• How do I get the brightness control working on a Lenovo Yoga 13?

  - by Viktor Ax

  Brightness control doesn't work by default in Ubuntu 13.04. Solution for 12.10 doesn't work, also as this Any idea how to fix it? Update: After research I found how to change brightness manually. What need to do is to type in terminal: echo 2000 | sudo tee /sys/class/backlight/intel_backlight/brightness It will reduce brightness by half, but still would be good to find solution which will allow to use keyboard for changing brightness. Update2: Found solution, see below

• Advanced Continuous Delivery to Azure from TFS, Part 1: Good Enough Is Not Great

  - by jasont

  The folks over on the TFS / Visual Studio team have been working hard at releasing a steady stream of new features for their new hosted Team Foundation Service in the cloud. One of the most significant features released was simple continuous delivery of your solution into your Azure deployments. The original announcement from Brian Harry can be found here. Team Foundation Service is a great platform for .Net developers who are used to working with TFS on-premises. I’ve been using it since it became available at the //BUILD conference in 2011, and when I recently came to work at Stackify, it was one of the first changes I made. Managing work items is much easier than the tool we were using previously, although there are some limitations (more on that in another blog post). However, when continuous deployment was made available, it blew my mind. It was the killer feature I didn’t know I needed. Not to say that I wasn’t previously an advocate for continuous delivery; just that it was always a pain to set up and configure. Having it hosted - and a one-click setup – well, that’s just the best thing since sliced bread. It made perfect sense: my source code is in the cloud, and my deployment is in the cloud. Great! I can queue up a build from my iPad or phone and just let it go! I quickly tore through the quick setup and saw it all work… sort of. This will be the first in a three part series on how to take the building block of Team Foundation Service continuous delivery and build a CD model that will actually work for any team deploying something more advanced than a “Hello World” example. Part 1: Good Enough Is Not Great Part 2: A Model That Works: Branching and Multiple Deployment Environments Part 3: Other Considerations: SQL, Custom Tasks, Etc Good Enough Is Not Great There. I’ve said it. I certainly hope no one on the TFS team is offended, but it’s the truth. Let’s take a look under the hood and understand how it works, and then why it’s not enough to handle real world CD as-is. How it works. (note that I’ve skipped a couple of steps; I already have my accounts set up and something deployed to Azure) The first step is to establish some oAuth magic between your Azure management portal and your TFS Instance. You do this via the management portal. Once it’s done, you have a new build process template in your TFS instance. (Image lifted from the documentation) From here, you’ll get the usual prompts for security, allowing access, etc. But you’ll also get to pick which Solution in your source control to build. Here’s what the bulk of the build definition looks like. All I’ve had to do is add in the solution to build (notice that mine is from a specific branch – Release – more on that later) and I’ve changed the configuration. I trigger the build, and voila! I have an Azure deployment a few minutes later. The beauty of this is that it’s all in the cloud and I’m not waiting for my machine to compile and upload the package. (I also had to enable the build definition first – by default it is created in disabled state, probably a good thing since it will trigger on every.single.checkin by default.) I get to see a history of deployments from the Azure portal, and can link into TFS to see the associated changesets and work items. You’ll notice also that this build definition also automatically put my code in the Staging slot of my Azure deployment – more on this soon. For now, I can VIP swap and be in production. (P.S. I hate VIP swap and “production” and “staging” in Azure. More on that later too.) That’s it. That’s the default out-of-box experience. Easy, right? But it’s full of room for improvement, so let’s get into that….   The Problems Nothing is perfect (except my code – it’s always perfect), and neither is Continuous Deployment without a bit of work to help it fit your dev team’s process. So what are the issues? Issue 1: Staging vs QA vs Prod vs whatever other environments your team may have. This, for me, is the big hairy one. Remember how this automatically deployed to staging rather than prod for us? There are a couple of issues with this model: If I want to deliver to prod, it requires intervention on my part after deployment (via a VIP swap). If I truly want to promote between environments (i.e. Nightly Build –> Stable QA –> Production) I likely have configuration changes between each environment such as database connection strings and this process (and the VIP swap) doesn’t account for this. Yet. Issue 2: Branching and delivering on every check-in. As I mentioned above, I have set this up to target a specific branch – Release – of my code. For the purposes of this example, I have adopted the “basic” branching strategy as defined by the ALM Rangers. This basically establishes a “Main” trunk where you branch off Dev and Release branches. Granted, the Release branch is usually the only thing you will deploy to production, but you certainly don’t want to roll to production automatically when you merge to the Release branch and check-in (unless you like the thrill of it, and in that case, I like your style, cowboy….). Rather, you have nightly build and QA environments, or if you’ve adopted the feature-branch model you have environments for those. Those are the environments you want to continuously deploy to. But that takes us back to Issue 1: we currently have a 1:1 solution to Azure deployment target. Issue 3: SQL and other custom tasks. Let’s be honest and address the elephant in the room: I need to get some sleep because I see an elephant in the room. But seriously, I can’t think of an application I have touched in the last 10 years that doesn’t need to consider SQL changes when deploying code and upgrading an environment. Microsoft seems perfectly content to ignore this elephant for now: yes, they’ve added Data Tier Applications. But let’s be honest with ourselves again: no one really uses it, and it’s not suitable for anything more complex than a Hello World sample project database. Why? Because it doesn’t fit well into a great source control story. Developers make stored procedure and table changes all day long while coding complex applications, and if someone forgets to go update the DACPAC before the automated deployment, you have a broken build until it’s completed. Developers – not just DBAs – also like to work with SQL in SQL tools, not in Visual Studio. I’m really picking on SQL because that’s generally the biggest concern that I hear. But we need to account for any custom tasks as well in the build process.   The Solutions… ? We’ve taken a look at how this all works, and addressed the shortcomings. In my next post (which I promise will be very, very soon), I will detail how I’ve overcome these shortcomings and used this foundation to create a mature, flexible model for deploying my app – any version, any time, to any environment.

