• SQL SERVER – Get 2 of My Books FREE at Koenig Tech Day – Where Technologies Converge!

  - by pinaldave

  As a regular reader of my blog – you must be aware of that I love to write books and talk about various subjects of my book. The founders of Koenig Solutions are my very old friends, I know them for many years. They have been my biggest supporter of my books. Coming weekend they have a technology event at their Bangalore Location. Every attendee of the technology event will get a set of two books worth Rs. 450 – ‘SQL Server Interview Questions And Answers‘ and ‘SQL Wait Stats Joes 2 Pros‘. I am going to cover a couple of topics of the books and present  as well. I am very confident that every attendee will be having a great time. I will be covering following subjects: SQL Server Tricks and Tips for Blazing Fast Performance Slow Running Queries (SQL) are the most common problem that developers face while working with SQL Server. While it is easy to blame the SQL Server for unsatisfactory performance, however the issue often persists with the way queries have been written, and how SQL Server has been set up. The session will focus on the ways of identifying problems that slow down SQL Servers, and tricks to fix them. Developers will walk out with scripts and knowledge that can be applied to their servers, immediately post the session. After the session is over – I will point to what exact location in the book where you can continue for the further learning. I am pretty excited, this is more like book reading but in entire different format. The one day event will cover four technologies in four separate interactive sessions on: Microsoft SQL Server Security VMware/Virtualization ASP.NET MVC Date of the event: Dec 15, 2012 9 AM to 6PM. Location of the event:  Koenig Solutions Ltd. # 47, 4th Block, 100 feet Road, 3rd Floor, Opp to Shanthi Sagar, Koramangala, Bangalore- 560034 Mobile : 09008096122 Office : 080- 41127140 Organizers have informed me that there are very limited seats for this event and technical session based on my book will start at Sharp 9 AM. If you show up late there are chances that you will not get any seats. Registration for the event is a MUST. Please visit this link for further information.

• How and when to ask for a pay raise?

  - by Nico

  When should one ask for a pay raise? Will I know when the time is right for a pay raise? or should I just think "I deserve a pay raise for X and Y." When would be a moment to ask for a pay grade? For instance, if you are in a company that outsources to others, could it be the right moment to ask when they move you to a different physical workplace? Maybe a few weeks/months after you started working as a consultant at the client? Should you ask for one after engaging new technologies or something you've never worked with before? In short, should you ask for a raise for a "business motive" (they move you, they assign you new responsibilities), a "professional motive" (you are required to learn new languages or technologies), or a "personal motive" (you are having twins, your mother died and you need to arrange the funeral), or are all of the above potentially valid motives? How should one ask for it? Asking for a pay raise can be difficult for some people, how you deal with this? Do you just walk up to your manager and tell him "I need more money", "I think I deserve a pay raise"? Do you suggest you might have other offers on the table? Couldn't this be counterproductive if you actually really want to stay in the company you are in (because you like the environment, made a few friends, and like all the features they give you besides your pay grade; say: free sodas, parties, after-offices that happen pretty often, a ps3 you can grab when you are tired or want to chill out, courses, english classes, football games, etc, etc. [these would be my reasons not to leave]). I mean, how would you ask for a pay raise, effectively, but without pretending to threaten to leave the company if you don't get it? Because you don't actually want to. How would you deal with their answer? If they tell you they don't think you deserve a raise, would you ask for their reasons, would you get furious and trash the room? If they give you their reasons why they think you don't deserve a pay raise yet, would you discuss this with them or just take their opinion as factual? What if they ask you how much more you think you deserve to be being paid? Should you have thought this before-hand, or expect them to set the new grade? If they do agree to a pay raise, should you expect extra work to be thrown your way, or should everything remain the same, except your pay grade?

• Moving Character in C# XNA Not working

  - by Matthew Stenquist

  I'm having trouble trying to get my character to move for a game I'm making in my sparetime for the Xbox. However, I can't seem to figure out what I'm doing wrong , and I'm not even sure if I'm doing it right. I've tried googling tutorials on this but I haven't found any helpful ones. Mainly, ones on 3d rotation on the XNA creators club website. My question is : How can I get the character to walk towards the right in the MoveInput() function? What am I doing wrong? Did I code it wrong? The problem is : The player isn't moving. I think the MoveInput() class isn't working. Here's my code from my character class : using System; using System.Collections.Generic; using System.Linq; using System.Text; using Microsoft.Xna.Framework; using Microsoft.Xna.Framework.Graphics; using Microsoft.Xna.Framework.Input; namespace Jumping { class Character { Texture2D texture; Vector2 position; Vector2 velocity; int velocityXspeed = 2; bool jumping; public Character(Texture2D newTexture, Vector2 newPosition) { texture = newTexture; position = newPosition; jumping = true; } public void Update(GameTime gameTime) { JumpInput(); MoveInput(); } private void MoveInput() { //Move Character right GamePadState gamePad1 = GamePad.GetState(PlayerIndex.One); velocity.X = velocity.X + (velocityXspeed * gamePad1.ThumbSticks.Right.X); } private void JumpInput() { position += velocity; if (GamePad.GetState(PlayerIndex.One).Buttons.A == ButtonState.Pressed && jumping == false) { position.Y -= 1f; velocity.Y = -5f; jumping = true; } if (jumping == true) { float i = 1.6f; velocity.Y += 0.15f * i; } if (position.Y + texture.Height >= 1000) jumping = false; if (jumping == false) velocity.Y = 0f; } public void Draw(SpriteBatch spriteBatch) { spriteBatch.Draw(texture, position, Color.White); } } }

