  • How does Nike's website do this Flash effect when the user selects a choice.

    - by Luis Armando
    I was wondering how does Nike website make the change you can see when selecting a color or a sole. At first I thought they were only using images and when the user picked a color you just replaced that part, but when I selected a different sole I noticed it didn't changed like an image it looked a bit more as if it was being rendered. Does anybody happens to know how this is made? Or where can I get further info about making this effect :)?

  • multiple stateful iframes per page will overwrite JSESSIONID?

    - by Nikita
    Hello, Looking for someone to either confirm or refute my theory that deploying two iframes pointing to two different stateful pages on the same domain can lead to JSESSIONIDs being overwritten. Here's what I mean: Setup suppose you have two pages that require HttpSession state (session affinity) to function correctly - deployed at http://www.foo.com/page1 and http://www.foo.com/page2 assume www.foo.com is a single host running a Tomcat (6.0.20, fwiw) that uses JSESSIONID for session id's. suppose these pages are turned into two iframe widgets to be embedded on 3rd party sites: http://www.site.com/page1" / (and /page2 respectively) suppose there a 3rd party site that wishes to place both widgets on the same page at http://www.bar.com/foowidgets.html Can the following race condition occur? a new visitor goes to http://www.bar.com/foowidgets.html browser starts loading URLs in foowidgets.html including the two iframe 'src' URLs because browsers open multiple concurrent connections against the same host (afaik up to 6 in chrome/ff case) the browser happens to simultaneously issue requests for http://www.foo.com/page1 and http://www.foo.com/page2 The tomcat @ foo.com receives both requests at about the same time, calls getSession() for the first time (on two different threads) and lazily creates two HttpSessions and, thus, two JSESSIONIDs, with values $Page1 and $Page2. The requests also stuff data into respective sessions (that data will be required to process subsequent requests) assume that the browser first receives response to the page1 request. Browser sets cookie JSESSIONID=$Page1 for HOST www.foo.com next response to the page2 request is received and the browser overwrites cookie JSESSIONID for HOST www.foo.com with $Page2 user clicks on something in 'page1' iframe on foowidgets.html; browser issues 2nd request to http://www.foo.com/page1?action=doSomethingStateful. That request carries JSESSIONID=$Page2 (and not $Page1 - because cookie value was overwritten) when foo.com receives this request it looks up the wrong HttpSession instance (because JSESSIONID key is $Page2 and NOT $Page1). Foobar! Can the above happen? I think so, but would appreciate a confirmation. If the above is clearly possible, what are some solutions given that we'd like to support multiple iframes per page? We don't have a firm need for the iframes to share the same HttpSession, though that would be nice. In the event that the solution will still stipulate a separate HttpSession per iframe, it is - of course - mandatory that iframe 1 does not end up referencing httpSession state for iframe 2 instead of own. off top of my head I can think of: map page1 and page2 to different domains (ops overhead) use URL rewriting and never cookies (messes up analytics) anything else? thanks a lot, -nikita

  • Cache the result of a MySQLdb database query in memory

    - by ensnare
    Our application fetches the correct database server from a pool of database servers. So each query is really 2 queries, and they look like this: Fetch the correct DB server Execute the query We do this so we can take DB servers online and offline as necessary, as well as for load-balancing. But the first query seems like it could be cached to memory, so it only actually queries the database every 5 or 10 minutes or so. What's the best way to do this? Thanks.

  • ModalPopup inside the UpdatePanel with default form values

    - by prometeus
    I have a ModalPopupExtender inside an UpdatePanel which opens an input form. The problem is when I click the "Edit" button (which is also inside the UpdatePanel) I want to fill the form with existing values using server side code. But it OnClick method of the button doesn't seem to work. My question is: How can I make the serverside code run first, than show the edit form?

Installing the Windows Phone 7 SDK I get the following error Incompatible Products VC 10.0 Runtime .NET Framework 4 Multi-Targeting Pack Microsoft.NET Framework 4 Client Profile Microsoft .NET Framework 4 Extended This was reported as an issue with Beta 2 and the fix was to install the RC. Anyone know why it's incompatible with the RTM? Will we have to wait for an update to the SDK? Regards, Alex..

  • How do I correctly organize output into columns?

    - by wrongusername
    The first thing that comes to my mind is to do a bunch of \t's, but that would cause words to be misaligned if any word is longer than any other word by a few characters. For example, I would like to have something like: Name Last Name Middle initial Bob Jones M Joe ReallyLongLastName T Instead, by including only "\t"'s in my cout statement I can only manage to get Name Last Name Middle initial Bob Jones M Joe ReallyLongLastName T or Name Last Name Middle initial Bob Jones M Joe ReallyLongLastName T What else would I need to do?

