  • Generate Multiple Choice Questions [closed]

    - by Daniel
    I'm working on a quiz application that will have a number of multiple choice questions. I'm waiting on the content from the client, but I'm hoping to start testing with some placeholder data for the time being. In order for the tests to be worthwhile, I probably need at least 100 multiple choice questions. I wanted to see if anyone knows of a resource or tool that can generate questions/multiple choice answers or propose another creative way to fill my quiz application with placeholder content. Ultimately the data will be in a MySQL database, but I don't really care what format the sample data is in (Excel, Word, JSON, etc.).

  • node-xmpp-bosh error on Ubuntu 11.10

    - by megueloby
    I am newbie in Linux word. I want to implement a bosh server. Because it is hard on Windows platform I decided to deploy it on a Ubuntu virtual machine via vmware. I made installation without problems. I followed the processes on this page. Now I want to test my bosh server with the command sudo bosh or sudo /etc/init.d/bosh start, after typing those I get on the terminal Starting bosh server after, nothing. I looked on the bosh.err file and I see exec: 2: /usr/local/lib/bosh/run-server.js: Permission denied I don? t know why this error with sudo. When I try ls -l /usr/local/lib/bosh/run-server.js it show -rw-r--r-- 1 root root 4889 2012-04-01 18:50 /usr/local/lib/bosh/run-server.js How can I make bosh start?

  • Five development tools I can't live without

    - by bconlon
    When applying to join Geeks with Blogs I had to specify the development tools I use every day. That got me thinking, it's taken a long time to whittle my tools of choice down to the selection I use, so it might be worth sharing. Before I begin, I appreciate we all have our preferred development tools, but these are the ones that work for me. Microsoft Visual Studio Microsoft Visual Studio has been my development tool of choice for more years than I care to remember. I first used this when it was Visual C++ 1.5 (hats off to those who started on 1.0) and by 2.2 it had everything I needed from a C++ IDE. Versions 4 and 5 followed and if I had to guess I would expect more Windows applications are written in VC++ 6 and VB6 than any other language. Then came the not so great versions Visual Studio .Net 2002 (7.0) and 2003 (7.1). If I'm honest I was still using v6. 2005 was better and 2008 was simply brilliant. Everything worked, the compiler was super fast and I was happy again...then came 2010...oh dear. 2010 is a big step backwards for me. It's not encouraging for my upcoming WPF exploits that 2010 is fronted in WPF technology, with the forever growing Find/Replace dialog, the issues with C++ intellisense, and the buggy debugger. That said it is still my tool of choice but I hope they sort the issue in SP1. I've tried other IDEs like Visual Age and Eclipse, but for me Visual Studio is the best. A really great tool. Liquid XML Studio XML development is a tricky business. The W3C standards are often difficult to get to the bottom of so it's great to have a graphical tool to help. I first used Liquid Technologies 5 or 6 years back when I needed to process XML data in C++. Their excellent XML Data Binding tool has an easy to use Wizard UI (as compared to Castor or JAXB command line tools) and allows you to generate code from an XML Schema. So instead of having to deal with untyped nodes like with a DOM parser, instead you get an Object Model providing a custom API in C++, C#, VB etc. More recently they developed a graphical XML IDE with XML Editor, XSLT, XQuery debugger and other XML tools. So now I can develop an XML Schema graphically, click a button to generate a Sample XML document, and click another button to run the Wizard to generate code including a Sample Application that will then load my Sample XML document into the generated object model. This is a very cool toolset. Note: XML Data Binding is nothing to do with WPF Data Binding, but I hope to cover both in more detail another time. .Net Reflector Note: I've just noticed that starting form the end of February 2011 this will no longer be a free tool !! .Net Reflector turns .Net byte code back into C# source code. But how can it work this magic? Well the clue is in the name, it uses reflection to inspect a compiled .Net assembly. The assembly is compiled to byte code, it doesn't get compiled to native machine code until its needed using a just-in-time (JIT) compiler. The byte code still has all of the information needed to see classes, variables. methods and properties, so reflector gathers this information and puts it in a handy tree. I have used .Net Reflector for years in order to understand what the .Net Framework is doing as it sometimes has undocumented, quirky features. This really has been invaluable in certain instances and I cannot praise enough kudos on the original developer Lutz Roeder. Smart Assembly In order to stop nosy geeks looking at our code using a tool like .Net Reflector, we need to obfuscate (mess up) the byte code. Smart Assembly is a tool that does this. Again I have used this for a long time. It is very quick and easy to use. Another excellent tool. Coincidentally, .Net Reflector and Smart Assembly are now both owned by Red Gate. Again kudos goes to the original developer Jean-Sebastien Lange. TortoiseSVN SVN (Apache Subversion) is a Source Control System developed as an open source project. TortoiseSVN is a graphical UI wrapper over SVN that hooks into Windows Explorer to enable files to be Updated, Committed, Merged etc. from the right click menu. This is an essential tool for keeping my hard work safe! Many years ago I used Microsoft Source Safe and I disliked CVS type systems. But TortoiseSVN is simply the best source control tool I have ever used. --- So there you have it, my top 5 development tools that I use (nearly) every day and have helped to make my working life a little easier. I'm sure there are other great tools that I wish I used but have never heard of, but if you have not used any of the above, I would suggest you check them out as they are all very, very cool products. #