• SharePoint Designer 2010 Workflow Email Link To Item

  - by Brian Jackett

  In this post I’ll walk you through the process of sending an email that contains a link to the current item from a SharePoint Designer 2010 workflow.  This is a process that has been published on many other forums and blogs, but many that I have seen are more complex than seems necessary. Problem     A common request from SharePoint users is to get an email which contains a link to review/approve/edit the workflow item.  SharePoint list items contain an automatic property for Url Path, but unfortunately that Url is not properly formatted to retrieve the item if you include it directly on the message body.  I tried a few solutions suggested from other blogs or forums that took a substring of the Url Path property, concatenated the display form view Url, and mixed in some other strings.  While I was able to get this working in some scenarios I still had issues in general. Solution     My solution involved adding a hyperlink to the message body.  This ended up being far easier than I had expected and fairly intuitive once I found the correct property to use.  Follow these steps to see what I did.     First add a “Send an Email” action to your workflow.  Edit the action to pull up the email configuration dialog.  Click the “Add hyperlink” button seen below. When prompted for the address of the link click the fx button to perform a lookup.  Choose Workflow Context from the “data source” dropdown.  Choose Current Item URL from the “field from source” dropdown.  Click OK. Your Edit Hyperlink dialog should now look something like this. The end result will be a hyperlink added to your email pointing to the current workflow item.  Note: this link points to the non-modal dialog display form (display form similar to what you had in 2007). Conclusion     In this post I walked you through the steps to create a SharePoint Designer 2010 workflow with an email that contains a link to the current item.  While there are many other options for accomplishing this out on the web I found this to be a more concise process and easy to understand.  Hopefully you found this helpful as well.  Feel free to leave any comments or feedback if you’ve found other ways that were helpful to you.         -Frog Out

• KVM Virtual guest Paused on Reboot

  - by David Hamilton

  I'm running REHL 6 and just installed a Ubuntu Server Guest via KVM set to start at boot. This works correctly and the guest loads, but it loads "paused" and requires that I manually un-pause it. Can someone give me a hint as to how I can I get the Guest OS to actually become active on boot? Here is the libvert dump as requested...Also tried libvert auto-start --- no effect. <domain type='kvm' id='1'> <name>MailServer</name> <uuid>a61dae75-1f5c-d536-718f-3c615d9b4868</uuid> <memory>4194304</memory> <currentMemory>4194304</currentMemory> <vcpu>4</vcpu> <os> <type arch='x86_64' machine='rhel6.0.0'>hvm</type> <boot dev='hd'/> </os> <features> <acpi/> <apic/> <pae/> </features> <clock offset='utc'/> <on_poweroff>destroy</on_poweroff> <on_reboot>restart</on_reboot> <on_crash>restart</on_crash> <devices> <emulator>/usr/libexec/qemu-kvm</emulator> <disk type='file' device='disk'> <driver name='qemu' type='raw' cache='none'/> <source file='/home/MailServer/MailServer-1.img'/> <target dev='hda' bus='ide'/> <alias name='ide0-0-0'/> <address type='drive' controller='0' bus='0' unit='0'/> </disk> <disk type='block' device='cdrom'> <driver name='qemu' type='raw'/> <target dev='hdc' bus='ide'/> <readonly/> <alias name='ide0-1-0'/> <address type='drive' controller='0' bus='1' unit='0'/> </disk> <controller type='ide' index='0'> <alias name='ide0'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x01' function='0x1'/> </controller> <interface type='bridge'> <mac address='52:54:00:cd:f9:9f'/> <source bridge='br0'/> <target dev='vnet0'/> <model type='virtio'/> <alias name='net0'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/> </interface> <serial type='pty'> <source path='/dev/pts/1'/> <target port='0'/> <alias name='serial0'/> </serial> <console type='pty' tty='/dev/pts/1'> <source path='/dev/pts/1'/> <target port='0'/> <alias name='serial0'/> </console> <input type='mouse' bus='ps2'/> <graphics type='vnc' port='5900' autoport='yes'/> <sound model='ac97'> <alias name='sound0'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x04' function='0x0'/> </sound> <video> <model type='cirrus' vram='9216' heads='1'/> <alias name='video0'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x02' function='0x0'/> </video> <memballoon model='virtio'> <alias name='balloon0'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x05' function='0x0'/> </memballoon> </devices> <seclabel type='dynamic' model='selinux'> <label>system_u:system_r:svirt_t:s0:c211,c271</label> <imagelabel>system_u:object_r:svirt_image_t:s0:c211,c271</imagelabel> </seclabel></domain>

