• Webcast: Maximum Availability with Oracle GoldenGate

  - by Markus Weber

  Make sure to register here for this upcoming live webcast, with great speakers, and a live Q&A chat session.It is scheduled for Thursday, December 13th, 2012, at 10am Pacific Time. There are no doubts about the strength, and depth, of Oracle's offerings for highly available database environments. But depending on the nature of your data center environments, your different uses cases and workloads, your service level agreements and expectations, there might still be some open questions about what the best solutions and architectures are to assure high availability and/or affordable, efficient disaster recovery. Therefore, this webcast will answer questions such as: How does Oracle GoldenGate fit into Oracle's Maximum Availability Architecture ? When to use Oracle Active Data Guard ? When Oracle GoldenGate ? When both ? When Oracle GoldenGate is a definite requirement for Database High Availability ? Overall, what are new high availability features in Oracle GoldenGate 11g Release 2 ?

• Is there a simple shopping cart I can add to my existing website?

  - by Kalessin

  I created a website for my wife, who knits scarves. The site simply displays the 18 different colours she has created, with a Lightbox-like large photo available when clicked. She would now like to give visitors the option to purchase online and pay with PayPal and possibly Google Checkout. We do not need a full ecommerce solution; I've looked at several and they all seem to be overkill for our requirements. We don't even need categories. "All" I want is something that will add products to a cart, take the customer details and integrate the payment provider. So far, the best solution I have found seems to be this script on Codecanyon and I wanted to find out if anyone knows of any better products before I commit to this route. Thanks for your help!

• What language(s) do I need to learn in order to develop an application like this?

  - by Josh

  I have an idea for making a web application. Ideally this application would have products which prices are increased each time a Retweet of the product at hand is made. Kind of like bids with tweets. Unfortunately my web development knowledge is very scarce. I know just basic HTML, virtually no CSS and that's it. I'm kindly asking for your insights on what you think would be best for making a web app like this. I have no good idea of where to start or what I need to get going. Your inputs are greatly appreciated. Thanks in advance.

• Component based design, but components rely on eatchother

  - by MintyAnt

  I've begun stabbing at a "Component Based" game system. Basically, each entity holds a list of components to update (and render) I inherit the "Component" class and break each game system into it. Examples: RenderComponent - Draws the entity MovementComponent - Moves the entity, deals with velocity and speed checks DamageComponent - Deals with how/if the entity gets damaged... So. My system has this: MovementComponent InputComponent Now maybe my design is off, but the InputComponent should say things like if (w key is down) add y speed to movement if (x key is down) Trigger primary attack This means that the InputComponent sort of relies on these other components. I have to do something alone the lines of: if (w key is down) { MovementComponent* entityMovement = mEntity->GetMovement(); if (entityMovement != NULL) add y speed to movement } which seems kinda crappy every update. Other options? Better design? Is this the best way? Thanks!

• Assigning a different texture based on picking(XNA)

  - by Thomas Carmichael

  I'm making a game using XNA. I have some simple objects like cube and sphere, and I would like to change the texture of one face of these objects based on picking. That is, when the cursor is over one face, it turns red. The only way I've seen to do this is to overload the content processor as here: http://xbox.create.msdn.com/en-US/education/catalog/sample/picking_triangle but it seems like it shouldn't be this complicated. I'm using .x models, and would like to be able to implement this for more complex models in the future beyond cubes/spheres/etc. Is this the best/only way to go about it? I'll figure that out if that's what is necessary, but it seems that there would be a simpler solution to load a different texture to a face than I've seen, I just don't know what it is.

• Computer Science Career Advice: Master's in Computer Science vs. Software Engineering?

  - by Everton

  Hello, I am a college student and I am majoring in Computer Science and Applied Mathematics. As I get closer to my senior year I have noticed that continuing my studies is the best choice right for me now. I see that several universities offer an Computer Science Master's Degree and an Software Engineering degree. What are their pros and cons? I feel that while the Computer Science master's degree seems a little too broad the Software Engineering is too restrictive. I did not decide yet between an career of Software development or research ( algorithm development among other things ). Any advice would be greatly apreciated!

• Bandwidth heavy site... use co-location?

  - by darron

  I'm working on a web site that is likely to be very bandwidth-heavy. A major feature of the site when in active use can pull up to 1Mbps for a single session. Luckily, once users get over the new toy factor, the use of this feature will probably be 1-5% or less (probably much less) of session time. However, new users are likely to play with this feature a good bit, especially at launch. I'm very concerned about bandwidth use. This is more or less a niche market, so I won't ever be needing to scale to crazy levels like YouTube. However, it is entirely possible for it to be a couple terabytes/month. Is co-location my best option? What cheap bandwidth services (colocation/hosted/cloud/whatever) are out there?

