• EXADATA & GoldenGate - the perfect combination for thetrainline.com

  - by maria costanzo

  enhanced the customer experience sustaining rapid search and booking times for hundreds of millions of journey requests per annum EXADATA & GoldenGate : the perfect combination thetrainline.com used Oracle GoldenGate to migrate data from its legacy system to two  Oracle Exadata Database Machine X2-2 HC Quarter Rack instances to reduce downtime, avoid  risk of data loss, and eliminate the need for complex programming. "Oracle GoldenGate enabled us to complete the migration of three terabytes to Oracle Exadata, within a single 30-minute system outage,” East said. "Without Oracle GoldenGate, we would have required a 20 hour outage window to complete the migration, something that was completely unacceptable."  Discover more at the following link

• Dealing with engineers that frequently leave their jobs [closed]

  - by ??? Shengyuan Lu

  My friend is a project manager for a software company. The most frustrating thing for him is that his engineers frequently leave their jobs. The company works hard to recruit new engineers, transfer projects, and keep a stable quality product. When people leave, it drives my friend crazy. These engineers are quite young and ambitious, and they want higher salaries and better positions. The big boss only thinks about it in financial terms, and his theory is that “three newbies are always better than one veteran” (which, as an experienced engineer, I know is wrong). My friend hates that theory. Any advice for him?

• Determine how to display a tile based on surrounding tiles

  - by Jsmith

  I have a game engine which generates maps randomly, set on a 2d grid which is composed of 34px square graphical tiles. These tiles can be displayed in any of three ways, wall, corner, and floor(exists in 2 states, passable and impassible), and four directions, north, south, west and east. What I need to do is, based on the tiles around each individual tile, determine which state to display the tile in, e.g. north wall, northeast corner, floor so that when a player alters the map, the tiles around the affected tile adjust themselves to suit(i.e. tunneling). In case it becomes important, all gameobjects are inherited from the same class, whether they be players, NPC's, walls, or items.

• What is the right approach to use adsense with responsive web design?

  - by Sisir

  Recently I was studying responsive design a lot and designed couple of sites. But i was wondering how would I use google adsense (which is pixel based) ads on my responsive design? Very typical example is suppose I have a 728x90 ads on header. Or if i do a mobile first approach i would need different versions of ad sizes for different view posts but google doesn't allow more than three ad unit per page (as far as i know). So, Question: What is the right approach/best practice of using google adsense on a responsive site design?

• Backup and the evil RETAINDAYS option

  - by TiborKaraszi

  "So what bad has this option done?", you probably as yourself. Well, not much, but I find it evil because it confuses people, especially those new to SQL Server. I have many times seen people specifying something like 3, and expect SQL Server to keep the three most recent backups in the backup file and overwrite everything which is older than that. Well, that is not what the option does. But before we go into details, let's look at an example backup command which is using this option: BACKUP DATABASE...(read more)

• Can WebGL be used to create a tile-based multi-layer scrolling platform game?

  - by Nicholas Hill

  I've found WebGL (based on OpenGL) to be a fiendish and unforgiving framework for those learning to write HTML5-based games. Despite the presence of many examples on how to get started, I'm really struggling to understand how I could simply load a bunch of images and render them to a canvas quickly using WebGL. My specific scenario involves trying to render a map using a bespoke but simple multi-layered tile engine, where each value in a three dimensional array points to the image to use for that location in the rendered image. Think "Sonic the Hedgehog" via tilesets, tiles, maps, layers, sprites etc. Can anyone enlighten me: 1) How can I load an image that I can use as a texture in WebGL? 2) How can I dynamically select an image at run time and draw it at any co-ordinate, that I also select at run time?

• Rapid Application Development, good, bad or ugly?

  - by chrisw

  I have been working for such a shop for the past three years and I know deep down it cannot be like this everywhere. When I think of Rapid Application Development I immediately think programming without fore-thought. For example, when my company decides to come out with a new product, they don't do any type of relationship mapping, no ER diagrams, no round table discussions on expandability. No, the senior developer that ends up working on the product puts together a screen shot walk-through of the application to show to the client. Once the client signs off on the project work is underway by the senior developer. Now you have a senior developer (I use that term "senior" loosely) coding the application in under a week with no unit testing. Well I guess the good to this is it keeps programmers employed due to the enormous amount of unforeseen "features" in the newly created application. Have any of you dealt with a company like this? If you did how did you preserve your sanity?

• Long term planning and agile?

  - by Ignite

  My team has recently went through the process of laying out a nearly one year plan for our direction of work. We have separated the plan into three phases and each phase will include a couple of launches. I wonder, from an agile point of you, is what we do wrong? I think it's not a bad idea, because we haven't spent too much time on designing anything but the first few steps and it's possible for us to change direction. At the same time it's nice that we don't act with only the near term in sight.

