• Change Desktop Resolution With a Keyboard Shortcut

  - by Matthew Guay

  Do you find yourself changing your monitor resolution several times a day?  If so, you might like this handy way to set a keyboard shortcut for your most-used resolutions. Most users rarely have to change their screen resolution often, as LCD monitors usually only look best at their native resolution.  But netbooks present a unique situation, as their native resolution is usually only 1024×600.  Some newer netbooks offer higher resolutions which may not looks as crisp as the native resolution but can be handy for using a program that expects a higher resolution.  This is the perfect situation for a keyboard shortcut to help you change the resolution without having to hassle with dialogs and menus each time, and HRC – HotKey Resolution Changer makes it easy to do. Create Keyboard Shortcuts Download the HRC – HotKey Resolution Changer (link below), unzip, and then run HRC.exe in the folder. This will start a tray icon, and will not automatically open the HRC window.  You don’t have to install HRC.  Double-click the tray icon to open it.  Note: Windows 7 automatically hides new tray icons, so if you can’t see it, click the arrow to see the hidden tray icons. By default, HRC will show two entries with your default resolutions, color depth, and refresh rate. Add a keyboard shortcut by clicking the Change button over the resolution.  Press the keyboard shortcut you want to press to switch to that resolution; we entered Ctrl+Alt+1 for our default resolution.  Make sure not to use a keyboard shortcut you use in another application, as this will override it.  Click Set when you’ve entered the hotkey(s) you want. Now, on the second entry, select the resolution you want for your alternate resolution.  The drop-down list will only show your monitor’s supported resolutions, so you don’t have to worry about choosing an incorrect resolution.  You can also set a different color depth or refresh rate for this resolution.  Now add a keyboard shortcut for this resolution as well. You can set keyboard shortcuts for up to 9 different resolutions with HRC.  Click the Select number of HotKeys button on the left, and choose the number of resolutions you want to set.  Here we have unique keyboard shortcuts for our three most-used resolutions on our netbook. HRC must be kept running to use the keyboard shortcuts, so click the Minimize to tray icon which is the second icon to the right.  This will keep it running in the tray. If you want to be able to change your resolution anytime, you’ll want HRC to automatically start with Windows.  Create a shortcut to HRC, and paste it into your Windows startup folder.  You can easily open this folder by entering the following in the Run command or in the address bar in Explorer: %appdata%\Microsoft\Windows\Start Menu\Programs\Startup   Conclusion HRC- HotKey Resolution Changer gives you a great way to quickly change your screen resolution with a keyboard shortcut.  Whether or not you love keyboard shortcuts, this is still a much easier way to switch between your most commonly used resolutions.

• SQL Server – SafePeak “Logon Trigger” Feature for Managing Data Access

  - by pinaldave

  Lately I received an interesting question about the abilities of SafePeak for SQL Server acceleration software: Q: “I would like to use SafePeak to make my CRM application faster. It is an application we bought from some vendor, after a while it became slow and we can’t reprogram it. SafePeak automated caching sounds like an easy and good solution for us. But, in my application there are many servers and different other applications services that address its main database, and some even change data, and I feel that there is a chance that some servers that during the connection process we may miss some. Is there a way to ensure that SafePeak will be aware of all connections to the SQL Server, so its cache will remain intact?” Interesting question, as I remember that SafePeak (http://www.safepeak.com/Product/SafePeak-Overview) likes that all traffic to the database will go thru it. I decided to check out the features of SafePeak latest version (2.1) and seek for an answer there. A: Indeed I found SafePeak has a feature they call “Logon Trigger” and is designed for that purpose. It is located in the user interface, under: Settings -> SQL instances management  ->  [your instance]  ->  [Logon Trigger] tab. From here you activate / deactivate it and control a white-list of enabled server IPs and Login names that SafePeak will ignore them. Click to Enlarge After activation of the “logon trigger” Safepeak server is notified by the SQL Server itself on each new opened connection. Safepeak monitors those connections and decides if there is something to do with them or not. On a typical installation SafePeak likes all application and users connections to go via SafePeak – this way it knows about data and schema updates immediately (real time). With activation of the safepeak “logon trigger”  a special CLR trigger is deployed on the SQL server and notifies Safepeak on any connection that has not arrived via SafePeak. In such cases Safepeak can act to clear and lock the cache or to ignore it. This feature enables to make sure SafePeak will be aware of all connections so SafePeak cache will maintain exactly correct all times. So even if a user, like a DBA will connect to the SQL Server not via SafePeak, SafePeak will know about it and take actions. The notification does not impact the work of that connection, the user or application still continue to do whatever they planned to do. Note: I found that activation of logon trigger in SafePeak requires that SafePeak SQL login will have the next permissions: 1) CONTROL SERVER; 2) VIEW SERVER STATE; 3) And the SQL Server instance is CLR enabled; Seeing SafePeak in action, I can say SafePeak brings fantastic resource for those who seek to get performance for SQL Server critical apps. SafePeak promises to accelerate SQL Server applications in just several hours of installation, automatic learning and some optimization configuration (no code changes!!!). If better application and database performance means better business to you – I suggest you to download and try SafePeak. The solution of SafePeak is indeed unique, and the questions I receive are very interesting. Have any more questions on SafePeak? Please leave your question as a comment and I will try to get an answer for you.

• Increase the size of Taskbar Preview Thumbnails in Windows 7

  - by Matthew Guay

  Taskbar thumbnail previews are incredibly useful in Windows 7, but for some users they may be too small.  Here’s a tool to help you make your taskbar thumbnail previews just like you want them. A few years ago we featured a tool to increase the size of your thumbnail previews in Windows Vista, but unfortunately this application doesn’t work correctly in Windows 7.  However, there is a new tool for Windows 7 that lets you customize your taskbar thumbnail previews even more in Windows 7.  With it, you can change almost anything about your taskbar thumbnail previews.  The default taskbar thumbnails are nice, but may be too small for users with vision problems or with very high resolution monitors.  Whatever your need, this is a great tool to make the thumbnails looks and work just like you want. Let’s get started Download the Windows 7 Taskbar Thumbnail Customizer (link below), and unzip the files.  Run the Windows 7 Taskbar Thumbnail Customizer when you’re done.  Simply double-click on it; you don’t need to run it as administrator. Now, you change the size, spacing, margin, and delay time of your taskbar thumbnails.  The Delay Time setting is very handy; to speed things up, we set it to 0 so there’s no delay between when you mouse-over a taskbar icon to when you see the thumbnail.  Simply drag the slider to the size (or time in the delay settings) you want, and click Apply settings.  Windows Explorer will automatically restart, and your new taskbar thumbnails will be ready to use. Here is the default Windows 7 thumbnail preview of a video playing in Media player: And here’s the taskbar thumbnail enlarged to 380px.  Now you can really watch a video from your taskbar thumbnail. The larger taskbar thumbnails show up a little different in Internet Explorer.  It shows a larger preview of your active tab, and smaller previews of your other tabs.  Notice also that Aero peek shows the tab you’re hovering over in Internet Explorer, but the tab name in IE’s toolbar doesn’t change to the one you’re previewing.   Here we increased the width between the thumbnails, while keeping the thumbnails at their default size.  This could be useful if you have trouble selecting the correct preview, and we can imagine it would be a very useful modification on touch screens. And, if you ever take your changes too far, and want to revert to your default Windows 7 taskbar thumbnail previews, simply run the Customizer again and select Restore Defaults.  Windows Explorer will restart again, and your taskbar thumbnails will be back to their default settings.   Conclusion This tool makes it safe and easy to change the size, spacing, and more of your taskbar thumbnail previews.  And since you can always revert to the default settings, you can experiment without fear of messing up your computer.  If you’d prefer to change the settings manually without using a dedicated application, here’s a list of the registry changes you can make to accomplish this by hand.

