• WCF RIA Services : une approche pragmatique, par Benjamin Devuyst

  Bonjour, J'ai terminé un tutoriel abordant l'utilisation de Wcf Ria Services à travers Silverlight. Ce tutoriel a pour but de décrire les étapes à suivre pour mettre en place RIA, mais en tenant compte de l'expérience acquise au cours de ces derniers mois (réalisation de projets qui utilisent RIA). Il aborde donc la technologie et expose les solutions mises en place pour faciliter les phases de développement (gestion des erreurs, conflits, classe partielle pour définir le "DomainService", etc.). Il s'agit, en quelque sorte, d'ébauches de "bonnes conduites" (en toute modestie) qui ont facilité le développement des logiciels. Le tutoriel est disponible ici :

• How can MySQL be in GDAL's dependencies when it's already installed?

  - by Julien Fouilhé

  I'm trying to install GDAL on my CentOS 64 bits server to be able to make some GIS operations. I tried a simple: # yum install gdal First, the GDAL version is 1.4 (the last released one is 1.9) Then, I see in the dependencies list mysql. But I have mysql already installed, from another repository (remi), with a newer version than the one suggested by yum... Is it a problem of architecture (yum suggests i386)? I risked a yes, but still impossible to install it! Here's the error I have. Transaction Check Error: package mysql-5.5.28-1.el5.remi.x86_64 (which is newer than mysql-5.0.95-1.el5_7.1.i386) is already installed Then, I tried to install it from sources with last version available (1.9.2). I downloaded the GDAL tar.gz, extracted the files and installed it like following: # tar -xzf gdal-1.9.2.tar.gz # ./configure --with-static-proj4=/usr/local/lib --with-threads --with-libtiff=internal --with-geotiff=internal --with-jpeg=internal --with-gif=internal --with-png=internal --with-libz=internal # make # make install But during the make, I have some strange errors displaying, about RegisterOGRMySQL, that I can't understand: chmod a+x gdal-config /bin/sh /home/benjamin/gdal-1.9.2/libtool --mode=link g++ gdalinfo.lo /home/benjamin/gdal-1.9.2/libgdal.la -o gdalinfo libtool: link: g++ .libs/gdalinfo.o -o .libs/gdalinfo /home/benjamin/gdal-1.9.2/.libs/libgdal.so -L/usr/local/lib/lib -L/usr/kerberos/lib64 -lproj -lsqlite3 /usr/lib64/libexpat.so -lpthread -lrt -lcurl -ldl -lgssapi_krb5 -lkrb5 -lk5crypto -lcom_err -lidn -lssl -lcrypto -lz -Wl,-rpath -Wl,/usr/local/lib -Wl,-rpath -Wl,/usr/lib64 /home/benjamin/gdal-1.9.2/.libs/libgdal.so: undefined reference to `RegisterOGRMySQL' collect2: ld returned 1 exit status make[1]: *** [gdalinfo] Error 1 make[1]: Leaving directory `/home/benjamin/gdal-1.9.2/apps' make: *** [apps-target] Error 2 Has anyone a solution?

• Why can't I set boolean columns with update?

  - by Benjamin Oakes

  I'm making a user administration page. For the system I'm creating, users need to be approved. Sometimes, there will be many users to approve, so I'd like to make that easy. I'm storing this as a boolean column called approved. I remembered the Edit Multiple Individually Railscast and thought it would be a great fit. However, I'm running into problems which I traced back to ActiveRecord::Base#update. update works fine in this example: >> User.all.map(&:username) => ["ben", "fred"] >> h = {"1"=>{'username'=>'benjamin'}, "2"=>{"username"=>'frederick'}} => {"1"=>{"username"=>"benjamin"}, "2"=>{"username"=>"frederick"}} >> User.update(h.keys, h.values) => ... >> User.all.map(&:username) => ["benjamin", "frederick"] But not this one: >> User.all.map(&:approved) => [true, nil] >> h = {"1"=>{'approved'=>'1'}, "2"=>{'approved'=>'1'}} >> User.update(h.keys, h.values) => ... >> User.all.map(&:approved) => [true, nil] Chaging from '1' to true didn't make a difference when I tested. What am I doing wrong?