• What happens between sprints?

  - by Steve Bennett

  I'm working on a project loosely following the scrum model. We're doing two week sprints. Something I'm not clear on (and don't have a book to consult) is exactly what is supposed to happen between sprints: there should be some "wrap" process, where the product gets built and delivered, but: how long does this typically take? should the whole team be involved? does it strictly have to finish before developers start working on the next sprint items? is this when code review and testing take place? There are three developers, adding up to about 1 FTE. So the sprints are indeed very short.

• How to render Minecraft on the GPU?

  - by l0b0

  Hardware: Intel i7 AMD Radeon HD 6970 SSD with plenty of space 6 GB RAM Software OpenJDK 6, 7, and Oracle Java 7 (reproducible with all three) AMD Catalyst 12.8 and open source driver (reproducible with both) Ubuntu 12.04 x86_64 and older Minecraft 1.3.2 vanilla and older On this setup I am getting rubbish frame rates after a short while of playing, dropping from about 45-55 to 15 in a couple of minutes. CPU use is 40-45 even when rendering the opening screen at 1920x1280, and gameRenderer is using about 90% CPU when playing. Rather than trying to eke out a few more FPS out of an obviously broken rendering pipeline, I really hope to find a solution to make the GPU render Minecraft.

• What does private cloud Daas or DBaaS really mean ?

  - by llaszews

  Just had meeting with Fortune 1000 company regarding their private DBaaS or DaaS offering. Interesting to see what DBaaS really means to them: 1. Automated Database provisioning - Being able to 'one button' provision databases and database objects. This includings creating the database instance, creating database objects, network configuration and security provisioning. It is estimated that just being able to provision a new DB table in automated fashion will reduce time required to create a new DB table from 60 hours down to 8 hours. 2. Virtualization and blades - DBaaS infrastructure is all based upon VMs and blades. 3. Consolidation of database vendors - Moving from over ten database vendors down to three.

• The Challenges of Corporate Financial Reporting

  - by Di Seghposs

  Many finance professionals face serious challenges in managing and reporting their company’s financial data, despite recent investments in financial reporting systems. Oracle and Accenture launched this research report to help finance professionals better understand the state of corporate financial reporting today, and why recent investments may have fallen short. The study reveals a key central issue: Organizations have been taking a piecemeal—rather than holistic—approach to investing. Without a vision and strategy that addresses process improvement, data integrity, and user adoption software, investments alone will not meet the needs or expectations of most organizations. The research found that the majority of finance teams in 12 countries—including the U.K., USA, France, Germany, Russia, and Spain—have made substantial investments in corporate financial management processes and systems over the last three years. However, many of these solutions, which were expected to improve close, reporting, and filing processes, are ineffective, resulting in a lack of visibility, quality, and confidence in financial data. Download the full report.

• How should I synchronize configurations and data across computers?

  - by lfaraone

  Imagine I have three Ubuntu computers home, laptop, beach-house. They all have the same version of Ubuntu, 10.04 installed, and are kept up to date from the repositories. I use f-spot, thunderbird, and google-chrome on all of the computers. Is there a way to keep the data and configuration in sync across them, without requiring constant connectivity for normal (non-synchronous) usage? For example, they should be usable without network connectivity, so something like NFS won't work. An ideal solution would not require manual action to start the syncing process.

• Going from webforms, VS 2008, 3.5 framework to the "next level" based on my goals

  - by Caveatrob

  I've got a few choices to make as I develop some business websites that will run for the next two to three years. Currently I run ASP.NET 3.5 with Visual Studio 2008. I do my development rather crudely in WebForms because that's what I learned and am most productive with. I don't use Membership or any other frameworks in my projects. I use a simple class that maintains a few session keys for each user based on basic database tables for users and roles. (I have about 3,000 users). So far I've kept the data simple, using ADO.NET against SQL Server and a data access class (Circa 2000, I know) to build my sites. My questions are as follows: Under what conditions would I be better off moving to MVC? Under what conditions would I find LINQ and ORM a better way to go than standard ADO.NET? Would I benefit, in my current state of development, from going from Studio 2008 to Studio 2010?

• Will adsense 'use' comments between the adsense opening and closing tags for ad targeting?

  - by SuperSpy

  I've got a simple website on which students of my school can see their timetable. I setup adsense three weeks ago and everything is working fine. But I would like to help adsense. Since only a timetable and a few instructions are shown, there is scarcely content to which ads can relate. Idea: <!- google_ad_section_start –> <!-- Students like clothing ... and bargains, etc.--> <!– google_ad_section_end –> Will this work? Or are there other ways to help adsense?