  • Is there any text editor for windows which can save files with code highlight for viewing

    - by user1713836
    I want some software for Windows where I can save code snippets and other daily usable commands in one file. Everyday I find some small code snippets which I want to save in a single file. Just like we have code snippet savers online, I want something offline on Windows, basically with all the features Microsoft Word has, but with code highlight. It should be lightweight like Notepad++. I mean if I select the code and then press some button, it should change the color according to the language. Currently I use Notepad++, but in it, I can't select small code snippets on one page. It either highlights the entire file or nothing.

  • Programming Geek's CV Design

    - by benhowdle89
    What is the best practice or advice for a programmer's CV? If I were a graphic designer or more of a web designer as opposed to a programmer, then I'd imagine a CV would have a bit more flourish to it. Yet as a programmer, aren't we judged on not only efficiency and results but also creativity, imagination and initiative? Should this be reflected in a CV? Or is it all about the information, no wishy washy designs in sight? Has anyone experimented with an original alternative to a PDF CV with a template from MS Word or Mac Pages?

  • Is there a global "low resolution" filter for OpenGL?

    - by Ian Henry
    I'm trying to learn a little about OpenGL, so I'm making a simple 2D game (with OpenTK), and so far it's coming along well. I thought it would be fun to give it that, for lack of a better word, retropixelated look of games from the early nineties. I figured it would be an easy thing to do -- simply draw everything at half its normal size and scale up with no anti-aliasing. But I can't find any resources on how to do this. I can set the min/mag filters of my textures to nearest and that works fine for my sprites, but I'm using lots of primitives and I'd like the effect to apply to them as well. The one idea I had was to draw everything at half size, then somehow copy the render buffer to a texture, then render that texture full-size, but I don't know how to do that, and it seems like there must be a better way. Can anyone help me out?

  • GNU GRUB version 1.99-21ubuntu3, DOES NOT WORK!

    - by Arthur
    I'm new to Ubuntu, I installed it but when I try to start it, tells me that I need to run commands from bash-like and they can be shown by tab, when I press tab shows me the commands but then I type them and nothing happens, I have to reset my computer and the same thing goes on. This is what it says: GNU GRUB version 1.99-21ubuntu3 Minimal bash-like line editing is supported. For the first word, TAB lists possible command completions. Anywhere else TAB lists possible device or file completions. And nothing happens from there, can you tell what I need to do now? THANKS AGAIN!

  • Are there any formalized/mathematical theories of software testing?

    - by Erik Allik
    Googling "software testing theory" only seems to give theories in the soft sense of the word; I have not been able to find anything that would classify as a theory in the mathematical, information theoretical or some other scientific field's sense. What I'm looking for is something that formalizes what testing is, the notions used, what a test case is, the feasibility of testing something, the practicality of testing something, the extent to which something should be tested, formal definition/explanation of code coverage, etc. UPDATE: Also, I'm not sure, intuitively, about the connection between formal verification and what I asked, but there's clearly some sort of connection.

  • Ars Technica .ars URL suffix -- Vanity or SEO Benefit?

