• Wordpress Installation (on IIS and SQL Server)

  - by Davide Mauri

  To proceed with the installation of Wordpress on SQL Server and IIS, first of all, you need to do the following steps Create a database on SQL Server that will be used by Wordpress Create login that can access to the just created database and put the user into ddladmin, db_datareader, db_datawriter roles Download and unpack Wordpress 3.3.2 (latest version as of 27 May 2012) zip file into a directory of your choice Download the wp-db-abstraction 1.1.4 (latest version as of 27 May 2012) plugin from wordpress.org website Now that the basic action has been done, you can start to setup and configure your Wordpress installation. Unpack and follow the instructions in the README.TXT file to install the Database Abstraction Layer. Mainly you have to: Upload wp-db-abstraction.php and the wp-db-abstraction directory to wp-content/mu-plugins.  This should be parallel to your regular plugins directory.  If the mu-plugins directory does not exist, you must create it. Put the db.php file from inside the wp-db-abstraction.php directory to wp-content/db.php Now you can create an application pool in IIS like the following one Create a website, using the above Application Pool, that points to the folder where you unpacked Wordpress files. Be sure to give the “Write” permission to the IIS account, as pointed out in this (old, but still quite valid) installation manual: http://wordpress.visitmix.com/development/installing-wordpress-on-sql-server#iis Now you’re ready to go. Point your browser to the configured website and the Wordpress installation screen will be there for you. When you’re requested to enter information to connect to MySQL database, simply skip that page, leaving the default values. If you have installed the Database Abstraction Layer, another database installation screen will appear after the one used by MySQL, and here you can enter the configuration information needed to connect to SQL Server. After having finished the installation steps, you should be able to access and navigate your wordpress site.  A final touch, and it’s done: just add the needed rewrite rules http://wordpress.visitmix.com/development/installing-wordpress-on-sql-server#urlrewrite and that’s it! Well. Not really. Unfortunately the current (as of 27 May 2012) version of the Database Abstraction Layer (1.1.4) has some bugs. Luckily they can be quickly fixed: Backslash Fix http://wordpress.org/support/topic/plugin-wp-db-abstraction-fix-problems-with-backslash-usage Select Top 0 Fix Make the change to the file “.\wp-content\mu-plugins\wp-db-abstraction\translations\sqlsrv\translations.php” suggested by “debettap”   http://sourceforge.net/tracker/?func=detail&aid=3485384&group_id=315685&atid=1328061 And now you have a 100% working Wordpress installation on SQL Server! Since I also wanted to take advantage of SQL Server Full Text Search, I’ve created a very simple wordpress plugin to setup full-text search and to use it as website search engine: http://wpfts.codeplex.com/ Enjoy!

• How is made sure magnetic or electric fields from devices like transformers or fans close nearby do

  - by matnagel

  Fans and transformers which are inside the server case create magnetic and electric fields. Electric fields can be easily shielded, but what about magnetic fields, they can only be shielded with high cost materials like mu metal http://en.wikipedia.org/wiki/Mu-metal If a hard drive is installed too close to an intense transformer field, how is the magnetically stored information on the ferromagnetic surfaces of the disk kept safe? Even if drives are shielded, where are the limits? Is there some technical investigation or recommendation from manufacturers about this? (I never heard about something and never had any problem but I am interested in some facts. This is much preferred over what you believe or a habit you developed. Please try to give some solid infromation.) I have built and repaired many servers and sometimes I did put the harddrive on top of the power supply. Edit: This question is not about frequencies that could affect the drive via the power or data connectors of the drive, those are electronically decoupled and that's another question. Edit 2: The wikipedia page states that the motor inside the drive is shielded with mu metal. It is obvious that manufactureres have to take care of this. This question is about such influences from outside the drive.

• How to return this XML-RPC response in an array using PHP?

