• Exchange 2010, multiple accepted domains, UCC and outside webhosts

  - by westbadger

  We have an Exchange 2010 server configured to send and receive mail on several accepted domains for Outlook Anywhere, with a UCC cert addressing each mail.domain.com and autodiscover.domain.com, mail.otherplace.com etc. This worked fine until an SSL domain validation cert for one of the additional domains - where the www.otherplace.com is hosted outside our org - expired. Now Exchange users in mail.otherplace.com get an expired cert warning for otherplace.com when connecting to our mail.domain.com portal. They still get mail, but with a repeated popup in Outlook 2007 and 2010. If I understand it correctly - Outlook autodiscover connects by first polling otherplace.com/autodiscover - which is the outside www server with the expired cert before continuing on to autodiscover.otherplace.com - which is where the MX record points to our in-house Exchange UCC. I'm trying to find out if we should: 1) turn down all mail functions on the outside webserver 2) delete the expired (useless for an informational site) cert on the outside webserver 3) renew the cert for otherplace.com on the outside webserver - or something completely different? Many thanks in advance for your thoughts.

• Drupal CCK field type with complex fAPI child fields

  - by Cliff Smith

  This question is basically a follow-up to this one: http://stackoverflow.com/questions/1640534/drupal-custom-cck-field-with-multiple-child-fields I need to build a CCK field type that stores several pieces of data, and fAPI form elements to accept the input for each piece of data already exist. These elements are built out into multiple HTML form inputs with fAPI #process functions. The problem is that when I try to use these elements in my CCK field, the input from the widget doesn't line up with the database columns specified in hook_field_settings(). The widget returns something like this: Array ( [thumbnail_image] => [imceimage_path] => ... [imceimage_alt] => ... [imceimage_width] => ... [imceimage_height] => ... [user_address] => [address_number] => ... [address_street] => ... [address_city] => ... [address_state] => ... Unless there's a way to specify "sub-columns" in hook_field_settings(), it appears to me that I can't use form element types with sub-elements in CCK fields. I've tried using CCK field validation to pull out the "imce_xxx" values from thumbnail_image and likewise with user_address, but that doesn't get me anywhere. Is it not possible to use form elements with child elements in CCK field definitions? Thanks, Cliff Smith

• My AJAX is only firing once,

  - by sea_1987

  Hi There, I ahave some ajax that is fired when a checkbox is clicked, it essentially sends a query string to a PHP script and then returns the relevant HTML, however, if I select a select it works fine if I then slect another checkbox as well as the previous I get no activity what so ever, not even any errors in firebug, it is very curious, does anyone have any ideas? //Location AJAX //var dataObject = new Object(); var selected = new Array(); //alert(selected); $('#areas input.radio').change(function(){ // will trigger when the checked status changes var checked = $(this).attr("checked"); // will return "checked" or false I think. // Do whatever request you like with the checked status if(checked == true) { //selected.join('&'); selected = $('input:checked').map(function() { return $(this).attr('name')+"="+$(this).val(); }).get(); getQuery = selected.join('&')+"&location_submit=Next"; alert(getQuery); $.ajax({ type:"POST", url:"/search/location", data: getQuery, success:function(data){ //alert(getQuery); //console.log(data); $('body.secEmp').html(data); } }); } else { //do something to remove the content here alert($(this).attr('name')); } });

• ASP.NET MVC Ajax.BeginForm eats params of submit button clicked. Looks like bug.

  - by RonnBlack

  If you are using Ajax.BeginForm() with multiple submit buttons similar to this: // View.aspx <% using (Ajax.BeginForm("Action", "Controller", new AjaxOptions { UpdateTargetId = "MyControl", })) { %> <span id="MyControl"> <% Html.RenderPartial("MyControl"); %> </span> <% } %> //MyControl.ascx <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl" %> <input name="prev" type="submit" value="prev" /> <input name="next" type="submit" value="next" /> //... Everything is submitted to the controller fine but the params for the submit button that was clicked are absent from the Request. In otherwords Request["next"] and Request["prev"] are always null. I looked in to the JavaScript in Microsoft.MvcAjax.js and it looks like the function Sys_Mvc_MvcHelpers$_serializeForm completely skips over the inputs that are of type 'submit'. This doesn't seem logical at all. How else can you find out what button has been clicked? It looks like a bug to me. Is there any logical reason to skip these form parameters?

