  • Using gprof with sockets

    - by Chris
    I have a program I want to profile with gprof. The problem (seemingly) is that it uses sockets. So I get things like this: ::select(): Interrupted system call I hit this problem a while back, gave up, and moved on. But I would really like to be able to profile my code, using gprof if possible. What can I do? Is there a gprof option I'm missing? A socket option? Is gprof totally useless in the presence of these types of system calls? If so, is there a viable alternative? EDIT: Platform: Linux 2.6 (x64) GCC 4.4.1 gprof 2.19

  • Passing around a SqlConnection

    - by Chris
    I have created a TransactionScope and within the scope various items are created and updated in the database. During this process I make a lot of calls to the database. Originally I opened a SqlConnection in the beginning of the TransactionScope and passed it around to any function that made a DB call then I closed the connection after all the calls are made and before the transaction commits. Is it better to do this or to open and close a connection for each call?

  • CDN for Images in ASP.NET

    - by Chris
    I am in the process of moving all of the images in my web application over to a CDN but I want to easily be able to switch the CDN on or off without having to hard code the path to the images. My first thought was to add an HttpHandler for image extensions that depending whether a variable in the web.config (something like ) will serve the image from the server or from the CDN. But after giving this a little though I think I've essentially ruled this out as it will cause ASP.NET to handle the request for every single image, thus adding overhead, and it might actually completely mitigate the benefits of using a CDN. An alternative approach is, since all of my pages inherit from a base page class, I could create a function in the base class that determines what path to serve the files from based off the web.config variable. I would then do something like this in the markup: <img src='<%= GetImagePath()/image.png' /> I think this is probably what I'll have to end up doing, but it seems a little clunky to me. I also envision problems with the old .NET error of not being able to modify the control collection because of the "<%=" though the "<%#" solution will probably work. Any thoughts or ideas on how to implement this?

  • Ruby - Passing Blocks To Methods

    - by Chris Bunch
    I'm trying to do Ruby password input with the Highline gem and since I have the user input the password twice, I'd like to eliminate the duplication on the blocks I'm passing in. For example, a simple version of what I'm doing right now is: new_pass = ask("Enter your new password: ") { |prompt| prompt.echo = false } verify_pass = ask("Enter again to verify: ") { |prompt| prompt.echo = false } And what I'd like to change it to is something like this: foo = Proc.new { |prompt| prompt.echo = false } new_pass = ask("Enter your new password: ") foo verify_pass = ask("Enter again to verify: ") foo Which unfortunately doesn't work. What's the correct way to do this?

  • Consuming a HTTPS Web Service in .Net 3.5 Web Project

    - by Chris M
    I'm trying to consume a webservice that ONLY runs on HTTPS but using the "add service" method in VS or using the WSDL to generate a code file leaves me with a web service that states its http... <wsdl:service name="OGServ"> <wsdl:documentation xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/">XML Web Services element of OGServ Gateway</wsdl:documentation> <wsdl:port name="OGServSoap" binding="tns:OGServSoap"> <soap:address location="http://ogserv.domain.co.uk/ogwsrv/og.asmx" /> </wsdl:port> <wsdl:port name="OGServSoap12" binding="tns:OGServSoap12"> <soap12:address location="http://ogserv.domain.co.uk/ogwsrv/og.asmx" /> </wsdl:port> </wsdl:service> Would this be the reason that even when I change the app.config (generated by the add-service) endpoint address to https it says it was expecting HTTP?

  • Creating a Calender in PHP

    Are there any APIs/Libraries that make it easy to generate a calender for a certain month/year? I need to have some sort of admin interface for a "event planner" part of a CMS for a local youth group and I'm at a loss as to how to generate a decent calender.

  • How to track IIS server performance

    - by Chris Brandsma
    I have a reoccurring issue where a customer calls up and complains that the web site is too slow. Specifically, if they are inactive for a short period of time, then go back to the site, there will be a minute-two minute delay before the user sees a response. (the standard browser is Firefox in this case) I have Perfmon up and running, the cpu utilization is usually below 20% (single proc...don't ask). The database is humming along. And I'm pulling my hair out. So, what metrics/tools do you find useful when evaluating IIS performance?

  • help('modules') crashing? Not sure how to fix..

  • Stop jQuery animations stacking

    - by Chris
    I have an Options box that hovers in the top right of the webpage. It's opacity is set to 10% so as not to be obstructive to users. When they hover over (mouseenter) it I use jQuery to fade it in and slidedown the content (and the reverse on mouseout). If they do this repeatedly though the animation stacks up and you can sometimes be left in a situation where your mouse is stood still but the box is yo-yoing around. How can I get around this situation? Here is how I currently setup the animations $("#dropdown").mouseenter(function() { $(this).fadeTo('fast',1); $("#options").slideDown(); }); $("#dropdown").mouseleave(function() { $(this).fadeTo('fast',0.1); $("#options").slideUp(); }); Note I am using jQuery only and not any other plugins.

  • How to configure multiple mappings using FluentHibernate?