  - by mind.blank

  I'm trying to put together a WordPress plugin and I want to grab a list of all categories (of other WordPress blogs) via XML-RPC. I have the following code and it looks like it works so far: function get_categories($rpcurl,$username,$password){ $rpcurl2 = $rpcurl."/xmlrpc.php"; $params = array(0,$username,$password,true); $request = xmlrpc_encode_request('metaWeblog.getCategories',$params); $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $rpcurl2); curl_setopt($ch, CURLOPT_HEADER, false); curl_setopt($ch, CURLOPT_HTTPHEADER, array("Content-Type: text/xml")); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_TIMEOUT, 10); curl_setopt($ch, CURLOPT_POSTFIELDS, $request); $results = curl_exec($ch); $res = xmlrpc_decode($results); curl_close($ch); return $res; } If I use $res I get the following string as the response: Array If I use $results then I get: categoryId17 parentId0 descriptionTest categoryDescription categoryNameTest htmlUrlhttp://test.yoursite.com/?cat=17 rssUrlhttp://test.yoursite.com/?feed=rss2&amp;cat=17 categoryId1 parentId0 descriptionUncategorized categoryDescription categoryNameUncategorized htmlUrlhttp://test.yoursite.com/?cat=1 rssUrlhttp://test.yoursite.com/?feed=rss2&amp;cat=1 I need to pull out the names after description so Uncategorized and Test in this case. It's my first time coding in PHP. I got these results by echoing them to the page, so not sure if they get changed in that process or not... By the way I modified the above code from one that posts to a WordPress blog remotely so maybe I haven't set some of the options correctly? With var_dump($res) I get: array(2) { [0]=> array(7) { ["categoryId"]=> string(2) "17" ["parentId"]=> string(1) "0" ["description"]=> string(4) "Test" ["categoryDescription"]=> string(0) "" ["categoryName"]=> string(4) "Test" ["htmlUrl"]=> string(40) "http://test.youreventwebsite.com/?cat=17" ["rssUrl"]=> string(54) "http://test.youreventwebsite.com/?feed=rss2&cat=17" } [1]=> array(7) { ["categoryId"]=> string(1) "1" ["parentId"]=> string(1) "0" ["description"]=> string(13) "Uncategorized" ["categoryDescription"]=> string(0) "" ["categoryName"]=> string(13) "Uncategorized" ["htmlUrl"]=> string(39) "http://test.youreventwebsite.com/?cat=1" ["rssUrl"]=> string(53) "http://test.youreventwebsite.com/?feed=rss2&cat=1" } }

• How to use jQuery to generate 2 new associated objects in a nested form?

  - by mind.blank

  I have a model called Pair, which has_many :questions, and each Question has_one :answer. I've been following this railscast on creating nested forms, however I want to generate both a Question field and it's Answer field when clicking on an "Add Question" link. After following the railscast this is what I have: ..javascripts/common.js.coffee: window.remove_fields = (link)-> $(link).closest(".question_remove").remove() window.add_fields = (link, association, content)-> new_id = new Date().getTime() regexp = new RegExp("new_" + association, "g") $(link).before(content.replace(regexp, new_id)) application_helper.rb: def link_to_add_fields(name, f, association) new_object = f.object.class.reflect_on_association(association).klass.new fields = f.simple_fields_for(association, new_object, :child_index => "new_#{association}") do |builder| render(association.to_s.singularize + "_fields", :f => builder) end link_to_function(name, "window.add_fields(this, \"#{association}\", \"#{escape_javascript(fields)}\")", class: "btn btn-inverse") end views/pairs/_form.html.erb: <%= simple_form_for(@pair) do |f| %> <div class="row"> <div class="well span4"> <%= f.input :sys_heading, label: "System Heading", placeholder: "required", input_html: { class: "span4" } %> <%= f.input :heading, label: "User Heading", input_html: { class: "span4" } %> <%= f.input :instructions, as: :text, input_html: { class: "span4 input_text" } %> </div> </div> <%= f.simple_fields_for :questions do |builder| %> <%= render 'question_fields', f: builder %> <% end %> <%= link_to_add_fields "<i class='icon-plus icon-white'></i> Add Another Question".html_safe, f, :questions %> <%= f.button :submit, "Save Pair", class: "btn btn-success" %> <% end %> _question_fields.html.erb partial: <div class="question_remove"> <div class="row"> <div class="well span4"> <%= f.input :text, label: "Question", input_html: { class: "span4" }, placeholder: "your question...?" %> <%= f.simple_fields_for :answer do |builder| %> <%= render 'answer_fields', f: builder %> <% end %> </div> </div> </div> _answer_fields.html.erb partial: <%= f.input :text, label: "Answer", input_html: { class: "span4" }, placeholder: "your answer" %> <%= link_to_function "remove", "remove_fields(this)", class: "float-right" %> I'm especially confused by the reflect_on_association part, for example how does calling .new there create an association? I usually need to use .build Also for a has_one I use .build_answer rather than answers.build - so what does this mean for the jQuery part?

