• Issue with plotting daily data using ggplot

  - by user1723765

  I tried to plot daily data from 9 variables in ggplot, but the graph I get cannot handle the date variable properly. The x axis is unreadable and its impossible to read the plot. I'm guessing there's an issue with the handling of dates. Here's the data: https://dl.dropbox.com/u/22681355/su.csv Here's the code I've been using: su=read.csv(file="su.csv", head=TRUE) meltdf=melt(su) ggplot(meltdf, aes(x=Date, y=value, colour=variable, group=variable))+geom_line() and here's the output: https://dl.dropbox.com/u/22681355/output.jpg here's the same plot done in excel, why does it look completely different?

Here is my code: DateTime startDate = new DateTime(Int32.Parse(year), 1, 1); DateTime endDate = new DateTime(Int32.Parse(year), 12, 31); SPQuery q = new SPQuery(); q.Query = "<Query><Where><And><Geq><FieldRef Name='Publicate Date' /><Value IncludeTimeValue='FALSE' Type='DateTime'>" + SPUtility.CreateISO8601DateTimeFromSystemDateTime(startDate) + "</Value></Geq><Leq><FieldRef Name='Publicate_x0020_Date' /><Value IncludeTimeValue='FALSE' Type='DateTime'>" + SPUtility.CreateISO8601DateTimeFromSystemDateTime(endDate) + "</Value></Leq></And></Where></Query>"; SPListItemCollection allItem = library.GetItems(q);

• php search and replace

  - by Dave

  I am trying to create a database field merge into a document (rtf) using php i.e if I have a document that starts Dear Sir, Customer Name: [customer_name], Date of order: [order_date] After retrieving the appropriate database record I can use a simple search and replace to insert the database field into the right place. So far so good. I would however like to have a little more control over the data before it is replaced. For example I may wish to Title Case it, or convert a delimited string into a list with carriage returns. I would therefore like to be able to add extra formatting commands to the field to be replaced. e.g. Dear Sir, Customer Name: [customer_name, TC], Date of order: [order_date, Y/M/D] There may be more than one formatting command per field. Is there a way that I can now search for these strings? The format of the strings is not set in stone, so if I have to change the format then I can. Any suggestions appreciated.

• log4net one file per run

  - by Diego Mijelshon

  I need my application to create a log file each time it runs. My preferred format would be App.log.yyyy-MM-dd_HH-mm-ss. If that's not possible, I'd settle for App.log.yyyy-MM-dd.counter This is my current appender configuration: <appender name="File" type="log4net.Appender.RollingFileAppender"> <file value="App.log"/> <rollingStyle value="Date"/> <datePattern value=".yyyy-MM-dd_HH-mm-ss"/> <staticLogFileName value="false"/> <lockingModel type="log4net.Appender.FileAppender+MinimalLock" /> </appender> But it creates a random number of files based on the date and time.

• UIViewController is popped from view stack and NSURLConnection crashes the application

  - by rickharrison

  I am pushing a UIViewController onto a UINavigationController. This view controller immediately starts a download of an xml feed and then parses it. However, if you hit the back button before it is done downloading, and crashes with EXC_BAD_ACCESS. The line that is crashing it is in parserDidEndDocument and is this line: if (self.delegate && [self.delegate conformsToProtocol:@protocol(ModelDelegate)]) [self.delegate modelDidFinishParsing:self]; I assume it is crashing because it is trying to access self.delegate which is not assigned anymore. How do I get around this? Also, I would release the model object in the modelDidFinishParsing method. How would I release this model if it never reaches this method.

• How to customize Json serialization using Scala and Play Framework?

  - by Jonas

  I would like to serialize some Scala case classes to Json. E.g my case class looks like: case class Item ( id: Int, name: String, price: BigDecimal, created: java.util.Date) and I would like to serialize it to Json like this: {"id":3, "name": "apple", "price": 8.00, "created": 123424434} so I need a custom serilization for BigDecimal and for Date. Where I want the data in milliseconds since 1 jan 1970. When using Scala and Play Framework, I can return Json using Json(myObject), but how do I customize the serialization? Or is there any recommended Scala library?