• HTML5 Game (Canvas) - UI Techniques?

  - by Jason L.

  Hi! I'm in the process of building a JavaScript / HTML5 game (using Canvas) for mobile (Android / iPhone/ WebOS) with PhoneGap. I'm currently trying to design out how the UI and playing board should be built and how they should interact but I'm not sure what the best solution is. Here's what I can think of - Build the UI right into the canvas using things like drawImage and fillText Build parts of the UI outside of the canvas using regular DOM objects and then float a div over the canvas when UI elements need to overlap the playing board canvas. Are there any other possible techniques I can use for building the game UI that I haven't thought of? Also, which of these would be considered the "standard" way (I know HTML5 games are not very popular so there probably isn't a "standard" way yet)? And finally, which way would YOU recommend / use? Many thanks in advance!

• Hurricane Season 2010 Starts

  - by Mark Treadwell

  Here we are at the start of another hurricane season.  As with past years, I have been preparing.  Last year I had the house painted with a high-quality paint, giving the stucco its best waterproofing possible.  I have a few cracks to patch with elastomeric patching material.  I will paint it to match the house later.  I also need to clean out the anchors for the lower angle brackets and reattach them.  I had removed the brackets for painting. You can read all my past hurricane entries here.  The predictors are promising a busy season.  We have heard that one before, so I put little credence in long range press releases.  Other than that we are pretty much ready.  I have a few new plans I will blog about later, but for now we get to listen to our daily thunderstorms outside.

• What is the biggest weakness of students graduating with degrees in Computer Science?

  - by akobre01

  This question is directed more toward employers and graduate student advisors/professors but all opinions are welcome. What do you find is a common weakness of new hires and/or new grad students? Is it entirely variable dependent on the student and his or her university? Is there a particular skill or skillset that you wish new hires/researchers had expertise in and how can we remedey this deficiency? I realize that this question is general and really encapsulates two questions, one more about the weaknesses of new software engineers and one about the weaknesses of new researchers. However, both types of people tend to come from similar courses of study so I'm wondering if there is any overlap. Note: I am not a professor but I'm interested in how best to revise the undergraduate curriculum in CS.

• Do you think that in the future it'll be possible to develop games on OS X by using Python and the latest library "Sprite kit" made by Apple? [on hold]

  - by Cesco

  I don't understand a lot about game engines and modules for Python, even though I'm aware of the existance of PyGame and Pyglets, so please don't bash me too hard if I'll wrote something wrong in this question :-) When I upgraded my Mac to the latest version of OS X, I noticed for the first time that Apple is providing a library named Sprite kit for developing games on both iOS and OS X. It looks to me fairly complete, and the fact is managed by a big company gives me the impression of being well-supported for the time being; in summary, it looks... cool. Actually in order to take advantage of "Sprite kit" you need to code in Obj-C. Since I don't know Obj-C but only a little bit of Python, do you think that there's a chance that sooner or later someone will make a wrapper for Python ? Thank you very much and best regards

• Dead (nearly blank) laptop screen, secondary screen works - how to fix?

  - by LIttle Ancient Forest Kami

  My laptop screen is black while my secondary screen is fine. What I tried: setting brightness (Fn keys) - no effect, no change seen, also on secondary screen removing static electricity like suggested here - no effect restarting / charging battery, running on battery / "wall" power - no effect as well wait to see if warming it up helps - it doesn't follow official Ubuntu diagnostics - checking now... What I will try next: check last updates I've made IIRC I am running on nomodeset already, but can't recall how to verify this Further symptoms: can't see BIOS screen system loads and works fine, just screen has problems screen works (occasionally I could glimpse very dimly what was going on, but it was like with minimum brightness set - nearly non-distinguishable from just a black screen) Any ideas how to proceed best? What is most probable cause?

• Most efficient way to generate 2D portraits

  - by user1221

  Hey, I am not sure if this is a fitting question for gamedev, or if it is too art related. I am currently trying, to create 2D character protraits for my game. At first I tried to draw them and even though it helped polishing my drawing skills the end result either required way too much time or it simply looked like it was created by a grade school kid. So I am currently looking into some tools which from which people like me who are not out of the art-world might benefit. Especially tools which can create a 3D head+hair, so that I can render them. I have tried several 3D generation tools such as makehead and makehuman to create the basic head-shape. But I have to admit I am not well versed in what other options are available/what has the best quality/etc.