    - by yc01
    The Technology website Ars Technica has adjusted their URL rewrite rules to end with a .ars. Traditionally, sites have taken advantage of this URL rewriting capability to completely eliminate file suffixes like .html, .php, .aspx etc, under the theory that this made for better SEO (since the content of the URL was more relevant to the content) Ars Technicas, though, look like this: http://arstechnica.com/science/news/2011/03/flow-from-the-poles-drive-sunspot-levels.ars So, is Ars Technica adding the .ars file suffix purely a vanity play? Or is it an SEO trick to improve the site's SEO by cleverly inserting their site name into every URL slug? And, if this is indeed an effective SEO trick, should other sites follow suit?

  • Oracle RightNow CX for Good Customer Experiences

    - by Andreea Vaduva
    Oracle RightNow CX is all about the customer experience, it’s about understanding what drives a good interaction and it’s about delivering a solution which works for our customers and by extension, their customers. One of the early guiding principles of Oracle RightNow was an 8-point strategy to providing good customer experiences. Establish a knowledge foundation Empowering the customer Empower employees Offer multi-channel choice Listen to the customer Design seamless experiences Engage proactively Measure and improve continuously The application suite provides all of the tools necessary to deliver a rewarding, repeatable and measurable relationship between business and customer. The Knowledge Authoring tool provides gap analysis, WYSIWIG editing (and includes HTML rich content for non-developers), multi-level categorisation, permission based publishing and Web self-service publishing. Oracle RightNow Customer Portal, is a complete web application framework that enables businesses to control their own end-user page branding experience, which in turn will allow customers to self-serve. The Contact Centre Experience Designer builds a combination of workspaces, agent scripting and guided assistances into a Desktop Workflow. These present an agent with the tools they need, at the time they need them, providing even the newest and least experienced advisors with consistently accurate and efficient information, whilst guiding them through the complexities of internal business processes. Oracle RightNow provides access points for customers to feedback about specific knowledge articles or about the support site in general. The system will generate ‘incidents’ based on the scoring of the comments submitted. This makes it easy to view and respond to customer feedback. It is vital, more now than ever, not to under-estimate the power of the social web – Facebook, Twitter, YouTube – they have the ability to cause untold amounts of damage to businesses with a single post – witness musician Dave Carroll and his protest song on YouTube, posted in response to poor customer services from an American airline. The first day saw 150,000 views and is currently at 12,011,375. The Times reported that within 4 days of the post, the airline’s stock price fell by 10 percent, which represented a cost to shareholders of $180 million dollars. It is a universally acknowledged fact, that when customers are unhappy, they will not come back, and, generally speaking, it only takes one bad experience to lose a customer. The idea that customer loyalty can be regained by using social media channels was the subject of a 2011 Survey commissioned by RightNow and conducted by Harris Interactive. The survey discovered that 68% of customers who posted a negative review about a holiday on a social networking site received a response from the business. It further found that 33% subsequently posted a positive review and 34% removed the original negative review. Cloud Monitor provides the perfect mechanism for seeing what is being said about a business on public Facebook pages, Twitter or YouTube posts; it allows agents to respond proactively – either by creating an Oracle RightNow incident or by using the same channel as the original post. This leaves step 8 – Measuring and Improving: How does a business know whether it’s doing the right thing? How does it know if its customers are happy? How does it know if its staff are being productive? How does it know if its staff are being effective? Cue Oracle RightNow Analytics – fully integrated across the entire platform – Service, Marketing and Sales – there are in excess of 800 standard reports. If this were not enough, a large proportion of the database has been made available via the administration console, allowing users without any prior database experience to write their own reports, format them and schedule them for e-mail delivery to a distribution list. It handles the complexities of table joins, and allows for the manipulation of data with ease. Oracle RightNow believes strongly in the customer owning their solution, and to provide the best foundation for success, Oracle University can give you the RightNow knowledge and skills you need. This is a selection of the courses offered: RightNow Customer Service Administration Rel 12.02 (3 days) Available as In Class and Live Virtual Class (Release 11.11 is available as In Class, Live Virtual Class and Training On Demand) This course familiarises users with the tasks and concepts needed to configure and maintain their system.

  • On a queue, which end is the "head"?

