• My father is a doctor. He is insisting on writing a database to store non-critical patient information, with no programming background

  - by Dominic Bou-Samra

  So, my father is currently in the process of "hacking" together a database using FileMaker Pro, a GUI based databasing tool for his small (4 doctor) practice. The database will be used to help ease the burden on reporting from medical machines, streamlining quite a clumsy process. He's got no programming background, and seems to be doing everything in his power to not learn things correctly. He's got duplicate data types, no database-enforced relationships (foreign/primary key constraints) and a dozen other issues. He's doing it all by hand via GUI tool using Youtube videos. My issue is, that whilst I want him to succeed 100%, I don't think it's appropriate for him to be handling these types of decisions. How do I convince him that without some sort of education in these topics, a hacked together solution is a bad idea? He's can be quite stubborn and I think he sees these types of jobs as "childs play" How should I approach this? Is it even that bad an idea - or am I correct in thinking he should hire a proper DBA/developer to handle this so that it doesn't become a maintenance nightmare? NB: I am a developer consultant of 4 years and I've seen my share of painful customer implementations.

• Is Play Framework good for doing some logic parallely?

  - by pmichna

  I'm going to build a web application that's going to host urban games. A user visits my website, clicks "Start game" and starts receiving some SMS messages when gets to some location and has to answer them to get points. My question: is Play suitable for this kind of application? From what I've read I know for sure it's ok for traditional web applications: user interface for same data storage and manipulation. But what if after clicking the "start button" some logic has to go on its own course? How would I handle parallely checking geolocation of the players (I have API for that)? I guess in some threads that would ping them every ~5 sec. and do some processing but is it possible to just "disconnect" them from the main user interface? So to sum up: I want an application written in Play that starts a separate thread for a game after clicking "start game" and other users are able to view their data (statisctics etc.), while the threads work their way with the game logic. I found something like jobs but they are documented for version 1.2 (current one is 2.2). Sorry for my somewhat fuzzy explenation, I tried to do my best.

• From simple physics with a ball, to a more complicated shape

  - by Maximus

  Hello fellow game devs and stack overflowers... I recently made a transition from OpenGL ES 1.1 to 2.0 (on Android via NDK) and things are going well so far. I'm working on doing a dice rolling application (gaming dice up to 20 sided, not just regular 6 sided die) as a way to learn more about how physics is implemented in a gaming environment. I've explored implementing existing engine options (such as Bullet) and I don't think I need to implement something quite so sophisticated. I've found several tutorials that handle a lot of the general physics involved with initial trajectory, velocity, angle of contact and reflection angle, etc. I'm confident that I'd be able to implement ball-like behavior without much trouble. My question lies in when I attempt to make the interaction of the die shape with another surface more "realistic," for example... the die strikes the floor surface at such an angle where only one corner makes contact with the floor. In my mind, the center of gravity of the object would play a part in determining how the die bounces away, possibly even spinning it it faster, etc... but I am not sure what the actual math involved is. Are there any recommended resources for getting into this level of detail? Initial searches haven't turned up much... Thanks to everyone in the community, -Jeremiah

• How do I account for changed or forgotten tasks in an estimate?

  - by Andrew

  To handle task-level estimates and time reporting, I have been using (roughly) the technique that Steve McConnell describes in Chapter 10 of Software Estimation. Specifically, when the time comes for me to create task-level estimates (right before coding begins on a project), I determine the tasks at a fairly granular level so that, whenever possible, I have no tasks with a single-point, 50%-confidence estimate greater than four hours. That way, the task estimation process helps with constructing the software while helping me not to forget tasks during estimation. I come up with a range of hours possible for each task also, and using the statistical calculations that McConnell describes along with my historical accuracy data, I can generate estimates at other confidence levels when desired. I feel like this method has been working fairly well for me. We are required to put tasks and their estimates into TFS for tracking, so I use the estimates at the percentage of confidence I am told to use. I am unsure, however, what to do when I do forget a task, or I end up needing to do work that does not neatly fall within one of the tasks I estimated. Of course, trying to avoid this situation is best, but how do I account for forgotten/changed tasks? I want to have the best historical data I can to help me with future estimates, but right now, I basically am just calculating whether I made the 50%-confidence estimate and whether I made it inside the ranged estimate. I'll be happy to clarify what I'm asking if needed -- let me know what is unclear.