• Attribute Overwriting in MDX

  - by Marco Russo (SQLBI)

  Jeffrey Wang wrote a great blog post about attribute overwriting in MDX that is very clear and full of helpful pictures to show what happens when you write an MDX statement that writes into your multidimensional space. This is very common in an MDX Script and if you tried to customize the DateTool solution you probably experienced how hard this concept can be. The point is not that MDX is hard, is that a model based on multiple hierarchies in a dimension (and each attribute is a hierarchy by default!)...(read more)

• Scan Your Thumb Drive for Viruses from the AutoPlay Dialog

  - by Mysticgeek

  It’s always a good idea to scan someone’s flash drive for viruses when you use it on your PC. Today we look at how to use Microsoft Security Essentials to scan thumb drives via the AutoPlay dialog. Editor Note: This technique was created by our friend Ramesh Srinivasan from the winhelponline tech blog. If you haven’t done so already, download and install Microsoft Security Essentials (link below), which has earned the How-To Geek official endorsement. Next download the mseautoplay.zip (link below). Unzip the file to view its contents. Then move the msescan.vbs script file into the Windows directory. Next double-click on the mseautoplay.reg file… Click Yes to the warning dialog window asking if you’re sure you want to add to the registry. After it’s added you’ll get a confirmation message…click OK. Now when you pop in a thumb drive, when AutoPlay comes up you will have the options to scan it with MSE first. MSE starts the scan of the thumb drive…   You can use this to scan any removable media. Here is an example of the ability to scan a DVD with MSE before opening any files. You can also go into Control Panel and set it as a default option of AutoPlay. Open Control Panel, View by Large icons, and click on AutoPlay. Notice that now when you go to change the default options for different types of media, Scanning with MSE is now included in the dropdown lists. Remove Settings If you want to remove the MSE AutoPlay Handler, Ramesh was kind enough to create an undo registry file. Double-click on undo.reg from the original MSE AutoPlay folder and click yes to the message to remove the setting.   Then you will need to go into the Windows directory and manually delete the msescan.vbs script file. This is an awesome trick which will allow you to scan your thumb drives and other removable media from the AutoPlay dialog. We tested it out on XP, Vista, and Windows 7 and it works perfectly on each one.

• Why Clonezilla needs to reinstall grub?