    - by Aidan Cully
    I had always thought that the "head" of a queue as the next element to be read, and never really questioned that usage. So a linked-list library I wrote, which is used for maintaining queues, codified that terminology: we have a list1_head macro that retrieves the first element; when using this library in a queue, this will be the first element to be removed. But a new developer on the team was used to having queues implemented the other way around. He described a queue as behaving like a dog: you insert at the head, and remove at the tail. This is a clever enough description that I feel like his usage must be more widespread, and I don't have a similarly evocative description of my preferred usage. So, I guess, there are two related questions: 1, what does the "head" of a queue mean to you? and 2, why do we use the word "head" to describe that concept?

  • How to Search File Contents in Windows Server 2008 R2

    - by ybbest
    By default, windows search only search by File name. To configure windows search to search by contents you need configure the following: You need to make sure Windows Search Services feature is activated.(Check this article for details) Then, configure Windows Search by Open file explorer: Press Alt button –> go to tools –> Folder options –> search tab –> Here select, “Always search file names and content(this might take several minutes)” Press okay. Now your searches will work for file content like the good old days of XP. Another way to search the contents in file without Search configuration is to Type “contents:” in the Windows Explorer search box followed by the word, searches text files. This is a search filter which seems to be undocumented?

  • Why is there a "new" in Go?

    - by dystroy
    I'm still puzzled as why we have new in Go. When you want to instantiate a struct, you do t := Thing{} and, obviously, you can get a pointer to a new instance by doing t := &Thing{} But there's also this possibility : t := new(Thing) This last one seems a little alien to me. &Thing{} is as clear and concise as new(Thing) and it uses only constructs you often use elsewhere. It's also more extensible as you might change it to &Thing{3} or &Thing{Feets:7}. In my opinion, having a supplementary keyword is costly, it makes the language more complex and adds to what you must know. And it might mask to newcomers what's behind instantiating a struct. It also makes one more reserved word. So what's the reasoning behind new ? Is it something useful ? Should we use it ?

  • Gamification at OOW

    - by erikanollwebb
    Last week was Oracle OpenWorld, and for those of you not in tech or downtown San Francisco, that might not mean a whole lot.  However, if you are familiar with it, Oracle OpenWorld is our premier customer event.  This year, more than 50,000 people attended.  It's not a good week to visit San Francisco on vacation because Oracle customers take over all the hotels in town!  It was crazy, but a lot of fun and it's a great opportunity for the Apps UX group to do customer research with a range of customers.  This year, more than 100+ customers and partners took the time to team up with our UX experts and provide feedback on new designs and ideas. Over three days,  UX teams conducted 8  one-on-one user feedback sessions, 4 focus groups and 7 surveys. In addition, we conducted a voice capture activity and were able to collect close to 70 speech samples at the lab and DEMOgrounds. This was a great opportunity for us to do some testing on some specific gamification concepts with a set of business analysts.  We pulled in 8 folks for a focus group on gamification concepts and whether they thought those would work for their teams. To get ready for this, my designer extraordinaire, Andrea Cantú, flew into town and we spent almost a week locked in a room together brainstorming design ideas.  We killed a few trees trying to get all of our concepts and other examples together in the process, but in the end, we put together a whole series of examples of how you might gamify an Oracle app (in this case, CRM).  Andrea is a genius for this kind of thing and the comps she created looked great.  Here's a picture of her hard at work!  We also had the good fortune to have my boss, Laurie Pattison and my usability contractor, Shobana Subramanian there to note take and observe as well.  Here's a few shots of us, hard at work preparing for the day (or checking out something on Laurie's iPhone...) To start things off, we gave an overview of gamification and I talked about what it's used for.  Then we gave the participants a scenario about our sales person and what we were trying to get her to do. It was a great opportunity to highlight what our business goals might be and why we might want to add game mechanics.  It was also a good way to get them thinking about how that might work for them in their environments and workplaces. There were some surprises for the day.  We asked how many of them were already familiar with the concept of gamification--only two people had heard of it and only one was using game mechanics in his work.  That's in contrast to a survey we just ran internally with folks in a dev org where almost 50% of about 450 respondents had heard of gamification.  As we discussed the ways game mechanics could be used, it became clear that many of the folks had seen some game mechanics in action but didn't know that's what they were.  We also noticed that the folks in this group felt that if they were trying to sell the concept in their orgs, they wouldn't call it gamification.  That's not a huge surprise to me--they said what we've heard in the past, that gamification does not seem like a serious term for enterprise software.  They said they'd sell it with the goals--as a means to increase behaviors by rewarding users for activities.  It's a funny problem.  The word puts some folks off, but at the same time, I haven't seen another one word description that quite captures the range of things that "gamification" can cover.  My guess is that the more mainstream the term becomes, the more desensitized we'll become to the idea the it's trivializing enterprise software in some way.  Still, it was interesting to note that this group still felt that they would not take this concept to their bosses or teams and call it "gamification".  They focused on the goals, and how we could incentivize desired behaviors with game mechanics.  As I have already stated in other posts, I feel like my org is more receptive to discussing how this is just a more transparent type of usability and user experience methods than talking about gamification.  That's the argument they said they would use. All in all, it was a good session.  I love getting to talk to customers, present ideas and concepts, and get their feedback and input.  It's the type of thing that really helps drive our designs and keeps us grounded in what our customers need/want.  We're already planning where to get more feedback opportunities in the coming months.

