• Setting Krypton Light to Screen Pixels

  - by Adam Jerrett

  So a few days back, I started playing around with Krypton XNA for 2D lighting in my game. I noticed in general, that spawning a light at (0,0) with Krypton causes the light to appear in, pretty much, the centre of the game screen. Is there any way to change this so a Krypton light's "starting point" at [0,0] would spawn at the top left of the screen, and thus follow the standard screen co-ordinates for position? I ask because currently I'm busy working on my game where my spawn point is [512,512]. With hard code, the closest I've got to the light being "central" to this point is the vector position [12,-20], which makes no sense and is impossible to craft, mathematically, if I want the light to move with the camera (the position [480,512] maps roughly to [10,-20]). So, is there any way to "normalise" the krypton lights to use standard screen co-ordinates? If you guys can, play around with the demo from the site and please see if you can find anything out about it. Documentation on the engine is rather scarce, so it's difficult to find anything relevant to my "pixel-perfect" need. It might just also be something in the code with regards to the matrices that I'm not fully understanding. Any help would be useful. Thanks.

• How do you get better working conditions? [closed]

  - by 0A0D

  I work at a business who has a software side and manufacturing side. The software we write is sold as a package along with other hardware that our customers purchase. I basically work in a warehouse. There is one door that seperates the engineers from the warehouse noise. I have asked for noise cancelling walls to be put in. I have asked multiple times over 6 months to be moved up front to one of two vacant sales offices, but they seem reluctant to let an Engineer move into a sales office. In fact, sales are the only ones with windows and they get commission though they make mistakes or overpromise to the customer. So, my question is how can I get better working conditions without necessarily having to leave my current job? It is very hard to work and concentrate. UPDATE I think I can finally close this chapter in my life. I have moved on to a large corporation which follows CMMI religiously and has even started using Agile in many of its projects. Nevertheless, there is organization, respect, and genuine care for the engineers and scientists that work for them. Pierre was right - quitting was the right answer. My life does not nearly have the amount of stress it used to have because I now work for a place that is organized and knows what it wants its engineers to do along with treating them like they should be treated.

• Reacting to rectangle on rectangle collisions

  - by mcjohnalds45

  I don't know how to react to collisions between two axis aligned rectangles that have x, y, width and height values (x and y are from the centre of the box) to make them simply not overlap. I figured I'd just make them move away from each other depending on how far they intersect in the opposite direction (left, right, up or down) of where they collided. If I check for collisions only on the x axis or only on the y axis it works fine, but when checking for both collisions crazy stuff happens. This code executes when the first box collides with the second. It's in lua but feel free to answer in anything that isn't to too counter-intuitive. if box1.x < box2.x then box1.x = box1.x + box2.x - box1.x - (box1.width / 2) - (box2.width / 2) end if box1.x > box2.x then box1.x = box1.x - (box1.x - box2.x - (box1.width / 2) - (box2.width / 2)) end if box1.y < box2.y then box1.y = box1.y + box2.y - box1.y - (box1.height / 2) - (box2.height / 2) end if box1.y > box2.y then box1.y = box1.y - (box1.y - box2.y - (box1.height / 2) - (box2.height / 2)) end

• Is there such a thing as "closure" with software work?

  - by Bobby Tables

  I burned out last year (after a decade of fulltime programming jobs) and am on a sabbatical now. With all the self-examination I've started to figure out some of the root causes of my burnout, and one of the major ones is basically this: there was never any real closure in any of the work I've ever done. It was always a case of getting into an open-ended support/maintenance grind and going stale. When I first entered the industry, I had this image of programming work being very project-based. And I expected projects to have a start, beginning, and END. And then you move on and start on something totally new and fresh. Basically I never expected that a lot (most) of software work involves supporting and maintaining the same code base for open-ended long periods of time - years and even decades. That, combined with generally having itchy feet makes me think that burnout is inevitable for me, after 2-3 years, in ANY fulltime software job. All this sounds like I probably should have been a contractor instead of a fulltimer. But when I discuss this with people, a lot of them say that even THEN you can't really escape having to go back and maintain/support the stuff you worked on, over and over (eg. Coming back on support contracts, for example). The nature of software work is simply like that. There is no project closure, unlike in many other engineering fields. So my question is - Is there ANY programming work out there which is based on short to mid term projects/stints and then moving on cleanly? And is there any particular industry domain or specialization where this kind of project work is typical?