• I need to debug my BrowserHelperObject (BHO) (in C++ with Visual Studio 2008) after a internet explo

  - by BHOdevelopper

  Hi, here is the situation, i'm developping a Browser Helper Object (BHO) in C++ with Visual Studio 2008, and i learned that the memory wasn't managed the same way in Debug mode than in Release mode. So when i run my BHO in debug mode, internet explorer 8 works just fine and i got no erros at all, the browser stays alive forever, but as soon as i compile it in release mode, i got no errors, no message, nothing, but after 5 minutes i can see through the task manager that internet explorer instances are just eating memory and then the browser just stop responding every time. Please, I really need some hint on how to get a feedback on what could be the error. I heard that, often it was happening because of memory mismanagement. I need a software that just grab a memory dump or something when iexplorer crashes to help me find the problem. Any help is appreciated, I'll be looking for responses every single days, thank you.

• NSURLConnection shown as leaking in instruments

  - by Gyozo Kudor

  Hello another stupid question regarding leaks and also NSURLConnection. How do i release it? Is it enough if i release in the following 2 methods? (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error (void)connectionDidFinishLoading:(NSURLConnection *)connection Because in instruments it shows me the line where I alloc my connection as the source of leaking. OK I don't get it. After the following code my urlConnection has a retain count of 2. WTF? NSURLConnection *urlConnection = [[NSURLConnection alloc] initWithRequest: urlRequest delegate: self]; This is the line that instruments points me to. I find this very weird.

• Weirdest occurrence ever, UIButton @selector detecting right button, doing wrong 'else_if'?

  - by Scott

  So I dynamically create 3 UIButtons (for now), with this loop: NSMutableArray *sites = [[NSMutableArray alloc] init]; NSString *one = @"Constution Center"; NSString *two = @"Franklin Court"; NSString *three = @"Presidents House"; [sites addObject: one]; [one release]; [sites addObject: two]; [two release]; [sites addObject: three]; [three release]; NSString *element; int j = 0; for (element in sites) { UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom]; //setframe (where on screen) //separation is 15px past the width (45-30) button.frame = CGRectMake(a, b + (j*45), c, d); [button setTitle:element forState:UIControlStateNormal]; button.backgroundColor = [SiteOneController myColor1]; [button addTarget:self action:@selector(showCCView:) forControlEvents:UIControlEventTouchUpInside]; [button setTag:j]; [self.view addSubview: button]; j++; } The @Selector method is here: - (void) showCCView:(id) sender { UIButton *button = (UIButton *)sender; int whichButton = button.tag; NSString* myNewString = [NSString stringWithFormat:@"%d", whichButton]; self.view = [[UIView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]]; self.view.backgroundColor = [UIColor whiteColor]; UINavigationBar *cc = [SiteOneController myNavBar1:@"Constitution Center Content"]; UINavigationBar *fc = [SiteOneController myNavBar1:@"Franklin Court Content"]; UINavigationBar *ph = [SiteOneController myNavBar1:@"Presidents House Content"]; if (whichButton = 0) { NSLog(myNewString); [self.view addSubview:cc]; } else if (whichButton = 1) { NSLog(myNewString); [self.view addSubview:fc]; } else if (whichButton = 2) { NSLog(myNewString); [self.view addSubview:ph]; } } Now, it is printing the correct button tag to NSLog, as shown in the method, however EVERY SINGLE BUTTON is displaying a navigation bar with "Franklin Court" as the title, EVERY SINGLE ONE, even though when I click button 0, it says "Button 0 clicked" in the console, but still performs the else if (whichButton = 1) code. Am I missing something here?

