  • How do I (tactfully) tell my project manager or lead developer that the project's codebase needs serious work?

    - by Adam Maras
    I just joined a (relatively) small development team that's been working on a project for several months, if not a year. As with most developer joining a project, I spent my first couple of days reviewing the project's codebase. The project (a medium- to large-sized ASP.NET WebForms internal line of business application) is, for lack of a more descriptive term, a disaster. There are three immediately noticeable problems with the coding standards: The standard is very loose. It describes more of what not to do (don't use Hungarian notation, etc..) than what to do. The standard isn't always followed. There are inconsistencies with the code formatting everywhere. The standard doesn't follow Microsoft's style guidelines. In my opinion, there's no value in deviating from the guidelines that were set forth by the developer of the framework and the largest contributor to the language specification. As for point 3, perhaps it bothers me more because I've taken the time to get my MCPD with a focus on web applications (specifically, ASP.NET). I'm also the only Microsoft Certified Professional on the team. Because of what I learned in all of my schooling, self-teaching, and on-the-job learning (including my preparation for the certification exams) I've also spotted several instances in the project's code where things are simply not done in the best way. I've only been on this team for a week, but I see so many issues with their codebase that I imagine I'll be spending more time fighting with what's already written to do things in "their way" than I would if I were working on a project that, for example, followed more widely accepted coding standards, architecture patterns, and best practices. This brings me to my question: Should I (and if so, how do I) propose to my project manager and team lead that the project needs to be majorly renovated? I don't want to walk into their office, waving my MCTS and MCPD certificates around, saying that their project's codebase is crap. But I also don't want to have to stay silent and have to write kludgey code atop their kludgey code, because I actually want to write quality software and I want the end product to be stable and easily maintainable.

  • Customer Support Spotlight: Clemson University

    - by cwarticki
    I've begun a Customer Support Spotlight series that highlights our wonderful customers and Oracle loyalists.  A week ago I visited Clemson University.  As I travel to visit and educate our customers, I provide many useful tips/tricks and support best practices (as found on my blog and twitter). Most of all, I always discover an Oracle gem who deserves recognition for their hard work and advocacy. Meet George Manley.  George is a Storage Engineer who has worked in Clemson's Data Center all through college, partially in the Hardware Architecture group and partially in the Storage group. George and the rest of the Storage Team work with most all of the storage technologies that they have here at Clemson. This includes a wide array of different vendors' disk arrays, with the most of them being Oracle/Sun 2540's.  He also works with SAM/QFS, ACSLS, and our SL8500 Tape Libraries (all three Oracle/Sun products). (pictured L to R, Matt Schoger (Oracle), Mark Flores (Oracle) and George Manley) George was kind enough to take us for a data center tour.  It was amazing.  I rarely get to see the inside of data centers, and this one was massive. Clemson Computing and Information Technology’s physical resources include the main data center located in the Information Technology Center at the Innovation Campus and Technology Park. The core of Clemson’s computing infrastructure, the data center has 21,000 sq ft of raised floor and is powered by a 14MW substation. The ITC power capacity is 4.5MW.  The data center is the home of both enterprise and HPC systems, and is staffed by CCIT staff on a 24 hour basis from a state of the art network operations center within the ITC. A smaller business continuance data center is located on the main campus.  The data center serves a wide variety of purposes including HPC (supercomputing) resources which are shared with other Universities throughout the state, the state's medicaid processing system, and nearly all other needs for Clemson University. Yes, that's no typo (14,256 cores and 37TB of memory!!! Thanks for the tour George and thank you very much for your time.  The tour was fantastic. I enjoyed getting to know your team and I look forward to many successes from Clemson using Oracle products. -Chris WartickiGlobal Customer Management

