  • Digital Agenda in the EU means open standards after all

    - by trond-arne.undheim
    European Commission Vice President Neelie Kroes speech on Openness at the heart of the EU Digital Agenda at Open Forum Europe 2010 Summit in Brussels refocuses the EU Digital Agenda on open standards. I say the speech scores a 90/100, smooth, smart, a little vicious at the fringes, maybe? Anyway, it shows the strategy might age and implement well. This is Dutch pragmatism at its best. The EU Digital Agenda (I give it an 85/100 score), while laudable, stops short of using the term. The next step for the European Commission is defining the term open standards. If they do that, and do it right, Vice President Kroes will go into history as having made a significant contribution towards global progress in e-government by possibly eradicating lock-in forever. Moreover, she will put Europe's SMEs in a better position to succeed in a global IT market filled with barriers to entry from players not fully understanding, using, or unpacking standards. Kroes' interesting suggestion that she will now explore a "legal proposal" on interoperability that will have an impact on all IT companies operating in the European market is more up for debate. An interoperability directive? One run by DG COMP or one run by DG INFSO, telecom style? Would something like that work? Would the industry like it? Would it help European governments? Possibly, if done right. The good thing was, Kroes pointed out that she will look for input from the industry. Kroes' track record is one of not being scared of taking on the Titans. She also wants to enact real, positive, lasting change. "I will not go anywhere", she said. All of that is good. And she does understand the importance of open standards. Let's now start discussing the details. Implementing the Digital Agenda is not simple. It requires collaboration across the various Directorates in the European Commission. Mounting a new Interoperability directive is also never attempted before. Getting it right is important. Even possibly finding out it cannot be done right and choosing a more light weight approach that is equally effective would be bold. Go Kroes!

  • What's your advise on a potential legal suit? [closed]

    - by ohho
    I [xxx app developer] received an email from Apple that a developer [of yyy app] believes I am "infringing their copyright." Description of Issue: [xxx developer] copied my application (my application is [yyy]) feature by feature. Even their donation model is completely copied from my application. Their first release was significantly later than mine, which implies copying of the application rather than parallel development. I suffered significant financial losses because of their actions, in additional to promotion problems as many people are confused with their product. My advertising was based around the idea of a "free [yyy] application for an iPhone" and they have just taken that as a title for their application. I would appreciate if someone takes a look at their release schedule and compare it to my releases. Additionally, please take a look at their functionality and how it point by point copies the functionality of my older releases. I am asking Apple to remove their application from the App Store, and ban them from resubmitting it. Thank you for your time! [yyy developer], the developer of the [yyy] application. My response was: The code of [xxx] is written by myself, using Apple public API. The graphics elements are designed by myself. The user interface and app control are independently designed and different from other [similar type] apps (please judge yourself). In-app Purchase is iOS Apple standard API. iAd is Apple iOS standard API. I don't think features can be owned exclusively. In fact, my app comes with fewer features, as I prefer minimalist design. I don't think idea can be owned exclusively. Apple responded: Thank you for your response. Unfortunately, Apple cannot serve as arbiter for disputes among third parties. Please contact [yyy developer] directly regarding your actions. You can reach [yyy developer] through: [...]. We look forward to confirmation from both parties that this issue has been resolved. If this issue is not resolved shortly, Apple may be forced to pull your application(s) from the App Store. Then I sent my response above to [yyy developer]. [yyy developer] then asked me "to provide (my) legal address and contact details that (his) lawyer requires to file a copyright infringement suit." IMO, I don't think the [yyy developer]'s claim on "feature by feature" copy is valid. I have fewer features, completely different user interface design. However, I don't think I can afford a legal action for an app of so little financial return. So what's your advise on this? Should I just let Apple pull my app? Or is there any alternative I can consider? FYI ... UI of [xxx app]: and UI of [yyy app]:

  • Keeping up with New Releases

    - by Jeremy Smyth
    You can keep up with the latest developments in MySQL software in a number of ways, including various blogs and other channels. However, for the most correct (if somewhat dry and factual) information, you can go directly to the source.  Major Releases  For every major release, the MySQL docs team creates and maintains a "nutshell" page containing the significant changes in that release. For the current GA release (whatever that is) you'll find it at this location: https://dev.mysql.com/doc/mysql/en/mysql-nutshell.html  At the moment, this redirects to the summary notes for MySQL 5.6. The notes for MySQL 5.7 are also available at that website, at the URL http://dev.mysql.com/doc/refman/5.7/en/mysql-nutshell.html, and when eventually that version goes GA, it will become the currently linked notes from the URL shown above. Incremental Releases  For more detail on each incremental release, you can have a look at the release notes for each revision. For MySQL 5.6, the release notes are stored at the following location: http://dev.mysql.com/doc/relnotes/mysql/5.6/en/ At the time I write this, the topmost entry is a link for MySQL 5.6.15. Each linked page shows the changes in that particular version, so if you are currently running 5.6.11 and are interested in what bugs were fixed in versions since then, you can look at each subsequent release and see all changes in glorious detail. One really clever thing you can do with that site is do an advanced Google search to find exactly when a feature was released, and find out its release notes. By using the preceding link in a "site:" directive in Google, you can search only within those pages for an entry. For example, the following Google search shows pages within the release notes that reference the --slow-start-timeout option:     site:http://dev.mysql.com/doc/relnotes/mysql/ "--slow-start-timeout" By running that search, you can see that the option was added in MySQL 5.6.5 and also rolled into MySQL 5.5.20.   White Papers Also, with each major release you can usually find a white paper describing what's new in that release. In MySQL 5.6 there was a "What's new" whitepaper at this location: http://www.mysql.com/why-mysql/white-papers/whats-new-mysql-5-6/ You'll find other white papers at: http://www.mysql.com/why-mysql/white-papers/ Search the page for "5.6" to see any papers dealing specificallly with that version.