• SQLAlchemy session management in long-running process

  - by codeape

  Scenario: A .NET-based application server (Wonderware IAS/System Platform) hosts automation objects that communicate with various equipment on the factory floor. CPython is hosted inside this application server (using Python for .NET). The automation objects have scripting functionality built-in (using a custom, .NET-based language). These scripts call Python functions. The Python functions are part of a system to track Work-In-Progress on the factory floor. The purpose of the system is to track the produced widgets along the process, ensure that the widgets go through the process in the correct order, and check that certain conditions are met along the process. The widget production history and widget state is stored in a relational database, this is where SQLAlchemy plays its part. For example, when a widget passes a scanner, the automation software triggers the following script (written in the application server's custom scripting language): ' wiget_id and scanner_id provided by automation object ' ExecFunction() takes care of calling a CPython function retval = ExecFunction("WidgetScanned", widget_id, scanner_id); ' if the python function raises an Exception, ErrorOccured will be true ' in this case, any errors should cause the production line to stop. if (retval.ErrorOccured) then ProductionLine.Running = False; InformationBoard.DisplayText = "ERROR: " + retval.Exception.Message; InformationBoard.SoundAlarm = True end if; The script calls the WidgetScanned python function: # pywip/functions.py from pywip.database import session from pywip.model import Widget, WidgetHistoryItem from pywip import validation, StatusMessage from datetime import datetime def WidgetScanned(widget_id, scanner_id): widget = session.query(Widget).get(widget_id) validation.validate_widget_passed_scanner(widget, scanner) # raises exception on error widget.history.append(WidgetHistoryItem(timestamp=datetime.now(), action=u"SCANNED", scanner_id=scanner_id)) widget.last_scanner = scanner_id widget.last_update = datetime.now() return StatusMessage("OK") # ... there are a dozen similar functions My question is: How do I best manage SQLAlchemy sessions in this scenario? The application server is a long-running process, typically running months between restarts. The application server is single-threaded. Currently, I do it the following way: I apply a decorator to the functions I make avaliable to the application server: # pywip/iasfunctions.py from pywip import functions def ias_session_handling(func): def _ias_session_handling(*args, **kwargs): try: retval = func(*args, **kwargs) session.commit() return retval except: session.rollback() raise return _ias_session_handling # ... actually I populate this module with decorated versions of all the functions in pywip.functions dynamically WidgetScanned = ias_session_handling(functions.WidgetScanned) Question: Is the decorator above suitable for handling sessions in a long-running process? Should I call session.remove()? The SQLAlchemy session object is a scoped session: # pywip/database.py from sqlalchemy.orm import scoped_session, sessionmaker session = scoped_session(sessionmaker()) I want to keep the session management out of the basic functions. For two reasons: There is another family of functions, sequence functions. The sequence functions call several of the basic functions. One sequence function should equal one database transaction. I need to be able to use the library from other environments. a) From a TurboGears web application. In that case, session management is done by TurboGears. b) From an IPython shell. In that case, commit/rollback will be explicit. (I am truly sorry for the long question. But I felt I needed to explain the scenario. Perhaps not necessary?)

• How to simulate slow internet connection

  - by V-Light

  I currently deploy with GAE (google app engine) and I try to implement some AJAX validation. So I got a couple text-fields and "spinners" (ajax loaders) which should be displayed when an AJAX request is sent. But I deploy on my local computer (localhost), so the GAE SDK reacts very fast on any request. It takes about 50-70 ms(miliseconds) to perform the whole ajax request, which is far far away from the real. Is there a way to somehow simulate slow Internet connection? I just want to see how my "spinners" work. I want to test some ajax setting (jquery) about timeouts, errors and so on... Any ideas ?