  • Android Java rectangle collision detection not working

    - by Charlton Santana
    I had been hard coding a collision detection system which was buggy. Then I came across using rectangles for collsion detection. So I put it all in and it does not work, I put a log in and it never logged. Note to Java programmers who are not Android programers: Android uses the word Rect instead of Rectangle. Code for Block.java: public Rect getBounds(){ return new Rect (this.x, this.y, 10, 20); } Code for Sprite.java: public Rect getBounds(){ return new Rect (this.x, this.y, 20, 20); } Code for MainGame.java: for(Block block : BLOCKS) { block.draw(canvas); block.rigidbody(); Rect spriter = sprite.getBounds(); Rect blockr = block.getBounds(); if(spriter.intersect(blockr)){ showgameover = 1; Log.d(TAG, "Game Over"); } } Is anyone able to help?

  • What is the politically correct way of refactoring other's code?

    - by dukeofgaming
    I'm currently working in a geographically distributed team in a big company. Everybody is just focused on today's tasks and getting things done, however this means sometimes things have to be done the quick way, and that causes problems... you know, same old, same old. I'm bumping into code with several smells such as: big functions pointless utility functions/methods (essentially just to save writing a word), overcomplicated algorithms, extremely big files that should be broken down into different files/classes (1,500+ lines), etc. What would be the best way of improving code without making other developers feel bad/wrong about any proposed improvements?

  • Disable ATI Radeon graphics card and use intel graphics (switcheroo unavailable)

    So I have a HP Envy with ATI Radeon 5450 + intel switchable graphics. I think (though I'm not sure) that the Radeon is running right now on Ubuntu 12.04 (because my laptop is making too much noise when I'm doing something non gpu intensive like word processing, or web browsing). So what I want to do is disable the ATI Radeon and use the Intel instead. I looked around and it seems all the solutions use switcheroo, but I dont have it on my computer! I think this happened because I tried installing the proprietary driver (fglrx). Any and all help is 200% appreciated, thank you

