  • Which framework would you recommend to use to add "social networking" components to a website?

    - by blueberryfields
    Given which already enables users to create and publish content, is there a service or tool which can add the standard social networking suite of components? Specifically, I'm looking quickly add functionality which allows users to friend each other, vote on/like/rank content on the site, send each other links to parts they find interesting, chat and send offline message each other. There's no specific limitation on the technology used for these components - as long as its been proven to work, and scales without issue. I'd slightly prefer a solution which is offered as a service rather than one that I have to install. Edit Some additional commenter requested clarifications - there are no restrictions that the site imposes on user identification or authentication. Feel free to assume that portion of the work is not relevant to the answers.

  • Microsoft Generation 4 Datacenter using ITPACs

    - by Eric Nelson
    Microsoft is continuing to make significant investments in Datacenter technology and is focused on solving issues such as long lead times, significant up-front costs and over capacity. Enter the world of modular Datacenters and ITPACs – IT Pre-Assembled Components. In simple terms – air handling and IT units which are pre-assembled (looking somewhat like a container) and then installed on concrete bases. Each unit can hold  between 400 and 2500 servers (which means many more virtual machines depending on your density) Kevin Timmons’, manager of the datacenter operations team, just posted a great post digging into the detail One Small Step for Microsoft’s Cloud, Another Big Step for Sustainability which includes a short video on how we build one of these ITPACs.

  • RDF and OWL: Have these delivered the promises of the Semantic Web?

    - by Dark Templar
    These days I've been learning a lot about how different scientific fields are trying to move their data over to the Semantic Web in order to "free up data from being stored in isolated silos". I read a lot about how these fields are saying how their efforts are implementing the "visions" of the Semantic Web. As a learner (and from purely a learning perspective) I was curious to know why, if semantic technology is deemed to be so powerful, the efforts have been around for years but myself and a lot of people I know have never even heard of it until very recently? Also, I don't come across any scholarly articles deeming "oh, our inferencing engine was able to make such and such discovery, which is helping us pave our way to solving...." etc. It seems that there are genuine efforts across different institutions, fields, and disciplines to shift all their data to a "semantic" format, but what happens after all that's been done? All the ontologies have been created/unified, and then what?

  • Find the best OpenWorld sessions for learning about UX highlights

    - by mvaughan
    By Kathy Miedema, Oracle Applications User Experience  Have you clicked through the Oracle OpenWorld 2012 catalog? It’s amazingly dense, as usual. But one thing we noticed this year is that nearly half of the sessions mention some component of user experience, which is a sea change in our world. It means that more people understand, appreciate, and desire an effective user experience, and it also means that Oracle’s investment in its next-generation applications user experience, such as Oracle Fusion Applications, is increasingly apparent and interesting to its customers.

  • Big Data – Various Learning Resources – How to Start with Big Data? – Day 20 of 21

    - by Pinal Dave
    In yesterday’s blog post we learned how to become a Data Scientist for Big Data. In this article we will go over various learning resources related to Big Data. In this series we have covered many of the most essential details about Big Data. At the beginning of this series, I have encouraged readers to send me questions. One of the most popular questions is - “I want to learn more about Big Data. Where can I learn it?” This is indeed a great question as there are plenty of resources out to learn about Big Data and it is indeed difficult to select on one resource to learn Big Data. Hence I decided to write here a few of the very important resources which are related to Big Data. Learn from Pluralsight Pluralsight is a global leader in high-quality online training for hardcore developers.  It has fantastic Big Data Courses and I started to learn about Big Data with the help of Pluralsight. Here are few of the courses which are directly related to Big Data. Big Data: The Big Picture Big Data Analytics with Tableau NoSQL: The Big Picture Understanding NoSQL Data Analysis Fundamentals with Tableau I encourage all of you start with this video course as they are fantastic fundamentals to learn Big Data. Learn from Apache Resources at Apache are single point the most authentic learning resources. If you want to learn fundamentals and go deep about every aspect of the Big Data, I believe you must understand various concepts in Apache’s library. I am pretty impressed with the documentation and I am personally referencing it every single day when I work with Big Data. I strongly encourage all of you to bookmark following all the links for authentic big data learning. Haddop - The Apache Hadoop® project develops open-source software for reliable, scalable, distributed computing. Ambari: A web-based tool for provisioning, managing, and monitoring Apache Hadoop clusters which include support for Hadoop HDFS, Hadoop MapReduce, Hive, HCatalog, HBase, ZooKeeper, Oozie, Pig and Sqoop. Ambari also provides a dashboard for viewing cluster health such as heat maps and ability to view MapReduce, Pig and Hive applications visually along with features to diagnose their performance characteristics in a user-friendly manner. Avro: A data serialization system. Cassandra: A scalable multi-master database with no single points of failure. Chukwa: A data collection system for managing large distributed systems. HBase: A scalable, distributed database that supports structured data storage for large tables. Hive: A data warehouse infrastructure that provides data summarization and ad hoc querying. Mahout: A Scalable machine learning and data mining library. Pig: A high-level data-flow language and execution framework for parallel computation. ZooKeeper: A high-performance coordination service for distributed applications. Learn from Vendors One of the biggest issues with about learning Big Data is setting up the environment. Every Big Data vendor has different environment request and there are lots of things require to set up Big Data framework. Many of the users do not start with Big Data as they are afraid about the resources required to set up framework as well as a time commitment. Here Hortonworks have created fantastic learning environment. They have created Sandbox with everything one person needs to learn Big Data and also have provided excellent tutoring along with it. Sandbox comes with a dozen hands-on tutorial that will guide you through the basics of Hadoop as well it contains the Hortonworks Data Platform. I think Hortonworks did a fantastic job building this Sandbox and Tutorial. Though there are plenty of different Big Data Vendors I have decided to list only Hortonworks due to their unique setup. Please leave a comment if there are any other such platform to learn Big Data. I will include them over here as well. Learn from Books There are indeed few good books out there which one can refer to learn Big Data. Here are few good books which I have read. I will update the list as I will learn more. Ethics of Big Data Balancing Risk and Innovation Big Data for Dummies Head First Data Analysis: A Learner’s Guide to Big Numbers, Statistics, and Good Decisions If you search on Amazon there are millions of the books but I think above three books are a great set of books and it will give you great ideas about Big Data. Once you go through above books, you will have a clear idea about what is the next step you should follow in this series. You will be capable enough to make the right decision for yourself. Tomorrow In tomorrow’s blog post we will wrap up this series of Big Data.