• App to make a video from photos?

  - by chtfn

  I was wondering what could be a good app (with a GUI ;) ) for making a video from a bunch of photos or images, to create a time-lapse video, or a stop-motion animation, or even a video like this one. The idea is to set a really small time between each photo, but also to be able to change this time every so often, or add some effects, to make the succession smoother in particular. What would be perfect is a function that allows automatic cropping of the photos as well as exposure adjustment so they all have the same background and so the time-lapse video looks smoother. I know about the slide show app "Imagination" but the interval can not go under one second. Cheers! Edit: here is my progress, also thanks to the first answer: I tried Luciole, it is really simple and promessing, but pretty buggy, and I only could export an average video in .dv format (mpg2 and avi don't work). Apparently, it has difficulties when changing the fps. I also tried StopMotion: also pretty buggy, I had to go into preferences and modify the encoding commands to get a result, but it's the best result I got so far. But none of those has effects to make transitions smoother... I tried several diaporama apps: Imagination doesn't handle more than 1 image per second; PhotoFilmStrip (repo version and latest version from website): same problem even though you can go down to 0.1 second per image, it still behaves wierdly (going back to 1 second automatically); Videoporama: doesn't start at all on 12.04. Any other idea, folks?

• Static "LoD" hack opinions

  - by David Lively

  I've been playing with implementing dynamic level of detail for rendering a very large mesh in XNA. It occurred to me that (duh) the whole point of this is to generate small triangles close to the camera, and larger ones far away. Given that, rather than constantly modifying or swapping index buffers based on a feature's rendered size or distance from the camera, it would be a lot easier (and potentially quite a bit faster), to render a single "fan" or flat wedge/frustum-shaped planar mesh that is tessellated into small triangles close to the near or small end of the frustum and larger ones at the far end, sort of like this (overhead view) (Pardon the gap in the middle - I drew one side and mirrored it) The triangle sizes are chosen so that all are approximately the same size when projected. Then, that mesh would be transformed to track the camera so that the Z axis (center vertical in this image) is always aligned with the view direction projected into the XZ plane. The vertex shader would then read terrain heights from a height texture and adjust the Y coordinate of the mesh to match a height field that defines the terrain. This eliminates the need for culling (since the mesh is generated to match the viewport dimensions) and the need to modify the index and/or vertex buffers when drawing the terrain. Obviously this doesn't address terrain with overhangs, etc, but that could be handled to a certain extent by including a second mesh that defines a sort of "ceiling" via a different texture. The other LoD schemes I've seen aren't particularly difficult to implement and, in some cases, are a lot more flexible, but this seemed like a decent quick-and-dirty way to handle height map-based terrain without getting into geometry manipulation. Has anyone tried this? Opinions?

• Design mode in Visual studio 2010 sp1 beta

  - by anirudha

  in MVC3 razor we found that their is no way to watch the design in Visual studio as well we can see aspx file by going to design mode. their is a little trick to solve this issue first is that if you have Expression web or Vs 2008 then open the file on them how see here in expression web 4 you need to add the extension .cshtml and open them as html as we open other. in Visual studio 2008 you need to add the extension .cshtml and set them open as html. well their is no big trouble if design not worked. but in some case when you need to get this issue solved this need to be work for configuration do this: Expression Web 4 > tools > application options > configure editor > click on new extension icon show in exact left put the cshtml in the window they show you and choose expression web [open as html] after that you can see the design in expression web. by default Expression web not have cshtml as known extension so you need to do that to add them because without it they never handle cshtml file and refer them to Visual studio. after setting this you  EW4 open the cshtml file as html and show you design in design mode. in Visual studio 2008 you can use same trick to solve this issue just follow this step > options > text editors > file extension put cshtml in textbox and set the option html editor from dropdown and click on add and ok this will open your cshtml file as html.

• Studentworker - being a superhero?

  - by Niklas H

  A couple of weeks ago I got a new job as a studentworker for a webagency. The job is 15-20 hours of week. Even though I am new in the company, I feel right at home and I enjoy working with my co-workers. To start of with, I was assigned to work on an internal tool in the company, in order to learn their systems and their development platform. The deadline for this project is this week, and I am right on time. But today (wednesday at noon) I received an email from my boss, asking me to do a new project that has a deadline at friday morning. The new assignment alone will be hard to finish on time, and on top of that I need to finish the other assignment on time. My question is: How do I handle my boss expecting me to be a superhero? EDIT: I will talk to my boss about delaying one of the projects. But another problem is that the new assignment will be hard to do on time (friday morning). I didn't have a say on the deadline - I just got a mail telling me the deadline. I am new in the company and want to stay, but I don't want to start off on the wrong foot with the boss.

