• HDMI sound gone, can't figure out how to turn it back on

  - by Oli

  I have had an Acer Revo box as a media centre for a while. I recently installed Ubuntu Server (10.10) on it and polished it up with nodm (one of the most simple ways to launch an X session) and installed boxee. It's been working fine for over a month. It's just running ALSA. I've had problems with PulseAudio/Boxee/HDMI before so I wanted to keep it simple. And that worked. It pushed both PCM and digital (AAC and various Dolby codecs) over HDMI perfectly. But I restarted it the other day after mucking around with some nfs configuration and now there isn't any sound. The hardware is an ION chipset. Nvidia 9400M graphics with Nvidia MCP79/7A audio. One thing I have noticed is there doesn't appear to be any sign of a IEC958 device. A traditional fix in the past for fresh installs has been to load alsamixer, find the IEC device and toggle its mute but I can't. I'm certain this used to represent the HDMI output. It just doesn't seem to exist any more unless I run sudo alsa-utils restart while boxee is running, when I see it in an error message: * Shutting down ALSA... [ OK ] * Setting up ALSA... * warning: 'alsactl restore' failed with error message 'alsactl: set_control:1388: Cannot write control '2:0:0:IEC958 Playback Default:0' : Operation not permitted'... ...done. When nodm (and thus boxee) aren't running, I don't see this error but alsamixer still doesn't show the IEC channel. aplay -l gives: card 0: NVidia [HDA NVidia], device 0: ALC662 rev1 Analog [ALC662 rev1 Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: NVidia [HDA NVidia], device 3: HDMI 0 [HDMI 0] Subdevices: 0/1 Subdevice #0: subdevice #0 Its section in lshw reads: *-multimedia description: Audio device product: MCP79 High Definition Audio vendor: nVidia Corporation physical id: 8 bus info: pci@0000:00:08.0 version: b1 width: 32 bits clock: 66MHz capabilities: pm bus_master cap_list configuration: driver=HDA Intel latency=0 maxlatency=5 mingnt=2 resources: irq:22 memory:fae78000-fae7bfff I was running on the stock PAE kernel but now it's running on 2.6.37.1. I upgraded to see if that fixed things; it didn't. I'm considering a reinstall but I hate doing that because a) there's a bit of custom configuration in getting X and Boxee to start on boot and b) I don't know what the problem is. If I reinstall this time, I'll end up doing that every time the sound breaks. I love Ubuntu but I don't want to install it once a month. Is there any way to forcibly reset all alsa settings and restart from scratch (without doing a reinstall)? Any other tips? If you need more information, just ask.

• Oracle HCM Cloud Customer Q&A with WAXIE Sanitary Supply

  - by HCM-Oracle

  At this year’s Oracle HCM User Group (OHUG) Global conference, we had the opportunity to sit down with Oracle HCM Cloud customers for a short Q&A. We got to hear about what brought them to the OHUG conference, some of the benefits they are receiving from their Oracle HCM Cloud solutions, and advice they would give other businesses looking to move to the cloud.  Below is a discussion we had with Melissa Halverson, Benefits & HRIS Manager at WAXIE Sanitary Supply.  Q: What made you attend the OHUG Global Conference this year? Halverson: The biggest reason is networking. It allows me to connect with others in the Oracle HCM Cloud community. I was able to speak at the HCM Cloud SIG (Special Interest Group) on the first day and share my experiences as well as hear the experiences of other Oracle HCM Cloud users. It also allows me to get face-time with key people within Oracle.  Q: What Oracle HCM solutions are you currently using? Halverson: Global HR, Benefits, Workforce Compensation, and Performance Management. Q: Do you plan to invest further in Oracle HCM? Halverson: Yes, we are interested in Time and Labor. We would also like to get Recruiting at some point in the future. Q: What would you say is the most significant benefit you’ve realized from your use of Oracle HCM solutions? Halverson: First and foremost would be process improvement. Before we had Oracle HCM Cloud we relied on a paper process where something as simple as an employee address change required changes to be made manually in 9 different systems. Obviously that was extremely inefficient, but also increased the likelihood of errors being made.  The other huge benefit we have seen was in making information visible to the people that need it. Prior to implementing Oracle HCM Cloud, it was very difficult for anyone to access and make use of the information in our systems. Now, we can provide this information to those who need it to make better decisions.  Q: What advice would you give an organization looking to move their HR systems to the cloud? Halverson: One thing I think many organizations don't spend enough time doing is thoroughly vetting their implementation partner. I believe you should be vetting your implementation partner as much as you did the system itself. Also, manpower is so important. Involve as large a team as possible because you don’t want to get stuck having too few bodies to help out. And set realistic time frames. Biting off more than you can chew will inevitably result in failure. Having a phased approach is always best rather than trying to do everything at once. Thanks for the tips Melissa. Enjoy the rest of the conference!