• The JDEdwards EnterpriseOne PreSales University

  - by Julien Haye

  Istanbul NOV 5-9 Wednesday, NOV 7 - It is raining outside and I am sitting in my hotel room (#106) in Istanbul and create my first blog entry. Today this blog was enabled and I am excited to have the ability to share my (first) thoughts with the EMEA JDE Partner Community. I am here in Istanbul because we are currently running the JDEdwards PreSales University Event series. This PreSales University is an established event series which we deliver the fifth time now and the first time in the ECEMEA region. Delegates value the openness and competence from the Product Strategy and Product Development Team from Denver and India. Together with the regional Oracle PreSales team we had very valuable discussions around product features and functions and about the business value of the new delivered applications and tools. Additionally the event provides endless opportunities to exchange ideas with other JD Edwards Partner and the Oracle PreSales Team. With its focus on sharing and learning, best practice, user experience and transforming technologies, delegates will leave this event with an abundance of new ideas and best practices to try for your coming projects and existing customer implementations. A day out of the office gives delegates a chance to gain a new perspective on their business processes. Everybody sees better ways of working just by being immersed in an environment where the focus is on using products more effectively. Apps Track: Highly concentrated participants in Istanbul listening to Jeff Erickson presenting the news about OneView Reporting. Jeff: We believe “The things you said”. The event is organized into two tracks, one for Apps and one for Tech. Everybody was able to learn new features and functions and how to position this products. The focus was on the new Apps release 9.1 and Tools Release 9.1.2 and their Value Propositions. For all topics hands-on exercises has been given to the participants. Even very experienced senior consultants did learn a lot from this event. In total we have 55 people registered and we still have some more content to deliver. By the way: Istanbul is a nice place to be. I already booked my next trip to this beautiful city. In two weeks we deliver the JD Edwards EECIS Executive Forum again in Istanbul. Once again a tough Agenda. I will let you know if I had the ability to have a walk outside and see a bit more of this beautiful city. At least I expect to have a different room number. Many greetings Hartmut WieseOracle Alliances & Channels EMEA

• Puppet: Getting Started On Windows

  - by Robz / Fervent Coder

  Originally posted on: http://geekswithblogs.net/robz/archive/2014/08/07/puppet-getting-started-on-windows.aspxNow that we’ve talked a little about Puppet. Let’s see how easy it is to get started. Install Puppet Let’s get Puppet Installed. There are two ways to do that: With Chocolatey: Open an administrative/elevated command shell and type: choco install puppet Download and install Puppet manually - http://puppetlabs.com/misc/download-options Run Puppet Let’s make pasting into a console window work with Control + V (like it should): choco install wincommandpaste If you have a cmd.exe command shell open, (and chocolatey installed) type: RefreshEnv The previous command will refresh your environment variables, ala Chocolatey v0.9.8.24+. If you were running PowerShell, there isn’t yet a refreshenv for you (one is coming though!). If you have to restart your CLI (command line interface) session or you installed Puppet manually open an administrative/elevated command shell and type: puppet resource user Output should look similar to a few of these: user { 'Administrator': ensure => 'present', comment => 'Built-in account for administering the computer/domain', groups => ['Administrators'], uid => 'S-1-5-21-some-numbers-yo-500', } Let's create a user: puppet apply -e "user {'bobbytables_123': ensure => present, groups => ['Users'], }" Relevant output should look like: Notice: /Stage[main]/Main/User[bobbytables_123]/ensure: created Run the 'puppet resource user' command again. Note the user we created is there! Let’s clean up after ourselves and remove that user we just created: puppet apply -e "user {'bobbytables_123': ensure => absent, }" Relevant output should look like: Notice: /Stage[main]/Main/User[bobbytables_123]/ensure: removed Run the 'puppet resource user' command one last time. Note we just removed a user! Conclusion You just did some configuration management /system administration. Welcome to the new world of awesome! Puppet is super easy to get started with. This is a taste so you can start seeing the power of automation and where you can go with it. We haven’t talked about resources, manifests (scripts), best practices and all of that yet. Next we are going to start to get into more extensive things with Puppet. Next time we’ll walk through getting a Vagrant environment up and running. That way we can do some crazier stuff and when we are done, we can just clean it up quickly.

