• PHP News Feed Database & Design

  - by pws5068

  I'm designing a News Feed system using PHP/MySQL similar to facebook's. I have asked a similar question before but now I've changed the design and I'm looking for feedback. Example News: User_A commented on User_B's new album. "Hey man nice pictures!" User_B added a new Photo to [his/her] profile. [show photo thumbnail] Initially, I implemented this using excessive columns for Obj1:Type1 | Obj2:Type2 | etc.. Now the design is set up using a couple special keywords, and actor/receiver relationships. My database uses a table of messages joined on a table containing userid,actionid,receiverid,receiverObjectTypeID, Here's a condensed version of what it will look like once joined: News_ID | User_ID | Message | Timestamp 2643 A %a commented on %o's new %r. SomeTimestamp 2644 B %a added a new %r to [his/her] profile. SomeTimestamp %a = the User_ID of the person doing the action %r = the receiving object %o = the owner of the receiving object (for example the owner of the album) (NULL if %r is a user) Questions: Is this a smart (efficient/scalable) way to move forward? How can I show messages like: "User_B added 4 new photos to his profile."?

• How do I model teams and gameplay in this scorekeeping application?

  - by Eric Hill

  I'm writing a scorekeeping application for card game that has a few possibly-interesting constraints. The application accepts user registrations for players, then lets them check-in to a particular game (modeled as Event). After the final player registers, the app should generate teams, singles or doubles, depending on the preference of the person running the game and some validations (can't do doubles if there's an odd number checked in). There are @event.teams.count rounds in the game. To sum up: An event consists of `@event.teams.count` rounds; Teams can have 1 or more players Events have n or n/2 teams (depending on whether it's singles or doubles) Users will be members of different teams at different events Currently I have a rat's nest of associations: class User < ActiveRecord::Base has_many :teams, :through => :players has_many :events, :through => :teams class Event < ActiveRecord::Base has_many :rounds has_many :teams has_many :players, :through => :teams class Player < ActiveRecord::Base belongs_to :user belongs_to :team end class Team < ActiveRecord::Base has_many :players belongs_to :event end class Round < ActiveRecord::Base belongs_to :event belongs_to :user end The sticky part is team generation. I have basically a "start game" button that should freeze the registrations and pair up teams either singly or doubly, and render to Round#new so that the first (and subsequent) matches can be scored. Currently I'm implementing this as a check on Round#new that calls Event#generate_teams and displays the view: # Event#generate_teams def generate_teams # User has_many :events, :through => :registrations # self.doubles is a boolean denoting 2 players per team registrations.in_groups_of(self.doubles ? 2 : 1, nil).each do |side| self.teams << Player.create(self,side) end end Which doesn't work. Should there maybe be a Game model that ties everything together rather than (my current method) defining the game as an abstraction via the relationships between Events, Users, and Rounds (and Teams and Players and etc.)? My head is swimming.

• Showing an array of certain pages with WP_Query in Wordpress

  - by Ragnar

  What I'm trying to achieve is showing only certain pages in a loop. 3 certain pages, not more, not less. I've tried many things but I just can't complete it. <?php $special_tabs = new WP_Query(array('post_type' => 'page', 'post_in' => array(100,102,104))); ?> What this does, from what I understand, is that it shows an array of pages and then includes those ID's there as well. <?php $special_tabs = new WP_Query(array ('page_id' => 100)); ?> And this shows only ONE certain page, it doesn't support the showing of array of different IDs. I'm sure I am not the first person to have such specific needs and I'm certain there is a relatively simple way to achieve what I'm trying to achieve, but I just can't come up with a solution or to find one. Can anybody please help me with this? Many thanks in advance!

• How do I bring forward the SELECTED option in PHP from MySQL?

