  • Warning: E-Business Suite Issues with Sun JRE 1.6.0_20

    - by Steven Chan
    My colleagues in the Java division have just released Java Runtime Engine (JRE) 1.6.0_20 today.  See the 1.6.0_20 Update Release Notes for details about what has been changed in this release.The issues reported in the following articles still also apply to JRE 1.6.0_20:Warning: E-Business Suite Issues with Sun JRE 1.6.0_19Warning: E-Business Suite Issues with Sun JRE 1.6.0_18Depending upon your security and Java deployment policies for your end-user desktops, you may need to update your users to this JRE release.  Unfortunately, you will have to balance your need for the fixes in JRE 1.6.0_20 against the impact of the open EBS compatibility issues reported with 6u18, 6u19, 6u20.We're working closely with the Sun JRE team to get the open EBS compatibility issues resolved as quickly as possible.  This is being worked at the top priority.  Please monitor this blog for updates.

  • are keywords in URLs good SEO or needlessly redundant?

    - by Blazemonger
    A coworker and I are locked in a debate over the value of SEO keywords in the URL of a page. She wants to change all the filenames of the HTML pages of a fencing company so they look like residential-home-chicago.html, contact-chicago-contractor.html, and so on. She is convinced that because Google highlights keywords in URLS in search results, that means that putting keywords here is more valuable. My position is that these do not improve SEO, since Google doesn't seem to give keywords in the URL any more weight than keywords in the body of the page, and might even give them less weight. In the meantime, they make it harder for me to find the pages I want when its time to edit them, and the site as a whole looks cheap and spammy. Google's own SEO guide suggests to me that yes, keywords in URLs are useful, but not superior, and that they are more useful for human readability than search engine rankings. I'm looking for authoritative sources that support either position, not blog articles from SEO optimization companies trying to promote themselves.

  • Java 7 Adoption at 79%

    - by Henrik Stahl
    According to a recent blog post from the cloud hosting company Jelastic, Java 7 adoption on their platform is now at 79%. While this is a single data point and should not be read too broadly, it does match other indicators we have that Java 7 is picking up, such as uptake among Oracle middleware customers, download statistics and online activity. The spike in adoption in April coincided with the release of JDK 7 Update 4. This is in line with our expectations since that release added Mac OS X support as well as java.com moving to Java 7 as the default download for end-users; two events that marked the maturity of Java 7 to the community. Since the original release of Java 7, Oracle has shipped 7 update releases, added ports to Mac OSX and Linux/ARM and expanded JavaFX to all common desktop platforms.

  • What do I need to get a job with a major game company?

    - by MahanGM
    I've been recently working with DirectX and getting familiar with game engines, sub-systems and have done game development for the last 5 years. I have a real question for those whom have worked in larger game making companies before. How is it possible to get to into these big game creators such as Ubisoft, Infinity Ward or EA. I'm not a beginner in my field and I'm going to produce a real nice 2D platform with my team this year, which is the result of 5 years 2D game creation experience. I'm working with prepared engines such as Unity3D or Game Maker software and using .Net with C# to write many tools for our production and proceeding in my way but never had a real engine programming experience 'till now. I'm now reading good books around this topic but I wanted to know: Is it possible to become an employee in big game company by just reading books? I mean beside having an active mind and new ideas and being a solution solver.

  • Country specific SEO

    - by John
    I have a wordpress site which is located at a .com address. The site is a simple 4 page personal site with my academic credentials, publications and a health blog that I started. I have done quite a bit of seo and I rank pretty high for the keywords i want on google.co.uk. However, I do not rank at all on google.com.mt which is the Malta specific search. I have therefore just bought the .com.mt domain and pointed the DNS nameservers to my current host provider and redirected it to the .com address. My goal is to make sure I don't screw up my google.co.uk search ranking, while starting to rank on google.com.mt I'm I doing the right thing or do you have any suggestions??

  • Is dynamic casting Entities A good design?

    - by Milo
    For my game, Everything inherits from Entity, then other things like Player, PhysicsObject, etc, inherit from Entity. The physics engine sends collision callbacks which has an Entity* to the B that A collided on. Then, lets say A is a Bullet, A tries to cast the entity as a player, if it succeeds, it reduces the player's health. Is this a good design? The problem I have with a message system is that I'd need messages for everything, like: entity.sendMessage(SET_PLAYER_HEALTH,16); So that's why I think casting is cleaner.

