• Re-execute target when specified as dependency to multiple rules

  - by andrew

  I have the following GNU makefile: .PHONY a b c d a: b c b: d c: d d: echo HI I would like the target 'd' to be run twice -- since it is specified as a dependency by both b & c. Unfortunately, the target 'd' will be executed only once. The output of running make will simply be 'HI', instead of 'HI HI'. How can I fix this? Thanks! To Clarify, the goal is something like this: subdirs = a b c build: x y x: target=build x: $(subdirs) y: target=prepare y: $(subdirs) $(subdirs): $(make) -f $@/makefile $(target)

• is there a tool to see the difference between two database tables in mssql?

  - by reinier

  What is a good tool to see the differences between 2 tables (or even better, the datasets returned by 2 queries). EDIT: I'm not interested in the schema changes. Just assume that the schemas are the same. background as to why: I'm porting some legacy code which can fill a database with some pre-calced data. The easiest way to see if I got everything right, is to check the output of the old program, with the new one. I was thinking that if there is some kind of 'diff' tool for databases, this might be great.

• JQuery:FullCalendar Plugin: Events are not shown in week view and day view but are shown in month vi

  - by bocode

  I've the following code to fetch events: $('#calendar').fullCalendar({ theme: true, slotMinutes: 10, header: { left: 'prev,next today', center: 'title', right: 'month,agendaWeek,agendaDay', }, defaultView: 'agendaDay', allDaySlot: false, editable: false, events: "/cgi-bin/shlk/getshlkruns.pl" }); The output from getshlkruns.pl is fairly simple json feed: [{'title': 'Successful','start': 1266398223,'end': 1266398266,'url': '/shlk/cgi-bin/getshlkrunlog.pl?i=21'}] There are several events like above (i've removed for brevity sake). So the above events show up when am in the month view but mysteriously absent when am in week or day view. What am doing wrong here? Thanks in advance for your answers.

• How can I detect 'any' ajax request being completed using jQuery?

  - by Brian Scott

  I have a page where I can insert some javascript / jquery to manipulate the output. I don't have any other control over the page markup etc. I need to add an extra element via jquery after each present on the page. The issue is that the elements are generated via an asynchronous call on the existing page which occurs after $(document).ready is complete. Essentially, I need a way of calling my jquery after the page has loaded and the subsequent ajax calls have completed. Is there a way to detect the completion of any ajax call on the page and then call my own custom function to insert the additional elements after the newly created s ?

• Powershell equivilent of python's if __name__ == '__main__':

  - by Mark Mascolino

  I am really fond of python's capability to do things like this: if __name__ == '__main__': #setup testing code here #or setup a call a function with parameters and human format the output #etc... This is nice because I can treat a Python script file as something that can be called from the command line but it remains available for me to import its functions and classes into a separate python script file easily without triggering the default "run from the command line behavior". Does Powershell have a similar facility that I could exploit? And if it doesn't how should I be organizing my library of function files so that i can easily execute some of them while I am developing them?

• Pass logger instance to class

  - by mridang

  Hi Guys, I'm using a open-source Python library in my project. This library logs a lot of information using the logging class. ...but I can't see the output or log it to file. I know that i would have to create a logger instance and add a file-handler or a console-handler to it but how can i pass this logger instance to the class? Here's the init snippet of the class that I'm going to be using. class Periscope: ''' Main Periscope class''' def __init__(self): self.config = ConfigParser.SafeConfigParser({"lang": "en"}) if is_local: self.config_file = os.path.join(bd.xdg_config_home, "periscope", "config") if not os.path.exists(self.config_file): folder = os.path.dirname(self.config_file) if not os.path.exists(folder): logging.info("Creating folder %s" %folder) os.mkdir(folder) logging.info("Creating config file") configfile = open(self.config_file, "w") self.config.write(configfile) configfile.close() else: #Load it self.config.read(self.config_file) self.pluginNames = self.listExistingPlugins() self._preferedLanguages = None Any help? Thanks guys.

• I need to do a BASICE For Loop algorithm for a java Pyramid

  - by user1665119

  Question 2. USE THE FOR LOOP. Design and write an algorithm that will read a single positive number from the keyboard and will then print a pyramid out on the screen. The pyramid will need to be of a height equal in lines to the number inputted by the operator. Your program is not to test for negative numbers, nor is it to cater for them. For your test, use the number 7. If you would like to take the problem further, try 18 and watch what happens. Example input: 4 Example output: 1 121 12321 1234321

• How can I write a null ASCII character (nul) to a file with a Windows batch script?