  • PASS 13 Dispatches: moving to the cloud

    - by Tony Davis
    PASS Summit 13, Day 1 keynote by Quentin Clarke and we're hearing about “redefiniing mission critical in the cloud”. With a move to the Windows Azure cloud comes the promise of capacity on demand, automatic HA, backups, patching and so on, as well as passing responsibility to MS for managing hardware, upgrades and so on. However, for many databases and applications the best route to the cloud is not necessarily obvious. For most, the path of least resistance is IaaS – SQL Server in a Azure VM. It removes the hardware burden but you still have to manage your databases and implementing HA for SQL Server is your responsibility. Also, scaling up comes at quite a cost – the biggest VM (8 CPU cores, 56 GB RAM, 16 1TB drives with 500 IOPS each) weighs in at over over $4500 per month. With PaaS, in the form of Windows SQL Database, you get a “3-copies replica set” so HA comes out-of the box, and removes the majority of the administration burden, but you are moving your database into a very different environment. For a start, it's a shared environment, with other customers using the same compute nodes in the cluster, and potentially even sharing the same database (multi-tenancy). Unless you pay for SQL DB Premium edition, the resources available for your workload will depends on how nicely others “play” in the shared environment. You'll potentially need to do a lot of tuning, and application rewriting to avoid throttling issues, optimising application-database communication to deal with increased latency between the two, and so on. You'll need aggressive application caching. You'll also need retry logic and to deal with (expected) node failure and the need to reconnect. In Tuesday's PASS Summit pre-con from the SQLCAT team, they spent a lot of time covering some of the telemetric techniques (collect into Azure storage the necessary monitoring data) to perform capacity planning, work out the hotspots and bottlenecks in your cloud applications. Tools like WAD (Windows Azure Diagnostics), performance counters SQL Database DMVs, and others, will be essential. Of course, to truly exploit the vast horizontal scaling that is available from the existence of thousands of compute nodes, you'll also need to need to consider how to “shard” your data so Azure can move it between nodes at will. Finding the right path to the Cloud isn't easy, but it's coming. I spoke to people one year ago who saw no real benefit in trying to move their infrastructure and databases to the cloud, but now at their company, it's the conversation that won't go away. Tony.

  • Tellago announces SQL Server 2008 R2 BI quick adoption programs

    - by Vishal
    During the last year, we (Tellago) have been involved in various business intelligence initiatives that leverage some emerging BI techniques such as self-service BI or complex event processing (CEP). Specifically, in the last few months, we have partnered with Microsoft to deliver a series of events across the country where we present the different technologies of the SQL Server 2008 R2 BI stack such as PowerPivot, StreamInsight, Ad-Hoc Reporting and Master Data Services. As part of those events, we try to go beyond the traditional technology presentation and provide a series of best practices and lessons we have learned on real world BI projects that leverage these technologies. Now that SQL Server 2008 R2 has been released to manufacturing, we have launched a series of quick adoption programs that are designed to help customers understand how they can embrace the newest additions to Microsoft's BI stack as part of their IT initiatives. The programs are also designed to help customers understand how the new SQL Server features interact with established technologies such as SQL Server Analysis Services or SQL Server Integration Services. We try to keep these adoption programs very practical by doing a lot of prototyping and design sessions that will give our customers a practical glimpse of the capabilities of the technologies and how they can fit in their enterprise architecture roadmap. Here is our official announcement (you can blame my business partner, BI enthusiast, and Tellago's CEO Elizabeth Redding for the marketing pitch ;)): Tellago Marks Microsoft's SQL Server 2008 R2 Launch With Business Intelligence Quick Adoption Program Microsoft launched SQL Server 2008 R2 last week, which delivers several breakthrough business intelligence (BI) capabilities that enable organizations to:  Efficiently process, analyze and mine data Improve IT and developer efficiency Enable highly scalable and well-managed Business Intelligence on a self-service basis for business users The release offers a new feature called PowerPivot, which enables self service BI through connecting business users directly to enterprise data sources and providing improved reporting and analytics. The release also offers Master Data Management which helps enterprises centrally manage critical data assets company-wide and across diverse systems, enabling increased integrity of information over time. Finally, the release includes StreamInsight, which is a framework for implementing Complex Event Processing (CEP) applications on the Microsoft platform. With StreamInsight, IT organizations can implement the infrastructure to process a large volume of events near real time, execute continuous queries against event streams and enable real time business intelligence. As a thought leader in the Business Intelligence community, Tellago has recognized the occasion by launching a series of quick adoption programs to enable the adoption of this new BI technology stack in your enterprise. Our Quick Adoption programs are designed to help you: Brainstorm BI solution options  Architect initial infrastructure components Prototype key features of a solution As a 2-3 day program, our approach is more efficient and cost effective than a traditional Proof of Concept because it allows you to understand the new SQL Server 2008 R2 feature set  while seeing directly how you can leverage it for your business intelligence needs. If you are interested in learning more about the BI capabilities of Microsoft's Business Intelligence stack, including SQL Server 2008 R2, we can help.  As industry experts and software content advisers to Microsoft, Tellago is the place where ideas meet technology expertise.  Let us help you see for yourself the advantages that you can gain from Microsoft's  SQL Server 2008 R2.