• How does one rein in the complexities of web development ?

  - by Rahul

  I have been a server-side programmer for most of my career and have only recently started spending more time on web development. I am amazed at the number of things I need to master in order to write a decent web application. Just to list down a few tools/technologies I need to learn, Server side programming language (Java/JSP, ASP, PHP, Ruby or something else) A decent web framework (for any medium to big size application). HTML & CSS Javascript Javascript library (JQuery/ExtJS etc. primarily for AJAX). Good to know even if not necessary. At least a basic knowledge of web design - layouts, colors, fonts etc. A good understanding of web security. A good understanding of Performance/scalability issues. Testing, browser compatibility issues etc. The list goes on. So, my question to seasoned web developers is - How do you guys manage to learn and keep yourself updated on so many things? While developing a web application, how do you handle the complexities involved in these areas and yet manage to write an application that is well designed, user friendly, secure, performant and scalable. As a web developer, does one have to be a jack of all trades or should one specialize in one or two areas and leave the rest to other members of the team ?

• How to design a scriptable communication emulator?

  - by Hawk

  Requirement: We need a tool that simulates a hardware device that communicates via RS232 or TCP/IP to allow us to test our main application which will communicate with the device. Current flow: User loads script Parse script into commands User runs script Execute commands Script / commands (simplified for discussion): Connect RS232 = RS232ConnectCommand Connect TCP/IP = TcpIpConnectCommand Send data = SendCommand Receive data = ReceiveCommand Disconnect = DisconnectCommand All commands implement the ICommand interface. The command runner simply executes a sequence of ICommand implementations sequentially thus ICommand must have an Execute exposure, pseudo code: void Execute(ICommunicator context) The Execute method takes a context argument which allows the command implementations to execute what they need to do. For instance SendCommand will call context.Send, etc. The problem RS232ConnectCommand and TcpIpConnectCommand needs to instantiate the context to be used by subsequent commands. How do you handle this elegantly? Solution 1: Change ICommand Execute method to: ICommunicator Execute(ICommunicator context) While it will work it seems like a code smell. All commands now need to return the context which for all commands except the connection ones will be the same context that is passed in. Solution 2: Create an ICommunicatorWrapper (ICommunicationBroker?) which follows the decorator pattern and decorates ICommunicator. It introduces a new exposure: void SetCommunicator(ICommunicator communicator) And ICommand is changed to use the wrapper: void Execute(ICommunicationWrapper context) Seems like a cleaner solution. Question Is this a good design? Am I on the right track?

• Game Resource Generation

  - by Darthg8r

  I am currently building a game that has a "City" entity. These cities generate and consume resources such as food variably over a period of time. I need to be able query the server often to find exactly how much food the city at any given point. These queries can take place multiple times per minute. There could also be 400,000 cities to track at a given time. How would you handle tracking these resources? Would you do it in real time, keeping an instance of the city in memory on the server, with some sort of a snapshot in time of the resources, then computing the growth/consumption from that snapshot time for subsequent queries? Would you work exclusively with a database, using a similar "snapshoting" scheme? Maybe a mixture of the 2, caching recently queried cities in memory for a period of time? There is also a lot of other data that each city needs to track. A player can queue units to build in a barrack. The armies available in the city will need to be updated as units complete. I'm interested in everyone's input on where/when/how you'd manage the real time data.

• Architectural and Design Challenges with SOA

  With all of the hype about service oriented architecture (SOA) primarily through the use of web services, not much has been said about potential issues of using SOA in the design of an application. I am personally a fan of SOA, but it is not the solution for every application. Proper evaluation should be done on all requirements and use cases prior to deciding to go down the SOA road. It is important to consider how your application/service will handle the following perils as it executes. Example Challenges of SOA Network Connectivity Issues Handling Connectivity Issues Longer Processing/Transaction Times How many of us have had issues visiting our favorite web sites from time to time? The same issue will occur when using service based architecture especially if it is implemented using web services. Forcing applications to access services via a network connection introduces a lot of new failure points to the application. Potential failure points include: DNS issues, network hardware issues, remote server issues, and the lack of physical network connections. When network connectivity issues do occur, how are the service clients are implemented is very important. Should the client wait and poll the service until it is accessible again? If so what is the maximum wait time or number of attempts it should retry. Due to the fact of services being distributed across a network automatically increase the responsiveness of client applications due to the fact that processing time must now also include time to send and receive messages from called services. This could add nanoseconds to minutes per each request based on network load and server usage of the service provider. If speed highly desirable quality attribute then I would consider creating components that are hosted where the client application is located. References: Rader, Dave. (2002).

