  • MVC alternatives: examples of MVA & AVC?

    - by Phillip Oldham
    I'm interested in learning about the alternative patterns to Model-View-Controller, specifically the Model-View-Adapter and Application-View-Controller patterns. Google results tend to be either a high-level overview or Java-based. Can anyone either provide, or point me to, an example of these patterns in either PHP, Python or JavaScript?

  • How do I run an array through an IF statement in rails?

    - by codyvbrown
    I am creating an application that highlights user messages from a stream based on whether or not the user has been 'vouched'. It works fine if it's setup for a single author. For example controller: @vouch = Vouch.last.vouched_user_nickname view: <% Twitter::Search.new(params[:id]).each do |tweet| %> <li> <%= image_tag tweet.profile_image_url %> <% if @vouch.include? tweet.from_user %> <div class="flit_message_containerh"> <u> <a href="http://twitter.com/<%= tweet.from_user %>"> <%= tweet.from_user %></a></u> <%= linkup_mentions(auto_link(h tweet.text)) %> <div class="time_ago"> <%= link_to distance_of_time_in_words_to_now(tweet.created_at) , tweet %> <% else %> <div class="flit_message_container"> <u> <a href="http://twitter.com/<%= tweet.from_user %>"> <%= tweet.from_user %></a></u> <%= linkup_mentions(auto_link(h tweet.text)) %> <div class="time_ago"> <%= link_to distance_of_time_in_words_to_now(tweet.created_at) , tweet %> <% end %> But I'm having trouble doing it for multiple user nicknames. @vouch = Vouch.find(:all, :select => "vouched_user_nickname", :group => 'vouched_user_nickname' ) Any ideas would be greatly appreciated. I'm a rails noob.

  • How to generate random html document

    - by karramba
    I'd like to generate completely random piece of html source, possibly from a grammar. I want to do this in python but I'm not sure how to proceed -- is there a library that takes a grammar and just randomly follows its rules, printing the path? Ideas?

  • PHP - advice for java HashMap alternative in php?

    - by teutara
    I know it is super noob and will be answered in no time, but I could not figure.. sorry for any inconvenience.. Here is the thing: ID colA colB Length 1 seq1 seq11 1 2 seq1 seq11 11 3 seq3 seq33 21 4 seq3 seq33 14 I have a db with this kind of a table, has more than 10M rows. I want to loop though colA first, get the relevant colB value, and check if there are any other occurrences of the same value. For example in colB (seq11) there are 2 occurrences of colA(seq1), this time I have to combine those and output the sum of the length. Similar to this: ID colA colB Length 1 seq1 seq11 12 2 seq3 seq33 35 I am a bit java guy, but because my colleague has written everything in php and this will be just an adding, i need a php solution. With java i would have used hashmap, so that I would have the colA data once and just increment the value of "Length Column".. I know it is not a proper question, but.. Thank you in advance.. $$$$$$$$$$ EDIT $$$$$$$$$$ I tried this query in order to group by occurences: SELECT COUNT(*) SeqName FROM SeqTable GROUP BY SeqName HAVING COUNT(*)>0;

  • OpenSource programming-languages in development?

    - by pile of junk
    I'm very interested in interpreter and compiler development and because I don't want to continue building mini compilers and interpreters I thought I could help some open-source project. Are there currently open-source projects on compilers/interpreters in early stages seeking developers? I mean yeah.. There won't be much to do for someone like me in Python, Ruby, and so on.

  • C Language Standard Collections Where Are They?

    - by flaxeater
    I have committed to learning C now, I'm good with Python/PHP/Bash but I've decided I'm limited by not being fluent in C. However I cannot imagine working in a language without lists and hashes, maybe I'm just jumping a gun, but surely there are 'standard' collection libraries. I do not see any in the GNU standard lib though, any suggestions?

  • C: writing the following code into functions

    - by donok
    Dear respected programmers. Please could you help me (again) on how to put the following code into functions for my program. I have read on-line and understand how functions work but when I do it myself it all goes pear shaped/wrong(I am such a noob). Please could you help with how to for example to write the code below into functions.(like opening the input file). My attempt: void outputFile(int argc, char **argv) { /* Check that the output file doesnt exist */ if (stat(argv[argc-1], &inode) != -1) { printf("Warning: The file %s already exists. Not going to overwrite\n", argv[argc-1]); return -1; } /*Opening ouput files*/ file_desc_out = open(argv[i],O_CREAT | O_WRONLY | O_EXCL , S_IRUSR|S_IWUSR); if(file_desc_out == -1) { printf("Error: %s cannot be opened. \n",argv[i]); //insted of argv[2] have pointer i. return -1; } } Any help on how I would now reference to this in my program is appreciated thank you. I tried: ouputfile(but I cant figure out what goes here and why either).

  • Vim navigation clunkiness

    - by Sean Chambers
    I've committed myself to diving into vim to become faster at writing code for ruby/python and I'm having a hard time navigating around files. Mainly, I'm referring to switching between insert mode and navigation modes. Maybe I'm just not completely used to the editor yet but it feels very awkward to constantly be switching in and out of insert mode. Is this something that will go away with time? Are there any tricks to getting quicker at moving in and out of insert mode?

  • How do you send an extended-ascii AT-command (CCh) from Android bluetooth to a serial device?