    TechED is the event which I am always excited about. It is one of the largest technology in India. Microsoft Tech Ed India 2011 is the premier technical education and networking event for tech professionals interested in learning, connecting and exploring a broad set of current and soon-to-be released Microsoft technologies, tools, platforms and services. I am going to speak at the TechED on two very interesting and advanced subjects. Venue: The LaLiT Ashok Kumara Krupa High Grounds Bangalore – 560001, Karnataka, India Sessions Date: March 25, 2011 Understanding SQL Server Behavioral Pattern – SQL Server Extended Events Date and Time: March 25, 2011 12:00 PM to 01:00 PM History repeats itself! SQL Server 2008 has introduced a very powerful, yet very minimal reoccurring feature called Extended Events. This advanced session will teach experienced administrators’ capabilities that were not possible before. From T-SQL error to CPU bottleneck, error login to deadlocks –Extended Event can detect it for you. Understanding the pattern of events can prevent future mistakes. SQL Server Waits and Queues – Your Gateway to Perf. Troubleshooting Date and Time: March 25, 2011 04:15 PM to 05:15 PM Just like a horoscope, SQL Server Waits and Queues can reveal your past, explain your present and predict your future. SQL Server Performance Tuning uses the Waits and Queues as a proven method to identify the best opportunities to improve performance. A glance at Wait Types can tell where there is a bottleneck. Learn how to identify bottlenecks and potential resolutions in this fast paced, advanced performance tuning session. My session will be on the third day of the event and I am very sure that everybody will be in groove to learn new interesting subjects. I will have few give-away during and at the end of the session. I will not tell you what I will have but it will be for sure something you will love to have. Please make a point and reserve above time slots to attend my session.

  • Brendan Gregg's "Systems Performance: Enterprise and the Cloud"

    - by user12608550
    Long ago, the prerequisite UNIX performance book was Adrian Cockcroft's 1994 classic, Sun Performance and Tuning: Sparc & Solaris, later updated in 1998 as Java and the Internet. As Solaris evolved to include the invaluable DTrace observability features, new essential performance references have been published, such as Solaris Performance and Tools: DTrace and MDB Techniques for Solaris 10 and OpenSolaris (2006)  by McDougal, Mauro, and Gregg, and DTrace: Dynamic Tracing in Oracle Solaris, Mac OS X and FreeBSD (2011), also by Mauro and Gregg. Much has occurred in Solaris Land since those books appeared, notably Oracle's acquisition of Sun Microsystems in 2010 and the demise of the OpenSolaris community. But operating system technologies have continued to improve markedly in recent years, driven by stunning advances in multicore processor architecture, virtualization, and the massive scalability requirements of cloud computing. A new performance reference was needed, and I eagerly waited for something that thoroughly covered modern, distributed computing performance issues from the ground up. Well, there's a new classic now, authored yet again by Brendan Gregg, former Solaris kernel engineer at Sun and now Lead Performance Engineer at Joyent. Systems Performance: Enterprise and the Cloud is a modern, very comprehensive guide to general system performance principles and practices, as well as a highly detailed reference for specific UNIX and Linux observability tools used to examine and diagnose operating system behaviour.  It provides thorough definitions of terms, explains performance diagnostic Best Practices and "Worst Practices" (called "anti-methods"), and covers key observability tools including DTrace, SystemTap, and all the traditional UNIX utilities like vmstat, ps, iostat, and many others. The book focuses on operating system performance principles and expands on these with respect to Linux (Ubuntu, Fedora, and CentOS are cited), and to Solaris and its derivatives [1]; it is not directed at any one OS so it is extremely useful as a broad performance reference. The author goes beyond the intricacies of performance analysis and shows how to interpret and visualize statistical information gathered from the observability tools.  It's often difficult to extract understanding from voluminous rows of text output, and techniques are provided to assist with summarizing, visualizing, and interpreting the performance data. Gregg includes myriad useful references from the system performance literature, including a "Who's Who" of contributors to this great body of diagnostic tools and methods. This outstanding book should be required reading for UNIX and Linux system administrators as well as anyone charged with diagnosing OS performance issues.  Moreover, the book can easily serve as a textbook for a graduate level course in operating systems [2]. [1] Solaris 11, of course, and Joyent's SmartOS (developed from OpenSolaris) [2] Gregg has taught system performance seminars for many years; I have also taught such courses...this book would be perfect for the OS component of an advanced CS curriculum.