It’s no secret that complex, large-scale projects need close management controls to ensure that they’re delivered on time and on budget. But now there’s growing evidence that failing to meet these goals can have far-reaching consequences, not only for the reputations and value of individual organizations but also for the tenure of their top executives. Government watchdogs forced one large contractor to suspend a multibillion-dollar defense program—and delay payment receipts—until a better management system was launched to more accurately track spending, project milestones, and other fundamental metrics. Significant delays in the opening of the £4.3 billion Terminal 5 at Heathrow Airport impaired an airline’s operations and contributed to a drop in its share prices. These real-world examples are noteworthy because of the huge financial risks they created. They’re also far from being isolated cases. Research by the Economist Intelligence Unit found that only 11 percent of companies claimed they delivered expected ROI on major capital projects 90 percent of the time or more. In addition, 12 percent of respondents said they achieved planned ROI less than half the time. According to Phil Thornton, lead consultant at the analyst firm Clarity Economics, the numbers demonstrate obvious challenges related to managing risks, accurately predicting ROI, and consistently delivering bottom-line growth for major capital investments “Portfolio management is a path to improve your organization’s competitive advantage. It helps make sure your organization is investing in the right things and not spending its time on things that are not delivering the intended results for the firm.” Read the full article here

  • MySQL and Hadoop Integration - Unlocking New Insight

    - by Mat Keep
    “Big Data” offers the potential for organizations to revolutionize their operations. With the volume of business data doubling every 1.2 years, analysts and business users are discovering very real benefits when integrating and analyzing data from multiple sources, enabling deeper insight into their customers, partners, and business processes. As the world’s most popular open source database, and the most deployed database in the web and cloud, MySQL is a key component of many big data platforms, with Hadoop vendors estimating 80% of deployments are integrated with MySQL. The new Guide to MySQL and Hadoop presents the tools enabling integration between the two data platforms, supporting the data lifecycle from acquisition and organisation to analysis and visualisation / decision, as shown in the figure below The Guide details each of these stages and the technologies supporting them: Acquire: Through new NoSQL APIs, MySQL is able to ingest high volume, high velocity data, without sacrificing ACID guarantees, thereby ensuring data quality. Real-time analytics can also be run against newly acquired data, enabling immediate business insight, before data is loaded into Hadoop. In addition, sensitive data can be pre-processed, for example healthcare or financial services records can be anonymized, before transfer to Hadoop. Organize: Data is transferred from MySQL tables to Hadoop using Apache Sqoop. With the MySQL Binlog (Binary Log) API, users can also invoke real-time change data capture processes to stream updates to HDFS. Analyze: Multi-structured data ingested from multiple sources is consolidated and processed within the Hadoop platform. Decide: The results of the analysis are loaded back to MySQL via Apache Sqoop where they inform real-time operational processes or provide source data for BI analytics tools. So how are companies taking advantage of this today? As an example, on-line retailers can use big data from their web properties to better understand site visitors’ activities, such as paths through the site, pages viewed, and comments posted. This knowledge can be combined with user profiles and purchasing history to gain a better understanding of customers, and the delivery of highly targeted offers. Of course, it is not just in the web that big data can make a difference. Every business activity can benefit, with other common use cases including: - Sentiment analysis; - Marketing campaign analysis; - Customer churn modeling; - Fraud detection; - Research and Development; - Risk Modeling; - And more. As the guide discusses, Big Data is promising a significant transformation of the way organizations leverage data to run their businesses. MySQL can be seamlessly integrated within a Big Data lifecycle, enabling the unification of multi-structured data into common data platforms, taking advantage of all new data sources and yielding more insight than was ever previously imaginable. Download the guide to MySQL and Hadoop integration to learn more. I'd also be interested in hearing about how you are integrating MySQL with Hadoop today, and your requirements for the future, so please use the comments on this blog to share your insights.

  • Binary on the Coat of Arms of the Governor General of Canada

    - by user132636
    Can you help me further this investigation? Here is about 10% of the work I have done on it. I present it only to see if there are any truly curious people among you. I made a video a few weeks ago showing some strange things about the Governor General's Coat of Arms and the binary on it. Today, I noticed something kinda cool and thought I would share. Here is the binary as it appears on the COA: 110010111001001010100100111010011 As DEC: 6830770643 (this is easily found on the web) Take a close look at that number. What do you notice about it? It has a few interesting features, but here is the one no one has pointed out... Split it down the middle and you have 68307 70643. The first digit is double the value of the last digit. The second digit is double the second last digit. The third digit is half of the third to last digit. And the middle ones are even or neutral. At first, I thought of it as energy. ++-nnnn+-- But actually you can create something else with it using the values. 221000211. See how that works. You may be asking why that is significant. Bare with me. I know 99% are rolling their eyes. 221000211 as base3 gives you this as binary: 100011101000111 100011101000111 as HEX is 4747, which converts to "GG". Initials of Governor General. GG.ca is his website. When you convert to base 33 (there are 33 digits in the original code) you get "GOV" Interesting? :D There is a lot more to it. I'll continue to show some strange coincidences if anyone is interested. Sorry if I am not explaining this correctly. By now you have probably figured out that I have no background in this. Which is why I am here. Thank you.