• Windows Phone 7 + Azure.and a couple of nuggets

  I recently gave a talk about Windows Phone 7 at a Bizpark Camp in San Francisco.  The camp had two focuses: Azure and Windows Phone 7.  My presentation covered WP7 portion of the camp.  During my presentation I highlighted the phone platform and talked about some of the differentiators from design, technology and a business standpoint.    Whenever I watch presentations or go to tech meet-ups I feel like I get the most value when I can walk away with a few nuggets that I wouldnt necessarily have known about otherwise.  That said, I tried to add a few resources into my presentation that should be helpful when building WP7 apps.      Nuggets Seeing that the camp was focused on Azure and WP7 I decided to augment my presentation with a code sample.  The intention was to give some insight on how to approach building WP7 applications that talk to Azure.  Some colleges of mine here at Clarity have posted a sample on codeplex focused on getting up and running with WP7 and Azure..you can check it out HERE.   The project is not a hello world app, and is targeted at people who have some experience with the platform and a working knowledge of silverlight. Also, during my presentation I mentioned some limitations with the current phone sdk.  Our sample code on contains work-abounds for the following: #1 Panorama Control #2  Tilt effect #3   Animating Frame #4   Sample architecture (leveraging MVVM light)  and coding patterns.  Note: For the sample phone project we used an azure token that will expire in the next couple of months.  When that happensin the downloads section of the codeplex project there a link to a local development fabric that can be used for local development Presentation Admittedly, the slide deck is pretty design heavy, and doesnt contain much text.  This was semi-intentional to encourage people to come out to the camps and hear it first hand.  There is some additional info found the notes of the PPTX.  Dont forget to check out the full presentation at the Chicago Bizspark Camp on May 21st here at the Clarity Office.  Or on June 4th in  Los Angeles. You can DOWNLOAD the Slides here:  PPTX  |  PDF or view it inline below.  View more presentations from eklimcz. Cheers!

• Introducing Windows Azure Mobile Services

  - by Clint Edmonson

  Today I’m excited to share that the Windows Azure Mobile Services public preview is now available. This preview provides a turnkey backend cloud solution designed to accelerate connected client app development. These services streamline the development process by enabling you to leverage the cloud for common mobile application scenarios such as structured storage, user authentication and push notifications. If you’re building a Windows 8 app and want a fast and easy path to creating backend cloud services, this preview provides the capabilities you need. You to take advantage of the cloud to build and deploy modern apps for Windows 8 devices in anticipation of general availability on October 26th. Subsequent preview releases will extend support to iOS, Android, and Windows Phone. Features The preview makes it fast and easy to create cloud services for Windows 8 applications within minutes. Here are the key benefits:  Rapid development: configure a straightforward and secure backend in less than five minutes. Create modern mobile apps: common Windows Azure plus Windows 8 scenarios that Windows Azure Mobile Services preview will support include:  Automated Service API generation providing CRUD functionality and dynamic schematization on top of Structured Storage Structured Storage with powerful query support so a Windows 8 app can seamlessly connect to a Windows Azure SQL database Integrated Authentication so developers can configure user authentication via Windows Live Push Notifications to bring your Windows 8 apps to life with up to date and relevant information Access structured data: connect to a Windows Azure SQL database for simple data management and dynamically created tables. Easy to set and manage permissions. Pricing One of the key things that we’ve consistently heard from developers about using Windows Azure with mobile applications is the need for a low cost and simple offer.

• Issue 56 - Super Stylesheets Skinning in DotNetNuke 5

  May 2010 Welcome to Issue 56 of DNN Creative Magazine In this issue we show you how to use the powerful new Super Stylesheets skinning feature in DotNetNuke 5. Super Stylesheets are ideal for both beginner and experienced skin designers, they provide skin layouts using CSS. The advantage of Super Stylesheets is that you can easily create a skin layout which works in all browsers without the need to learn complex CSS techniques. They are also very quick to build and you can change a skin layout in a matter of minutes rather than hours. We show you how to build a skin from the very beginning using Super Stylesheets, we show you how to create various skin layouts, as well as multi-layouts. We also show you how to style the skin, how to add tokens such as the logo, menu, login links etc. and walk you through how to create a fully working skin from scratch. Following this we continue the Open Web Studio tutorials, this month we demonstrate how to create an installable DotNetNuke PA module using OWS. This is an essential technique which allows you to package up the OWS applications that you have created and build them into an installable zip package. The zip file is then installable as a standard DotNetNuke module which means you can easily install your OWS applications on other DotNetNuke installations by simply installing them as a standard DotNetNuke module. To finish, we have part six of the "How to Build a News Application with DotNetMushroom Rapid Application Developer (RAD)" article, where we demonstrate how to create a News Carousel using RAD, JQuery and the JCarousel plugin. This issue comes complete with 15 videos.

• efficient collision detection - tile based html5/javascript game

  - by Tom Burman

  Im building a basic rpg game and onto collisions/pickups etc now. Its tile based and im using html5 and javascript. i use a 2d array to create my tilemap. Im currently using a switch statement for whatever key has been pressed to move the player, inside the switch statement. I have if statements to stop the player going off the edge of the map and viewport and also if they player is about to land on a tile with tileID 3 then the player stops. Here is the statement: canvas.addEventListener('keydown', function(e) { console.log(e); var key = null; switch (e.which) { case 37: // Left if (playerX > 0) { playerX--; } if(board[playerX][playerY] == 3){ playerX++; } break; case 38: // Up if (playerY > 0) playerY--; if(board[playerX][playerY] == 3){ playerY++; } break; case 39: // Right if (playerX < worldWidth) { playerX++; } if(board[playerX][playerY] == 3){ playerX--; } break; case 40: // Down if (playerY < worldHeight) playerY++; if(board[playerX][playerY] == 3){ playerY--; } break; } viewX = playerX - Math.floor(0.5 * viewWidth); if (viewX < 0) viewX = 0; if (viewX+viewWidth > worldWidth) viewX = worldWidth - viewWidth; viewY = playerY - Math.floor(0.5 * viewHeight); if (viewY < 0) viewY = 0; if (viewY+viewHeight > worldHeight) viewY = worldHeight - viewHeight; }, false); My question is, is there a more efficient way of handling collisions, then loads of if statements for each key? The reason i ask is because i plan on having many items that the player will need to be able to pickup or not walk through like walls cliffs etc. Thanks for your time and help Tom

