  • PowerPivot FILTER condition optimizations

    - by Marco Russo (SQLBI)
    In the comments of a recent post from Alberto Ferrari there was an interesting note about different performance related to the order of conditions in a FILTER call. I investigated about that and Jeffrey Wang has been so nice to give me some info about actual implementation that I can share on a blog post. First of all, an important disclaimer: PowerPivot is intended to make life easier, not requiring the user to think how to write the order of elements in a formula just to get better performance....(read more)

  • The SQL of Membership: Equivalence Classes & Cliques

    It is awkward to do 'Graph databases' in SQL to explore the sort of relationships and memberships in social networks because equivalence relations are classes (a set of sets) rather than sets. However one can explore graphs in SQL if the relationship has all three of the mathematical properties needed for an equivalence relationship.

  • TechEd 2014 Day 1

    - by John Paul Cook
    Today at TechEd 2014, many people had questions about the in-memory database features in SQL Server 2014. A common question is how an in-memory database is different from having a database on a SQL Server with an amount of ram far greater than the size of the database. In-memory or memory optimized tables have different data structures and are accessed differently using a latch free and lock free approach that greatly improves performance. This provides part of the performance improvement. The rest...(read more)

  • Is it recommended to apply the new said-great 200 line Linux kernel patch?

    - by takpar
    Hi, Nowadays I'm hearing a lot about the new ~200 line path to Linux kernel that is said makes sensible difference in performance. Now, do anyone has experience on applying this path on his Ubuntu kernel? I also saw an alternative way that claimed has a better result: wget http://launchpadlibrarian.net/59511828/cgroup_patch chmod +x cgroup_patch sudo ./cgroup_patch What do you think this is? Is this validated? I ask this question because I need more performance but I can't risk on stability.

  • Cannot establish maximum resolution on ASUS PB278Q

    - by dentuzhik
    I've recently bought brand new ASUS PB278Q monitor. When trying to connect to my laptop, everything works great, except that I can't get the native resolution of my monitor (2560x1440) working. The automatic is 1920x1080. My graphic card is Nvidia GeForce 320m. Here's output from lspci for it: ~$ lspci | grep VGA 02:00.0 VGA compatible controller: NVIDIA Corporation GT216M [GeForce GT 320M] (rev a2) and also xrandr: ~$ xrandr Screen 0: minimum 8 x 8, current 3286 x 1437, maximum 8192 x 8192 VGA-0 disconnected (normal left inverted right x axis y axis) LVDS-0 connected primary 1366x768+0+669 (normal left inverted right x axis y axis) 344mm x 193mm 1366x768 60.0*+ HDMI-0 connected 1920x1080+1366+0 (normal left inverted right x axis y axis) 600mm x 340mm 1920x1080 60.0*+ 59.9 50.0 30.0 25.0 24.0 60.0 50.0 1680x1050 60.0 1440x900 59.9 1280x1024 75.0 60.0 1280x960 60.0 1280x800 59.8 1280x720 60.0 59.9 50.0 1152x864 75.0 1024x768 75.0 70.1 60.0 800x600 75.0 72.2 60.3 56.2 720x576 50.0 720x480 59.9 640x480 75.0 59.9 59.9 480x576 50.0 480x480 59.9 I have proprietary drivers installed on my machine, here's the info about the monitor from nvidia-settings (Actually I don't have enough reputation to post images, so here's the text): Chip Location: Internal Signal: TDMS Connection link: Single Native resolution: 2560x1440 Refresh rate: 60.00 Hz The monitor is connected to laptop via HDMI cable, and honestly I have no idea what version it is, and what version is my HDMI output of my graphics card. I tried to find how I can figure it out on the web, but had no luck. Also my video card has only VGA and HDMI outs so I can't test neither DVI-D cable nor DisplayPort. So apparently, there's some problem over there. At least I want to know exactly what's going on. I've tried to see if it a linux-specific problem, but windows also gave me the same resolution by default. What I've already tried: Connect through VGA (stupid one, of course it gave me 1920x1080). Checked two HDMI cables (not sure if they're the same or not, as mentioned above). Played around with xrandr and adding custom modes. Didn't help. Surfed for the info a lot on the web, but couldn't get appropriate results. Actually xrandr gives me the following: ~$ cvt 2560 1440 60 # 2560x1440 59.96 Hz (CVT 3.69M9) hsync: 89.52 kHz; pclk: 312.25 MHz Modeline "2560x1440_60.00" 312.25 2560 2752 3024 3488 1440 1443 1448 1493 -hsync +vsync ~$ xrandr --newmode "2560x1440_60.00" 312.25 2560 2752 3024 3488 1440 1443 1448 1493 -hsync +vsync ~$ xrandr Screen 0: minimum 8 x 8, current 3286 x 1437, maximum 8192 x 8192 VGA-0 disconnected (normal left inverted right x axis y axis) LVDS-0 connected 1366x768+0+669 (normal left inverted right x axis y axis) 344mm x 193mm 1366x768 60.0*+ HDMI-0 connected primary 1920x1080+1366+0 (normal left inverted right x axis y axis) 600mm x 340mm 1920x1080 60.0*+ 59.9 50.0 30.0 25.0 24.0 60.0 50.0 1680x1050 60.0 1440x900 59.9 1280x1024 75.0 60.0 1280x960 60.0 1280x800 59.8 1280x720 60.0 59.9 50.0 1152x864 75.0 1024x768 75.0 70.1 60.0 800x600 75.0 72.2 60.3 56.2 720x576 50.0 720x480 59.9 640x480 75.0 59.9 59.9 480x576 50.0 480x480 59.9 2560x1440_60.00 (0x34f) 312.2MHz h: width 2560 start 2752 end 3024 total 3488 skew 0 clock 89.5KHz v: height 1440 start 1443 end 1448 total 1493 clock 60.0Hz ~$ xrandr --addmode HDMI-0 2560x1440_60.00 X Error of failed request: BadMatch (invalid parameter attributes) Major opcode of failed request: 140 (RANDR) Minor opcode of failed request: 18 (RRAddOutputMode) Serial number of failed request: 29 Current serial number in output stream: 30 What I intend to do next: Try another HDMI cable?

