  • eLearning event on HTML5 for Mobile with jQuery Mobile

    - by Wallym
    I'll be doing an eLearning event on HTML5 for Mobile with jQuery Mobile. There will also be a few items sprinkled in on ASP.NET Razor. Mobile development is a hot item. Customers are buying iPhones, iPads, Android devices, and many other mobile computing devices at an ever increasing record pace. Devices based on iOS and Android are nearly 80 percent of the marketplace. RIM continues to be dominant in the business area across the world. Nokia's growth with Windows Phone will grow on a worldwide basis. At the same time, clearly web development is a tremendous driver of applications, both on the public Internet and on private networks. How can developers target these various mobile platforms with web technologies? Developers can write web applications that take advantage of each mobile platform, but that is a lot of work. Into this space, the jQuery Mobile framework was developed. This eLearning series will provide an overview of mobile web development with jQuery Mobile, a detailed look at what the jQuery Mobile framework provides for us, how we can customize jQuery Mobile, and how we can use jQuery Mobile inside of ASP.NET.Link: http://elearning.left-brain.com/event/mobile-web-development

  • Working with Temporal Data in SQL Server

    - by Dejan Sarka
    My third Pluralsight course, Working with Temporal Data in SQL Server, is published. I am really proud on the second part of the course, where I discuss optimization of temporal queries. This was a nearly impossible task for decades. First solutions appeared only lately. I present all together six solutions (and one more that is not a solution), and I invented four of them. http://pluralsight.com/training/Courses/TableOfContents/working-with-temporal-data-sql-server

  • Visual Studio Talk Show #118 is now online - Command-Query Responsibility Separation (French)

    - by guybarrette
    http://www.visualstudiotalkshow.com Erik Renaud: La séparation des responsabilités entre les commandes et les requêtes Nous discutons avec Erik Renaud de la séparation des responsabilités entre les commandes et les requêtes (Command-Query Responsibility Separation - CQRS). La plupart des applications lisent les données beaucoup plus fréquemment qu'ils font des écritures. Sur la base de cette déclaration, une bonne idée consiste à séparer le code qui est responsable de l’écriture des données du code qui est responsable des requêtes (lecture). Erik Renaud est un coach .NET et co-fondateur de nVentive, une société conseil qui aide les équipes de développement logiciel au moyen de « coaching » et de « guidance ». Ses mandats courants se concentrent dans les grandes institutions financières en créant de nouvelles équipes qui supportent directement leurs activités primaires. Erik cumule plus de 10 ans d’expérience en développement logiciel, en faisant du coaching pour des équipes pour des besoins en architecture, modélisation et analyse. Pour la seconde année, il a reçu de Microsoft la reconnaissance MVP. Il est un ScrumMaster certifié, ce qui l’aide à guider les équipes vers le succès, et offre souvent des formations pour les technologies orientées objet.

  • Advice for good web server development setup.

    - by John Berryman
    A month or so ago I created my first LAMP stack and implemented a simple web site that exercised each letter in that acronym. However my development setup was much less than ideal. I don't really have a local test server, but instead I was writing all of my CGI scripts in vim while ssh'ed into the remote machine as root. Now I intend to start more serious development. Question: What is a good setup so that development goes as easily as possible? I would like to understand what is available to me along the lines of an IDE, subversion (or alternatives), uploading and downloading content, and just best practices. I'm pretty new at all of this. Also, feel free to point me at good websites. There's plenty of websites, but only people who are already heavily developing web content are able to quickly determine if they are good websites.

  • How do I make complex SQL queries easier to write?

    - by DragonLord
    I'm finding it very difficult to write complex SQL queries involving joins across many (at least 3-4) tables and involving several nested conditions. The queries I'm being asked to write are easily described by a few sentences, but can require a deceptive amount of code to complete. I'm finding myself often using temporary views to write these queries, which seem like a bit of a crutch. What tips can you provide that I can use to make these complex queries easier? More specifically, how do I break these queries down into the steps I need to use to actually write the SQL code? Note that I'm the SQL I'm being asked to write is part of homework assignments for a database course, so I don't want software that will do the work for me. I want to actually understand the code I'm writing. More technical details: The database is hosted on a PostgreSQL server running on the local machine. The database is very small: there are no more than seven tables and the largest table has less than about 50 rows. The SQL queries are being passed unchanged to the server, via LibreOffice Base.