• MYSQL - multiple count statments

  - by darudude

  I'm trying to do a lookup on our demographioc table to display some stats. However, since out demographic table is quit big I want to do it in one query. There are 2 fields that are important: sex, last_login I want to be able to get the total number of logins for various date ranges (<1day ago, 1-7 days ago, 7-30 days ago, etc) GROUPED BY sex I right now know how to do it for one date range. For example less than 1 day ago: SELECT sex, count(*) peeps FROM player_account_demo WHERE last_demo_update>1275868800 GROUP BY sex Which returns: sex peeps UNKNOWN 22 MALE 43 FEMALE 86 However I'd have to do this once for each range. Is there a way to get all 3 ranges in there? I'd want my end result to look something like this: sex peeps<1day peeps1-7days peeps7-30days Thanks!

• Oracle data provider hangs IIS worker process when web site is stopped

  - by Greg

  We're experiencing a nasty issue in Oracle 11g Release 2 where the w3wp process takes over and entire processor core, and debugging shows that the Oracle data provider is throwing ThreadAbortExceptions infinitely. A developer found this issue by doing the following: 1) Browse a web site that uses Oracle data connections locally (http://localhost/OracleWebSite) - we use IIS, not the ASP.NET dev server, for all of our sites. This ensures that the w3wp process is running and that an active Oracle pool of connections exists in the app pool. 2) Stop the web site (or perform a Rebuild All operation in Visual Studio on the web site in question). Our Oracle connection handling in the affected applications (all Oracle web apps) is well-established and robust. This issue does not occur if we disable connection pooling. This issue does not occur in Oracle 11g Release 1.

• Comparing two ISO8601 dates strings in PHP

  - by oompahloompah

  I need to compare (actually rank/sort) dates in a PHP script. The dates are ISO-8601 Date format i.e. YYYY-MM-DD I wrote a comparison function which splits the dates and compares by year/month/day. However, it seems this may be overkill and I could just as easily done a simple string comparison like: if ($date1 < $date2) // do something elseif( $date1 > $date2) //do something else else //do yet another thing Is my assumption about (ISO-8601) Date string comparison correct - i.e. can I get rid of my function (to save a few clock cycles on the server), or is it safer to explicity do the comparison in a custom function?

• Subversion version 'difference' a big deal?

  - by CmdrTallen

  Greetings, using VS2008 and VisualSVN and seems the VisualSVN folks are religious about updating the client (and their VisualSVN server) to the latest Subversion release. My question is my subversion server is a hosted server and seems to always lag several versions behind the client I use. Should I be concerned about this version "mis-match"? Is there a general rule of thumb about when it is a point to be concerned (like an entire major release behind)? Any sort of mechanism build into either the client, the server or the protocol that prevents something horrible from happening between badly 'paired' clients and servers?

• Would this prevent the row from being read during the transaction?

  - by acidzombie24

  I remember an example where reads in a transaction then writing back the data is not safe because another transaction may read/write to it in the time between. So i would like to check the date and prevent the row from being modified or read until my transaction is finish. Would this do the trick? and are there any sql variants that this will not work on? update tbl set id=id where date>expire_date and id=@id Note: dateexpire_date happens to be my condition. It could be anything. Would this prevent other transaction from reading the row until i commit or rollback?

• How can I plot a time series graph with Perl?

  - by Jazz

  I have some data from a database (SQLite), mapping a value (an integer) to a date. A date is a string with this format: YYYY-MM-DD hh:mm. The dates are not uniformly distributed. I want do draw a line graph with the dates on X and the values on Y. What is the easiest way to do this with Perl? I tried DBIx::Chart but I could not make it recognize my dates. I also tried GD::Graph, but as the documentation says: GD::Graph does not support numerical x axis the way it should. Data for X axes should be equally spaced

• Django complex queries

  - by Josh K

  I need to craft a filter for an object that checks date ranges. Right now I'm performing a very inefficient loop which checks all the objects. I would like to simplify this to a database call. The logic is you have a start and an end date objects. I need to check if the start OR the end is within the range of an appointment. if (start >= appointment.start && start < appointment.end) || (end > appointment.start && end <= appointment.end) I could do this in SQL, but I'm not as familiar with the Django model structure for more complex queries.