• Editor's Notebook - Social Aura: Insights from the Oracle Social Media Summit

  - by user462779

  Panelists talk social marketing at the Oracle Social Media Summit On November 14, I traveled to Las Vegas for the first-ever Oracle Social Media Summit. The two day event featured an impressive collection of social media luminaries including: David Kirkpatrick (founder and CEO of Techonomy Media and author of The Facebook Effect), John Yi (Head of Marketing Partnerships, Facebook), Matt Dickman (EVP of Social Business Innovation, Weber Shandwick), and Lyndsay Iorio (Social Media & Communications Manager, NBC Sports Group) among others. It was also a great opportunity to talk shop with some of our new Vitrue and Involver colleagues who have been returning great social media results even before their companies were acquired by Oracle. I was live tweeting the event from @OracleProfit which was great for those who wanted to follow along with the proceedings from the comfort of their office or blackjack table. But I've also found over the years that live tweeting an event is a handy way to take notes: I can sift back through my record of what people said or thoughts I had at the time and organize the Twitter messages into some kind of summary account of the proceedings. I've had nearly a month to reflect on the presentations and conversations at the event and a few key topics have emerged: David Kirkpatrick's comment during the opening presentation really set the stage for the conversations that followed. Especially if you are a marketer or publisher, the idea that you are in a one-way broadcast relationship with your audience is a thing of the past. "Rising above the noise" does not mean reaching for a megaphone, ALL CAPS, or exclamation marks. Hype will not motivate social media denizens to do anything but unfollow and tune you out. But knowing your audience, creating quality content and/or offers for them, treating them with respect, and making an authentic effort to please them: that's what I believe is now necessary. And Kirkpatrick's comment early in the day really made the point. Later in the day, our friends @Vitrue demonstrated this point by elaborating on a comment by Facebook's John Yi. If a social strategy is comprised of nothing more than cutting/pasting the same message into different social media properties, you're missing the opportunity to have an actual conversation. That's not shouting at your audience, but it does feel like an empty gesture. Walter Benjamin, perplexed by auraless Twitter messages Not to get too far afield, but 20th century cultural critic Walter Benjamin has a concept that is useful for understanding the dynamics of the empty social media gesture: Aura. In his work The Work of Art in the Age of Mechanical Reproduction, Benjamin struggled to understand the difference he percieved between the value of a hand-made art object (a painting, wood cutting, sculpture, etc.) and a photograph. For Benjamin, aura is similar to the "soul" of an artwork--the intangible essence that is created when an artist picks up a tool and puts creative energy and effort into a work. I'll defer to Wikipedia: "He argues that the "sphere of authenticity is outside the technical" so that the original artwork is independent of the copy, yet through the act of reproduction something is taken from the original by changing its context. He also introduces the idea of the "aura" of a work and its absence in a reproduction." So make sure you put aura into your social interactions. Don't just mechanically reproduce them. Keeping aura in your interactions requires the intervention of an actual human being. That's why @NoahHorton's comment about content curation struck me as incredibly important. Maybe it's just my own prejudice, being in the content curation business myself. And it's not to totally discount machine-aided content management systems, content recommendation engines, and other tech-driven tools for building an exceptional content experience. It's just that without that human interaction--that editor who reviews the analytics and responds to user feedback--interactions over social media feel a bit empty. It is SOCIAL media, right? (We'll leave the conversation about social machines for another day). At the end of the day, experimentation is key. Just like trying to find that right joke to tell at the beginning of your presentation or that good opening like at a cocktail party, social media messages and interactions can take some trial and error. Don't be afraid to try things, tinker with incomplete ideas, abandon things that don't work, and engage in the conversation. And make sure your heart is in it, otherwise your audience can tell. And finally:

• Is It bad for SEO to have internal redirected links? [closed]

  - by Jonas Lindqvist

  I have a large number of pages having similar but not identical content. Example: site.com/dream_dictionary_flying and site.com/dream_interpretation_flying. The problem is that although not being identical, they are sometimes on the edge of being duplicate content. The solution via redirect 301 in htaccess is simple and can be done in a minute, BUT, changing all existing links on the whole site from "/something" to "/something_else" would take ages, it would be thousands of manual changes taking x hundreds of hours. My question is this; is it bad for SEO to have internal links that are redirected, or rather HOW bad is it? For the human user it would not matter at all but from what I have experienced, the search engines don't like it. Is there any rule of thumb here? Please come back with your thoughts and experience on this. Thanks!