  • SUPINFO International University in Mauritius

    Since a while I'm considering to pick up my activities as a student and I'd like to get a degree in Computer Science. Personal motivation I mean after all this years as a professional software (and database) developer I have the personal urge to complete this part of my education. Having various certifications by Microsoft and being awarded as an Microsoft Most Valuable Professional (MVP) twice looks pretty awesome on a resume but having a "proper" degree would just complete my package. During the last couple of years I already got in touch with C-SAC (local business school with degree courses), the University of Mauritius and BCS, the Chartered Institute for IT to check the options to enroll as an experienced software developer. Quite frankly, it was kind of alienating to receive that feedback: Start from scratch! No seriously? Spending x amount of years to sit for courses that might be outdated and form part of your daily routine? Probably being in an awkward situation in which your professional expertise might exceed the lecturers knowledge? I don't know... but if that's path to walk... Well, then I might have to go for it. SUPINFO International University Some weeks ago I was contacted by the General Manager, Education Recruitment and Development of Medine Education Village, Yamal Matabudul, to have a chat on how the local IT scene, namely the Mauritius Software Craftsmanship Community (MSCC), could assist in their plans to promote their upcoming campus. Medine went into partnership with the French-based SUPINFO International University and Mauritius will be the 36th location world-wide for SUPINFO. Actually, the concept of SUPINFO is very likely to the common understanding of an apprenticeship in Germany. Not only does a student enroll into the programme but will also be placed into various internships as part of the curriculum. It's a big advantage in my opinion as the person stays in touch with the daily procedures and workflows in the real world of IT. Statements like "We just received a 'crash course' of information and learned new technology which is equivalent to 1.5 months of lectures at the university" wouldn't form part of the experience of such an education. Open Day at the Medine Education Village Last Saturday, Medine organised their Open Day and it was the official inauguration of the SUPINFO campus in Mauritius. It's now listed on their website, too - but be warned, the site is mainly in French language although the courses are all done in English. Not only was it a big opportunity to "hang out" on the campus of Medine but it was great to see the first professional partners for their internship programme, too. Oh, just for the records, IOS Indian Ocean Software Ltd. will also be among the future employers for SUPINFO students. More about that in an upcoming blog entry. Open Day at Medine Education Village - SUPINFO International University in Mauritius Mr Alick Mouriesse, President of SUPINFO, arrived the previous day and he gave all attendees a great overview of the roots of SUPINFO, the general development of the educational syllabus and their high emphasis on their partnerships with local IT companies in order to assist their students to get future jobs but also feel the heartbeat of technology live. Something which is completely missing in classic institutions of tertiary education in Computer Science. And since I was on tour with my children, as usual during weekends, he also talked about the outlook of having a SUPINFO campus in Mauritius. Apart from the close connection to IT companies and providing internships to students, SUPINFO clearly works on an international level. Meaning students of SUPINFO can move around the globe and can continue their studies seamlessly. For example, you might enroll for your first year in France, then continue to do 2nd and 3rd year in Canada or any other country with a SUPINFO campus to earn your bachelor degree, and then live and study in Mauritius for the next 2 years to achieve a Master degree. Having a chat with Dale Smith, Expand Technologies, after his interesting session on Technological Entrepreneurship - TechPreneur More questions by other craftsmen of the Mauritius Software Craftsmanship Community And of course, this concept works in any direction, giving Mauritian students a huge (!) opportunity to live, study and work abroad. And thanks to this, Medine already announced that there will be new facilities near Cascavelle to provide dormitories and other facilities to international students coming to our island. Awesome! Okay, but why SUPINFO? Well, coming back to my original statement - I'd like to get a degree in Computer Science - SUPINFO has a process called Validation of Acquired Experience (VAE) which is tailor-made for employees in the field of IT, and allows you to enroll in their course programme. I already got in touch with their online support chat but was only redirected to some FAQs on their website, unfortunately. So, during the Open Day I seized the opportunity to have an one-on-one conversation with Alick Mouriesse, and he clearly encouraged me to gather my certifications and working experience. SUPINFO does an individual evaluation prior to their assignment regarding course level, and hopefully my chances of getting some modules ahead of studies are looking better than compared to the other institutes. Don't get me wrong, I don't want to go down the easy route but why should someone sit for "Database 101" or "Principles of OOP" when applying and preaching database normalisation and practicing Clean Code Developer are like flesh and blood? Anyway, I'll be off to get my transcripts of certificates together with my course assignments from the old days at the university. Yes, I studied Applied Chemistry for a couple of years before intersecting into IT and software development particularly... ;-)

