  • Value cannot be null in sportstore exampe

    - by Naim
    Hi everyone, I am having this problem when I want to implement IoC for sportstore example. The code public WindsorControllerFactory(){ container = new WindsorContainer( new XmlInterpreter(new ConfigResource("castle")) ); var controllerTypes= from t in Assembly.GetExecutingAssembly().GetTypes() where typeof(IController).IsAssignableFrom(t) select t; foreach (Type t in controllerTypes) container.AddComponentLifeStyle(t.FullName, t, LifestyleType.Transient); } protected override IController GetControllerInstance(Type controllerType) { return (IController)container.Resolve(controllerType); } } The error said that the value cannot be null in the GetControllerInstance Any help will be appreciated ! Thanks! Naim

  • Returning std::vector by value

    - by deft_code
    It is oft said that in C++11 it is sane to return std::vector by value. In C++03 this was mostly true as RVO should optimize away the copy. But that should scared most developers away. In C++11 will a returned std::vector local variable always be moved? What if that vector is a member of a local variable instead of a local variable itself? Obviously returning a global variable will not be moved. What other cases will it not be moved?

  • GLSL - one-pass gaussian blur

    - by martin pilch
    It is possible to implement fragment shader to do one-pass gaussian blur? I have found lot of implementation of two-pass blur (gaussian and box blur): http://callumhay.blogspot.com/2010/09/gaussian-blur-shader-glsl.html http://www.gamerendering.com/2008/10/11/gaussian-blur-filter-shader/ http://www.geeks3d.com/20100909/shader-library-gaussian-blur-post-processing-filter-in-glsl/ and so on. I have been thinking of implementing gaussian blur as convolution (in fact, it is the convolution, the examples above are just aproximations): http://en.wikipedia.org/wiki/Gaussian_blur

  • Multi Pass Blend

    - by Kirk Patrick
    I am seeking the simplest working example of a two pass HLSL pixel shader. It can do anything really, but the main idea is to perform "ping ponging" to take the output of the first pass and then send it for the second pass. In my example I want to draw to the R channel and then draw to the G channel and produce a simple Venn Diagram in the shader, but need to detect overlap. I can currently detect one or the other but not overlap. There are a red and green circle overlapping, and I want to put a dynamic texture map in the overlap region. I can currently put it in either or. Below is how it looks in the shader. -------------------------------- Texture2D shaderTexture; SamplerState SampleType; ////////////// // TYPEDEFS // ////////////// struct PixelInputType { float4 position : SV_POSITION; float2 tex0 : TEXCOORD0; float2 tex1 : TEXCOORD1; float4 color : COLOR; }; //////////////////////////////////////////////////////////////////////////////// // Pixel Shader //////////////////////////////////////////////////////////////////////////////// float4 main(PixelInputType input) : SV_TARGET { float4 textureColor0; float4 textureColor1; // Sample the pixel color from the texture using the sampler at this texture coordinate location. textureColor0 = shaderTexture.Sample(SampleType, input.tex0); textureColor1 = shaderTexture.Sample(SampleType, input.tex1); if (input.color[0]==1.0f && input.color[1]==1.0f) // Requires multi-pass textureColor0 = textureColor1; return textureColor0; } Here is the calling code (that needs to be modified) m_d3dContext->IASetVertexBuffers(0, 2, vbs, strides, offsets); m_d3dContext->IASetIndexBuffer(m_indexBuffer.Get(), DXGI_FORMAT_R32_UINT,0); m_d3dContext->IASetPrimitiveTopology(D3D11_PRIMITIVE_TOPOLOGY_TRIANGLELIST); m_d3dContext->IASetInputLayout(m_inputLayout.Get()); m_d3dContext->VSSetShader(m_vertexShader.Get(), nullptr, 0); m_d3dContext->VSSetConstantBuffers(0, 1, m_constantBuffer.GetAddressOf()); m_d3dContext->PSSetShader(m_pixelShader.Get(), nullptr, 0); m_d3dContext->PSSetShaderResources(0, 1, m_SRV.GetAddressOf()); m_d3dContext->PSSetSamplers(0, 1, m_QuadsTexSamplerState.GetAddressOf());