• Craig Mundie's video

  - by GGBlogger

  Timothy recently posted “Microsoft Shows Off Radical New UI, Could Be Used In Windows 8” on Slashdot. I took such grave exception to his post that I found it necessary to my senses to write this blog. We need to go back many years to the days of hand cranked calculators and early main frame computers. These devices had singular purposes – they were “number crunchers” used to make accounting easier. The front facing display in early mainframes was “blinken lights.” The calculators did provide printing – in the form of paper tape and the mainframes used line printers to generate reports as needed. We had other metaphors to work with. The typewriter was/is a mechanical device that substitutes for a type setting machine. The originals go back to 1867 and the keyboard layout has remained much the same to this day. In the earlier years the Morse code telegraphs gave way to Teletype machines. The old ASR33, seen on the left in this photo of one of the first computers I help manufacture, used a keyboard very similar to the keyboards in use today. It also generated punched paper tape that we generated to program this computer in machine language. Everything considered this computer which dates back to the late 1960s has a keyboard for input and a roll of paper as output. So in a very rudimentary fashion little has changed. Oh – we didn’t have a mouse! The entire point of this exercise is to point out that we still use very similar methods to get data into and out of a computer regardless of the operating system involved. The Altair, IMSAI, Apple, Commodore and onward to our modern machines changed the hardware that we interfaced to but changed little in the way we input, view and output the results of our computing effort. The mouse made some changes and the advent of windowed interfaces such as Windows and Apple made things somewhat easier for the user. My 4 year old granddaughter plays here Dora games on our computer. She knows how to start programs, use the mouse, play the game and is quite adept so we have come some distance in making computers useable. One of my chief bitches is the constant harangues leveled at Microsoft. Yup – they are a money making organization. You like Apple? No problem for me. I don’t use Apple mostly because I’m comfortable in the Windows environment but probably more because I don’t like Apple’s “Holier than thou” attitude. Some think they do superior things and that’s also fine with me. Obviously the iPhone has not done badly and other Apple products have fared well. But they are expensive. I just build a new machine with 4 Terabytes of storage, an Intel i7 Core 950 processor and 12 GB of RAMIII. It cost me – with dual monitors – less than 2000 dollars. Now to the chief reason for this blog. I’m going to continue developing software for as long as I’m able. For that reason I don’t see my keyboard, mouse and displays changing much for many years. I also don’t think Microsoft is going to spoil that for me by making radical changes to my developer experience. What Craig Mundie does in his video here:  http://www.ispyce.com/2011/02/microsoft-shows-off-radical-new-ui.html is explore the potential future of computer interfaces for the masses of potential users. Using a computer today requires a person to have rudimentary capabilities with keyboards and the mouse. Wouldn’t it be great if all they needed was hand gestures? Although not mentioned it would also be nice if computers responded intelligently to a user’s voice. There is absolutely no argument with the fact that user interaction with these machines is going to change over time. My personal prediction is that it will take years for much of what Craig discusses to come to a cost effective reality but it is certainly coming. I just don’t believe that what Craig discusses will be the future look of a Window 8.

• How to detect and configure an output with xrandr?

  - by ysap

  I have a DELL U2410 monitor connected to a Compaq 100B desktop equipped with an integrated AMD/ATI graphics card (AMD E-350). The installed O/S is Ubuntu 10.04 LTS. The computer is connected to the monitor via the DVI connection. The problem is that I cannot set the desktop resolution to the native 1920x1200. The maximum allowed resolution is 1600x1200. Doing some research I found about the xrandr utility. Unfortunately, when trying to use it I cannot configure it to the required resolution. First, it does not report the output name (which supposed to be DVI-0), saying default instead. Without it I cannot use the --fb option. The EDID utility seems to identify the monitor well. Here's the output from get-edid: # EDID version 1 revision 3 Section "Monitor" # Block type: 2:0 3:ff # Block type: 2:0 3:fc Identifier "DELL U2410" VendorName "DEL" ModelName "DELL U2410" # Block type: 2:0 3:ff # Block type: 2:0 3:fc # Block type: 2:0 3:fd HorizSync 30-81 VertRefresh 56-76 # Max dot clock (video bandwidth) 170 MHz # DPMS capabilities: Active off:yes Suspend:yes Standby:yes Mode "1920x1200" # vfreq 59.950Hz, hfreq 74.038kHz DotClock 154.000000 HTimings 1920 1968 2000 2080 VTimings 1200 1203 1209 1235 Flags "-HSync" "+VSync" EndMode # Block type: 2:0 3:ff # Block type: 2:0 3:fc # Block type: 2:0 3:fd EndSection but the xrandr -q command returns: Screen 0: minimum 640 x 400, current 1600 x 1200, maximum 1600 x 1200 default connected 1600x1200+0+0 0mm x 0mm 1600x1200 0.0* 1280x1024 0.0 1152x864 0.0 1024x768 0.0 800x600 0.0 640x480 0.0 720x400 0.0 When I try to set the resolution, I get: $ xrandr --fb 1920x1200 xrandr: screen cannot be larger than 1600x1200 (desired size 1920x1200) $ xrandr --output DVI-0 --auto warning: output DVI-0 not found; ignoring How can I set the screen resolution to 1920x1200? Why doesn't xrandr identify the DVI-0 output? Note that the same computer running Ubuntu version higher than 10.04 detects the correct resolution with no problems. On this machine I cannot upgrade due to some legacy hardware compatibility problems. Also, I don't see any optional screen drivers available in the Hardware Drivers dialog. ---- UPDATE: following the answer to this question, I got some advance. Now the required mode is listed in the xrandr -q list, but I can't switch to that mode. Using the Monitors applet (which now shows the new mode), I get the response that: The selected configuration for displays could not be applied. Could not set the configuration to CRTC 262.

• xrandr shows two displays (LVDS1), but how can I use VGA1 only?

