  • Error "exit signal Bus error (7)" How to continue after making a backtrace?

    - by Mikel
    I have a Centos Server in 1and1 with Apache, Magento, MagentoBooster and Xcache installed. The server usually (1-8 times per day) prints this error "exit signal Bus error (7)" and sometimes this causes Apache not to respond. I have made a backtrace with GDB, but I don't know how to continue. gdb /usr/sbin/httpd core.XXXX --batch --quiet -ex "thread apply all bt full" backtrace.log The backtrace: [New Thread 15312] [Thread debugging using libthread_db enabled] Core was generated by `/usr/sbin/httpd'.

  • Application running in the iPad Simulator

    - by Wallym
    I've got some code running in the iPad Simulator.  One thing I discovered is that an application has to be compiled against a specific version of the SDK.  When I created a new iPad application, the updated iPad window for the Interface Builder became availble.  Very nice indeed.  Everything was the same as before, so that was good.  I fired up the iPad Simulator, and I got this below:   The next step was getting my app on there, which was easy.  Then I got my app running on the simulator, and I saw this: Basically, everything is filled with goodness and seems to be running correctly.  **fingers crossed**

  • Scrum in 5 Minutes

    - by Stephen.Walther
    The goal of this blog entry is to explain the basic concepts of Scrum in less than five minutes. You learn how Scrum can help a team of developers to successfully complete a complex software project. Product Backlog and the Product Owner Imagine that you are part of a team which needs to create a new website – for example, an e-commerce website. You have an overwhelming amount of work to do. You need to build (or possibly buy) a shopping cart, install an SSL certificate, create a product catalog, create a Facebook page, and at least a hundred other things that you have not thought of yet. According to Scrum, the first thing you should do is create a list. Place the highest priority items at the top of the list and the lower priority items lower in the list. For example, creating the shopping cart and buying the domain name might be high priority items and creating a Facebook page might be a lower priority item. In Scrum, this list is called the Product Backlog. How do you prioritize the items in the Product Backlog? Different stakeholders in the project might have different priorities. Gary, your division VP, thinks that it is crucial that the e-commerce site has a mobile app. Sally, your direct manager, thinks taking advantage of new HTML5 features is much more important. Multiple people are pulling you in different directions. According to Scrum, it is important that you always designate one person, and only one person, as the Product Owner. The Product Owner is the person who decides what items should be added to the Product Backlog and the priority of the items in the Product Backlog. The Product Owner could be the customer who is paying the bills, the project manager who is responsible for delivering the project, or a customer representative. The critical point is that the Product Owner must always be a single person and that single person has absolute authority over the Product Backlog. Sprints and the Sprint Backlog So now the developer team has a prioritized list of items and they can start work. The team starts implementing the first item in the Backlog — the shopping cart — and the team is making good progress. Unfortunately, however, half-way through the work of implementing the shopping cart, the Product Owner changes his mind. The Product Owner decides that it is much more important to create the product catalog before the shopping cart. With some frustration, the team switches their developmental efforts to focus on implementing the product catalog. However, part way through completing this work, once again the Product Owner changes his mind about the highest priority item. Getting work done when priorities are constantly shifting is frustrating for the developer team and it results in lower productivity. At the same time, however, the Product Owner needs to have absolute authority over the priority of the items which need to get done. Scrum solves this conflict with the concept of Sprints. In Scrum, a developer team works in Sprints. At the beginning of a Sprint the developers and the Product Owner agree on the items from the backlog which they will complete during the Sprint. This subset of items from the Product Backlog becomes the Sprint Backlog. During the Sprint, the Product Owner is not allowed to change the items in the Sprint Backlog. In other words, the Product Owner cannot shift priorities on the developer team during the Sprint. Different teams use Sprints of different lengths such as one month Sprints, two-week Sprints, and one week Sprints. For high-stress, time critical projects, teams typically choose shorter sprints such as one week sprints. For more mature projects, longer one month sprints might be more appropriate. A team can pick whatever Sprint length makes sense for them just as long as the team is consistent. You should pick a Sprint length and stick with it. Daily Scrum During a Sprint, the developer team needs to have meetings to coordinate their work on completing the items in the Sprint Backlog. For example, the team needs to discuss who is working on what and whether any blocking issues have been discovered. Developers hate meetings (well, sane developers hate