  • PASS Summit edition of SolidQ Journal (November edition)

    - by Greg Low
    I've been travelling a lot again lately and while I was in Beijing, our SolidQ Journal team released the November edition, so I'm a bit late letting you know about it. In addition to the regular columnists, the November edition brought articles from some of our mentors that were presenting at the PASS summit. In the BI area this month, we have a feature from Davide Mauri that covers a new dimension loading tool (DLPC) which is available for free download to SolidQ Journal readers and PASS attendees....(read more)

  • PASS Summit Location follow up - result analysis

    - by simonsabin
    I've had a chance to look at the results directly and it is clear that there is a tough choice. On the one hand people are saying that they prefer to have PASS put their money into chapters and things like 24hrs of PASS rather than an event on the east coast. Whilst at the same time almost 50% more people said they would be more likely to attend an East Coast event than a Seattle event, and 60% more said they would be more likley to attend a US Central region event. Whats more 60% said that the summit should be outside of Seattle every other year with only 19% saying it should always stay in Seattle. So clearly there is a huge desire for a non Seattle event. Looking at the other reasons for keeping in Seattle and the big one being that people want Microsoft speakers. More people think its somewhat important of very important that the conference is in walking distance of the hotels and restaurants. Essentially the Q6 questions show an even balance for normal conference, highlighting that they are prepared to travel, not with the family and they want a well laid out conference. Whats very annoying is that the questions, as people have commented, were biased towards certain answers. For instance there was no option about whether people feel its important to have industry leading speakers, MVPs etc at the conference. Only questions about Microsoft speakers. I know survey writing is very difficult to avoid biasing the answers one way or another. There was also no choice to show peoples preference, would people prefer Microsoft speakers or the summit to be held on the East Coast/Central US. I also find it amazing that people prefer hundres of developers rather than the SQLCAT and CSS teams, surely that indicates another issue about a lack of understanding of what the these teams do. All in all it is clear that people showed they want an event outside of Seattle and don't want PASS to be putting money into that instead of into other community activites. I find it suprising that there appears to have been a huge weighting against certain questions which have prioritised them over the huge desire for a PASS summit outside of Seattle. Lets see where we will be in 2013 or maybe they will rethink 2012 who knows.