• Very Cool &ndash; Miami 311 System for tracking citizen service requests (Windows Azure, Silverlight

  - by Jim Duffy

  Having grown up in South Florida this short, but very enlightening, video explaining how the City of Miami has implemented a 311 citizen service request system using Windows Azure, Silverlight and Bing Maps definitely caught my attention. Miami311 The Miami311 System is a Windows Azure/Silverlight-based solution which enables City of Miami citizens report and track issues reported to city management. The system uses Bing Maps to plot the location and relevant information about each issue reported. Citizens now have the ability to easily see the status of the issue without having to call the city office. What I found interesting were a couple of benefits that a metropolitan area such as Miami can take advantage of in Windows Azure cloud-based solution. For the city of Miami, both benefits center around the weather. Of course the threat of a hurricane is a real issue in South Florida and what better way to make sure your site stays up during a hurricane then to have the site hosted far away from the eye of the storm. Using a Windows Azure cloud-based architecture the City of Miami is able to host the application within the Microsoft data centers safely away from any hurricane passing through South Florida. The second benefit is the inherent scalability of a Windows Azure based solution. During a severe weather event like thunderstorms or even worse, a hurricane, downed trees and power lines are a commonly reported problem. Being able to quickly scale up the computing resources required to handle the spike in citizens reporting these types of problems on the site is a huge benefit. Once the weather event has passed and downed tree reports begin to subside they can quickly reverse the process and scale the system back down to pre-storm levels. It’s kind of day-to-day kind of stuff but very cool stuff nonetheless. Have a day. :-|

• Entity Component System for HUD and GUI

  - by Jason L.

  This is a very rough sketch of how I currently have things designed. It should, at least, give an idea of how my ECS is currently designed. If you notice in that diagram, I have basically split the HUD out of the ECS. They have their own set of things (HudLayer, HudComponent, etc) and are handled differently. This is where I'm struggling, though. There are many different instances in which the HUD will need to know about entities. Not just data changing (I have an event dispatcher for that), but the actual entity and all it encompasses. There are also situations where entities will need to be able to query the HUD for data. Let's take a couple examples: First, my equipment screen. On here I can change the equipment on a character (Entity). In order for this to happen, I need to know about the entity. At least I think I do? How can I handle this? The second scenario involves my Systems needing to query a HudComponent for data. A specific example would be my battle system. Each "team" is given a 3x3 grid they can move around in. See here: Skills target these cells, and not the player, so I would need a way for my systems to determine which cells are occupied and which are not. Basically I need a way for two way communication between Systems and my HUD. I know it's recommended (by some people, anyways) to take your HUD out of the ECS. Is that appropriate in my case?

• How to prevent multiple playing sounds from destroying your hearing?

  - by Rookie

  The problem is that when I play 100 sounds almost at same time, all I hear is noise. It's not very attractive to listen it for 30 minutes straight. I tried to fix this by allowing only 1 sound of each sound type to be played at once. But it still sounds really ugly; eventually my brain keeps hearing only the very end of the shot sounds (or the start of it?), and that gets on my nerves really quickly. Eventually I would just decide to turn off the sounds completely. So is there any point of using sounds in a game like this at all? How does our dear reality handle this problem? If there is a war out there, how does it sound when hundred of men shoot almost at the same times? Edit: Here is how the game sounds currently; there isn't even 100 sounds playing at once, maybe 20? http://www.speedyshare.com/VTBDw/headache.mp3 At the beginning it sounds OK, but then it becomes unbearable! In that audio clip there is allowed only 1 sound to be played at once, so it will stop the previous playing sound when new sound is played. Edit2: And here is same headache but 32 simultaneous sounds allowed to be played at same time: http://www.speedyshare.com/TuWAR/headache-worse.mp3 Quite a torture, eh?