• Writing Web "server less" applications

  - by crodjer

  TL;DR What are the prospects of write applications which are completely based on a REST database server (CouchDB) and web applications which directly access the DB instead of having a web server in between? I recently started looking up some NoSQL databases. MongoDB seems to be a popular choices. I also liked the project. But I personally liked the REST interface of CouchDB. So what I wanted to know is if there was the possibility of applications (maybe cached apps in web browser, a chrome extension etc.) which could just just query the database directly with no requirement of a webserver in between. All the computational logic would reside in the client application and the database will do what it does, CRUD. Since mostly (I don't know which doesn't) client frameworks support REST quaries, it could be a good way writing applications well optimized for respective framework. These applications though won't be doing complicated computation, but still provide enough functionality which could replace lots of conventional applications. Are existing resources and projects which would help me move towards writing such applications and also the scope and moving towards developing in this way? Are their any technical/security issues with this? This post will help me decide to look into project like CouchDB (and maybe Dive into Erlang later) or stay with the conventional frameworks (like django) and SQL databases. Update A specific point of such apps I had in mind is creation of offline applications just by replicating couchdb data on client.

• Turn-based Client-Server Card Game - Unicast (TCP) or Multicast (UDP)

  - by LDM91

  I am currently planning to make a card game project where the clients will communicate with the server in a turn-based and synchronous manner using messages sent over sockets. The problem I have is how to handle the following scenario: (Client takes it turn and sends its action to server) Client sends a message telling the server its move for the turn (e.g. plays the card 5 from its hand which needs to placed onto the table) Server receives messages and updates game state (server will hold all game state). Server iterates through a list of connected clients and sends a message to tell of them change in state Clients all refresh to display the state This is all based on using TCP, and looking at it now it seems a bit like the Observer pattern. The reason this seems to be an issue to me is this message doesn't seem to be point-to-point like the others as I want to send it to all the clients, and doesn't seem very efficient sending the same message in that way. I was thinking about using multicasting with UDP as then I could send the message to all the clients, however wouldn't this mean that the clients would in theory be able to message each other? There is of course the synchronous aspect as well, though this could be put on top of the UDP I guess. Basically, I would like to know what would be good practice as this project is really all about learning, and even though it won't be big enough to encounter performance issues from this I would like to consider them anyway. However, please note I am not interested in using message oriented middleware as a solution (I have experience with using MOM and I'm interested in considering other options excluding MOM if TCP sockets is a bad idea!).

• GNOME changes to KDE on Maverick

  - by Pit

  Hi, I recently made a clean/fresh install of Ubuntu 10.10 an experienced the problem that the theme changes from Gnome to KDE and back randomly and partly. Sometimes after starting my computer I will have a KDE theme. If I then open the Appearance Preferences ( System - Preferences - Appearance ) some applications and the main-menu as well as menu of applications (only upper two centimetres of a application window) will change back to Gnome only by opening it, not changing anything nor saving. I did not choose KDE at any time, nor did I do any changes to the appearance prior to the first occurrence of this bug. On a second computer I updated from 10.04 to 10.10 and experienced the same bug. On this computer I did however change the layout of the minimize;maximise;close buttons by following How do I move the Window buttons from left to right?. But I don't see how this could provoke the bug, especially as it occurs on a second computer. Will doing updates I saw that there a quite a lot of KDE packages being downloaded. Do I even need those if I don't want to use KDE?

• Control convention for circular movement?

  - by Christian

  I'm currently doing a kind of training project in Unity (still a beginner). It's supposed to be somewhat like Breakout, but instead of just going left and right I want the paddle to circle around the center point. This is all fine and dandy, but the problem I have is: how do you control this with a keyboard or gamepad? For touch and mouse control I could work around the problem by letting the paddle follow the cursor/finger, but with the other control methods I'm a bit stumped. With a keyboard for example, I could either make it so that the Left arrow always moves the paddle clockwise (it starts at the bottom of the circle), or I could link it to the actual direction - meaning that if the paddle is at the bottom, it goes left and up along the circle or, if it's in the upper hemisphere, it moves left and down, both times toward the outer left point of the circle. Both feel kind of weird. With the first one, it can be counter intuitive to press Left to move the paddle right when it's in the upper area, while in the second method you'd need to constantly switch buttons to keep moving. So, long story short: is there any kind of existing standard, convention or accepted example for this type of movement and the corresponding controls? I didn't really know what to google for (control conventions for circular movement was one of the searches I tried, but it didn't give me much), and I also didn't really find anything about this on here. If there is a Question that I simply didn't see, please excuse the duplicate.