  - by Pablo

  By default CloneZilla Live will reinstall grub after restore. In my particular case I am restoring a disk image to same phisical disk without any partitioning/size change. I am expecting to have exact same state as I had right after backup. However, reinstalling grub will render my system to unbootable. If I remove that option [-g] then everything is fine. My question is in what cases and why CloneZilla ever need to re-install grub when restoring disk image?

• Customize the Background in Boxee

  - by DigitalGeekery

  Are you a Boxee user who thinks the default background is little boring? Today we’ll take a look at how to freshen up the look of Boxee by changing the background. Boxee Background When you log into Boxee, select the Settings button at the upper left corner of the Home page.   Select General on the Settings screen. When you select or hover your mouse over the Background Image button, you’ll see options to set a background image or set a background image folder. You’ll have the option of settings a single static image as your background, or choosing an images folder.   If you choose a folder, Boxee will rotate through the images in the folder. To set Background images folder, select that option. Browse for your image folder.. And then select OK.   Boxee will rotate through the images in the folder.   Images will change every ten seconds.   If you prefer a single static image, select Set background image   Choose a image and select OK. Now just enjoy you nice new backgrounds.   If you ever wish to revert back to the default Boxee background, simply select Reset Images on the Settings \ General screen. Adding your own backgrounds is a nice way to customize your Boxee experience. Ideally, you’ll want to choose high resolution images and images oriented as landscape rather than portrait.

• permanently load module

  - by Radu

  I have a Compaq Presario CQ-61 320SQ, I am using Ubuntu 10.04 because after update to 10.10 my mouse and touchpad won't work, network won't work, sound won't work ... (I managed to fix most of them after almost a month of googling, but not all, my 2 Desktops have no problem with 10.10) so I decided to switch back to 10.04, where I have a problem: My broadband speed is very low beacause of the kernel module r8169, I downloaded the good module r8101 and every time the computer boots have a rc.local entry to fix this. Question: Can I load the modul permanently from a specific location. I heard about /etc/modules but there I need the module name, but I have to load it from a specific path (where is the default path for that) Thank you. So I studied the script: It creates the file r8101.ko in /lib/modules/uname -r/kernel/drivers/net so I think as long as nobody will delete that file, and I don't update the kernel, maybe adding r8108 to /etc/modules will work, and add r8169 to blacklist ... I will give it a try. EDIT2: So I added r8101 to /etc/modules and blacklist r8169 to /etc/modprobe.d/blacklist.conf It still uses the old module, lsmod prints: radu@adu:~$ lsmod | grep r8 r8101 67626 0 r8169 34108 0 mii 4381 1 r8169 EDIT: the module is loaded using this script that came with it: #!/bin/sh # invoke insmod with all arguments we got # and use a pathname, as insmod doesn't look in . by default TARGET_PATH=/lib/modules/`uname -r`/kernel/drivers/net echo echo "Check old driver and unload it." check=`lsmod | grep r8169` if [ "$check" != "" ]; then echo "rmmod r8169" /sbin/rmmod r8169 fi check=`lsmod | grep r8101` if [ "$check" != "" ]; then echo "rmmod r8101" /sbin/rmmod r8101 fi echo "Build the module and install" echo "-------------------------------" >> log.txt date 1>>log.txt make all 1>>log.txt || exit 1 module=`ls src/*.ko` module=${module#src/} module=${module%.ko} if [ "$module" == "" ]; then echo "No driver exists!!!" exit 1 elif [ "$module" != "r8169" ]; then if test -e $TARGET_PATH/r8169.ko ; then echo "Backup r8169.ko" if test -e $TARGET_PATH/r8169.bak ; then i=0 while test -e $TARGET_PATH/r8169.bak$i do i=$(($i+1)) done echo "rename r8169.ko to r8169.bak$i" mv $TARGET_PATH/r8169.ko $TARGET_PATH/r8169.bak$i else echo "rename r8169.ko to r8169.bak" mv $TARGET_PATH/r8169.ko $TARGET_PATH/r8169.bak fi fi fi echo "Depending module.

They both work, but display server assigned to Intel card doesn't have hardware acceleration since DRI and GLX module being used is from nVidia driver. So my question is, can I configure layouts somehow to use right DRI and GLX with each card?

