• Oracle Utilities Application Framework V4.2.0.0.0 Released

  - by ACShorten

  The Oracle Utilities Application Framework V4.2.0.0.0 has been released with Oracle Utilities Customer Care And Billing V2.4. This release includes new functionality and updates to existing functionality and will be progressively released across the Oracle Utilities applications. The release is quite substantial with lots of new and exciting changes. The release notes shipped with the product includes a summary of the changes implemented in V4.2.0.0.0. They include the following: Configuration Migration Assistant (CMA) - A new data management capability to allow you to export and import Configuration Data from one environment to another with support for Approval/Rejection of individual changes. Database Connection Tagging - Additional tags have been added to the database connection to allow database administrators, Oracle Enterprise Manager and other Oracle technology the ability to monitor and use individual database connection information. Native Support for Oracle WebLogic - In the past the Oracle Utilities Application Framework used Oracle WebLogic in embedded mode, and now, to support advanced configuration and the ExaLogic platform, we are adding Native Support for Oracle WebLogic as configuration option. Native Web Services Support - In the past the Oracle Utilities Application Framework supplied a servlet to handle Web Services calls and now we offer an alternative to use the native Web Services capability of Oracle WebLogic. This allows for enhanced clustering, a greater level of Web Service standards support, enchanced security options and the ability to use the Web Services management capabilities in Oracle WebLogic to implement higher levels of management including defining additional security rules to control access to individual Web Services. XML Data Type Support - Oracle Utilities Application Framework now allows implementors to define XML Data types used in Oracle in the definition of custom objects to take advantage of XQuery and other XML features. Fuzzy Operator Support - Oracle Utilities Application Framework supports the use of the fuzzy operator in conjunction with Oracle Text to take advantage of the fuzzy searching capabilities within the database. Global Batch View - A new JMX based API has been implemented to allow JSR120 compliant consoles the ability to view batch execution across all threadpools in the Coherence based Named Cache Cluster. Portal Personalization - It is now possible to store the runtime customizations of query zones such as preferred sorting, field order and filters to reuse as personal preferences each time that zone is used. These are just the major changes and there are quite a few more that have been delivered (and more to come in the service packs!!). Over the next few weeks we will be publishing new whitepapers and new entries in this blog outlining new facilities that you want to take advantage of.

• RealTek RTL8188CE WiFi adapter doesn't connect reliably

  - by ken.ganong

  I recently bought a new system76 laptop which came pre-installed with Ubuntu 11.10. I've been having trouble with my wireless connectivity. It seems that my connection with my wireless network keeps going in and out. It is not my network--I have seen the same problem on multiple WiFi networks and at different distances and reported link qualities.

• Justification for learning/implementing newer Microsoft technologies

  - by Darren

  I work at a large healthcare organization as a mid-level software developer. I have over 10 years experience in the IT industry using Microsoft technologies (ASP.NET & SQL Server). When I go to conferences, code camps, .net user group meetings, I hear of all kinds of new tools and technologies: MVC, LINQ, Entity Framework, WCF Web Services, etc. I guess you could say I'm in my comfort zone using the same old stuff from asp.net 2.0. I use typed datasets for my data access layer. I use web forms and feature rich server controls with master pages. I know how to use plain old SQL and create queries in my typed datasets to get at data my applications need. Throughout my career, I'm always sensitive to not become obsolete with my skill set. What I currently use works fine and my development time is fast. But I'm concerned that if I were to be laid off, I would be asked in interviews how many MVC apps I've written. Or how I am with LINQ or WCF web services. I know that it doesn't matter how many conferences, books, or videos I watch on some new technology...I have to implement/use it or it simply won't sink in. Also, managers who interview don't care how much someone reads up on something, only real use and experience with a technology. I have a new project to write. I've gone to my manager and have asked for additional time for the project for learning/implementing technology I may not be familiar with. Our organization encourages its employees to "learn and grow" and to continue are education. But I always get resistance when I ask for more time to ramp up on something new to implement. My manager is asking for concrete business reasons for implementing these new technologies. I don't have business reasons. My reasons are because I don't want to become obsolete. I could say it would make the project more maintainable in the future by other developers since at some point people could stop using these older technologies, but that' about all I can think of. Does Linq/Entity Framework/MCV apps perform better? So much so that the customers (users in departments I'm creating this app for) need? I doubt it. I'm interested in you guy's thoughts on this. Do many of you have similar plights with trying to use newer upcoming technologies? I doubt I'm on the bleeding edge of technology, either. Are there "business reasons" that you would bring to light for using these technologies? Thanks in advance! Sorry for the long wall of text.