• Parsing unicode XML with Python SAX on App Engine

  - by Derek Dahmer

  I'm using xml.sax with unicode strings of XML as input, originally entered in from a web form. On my local machine (python 2.5, using the default xmlreader expat, running through app engine), it works fine. However, the exact same code and input strings on production app engine servers fail with "not well-formed". For example, it happens with the code below: from xml import sax class MyHandler(sax.ContentHandler): pass handler = MyHandler() # Both of these unicode strings return 'not well-formed' # on app engine, but work locally xml.parseString(u"<a>b</a>",handler) xml.parseString(u"<!DOCTYPE a[<!ELEMENT a (#PCDATA)> ]><a>b</a>",handler) # Both of these work, but output unicode xml.parseString("<a>b</a>",handler) xml.parseString("<!DOCTYPE a[<!ELEMENT a (#PCDATA)> ]><a>b</a>",handler) resulting in the error: File "<string>", line 1, in <module> File "/base/python_dist/lib/python2.5/xml/sax/__init__.py", line 49, in parseString parser.parse(inpsrc) File "/base/python_dist/lib/python2.5/xml/sax/expatreader.py", line 107, in parse xmlreader.IncrementalParser.parse(self, source) File "/base/python_dist/lib/python2.5/xml/sax/xmlreader.py", line 123, in parse self.feed(buffer) File "/base/python_dist/lib/python2.5/xml/sax/expatreader.py", line 211, in feed self._err_handler.fatalError(exc) File "/base/python_dist/lib/python2.5/xml/sax/handler.py", line 38, in fatalError raise exception SAXParseException: <unknown>:1:1: not well-formed (invalid token) Any reason why app engine's parser, which also uses python2.5 and expat, would fail when inputting unicode?

• How to let the user choose between typing price inclusive VAT or exclusive VAT in TextField?

  - by Sanoj

  I am implementing an back-office application where the user type in prices for products. Sometimes it is preferred to type the price inclusive value-added-tax, VAT and sometimes exclusive VAT. How do I best let the user choose between the inclusive or exclusive VAT in a usability perspective? I could have two TextFields above eachother one inclusive VAT and one exclusive, and reflect the input. But I don't think that reflecting the input in another TextField at realtime is good when it comes to usability, it distracts the user. I could also have two Radiobuttons above the TextField or below, or maybe besides the TextField that let the user make the choice. Or should I have a single button for turning between inclusive/exclusive VAT? like On/Off-buttons. But what text should I have on the button and how should the button be designed? I think this is good because it takes less space and it is easy to have it close to the TextField, but it's very hard to design a good button in a usability perspective. Please give me some recommendations. Maybe someone of you works with usability or have seen a similar problem.

• jQuery AJAX call not working in Webkit

  - by Brian

  I've run into a strange issue with Webkit based browsers (both Safari and Chrome - I'm testing on a Mac) and I am not sure what is causing it. Here's a small script I've created that replicates the issue: <html> <head> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script> <script type="text/javascript" language="javascript"> function doRequest() { document.test.submit(); $.ajax({ type: "GET", cache: false, url: 'ajax.php?tmp=1', success: doSuccess }); } function doSuccess(t_data,t_status,req) { alert('Data is: '+ t_data +', XMLHTTPRequest status is: '+ req.status); } </script> </head> <body> <form name="test" method="post" action="ajax.html" enctype="multipart/form-data"> <input type="file" name="file_1"> <br><input type="button" value="upload" onclick="doRequest();"> </form> </body> </html> ajax.php is: <?php echo $_REQUEST['tmp']; ?> This works as is on Firefox, but the XMLHTTPRequest status is always "0" on both Safari and Chrome. If I remove this line: document.test.submit(); then it works, but of course the form is not submitted. I've tried changing the form submit button from "button" to "submit", but that also prevents it from working on Safari or Chrome. What I am trying to accomplish is: submit the form call another script to get status on the file being uploaded via the form (it's for a small upload progress meter). Any help is really appreciated - I'm hopeful it is just a quirk I'm not familiar with. Thanks! Brian

• Why is PHP not allowing comparison?

  - by dcp3450

  I'm using PHP to read if an entry in my table on the database is set to "yes" or "no" and auto check the radio button that corresponds: <?php include 'file.php'; $query = "SELECT * FROM TABLE"; $runquery = odbc_exec($connect,$query); $status= odbc_result($runquery,"status"); odbc_close($file); ?> <form> <div class="formContainer"> <fieldset> <legend>Campus Alert<span class="tooltip">Turn campus alert on and off.</span></legend> <?php echo $status; ?> Yes <input type="radio" name="alertStatus" id="alertStatus" value="yes" <?php if($status== "yes") echo "checked";?>> No <input type="radio" name="alertStatus" id="alertStatus" value="no" <?php if($status== "no") echo "checked";?>> </fieldset> </div> the is for debugging so I can make sure what the database says and the form's reaction is correct. It prints "yes" (no quotes). However, the if statement will not respond. Any idea why it's doing this?