    First and foremost : Huge thanks, and huge apologies, to everyone who attended my sessions at these events. I promised to post materials last week, and there is no good excuse for tardiness. My dog did not eat my computer. I don't have a dog. And if I did, she would far prefer a nice rib eye to a hard chunk of plastic. Now, on to the purpose of this post... Last week I was lucky enough to have a first visit to each of two amazing cities, Stockholm and Amsterdam. Both cities, as mentioned previously...(read more)

  • mp3 file streaming/download - apache server memory issue

    - by Manolis
    I have a website, in which users can upload mp3 files (uploadify), stream them using an html5 player (jplayer) and download them using a php script (www.zubrag.com/scripts/). When a user uploads a song, the path to the audio file is saved in the database and i'm using that data in order to play and show a download link for the song. The problem that i'm experiencing is that, according to my host, this method is using a lot of memory on the server, which is dedicated. Link to script: http://pastebin.com/Vus8SRa7 How should I handle the script properly? And what would be the best way to track down the problem? Any ideas on cleaning up the code? Any help much appreciated.

  • Correct DB details produce “Database server was not found” (Prestashop Installation)

    - by Steve
    At stage 3 of the Prestashop Installation, I enter the DB details which I know to be correct, and I receive the error: Database server was not found. Please verify the login, password, and database server name fields. The server is localhost, and I have verified the database name and username. Why can Prestashop not find the server? This occurs when choosing InnoDB and MyIsam. If I change the server from localhost to the public hostname I receive the same error.

  • embedding LEFT OUTER JOIN within INNER JOIN

    - by user3424954
    I am having some problems with one of the question's answered in the book "SQL FOR MERE MORTALS". Here is the problem statement Here is the Database Structure Here is the answer which I am unable to comprehend Here is an answer which looks perfect to me Now the problem with the first answer I am having is: We first use LEFT OUTER JOIN for recipe class and recipes. So it selects all recipe class rows but only matching recipes. Perfecty fine as the question is demanding. Lets call this result set R. Now in the next step when we use INNER JOIN to join RecipieIngridients, it should filter out the rows from R in which Recipie ID doesn't match with the Recipe Id in Recipie Ingredients and hence filtering out the related Recipe class and recipe description also(Since it filters out the entire row of R). So this contradicts with the problem which demands all recipieID and RecipieDescription to be displayed from Recipe_Classes Table in this very step only. How can it be correct. Or Am i Missing some concept.

  • Is it possible to make a MS-SQL Scalar function do this?

    - by Hokken
    I have a 3rd party application that can call a MS-SQL scalar function to return some summary information from a table. I was able to return the summary values with a table-valued function, but the application won't utilize table-valued functions, so I'm kind of stuck. Here's a sample from the table: trackingNumber, projTaskAward, expenditureType, amount 1122, 12345-67-89, Supplies, 100 1122, 12345-67-89, Supplies, 150 1122, 12345-67-89, Supplies, 250 1122, 12345-67-89, Misc, 50 1122, 12345-67-89, Misc, 100 1122, 98765-43-21, General, 200 1122, 98765-43-21, Conference, 500 1122, 98765-43-21, Misc, 300 1122, 98765-43-21, Misc, 100 1122, 98765-43-21, Misc, 100 I want to summarize the amounts by projTaskAward & expenditureType, based on the trackingNumber. Here is the output I'm looking for: Proj/Task/Award: 12345-67-89 Expenditure Type: Supplies Total: 500 Proj/Task/Award: 12345-67-89 Expenditure Type: Misc Total: 150 Proj/Task/Award: 98765-43-21 Expenditure Type: General Total: 200 Proj/Task/Award: 98765-43-21 Expenditure Type: Conference Total: 500 Proj/Task/Award: 98765-43-21 Expenditure Type: Misc Total: 500 I'd appreciate any help anyone can give in steering me in the right direction.