  - by Tom Fishman

  We're running Ubuntu 11 on this hardware: Foxconn R20-D2 Intel Atom D510 Intel NM10 Intel GMA 3150 Barebone There is no integrated display (it is a barebone box). I connected an external VGA to it. However xrandr shows two displays: Screen 0: minimum 320 x 200, current 1024 x 768, maximum 4096 x 4096 LVDS1 connected 1024x768+0+0 (normal left inverted right x axis y axis) 0mm x 0mm 1024x768 60.0*+ 800x600 60.3 56.2 640x480 59.9 VGA1 connected 1024x768+0+0 (normal left inverted right x axis y axis) 519mm x 324mm 1920x1200 60.0 + 1600x1200 60.0 1680x1050 60.0 1280x1024 76.0 75.0 72.0 60.0 1440x900 75.0 59.9 1152x864 75.0 1024x768 75.1 70.1 60.0* 832x624 74.6 800x600 72.2 75.0 60.3 640x480 72.8 75.0 66.7 60.0 720x400 70.1 But I don't have two displays. How can I get rid of LVDS1 and use only VGA1? The direct result is that I'm seeing a 1024x768 resolution on my VGA display, because the OS is using "mirror" mode which uses the lower resolution of the two. Turning off the mirror is not a solution. I want to fix it. Related logs: ...

• Welcome 2011

  - by WeigeltRo

  Things that happened in 2010 MIX10 was absolutely fantastic. Read my report of MIX10 to see why.   The dotnet Cologne 2010, the community conference organized by the .NET user group Köln and my own group Bonn-to-Code.Net became an even bigger success than I dared to dream of.   There was a huge discrepancy between the efforts by Microsoft to support .NET user groups to organize public live streaming events of the PDC keynote (the dotnet Cologne team joined forces with netug  Niederrhein to organize the PDCologne) and the actual content of the keynote. The reaction of the audience at our event was “meh” and even worse I seriously doubt we’ll ever get that number of people to such an event (which on top of that suffered from technical difficulties beyond our control).   What definitely would have deserved the public live streaming event treatment was the Silverlight Firestarter (aka “Silverlight Damage Control”) event. And maybe we would have thought about organizing something if it weren’t for the “burned earth” left by the PDC keynote. Anyway, the stuff shown at the firestarter keynote was the topic of conversations among colleagues days later (“did you see that? oh yeah, that was seriously cool”). Things that I have learned/observed/noticed in 2010 In the long run, there’s a huge difference between “It works pretty well” and “it just works and I never have to think about it”. I had to get rid of my USB graphics adapter powering the third monitor (read about it in this blog post). Various small issues (desktop icons sometimes moving their positions after a reboot for no apparent reasons, at least one game I couldn’t get run at all, all three monitors sometimes simply refusing to wake up after standby) finally made me buy a PCIe 1x graphics adapter. If you’re interested: The combination of a NVIDIA GTX 460 and a GT 220 is running in “don’t make me think” mode for a couple of months now.   PowerPoint 2010 is a seriously cool piece of software. Not only the new hardware-accelerated effects, but also features like built-in background removal and picture processing (which in many cases are simply “good enough” and save a lot of time) or the smart guides.   Outlook 2010 crashes on me a lot. I haven’t been successful in reproducing these crashes, they just happen when every couple of days on different occasions (only thing in common: I clicked something in the main window – yeah, very helpful observation)   Visual Studio 2010 reminds me of Visual Studio 2005 before SP1, which is actually not a good thing to say about a piece of software. I think it’s telling that Microsoft’s message regarding the beta of SP1 has been different from earlier service pack betas (promising an upgrade path for a beta to the RTM sounds to me like “please, please use it NOW!”).   I have a love/hate relationship with ReSharper. I don’t want to develop without it, but at the same time I can’t fail to notice that ReSharper is taking a heavy toll in terms of performance and sometimes stability. Things I’m looking forward to in 2011 Obviously, the dotnet Cologne 2011. We already have been able to score some big name sponsors (Microsoft, Intel), but we’re still looking for more sponsors. And be assured that we’ll make sure that our partners get the most out of their contribution, regardless of how big or small.   MIX11, period.    Silverlight 5 is going to be great. The only thing I’m a bit nervous about is that I still haven’t read anything official on whether C# next version’s async/await will be in it. Leaving that out would be really stupid considering the end-of-2011 release of SL5 (moving the next release way into the future).

• 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.

• Expanding the Partner Ecosystem with Third-Party Plug-ins

  - by Joe Diemer

  Oracle Enterprise Manager’s extensibility capabilities are designed to allow customers and partners to adapt Enterprise Manager for management of heterogeneous environments with Plug-ins and Connectors.  Third-party developers continue to take advantage of Oracle Enterprise Manager’s Extensibility Development Kit (EDK) to build plug-ins to Enterprise Manager 12c, such as F5’s BIG IP Plug-in and Entuity’s Eye of the Storm Network Management Plug-In.  Partners can also validate their plug-ins through the Oracle Validated Integration (OVI) program, which assures customers that the plug-in has been tested and is functionally and technically sound, is designed in a reliable and standardized manner, and operates and performs as documented.   Two very recent examples of partners which have beta versions of their plug-ins are Blue Medora's VMware vSphere plug-in and the NetApp Storage plug-in.  VMware vSphere Plug-in by Blue Medora Blue Medora, an Oracle Partner Network (OPN) “Gold” member, which just announced that it is now signing up customers to try a beta version of their new VMware vSphere plug-in for Enterprise Manager 12c.  According to Blue Medora, the vSphere plug-in monitors critical VMware metrics (CPU, Memory, Disk, Network, etc) at the Host, VM, Cluster and Resource Pool levels.  It has minimal performance impact via an “agentless” approach that requires no installation directly on VMware servers.  It has discovery capabilities for VMware Datacenters, ESX Hosts, Clusters, Virtual Machines, and Datastores.  It offers integration of native VMware Events into Enterprise Manager, and it provides over 300 VMware-related health, availability, performance, and configuration metrics.  It comes with more than 30 out-of-the-box pre-defined thresholds and can manage VMware via a series of jobs split between cluster, host and VM target types.The company reports that the Enterprise Manager 12c plug-in supports vSphere versions 4.0, 4.5 and 5.0.  Platforms supported include Linux 64-bit, Windows, AIX and Solaris SPARC and x86.  Information about the plug-in, including how to sign up for the beta, is available at their web site at http://bluemedora.com after selecting the "Products" tab. NetApp Storage Plug-in NetApp believes the combination of storage system monitoring with comprehensive management of Oracle systems with Enterprise Manager will help customers reduce the cost and complexity of managing applications that rely on NetApp storage and Oracle technologies.  So, NetApp built a plug-in and reports that it has comprehensive availability and performance information for NetApp storage systems.  Using the plug-in, Oracle Enterprise Manager customers with NetApp storage solutions can track the association between databases and storage components and thereby respond to faults and IO performance bottlenecks quickly. With the latest configuration management capabilities, one can also perform drift analysis to make sure all storage systems are configured as per established gold standards. The company is also now signing up beta customers, which can be done at the NetApp Communities site at https://communities.netapp.com/groups/netapp-storage-system-plug-in-for-oem12c-beta. Learn More about Enterprise Manager Extensibility More plug-ins from other partners are soon to come, which I'll be reporting on them here.  To learn more about Enterprise Manager and how customers and partners can build plug-ins using the EDK to manage a multi-vendor data center, go to http://oracle.com/enterprisemanager in the Heterogeneous Management solution area.  The site also lists the plug-ins available with information on how to obtain them.  More info about the Oracle Validated Integration program can be found at the OPN Enterprise Manager Knowledge Zone in the "Develop" tab.