  - by Idle Mind

  I am in the process of creating a knowledgebase website for my office and I find bootstrap pretty awesome. Now, people at work, which may not be HTML savvy, will be creating new articles and then posting them to this knowledge base. Is there something you can recommend that would allow such type of user to create a document on somthing similar to Microsoft Word but web based and then publish? Or do I have to write it from scratch? Thanks for any help.

• C# MVC: User Password Reset Controller: Issues with email addresses as usernames

  - by 109221793

  Hi guys, I have written the code below for resetting users passwords (am using the aspnet membership api) in an C# MVC application, and tested successfully on a sample tutorial application (MVC Music Store). Skip to the end if you wish to read problem description first. InactiveUsers View (Partial View) <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<System.Web.Security.MembershipUserCollection>" %> <table class="normal" style="width: 100%; background-color: White;"> <tr> <th>User Name</th> <th>Last Activity date</th> <th>Locked Out</th> </tr> <%foreach (MembershipUser user in Model){ %> <tr> <td><%: Html.RouteLink(user.UserName, "AdminPassword", new { username = user.UserName }) %></td> <td><%: user.LastActivityDate %></td> <td><%: user.IsLockedOut %></td> </tr> <% }%> </table> InactiveUsers Controller public ActionResult InactiveUsers() { var users = Membership.GetAllUsers(); return View(users); } changeUserPassword GET and POST Controllers public ActionResult changeUserPassword(string username) { ViewData["username"] = username; return View(); } [HttpPost] public ActionResult changeUserPassword(ChangePasswordModel model, FormCollection values) { string username = values["username"]; string password = values["password"]; string confirmPassword = values["confirmPassword"]; MembershipUser mu = Membership.GetUser(username); if (password == confirmPassword) { if (mu.ChangePassword(mu.ResetPassword(), password)) { return RedirectToAction("Index", "ControlPanel"); } else { ModelState.AddModelError("", "The current password does not meet requirements"); } } return View(); } I also modified the Global.asax.cs file to cater for my route in the InactiveUsers partial: // Added in 10/01/11 RouteTable.Routes.MapRoute( "AdminPassword", // routename "ControlPanel/changeUserPassword/{username}", new { controller = "ControlPanel", action = "changeUserPassword", username = UrlParameter.Optional } ); // END Now, when I tested on the MVC Music Store, all of my usernames were just words, e.g. Administrator, User, etc. However now I am applying this code to a situation in my workplace and it's not working out quite as planned. The usernames used in my workplace are actually email addresses and I think this is what is causing the problem. When I click on the RouteLink in the partial InactiveUsers view, it should bring me to the reset password page with a url that looks like this: http://localhost:83/ControlPanel/changeUserPassword/[email protected], HOWEVER, what happens when I click on the RouteLink is an error is thrown to say that the view changeUserPassword cannot be found, and the URL looks like this: http://localhost:83/ControlPanel/changeUserPassword/example1%40gmail.com - See how the '@' symbol gets messed up? I've also debugged through the code, and in my GET changeUserPassword, the username is populating correctly: [email protected], so I'm thinking it's just the URL that's messing it up? If I type in the URL manually, the changeUserPassword view displays, however the password reset function does not work. An 'Object reference not set to an instance of an object' exception is thrown at the if (mu.ChangePassword(mu.ResetPassword(), password)) line. I think if I could solve the first issue (URL '@' symbol problem) it might help me along with my second issue. Any help would be appreciated :) Stack Trace - as requested Source Error: An unhandled exception was generated during the execution of the current web request.

• Újabb házassági terv az adatbázis piacon: Sybase és SAP

  - by Fekete Zoltán

  Az Oracle az utóbbi évben technológiai és alkalmazás oldalon több mint 50 céget vásárolt meg, legutóbb a hardver-operációs rendszer, Java, IDM, virtualizáció és számos más téren is innovatív Sun céget. Ráadásul az Oracle best-of-breed azaz iparági vezeto cégekkel és mogoldásokkal erosíti a portfólióját. Az Oracle hosszú évek óta az adattárházak (data wrehouse) területén is a Gartner szerint a piacvezetok mágikus négyzetében van. Ennek a területnek vezeto megoldása az Oracle Database optimalizált hardveren futtatása az Exadata / Database Machine területen. Az Oracle Database mind tranzakciókezelésre mind adattárház feldolgozásra, mind ezen megoldások egy környezetben futtatására optimalizált megoldás. Az SAP korábban meglehetosen elítélte az Oracle best-of-breed felvásárlási stratégiáját, mondván az nem vezet semmire. :) Most a megmaradék önálló cégek közül a Sybase-t szemelte ki. A BBC híre. Kicsit soknak tunik az 5,8 milliárd dollár? Érdekes, hogy a cikk szerint a felvásárlási terv hírére az SAP részvény árfolyam 40 centtel esett.