• Visual Studio 2010 Best Practices

  - by Etienne Tremblay

  I’d like to thank Packt for providing me with a review version of Visual Studio 2010 Best Practices eBook. In fairness I also know the author Peter having seen him speak at DevTeach on many occasions.  I started by looking at the table of content to see what this book was about, knowing that “best practices” is a real misnomer I wanted to see what they were.  I really like the fact that he starts the book by really saying they are not really best practices but actually recommend practices.  As a Team Foundation Server user I found that chapter 2 was more for the open source crowd and I really skimmed it.  The portion on Branching was well documented, although I’m not a fan of the testing branch myself, but the rest was right on. The section on merge remote changes (bring the outside to you) paradigm is really important and was touched on. Chapter 3 has good solid practices on low level constructs like generics and exceptions. Chapter 4 dives into architectural practices like decoupling, distributed architecture and data based architecture.  DTOs and ORMs are touched on briefly as is NoSQL. Chapter 5 is about deployment and is really a great primer on all the “packaging” technologies like Visual Studio Setup and Deployment (depreciated in 2012), Click Once and WIX the major player outside of commercial solutions.  This is a nice section on how to move from VSSD to WIX this is going to be important in the coming years due to the fact that VS 2012 doesn’t support VSSD. In chapter 6 we dive into automated testing practices, including test coverage, mocking, TDD, SpecDD and Continuous Testing.  Peter covers all those concepts really nicely albeit succinctly. Being a book on recommended practices I find this is really good. I really enjoyed chapter 7 that gave me a lot of great tips to enhance my Visual Studio “experience”.  Tips on organizing projects where good.  Also even though I knew about configurations I like that he put that in there so you can move all your settings to another machine, a lot of people don’t know about that. Quick find and Resharper are also briefly covered.  He touches on macros (depreciated in 2012).  Finally he touches on Continuous Integration a very important concept in today’s ALM landscape. Chapter 8 is all about Parallelization, threads, Async, division of labor, reactive extensions.  All those concepts are touched on and again generalized approaches to those modern problems are giving.       Chapter 9 goes into distributed apps, the most used and accepted practice in the industry for .NET projects the chapter tackles concepts like Scalability, Messaging and Cloud (the flavor of the month of distributed apps, although I think this will stick ;-)).  He also looks a protocols TCP/UDP and how to debug distributed apps.  He touches on logging and health monitoring. Chapter 10 tackles recommended practices for web services starting with implementing WCF services, which goes into all sort of goodness like how to host in IIS or self-host.  How to manual test WCF services, also a section on authentication and authorization.  ASP.NET Web services are also touched on in that chapter All in all a good read, nice tips and accepted practices.  I like the conciseness of the subjects and Peter touches on a lot of things in this book and uses a lot of the current technologies flavors to explain the concepts.   Cheers, ET

• OpenWorld Day 1

  - by Antony Reynolds

  A Day in the Life of an OpenWorld Attendee Part I Lots of people are blogging insightfully about OpenWorld so I thought I would provide some non-insightful remarks to buck the trend! With 50,000 attendees I didn’t expect to bump into too many people I knew, boy was I wrong!  I walked into the registration area and immediately was hailed by a couple of customers I had worked with a few months ago.  Moving to the employee registration area in a different hall I bumped into a colleague from the UK who was also registering.  As soon as I got my badge I bumped into a friend from Ireland!  So maybe OpenWorld isn’t so big after all! First port of call was Larrys Keynote.  As always Larry was provocative and thought provoking.  His key points were announcing the Oracle cloud offering in IaaS, PaaS and SaaS, pointing out that Fusion Apps are cloud enabled and finally announcing the 12c Database, making a big play of its new multi-tenancy features.  His contention was that multi-tenancy will simplify cloud development and provide better security by providing DB level isolation for applications and customers. Next day, Monday, was my first full day at OpenWorld.  The first session I attended was on monitoring of OSB, very interesting presentation on the benefits achieved by an Illinois area telco – US Cellular.  Great discussion of why they bought the SOA Management Packs and the benefits they are already seeing from their investment in terms of improved provisioning and time to market, as well as better performance insight and assistance with capacity planning. Craig Blitz provided a nice walkthrough of where Coherence has been and where it is going. Last night I attended the BOF on Managed File Transfer where Dave Berry replayed Oracles thoughts on providing dedicated Managed File Transfer as part of the 12c SOA release.  Dave laid out the perceived requirements and solicited feedback from the audience on what if anything was missing.  He also demoed an early version of the functionality that would simplify setting up MFT in SOA Suite and make tracking activity much easier. So much for Day 1.  I also ran into scores of old friends and colleagues and had a pleasant dinner with my friend from Ireland where I caught up on the latest news from Oracle UK.  Not bad for Day 1!

• 13 Things From the Oracle Social Summit You Should Know

  - by Mike Stiles

  Oracle held its first annual Oracle Social Summit, “The School for the Socially Gifted,” this past week in Las Vegas.  If anyone came to the event uncertain as to why Oracle has such an interest in social, and what its plans for social are, they left with an entirely new vision of where social is headed, and why.For those unable to attend, I was able to keep my MacBook charged just long enough to capture some of the more pertinent takeaways.1. The social enterprise is inevitable.  Social technology is disrupting the hierarchies of big companies.  It’s a revolution in corporate structures, just as it has been in various governments.  It’s not crazy to ask yourself if your CEO is the next Mubarak.  (David Kilpatrick Author of “The Facebook Effect” and founder of the Techonomy Conference) 2. The social enterprise represents collaboration on steroids.  It’s tapping into the power of your people, as opposed to keeping them “in their place.”  3. 1 in every 7 humans on earth is an active Facebook user.  75% have posted a negative comment after a poor customer experience.  The average user will inform 53 people of a bad experience.4. Checking social media is the 2nd biggest use of phones now.  Reading posts from brands is 4th.5. 70% of marketers have little or no understanding of the social conversations happening around their brand.6. Advertising, when done well, is content we care about, preferably informed by those we trust.7. Acquiring low-quality fans through gimmicks, or focusing purely on fan acquisition is a mistake.  And relying purely on organic distribution is a mistake.  (John Yi, Head of Marketing Partnerships – Facebook)8. Using all this newfound data and insight serves to positively affect the customer experience.  It allows organizations to now leverage the investments they’ve made in social up to now.9. Social is not a marketing utopia where everything is free.  It’s pay to play.  The paid component is about driving attention.  10. We are only in the infancy of ad-targeting opportunities in social.  There’s an evolution underway from interest-based targeting to action-based targeting.11. There’s actually very little overlap of the people following you on different social platforms.  Don’t assume it’s the same audience on each.12. People who can create content and who also have an understanding of what drives that content are growing increasingly valuable.13. Oracle Social’s future is enterprise SRM, integrated across marketing, selling, service, HR and every other corner of the organization.And in case you thought those were the only gems to come out of the summit, you may want to keep an eye out for Tuesday’s Social Spotlight, ever so aptly titled “13 More Things from the Oracle Social Summit You Should Know.”