• Advanced Record-Level Business Intelligence with Inner Queries

  - by gt0084e1

  While business intelligence is generally applied at an aggregate level to large data sets, it's often useful to provide a more streamlined insight into an individual records or to be able to sort and rank them. For instance, a salesperson looking at a specific customer could benefit from basic stats on that account. A marketer trying to define an ideal customer could pull the top entries and look for insights or patterns. Inner queries let you do sophisticated analysis without the overhead of traditional BI or OLAP technologies like Analysis Services. Example - Order History Constancy Let's assume that management has realized that the best thing for our business is to have customers ordering every month. We'll need to identify and rank customers based on how consistently they buy and when their last purchase was so sales & marketing can respond accordingly. Our current application may not be able to provide this and adding an OLAP server like SSAS may be overkill for our needs. Luckily, SQL Server provides the ability to do relatively sophisticated analytics via inner queries. Here's the kind of output we'd like to see. Creating the Queries Before you create a view, you need to create the SQL query that does the calculations. Here we are calculating the total number of orders as well as the number of months since the last order. These fields might be very useful to sort by but may not be available in the app. This approach provides a very streamlined and high performance method of delivering actionable information without radically changing the application. It's also works very well with self-service reporting tools like Izenda. SELECT CustomerID,CompanyName, ( SELECT COUNT(OrderID) FROM Orders WHERE Orders.CustomerID = Customers.CustomerID ) As Orders, DATEDIFF(mm, ( SELECT Max(OrderDate) FROM Orders WHERE Orders.CustomerID = Customers.CustomerID) ,getdate() ) AS MonthsSinceLastOrder FROM Customers Creating Views To turn this or any query into a view, just put CREATE VIEW AS before it. If you want to change it use the statement ALTER VIEW AS. Creating Computed Columns If you'd prefer not to create a view, inner queries can also be applied by using computed columns. Place you SQL in the (Formula) field of the Computed Column Specification or check out this article here. Advanced Scoring and Ranking One of the best uses for this approach is to score leads based on multiple fields. For instance, you may be in a business where customers that don't order every month require more persistent follow up. You could devise a simple formula that shows the continuity of an account. If they ordered every month since their first order, they would be at 100 indicating that they have been ordering 100% of the time. Here's the query that would calculate that. It uses a few SQL tricks to make this happen. We are extracting the count of unique months and then dividing by the months since initial order. This query will give you the following information which can be used to help sales and marketing now where to focus. You could sort by this percentage to know where to start calling or to find patterns describing your best customers. Number of orders First Order Date Last Order Date Percentage of months order was placed since last order. SELECT CustomerID, (SELECT COUNT(OrderID) FROM Orders WHERE Orders.CustomerID = Customers.CustomerID) As Orders, (SELECT Max(OrderDate) FROM Orders WHERE Orders.CustomerID = Customers.CustomerID) AS LastOrder, (SELECT Min(OrderDate) FROM Orders WHERE Orders.CustomerID = Customers.CustomerID) AS FirstOrder, DATEDIFF(mm,(SELECT Min(OrderDate) FROM Orders WHERE Orders.CustomerID = Customers.CustomerID),getdate()) AS MonthsSinceFirstOrder, 100*(SELECT COUNT(DISTINCT 100*DATEPART(yy,OrderDate) + DATEPART(mm,OrderDate)) FROM Orders WHERE Orders.CustomerID = Customers.CustomerID) / DATEDIFF(mm,(SELECT Min(OrderDate) FROM Orders WHERE Orders.CustomerID = Customers.CustomerID),getdate()) As OrderPercent FROM Customers

• Hijax == sneaky Javascript redirects? Will I get banned from Google?

