• Adding up row number and displaying total using COUNT (PHP MySQL)

  - by Yvonne

  I'm attempting to run a query that adds up the total number of subjects in a class. A class has many subjects. There is a 'teachersclasses' table between teachers (the user table) and classes. The principles sounds pretty simple but I'm having some trouble in getting my page to display the number of subjects for each class (directly associated with the teacher) This is what I have so far, trying to make use of the COUNT with a nested SELECT: SELECT (SELECT count(*) FROM subjects WHERE subjects.classid = class.classid) AS total_subjects, class.classname, class.classid FROM class Then I am calling up 'num_subjects' to present the total within a while loop: <?php echo $row['total_subjects']?> From the above, I am receiving the total subjects for a class, but within the same table row (for one class) and my other while loop doesnt run anymore, which returns all of the classes associated with a teacher :( ... Bit of a mess now! I know to return the classes for a particular teacher, I can do an additional WHERE clause on the session of 'teacherid' but I think my query is getting too complicated for me that errors are popping up everywhere. Anyone have a quick fix for this! Thanks very much

• Select form children when multiple forms are present jQuery

  - by afreeland

  I am dealing with a webpage that has multiple forms..some basic HTML forms and some AJAX forms. I have a created validation for inputs, let me give an example...if an input has a class="required" whenever a submit button is pressed if any required classes are empty then the form doesnt submit. Which works great...until you have multiple forms with required fields that dont apply to the section your submitting. I am able to find the closest form $(this).closest("form") and it gets me the form element properly, I then need to be able to loop only through the children of that form. I have tried: .children(':input'), .find('input') and honestly to many to list. Here is the code for when a button is selected $('#formSubmit').click(function (e) { var submit = true; var form = $(this).closest("form"); var formID = $(form).attr("id"); e.preventDefault(); $(form).children(":input").each(function () { if ($('#ERROR').length > 0) { submit = false; alert("Please fix errors to continue"); } $('.required').each(function () { if ($(this).val() == "" || $(this).val() == undefined) { submit = false; $(this).css({ 'background-color': '#fef236' }); } }); }); if (submit == true) { this.form.submit(); } }); //End of #formSubmit Also of interest I have started creating forms with ids that are GUID's so they will be unique and allow me to target things without any issues, just wanted to throw that out there if it can help lead to a solution I appreciate any help =)

• Shell halts while looping and 'transforming' values in dictionary (Python 2.7.5)

  - by Gus

  I'm building a program that will sum digits in a given list in a recursive way. Say, if the source list has 10 elements, the second list will have 9, the third 8 and so on until the last list that will have only one element. This is done by adding the first element to the second, then the second to the third and so on. I'm stuck without feedback from the shell. It halts without throwing any errors, then in a couple of seconds the fan is spinning like crazy. I've read quite a few posts here and changed my approach, but I'm not sure that what have so far can produce the results I'm looking for. Thanks in advance: #--------------------------------------------------- #functions #--------------------------------------------------- #sum up pairs in a list def reduce(inputList): i = 0 while (i < len(inputList)): #ref to current and next item j = i + 1 #don't go for the last item if j != len(inputList): #new number eq current + next number newNumber = inputList[i] + inputList[j] if newNumber >= 10: #reduce newNumber to single digit newNumber = sum(map(int, str(newNumber))) #collect into temp list outputList.append(newNumber) i = i + 1 return outputList; #--------------------------------------------------- #program starts here #--------------------------------------------------- outputList = [] sourceList = [7, 3, 1, 2, 1, 4, 6] counter = len(sourceList) dict = {} dict[0] = sourceList print '-------------' print 'Level 0:', dict[0] for i in range(counter): j = i + 1 if j != counter: baseList = dict.get(i) #check function to understand what it does newList = reduce(baseList) #new key and value from previous/transformed value dict[j] = newList print 'Level %d: %s' % (j, dict[j])

