• Elo system behaves oddly in program I've created

  - by adc

  Alright, so I'm looking to build a small program (C# and XAML) that, essentially, does this: Generate array of players. Each player has a current rating and a true rating. I set current rating to 1200 as a starting point right now; I've also tried setting it to true rating and the average of the two. True rating is what their skill level actually is. Their true rating is calculated based on percentages from the current League of Legends rating system; generating an array of 970 thousand generates results very similar to the data from here: (removed due to URL limit - but trust me, the results are very similar). This array is of length specified by the user. If need be, sort the array from smallest to largest. Play X number of games, again specified by the user. This is done by taking the array of players (which is sorted by Current Rating after being created) and running through it in groups of 10. The first five are on team one, the second five are on team two. It then takes the True Rating of these players and calculates an expected chance to win using the Elo system. It generates a random double and compares it to the expected chance to win; if the number is lower, team one wins - otherwise team two wins. I then update the rating of the players via, again, the Elo system - giving the winning team a score of 1 and the losing team a score of 0. I use a K value of 36 (but have tried 12, 24, and even higher ones) and an F value of 400. After going through the entire loop of players (which I have conveniently forced to be a multiple of ten), it sorts the array - again via current rating. This, if my understanding of the Elo system is correct, runs properly. However, it doesn't seem to work. I have a running test telling me how many players of the full array are within 100 current rating of their true rating. I would expect some portion of the population to be outside this range (as probability is not always going to go in their favor), but a full 40-45% of the population is outside of this range. I also have it outputting the maximum difference between true and current rating - and I have never seen this drop below 500! It hovers between 550-600, occasionally going over or under. I'm at a loss as to what to change - I've fiddled with the K and F values, where I start all the players, etc. but nothing changes the fact that eventually a good 40% of the population is outside the range. And it isn't that I have it playing too few games - it's now run through over 60 thousand games and the problem never disappears or really fluctuates. The full C# code, including everything except the XAML file and the Player class (pastebin is being very slow and I can only post two links, so I can't link to the XAML file): http://pastebin.com/rFcZRL84 The Player class: http://pastebin.com/4cJTdTRu I guess my question is did I do anything wrong? Is there a problem with the way I implemented the system, or is it just that Riot uses a significantly modified Elo system? I don't think it's the latter, as that still wouldn't explain the massive true and current rating differences to me, however.

• My collection of favourite TFS utilities

  - by Aaron Kowall

  So, you’re in charge of your company or team’s Team Foundation Server.  Wish it was easier to manage, administer, extend?  Well, here are a few utilities that I highly recommend looking at. I’ve recently had need to rebuild my laptop and upgrade my local TFS environment to TFS 2012 Update 1.  This gave me cause to enumerate some of the utilities I like to have on hand. One of the reasons I love to use TFS on projects is that it’s basically a complete ALM toolkit.  Everything from Task Management, Version Control, Build Management, Test Management, Metrics and Reporting are all there ‘in the box’.  However, no matter how complete a product set it, there are always ways to make it better.  Here are a list of utilities and libraries that are pretty generally useful.  this is not intended to be an exhaustive list of TFS extensions but rather a set that I recommend you look at.  There are many more out there that may be applicable in one scenario or another.  This set of tools should work with TFS 2012 or 2010 if you grab the right version. Most of these tools (and more) are available from the Visual Studio Gallery or CodePlex. General TFS Power Tools – This is ‘the’ collection of utilities and extensions delivered by the Product Group.  Highly recommended from here are the Best Practice Analyzer for ensuring your TFS implementation is healthy and the Team Foundation Server Backups to ensure your TFS databases are backed up correctly. TFS Administrators Toolkit – helps make updates to work item types and reports across many team projects.  Also provides visibility of disk usage by finding large files in version control or test attachments to assist in managing storage utilization. Version Control Git-TF - a set of cross-platform, command line tools that facilitate sharing of changes between TFS and Git. These tools allow a developer to use a local Git repository, and configure it to share changes with a TFS server.  Great for all Git lovers who must integrate into a TFS repository. Testing TFS 2012 Tester Power Tool – A utility for bulk copying test cases which assists in an approach for managing test cases across multiple releases.  A little plug that this utility was written and maintained by Anna Russo of Imaginet where I also work. Test Scribe - A documentation power tool designed to construct documents directly from the TFS for test plan and test run artifacts for the purpose of discussion, reporting etc. Reporting Community TFS Report Extensions - a single repository of SQL Server Reporting Services report for Team Foundation 2010 (and above).  Check out the Test Plan Status report by Imaginet’s Steve St. Jean.  Very valuable for your test managers. Builds TFS Build Manager – A great utility if you are build manager over a complex build environment with many TFS build definitions. Community TFS Build Extensions – contains many custom build activities.  Current release binaries are for TFS 2010 but many of the activities can be recompiled for use with TFS 2012. While compiling this list, I was surprised by the number of TFS utilities and extensions I no longer use/need in TFS 2012 because of the great work by the TFS team addressing many gaps since the 2010 release. Are there any utilities you depend on that I’ve missed?  I’d love to hear about them in the comments!