  • Oracle ERP Cloud Solution Defines Revenue Recognition Software Market

    - by Steve Dalton
    Normal 0 false false false EN-US X-NONE X-NONE Revenue is a fundamental yardstick of a company's performance, and one of the most important metrics for investors in the capital markets. So it’s no surprise that the accounting standard boards have devoted significant resources to this topic, with a key goal of ensuring that companies use a consistent method of recognizing revenue. Due to the myriad of revenue-generating transactions, and the divergent ways organizations recognize revenue today, the IFRS and FASB have been working for 12 years on a common set of accounting standards that apply to all industries in virtually all countries. Through their joint efforts on May 28, 2014 the FASB and IFRS released the IFRS 15 / ASU 2014-9 (Revenue from Contracts with Customers) converged accounting standard. This standard applies to revenue in all public companies, but heavily impacts organizations in any industry that might have complex sales contracts with multiple distinct deliverables (obligations). For example, an auto dealer who bundles free service with the sale of a car can only recognize the service revenue once the owner of the car brings it in for work. Similarly, high-tech companies that bundle software licenses, consulting, and support services on a sales contract will recognize bundled service revenue once the services are delivered. Now all companies need to review their revenue for hidden bundling and implicit obligations. Numerous time-consuming and judgmental activities must be performed to properly recognize revenue for complex sales contracts. To illustrate, after the contract is identified, organizations must identify and examine the distinct deliverables, determine the estimated selling price (ESP) for each deliverable, then allocate the total contract price to each deliverable based on the ESPs. In terms of accounting, organizations must determine whether the goods or services have been delivered or performed to the customer’s satisfaction, then either book revenue in the current period or record a liability for the obligation if revenue will be recognized in a future accounting period. Oracle Revenue Management Cloud was architected and developed so organizations can simplify and streamline revenue recognition. Among other capabilities, the solution uses business rules to efficiently identify and examine contracts, intelligently calculate and allocate deliverable prices based on prescribed inputs, and accurately recognize revenue for each deliverable based on customer satisfaction. "Oracle works very closely with our customers, the Big 4 accounting firms, and the accounting standard boards to deliver an adaptive, comprehensive, new generation revenue recognition solution,” said Rondy Ng, Senior Vice President, Applications Development. “With the recently announced IFRS 15 / ASU 2014-9, Oracle is ready to support customer adoption of the new standard with our Revenue Management Cloud,” said Rondy. Oracle Revenue Management Cloud, an integral part of Oracle Financials Cloud, helps organizations comply with accounting standards, provides them with confidence that reported revenue is materially accurate, and simplifies the accounting process for revenue recognition. Stay tuned to this blog for regular updates on Oracle Revenue Management Cloud. We also invite you to review our new oracle.com ERP pages @ oracle.com/erp. We will be updating these pages very soon with more information about Oracle Revenue Management Cloud.

  • Source of (programmer) inefficiency

    - by Daniel
    I am interested to gain a better insight about the possible reasons of personal inefficiency as programmers (and only in programming) due to – simply - our own errors (because we are humans – well, almost all of us). I am not interested in how much we are productive or in how many adjustements the customer asks for when the work is done, but where and how each of us spend that part of its time in tasks that are unproductive and there is no one to blame except ourselves. Excluding ego - feeding and / or self – gratification, what I am trying to get (for all of us) is: what are the common issues eating our time; insight on reasons for that issues; identify simple way for us, personally (not delegating actions to other or our organizations), to correct our own problems. Please, do not think in academic terms but aim at the opportunity to compare our daily experiences and understand what are and how we try to fix our personal deficiencies. If you are interested to respond to this post, please: integrate the list if you see something important (or obvious) missing; highlight or name honestly your first issue tellng the way you try to address and solve your issue acting on yourself and yourself only in a sort of "continuous quality improving" My criteria for accepting the answer is: choose the best solution (feasibility and utility) to fix one (or more) of the problems of the list. Of course, selecting an error is not a vote on our skills: maybe we are hyper professional programmers and we lose ten minutes only every year or we are terribly inefficient, losing a couple of days a week: reasons for inefficiency could be really the same - but in a different scale. A possible list: Plain error in the names (variables, functions). Inability to see the obvious in your code. Misreading. Lack of concentration. Trying to use a technology you have not mastered. Errors with data types. Time required to understand your previous code or your documentation. Trying to do something more than requested because you enjoy it Using solutions more complicated than required because you enjoy it. Plain logical errors. Errors due to your fault in communications. Distraction My first personal issue: "Trying to use a technology you do not master." I have to use daily several technologies and I often need to spend significant time correcting code because my assumptions were plainly wrong. Reasons for this: production needs put high pressure and make difficult to find the time to learn. I try to address this reading technical books - as many as I can - even if this actually consumes a lot of time.