    - by softex
    This one really has me banging my head. I'm sending alphanumeric data from an Android app, through the BluetoothChatService, to a serial bluetooth adaptor connected to the serial input of a radio transceiver. Everything works fine except when I try to configure the radio on-the-fly with its AT-commands. The AT+++ (enter command mode) is received OK, but the problem comes with the extended-ascii characters in the next two commands: Changing the radio destination address (which is what I'm trying to do) requires CCh 10h (plus 3 hex radio address bytes), and exiting the command mode requires CCh ATO. I know the radio can be configured OK because I've done it on an earlier prototype with the serial commands from PIC basic, and it also can be configured by entering the commands directly from hyperterm. Both these methods somehow convert that pesky CCh into a form the radio understands. I've have tried just about everything an Android noob could possibly come up with to finagle the encoding such as: private void command_address() { byte[] addrArray = {(byte) 0xCC, 16, 36, 65, 21, 13}; CharSequence addrvalues = EncodingUtils.getString(addrArray, "UTF-8"); sendMessage((String) addrvalues); } but no matter what, I can't seem to get that high-order byte (CCh/204/-52) to behave as it should. All other (< 127) bytes, command or data, transmit with no problem. Any help here would be greatly appreciated. -Dave

  • jquery an div tags used in a ordered list

    - by shan2on
    hello everyone, i'm not sure where my errors are lying but here is my scenario... i have an un-ordered list in html that handles my main link bar... <ul id="navlist"> <li><a href="/" id="current">home</a></li> <li><a href="#" id="search">search</a></li> <li><a href="#" id="users">login</a></li> </ul> and what i want done is to call each id and have jQuery handle each and dislpay it where specified in my css file... for now, lets just ignore my "home" link... here is a snippet of my inline jquery $(document).ready(function() { $("a").click(function () { $("div#login").slideToggle("fast"); }); }) Now, whichever div i specify, it calls that ... however it will only call one div, using either from the un-orderd list, as mentioned above in the html. My Goal is to call a search bar when search is clicked, and to call a login box when login is clicked. to my knowledge (noob), i believe use an as a class, however that is what brings me here. i believe my error is in my jquery and not my css, as stated above, either instance will be displayed when the jquery function calls either tag. any help is greatly appreciated. thanks in advance shan2on

  • SQL commands generated in Django by running sqlall

    - by k-g-f
    In my Django app, I just ran $ python manage.py sqlall and I see a lot of SQL statements that look like this, when describing FK relationships: ALTER TABLE `app1_model1` ADD CONSTRAINT model2_id_refs_id_728de91f FOREIGN KEY (`model2_id`) REFERENCES `app1_model2` (`id`); Where does "7218de91f" come from? I would like to know because I'd like to manually write SQL statements to accompany models changes in the app so that my db's can be kept up to date.

  • fluent nhibernate - storing and retrieving three classes in/from one table

    - by Will I Am
    Noob question. I have this situation where I have these objects: class Address { string Street; string City; ... } class User { string UserID; Address BillingAddress; Address MailingAddress; ... } What is the proper way of storing this data using (fluent) nHibernate? I could use a separate Address table and create a reference, but they are 1:1 relationships so I don't really want to incur the overhead of a join. Ideally I would store this as a single flat record. So, my question is, what is the proper way of storing an instance of class 'User' in such a way that it stores its contents and also the two addresses as a single record? My knowledge is failing me on how I can store this information in such a way that the two Address records get different column names (e.g. BillingAddress_Street and MailingAddress_Street, for example), and also how to read a record back into a User instance.

  • How to implement a search page which shows results on the same page?

    - by Andrew
    I'm using ASP.NET MVC 2 for the first time on a project at work and am feeling like a bit of a noob. I have a page with a customer search control/partial view. The control is a textbox and a button. You enter a customer id into the textbox and hit search. The page then "refreshes" and shows the customer details on the same page. In other words, the customer details appear below the customer search control. This is so that if the customer isn't the right one, the user can search again without hitting back in the browser. Or, perhaps they mistyped the customer id and need to try again. I want the URL to look like this: /Customer/Search/1 Obviously, this follows the default route in the project. Now, if I type the URL above directly into my browser, it works fine. However, when I then use the search control on that page to search for say customer 2, the page refreshes with the correct customer details but the URL does not change! It stays as /Customer/Search/1 When I want it to be /Customer/Search/2 How can I get it to change to the correct URL? I am only using the default route in Global.asax. My Search method looks like this: <AcceptVerbs(HttpVerbs.Get)> _ Function Search(ByVal id As String) As ActionResult Dim customer As Customer = New CustomerRepository().GetById(id) Return View("SearchResult", customer) End Function

  • How do call this symbolic code transformation ?

    - by erric
    Hi, I often cross this kind of code transformation (or even mathematical transformation) (python example, but applies to any language) I've go a function def f(x): return x I use it into another one. def g(x): return f(x)*f(x) print g(2) leads to 4 But I want to remove the functional dependency, and I change the function g into def g(f): return f*f print g( f(2) ) leads to 4 too How do you call this kind of transformation, locally turning a function into a scalar ?

  • How can I left-justify numerical output in fortran?

    - by mishaF
    I am writing some simple output in fortran, but I want whitespace delimiters. If use the following statement, however: format(A20,ES18.8,A12,ES18.8) I get output like this: p001t0000 3.49141273E+01obsgp_oden 1.00000000E+00 I would prefer this: p001t0000 3.49141273E+01 obsgp_oden 1.00000000E+00 I tried using negative values for width (like in Python) but no dice. So, is there a way to left-justify the numbers? Many thanks in advance!

  • Looking for a script/tool to dump a list of installed features and programs on Windows Server 2008 R

    - by Hamish Grubijan
    Hi, The same compiled .Net / C++ / Com program does different things on two seemingly same computers. Both have DOZENS of things installed on them. I would like to figure out what the difference between the two is by looking at an ASCII diff. Before that I need to "serialize" the list of installed things in a plain readable format - sorted alphabetically + one item per line. A Python script would be ideal, but I also have Perl, PowerShell installed. Thank you.
