• how to integrate Zend Framework MVC with existing site

  - by Joel

  Hi guys, So I'm slowly tackling OO and Zend Framework and their MVC process in particular. I have an existing website and web-based calendar application that was designed by me, but coded by a different person and done procedurally. I understand that it will be very difficult for my application to ever be completely OO without a full re-write, and I'm fine with that. I have a lot of updates and modifications I want to do in the future, so I'm wanting to start replacing some of the basic components (login, authentication. etc) now, and continue to learn as I go. Again, I'm really a newbie at programming and OO. What I'm wondering is if I'm wanting to incorporate the Framework, then would I just first drop my whole site into the /public folder of the Framework and then start pulling functionality out from there?

• Explanation needed for sum of prime below n numbers

  - by Bala Krishnan

  Today I solved a problem given in Project Euler its problem no 10 and it took 7 hrs for my python program to show the result. But in that forum itself a person named lassevk posted solution for this and it took only 4 sec. And its not possible for me to post this question in that forum because its not discussion forum. So, think about this if you want to mark this question as non-constructive. marked = [0] * 2000000 value = 3 s = 2 while value < 2000000: if marked[value] == 0: s += value i = value while i < 2000000: marked[i] = 1 i += value value += 2 print s If any one understand this code please explain it simple as possible. Link to the Problem 10 question.

• Any better algorithm possible here?

  - by Cupidvogel

  I am trying to solve this problem in Python. Noting that only the first kiss requires the alternation, any kiss that is not a part of the chain due to the first kiss can very well have a hug on the 2nd next person, this is the code I have come up with. This is just a simple mathematical calculation, no looping, no iteration, nothing. But still I am getting a timed-out message. Any means to optimize it? import psyco psyco.full() testcase = int(raw_input()) for i in xrange(0,testcase): n = int(raw_input()) if n%2: m = n/2; ans = 2 + 4*(2**m-1); ans = ans%1000000007; print ans else: m = n/2 - 1 ans = 2 + 2**(n/2) + 4*(2**m-1); ans = ans%1000000007 print ans

• Is there any reason why someone would want to create an Core Data model programmatically?

  - by mystify

  I wonder in which cases it would be good to make an NSManagedObjectModel completely programmatically, with NSEntityDescription instances and all this stuff. I'm that kind of person who prefers to code programmatically, rejecting Interface Builder. But when it comes to Core Data, I have a hard time figuring out why I should kill my time NOT using the nice Xcode Data Modeler tool. And since data models are stuck to a given state (except when you want to do some ugly migration operations where thinks probably go wrong and users get mad, really mad), I see no big sense in a data model that's made programmatically for the purpose of changing it all the time. Did I miss something?

• HTML/Javascript Strange behavior with input field and TABBING

  - by Berlin Brown

  I have a strange error where if a user enters in data, say first name and then tabs, the text in the field is highlighted/selected as opposed to moving to the next. So, a person may type the first name and then tab to the next input item, text is selected and then they hit a character and now the name they typed in is deleted. If I use the default [input] tags, the tab works properly. But in the code below, with keyup, that may change the tabbing behavior. How can I get my code where it won't select the text. This is replicated in Firefox and Internet Explorer. function enableSearch(lnameObj) { var goButtonObj = document.getElementById('goButton'); var nextButtonObj = document.getElementById('nextButton'); var lastName = lnameObj.value; if (lastName == "") { goButtonObj.disabled = true; } else { goButtonObj.disabled = false; } } <input type="text" size="12" name="lastname" onKeyUp="return enableSearch(this);" value="">

• Javascript hasOwnProperty does not work under Google Chrome

  - by WebRookie

  I am currently working with some help and it has been going well, until this incident. function runCommand(commandString) { commands = new Object(); commands.clear = function(){ $('#terminal').html('') } parameters = commandString.split(" "); command = parameters.shift(); if( commands.hasOwnProperty(command)){ commandscommand; } else { $('#terminal').append(command+' command not recognized.'+''); } } The person who was helping me made this function, so I could run the "terminal-like" browsers that I needed to work on. It works fine when using Firefox, heres an example: guest@shell:/$ sudo make me sandwich sudo command not recognized. guest@shell:/$ clear *clears* guest@shell:/$ clear But under google chrome this happen: guest@shell:/$ sudo make me sandwich sudo command not recognized. guest@shell:/$ clear clear command not recognized. I believe that it has something to do with "commands.hasOwnProperty(command)" that is preventing it from working properly. I am using JQuery the javascript library to build the website, and I need to know how to solve this problem, or an alternative.

• How to modify XML on Objective-C?

