  - by Ruma Sanyal

  “We selected Oracle Fusion Middleware for its superior local support, higher performance, availability, reliability, and flexible enterprise architecture to cost-effectively integrate with existing Oracle applications", said Mr. C.W. Miao, Head of Information Technology, Hong Kong Housing Society in a press release today. To address the challenge of frequent downtime during peak periods and increasing cost in maintaining its legacy systems, Hong Kong Housing Society replaced its legacy systems with Oracle's WebLogic Suite, BPM Suite, and the ADF Framework. The Fusion Middleware solutions provide Hong Kong Housing Society with a flexible, reliable and cost-effective enterprise architecture that enables integration with existing Oracle applications including JD Edwards EnterpriseOne and PeopleSoft. The cost savings and performance results clearly demonstrate significant benefits. Read the PR for complete details.

• HLSL problem with divide by homogeneous component

  - by Berend

  When I try to divide my position.z by my position.w in HLSL I get as result always 1.0f or higher. Is this a common problem for some reason? When I divide my position.x or y by the w this works fine. But the divide for the z gives a wrong result. I use the view matrix for my camera and the projection matrix as i use it in the game because I want to create a depthmap from the cameraposition. Can anybody explain what I'm doing wrong? Do I need another view matrix?

• Is it good to buy multiple domains for competitive reasons?

  - by lowestofthekeys

  I am attempting to convince the higher ups at my company that spending $55 to renew one domain for a year is bad when they end up having 3-4 domains names for one website. They're reasoning for doing so is to keep these domains names out of the hands of the competition. For example, the company name is Pie Consulting & Engineering. They want to buy up pieforensicconsulting.com to keep it out of the hands of a competitor (we also do forensic engineering). Could a competitor use that domain in any kind of diabolical way? I mean I figure if someone is typing in pieforensiconsulting into the url field, they know what they're looking for and if it redirects to another company, they're not just going to stay on the site.

• nVidia GeForce Go 7600? can it ever run unity?

  - by Khaled Musleh

  my laptop Toshiba Qosmio G30 has nVidia GeForce Go 7600 card and it suppose to support 3D . i run unity 2d now . I run 12.04 and the graphic driver is--VESA: G73 Board - toshg73m-- by UBUNTU. when i run /usr/lib/nux/unity_support_test -p then i get this list Not software rendered: no Not blacklisted: yes GLX fbconfig: yes GLX texture from pixmap: yes GL npot or rect textures: yes GL vertex program: yes GL fragment program: yes GL vertex buffer object: yes GL framebuffer object: yes GL version is 1.4+: yes Unity 3D supported: no the card is not blacklisted but a similar one with GT is! Do you think that there is a chance the laptop can run the unity 3d? and may be i could change the resolution of the screen to a higher one too! I tried all the nvidia drivers provided but none works (except 96 in ubuntu 12.04 ). i get a black screen or terminal screen. best wishes to all

• First languages with generic programming support

  - by oluies

  Which was the first language with generic programming support, and what was the first major staticly typed language (widely used) with generics support. Generics implement the concept of parameterized types to allow for multiple types. The term generic means "pertaining to or appropriate to large groups of classes." I have seen the following mentions of "first": First-order parametric polymorphism is now a standard element of statically typed programming languages. Starting with System F [20,42] and functional programming lan- guages, the constructs have found their way into mainstream languages such as Java and C#. In these languages, first-order parametric polymorphism is usually called generics. From "Generics of a Higher Kind", Adriaan Moors, Frank Piessens, and Martin Odersky Generic programming is a style of computer programming in which algorithms are written in terms of to-be-specified-later types that are then instantiated when needed for specific types provided as parameters. This approach, pioneered by Ada in 1983 From Wikipedia Generic Programming

• Actor library / framework for C++

  - by Giorgio

  In the C++ project I am working for we would like to use something like Scala actors and remote actors (see e.g. this tutorial). Being able to use remote actors (actors living in different processes, possibly on different machines and communicating via TCP/IP) has higher priority for us because we have an application consisting of several processes deployed on different machines. Being able to use several actors living in the same process (possibly different threads) is also interesting, but has lower priority for the moment. On wikipedia I have found some links to actor libraries for C++ and I have started to look at Theron. Before I dive too deep into the details and build an extended example with Theron, I wanted to ask if anybody has experience with any of these libraries and which one they would recommend.