• Type checking and recursive types (Writing the Y combinator in Haskell/Ocaml)

  - by beta

  When explaining the Y combinator in the context of Haskell, it's usually noted that the straight-forward implementation won't type-check in Haskell because of its recursive type. For example, from Rosettacode [1]: The obvious definition of the Y combinator in Haskell canot be used because it contains an infinite recursive type (a = a -> b). Defining a data type (Mu) allows this recursion to be broken. newtype Mu a = Roll { unroll :: Mu a -> a } fix :: (a -> a) -> a fix = \f -> (\x -> f (unroll x x)) $ Roll (\x -> f (unroll x x)) And indeed, the “obvious” definition does not type check: ?> let fix f g = (\x -> \a -> f (x x) a) (\x -> \a -> f (x x) a) g <interactive>:10:33: Occurs check: cannot construct the infinite type: t2 = t2 -> t0 -> t1 Expected type: t2 -> t0 -> t1 Actual type: (t2 -> t0 -> t1) -> t0 -> t1 In the first argument of `x', namely `x' In the first argument of `f', namely `(x x)' In the expression: f (x x) a <interactive>:10:57: Occurs check: cannot construct the infinite type: t2 = t2 -> t0 -> t1 In the first argument of `x', namely `x' In the first argument of `f', namely `(x x)' In the expression: f (x x) a (0.01 secs, 1033328 bytes) The same limitation exists in Ocaml: utop # let fix f g = (fun x a -> f (x x) a) (fun x a -> f (x x) a) g;; Error: This expression has type 'a -> 'b but an expression was expected of type 'a The type variable 'a occurs inside 'a -> 'b However, in Ocaml, one can allow recursive types by passing in the -rectypes switch: -rectypes Allow arbitrary recursive types during type-checking. By default, only recursive types where the recursion goes through an object type are supported. By using -rectypes, everything works: utop # let fix f g = (fun x a -> f (x x) a) (fun x a -> f (x x) a) g;; val fix : (('a -> 'b) -> 'a -> 'b) -> 'a -> 'b = <fun> utop # let fact_improver partial n = if n = 0 then 1 else n*partial (n-1);; val fact_improver : (int -> int) -> int -> int = <fun> utop # (fix fact_improver) 5;; - : int = 120 Being curious about type systems and type inference, this raises some questions I'm still not able to answer. First, how does the type checker come up with the type t2 = t2 -> t0 -> t1? Having come up with that type, I guess the problem is that the type (t2) refers to itself on the right side? Second, and perhaps most interesting, what is the reason for the Haskell/Ocaml type systems to disallow this? I guess there is a good reason since Ocaml also will not allow it by default even if it can deal with recursive types if given the -rectypes switch. If these are really big topics, I'd appreciate pointers to relevant literature. [1] http://rosettacode.org/wiki/Y_combinator#Haskell

• What is the most platform- and Python-version-independent way to make a fast loop for use in Python?

  - by Statto

  I'm writing a scientific application in Python with a very processor-intensive loop at its core. I would like to optimise this as far as possible, at minimum inconvenience to end users, who will probably use it as an uncompiled collection of Python scripts, and will be using Windows, Mac, and (mainly Ubuntu) Linux. It is currently written in Python with a dash of NumPy, and I've included the code below. Is there a solution which would be reasonably fast which would not require compilation? This would seem to be the easiest way to maintain platform-independence. If using something like Pyrex, which does require compilation, is there an easy way to bundle many modules and have Python choose between them depending on detected OS and Python version? Is there an easy way to build the collection of modules without needing access to every system with every version of Python? Does one method lend itself particularly to multi-processor optimisation? (If you're interested, the loop is to calculate the magnetic field at a given point inside a crystal by adding together the contributions of a large number of nearby magnetic ions, treated as tiny bar magnets. Basically, a massive sum of these.) # calculate_dipole # ------------------------- # calculate_dipole works out the dipole field at a given point within the crystal unit cell # --- # INPUT # mu = position at which to calculate the dipole field # r_i = array of atomic positions # mom_i = corresponding array of magnetic moments # --- # OUTPUT # B = the B-field at this point def calculate_dipole(mu, r_i, mom_i): relative = mu - r_i r_unit = unit_vectors(relative) #4pi / mu0 (at the front of the dipole eqn) A = 1e-7 #initalise dipole field B = zeros(3,float) for i in range(len(relative)): #work out the dipole field and add it to the estimate so far B += A*(3*dot(mom_i[i],r_unit[i])*r_unit[i] - mom_i[i]) / sqrt(dot(relative[i],relative[i]))**3 return B