  - by Vic

  Hi, I'm working on a project for the iPad, I need to read and write to an xml file, which is also used by the counter part of the application in windows. The problem that I have is that I've been looking around but I haven't found a way to modify an element or attribute in an xml, without having to build the whole xml again. I saw this other post, which is basically the same problem that I have, and I also end it up in the same point as the person asking the question, NSXMLParser and TouchXML are read only and do not allowed me to modify my xml. Any other suggestion about what can I use? Thanks!

• Verizon Fivespot firewall exceptions

  - by Patrick

  I have a Verizon Fivespot Wi-Fi router and am having issues connecting to the computer that uses it to get on the internet. I am able to connect to the Fivespot admin pages remotely and I am able to connect to the internet from the computer behind the Fivespot. I've tried asking this on superuser but have gotten nothing, I figure this is pertinent to programmers working on remote computers as well. There are two sections pertinent to this issue, Port Filtering And, Port Forwarding I've tried each individually and both together but cannot access anything through the router except for the admin page. I am trying to connect through SSH on Port 22 to an Ubuntu 10.04 box over wifi. I have called Verizon Tech Support but they were unhelpful, the person essentially read what it says on each screen without any elaboration. Any help is greatly appreciated!

• Translate GPS coordinates to location on PDF Map

  - by christo16

  Hi everyone, I'd like to know (from a high level view) what would be required to take a pdf floor plan of a building and determine where exactly you are on that floor plan using GPS coordinates? In addition to location, the user would be presented with a "turn by turn" directions to another point on the map, navigating down hallways, between cubicles, etc. Use case: an iPhone app that determined a user's location and guided them to a conference room or person's office in the building. I realize that this is by no means trivial, but any help is appreciated. Thanks!

• Custom object based on database table

  - by Archangel

  Suppose that I have a database query which looks like below - select name, gender, birthday from person where person_id = 1; When this query is executed, some records from the database are returned. I want to make a custom object which will contain the exact attributes as the column names, with the corresponding values. As an example, suppose that the object is X. So it will have three attributes which are X.name, X.gender and X.birthday, with the corresponding values from the records. Is it doable in PHP? If so, then how?

• Scala implicit dynamic casting

  - by weakwire

  I whould like to create a scala Views helper for Android Using this combination of trait and class class ScalaView(view: View) { def onClick(action: View => Any) = view.setOnClickListener(new OnClickListener { def onClick(view: View) { action(view) } }) } trait ScalaViewTrait { implicit def view2ScalaView(view: View) = new ScalaView(view) } I'm able to write onClick() like so class MainActivity extends Activity with ScalaViewTrait { //.... val textView = new TextView(this) textView.onClick(v => v.asInstanceOf[TextView] setText ("asdas")) } My concern is that i want to avoid casting v to TextView v will always be TextView if is applied to a TextView LinearLayout if applied to LinearLayout and so on. Is there any way that v gets dynamic casted to whatever view is applied? Just started with Scala and i need your help with this. UPDATE With the help of generics the above get's like this class ScalaView[T](view: View) { def onClick(action: T => Any) = view.setOnClickListener(new OnClickListener { def onClick(view: View) { action(view.asInstanceOf[T]) } }) } trait ScalaViewTrait { implicit def view2ScalaView[T](view: View) = new ScalaView[T](view) } i can write onClick like this view2ScalaView[TextView](textView) .onClick(v => v.setText("asdas")) but is obvious that i don't have any help from explicit and i moved the problem instead or removing it

How they should look like for dns query with udp protocol?

• Insert text depending on time of day and day of week.

  - by ploughansen

  I'm trying to piece together a php script to output different text depending on what day it is and the time of day. Example: On weekdays (mon-fri), I would like to output text according to the following periods of time (24H, server time, UTC): 00:00-08:00: "Lorem ipsum" 08:00-13:00: "dolor sit amet" 13:00-15:00: "Pellentesque habitant" 15:00-15:30: "dolor sit amet" 15:30-24:00: "Lorem ipsum" On weekends (sat-sun), I would like to output the following text in this time period: 00:00-24:00 "Lorem ipsum" Can anyone help with a php script to do that? I've already gotten some help over at the css-tricks forum. They supplied this code: <?php $date = strtotime("now"); $hour = date("H", $date); switch($hour) { case 00: case 01: case 02: case 03: case 04: case 05: case 06: case 07: case 08: $dets = array("img" => "image1.png", "txt" => "Lorem ipsum"); break; case 09: case 10: case 11: case 12: case 13: $dets = array("img" => "image2.png", "txt" => "dolor sit amet"); break; case 14: case 15: case 16: $dets = array("img" => "image3.png", "txt" => "Pellentesque habitant"); break; case 17: case 18: case 19: case 20: case 21: case 22: case 23: case 24: $dets = array("img" => "image1.png", "txt" => "Lorem ipsum"); break; } echo "<img src='$dets[img]' alt='$dets[txt]' />"; ?> But it works for all days, and only in full hours. I want to be able to specify per half-hour and on a day to day basis. Still a php-noob so I'm hoping someone can help me.