• How do I draw a texture to a MSTerrain object?

  - by Brad

  I'm using Farseer to make a game in XNA and I can't seem to figure this out. I've decided to use MSTerrain for making my game's terrain because I wanted destructible terrain and MSTerrain seemed like the best bet. Unfortunately, I'm stumped on how to actually show the terrain. When I generate the terrain it's visible in debug view, but MSTerrain does not have a Draw method, so I'm wondering how it is supposed to be drawn to the screen? Is it worth pursuing? I'm starting to think that MSTerrain is more trouble than it's worth, is there another better way to do this with bodies?

• Fast lookup for organization hierarchy

  - by Élodie Petit

  I need a way to implement a fast lookup algorithm / system to find users very quickly in a multi-level department and multi-level employee/manager relation organization structure. Departments can have any level of departments and users directly connected to departments. User are connected to departments and other users at the same time. What would be the best approach to implement such a system? There will be approximately 2000 users and 30 departments. Is there a good way to hold all of this information on memory?

• Dell Vostro 1510 trackpad

  - by user18055

  A week ago I moved totally from Windows 7 to Ubuntu. I've been really happy with the transition bar one annoying glitch. My trackpad sometimes works, sometimes doesn't. All other hardware including peripherals work flawlessly, including a Logitech ball mouse, Wacom Bamboo pen and touch and wireless Logitech keyboard and mouse combo. I can't see any pattern to when and why the trackpad works. Occasionally on rebooting, it will work, but then I can reboot 10x in a row and it won't work, then I leave it a day, then reboot and it works flawlessly. Any ideas on a solution or appropriate method for me to deb it? My knowledge of Ubuntu/Linux is sketchy at best so I could do with a little help :)

• Alerts are good, aren't they?

  - by fatherjack

  It is accepted best practise to set some alerts on every SQL instance you install. They aren't particularly well publicised but I have never seen any one not recommend setting up alerts for Error 823, 824 and 825. These alerts are focussed on successful access(IO) to the hard drives that SQL Server is using. If there are  any errors when reading or writing to the drives then one of these errors will be returned. Having the alerts on these errors means that any IO issues will be brought to the...(read more)

• schema.org specification for generic pages or posts on a CMS

  - by NateWr

  I'm trying to determine the best possible schema.org type to declare for the content section in the template of a content management system, which will handle regular news posts for small, local hospitality businesses. The type should represent the content of that page, which is likely to be a wide range of things. The description for Article pretty strongly encourages its use to be limited to the articles of a publication. For purely semantic reasons, I'm not sure if Blog is appropriate in this case -- businesses won't be creating typical "blog" content but are more likely to be writing about upcoming events, special deals, awards, etc. Would Webpage be appropriate in this instance? Although I'm a fan of the schema.org concept, I frequently find myself unsure how broadly or narrowly I'm meant to infer the meaning of a type. In such cases, is it safe to use a high-level element, such as CreativeWork, or does this blunt the usefulness of the markup?

• Is it good to use same keyword for multiple pages in one domain?

  - by Phanen

  Hi, I want to know after Google recent updates, will it be good opt to use same keywords for multiple pages? Say- my keyword is "driver update" and I have a folder "HP" in website. Hp has lots of models like HP Elitebook, HP Envy, HP Mini, HP Pavilion and much more. HP Elitebook has many versions like HP Elitebook 2530p, HP Elitebook 2730p, HP Elitebook 8530w. Now should I create pages like "Driver update in HP Elitebook 2530p" , "Driver update in HP Elitebook 2730p", "Driver update in P Elitebook 8530w" or a single page "Driver update in HP Elitebook"? Which one will be the best option for better SE ranking- " single page or multiple pages using same keyword for different model versions" ?

• How to conduct A/B split testing with AdSense?

  - by None

  Ok so I have decided to A/B test my AdSense ads. I have run a few tests, but I don't know what conclusion to draw and how to keep track of things. Some specific questions: If I have 2 test units, 1 wins. I test that with a new and so on. How do I find if say the fifth one did better than the first one? How do I keep track of things? Do I let the variables independent of each other, because they certainly are not. In real life, font size can affect CTR even if the colors are different. I can test blue color with red color, and then test Arial font with Georgia, but how do I know which combination is the best? This would result in way too many test units. I tried Googling a lot, but I could not find answers to these questions.
