• Unleash the Power of JavaFX

  - by Angela Caicedo

  It seems that it was just yesterday that we were getting ready for JavaOne 2012.  Now it's over, but it's definitely a great time to go back and watch the sessions you missed, and learn some of the latest news about Java.   For this JavaOne, I presented two sessions and one HOL, all of them related to JavaFX: JavaFX Extreme GUI Makeover Building JavaFX Interfaces with the Real World Unleash the power of JavaFX If you couldn't join us for these sessions, just follow the links and you can watch the videos on demand. For the HOL I've created a repository at GitHub, as many of the attendees wanted to keep the material.   In this repository you can find the lab document, the NetBeans projects for each exercise and it's appropriate solution.  Hope you enjoy! I created and presented a HOL called:  Unleash the power of JavaFX.  In this blog entry I would like to provide you

• Getting Started Quickly

  - by Owen Allen

  If you're interested in using Ops Center, you'll want to get up and running as quickly and effectively as possible. One way to do this would be to work your way through the documentation library - use the Linux or Oracle Solaris install guides, then go through the Feature Guide and Admin Guide to start using the software. They're thorough, but they're a lot of reading. But if you're looking to install a simple deployment quickly, and you don't want to do all of the configuration work right off the bat, you can use the Quick Start Guide. It's a streamlined procedure that runs you through installing a single Enterprise Controller and co-located Proxy Controller, and then shows you how to discover assets quickly. Once you've discovered these assets, it describes how to use the analytics feature to view their performance, and use monitoring to keep track of their statuses and health. You'll have to do some additional configuration to use features like OS provisioning, OS updates, and virtualization, but the Quick Start guide gives you an overview of how to install and start using features quickly.

• Calling Web Service with Complex Parameters in ADF Mobile

  - by Shay Shmeltzer

  Many of the SOAP based web services out there have parameters of specific object types - so not just simple String/int inputs. The ADF Web service data control makes it quite simple to interact with them. And this applies also in the case of ADF Mobile. Since there were several thread on OTN asking about this - I thought I'll do a quick demo to refresh people memory about how you pass these "complex" parameters to your Web service methods. By the way - this video is also relevant if you are not doing mobile development, you'll basically use the exact same process for building "regular web" ADF applications that access these types of Web services. One more thing you might want to do after you create the page is look at the binding tab to see the method call in there, and notice the parameters for it in the structure property. Go and look at their NDValue property to get the complete picture.

• Disabling IPv6 on a single interface

  - by ijw

  I'm slightly weirded out by the fact that Ubuntu won't process ipv4 DHCP unless you explicitly tell it to, but will happily take ipv6 RAs unless you tell it not to. Is there any way to change the default behaviour to be 'do nothing unless I explicitly turn it on'? (Note to answerers: I'm not looking to globally disable ipv6, or completely turn off autoconf. I'm looking to disable autoconf by default (as in, I don't want ipv6 unless I say so in /etc/network/interfaces, in the same way that I don't just get a v4 address unless I've explicitly turned on dhcp). What's happening is that, for any interface that's up - e.g. has an ipv4 config - a v6 address tends to just turn up on the interface as well, despite the fact that I've not enabled that explicitly. The solutions to date are fine as far as they go, but if I disable v6 or autoconf globally, I can't then re-enable v6 on a per-interface basis with a simple command in /etc/network/interfaces. I'm fairly sure I'm asking for the moon on a stick, mind you.)

• GA tracking utm query params after hashbang

  - by hybrid9

  We currently use a hashbang for the portion of our site that generates dynamic content which can also be deep linked. Our analytics team wants to use utm params to track the referral traffic from social networks. We are using Universal Analytics (analytics.js) as well as GTM. Will GA pick up the query parameters after the hashbang or does it always have to go before? For example: example.com/#!/some/content?utm_source=foo&utm_campaign=bar example.com?utm_source=foo&utm_campaign=bar/#!/some/content In #1, I'm concerned that the utm params won't be recorded and in #2 the page will break or the url could be incorrectly written. How does GA pull in those parameters - location.search? regex? Can I get away with using either?