• error: 'void Base::output()' is protected within this context

  - by Bill

  I'm confused about the errors generated by the following code. In Derived::doStuff, I can access Base::output directly by calling it. Why can't I create a pointer to output() in the same context that I can call output()? (I thought protected / private governed whether you could use a name in a specific context, but apparently that is incomplete?) Is my fix of writing callback(this, &Derived::output); instead of callback(this, Base::output) the correct solution? #include <iostream> using std::cout; using std::endl; template <typename T, typename U> void callback(T obj, U func) { ((obj)->*(func))(); } class Base { protected: void output() { cout << "Base::output" << endl; } }; class Derived : public Base { public: void doStuff() { // call it directly: output(); Base::output(); // create a pointer to it: // void (Base::*basePointer)() = &Base::output; // error: 'void Base::output()' is protected within this context void (Derived::*derivedPointer)() = &Derived::output; // call a function passing the pointer: // callback(this, &Base::output); // error: 'void Base::output()' is protected within this context callback(this, &Derived::output); } }; int main() { Derived d; d.doStuff(); }

• SQL query doesn't get inserted

  - by Deejdd

  I've been trying to get my query to work for some time it runs but doesn't insert anything nor does it return any errors. The database connection is open and is successfuly connection. The Table is called errorlog and holds the following data - id (int autoincremental, Primary key, Unique) - exception (varchar) - time (DateTime) exception = String(error message) time = DateTime.Now Here's the code: public void insertError(string error, DateTime time) { SqlCeParameter[] sqlParams = new SqlCeParameter[] { new SqlCeParameter("@exception", error), new SqlCeParameter("@time", time) }; try { cmd = new SqlCeCommand(); cmd.Connection = connection; cmd.CommandType = CommandType.Text; cmd.CommandText = "INSERT INTO errorlog (exception, time) VALUES(@exception, @time)"; cmd.Parameters.AddRange(sqlParams); cmd.ExecuteNonQuery(); } catch (Exception e) { Console.WriteLine(e.Message); } } Any help would be appreciated, Thanks in advance. EDIT Removed quotes around @exception Heres the connection: protected DataController() { try { string appPath = System.IO.Path.GetDirectoryName(Assembly.GetAssembly(typeof(DataController)).CodeBase).Replace(@"file:\", "") + @"\"; string strCon = @"Data Source = " + appPath + @"Data\EasyShop.sdf"; connection = new SqlCeConnection(strCon); } catch (Exception e) { } connection.Open(); } Finally the way it gets called: public bool log(string msg, bool timestamp = true) { DataController dc = DataController.Instance(); dc.insertError(msg, DateTime.Today); return true; }

• Struct arrays in C

  - by ThomasTheTankEngine

  Hi I'm having trouble trying to initializing each element of the struct array. When I try and assign the value ZERO to both 'bSize' and 'msgs', it doesn't work as it errors out when i get to malloc. In the printf statement it prints a -1852803823 number. Excuse the messy code as i'm playing around trying to figure it out. struct message{ int *data; int bSize; int msgs; }; int main(int argc, char *argv[]) { ..... } void getSchedFile (FILE *file, int **schd) { struct message sMsg[nodeCount]; const int pakSize = 6; // Iniitialise message buffer for (int i=0; i<nodeCount; i++){ sMsg[i].bSize = 0; sMsg[i].msgs = 0; printf("bSize %d\n",sMsg[i].bSize); } /* Get the number of bytes */ fseek(file, 0L, SEEK_SET); int time; while((fscanf(file, "%d", &time)) != EOF){ int src; fscanf(file, "%d", &src); // get source node id // These are here for easier reading code int aPos = sMsg[src].bSize; int nMsg = sMsg[src].msgs; printf("size %d\n", sMsg[src].bSize); if (sMsg[src].bSize==0){ sMsg[src].data = malloc( pakSize * sizeof(int)); }else{ sMsg[src].data = realloc(sMsg[src].data, (aPos+pakSize)*sizeof(int)); }

• Simple syntax question

  - by stabby

  Hey everyone, First off, sorry for my noob-ness. Believe me when i say ive been rtfm'ing. Im not lazy, im just dumb (apparently). On the bright side, this could earn someone some easy points here. I'm trying to do a match/replace with a pattern that contains special characters, and running into syntax errors in a Flex 3 app. I just want the following regex to compile... (while also replacing html tags with "") value.replace(/</?\w+((\s+\w+(\s*=\s*(?:".*?"|'.*?'|[^'">\s]+))?)+\s*|\s*)/?>/g, ""); On a side note, the pattern /<.*?/g wouldn't work in cases where there are html entities between tags, like so: <TEXTFORMAT LEADING="2"> <P ALIGN="LEFT"> <FONT FACE="Arial" SIZE="11" COLOR="#4F4A4A" LETTERSPACING="0" KERNING="0"><one</FONT> </P> </TEXTFORMAT><TEXTFORMAT LEADING="2"> <P ALIGN="LEFT"> <FONT FACE="Arial" SIZE="11" COLOR="#4F4A4A" LETTERSPACING="0" KERNING="0">two</FONT> </P> </TEXTFORMAT> The first regex would get both "<one" and "two", but the second would only get "hi" Thanks!