• Java Road Trip: Code to Coast (#javaroadtrip)

  - by Justin Kestelyn

  Hey, have you heard? The Java Road Trip bus may be stopping at a city near you this summer, starting June 14. And your peeps at Oracle Technology Network have donated some goodies. What is the Java Road Trip? Basically, we have packed a rock-star bus with demos (Java FX, Oracle ADF, Java EE 6, JDK 7, GlassFish, Java ME) and are putting it on the road; it will make 20 stops across the U.S. in the next couple of months (and MAY may make a special appearance at JavaOne, if we can find a big enough parking space). In many cases these stops will coincide with Java or Oracle user group meet-ups and will always involve beer, food, and free stuff. Furthermore, engineers from HQ will be flying out at various times to rendezvous with these meet-ups and answer your questions. Also, because this tour will only reach a relatively small number of people, we're working hard to provide a virtual experience: there will be a blogger/videographer/photog/tweeter on board, reporting on its every move. You'll find all this content at java.com/roadtrip, and you can get real-time updates via @java. And this new update: If you're attending ODTUG Kaleidoscope in Washington, D.C., in late June, you'll get a chance to see the Java Bus in all its glory. And don't forget your t-shirt, cup, and screen cleaner, all provided by Oracle Technology Network.

• Ubuntu 12.04 Faster boot, Hibernate & other questions

  - by Samarth Shukla

  I've recently started exploring Ubuntu (my 1st distro). I fresh installed precise without a swap (4GB ram). The only issues are, slow boot (regardless of the swap) and instability after a few days of installation. The runtime performance is immaculate otherwise. Even though not needed, I still set swappiness = 10. I've tried the quiet splash profile to GRUB; already have preload installed. But it still is pretty slow. I am not too confident on recompiling the kernel yet. But you could please advice me on that too. I've also added the following to fstab: #Move /tmp to RAM: tmpfs /tmp tmpfs defaults,noexec,nosuid 0 0 (Also if you could please tell me the exact implication/scope of this tweak on physical ram & the swap.) But nothing has happened really. So what alternatives are there to make it boot faster? Also, right after fresh install, though no swap partition, the system still showed /dev/zram0 of arond 2GB which was never used (probably because of the above fstab edit). Finally, I experimented with Hibernate a little, but many claim that it doesn't work on 12.04. (Not to mention, I made a swap file of 4GB for it). What I did was: sudo gedit /var/lib/polkit-1/localauthority/50-local.d/hibernate.pkla Then I added the following lines, saved the file, and closed the text editor: [Re-enable Hibernate] Identity=unix-user:* Action=org.freedesktop.upower.hibernate ResultActive=yes I also edited the upower policy for hibernate: gksudo gedit /usr/share/polkit-1/actions/org.freedesktop.upower.policy I added these lines: < allow_inactive >no< /allow_inactive > < allow_active >yes< /allow_active > But it did not work. So is there an alternate method perhaps that can make it work on 12.04?

• 4 Places To Find Up-To-Date Antivirus Test Results Online

  - by Chris Hoffman

  Everyone wants to be using the best antivirus and wants to know how they perform, so a list of places you can find this information would be useful. It’s not really reasonable to do any testing yourself; way too time-consuming. x places you can find antivirus test results – av comparatives, av test, http://www.westcoastlabs.com/realTimeTesting/article/?articleID=1   Do you know how effective your antivirus programs is? A variety of organizations regularly compare antivirus programs, throwing a large amount of malware samples at them, seeing how they perform, and ranking them in comparison to each other. It would be very time-consuming to test 30 different antivirus programs in virtual machines with a large amoutn of malware samples yourself, which is why these test results are so useful.

• SDL mouse wheel not picking up

  - by Chris

  Running Ubuntu 11.04, SDL 1.2 trying to pickup mouse wheel up/down movement with this (stripped down) code: int main( int argc, char **argv ) { SDL_MouseButtonEvent *mousebutton = NULL; while ( !done ) { if(mousebutton != NULL && mousebutton->button == SDL_BUTTON_LEFT) yrot += 0.75f; else if(mousebutton != NULL && mousebutton->button == SDL_BUTTON_RIGHT) yrot -= 0.75f; else if(mousebutton != NULL && mousebutton->button == SDL_BUTTON_WHEELUP){ xrot += 0.75f; }else if(mousebutton != NULL && mousebutton->button == SDL_BUTTON_WHEELDOWN){ xrot -= 0.75f; } while ( SDL_PollEvent( &event ) ) { switch( event.type ) { case SDL_MOUSEBUTTONDOWN: mousebutton = &event.button; break; case SDL_MOUSEBUTTONUP: mousebutton = NULL; break; default: break; } } } return 0; } strange thing is, scrolling with the mouse button does nothing, but if I hold down a mouse button or two and then move the mouse it hits the SDL_BUTTON_WHEEL code occasionally. This honestly reeks of a pointer issue, which would make sense since I've been spoiled with C# for the past couple years, but I am just not seeing it. How do i correctly find mouse scroll events in SDL?