  - by Derek

  Hi all, In my update form, I want the fields to recall the values that are already stored. This is very simple in a text field, but for my drop down () I'm having trouble with PHP reading the already stored name of user. Here is my query and code: $sql = "SELECT users.user_id, users.name FROM users"; $result = mysql_query($sql, $connection) or die ("Couldn't perform query $sql <br />".mysql_error()); $row = mysql_fetch_array($result);?> <label>Designated Person:</label> <select name="name" id="name"> <option value="<?php echo $row['user_id']?>" SELECTED><?php echo $row['name']?> - Current</option> <?php while($row = mysql_fetch_array($result)) { ?> <option value="<?php echo $row['user_id']; if (isset($_POST['user_id']));?>"><?php echo $row['fullname']?></option> <?php } ?> The result of this displays all of the users (as required) and lets me select a user then perform the change successfully...however the 'SELECTED' is always the first one in my database and never the user that was selected when my activity was added :( !!!

• Where should I put contextual data related to an Object that is not really a property of the object?

  - by RenderIn

  I have a Car class. It has three properties: id, color and model. In a particular query I want to return all the cars and their properties, and I also want to return a true/false field called "searcherKnowsOwner" which is a field I calculate in my database query based on whether or not the individual conducting the search knows the owner. I have a database function that takes the ID of the searcher and the ID of the car and returns a boolean. My car class looks like this (pseudocode): class Car{ int id; Color color; Model model; } I have a screen where I want to display all the cars, but I also want to display a flag next to each car if the person viewing the page knows the owner of that car. Should I add a field to the Car class, a boolean searcherKnowsOwner? It's not a property of the car, but is actually a property of the user conducting the search. But this seems like the most efficient place to put this information.

• Should I use two queries, or is there a way to JOIN this in MySQL/PHP?

  - by Jack W-H

  Morning y'all! Basically, I'm using a table to store my main data - called 'Code' - a table called 'Tags' to store the tags for each code entry, and a table called 'code_tags' to intersect it. There's also a table called 'users' which stores information about the users who submitted each bit of code. On my homepage, I want 5 results returned from the database. Each returned result needs to list the code's title, summary, and then fetch the author's firstname based on the ID of the person who submitted it. I've managed to achieve this much so far (woot!). My problem lies when I try to collect all the tags as well. At the moment this is a pretty big query and it's scaring me a little. Here's my problematic query: SELECT code.*, code_tags.*, tags.*, users.firstname AS authorname, users.id AS authorid FROM code, code_tags, tags, users WHERE users.id = code.author AND code_tags.code_id = code.id AND tags.id = code_tags.tag_id ORDER BY date DESC LIMIT 0, 5 What it returns is correct looking data, but several repeated rows for each tag. So for example if a Code entry has 3 tags, it will return an identical row 3 times - except in each of the three returned rows, the tag changes. Does that make sense? How would I go about changing this? Thanks! Jack

• Making pygtksourceview work in windows

  - by Dani

  So, I'm trying to get gtksourceview python bindings work under windows (I'm developing a cross platform gtk application that shows code, so gtksourceview seemed like a natural choice). I have pygtk installed and working (I followed the instructions in http://www.pygtk.org/downloads.html) I tried the instructions in http://projects.gnome.org/gtksourceview/ for gtksourceview. Here is what I did: Downloaded and extracted the latest gtksourceview window binaries from: http://ftp.gnome.org/pub/gnome/binaries/win32/gtksourceview/2.10/gtksourceview-2.10.0.zip The website said gtksourceview needs libxml, so I downloaded and extracted the latest libxml window binaries from: http://xmlsoft.org/sources/win32/libxml2-2.7.6.win32.zip Added the folders containing dll files to the PATH (in my computer they were c:\opt\gtksourceview\bin; C:\opt\libxml2-2.7.6.win32\bin) Installed pygtksourceview with the windows installer: http://ftp.gnome.org/pub/gnome/binaries/win32/pygtksourceview/2.10/pygtksourceview-2.10.0.win32-py2.6.exe Renamed the file libxml2.dll to libxml2-2.dll (after running depends on the gtksourceview dll) Now, the gtksouceview widget seems to work, until I'm trying to set the code's language. When I do that python crashes. Here is how I crash it in the console (the simplest way i could come up with): >>>import gtksourceview2 >>>lang = gtksourceview2.language_manager_get_default().get_language('cpp') >>>lang.get_style_ids() I'm hoping I'm not the first person to use gtksourceview in python on windows. Any ideas what I should try?