• How to generate random numbers of lognormal distribution within specific range in Matlab

  - by Harpreet

  My grain sizes are defined as D=[1.19,1.00,0.84,0.71,0.59,0.50,0.42]. The problem is described below in steps. Grain sizes should follow lognormal distribution. The mean of the grain sizes is fixed as 0.84 and the standard deviation should be as low as possible but not zero. 90% of the grains (by weight %) fall in the size range of 1.19 to 0.59, and the rest 10% fall in size range of 0.50 to 0.42. Now I want to find the probabilities (weight percentage) of the grains falling in each grain size. It is allowable to split this grain size distribution into further small sizes but it must always be in the range of 1.19 and 0.42, i.e. 'D' can be continuous but 0.42 < D < 1.19. I need it fast. I tried on my own but I am not able to get the correct result. I am getting negative probabilities (weight percentages). Thanks to anyone who helps. I didn't incorporate the point 3 as I came to know about that condition later. Here are simple steps I tried: %% D=[1.19,1.00,0.84,0.71,0.59,0.50,0.42]; s=0.30; % std dev of the lognormal distribution m=0.84; % mean of the lognormal distribution mu=log(m^2/sqrt(s^2+m^2)); % mean of the associated normal dist. sigma=sqrt(log((s^2/m^2)+1)); % std dev of the associated normal dist. [r,c]=size(D); for i=1:c D(i)=mu+(sigma.*randn(1)); w(i)=(log(D(i))-mu)/sigma; % the probability or the wt. percentage of the grain sizes end grain_size=exp(D); %%

• Form values appear blank when submitting to the database - Drupal FormAPI

  - by GaxZE

  Hello, I have been working on this drupal form API script for past week and half. to give an insight into my problem.. the form below merely lists a host of database records which contain 5 individual scoring ranks. (mind, action, relationship, language and IT). this code is apart of my own custom module where all values are listed from the database. the idea behind this module is to be able to edit these values on a large scale. I am having trouble getting the values entered in the form to be passed to the variables inside of the marli_admin_submit function. the second problem is the assigning those values to their specific ID. for this purpose id like to add im merely trying to get just one score updated rather than all of them. below is my code. any advice appreciated. function marli_scores(){ $result = pager_query(db_rewrite_sql('SELECT * FROM marli WHERE value != " "')); while ($node = db_fetch_object($result)) { $attribute = $node->attribute; $field = $node->field_name; $item = $node->value; $mind = $node->mind; $action = $node->action; $relationship = $node->relationship; $language = $node->language; $it = $node->it; $form['field'][$node->marli_id] = array('#type' => 'markup', '#value' => $field, '#prefix' => '<b>', '#suffix' => '</b>'); $form['title'][$node->marli_id] = array('#type' => 'markup', '#value' => $item, '#prefix' => '<b>', '#suffix' => '</b>'); $form['mind'][$node->marli_id] = array('#type' => 'textfield', '#maxlength' => '1', '#size' => '1', '#value' => $mind); $form['action'][$node->marli_id] = array('#type' => 'textfield', '#maxlength' => '1', '#size' => '1', '#value' => $action); $form['relationship'][$node->marli_id] = array('#type' => 'textfield', '#maxlength' => '1', '#size' => '1', '#value' => $relationship); $form['language'][$node->marli_id] = array('#type' => 'textfield', '#maxlength' => '1', '#size' => '1', '#value' => $language); $form['it'][$node->marli_id] = array('#type' => 'textfield', '#maxlength' => '1', '#size' => '1', '#value' => $it); } $form['pager'] = array('#value' => theme('pager', NULL, 50, 0)); $form['save'] = array('#type' => 'submit', '#value' => t('Save')); $form['#theme'] = 'marli_scores'; return $form; } function marli_admin_submit($form, &$form_state) { $marli_id = 4; $submit_mind = $form_state['values']['mind'][$marli_id]; $submit_action = $form_state['values']['action'][$marli_id]; $submit_relationship = $form_state['values']['relationship'][$marli_id]; $submit_language = $form_state['values']['language'][$marli_id]; $submit_it = $form_state['values']['it'][$marli_id]; $sql_query = "UPDATE {marli} SET mind = %d, action = %d, relationship = %d, language = %d, it = %d WHERE marli_id = %d"; if ($success = db_query($sql_query, $submit_mind, $submit_action, $submit_relationship, $submit_language, $submit_it)) { drupal_set_message(t(' Values have been saved.')); } else { drupal_set_message(t('There was an error saving your data. Please try again.')); } }