  - by Matthew Murdoch

  I'm attempting to write an ASCII null character (nul) to a file from a Windows batch script without success. I initially tried using echo like this: echo <Alt+2+5+6> which seems like it should work (typing <Alt+2+5+6> in the command window does write a null character - or ^@ as it appears), but echo then outputs: More? and hangs until I press <Return>. As an alternative I tried using: copy con tmp.txt >nul <Alt+2+5+6><Ctrl+Z> which does exactly what I need, but only if I type it manually in the command window. If I run it from a batch file it hangs until I press <Ctrl+Z> but even then the output file is created but remains empty. I really want the batch file to stand alone without requiring (for example) a separate file containing a null character which can be copied when needed.

• What is the most useful R trick?

  - by Dirk Eddelbuettel

  In order to share some more tips and tricks for R, what is you single-most useful feature or trick? Clever vectorization? Data input/output? Visualization and graphics? Statistical analysis? Special functions? The interactive environment itself? One item per post, and we will see if we get a winner by means of votes. [Edit 25-Aug 2008]: So after one week, it seems that the simple str() won the poll. As I like to recommend that one myself, it is an easy answer to accept.

• How are variables bound to the body of a define_method?

  - by Chris

  While trying to brush up my Ruby skills I keep running across this case which I can't figure out an explanation for by just reading the API docs. An explanation would be greatly appreciated. Here's the example code: for name in [ :new, :create, :destroy ] define_method("test_#{name}") do puts name end end What I want/expect to happen is that the name variable will be bound to the block given to define_method and that when #test_new is called it will output "new". Instead each defined method outputs "destroy" -- the last value assigned to the name variable. What am I misunderstanding about define_method and its blocks? Thanks!

• Can anyone recommend a .Net XML Serialization library?

  - by James

  Can anyone recommend a .Net XML Serialization library (ideally open source). I am looking for a robust XML serialization library that I can throw any object at, which will produce a human readable XML representation of the public properties for logging purposes. I never need to be able to deserialize. XmlSerializer's requirement of an object having a parameter constructor is too restrictive for what I want. DataContractSerializer does not give enough control over the output (which is not particularly human-readable). Any recommendations appreciated! Thanks

• Voice Control iOS

  - by Marc Tanis

  I would like to build a simple reader app for the iPad 2 that would allow users to navigate/read via voice controls. The app would allow the user to enter a mode where the microphone was live and listened for predefined keywords like 'down', 'up', 'next', 'back', 'home', etc. I don't want to reinvent the wheel on this so I'm just wondering first, if someone has done this already and if not, are there any good tutorials or SDKs available to help with recording someone's voice, and then comparing future output to see if it matches, or just dealing with the microphone in general?

• long running process in asp.net C#

  - by user339323

  Hello All, I have a web application that has a long running (resource intensive) process in the code behind and the end output is a pdf file (images to pdf conversion tool) It runs fine..and since I am on a dedicated server, it is not at all a problem with respect to resources right now. However, I wonder that the system would reach its resource limits if, there are more than 20 users processing at a time. I have seen services online where the user enters their email and the processes are, I suppose, queued in the background and the results emailed with the 1st in 1st out method. Can someone please give me a start on how to implement this kind of logic in asp.net applications using C#? Thanks a lot in advance, Prasad.

• How do I convert a NSString into TIS-620 encoded string

  - by MacPC

  In the apple document, I can see that there's a way to convert from UTF8 string to ASCII string like this NSData *asciiData = [theString dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES]; NSString *asciiString = [[NSString alloc] initWithData:asciiData encoding:NSASCIIStringEncoding]; But my app requires a TIS-620 string to post to a site so I try to do the same thing NSData *asciiData = [newPost.header dataUsingEncoding:kCFStringEncodingMacThai allowLossyConversion:YES]; NSString *asciiString = [[NSString alloc] initWithData:asciiData encoding:kCFStringEncodingMacThai]; NSLog(@"%@", asciiString); The output I got is like this ???????????. Does anyone know how to convert the NSString to TIS-620 properly? Thanks so much.