• PayPal India Problems Continues

  - by Ravish

  Reserve Bank of India has been giving hard time to PayPal and its users in India. RBI had previously blocked PayPal transactions in India a few times, and they made it difficult to withdraw payments by enforcing exports and forex related compliance. Here is yet another bad news for Indian PayPal users. With effect from March 1st, Indian users cannot receive payments of more than $500 in your PayPal account. Moreover, you cannot keep or use any funds in your PayPal account. You can use your PayPal balance to make send money for any goods or services, and must withdraw it to your bank account within 7 days of the receipt. These changes have rendered PayPal almost useless for small business, webmasters and publishers. Most webmasters and publishers rely on PayPal to receive payments from advertisers and clients. It has also made it impossible to buy anything online with PayPal. Sending payments abroad via other channels is already a pain, sending a bank wire requires too many formalities, documentation and time. Moreover, you are even required to deduct TDS on payments you make for any products or services. The restrictions will take effect on March 1st, so you have 30 days to complete any pending transactions you may have. This step by RBI is yet another gimmick by corrupt Indian Government to make life difficult of entrepreneurs, kill innovation, slap more taxes and create more channels to take bribes. Following is the notification from PayPal about this issue: As part of our commitment to provide a high level of customer service, we would like to give you a 30-day advance notice on changes to our user agreement for India. With effect from 1 March 2011, you are required to comply with the requirements set out in the notification of the Reserve Bank of India governing the processing and settlement of export-related receipts facilitated by online payment gateways (“RBI Guidelines”). In order to comply with the RBI Guidelines, our user agreement in India will be amended for the following services as follows: Any balance in and all future payments into your PayPal account may not be used to buy goods or services and must be transferred to your bank account in India within 7 days from the receipt of confirmation from the buyer in respect of the goods or services; and Export-related payments for goods and services into your PayPal account may not exceed US$500 per transaction. We seek your understanding as we continue to employ our best efforts to comply with the RBI Guidelines in a timely manner.

• Social Analytics and the Customer

  - by David Dorf

  Many successful retailers put the customer at the center of everything they do, so its important that the customer is modeled correctly across all their systems.  The path to omni-channel starts and ends with the customer so at ARTS, our next big project is focused on ensuring a consistent representation of customers across our transactional data model, datawarehouse model, and XML schemas.  Further, we've started a new whitepaper that describes how Big Data and Social Media Analytics should be leveraged by retailers to add and additional level of customer insight. Let's start by taking a closer look at the meaning of social analytics.  Here's my definition: Social Analytics, in the retail context, describes the analysis of data obtained from social media sources in an effort to better comprehend and interact with the community of consumers.  This discipline seeks to understand what’s being said by the community about brands and products (“monitoring”), as well as understand the behaviors of those in the community (“profiling”).  The results are used to enforce the brand image, improve product decisions, and better focus marketing, all of which lead to increased sales. To help illustrate the facets of social analytics, I drew the diagram below which was originally published by Retail Touchpoints. There are lots of tools on the market that allow retailers to monitor social media for brand and product mentions.  These include analysis of sentiment, reach, share of voice, engagement, etc.  When your brand is mentioned, good or bad, its an opportunity to engage with the customer and possibly lead to a sale.  Because products are not always unique, its much more difficult to monitor product mentions, but detecting product trends early can help a retailer make better merchandising decisions, especially in fashion. Once a retailer understands what's being said, the next step is learn more about who's saying it.  That involves profiling customers beyond simple demographics to understand their motivations.  Much can be learned from patterns, and even more when customers voluntarily share their data.  Knowing that a customer is passionate about, for example, mountain biking allows the retailer to make relevant offers on helmets, ask for opinions on hydration, and help spread marketing messages. Social analytics has many facets that benefit retailers, some of which are easy but many of which are hard.  Its important for the CMO and CIO to work closely together to plan for these capabilities and monitor the maturity of tools on the market.  This is an area that will separate winners from losers.

• Did I lost my RAID again?

