• Will adding top level directories with similar structure to existing directories change the SEO of my site?

  - by Russell Sims

  I've been pointed this way for SEO related questions and this one has had me pondering for a little while now. I'm recreating a site's structure. The website's content is generated through several feeds and unless I want to place each and every - of the 10,000 odd - venues into their own category manually, I can't avoid categorising each item by using its address. The current the structure looks like this Homepage > region > county > city/town > venue page and the URL looks like domain/region/county/city/venue/ I'm relatively happy to use this structure as it's not too convoluted. However we also promote deals and we also group the venues into their respective franchise, so that leads to URLs such as: domain/groups AND domain/deals My question is: how would the directory structure look with these new additions? Would I have a URL that looks like domain/deals/region/county/city/venue or domain/group/region/county/city/venue and just put a 301 or a canonical link tag on the page to prevent the duplicate pages competing with each other? Am I just worrying about it needlessly and perhaps link straight from domain/deals to the venue page URL domain/region/county/city/venue, this bothers me a bit though as the deals and groups will not be in the breadcrumbs.

• Algorithm allowing a good waypoint path following?

  - by Thierry Savard Saucier

  I'm more looking into how should I implement this, either a tutorial or even the name of the concept I'm missing. I'm pretty sure some basic pathfinding algorithm could help me here, but I dont know which one ... I have a worldmap, with different cities on it. The player can choose a city from a menu, or click on an available cities on the world map, and the toon should walk over there. But I want him to follow a predefine path. Lets say our hero is on the city 1. He clicks on city 4. I want him to follow the path to city 2 and from there to city 4. I was handling this easily with arrow movement (left right top bottom) since its a single check. Now I'm not sure how I should do this. Should I loop threw each possible path and check which one leads me to D the fastest ... and if I do how do I avoid running in circle forever with cities 1-5-2 ?

• Game Resource Generation

  - by Darthg8r

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

• Designing rules to fight smallpox in Civ-style TBS games

  - by Williham Totland

  TL;DR: How do you design a ruleset for a Civ-style TBS game that prevents city smallpox from being a profitable or viable strategy? Long version: Civ-style games are pretty great. Bringing a civilization from cradle to grave is a great endeavor, and practicing diplomacy with hard-line human players is fun and challenging. In theory. In practice, however, many of these games has, especially in multiplayer, exactly one viable strategy: City smallpox, a.k.a. infinite city spread, a.k.a. covering all available space with 1-citizen cities, packed as tight as they will go. I suppose this could count as emergent gameplay, but still; it could hardly be considered to be in the spirit of the class of game. The Civilization series, of course, is stuck in their more or less fixed rule sets, established with Civilization. Yes, there have been major changes in some respects, but the rules pertaining to city building and maintenance have stayed pretty similar. So the question, then: If you build a ruleset for a TBS from the ground up; what rules should be in place to prevent Infinite City Sprawl from being a viable strategy? Or should ICS be a viable strategy?

• nginx rewrite rule for using domain host to redirect to specific internal directory

  - by user85836

  I'm new to Nginx rewrites and looking for help in getting a working and minimal rewrite code. We would like to use urls like 'somecity.domain.com' on campaign materials and have the result go to city-specific content within the 'www' site. So, here are use cases, if the customer enters: www.domain.com (stays) www.domain.com domain.com (goes to) www.domain.com www.domain.com/someuri (stays the same) somecity.domain.com (no uri, goes to) www.domain.com/somecity/prelaunch somecity.domain.com/landing (goes to) www.domain.com/somecity/prelaunch somecity.domain.com/anyotheruri (goes to) www.domain.com/anyotheruri Here's what I've come up with so far, and it partially works. What I can't understand is how to check if there is no path/uri after the host, and I'm guessing there is probably a way better way to do this. if ($host ~* ^(.*?)\.domain\.com) { set $city $1;} if ($city ~* www) { break; } if ($city !~* www) { rewrite ^/landing http://www.domain.com/$city/prelaunch/$args permanent; rewrite (.*) http://www.domain.com$uri$args permanent; }

• Microsoft Excel IF/THEN statement for Words

  - by user1667462

  Right now I have an excel spreadsheet. In Cells A1 and down I have cities listed. In Cells B1 and down I have some generic information with the word CITY in it. What I want to know if there is a formula to replace the word CITY that is in the contents of Cell B1 with the contents in Cell A1. For instance... Cell A1 has "Daytona Beach, FL" Cell B1 has "Compare mortgage & refinance rates from different mortgage lenders and brokers in CITY. Find the home refinance rate you were looking for in CITY." I need a formula that replaces "CITY" in B1 with "Dayton Beach, FL" in A1. Is this possible? Thank you for your help!