  • Problems with opening CHM Help files from Network or Internet

    - by Rick Strahl
    As a publisher of a Help Creation tool called Html Help Help Builder, I’ve seen a lot of problems with help files that won't properly display actual topic content and displays an error message for topics instead. Here’s the scenario: You go ahead and happily build your fancy, schmanzy Help File for your application and deploy it to your customer. Or alternately you've created a help file and you let your customers download them off the Internet directly or in a zip file. The customer downloads the file, opens the zip file and copies the help file contained in the zip file to disk. She then opens the help file and finds the following unfortunate result:     The help file  comes up with all topics in the tree on the left, but a Navigation to the WebPage was cancelled or Operation Aborted error in the Help Viewer's content window whenever you try to open a topic. The CHM file obviously opened since the topic list is there, but the Help Viewer refuses to display the content. Looks like a broken help file, right? But it's not - it's merely a Windows security 'feature' that tries to be overly helpful in protecting you. The reason this happens is because files downloaded off the Internet - including ZIP files and CHM files contained in those zip files - are marked as as coming from the Internet and so can potentially be malicious, so do not get browsing rights on the local machine – they can’t access local Web content, which is exactly what help topics are. If you look at the URL of a help topic you see something like this:   mk:@MSITStore:C:\wwapps\wwIPStuff\wwipstuff.chm::/indexpage.htm which points at a special Microsoft Url Moniker that in turn points the CHM file and a relative path within that HTML help file. Try pasting a URL like this into Internet Explorer and you'll see the help topic pop up in your browser (along with a warning most likely). Although the URL looks weird this still equates to a call to the local computer zone, the same as if you had navigated to a local file in IE which by default is not allowed.  Unfortunately, unlike Internet Explorer where you have the option of clicking a security toolbar, the CHM viewer simply refuses to load the page and you get an error page as shown above. How to Fix This - Unblock the Help File There's a workaround that lets you explicitly 'unblock' a CHM help file. To do this: Open Windows Explorer Find your CHM file Right click and select Properties Click the Unblock button on the General tab Here's what the dialog looks like:   Clicking the Unblock button basically, tells Windows that you approve this Help File and allows topics to be viewed.   Is this insecure? Not unless you're running a really old Version of Windows (XP pre-SP1). In recent versions of Windows Internet Explorer pops up various security dialogs or fires script errors when potentially malicious operations are accessed (like loading Active Controls), so it's relatively safe to run local content in the CHM viewer. Since most help files don't contain script or only load script that runs pure JavaScript access web resources this works fine without issues. How to avoid this Problem As an application developer there's a simple solution around this problem: Always install your Help Files with an Installer. The above security warning pop up because Windows can't validate the source of the CHM file. However, if the help file is installed as part of an installation the installation and all files associated with that installation including the help file are trusted. A fully installed Help File of an application works just fine because it is trusted by Windows. Summary It's annoying as all hell that this sort of obtrusive marking is necessary, but it's admittedly a necessary evil because of Microsoft's use of the insecure Internet Explorer engine that drives the CHM Html Engine's topic viewer. Because help files are viewing local content and script is allowed to execute in CHM files there's potential for malicious code hiding in CHM files and the above precautions are supposed to avoid any issues. © Rick Strahl, West Wind Technologies, 2005-2012 Tweet !function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0];if(!d.getElementById(id)){js=d.createElement(s);js.id=id;js.src="//platform.twitter.com/widgets.js";fjs.parentNode.insertBefore(js,fjs);}}(document,"script","twitter-wjs"); (function() { var po = document.createElement('script'); po.type = 'text/javascript'; po.async = true; po.src = 'https://apis.google.com/js/plusone.js'; var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(po, s); })();

  • Few specific questions on how games are developed

    - by russ
    When it comes to programming games from the old school sega games like sonic to indie games or angry birds or even to more advance games like Diablo, how exactly is level design done? As in, are the levels sometimes designed straight out of code in an IDE? Or do they create a visual level design editor where things can be placed at the click of a mouse button? I'm imagining old school games or very simple ones like indies are done via code, where extremely complicated ones require a visual editor. Is this correct? Also, when it comes to libraries like SDL or XNA, how often are these used rather than just utilizing OpenGL or DirectX? What about creating your own game engine vs utilizing one already made? Do most use already built engines? This question is directed toward the whole gaming spectrum of indie/big game development. Thanks.

