  • Automation at GUI or API Level in Scrum

    - by Sani Parwani
    I am a Automation Engineer. I use QTP for Automation. I wanted to know couple of things. In a scrum Project which has 2 weeks of work, how can complete automation be done in that time frame (talking only about the GUI Level)? Similarly, how can API Level of automated testing be accomplished, especially inside a single sprint? And what exactly is API level testing? How to begin with API Testing? I assume QTP is not the tool here certainly.

  • How to create a large level game?

    - by Siddharth
    I want to know how to create a large game which has more than one level in it and those levels are loaded from the xml file. In my game I have many objects for each different level which I have to load when use click on it. At present for example my game contain 20 levels and now I was loading all the graphic object for all 20 levels. But the correct way was that only load graphic of that particular level only. So I don't know how to do that. So please explain this by providing game example. At present I was creating a class for each my game object image by extending sprite to it. I know it was not a suitable way so provide guidance on it. Basically I want to know how to create large games in andengine? Please help me about that because it will provide help to other community member also because andengine did not have proper documentation for learning developer about how to manage large game?

  • implementing a high level function in a script to call a low level function in the game engine

    - by eat_a_lemon
    In my 2d game engine I have a function that does pathfinding, find_shortest_path. It executes for each time step in the game loop and calculates the next coordinate pair in the series of coordinates to reach the destination object. Now I want to call this function in a scripting language and have it only return the last coordinate pair result. I want the game engine to go about the business of rendering the incremental steps but I don't want the high level script to care about the rendering. The high level script is only for ai game logic. Now I know how to bind a method from C to python but how can I signal and coordinate the wait time between the incremental steps without the high level function returning until its time for the last step?

  • Low framerate on background apps

    - by user1698923
    My problem is that when a game is running in the foreground, in Full Screen mode, any applications on my second monitor (such as youtube videos, videos, not app specific) drop their frame-rate to about 2-3 FPS. It seems like some sort of power management option that I can't track down. As far as I can tell, it's not due to the GPU not being able to keep up. For instance, my PC can play League of Legends at about 280FPS when the framerate is uncapped. If i cap it at 60FPS using the in-game option, it has no affect on the performance of the background app. Summary Operating System Windows 8 Pro 64-bit CPU Intel Core i7 3820 @ 3.60GHz 42 °C Sandy Bridge-E 32nm Technology RAM 12.0GB Triple-Channel DDR3 @ 533MHz (7-7-7-20) Motherboard Gigabyte Technology Co., Ltd.

  • Implementing Service Level Agreements in Enterprise Manager 12c for Oracle Packaged Applications

    - by Anand Akela
    Contributed by Eunjoo Lee, Product Manager, Oracle Enterprise Manager. Service Level Management, or SLM, is a key tool in the proactive management of any Oracle Packaged Application (e.g., E-Business Suite, Siebel, PeopleSoft, JD Edwards E1, Fusion Apps, etc.). The benefits of SLM are that administrators can utilize representative Application transactions, which are constantly and automatically running behind the scenes, to verify that all of the key application and technology components of an Application are available and performing to expectations. A single transaction can verify the availability and performance of the underlying Application Tech Stack in a much more efficient manner than by monitoring the same underlying targets individually. In this article, we’ll be demonstrating SLM using Siebel Applications, but the same tools and processes apply to any of the Package Applications mentioned above. In this demonstration, we will log into the Siebel Application, navigate to the Contacts View, update a contact phone record, and then log-out. This transaction exposes availability and performance metrics of multiple Siebel Servers, multiple Components and Component Groups, and the Siebel Database - in a single unified manner. We can then monitor and manage these transactions like any other target in EM 12c, including placing pro-active alerts on them if the transaction is either unavailable or is not performing to required levels. The first step in the SLM process is recording the Siebel transaction. The following screenwatch demonstrates how to record Siebel transaction using an EM tool called “OpenScript”. A completed recording is called a “Synthetic Transaction”. The second step in the SLM process is uploading the Synthetic Transaction into EM 12c, and creating Generic Service Tests. We can create a Generic Service Test to execute our synthetic transactions at regular intervals to evaluate the performance of various business flows. As these transactions are running periodically, it is possible to monitor the performance of the Siebel Application by evaluating the performance of the synthetic transactions. The process of creating a Generic Service Test is detailed in the next screenwatch. EM 12c provides a guided workflow for all of the key creation steps, including configuring the Service Test, uploading of the Synthetic Test, determining the frequency of the Service Test, establishing beacons, and selecting performance and usage metrics, just to name a few. The third and final step in the SLM process is the creation of Service Level Agreements (SLA). Service Level Agreements allow Administrators to utilize the previously created Service Tests to specify expected service levels for Application availability, performance, and usage. SLAs can be created for different time periods and for different Service Tests. This last screenwatch demonstrates the process of creating an SLA, as well as highlights the Dashboards and Reports that Administrators can use to monitor Service Test results. Hopefully, this article provides you with a good start point for creating Service Level Agreements for your E-Business Suite, Siebel, PeopleSoft, JD Edwards E1, or Fusion Applications. Enterprise Manager Cloud Control 12c, with the Application Management Suites, represents a quick and easy way to implement Service Level Management capabilities at customer sites.