• how to enrich my programming background? [on hold]

  - by city

  I am not sure whether I post my question in right place. I am a master student in computer science and I will graduate next year.Recently, I failed in an interview. Because (at least I think) the interviewer did not think my background strong enough although I finished 5 courses projects and currently working on other 2 projects in graduate school. It seems that nowadays, recruiters like these candidates who finish some projects out of school/work. So I wanna enrich my background. So, I hope you guys recommend some java/C++ projects to me, which I can finish in two or three months. And it would be better if concurrency programming or other fancy skills are needed.

• Help With Database Layout

  - by three3

  Hello everyone, I am working on a site similar to Craigslist where users can make postings and sell items in different cities. One difference between my site and Craigslist will be you will be able to search by zip code instead of having all of the cities listed on the page. I already have the ZIP Code database that has all of the city, state, latitude, longitude, and zip code info for each city. Okay, so to dive into what I need done and what I need help with: 1.) Although I have the ZIP Code database, it is not setup perfectly for my use. (I downloaded it off of the internet for free from http://zips.sourceforge.net/) 2.) I need help setting up my database structure (Ex: How many different tables should I use and how should I link them) I will be using PHP and MySQL. These our my thoughts so far on how the database can be setup: (I am not sure if this will work though.) Scenario: Someone goes to the homepage and it will tell them, "Please enter your ZIP Code.". If they enter "17241" for example, this ZIP Code is for a city named Newville located in Pennsylvania. The query would look like this with the current database setup: SELECT city FROM zip_codes WHERE zip = 17241; The result of the query would be "Newville". The problem I see here now is when they want to post something in the Newville section of the site, I will have to have an entire table setup just for the Newville city postings. There are over 42,000 cities which means I would have to have over 42,000 tables (one for each city) so that would be insane to have to do it that way. One way I was thinking of doing it was to add a column to the ZIP Code database called "city_id" which would be a unique number assigned to each city. So for example, the city Newville would have a city_id of 83. So now if someone comes and post a listing in the city Newville I would only need one other table. That one other table would be setup like this: CREATE TABLE postings ( posting_id INT NOT NULL AUTO_INCREMENT, for_sale LONGTEXT NULL, for_sale_date DATETIME NULL, for_sale_city_id INT NULL, jobs LONGTEXT NULL, jobs_date DATETIME NULL, jobs_city_id INT NULL, PRIMARY KEY(posting_id) ); (The for_sale and job_ column names are categories of the types of postings users will be able to list under. There will be many more categories than just those two but this is just for example.) So now when when someone comes to the website and they are looking for something to buy and not sell, they can enter their ZIP Code, 17241, for example, and this is the query that will run: SELECT city, city_id FROM zip_codes WHERE zip = 17241; //Result: Newville 83 (Please note that I will be using PHP to store the ZIP Code the user enters in SESSIONS and Cookies to remember them throughout the site) Now it will tell them, "Please choose your category.". If they choose the category "Items For Sale" then this is the query to run and sort the results: SELECT posting_id, for_sale, for_sale_date FROM postings WHERE for_sale_city_id = $_SESSION['zip_code']; Will this work? So now my question to everyone is will this work? I am pretty sure it will but I do not want to set this thing up and realize I overlooked something and have to start from all over from scratch. Any opinions and ideas are welcomed and I will listen to anyone who has some thoughts. I really appreciate the help in advance :D

• Getting Segmentation Fault in C++, but why?