• Which one is better offline method for large scale application

  - by Manish Pansiniya

  We've a big data management website used by several property. Some of our customers have downtime (they can't access net for an hour or two). We want our site to support offline data viewing and inventory management (typical data search and add/remove) and when the user goes online we can sync the changes back to our central database. Customers use several platforms like Windows, iOS, etc. We've been looking into several different options, here are the major choices - Develop offline web app supported in HTML5. Develop a 'fallback' mechanism and interact with data from the app cache as explained in here (http://www.htmlgoodies.com/html5/tutorials/introduction-to-offline-web- applications-using-) Develop a desktop based cross platform solution. I remember the old MONO which has been popular. Here's a post (What do you suggest for cross platform apps, including web cross-platform-apps-including-web) and another one (Technology choice for cross platform development (desktop and phone)? platform-development-desktop-and-phone?rq=1) I realize the the desktop solution might be hard to maintain and result in some compatibility issues and demand test environments. Can HTML5 handle moderate to high level complexity and data flow? Or would it be better to rely on a desktop based app for better scalability & performance?

• ClearTrace Supports Statement Level Events

  - by Bill Graziano

  One of the requests I get on a regular basis is to capture the performance of statement level events.  The latest beta has this feature available.  If you’re interested in this I’d like to get some feedback. I handle the SP:StmtCompleted and the SQL:StmtCompleted events.  These report CPU, reads, writes and duration. I’m not in any way saying it’s a good idea to trace these events.  Use with caution as this can make your traces much larger. If there are statement level events in the trace file they will be processed.  However the query screen displays batch level *OR* statement level events.  If it did both we’d be double counting. I don’t have very many traces with statement completed events in them.  That means I only did limited testing of how it parses these events.  It seems to work well so far though.  Your feedback is appreciated. If you ever write loops or cursors in stored procedures you’re going to get huge trace files.  Be warned. I also fixed an annoying bug where ClearTrace would fail and tell you a value had already been added.  This is a result of the collection I use being case-sensitive and SQL Server not being case-sensitive.  I thought I had properly coded around that but finally realized I hadn’t.  It should be fixed now. If you have any questions or problems the ClearTrace support forum is the best place for those.

• 12.04 LTS boot hangs at "SP5100 TCO timer: mmio address 0xfec000f0 already in use", didn't yesterday

  - by DarkIron112

  Dual-booting Windows 7 and Ubuntu 12.04 LTS. I went to reboot from Win to Ubu, and found a few interesting things. My POST screen is covered in blocks of epileptic colors until I hit GRUB, which continues when I try to boot into Ubuntu. These color blocks don't appear when I use my on-board VGA, so I'll just attribute to that. Grub dimensions are swapped (card vs onboard, probably), but, when interfacing with onboard VGA, the Grub Timeout Counter works and when using my card, it does not (see "[!!!]" below for more information) Booting into Ubuntu directly causes the error: SP5100 TCO timer: mmio address 0xfec000f0 already in use Booting into recovery mode, meanwhile, and then "resuming normal boot" gets me to the desktop without native 1440x900 resolution and graphic drivers can't tell the monitor it's looking at (I assume this is because it's not a full graphic boot, and as it says, some drivers won't run?) [!!!] When I reboot after going into recovery mode, the countdown timer works ONCE, puts me back into default ubuntu boot, and then does not work again until after another recovery-mode boot. Windows 7 can boot perfectly with no issues whatsoever from epilepsy color blocks or driver detection. This makes me wonder /why/ the POST screen can't handle my video card anymore. Amidst all the diagnostics, I opened my case and re-seated the videocard securely, ensuring it wasn't a loose connection-- But this did nothing to help me. Hardware I am running an NVidia GeForce GTX 8800 video card in a PCI slot. I have 4.8GiB memory, an AMD Athlon II Quad-core 640 Processor, on an MSI K9N6GM Series Mobo. Onboard video is an NVidia GeForce MCP61(V/S/P) card. Note: I did not have any of these problems yesterday, and I have been using Ubuntu intensively for a week, though it's been working flawlessly for months. I've recently been using it to mod my Android phone, perhaps I messed something up in the file system?

• Going on 15 months for me...