  • PASS: SQLRally Thoughts

    - by Bill Graziano
    The PASS Board recently decided that we wouldn’t put another US-based SQLRally on the calendar until we had a chance to review the program. I wanted to provide some of my thinking around this. Keep in mind that this is the opinion of one Board member. The Board committed to complete two SQLRally events to determine if an event modeled between SQL Saturday and the Summit was viable. We’ve completed the two events and now it’s time to step back and review the program. This is my seventh year on the PASS Board. Over that time people have asked me why PASS does certain things. Many, many times my answer has been “Because that’s the way we did it last year”. And I am tired of giving that answer. We need to take a step back and review the US-based SQLRally before we schedule another one. It would be irresponsible for me as a Board member to commit resources to this without validating that what we’re doing makes sense for the organization and our members. I have no doubt that this was a great event for the attendees. We just need to validate it’s the best use of our resources. Please keep in mind that we haven’t cancelled the event. We’ve just said we need to review it before scheduling another one. My opinion is that some fairly serious changes are needed to the model before we consider it again – IF we do it again. I’ve come to that conclusion after speaking with the Dallas organizers, our HQ team, our Marketing team, other Board members (including one of the Orlando organizers), attendees in Orlando and Dallas and visiting other similar events. I should point out that their views aren’t unanimous on nearly any part of this event -- which is one of the reasons I want to take some time and think about this before continuing. I think it’s helpful to look at the original goals of what we were trying to accomplish. Andy Warren wrote these up in August of 2010. My summary of these goals and some thoughts on each one is below. Many of these thoughts revolve around the growth of SQL Saturdays. In the two years since that document was written these events have grown significantly. The largest SQL Saturdays are now over 500 people which mean they are nearly the same size as our recent SQLRally. Our goals included: Geographic diversity. We wanted an event in an area of the country that was away from any given Summit location. I think that’s still a valid goal. But we also have SQL Saturdays all over the country. What does SQLRally bring to this that SQLSaturday doesn’t? Speaker growth. One of the stated goals was to build a “farm club” for speakers. This gives us a way for speakers to work up to speaking at Summit by speaking in front of larger crowds. What does SQLRally bring to this that the larger SQL Saturdays aren’t providing? Pre-Conference speakers is one obvious answer here. Lower price. On a per-day basis, SQLRally is roughly 1/4th the price of the Summit. We wanted a way for people to experience something Summit-like at a lower price point. The challenge is that we are very budget constrained at that lower price point. International Event Model.  (I need to write more about this but I’m out of time.  I’ll cover it in the next installment.) There are a number of things I really like about SQLRally. I love the smaller conferences. They give me a chance to meet more people than at something the size of Summit. I like the two day format. That gives you two evenings to be at social events with people. Seeing someone a second day is a great way to build a bond with that person. That’s more difficult to do at a SQL Saturday. We also need to talk about the financial aspects of the event. Last year generated a small $17,000 profit on revenues of $200,000. Percentage-wise that’s reasonable but on an absolute basis it’s not a huge amount in our budget. We think this year will lose between $30,000 and $50,000 and take roughly 1,000 hours of HQ time. We don’t have detailed financials back yet but that’s our best guess at this point. Part of that was driven by using a convention center instead of a hotel. Until we get detailed financials back we won’t have the full picture around the financial impact. This event also takes time and mindshare from our Marketing team. This may sound like a small thing but please don’t underestimate it. Our original vision for this was something that would take very little time from our Marketing team and just a few mentions in the Connector. It turned out to need more than that. And all those mentions and emails take up space we could use to talk about other events and other programs. Last I wanted to talk about some of the things I’m thinking about. I don’t think it’s as simple as saying if we just fix “X” it all gets better. Is this that much better of an event than SQL Saturdays? What if we gave a few SQL Saturdays some extra resources? When SQL Saturdays were around 250 people that wasn’t as viable. With some of those events over 500 we need to reconsider this. We need to get back to a hotel venue. That will help with cost and networking. Is this the best use of the 1,000 HQ hours that we invested in the event? Is our price-point correct? I’m leaning toward raising our price closer to Summit on a per-day basis. I think this will let us put on a higher quality event and alleviate much of the budget pressure. Should growing speakers be a focus? Having top-line pre-conference speakers helps market the event. It will also have an impact on pricing and overall profit. We should also ask if it actually does grow speakers. How many of these people will eventually register for Summit? Attend chapters? Is SQLRally a driver into PASS or is it something that chapters, etc. drive people to? Should we have one paid day and one free instead of two paid days? This is a very interesting model that is used by SQLBits in the UK. This gives you the two day aspect as well as offering options for paid and free attendees. I’m very intrigued by this. Should we focus on a topic? Buried in the minutes is a discussion of whether PASS should have a Business Analytics conference separate from Summit. This is an interesting question to consider. Would making SQLRally be focused on a particular topic make it more attractive? Would that even be a SQLRally? Can PASS effectively manage the two events? (FYI - Probably not.) Would it help differentiate it from Summit and SQL Saturday? These are all questions that I think should be asked and answered before we do this event again. And we can’t do that if we don’t take time to have the discussion. I wanted to get this published before I take off for a few days of vacation. When I get back I’d like to write more about why the international events are different and talk about where we go from here.

  • SSDs at PASS 2012

    - by jchang
    There were 7 companies exhibiting SSD products as PASS this year, and one with a product to support SSD storage. This is not counting Dell, EMC and HP who have SSD products, but were at PASS for other reasons. This shows that many have aspirations with the hope that market leadership is not yet firmly set. The products fall into the following: PCI-E SSDs (Fusion-io, LSI, Virident) SSD SAN (Violin, TMS, Whiptail) SSD caching (LSI, GridIron) I am inclined to be of the opinion that SSD market is not...(read more)

  • Pass structure as an argument in c# method

    - by MegaMind
    I want to know if it is possible to pass a Structure as a parameter in c# method and if possible, is it a good practice to do so? I have a c# method which is taking six arguments, i really hate that. I could create a carrier class for that and pass it as an argument, but i want to know if structure could do the job. I want to mention here that few arguments to that method are of ref type and few are of value type.