• .NET MVC custom routing with empty parameters

  - by user135498

  Hi All, I have a .net mvc with the following routes: routes.Add(new Route( "Lookups/{searchtype}/{inputtype}/{firstname}/{middlename}/{lastname}/{city}/{state}/{address}", new RouteValueDictionary( new { controller = "Lookups", action = "Search", firstname = (string)null, middlename = (string)null, lastname = (string)null, city = (string)null, state = (string)null, address = (string)null, SearchType = SearchType.PeopleSearch, InputType = InputType.Name }), new MvcRouteHandler()) ); routes.Add(new Route( "Lookups/{searchtype}/{inputtype}", new RouteValueDictionary( new { controller = "Lookups", action = "Search", firstname = "", middlename = "", lastname = "", city = "", state = "", address = "" }), new MvcRouteHandler()) ); routes.Add(new Route( "Lookups/{searchtype}/{inputtype}", new RouteValueDictionary( new { controller = "Lookups", action = "Search", firstname = "", middlename = "", lastname = "", city = "", state = "", address = "", SearchType = SearchType.PeopleSearch, InputType = InputType.Name }), new MvcRouteHandler()) ); routes.MapRoute( "Default", // Route name "{controller}/{action}/{id}", // URL with parameters new { controller = "Account", action = "LogOn", id = "" } // Parameter defaults ); The following request works fine: http://localhost:2608/Lookups/PeopleSearch/Name/john/w/smith/seattle/wa/123 main This request does not work: http://localhost:2608/Lookups/PeopleSearch/Name/john//smith//wa/ Not all requests will have all paramters and I would like empty parameters to be passed to the method as empty string or null.

• rails semi-complex STI with ancestry data model planning the routes and controllers

  - by ere

  I'm trying to figure out the best way to manage my controller(s) and models for a particular use case. I'm building a review system where a User may build a review of several distinct types with a Polymorphic Reviewable. Country (has_many reviews & cities) Subdivision/State (optional, sometimes it doesnt exist, also reviewable, has_many cities) City (has places & review) Burrow (optional, also reviewable ex: Brooklyn) Neighborhood (optional & reviewable, ex: williamsburg) Place (belongs to city) I'm also wondering about adding more complexity. I also want to include subdivisions occasionally... ie for the US, I might add Texas or for Germany, Baveria and have it be reviewable as well but not every country has regions and even those that do might never be reviewed. So it's not at all strict. I would like it to as simple and flexible as possible. It'd kinda be nice if the user could just land on one form and select either a city or a country, and then drill down using data from say Foursquare to find a particular place in a city and make a review. I'm really not sure which route I should take? For example, what happens if I have a Country, and a City... and then I decide to add a Burrow? Could I give places tags (ie Williamsburg, Brooklyn) belong_to NY City and the tags belong to NY? Tags are more flexible and optionally explain what areas they might be in, the tags belong to a city, but also have places and be reviewable? So I'm looking for suggestions for anyone who's done something related. Using Rails 3.2, and mongoid.