• Are there well-known examples of web products that were killed by slow service?

  - by Jeremy Wadhams

  It's a basic tenet of UX design that users prefer fast pages. http://www.useit.com/alertbox/response-times.html http://www.nytimes.com/2012/03/01/technology/impatient-web-users-flee-slow-loading-sites.html?pagewanted=all It's supposedly even baked into Google's ranking algorithm now: fast sites rank higher, all else being equal. But are there well known examples of web services where the popular narrative is "it was great, but it was so slow people took their money elsewhere"? I can pretty easily think of example problems with scale (Twitter's fail whale) or reliability (Netflix and Pinterest outages caused by a single datacenter in a storm). But can (lack of) speed really kill?

• Apple Cinema Display 23" and grub

  - by Joshua Pruitt

  As per the title, I'm running my display on an older 23" Apple Cinema Display (because I still love it, darn it). I'm pushing it with an ATI Radeon DVI dual-link PCIe card. It works just fine, except GRUB doesn't seem able to push out the 1920x1200 pixel resolution needed in order to show me a boot menu! So..., I keep a smaller second monitor connected as the primary display so that I can see the boot menu and boot the system (I don't use that display once booted). This is a goofy work-around, and I'd like to just use my single display exclusively to boot the machine. I found some grub codes for higher resolutions, but not for 1920x1200. Is it capable of this? Did I just miss it? Thanks in advance!!!

• At which architecture level are you running BDD tests (e.g. Cucumber)

  - by Pete

  I have in the last year gotten quite fond of using SpecFlow (which is a .NET port of Cucumber) I have used it both to test a ASP.NET MVC application at the web layer, i.e. using browser automation, but also at the controller layer. The first gives me a higher confidence in the correctness of the application, because JavaScript is tested, and improper controller configuration is also caught. But those tests are slower to execute, and more complex to implement, than those just testing on the controller layer. My tests are full functional tests, i.e. they exercise all layers of the application, all the way down to the database. So the first thing before any scenario is that the database is cleared of data, allowing the test to assume that only data specified in the "Given" block exists. Then I see example on how to use it, where they test just exercise the model layer. So what are your experiences with these tools? Which layer of the application do you test?

• Very few visitors on Analytics: incorrect setting?

  - by Akaban

  it's quite a long time Analytics is making me crazy: I have a 2 years old website, started with Aruba (an Italian provider) and then transfered on Hostgator. It's a blog Wordpress + MyBB forum, and on both the platforms I've the Analytics code in the footer. The problem is that the stats on Analytics are simply ridiculous compared to the numbers reported by the Aruba (before) and Hostgator (then). I think that the numbers of Aruba/Hostgator are correct, simply because just the daily users connected on the forum is higher than the Analytics numbers. I know it's a really confused request, but maybe you can help me to understand what's the problem.

• What is the difference between debugging and testing?

  - by persepolis

  Introduction To Software Testing (Ammann & Offutt) mentions on p.32 a 5-level testing maturity model: Level 0 There’s no difference between testing and debugging. Level 1 The purpose of testing is to show that the software works. Level 2 The purpose of testing is to show that the software doesn’t work. Level 3 The purpose of testing is not to prove anything specific, but to reduce the risk of using the software. Level 4 Testing is a mental discipline that helps all IT professionals develop higher quality software. Although they don't go into much further detail. What are the differences between debugging and testing?

• Does a longer registration length/period for a domain name improve its SEO and search ranking?

  - by Cupcake

  While I was renewing a domain of mine with a well-known domain registrar, the support person who was on call with me said that I'd improve the SEO ranking of my domain if I increased the registration length from 1 year to 5 years instead. The explanation that he gave me was something along the lines that a search engine like Google doesn't like to send users to domains and businesses that may no longer exist, and that by registering my domain for 5 years instead of just 1, Google would have higher confidence that I'm serious about keeping my business around for the long-term. Needless to say, I was quite skeptical. Does the registration/renewal length of a domain name affect its SEO and search result ranking for search engines such as Google?

• How to add a link group to update-alternatives?