  • How to restore your production database without needing additional storage

    - by David Atkinson
    Production databases can get very large. This in itself is to be expected, but when a copy of the database is needed the database must be restored, requiring additional and costly storage.  For example, if you want to give each developer a full copy of your production server, you'll need n times the storage cost for your n-developer team. The same is true for any test databases that are created during the course of your project lifecycle. If you've read my previous blog posts, you'll be aware that I've been focusing on the database continuous integration theme. In my CI setup I create a "production"-equivalent database directly from its source control representation, and use this to test my upgrade scripts. Despite this being a perfectly valid and practical thing to do as part of a CI setup, it's not the exact equivalent to running the upgrade script on a copy of the actual production database. So why shouldn't I instead simply restore the most recent production backup as part of my CI process? There are two reasons why this would be impractical. 1. My CI environment isn't an exact copy of my production environment. Indeed, this would be the case in a perfect world, and it is strongly recommended as a good practice if you follow Jez Humble and David Farley's "Continuous Delivery" teachings, but in practical terms this might not always be possible, especially where storage is concerned. It may just not be possible to restore a huge production database on the environment you've been allotted. 2. It's not just about the storage requirements, it's also the time it takes to do the restore. The whole point of continuous integration is that you are alerted as early as possible whether the build (yes, the database upgrade script counts!) is broken. If I have to run an hour-long restore each time I commit a change to source control I'm just not going to get the feedback quickly enough to react. So what's the solution? Red Gate has a technology, SQL Virtual Restore, that is able to restore a database without using up additional storage. Although this sounds too good to be true, the explanation is quite simple (although I'm sure the technical implementation details under the hood are quite complex!) Instead of restoring the backup in the conventional sense, SQL Virtual Restore will effectively mount the backup using its HyperBac technology. It creates a data and log file, .vmdf, and .vldf, that becomes the delta between the .bak file and the virtual database. This means that both read and write operations are permitted on a virtual database as from SQL Server's point of view it is no different from a conventional database. Instead of doubling the storage requirements upon a restore, there is no 'duplicate' storage requirements, other than the trivially small virtual log and data files (see illustration below). The benefit is magnified the more databases you mount to the same backup file. This technique could be used to provide a large development team a full development instance of a large production database. It is also incredibly easy to set up. Once SQL Virtual Restore is installed, you simply run a conventional RESTORE command to create the virtual database. This is what I have running as part of a nightly "release test" process triggered by my CI tool. RESTORE DATABASE WidgetProduction_virtual FROM DISK=N'C:\WidgetWF\ProdBackup\WidgetProduction.bak' WITH MOVE N'WidgetProduction' TO N'C:\WidgetWF\ProdBackup\WidgetProduction_WidgetProduction_Virtual.vmdf', MOVE N'WidgetProduction_log' TO N'C:\WidgetWF\ProdBackup\WidgetProduction_log_WidgetProduction_Virtual.vldf', NORECOVERY, STATS=1, REPLACE GO RESTORE DATABASE mydatabase WITH RECOVERY   Note the only change from what you would do normally is the naming of the .vmdf and .vldf files. SQL Virtual Restore intercepts this by monitoring the extension and applies its magic, ensuring the 'virtual' restore happens rather than the conventional storage-heavy restore. My automated release test then applies the upgrade scripts to the virtual production database and runs some validation tests, giving me confidence that were I to run this on production for real, all would go smoothly. For illustration, here is my 8Gb production database: And its corresponding backup file: Here are the .vldf and .vmdf files, which represent the only additional used storage for the new database following the virtual restore.   The beauty of this product is its simplicity. Once it is installed, the interaction with the backup and virtual database is exactly the same as before, as the clever stuff is being done at a lower level. SQL Virtual Restore can be downloaded as a fully functional 14-day trial. Technorati Tags: SQL Server