• SQL Server 2008 - Keyword search using table Join

  - by Aaron Wagner

  Ok, I created a Stored Procedure that, among other things, is searching 5 columns for a particular keyword. To accomplish this, I have the keywords parameter being split out by a function and returned as a table. Then I do a Left Join on that table, using a LIKE constraint. So, I had this working beautifully, and then all of the sudden it stops working. Now it is returning every row, instead of just the rows it needs. The other caveat, is that if the keyword parameter is empty, it should ignore it. Given what's below, is there A) a glaring mistake, or B) a more efficient way to approach this? Here is what I have currently: ALTER PROCEDURE [dbo].[usp_getOppsPaged] @startRowIndex int, @maximumRows int, @city varchar(100) = NULL, @state char(2) = NULL, @zip varchar(10) = NULL, @classification varchar(15) = NULL, @startDateMin date = NULL, @startDateMax date = NULL, @endDateMin date = NULL, @endDateMax date = NULL, @keywords varchar(400) = NULL AS BEGIN SET NOCOUNT ON; ;WITH Results_CTE AS ( SELECT opportunities.*, organizations.*, departments.dept_name, departments.dept_address, departments.dept_building_name, departments.dept_suite_num, departments.dept_city, departments.dept_state, departments.dept_zip, departments.dept_international_address, departments.dept_phone, departments.dept_website, departments.dept_gen_list, ROW_NUMBER() OVER (ORDER BY opp_id) AS RowNum FROM opportunities JOIN departments ON opportunities.dept_id = departments.dept_id JOIN organizations ON departments.org_id=organizations.org_id LEFT JOIN Split(',',@keywords) AS kw ON (title LIKE '%'+kw.s+'%' OR [description] LIKE '%'+kw.s+'%' OR tasks LIKE '%'+kw.s+'%' OR requirements LIKE '%'+kw.s+'%' OR comments LIKE '%'+kw.s+'%') WHERE ( (@city IS NOT NULL AND (city LIKE '%'+@city+'%' OR dept_city LIKE '%'+@city+'%' OR org_city LIKE '%'+@city+'%')) OR (@state IS NOT NULL AND ([state] = @state OR dept_state = @state OR org_state = @state)) OR (@zip IS NOT NULL AND (zip = @zip OR dept_zip = @zip OR org_zip = @zip)) OR (@classification IS NOT NULL AND (classification LIKE '%'+@classification+'%')) OR ((@startDateMin IS NOT NULL AND @startDateMax IS NOT NULL) AND ([start_date] BETWEEN @startDateMin AND @startDateMax)) OR ((@endDateMin IS NOT NULL AND @endDateMax IS NOT NULL) AND ([end_date] BETWEEN @endDateMin AND @endDateMax)) OR ( (@city IS NULL AND @state IS NULL AND @zip IS NULL AND @classification IS NULL AND @startDateMin IS NULL AND @startDateMax IS NULL AND @endDateMin IS NULL AND @endDateMin IS NULL) ) ) ) SELECT * FROM Results_CTE WHERE RowNum >= @startRowIndex AND RowNum < @startRowIndex + @maximumRows; END

• SQL: Order randomly when inserting objects to a table

  - by Ekaterina

  I have an UDF that selects top 6 objects from a table (with a union - code below) and inserts it into another table. (btw SQL 2005) So I paste the UDF below and what the code does is: selects objects for a specific city and add a level to those (from table Europe) union that selection with a selection from the same table for objects that are from the same country and add a level to those From the union, selection is made to get top 6 objects, order by level, so the objects from the same city will be first, and if there aren't any available, then objects from the same country will be returned from the selection. And my problem is, that I want to make a random selection to get random objects from table Europe, but because I insert the result of my selection into a table, I can't use order by newid() or rand() function because they are time-dependent, so I get the following errors: Invalid use of side-effecting or time-dependent operator in 'newid' within a function. Invalid use of side-effecting or time-dependent operator in 'rand' within a function. UDF: ALTER FUNCTION [dbo].[Objects] (@id uniqueidentifier) RETURNS @objects TABLE ( ObjectId uniqueidentifier NOT NULL, InternalId uniqueidentifier NOT NULL ) AS BEGIN declare @city varchar(50) declare @country int select @city = city, @country = country from Europe where internalId = @id insert @objects select @id, internalId from ( select distinct top 6 [level], internalId from ( select top 6 1 as [level], internalId from Europe N4 where N4.city = @city and N4.internalId != @id union select top 6 2 as [level], internalId from Europe N5 where N5.countryId = @country and N5.internalId != @id ) as selection_1 order by [level] ) as selection_2 return END If you have fresh ideas, please share them with me. (Just please, don't suggest to order by newid() or to add a column rand() with seed DateTime (by ms or sthg), because that won't work.)