  • Implement DDD and drawing the line between the an Entity and value object

    - by William
    I am implementing an EMR project. I would like to apply a DDD based approach to the problem. I have identified the "Patient" as being the core object of the system. I understand Patient would be an entity object as well as an aggregrate. I have also identified that every patient must have a "Doctor" and "Medical Records". The medical records would encompass Labs, XRays, Encounter.... I believe those would be entity objects as well. Let us take a Encounter for example. My implementation currently has a few fields as "String" properties, which are the complaint, assessment and plan. The other items necessary for an Encounter are vitals. I have implemented vitals as a value object. Given that it will be necessary to retrieve vitals without haveing to retrieve each Encounter then do vitals become part of the Encounter aggregate and patient aggregrate. I am assuming I could view the Encounter as an aggregrate, because other items are spwaned from the Encounter like prescriptions, lab orders, xrays. Is approach right that I am taking in identifying my entities and aggregates. In the case of vitals, they are specific to a patient, but outside of that there is not any other identity associated with them.

  • Sending wordpress title-value across PHP-pages

    - by VoodooBurger
    I recently made this wordpress blog, where you can sign up a team for an event, when clicking a link under the event post. This link takes you to a sign-up form on another php-page. The link is added in the loop of the events-template like this: <?php query_posts('cat=8');?> <?php if (have_posts()) : while (have_posts()) : the_post(); ?> <div class="post" id="post-<?php the_ID(); ?>"> <h2><a href="<?php the_permalink() ?>"><?php the_title(); ?></a></h2> <div id="tilmeldknap"><?php wp_list_pages("title_li=&depth=1&include=63"); ?></div> <?php include (TEMPLATEPATH . '/inc/meta.php' ); ?>... So every upcoming event will have the same sign-up button. All I need now is to somehow send the specific event-post-title along to the sign-page, so that the following form-submit action will contain that title aswell. But since I'm not very good at php it seems like a mystery, altho I bet it's very simple! I'm guessing it's something like: $event=$_POST['single_post_title()'] But how to get the value to the next php-page I have no idea... please help, anyone :) An eksample can be seen throught this link: http://gadebold.dk/events/ The link sais: 'Tilmeld Hold'

  • Passing Key-Value pair to a COM method in C#

    - by Sinnerman
    Hello, I have the following problem: I have a project in C# .Net where I use a third party COM component. So the problem is that the above component has a method, which takes a string and a number of key-value pairs as arguments. I already managed to call that method through JavaScript like that: var srcName srcName = top.cadView.addSource( 'Database', { driver : 'Oracle', host : '10.10.1.123', port : 1234, database : 'someSID', user : 'someuser', password : 'somepass' } ) if ( srcName != '' ) { ... } ... and it worked perfectly well. However I have no idea how to do the same using C#. I tried passing the pairs as Dictionary and Struct/Class but it throws me a "Specified cast is not valid." exception. I also tried using Hashtable like that: Hashtable args = new Hashtable(); args.Add("driver", "Oracle"); args.Add("host", "10.10.1.123"); args.Add("port", 1234); args.Add("database", "someSID"); args.Add("user", "someUser"); args.Add("password", "samePass"); String srcName = axCVCanvas.addSource("Database", args); and although it doesn't throw an exception it still won't do the job, writing me in a log file [ Error] [14:38:33.281] Cad::SourceDB::SourceDB(): missing parameter 'driver' Any help will be appreciated, thanks.