  • Low level Linux graphics

    - by math4tots
    For educational purposes, I'd like to write an application on a Linux environment that can process keyboard events and draw graphics without huge dependencies like X or SDL. I presume that this must be possible, because X and SDL are just programs themselves, so they must rely on other methods inherent to the environment. Is this understanding correct? If so, where might I learn to write such a program? My limited experience tells me that it would involve making calls to the kernel, and/or writing to special files; however, I haven't been able to find any tutorials on the matter (I am not even sure what to Google). Also, in case it is relevant, I am running Debian Squeeze on Virtualbox. I have used a netinst cd without networking, so there isn't much installed on it currently. I will install gcc, but I am hoping I can get by with nothing more.

  • Ubuntu stuck in low resolution after UNinstalling / disabling NVidia drivers

    - by Han Cnx
    Tried the Nvidia driver, installed using the Additional Drivers panel. Didn't like it much; the CPU seemed to overheat more and the brightness controls stopped working. Also selecting a second display is a pain using that horrible NVidia settings thing. So wanted to disabled it again.. problem is, UBuntu is then stuck in either 640x480 or 800x600 (second time I tried to install it back and then remove again). How can I get this back the way it was? The original Ubuntu drivers worked just fine, allowing me to run Unity and games properly. I tried a xserver-xorg reconfigure but this didn't do anything. (No xorg.conf file either). This is on a Lenovo Thinkpad T410i

  • Flash: Memory usage is low but framerate keeps dropping

    - by Cyborg771
    So I'm working on a puzzle game in flash. For all intents and purposes it's like Tetris. I spawn blocks, they move around the screen, then they get destroyed and disappear. I was having some trouble with the memory usage being too high over time so I read up on memory management and I think I have that figured out now. It's definitely climbing slower than it was before, but the framerate is still taking a huge dive after playing for a while. If it's not a memory leak what else could be causing this? Thanks in advance.

  • Hosting multiple low traffic websites on ec2

    - by Niko Sams
    We have like 30 websites with almost no traffic (<~10 visits / day) which are currently hosted on a dedicated server. We are evaluating hosting on Amazon EC2 however I'm not sure how to do that properly. One (micro) instance per website is too expensive ~10 websites on one instance (using apache virtual hosts) make auto scaling impossible (or at least difficult) Or is cloud computing not suitable for such a usecase?

  • Ubuntu LiveCD/USB image that boots directly to low graphics desktop

    - by user14146
    I use Ubuntu as a diagnostic tool sometimes, and it would be great to get a modification that lets you boot directly to the LiveCD desktop, preferably with the special effects dialed down. Is there such a tool? Unetbootin doesn't seem to let you do this, and Remastersys could probably do this, but I'd have to dig into the code quite a bit and figure out what to remove, which I can do, but I figured someone might have already done this and would save me the trouble.