  • Victor Grazi, Java Champion!

    - by Tori Wieldt
    Congratulations to Victor Grazi, who has been made a Java Champion! He was nominated by his peers and selected as a Java Champion for his experience as a developer, and his work in the Java and Open Source communities. Grazi is a Java evangelist and serves on the Executive Committee of the Java Community Process, representing Credit Suisse - the first non-technology vendor on the JCP. He also arranges the NY Java SIG meetings at Credit Suisse's New York campus each month, and he says it has been a valuable networking opportunity. He also is the spec lead for JSR 354, the Java Money and Currency API. Grazi has been building real time financial systems in Java since JDK version 1.02! In 1996, the internet was just starting to happen, Grazi started a dot com called Supermarkets to Go, that provided an on-line shopping presence to supermarkets and grocers. Grazi wrote most of the code, which was a great opportunity for him to learn Java and UI development, as well as database management. Next, he went to work at Bank of NY building a trading system. He studied for Java certification, and he noted that getting his certification was a game changer because it helped him started to learn the nuances of the Java language. He has held other development positions, "You may have noticed that you don't get as much junk mail from Citibank as you used to - that is thanks to one of my projects!" he told us. Grazi joined Credit Suisse in 2005 and is currently Vice President on the central architecture team. Grazi is proud of his open source project, Java Concurrent Animated, a series of animations that visualize the functionality of the components in the java.util.concurrent library. "It has afforded me the opportunity to speak around the globe" and because of it, has discovered that he really enjoys doing public presentations. He is a fine addition to the Java Champions program. The Java Champions are an exclusive group of passionate Java technology and community leaders who are community-nominated and selected under a project sponsored by Oracle. Nominees are named and selected through a peer review process. Java Champions get the opportunity to provide feedback, ideas, and direction that will help Oracle grow the Java Platform. This interchange may be in the form of technical discussions and/or community-building activities with Oracle's Java Development and Developer Program teams.

  • java+netbeans+mysql+ubuntu 64 bits LTS VS C#+MS SQL for fast develop trading system

    - by crunchor
    I am going to build a trading system and use with the broker "Interactive Broker" API. The API supports C++ Socket, Java Socket, DDE, Active X APIs in Windows. The API supports Java Socket API, Posix C++ Socket API in Unix kind like Ubuntu. My trading system has some real time long calculations to do and a lot of maths for backtest. I am using a retail trading program Amibroker which is written in C++ and I run it in windows xp 32 bits, it will take me days to do one serious backtest with my G620 Sandy Bridge CPU and 3GB of ram. So for my trading system, I need to have 1. speed, 2. stability, 3. fast development I have done some research, C++ is fastest but I am not good at it and it takes much longer time to develop. Other than C++, Java in linux has the best speed. I also did some research for database and look like mysql has the best speed. Mysql and PostgreSQL both are very popular open source sql db, which one should I choose? I see MySQL has Workbench now which looks like similar to MS SQL management studio so look like a good start. Netbeans should be the most popular Java IDE now and seem like its GUI design can be as easy as Virtual Studio now. I am not sure if made by Netbeans would affect the speed and if its GUI design is really that good and easy to use. Ubuntu 64 bits LTS has good long term support, good community support, and stable. I will buy a new computer if I can create a good trading system for live trading and backtest. Very likely I will buy a I7 or I5 depends on if I7 can really have better speed for my case. Actually I mainly deal with C# in my jobs and I just knew java but not good at java. What would you guys recommend? Any better solution? This will be a big project and very likely life long project for me so I seriously do research including asking you guys before I start and focus on what I should, thanks!