meetings). Meetings take developers away from their work of actually implementing stuff as opposed to talking about implementing stuff. However, a developer team which never has meetings and never coordinates their work also has problems. For example, Fred might get stuck on a programming problem for days and never reach out for help even though Tom (who sits in the cubicle next to him) has already solved the very same problem. Or, both Ted and Fred might have started working on the same item from the Sprint Backlog at the same time. In Scrum, these conflicting needs – limiting meetings but enabling team coordination – are resolved with the idea of the Daily Scrum. The Daily Scrum is a meeting for coordinating the work of the developer team which happens once a day. To keep the meeting short, each developer answers only the following three questions: 1. What have you done since yesterday? 2. What do you plan to do today? 3. Any impediments in your way? During the Daily Scrum, developers are not allowed to talk about issues with their cat, do demos of their latest work, or tell heroic stories of programming problems overcome. The meeting must be kept short — typically about 15 minutes. Issues which come up during the Daily Scrum should be discussed in separate meetings which do not involve the whole developer team. Stories and Tasks Items in the Product or Sprint Backlog – such as building a shopping cart or creating a Facebook page – are often referred to as User Stories or Stories. The Stories are created by the Product Owner and should represent some business need. Unlike the Product Owner, the developer team needs to think about how a Story should be implemented. At the beginning of a Sprint, the developer team takes the Stories from the Sprint Backlog and breaks the stories into tasks. For example, the developer team might take the Create a Shopping Cart story and break it into the following tasks: · Enable users to add and remote items from shopping cart · Persist the shopping cart to database between visits · Redirect user to checkout page when Checkout button is clicked During the Daily Scrum, members of the developer team volunteer to complete the tasks required to implement the next Story in the Sprint Backlog. When a developer talks about what he did yesterday or plans to do tomorrow then the developer should be referring to a task. Stories are owned by the Product Owner and a story is all about business value. In contrast, the tasks are owned by the developer team and a task is all about implementation details. A story might take several days or weeks to complete. A task is something which a developer can complete in less than a day. Some teams get lazy about breaking stories into tasks. Neglecting to break stories into tasks can lead to “Never Ending Stories” If you don’t break a story into tasks, then you can’t know how much of a story has actually been completed because you don’t have a clear idea about the implementation steps required to complete the story. Scrumboard During the Daily Scrum, the developer team uses a Scrumboard to coordinate their work. A Scrumboard contains a list of the stories for the current Sprint, the tasks associated with each Story, and the state of each task. The developer team uses the Scrumboard so everyone on the team can see, at a glance, what everyone is working on. As a developer works on a task, the task moves from state to state and the state of the task is updated on the Scrumboard. Common task states are ToDo, In Progress, and Done. Some teams include additional task states such as Needs Review or Needs Testing. Some teams use a physical Scrumboard. In that case, you use index cards to represent the stories and the tasks and you tack the index cards onto a physical board. Using a physical Scrumboard has several disadvantages. A physical Scrumboard does not work well with a distributed team – for example, it is hard to share the same physical Scrumboard between Boston and Seattle. Also, generating reports from a physical Scrumboard is more difficult than generating reports from an online Scrumboard. Estimating Stories and Tasks Stakeholders in a project, the people investing in a project, need to have an idea of how a project is progressing and when the project will be completed. For example, if you are investing in creating an e-commerce site, you need to know when the site can be launched. It is not enough to just say that “the project will be done when it is done” because the stakeholders almost certainly have a limited budget to devote to the project. The people investing in the project cannot determine the business value of the project unless they can have an estimate of how long it will take to complete the project. Developers hate to give estimates. The reason that developers hate to give estimates is that the estimates are almost always completely made up. For example, you really don’t know how long it takes to build a shopping cart until you finish building a shopping cart, and at that point, the estimate is no longer useful. The problem is that writing code is much more like Finding a Cure for Cancer than Building a Brick Wall. Building a brick wall is very straightforward. After you learn how to add one brick to a wall, you understand everything that is involved in adding a brick to a wall. There is no additional research required and no surprises. If, on the other hand, I assembled a team of scientists and asked them to find a cure for cancer, and estimate exactly