• Anyone know how to get an LTSP image working with VIA VX855 chipset?

  - by Bryan

  I'm running an LTSP server on Ubuntu 11.10 and can load the i386 image via PXE boot on a VirtualBox VM just fine. However, when I PXE boot a Dell FX130 thin client on the LTSP network the login screen ends up being a white screen with a bunch of wavy black lines going up and down it. The 11.10 splash screen displays just fine as the image is booted, then I get a "INVALID CARD NUMBER" message, then a black screen, then finally the white screen with wavy lines. I'm not sure if the "INVALID CARD NUMBER" message has anything to do with the issue, but in the end the white screen with wavy lines makes me think it's a video driver problem. On the LTSP server, I chrooted into /opt/ltsp/i386 and made sure xserver-xorg-video-openchrome was installed. I did notice that no xorg.conf exits in /etc/X11 though.

  Andrejus Baranovskis: Oracle OpenWorld 2010 - Developing Large Oracle ADF 11g Applications Oracle ACE Director Andrejus Baranovskis shares a preview of the presentation he will give at Oracle OpenWorld 2010. (tags: oracle otn oracleace oow10) Andy Mulholland: Complicated or complex architecture or solutions "Enterprise architecture, and EAI middleware, is not likely to be the answer to this, instead we should be looking at provisioning through using the granularity of ‘services’ as opposed to the monolithic approach of applications. Actually it’s not one or the other, it’s both used together. The goal is to introduce an abstraction layer between the core processes represented by applications connected together through closed coupled middleware in defined relationship, and the loose coupled environment of services with the flexibility of orchestrations. At least in part the ability of drag and drop tools to produce orchestrations ‘on-demand’ starts the change towards user-driven views on ‘outcomes’ that suit them rather than the computer’s database." Andy Mulholland (tags: enterprisearchitecture architect businessalignment government) @chrismuir: One size doesn't fit all: ADF and WLS JNDI configuration errors Oracle ACE Director Chris Muir shares "Another blog under the theme 'let's document it so we don't get caught out again', which can also be tagged as 'let's document it so others don't get caught out too.'"

• Replace %26 in htaccess to %2526

  - by Patrick

  I would like htaccess to rewrite example.com/something_%26_else into example.com/something_%2526_else. I'm importing a bunch of pages that have ampersands in the title from Mediawiki. These are encoded as %26. Drupal, for various reasons, has decided double encode the url it to have it become %2526. I simply can't create the alisis within Drupal so I have to use htaccess This is what I have as my rule so far as RewriteRule ^w/([^%26]+)\%26(.*)$ w/$1\%2526$2 [R=301] I asked this question three months ago on stackexchange and was not able to get it working. I tried hiring a contractor for this but was unable to find one. So this my last ditch effort before I completely give up. I really appreciate the help. All the best, Patrick

• OT: Airlines and Podcasts

  - by Greg Low

  Those that know me know that I spend an inordinate amount of time on airlines. I also love podcasts, as you can tell from my www.sqldownunder.com site and show. So anything that combines the two is just awesome. Fly With Joe fits that perfectly. Joe D'Eon provides great insights in his show. I was sad last year that he hadn't posted many shows. I've also been quiet for a couple of months (but that's about to change with a bunch of SQL Server 2008 R2 shows). But I've been so pleased that Joe's got...(read more)

• ADF sessions at UKOUG conference by Grant Ronald

  - by JuergenKress

  For those in the UK, or those who have a few travel dollars left in their budget I just wanted to hi-light a couple of reasons you might want to present to your management as to why you should attend the UKOUG conference this year to get your ADF fill. Firstly, there are three days packed with the ADF content from the brightest minds in ADF-land. In no particular order, some of the stand out sessions for me will be: Duncan Mills presenting a keynote on the Future of Oracle's Fusion Development Luc Bors will be demoing ADF Mobile Frank Nimphius will be giving a tour around JDeveloper 12c Steven Davelaar of JHeadstart fame will be giving an insight on task flows and ADF Faces. Aino Andriessen will focus on build and deployment Frank Houweling will tell us how he can make your ADF application run 70% faster Chris Muir will give a masterclass on ADF architecture. In addition, the UKOUG will be running a 3 days of ADF Mobile hands-on sessions. Mobile is just about the hottest development topic at this time so this is an ideal opportunity to roll up your sleeves and build on-device mobile applications. There will also be a roundtable discussion on which development tool is right for you, and a roundtable on the strategic importance of ADF. Of course, the conference is not all about ADF; Tom Kyte will be there, Cliff Godwin (SVP who looks after Oracle Applications) and a host of others. This might be a great opportunity to get some ADF education. For more adf information visit Grant Ronald’s blog.

• Orlando .NET Code Camp 2012 - total success..

  - by mrad

  Their site is www.orlandocodecamp.comThis year's camp was held at Seminole State College.It was well worth it.. Took a chance at going.. by getting up at 5am and driving from Jax to Sanford for 2+hr..Run into some old friends and bunch of new ones. Coders are not really good at networking.. but they sure did show up.. attendance was solid 500+ geeks and some sessions were standing room only. MVP John Papa had the room packed out on his every session. Really enjoyed great and inspiring WP7 presentations by MVP Atley Hunter from Canada.. And of course the MVP legend Joe Healy was everywhere encouraging and promoting cool stuff, hopefully we'll get him back to present at JaxDUG and/or bring back Microsoft workshops to Jax area.

• Web services, J2EE, Spring, DB integration project ideas - maybe data mining related?