  • 2.5D action RPG game

    - by Phorden
    I want to make a 2.5D action RPG game in the next say five years. I need to learn a language first and I have started with C#. I haven't gotten too far into learning it and I would like advice on the best way to approach making a game like this in the long run. Work with XNA studios or stop and learn C++ and UDK? Or maybe there is another good way to approach this. I want to learn programming, so just using a visual editor without learning to code is not the way I want to go. I also don't want to write my game engine from scratch. I'm all ears for advice.

  • Custom Themes Introduced in Gmail

    - by Rekha
    As we all know, Google Team introduced a number of HD themes last November. Now they are giving us an option of customizing our own background. We can put in our own images, select from our Google+ photos or just paste any image URL. Or we can browse the Featured Photos section to find the image that we like. They are introducing custom themes with two options, Light and Dark. In the Featured tab, we can simply search for specific kind of pictures like “hdr scenery” or “bokeh wallpaper” and so on. We can easily maintain our personal or work accounts with different background images that suites the best. The company announced this information in their blog today.

  • A New Experience

    - by Calum
    So a couple of weeks ago, after a fraction over 12 years, I bade farewell to the Solaris Desktop team to join the team whose blog you're reading now: Oracle's Systems Experience Design team, known internally as sxDesign, which has a wider but still largely Solaris-focused usability remit.1 There's been a good deal of overlap and collaboration between the two teams over the years anyway, so it's not exactly a step into the unknown. The elders among you might remember a GNOME 1.4 usability study I presented at GUADEC in 2001, for example, which was primarily the handiwork of a previous incarnation of sxDesign… I pretty much just turned up at the end to steal the glory for the Desktop team. In your face, people I'm going to be working with now!2 1 A move I was first approached about making in about 2003, I think… who says I'm rubbish at making snap decisions? 2 I'm not really. They all left years ago.

  • Is it true that the Google Spider gives the most relevance of a search result to the first 68 characters of the <title>?

    - by leeand00
    I am reading documentation about my CMS and it states that an HTML page <title> tag is really important in SEO. It states that the Google Spider gives the most relevance to the first 68 characters of a site title. (68 characters being the number of characters that Google will display in it's search engine result pages,) Can anyone verify this is still true? I read in The Information Diet that content farms were getting too good at gaming Google's algorithm for collecting and posting SERPs and so google had to change the search algorithm.

This month’s feature is a follow-up from last month’s Global Perspective note from a well known ACE Director based in EMEA. My first contribution to this blog was before Oracle Open World and I was quite excited about where this initiative would take me in my understanding of the value of Oracle Fusion Middleware. Rimi Bewtra from the Oracle AppAdvantage team came as promised to the Oracle ACE Director briefings and explained what this initiative was all about and I then asked the directors to take part in the new survey. The story was really well received and then at the SOA advisory board that many of these ACE Directors already take part in there was a further discussion on how this initiative will help customers understand the benefits of adoption. A few days later Rick Beers launched the program at a lunch of invited customer executives which included one from Pella who talked about their projects (a quick recap on that here). I wasn’t able to stay for the whole event but what really interested me was that these executives who understood the technology but where looking for how they could use them to drive their businesses. Lots of ideas were bubbling up in my head about how we can use this in user groups to help our members, and the timing was fantastic as just three weeks later we had UKOUG_Apps13, our flagship Applications conference in the UK. We had independently working with Oracle marketing in the UK on an initiative called Apps Transformation to help our members look beyond just the application they use today. We have had a Fusion community page but felt the options open are now much wider than Fusion Applications, there are acquired applications, social, mobility and of course the underlying technology, Oracle Fusion Middleware. I was really pleased to be allowed to give the Oracle AppAdvantage story as a session in our conference and we are planning a special Apps Transformation event in March where I hope the Oracle AppAdvantage team will take part and we will have the results of the survey to discuss. But, life also came full circle for me. In my first post, I talked about Andrew Sutherland and his original theory that Oracle Fusion Middleware adoption had technical drivers. Well, Andrew was a speaker at our event and he gave a potted, tech-talk free update on Oracle Open World. Andrew talked about the Prevailing Technology Winds, and what is driving this today and he talked about that in the past it was the move from simply automating processes (ERP etc), through the altering of those processes (SOA) and onto consolidation. The next drivers are around the need to predict, both faster and more accurately; how to better exploit the information that we have available. He went on to talk about The Nexus of Forces: Social, Mobile, Cloud and Information – harnessing these forces of change with Oracle technology. Gartner really likes this concept and if you want to know more you can get their paper here. All this has made me think, and I hope it will make you too. Technology can help us drive our businesses better and understanding your needs can be the first step on your journey, which was the theme of our event in the UK. I spoke to a number of the delegates and I hope to share some of their stories in later posts. If you have a story to share, the survey is at: https://www.surveymonkey.com/s/P335DD3 About the Author: Debra Lilley, Fujitsu Fusion Champion, UKOUG Board Member, Fusion User Experience Advocate and ACE Director.