  • Session Report - Modern Software Development Anti-Patterns

    - by Janice J. Heiss
    In this standing-room-only session, building upon his 2011 JavaOne Rock Star “Diabolical Developer” session, Martijn Verburg, this time along with Ben Evans, identified and explored common “anti-patterns” – ways of doing things that keep developers from doing their best work. They emphasized the importance of social interaction and team communication, along with identifying certain psychological pitfalls that lead developers astray. Their emphasis was less on technical coding errors and more how to function well and to keep one’s focus on what really matters. They are the authors of the highly regarded The Well-Grounded Java Developer and are both movers and shakers in the London JUG community and on the Java Community Process. The large room was packed as they gave a fast-moving, witty presentation with lots of laughs and personal anecdotes. Below are a few of the anti-patterns they discussed.Anti-Pattern One: Conference-Driven DeliveryThe theme here is the belief that “Real pros hack code and write their slides minutes before their talks.” Their response to this anti-pattern is an expression popular in the military – PPPPPP, which stands for, “Proper preparation prevents piss-poor performance.”“Communication is very important – probably more important than the code you write,” claimed Verburg. “The more you speak in front of large groups of people the easier it gets, but it’s always important to do dry runs, to present to smaller groups. And important to be members of user groups where you can give presentations. It’s a great place to practice speaking skills; to gain new skills; get new contacts, to network.”They encouraged attendees to record themselves and listen to themselves giving a presentation. They advised them to start with a spouse or friends if need be. Learning to communicate to a group, they argued, is essential to being a successful developer. The emphasis here is that software development is a team activity and good, clear, accessible communication is essential to the functioning of software teams. Anti-Pattern Two: Mortgage-Driven Development The main theme here was that, in a period of worldwide recession and economic stagnation, people are concerned about keeping their jobs. So there is a tendency for developers to treat knowledge as power and not share what they know about their systems with their colleagues, so when it comes time to fix a problem in production, they will be the only one who knows how to fix it – and will have made themselves an indispensable cog in a machine so you cannot be fired. So developers avoid documentation at all costs, or if documentation is required, put it on a USB chip and lock it in a lock box. As in the first anti-pattern, the idea here is that communicating well with your colleagues is essential and documentation is a key part of this. Social interactions are essential. Both Verburg and Evans insisted that increasingly, year by year, successful software development is more about communication than the technical aspects of the craft. Developers who understand this are the ones who will have the most success. Anti-Pattern Three: Distracted by Shiny – Always Use the Latest Technology to Stay AheadThe temptation here is to pick out some obscure framework, try a bit of Scala, HTML5, and Clojure, and always use the latest technology and upgrade to the latest point release of everything. Don’t worry if something works poorly because you are ahead of the curve. Verburg and Evans insisted that there need to be sound reasons for everything a developer does. Developers should not bring in something simply because for some reason they just feel like it or because it’s new. They recommended a site run by a developer named Matt Raible with excellent comparison spread sheets regarding Web frameworks and other apps. They praised it as a useful tool to help developers in their decision-making processes. They pointed out that good developers sometimes make bad choices out of boredom, to add shiny things to their CV, out of frustration with existing processes, or just from a lack of understanding. They pointed out that some code may stay in a business system for 15 or 20 years, but not all code is created equal and some may change after 3 or 6 months. Developers need to know where the code they are contributing fits in. What is its likely lifespan? Anti-Pattern Four: Design-Driven Design The anti-pattern: If you want to impress your colleagues and bosses, use design patents left, right, and center – MVC, Session Facades, SOA, etc. Or the UML modeling suite from IBM, back in the day… Generate super fast code. And the more jargon you can talk when in the vicinity of the manager the better.Verburg shared a true story about a time when he was interviewing a guy for a job and asked him what his previous work was. The interviewee said that he essentially took patterns and uses an approved book of Enterprise Architecture Patterns and applied them. Verburg was dumbstruck that someone could have a job in which they took patterns from a book and applied them. He pointed out that the idea that design is a separate activity is simply wrong. He repeated a saying that he uses, “You should pay your junior developers for the lines of code they write and the things they add; you should pay your senior developers for what they take away.”He explained that by encouraging people to take things away, the code base gets simpler and reflects the actual business use cases developers are trying to solve, as opposed to the framework that is being imposed. He told another true story about a project to decommission a very long system. 98% of the code was decommissioned and people got a nice bonus. But the 2% remained on the mainframe so the 98% reduction in code resulted in zero reduction in costs, because the entire mainframe was needed to run the 2% that was left. There is an incentive to get rid of source code and subsystems when they are no longer needed. The session continued with several more anti-patterns that were equally insightful.

  • Maximized Office 2007 gets cut off on multi-monitor setup with different resolutions

    - by Adam M-W
    I've got an external monitor plugged into my laptop that I like to use for typing up documents, but I've noticed that when Word is maximized it gets cut off at where the primary monitor's bounds are. Is this a bug in Wine (i'm using version 1.3.32), or with my Window Manager (metacity with compositing enabled, version 2.34.1), with my graphics drivers (nouveau) or something else? I know that I can fix it by unmaximizing (it doesn't get cut off and I can resize to the entirety of the second monitor), but it keeps on maximizing itself as it (rightly so) knows that it should be taking up the entire screen. I don't really want to use the "Emulate a virtual desktop feature", I would prefer to find the source of this issue.