• Common NSNotification mistakes?

  - by Ben Packard

  A simplification... A building has an array of apartment objects. Each apartment has a single currentTenant. These tenants are of type Person. Note that currentTenant doesn't have a reference to the apartment, so can't send information back up the chain. When a tenant has a plumbing issue he raises an NSNotification: [nc postNotificationName:@"PlumbingIssue" object:self]; Each Apartment observes notifications ONLY FROM it's own current tenant (this is set up when the apartment is built, before there is a current tenant): [nc addObserver:self selector:@selector(alertBuildingManager:) name:@"PlumbingIssue" object:[self currentTenant]; When the apartment receives a notification from it's own currentTenant, it sends it's own notification, "PlumberRequired", along with the apartment number and the currentTenant in an NSDictionary. Apartment observes these notifications, which it will take from any apartment (or other object): [nc addObserver:self selector:@selector(callPlumber) name:@"PlumberRequired" object:nil]; Is there something I could be getting fundamentally wrong here? What's happening is that the apartment is receiving notifications from any and all currentTenants, rather than jus it's own. Sorry that the actual code is a bit too unwieldy to post. Was just wondering if there's a gap in my understanding about observing notifications from a particular sender?

• Natural problems to solve using closures

  - by m.u.sheikh

  I have read quite a few articles on closures, and, embarassingly enough, I still don't understand this concept! Articles explain how to create a closure with a few examples, but I don't see any point in paying much attention to them, as they largely look contrived examples. I am not saying all of them are contrived, just that the ones I found looked contrived, and I dint see how even after understanding them, I will be able to use them. So in order to understand closures, I am looking at a few real problems, that can be solved very naturally using closures. For instance, a natural way to explain recursion to a person could be to explain the computation of n!. It is very natural to understand a problem like computing the factorial of a number using recursion. Similarly, it is almost a no-brainer to find an element in an unsorted array by reading each element, and comparing with the number in question. Also, at a different level, doing Object-oriented programming also makes sense. So I am trying to find a number of problems that could be solved with or without closures, but using closures makes thinking about them and solving them easier. Also, there are two types to closures, where each call to a closure can create a copy of the environment variables, or reference the same variables. So what sort of problems can be solved more naturally in which of the closure implementations?

• Please take a stab at this VB.Net Oracle-related sample and help me with String.Format.

