lsz/urlstream.png[/img] I put the address to the script here: [img]http://s17.postimage.org/4bhmhi4yn/streamripper.png[/img] I've tried putting it in the root of the streamripper application and doing this: lax.py I've even compiled it to a EXE, and tried linking to that.. nothing What am I doing wrong?

• Joomla Secondary Users

  - by Gaz_Edge

  Background I have a joomla based application. My customers sign up and they register as a user on the site. My customers (primary customers) then have their own space on the site that they can then setup their own customers (secondary customer). Question/Problem The problem I am having is that I need to tag each secondary customer to a primary customer. I thought about just creating a new component and having a separate table that includes all the secondary customers. The problem is that I then lose out on all the authentication, session handling and login/logout that the core joomla _users component offers. I then thought about just having all the users in the core _users table and add the primary customer associated with each secondary customer to a field in a profile plugin. This would work for the most part, but this means that primary customers cannot create a secondary customer with a user name that already exists in the _users table. I didn't think this would be an issue, but several of my primary customers (currently only test users) have been confused by the site telling them a username is not available, since they can only see the names of their own secondary customers. Any ideas on some architectural changes I could make to solve this?

• loading splash screen takes priority over terminal or windows manager while running elsa

  - by schonjones

  I recently installed e17 and was trying to set up defaults to use elsa and ecomorph over the standard compiz as it constantly crashes since updating to 12.04. If elsa is installed the loading screen hangs and never loads to login, however i can get to a terminal or the e17 login instead of the standard gdm that usually shows up, within a second the screen goes back to the loading screen. I can still type and login as well as run commands in the terminal, but all I see is the loading screen. Switching between terminals i can confirm my commands before it switches back to the loading screen. If i remove elsa the loading screen hangs, but I can get to a terminal login and run lightdm to start my session with no problems. I have multiple DE installed and am unsure which loading screen is coming up. i think it's the KDE screen, grub comes up with a debian background if that helps. I'm not sure if i can switch the loading screen and resolve this issue or if i'm just going to have to scrap using elsa and get lightdm to load on boot again. Elsa would be my preference. I don't have the space to backup my files for a complete reinstall. Please help!

• Battery is drained too quickly

  - by LucaB

  I'm getting really low battery life under ubuntu, not even close to windows. I tried powertop, and I saw that my laptop is consuming in idle nearly 20 watts (a bit more). I tried to install laptop-mode-tools, change "good" into "bad" in powertop, but nothing changes. I see that I have the the HD audio output device which is running at 100% every time. Could this be the problem? This is a report from powertop.

• JavaOne + Develop Registration is Open!

  - by justin.kestelyn

  Welcome to "The Zone". Here's what the new JavaOne + Develop registration Website says: The world's most important developer conferences are creating the world's coolest neighborhood for the developer community. Having been intimately involved in the planning process, I can vouch for that statement. Remember, if either co-located conference - JavaOne or Oracle Develop - are the confines of your interest, you can experience either one in standalone mode, if you like (although there are some areas of common interest, of course). Or, considering that a single Full Conference Pass gives you access to both of them, you can partake in any measure that you like. It's up to you. Either way, you will get access not only to session content and keynotes, but also to the massive OTN Night party on Monday night, to open unconference sessions, and to the legendary Appreciate Night concert (acts TBD) on Wednesday. Furthermore, as is customary, the Oracle Technology Network team will offer a full slate of community-focused activities and goodies while the conferences are running - more details on those as we have them. A GOOD time is ensured for all; I look forward to seeing you there!

• Would a typical corporate firewall block a Java applet having the following behaviour

  - by auser

  I'm thinking of developing a proxy-like program to forward ports on a remote PC to a local PC (for example SSH). Assume that both local and remote PCs are running behind typical firewalls (i.e. consumer broadband router firewall, Windows firewall or corporate firewalls). The program will be a Java program which the user will run on both the remote and local PC. The remote client will periodically poll a central server to determine whether there are pending client connections. A session could be initiated as follows: The local client contacts the central server and request the current connection details for a specific remote client. The central server responds with the remote server's last received IP address and port. The next time the remote server polls the central server, the client's IP address and port are returned. The remote server initiates a connection to the local client using the IP address and port returned by the central server and listens for a response on a random port. The remote server will pass the value of the port it's listening on to central server. Goto 1, if client fails to connect to server. Would this work or will a typical firewall block the interactions.

• Sustainability at Oracle OpenWorld

  - by Oracle OpenWorld Blog Team

  By Evelyn Neumayr Leading businesses - not to mention individuals - recognize that environmental responsibility is good business. Well-thought out and well-structured environmental practices deliver triple benefit: to people, profits, and our planet. IT, as a central part of most organizations' business strategies, plays a pivotal role in developing environmental initiatives. Any Oracle OpenWorld attendee interested in learning how to use Oracle products to reduce both their organization’s environmental footprint, as well as their costs, should attend one of the many sustainability sessions being held at the conference. If you can only attend one sustainability-focused session, this is the one not to miss, where you can learn about innovative sustainability practices from customers on the leading edge. Eco-Enterprise Innovation Awards and the Business Case for SustainabilityWednesday, October 3, Moscone West 300510:15 - 11:15 a.m. If you can attend several sessions that have a sustainability focus, look here to find the listing of sessions that drill down into a specific product, where the discussion will focus on how that product can help achieve sustainability while improving enterprise operational efficiencies. Regardless of size and scope, all efforts are worthwhile. To learn more, go to the Sustainability Matters blog.

• What to do when 'dpkg --configure -a' fails with too many errors?

  - by rudivonstaden

  During an upgrade from lucid (10.04) to precise (12.04), the X session froze, and I have been trying to recover the upgrade to get a stable system. I have performed the following steps: Used ssh to log in to the stalled system over the network. Checked the contents of the /var/log/dist-upgrade directory. There was no activity on main.log, apt.log or term.log. top showed that process 'precise' was using about 3% CPU, but I could find no evidence that the upgrade process was still doing anything. 'dpkg' did not show up in top, but it came up with pgrep dpkg | xargs ps Killed the 'dpkg' and 'precise' processes Tried to recover the upgrade by running sudo fuser -vki /var/lib/dpkg/lock;sudo dpkg --configure -a. This was partially successful (some packages were configured), but failed with the message Processing was halted because there were too many errors. I ran the same command a few times, and each time some packages were configured but others failed. Tried running sudo apt-get -f install. It fails with similar errors to dpkg. The current situation is that dpkg --configure -a and sudo apt-get -f install fails with two kinds of error: Dependency issues, e.g.: dpkg: dependency problems prevent configuration of cifs-utils: cifs-utils depends on samba-common; however: Package samba-common is not configured yet. dpkg: error processing cifs-utils (--configure): dependency problems - leaving unconfigured Resource conflict, e.g.: debconf: DbDriver "config": /var/cache/debconf/config.dat is locked by another process: Resource temporarily unavailable Additionally, it seems there's reference to potential boot problems, so I'm not keen to reboot without fixing the install first: dpkg: too many errors, stopping Processing triggers for initramfs-tools ... update-initramfs: Generating /boot/initrd.img-3.2.0-25-generic cryptsetup: WARNING: failed to detect canonical device of /dev/sda1 cryptsetup: WARNING: could not determine root device from /etc/fstab So my question is, how to get a working install when dpkg --configure -a fails?