  • Ubuntu server spontaneous reboot

    - by user1941407
    I have got two ubuntu 12.04 servers(xeon e3). Sometimes(several days) each server spontaneously reboots. HDDs and other hardware are ok. Which logfile can help find a reason of the problem? UPDATED. hardware: xeon e3 processor, intel server motherboard, 32gb ddr3 ecc, mdadm mirror hdd raid for system, mdadm ssd raid for database(postgres).

  • Oracle Solaris at the OpenStack Summit in Atlanta

    - by Glynn Foster
    I had the fortune of attending my 2nd OpenStack summit in Atlanta a few weeks ago and it turned out to be a really excellent event. Oracle had many folks there this time around across a variety of different engineering teams - Oracle Solaris, Oracle ZFSSA, Oracle Linux, Oracle VM and more. Really great to see continuing momentum behind the project and we're very happy to be involved. Here's a list of the highlights that I had during the summit: The operators track was a really excellent addition, with a chance for users/administrators to voice their opinions based on experiences. Really good to hear how OpenStack is making businesses more agile, but also equally good to hear about some of the continuing frustrations they have (fortunately many of them are new and being addressed). Seeing this discussion morph into a "Win the enterprise" working group is also very pleasing. Enjoyed Troy Toman's keynote (Rackspace) about designing a planet scale cloud OS and the interoperability challenges ahead of us. I've been following some of the discussion around DefCore for a bit and while I have some concerns, I think it's mostly heading in the right direction. Certainly seems like there's a balance to strike to ensure that this effects the OpenStack vendors in such a way as to avoid negatively impacting our end users. Also enjoyed Toby Ford's keynote (AT&T) about his desire for a NVF (Network Function Virtualization) architecture. What really resonated was also his desire for OpenStack to start addressing the typical enterprise workload, being less like cattle and more like pets. The design summit was, as per usual, pretty intense for - definitely would get more value from these if I knew the code base a little better. Nevertheless, attended some really great sessions and got a better feeling of the roadmap for Juno. Markus Flierl gave a great presentation (see below) at the demo theatre for what we're doing with OpenStack on Oracle Solaris (and more widely at Oracle across different products). Based on the discussions that we had at the Oracle booth, there's a huge amount of interest there and we talked to some great customers during the week about their thoughts and directions in this respect. Undoubtedly Atlanta had some really good food. Highlights were the smoked ribs and brisket and the SweetWater brewing company. That said, I also loved the fried chicken, fried green tomatoes and collared greens, and wonderful hosting of "big momma" at Pitty Pat's Porch. Couldn't quite bring myself to eat biscuits and gravy in the morning though. Visiting the World of Coca-Cola just before flying out. A total brain washing exercise, but very enjoyable. And very much liked Beverly (contrary to many other opinions on the internet) - but then again, I'd happily drink tonic water every day of the year... Looking forward to Paris in November!