• Creating basic ACPI event makes the system unusably slow

  - by skerit

  I want to change a few settings on my laptop when I switch to battery power. I created a new event in /etc/acpi/events/cust-battery and it looks like this: event=battery action=/home/skerit/power.sh I put a simple command in the power.sh file: echo This is a test >> /home/skerit/powertest Now, when I tail this file it shows "This is a test" 4-5 times upon switching to battery power. However, the system becomes totally unstable. It slows down significantly. I can't change anything in the terminal. The terminal and certain parts of the screen (like the gnome system monitor applet) go blank from time to time. What can be the cause of that? It's a simple echo that gets executed a few times!

• Using 301 Redirects on new site when access to old site denied?

  - by Cape Cod Gunny

  I have a situation where I'm standing up a new website on a different web host. I've been denied access to the old site by the hosting company and the old site will most likely be turned off very soon. If my new site contains pages that are named slightly different how do I go about setting up 301 redirects on my new site? For example: www.oldsite.com\aboutus\ www.newsite.com\aboutus.html www.newsite.com\productx.html www.oldsite.com\productx\ Edit: Clarification: The old domain name is different from the new domain name. On my newsite do I just duplicate every page that existed on the old site and place redirect code inside those pages? What does the redirect code look like?

  - by Marco Russo (SQLBI)

  I will deliver two sessions at the next PASS Summit 2012: one is title Inside DAX Query Plans and the other is Near Real-Time Analytics with xVelocity (without DirectQuery).These will be two sessions that require a lot of preparation and even if I have already much to say, I still have a long work to do this summer in order to go deeper in several details that I want to investigate for completing these sessions.I already look forward to come back in Seattle!In the meantime, you have to study SSAS Tabular and if you want to get a real jumpstart why not attending one of the next SSAS Tabular Workshop Online?

• Managing multiple people working on a project with GIT

  - by badZoke

  I'm very new to GIT/GitHub (as new as starting yesterday). I would like to know what is the best way to manage multiple people working on the same project with Github. Currently I'm managing one project with four developers. How do I go about the workflow and making sure everything is in sync? (Note: All developers will have one universal account.) Does each developer need to be on a different branch? Will I be able to handle 2 people working on the same file? Please post a detailed answer, I'm not a shy reader. I need to understand this well.

• Unit testing a text index

  - by jplot

  Consider a text index such as a suffix tree or a suffix array supporting Count queries (number of occurrences of a pattern) and Locate queries (the positions of all the occurrences of a pattern) over a given text. How would you go about unit testing such a class ? What I have in mind is to generate a big random string then extract a random substring from this big string and compare the results of both queries with naive implementations (such as string::find). Another idea I have is to find the most frequent substring of length l appearing in the original string (using perhaps a naive method) and use these substrings for testing the index. This isn't the best way, so what would be a good design of the unit tests for a text index ? In case it matters, this is in C++ using google test.

• Keyboard shorcut for a custom folder in Desktop

  - by palerdot

  I would like to configure a keyboard shortcut for a particular folder in my Desktop. I will be using this folder quite often and is there a way to open them with a custom keyboard shortcut ? The remote thing I came across regarding this is this question which is for opening home folder similar to Windows, but I do not want to go to home folder and navigate from there all the way to a folder in the Desktop (mouse clicking the desktop folder is way too easier than this method). So my Question: Can I have custom keyboard shortcuts for custom folders like folders in Desktop ? I'm using 12.04.

• How to track in Google Analytics registrations come from Google AdWords ads?

  - by automatix

  I created a campaign in Google AdWords and some ads in it and gave them URLs like mydomain.tld/registration/?utm_campaign=mycampaing&ad=x mydomain.tld/registration/?utm_campaign=mycampaing&ad=y mydomain.tld/registration/?utm_campaign=mycampaing&ad=z All ads lead to the registration page. A registration is a visit of the page mydomain.tld/registration-complited/?user={ID} So I can track the registrations in Google Analytics. I just go to Behavior -> Site Content -> All Pages and filter the pages to registration-complited. But how can I see, how many and which users have registered, after they came from an ad of a campaign, e.g. utm_campaign? And how can I also track this for a sigle ad of the campaign, e.g. x?

• Do employers hiring for software jobs care about the classes you took in a Computer Science Masters program?

  - by Bob Dole

  I'm torn between two classes right now for next semester (Software Design and Advanced Computer Graphics). I would enjoy Advanced Computer Graphics more, but I feel the software design class would help me when approaching anything I ever build for the rest of my career. I feel though I could just buy the book (I already have both books actually) of the Software Design class and go through it, if I wanted. But think it would be a bit tougher to pick up the Advanced Computer Graphics class on my own. So do employers look at the graduate classes you've taken to decide if you would be a good fit or not? I think, more importantly, what I'm wanting to know is if I wanted to work for a high-end software company like Apple or Google would a company like that be more impressed by someone that took software engineering classes or hardcore CS classes?