• Saving Dragged Dropped items position on postback in asp.net [closed]

  - by Deeptechtons

  Ok i saw many post's on how to serialize the value of dragged items to get hash and they tell how to save them. Now the question is how do i persist the dragged items the next time when user log's in using the has value that i got eg: <ul class="list"> <li id="id_1"> <div class="item ui-corner-all ui-widget ui-widget-content"> </div> </li> <li id="id_2"> <div class="item ui-corner-all ui-widget ui-widget-content"> </div> </li> <li id="id_3"> <div class="item ui-corner-all ui-widget ui-widget-content"> </div> </li> <li id="id_4"> <div class="item ui-corner-all ui-widget"> </div> </li> </ul> which on serialize will give "id[]=1&id[]=2&id[]=3&id[]=4" Now think that i saved it to Sql server database in a single field called SortOrder. Now how do i get the items to these order again ? the code to make these sort is below,without which people didn't know which library i had used to sort and serialize <script type="text/javascript"> $(document).ready(function() { $(".list li").css("cursor", "move"); $(".list").sortable(); }); </script>

• How to capture a Header or Trailer Count Value in a Flat File and Assign to a Variable

  - by Compudicted

  Recently I had several questions concerning how to process files that carry a header and trailer in them. Typically those files are a product of data extract from non Microsoft products e.g. Oracle database encompassing various tables data where every row starts with an identifier. For example such a file data record could look like: HDR,INTF_01,OUT,TEST,3/9/2011 11:23 B1,121156789,DATA TEST DATA,2011-03-09 10:00:00,Y,TEST 18 10:00:44,2011-07-18 10:00:44,Y B2,TEST DATA,2011-03-18 10:00:44,Y B3,LEG 1 TEST DATA,TRAN TEST,N B4,LEG 2 TEST DATA,TRAN TEST,Y FTR,4,TEST END,3/9/2011 11:27 A developer is normally able to break the records using a Conditional Split Transformation component by employing an expression similar to Output1 -- SUBSTRING(Output1,1,2) == "B1" and so on, but often a verification is required after this step to check if the number of data records read corresponds to the number specified in the trailer record of the file. This portion sometimes stumbles some people so I decided to share what I came up with. As an aside, I want to mention that the approach I use is slightly more portable than some others I saw because I use a separate DFT that can be copied and pasted into a new SSIS package designer surface or re-used within the same package again and it can survive several trailer/footer records (!). See how a ready DFT can look: The first step is to create a Flat File Connection Manager and make sure you get the row split into columns like this: After you are done with the Flat File connection, move onto adding an aggregate which is in use to simply assign a value to a variable (here the aggregate is used to handle the possibility of multiple footers/headers): The next step is adding a Script Transformation as destination that requires very little coding. First, some variable setup: and finally the code: As you can see it is important to place your code into the appropriate routine in the script, otherwise the end result may not be as expected. As the last step you would use the regular Script Component to compare the variable value obtained from the DFT above to a package variable value obtained say via a Row Count component to determine if the file being processed has the right number of rows.

• Finding header files

  - by rwallace

  A C or C++ compiler looks for header files using a strict set of rules: relative to the directory of the including file (if "" was used), then along the specified and default include paths, fail if still not found. An ancillary tool such as a code analyzer (which I'm currently working on) has different requirements: it may for a number of reasons not have the benefit of the setup performed by a complex build process, and have to make the best of what it is given. In other words, it may find a header file not present in the include paths it knows, and have to take its best shot at finding the file itself. I'm currently thinking of using the following algorithm: Start in the directory of the including file. Is the header file found in the current directory or any subdirectory thereof? If so, done. If we are at the root directory, the file doesn't seem to be present on this machine, so skip it. Otherwise move to the parent of the current directory and go to step 2. Is this the best algorithm to use? In particular, does anyone know of any case where a different algorithm would work better?