  • MySQL query against pseudo-key-value pair data in WordPress custom query

    - by andrevr
    I'm writing a custom WordPress query to use some of the data which the Woothemes Diarise theme creates. Diarise is an event planner theme with calendar blah, blah... and uses custom fields to store the event start and end dates in WP custom fields in the *wp_postmeta* table, which implements a key-value store. So for each post in the "event" category, there are 2 records in *wp_postmeta*, named *event_start_date* and *event_end_date* that I'm interested in. The task is to compare a tourist's arrival and departure dates with the start and end dates of events, yielding a what's on list of events available. We thought we'd killed it with a grand flash of logic, that goes like this: Disregard any event that ends before the tourist arrives, and any that begin after the departure date. I wrote this query: SELECT wposts.* FROM wp_posts wposts LEFT JOIN wp_postmeta wpostmeta ON wposts.ID = wpostmeta.post_id LEFT JOIN wp_term_relationships ON (wposts.ID = wp_term_relationships.object_id) LEFT JOIN wp_term_taxonomy ON (wp_term_relationships.term_taxonomy_id = wp_term_taxonomy.term_taxonomy_id) WHERE wp_term_taxonomy.taxonomy = 'category' AND wp_term_taxonomy.term_id IN(3,4) AND ( wpostmeta.meta_key = 'event_start_date' AND NOT ( concat(subst(wpostmeta.meta_value,7,4),'-',subst(wpostmeta.meta_value,4,2),'-',subst(wpostmeta.meta_value,1,2) > '2010-07-31' ) ) AND ( wpostmeta.meta_key = 'event_end_date' AND NOT ( concat(subst(wpostmeta.meta_value,7,4),'-',subst(wpostmeta.meta_value,4,2),'-',subst(wpostmeta.meta_value,1,2) < '2010-05-01' ) ) ) ORDER BY wpostmeta.meta_value ASC And, of course it returns no records. The problem I believe is in the dual reference to wpostmeta.meta_key, but how to get around that?

  • optimize output value using a class and public member

    - by wiso
    Suppose you have a function, and you call it a lot of times, every time the function return a big object. I've optimized the problem using a functor that return void, and store the returning value in a public member: #include <vector> const int N = 100; std::vector<double> fun(const std::vector<double> & v, const int n) { std::vector<double> output = v; output[n] *= output[n]; return output; } class F { public: F() : output(N) {}; std::vector<double> output; void operator()(const std::vector<double> & v, const int n) { output = v; output[n] *= n; } }; int main() { std::vector<double> start(N,10.); std::vector<double> end(N); double a; // first solution for (unsigned long int i = 0; i != 10000000; ++i) a = fun(start, 2)[3]; // second solution F f; for (unsigned long int i = 0; i != 10000000; ++i) { f(start, 2); a = f.output[3]; } } Yes, I can use inline or optimize in an other way this problem, but here I want to stress on this problem: with the functor I declare and construct the output variable output only one time, using the function I do that every time it is called. The second solution is two time faster than the first with g++ -O1 or g++ -O2. What do you think about it, is it an ugly optimization?

  • Changing Value of Array Pointer When Passed to a Function

    - by ZAX
    I have a function which receives both the array, and a specific instance of the array. I try to change the specific instance of the array by accessing one of its members "color", but it does not actually change it, as can be seen by debugging (checking the value of color after function runs in the main program). I am hoping someone can help me to access this member and change it. Essentially I need the instance of the array I'm specifying to be passed by reference if nothing else, but I'm hoping there is an easier way to accomplish what I'm trying to do. Here's the structures: typedef struct adjEdge{ int vertex; struct adjEdge *next; } adjEdge; typedef struct vertex{ int sink; int source; int color; //0 will be white, 1 will be grey, 5 will be black int number; adjEdge *nextVertex; } vertex; And here is the function: void walk(vertex *vertexArray, vertex v, int source, maxPairing *head) { int i; adjEdge *traverse; int moveVertex; int sink; traverse = vertexArray[v.number-1].nextVertex; if(v.color != 5 && v.sink == 5) { sink = v.number; v.color = 5; addMaxPair(head, source, sink); } else { walk(vertexArray, vertexArray[traverse->vertex-1], source, head); } } In particular, v.color needs to be changed to a 5, that way later after recursion the if condition blocks it.