• Solaris 11 Technology Forums, NYC and Boston

  - by dminer

  By now you're certainly aware that we released Solaris 11; I was on vacation during the launch so haven't had time to write any material related to the Solaris 11 installers, but will get to that soon.  Following onto the release, we're scheduling events in various locations around the world to talk about some of the key new features in Solaris 11 in more depth.  In the northeast US, we've scheduled technology forums in New York City on November 29, and Burlington, MA on November 30.  Click on those links to go to the detailed info and registration.  I'll be one of the speakers at both of them, so hope to see you there!

• Clean SOAP Calls from iOS - SudzC

  - by Richard Jones

  This is worth another mention. If you need to call SOAP web-services from iOS or Javascript, and lets face who doesn't. http://SudzC.com really delivers. You give it the URL to you're WSDL file (or upload a file) and it just spits out a ready to go Xcode project. I would point out that to get it to work 100% I changed line 204, in Soap.m (commented out line is old version, mine is below) //if([child respondsToSelector:@selector(name)] && [[child name] isEqual: name]) { if([child respondsToSelector:@selector(name)] && [[child name] hasSuffix: name]) { I consumed a Microsoft Dynamics NAV set of web-service pages no problem (and they tend to be fairly complex WSDL definitions).

• Ubuntu 12.04 wont install on Macbook

  - by user92325

  I've installed Ubuntu on my Macbook before but something went wrong with the updater. So, I had to backup my HDD and format it and reinstall OS X Lion. But here's the thing: Ever since I re-installed my OS I've been trying to get Ubuntu back on the HDD. I partitioned it to 40 GB and set the file system to Ext4. I also recently created a swap partition too and it seems to install correctly. After i installed rEFIt it just has this cute little penguin sitting there. I rebooted and tried to go back to Ubuntu and the penguin still shows up but this time a black screen pops up and it asks me to insert a bootable device and press any key. I'm not sure why this is happening. This is probably the 5th time I've tried to install it. I've even used a different Ubuntu ISO but it still won't boot after the installation.

• Getting Started

  - by andyleonard

  Every once in a while someone asks me, “How does one go from being just-a-developer to presenting at conferences?” When I hear this question, a little voice inside my head asks, “Why are they asking you ?” And then another voice says, “You idiot, it’s because you made that trip from just-a-developer to conference speaker.” So now we have an admission that I hear voices in my head. (Is anyone surprised? I thought not. Moving on…) A disclaimer: what worked for me may not work for you. I can hear you...(read more)

• "A hard disk may be failing" , but no additional info via gdu-notification-deamon (suggestions?)

  - by blunders

  Got this message after logging in: A hard disk may be failing One or more hard disk report health problems. Click the icon to get more information. On WUBI and 10.04, there was no icon to click, and clicking on made the message go away. After rebooting, the message did not display again. I've got everything on all my hard drives in duplicate, so not super worried about a disk failure, though I am wondering why the message had no info on which disk it thought had problems. Suggestions?

• returning null vs returning zero, which would be better?

  - by Dark Star1

  I inherited a project that I am managing and having to maintain pending the redevelopment of the code base. At the moment I am being tasked with adding little feature all over the place and have gotten into the habit of returning null instead of zero in parts of the code where I am working on. The problem is we have a client that is using this code and parts of code that require data from my implemented features recieve a null and dump the stack trace in UI. I would like to avoid this entirely from my input but without the nullPointer exceptions there's the potential that errors would be introduced into the client's data which may go un-noticed. Usually I would have come up with my own error notification system but I have never inherited a project before. so I am unsure whether to continue down this path. I still believe that the stack dump is preferable to un-noticed data corruption/inaccuracies.

• Learning C++ but wanting to develop iOS Apps

  - by DiscreteGenius

  I'm a computer engineering student and taking my second programming class. I'm learning C++ using "C++ Primer Plus" 5th edition by Prata. I want to develop for iOS. I understand the main language for Xcode is Objective-C. Am I hurting myself by learning C++ before any other language (notably before my desired lang Objective-C)? There's got to be a reason the university requires C++ to learn as a basis language. Please offer any helpful guidance or how I should go about this. Thanks//