    - by chris.baglieri
    First time rocking it with NHibernate/Fluent so apologies in advance if this is a naive question. I have a set of Models I want to map. When I create my session factory I'm trying to do all mappings at once. I am not using auto-mapping (though I may if what I am trying to do ends up being more painful than it ought to be). The problem I am running into is that it seems only the top map is taking. Given the code snippet below and running a unit test that attempts to save 'bar', it fails and checking the logs I see NHibernate is trying to save a bar entity to the foo table. While I suspect it's my mappings it could be something else that I am simply overlooking. Code that creates the session factory (note I've also tried separate calls into .Mappings): Fluently.Configure().Database(MsSqlConfiguration.MsSql2008 .ConnectionString(c => c .Server(@"localhost\SQLEXPRESS") .Database("foo") .Username("foo") .Password("foo"))) .Mappings(m => { m.FluentMappings.AddFromAssemblyOf<FooMap>() .Conventions.Add(FluentNHibernate.Conventions.Helpers .Table.Is(x => "foos")); m.FluentMappings.AddFromAssemblyOf<BarMap>() .Conventions.Add(FluentNHibernate.Conventions.Helpers .Table.Is(x => "bars")); }) .BuildSessionFactory(); Unit test snippet: using (var session = Data.SessionHelper.SessionFactory.OpenSession()) { var bar = new Bar(); session.Save(bar); Assert.NotNull(bar.Id); }

  • What's wrong with output parameters?

    - by Chris McCall
    Both in SQL and C#, I've never really liked output parameters. I never passed parameters ByRef in VB6, either. Something about counting on side effects to get something done just bothers me. I know they're a way around not being able to return multiple results from a function, but a rowset in SQL or a complex datatype in C# and VB work just as well, and seem more self-documenting to me. Is there something wrong with my thinking, or are there resources from authoritative sources that back me up? What's your personal take on this and why? What can I say to colleagues that want to design with output parameters that might convince them to use different structures? EDIT: interesting turn- the output parameter I was asking this question about was used in place of a return value. When the return value is "ERROR", the caller is supposed to handle it as an exception. I was doing that but not pleased with the idea. A coworker wasn't informed of the need to handle this condition and as a result, a great deal of money was lost as the procedure failed silently!

  • How does Access 2007's moveNext/moveFirst/, etc., feature work?

    - by Chris M
    I'm not an Access expert, but am an SQL expert. I inherited an Access front-end referencing a SQL 2005 database that worked OK for about 5000 records, but is failing miserably for 800k records... Behind the scenes in the SQL profiler & activity manager I see some kind of Access query like: SELECT "MS1"."id" FROM "dbo"."customer" "MS1" ORDER BY "MS1"."id" The MS prefix doesn't appear in any Access code I can see. I'm suspicious of the built-in Access navigation code: DoCmd.GoToRecord , , acNext The GoToRecord has AcRecord constant, which includes things like acFirst, acLast, acNext, acPrevious and acGoTo. What does it mean in a database context to move to the "next" record? This particular table uses an identity column as the PK, so is it internally grabbing all the IDs and then moving to the one that is the next highest??? If so, how would it work if a table was comprised of three different fields for the PK? Or am I on the wrong track, and something else in Access is calling that statement? Unfortunately I see a ton of prepared statements in the profiler. THanks!

    I have a Windows CE console application that's entry point looks like this int _tmain(int argc, _TCHAR* argv[]) I want to check the contents of argv[1] for "-s" convert argv[2] into an integer. I am having trouble narrowing the arguments or accessing them to test. I initially tried the following with little success if (argv[1] == L"-s") I also tried using the narrow function of wostringstream on each character but this crashed the application. Can anyone shed some light? Thanks

  • What alternatives are there to Google App Engine?

    - by Chris Marasti-Georg
    What alternatives are there to GAE, given that I already have a good bit of code working that I would like to keep. In other words, I'm digging python. However, my use case is more of a low number of requests, higher CPU usage type use case, and I'm worried that I may not be able to stay with App Engine forever. I have heard a lot of people talking about Amazon Web Services and other sorts of cloud providers, but I am having a hard time seeing where most of these other offerings provide the range of services (data querying, user authentication, automatic scaling) that App Engine provides. What are my options here?