  • Styles of games that work at low-resolution

    - by Brendan Long
    I'm taking a class on compilers, and the goal is to write a compiler for Meggy Jr devices (Arduino). The goal is just to make a simple compilers with loops and variables and stuff. Obviously, that's lame, so the "real goal" is to make an impressive game on the device. The problem is that it only has 64 pixels to work with (technically 72, but the top 8 are single-color and not part of the main display, so they're really only useful for displaying things like money). My problem is thinking of something to do on a device that small. It doesn't really matter if it's original, but it can't be something that's already available. My first idea was "snake", but that comes with the SDK. Same with a side-scrolling shooter. Remaining ideas include a tower defense game (hard to write, hard to control), an RPG (same), tetris (lame).. The problem is that all of the games I like require a high-resolution screen because they have a lot of text. Even a really simple game like nethack would be hard because each creature would be a single color. tl;dr What styles of games require a. No text; and b. Few enough objects that representing them each with a single color is acceptable? EDIT: To clarify, the display is 8x8 for a total of 64 pixels, not 64x64.

  • Read Committed isolation level, indexed views and locking behavior

    - by Michael Zilberstein
    From BOL, " Key-Range Locking " article: Key-range locks protect a range of rows implicitly included in a record set being read by a Transact-SQL statement while using the serializable transaction isolation level . The serializable isolation level requires that any query executed during a transaction must obtain the same set of rows every time it is executed during the transaction. A key range lock protects this requirement by preventing other transactions from inserting new rows whose...(read more)

  • Installed Ubuntu In a low Specs PC and it is too slow, even with LXDE

    - by Herudae
    I'm new with Linux and started with Ubuntu 11.10, I installed it in my PC (Core2Duo 2Ghz, 512Mb Ram DDR2, integrated video in Motherboard), I know the requirements for Unity are 1Gb Ram so I decided to download a Desktop environment more lightweight, so I Installed LXDE, it loads very fast, compared to the 3.5 min from login screen to open desktop in Unity, but it freezes every time I open a single program, I can't even navigate in Internet, it freezes, sometimes for a pair of minutes and the graph at bottom right is all green as if iyt were using 100% CPU, it happens with every program. As additional data it takes 3+ min to get from boot system selection screen to Login screen and 3.5 Min more to get into Ubuntu with Unity, with LXDE it turns to 30 secs aproximately. Is Ubuntu + LXDE Desktop Environment Package = Lubuntu? or should I download Lubuntu directly instead? I installed some other desktop environments, as Gnome but it doesn't log in, the screen just turns grey. Should I get an older Ubuntu version? I'm thinking about uninstalling Ubuntu but I'll try to deplete the options, thanks for your support.

  • Low resolution Dektop intel i7 3770 and intel board DH67BL

    - by rtorres
    I installed Ubuntu 12.04.1 in a desktop with the following specs: CPU: Intel(R) Core(TM) i7-3770 CPU @ 3.40GHz Motherboard: Intel DH67B However the monitor is not identified (Monitor: Unknown) such that maximum resolution is 1024x768. This occurs with Samsung Syncmaster 2033 (resolution 1900x600), and is the same with ViewSonic VX2453mh-LED (resolution 1920x1080). I'd be very grateful if anyone could give me a suggestion as to how to fix the resolution.

  • Circular motion on low powered hardware

    - by Akroy
    I was thinking about platforms and enemies moving in circles in old 2D games, and I was wondering how that was done. I understand parametric equations, and it's trivial to use sin and cos to do it, but could an NES or SNES make real time trig calls? I admit heavy ignorance, but I thought those were expensive operations. Is there some clever way to calculate that motion more cheaply? I've been working on deriving an algorithm from trig sum identities that would only use precalculated trig, but that seems convoluted.

  • What are the reasons for MMOs to have level caps [on hold]

    - by SamStephens
    In many MMOs players character progression is artificially capped, e.g. by level 60 or 90 or 100 or whatever. Why do MMOs have these level caps in the first place? Why not just allow characters to continue to arbitrary levels with a mathematically designed leveling system that keeps the leveling experience interesting and endless? Answers to this question may help us to see the reason behind the feature and decide if and how this should be implemented in our MMOs.

  • Screen resolution is too low with open source drivers on Ubuntu 12.10

    - by Chintan Parikh
    I'm on an AMD graphics card. When I use the open source xserver-xorg-video-radeon driver, Gnome shell works fine but my screen resolution can't be set higher than 1024x768. However, when I'm on the closed source fglrx drivers, the screen resolution works fine, but gnome shell doesn't (it goes to gnome classic for some reason). Does anyone know how I can either get gnome shell to work with fglrx, or how I can set my screen resolution with xserver-xorg-video-radeon?