• Iterative and Incremental Principle Series 2: Finding Focus

  - by llowitz

  Welcome back to the second blog in a five part series where I recount my personal experience with applying the Iterative and Incremental principle to my daily life.  As you recall from part one of the series, a conversation with my son prompted me to think about practical applications of the Iterative and Incremental approach and I realized I had incorporated this principle in my exercise regime.    I have been a runner since college but about a year ago, I sustained an injury that prevented me from exercising.  When I was sufficiently healed, I decided to pick it up again.  Knowing it was unrealistic to pick up where I left off, I set a goal of running 3 miles or approximately for 30 minutes.    I was excited to get back into running and determined to meet my goal.  Unfortunately, after what felt like a lifetime, I looked at my watch and realized that I had 27 agonizing minutes to go!  My determination waned and my positive “I can do it” attitude was overridden by thoughts of “This is impossible”.   My initial focus and excitement was not sustained so I never met my goal.   Understanding that the 30 minute run was simply too much for me mentally, I changed my approach.   I decided to try interval training.  For each interval, I planned to walk for 3 minutes, then jog for 2 minutes, and finally sprint for 1 minute, and I planned to repeat this pattern 5 times.  I found that each interval set was challenging, yet achievable, leaving me excited and invigorated for my next interval.  I easily completed five intervals – or 30 minutes!!  My sense of accomplishment soared. What does this have to do with OUM?  Have you heard the saying -- “How do you eat an elephant?  One bite at a time!”?  This adage certainly applies in my example and in an OUM systems implementation.  It is easier to manage, track progress and maintain team focus for weeks at a time, rather than for months at a time.   With shorter milestones, the project team focuses on the iteration goal.  Once the iteration goal is met, a sense of accomplishment is experience and the team can be re-focused on a fresh, yet achievable new challenge.  Join me tomorrow as I expand the concept of Iterative and incremental by taking a step back to explore the recommended approach for planning your iterations.

• How do I maintain a really poorly written code base?

  - by onlineapplab.com

  Recently I got hired to work on existing web application because of NDA I'm not at liberty to disclose any details but this application is working online in sort of a beta testing stage before official launch. We have a few hundred users right now but this number is supposed to significantly increase after official launch. The application is written in PHP (but it is irrelevant to my question) and is running on a dual xeon processor standalone server with severe performance problems. I have seen a lot of bad PHP code but this really sets new standards, especially knowing how much time and money was invested in developing it. it is as badly coded as possible there is PHP, HTML, SQL mixed together and code is repeated whenever it is necessary (especially SQL queries). there are not any functions used, not mentioning any OOP there are four versions of the app (desktop, iPhone, Android + other mobile) each version has pretty much the same functionality but was created by copying the whole code base, so now there are some differences between each version and it is really hard to maintain the database is really badly designed, which is causing severe performance problems also for fixing some errors in PHP code there is a lot of database triggers used which are updating data on SELECT and on INSERT so any testing is a nightmare Basically, any sin of a bad programming you can imagine is there for example it is not only possible to use SQL injections in literally every place but you can log into app if you use a login which doesn't exist and an empty password. The team which created this app is not working on it any more and there is an outsourced team which suggested that there are some problems but was never willing to deal with the elephant in the room partially because they've got a very comfortable contract and partially due to lack of skills (just my opinion). My job was supposed to be fixing some performance problems and extending existing functionality but first thing I was asked to do was a review of the existing code base. I've made my review and it was quite a shock for the management but my conclusions were after some time finally confirmed by other programmers. Management made it clear that it is not possible to start rewriting this app from scratch (which in my opinion should be done). We have to maintain its operable state and at the same time fix performance errors and extend the functionality. My question is, as I don't want just to patch the existing code, how to transform this into properly written app while keeping the existing code working at the same time? My plan is: Unify four existing versions into common code base (fixing only most obvious errors). Redesign db and use triggers to populate it with data (so data will be maintained in two formats at the same time) All new functionality will be written as separate project. Step by step transfer existing functionality into the new project After some time everything will be in the new project Some explanation about #2, right now it is practically impossible to make any updates in existing db any change requires reviewing whole code and making changes in many places. Is such plan feasible at all? Another solution is to walk away and leave the headache to someone else.

• My First 5K, the recap.