  - by BarsMonster

  Hi! A little history: 2 years ago I was really excited to find out that mdadm is so powerful so it even can reshape arrays so you can start with a smaller array and the grow it as you need. I've bought 3x1Tb drives and made RAID-5. It was fine for a year. Then I bought 2x more, and tried to reshape to RAID-6 out of 5 drives, and due to some mess with superblock versions, lost all content. Had to rebuild it from scratch, but 2Tb of data were gone. Yesterday I bought 2 more drives, and this time I had everything: properly built array, UPS. I've disabled write intent map, added 2 new drives as a spare and run a command to grow array to 7-disk. It started working, but speed was ridiculously slow, ~100kb/sec. AFter processing first 37Mb at such an amasing speed, one of old HDDs fails. I properly shutdown PC and disconnected failed drive. After bootup it appeared it recreated intent map as it was still in mdadm config, so I removed it from config and rebooted again. Now all I see is that all mdadm processes deadlocks, and don't do anything. PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 1937 root 20 0 12992 608 444 D 0 0.1 0:00.00 mdadm 2283 root 20 0 12992 852 704 D 0 0.1 0:00.01 mdadm 2287 root 20 0 0 0 0 D 0 0.0 0:00.01 md0_reshape 2288 root 18 -2 12992 820 676 D 0 0.1 0:00.01 mdadm And all I see in mdstat is: $ cat /proc/mdstat Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4] [raid10] md0 : active raid6 sdb1[1] sdg1[4] sdf1[7] sde1[6] sdd1[0] sdc1[5] 2929683456 blocks super 1.2 level 6, 1024k chunk, algorithm 2 [7/6] [UU_UUUU] [>....................] reshape = 0.0% (37888/976561152) finish=567604147.2min speed=0K/sec I've already tried mdadm 2.6.7, 3.1.4 and 3.2 - nothing helps. Did I lost my data again? Any suggestions how can I make it work? OS is Ubuntu Server 10.04.2... PS. Needless to say that data is unaccessible - I cannot mount /dev/md0 as save the most valuable data. You can see my disappointment - the very specific thing I was excited about failed twice taking 5Tb of my data with it.

• Creative, busy Devoxx week

  - by JavaCecilia

  I got back from my first visit to the developer conference Devoxx in Antwerp. I can't describe the vibes of the conference, it was a developer amusement park, hackergartens, fact sessions, comic relief provided by Java Posse, James Bond and endless hallway discussions.All and all - I had a lot of fun, my main mission was to talk about Oracle's main focus for OpenJDK which besides development and bug fixing is making sure the infrastructure is working out for the full community. My focus was not to hang out at night club the Noxx, but that was came included in the package :)The London Java community leaders Ben Evans and Martijn Verburg are leading discussions in the community to lay out the necessary requirements for the infrastructure for build and test in the open. They called a first meeting at JavaOne gathering 25 people, including people from RedHat, IBM and Oracle. The second meeting at Devoxx included 14 participants and had representatives from Oracle and IBM. I hope we really can find a way to collaborate on this, making sure we deliver an efficient infrastructure for all engineers to contribute to OpenJDK with.My home in all of this was the BOF rooms and the sessions there meeting the JUG leaders, talking about OpenJDK infrastructure and celebrating the Duchess Duke Award together with the others. The restaurants in the area was slower than I've ever seen, so I missed out on Trisha Gee's brilliant replay of the workshop "The Problem with Women in IT - an Agile Approach" where she masterly leads the audience (a packed room, 50-50 gender distribution) to solve the problem of including more diversity in the developer community. A tough and sometimes sensitive topic where she manages to keep the discussion objective with a focus of improving the matter from a business perspective. Mattias Karlsson is organizing the Java developer conference Jfokus in Stockholm and was there talking to Andres Almires planning a Hackergarten with a possible inclusion of an OpenJDK bugathon. That would be really cool, especially as the Oracle Stockholm Java development office is just across the water from the Jfokus venue, some of the local JVM engineers will likely attend and assist, even though the bug smashing theme will likely be more starter level build warnings in Swing or langtools than fixing JVM bugs.I was really happy that I managed to catch a seat for the Java Posse live podcast "the Third Presidential Debate" a lot of nerd humor, a lot of beer, a lot of fun :) The new member Chet had a perfect dead pan delivery and now I just have to listen more to the podcasts! Can't get the most perfect joke out of my head, talking about beer "As my father always said: Better a bottle in front of me than a frontal lobotomy" - hilarious :)I attended the sessions delivered by my Stockholm office colleagues Marcus Lagergren (on dynamic languages on the jvm, JavaScript in particular) and Joel Borggrén-Franck (Annotations) and was happy to see the packed room and all the questions raised at the end.There's loads of stuff to write about the event, but just have to pace myself for now. It was a fantastic event, captain Stephan Janssen with crew should be really proud to provide this forum to the developer community!

• How to get bearable 2D and 3D performance on AMD Radeon HD 6950?