  - by Hamish Grubijan

  If the database is not Oracle, it is MS SQl 2008. My task: if Oracle, add two more parameters when calling a stored proc. Oracle and MSFT stored procs are generated; Oracle ones have 3 extra parameters: Vret_val out number, Vparam2 in out number, Vparam3 in out number, ... the rest (The are not actually named Vparam2 and Vparam3, but this should not matter). So, the code for a helper VB.Net class that calls a stored proc: Imports System.Data.Odbc Imports System.Configuration Dim objCon As OdbcConnection = Nothing Dim objAdapter As OdbcDataAdapter Dim cmdCommand As New OdbcCommand Dim objDataTable As DataTable Dim sconnection As String Try sconnection = mConnectionString objAdapter = New OdbcDataAdapter objCon = New OdbcConnection(sconnection) objCon.Open() objAdapter.SelectCommand = cmdCommand objAdapter.SelectCommand.Connection = objCon objAdapter.SelectCommand.CommandType = CommandType.StoredProcedure objAdapter.SelectCommand.CommandTimeout = Globals.mReportTimeOut If Not mIsOracle Then objAdapter.SelectCommand.CommandText = String.Format("{{call {0}}}", spName) Else Dim returnValue As New OdbcParameter returnValue.Direction = ParameterDirection.Output returnValue.ParameterName = "@Vret_val" returnValue.OdbcType = OdbcType.Numeric objAdapter.SelectCommand.Parameters.Add(returnValue) objAdapter.SelectCommand.CommandText = String.Format("{{call {0}(?)}}", spName) End If Try objDataTable = New DataTable(spName) objAdapter.Fill(objDataTable) Catch ex As Exception ... Question: I am puzzled as to what String.Format("{{call {0}(?)}}", spName) does, in particular the (?) part. My understanding of the String.Format is that it will simply replace {0} with spName. The {{, }}, and (?) do throw me off because { reminds me of formatting, (?) hints at some advanced regex use. Unfortunately I am getting little help from a key person who is on vacation without a leash [smart]phone. I am guessing that I simply add 5 more lines for each additional parameter, and change String.Format("{{call {0}(?)}}", spName) to String.Format("{{call {0}(?,?,?)}}", spName). I forgot to mention that I am coding this "blindly" - I have a compiler to help me, but no environment set up to test this. This will be over in a few days, but I need to do my best to try finishing it on time :) Thanks.

• looping through JSON array

  - by Phil Jackson

  Hi all. I have recently posted another question which straight away users pointed me in the right direction. $.ajax({ type: 'POST', url: './', data: 'token=' + token + '&re=8', cache: false, timeout: 5000, success: function(html){ auth(html); var JSON_array = eval(html); alert(JSON_array[0].username); } }); this returns the data correctly but I want to perform a kind of 'foreach'. the array contains data about multiple incoming and outgoing Instant Messages. So if a user is talking to more than one person at a time i need to loop through. the array's structure is as follows. Array ( [0] => Array ( [username] => Emmalene [contents] => <ul><li class="name">ACTwebDesigns</li><li class="speech">helllllllo</li></ul> <ul><li class="name">ACTwebDesigns</li><li class="speech">sds</li></ul> <ul><li class="name">ACTwebDesigns</li><li class="speech">Sponge</li><li class="speech">dick</li></ul> <ul><li class="name">ACTwebDesigns</li><li class="speech">arghh</li></ul> ) ) any help very much appreciated.

• ldap login form works, but need to add active-directory group access

  - by Brad

  I created a form that asks you to log in, then verifies the user/pass against the ldap server/active-directory, if successful, it creates a session, which will be checked on every page. Now I want to check the session, which is the username of the person who is logged in, and do a search for them using ldap_search, so I can check what group they belong to and pass that group thru a function to verify that they can view that page. Each page will accessible to a certain group or groups of users, which those groups are defined within Active Directory. I am unsure on how I can do that using ldap_search, or maybe that is just one piece of the puzzle I am trying to solve. Any help is appreciated - thank you! In the example code below, it is seeing if the user belongs to the student active-directory group (I do not know if this code works, but it should give you an idea of what I want to accomplish). $filter = "CN=StudentCN=Users,dc=domain,dc=control"; $result = ldap_search($ldapconn,$filter,$valid_session_username); if($result == TRUE) { print $valid_session_username.' does have access to this page'; } else { print $valid_session_username.' does NOT have access to this page'; }

• WPF: Horizontal Alignment

• When to choose which machine learning classifier?