• How to Format a USB Drive in Ubuntu Using GParted

  - by Trevor Bekolay

  If a USB hard drive or flash drive is not properly formatted, then it will not show up in the Ubuntu Places menu, making it hard to interact with. We’ll show you how to format a USB drive using the tool GParted. Note: Formatting a USB drive will destroy any data currently stored on it. If you think that your USB drive is already properly formatted, but Ubuntu just isn’t picking it up, try unplugging it and plugging it back in to a different USB slot, or restarting your machine with the device plugged in on start-up. Open a terminal by clicking on Applications in the top-left of the screen, then Accessories > Terminal. GParted should be installed by default, but we’ll make sure it’s installed by entering the following command in the terminal: sudo apt-get install gparted To open GParted, enter the following command in the terminal: sudo gparted Find your USB drive in the drop-down box at the top right of the GParted window. The drive should be unallocated – if it has a valid partition on it, then you may be looking at the wrong drive. Note: Make sure you’re on the correct drive, as making changes on the wrong hard drive with GParted can delete all data on a hard drive! Assuming you’re on the right drive, right-click on the unallocated grey block and click New. In the window that pops up, change the File System to fat32 for USB Flash Drives, NTFS for USB Hard Drives that will be used in Windows, or ext3/ext4 for USB Hard Drives that will be used exclusively in Linux. Add a label if you’d like, and then click Add. Click the green checkmark and then the Apply button to apply the changes. GParted will now format your drive. If you’re formatting a large USB Hard Drive, this can take some time. Once the process is done, you can close GParted, and the drive will now show up in the Places menu. Clicking on the drive will mount it and open it in a File Browser window. It will also add a shortcut to the drive on the Desktop by default. Your USB drive is now ready to store your files!

• Lubuntu Desktop messed up for logged in user, but not for guest

  - by RPi Awesomeness

  I recently upgraded my laptop from Lubuntu 12.04 to 14.04.1 and the upgrade process seemed to go fine. However, when I went to login as my normal user, I encountered an issue. The background loaded up, but none of LXDE or LXPanel showed up, leaving me with an empty desktop and nothing else except two errors. I thought that this was weird, so I just figured something had been messed up and would be fixed by a reboot. But it wasn't. I then tried logging in as guest, and it's just fine. I checked the ~/.xsession-errors file (for my main user, not guest, did it via TTY1) and this is what I got: Script for ibus started at run_im. Script for auto started at run_im. Script for default started at run_im. init: Unable to register as subreaper: Invalid argument init: lxsession main process (1649) killed by TERM signal init: Disconnected from notified D-Bus bus init: job dbus failed to stop init: job upstart-dbus-session-bridge failed to stop init: job upstart-dbus-system-bridge failed to stop init: job upstart-file-bridge failed to stop I also read the sometimes removing the ~/.Xauthority file can help, if the ownership is messed up. ls -l /home/MYUSER/.Xauthority tells me -rw------- 1 MYUSER MYUSER 60 Aug 16 09:57 /home/MYUSER/.Xauthority. Should that be root or something else, or should I try deleting that and ~/.profile. Here's what ~/.profile looks like: # ~/.profile: executed by the command interpreter for login shells. # This file is not read by bash(1), if ~/.bash_profile or ~/.bash_login # exists. # see /usr/share/doc/bash/examples/startup-files for examples. # the files are located in the bash-doc package. # the default umask is set in /etc/profile; for setting the umask # for ssh logins, install and configure the libpam-umask package. #umask 022 # if running bash if [ -n "$BASH_VERSION" ]; then # include .bashrc if it exists if [ -f "$HOME/.bashrc" ]; then . "$HOME/.bashrc" fi fi # set PATH so it includes user's private bin if it exists if [ -d "$HOME/bin" ] ; then PATH="$HOME/bin:$PATH" fi Should I post the output of dmesg? I'll try and get a screenshot, but does anyone have any idea what could be causing the desktop (LXDE/LXPanel) not to display? EDIT I attempted removing the ~/.XAuthority file, but that didn't seem to do anything.

• How do I fix my theme?