  - by Chris Jacob

  Question Will I get penalised as "sneaky Javascript redirects" by Google if I have the following Hijax setup (which requires a JavaScript redirect on the page indexed by google). Goal I want to implement Hijax to enable AJAX content to be accessibile to non-JavaScript users and search engine crawlers. Background I'm working on a static file server (GitHub Pages). No server side tricks allowed (so Google's #! "hash bang" solution is not an option). I'm trying to keep my files DRY. I don't want to repeat the common OUTER template in all my files i.e. header, navigation menu, footer, etc They will live in the main index.html Setup the Hijax index.html page contains all OUTER html/css/js... the site's template. index.html has a <div id="content"> which defaults to containing the "homepage" html. index.html has a navigation menu, with a Hijax link to an "about" page. With JavaScript disabled (e.g. crawler) it follows link to /about.html. With JavaScript enabled (e.g. most people) the link updates the url hash fragment to /#about and jQuery replaces the <div id="content"> innerHTML with $("#content").load("about.html #inner-container");. AJAX content about.html does not contain anything extra to try an cloak content for crawlers. about.html file contains enough HTML / CSS / JavaScript to display /about.html as a standalone page with it's own META data... e.g. <html><head><title>About</title>...</head><body></body></html>. about.html has NO OUTER HTML template (i.e. header, navigation menu, footer, etc). about.html <body> contains a <div id="inner-container"> which holds the content that is injected into index.html. about.html has a <noscript> tag as the first child of <body> which explains to non-JavaScript users that they are viewing the about page "inner content" - with a link to navigate to the index.html page to get the full page layout with menu. The (Sneaky?) Redirect Google indexes the /about.html page. However when a person with JavaScript enabled visits that page there is no OUTER html template (e.g. header, navigation menu, footer, etc). So I need to do a JavaScript redirect to get the person over the /#about page (deeplinking to the "about" page "state" in index.html). I'm thinking of doing a "redirect on click or after 10 seconds". The end results is that user ends up on an "enhanced" page back on index.html with all it's OUTER template - but the core "page" content is practically identical. Known issue with inbound links e.g. Share / Bookmarking It seems that if a user shares the URL /#about on their blog, when allocating inbound links to my site Google ignores everything after the # ... it allocates value to the / page - See: http://stackoverflow.com/questions/5028405/hashbang-vs-hijax/5166665#5166665. I can only try an minimise this issue offering "share" buttons on the page with the appropriate urls i.e. /about.html. Duplicate Sorry. I posted this same question over on http://stackoverflow.com/questions/5561686/hijax-sneaky-javascript-redirects-will-i-get-banned-from-google ... then realised it probably belongs more on this Stack Exchange site... Not sure if I should delete the Stack Overflow question? Or just leave it on both sites? Please leave comment.

• Wireframing: A Day In the Life of UX Workshop at Oracle

  - by ultan o'broin

  The Oracle Applications User Experience team's Day in the Life (DITL) of User Experience (UX) event was run in Oracle's Redwood Shores HQ for Oracle Usability Advisory Board (OUAB) members. I was charged with putting together a wireframing session, together with Director of Financial Applications User Experience, Scott Robinson (@scottrobinson). Example of stunning new wireframing visuals we used on the DITL events. We put on a lively show, explaining the basics of wireframing, the concepts, what it is and isn't, considerations on wireframing tool choice, and then imparting some tips and best practices. But the real energy came when the OUAB customers and partners in the room were challenge to do some wireframing of their own. Wireframing is about bringing your business and product use cases to life in real UX visual terms, by creating a low-fidelity drawing to iterate and agree on in advance of prototyping and coding what is to be finally built and rolled out for users. All the best people wireframe. Leonardo da Vinci used "cartoons" on some great works, tracing outlines first and using red ochre or charcoal dropped through holes in the tracing parchment onto the canvas to outline the subject. (Image distributed under Wikimedia commons license) Wireframing an application's user experience design enables you to: Obtain stakeholder buy-in. Enable faster iteration of different designs. Determine the task flow navigation paths (in Oracle Fusion Applications navigation is linked with user roles). Develop a content strategy (readability, search engine optimization (SEO) of content, and so on) Lay out the pages, widgets, groups of features, and so on. Apply usability heuristics early (no replacement for usability testing, but a great way to do some heavy-lifting up front). Decide upstream which functional user experience design patterns to apply (out of the box solutions that expedite productivity). Assess which Oracle Application Development Framework (ADF) or equivalent technology components can be used (again, developer productivity is enhanced downstream). We ran a lively hands-on exercise where teams wireframed a choice of application scenarios using the time-honored tools of pen and paper. Scott worked the floor like a pro, pointing out great use of features, best practices, innovations, and making sure that the whole concept of wireframing, the gestalt, transferred. "We need more buttons!" The cry of the energized. Not quite. The winning wireframe session (online shopping scenario) from the Applications UX DITL event shown. Great fun, great energy, and great teamwork were evident in the room. Naturally, there were prizes for the best wireframe. Well, actually, prizes were handed out to the other attendees too! An exciting, slightly different aspect to delivery of this session made the wireframing event one of the highlights of the day. And definitely, something we will repeat again when we get the chance. Thanks to everyone who attended, contributed, and helped organize.