• Tuning Default WorkManager - Advantages and Disadvantages

  - by Murali Veligeti

  Before discussing on Tuning Default WorkManager, lets have a brief introduction on What is Default WorkManger Before Weblogic Server 9.0 release, we had the concept of Execute Queues. WebLogic Server (before WLS 9.0), processing was performed in multiple execute queues. Different classes of work were executed in different queues, based on priority and ordering requirements, and to avoid deadlocks. In addition to the default execute queue, weblogic.kernel.default, there were pre-configured queues dedicated to internal administrative traffic, such as weblogic.admin.HTTP and weblogic.admin.RMI.Users could control thread usage by altering the number of threads in the default queue, or configure custom execute queues to ensure that particular applications had access to a fixed number of execute threads, regardless of overall system load. From WLS 9.0 release onwards WebLogic Server uses is a single thread pool (single thread pool which is called Default WorkManager), in which all types of work are executed. WebLogic Server prioritizes work based on rules you define, and run-time metrics, including the actual time it takes to execute a request and the rate at which requests are entering and leaving the pool.The common thread pool changes its size automatically to maximize throughput. The queue monitors throughput over time and based on history, determines whether to adjust the thread count. For example, if historical throughput statistics indicate that a higher thread count increased throughput, WebLogic increases the thread count. Similarly, if statistics indicate that fewer threads did not reduce throughput, WebLogic decreases the thread count. This new strategy makes it easier for administrators to allocate processing resources and manage performance, avoiding the effort and complexity involved in configuring, monitoring, and tuning custom executes queues. The Default WorkManager is used to handle thread management and perform self-tuning.This Work Manager is used by an application when no other Work Managers are specified in the application’s deployment descriptors. In many situations, the default Work Manager may be sufficient for most application requirements. WebLogic Server’s thread-handling algorithms assign each application its own fair share by default. Applications are given equal priority for threads and are prevented from monopolizing them. The default work-manager, as its name tells, is the work-manager defined by default.Thus, all applications deployed on WLS will use it. But sometimes, when your application is already in production, it's obvious you can't take your EAR / WAR, update the deployment descriptor(s) and redeploy it.The default work-manager belongs to a thread-pool, as initial thread-pool comes with only five threads, that's not much. If your application has to face a large number of hits, you may want to start with more than that.Well, that's quite easy. You have  two option to do so.1) Modify the config.xmlJust add the following line(s) in your server definition : <server> <name>AdminServer</name> <self-tuning-thread-pool-size-min>100</self-tuning-thread-pool-size-min> <self-tuning-thread-pool-size-max>200</self-tuning-thread-pool-size-max> [...] </server> 2) Adding some JVM parameters Add the following system property in setDomainEnv.sh/setDomainEnv.cmd or startWebLogic.sh/startWebLogic.cmd : -Dweblogic.threadpool.MinPoolSize=100 -Dweblogic.threadpool.MaxPoolSize=100 Reboot WLS and see the option has been taken into account . Disadvantage: So far its fine. But here there is an disadvantage in tuning Default WorkManager. Internally Weblogic Server has many work managers configured for different types of work.  if we run out of threads in the self-tuning pool(because of system property -Dweblogic.threadpool.MaxPoolSize) due to being undersized, then important work that WLS might need to do could be starved.  So, while limiting the self-tuning would limit the default WorkManager and internally it also limits all other internal WorkManagers which WLS uses.So the best alternative is to override the default WorkManager that means creating a WorkManager for the Application and assign the WorkManager for the application instead of tuning the Default WorkManager.

• Guest blog: A Closer Look at Oracle Price Analytics by Will Hutchinson

  - by Takin Babaei

  Overview:  Price Analytics helps companies understand how much of each sale goes into discounts, special terms, and allowances. This visibility lets sales management see the panoply of discounts and start seeing whether each discount drives desired behavior. In Price Analytics monitors parts of the quote-to-order process, tracking quotes, including the whole price waterfall and seeing which result in orders. The “price waterfall” shows all discounts between list price and “pocket price”. Pocket price is the final price the vendor puts in its pocket after all discounts are taken. The value proposition: Based on benchmarks from leading consultancies and companies I have talked to, where they have studied the effects of discounting and started enforcing what many of them call “discount discipline”, they find they can increase the pocket price by 0.8-3%. Yes, in today’s zero or negative inflation environment, one can, through better monitoring of discounts, collect what amounts to a price rise of a few percent. We are not talking about selling more product, merely about collecting a higher pocket price without decreasing quantities sold. Higher prices fall straight to the bottom line. The best reference I have ever found for understanding this phenomenon comes from an article from the September-October 1992 issue of Harvard Business Review called “Managing Price, Gaining Profit” by Michael Marn and Robert Rosiello of McKinsey & Co. They describe the outsized impact price management has on bottom line performance compared to selling more product or cutting variable or fixed costs. Price Analytics manages what Marn and Rosiello call “transaction pricing”, namely the prices of a given transaction, as opposed to what is on the price list or pricing according to the value received. They make the point that if the vendor does not manage the price waterfall, customers will, to the vendor’s detriment. It also discusses its findings that in companies it studied, there was no correlation between discount levels and any indication of customer value. I urge you to read this article. What Price Analytics does: Price analytics looks at quotes the company issues and tracks them until either the quote is accepted or rejected or it expires. There are prebuilt adapters for EBS and Siebel as well as a universal adapter. The target audience includes pricing analysts, product managers, sales managers, and VP’s of sales, marketing, finance, and sales operations. It tracks how effective discounts have been, the win rate on quotes, how well pricing policies have been followed, customer and product profitability, and customer performance against commitments. It has the concept of price waterfall, the deal lifecycle, and price segmentation built into the product. These help product and sales managers understand their pricing and its effectiveness on driving revenue and profit. They also help understand how terms are adhered to during negotiations. They also help people understand what segments exist and how well they are adhered to. To help your company increase its profits and revenues, I urge you to look at this product.