Any explanations why it isn't working are appreciated.

  • Are there any limitations to using WinRT instead of .Net?

    - by jerrykobes
    From my understanding creating an application that runs on multiple architectures requires virtualization, and virtualization reduces performance since it creates a layer of abstraction. With Windows 8 supporting both Intel and ARM architectures should we expect slower performance with a WinRT app versus a .Net app running on an Intel device? Also, will WinRT support database connectivity and active directory access?

  • How to make Stack.Pop threadsafe

    - by user260197
    I am using the BlockingQueue code posted in this question, but realized I needed to use a Stack instead of a Queue given how my program runs. I converted it to use a Stack and renamed the class as needed. For performance I removed locking in Push, since my producer code is single threaded. My problem is how can thread working on the (now) thread safe Stack know when it is empty. Even if I add another thread safe wrapper around Count that locks on the underlying collection like Push and Pop do, I still run into the race condition that access Count and then Pop are not atomic. Possible solutions as I see them (which is preferred and am I missing any that would work better?): Consumer threads catch the InvalidOperationException thrown by Pop(). Pop() return a nullptr when _stack-Count == 0, however C++-CLI does not have the default() operator ala C#. Pop() returns a boolean and uses an output parameter to return the popped element. Here is the code I am using right now: generic <typename T> public ref class ThreadSafeStack { public: ThreadSafeStack() { _stack = gcnew Collections::Generic::Stack<T>(); } public: void Push(T element) { _stack->Push(element); } T Pop(void) { System::Threading::Monitor::Enter(_stack); try { return _stack->Pop(); } finally { System::Threading::Monitor::Exit(_stack); } } public: property int Count { int get(void) { System::Threading::Monitor::Enter(_stack); try { return _stack->Count; } finally { System::Threading::Monitor::Exit(_stack); } } } private: Collections::Generic::Stack<T> ^_stack; };