  • New Options for MySQL High Availability

    - by Mat Keep
    Data is the currency of today’s web, mobile, social, enterprise and cloud applications. Ensuring data is always available is a top priority for any organization – minutes of downtime will result in significant loss of revenue and reputation. There is not a “one size fits all” approach to delivering High Availability (HA). Unique application attributes, business requirements, operational capabilities and legacy infrastructure can all influence HA technology selection. And then technology is only one element in delivering HA – “People and Processes” are just as critical as the technology itself. For this reason, MySQL Enterprise Edition is available supporting a range of HA solutions, fully certified and supported by Oracle. MySQL Enterprise HA is not some expensive add-on, but included within the core Enterprise Edition offering, along with the management tools, consulting and 24x7 support needed to deliver true HA. At the recent MySQL Connect conference, we announced new HA options for MySQL users running on both Linux and Solaris: - DRBD for MySQL - Oracle Solaris Clustering for MySQL DRBD (Distributed Replicated Block Device) is an open source Linux kernel module which leverages synchronous replication to deliver high availability database applications across local storage. DRBD synchronizes database changes by mirroring data from an active node to a standby node and supports automatic failover and recovery. Linux, DRBD, Corosync and Pacemaker, provide an integrated stack of mature and proven open source technologies. DRBD Stack: Providing Synchronous Replication for the MySQL Database with InnoDB Download the DRBD for MySQL whitepaper to learn more, including step-by-step instructions to install, configure and provision DRBD with MySQL Oracle Solaris Cluster provides high availability and load balancing to mission-critical applications and services in physical or virtualized environments. With Oracle Solaris Cluster, organizations have a scalable and flexible solution that is suited equally to small clusters in local datacenters or larger multi-site, multi-cluster deployments that are part of enterprise disaster recovery implementations. The Oracle Solaris Cluster MySQL agent integrates seamlessly with MySQL offering a selection of configuration options in the various Oracle Solaris Cluster topologies. Putting it All Together When you add MySQL Replication and MySQL Cluster into the HA mix, along with 3rd party solutions, users have extensive choice (and decisions to make) to deliver HA services built on MySQL To make the decision process simpler, we have also published a new MySQL HA Solutions Guide. Exploring beyond just the technology, the guide presents a methodology to select the best HA solution for your new web, cloud and mobile services, while also discussing the importance of people and process in ensuring service continuity. This is subject recently presented at Oracle Open World, and the slides are available here. Whatever your uptime requirements, you can be sure MySQL has an HA solution for your needs Please don't hesitate to let us know of your HA requirements in the comments section of this blog. You can also contact MySQL consulting to learn more about their HA Jumpstart offering which will help you scope out your scaling and HA requirements.

  • What constitutes a "substantial, good-faith effort to remove the links"

    - by Luke McCallum
    We engaged the services of a 3rd party SEO consultant to assist us in managing our Meta data and to write regular blogs on our site http://cyberdesignworks.com.au Without our authorisation, the SEO also ran a link building campaign which has seen us Penguin slapped and we no longer appear in Google for a number of our core keywords. Since notification by Google that we have "unnatural links" back in March we have undertaken a significant campaign to rid ourselves of these dodgy backlinks by a number of methods. I have just received feedback on my 4th or 5th resubmission which is still advising that we need to make a "substantial, good-faith effort to remove the links" before Google will reconsider us for inclusion. After the effort that I have gone through to get links removed, I am now at a loss as to what else I can do to demonstrate "substantial, good-faith effort to remove the links". Below is a summary of the actions that we have taken to date. According to http://removem.com we had about 5584 back-linking domains. Of those we have successfully contacted and had removed links from 344 domains We ignored links from 625 domains as they were either legitimate press releases, natural backlinks or client websites containing an attribution link in the footer that points back to us. Due to our efforts, or the sites simply becoming defunct, removem.com reports that links from 3262 domains have been removed. We have contacted but are yet to receive feedback from 1666 domains so we can assume that the backlinks remain. We have configured an automatic 301 redirect for each of the links from these 1666 domains to point to http://redirects.sanscode.com/ which we are calling our Bad Link Catcher (a stroke of genius I thought). i.e http://www.mysimplewebdesign.com/create-a-perfect-webpage-with-four-important-tips-from-sydney-web-development-service-companies.php As we are a web design agency, we have a large number of client websites which contain an attribution link in their footer which points back to us. We have gone through the vast majority of these and updated these links to replace anchor text with an image and rel="nofollow" link. i.e <a rel="nofollow" target="_blank" href="http://www.cyberdesignworks.com.au/"><img src="https://sessions.sanscode.com/site/assets/media/badges/Badge_CDW_SANSCODE.png"></a> See http://www.milkatwork.com.au/ An export from http://removem.com detailing the number of times we have contacted each link and whether it is still found or not was also supplied with each resubmission. The total back links reported in Google Web Master Tools has dropped from over 100K to 87K and I expect it to drop significantly lower once Google re-crawls each back-linking page. Based on all of the above, I am not sure what else I can do to to demonstrate a "substantial, good-faith effort to remove the links". I would sincerely appreciate any feedback or suggestions that you may have as I am out of ideas.