• Portland Silverlight User Group: WP7 &amp; XNA &ndash; I survived.

  - by George Clingerman

  Last night I gave a talk to the Portland Silverlight User Group. http://www.portlandsilverlight.net/Meetings/Details/15 And I survived (which you should have probably already figured out since you’re reading this post AND that’s what I titled it…) Really though it was a fantastic time and I had a lot of fun! I was a little nervous getting ready for it, but I’m always a little nervous getting ready for things. I had the game all written,  I knew the general flow for what the talk was going to be. I read over Scott Hanselman’s 11 Top Tips for a Successful Technical presentation (which has become something I do EVERY time I’m preparing for a talk). I gave myself a brief list of points I wanted to make sure I covered or worked into the talk. But then I was ready and I waited. I hate the waiting. It makes me nervous. Once I was up in front of the room though with my laptop open and some XNA code in front of me, my nerves go away. Then I’m ready. I know XNA, I love talking about XNA and I love sharing what I know and hearing questions that make me think. And hopefully that came through while I was talking. I had a freaking blast. The swag went quickly (and I was even able to hand out some XNA 2.0 books that have been around forever!) and the pizza was been gobbled down. I started the talk at about 6:10 and managed to cover a very brief intro to programming against the game loop (it’s a different concept and one that seems to trip a lot of people up getting started with game development) and then rolled into making a basic 2D game for Windows Phone 7 using XNA. And I finished the whole thing before 8:30. Wahoo! I’m planning on posting the source code and assets on my site so those should be coming soon. And to make things even better, they recorded the whole thing on video so everyone will get to see me pretend I can speak! Just wait till you hear the new song I wrote for this talk…

• [JAVA]How to make my Oracle update/insert action through JAVA faster?

  - by gunbuster363

  [JAVA]How to make my Oracle update/insert action through JAVA faster? Hi everyone, I am facing a problem in my company that is - our program's speed is not fast enough. To be more specific, we are telecommunication company and this program handle call/internet serfing transaction made by every mobile phone users in our city. Because the amount of download content made by the iphone users is just too much, our program cannot handle them fast enough. The situation is, the amount of transaction made by users are double of the transaction processed by our program. Most of the running time of the program are dominated by DB transactions. I've search through the internet and browsed some sites ( for example: http://www.javaperformancetuning.com/tips/rawtips.shtml ) talking about java performace in DB, but I cannot find a suggestion suitable for us. these advices are not applicable/already used, for instance: 1)Use prepared statements. Use parametrized SQL Already used prepared statement. Each time will use different parameter by clear parameters and set parameters. 2)Tune the SQL to minimize the data returned (e.g. not 'SELECT *'). Sure, already used. 3)Use connection pooling. We hold a single connection during the program's execution. And I doubt that pooling cannot solve the problem because our program act as 1 user, so there are no problem for concurrent access to DB. If anyone of you think pooling is good, please tell me why. Thanks. 4)Try to combine queries and batch updates. Cannot do it. Every query/insert/update is depend on the database's information. For example, we look up the DB for the client's information, if we cannot find his usage, we insert the usage into DB, otherwise we do update. 5)Close resources (Connections, Statements, ResultSets) when finished Sure. 6)Select the fastest JDBC driver. I don't know. I've search on the internet about the type of driver available and I am very confused. We use oracle.jdbc.driver.OracleDriver and we use thin instead of oci, that's all I know. In addition, our program is a two-tier way ( java <- oracle ) 7)turn off auto-commit already done that. Looking forwards to any helps, thank you very much.

• Need help with chronic slow wifi connections

  - by mgeorge

  I have had chronic slow wifi connections on several networks for a while now, I think since my update to 12.04 when it came out.

• So, I though I wanted to learn frontend/web development and break out of my comfort zone...