  - by LM

  Suppose I'm working on some classification problem. (Fraud detection and comment spam are two problems I'm working on right now, but I'm curious about any classification task in general.) How do I know which classifier I should use? (Decision tree, SVM, Bayesian, logistic regression, etc.) In which cases is one of them the "natural" first choice, and what are the principles for choosing that one? Examples of the type of answers I'm looking for (from Manning et al.'s "Introduction to Information Retrieval book": http://nlp.stanford.edu/IR-book/html/htmledition/choosing-what-kind-of-classifier-to-use-1.html): a. If your data is labeled, but you only have a limited amount, you should use a classifier with high bias (for example, Naive Bayes). [I'm guessing this is because a higher-bias classifier will have lower variance, which is good because of the small amount of data.] b. If you have a ton of data, then the classifier doesn't really matter so much, so you should probably just choose a classifier with good scalability. What are other guidelines? Even answers like "if you'll have to explain your model to some upper management person, then maybe you should use a decision tree, since the decision rules are fairly transparent" are good. I care less about implementation/library issues, though. Also, for a somewhat separate question, besides standard Bayesian classifiers, are there 'standard state-of-the-art' methods for comment spam detection (as opposed to email spam)? [Not sure if stackoverflow is the best place to ask this question, since it's more machine learning than actual programming -- if not, any suggestions for where else?]

• Global Temporary Table "On commit delete rows" functionality discrepancy.

  - by TomatoSandwich

  I have a global temporary table. I called my GTT, for that was it's initials. My GTT never hurt anyone, and did everything I bade of it. I asked my GTT to delete rows on commit. This is a valid function in the creation script of my GTT in oracle. I wanted to be able to have different users see GTT with their own data, and not the data of other people's sessions. 'Delete rows on commit' worked perfectly in our test environment. GTT and I were happy. But then, I deployed GTT as part of an update to functionality to a client's database. The database doesn't like to play well with GTT. GTT called me up all upset and worried, because it wasn't holding any data any more, and didn't know why. GTT told me that if someone did: insert into my_GTT (description) values ('Happy happy joy joy') he would sing-song back: 1 row inserted. However, if the same person tried select * from my_GTT; GTT didn't know what to do, and he replied 0 rows returned. GTT was upset that he didn't know what his playmate had inserted. Please, Stackoverflow, why would GTT forget what was placed into him? He can remember perfectly well at home, but out in the cold harsh world, he just gets so scared. :(

• Parse usable Street Address, City, State, Zip from a string

  - by Rob Allen

  Problem: I have an address field from an Access database which has been converted to Sql Server 2005. This field has everything all in one field. I need to parse out the individual sections of the address into their appropriate fields in a normalized table. I need to do this for approximately 4,000 records and it needs to be repeatable. Here are the rules for this exercise: 1 - no whining about how this should have been separate fields in the first place, we are often confronted with less than ideal situations and have to make the best of them 2- for this post, use any language you want 3- feel free to play code golf 4 - Assume an address in the US (for now) 5 - assume that the input string will sometimes contain an addressee (the person being addressed) and/or a second street address (i.e. Suite B) 6 - states may be abbreviated 7 - zip code could be standard 5 digit or zip+4 8 - there are typos in some instances UPDATE: In response to the questions posed, standards were not universally followed, I need need to store the individual values, not just geocode and errors means typo (corrected above) Sample Data: A.

• How do I get this sql to linq? Multiple groups

  - by Dwight T

  For a db person, LINQ can be frustrating. I need to convert the following SQL into Linq. SELECT COUNT(o.objectiveid), COUNT(distinct r.ReviewId), l.Abbreviation FROM Objective o JOIN Review r on r.ReviewId = o.ReviewId and r.ReviewPeriodId = 3 and r.IsDeleted = 0 JOIN Position p on p.PositionId = r.EmployeePositionId and p.DivisionId = 2 JOIN Location l on l.LocationId = p.LocationId GROUP BY l.Abbreviation The group by nested example might be the way I have to go, but not sure. Doing one group by I have used the following code: var query = from rev in db.Reviews .Where(r => r.IsDeleted == false && r.ReviewPeriodId == reviewPeriodId) from obj in db.Objectives .Where(o => o.ReviewId == rev.ReviewId && o.IsDeleted == false) from pos in db.Positions .Where(p => rev.EmployeePositionId == p.PositionId && p.IsDeleted == false && p.DivisionId == divisionId ) from loc in db.Locations .Where(l => pos.LocationId == l.LocationId) group loc by loc.Abbreviation into locgroup select new ReportResults { KeyId = 0, Description = locgroup.Key, Count = locgroup.Count() }; return query.ToList(); What is the correct way? Thanks