  • Extensible Metadata in Oracle IRM 11g

    Another significant change in Oracle IRM 11g is that we now use XML to create the tamperproof header for each sealed document. This article explains what this means, and what benefit it offers. So, every sealed file has a metadata header that contains information about the document - its classification, its format, the user who sealed it, the name and URL of the IRM Server, and much more. The IRM Desktop and other IRM applications use this information to formulate the request for rights, as well as to enhance the user experience by exposing some of the metadata in the user interface. For example, in Windows explorer you can see some metadata exposed as properties of a sealed file and in the mouse-over tooltip. The following image shows 10g and 11g metadata side by side. As you can see, the 11g metadata is written as XML as opposed to the simple delimited text format used in 10g. So why does this matter? The key benefit of using XML is that it creates the opportunity for sealing applications to use custom metadata. This in turn creates the opportunity for custom classification models to be defined and enforced. Out of the box, the solution uses the context classification model, in which two particular pieces of metadata form the basis of rights evaluation - the context name and the document's item code. But a custom sealing application could use some other model entirely, enabling rights decisions to be evaluated on some other basis. The integration with Oracle Beehive is a great example of this. When a user adds a document to a Beehive workspace, that document can be automatically sealed with metadata that represents the Beehive security model rather than the context model. As a consequence, IRM can enforce the Beehive security model precisely and all rights configuration can actually be managed through the Beehive UI rather than the IRM UI. In this scenario, IRM simply supports the Beehive application, seamlessly extending Beehive security to all copies of workspace documents without any additional administration. Finally, I mentioned that the metadata header is tamperproof. This is obviously to stop a rogue user modifying the metadata with a view to gaining unauthorised access - reclassifying a board document to a less sensitive classifcation, for example. To prevent this, the header is digitally signed and can only be manipulated by a suitably authorised sealing application.

  • A Community Cure for a String Splitting Headache

    - by Tony Davis
    A heartwarming tale of dogged perseverance and Community collaboration to solve some SQL Server string-related headaches. Michael J Swart posted a blog this week that had me smiling in recognition and agreement, describing how an inquisitive Developer or DBA deals with a problem. It's a three-step process, starting with discomfort and anxiety; a feeling that one doesn't know as much about one's chosen specialized subject as previously thought. It progresses through a phase of intense research and learning until finally one achieves breakthrough, blessed relief and renewed optimism. In this case, the discomfort was provoked by the mystery of massively high CPU when searching Unicode strings in SQL Server. Michael explored the problem via Stack Overflow, Google and Twitter #sqlhelp, finally leading to resolution and a blog post that shared what he learned. Perfect; except that sometimes you have to be prepared to share what you've learned so far, while still mired in the phase of nagging discomfort. A good recent example of this recently can be found on our own blogs. Despite being a loud advocate of the lightning fast T-SQL-based string splitting techniques, honed to near perfection over many years by Jeff Moden and others, Phil Factor retained a dogged conviction that, in theory, shredding element-based XML using XQuery ought to be even more efficient for splitting a string to create a table. After some careful testing, he found instead that the XML way performed and scaled miserably by comparison. Somewhat subdued, and with a nagging feeling that perhaps he was still missing "something", he posted his findings. What happened next was a joy to behold; the community jumped in to suggest subtle changes in approach, using an attribute-based rather than element-based XML list, and tweaking the XQuery shredding. The result was performance and scalability that surpassed all other techniques. I asked Phil how quickly he would have arrived at the real breakthrough on his own. His candid answer was "never". Both are great examples of the power of Community learning and the latter in particular the importance of being brave enough to parade one's ignorance. Perhaps Jeff Moden will accept the string-splitting gauntlet one more time. To quote the great man: you've just got to love this community! If you've an interesting tale to tell about being helped to a significant breakthrough for a problem by the community, I'd love to hear about it. Cheers, Tony.

  • Closing the Gap: 2012 IOUG Enterprise Data Security Survey

    - by Troy Kitch
    The new survey from the Independent Oracle Users Group (IOUG) titled "Closing the Security Gap: 2012 IOUG Enterprise Data Security Survey," uncovers some interesting trends in IT security among IOUG members and offers recommendations for securing data stored in enterprise databases. "Despite growing threats and enterprise data security risks, organizations that implement appropriate detective, preventive, and administrative safeguards are seeing significant results," finds the report's author, Joseph McKendrick, analyst, Unisphere Research. Produced by Unisphere Research and underwritten by Oracle, the report is based on responses from 350 IOUG members representing a variety of job roles, organization sizes, and industry verticals. Key findings include Corporate budgets increase, but trailing. Though corporate data security budgets are increasing this year, they still have room to grow to reach the previous year’s spending. Additionally, more than half of respondents say their organizations still do not have, or are unaware of, data security plans to help address contingencies as they arise. Danger of unauthorized access. Less than a third of respondents encrypt data that is either stored or in motion, and at the same time, more than three-fifths say they send actual copies of enterprise production data to other sites inside and outside the enterprise. Privileged user misuse. Only about a third of respondents say they are able to prevent privileged users from abusing data, and most do not have, or are not aware of, ways to prevent access to sensitive data using spreadsheets or other ad hoc tools. Lack of consistent auditing. A majority of respondents actively collect native database audits, but there has not been an appreciable increase in the implementation of automated tools for comprehensive auditing and reporting across databases in the enterprise. IOUG RecommendationsThe report's author finds that securing data requires not just the ability to monitor and detect suspicious activity, but also to prevent the activity in the first place. To achieve this comprehensive approach, the report recommends the following. Apply an enterprise-wide security strategy. Database security requires multiple layers of defense that include a combination of preventive, detective, and administrative data security controls. Get business buy-in and support. Data security only works if it is backed through executive support. The business needs to help determine what protection levels should be attached to data stored in enterprise databases. Provide training and education. Often, business users are not familiar with the risks associated with data security. Beyond IT solutions, what is needed is a well-engaged and knowledgeable organization to help make security a reality. Read the IOUG Data Security Survey Now.