• Application Does Not Start in Windows 7

  - by Jim Fell

  I recently installed a new 60GB SSD as my primary hard drive and re-installed Windows 7 Professional 64-bit. I then installed SSD Fresh from Abelssoft to optimize Windows to run on the SSD. It seemed to install okay, but when I try to run the utility, its splash screen appears briefly before it quietly closes. No errors are displayed; the utility just fails to launch. I have run SSD Fresh on another SSD-equipped Windows 7 Pro x64 computer in the past without any problems. Does anyone know what might be preventing the program from running? I tried running sfc /scannow from the command line (with administrator privileges), shutting down the Spybot Resident, and disabling the firewall and virus scanner. I also tried running the tool as administrator; I even tried reinstalling it, running the installer as administrator. No luck. Every time I try to launch the program the Event Viewer logs this same set of errors: Error 4/2/2012 11:35:44 PM Application Error 1000 (100) Faulting application name: SSDFresh.exe, version: 1.0.0.0, time stamp: 0x4f2a45d8 Faulting module name: unknown, version: 0.0.0.0, time stamp: 0x00000000 Exception code: 0xc0000005 Fault offset: 0x000007ff0016dbba Faulting process id: 0x994 Faulting application start time: 0x01cd11fd9fe978df Faulting application path: C:\Program Files (x86)\SSD Fresh\SSDFresh.exe Faulting module path: unknown Report Id: dfeed551-7df0-11e1-a2c7-002522c47ec0 Error 4/2/2012 11:35:43 PM .NET Runtime 1026 None Application: SSDFresh.exe Framework Version: v4.0.30319 Description: The process was terminated due to an unhandled exception.

• A story of Murphy&ndash;my technical issues at TechDays Switzerland #chtd

  - by Laurent Bugnion

  I had two sessions at the recent Swiss TechDays. While the first one (Advanced Development for Windows Phone 8) went extremely well (I think), I had a very annoying technical issue in the beginning of my second session. First let me add that I talked to Microsoft about that and I hope they will change a few things in the room assignment for next year. My two sessions were one right after the other, with only 15 minutes break to change room. I don’t mind having two sessions so close from each other, but I would really like them to be in the same room in order to avoid having to move my laptops (plural, that will become important later) and redoing the tech check. That being said, I am guilty of not checking where my talks would be before the day before the conference, and when I did notice, it was too late to change it. After my first session, I quickly moved to the other room and setup my main laptop, a Dell Precision. We tested the video output (VGA) and didn’t notice anything special. The projectors are using a fairly high resolution (kudos to the Basel conference center for not having old school 1024x768 projectors anymore, that makes Blend really hard to demo ;) but since everything went great during the first talk, I was not worried. In fact I even had some time to chat with some early attendees about my Microsoft Surface and the Samsung Slate 7, which I had carried with me in addition to the Precision. I just thought it would be nice to show the hardware that Windows 8 can run on, without thinking any further. When the session started, I immediately noticed that the main screen was not showing anything. I thought I had just forgotten to switch to “duplicate” for the video output, and did that with a quick Win-P. However it didn’t “hold”. After 2 seconds, it reverted back to a black display for my attendees. Then I started to really worry. We tried everything, switching from VGA to HDMI, changing the resolution, setting the projector as primary display, but nothing did the trick. The projector was just refusing to show my screen. Now, to show you how despaired I started to be, I even considered using the “extend” setting (which worked just fine), and to use one of the feedback monitors on the floor but really it was super cumbersome. Eventually, my last resort arrived: I started my Samsung Slate 7, which by chance has Visual Studio 12 and Blend 5 installed, plugged the HDMI projector in the dock (yes, I had the dock with me, which I usually don’t!), connected it to internet (had to enter a long password for that), loaded the source code from my main machine using a USB stick and…. finally started to give my presentation. All in all I think we lost about 10 minutes. Amongst the most horrible minutes of my whole life, truly (yes I am blessed, I didn’t have that many horrible minutes in my life ;) I really want to apologize to my attendees. We joked a bit during the attempts to resolve the issue, the reactions I had after the session were all very nice and sympathetic. Only a handful of people left my session while I was having the issues, and I really don’t blame them (who knew how long the problem would last!!). But still, I probably talked at more than 60 sessions over the years, and this was by far my most painful moment. What did I learn? So what did I learn from this? Well from now on I will always have my slate ready with the latest source code, internet connection and every tool I might need during the presentation. This way, if I detect even a hint that the Precision might not work, I will just switch to the Slate. The experience of presenting on the slate is actually not bad at all, it is just a bit slow for my taste, but it does work. By the way, I will be posting the code and slides for my sessions very soon, I just need to “clean it and zip it”. Stay tuned, and thanks again for your patience in that horrible circumstance.

• Intermittent lockups, unable to diagnose in over a year

  - by Magsol

  Here's a real doosie; I may just give my firstborn child to whomever helps me solve this problem. In July 2008, I assembled what would be my desktop computer for graduate school. Here are the specs of the machine I built: Thermaltake 750W PSU Corsair Dominator 2x2GB 240-pin SDRAM Thermaltake Tower Asus P5K Deluxe Motherboard Intel Core 2 Quad Q9300 2.5GHz CPU 2 x GeForce 8600 GT WD Caviar Blue 640GB hard drive CD burner DVD burner Soon thereafter, I ordered a new motherboard (because I was an idiot; that first motherboard supported CrossFire, not SLI), an Asus P5N-D. I was originally running Windows XP SP3. Pretty much right into the start of the fall semester, my desktop would simply lock up after awhile. If my system was largely idling, it would be after 1-3 days. If was gaming, it often happened an hour or two into my gaming session, indicating a link to activity level. Here's where it started getting interesting. I started looking at the system temps. The CPU was warmer than it should have been (~60s C), so I purchased some more efficient cooling compound a way better cooler for it. Now it hardly goes over 40 C. Intel was even kind enough to swap it out for free, just to rule it out. Lockups continued. The graphics cards were also running pretty warm: about 60 C idling. Removing one of them seemed to improve stability a little bit...as in, it wouldn't lock up quite as frequently, but still always eventually locked up. But it didn't matter which card I used or removed, the lockups continued. I reverted back to the original motherboard, the P5K Deluxe. Lockups continued. I purchased an entirely new motherboard, eVGA's nForce 750i. Lockups continued. Ran memtest86+ over and over and over, with no errors. Even RMA'd the memory. Lockups continued. Replaced the PSU with a Corsair 750W PSU. Lockups continued. Tried disconnecting all IDE drives (HDDs are SATA). Lockups continued. Replaced both graphics cards with a single Radeon HD 4980. Average temps are now always around 50 C when idling, 60 C only when gaming. Lockups continued. Throughout the whole ordeal, the system has been upgraded from Windows XP SP3 to Vista 32-bit, to Vista 64-bit, and is now at Windows 7 64-bit. Lockups have occurred at every step along the way (each OS was in place for at least a few months before the next upgrade). Edit: By "upgrade" I mean clean install each time. In addition to those reformats, I have performed many, many other reformats of the system and a reinstall of whatever OS had been previously installed in an attempt to rectify this problem, to no avail./Edit When the system locks up, there's no blue screen, no reboot, no error message of any kind. It simply freezes in place until I hit the reset button. Very, very rarely, once Windows boots back up, the system informs me that Windows has recovered from an error, but it can never find the source aside from some piece of hardware. I've swapped out every component in this computer, and there are more fans in it than I care to count...though for the sake of completeness: top 80mm case fan (out) rear 80mm case fan (out) rear 120mm case fan (out) front 120mm case fan (in) side 250mm case fan (in) giant CPU fan on-board motherboard fan (the eVGA board) triple-fan memory setup (came with the memory) PSU internal fan another 120mm fan I stuck on the underside of the video card to keep hot air from collecting at the bottom of the case I'm truly out of ideas. ANY help at all would be oh-so-very GREATLY appreciated. Thank you!