• Add autoFill capabilities to jQuery-UI 1.8.1

  here's what I currently have, unfortunately I cannot seem to figure out how to get autoFill to work with jQuery-UI...

Does anyone know how to extract the ID out of the autocomplete when you don't actually select the field?

• Using jQuery, setting Draggable on an element prevents blur from firing when you click the draggable

  - by Danno

  Using jQuery, when you set a blur event on a text box and set another element as draggable, when you click the draggable element, the blur event does not fire in FireFox. IE is a little better, you get the blur event but you don't get the click event on the draggable element. If you don't specify the cancel: "" in the draggable constructor, you will get the blur event to fire, but then the element you want to drag is not draggable. jQuery v1.3.2 jQuery UI v1.7.2 The console.log lines are for FireFox's FireBug plugin. <HTML> <HEAD> <TITLE>Blur/Click Workbench</TITLE> <script src="js/jquery.js" type="text/javascript" ></script> <script src="js/ui/ui.core.js" type="text/javascript"></script> <script src="js/ui/ui.draggable.js" type="text/javascript"></script> <script type="text/javascript"> function blurring() { console.log('1 - blurring - ' + $( this ).attr('id')); } function clicking() { console.log('2 - clicking - ' + $( this ).attr('id')); } $(document).ready(function() { $( ".draggableTool" ).draggable( { cancel: "" } ); $( '.property' ).blur( blurring ); $( '#labelContainer' ).click( clicking ); }); </script> </HEAD> <BODY> <input type='text' class='property' id='tb1' /> <br /> <input type='text' class='property' id='tb2' /> <br /> <label class='draggableTool' id='labelContainer' style='height:20px;position:absolute;'> <textarea id='taLabel' style='height:100%;background-color:white;border:1px solid grey;'>Label</textarea> </label> </BODY> </HTML>

• Django: Odd mark_safe behaviour?

  - by Mark

  I wrote this little function for writing out HTML tags: def html_tag(tag, content=None, close=True, attrs={}): lst = ['<',tag] for key, val in attrs.iteritems(): lst.append(' %s="%s"' % (key, escape_html(val))) if close: if content is None: lst.append(' />') else: lst.extend(['>', content, '</', tag, '>']) else: lst.append('>') return mark_safe(''.join(lst)) Which worked great, but then I read this article on efficient string concatenation (I know it doesn't really matter for this, but I wanted consistency) and decided to update my script: def html_tag(tag, body=None, close=True, attrs={}): s = StringIO() s.write('<%s'%tag) for key, val in attrs.iteritems(): s.write(' %s="%s"' % (key, escape_html(val))) if close: if body is None: s.write(' />') else: s.write('>%s</%s>' % (body, tag)) else: s.write('>') return mark_safe(s.getvalue()) But now my HTML get escaped when I try to render it from my template. Everything else is exactly the same. It works properly if I replace the last line with return mark_safe(unicode(s.getvalue())). I checked the return type of s.getvalue(). It should be a str, just like the first function, so why is this failing?? Also fails with SafeString(s.getvalue()) but succeeds with SafeUnicode(s.getvalue()). I'd also like to point out that I used return mark_safe(s.getvalue()) in a different function with no odd behavior. The "call stack" looks like this: class Input(Widget): def render(self): return html_tag('input', attrs={'type':self.itype, 'id':self.id, 'name':self.name, 'value':self.value, 'class':self.itype}) class Field: def __unicode__(self): return mark_safe(self.widget.render()) And then {{myfield}} is in the template. So it does get mark_safed'd twice, which I thought might have been the problem, but I tried removing that too..... I really have no idea what's causing this, but it's not too hard to work around, so I guess I won't fret about it.

• Why doesn't onkeydown working properly on IE?