  - by ripper234

  I've been a backend developer for a long time, and I really swim in that field. C++/C#/Java, databases, NoSql, caching - I feel very much at ease around these platforms/concepts. In the past few years, I started to taste end-to-end web programming, and recently I decided to take a job offer in a front end team developing a large, complex product. I wanted to break out of my comfort zone and become more of an "all around developer". Problem is, I'm getting more and more convinced I don't like it. Things I like about backend programming, and missing in frontend stuff: More interesting problems - When I compare designing a server that handle massive data, to adding another form to a page or changing the validation logic, I find the former a lot more interesting. Refactoring refactoring refactoring - I am addicted to Visual Studio with Resharper, or IntelliJ. I feel very comfortable writing code as it goes without investing too much thought, because I know that with a few clicks I can refactor it into beautiful code. To my knowledge, this doesn't exist at all in javascript. Intellisense and navigation - I hate looking at a bunch of JS code without instantly being able to know what it does. In VS/IntelliJ I can summon the documentation, navigate to the code, climb up inheritance hiererchies ... life is sweet. Auto-completion - Just hit Ctrl-Space on an object to see what you can do with it. Easier to test - With almost any backend feature, I can use TDD to capture the requirements, see a bunch of failing tests, then implement, knowing that if the tests pass I did my job well. With frontend, while tests can help a bit, I find that most of the testing is still manual - fire up that browser and verify the site didn't break. I miss that feeling of "A green CI means everything is well with the world." Now, I've only seriously practiced frontend development for about two months now, so this might seem premature ... but I'm getting a nagging feeling that I should abandon this quest and return to my comfort zone, because, well, it's so comfy and fun. Another point worth mentioning in this context is that while I am learning some frontend tools, a lot of what I'm learning is our company's specific infrastructure, which I'm not sure will be very useful later on in my career. Any suggestions or tips? Do you think I should give frontend programming "a proper chance" of at least six to twelve months before calling it quits? Could all my pains be growing pains, and will they magically disappear as I get more experienced? Or is gaining this perspective is valuable enough, even if plan to do more "backend stuff" later on, that it's worth grinding my teeth and continuing with my learning?

• JavaOne 2012: Nashorn Edition

  - by $utils.escapeXML($entry.author)

  As with my JavaOne 2012: OpenJDK Edition post a while back (now updated to reflect the schedule of the talks), I find it convenient to have my JavaOne schedule ordered by subjects of interest. Beside OpenJDK in all its flavors, another subject I find very exciting is Nashorn. I blogged about the various material on Nashorn in the past, and we interviewed Jim Laskey, the Project Lead on Project Nashorn in the Java Spotlight podcast. So without further ado, here are the JavaOne 2012 talks and BOFs with Nashorn in their title, or abstract:CON5390 - Nashorn: Optimizing JavaScript and Dynamic Language Execution on the JVM - Monday, Oct 1, 8:30 AM - 9:30 AMThere are many implementations of JavaScript, meant to run either on the JVM or standalone as native code. Both approaches have their respective pros and cons. The Oracle Nashorn JavaScript project is based on the former approach. This presentation goes through the performance work that has gone on in Oracle’s Nashorn JavaScript project to date in order to make JavaScript-to-bytecode generation for execution on the JVM feasible. It shows that the new invoke dynamic bytecode gets us part of the way there but may not quite be enough. What other tricks did the Nashorn project use? The presentation also discusses future directions for increased performance for dynamic languages on the JVM, covering proposed enhancements to both the JVM itself and to the bytecode compiler.CON4082 - Nashorn: JavaScript on the JVM - Monday, Oct 1, 3:00 PM - 4:00 PMThe JavaScript programming language has been experiencing a renaissance of late, driven by the interest in HTML5. Nashorn is a JavaScript engine implemented fully in Java on the JVM. It is based on the Da Vinci Machine (JSR 292) and will be available with JDK 8. This session describes the goals of Project Nashorn, gives a top-level view of how it all works, provides the current status, and demonstrates examples of JavaScript and Java working together.BOF4763 - Meet the Nashorn JavaScript Team - Tuesday, Oct 2, 4:30 PM - 5:15 PMCome to this session to meet the Oracle JavaScript (Project Nashorn) language teamBOF6661 - Nashorn, Node, and Java Persistence - Tuesday, Oct 2, 5:30 PM - 6:15 PMWith Project Nashorn, developers will have a full and modern JavaScript engine available on the JVM. In addition, they will have support for running Node applications with Node.jar. This unique combination of capabilities opens the door for best-of-breed applications combining Node with Java SE and Java EE. In this session, you’ll learn about Node.jar and how it can be combined with Java EE components such as EclipseLink JPA for rich Java persistence. You’ll also hear about all of Node.jar’s mapping, caching, querying, performance, and scaling features.CON10657 - The Polyglot Java VM and Java Middleware - Thursday, Oct 4, 12:30 PM - 1:30 PMIn this session, Red Hat and Oracle discuss the impact of polyglot programming from their own unique perspectives, examining non-Java languages that utilize Oracle’s Java HotSpot VM. You’ll hear a discussion of topics relating to Ruby, Lisp, and Clojure and the intersection of other languages where they may touch upon individual frameworks and projects, and you’ll get perspectives on JavaScript via the Nashorn Project, an upcoming JavaScript engine, developed fully in Java.CON5251 - Putting the Metaobject Protocol to Work: Nashorn’s Java Bindings - Thursday, Oct 4, 2:00 PM - 3:00 PMProject Nashorn is Oracle’s new JavaScript runtime in Java 8. Being a JavaScript runtime running on the JVM, it provides integration with the underlying runtime by enabling JavaScript objects to manipulate Java objects, implement Java interfaces, and extend Java classes. Nashorn is invokedynamic-based, and for its Java integration, it does away with the concept of wrapper objects in favor of direct virtual machine linking to Java objects’ methods provided by a metaobject protocol, providing much higher performance than what could be expected from a scripting runtime. This session looks at the details of the integration, a topic of interest to other language implementers on the JVM and a wider audience of developers who want to understand how Nashorn works.That's 6 sessions tooting the Nashorn this year at JavaOne, up from 2 last year.