• Simple OpenGL program major slow down at high resolution

  - by Grieverheart

  I have created a small OpenGL 3.3 (Core) program using freeglut. The whole geometry is two boxes and one plane with some textures. I can move around like in an FPS and that's it. The problem is I face a big slow down of fps when I make my window large (i.e. above 1920x1080). I have monitors GPU usage when in full-screen and it shows GPU load of nearly 100% and Memory Controller load of ~85%. When at 600x600, these numbers are at about 45%, my CPU is also at full load. I use deferred rendering at the moment but even when forward rendering, the slow down was nearly as severe. I can't imagine my GPU is not powerful enough for something this simple when I play many games at 1080p (I have a GeForce GT 120M btw). Below are my shaders, First Pass #VS #version 330 core uniform mat4 ModelViewMatrix; uniform mat3 NormalMatrix; uniform mat4 MVPMatrix; uniform float scale; layout(location = 0) in vec3 in_Position; layout(location = 1) in vec3 in_Normal; layout(location = 2) in vec2 in_TexCoord; smooth out vec3 pass_Normal; smooth out vec3 pass_Position; smooth out vec2 TexCoord; void main(void){ pass_Position = (ModelViewMatrix * vec4(scale * in_Position, 1.0)).xyz; pass_Normal = NormalMatrix * in_Normal; TexCoord = in_TexCoord; gl_Position = MVPMatrix * vec4(scale * in_Position, 1.0); } #FS #version 330 core uniform sampler2D inSampler; smooth in vec3 pass_Normal; smooth in vec3 pass_Position; smooth in vec2 TexCoord; layout(location = 0) out vec3 outPosition; layout(location = 1) out vec3 outDiffuse; layout(location = 2) out vec3 outNormal; void main(void){ outPosition = pass_Position; outDiffuse = texture(inSampler, TexCoord).xyz; outNormal = pass_Normal; } Second Pass #VS #version 330 core uniform float scale; layout(location = 0) in vec3 in_Position; void main(void){ gl_Position = mat4(1.0) * vec4(scale * in_Position, 1.0); } #FS #version 330 core struct Light{ vec3 direction; }; uniform ivec2 ScreenSize; uniform Light light; uniform sampler2D PositionMap; uniform sampler2D ColorMap; uniform sampler2D NormalMap; out vec4 out_Color; vec2 CalcTexCoord(void){ return gl_FragCoord.xy / ScreenSize; } vec4 CalcLight(vec3 position, vec3 normal){ vec4 DiffuseColor = vec4(0.0); vec4 SpecularColor = vec4(0.0); vec3 light_Direction = -normalize(light.direction); float diffuse = max(0.0, dot(normal, light_Direction)); if(diffuse 0.0){ DiffuseColor = diffuse * vec4(1.0); vec3 camera_Direction = normalize(-position); vec3 half_vector = normalize(camera_Direction + light_Direction); float specular = max(0.0, dot(normal, half_vector)); float fspecular = pow(specular, 128.0); SpecularColor = fspecular * vec4(1.0); } return DiffuseColor + SpecularColor + vec4(0.1); } void main(void){ vec2 TexCoord = CalcTexCoord(); vec3 Position = texture(PositionMap, TexCoord).xyz; vec3 Color = texture(ColorMap, TexCoord).xyz; vec3 Normal = normalize(texture(NormalMap, TexCoord).xyz); out_Color = vec4(Color, 1.0) * CalcLight(Position, Normal); } Is it normal for the GPU to be used that much under the described circumstances? Is it due to poor performance of freeglut? I understand that the problem could be specific to my code, but I can't paste the whole code here, if you need more info, please tell me.

• Screen Aspect Ratio

  - by Bill Evjen

  Jeffrey Dean, Pixar Aspect Ratio is very important to home video. What is aspect ratio – the ratio from the height to the width 2.35:1 The image is 2.35 times wide as it is high Pixar uses this for half of our movies This is called a widescreen image When modified to fit your television screen They cut this to fit the box of your screen When a comparison is made huge chunks of picture is missing It is harder to find what is going on when these pieces are missing The whole is greater than the pieces themselves. If you are missing pieces – you are missing the movie The soul and the mood is in the film shots. Cutting it to fit a screen, you are losing 30% of the movie Why different aspect ratios? Film before the 1950s 1.33:1 Academy Standard There were all aspects of images though. There was no standard. Thomas Edison developed projecting images onto a wall/screen He didn’t patent it as he saw no value in it. Then 1.37:1 came about to add a strip of sound This is the same size as a 35mm film Around 1952 – TV comes along NTSC Television followed the Academy Standard (4x3) Once TV came out, movie theater attendance plummets So Film brought forth color to combat this. Also early 3D Also Widescreen was brought forth. Cinema-Scope Studios at the time made movies bigger and bigger There was a Napoleon movie that was actually 4x1 … really wide. 1.85:1 Academy Flat 2.35:1 Anamorphic Scope (aka Panavision/Cinemascope) Almost all movies are made in these two aspect ratios Pixar has done half in one and half in the other Why choose one over the other? Artist choice It is part of the story the director wants to tell Can we preserve the story outside of the theaters? TVs before 1998 – they were very square Now TVs are very wide Historical options Toy Story released as it was and people cut it in a way that wasn’t liked by the studio Pan and Scan is another option Cut and then scan left or right depending on where the action is Frame Height Pixar can go back and animate more picture to account for the bottom/top bars. You end up with more sky and more ground The characters seem to get lost in the picture You lose what the director original intended Re-staging For animated movies, you can move characters around – restage the scene. It is a new completely different version of the film This is the best possible option that Pixar came up with They have stopped doing this really as the demand as pretty much dropped off Why not 1.33 today? There has been an evolution of taste and demands. VHS is a linear item The focus is about portability and not about quality Most was pan and scan and the quality was so bad – but people didn’t notice DVD was introduced in 1996 You could have more content – two versions of the film You could have the widescreen version and the 1.33 version People realized that they are seeing more of the movie with the widescreen High Def Televisions (16x9 monitors) This was introduced in 2005 Blu-ray Disc was introduced in 2006 This is all widescreen You cannot find a square TV anymore TVs are roughly 1.85:1 aspect ratio There is a change in demand Users are used to black bars and are used to widescreen Users are educated now What’s next for in-flight entertainment?