  • Inverted schedctl usage in the JVM

    - by Dave
    The schedctl facility in Solaris allows a thread to request that the kernel defer involuntary preemption for a brief period. The mechanism is strictly advisory - the kernel can opt to ignore the request. Schedctl is typically used to bracket lock critical sections. That, in turn, can avoid convoying -- threads piling up on a critical section behind a preempted lock-holder -- and other lock-related performance pathologies. If you're interested see the man pages for schedctl_start() and schedctl_stop() and the schedctl.h include file. The implementation is very efficient. schedctl_start(), which asks that preemption be deferred, simply stores into a thread-specific structure -- the schedctl block -- that the kernel maps into user-space. Similarly, schedctl_stop() clears the flag set by schedctl_stop() and then checks a "preemption pending" flag in the block. Normally, this will be false, but if set schedctl_stop() will yield to politely grant the CPU to other threads. Note that you can't abuse this facility for long-term preemption avoidance as the deferral is brief. If your thread exceeds the grace period the kernel will preempt it and transiently degrade its effective scheduling priority. Further reading : US05937187 and various papers by Andy Tucker. We'll now switch topics to the implementation of the "synchronized" locking construct in the HotSpot JVM. If a lock is contended then on multiprocessor systems we'll spin briefly to try to avoid context switching. Context switching is wasted work and inflicts various cache and TLB penalties on the threads involved. If context switching were "free" then we'd never spin to avoid switching, but that's not the case. We use an adaptive spin-then-park strategy. One potentially undesirable outcome is that we can be preempted while spinning. When our spinning thread is finally rescheduled the lock may or may not be available. If not, we'll spin and then potentially park (block) again, thus suffering a 2nd context switch. Recall that the reason we spin is to avoid context switching. To avoid this scenario I've found it useful to enable schedctl to request deferral while spinning. But while spinning I've arranged for the code to periodically check or poll the "preemption pending" flag. If that's found set we simply abandon our spinning attempt and park immediately. This avoids the double context-switch scenario above. One annoyance is that the schedctl blocks for the threads in a given process are tightly packed on special pages mapped from kernel space into user-land. As such, writes to the schedctl blocks can cause false sharing on other adjacent blocks. Hopefully the kernel folks will make changes to avoid this by padding and aligning the blocks to ensure that one cache line underlies at most one schedctl block at any one time.

  • What is the start point in game development? Where to start?

    - by Dragon
    I understand, I'm not unique with such a question, there are a lot of questions like this one. But I hope you'll take a minute and maybe can give me a piece of advice. I have an idea to develop games, but I don't know where is the start point in game development. The learning curve isn't as straight as in learning of a programming language, but I want to give it a try. I have some experience with OOP and programming in general. I know (not too deep) C#, Java programming languages. I searched info on where to start, read a lot of blogs, forums and so on. Once I decided "stop wandering around, just start develop a game" and I started. At the moment I have a console version of very simple game (RPS - rock-paper-scissors) developed with C#. It has different modes: "player vs cpu" and "player vs player". Some time later I looked at the code and decided that it should be refactored or even redeveloped from the scratch. And I thought that time "GUI is what I need. I can add logic later." And now I'm here. I've already decided to make RPS with GUI, then make multiplayer and so on. I'm not thinking about 3D now, 2D is enough. It doesn't matter what language to use: C# or Java, I found frameworks for both - XNA (C#) and Slick (Java). Both are good for 2D game development. But I know nothing about sprites, how to bind objects on the screen and so on. You can say "you don't need it for such simple game like RPS", but RPS is the beginning, I have some ideas like "Tower Defense" game... you know, everybody has ideas, wishes.... and this knowledge is useful and in some way obligatory. So what is the start point to achieve my plans, ideas, wishes? Where to start? Is it possible to make game development learning curve a little bit straight? Or there're ways that amateur and game development beginners use for years? Thank you for you answers and advise in advance. P.S Sorry for that this post turned out an essay, but I tried to express my wish to start acting. Hope I managed to do it.