  • How does mysql define DISTINCT() in reference documentation

    - by goran
    EDIT: This question is about finding definitive reference to MySQL syntax on SELECT modifying keywords and functions. /EDIT AFAIK SQL defines two uses of DISTINCT keywords - SELECT DISTINCT field... and SELECT COUNT(DISTINCT field) ... However in one of web applications that I administer I've noticed performance issues on queries like SELECT DISTINCT(field1), field2, field3 ... DISTINCT() on a single column makes no sense and I am almost sure it is interpreted as SELECT DISTINCT field1, field2, field3 ... but how can I prove this? I've searched mysql site for a reference on this particular syntax, but could not find any. Does anyone have a link to definition of DISTINCT() in mysql or knows about other authoritative source on this? Best EDIT After asking the same question on mysql forums I learned that while parsing the SQL mysql does not care about whitespace between functions and column names (but I am still missing a reference). As it seems you can have whitespace between functions and the parenthesis SELECT LEFT (field1,1), field2... and get mysql to understand it as SELECT LEFT(field,1) Similarly SELECT DISTINCT(field1), field2... seems to get decomposed to SELECT DISTINCT (field1), field2... and then DISTINCT is taken not as some undefined (or undocumented) function, but as SELECT modifying keyword and the parenthesis around field1 are evaluated as if they were part of field expression. It would be great if someone would have a pointer to documentation where it is stated that the whitespace between functions and parenthesis is not significant or to provide links to apropriate MySQL forums, mailing lists where I could raise a question to put this into reference. EDIT I have found a reference to server option IGNORE SPACE. It states that "The IGNORE SPACE SQL mode can be used to modify how the parser treats function names that are whitespace-sensitive", later on it states that recent versions of mysql have reduced this number from 200 to 30. One of the remaining 30 is COUNT for example. With IGNORE SPACE enabled both SELECT COUNT(*) FROM mytable; SELECT COUNT (*) FROM mytable; are legal. So if this is an exception, I am left to conclude that normally functions ignore space by default. If functions ignore space by default then if the context is ambiguous, such as for the first function on a first item of the select expression, then they are not distinguishable from keywords and the error can not be thrown and MySQL must accept them as keywords. Still, my conclusions feel like they have lot of assumptions, I would still be grateful and accept any pointers to see where to follow up on this.

  • How to set a default value with Html.TextBoxFor?

    - by dcompiled
    Simple question, if you use the Html Helper from ASP.NET MVC Framework 1 it is easy to set a default value on a textbox because there is an overload Html.TextBox(string name, object value). When I tried using the Html.TextBoxFor method, my first guess was to try the following which did not work: <%: Html.TextBoxFor(x => x.Age, new { value = "0"}) %> Should I just stick with Html.TextBox(string, object) for now?

  • Recursive calls in Pentaho Data Integration

    - by davek
    Is it possible for a step or transformation in Pentaho Data Integration to call itself, passing the results of the previous call as parameters/variables? My first thought was to create a loop in a transformation, but they don't seem to be allowed...

  • Code Chess: Fibonacci Sequence

    - by SLaks
    Building upon the proven success of Code Golf, I would like to introduce Code Chess. Unlike Code Golf, which strives for concision, Code Chess will strive for cleverness. Can you create a clever or unexpected Fibonacci generator? Your code must print or return either the nth Fibonacci number or the first n Fibonacci numbers.

    Hi: I am looking for a simple Russian to English word corpus. It can be as simple as a csv that lists a russian word in the first column and the equivalent English word in the second. Any ideas where I can find such a thing? Does the NLTK toolkit have something like this? Thanks

  • Improving lossless codecs [closed]

    - by LarsOn
    Improve the name to match positively Starting just discussing the naming first ignoring tech details, lossless is a negative and double negative word for one good reason should get named more appropriate: Lossless also matches nothing. When naming like all intact or likewise matches something in a manner more physical like sounds are. Then more technically stated that a copy might contain more information than the original. Does method as such have a name, if so what do I refer to, can we name it if you please or just discuss related handling.

  • Can one instance of a WCF service pass work on to another instance where this 2nd instance would rep

    - by Matt
    Let's say I have 2 instances of the same web services. Is there a way that I can have the second instance of the web service perform a task at the behest of the first instance of the WCF service and reply directly to the original requester? I could code this and include logic in WCF-A to contact WCF-B under the right conditions and then passback the result, but returning to the requester directly from WCF-B would be easier. Also, I made a handy dandy chart.

  • Why does a user have to enter "Profile" data to enter data into other tables?

    - by Greg McNulty
    EDIT It appears the user has to enter some data for his profile, otherwise I get this error below. I guess if there is no profile data, the user can not continue to enter data in other tables by default? I do not want to make entering user profile data a requirement to use the rest of the sites functionality, how can I get around this? Currently I have been testing everything with the same user and everything has been working fine. However, when I created a new user for the very first time and tried to enter data into my custom table, I get the following error. The INSERT statement conflicted with the FOREIGN KEY constraint "FK_UserData_aspnet_Profile". The conflict occurred in database "C:\ISTATE\APP_DATA\ASPNETDB.MDF", table "dbo.aspnet_Profile", column 'UserId'. The statement has been terminated. Not sure why I am getting this error. I have the user controls set up in ASP.NET 3.5 however all I am using is my own table or at least that I am aware of. I have a custom UserData table that includes the columns: id, UserProfileID, CL, LL, SL, DateTime (id is the auto incremented int) The intent is that all users will add their data in this table and as I mentioned above it has been working fine for my original first user I created. However, when i created a new user I am getting this problem. Here is the code that updates the database. protected void Button1_Click(object sender, EventArgs e) { //connect to database MySqlConnection database = new MySqlConnection(); database.CreateConn(); //create command object Command = new SqlCommand(queryString, database.Connection); //add parameters. used to prevent sql injection Command.Parameters.Add("@UID", SqlDbType.UniqueIdentifier); Command.Parameters["@UID"].Value = Membership.GetUser().ProviderUserKey; Command.Parameters.Add("@CL", SqlDbType.Int); Command.Parameters["@CL"].Value = InCL.Text; Command.Parameters.Add("@LL", SqlDbType.Int); Command.Parameters["@LL"].Value = InLL.Text; Command.Parameters.Add("@SL", SqlDbType.Int); Command.Parameters["@SL"].Value = InSL.Text; Command.ExecuteNonQuery(); } Source Error: Line 84: Command.ExecuteNonQuery();