• Optimize a MySQL count each duplicate Query

  - by Onema

  I have the following query That gets the city name, city id, the region name, and a count of duplicate names for that record: SELECT Country_CA.City AS currentCity, Country_CA.CityID, globe_region.region_name, ( SELECT count(Country_CA.City) FROM Country_CA WHERE City LIKE currentCity ) as counter FROM Country_CA LEFT JOIN globe_region ON globe_region.region_id = Country_CA.RegionID AND globe_region.country_code = Country_CA.CountryCode ORDER BY City This example is for Canada, and the cities will be displayed on a dropdown list. There are a few towns in Canada, and in other countries, that have the same names. Therefore I want to know if there is more than one town with the same name region name will be appended to the town name. Region names are found in the globe_region table. Country_CA and globe_region look similar to this (I have changed a few things for visualization purposes) CREATE TABLE IF NOT EXISTS `Country_CA` ( `City` varchar(75) NOT NULL DEFAULT '', `RegionID` varchar(10) NOT NULL DEFAULT '', `CountryCode` varchar(10) NOT NULL DEFAULT '', `CityID` int(11) NOT NULL DEFAULT '0', PRIMARY KEY (`City`,`RegionID`), KEY `CityID` (`CityID`) ) ENGINE=MyISAM DEFAULT CHARSET=utf8; AND CREATE TABLE IF NOT EXISTS `globe_region` ( `country_code` char(2) COLLATE utf8_unicode_ci NOT NULL, `region_code` char(2) COLLATE utf8_unicode_ci NOT NULL, `region_name` varchar(50) COLLATE utf8_unicode_ci NOT NULL, PRIMARY KEY (`country_code`,`region_code`) ) ENGINE=MyISAM DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci; The query on the top does exactly what I want it to do, but It takes way too long to generate a list for 5000 records. I would like to know if there is a way to optimize the sub-query in order to obtain the same results faster. the results should look like this City CityID region_name counter sheraton 2349269 British Columbia 1 sherbrooke 2349270 Quebec 2 sherbrooke 2349271 Nova Scotia 2 shere 2349273 British Columbia 1 sherridon 2349274 Manitoba 1

• Calculating a total cost in Python

  I'm trying to create a trip planner in python, but after I defined all the functions I'm not able to call and calculate them in the last function tripCost(). In tripCost, I want to put the days and travel destination (city) and the program runs the functions and gives me the exact result of all the 3 functions previously defined.

O LINQ foi lançado com a versão 3.0 na plataforma .NET, apresentando uma maneira muito mais fácil e segura de manipular coleções IEnumerable ou IEnumerable<T>. O que veremos hoje é a “alteração” do LINQ to Objects, que é direcionado a coleções de objetos em memória. A principal diferença entre o LINQ to Objects “normal” e o paralelo é que na segunda opção o processamento é realizado tentando utilizar todos os recursos disponíveis para tal, obtendo uma melhora significante de performance. CUIDADO: Nem todas as operações ficam mais rápidas utilizando recursos de paralelismo. Não deixe de ler a seção “Performance” abaixo. ParallelEnumerable Tudo que a gente precisa para este post está organizado na classe ParallelEnumerable. Esta classe contém os métodos que iremos utilizar neste post, e muito mais: AsParallel AsSequential AsOrdered AsUnordered WithCancellation WithDegreeOfParallelism WithMergeOptions WithExecutionMode ForAll … O exemplo mais básico de como executar um código PLINQ é utilizando o métodos AsParallel, como o exemplo: var source = Enumerable.Range(1, 10000); var evenNums = from num in source.AsParallel() where Compute(num) > 0 select num; Algo tão interessante quanto esta facilidade é que o PLINQ não executa sempre de forma paralela. Dependendo da situação e da análise de alguns itens no cenário de execução, talvez seja mais adequado executar o código de forma sequencial – e nativamente o próprio PLINQ faz esta escolha.  É possível forçar a execução para sempre utilizar o paralelismo, caso seja necessário. Utilize o método WithExecutionMode no seu código PLINQ. Um teste muito simples onde podemos visualizar a diferença é demonstrado abaixo: static void Main(string[] args) { IEnumerable<int> numbers = Enumerable.Range(1, 1000); IEnumerable<int> results = from n in numbers.AsParallel() where IsDivisibleByFive(n) select n; Stopwatch sw = Stopwatch.StartNew(); IList<int> resultsList = results.ToList(); Console.WriteLine("{0} itens", resultsList.Count()); sw.Stop(); Console.WriteLine("Tempo de execução: {0} ms", sw.ElapsedMilliseconds); Console.WriteLine("Fim..."); Console.ReadKey(true); } static bool IsDivisibleByFive(int i) { Thread.SpinWait(2000000); return i % 5 == 0; }   Basta remover o AsParallel da instrução LINQ que você terá uma noção prática da diferença de performance. 1. Instrução utilizando AsParallel   2. Instrução sem utilizar paralelismo Performance Apesar de todos os benefícios, não podemos utilizar PLINQ sem conhecer todos os seus detalhes. Lembre-se de fazer as perguntas básicas: Eu tenho trabalho suficiente que justifique utilizar paralelismo? Mesmo com o overhead do PLINQ, vamos ter algum benefício? Por este motivo, visite este link e conheça todos os aspectos, antes de utilizar os recursos disponíveis. Conclusão Utilizar recursos de paralelismo é ótimo, aumenta a performance, utiliza o investimento realizado em hardware – tudo isso sem custo de produtividade. Porém, não podemos usufruir de qualquer tipo de tecnologia sem conhece-la a fundo antes. Portanto, faça bom uso, mas não esqueça de manter o conhecimento a frente da empolgação. Abraços.