• JSON feed to Java Object

  - by mnml

  Hi, I would like to know if there is a webpage/software that can "translate" a Json feed object to a Java object with attributes. For example : { 'firstName': 'John', 'lastName': 'Smith', 'address': { 'streetAddress': '21 2nd Street', 'city': 'New York' } } Would become: class Person { private String firstName; private String lastName; private Address address; public String getFirstName() { return firstName; } public String getLastName() { return lastName; } public Address getAddress() { return address; } public void setFirstName(String firstName) { this.firstName = firstName; } public void setLastName(String lastName) { this.lastName = lastName; } public void setAddress(Address address) { this.address = address; } public String toString() { return String.format("firstName: %s, lastName: %s, address: [%s]", firstName, lastName, address); } } class Address { private String streetAddress; private String city; public String getStreetAddress() { return streetAddress; } public String getCity() { return city; } public void setStreetAddress(String streetAddress) { this.streetAddress = streetAddress; } public void setCity(String city) { this.city = city; } public String toString() { return String.format("streetAddress: %s, city: %s", streetAddress, city); } } I'm not asking that because I'm lazy, but the JSON I would like to parse has quite a lot of attribute.

• Checking for valid email addresses

  - by Roland

  I'm running a website with more than 60 000 registered users. Every week notifications are send to these users via email, now I've noticed some of the mail addresses do not exists anymore eg. the domain address is valid but the email name en asdas@ is not valid anymore since person does not work at a company anymore etc. Now I'm looping through the database and doing some regular expression checks and checking if the MX records exist with the following two functions function verify_email($email){ if(!preg_match('/^[_A-z0-9-]+((\.|\+)[_A-z0-9-]+)*@[A-z0-9-]+(\.[A-z0-9-]+)*(\.[A-z]{2,4})$/',$email)){ return false; } else { return true; } } // Our function to verify the MX records function verify_email_dns($email){ list($name, $domain) = split('@',$email); if(!checkdnsrr($domain,'MX')){ return false; } else { return true; } } If the email address is in an invalid format or the domain does not exists I delete the users account. Are there any methods I could use to check if the email address still exists or not if the domain name is valid and the email address is in the correct format? For example [email protected] does not exist anymore but test.com is a valid domain name.

• Website Live Chat Script - Interface With Windows Live Messenger?

  - by Sootah

  Hello again fellow StackOverflow users! What I am looking for currently is your opinions on the what the best live chat script would be for my website. I'd be using this on both my local computer repair (which I've not really set up yet) company's site, as well as my other technical support site that is geared more towards showing people how to fix whatever problem they have themselves. It'll be a little bit before I launch it on either site, as I need to find a good design for my local computer repair company's site, as well as redesign TweaksForGeeks.com's layout so that it's more magazine like. (If you have any suggestions on good Wordpress templates for these, that'd also be swell. :) ) Features I'd like for the live chat script to have: (if possible) Real-time posting of messages (or as close to real time as possible) Integration into my Windows Live Messenger account - By this I mean it'd be handy if instead of me having to man a separate open browser window and constantly check it for new messages, it'd be much more convenient if it would instead just allow me to receive and respond to messages via my Windows Live account the same way I'd chat with any other person on my contact list. Sound notification of new messages when the chat isn't the focused window - In the event that using Windows Messenger isn't possible then I'd need it to notify me upon receipt of a new message. Recording of chat transcripts - This is a MUST HAVE Easy customization - I'll likely want to modify how it looks and whatnot, in addition to the fact that I'm going to set it up so that the chat transcripts can be posted to my site easily in order to be useful to my other visitors later on. With all that in mind, what is available out there? I've not really researched this at all yet; aside from doing a cursory search just before I decided to ask my StackOverflow brothers. As always, thank you! -Sootah

• how to check null value of Integer type field in ASP.NET MVC view?

