  • Modifying text files and executing programs with command line parameters in c# or c++ on Linux

    - by Robert Harvey
    I have a need to create a utility in Suze Linux. The utility will make modifications to some text files, and then use the information in those text files to program a device in the computer using a different executable which accepts command line parameters. I am fluent in c#, but have never worked with Linux. Should I take the time to learn Gnu C++ to do this, or install Mono? How would I execute the programming utility and pass it command line parameters?

  • Django: Localization Issue

    - by Eric
    In my application, I have a dictionary of phrases that are used throughout of the application. This same dictionary is used to create PDFs and Excel Spreadsheets. The dictionary looks like so: GLOBAL_MRD_VOCAB = { 'fiscal_year': _('Fiscal Year'), 'region': _('Region / Focal Area'), 'prepared_by': _('Preparer Name'), 'review_cycle':_('Review Period'), ... snip ... } In the code to produce the PDF, I have: fy = dashboard_v.fiscal_year fy_label = GLOBAL_MRD_VOCAB['fiscal_year'] rg = dashboard_v.dashboard.region rg_label = GLOBAL_MRD_VOCAB['region'] rc = dashboard_v.review_cycle rc_label = GLOBAL_MRD_VOCAB['review_cycle'] pb = dashboard_v.prepared_by pb_label = GLOBAL_MRD_VOCAB['prepared_by'] Now, when the PDF is produced, in the PDF, I don't see these labels but rather, I see: <django.utils.functional.__proxy__ object at 0x10106fdd0> Can somebody help me with this? How do I get the properly translated labels? Thanks Eric

I was select (Account ,Commission,Broker ,Stock) as a primary key ???

  • Ambiguous Evaluation of Lambda Expression on Array

    - by Joe
    I would like to use a lambda that adds one to x if x is equal to zero. I have tried the following expressions: t = map(lambda x: x+1 if x==0 else x, numpy.array) t = map(lambda x: x==0 and x+1 or x, numpy.array) t = numpy.apply_along_axis(lambda x: x+1 if x==0 else x, 0, numpy.array) Each of these expressions returns the following error: ValueError: The truth value of an array with more than one element is ambiguous. Use a.any() or a.all() My understanding of map() and numpy.apply_along_axis() was that it would take some function and apply it to each value of an array. From the error it seems that the the lambda is being evaluated as x=array, not some value in array. What am I doing wrong? I know that I could write a function to accomplish this but I want to become more familiar with the functional programming aspects of python.

    I have an ASP.NET page in which there is a textbox. The user enters a string in the textbox and I want that string to be searched in Google and redirect the search results to my web page.

  • Use 'let' in 'if' expression

    - by demas
    I need a function that works like this: foo :: Integer -> Integer -> [Integer] foo a b = do let result = [] let Coord x y = boo a b if x > 0 let result = result ++ [3] if y > 0 let result = result ++ [5] if x < a let result = result ++ [7] if y < b let result = result ++ [9] result I can not use the guards because the result can have more then one element. But as I see I can not use 'let' in the 'if' expression: all_possible_combinations.hs:41:14: parse error on input `let' How can I check multiple expressions and add new elements in the list? I search not only imperative solution, but the functional one.

  • A Beginners' Guide to Learning JavaScript?

    - by CloseDiamond
    There's a few mentions of Javascript newbies getting starting by checking out some of Douglas Crockford's work (http://stackoverflow.com/questions/11246/best-resources-to-learn-javascript), but none of his resources seem to be for those looking to learn from the ground up. Are there any suggestions for complete beginners regarding how best to learn JavaScript? Personally I have plenty of HTML and CSS experience, and some PHP (which would help learning JS), but for those that don't know any programming language what would you recommend?

  • Engineering techniques to diminish MVVM Driven Development time?

    - by Oscar Cabrero
    Hi Currently we just start releasing modules for a big project in MVVM but seems like the deliverables are starting to encounter a slowness with this model, such things as the learning curve effort and the fact that mvvm do requires a bit more code than other patterns, What Programming and software engineering techniques do you employ or thing could help us reduce the effort and speed up development? things like code generation with T4 templates, ligth MVVM frameworks, use Expression Blend, hire a designer to hanle UX. Thanks for any advice you could provide.

  • Apply function to one element of a list in Python

    - by user189637
    I'm looking for a concise and functional style way to apply a function to one element of a tuple and return the new tuple, in Python. For example, for the following input: inp = ("hello", "my", "friend") I would like to be able to get the following output: out = ("hello", "MY", "friend") I came up with two solutions which I'm not satisfied with. One uses a higher-order function. def apply_at(arr, func, i): return arr[0:i] + [func(arr[i])] + arr[i+1:] apply_at(inp, lambda x: x.upper(), 1) One uses list comprehensions (this one assumes the length of the tuple is known). [(a,b.upper(),c) for a,b,c in [inp]][0] Is there a better way? Thanks!

  • Real world examples of Rx

    - by theburningmonk
    I've been playing around with the Reactive Extension for a little while now, but mostly limited to handling/composing user driven events within a WPF frontend. It's such a powerful, new way of doing async programming, and I'm curious as to what other people are doing with it, and where do you think it might be able to improve the way we're currently doing things?

  • UV-vis detector [Hardware]

    - by aaa
    hello. This is not hundred percent programming related question, but I was not able to find answer on the net. Is there some kind of detector to record frequency/intensity of light radiation source? something like spectroscopy detector, but instead of actual machine, just the module which can be integrated in project. I have tried searching on Google but I do not even know what such device is called if you know the more appropriate place to ask, can you let me know please. Thank you