• Conditional fieldgroups/fieldsets in Drupal 7

  - by seane

  Background: In Drupal 7, I have created a form with CCK (aka the Field UI). I used the Field group module to create a fieldgroup, but I need it to be conditional, meaning it will only display depending on a previous answer. Previous research: To create a conditional field, you can use hook_form_alter() to edit the #states attribute like so: function MYMODULE_form_alter(&$form, &$form_state, $form_id) { if ($form_id == 'person_info_node_form') { // Display 'field_maiden_name' only if married $form['field_maiden_name']['#states'] = array( 'visible' => array( ':input[name="field_married[und]"]' => array('value' => 'Yes'), ), ); } } However, there seems to be no way to use the States API for fieldgroups. One thing to note is that, while fields are stored in $form, fieldgroups are stored in $form['#groups'] as well as in $form['#fieldgroups']. I don't know how to distinguish between these, and with this in mind, I have tried to apply a #states attribute to a fieldgroup in the same manner as above. However, it only produces server errors. Question: Is there a way to make a fieldgroup display conditionally using the States API or some alternative approach?

• Wordpress curl save Images

  - by Jeton Ramadani

  I am working on saving images from external sites into a folder in my wordpress theme. And I was wondering if its Ok to call curl twice or can it be done with one time. Example: $data = get_url('http://www.veoh.com/watch/v19935546Y8hZPgbZ'); // getting the url first curl instance preg_match('/fullHighResImagePath="(.*?)"/', $data, $thumbnail); // find the image from content savePhoto($thumbnail, $post->ID); //2nd instance of curl to save the image function get_url($url) { $user_agent = "Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.2)"; $ytc = curl_init(); // initialize curl handle curl_setopt($ytc, CURLOPT_URL, $url); // set url to post to curl_setopt($ytc, CURLOPT_FAILONERROR, 1); // Fail on errors curl_setopt($ytc, CURLOPT_FOLLOWLOCATION, 1); // allow redirects curl_setopt($ytc, CURLOPT_RETURNTRANSFER, 1); // return into a variable curl_setopt($ytc, CURLOPT_PORT, 80); //Set the port number curl_setopt($ytc, CURLOPT_TIMEOUT, 15); // times out after 15s curl_setopt($ytc, CURLOPT_HEADER, 1); // include HTTP headers curl_setopt($ytc, CURLOPT_USERAGENT, $user_agent); $source = curl_exec($ytc); curl_close($ytc); $data = trim( $source ); return $data; } function savePhoto($remoteImage, $isbn) { $ch = curl_init(); curl_setopt ($ch, CURLOPT_URL, $remoteImage); curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, 0); $fileContents = curl_exec($ch); curl_close($ch); if (DIRECTORY_SEPARATOR=='/'){ $absolute_path = dirname(__FILE__).'/'; } else { $absolute_path = str_replace('\\', '/', dirname(__FILE__)).'/'; } $newImg = imagecreatefromstring($fileContents); return imagejpeg($newImg, $absolute_path ."video_images/{$isbn}.jpg",100); }

• is it good "form" to declare new classes in the same file ?

  - by hatorade

  I code in Python a lot, and I frequently create classes. Now, I'm not sure if this is good Python form, but I just declare a class in the same file as my main(). class foo { ... } I'm wondering if it's good form in Java to do the same? For example, class foo { public static int name; public static int numPoints; public static int[] points; } public class bar { public static void main(String[] args) { ... } } Does not throw errors in Eclipse, so it must be allowed. But is it okay to do? Would it be better to just declare this class in a separate file..? Edit: I just want to emphasize that my new class literally is just a container to hold the same type of data multiple times, and literally will only have like 3 values. So it's total about 5 lines of code. The question is - does this merit a new file?