• Methodology To Determine Cause Of User Specific Error

  - by user3163629

  We have software that for certain clients fails to download a file. The software is developed in Python and compiled into an Windows Executable. The cause of the error is still unknown but we have established that the client has an active internet connection. We suspect that the cause is due to the clients network setup. This error cannot be replicated in house. What technique or methodology should be applied to this kind of specific error that cannot be replicated in house. The end goal is to determine the cause of this error so we can move onto the solution. For example; Remote Debugging: Produce a debug version of the software and ask the client to send back a debug output file. This involves alot of time (back and forth communication) and requires the client to work and act in a timely manor to be successful. In-house debugging: Visit the client and determine their network setup, etc. Possibly develop a series of script tests before hand to run on the clients computer under the same network. Other methodologies and techniques I am not aware of?

  i would have to elaborate my questions so please have patience Explaining the logic. if you are familiar with logmein then it installs a client software on your computer then it kinda keeps tracks where you computer is as long as it's connected to internet. So you can always access your computer no matter where it is whatever it's IP is you just go to logmein.com and then you can just access it. Now what i am asking 1. Let's assume i have a website hosted on my laptop let's call it webserver. so then i move around i have a new IP sometime even on a hotel network is it possible to do something like what logmein does so i can keep moving around my Webserver to new IP but it has some local client or something which keeps updating my IP or something i am sure i would need a gateway server somewhere which is connected to my domain name via DNS so somebody accessing my website www.mywebsite.com goes to my main server then gets routed to my laptop which could be anywhere but my gateway server is able to communicate to my webserver I will keep updating the case description based on comments to make more sense. please have patience with me. Regards

• Problem Installing Ubuntu 12.04 - [Errno 5]

  - by Rob Barker

  I'm trying to intall Ubuntu 12.04 to my brand new eBay purchased hard drive. Only got the drive today and already it's causing me problems. The seller is a proper proffesional company with 99.9% positive feedback, so it seems unlikely they would have sold me something rubbish. My old hard drive packed up last Tuesday and so i bought a new one to replace it. Because this was an entirely new drive i decided to install Ubuntu as there was no current operating system. My computer is an eMachines EM250 netbook. There's no disc drive so i am installing from a USB stick. The new operating system loads beautifully, and the desktop appears just as it should. When i click install i am taken to the installer which copies the files to about 35% and then displays this: [Errno 5] Input/output error This is often due to a faulty CD/DVD disk or drive, or a faulty hard disk. It may help to clean the CD/DVD, to burn the CD/DVD at a lower speed, to clean the CD/DVD drive lens (cleaning kits are often available from electronics suppliers), to check whether the hard disk is old and in need of replacement, or to move the system to a cooler environment. The hard drive can be heard constantly crackling. When i booted Ubuntu 12.04 from my old faulty hard drive as a test, i didn't even make it past the purple Ubuntu screen, so it can't be that bad. Any ideas? Message to the moderators. Please do not close this thread. I'm well aware there may be other threads on this, but i don't want it closing as the others do not provide the answer i am looking for. Thank you.

• Financial institutions build predictive models using Oracle R Enterprise to speed model deployment

  - by Mark Hornick

  See the Oracle press release, Financial Institutions Leverage Metadata Driven Modeling Capability Built on the Oracle R Enterprise Platform to Accelerate Model Deployment and Streamline Governance for a description where a "unified environment for analytics data management and model lifecycle management brings the power and flexibility of the open source R statistical platform, delivered via the in-database Oracle R Enterprise engine to support open standards compliance." Through its integration with Oracle R Enterprise, Oracle Financial Services Analytical Applications provides "productivity, management, and governance benefits to financial institutions, including the ability to: Centrally manage and control models in a single, enterprise model repository, allowing for consistent management and application of security and IT governance policies across enterprise assets Reuse models and rapidly integrate with applications by exposing models as services Accelerate development with seeded models and common modeling and statistical techniques available out-of-the-box Cut risk and speed model deployment by testing and tuning models with production data while working within a safe sandbox Support compliance with regulatory requirements by carrying out comprehensive stress testing, which captures the effects of adverse risk events that are not estimated by standard statistical and business models. This approach supplements the modeling process and supports compliance with the Pillar I and the Internal Capital Adequacy Assessment Process stress testing requirements of the Basel II Accord Improve performance by deploying and running models co-resident with data. Oracle R Enterprise engines run in database, virtually eliminating the need to move data to and from client machines, thereby reducing latency and improving security"

• HTG Explains: Which Linux File System Should You Choose?