  - by SepiDev

  After installing and using Ubuntu 11.10 for while I decided to install gnome shell. After Installing and rebooting my system I saw that Ubuntu light theme (ambiance/radiance) is gone. I check /usr/shar/themes and /usr/shar/icons, it seems that the light themes and mono icons exist. I even reinstalled gtk3-engine-unico package but none of these effort fixed my problem :( my desktop now looks like this: What should I do to get my default ubuntu theme back?

• Backlight Issue

  - by Shubham

  When I booted up my newly installed Ubuntu 11.04, I discovered, to my dismay, that the backlight was off by default. The keyboard shortcut (which is Fn+F6 on my Acer Aspire 4736) for turning on the backlight doesn't seem to work. I have been trying to resolve this problem for the past 2 days now, but with no success. By the way, the backlight did work properly once or twice at random - but the problem again popped up as soon as I restarted my system.

• Visual Studio 2010 plus Help Index : have your cake and eat it too

  - by Adrian Hara

  Although the team's intentions might have been good, the new help system in Visual Studio 2010  is a huge step backwards (more like a cannonball-shot-kind-of-leap really) from the one we all know (and love?) in Visual Studio 2008 and 2005 (and heck, even VS6). Its biggest problem, from my point of view, is the total and complete lack of the Help Index feature: you know...the thing where you just go and type in what you're looking for and it filters down the list of results automatically. For me this was the number one productivity feature in the "old" help system, allowing me to find stuff very quickly. Number two is that it's entirely web based and runs, by default, in the browser. So imagine, when you press F1, a new tab opens in your default browser pointing to the help entry. While this is wrong in many ways, it's also extremely annoying, cleaning up tabs in the browser becomes a chore which represents a serious productivity hit. These and many other problems were discussed extensively (and rather vocally) on connect but it seems MS seemed to ignore it and opt to release the new help system anyway, with the promise that more features will be added in a later release. Again, it kind of amazes me that they chose to ship a product with LESS features that the previous one and, what's worse, missing KEY features, just so it's "standards based" and "extensible". To be honest, I couldn't care less about the help system's implementation, I just want it to be usable and I would've thought that by now the software community and especially MS would've learned this lesson. In the end, what kind of saddens me is that MS regards these basic features as ones for the "power help user". I mean, come on! I mean a) it's not like my aunt's using Visual Studio 2010 and she represents the regular user, b) all software developers are, by definition, power users and c) it's a freakin help, not rocket science! As you can tell, I'm pretty pissed. Even more so because I really feel that the VS2010 & co. release really is a great one, with a lot of effort going into the various platforms and frameworks, most (if not all) of them being really REALLY good products. And then they go and screw up the help! How lame is that?!   Anyway, it's not all gloom-and-doom. Luckily there is a desktop app which presents a UI over the new help system that's very close to what was there in VS2008, by Robert Chandler (to which I hereby declare eternal gratitude). It still has some minor issues but I'll take it over the browser version of the help any day. It's free, pretty quick (on my machine ;)) and nicely usable. So, if you hate the new help system (passionately) like I do, download H3Viewer now.

• Domain masking (and simple page links)

  - by Halik

  How do you set up the domain (Im using godaddy) to mask the server url but to append the sub-page link. Im thinking something like the wikipedia en.wikipedia.org/wiki/something (or, if it would require httpd.conf access, setting it to append the default subpage link eg. '?page_id=2') Currently I can set up the domain to either be masked completely without showing any sub-page links or to simply redirect my domain to my web server.