• ifstream Open function not working

  - by Dave Swersky

  I've been all over the ifstream questions here on SO and I'm still having trouble reading a simple text file. I'm working with Visual Studio 2008. Here's my code: // CPPFileIO.cpp : Defines the entry point for the console application. // #include "stdafx.h" #include <fstream> #include <conio.h> #include <iostream> #include <string> using namespace std; int _tmain(int argc, _TCHAR* argv[]) { ifstream infile; infile.open("input.txt", ifstream::in); if (infile.is_open()) { while (infile.good()) cout << (char) infile.get(); } else { cout << "Unable to open file."; } infile.close(); _getch(); return 0; } I have confirmed that the input.txt file is in the correct "working directory" by checking the value of argv[0]. The Open method just won't work. I'm also having trouble debugging- should I not be able to set a watch on "infile.good()" or "infile.is_open()"? I keep getting "Error: member function not present." EDIT: Updated code listing with full code from .CPP file. UPDATE: The file was NOT in the Current Working Directory. This is the directory where the project file is located. Moved it there and it works when debugging in VS.NET.

• Blackberry read local properties file in project

  Hi, I have a config.properties file at the root of my blackberry project (same place as Blackberry_App_Descriptor.xml file), and I try to access the file to read and write into it. See below my class: public class Configuration { private String file; private String fileName; public Configuration(String pathToFile) { this.fileName = pathToFile; try { // Try to load the file and read it System.out.println("---------- Start to read the file"); file = readFile(fileName); System.out.println("---------- Property file:"); System.out.println(file); } catch (Exception e) { System.out.println("---------- Error reading file"); System.out.println(e.getMessage()); } } /** * Read a file and return it in a String * @param fName * @return */ private String readFile(String fName) { String properties = null; try { System.out.println("---------- Opening the file"); //to actually retrieve the resource prefix the name of the file with a "/" InputStream is = this.getClass().getResourceAsStream(fName); //we now have an input stream.

But the "name" is null because the file cannot be found... I know this is the path of the file which should be different, but I don't know what i can change... The class is in the package com.mycompany.blackberry.utils Thank you!

• Serial Communication between Java RXTX and Arduino

  - by SharpBarb

  I'm trying to communicate between my PC (Windows 7 using Netbeans and RXTX) with an Arduino Pro, using the serial port. The Arduino is actually connected to the PC using an FTDI cable. The code is based on the Java SimpleRead.Java found here. Currently the Arduino simply prints out a string when it starts up. My Java program should print the number of bytes that have been read and then print out the contents. The Java program works, sort of... If the string is long (10 bytes or so) the output will get broken up. So if on the Arduino I print Serial.println("123456789123456789"); //20 bytes including '\r' and '\n' The output of my Java program may look something like: Number of Bytes: 15 1234567891234 Number of Bytes: 5 56789 or Number of Bytes: 12 1234567891 Number of Bytes: 8 23456789 I'm thinking it's a timing problem, because when I manually go through the code using the debugger, the result string is always what it should be: one 20 byte string. I've been messing with various things but I haven't been able to fix the problem. Here is the part of the code that is giving me problems: static int baudrate = 9600, dataBits = SerialPort.DATABITS_8, stopBits = SerialPort.STOPBITS_1, parity = SerialPort.PARITY_NONE; byte[] readBuffer = new byte[128]; ... ... public void serialEvent(SerialPortEvent event) { if (event.getEventType() == SerialPortEvent.DATA_AVAILABLE) { try { if (input.available() > 0) { //Read the InputStream and return the number of bytes read numBytes = input.read(readBuffer); String result = new String(readBuffer,0,numBytes); System.out.println("Number of Bytes: " + numBytes); System.out.println(result); } } catch (IOException e) { System.out.println("Data Available Exception"); } }