  - by Chris Williams

  It was a nice day to be outside (and trust me, those aren't words you'll hear from me often.) I got to the site around 7:45, hit the pre-reg table and got my number along with a goody bag full of coupons for racing gear, a water bottle and a tshirt. Oh and a map. Stashed all that stuff in the jeep, emptied my pockets of everything but my iPhone and my jeep key, and proceeded to walk around for a bit as people started showing up and signing in. It was fairly breezy, and there was definitely a storm coming... but it was anyone's guess on when it would actually arrive. It was interesting to see everyone who was participating. If I had to guess, I would say the event was 60-70% women, with a pretty broad distribution of age... as young as 13 to well over 60 (in both genders.) I don't know exactly how many folks were there, but it was well over 300. Eventually it was time to kick things off, and everyone made their way to the start line. All of the 5k and 10k runners were mixed together, starting at the same time. All the walkers and the people with strollers or dogs were in the back. It was pretty chaotic at first, once things started, but it thinned out fairly quickly. The 10k people and the hardcore runners sped ahead of everyone else and the walkers gradually lagged behind. The 5K course was pretty nice, winding around a lake down in Eden Prairie. The 10K course overlapped most of ours, but branched off a couple times too. I didn't run the whole time, but I started the race running and I ended it running, and did a mix of walking and running along the way. I met my goals, which were a) don't ever stop and b) don't be last. The weather managed to hold out for the entire race. It never got too hot, there was a nice breeze and it was mostly overcast. Pretty much perfect in my book. About 20-30 minutes after I left, the rain came down pretty hard. I had a good time, and will most likely do more of them. We'll see.

• How to keep a data structure synchronized over a network?

  - by David Gouveia

  Context In the game I'm working on (a sort of a point and click graphic adventure), pretty much everything that happens in the game world is controlled by an action manager that is structured a bit like: So for instance if the result of examining an object should make the character say hello, walk a bit and then sit down, I simply spawn the following code: var actionGroup = actionManager.CreateGroup(); actionGroup.Add(new TalkAction("Guybrush", "Hello there!"); actionGroup.Add(new WalkAction("Guybrush", new Vector2(300, 300)); actionGroup.Add(new SetAnimationAction("Guybrush", "Sit")); This creates a new action group (an entire line in the image above) and adds it to the manager. All of the groups are executed in parallel, but actions within each group are chained together so that the second one only starts after the first one finishes. When the last action in a group finishes, the group is destroyed. Problem Now I need to replicate this information across a network, so that in a multiplayer session, all players see the same thing. Serializing the individual actions is not the problem. But I'm an absolute beginner when it comes to networking and I have a few questions. I think for the sake of simplicity in this discussion we can abstract the action manager component to being simply: var actionManager = new List<List<string>>(); How should I proceed to keep the contents of the above data structure syncronized between all players? Besides the core question, I'm also having a few other concerns related to it (i.e. all possible implications of the same problem above): If I use a server/client architecture (with one of the players acting as both a server and a client), and one of the clients has spawned a group of actions, should he add them directly to the manager, or only send a request to the server, which in turn will order every client to add that group? What about packet losses and the like? The game is deterministic, but I'm thinking that any discrepancy in the sequence of actions executed in a client could lead to inconsistent states of the world. How do I safeguard against that sort of problem? What if I add too many actions at once, won't that cause problems for the connection? Any way to alleviate that?

• Oracle BPM and Open Data integration development

  - by drrwebber

  Rapidly developing Oracle BPM application solutions with data source integration previously required significant Java and JDeveloper skills. Now using open source tools for open data development significantly reduces the coding needed.  Key tasks can be performed with visual drag and drop designing combined with menu selections entry and automatic form generation directly from XSD schema definitions. The architecture used is extremely lightweight, portable, open platform and scalable allowing integration with a variety of Oracle and non-Oracle data sources and systems. Two videos available on YouTube walk through the process at both an introductory conceptual level and then a deep dive into the programming needed using JDeveloper, Oracle BPM composer and Oracle WLS (WebLogic Server) along with the CAM editor and Open-XDX open source tools. Also available are coding samples and resources from the GitHub project page, along with working online demonstration resources on the VerifyXML site. Combining Oracle BPM with these open source tools provides a comprehensive simple and elegant solution set. Development times are slashed and rapid prototyping is enabled. Also existing data sources can be integrated using open data formats with either XML or JSON along with CRUD accessing via the Open-XDX Java component. The Open-XDX tool is a code-free approach where data mapping is configured as templates using visual drag and drop in the CAM Editor open source tool.  XML or JSON is then automatically generated or processed (output or input) and appropriate SQL statements created to support the data accessing.   Also included is the ability to integrate with fillable PDF forms via the XML templates and the Java PDF form filling library.  Again minimal Java coding is needed to associate the XML source content with the PDF named fields.  The Oracle BPM forms can be automatically generated from XSD schema definitions that are built from the data mapping templates.  This dramatically simplifies development work as all the integration artifacts needed are created by the open source editor toolset. The developer level video is designed as a tutorial with segments, hands-on demonstrations and reviews.  This allows developers to learn the techniques and approaches used in incremental steps. The intended audience ranges from data analysts to developers and assumes only entry level Java skills and knowledge.  Most actions are menu driven while Java coding is limited to simply configuring values and parameters along with performing builds and deployments from JDeveloper and Oracle WLS.   Additional existing Oracle online training resources can be referenced on Oracle BPM and WLS that cover other normal delivery aspects such as user management and application deployment.