  - by l0b0

  I have had an AMD Radeon HD 6950 (i.e., Cayman series) for a couple years now, and I have tried a lot of combinations of drivers and settings with terrible results. I'm completely at a loss as to how to proceed. The open source driver has much better 2D performance, but it offloads all OpenGL rendering to the CPU. What I've tried so far: All the latest stable Ubuntu releases in the period, plus one Linux Mint release. All the latest stable AMD Catalyst Proprietary Display Drivers, and currently 13.1. The unofficial wiki installation instructions for every Ubuntu version and the semi-official Ubuntu instructions. All the tips and tweaks I could find for Minecraft (Optifine, reducing settings to minimum), VLC (postprocessing at minimum, rendering at native video size), Catalyst Control Center (flipped every lever in there) and X11 (some binary toggles I can no longer remember). Results: Typically 13-15 FPS in Minecraft, 30 max (100+ in Windows with the same driver version). Around 10 FPS in Team Fortress 2 using the official Steam client. Choppy video playback, in Flash and with VLC. CPU use goes through the roof when rendering video (150% for 1080p on YouTube in Chromium, 100% for 1080p H264 in VLC). glxgears shows 12.5 FPS when maximized. fgl_glxgears shows 10 FPS when maximized. Hardware details from lshw: Motherboard ASUS P6X58D-E CPU Intel Core i7 CPU 950 @ 3.07GHz (never overclocked; 64 bit) 6 GB RAM Video card product "Cayman PRO [Radeon HD 6950]", vendor "Hynix Semiconductor (Hyundai Electronics)" 2 x 1920x1200 monitors, both connected with HDMI. I feel I must be missing something absolutely fundamental here. Is there no accelerated support for anything on 64-bit architectures? Does a dual monitor completely mess up the driver? $ fglrxinfo display: :0 screen: 0 OpenGL vendor string: Advanced Micro Devices, Inc. OpenGL renderer string: AMD Radeon HD 6900 Series OpenGL version string: 4.2.11995 Compatibility Profile Context $ glxinfo | grep 'direct rendering' direct rendering: Yes I am currently using the open source driver, with the following results: Full frame rate and low CPU load when playing 1080p video. Black screen (but music in the background) in Team Fortress 2. Similar performance in Minecraft as the Catalyst driver. In hindsight obvious, since both end up offloading the rendering to the CPU. My /var/log/Xorg.0.log after upgrading to AMD Catalyst 13.1. Some possibly important lines: (WW) Falling back to old probe method for fglrx (WW) fglrx: No matching Device section for instance (BusID PCI:0@3:0:1) found The generated xorg.conf. The disabled "monitor" 0-DFP9 is actually an A/V receiver, which sometimes confuses the monitor drivers when turned on/off (but not in Windows). All three "monitor" devices are connected with HDMI. Edit: Chris Carter's suggestion to use the xorg-edgers PPA (Catalyst 13.1) resulted in some improvement, but still pretty bad performance overall: Minecraft stabilizes at 13-17 FPS, but at least the CPU load is "only" at 45-60%. Still 150% CPU use for 1080p video rendering on YouTube in Chromium. Massive improvement for 1080p H264 in VLC: 40-50% CPU use and no visible jitter glxgears performance about doubled to 25-30 FPS when maximized. fgl_glxgears still at ~10 FPS when maximized.

• Dropped impression 25 days after restructure

  - by Hamid

  Our website is a non English property related website (moshaver.com) which is similar to rightmove.co.uk. On September 2012 our website was adversely affected by Panda causing our Google incoming clicks to drop from around 3000 clicks to less than a thousand. We were hoping that Google will eventually realize that we are not a spam website and things will get better. However, in August 2013 we were almost sure that we needed to do something, so we started to restructure our web content. We used the canonical tag to remove our search results and point to our listing pages, using the noindex tag to remove it from our listing pages which does not have any properties at the moment. We also changed title tags to more friendly ones, in addition to other changes. Our changes were effective on 10th August. As shown in the graph taken from Google Analytics Search Engine Optimization section, these changes has resulted in an increase in the number of times Google displayed our results in its search results. Our impressions almost doubled starting 15th August. However, as the graph shows, our CTR dropped from this date from around 15% to 8%. This might have been because of our changed title tags (so people were less likely to click on them), or it might be normal for increased impressions. This situation has continued up until 10th September, when our impressions decreased dramatically to less than a thousand. This is almost 30% of our original impressions (before website restructure) and 15% of the new impressions. At the same time our impressions has increased dramatically to around 50%. I have two theories for this increase. The first one is that these statistics are less accurate for lower impressions. The second one is that Google is now only displaying our results for queries directly related to our website (our name, our url), and not for general terms, such as "apartments in a specific city". The second theory also explains the dramatic decrease in impression as well. After digging the analytic data a little more, I constructed the following table. It displays the breakdown of our impressions, clicks and ctr in different Google products (web and image) and in total. What I understand from this table is that, most of our increased impressions after restructure were on the image search section. I don't think users of search would be looking for content in our website. Furthermore, it shows that the drop in our web search ctr, is as dramatic of the overall ctr (-30% in compare to -60%) . I thought posting it here might help you understand the situation better. Is it possible that Google has tested our new structure for 25 days, and then decided to decrease our impressions because of the the new low CTR? Or should we look for another factor? If this is the case, how long does it usually take for Google to give us another chance? It has been one month since our impressions has dropped.

• Unit testing in Django

  - by acjohnson55

  I'm really struggling to write effective unit tests for a large Django project. I have reasonably good test coverage, but I've come to realize that the tests I've been writing are definitely integration/acceptance tests, not unit tests at all, and I have critical portions of my application that are not being tested effectively. I want to fix this ASAP. Here's my problem. My schema is deeply relational, and heavily time-oriented, giving my model object high internal coupling and lots of state. Many of my model methods query based on time intervals, and I've got a lot of auto_now_add going on in timestamped fields. So take a method that looks like this for example: def summary(self, startTime=None, endTime=None): # ... logic to assign a proper start and end time # if none was provided, probably using datetime.now() objects = self.related_model_set.manager_method.filter(...) return sum(object.key_method(startTime, endTime) for object in objects) How does one approach testing something like this? Here's where I am so far. It occurs to me that the unit testing objective should be given some mocked behavior by key_method on its arguments, is summary correctly filtering/aggregating to produce a correct result? Mocking datetime.now() is straightforward enough, but how can I mock out the rest of the behavior? I could use fixtures, but I've heard pros and cons of using fixtures for building my data (poor maintainability being a con that hits home for me). I could also setup my data through the ORM, but that can be limiting, because then I have to create related objects as well. And the ORM doesn't let you mess with auto_now_add fields manually. Mocking the ORM is another option, but not only is it tricky to mock deeply nested ORM methods, but the logic in the ORM code gets mocked out of the test, and mocking seems to make the test really dependent on the internals and dependencies of the function-under-test. The toughest nuts to crack seem to be the functions like this, that sit on a few layers of models and lower-level functions and are very dependent on the time, even though these functions may not be super complicated. My overall problem is that no matter how I seem to slice it, my tests are looking way more complex than the functions they are testing.