• Can't boot Ubuntu 12.10 graphics problem

  - by Frantumn

  I can't boot since installing Ubuntu 12.10 When I try to run Ubuntu My computer never gets to the Ubuntu screen with the loading dots. I tried to run in recovery mode with safe graphics (failsafex) When I do this a message pops up saying "the system is running in low graphics mode", If I click okay I am asked what would I like to do and am given four options. I tried running low graphics for one session and then a message appears with a progress bar and says standby one minute while the display restarts. The progress bar never moves and if I click okay the whole process just restarts. I Don't know what to do from here I can't get into the OS. I'm not sure whether the problem is related to compatibility with my laptop monitor or my graphic card nvidia360m I had to install using a safe graphics mode. To learn about how I installed see this link. This link also has information on my computer hardware. Can't install Ubuntu since 10.10 ----UPDATE--- I was able to get into a desktop environment By installing Nvidia-current however it is messy. I have a screen and I am able to see my desktop however there is no unity bar and none of the keyboard controls work. I can right click and create a folder on the desktop and then I can see inside that folder in a traditional browser window. There is still no top menu or unity bar. When I boot normally I don't get into the desktop environment and I get this message in tty 'GPU lockup switching to software FBCON' Okay, I've played around with tips the pages from comments. I've been able to consistantly get into a safemode desktop environment using the xorg & nouveau drivers. I've tried switching between the 5 different options in the Additional Drivers tab in Software Sources. The nVidia (proprietary, tested) driver gets beyond the GPU lockup on a normal boot and actually gets into a Desktop. The issue is then that there is no Unity bar, or top screen menu bar and the resolution is very low. I've tried switching to the (prop, tested) driver and then reinstalling Unity and Ubuntu-Desktop but that didn't work either.

• Moving abroad - Relocation advice

  - by Tim Koekkoek

  Oracle offers graduates from different European countries the opportunity to start their career abroad. Some already have experience with living abroad as they have done an exchange semester or internship in another county, for others it is the first time they will move abroad. Rui started in October 2011 as a Business Development Consultant in Dublin and moved from Portugal to Dublin, Ireland to start his career. For those planning to leave their home country and who desire to work abroad, he will share some tips and tricks in this article. When you’re faced with an opportunity like this, there are lots of things that will come to your mind. Sometimes it can be either very exciting, or even stressful. 1. First of all, try to relax. If you are certain you are moving abroad, all you need to do is some research about the country where you’re going to live, get to know its culture (gastronomy, important dates and events, its economy and effective ways to keep you in touch with your family and friends – such as mobile companies and Internet services), and start to understand the best locations (with good access) you could/should live in are. Don’t forget that initially you can be limited by transport and therefore it is important to explore the ideal places for you. During this time, Oracle provides everything you’ll need (papers, documents, etc.) to cross borders. 2. When you arrive, you understand that you are in a new country, in a new place, where all things (or most) are unknown to you. Before you panic, try to see it as a new challenge where new opportunities will come. Sometimes, it’s not easy I know, but the very best a new place has to give to you, is the opportunity to understand a new culture, get to know other people, other ways of working, and grow both as a person and professionally.