• How do I get my programs to communicate with each other

  - by Benjamin Lindqvist

  I'm basically just getting started with programming. The problem I have with progressing is that I have a hard time learning stuff just for the sake of knowing them - I do better when there's a problem to be solved or a task to be completed so I can learn 'on the job'. So I'm interested in starting some interesting project. I know the basics of Python, Java, Matlab and some C++ aswell and I know enough about microcontrollers to make LED blink etc. The type of stuff I'm looking for is for example scraping some weather forecast site (with Python) and outputting the chance of rain to a LCD display, or a program that makes chrome open and log in to facebook if I say "HAL, time for facebook", or more generally, a program that reads serial/USB input, looks for certain sequences and sends instructions to some other program if it finds one. Do you open some kind of shared stream in which one program reads and one writes? What do I need to read up on to do accomplish this myself? I have no experience with linux or the linux terminal, but looking over peoples shoulders makes me suspect that's what people use. Is that correct?

• Firefox : abandon du développement de la version 64 bits pour Windows, trop buggée pour Mozilla

  Firefox : abandon du développement de la version 64 bits Sous Windows, trop buggée pour Mozilla Un des responsables de la Fondation Mozilla en charge de « l'engineering » - Benjamin Smedberg - vient d'appeler à mettre fin au développement de la version 64 bits de Firefox pour Windows. La raison ? Cette déclinaison serait une « source continue d'incompréhension et de frustration » pour les utilisateurs et la communauté. Incompréhension parce que les extensions ne sont que rarement compatibles avec cette version. Frustration, parce que le navigateur serait truffé de bugs inextricables et non corrigés (ce qui, d'après Benjamin Smedberg, ferait que ses utilisateu...

• LCD monitor flicker when connected to a laptop using VGA

  - by Björn Lindqvist

  I have a dual screen setup with two AOC e2450Sw monitors connected to a laptop. The laptop has one HDMI and one VGA output. When one of the monitors is connected using VGA, it flickers or displays static noise. The flickering is fairly subtle and only visible on darker colors. But it is there and noticable and appears like horizontal lines. The problem only appears on the monitor connected to the laptop using the VGA cable. If I swap the monitors, the one connected using VGA is displaying the flicker but not the one connected using HDMI. The simple solution would ofcourse be to connect both monitors using HDMI, but since the laptop only has one VGA and one HDMI out that isn't possible. I've tried tweaking the monitor setting using the OSD menu, but it had little or no effect. Update: After several more trouble shooting hours, it seems the problem is not related to the monitor or VGA cable as the problem persists even if I swap the display with another brand and different cables. So it may be the graphics card? Intel HD Graphics 4000. The laptop is Acer Aspire E1-571.

• Disk IO causing high load on Xen/CentOS guest

  I'm having serious issues with a xen based server, this is on the guest partition. It's a paravirtualized CentOS 5.5.

• Forwarding emails to nonexisting users/aliases to external mail server

  - by Niclas Lindqvist

  I'm in the works of installing a postfix mailserver on a machine currently being used as web server. As of right now, I've got it working as far as that I can send and receive emails using telnet through port 25. However, as my customer is concerned with downtime, I'd like to setup all the accounts one by one over time, and making sure it works, rather than just cutting the cord to the old mail server and start creating new accounts on the new system. How can I add the domain customer.com to my mail server and just add something like [email protected] to the users and aliases-lists without the web server trying to send all emails with the @customer.com domain to the new mail server? I'm running ubuntu, using postfix and postfix-mysql on the new machine, the old mail server is on a hosted environment somewhere else, where I don't have any control.