  • Custom WPF TreeView

    I have a custom class that I would like to bind a WPF TreeView that has three tiers. Each tier needs to be bound like this: Monitor --> LCD --> Samsung 1445 LCD --> CRT --> Sony 125 CRT Here is the example code: public partial class MainWindow : Window { public MainWindow() { InitializeComponent(); SystemInventory sysInventory = new SystemInventory(); //Possibly do something like this. _myTreeView.DataContext = sysInventory.DeviceGroupInstances; } public class SystemInventory { public ObservableCollection<DeviceGroup> DeviceGroupInstances { get; set; } public SystemInventory() { DeviceGroupInstances = new ObservableCollection<DeviceGroup>(); DeviceGroupInstances.Add(new DeviceGroup("Monitor")); } } public class DeviceGroup { public string DeviceGroupName { get; set; } public ObservableCollection<DeviceType> DeviceTypeInstances { get; set; } public DeviceGroup(string deviceGroupName) { DeviceTypeInstances = new ObservableCollection<DeviceType>(); DeviceGroupName = deviceGroupName; if (deviceGroupName == "Monitor") { DeviceTypeInstances.Add(new DeviceType("LCD")); DeviceTypeInstances.Add(new DeviceType("CRT")); } } } public class DeviceType { public string DeviceTypeName { get; set; } public ObservableCollection<DeviceInstance> DeviceInstances { get; set; } public DeviceType(string deviceGroupName) { DeviceInstances = new ObservableCollection<DeviceInstance>(); DeviceTypeName = deviceGroupName; if (deviceGroupName == "Monitor") { DeviceInstances.Add(new DeviceInstance("Samsung 1445 LCD")); } else { DeviceInstances.Add(new DeviceInstance("Sony 125 CRT")); } } } public class DeviceInstance { public string DeviceInstanceName { get; set; } public DeviceInstance(string instanceName) { DeviceInstanceName = instanceName; } } }

  • A more elegant way to start a multithread alarm in Rebol VID ? (What's the equivalent of load event?

    - by Rebol Tutorial
    I want to trigger an alarm when the GUI starts. I can't see what's the equivalent of load event of other language in Rebol VID, so I put it in the periodic handler which is quite circumvoluted. So how to do this more cleanly ? alarm-data: none set-alarm: func [ "Set alarm for future time." seconds "Seconds from now to ring alarm." message [string! unset!] "Message to print on alarm." ] [ alarm-data: reduce [now/time + seconds message] ] ring: func [ "Action for when alarm comes due." message [string! unset!] ] [ set-face monitor either message [message]["RIIIING!"] ; Your sound playing can also go here (my computer doesn't have speakers). ] periodic: func [ "Called every second, checks alarms." fact action event ] [ either alarm-data [ ; Update alarm countdown. set-face monitor rejoin [ "Alarm will ring in " to integer! alarm-data/1 - now/time " seconds." ] ; Check alarm. if now/time > alarm-data/1 [ ring alarm-data/2 ;alarm-data: none ; Reset once fired. ] ][ either value?

  • C#, Can I check on a lock without trying to acquire it?

    - by Biff MaGriff
    Hello, I have a lock in my c# web app that prevents users from running the update script once it has started. I was thinking I would put a notification in my master page to let the user know that the data isn't all there yet. Currently I do my locking like so. protected void butRefreshData_Click(object sender, EventArgs e) { Thread t = new Thread(new ParameterizedThreadStart(UpdateDatabase)); t.Start(this); //sleep for a bit to ensure that javascript has a chance to get rendered Thread.Sleep(100); } public static void UpdateDatabase(object con) { if (Monitor.TryEnter(myLock)) { Updater.RepopulateDatabase(); Monitor.Exit(myLock); } else { Common.RegisterStartupScript(con, AlreadyLockedJavaScript); } } And I do not want to do if(Monitor.TryEnter(myLock)) Monitor.Exit(myLock); else //show processing labal As I imagine there is a slight possibility that it might display the notification when it isn't actually running. Is there an alternative I can use? Edit: Hi Everyone, thanks a lot for your suggestions! Unfortunately I couldn't quite get them to work... However I combined the ideas on 2 answers and came up with my own solution.