  • 2D XNA Tile Based Lighting. Ideas and Methods

    - by Twitchy
    I am currently working on developing a 2D tile based game, similar to the game 'Terraria'. We have the base tile and chunk engine working and are now looking to implement lighting. Instead of the tile based lighting that terraria uses, I want to implement point lights for torches, etc. I have seen Catalin Zima’s shader based shadows, and this would be perfect for the torches (point lights). My problem here is that the tiles on the surface of the world need to be illuminated, doing this by a big point light is firstly extremely expensive, but also doesn't look right. What I need help with (overall) is... To have a surface that is illuminated regardless of torches, etc. To also have point lights, or smooth tile lighting similar to Catalin Zima’s shader based shadows. Looking forward to your replies. Any ideas are appreciated.

  • What is the difference between Output Text and Output Text (Active)?

    - by [email protected]
    When building an ADF Faces application in JDeveloper, you might have noticed that in the Component Palette there is an option for both "Output Text" as well as "Output Text (Active)".   Why do we have both of these options?Under the covers, there are actually two tags, af:outputText and af:activeOutputText.  Similarly, there is an active version of af:image, namely af:activeImage, and an active version of af:commandToolbarButton, af:activeCommandToolbarButton.In the vast majority of cases, developers should use the non-active version of the components.   The active version of the components are there to support specific usecases around Server Side Push using the Active Data Service feature.  Most of our customers don't use Server Side Push, and hence do not need the active version of the components.  You can learn more about Server Side Push with ADF Active Data Service in this blog.By using the active version of af:outputText, af:image or af:commandToolbarButton when you don't need to, you are taking a performance hit that is unnecessary.

  • Is there any reason to allow Yahoo! Slurp to crawl my site?

    - by James Skemp
    I thought a year or more ago Yahoo! would be using another search engine for results, and no longer using their own Slurp bot. However, a couple of the sites I manage Yahoo! Slurp continues to crawl pages, and seems to ignore the Gone status code when returned (as it keeps coming back). Is there any reason why I wouldn't want to block Yahoo! Slurp via robots.txt or by IP (since it tends to ignore robots.txt in some cases anyways)? I've confirmed that when the bot does hit it is from Yahoo! IPs, so I believe this is a legit instance of the bot. Is Yahoo Search the same as Bing Search now? is a related question, but I don't think it completely answers whether one should add a new block of the bot.

  • What datastructure would you use for a collision-detection in a tilemap?

    - by Solom
    Currently I save those blocks in my map that could be colliding with the player in a HashMap (Vector2, Block). So the Vector2 represents the coordinates of the blog. Whenever the player moves I then iterate over all these Blocks (that are in a specific range around the player) and check if a collision happened. This was my first rough idea on how to implement the collision-detection. Currently if the player moves I put more and more blocks in the HashMap until a specific "upper bound", then I clear it and start over. I was fully aware that it was not the brightest solution for the problem, but as said, it was a rough first implementation (I'm still learning a lot about game-design and the data-structure). What data-structure would you use to save the Blocks? I thought about a Queue or even a Stack, but I'm not sure, hence I ask.