• What would cause Memcached to Hang for 2+ seconds?

  - by Brad Dwyer

  I'm going nuts trying to scale memcached. From their site: Memcached operations are almost all O(1). Connecting to it and issuing a get or stat command should never lag. If connecting lags, you may be hitting the max connections limit. See ServerMaint for details on stats to monitor. If issuing commands lags, you can have a number of tuning problems. Most common are hardware problems, not enough RAM (swapping), network problems (bandwidth, dropped packets, half-duplex connections). On rare occasion OS bugs or memcached bugs can contribute. Well.. it is most certainly not performing like an O(1) operation for me. Under low to normal load on our site memcached response times for get and set ops are about 0.001 seconds. Not bad. But if we triple the load we get outliers that take 100x (or in rare cases 1000x!) that long. I even had one instance where it took 2.2442 seconds for memcached to store a value. Obviously this is killing our site. Here's the output of Memcached-getStats during one of the slow periods: [pid] => 18079 [uptime] => 8903 [threads] => 4 [time] => 1332795759 [pointer_size] => 32 [rusage_user_seconds] => 26 [rusage_user_microseconds] => 503872 [rusage_system_seconds] => 125 [rusage_system_microseconds] => 477008 [curr_items] => 42099 [total_items] => 422500 [limit_maxbytes] => 943718400 [curr_connections] => 84 [total_connections] => 4946 [connection_structures] => 178 [bytes] => 7259957 [cmd_get] => 1679091 [cmd_set] => 351809 [get_hits] => 1662048 [get_misses] => 17043 [evictions] => 0 [bytes_read] => 109388476 [bytes_written] => 3187646458 [version] => 1.4.13 So things that I have ruled out so far are: Hitting the max connections limit (curr_connections of 84 is well below the default of max of 1024) Swapping - the machine has 900M out of 1024M of memory dedicated to memcached on a dedicated machine. It only appears to be using about 7MB of data as per the bytes stat. How would I diagnose the other hardware problems? prstat doesn't really show a whole lot going on in terms of CPU or memory usage. Not sure how to figure out the network problems but as this is a dedicated server on the same private network as the web box I don't think it's a connectivity issue (ping is less than a millisecond between the boxes). Is there something else I'm missing here? It's driving me nuts. Edit: Also forgot to mention that I've tried both persistent and non-persistent connections with minimal-to-no impact.

• Find/Replace Paragraph End (^13) in Microsoft Word 2007 Merges Paragraphs

  - by Mike Blyth

  I need to replace a target at the beginning of lines with something else. Without wildcards, I can say to replace "^pTarget" with "^pReplacement". With wildcards enabled, I use replace "^13Target" with "^13Replacement". The replacement is successful except that the paragraph is now merged with the previous one in a strange way: The end-paragraph mark is still in place and the paragraph begins on a new line, but Triple clicking to select paragraph selects both the changed paragraph and the one above In a macro, starting in the paragraph above and extending the selection to the end of paragraph causes both paragraphs to be selected. Inter-paragraph spacing disappears between the changed paragraph and the one above. In essence, the paragraph boundary has been removed although the end-paragraph mark is still shown. To duplicate this problem, make a new document Line 1 Line 2 Line 3 (separate paragraphs). Find and replace (with wildcards on) "^13" with "^13". If your result is the same as mine, you will see the problems listed above. I can work around this in the usual way of replacing ^p with something else first, e.g. "^p" = "$", then "$target" = "$replacement", but I'm curious about what's going on. (This is using Word 2007 on Windows 7) I don't know Word XML, but the XML output seems to correspond with the above. Replacing ^13 with ^13 moves the paragraphs together in almost the same way as replacing end-paragraph with end-line (^p = ^l). Here is the relevant XML of the original "Line 1, Line 2, Line 3" in separate paragraphs: <w:p w:rsidR="00BB3032" w:rsidRDefault="00027252"> <w:r><w:t>Line 1</w:t></w:r> </w:p> <w:p w:rsidR="00027252" w:rsidRDefault="00027252"> <w:r><w:t>Line 2</w:t></w:r> </w:p> <w:p w:rsidR="00027252" w:rsidRDefault="00027252"> <w:r><w:t>Line 3</w:t></w:r> </w:p> Now after replacing ^13 with ^13: <w:p w:rsidR="00027252" w:rsidRDefault="00027252"> <w:r><w:t>Line 1</w:t></w:r> <w:r w:rsidR="00C57863"><w:cr/></w:r> <w:r><w:t>Line 2</w:t></w:r> <w:r w:rsidR="00C57863"><w:cr/></w:r> <w:r><w:t>Line 3</w:t></w:r> <w:r w:rsidR="00C57863"><w:cr/></w:r> </w:p> Now original after replacement of ^p with ^l (convert end-paragraph to end-line) <w:p w:rsidR="00027252" w:rsidRDefault="00027252"> <w:r><w:t>Line 1</w:t></w:r> <w:r w:rsidR="00AC7B51"><w:br/></w:r> <w:r><w:t>Line 2</w:t></w:r> <w:r w:rsidR="00AC7B51"><w:br/></w:r> <w:r><w:t>Line 3</w:t></w:r> <w:r w:rsidR="00AC7B51"><w:br/></w:r> </w:p>

• MySQL Enterprise Backup 3.8.2 has been released!