• Updating AFP version on Windows Server 2003

  - by Niclas Lindqvist

  Hi, We have a couple of Macs, running Leopard and Snow Leopard in our otherwise pure Windows environment. We cannot get file names longer than 31 characters and some times the file permissions gets scrabbled (users can't delete their own folders or access files they usually access). This only occurs when connecting through AFP, We've tried with SMB but it's horribly slow when working with larger documents, so it's not an option. I somewhere read about AFP 3.0 being the answer. So my question is: Is there some way of updating my "AFP version" on Windows Server 2003, or does anyone have a different idea of what might help to resolve this situation?

• rails, mysql charsets & encoding: binary

  - by Benjamin Vetter

  Hi, i've a rails app that runs using utf-8. It uses a mysql database, all tables with mysql's default charset and collation (i.e. latin1). Therefore the latin1 tables contain utf-8 data. Sure, that's not nice, but i'm not really interested in it. Everything works fine, because the connection encoding is latin1 as well and therefore mysql does not convert between charsets. Only one problem: i need a utf-8 fulltext index for one table: mysql> show create table autocompletephrases; ... AUTO_INCREMENT=310095 DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci But: I don't want to convert between charsets in my rails app. Therefore I would like to know if i could just set config/database.yml production: adapter: mysql >>>> encoding: binary ... which just calls SET NAMES 'binary' when connecting to mySQL. It looks like it works for my case, because i guess it forces mysql to -not- convert between charsets (mySQL docs). Does anyone knows about problems about doing this? Any side-effects? Or do you have any other suggestions? But i'd like to avoid converting my whole database to utf-8. Many Thanks! Benjamin

• How do you efficiently implement a document similarity search system?

  - by Björn Lindqvist

  How do you implement a "similar items" system for items described by a set of tags? In my database, I have three tables, Article, ArticleTag and Tag. Each Article is related to a number of Tags via a many-to-many relationship. For each Article i want to find the five most similar articles to implement a "if you like this article you will like these too" system. I am familiar with Cosine similarity and using that algorithm works very well. But it is way to slow. For each article, I need to iterate over all articles, calculate the cosine similarity for the article pair and then select the five articles with the highest similarity rating. With 200k articles and 30k tags, it takes me half a minute to calculate the similar articles for a single article. So I need another algorithm that produces roughly as good results as cosine similarity but that can be run in realtime and which does not require me to iterate over the whole document corpus each time. Maybe someone can suggest an off-the-shelf solution for this? Most of the search engines I looked at does not enable document similarity searching.

• Efficiently finding the shortest path in large graphs

  - by Björn Lindqvist

  I'm looking to find a way to in real-time find the shortest path between nodes in a huge graph. It has hundreds of thousands of vertices and millions of edges. I know this question has been asked before and I guess the answer is to use a breadth-first search, but I'm more interested in to know what software you can use to implement it. For example, it would be totally perfect if it already exist a library (with python bindings!) for performing bfs in undirected graphs.

You can review it here: https://connect.microsoft.com/VisualStudio/feedback/details/560184/move-inotifycollectionchanged-from-system-windows-dll-to-system-dll Here’s the reason why I suggest that. Actually I wanted to take advantages of the new feature of Silverlight/Visual Studio 2010 for sharing assemblies (see http://blogs.msdn.com/clrteam/archive/2009/12/01/sharing-silverlight-assemblies-with-net-apps.aspx). Everything went fine until I try to share a custom collection (with custom business logic) implementing INotifyCollectionChanged. This modification has been made in the .NET Framework 4 (see https://connect.microsoft.com/VisualStudio/feedback/details/488607/move-inotifycollectionchanged-to-system-dll) so maybe it could be done in Silverlight too. If you think this is justifiable you can vote for it.