  • Media keys play/pause globally worked in 12.10, not in 13.10

    - by Stéphane Gourichon
    Laptop media keys On Asus n55sf laptop, there are a dedicated keys for volume up, volume down, mute, [play/pause], stop, launch (plus a dozen Fn-key combinations). In 12.10 most worked. (Overall is seems unrelated to desktop environment used, stating it for the sake of completeness.) On Ubuntu 12.10 under XFCE they just worked. That is: when a player like rhythmbox or totem was started, it would alternate between play and pause. Interestingly, if several were started, they would alternate independently. E.g. use mouse to pause rhythmbox, launch totem, and one hit on [play/pause] key would pause one and resume the other. Keys Next,Previous and Stop worked as expected in any program. In 13.10 most still work, but play/skip related ignored. On Xubuntu 13.10 (XFCE too) the volume keys work but the [play/pause], stop, next and prev are ignored. Not tried regular Ubuntu 13.10 (Unity). Search before you ask Here are a few facts: https://wiki.ubuntu.com/Hotkeys/Architecture is ummutable and mentions Ubuntu 9.10. https://wiki.ubuntu.com/Hotkeys/Troubleshooting is also outdated as it mentions /usr/share/doc/udev/README.keymap.txt which no longer exists. On 12.10 and 13.10 versions, at XFCE level (as visible by xfconf-query or using xfce4-settings-manager) there are a couple of shortcut for keys like XF86Calculator or XF86TouchpadToggle but nothing related to volume prev/next/play/stop, which is okay. XF86Audio substring doesn't appear in /etc (which is normal) Kernel-level test: "showkey -s" on console shows that keys Next,Play/Pause,Previous,Stop are keycodes 163,164,165,166. Nothing relevant in /etc about that. Reports https://bugs.launchpad.net/ubuntu/+source/udev/+bug/1072371 and https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1012365 suggest to adjust at udev level. Alas, the udev tutorials I found ( e.g. https://wiki.debian.org/udev ) don't even mention keyboard. A thread in french seems to deal with a similar issue: https://forum.ubuntu-fr.org/viewtopic.php?id=1395051. @sudo evtest /dev/input/event3@, in X as well as on plain console, reports events on key pressed and repeats, but nothing when pressing those media keys. Is udev a dead end ? Questions How did it work in 12.10 ? Through udev ? Something else ? Any other hint ?

  • How one decision can turn web services to hell

    - by DigiMortal
    In this posting I will show you how one stupid decision may turn developers life to hell. There is a project where bunch of complex applications exchange data frequently and it is very hard to change something without additional expenses. Well, one analyst thought that string is silver bullet of web services. Read what happened. Bad bad mistake In the early stages of integration project there was analyst who also established architecture and technical design for web services. There was one very bad mistake this analyst made: All data must be converted to strings before exchange! Yes, that’s correct, this was the requirement. All integers, decimals and dates are coming in and going out as strings. There was also explanation for this requirement: This way we can avoid data type conversion errors! Well, this guy works somewhere else already and I hope he works in some burger restaurant – far away from computers. Consequences If you first look at this requirement it may seem like little annoying piece of crap you can easily survive. But let’s see the real consequences one stupid decision can cause: hell load of data conversions are done by receiving applications and SSIS packages, SSIS packages are not error prone and they depend heavily on strings they get from different services, there are more than one format per type that is used in different services, for larger amounts of data all these conversion tasks slow down the work of integration packages, practically all developers have been in hurry with some SSIS import tasks and some fields that are not used in different calculations in SSAS cube are imported without data conversions (by example, some prices are strings in format “1.021 $”). The most painful problem for developers is the part of data conversions because they don’t expect that there is such a stupid requirement stated and therefore they are not able to estimate the time their tasks take on these web services. Also developers must be prepared for cases when suddenly some service sends data that is not in acceptable format and they must solve the problems ASAP. This puts unexpected load on developers and they are not very happy with it because they can’t understand why they have to live with this horror if it is possible to fix. What to do if you see something like this? Well, explain the problem to customer and demand special tasks to project schedule to get this mess solved before going on with new developments. It is cheaper to solve the problems now that later.