• Get the Picture: Pinterest for Marketers

  - by Mike Stiles

  When trying to determine on which networks to conduct social marketing, the usual suspects immediately rise to the top; Facebook & Twitter, then LinkedIn (especially if you’re B2B), then maybe some Google Plus to hedge SEO bets.  So at what juncture do brands get excited about Pinterest? Pinterest has been easy for marketers to de-prioritize thanks to the perception its usage is so dominated by women. Um, what’s wrong with that? Women make an estimated 85% of all consumer purchases. So if there are indeed over 30 million US women active on it monthly, and they do 92% of the pinning, and 84% are still active on it after 4 years, when did an audience of highly engaged, very likely sales conversions become low priority? Okay, if you’re a tech B2B SaaS product like the Oracle Social Cloud, Pinterest may not be where you focus. But if you operate in the top Pinterest categories, which are truly far-reaching, it’s time to take note of Pinterest’s performance to date: 40.1 million monthly users in the US (eMarketer). Over 30 billion pins, half of which were pinned in the last 6 months. (Big momentum) 75% of usage is on their mobile app. (In solid shape for the mobile migration) Pinterest sharing grew 58% in 2013, beating Facebook, Twitter, or LinkedIn. (ShareThis) Pinterest is the 3rd most popular sharing platform overall (over email), with 48% of all sharing on tablets. Users referred by Pinterest are 10% more likely to buy on e-commerce sites and tend to spend twice that of users coming from Facebook. (Shopify) To be fair, brands haven’t had any paid marketing opportunities on that platform…until recently. Users are seeing Promoted Pins in both category and search feeds from rollout brands like Gap, ABC Family, Ziploc, and Nestle. Are the paid pins annoying users? It seems more so than other social networks, they’re fitting right in to the intended user experience and being accepted, getting almost as many click-throughs as user pins. New York Magazine’s Kevin Roose laid it out succinctly; Pinterest offers a place that’s image-centric, search-friendly, makes things easy to purchase, makes things easy to share, and puts users in an aspirational mood to buy. Pinterest is very confident in the value of that combo and that audience, with CPM rates 5x that of the most expensive Facebook ad, plus (at least for now) required spending commitments and required pin review by Pinterest for quality. The latest developments; a continued move toward search and discovery with enhancements like Guided Search to help you hone in on what interests you, Custom Categories, and the rumored Visual Search that stands to be a liberation from text. And most recently, Pinterest has opened up its API so brands can get access to deeper insights into the best search terms and categories in which to play ball, as well as what kinds of pins stand to perform best in those areas. As we learned in our rundown this week of Social Media Examiner’s Social Media Marketing Industry Report, around 50% of marketers specifically intend on upping their use of Pinterest. If you’re a big believer in fishing where the fish are, that’s probably an efficient position to take. @mikestiles @oraclesocialPhoto: Adam Lambert_Gorwyn, freeimages.com

• Is Java viable for serious game development?

  - by tehtros

  Ever since I was a little kid, my dream has been to develop games. Well, now that I am older, more mature, and have some programming experience, I would like to start. However, I would like to turn this into a career. The problem, is that my language of choice is Java. Now, I am not intending this to be a Java vs. C++ question, but rather, is Java an acceptable language for serious game development, instead of lower level languages like C++. By serious, I mean high quality graphics, and being able to play a game with said high quality graphics, without much lag on decent computers. Also, eventually, possible making it to consoles. I have scoured the internet, but there are not very many resources for Java game development, not nearly as many as C++. In fact, most engines are written in C++. Once, I tried to play a made with jMonkeyEngine. The game was terribly slow, to the point where my computer froze. I had no other Java applications running and nothing too resource intensive. Keep in mind, that my computer can play most modern 3D games with ease. So, I am really serious about game development, is Java still a viable choice? I have tried multiple times to learn C++, but I don't really like the language. I don't really know why, but usually, whenever I try to learn, I can never grasp the topics. Also, my most of my friends know Java, and one is even anti-C++, saying that no one knows how to use it right. Then, he goes to say that "there is no right way to use C++, that it can not be used correctly. The nature of the language prevents good code." Also, if I continue to learn and improve Java now, and it turns out that later I am required to learn C++, will making the switch be difficult? So, in short, can Java be taken serious, for serious game development. This includes heavy graphics, fast game play without lag, and possibly, and easy switch to consoles?

• Why no more macro languages?