• Why should pop() take an argument?

  - by Stephano

  Quick background I'm a Java developer who's been playing around with C++ in my free/bored time. Preface In C++, you often see pop taking an argument by reference: void pop(Item& removed); I understand that it is nice to "fill in" the parameter with what you removed. That totally makes sense to me. This way, the person who asked to remove the top item can have a look at what was removed. However, if I were to do this in Java, I'd do something like this: Item pop() throws StackException; This way, after the pop we return either: NULL as a result, an Item, or an exception would be thrown. My C++ text book shows me the example above, but I see plenty of stack implimentations taking no arguments (stl stack for example). The Qustion How should one implement the pop function in C++? The Bonus Why?

• Converting a date string which is before 1970 into a timestamp in MySQL.

  - by Jamie

  Not a very good title, so my apologies. For some reason, (i wasn't the person who did it, i digress) we have a table structure where the field type for a date is varchar. (odd). We have some dates, such as: 1932-04-01 00:00:00 and 1929-07-04 00:00:00 I need to do a query which will convert these date strings into a unix time stamp, however, in my sql if you convert a date which is before 1970 it will return 0. Any ideas? Thanks so much! EDIT: Wrong date format. ooops.

• Comparing Page.User.Identity.Name to value in sql Table

  - by Peggy Fusselman

  First, I am SO sorry if the answer is out there. I've looked and looked and feel this is such a simple thing that it should be obvious. I'm wanting to make sure only the person who added an event can modify it. Simple! I already have a datasource that has event_added_by as a data point. It is populating a FormView. SelectCommand="SELECT * FROM [tbl_events] WHERE ([event_ID] = @event_ID)" And I have Page.User.Identity.Name. How do I compare the two? I can't pull the value from the label in the FormView so I need to find another way. if (!IsPostBack) { string uname = Page.User.Identity.Name; string owner = ""// this is where I need to grab the value from dsEvents; if (uname != owner) { //Send them somewhere saying they're not allowed to be here } } TIA for any help!

• Problem in UITableViewDelegate - RowSelected gives wrong NSIndexPath

  - by vlad259

  I have a UITableViewSource which I have subclassed. I'm overriding GetCell and using my own subclassed cells, like so: public override UITableViewCell GetCell(UITableView tableView, NSIndexPath indexPath) { MarketItem item=_tableItems[indexPath.Section].Items[indexPath.Row]; MarketCell cell=tableView.DequeueReusableCell(_cellIdentifier) as MarketCell; if (cell==null) { cell=new MarketCell(UITableViewCellStyle.Subtitle,_cellIdentifier,item); } // decorate the cell // ... return cell; } This works but when I get events in my UITableViewDelegate, the index path gets me the wrong cell (events like AccessoryButtonTapped, WillSelectRow etc). The Section and Row numbers look correct but when I do a tableView.CellAt(indexPath) I get the wrong cell. (The row and section numbers again look correct.) Things to note: The table is constantly being updated - items arrive in a different thread which are then InvokeOnMainThread'd Although the table is constantly updated, rows and sections are only added - nothing is re-ordered or deleted If I pause the updates when I get a 'WillSelectRow', it doesn't help Most interestingly (but not a shippable solution) if I make a new cell each time rather than doing DequeueReusableCell, it works correctly. I can't help thinking it's a stupid bug of my own making but can't find it. Any help would be most gratefully received!

• Google Chrome does not honor cache-policy in page header if the page is displayed in a FRAME

  - by Tim

  No matter what I do: <meta http-equiv="Cache-Control" content="no-cache" /> <meta http-equiv="Expires" content="Fri, 30 Apr 2010 11:12:01 GMT" /> <meta http-equiv="Expires" content="0" /> <HTTP-EQUIV="PRAGMA" CONTENT="NO-STORE" /> Google Chrome does not reload any page according to the page's internal cache policy if the page is displayed in a frame. It is as though the meta tags are not even there. Google Chrome seems to be ignoring these tags. Since I've gotten answers to this question on other forums where the person responding has ignored the operative condition, I will repeat it: this behavior occurs when the page is displayed in a frame. I was using the latest released version and have since upgraded to 5.0.375.29 beta but the behavior is the same in both versions. Would someone please care to confirm one way or another the behavior you are seeing with framesets and the caching/expiration policies given in meta tags? Thanks