• How to divide hex grid evenly among n players?

  - by manabreak

  I'm making a simple hex-based game, and I want the map to be divided evenly among the players. The map is created randomly, and I want the players to have about equal amount of cells, with relatively small areas. For example, if there's four players and 80 cells in the map, each of the players would have about 20 cells (it doesn't have to be spot-on accurate). Also, each player should have no more than four adjacent cells. That is to say, when the map is generated, the biggest "chunks" cannot be more than four cells each. I know this is not always possible for two or three players (as this resembles the "coloring the map" problem), and I'm OK with doing other solutions for those (like creating maps that solve the problem instead). But, for four to eight players, how could I approach this problem? As always, any and all help is appreciated. :)

• Logitech K260 keyboard responds very, very slow

  - by Pierre

  I bought a Logitech K260 wireless keyboard/mouse combination and connected it to my Ubuntu 12.04 workstation. The mouse seems to work fine for now, it is quick and is working quite smoothly. The keyboard however is very, very slow. It takes about two to three seconds for a character to appear after being typed. What might be the problem? I have found even a review of someone who states that he's gaming with this keyboard, which I am not planning to do, for me it will serve as a writing keyboard only as soon as it works properly. Who might be able to help?

• How can I add missing Fn-key controls?

  - by Alex Ball

  I have a Toshiba NB200 netbook. The majority of the Fn-key controls come through fine and are recognized by my OS (I'm running Kubuntu 12.04/KDE 4.9) but according to the markings on my keyboard there are a few more that xev isn't detecting, i.e. Fn + F9 (touchpad toggle) Fn + 1 (increase screen resolution) Fn + 2 (decrease screen resolution) Fn + Space (zoom) Now, I don't particularly need those last three but I thought it would be quite useful to remap them to, say, Media Previous, Media Next, and Media Play, but I can't do that if the signals aren't getting through. Is there any way for me to persuade the OS to recognize these keystrokes? I've tried using acpi_listen to detect scancodes but it doesn't pick up any of function-related Fn-key strokes (like Audio Mute, which does work by the way).

• Dynamic website SEO development

  - by Pankaj Upadhyay

  I made a website which stayed online for 6 months. During that period the search results for the site were not at all good. Even typing the domain name yielded just two or three category result. Now, I have taken the site down for total redevelopment and redesign. The aim of this question is to know the basics for SEO to be done while redesigning the site. My site will be in ASP.NET MVC 3 and will have main categories, sub categories and sub-sub if any. Then there will be products in those categories. All the data will come from MSSQL DB. Please tell me just the basics required for a dynamic website during development. I want to ensure that google and other engines index all the pages of my site including products or whatever.

• Google search does not show sub-pages from my website

  - by user5679

  My website appears in Google search, but only the first page. Of course I have sub-pages linked from the first page, but the sub-pages do not show in Google search. Not in Yahoo, not in Bing. What should I do? It has been three years that sub-pages do not show. (I tried searching site:mydomain.com and pressed 'repeat the search with the omitted results included' link) What would you suspect the reason? My website addresses were like xxx.php?yy=zzz etc, etc, so I changed it to /yy/zzz using mod_rewrite. I thought it might be (X)HTML standard violations, so now I changed it. I hope Google will soon have my entire website, but I am a little bit pessimistic. Do you have any thought?

• How do I optimize SEO in a multiblog WordPress install?

  - by user35585

  We are about to launch two product pages plus a corporate website. The goal is to keep a blog in all of the sites, but here it comes the question about how to do it in a way we get everything unified but do not mess with Google's web crawlers. We considered the following options: Putting a blog from which we retrieve two categories with custom CSS, so we have a blog that sub splits two category-dependent blogs; this way we can get the feeds and will point to it Putting two product blogs of which we retrieve their posts into a bigger, corporate blog Putting three independent blogs Despite I was for the first option, so we only have to address our content from the product pages, I would sincerely like to hear your opinion. We are afraid duplicate content or strange link games may make us lose PageRank. How would you do it?

• Xubuntu LightDM shows blank screen half the time

  - by Sman789

  System info: (will be amended if any more info is asked for) My laptop runs Xubuntu 12.10. As it has a Solid State Drive, /tmp, /var/tmp, /var/log and /var/log/apt are set to tmpfs in the /etc/fstab file - in case this makes any difference. Problem My problem is quite simple. Approximately 50% of boot attempts end in the mouse cursor on a black screen (presumably LightDM failing to load), forcing me to restart and try again. I can access the CTRL+ALT+F1 terminal to reboot the machine, but it's very annoying having to boot and reboot two or three times before one works. Oh, and this problem is the same whether I use the Xubuntu or Unity greeter. Thanks for any help you can give.