• How to display image in second layer in Cocos2d

  - by PeterK

  I am very new at Cocos2d and is testing to displaying an image over the "Hello World" text on a second layer and need help to get it work. I guess it is some basic stuff here and appreciate any tips etc. with this. I know that if i put the display-code (myLayer1) in the "init" it work or do the call [self goHere] from the "init" in myLayer1 it works but i want to call the "goHere" directly. I have the following code: HelloWorld.m: #import "HelloWorldLayer.h" #import "myLayer1.h" // HelloWorldLayer implementation @implementation HelloWorldLayer +(CCScene *) scene { // 'scene' is an autorelease object. CCScene *scene = [CCScene node]; // 'layer' is an autorelease object. HelloWorldLayer *layer = [HelloWorldLayer node]; myLayer1 *layer1 = [myLayer1 node]; // add layer as a child to scene [scene addChild: layer]; [scene addChild: layer1]; // return the scene return scene; } // on "init" you need to initialize your instance -(id) init { // always call "super" init // Apple recommends to re-assign "self" with the "super" return value if( (self=[super init])) { // create and initialize a Label CCLabelTTF *label = [CCLabelTTF labelWithString:@"Hello World" fontName:@"Marker Felt" fontSize:64]; // ask director the the window size CGSize size = [[CCDirector sharedDirector] winSize]; // position the label on the center of the screen label.position = ccp( size.width /2 , size.height/2 ); // add the label as a child to this Layer [self addChild: label]; myLayer1 *a1 = [myLayer1 new]; [a1 goHere]; [myLayer1 release]; } return self; } myLayer1.m: #import "myLayer1.h" @implementation myLayer1 -(void)goHere { NSLog(@">>>>goHere<<<<"); CGSize size = [[CCDirector sharedDirector] winSize]; CCSprite *vv = [CCSprite spriteWithFile:@"hand.png"]; vv.position = ccp( size.width /2 , size.height/2 ); [self addChild:vv z:3]; } -(id) init { // always call "super" init // Apple recommends to re-assign "self" with the "super" return value if( (self=[super init])) { } return self; } @end

• "Untrusted packages could compromise your system's security." appears while trying to install anything

  - by maria

  Hi I've freshly installed Ubuntu 10.4 on a new computer. I'm trying to install on it application I need (my old computer is broken and I have to send it to the service). I've managed to install texlive and than I can't install anything else. All software I want to have is what I have succesfuly installed on my old computer (with the same version of Ubuntu), so I don't understand, why terminal says (sorry, the terminal talks half English, half Polish, but I hope it's enough): maria@marysia-ubuntu:~$ sudo aptitude install emacs Czytanie list pakietów... Gotowe Budowanie drzewa zaleznosci Odczyt informacji o stanie... Gotowe Reading extended state information Initializing package states... Gotowe The following NEW packages will be installed: emacs emacs23{a} emacs23-bin-common{a} emacs23-common{a} emacsen-common{a} 0 packages upgraded, 5 newly installed, 0 to remove and 0 not upgraded. Need to get 23,9MB of archives. After unpacking 73,8MB will be used. Do you want to continue? [Y/n/?] Y WARNING: untrusted versions of the following packages will be installed! Untrusted packages could compromise your system's security. You should only proceed with the installation if you are certain that this is what you want to do. emacs emacs23-bin-common emacsen-common emacs23-common emacs23 Do you want to ignore this warning and proceed anyway? To continue, enter "Yes"; to abort, enter "No" I was trying to install other editors as well, with the same result. As I decided that I might be sure that I know the package I want to install is secure, finaly I've entered "Yes". The installation ended succesfuly, but editor don't understand any .tex file (.tex files are for sure fine): this is pdfTeX, Version 3.1415926-1.40.10 (TeX Live 2009/Debian) restricted \write18 enabled. entering extended mode (./Szarfi.tex ! Undefined control sequence. l.2 \documentclass {book} ? What's more, I've realised that in Synaptic Manager there is no package which would be marked as supported by Canonical... Any tips? Thanks in advance