  - by Justin Garrison

  File systems are one of the layers beneath your operating system that you don’t think about—unless you’re faced with the plethora of options in Linux. Here’s how to make an educated decision on which file system to use. The landscape of the Linux file system support is drastically different from Windows and OS X. In Windows and OS X you can find software that will add support for non-standard file systems, but both operating systems can only be installed on their native file system and third party support is added after the fact. Linux on the other hand has a vast array of supported file systems built into the kernel. But how are you supposed to know which file system to pick when installing? We will take a look at some of the most popular choices available and give you use cases to consider—the choice is ultimately up to you based on your needs.

• Hydraulics in game

  - by Mungoid

  I'm not completely sure if this would be better in the Physics site or not as this question is more about how hydraulics should work in game as opposed to how they really work (although that is taken into account) - So I apologize if this is in the wrong place. A project we are on, we have a machine with hydraulics that are powered (They don't just look like they move something, they are the only thing moving/turning/lifting something) - However, the hydraulic extends the same speed no matter what it is pushing. So, say there is a 10 ton object attached to one end of the hydraulic and the other end is attached to a plate on the ground. In real life it takes a few seconds to build up pressure depending on how heavy the object is, but in our project the hydraulics don't care about that. It will lift a 100 ton object the same speed as a 10 ton object. We have a way to fake the hydraulic pressurizing by reducing the 'drive amount' (how fast or slow the hydraulic extends) when we sense that it is touching the ground and that does a relatively decent job but we would like to be able to take other things into account like engine speed, ratios, loads, etc. but we aren't too sure what we need to think about. I'm kinda wondering if anyone here has any experience with this and could offer some suggestions on what to take into account?

• Java Slick2d - Mouse picking how to take into account camera

  - by Corey

  When I move it it obviously changes the viewport so my mouse picking is off. My camera is just a float x and y and I use g.translate(-cam.cameraX+400, -cam.cameraY+300); to translate the graphics. I have the numbers hard coded just for testing purposes. How would I take into account the camera so my mouse picking works correctly. double mousetileX = Math.floor((double)mouseX/tiles.tileWidth); double mousetileY = Math.floor((double)mouseY/tiles.tileHeight); double playertileX = Math.floor(playerX/tiles.tileWidth); double playertileY = Math.floor(playerY/tiles.tileHeight); double lengthX = Math.abs((float)playertileX - mousetileX); double lengthY = Math.abs((float)playertileY - mousetileY); double distance = Math.sqrt((lengthX*lengthX)+(lengthY*lengthY)); if(input.isMousePressed(Input.MOUSE_LEFT_BUTTON) && distance < 4) { if(tiles.map[(int)mousetileX][(int)mousetileY] == 1) { tiles.map[(int)mousetileX][(int)mousetileY] = 0; } } That is my mouse picking code

• Data Center Modernization: Harness the power of Oracle Exalogic and Exadata with PeopleSoft

  - by Michelle Kimihira

  Author: Latha Krishnaswamy, Senior Manager, Exalogic Product Management   Allegis Group - a Hanover, MD-based global staffing company is the largest privately held staffing company in the United States with more than 10,000 internal employees and 90,000 contract employees. Allegis Group is a $6+ billion company, offering a full range of specialized staffing and recruiting solutions to clients in a wide range of industries.   The company processes about 133,000 paychecks per week, every week of the year. With 300 offices around the world and the hefty task of managing HR and payroll, the PeopleSoft system at Allegis  is a mission-critical application. The firm is in the midst of a data center modernization initiative. Part of that project meant moving the company's PeopleSoft applications (Financials and HR Modules as well as Custom Time & Expense module) to a converged infrastructure.     The company ran a proof of concept with four different converged architectures before deciding upon Exadata and Exalogic as the platform of choice.   Performance combined with High availability for running mission-critical payroll processes drove this decision.  During the testing on Exadata and Exalogic Allegis applied a particular (11-F) tax update in production environment. What job ran for roughly six hours completed in less than 1.5 hours. With additional tuning the second run of the Tax update 11-F reduced to 33 minutes - a 90% improvement!     Not only that, the move will help the company save money on middleware by consolidating use of Oracle licensing in a single platform.   Summary With a modern data center powered by Exalogic and Exadata to run mission-critical PeopleSoft HR and Financial Applications, Allegis is positioned to manage business growth and improve employee productivity. PeopleSoft applications run on engineered systems platform minimizing hardware and software integration risks.