  Background Designing Stored Procedures that are safe for multiple subscribers (to call simultaneously) can be challenging.  For example let’s say that you want multiple worker processes to poll a shared work queue that’s encapsulated as a SQL Table. This is a common scenario and through experience you’ll find that you want to use Table Hints to prevent unwanted locking when performing simultaneous queries on the same table. There are three table hints to consider: NOLOCK, READPAST and UPDLOCK. Both NOLOCK and READPAST table hints allow you to SELECT from a table without placing a LOCK on that table. However, SELECTs with the READPAST hint will ignore any records that are locked due to being updated/inserted (or otherwise “dirty”), whereas a SELECT with NOLOCK ignores all locks including dirty reads. For the initial update of the flag (that marks the record as available for subscription) I don’t use the NOLOCK Table Hint because I want to be sensitive to the “active” records in the table and I want to exclude them.  I use an Update Lock (UPDLOCK) in conjunction with a WHERE clause that uses a sub-select with a READPAST Table Hint in order to explicitly lock the records I’m updating (UPDLOCK) but not place a lock on the table when selecting the records that I’m going to update (READPAST). UPDATES should be allowed to lock the rows affected because we’re probably changing a flag on a record so that it is not included in a SELECT from another subscriber. On the UPDATE statement we should explicitly use the UPDLOCK to guard against lock escalation. A SELECT to check for the next record(s) to process can result in a shared read lock being held by more than one subscriber polling the shared work queue (SQL table). It is expected that more than one worker process (or server) might try to process the same new record(s) at the same time. When each process then tries to obtain the update lock, none of them can because another process has a shared read lock in place. Thus without the UPDLOCK hint the result would be a lock escalation deadlock; however with the UPDLOCK hint this condition is mitigated against. Note that using the READPAST table hint requires that you also set the ISOLATION LEVEL of the transaction to be READ COMMITTED (rather than the default of SERIALIZABLE). Guidance In the Stored Procedure that returns records to the multiple subscribers: Perform the UPDATE first. Change the flag that makes the record available to subscribers.  Additionally, you may want to update a LastUpdated datetime field in order to be able to check for records that “got stuck” in an intermediate state or for other auditing purposes. In the UPDATE statement use the (UPDLOCK) Table Hint on the UPDATE statement to prevent lock escalation. In the UPDATE statement also use a WHERE Clause that uses a sub-select with a (READPAST) Table Hint to select the records that you’re going to update. In the UPDATE statement use the OUTPUT clause in conjunction with a Temporary Table to isolate the record(s) that you’ve just updated and intend to return to the subscriber. This is the fastest way to update the record(s) and to get the records’ identifiers within the same operation. Finally do a set-based SELECT on the main Table (using the Temporary Table to identify the records in the set) with either a READPAST or NOLOCK table hint.  Use NOLOCK if there are other processes (besides the multiple subscribers) that might be changing the data that you want to return to the multiple subscribers; or use READPAST if you're sure there are no other processes (besides the multiple subscribers) that might be updating column data in the table for other purposes (e.g. changes to a person’s last name).  NOLOCK is generally the better fit in this part of the scenario. See the following as an example: CREATE PROCEDURE [dbo].[usp_NewCustomersSelect] AS BEGIN -- OVERRIDE THE DEFAULT ISOLATION LEVEL SET TRANSACTION ISOLATION LEVEL READ COMMITTED -- SET NOCOUNT ON SET NOCOUNT ON -- DECLARE TEMP TABLE -- Note that this example uses CustomerId as an identifier; -- you could just use the Identity column Id if that’s all you need. DECLARE @CustomersTempTable TABLE ( CustomerId NVARCHAR(255) ) -- PERFORM UPDATE FIRST -- [Customers] is the name of the table -- [Id] is the Identity Column on the table -- [CustomerId] is the business document key used to identify the -- record globally, i.e. in other systems or across SQL tables -- [Status] is INT or BIT field (if the status is a binary state) -- [LastUpdated] is a datetime field used to record the time of the -- last update UPDATE [Customers] WITH (UPDLOCK) SET [Status] = 1, [LastUpdated] = GETDATE() OUTPUT [INSERTED].[CustomerId] INTO @CustomersTempTable WHERE ([Id] = (SELECT TOP 100 [Id] FROM [Customers] WITH (READPAST) WHERE ([Status] = 0) ORDER BY [Id] ASC)) -- PERFORM SELECT FROM ENTITY TABLE SELECT [C].[CustomerId], [C].[FirstName], [C].[LastName], [C].[Address1], [C].[Address2], [C].[City], [C].[State], [C].[Zip], [C].[ShippingMethod], [C].[Id] FROM [Customers] AS [C] WITH (NOLOCK), @CustomersTempTable AS [TEMP] WHERE ([C].[CustomerId] = [TEMP].[CustomerId]) END In a system that has been designed to have multiple status values for records that need to be processed in the Work Queue it is necessary to have a “Watch Dog” process by which “stale” records in intermediate states (such as “In Progress”) are detected, i.e. a [Status] of 0 = New or Unprocessed; a [Status] of 1 = In Progress; a [Status] of 2 = Processed; etc.. Thus, if you have a business rule that states that the application should only process new records if all of the old records have been processed successfully (or marked as an error), then it will be necessary to build a monitoring process to detect stalled or stale records in the Work Queue, hence the use of the LastUpdated column in the example above. The Status field along with the LastUpdated field can be used as the criteria to detect stalled / stale records. It is possible to put this watchdog logic into the stored procedure above, but I would recommend making it a separate monitoring function. In writing the stored procedure that checks for stale records I would recommend using the same kind of lock semantics as suggested above. The example below looks for records that have been in the “In Progress” state ([Status] = 1) for greater than 60 seconds: CREATE PROCEDURE [dbo].[usp_NewCustomersWatchDog] AS BEGIN -- TO OVERRIDE THE DEFAULT ISOLATION LEVEL SET TRANSACTION ISOLATION LEVEL READ COMMITTED -- SET NOCOUNT ON SET NOCOUNT ON DECLARE @MaxWait int; SET @MaxWait = 60 IF EXISTS (SELECT 1 FROM [dbo].[Customers] WITH (READPAST) WHERE ([Status] = 1) AND (DATEDIFF(s, [LastUpdated], GETDATE()) > @MaxWait)) BEGIN SELECT 1 AS [IsWatchDogError] END ELSE BEGIN SELECT 0 AS [IsWatchDogError] END END Downloads The zip file below contains two SQL scripts: one to create a sample database with the above stored procedures and one to populate the sample database with 10,000 sample records.  I am very grateful to Red-Gate software for their excellent SQL Data Generator tool which enabled me to create these sample records in no time at all.