  - by Hema Sridharan

  MySQL Enterprise Backup v3.8.2, a maintenance release of online MySQL backup tool, is now available for download from My Oracle Support  (MOS) website as our latest GA release.  It will also be available via the Oracle Software Delivery Cloud in approximately 1-2 weeks. A brief summary of the changes in MySQL Enterprise Backup version 3.8.2 is given below.   A. Functionality Added or Changed:  MySQL Enterprise Backup has a new --on-disk-full command line option. mysqlbackup could hang when the disk became full, rather than detecting the low space condition. mysqlbackup now monitors disk space when running backup commands, and users can now specify the action to take at a disk-full condition with the --on-disk-full option. For more details, refer this page MySQL Enterprise Backup has a new progress report feature, which periodically outputs short progress indicators on its  operations to user-selected destinations (for example, stdout, stderr, a file, or other choices). For more details on progress report options, refer here   B. Bugs Fixed: When --innodb-file-per-table=ON, if a table was renamed and backup-to-image was in progress, apply-log would fail when being run on the backup. (Bug #16903973)   MySQL Server failed to start after a backup was restored if  there had been online DDL transactions on partitioned tables during the time of backup. (Bug #16924499)   apply-log failed if ALTER TABLE ... REORGANIZE PARTITION was applied to partitioned InnoDB tables during backup. (Bug #16721824, Bug #16903951)  apply-incremental-backup might fail with an assertion error if  the InnoDB tables being backed up were created in Barracuda format and with their KEY_BLOCK_SIZE  values  different from the innodb_page_size . This fix ensures that different KEY_BLOCK_SIZE  values are handled properly during incremental backup and apply-incremental-backup operations.  If a table was renamed following a full backup, a subsequent incremental backup could copy the .frm file with the new name, but not the associated .ibd file with the new name. After a  restore, the InnoDB data dictionary could be in an  inconsistent state. This issue primarily occurred if the table  was not changed between the full backup and the subsequent  incremental backup. Bug #16262690)  After a full backup, if a table was renamed and modified,  apply-incremental-backup would crash when run on the backup directory. (Bug #16262609) The value of the binary log position in backup_variables.txt  could be different from the output displayed during the   backup-and-apply-log operation. (This issue did not occur if  the backup and apply-log steps were done separately.) (Bug  #16195529) When using the --only-innodb-with-frm option, MySQL Enterprise Backup tried to create temporary files at unintended locations in the file system, which might cause a failure when, for example, the user had no write privilege for those locations.   This fix makes sure the paths for the temporary files are  correct. (Bug #14787324)  A backup process might hang when it ran into an LSN mismatch between a data file  and the redo log. This fix makes sure the process does not hang and it displays an error message showing the  name of the problematic data file (Bug #14791645) Please post your questions / comments about Backup in forums. Thanks, MEB Team

• How To Create Your Own x86 Operating System for Modern PC Computers

  - by mudge

  I'd like to create a new operating system for x86 PC computers. I'd like it to be 64-bit but possibly run as 32-bit as well. I have these kinds of questions: What kinds of things do you start working on first? Knowing where to start in writing your own operating system seems to me to be a tricky subject, so I am interested in your input. Generally how to go about making your own 32-bit/64-bit operating system, or good resources that mention useful information about going about writing your own operating system for x86 computers. I don't care how old sources are as long as they are still relevant and useful to what I am doing. I know that I will want it to have kernel drivers that access peripheral hardware directly. Where should I look for advice and documentation for programming and understanding the interface to peripheral hardware the operating system will communicate with? I will need to understand how the operating system will receive input and interact with keyboards, mice, computer monitors, hard drives, USB, etc. etc. This is probably the area I know least about. I have the Intel instruction set manuals and have been getting more familiar with assembly programming, so the CPU side of things is what I know the most about. At this point I'm thinking that I'd like to implement the Linux system calls within my operating system so that programs that run on Linux can run on my operating system. I want my operating system to use the ELF binary format. I wonder what obstacles I have to overcome to achieve this Linux compatibility. Are the main things implementing the system calls that Linux provides, and using the ELF format? What else? I am also interested in people's thoughts about why it might not be a good idea to make your own operating system, and why it is a good idea to make your own operating system. Thank you for any input.

• Is background tasks the solution for this problem?

  - by Trinca

  Hi. I need to develop an enterprise app that monitors the network traffic. Basically it detects if the user is in wi-fi or cellular data and save the amount of bytes was sent and received in a period of time. I saw an App at the AppStore that do exactly this job. Detecting wi-fi or cellular data is quite simple using the Reachability Sample provided by Apple. My problem is to keep monitoring the bytes sent and received while the app is in background. As it is an enterprise App, I used UIBackgroundModes "voip" to avoid the app to be terminated. I also installed the setKeepAliveTimeout method and I'm able to see the logs each 10 minutes, BUT only for 10 seconds after the method runs. I mean, setKeepAliveTimeout brings my App to run a Timer for 10 seconds each 1o minutes. I'm thinking wether or not a task in background is the best solution for my problem. I'll appreciate any comments. EDIT: Ok guys. Thats the perfect way to do it. First of all you must read this: http://www.christian-fries.de/blog/files/tag-ios.html I tried this and it works really fine. All we need to do is to create a second thread detached from the main one. This way we have a continuos threading running forever. You must see the GCD docs at Apple's website also. Second thing you should consider for an enterprise App is to set it up as a voip App, this way iOS will put your App running even after a reboot. It's a special behavior iOS has to keep voip Apps running. Thats it guys. I hope it can help you.

• BindAttribute, Exclude nested properties for complex types

  - by David Board

  I have a 'Stream' model: public class Stream { public int ID { get; set; } [Required] [StringLength(50, ErrorMessage = "Stream name cannot be longer than 50 characters.")] public string Name { get; set; } [Required] [DataType(DataType.Url)] public string URL { get; set; } [Required] [Display(Name="Service")] public int ServiceID { get; set; } public virtual Service Service { get; set; } public virtual ICollection<Event> Events { get; set; } public virtual ICollection<Monitor> Monitors { get; set; } public virtual ICollection<AlertRule> AlertRules { get; set; } } For the 'create' view for this model, I have made a view model to pass some additional information to the view: public class StreamCreateVM { public Stream Stream { get; set; } public SelectList ServicesList { get; set; } public int SelectedService { get; set; } } Here is my create post action: [HttpPost] [ValidateAntiForgeryToken] public ActionResult Create([Bind(Include="Stream, Stream.Name, Stream.ServiceID, SelectedService")] StreamCreateVM viewModel) { if (ModelState.IsValid) { db.Streams.Add(viewModel.Stream); db.SaveChanges(); return RedirectToAction("Index", "Service", new { id = viewModel.Stream.ServiceID }); } return View(viewModel); } Now, this all works, apart from the [Bind(Include="Stream, Stream.Name, Stream.ServiceID, SelectedService")] bit. I can't seem to Include or Exclude properties within a nested object.

• Are web-safe colors still relevant?

  - by Gavin Miller

  Since the vast majority of monitors are 16-bit color or more, including mobile devices, does it make sense to even consider web-safe colors when choosing color schemes? Or is it something that ought to be relegated to history as a piece of trivia? For those of you that don't know what web-safe colors are: Another set of 216 color values is commonly considered to be the "web-safe" color palette, developed at a time when many computer displays were only capable of displaying 256 colors. A set of colors was needed that could be shown without dithering on 256-color displays; the number 216 was chosen partly because computer operating systems customarily reserved sixteen to twenty colors for their own use; it was also selected because it allows exactly six shades each of red, green, and blue (6 × 6 × 6 = 216). The list of colors is often presented as if it has special properties that render them immune to dithering. In fact, on 256-color displays applications can set a palette of any selection of colors that they choose, dithering the rest. These colors were chosen specifically because they matched the palettes selected by the then leading browser applications. [Wikipedia]