• Experimenting with other search engines

  - by Bill Graziano

  I’ve been a Google user so long I can hardly remember what I used before it.  Alta Vista maybe?  Or Yahoo.  I’ve tried Bing off and on but it never really stuck.  I probably care more about search engines than your average user because of their impact on SQLTeam.com.  Lately I’ve been trying two other search engines and actually switched to one of them. I’ve played with Blekko a little in the past.  They have some interesting ways to “slice up” your results.  For example, searching on “SQL Server /blogs /date” should just search all the recently updated blogs.  Those two extra words on the search are slashtags.  The full list of slashtags runs from /forums to just see forums to /twitter to /nikon to /reviews and on and on and on.  I laughed when I saw they had slashtags for both liberal and conservative.  I’d hate to find any search results that don’t match my existing worldview :)  You can also create your own slashtags.  I created a mini-search engine for the SQL Server blogs that I read.  You can search it for “backup” at http://blekko.com/ws/backup+/billgraziano/sql-sites.  I uploaded my OPML and it limited the search to just those sites.  It seems like the site is focusing more on curating results and less on algorithms.  This is an interesting site for those power searchers.  There are some great ways to curate results using slashtags.  For 99% of my searches (type words, click on one of the first few links) slashtags are overkill.  They do have some good information on page and site ranking though so I’ll probably send some time looking through that. Blekko recently got my attention again when they said they were banning “content farms” - and that includes eHow and experts-exchange.  I always feel used when I click on a link to EE and find myself scrolling all the way to the bottom to see if I can find the answer.  Sometimes it’s there but sometimes it tells me I need to pay first.  I’ve longed for a way to always exclude certain sites.  Blekko might be taking a hammer to a problem that needs a scalpel but it’s an interesting choice.  (And some of the comments in the TechCrunch link are interesting if you’re a search nerd.) DuckDuckGo is an odd name for a search engine.  Their big hook is that they don’t have search history.  If you wade through your Google account you can probably find the page where it stores your search history.  It was pretty enlightening to find mine.  It was easy to disable but that got me started looking at other search engines.  DDG (or DukGo) just feels like Google used to in the old days.  The results are good enough and the site is fast. Searches will return a snippet from WikiPedia or other site (like StackOverflow) at the top.  I think the idea is to answer the question without needing to visit the site.  I’m not sure that’s a good thing for SQLTeam.com. The only thing I really miss is image search.  You can add a “!i” at the end of any search and it will search the images on Bing.  Bing doesn’t have a great image search but it works for most of what I need.  They call these exclamation marks “!bangs” and they are kinda, sorta like slashtags.  I’ve been using DuckDuckGo now for a few weeks and I’m pretty happy with it.  I use Chrome for my browser and it was an easy switch to make.  It’s still a little surprising seeing my search results come up in a different format.  I’m starting to get used to it though.