  - by Ratman21

  About 5 face to face interviews, 4 telephone ones and except for the two weeks Census Job. But, after 15 months looking for work, I am still with out a JOB. What is wrong here or with me? Let’s see, hard worker (check), self motivated to do well on a Job (Check), Certified CompTIA A+, Security+  and Network+ Technician (Check), 20 + years experience in “IT” (CHECK), in good health, in 20 years of work only 15 days off due to health issues (Check), 18 years experience as technical Help Desk support (Check), can still work better than younger personal (Check), Strong trouble shooting skills for software, computer hard ware and circuit issues (Check) and Multiple software languages (Hey I have done some programming) Check. Hmm I don’t see any problem with me (of course I could have missed something, please let me know if you see what I am missing).    Now as to what have I been up to since I last blogged. The same things of course, Job hunting, job hunting and study.   I have set up sim of my home LAN and will be adding a wireless print server to the sim and in real life, soon.  I was able to pull up and copy the examples of Cisco router commands that I had on my old lap top, to my newer PC. Every time I used a new command while working the NOC on my last job.   I would cut and past a copy of the command on the router (and what it did) I was working on.  Along with notes on the problem and commands use for same router. I used these to make documentation for on how to handle these types of issues, for the other Operation Techs. My old notes are helping me in studying for the CCENT test.    As to Love Dare, I think it will take more like 40 weeks, than the 40 days of the book. Yes I am making progress, slow but, it is progress. I will have more on that in my next blog.

• How do I start Ubuntu without X server?

  - by Kaare Mikkelsen

  So, I'm trying to install the official nVidia drivers for my fancy graphics card, and they advice disabling the X server before installing, as well as making sure that I can boot without the X server, so as not to wreck anything. However, I seem to be doing something wrong. As I understand it, this should be as simple as changing the runlevel from 2 to 1? (I am aware that all this may simply be me not understanding runlevels) If that is correct, a quick test should be simply typing "sudo init 1" or "sudo telinit 1" in a terminal? Doing that makes the system attempt to shutdown, only it stops at the purple screen with the ubuntu logo and 5 white dots underneath. I haven't observed it get anywhere from there, I always end up holding down the power button. "sudo telinit 3" has not visible effect. Alternatively, I should be able to get there using the recovery mode, activated through the grub menu? I have very little success with that. After picking recovery mode, I am faced with a set of options about how to proceed. Both choosing the one with "network enabled" and "text only", I get a dialog explaining that this will mount my / file system in read/write mode, and whether this is what I want. I choose yes, and it seems to report that my drive is fine (there's a single line of text detailing the state of the partition). And then it stops. I haven't tried letting it sit for more than a few minutes, but presumably this process should be comparable in duration to a regular boot? I am not particularly fond of messing with any .conf-files until I am certain that I can handle things with training wheels on. So, I guess there are two questions: the one in the title, and "how do I start a text-only session without changing defaults?" Thanks in advance :)

• Unity - Invert Movement Direction

  - by m41n

  I am currently developing a 2,5D Sidescroller in Unity (just starting to get to know it). Right now I added a turn-script to have my character face the appropriate direction of movement, though something with the movement itself is behaving oddly now. When I press the right arrow key, the character moves and faces towards the right. If I press the left arrow key, the character faces towards the left, but "moon-walks" to the right. I allready had enough trouble getting the turning to work, so what I am trying is to find a simple solution, if possible without too much reworking of the rest of my project. I was thinking of just inverting the movement direction for a specific input-key/facing-direction. So if anyone knows how to do something like that, I'd be thankful for the help. If it helps, the following is the current part of my "AnimationChooser" script to handle the turning: Quaternion targetf = Quaternion.Euler(0, 270, 0); // Vector3 Direction when facing frontway Quaternion targetb = Quaternion.Euler(0, 90, 0); // Vector3 Direction when facing opposite way if (Input.GetAxisRaw ("Vertical") < 0.0f) // if input is lower than 0 turn to targetf { transform.rotation = Quaternion.Lerp(transform.rotation, targetf, Time.deltaTime * smooth); } if (Input.GetAxisRaw ("Vertical") > 0.0f) // if input is higher than 0 turn to targetb { transform.rotation = Quaternion.Lerp(transform.rotation, targetb, Time.deltaTime * smooth); } The Values (270 and 90) and Axis are because I had to turn my model itself in the very first place to face towards any of the movement directions.

• In agile environment, how is bug tracking and iteration tracking consolidated.