• Create rails record from two ids

  - by Michael Luby

  The functionality I'm trying to build allows Users to Visit a Restaurant. I have Users, Locations, and Restaurants models. Locations have many Restaurants. I've created a Visits model with user_id and restaurant_id attributes, and a visits_controller with create and destroy methods. Thing is, I can't create an actual Visit record. Any thoughts on how I can accomplish this? Or am I going about it the wrong way. Here's the code: Model: class Visit < ActiveRecord::Base attr_accessible :restaurant_id, :user_id belongs_to :user belongs_to :restaurant end View: <% @restaurants.each do |restaurant| %> <%= link_to 'Visit', location_restaurant_visits_path(current_user.id, restaurant.id), method: :create %> <% @visit = Visit.find_by_user_id_and_restaurant_id(current_user.id, restaurant.id) %> <%= @visit != nil ? "true" : "false" %> <% end %> Controller: class VisitsController < ApplicationController before_filter :find_restaurant before_filter :find_user def create @visit = Visit.create(params[:user_id => @user.id, :restaurant_id => @restaurant.id]) respond_to do |format| if @visit.save format.html { redirect_to location_restaurants_path(@location), notice: 'Visit created.' } format.json { render json: @visit, status: :created, location: @visit } else format.html { render action: "new" } format.json { render json: @visit.errors, status: :unprocessable_entity } end end end def destroy @visit = Visit.find(params[:user_id => @user.id, :restaurant_id => @restaurant.id]) @restaurant.destroy respond_to do |format| format.html { redirect_to location_restaurants_path(@restaurant.location_id), notice: 'Unvisited.' } format.json { head :no_content } end end private def find_restaurant @restaurant = Restaurant.find(params[:restaurant_id]) end def find_user @user = current_user end end

• jQuery validation plugin: valid() does not work with remote validation ?

  - by a-dilla

  I got started by following this awesome tutorial, but wanted to do the validation on on keyup and place my errors somewhere else. The remote validation shows its own error message at the appropriate times, making me think I had it working. But if I ask specifically if a field with remote validation is valid, it says no, actually, its not. In application.js I have this... $("#new_user").validate({ rules: { "user[login]": {required: true, minlength: 3, remote: "/live_validations/check_login"}, }, messages: { "user[login]": {required: " ", minlength: " ", remote: " "}, } }); $("#user_login").keyup(function(){ if($(this).valid()){ $(this).siblings(".feedback").html("0"); }else{ $(this).siblings(".feedback").html("1"); } }) And then this in the rails app... def check_login @user = User.find_by_login(params[:user][:login]) respond_to do |format| format.json { render :json => @user ? "false" : "true" } end end I think that my problem might have everything to do with this ticket over at jQuery, and tried to implement that code, but, being new to jQuery, it's all a bit over my head. When I say bit, I mean way way. Any ideas to fix it, or a new way to look at it, would be a big help.

• C# Basic Multi-Threading Question: Call Method on Thread A from Thread B (Thread B started from Thre

  - by Nick

  What is the best way to accomplish this: The main thread (Thread A) creates two other threads (Thread B and Thread C). Threads B and C do heavy disk I/O and eventually need to pass in resources they created to Thread A to then call a method in an external DLL file which requires the thread that created it to be called correctly so only Thread A can call it. The only other time I ever used threads was in a Windows Forms application, and the invoke methods were just what I needed. This program does not use Windows Forms, and as such there are no Control.Invoke methods to use. I have noticed in my testing that if a variable is created in Thread A, I have no trouble accessing and modifying it from Thread B/C which seems very wrong to me. With Winforms, I was sure it threw errors for trying to access things created on other threads. I know it is unsafe to change things from multiple threads, but I really hoped .NET would forbid it altogether to ensure safe coding. Does .NET do this, and I am just missing the boat, or does it only do it with WinForm apps? Since it does seemingly allow this, do I do something like an OS would do, create a flag and monitor it from Thread A to see if it changes. If it does, then call the method. Doesnt the event handler essentially do this, so could an event be used somehow called on the main thread?