• Silverlight Binding with multiple collections

  - by George Evjen

  We're designing some sport specific applications. In one of our views we have a gridview that is bound to an observable collection of Teams. This is pretty straight forward in terms of getting Teams bound to the GridView. <telerik:RadGridView Grid.Row="0" Grid.Column="0" x:Name="UsersGrid" ItemsSource="{Binding TeamResults}" SelectedItem="{Binding SelectedTeam, Mode=TwoWay}"> <telerik:RadGridView.Columns> <telerik:GridViewDataColumn Header="Name/Group" DataMemberBinding="{Binding TeamName}" MinWidth="150"></telerik:GridViewDataColumn> </telerik:RadGridView.Columns> </telerik:RadGridView> We use the observable collection of teams as our items source and then bind the property of TeamName to the first column. You can set the binding to mode=TwoWay, we use a dialog where we edit the selected item, so our binding here is not set to two way. The issue comes when we want to bind to a property that has another collection in it. To continue on our code from above, we have an observable collection of teams, within that collection we have a collection of KeyPeople. We get this collection using RIA Serivces with the code below. return _TeamsRepository.All().Include("KeyPerson"); Here we are getting all the teams and also including the KeyPerson entity. So when we are done with our Load we will end up with an observable collection of Teams with a navigation property / entity of KeyPerson. Within this KeyPerson entity is a list of people associated with that particular team. We want to display the head coach from this list of KeyPersons. This list currently has a list of ten or more people that are bound to this team, but we just want to display the Head Coach in the column next to team name. The issue becomes how do we bind to this included entity? I have found about three different ways to solve this issue. The way that seemed to fit us best is to utilize the features within RIA Services. We can create client side properties that will do the work for us. We will create in the client side library a partial class of Team. We will end up in our library a file that is Team.shared.cs. The code below is what we will put into our partial team class. public KeyPerson Coach        {            get            {                if (this.KeyPerson != null && this.KeyPerson.Any())                { return this.KeyPerson.Where(x => x.RelationshipType == “HeadCoach”).FirstOrDefault(); }                 return null;            }        } We will return just the person that is the Head Coach and then be able to bind that and any other additional properties that we need. <telerik:GridViewDataColumn Header="Coach" DataMemberBinding="{Binding Coach.Name}" MinWidth="150"></telerik:GridViewDataColumn> There are other ways that we could have solved this issue but we felt that creating a partial class through RIA Services best suited our needs.

• Django: making raw SQL query, passing multiple/repeated params?

  - by AP257

  Hopefully this should be a fairly straightforward question, I just don't know enough about Python and Django to answer it. I've got a raw SQL query in Django that takes six different parameters, the first two of which (centreLat and centreLng) are each repeated: query = "SELECT units, (SQRT(((lat-%s)*(lat-%s)) + ((lng-%s)*(lng-%s)))) AS distance FROM places WHERE lat<%s AND lat>%s AND lon<%s AND lon>%s ORDER BY distance;" params = [centreLat,centreLng,swLat,neLat,swLng,neLng] places = Place.objects.raw(query, params) How do I structure the params object and the query string so they know which parameters to repeat and where?

• How to capture input parameters from within stored procedure (SQL Server 2005)?

  - by Duncan

  I would like to create a generic logging solution for my stored procedures, allowing me to log the values of input parameters. Currently I am doing this more or less by hand and I am very unhappy with this approach. Ideally, I would like to say something like the following: "given my spid, what are my input parameters and their values?" This is the same information exposed to me when I run SQL Profiler -- the stored procedure's name, all input params and all input VALUES are listed for me. How can I get my hands on these values from within a stored procedure? Thanks; Duncan

• bi-directional o2m/m2o beats uni-directional o2m in SQL efficiency?

  - by Henry

  Use these 2 persistent CFCs for example: // Cat.cfc component persistent="true" { property name="id" fieldtype="id" generator="native"; property name="name"; } // Owner.cfc component persistent="true" { property name="id" fieldtype="id" generator="native"; property name="cats" type="array" fieldtype="one-to-many" cfc="cat" cascade="all"; } When one-to-many (unidirectional) Note: inverse=true on unidirectional will yield undesired result: insert into cat (name) values (?) insert into Owner default values update cat set Owner_id=? where id=? When one-to-many/many-to-one (bi-directional, inverse=true on Owner.cats): insert into Owner default values insert into cat (name, ownerId) values (?, ?) Does that mean setting up bi-directional o2m/m2o relationship is preferred 'cause the SQL for inserting the entities is more efficient?