  • XBRL - Moving from Production to Consumption

    - by jmorourke
    Here's an update on what’s new with XBRL and how it can actually benefit your organization versus adding extra time and costs to financial reporting.  On February 29th (leap day) of 2012 I attended the XBRL and Financial Analysis Technology Conference at Baruch College in NYC.  The event, which attracted over 300 XBRL gurus and fans was presented by XBRL US, The New York Society of Security Analysts’ Improved Corporate Reporting Committee, and Baruch College’s Robert Zicklin Center for Corporate Integrity.  The event featured keynotes from the U.S. Securities and Exchange Commission (SEC), and the CFA Institute as well as panels covering alternative research tools and data, corporate reporting to stakeholders and a demonstration of XBRL analysis tools.  The program culminated in a presentation of the finalists and the winner of the $20,000 XBRL Challenge.    Some of the key points made in the sessions included: The focus of XBRL tools is moving from production to consumption. As of February 2012, over 9000 companies are reporting in XBRL, with over 10 million facts filed to date XBRL taxonomy extensions have dropped from 27% to 11% making comparisons easier The SEC reports that XBRL makes it easier to analyze disclosures, focus on accounting issues XBRL is helping standards-setters like the FASB speed their analysis of impacts of proposed accounting rule changes Companies like Thomson Reuters report that XBRL is helping speed the delivery of data to clients The most interesting part of the program though, was the session highlighting the 5 finalists in the XBRL Challenge competition and the winning solution.  The XBRL Challenge was launched in 2011 as a means of spurring the development of more end-user tools to help with the consumption of XBRL-based financial information.       Over an 8-month process handled by 5 judges, there were 84 registrants, 15 completed submissions, 5 finalists and one winner of the challenge.  All of the solutions are open-sourced tools and most of them focus on consuming XBRL-based data.  The 5 finalists included: Advanced XBRL Processing from Oxide solutions – XBRL viewer for taxonomies, filings and company data with peer comparison capabilities. Arrelle – API for XBRL processes, supports SEC Validations, RSS Feeds to access filings etc. Calcbench – XBRL data analysis tool that can be embedded in other web applications.  This tool can combine XBRL filings with real-time market data. XBRL to XL – allows the importing of XBRL data into Microsoft Excel for analysis, comparisons.  Users start on the web and populate Excel with XBRL data. XBurble – allows users to search and view XBRL filings, export to Excel, merge for comparison, and includes a workflow interface. The winner of the $20,000 XBRL Challenge prize was CalcBench.  More information about the XBRL Challenge and the finalists can be found at www.XBRLUS.org/challenge XBRL for Sustainability Reporting – other recent news on the XBRL front was the announcement by the Global Reporting Initiative (GRI) of an XBRL taxonomy for Sustainability Reporting.  This taxonomy was co-developed by the GRI and Deloitte and is designed to make the consumption of data found in Sustainability Reports much easier.  Although there is no government mandate to file Sustainability Reports in XBRL format, organizations that do use the GRI guidelines for Sustainability Reporting are encouraged to tag and submit their data voluntarily to the GRI – who will populate a database with Sustainability Reporting data and make this available to the public.  For more information about this initiative, you can go to the GRI web site:  www.globalreporting.org. So how does all of this benefit corporate filers and investors?  Since its introduction, the consensus in the market is that XBRL has mainly benefited the regulators and investment analysts who need to consume and analyze large volumes of financial data.  But with the emergence of more end-user tools for consuming and analyzing XBRL-based data, and the ability to perform quick comparisons of one company versus its peers and competitors in an industry group, will soon accelerate the benefits to corporate finance staff, as well as individual investors.  This could apply to financial results tagged in XBRL, as well as non-financial information such as Sustainability Reporting – which over the long-term will likely be integrated with financial reporting.   And as multiple regulators and agencies in a country adopt the XBRL standard for corporate filings, more benefits will accrue as companies will be able to leverage one set of XBRL-based financial data for multiple regulatory filings.     For more information about the latest developments in XBRL, check out the XBRL US or XBRL International web sites:  www.xbrl.org, www.xbrlus.org.

  • SEO domain name advice

    - by Dominykas Mostauskis
    I'm starting a website, that is meant for a non-English region, using an alphabet that is a bit different than that of English. Current plan is as follows. The website name, and the domain name, will be in the local language (not English); however, domain name will be spelled in the English alphabet, while the website's title will be the same word(s), but spelled properly with accents. E.g.: 'www.litterat.fr' and 'Littérat'. Does the difference between domain name and website name character use influence the site's SEO? Is it better, SEO-wise, to choose a name that can be spelled the same way in the English alphabet? From my experience, when searching online, invariably, the English alphabet is used, no matter the language, so people will still be searching 'litterat' (without accents and such).