• Rails form not creating object

  - by user2136807

  I have created a simple form to create an instance of a modle and for some reason it is not calling the create method in the controller. Here is the form code: <% @house.mates.each do |mate| %> <p><%= mate.name %></p> <% end %> <h2>Add a new mate:</h2> <%= form_for @mate do |f| %> <p><%= f.label "Name" %> <%= f.text_field :name %> <%= f.hidden_field :house_id %> </p> <%= f.submit "Submit", :action => :create %> <% end %> Here is the controller code: class MatesController < ApplicationController def new @mate = Mate.new end def create @mate = Mate.new(params[:mate]) @mate.save redirect_to house_path(current_house) end end There is a many to one relationship between the Mate model and the House model... I am fairly new to rails but I have made other apps with similar forms, and I have never had this problem before. I can create and save Mate objects in the console, and I am not getting any errors, so it seem that somehow the controller method is not being called. Any help is much appreciated!

• Aborting $.post() / responsive search results

  - by Emphram Stavanger

  I have the following kludgey code; HTML <input type="search" id="search_box" /> <div id="search_results"></div> JS var search_timeout, search_xhr; $("#search_box").bind("textchange", function(){ clearTimeout(search_timeout); search_xhr.abort(); search_term = $(this).val(); search_results = $("#search_results"); if(search_term == "") { if(search_results.is(":visible")) search_results.stop().hide("blind", 200); } else { if(search_results.is(":hidden")) search_results.stop().show("blind", 200); } search_timeout = setTimeout(function () { search_xhr = $.post("search.php", { q: search_term }, function(data){ search_results.html(data); }); }, 100); }); (uses the textchange plugin by Zurb) The problem I had with my original more simple code was that it was horribly unresponsive. Results would appear seconds later, especially when typed slower, or when Backspace was used, etc. I made all this, and the situation isn't much better. Requests pile up. My original intention is to use .abort() to cancel out whatever previous request is still running as the textchange event is fired again (as per 446594). This doesn't work, as I get repeated errors like this in console; Uncaught TypeError: Cannot call method 'abort' of undefined How can I make .abort() work in my case? Furthermore, is this approach the best way to fetch 'realtime' search results? Much like Facebook's search bar, which gives results as the user types, and seems to be very quick on its feet.

• Desperate help using PHP's $_SERVER["DOCUMENT_ROOT"] on a web server?

  - by Nickersoft

  I've spent the past few months building a website on localhost. Throughout the site, instead of using relative paths, I used $_SERVER["DOCUMENT_ROOT"] to access the root of my server so I could reference files from there. However, I just decided to upload my site to 000webhost. As I soon found out, and for those of you who use them, you are probably aware, that their server root is different than your actual directory in which you upload your files. I believe it's virtual hosting... anyway, my $_SERVER["DOCUMENT_ROOT"] now throws errors along the lines of this on the site: Warning: include_once() [function.include-once]: open_basedir restriction in effect. File(/usr/local/apache/htdocs/mypath) is not within the allowed path(s) Every other site I looked at said that you should just replace $_SERVER["DOCUMENT_ROOT"] with the home directory provided to you by 000webhost. However, if I want to change hosting services in the future, I'm screwed. Is there any way to use $_SERVER to access a set virtual directory or use htaccess or something to make my code work? I tried using DocumentRoot in a htaccess file in my root directory, but it threw a 404 error when trying to access the page. I'm in desperate need... can anyone help me?

• SQL SERVER – What is Spatial Database? – Developing with SQL Server Spatial and Deep Dive into Spati