  - by DXM

  This topic stemmed from my other question about management-imposed waterfall-like schedule. From the responses in the other thread, I gathered this much about what is generally advised: Each story should be completed with no bugs. Story is not closed until all bugs have been addressed. No news there and I think we can all agree with this. If at a later date QA (or worse yet a customer) finds a bug, the report goes into a bug tracking database and also becomes a story which should be prioritized just like all other work. Does this sum up general handling of bugs in agile environment? If yes, the part I'm curious about is how do teams handle tracking in two different systems? (unless most teams don't have different systems). I've read a lot of advice (including Joel's blog) on software development in general and specifically on importance of a good bug tracking tool. At the same time when you read books on agile methodology, none of them seem to cover this topic because in "pure" agile, you finish iteration with no bugs. Feels like there's a hole there somewhere. So how do real teams operate? To track iterations you'd use (whiteboard, Rally...), to track bugs you'd use something from another set of products (if you are lucky enough, you might even get stuck with HP Quality Center). Should there be 2 separate systems? If they are separate, do teams spend time creating import/sync functionality between them? What have you done in your company? Is bug tracking software even used? Or do you just go straight to creating a story?

• "Siebel2FusionCRM Integration" solution by ec4u (D)

  - by Richard Lefebvre

  ec4u, a CRM System Integration leader based in Germany and Switzerland, and an historical Oracle/Siebel partner, offers a complete "Siebel2FusionCRM Integration" solution, based on tools methodology and services. ec4u Siebel2FusionCRM Integration solution's main objectives are: Integration between Siebel (on-premise) and Fusion CRM / Marketing (“in the cloud”) Accounts, Contacts and Addresses are maintained by Sales in Siebel CRM and synchronized in real-time into Fusion CRM / Marketing CDM Processing ensures clean data for marketing campaigns (validation and deduplication) Create E-Mail marketing campaigns and newsletters in Fusion The solution features: Upsert processes figure out what information needs to be updated, inserted or terminated (deleted). However, as Siebel is the data master, it is still a one-way synchronization. Handle deleted or nullified information by terminating them in Fusion CRM (set start and end date to define the validity period) Initial load and real-time synchronization use the same processes Invocations/Operations can be repeated due to no transactional support from Fusion web services Tagging sub entries in case of 1 to N mapping (Example: Telephone number is one simple field in Siebel but in Fusion you can have multiple telephone numbers in a sub table) E-Mail-Notification in case of any error (containing error message, instance number, detailed payload) Schematron Validation Interested? Looking for more details or a partnership with ec4u for a "Siebel2FusionCRM Integration" project? Contact: Gregor Bublitz, Director Expert Services ([email protected])

• Do we have enough time to build an electric car future?

  - by julien.groues

  A recent article from Greenbang has posed the question 'Do we have enough time to build an electric car future?'. The writer discusses that, although the future of transport might lie with electric cars, there is concern regarding whether we'll be able to build the market and infrastructure required to support them, before carbon and oil constraints create difficulties in powering the vehicles. Of course, the increasing use of Electric vehicles (EVs) is going to put excessive pressure on energy grids, as large volumes of electricity will need to be directed to charging points, which in turn must handle fluctuating demand at peak times. EVs are increasing in popularity as a sustainable method of transport to reduce carbon consumption, and electric utilities will have the opportunity, and the challenge, to quickly determine the best methods to fuel these vehicles and accommodate the associated increases in demand for energy. Critically, efficient software is required to provide diagnostic and predictive capabilities related to EV refuelling - for example, anticipated electricity flow will need to be addressed as the number of EVs on the road increases, and electricity will need to be directed to specific areas on-demand as vehicles attempt to recharge en-mass. But a smart grid infrastructure can meet these demands, intelligently. The implementation of a smart grid is not in the distant future, it is an achievable reality for utilities via simple installation of new software and technologies, which can be done incrementally for those facing existing legacy systems or concerned with upfront costs. The smart grid is integral to the monitoring and control of energy use as well as the future-proofing of the energy grid. A smart grid will be critical to meeting the electricity requirements of new EVs and will ensure their successful deployment by providing a reliable foundation for the data handling required to record and manage electricity distribution - from recording and assessing energy usage, to analysing data and sharing information with consumers via green billing. http://www.greenbang.com/do-we-have-enough-time-to-build-an-electric-car-future_14248.html