  - by Muhammad Alkarouri

  In this answer to a previous question of mine about scripting languages suitability as shells, DigitalRoss identifies the difference between the macro languages and the "parsed typed" languages in terms of string treatment as the main reason that scripting languages are not suitable for shell purposes. Macro languages include nroff and m4 for example. What are the design decisions (or compromises) needed to create a macro programming language? And why are most of the mainstream languages parsed rather than macro? This very similar question (and the accepted answer) covers fairly well why the parsed typed languages, take C for example, suffer from the use of macros. I believe my question here covers different grounds: Macro languages or those working on a textual level are not wholly failures. Arguably, they include bash, Tcl and other shell languages. And they work in a specific niche such as shells as explained in my links above. Even m4 had a fairly long time of success, and some of the web template languages can be regarded as macro languages. It is quite possible that macros and parsed typing do not go well together and that is why macros "break" common languages. In the answer to the linked question, a macro like #define TWO 1+1 would have been covered by the common rules of the language rather than conflicting with those of the host language. And issues like "macros are not typed" and "code doesn't compile" are not relevant in the context of a language designed as untyped and interpreted with little concern for efficiency. The question about the design decisions needed to create a macro language pertain to a hobby project which I am currently working on on designing a new shell. Taking the previous question in context would clarify the difference between adding macros to a parsed language and my objective. I hope the clarification shows that the question linked doesn't cover this question, which is two parts: If I want to create a macro language (for a shell or a web template, for example), what limitations and compromises (and guidelines, if exist) need to be done? (Probably answerable by a link or reference) Why have no macro languages succeed in becoming mainstream except in particular niches? What makes typed languages successful in large programming, while "stringly-typed" languages succeed in shells and one-liner like environments?

• Oracle is #1 in Life Sciences!

  - by Michael Snow

  Guest post today by: John Klinke, Senior Principal Product Manager, Oracle WebCenter Content 12.00 Normal 0 false false false EN-US X-NONE X-NONE /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin-top:0in; mso-para-margin-right:0in; mso-para-margin-bottom:10.0pt; mso-para-margin-left:0in; line-height:115%; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Calibri","sans-serif"; mso-fareast-font-family:Calibri; mso-bidi-font-family:"Times New Roman";} Based on the announcement last week at EMC World about Documentum for Life Sciences, it looks like EMC is starting to have regrets about pulling out of the life sciences space over the last few years. Certainly their content management customers and partners in life sciences have noticed their retreat. Many of them are now talking to us about WebCenter Content since they’ve seen the writing on the wall regarding Documentum’s decline, including falling revenue, shrinking investment, departure of key executives, and EMC’s auditing of existing customers. While EMC has been neglecting the life sciences industry over the last few years, Oracle has been increasing its investment and commitment by providing best-of-breed solutions to enable pharmaceutical, medical device, biotech and CRO companies to improve productivity and drive innovation. As a result, according to IDC Health Insights, Oracle is #1 in life sciences. From research and development through clinical development and manufacturing to sales and marketing, Oracle provides the solutions that life sciences companies depend on to accelerate R&D, expedite clinical trials, and speed time to market. Specifically for Oracle WebCenter, our life sciences business is booming thanks to our comprehensive offerings led by Oracle WebCenter Content, our 21 CFR Part 11 compliant enterprise content management platform. Unlike Documentum, WebCenter Content is all about keeping the cost of ownership low - through simplicity, flexibility, and out-of-the-box integrations. WebCenter Content is a single, comprehensive ECM platform that can handle all your content management needs, from controlled documents to digital asset management, records management and document imaging and capture. And it is much more flexible, letting you do configuration changes instead of customizations to meet your business needs. It also saves you money by being pre-integrated with the rest of the Oracle Fusion Middleware technology stack and with leading enterprise applications like Siebel (including Siebel CTMS), Primavera, E-Business Suite, JD Edwards and PeopleSoft. So if you think EMC’s announcement last week was too little and too late, I’m happy to report that Oracle is here to help. Back in October, we announced our Move Off Documentum offer, which provides a 100% trade-in credit for your Documentum licenses when you purchase Oracle WebCenter, and the good news is, this offer is still available for a limited time. So stop maintaining Documentum and start innovating with Oracle WebCenter. For more details see www.oracle.com/moveoff/documentum.

• Nest reinvents smoke detectors. Introduces smart and talking smoke detector that keeps quite when you wave

  - by Gopinath

  Nest, the leading smart thermostat maker has introduced a smart home device today- Nest Protect, a smart, talking smoke & carbon monoxide detector that can quite when you wave your hand. Less annoyances and more intelligence Smoke detectors are around for hundreds of years and playing a major role in providing safety from fire accidents at home. But the technology of these devices is stale and there is no major innovation for the past several years. With the introduction of Nest Protect, the landscape of smoke detectors is all set to change just like how Nest thermostat redefined the industry two years ago. Nest Protect is internet enabled and equipped with motion- and smoke-detection sensors so that when it starts beeping you can silence it by waving hand instead of doing circus feats to turn off the alarm. Everyone who cooks in a home equipped with smoke detector would know how annoying it is to turn off sensitive smoke detectors that goes off control quite often. Apart from addressing the annoyances of regular smoke detector, Nest Protect has talking capabilities. It can alert users with clear & actionable instructions when it detects a danger. Instead of harsh beeps it actually speak to you so you know what is happening. It will tell you what smoke it has detected and in which room it is detected. Multiple Nest Protects installed in a home can communicate with each other. Lets say that there is a smoke in bed room, the Nest Protect installed in bed room shares this information to all Nest Protects installed in the home and your kitchen device can alert you that there is a smoke in bed room. There is an App for that The internet enabled Nest Protect has an app to view its status and various alerts. When the Protect is running on low battery it alerts you to replace them soon. If there is a smoke at home and you are away, you will get message alerts. The app works on all major smartphones as well as tablets. Auto shuts down gas furnaces/heaters on smoke Apart from forming a network with other Nest Protect devices installed at home, they can also communicate with Nest Thermostat if it is installed. When carbon monoxide is detected it can shut off your gas furnace automatically. Also with the help of motion detectors it improves Nest Thermostat’s auto-away functionality. It looks elegant and costs a lot more than a regular smoke detector Just like Nest Thermostat, Nest Protect is elegant and adorable. You just fall in love with it the moment you see it. It’s another master piece from the designer of Apple’s iPod. All is good with the Nest Protect, except the price!! It costs whooping $129, which is almost 4 times more expensive than the best selling conventional thermostats available at $30. A single bed room apartment would require at least 3 detectors and it costs around $390 to install Nest Protects compared to 90$ required for conventional smoke detectors. Though Nest Thermostat is an expensive one compared to conventional thermostats, it offered great savings through its intelligent auto-away feature. Users were able to able to see returns on their investments. If Nest Protect also can provide good return on investment the it will be very successful.