  - by Vikas

  Hi, I have integer type field in database which is having property "Not Null". when i create a view & do a validation, if i left that field blank, it will consider it as 0 so i can not compare it with 0 because if someone insert a value 0 then it will be considered as error! one another problem is that i am using Model error as described in the book "ASP.NET MVC 1.0" @ Scott Gu blog. And I am checking the value in partial class of object (created by LINQ-To-SQL). i.e public partial class Person { public bool IsValid { get { return (GetRuleViolations().Count() == 0); } } public IEnumerable<RuleViolation> GetRuleViolations() { if (String.IsNullOrEmpty(Name)) yield return new RuleViolation("Name is Required", "Name"); if (Age == 0) yield return new RuleViolation("Age is Required", "Age"); yield break; } partial void OnValidate(ChangeAction action) { if (!IsValid) throw new ApplicationException("Rule violations prevent saving"); } } There is also problem with range. Like in database if i declared as smallint i.e. short in c#, now if i exceed that range then it gives error as "A Value is reguired". so finally is there any best way for validation in ASP.NET MVC?

• Integrating Magento with a simple static website.

  - by ExtraLean

  Magento is an awesomely powerful ecommerce platform. That said, it is also very complex, and I'd like to know if there is a relatively simple way to utilize Magento as our mISV site's backend to fulfill orders without actually "using" Magento's framework to build the site, run the site, etc. In other words, I don't want to use the built-in CMS, etc. since we have a static website already built. I'd just like our Buy Now buttons to utilize the checkout stuff, and would like to be able to use the back-end part to keep track of orders etc. I was able to accomplish this "fairly" easily with osCommerce, but Magento is proving to be a little more difficult to wrap my head around since I've only started looking at it for a few days now. I found another person asking this same exact question on the Magento wiki (along with several others in the forum), and none of them ever receive a reply for some reason. I noticed that there are may Magento experts on Stack Overflow, so I thought I'd give it a go here. This is an example of one question asked by someone on their wiki, and it captures the essence of what I'm trying to accomplish: Hi, as far as I understand, all shopping cart/eCommerce solutions I see are full featured PHP driven web sites. This means that all the pages the user interacts with, are server generated, and thus, the experience, is tied to the magento framework/workflow. I’d like to integrate bits and pieces of eCommerce/shopping cart in my existing website. Effectively, I’d like to have: 1) on a product information page, a “buy now/add to cart” button that adds to a cart 2) on every page, a view cart/checkout option 3) on a checkout page, with additional content already in place, having the magento “checkout” block integrated in the page (and not the entire page generated from Magento). Have any of you done this with Magento? This is for a simple one-product website so any advice you could share would be highly appreciated.

• What is the optimum way to secure a company wide wiki?

  - by Mark Robinson

  We have a wiki which is used by over half our company. Generally it has been very positively received. However, there is a concern over security - not letting confidential information fall into the wrong hands (i.e. competitors). The default answer is to create a complicated security matrix defining who can read what document (wiki page) based on who created it. Personally I think this mainly solves the wrong problem because it creates barriers within the company instead of a barrier to the external world. But some are concerned that people at a customer site might share information with a customer which then goes to the competitor. The administration of such a matrix is a nightmare because (1) the matrix is based on department and not projects (this is a matrix organisation), and (2) because in a wiki all pages are by definition dynamic so what is confidential today might not be confidential tomorrow (but the history is always readable!). Apart from the security matrix, we've considered restricting content on the wiki to non super secret stuff, but off course that needs to be monitored. Another solution (the current) is to monitor views and report anything suspicious (e.g. one person at a customer site having 2000 views in two days was reported). Again - this is not ideal because this does not directly imply a wrong motive. Does anyone have a better solution? How can a company wide wiki be made secure and yet keep its low threshold USP? BTW we use MediaWiki with Lockdown to exclude some administrative staff.