  • Oracle WebCenter: Social Networking & Collaboration

    - by kellsey.ruppel(at)oracle.com
    We’ve talked in previous weeks about the key goals of the new release of WebCenter are providing a Modern User Experience, unparalleled Application Integration, converging all the best of the existing portal platforms into WebCenter and delivering a Common User Experience Architecture.  We’ve provided an overview of Oracle WebCenter and discussed some of the other key goals in previous weeks, and this week, we’ll focus on how the new release of Oracle WebCenter provides unprecedented Social Networking and Collaboration.We recently talked with Carin Chan, Principal Product Manager at Oracle, around the topic of Social Networking and Collaboration. In today’s work environment, employees have come to expect social and collaborative services to augment their work environment. Whether it is to post a blog or to poll fellow coworkers, employees expect and demand access to highly integrated, collaborative work environments that allow them to quickly contribute at work -- whether it is to make informed decisions, contribute on projects, or share knowledge.Social and collaborative services from Oracle WebCenter add an immeasurable amount of value to achieving a modern user experience. Oracle WebCenter Services provides rich and comprehensive social computing services that include services such as wikis, blogs, instant messaging, presence, activity streams and graphs, and polls/surveys that offer employees access to rich collaborative services to work efficiently.Employees can create pages or spaces that mix and match collaborative services while bringing in data from other applications to share with groups, teams, or organizations. These out of the box social and collaborative services include: People Connections and Activity Streams enable users to quickly assemble and visualize their social business networks and track user activities.Activity Graphs tracks all user activities in real-time and gathers intelligence about these users, their connections and the way they use information to make educated recommendations and provide on the spot information discovery.Wikis and blogs enable the community authoring of documents and sharing of ideas and also allow for the gathering of feedback and comments on those ideas.Tags and links allow users to easily mark, connect and share information with others.RSS feeds are available to track new or changed information related to discussion forums, processes or activities in an Oracle WebCenter environment.Discussion forums enable sharing of group knowledge and easy creation of communities around specific topics.Announcements allow you to manage and publish important news to your user base.Instant Messaging and Presence enable real-time awareness and communication with available users in the context of a business task.Web and Voice Conferencing enables real-time communication with internal and external business users.Lists provide a way to manage list data directly on the web as well as export and import it from and to Microsoft Excel.Oracle WebCenter Analytics provides comprehensive reporting metrics on activity and content usage within portals or composite applications.Activity Streams allow you to track activities and visualize your business networks.While being able to integrate into your portal deployment, these services are also integrated into how users are already working. This includes integration with software such as Microsoft Outlook, Microsoft Office and mobile devices such as the Apple iPhone. These services are just a tip of the iceberg regarding social and collaborative services that Oracle WebCenter has to offer your employees. Be sure to keep checking back this week for in future posts, we’ll delve deeper into a few of these collaborative services and discuss how a combination of collaborative services offer a better portal deployment to empower business users.

  • System Variables, Stored Procedures or Functions for Meta Data

    - by BuckWoody
    Whenever you want to know something about SQL Server’s configuration, whether that’s the Instance itself or a database, you have a few options. If you want to know “dynamic” data, such as how much memory or CPU is consumed or what a particular query is doing, you should be using the Dynamic Management Views (DMVs) that you can read about here: http://msdn.microsoft.com/en-us/library/ms188754.aspx  But if you’re looking for how much memory is installed on the server, the version of the Instance, the drive letters of the backups and so on, you have other choices. The first of these are system variables. You access these with a SELECT statement, and they are useful when you need a discrete value for use, say in another query or to put into a table. You can read more about those here: http://msdn.microsoft.com/en-us/library/ms173823.aspx You also have a few stored procedures you can use. These often bring back a lot more data, pre-formatted for the screen. You access these with the EXECUTE syntax. It is a bit more difficult to take the data they return and get a single value or place the results in another table, but it is possible. You can read more about those here: http://msdn.microsoft.com/en-us/library/ms187961.aspx Yet another option is to use a system function, which you access with a SELECT statement, which also brings back a discrete value that you can use in a test or to place in another table. You can read about those here: http://msdn.microsoft.com/en-us/library/ms187812.aspx  By the way, many of these constructs simply query from tables in the master or msdb databases for the Instance or the system tables in a user database. You can get much of the information there as well, and there are even system views in each database to show you the meta-data dealing with structure – more on that here: http://msdn.microsoft.com/en-us/library/ms186778.aspx  Some of these choices are the only way to get at a certain piece of data. But others overlap – you can use one or the other, they both come back with the same data. So, like many Microsoft products, you have multiple ways to do the same thing. And that’s OK – just research what each is used for and how it’s intended to be used, and you’ll be able to select (pun intended) the right choice.