• TechEd 2010 Day Three: The Database Designer (Isn't)

  - by BuckWoody

  Yesterday at TechEd 2010 here in New Orleans I worked the front-booth, answering general SQL Server questions for the masses. I was actually a little surprised to find most of the questions I got were from folks that wanted to know more about Stream Insight and Master Data Services. In past conferences I've been asked a lot of "free consulting" questions, about problems folks have had from older products. I don't mind that a bit - in fact, I'm always happy to help in any way I can. But this time people are really interested in the new features in the product, and I like that they are thinking ahead, not just having to solve problems in production. My presentation was on "Database Design in an Hour". We had the usual fun, and SideShow Bob made an appearance - I kid you not. The guy in the back of the room looked just like Sideshow Bob, so I quickly held a "bes thair" contest, and he won. Duing the presentation, I explain the tools you can use to design databases. I also explain that the "Database Designer" tool in SQL Server Management Studio (SSMS) isn't truly a desinger - it uses non-standard notation, doesn't have a meta-data dictionary, and worst of all, it works at the physical level. In other words, whatever you do in SSMS will automatically change the field/table/relationship structures in the database. We fixed this in SSMS 2008 and higher by adding an option to block that, but the tool is not a good design function nonetheless. To be fair, no one I know of at Microsoft recommends that it is - but I was shocked to hear so many developers in the room defending it as a good tool. I think the main issue for someone who doesn't have to work with Relational Systems a great deal is that it can be difficult to figure out Foreign Keys. The syntax makes them look "backwards", so it's just easier to grab a field and place it on the table you want to point to. There are options. You can download a couple of free tools (CA has a community edition of ER-WIN, Quest has one, and Embarcadero also has one) and if you design more than one or two databases a year, it may be worth buying a true design tool. For years I used Visio, but we changed it so that it doesn't forward-engineer (create the DDL) any more, so it isn't a true design tool either. So investigate those free and not-so-free tools. You'll find they help you in your job - but stay away from the Database Designer in SSMS. Or I'll send Sideshow Bob over there to straighten you out.

• Bay Area Coherence Special Interest Group Next Meeting July 21, 2011

  - by csoto

  Date: Thursday, July 21, 2011 Time: 4:30pm - 8:15pm ET (note that Parking at 475 Sansome Closes at 8:30pm) Where: Oracle Office, 475 Sansome Street, San Francisco, CA Google Map We will be providing snacks and beverages. Register! - Registration is required for building security. Presentation Line Up:? 5:10pm - Batch Processing Using Coherence in Oracle Group Policy Administration - Paul Cleary, Oracle Oracle Insurance Policy Administration (OIPA) is a flexible, rules-based policy administration solution that provides full record keeping for all policy lifecycle transactions. One component of OIPA is Cycle processing, which is the batch processing of pending insurance transactions. This presentation introduces OIPA and Cycle processing, describing the unique challenges of processing a high volume of transactions within strict time windows. It then reviews how OIPA uses Oracle Coherence and the Processing Pattern to meet these challenges, describing implementation specifics that highlight the simplicity and robustness of the Processing Pattern. 6:10pm - Secure, Optimize, and Load Balance Coherence with F5 - Chris Akker, F5 F5 Networks, Inc., the global leader in Application Delivery Networking, helps the world’s largest enterprises and service providers realize the full value of virtualization, cloud computing, and on-demand IT. Recently, F5 and Oracle partnered to deliver a novel solution that integrates Oracle Coherence 3.7 with F5 BIG-IP Local Traffic Manager (LTM). This session will introduce F5 and how you can leverage BIG-IP LTM to secure, optimize, and load balance application traffic generated from Coherence*Extend clients across any number of servers in a cluster and to hardware-accelerate CPU-intensive SSL encryption. 7:10pm - Using Oracle Coherence to Enable Database Partitioning and DC Level Fault Tolerance - Alexei Ragozin, Independent Consultant and Brian Oliver, Oracle Partitioning is a very powerful technique for scaling database centric applications. One tricky part of partitioned architecture is routing of requests to the right database. The routing layer (routing table) should know the right database instance for each attribute which may be used for routing (e.g. account id, login, email, etc): it should be fast, it should fault tolerant and it should scale. All the above makes Oracle Coherence a natural choice for implementing such routing tables in partitioned architectures. This presentation will cover synchronization of the grid with multiple databases, conflict resolution, cross cluster replication and other aspects related to implementing robust partitioned architecture.