  - by pinaldave

  What is Spatial Database? A spatial database is a database that is optimized to store and query data related to objects in space, including points, lines and polygons. While typical databases can understand various numeric and character types of data, additional functionality needs to be added for databases to process spatial data types. (Source: Wikipedia) Today I will be talking about the same subject at Microsoft TechEd India. If you want to learn about how to spatial aspect of data and how to integrate them with SQL Server this is the perfect session for you. Spatial is very special concept of SQL Server and I really like how it is implemented in SQL Server. In general Performance Tuning and Query Optimization is something I always have enjoyed in my professional life. Index are my best friends and many time, by implementing and many time by removing I have improved the performance of the system. In this session, I will be talking about Index along with Spatial Data. As Spatial Database is very interesting concept, I will cover super short but very interesting 10 quick slides about this subject. I will make sure in very first 20 mins, you will understand following topics Introduction to Spatial Database One line definition Understanding Spatial Indexing Index Internals Query/Performance Tuning Query Hinting/Cost Analysis Spatial Index Catalog Views Performance Troubleshooting Finding Optimal Index using Spatial Index SP Common Errors Index Maintenance This slides decks will be followed by around 30 mins demo which will have story of geometry, geography, index internals and performance tuning. If you are interested in learning how GIS works and how SQL Server out of the box supports this wonderful tools, you will really like how the story is told. I am sure all people who attend the event will know how the Bangalore is positioned on the map of India. I will take example of Bangalore and Hyderabad and demonstrate how index can improve the performance. Well there are lots of story to tell in the session, and I will be opening this session with the beautiful script of Botticelli’s Birth of Venus created by Michael J. Swart. I will also demonstrate few real life scenario where I will be talking about Spatial Database and its usage. Do not miss this session. At the end of session there will be book awarded to best participant. My session details: Session 3: Developing with SQL Server Spatial and Deep Dive into Spatial Indexing Date: April 14, 2010 Time: 5:00pm-6:00pm Microsoft SQL Server 2008 delivers new spatial data types that enable you to consume, use, and extend location-based data through spatial-enabled applications. Attend this session to learn how to use spatial functionality in next version of SQL Server to build and optimize spatial queries. This session outlines the new geography data type to store geodetic spatial data and perform operations on it, use the new geometry data type to store planar spatial data and perform operations on it, take advantage of new spatial indexes for high performance queries, use the new spatial results tab to quickly and easily view spatial query results directly from within Management Studio, extend spatial data capabilities by building or integrating location-enabled applications through support for spatial standards and specifications and much more.

• Screen Scraping Twitter

  - by BRADINO

  I got an email today asking for help to scrape Twitter. In particular, to be able to login. So I am going to show everyone, NOT to encourage anyone to violate Twitters terms of use but as an educational blog post about how PHP and cURL can be used to post variables and store cookies. Again, I am using the cScrape class I wrote, which you can download. Step 1 First go to twitter.com and look at the source code of the login to get the form field names and the form post location. You will see that the form posts to https://twitter.com/session and the username and password fields are session[username_or_email] and session[password] respectively. Step 2 Now you are ready to login. So using the fetch function in the Scrape class you create an associative array to contain the form values you want to post. The other thing you will need to do is uncomment the lines for CURLOPT_COOKIEFILE and CURLOPT_COOKIEJAR. Cookies will be required to stay logged in and scrape around. The paths to the cookie files need to be writable by your app. Also you will need to uncomment the line about CURLOPT_FOLLOWLOCATION. $data = array('session[username_or_email]' => "bradino", 'session[password]' => "secret"); $scrape->fetch('https://twitter.com/sessions',$data); Step 1.5 Oops that didn't work. All I got back was 403 Forbidden: The server understood the request, but is refusing to fulfill it. Ahhh I see another variable called authenticity_token I bet Twitter was looking for that. So let's back up and first hit twitter.com to get the authenticity_token variable, and then make the login post request with that variable included in our array of parameters. $scrape->fetch('https://twitter.com'); $data = array('session[username_or_email]' => "bradino", 'session[password]' => "secret"); $data['authenticity_token'] = $scrape->fetchBetween('name="authenticity_token" type="hidden" value="','"',$scrape->result); $scrape->fetch('https://twitter.com/sessions',$data); echo $scrape->result; So that's basically it. Now you are logged in and can scrape around and request other pages as you normally would. Sorry it wasn't a longer post. I really do enjoy this kind of stuff so if anyone has a request, hit me up. Errors? 1) Make sure that you are properly parsing the token variable 2) Make sure that you uncommented the lines about CURLOPT_COOKIEFILE and CURLOPT_COOKIEJAR, those options need to be enabled and be sure the path set is writable by your application 3) Make sure that the path to the cookie file is writable and that it is getting data written to it 4) If you get a message about being redirected you need to uncomment the line about CURLOPT_FOLLOWLOCATION, that option needs to be enabled true