  • lua metatable __lt __le __eq forced boolean conversion of return value

    - by chris g.
    Overloading __eq, __lt, and __le in a metatable always converts the returning value to a boolean. Is there a way to access the actual return value? This would be used in the following little lua script to create an expression tree for an argument usage: print(_.a + _.b - _.c * _.d + _.a) -> prints "(((a+b)-(c*d))+a)" which is perfectly what I would like to have but it doesn't work for print(_.a == _.b) since the return value gets converted to a boolean ps: print should be replaced later with a function processing the expression tree -- snip from lua script -- function binop(op1,op2, event) if op1[event] then return op1[event](op1, op2) end if op2[event] then return op2[event](op1, op2) end return nil end function eq(op1, op2)return binop(op1,op2, "eq") end ... function div(op1, op2)return binop(op1,op2, "div") end function exprObj(tostr) expr = { eq = binExpr("=="), lt = binExpr("<"), le = binExpr("<="), add = binExpr("+"), sub=binExpr("-"), mul = binExpr("*"), div= binExpr("/") } setmetatable(expr, { __eq = eq, __lt = lt, __le = le, __add = add, __sub = sub, __mul = mul, __div = div, __tostring = tostr }) return expr end function binExpr(exprType) function binExprBind(lhs, rhs) return exprObj(function(op) return "(" .. tostring(lhs) .. exprType .. tostring(rhs) .. ")" end) end return binExprBind end function varExpr(obj, name) return exprObj(function() return name end) end _ = {} setmetatable(_, { __index = varExpr }) -- snap -- Modifing the lua vm IS an option, however it would be nice if I could use an official release

  • 404 on custom post types after updating Wordpress to 3.7

    - by Chris
    Since I updated Wordpress from 3.6 to 3.7, I'm not able to visit the single-pages on my custom post types, then I get a 404 error. I thought this would be a rewrite_rules issue, so I've tried the following: -Go to the Permalink settings, click save (flush rewrites) -Manually deleted the rewrite_rules from the option table in the DB (I was desparate, and it seriously worked for me one time) -Re-check my .htaccess, but this is the exactly same as instructed on the permalink page -switched off the plugins I also tried switching the permalink to the "ugly" url (eg. ?page=35) and check if the articles worked, and they did! So I'm pretty sure it's a permalink issue. Now I rolled back to 3.6 again, but I of course want to upgrade in the near future (security etc.). A remarkable thing was that during the rollback I checked out a single page (notice that I didn't rolled back the database yet, only the files) and surprisingly they worked again. Any suggestions on how to solve this?

  • Folder Renaming After Tar Extraction

    - by Chris S
    I have an tarball, myarchive.tar.gz. When I uncompress it using "tar -zxvf myarchive.tar.gz", it creates a folder myarchive-x980-2303-ssioo. What's the easiest way to automatically rename the extracted folder to ensure it matches the name of the archive? I've checked tar's manpage, but it doesn't seem to have an option for this.

  • Is there a good IDE for SQLite ?

    Is there a tool out there that can interact with a SQLite database in a similar way that TOAD works with Oracle or Management Studio works with SQL Server?

  • Objective C: App freezes when using a timer

    - by Chris
    It took me hours to figure out how to implement a timer into my program, but when it runs, the app doesn't load completely as it did before the timer. In my main.m: int main (int argc, const char * argv[]) { NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init]; OutLauncher *theLauncher = [[OutLauncher alloc] init]; NSTimer *theTimer = [theLauncher getTimer]; [theTimer retain]; [[NSRunLoop currentRunLoop] addTimer: theTimer forMode: NSDefaultRunLoopMode]; [[NSRunLoop currentRunLoop] run]; [pool release]; return 0; } The file OutLauncher is being imported into that, which looks like this: - (void)doStuff { NSLog( @"Doing Stuff"); } - (NSTimer *)getTimer{ NSTimer *theTimer; theTimer = [NSTimer scheduledTimerWithTimeInterval:1.0 target:self selector: @selector(doStuff) userInfo:nil repeats:YES]; return [theTimer autorelease]; } The timer works, the console updates every second with the phrase "doing stuff" but the rest of the program just won't load. It will if I comment out the code I added to int main though

  • Prototype: Form.serialize missing some inputs (due to table?)

    - by Chris
    I'm using JavaScript Prototype (through Ruby on Rails) to handle some Ajax calls; but in one particular case I'm missing a field from the form. I have a layout like this: +---------+---------+ | Thing 1 | Thing 2 | +---------+---------+-----------+ | o Opt 1 | o Opt 1 | <Confirm> | | o Opt 2 | o Opt 2 | | +---------+---------+-----------+ Opt 1 and 2 are Radio buttons, Confirm is a button. The entire table is wrapped in a form, with code like: <form action="javascript:void(0)"> <input type="hidden" name="context" value="foo" /> <input type="hidden" name="subcontext" value="bar" /> <table> <tr><td>Thing 1</td><td>Thing2</td></tr> <tr><td> <input type="radio" name="choice" value="1.1" />Opt 1<br /> <input type="radio" name="choice" value="1.2" />Opt 2<br /> </td><td> <input type="radio" name="choice" value="2.1" />Opt 1<br /> <input type="radio" name="choice" value="2.2" />Opt 2<br /> </td><td> <input name="choice_btn" type="button" value="Confirm" onclick="new AJAX.Updater('my_form', '/process_form', {asynchronous:true, evalScripts:true, parameters:Form.serialize(this.form)}); return false;" /> </td></tr> </table> </form> But I can see that the POST generated by clicking the Confirm button contains the foo and bar values for the hidden fields, but not the choice of the radio buttons. Is this because I've got a table inside my form? How can I get around this?