  - by saral jain

  I am a graduate Computer Science student (Data Mining and Machine Learning) and have good exposure to core Java (3 years). I have read up on a bunch of stuff on the following topics: Design patterns, J2EE Web services (SOAP and REST), Spring, and Hibernate Java Concurrency - advanced features like Task and Executors. I would now like to do a project combining this stuff -- over my free time of course -- to get a better understanding of these things and to kind of make an end to end software (to learn the best design principles etc + SVN, maven). Any good project ideas would be really appreciated. I just want to build this stuff to learn, so I don't really mind re-inventing the wheel. Also, anything related to data mining would be an added bonus as it fits with my research but is absolutely not necessary since this project is more to learn to do large scale software development.

• Exposing business logic as WCF service

  - by Oren Schwartz

  I'm working on a middle-tier project which encapsulates the business logic (uses a DAL layer, and serves a web application server [ASP.net]) of a product deployed in a LAN. The BL serves as a bunch of services and data objects that are invoked upon user action. At present times, the DAL acts as a separate application whereas the BL uses it, but is consumed by the web application as a DLL. Both the DAL and the web application are deployed on different servers inside organization, and since the BL DLL is consumed by the web application, it resides in the same server. The worst thing about exposing the BL as a DLL is that we lost track with what we expose. Deployment is not such a big issue since mostly, product versions are deployed together. Would you recommend migrating from DLL to WCF service? If so, why? Do you know anyone who had a similar experience?

• Learning a new language using broken unit tests

  - by Brian MacKay

  I was listening to a dot net rocks the other day where they mentioned, almost in passing, a really intriguing tool for learning new languages -- I think they were specifically talking about F#. It's a solution you open up and there are a bunch of broken unit tests. Fixing them walks you through the steps of learning the language. I want to check it out, but I was driving in my car and I have no idea what the name of the project is or which dot net rocks episode it was. Google hasn't helped much. Any idea?

• Xubuntu: Disks utility (palimpsest) and Gparted not showing up anywhere after installation

  So I've downloaded Gparted and Disks from the software center. According to software center, they've both installed successfully... but they're nowhere to be found. Even in my terminal: $ palimpsest palimpsest: command not found I've looked in usr/bin... no "palimpsest", no "gnome-disk-utility". In usr/share/gnome-disk-utility there's a bunch of .ui files. According to Software Center, both programs are now installed in my computer, but it seems I've no way to find them. I've tried re-installing and restarting. I'm on Xubuntu 32 bit.

• 2D Tile-Based Concept Art App

  - by ashes999

  I'm making a bunch of 2D games (now and in the near future) that use a 2D, RPG-like interface. I would like to be able to quickly paint tiles down and drop character sprites to create concept art. Sure, I could do it in GIMP or Photoshop. But that would require manually adding each tile, layering on more tiles, cutting and pasting particular character sprites, etc. and I really don't need that level of granularity; I need a quick and fast way to churn out concept art. Is there a tool that I can use for this? Perhaps some sort of 2D tile editor which lets me draw sprites and tiles given that I can provide the graphics files.

• Drawing graphics in Java game

  - by wolf

  I am quite new to game development, so here is a question (maybe a stupid one): In my sidescroller i have a bunch of different graphics objects that i need to draw (player, background tiles, creatures, projectiles etc). Most tutorials i've read so far show that each object has its own draw method, which is then called from some other method. What if I had one method that does all the drawing? Lets say i keep all my objects in an array or queue (or multiple arrays) and then go through each of them, get an image and draw it. So basically would it be better (and why) to have each object have its own draw method or one method that does all the drawing? Or does it matter at all? I feel like the second option is more comfortable, because then all the stuff to do with drawing would be in one place...

• Have I fixed my partition problem with os x 10.5.8? Are my GPT and MBR back to normal?

  - by David Schaap

  I'm new to linux and I have overstepped by abilities. I tried dual booting os x 10.5.8 with ubuntu 11.10 with rEFIt, but I been having problems with partitioning. Instead of enduring more headaches, I've made the decision to simply use ubuntu on VirtualBox. I've tried to return my HDD to normal, but I am looking for confirmation that my partitions are ok. Here is the report from partition inspector: *** Report for internal hard disk *** Current GPT partition table: # Start LBA End LBA Type 1 409640 233917359 Mac OS X HFS+ Current MBR partition table: # A Start LBA End LBA Type 1 1 234441647 ee EFI Protective MBR contents: Boot Code: GRUB Partition at LBA 409640: Boot Code: None File System: HFS Extended (HFS+) Listed in GPT as partition 1, type Mac OS X HFS+ Also, my HDD directory has a bunch of extra folders in them and they appear to be ubuntu related, although it is no longer installed. folders like bin, sbin, cores, var, user, and so on. Those folders aren't supposed to be there, right? Thanks in advance.

• Just updated, after reboot my computer won't start up again

  - by Alex

  I have a macbook that I use on occasion which dual boots Ubuntu and OSX (It has rEFIt installed). I turned it on for the first time in a while and it needed a bunch of updates. So I let it run, and restarted it when it asked. When it was booting up, it got stuck at a light blue screen. There was nothing on the screen to indicate that it was doing anything - I figured it just got stuck or something, so I turned it off and back on. (I suspect now it was actually working, but I had no indication that it hadn't just frozen) Now I can't access either OSX or my Ubuntu partition. When I choose ubuntu on the rEFIt menu, it shows "No bootable device -- insert book disk and press key". If I try to start up OSX is looks like it starts loading, but instead of an apple logo there's a crossed out circle icon.