  • Get to Know a Candidate (12 of 25): Andre Barnett&ndash;Reform Party

    - by Brian Lanham
    DISCLAIMER: This is not a post about “Romney” or “Obama”. This is not a post for whom I am voting. Information sourced for Wikipedia. Barnett is an American politician and entrepreneur. He is the founder of the information technology (IT) company WiseDome Inc.  Barnett was born in Zanesville, Ohio in 1976. He attended Austin Peay State University and Western Governors University.  A former member of the United States Armed Forces, Barnett served in Sarajevo before being wounded in a helicopter accident.  Following his military service, Barnett became a fitness model in New York. In 2001, he founded WiseDome Incorporated, an IT company that provides information technology and data recovery services. Reform Party of the United States of America (RPUSA), generally known as the Reform Party USA or the Reform Party, is a political party in the United States, founded in 1995 by Ross Perot. Perot said Americans were disillusioned with the state of politics—as being corrupt and unable to deal with vital issues—and desired a viable alternative to the Republican and Democratic Parties. The party has nominated different candidates over the years, such as founder Ross Perot, Pat Buchanan, and Ralph Nader. The party's most significant victory came when Jesse Ventura was elected governor of Minnesota in 1998. Since then, the party has been torn by infighting and disagreements, which it seeks to overcome. The Reform Party platform includes the following: * Maintaining a balanced budget, ensured by passing a Balanced Budget Amendment and changing budgeting practices, and paying down the federal debt * Campaign finance reform, including strict limits on campaign contributions and the outlawing of the Political action committee * Enforcement of existing immigration laws and opposition to illegal immigration * Opposition to free trade agreements like the North American Free Trade Agreement and Central America Free Trade Agreement, and a call for withdrawal from the World Trade Organization * Term limits on U.S. Representatives and Senators * Direct election of the United States President by popular vote * Federal elections held on weekends A noticeable absence from the Reform Party platform has been social issues, including abortion and gay rights. Reform Party representatives had long stated beliefs that their party could bring together people from both sides of these issues, which they consider divisive, to address what they considered to be more vital concerns as expressed in their platform. The idea was to form a large coalition of moderates; that intention was overridden in 2001 by the Buchanan takeover which rewrote the RPUSA Constitution to specifically include platform planks opposed to any form of abortion. The Buchananists, in turn, were overridden by the 2002 Convention which specifically reverted the Constitution to its 1996 version and the party's original stated goals. Barnett has Ballot Access in: FL Learn more about Andre Barnett and Reform Party on Wikipedia.

  • Good Scoop: The PeopleSoft/IBM Backstory

    - by [email protected]
    Sometimes you're searching for something online and you find an unrelated, bonus nugget. Last week I stumbled across an interesting blog post from Chris Heller of a PeopleSoft consulting shop in San Ramon, CA called Grey Sparling. I don't know these guys. But Chris, who apparently used to work on the PeopleTools team, wrote a great article on a pre-acquisition, would-be deal between IBM and PeopleSoft that would have standardized PeopleSoft on IBM technology. The behind-the-scenes perspective is interesting. His commentary on the challenges that the company and PeopleSoft customers would have encountered if the deal had gone through was also interesting: ·         "No common ownership. It's hard enough to get large groups of people to work together when they work for the same company, but with two separate companies it is much, much harder. Even within Oracle, progress on Fusion applications was slow until Thomas Kurian took over Fusion applications in addition to Fusion middleware." ·         "No customer buy-in. PeopleSoft customers weren't asking for a conversion to WebSphere, so the fact that doing that could have helped PeopleSoft stay independent wouldn't have meant much to them, especially since the cost of moving to whatever a "PeopleSoft built on WebSphere" would have been significant." ·         "No executive buy-in. This is related to the previous point, but it's worth calling out separately. If Oracle had walked away and the deal with IBM had gone through, and PeopleSoft customers got put through the wringer as part of WebSphere move, all of the PeopleSoft project teams would be put in the awkward position of explaining to their management why these additional costs and headaches were happening. Essentially they would need to "sell" the partnership internally to their own management team. That's not a fun conversation to have." I'm not surprised that something like this was in the works. But I did find the inside scoop and Heller's perspective on the challenges particularly interesting. Especially the advantages of aligning development of applications and infrastructure development under one roof. Here's a link to the whole blog entry.