  • How ca I return a value from a function

    - by Shadi Al Mahallawy
    I used a function to calculate information about certain instructions I intialized in a map,like this void get_objectcode(char*&token1,const int &y) { map<string,int> operations; operations["ADD"] = 18; operations["AND"] = 40; operations["COMP"] = 28; operations["DIV"] = 24; operations["J"] = 0X3c; operations["JEQ"] =30; operations["JGT"] =34; operations["JLT"] =38; operations["JSUB"] =48; operations["LDA"] =00; operations["LDCH"] =50; operations["LDL"] =55; operations["LDX"] =04; operations["MUL"] =20; operations["OR"] =44; operations["RD"] =0xd8; operations["RSUB"] =0x4c; operations["STA"] =0x0c; operations["STCH"] =54; operations["STL"] =14; operations["STSW"] =0xe8; operations["STX"] =10; operations["SUB"] =0x1c; operations["TD"] =0xe0; operations["TIX"] =0x2c; operations["WD"] =0xdc; if ((operations.find("ADD")->first==token1)||(operations.find("AND")->first==token1)||(operations.find("COMP")->first==token1) ||(operations.find("DIV")->first==token1)||(operations.find("J")->first==token1)||(operations.find("JEQ")->first==token1) ||(operations.find("JGT")->first==token1)||(operations.find("JLT")->first==token1)||(operations.find("JSUB")->first==token1) ||(operations.find("LDA")->first==token1)||(operations.find("LDCH")->first==token1)||(operations.find("LDL")->first==token1) ||(operations.find("LDX")->first==token1)||(operations.find("MUL")->first==token1)||(operations.find("OR")->first==token1) ||(operations.find("RD")->first==token1)||(operations.find("RSUB")->first==token1)||(operations.find("STA")->first==token1)||(operations.find("STCH")->first==token1)||(operations.find("STCH")->first==token1)||(operations.find("STL")->first==token1) ||(operations.find("STSW")->first==token1)||(operations.find("STX")->first==token1)||(operations.find("SUB")->first==token1) ||(operations.find("TD")->first==token1)||(operations.find("TIX")->first==token1)||(operations.find("WD")->first==token1)) { int y=operations.find(token1)->second; //cout<<hex<<y<<endl; } return ; } which if I cout y in the function gives me an answer just fine which is what i need but there is a problem tring to return the value from the function so that I could use it outside the function , it gives a whole different answer, what is the problem

  • ocjective-c Obtain return value from public method

    - by Felix
    I'm pretty new to objective-C (and C in general) and iPhone development and am coming from the java island, so there are some fundamentals that are quite tough to learn for me. I'm diving right into iOS5 and want to use storyboards. For now I am trying to setup a list in a UITableViewController that will be filled with values returned by a web service in the future. For now, I just want to generate some mock objects and show their names in the list to be able to proceed. Coming from java, my first approach would be to create a new Class that provides a global accessible method to generate some objects for my list: #import <Foundation/Foundation.h> @interface MockObjectGenerator : NSObject +(NSMutableArray *) createAndGetMockProjects; @end Implementation is... #import "MockObjectGenerator.h" // Custom object with some fields #import "Project.h" @implementation MockObjectGenerator + (NSMutableArray *) createAndGetMockObjects { NSMutableArray *mockProjects = [NSMutableArray alloc]; Project *project1 = [Project alloc]; Project *project2 = [Project alloc]; Project *project3 = [Project alloc]; project1.name = @"Project 1"; project2.name = @"Project 2"; project3.name = @"Project 3"; [mockProjects addObject:project1]; [mockProjects addObject:project2]; [mockProjects addObject:project3]; } And here is my ProjectTable.h that is supposed to control my ListView #import <UIKit/UIKit.h> @interface ProjectsTable : UITableViewController @property (strong, nonatomic) NSMutableArray *projectsList; @end And finally ProjectTable.m #import "ProjectsTable.h" #import "Project.h" #import "MockObjectGenerator.h" @interface ProjectsTable { @synthesize projectsList = _projectsList; -(id)initWithStyle:(UITableViewStyle:style { self = [super initWithStyle:style]; if (self) { _projectsList = [[MockObjectGenerator createAndGetMockObjects] copy]; } return self; } - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { // only one section for all return 1; - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { NSLog(@"%d entries in list", _projectsList.count); return _projectsList.count; - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { // the identifier of the lists prototype cell is set to this string value static NSString *CellIdentifier = @"projectCell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; Project *project = [_projectsList objectAtIndex:indexPath.row]; cell.textLabel.text = project.name } So while I think everything is correctly set, I expect the tableView to show my three mock objects in its rows. But it stays empty and the NSLog method prints "0 entries in list" into the console. So what am I doing wrong? Any help is appreciated. Best regards Felix