• [Windows 8] Update TextBox’s binding on TextChanged

  - by Benjamin Roux

  Since UpdateSourceTrigger is not available in WinRT we cannot update the text’s binding of a TextBox at will (or at least not easily) especially when using MVVM (I surely don’t want to write behind-code to do that in each of my apps !). Since this kind of demand is frequent (for example to disable of button if the TextBox is empty) I decided to create some attached properties to to simulate this missing behavior. namespace Indeed.Controls { public static class TextBoxEx { public static string GetRealTimeText(TextBox obj) { return (string)obj.GetValue(RealTimeTextProperty); } public static void SetRealTimeText(TextBox obj, string value) { obj.SetValue(RealTimeTextProperty, value); } public static readonly DependencyProperty RealTimeTextProperty = DependencyProperty.RegisterAttached("RealTimeText", typeof(string), typeof(TextBoxEx), null); public static bool GetIsAutoUpdate(TextBox obj) { return (bool)obj.GetValue(IsAutoUpdateProperty); } public static void SetIsAutoUpdate(TextBox obj, bool value) { obj.SetValue(IsAutoUpdateProperty, value); } public static readonly DependencyProperty IsAutoUpdateProperty = DependencyProperty.RegisterAttached("IsAutoUpdate", typeof(bool), typeof(TextBoxEx), new PropertyMetadata(false, OnIsAutoUpdateChanged)); private static void OnIsAutoUpdateChanged(DependencyObject sender, DependencyPropertyChangedEventArgs e) { var value = (bool)e.NewValue; var textbox = (TextBox)sender; if (value) { Observable.FromEventPattern<TextChangedEventHandler, TextChangedEventArgs>( o => textbox.TextChanged += o, o => textbox.TextChanged -= o) .Do(_ => textbox.SetValue(TextBoxEx.RealTimeTextProperty, textbox.Text)) .Subscribe(); } } } } .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } The code is composed of two attached properties. The first one “RealTimeText” reflects the text in real time (updated after each TextChanged event). The second one is only used to enable the functionality. To subscribe to the TextChanged event I used Reactive Extensions (Rx-Metro package in Nuget). If you’re not familiar with this framework just replace the code with a simple: textbox.TextChanged += textbox.SetValue(TextBoxEx.RealTimeTextProperty, textbox.Text); .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } To use these attached properties, it’s fairly simple <TextBox Text="{Binding Path=MyProperty, Mode=TwoWay}" ic:TextBoxEx.IsAutoUpdate="True" ic:TextBoxEx.RealTimeText="{Binding Path=MyProperty, Mode=TwoWay}" /> .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } Just make sure to create a binding (in TwoWay) for both Text and RealTimeText. Hope this helps !

• [WP7] How to decompile WP7 assemblies

  - by Benjamin Roux

  The other day I wanted to check the source code of the ScrollViewer of WP7. I started Reflector (profit while its still free) and I opened the System.Windows.dll assembly located at C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\Silverlight\v4.0\Profile\WindowsPhone. When Reflector did the job I was surprised to see that all the methods/properties were empty ! After some investigations, I found out that these assemblys are used by Visual Studio for the Intelisense (among others) and so, for develoment. The thing is I still couldn’t check the ScrollViewer’s source code. Finally after new investigations, I discovered a link on the XDA forum which provide the WP7 emulator dump. I downloaded it and decompiled the GAC_System.Windows_v2_0_5_0_cneutral_1.dll assembly located this time at /SYS/SILVERLIGHT. Et voila, the ScrollViewer’s source code is available. Hope this helps.

• How to use integrated Intel graphics instead of Nvidia graphics on MacBook Pro?

  - by Benjamin Geese

  I am running Ubuntu 12.04 64bit on MacBook Pro 15" 2010 (MacBookPro6,2) and I would like to use the integrated Intel graphics instead of the dedicated Nvidia graphics Ubuntu boots with on this machine. I am booting with UEFI, not REFIT or similar. I managed to switch to UEFI with the help of this page. This wiki page also contains tips on switching to Intel graphics which include some (for me) cryptic boot commands to grub. However if I follow the guide, my display stays just black. Currently, I am only looking for solution to use Intel graphics for Ubuntu to save power and keep my MacBook cool. Dynamic switching or stuff like that is not required.