• Raspberry Pi entrance signed backed by Umbraco - Part 1

  - by Chris Houston

  Being experts on all things Umbraco, we jumped at the chance to help our client, QV Offices, with their pressing signage predicament. They needed to display a sign in the entrance to their building and approached us for our advice. Of course it had to be electronic: displaying multiple names of their serviced office clients, meeting room bookings and on-the-pulse promotions. But with a winding Victorian staircase and minimal storage space how could the monitor be run, updated and managed? That’s where we came in…Raspberry PiUmbraco CMSAutomatic updatesAutomated monitor of the signPower saving when the screen is not in useMounting the screenThe screen that has been used is a standard LED low energy Full HD screen and has been mounted on the wall using it's VESA mounting points, as the wall is a stud wall we were able to add an access panel behind the screen to feed through the mains, HDMI and sensor cables.The Raspberry Pi is then tucked away out of sight in the main electrical cupboard which just happens to be next to the sign, we had an electrician add a power point inside this cupboard to allow us to power the screen and the Raspberry Pi.Designing the interface and editing the contentAlthough a room sign was the initial requirement from QV Offices, their medium term goal has always been to add online meeting booking to their website and hence we suggested adding information about the current and next day's meetings to the sign that would be pulled directly from their online booking system.We produced the design and built the web page to fit exactly on a 1920 x 1080 screen (Full HD in Portrait)As you would expect all the information can be edited via an Umbraco CMS, they are able to add floors, rooms, clients and virtual clients as well as add meeting bookings to their meeting diary.How we configured the Raspberry PiAfter receiving a new Raspberry Pi we downloaded the latest release of Raspbian operating system and followed the official guide which shows how to copy the OS onto an SD card from a Mac, we then followed the majority of steps on this useful guide: 10 Things to Do After Buying a Raspberry Pi.Installing ChromiumWe chose to use the Chromium web browser which for those who do not know is the open sourced version of Google Chrome. You can install this from the terminal with the following command:sudo apt-get install chromium-browserInstalling UnclutterWe found this little application which automatically hides the mouse pointer, it is used in the script below and is installed using the following command:sudo apt-get install unclutterAuto start Chromium and disabling the screen saver, power saving and mouseWhen the Raspberry Pi has been installed it will not have a keyboard or mouse and hence if their was a power cut we needed it to always boot and re-loaded Chromium with the correct URL.Our preferred command line text editor is Nano and I have assumed you know how to use this editor or will be able to work it out pretty quickly.So using the following command:sudo nano /etc/xdg/lxsession/LXDE/autostartWe then changed the autostart file content to:@lxpanel --profile LXDE@pcmanfm --desktop --profile LXDE@xscreensaver -no-splash@xset s off@xset -dpms@xset s noblank@chromium --kiosk --incognito http://www.qvoffices.com/someURL@unclutter -idle 0The first few commands turn off the screen saver and power saving, we then open Cromium in Kiosk Mode (full screen with no menu etc) and pass in the URL to use (I have changed the URL in this example) We found a useful blog post with the Cromium command line switches.Finally we also open an application called Unclutter which auto hides the mouse after 0 seconds, so you will never see a mouse on the sign.We also had to edit the following file:sudo nano /etc/lightdm/lightdm.confAnd added the following line under the [SeatDefault] section:xserver-command=X -s 0 dpmsRefreshing the screenWe decided to try and add a scheduled task that would trigger Chromium to reload the page, at some point in the future we might well change this to using Javascript to update the content, but for now this works fine.First we installed the XDOTool which enables you to script Keyboard commands:sudo apt-get install xdotoolWe used the Refreshing Chromium Browser by Shell Script post as a reference and created the following shell script (which we called refreshing.sh):export DISPLAY=":0"WID=$(xdotool search --onlyvisible --class chromium|head -1)xdotool windowactivate ${WID}xdotool key ctrl+F5This selects the correct display and then sends a CTRL + F5 to refresh Chromium.You will need to give this file execute permissions:chmod a=rwx refreshing.shNow we have the script file setup we just need to schedule it to call this script periodically which is done by using Crontab, to edit this you use the following command:crontab -eAnd we added the following:*/5 * * * * DISPLAY=":.0" /home/pi/scripts/refreshing.sh >/home/pi/cronlog.log 2>&1This calls our script every 5 minutes to refresh the display and it logs any errors to the cronlog.log file.SummaryQV Offices now have a richer and more manageable booking system than they did before we started, and a great new sign to boot.How could we make sure that the sign was running smoothly downstairs in a busy office centre? A second post will follow outlining exactly how Vizioz enabled QV Offices to monitor their sign simply and remotely, from the comfort of their desks.