• OpenVPN - client-to-client traffic working in one direction but not the other

  - by Pawz

  I have the following VPN configuration: +------------+ +------------+ +------------+ | outpost |----------------| kino |----------------| guchuko | +------------+ +------------+ +------------+ OS: FreeBSD 6.2 OS: Gentoo 2.6.32 OS: Gentoo 2.6.33.3 Keyname: client3 Keyname: server Keyname: client1 eth0: 10.0.1.254 eth0: 203.x.x.x eth0: 192.168.0.6 tun0: 192.168.150.18 tun0: 192.168.150.1 tun0: 192.168.150.10 P-t-P: 192.166.150.17 P-t-P: 192.168.150.2 P-t-P: 192.168.150.9 Kino is the server and has client-to-client enabled. I am using "fragment 1400" and "mssfix" on all three machines. An mtu-test on both connections is successful. All three machines have ip forwarding enabled, by this on the gentoo boxes: net.ipv4.conf.all.forwarding = 1 And this on the FreeBSD box: net.inet.ip.forwarding: 1 In the server's "ccd" directory is the following files: client1: iroute 192.168.0.0 255.255.255.0 client3: iroute 10.0.1.0 255.255.255.0 The server config has these routes configured: push "route 192.168.0.0 255.255.255.0" push "route 10.0.1.0 255.255.255.0" route 192.168.0.0 255.255.255.0 route 10.0.1.0 255.255.255.0 Kino's routing table looks like this: 192.168.150.0 192.168.150.2 255.255.255.0 UG 0 0 0 tun0 10.0.1.0 192.168.150.2 255.255.255.0 UG 0 0 0 tun0 192.168.0.0 192.168.150.2 255.255.255.0 UG 0 0 0 tun0 192.168.150.2 0.0.0.0 255.255.255.255 UH 0 0 0 tun0 Outpost's like this: 192.168.150 192.168.150.17 UGS 0 17 tun0 192.168.0 192.168.150.17 UGS 0 2 tun0 192.168.150.17 192.168.150.18 UH 3 0 tun0 And Guchuko's like this: 192.168.150.0 192.168.150.9 255.255.255.0 UG 0 0 0 tun0 10.0.1.0 192.168.150.9 255.255.255.0 UG 0 0 0 tun0 192.168.150.9 0.0.0.0 255.255.255.255 UH 0 0 0 tun0 Now, the tests. Pings from Guchuko to Outpost's LAN IP work OK, as does the reverse - pings from Outpost to Guchuko's LAN IP. However... Pings from Outpost, to a machine on Guchuko's LAN work fine: .(( root@outpost )). (( 06:39 PM )) :: ~ :: # ping 192.168.0.3 PING 192.168.0.3 (192.168.0.3): 56 data bytes 64 bytes from 192.168.0.3: icmp_seq=0 ttl=63 time=462.641 ms 64 bytes from 192.168.0.3: icmp_seq=1 ttl=63 time=557.909 ms But a ping from Guchuko, to a machine on Outpost's LAN does not: .(( root@guchuko )). (( 06:43 PM )) :: ~ :: # ping 10.0.1.253 PING 10.0.1.253 (10.0.1.253) 56(84) bytes of data. --- 10.0.1.253 ping statistics --- 3 packets transmitted, 0 received, 100% packet loss, time 2000ms Guchuko's tcpdump of tun0 shows: 18:46:27.716931 IP 192.168.150.10 > 10.0.1.253: ICMP echo request, id 63009, seq 1, length 64 18:46:28.716715 IP 192.168.150.10 > 10.0.1.253: ICMP echo request, id 63009, seq 2, length 64 18:46:29.716714 IP 192.168.150.10 > 10.0.1.253: ICMP echo request, id 63009, seq 3, length 64 Outpost's tcpdump on tun0 shows: 18:44:00.333341 IP 192.168.150.10 > 10.0.1.253: ICMP echo request, id 63009, seq 3, length 64 18:44:01.334073 IP 192.168.150.10 > 10.0.1.253: ICMP echo request, id 63009, seq 4, length 64 18:44:02.331849 IP 192.168.150.10 > 10.0.1.253: ICMP echo request, id 63009, seq 5, length 64 So Outpost is receiving the ICMP request destined for the machine on it's subnet, but appears not be forwarding it. Outpost has gateway_enable="YES" in its rc.conf which correctly sets net.inet.ip.forwarding to 1 as mentioned earlier. As far as I know, that's all that's required to make a FreeBSD box forward packets between interfaces. Is there something else I could be forgetting ? FWIW, pinging 10.0.1.253 from Kino has the same result - the traffic does not get forwarded. UPDATE: I've found that I can only ping certain IP's on Guchuko's LAN from Outpost. From Outpost I can ping 192.168.0.3 and 192.168.0.2, but 192.168.99 and 192.168.0.4 are unreachable. The same tcpdump behavior can be seen. I think this means the problem can't be due to ipforwarding or routing, because Outpost can reach SOME hosts on Guchuko's LAN but not others and likewise, Guchuko can reach two hosts on Outpost's LAN, but not others. This baffles me.