• Solaris 11 Update 1 - Link Aggregation

  - by Wesley Faria

  Solaris 11.1 No início desse mês em um evento mundial da Oracle chamado Oracle Open World foi lançada a nova release do Solaris 11. Ela chega cheia de novidades, são aproximadamente 300 novas funcionalidade em rede, segurança, administração e outros. Hoje vou falar de uma funcionalidade de rede muito interessante que é o Link Aggregation. O Solaris já suporta Link Aggregation desde Solaris 10 Update 1 porem no Solaris 11 Update 1 tivemos incrementos significantes. O Link Aggregation como o próprio nome diz, é a agregação de mais de uma inteface física de rede em uma interface lógica .Veja agumas funcionalidade do Link Aggregation: · Aumentar a largura da banda; · Imcrementar a segurança fazendo Failover e Failback; · Melhora a administração da rede; O Solaris 11.1 suporta 2(dois) tipos de Link Aggregation o Trunk aggregation e o Datalink Multipathing aggregation, ambos trabalham fazendo com que o pacote de rede seja distribuído entre as intefaces da agregação garantindo melhor utilização da rede.vamos ver um pouco melhor cada um deles. Trunk Aggregation O Trunk Aggregation tem como objetivo aumentar a largura de banda, seja para aplicações que possue um tráfego de rede alto seja para consolidação. Por exemplo temos um servidor que foi adquirido para comportar várias máquinas virtuais onde cada uma delas tem uma demanda e esse servidor possue 2(duas) placas de rede. Podemos então criar uma agregação entre essas 2(duas) placas de forma que o Solaris 11.1 vai enchergar as 2(duas) placas como se fosse 1(uma) fazendo com que a largura de banda duplique, veja na figura abaixo: A figura mostra uma agregação com 2(duas) placas físicas NIC 1 e NIC 2 conectadas no mesmo switch e 2(duas) interfaces virtuais VNIC A e VNIC B. Porem para que isso funcione temos que ter um switch com suporte a LACP ( Link Aggregation Control Protocol ). A função do LACP é fazer a aggregação na camada do switch pois se isso não for feito o pacote que sairá do servidor não poderá ser montado quando chegar no switch. Uma outra forma de configuração do Trunk Aggregation é o ponto-a-ponto onde ao invéz de se usar um switch, os 2 servidores são conectados diretamente. Nesse caso a agregação de um servidor irá falar diretamente com a agregação do outro garantindo uma proteção contra falhas e tambem uma largura de banda maior. Vejamos como configurar o Trunk Aggregation: 1 – Verificando quais intefaces disponíveis # dladm show-link 2 – Verificando interfaces # ipadm show-if 3 – Apagando o endereçamento das interfaces existentes # ipadm delete-ip <interface> 4 – Criando o Trunk aggregation # dladm create-aggr -L active -l <interface> -l <interface> aggr0 5 – Listando a agregação criada # dladm show-aggr Data Link Multipath Aggregation Como vimos anteriormente o Trunk aggregation é implementado apenas 1(um) switch que possua suporte a LACP portanto, temos um ponto único de falha que é o switch. Para solucionar esse problema no Solaris 10 utilizavamos o IPMP ( IP Multipathing ) que é a combinação de 2(duas) agregações em um mesmo link ou seja, outro camada de virtualização. Agora com o Solaris 11 Update 1 isso não é mais necessário, voce pode ter uma agregação de 2(duas) interfaces físicas e cada uma conectada a 1(um) swtich diferente, veja a figura abaixo: Temos aqui uma agregação chamada aggr contendo 4(quatro) interfaces físicas sendo que as interfaces NIC 1 e NIC 2 estão conectadas em um Switch e as intefaces NIC 3 e NIC 4 estão conectadas em outro Swicth. Além disso foram criadas mais 4(quatro) interfaces virtuais vnic A, vnic B, vnic C e vnic D que podem ser destinadas a diferentes aplicações/zones. Com isso garantimos alta disponibilidade em todas a camadas pois podemos ter falhas tanto em switches, links como em interfaces de rede físicas. Para configurar siga os mesmo passos da configuração do Trunk Aggregation até o passo 3 depois faça o seguinte: 4 – Criando o Trunk aggregation # dladm create-aggr -m haonly -l <interface> -l <interface> aggr0 5 – Listando a agregação criada # dladm show-aggr Depois de configurado seja no modo Trunk aggregation ou no modo Data Link Multipathing aggregation pode ser feito a troca de um modo para o outro, pode adcionar e remover interfaces físicas ou vituais. Bem pessoal, era isso que eu tinha para mostar sobre a nova funcionalidade do Link Aggregation do Solaris 11 Update 1 espero que tenham gostado, até uma próxima novidade.