  • TDD - Red-Light-Green_Light:: A critical view

    - by Renso
    Subject: The concept of red-light-green-light for TDD/BDD style testing has been around since the dawn of time (well almost). Having written thousands of tests using this approach I find myself questioning the validity of the principle The issue: False positive or a valid test strategy that can be trusted? A critical view: I agree that the red-green-light concept has some validity, but who has ever written 2000 tests for a system that goes through a ton of chnages due to the organic nature fo the application and does not have to change, delete or restructure their existing tests? If you asnwer to the latter question is" "Yes I had a situation(s) where I had to refactor my code and it caused me to have to rewrite/change/delete my existing tests", read on, else press CTRL+ALT+Del :-) Once a test has been written, failed the test (red light), and then you comlpete your code and now get the green light for the last test, the test for that functionality is now in green light mode. It can never return to red light again as long as the test exists, even if the test itself is not changed, and only the code it tests is changed to fail the test. Why you ask? because the reason for the initial red-light when you created the test is not guaranteed to have triggered the initial red-light result for the same reasons it is now failing after a code change has been made. Furthermore, when the same test is changed to compile correctly in case of a compile-breaking code change, the green-light once again has been invalidated. Why? Because there is no guarantee that the test code fix is in the same green-light state as it was when it first ran successfully. To make matters worse, if you fix a compile-breaking test without going through the red-light-green-light test process, your test fix is essentially useless and very dangerous as it now provides you with a false-positive at best. Thinking your code has passed all tests and that it works correctly is far worse than not having any tests at all, well at least for that part of the system that the test-code represents. What to do? My recommendation is to delete the tests affected, and re-create them from scratch. I have to agree. Hard to do and justify if it has a significant impact on project deadlines. What do you think?

  • Selectively Exposing Functionallity in .Net

    - by David V. Corbin
    Any developer should be aware of the principles of encapsulation, cross-tier isolation, and cross-functional separation of concerns. However, it seems the few take the time to consider the adage of "minimal yet complete"1 when developing the software. Consider the exposure of "business objects" to the user interface. Some common situations occur: Accessing a given element requires a compound set of calls that do not "make sense" to the User Interface. More information than absolutely required is exposed to the user interface It would be much cleaner if a custom interface was provided that exposed exactly (and only) the information that is required by the consumer. Achieving this using conventional techniques would require the creation (and maintenance!) of custom classes to filter and transpose the information into the ideal format. Determining the ROI on this approach can be very difficult to ascertain, and as a result it is often ignored completely. There is another approach, which is largely made practical by virtual of the Action and Func delegates. From a callers point of view, the following two samples can be used interchangeably:     interface ISomeInterface     {         void SampleMethod1(string param);         string SamepleMethod2(string param);     }       class ISomeInterface     {         public Action<string> SampleMethod1 {get; }         public Func<string,string> SamepleMethod2 {get; }     }   The capabilities this simple changes enable are significant (and remember it does not cange the syntax at the call site): The delegates can be initialized to directly call the proper method of any target class. The delegates can be dynamically updated based on the current state. The "interface" can NOT be cast to the concrete class (which often exposes more functionallity). This patterns By limiting the interface to the exact functionallity required, the reduced surface area will typically result in lower development, testing and maintenance costs. We are currently in the process of posting a project on CodePlex which illustrates this (and many other) techniques which have proven helpful in creating robust yet flexible solutions that are highly efficient2 and maintainable. This post will be updated as soon as the project is published. 1) Credit: Scott  Meyers, Effective C++, Addison-Wesley 1992 2) For those who read my previous post on performance it should be noted that the use of delegates is on the same order of magnitude (actually a tiny amount faster) as conventional interfaces.

  • "Well, Swing took a bit of a beating this week..."

    - by Geertjan
    One unique aspect of the NetBeans community presence at JavaOne 2012 was its usage of large panels to highlight and discuss various aspects (e.g., Java EE, JavaFX, etc) of NetBeans IDE usage and tools. For example, here's a pic of one of the panels, taken by Markus Eisele: Above you see me, Sean Comerford from ESPN.com, Gerrick Bivins from Halliburton, Angelo D'Agnano and Ioannis Kostaras from the NATO Programming Center, and Çagatay Çivici from PrimeFaces. (And Tinu Awopetu was also on the panel but not in the picture!) On one of those panels a remark was made which has kind of stuck with me. Henry Arousell, a member of the "NetBeans Platform Discussion Panel", who works on accounting software in Sweden, together with Thomas Boqvist, who was also at JavaOne, said, a bit despondently, I thought, the following words at the start of the demo of his very professional looking accounting software: "Well, Swing took a bit of a beating this week..." That remark comes in the light of several JavaFX sessions held at JavaOne, together with many sessions from the web and mobile worlds making the argument that the browser, tablet, and mobile platforms are the future of all applications everywhere. However, then I had another look at the list of Duke's Choice Award winners: http://www.oracle.com/us/corporate/press/1854931 OK, there are 10 winners of the Duke's Choice Award this year. Three of them (JDuchess, London Java Community, Student Nokia Developer Group) are not awards for software, but for people or groups. So, that leaves seven awards. Three of them (Hadoop, Jelastic, and Parleys) are, in one way or another, some kind of web-oriented solution, though both Hadoop and Jelastic are broader than that, but are service-oriented solutions, relating to cloud technologies. That leaves four others: NATO air defense software, Liquid Robotics software, AgroSense software, and UNHCR Refugee Registration software. All these are, on the software level, Java desktop solutions that, on the UI layer, make use of Java Swing, together with LuciadMaps (NATO), GeoToolkit (AgroSense), and WorldWind (Liquid Robotics). (And, it went even further than that, i.e., this is not passive usage of Swing but active and motivated: Timon Veenstra, during his AgroSense demo, said "There are far more Swing applications out there than we seem to think. Web developers just make more noise." And, during his Liquid Robotics demo, James Gosling said: "Not everything can be done in HTML.") Seems to me that Java Swing was the enabler of more Duke's Choice Award winners this year than any other UI-oriented Java technology. Now, I'm not going to interpret that one way or another, since I've noticed that interpretations of facts tend to validate some underlying agenda. Take any fact anywhere and you can interpret it to prove whatever opinion you're already holding to be true. Therefore, no interpretation from me. Simply stating the fact that Swing, far from taking a beating during JavaOne 2012, was a more significant user interface enabler of Duke's Choice Award winners than any other Java user interface technology. That's not an interpretation, but a fact.