• Per-vertex position/normal and per-index texture coordinate

  - by Boreal

  In my game, I have a mesh with a vertex buffer and index buffer up and running. The vertex buffer stores a Vector3 for the position and a Vector2 for the UV coordinate for each vertex. The index buffer is a list of ushorts. It works well, but I want to be able to use 3 discrete texture coordinates per triangle. I assume I have to create another vertex buffer, but how do I even use it? Here is my vertex/index buffer creation code: // vertices is a Vertex[] // indices is a ushort[] // VertexDefs stores the vertex size (sizeof(float) * 5) // vertex data numVertices = vertices.Length; DataStream data = new DataStream(VertexDefs.size * numVertices, true, true); data.WriteRange<Vertex>(vertices); data.Position = 0; // vertex buffer parameters BufferDescription vbDesc = new BufferDescription() { BindFlags = BindFlags.VertexBuffer, CpuAccessFlags = CpuAccessFlags.None, OptionFlags = ResourceOptionFlags.None, SizeInBytes = VertexDefs.size * numVertices, StructureByteStride = VertexDefs.size, Usage = ResourceUsage.Default }; // create vertex buffer vertexBuffer = new Buffer(Graphics.device, data, vbDesc); vertexBufferBinding = new VertexBufferBinding(vertexBuffer, VertexDefs.size, 0); data.Dispose(); // index data numIndices = indices.Length; data = new DataStream(sizeof(ushort) * numIndices, true, true); data.WriteRange<ushort>(indices); data.Position = 0; // index buffer parameters BufferDescription ibDesc = new BufferDescription() { BindFlags = BindFlags.IndexBuffer, CpuAccessFlags = CpuAccessFlags.None, OptionFlags = ResourceOptionFlags.None, SizeInBytes = sizeof(ushort) * numIndices, StructureByteStride = sizeof(ushort), Usage = ResourceUsage.Default }; // create index buffer indexBuffer = new Buffer(Graphics.device, data, ibDesc); data.Dispose(); Engine.Log(MessageType.Success, string.Format("Mesh created with {0} vertices and {1} indices", numVertices, numIndices)); And my drawing code: // ShaderEffect, ShaderTechnique, and ShaderPass all store effect data // e is of type ShaderEffect // get the technique ShaderTechnique t; if(!e.techniques.TryGetValue(techniqueName, out t)) return; // effect variables e.SetMatrix("worldView", worldView); e.SetMatrix("projection", projection); e.SetResource("diffuseMap", texture); e.SetSampler("textureSampler", sampler); // set per-mesh/technique settings Graphics.context.InputAssembler.SetVertexBuffers(0, vertexBufferBinding); Graphics.context.InputAssembler.SetIndexBuffer(indexBuffer, SlimDX.DXGI.Format.R16_UInt, 0); Graphics.context.PixelShader.SetSampler(sampler, 0); // render for each pass foreach(ShaderPass p in t.passes) { Graphics.context.InputAssembler.InputLayout = p.layout; p.pass.Apply(Graphics.context); Graphics.context.DrawIndexed(numIndices, 0, 0); } How can I do this?