  • PASS: 2013 Summit Location

    - by Bill Graziano
    HQ recently posted a brief update on our search for a location for 2013.  It includes links to posts by four Board members and two community members. I’d like to add my thoughts to the mix and ask you a question.  But I can’t give you a real understanding without telling you some history first. So far we’ve had the Summit in Chicago, San Francisco, Orlando, Dallas, Denver and Seattle.  Each has a little different feel and distinct memories.  I enjoyed getting drinks by the pool in Orlando after the sessions ended.  I didn’t like that our location in Dallas was so far away from all the nightlife.  Denver was in downtown but we had real challenges with hotels.  I enjoyed the different locations.  I always enjoyed the announcement during the third keynote with the location of the next Summit. There are two big events that impacted my thinking on the Summit location.  The first was our transition to the new management company in early 2007.  The event that September in Denver was put on with a six month planning cycle by a brand new headquarters staff.  It wasn’t perfect but came off much better than I had dared to hope.  It also moved us out of the cookie cutter conferences that we used to do into a model where we have a lot more control.  I think you’ll all agree that the production values of our last few Summits have been fantastic.  That Summit also led to our changing relationship with Microsoft.  Microsoft holds two seats on the PASS Board.  All the PASS Board members face the same challenge: we all have full-time jobs and PASS comes in second place professionally (or sometimes further back).  Starting in 2008 we were assigned a liaison from Microsoft that had a much larger block of time to coordinate with us.  That changed everything between PASS and Microsoft.  Suddenly we were talking to product marketing, Microsoft PR, their event team, the Tech*Ed team, the education division, their user group team and their field sales team – locally and internationally.  We strengthened our relationship with CSS, SQLCAT and the engineering teams.  We had exposure at the executive level that we’d never had before.  And their level of participation at the Summit changed from under 100 people to 400-500 people.  I think those 400+ Microsoft employees have value at a conference on Microsoft SQL Server.  For the first time, Seattle had a real competitive advantage over other cities. I’m one that looked very hard at staying in Seattle for a long, long time.  I think those Microsoft engineers have value to our attendees.  I think the increased support that Microsoft can provide when we’re in Seattle has value to our attendees.  But that doesn’t tell the whole story.  There’s a significant (and vocal!) percentage of our membership that wants the Summit outside Seattle.  Post-2007 PASS doesn’t know what it’s like to have a Summit outside of Seattle.  I think until we have a Summit in another city we won’t really know the trade-offs. I think a model where we move every third or every other year is interesting.  But until we have another Summit outside Seattle and we can evaluate the logistics and how important it is to have depth and variety in our Microsoft participation we won’t really know. Another benefit that comes with a move is variety or diversity.  I learn more when I’m exposed to new things and new people.  I believe that moving the Summit will give a different set of people an opportunity to attend. Grant Fritchey writes “It seems that the board is leaning, extremely heavily, towards making it a permanent fixture in Seattle.”  I don’t believe that’s true.  I know there was discussion of that earlier but I don’t believe it’s true now. And that brings me to my question.  Do we announce the city now or do we wait until the 2012 Summit?  I’m happy to announce Seattle vs. not-Seattle as soon as we sign the contract.  But I’d like to leave the actual city announcement until the 2011 Summit.  I like the drama and mystery of it.  I also like that it doesn’t give you a reason to skip a Summit and wait for the next one if it’s closer or back in Seattle.  The other side of the coin is that your planning is easier if you know where it is.  What do you think?