• Does SQL Server Compact Edition (SqlCe) have a SNAPSHOT table like Oracle Lite?

  - by MusiGenesis

  In Oracle Lite, you can create a SNAPSHOT table which is like a normal table except that it tracks changes to itself. The syntax is CREATE SNAPSHOT TABLE tblWhatever ... and you can perform CRUD operations on it like a normal table. To get the change information, you query the table like this: SELECT * FROM tblWhatever + WHERE ... which returns all the rows in the table (including deleted ones) meeting the WHERE clause, and you can access each row's row_state column as a normal field (which is invisible to a normal SELECT * FROM tblWhatever WHERE ... query). Is there some way to do the same thing with Sql Compact Edition (3.5) - i.e. create a table that tracks changes without using RDA?

• Erlang Mnesia Equivalent of SQL Select FROM WHERE Field IN (value1, value2, value3, ...)

  - by ErJab

  I have an mnesia table with fields say f1, f2, f3. Now if I were to select all the rows with the field value as V1, I would use mnesia:select and match specifications or a simple mnesia:match_object. Now I need to select all the rows which have V1, V2, V3 ... or Vn (a list of arbitrary length) as the value for field f1. In SQL I would do something like SELECT * FROM tablename WHERE f3 IN (V1, V2, V3, ... , Vn) How do I do this in mnesia?

• What are good educational resources for setting up .Net Webservice on a DMZ connecting to SQL Server

  - by Brian

  We are going to begin implementing a web service that will be hosted on a DMZ server. This web server will post data to a SQL server and we're trying to determine the best methodology to handle this. Things that concern us are web service authentication, SOAP, and whether or not to store the database on the DMZ or the local network. This same scenario will apply to ASP.Net apps. Trust me, I've already searched the web, but as usual, the online resources I've found either talk about just authentication, or just about SOAP, or etc, but does not show or suggest how the entire system can work together. Can you give me a list of resources such as links that I've missed, books, classes, or etc that would help? Thank You.

• Is there a more expressive way of executing SQL query using Qt?

  - by ShaChris23

  I currently have this code: // Construct query QString const statement = QString("drop database if exists %1") .arg(databaseName_); QSqlQuery query(db); query.exec(statement); Is there a better way to code than the above? Specifically, I dont like how I use QString for SQL statement. It'd be nice if Qt has some class so that I could do something like: // Construct query QSomeClass statement = "drop database if exists %1"; statement.setArg(1, databaseName_); // Replace all %1 in the original string. QSqlQuery query(db); query.exec(statement);

• Retrieve entities with children per one sql call. ADO.NET Entity framework

• What are the best blogs for staying up to date on C#, ASP.NET, LINQ, SQL, C++, Ruby, Java, Python?

  - by Arj

  Apologies if this repeats another - but I couldn't fine one like it. My day to day programming spans a fair number of technologies: C#, ASP.NET, LINQ / SQL, C++, Ruby, Java, Python in approximately that order. It's a struggle to keep up to date on any of best practices, new ideas, innovation and improvements, let alone all. Therefore, what would your top 1 blog be in each of these technologies and which technology do you find easiest to stay up to date with? I'd have a bias towards blogs with broad and high level rather than narrow and detailed content / solutions / examples.

  How do I find the maximum (or minimum) of two integers in Postgres/SQL? One of the integers is not a column value. I will give an example scenario: I would like to subtract an integer from a column (in all rows), but the result should not be less than zero. So, to begin with, I have: UPDATE my_table SET my_column = my_column - 10; But this can make some of the values negative. What I would like (in pseudo code) is: UPDATE my_table SET my_column = MAXIMUM(my_column - 10, 0);

• How do I get the median/mode/range of a column in SQL using Java?

  - by Derek

  I have to get the median, mode and range of test scores from one column in a table but I am unsure how to go about doing that. When you connect to the database using java, you are normally returned a ResultSet that you can make a table or something out of but how do you get particular numbers or digits? Is there an SQL command to get the median/mode/range or will I have to calculate this myself, and how do you pull out numbers from the table in order to be able to calculate the mode/median/range? Thanks.