• Can I change Synapse shortcut to Super/Windows key alone?

  - by Capt.Nemo

  When I'm trying to edit synapse config, it does not allow me to use Super_L as a direct shortcut for invoking it. Is there a round-about way that I can go through. When I just press the Windows/Super key, the configuration window does not acknowledge it. However, a combination shortcut (such as Super+a) do work fine. Since I'm using Precise, with unity, I'd also need a way to change the default dash behavior from Windows/Super key to something else.

• Log Debug Messages without Debug Serial on Shipped Device

  - by Kate Moss' Open Space

  Debug message is one of the ancient but useful way for problem resolving. Message is redirected to PB if KITL is enabled otherwise it goes to default debug port, usually a serial port on most of the platform but it really depends on how OEMWriteDebugString and OEMWriteDebugByte are implemented. For many reasons, we don't want to have a debug serial port, for example, we don't have enough spare serial ports and it can affect the performance. So some of the BSP designers decide to dump the messages into other media, could be a log file, shared memory or any solution that is suitable for the need. In CE 5.0 and previous, OAL and Kernel are linked into one binaries; in the other word, you can use whatever function in kernel, such as SC_CreateFileW to access filesystem in OAL, even this is strongly not recommended. But since the OAL is being a standalone executable in CE 6.0, we no longer can use this back door but only interface exported in NKGlobal which just provides enough for OAL but no more. Accessing filesystem or using sync object to communicate to other drivers or application is even not an option. Sounds like the kernel lock itself up; of course, OAL is in kernel space, you can still do whatever you want to hack into kernel, but once again, it is not only make it a dirty solution but also fragile. So isn't there an elegant solution? Let's see how a debug message print out. In private\winceos\COREOS\nk\kernel\printf.c, the OutputDebugStringW is the one for pumping out the messages; most of the code is for error handling and serialization but what really interesting is the following code piece     if (g_cInterruptsOff) {         OEMWriteDebugString ((unsigned short *)str);     } else {         g_pNKGlobal->pfnWriteDebugString ((unsigned short *)str);     }     CELOG_OutputDebugString(dwActvProcId, dwCurThId, str); It outputs the message to default debug output (is redirected to KITL when available) or OAL when needed but note that highlight part, it also invokes CELOG_OutputDebugString. Follow the thread to private\winceos\COREOS\nk\logger\CeLogInstrumentation.c, this function dump whatever input to CELOG. So whatever the debug message is we always got a clone in CELOG. General speaking, all of the debug message is logged to CELOG already, so what you need to do is using celogflush.exe with CELZONE_DEBUG zone, and then viewing the data using the by Readlog tool. Here are some information about these tools CELOG - http://msdn.microsoft.com/en-us/library/ee479818.aspx READLOG - http://msdn.microsoft.com/en-us/library/ee481220.aspx Also for advanced reader, I encourage you to dig into private\winceos\COREOS\nk\celog\celogdll, the source of CELOG.DLL and use it as a starting point to create a more lightweight debug message logger for your own device!

• Changing swappiness in sysctl.conf doesn't work for me

  - by Graham

  I'm using 12.04 LTS and can sudo sysctl to set swappiness to 10, but adding vm.swappiness=10 to sysctl.conf doesn't work for me - after I reboot, swappiness still reports 60 (default) I'd like to be able to reduce swaps to my SSD, but can't find a way to do so except manually per session. Modifying sysctl.conf seems to work for most - can anyone advise what I need to check / change to make it work for me too, please?