• Cannot resolve TargetName - Silverlight4 C#

  - by Redburn

  I am getting the error Cannot resolve TargetName grdGeneral. What I am trying to do is have a fade out function which accepts a grid and fades the opacity to zero. I have this function called on MouseLeftButtonDown and is loaded after the xaml and form has loaded. Calling the fade out: private void imgNext_MouseLeftButtonDown(object sender, MouseButtonEventArgs e) { fadeOut(grdGeneral); } The fade out function: private void fadeOut(Grid pGrid) { Storyboard stb = new Storyboard(); DoubleAnimation da = new DoubleAnimation(); da.From = 1.0; da.To = 0.0; stb.Duration = new Duration(TimeSpan.FromSeconds(.75)); stb.Children.Add(da); Storyboard.SetTargetName(da, pGrid.Name); Storyboard.SetTargetProperty(da, new PropertyPath(Grid.OpacityProperty)); stb.Begin(); } I have been on a handful of tutorial sites and my code seems to follow the same order. I also have been on this stackoverflow question before you say repost. That question has to deal with mutlipages and I am merely trying to start a animation. The Stack Trace System.InvalidOperationException was unhandled by user code Message=Cannot resolve TargetName grdGeneral.

• Using OLEDB parameters in .NET when connecting to an AS400/DB2

  - by Jeff Stock

  I have been pulling my hair out trying to figure out what I can't get parameters to work in my query. I have the code written in VB.NET trying to do a query to an AS/400. I have IBM Access for Windows installed and I am able to get queries to work, just not with parameters. Any time I include a parameter in my query (ex. @MyParm) it doesn't work. It's like it doesn't replace the parameter with the value it should be. Here's my code: I get the following error: SQL0206: Column @MyParm not in specified tables Here's my code: Dim da As New OleDbDataAdapter Dim dt As New DataTable da.SelectCommand = New OleDbCommand da.SelectCommand.Connection = con da.SelectCommand.CommandText = "SELECT * FROM MyTable WHERE Col1 = @MyParm" With da.SelectCommand.Parameters .Add("@MyParm", OleDbType.Integer, 9) .Item("@MyParm").Value = 5 End With ' I get the error here of course da.Fill(dt) I can replace @MyParm with a literal of 5 and it works fine. What am I missing here? I do this with SQL Server all the time, but this is the first time I am attempting it on an AS400.