• Innovation for Retailers

  - by David Dorf

  One of my main objectives for this blog is to point out emerging technologies and how they might apply to the retail industry.  But ideas are just the beginning; retailers either have to rely on vendors or have their own lab to explore these ideas and see which ones work.  (A healthy dose of both is probably the best solution.)  The Nordstrom Innovation Lab is a fine example of dedicating resources to cultivate ideas and test prototypes. The video below, from 2011, is a case study in which the team builds an iPad app that helps customers purchase sunglasses in the store.  Customers take pictures of themselves wearing different sunglasses, then can do side-by-side comparisons. There are a few interesting take-aways from their process.  First, they are working in the store alongside employees and customers.  There's no concept of documenting all the requirements then building the product.  Instead, they work closely with those that will be using the app in order to fully understand what's needed.  When they find an issue, they change the software onsite and try again.  This iterative prototyping ensures their product hits the mark.  Feels like Extreme Programming if you recall that movement. Second, they have time-boxed the project to one week.  Either it works or it doesn't, and either way they've only expended a week's worth of resources.  Innovation always entails failure, and those that succeed are often good at detecting failure quickly then adjusting.  Fail fast and fail often. Third, its not always about technology.  I was impressed they used paper designs to walk through user stories and help understand the needs of the customer.  Pen and paper is the innovator's most powerful tool. Our Retail Applied Research (RAR) team uses some of these concepts in our development process.  (Calling it a process is probably overkill.)  We try to give life to concepts quickly so the rest of organization can help us decide if we're heading the right direction.  It takes many failures before finding a successful product.

• TransportWithMessageCredential & Service Bus – Introduction

  - by Michael Stephenson

  Recently we have been working on a project using the Windows Azure Service Bus to expose line of business applications. One of the topics we discussed a lot was around the security aspects of the solution. Most of the samples you see for Windows Azure Service Bus often use the shared secret with the Access Control Service to protect the service bus endpoint but one of the problems we found was that with this scenario any claims resulting from credentials supplied by the client are not passed through to the service listening to the service bus endpoint. As an example of this we originally were hoping that we could give two different clients their own shared secret key and the issuer for each would indicate which client it was. If the claims had flown to the listening service then we could check that the message sent by client one was a type they are allowed to send. Unfortunately this claim isn't flown to the listening service so we were unable to implement this scenario. We had also seen samples that talk about changing the relayClientAuthenticationType attribute would allow you to authenticate the client within the service itself rather than with ACS. While this was interesting it wasn't exactly what we wanted. By removing the step where access to the Relay endpoint is protected by authentication against ACS it means that anyone could send messages via the service bus to the on-premise listening service which would then authenticate clients. In our scenario we certainly didn't want to allow clients to skip the ACS authentication step because this could open up two attack opportunities for an attacker. The first of these would allow an attacker to send messages through to our on-premise servers and potentially cause a denial of service situation. The second case would be with the same kind of attack by running lots of messages through service bus which were then rejected the attacker would be causing us to incur charges per message on our Windows Azure account. The correct way to implement our desired scenario is to combine one of the common options for authenticating against ACS so the service bus endpoint cannot be accessed by an unauthenticated caller with the normal WCF security features using the TransportWithMessageCredential security option. Looking around I could not find any guidance on how to implement this correctly so on the back of setting this up I decided to write a couple of articles to walk through a couple of the common scenarios you may be interested in. These are available on the following links: Walkthrough - Combining shared secret and username token Walkthrough – Combining shared secret and certificates

• Multiplayer tile based movement synchronization

  - by Mars

  I have to synchronize the movement of multiple players over the Internet, and I'm trying to figure out the safest way to do that. The game is tile based, you can only move in 4 directions, and every move moves the sprite 32px (over time of course). Now, if I would simply send this move action to the server, which would broadcast it to all players, while the walk key is kept being pressed down, to keep walking, I have to take this next command, send it to the server, and to all clients, in time, or the movement won't be smooth anymore. I saw this in other games, and it can get ugly pretty quick, even without lag. So I'm wondering if this is even a viable option. This seems like a very good method for single player though, since it's easy, straight forward (, just take the next movement action in time and add it to a list), and you can easily add mouse movement (clicking on some tile), to add a path to a queue, that's walked along. The other thing that came to my mind was sending the information that someone started moving in some direction, and again once he stopped or changed the direction, together with the position, so that the sprite will appear at the correct position, or rather so that the position can be fixed if it's wrong. This should (hopefully) only make problems if someone really is lagging, in which case it's to be expected. For this to work out I'd need some kind of queue though, where incoming direction changes and stuff are saved, so the sprite knows where to go, after the current movement to the next tile is finished. This could actually work, but kinda sounds overcomplicated. Although it might be the only way to do this, without risk of stuttering. If a stop or direction change is received on the client side it's saved in a queue and the char keeps moving to the specified coordinates, before stopping or changing direction. If the new command comes in too late there'll be stuttering as well of course... I'm having a hard time deciding for a method, and I couldn't really find any examples for this yet. My main problem is keeping the tile movement smooth, which is why other topics regarding synchronization of pixel based movement aren't helping too much. What is the "standard" way to do this?