  - by Kurtosis

  Is it possible to add a custom link group to update-alternatives that is not already there by default? For example, I want to add Scala and all its supporting binaries as a link group 'scala'. I'm trying using this script, but keep getting the error: update-alternatives: error: unknown argument `' I'm not sure what that means, but after troubleshooting the script a bit with no luck, I'm wondering if update-alternatives has a hard-coded list of link groups, that can't be added to, and that doesn't include scala. PS - any chance someone with higher karma can create an update-alternatives tag? Seems this topic gets a decent number of questions, but no tag for it.

• Which specific practices could be called "software craftsmanship" rather than "software engineering"?

  - by FinnNk

  Although not a new idea there seems to have been a big increase in the interest in software craftsmanship over the last couple of years (notably the often recommended book Clean Code's full title is Clean Code: A Handbook of Agile Software Craftsmanship). Personally I see software craftsmanship as good software engineering with an added interest in ensuring that the end result is a joy to work with (both as an end user and as someone maintaining that software) - and also that its focus is more at the coding level of things than the higher level process things. To draw an analogy - there were lots of buildings constructed in the 50s and 60s in a very modern style which took very little account of the people who would be living in them or how those buildings would age over time. Many of those buildings rapidly developed into slums or have been demolished long before their expected lifespans. I'm sure most developers with a few years under their belts will have experienced similar codebases. What are the specific things that a software craftsman might do that a software engineer (possibly a bad one) might not?

• Why is Cocoa using an old version of Unicode? [closed]

  - by Randy Marsh

  While I was searching for something in the Apple docs, I stumble on this: illegalCharacterSet Returns a character set containing values in the category of Non-Characters or that have not yet been defined in version 3.2 of the Unicode standard. On the Unicode website, I find that the latest version is 6.1.0. That's a lot of major versions higher than what Cocoa supports. Does somebody know why Apple doesn't upgrade their framework? My more important question is: Are there problems for not doing having support for Unicode 3.2+? Will I have problems reading Unicode files created on other systems with a more recent version of Unicode?

• The Ubuntu Advantage Service right for my non-profit?

  - by Robert

  My small 5 computer office currently runs on Ubuntu. 2 of the desktops run Windows7 in Sun Virtualbox software, and are used for Quickbooks. I am going off to college, and I am looking for a paid tech support solution to replace my IT position. I have an approx $300/mth budget, and I am wiling to discuss higher rates. Everyone in the office is currently comfortable with regular desktop usage, but I am handling all of the software installation and updates. I was hoping to get a total support package for all of their tech related questions, but I cannot find any services which will support linux. Is the Ubuntu Advantage Service something which can take my place? They would mostly need network help, printer help, and an occasional software compatibly troubleshooting session. If this is not a solution, does anyone know of a tech support forum/hotline which would cover all of this? Thank you for reading.

• Is there now any way to convert mp3 files to m4a or aac 192kbit?

  - by piedro

  Since about two years now I am trying to find a way to convert high quality mp3 files to m4a or aac files with a fixed bitrate 192k. Please don't suggest using another format - i thought this through as far as it goes. The problem here is: ffmpeg obvioulsy can't convert to a higher bitrate than 152k. Even when it says it does so the resulting files still have 152k instead of 192k. ffmpeg also has/had a bug not writing the bitrate into the audio file tags which means when testing you have to calculate the bitrate manually by dividing the filesize by the length of the audio in seconds (resulting in 152k - see above) choosing faac as converter gets me the same results other programs don't work reliably (see this thread Howto convert audio files to *.m4a? I know that this is not an original new problem but I am wondering if there is still no way to convert with ubuntu/kubuntu 12.04 after a lot time passed and I can't find some of the bug issues mentioned in the other thread anymore. So: Is there a solution after all?

• Game has noticeable frame drops but when through a profiler it always runs smooth

  - by felipedrl

  I'm trying to optimize my PC game but I can find the bottleneck since every time I run it through a profiler (gDEBugger) it runs smooths. When running outside gDEBugger I get these annoying hiccups. It's not just the graphics, the sound also gets choppy. The drops are inconsistent across runs, i.e, sometimes I run the same scenario and get no drops at all, sometimes I get a few drops, and others the game is consistently slow. The only constant is: when running through gDEBugger I ALWAYS get a smooth run. I'm suspecting something outside my game is interfering and causing these drops, but what in the hell does gDEBugger do that nullifies these drops? A higher process priority? Any ideas? Thanks in advance.