• RFC regarding WAM

  Request For Comment regarding Whitespace's Assembly Mnemonics What follows in a first generation attempt at creating mnemonics for a whitespace assembly language. STACK ===== push number copy copy number swap away away number MATH ==== add sub mul div mod HEAP ==== set get FLOW ==== part label call label goto label zero label less label back exit I/O === ochr oint ichr iint In the interest of making improvements to this small and simple instruction set, this is a second attempt. hold N Push the number onto the stack copy Duplicate the top item on the stack copy N Copy the nth item on the stack (given by the argument) onto the top of the stack swap Swap the top two items on the stack drop Discard the top item on the stack drop N Slide n items off the stack, keeping the top item add Addition sub Subtraction mul Multiplication div Integer Division mod Modulo save Store load Retrieve L: Mark a location in the program call L Call a subroutine goto L Jump unconditionally to a label if=0 L Jump to a label if the top of the stack is zero if<0 L Jump to a label if the top of the stack is negative return End a subroutine and transfer control back to the caller exit End the program print chr Output the character at the top of the stack print int Output the number at the top of the stack input chr Read a character and place it in the location given by the top of the stack input int Read a number and place it in the location given by the top of the stack What do you think of the following revised list for Whitespace's assembly instructions? I'm still thinking outside of the box somewhat and trying to come up with a better mnemonic set than last time. When the previous interpreter was written, it was completed over two contiguous, rushed evenings. This rewrite deserves significantly more time now that it is the summer. Of course, the next version of Whitespace (0.4) may have its instructions revised even more, but this is just a redesign of what originally was done in a very short amount of time. Hopefully, the instructions make more sense once someone new to programmings thinks about them.

• Rails RJS template displays code instead of the html page

  - by Anand

  After having Googled and hurting my brain for hours on this, I finally decided to post this question. Here's the code... view1.html.erb -------------- <%=link_to_remote_redbox "Link", :url => {:action => :action1, :id => @some.id} some_controller.rb ------------------ def action1 render :layout => false end def action2 do some processing end action1.html.erb -------------------- <form onsubmit="new Ajax.Request('/some_controller/action2', {asynchronous:true, evalScripts:true, onComplete:function(request){RedBox.close(); return false;}, parameters:Form.serialize(this)}); return false;}" method="post" action="/some_controller/action2"> <input type=text name='username'> <input type='submit' value='submit'> </form> action2.rjs ----------- page.replace_html("some_div", (render(:partial => "some_partial"))) with that code in place when action2.rjs kicks in it should display the html page instead I am getting this Element.update("some_div", "<style type=\"text/css\">\n\n.............. As suggested on other posts I read, they say its caused because of the ":update = some_div" in the link_to_remote_redbox function but clearly my code doesn't have that. Help is always appreciated. Many Thanks

• HTML - Correct way of coding a checkbox with a Label.

  - by egarcia

  I've been using formtastic in order to generate HTML forms on rails applications. My question, however, is really HTML-related. Today I found a strange behaviour on the way formtastic generates checkboxes (fields of type :boolean on formtastic lingo). The rest of the fields (non-checkboxes) are generated this way: <li> <label for="my_textbox_field">My TextBox</label> <input id="my_textbox_field" type="text" ... > </li> Checkboxes, however, are enclosed inside their <label> tags completely - like this: <li> <label for="my_boolean_field"> <input id="my_boolean_field" type="checkbox" ... > This is my boolean field </label> </li> Formtastic phylosophy seems to be based on the Learning to Love Forms presentation. In effect, on slide 36 of that presentation this structure is suggested for checkboxes. I guess in the presentation itself the presenter explained why this was done, but it is not written on the slides. Can anyone tell me why enclosing checkboxes inside their <label> tag might be a good idea, as opposed to putting them outside, like with textboxes?

• How to Create Deterministic Guids

  - by desigeek

  In our application we are creating Xml files with an attribute that has a Guid value. This value needed to be consistent between file upgrades. So even if everything else in the file changes, the guid value for the attribute should remain the same. One obvious solution was to create a static dictionary with the filename and the Guids to be used for them. Then whenever we generate the file, we look up the dictionary for the filename and use the corresponding guid. But this is not feasible coz we might scale to 100's of files and didnt want to maintain big list of guids. So another approach was to make the Guid the same based on the path of the file. Since our file paths and application directory structure are unique, the Guid should be unique for that path. So each time we run an upgrade, the file gets the same guid based on its path. I found one cool way to generate such 'Deterministic Guids' (Thanks Elton Stoneman). It basically does this: private Guid GetDeterministicGuid(string input) { //use MD5 hash to get a 16-byte hash of the string: MD5CryptoServiceProvider provider = new MD5CryptoServiceProvider(); byte[] inputBytes = Encoding.Default.GetBytes(input); byte[] hashBytes = provider.ComputeHash(inputBytes); //generate a guid from the hash: Guid hashGuid = new Guid(hashBytes); return hashGuid; } So given a string, the Guid will always be the same. Are there any other approaches or recommended ways to doing this? What are the pros or cons of that method?