  • To Serve Man?

    - by Dave Convery
    Since the announcement of Windows 8 and its 'Metro' interface, the .NET community has wondered if the skills they've spent so long developing might be swept aside,in favour of HTML5 and JavaScript. Mercifully, that only seems to be true of SilverLight (as Simon Cooper points out), but it did leave me thinking how easy it is to impose a technology upon people without directly serving their needs. Case in point: QR codes. Once, probably, benign in purpose, they seem to have become a marketer's tool for determining when someone has engaged with an advert in the real world, with the same certainty as is possible online. Nobody really wants to use QR codes - it's far too much hassle. But advertisers want that data - they want to know that someone actually read their billboard / poster / cereal box, and so this flawed technology is suddenly everywhere, providing little to no value to the people who are actually meant to use it. What about 3D cinema? Profits from the film industry have been steadily increasing throughout the period that digital piracy and mass sharing has been possible, yet the industry cinema chains have forced 3D films upon a broadly uninterested audience, as a way of providing more purpose to going to a cinema, rather than watching it at home. Despite advances in digital projection, 3D cinema is scarcely more immersive to us than were William Castle's hoary old tricks of skeletons on wires and buzzing chairs were to our grandparents. iTunes - originally just a piece of software that catalogued and ripped music for you, but which is now multi-purpose bloatware; a massive, system-hogging behemoth. If it was being built for the people that used it, it would have been split into three or more separate pieces of software long ago. But as bloatware, it serves Apple primarily rather than us, stuffed with Music, Video, Various stores and phone / iPad management all bolted into one. Why? It's because, that way, you're more likely to bump into something you want to buy. You can't even buy a new laptop without finding that a significant chunk of your hard drive has been sold to 'select partners' - advertisers, suppliers of virus-busting software, and endless bloatware-flogging pop-ups that make using a new laptop without reformatting the hard drive like stepping back in time. The product you want is not the one you paid for. This is without even looking at services like Facebook and Klout, who provide a notional service with the intention of slurping up as much data about you as possible (in Klout's case, whether you create an account with them or not). What technologies do you find annoying or intrusive, and who benefits from keeping them around?

  • Patterns for Handling Changing Property Sets in C++

    - by Bhargav Bhat
    I have a bunch "Property Sets" (which are simple structs containing POD members). I'd like to modify these property sets (eg: add a new member) at run time so that the definition of the property sets can be externalized and the code itself can be re-used with multiple versions/types of property sets with minimal/no changes. For example, a property set could look like this: struct PropSetA { bool activeFlag; int processingCount; /* snip few other such fields*/ }; But instead of setting its definition in stone at compile time, I'd like to create it dynamically at run time. Something like: class PropSet propSetA; propSetA("activeFlag",true); //overloading the function call operator propSetA("processingCount",0); And the code dependent on the property sets (possibly in some other library) will use the data like so: bool actvFlag = propSet["activeFlag"]; if(actvFlag == true) { //Do Stuff } The current implementation behind all of this is as follows: class PropValue { public: // Variant like class for holding multiple data-types // overloaded Conversion operator. Eg: operator bool() { return (baseType == BOOLEAN) ? this->ToBoolean() : false; } // And a method to create PropValues various base datatypes static FromBool(bool baseValue); }; class PropSet { public: // overloaded[] operator for adding properties void operator()(std::string propName, bool propVal) { propMap.insert(std::make_pair(propName, PropVal::FromBool(propVal))); } protected: // the property map std::map<std::string, PropValue> propMap; }; This problem at hand is similar to this question on SO and the current approach (described above) is based on this answer. But as noted over at SO this is more of a hack than a proper solution. The fundamental issues that I have with this approach are as follows: Extending this for supporting new types will require significant code change. At the bare minimum overloaded operators need to be extended to support the new type. Supporting complex properties (eg: struct containing struct) is tricky. Supporting a reference mechanism (needed for an optimization of not duplicating identical property sets) is tricky. This also applies to supporting pointers and multi-dimensional arrays in general. Are there any known patterns for dealing with this scenario? Essentially, I'm looking for the equivalent of the visitor pattern, but for extending class properties rather than methods. Edit: Modified problem statement for clarity and added some more code from current implementation.