• Simple tips to design a Customer Journey Map

  - by Isabel F. Peñuelas

  “A model can abstract to a level that is comprehensible to humans, without getting lost in details.” -The Unified Modeling Language Reference Manual. Inception using Post-it, StoryBoards, Lego or Mindmaping Techniques The first step in a Customer Experience project is to describe customer interactions creating a customer journey map. Modeling is never easy, so to succeed on this effort, it is very convenient that your CX´s team have some “abstract thinking” skills. Besides is very helpful to consult a Business Service Design offered by an Interactive Agency to lead your inception process. Initially, you may start by a free discussion using post-it cards; storyboards; even lego or any other brainstorming technique you like. This will help you to get your mind into the path followed by the customer to purchase your product or to consume any business service you actually offer to your customers, or plan to offer in the near future. (from www.servicedesigntools.org) Colorful Mind Maps are very useful to document and share meeting ideas. Some Mind Maps software providers as ThinkBuzzan provide trial versions, and you will find more mindmapping options on this post by Mashable. Finally to produce a quick one, I do recommend Wise, an entirely online mindmaping service. On my view the best results in terms of communication will always come for an artistic hand-made drawing. Customer Experience Mind Map Example Making your first Customer Journey Map To add some more formalization to your thoughts, there is a wide offering for designing Customer Journey Maps. A Customer Map can be represented as an oriented graph in which another follows each step. The one below is the most simple Customer Journey you can draw. Nothing more than a couple of pictures, numbers and lines to design the customer steps sequence in the purchase process. Very simple Customer Journey for Social Mobile Shopping There are a lot of Customer Journey templates much more sophisticated available  in the Web using a variety of styles, as per example this one with a focus on underlining emotional experience, or this other worksheet template. Representing different interaction devices on the vertical axis, and touchpoints / requirements and existing gaps horizontally  is today´s most common format for Customer Journeys. From Customer Journey Maps to CX Technology Adoption Plans Once you have your map ready, you can start to identify the IT infrastructure requirements for your CXProject. By analyzing customer problems and improvement opportunities with maps, you will then identify the technology gaps and the new investment requirements in your IT infrastructure. Deeping step by step from the more abstract to the more concrete is the best guarantee to take the right IT investment decisions.  ¡Remember to keep your initial customer journey safe on your pocket in every one of your CX´s project meetings- that´s you map to success!

• What are the basic features of an email module in a common web application?

  - by Coral Doe

  When developing an email module, what are the features to have in mind, besides actual email sending? I am talking about an email module that notifies users of events and periodically sends reports. The only other feature I have in mind is maintaining grey/black lists for users that do illegal operations in the system or any other things that may lead to email/domain/IP banning. Is there an etiquette for developing email modules? Are there some references of requirements for such modules?

• Oracle Enterprise Cloud Summit Egerszalókon

  - by Lajos Sárecz

  2011 március 30-án a HOUG konferencia keretében tartjuk az Oracle Enterprise Cloud Summit konferenciát. A konferencia programja a HOUG programjába illeszkedik, megtalálható a HOUG konferencia weboldalán. Igyekszünk teljes áttekintést adni arról, az Oracle milyen technológiákkal támogatja akár a publikus, akár a privát felhok kialakítását. Érdemes már most regisztrálni, a mai nap még kedvezményesen lehet megtenni. Azt gondolom, mind a konferencia helyszínét biztosító Saliris Resort Spa & Konferencia Hotel, mind a konferencia programja indokolja a részvételt, remélem sok olvasómmal találkozhatok ott személyesen is.