how long it will take, they would have no idea. The problem is that there are too many unknowns. I don’t know how to cure cancer, I need to do a lot of research here, so I cannot even begin to estimate how long it will take. So developers hate to provide estimates, but the Product Owner and other product stakeholders, have a legitimate need for estimates. Scrum resolves this conflict by using the idea of Story Points. Different teams use different units to represent Story Points. For example, some teams use shirt sizes such as Small, Medium, Large, and X-Large. Some teams prefer to use Coffee Cup sizes such as Tall, Short, and Grande. Finally, some teams like to use numbers from the Fibonacci series. These alternative units are converted into a Story Point value. Regardless of the type of unit which you use to represent Story Points, the goal is the same. Instead of attempting to estimate a Story in hours (which is doomed to failure), you use a much less fine-grained measure of work. A developer team is much more likely to be able to estimate that a Story is Small or X-Large than the exact number of hours required to complete the story. So you can think of Story Points as a compromise between the needs of the Product Owner and the developer team. When a Sprint starts, the developer team devotes more time to thinking about the Stories in a Sprint and the developer team breaks the Stories into Tasks. In Scrum, you estimate the work required to complete a Story by using Story Points and you estimate the work required to complete a task by using hours. The difference between Stories and Tasks is that you don’t create a task until you are just about ready to start working on a task. A task is something that you should be able to create within a day, so you have a much better chance of providing an accurate estimate of the work required to complete a task than a story. Burndown Charts In Scrum, you use Burndown charts to represent the remaining work on a project. You use Release Burndown charts to represent the overall remaining work for a project and you use Sprint Burndown charts to represent the overall remaining work for a particular Sprint. You create a Release Burndown chart by calculating the remaining number of uncompleted Story Points for the entire Product Backlog every day. The vertical axis represents Story Points and the horizontal axis represents time. A Sprint Burndown chart is similar to a Release Burndown chart, but it focuses on the remaining work for a particular Sprint. There are two different types of Sprint Burndown charts. You can either represent the remaining work in a Sprint with Story Points or with task hours (the following image, taken from Wikipedia, uses hours). When each Product Backlog Story is completed, the Release Burndown chart slopes down. When each Story or task is completed, the Sprint Burndown chart slopes down. Burndown charts typically do not always slope down over time. As new work is added to the Product Backlog, the Release Burndown chart slopes up. If new tasks are discovered during a Sprint, the Sprint Burndown chart will also slope up. The purpose of a Burndown chart is to give you a way to track team progress over time. If, halfway through a Sprint, the Sprint Burndown chart is still climbing a hill then you know that you are in trouble. Team Velocity Stakeholders in a project always want more work done faster. For example, the Product Owner for the e-commerce site wants the website to launch before tomorrow. Developers tend to be overly optimistic. Rarely do developers acknowledge the physical limitations of reality. So Project stakeholders and the developer team often collude to delude themselves about how much work can be done and how quickly. Too many software projects begin in a state of optimism and end in frustration as deadlines zoom by. In Scrum, this problem is overcome by calculating a number called the Team Velocity. The Team Velocity is a measure of the average number of Story Points which a team has completed in previous Sprints. Knowing the Team Velocity is important during the Sprint Planning meeting when the Product Owner and the developer team work together to determine the number of stories which can be completed in the next Sprint. If you know the Team Velocity then you can avoid committing to do more work than the team has been able to accomplish in the past, and your team is much more likely to complete all of the work required for the next Sprint. Scrum Master There are three roles in Scrum: the Product Owner, the developer team, and the Scrum Master. I’v e already discussed the Product Owner. The Product Owner is the one and only person who maintains the Product Backlog and prioritizes the stories. I’ve also described the role of the developer team. The members of the developer team do the work of implementing the stories by breaking the stories into tasks. The final role, which I have not discussed, is the role of the Scrum Master. The Scrum Master is responsible for ensuring that the team is following the Scrum process. For example, the Scrum Master is responsible for making sure that there is a Daily Scrum meeting and that everyone answers the standard three questions. The Scrum Master is also responsible for removing (non-technical) impediments which the team might encounter. For example, if the team cannot start work until everyone installs the latest version of Microsoft Visual Studio then the Scrum Master has the responsibility of working with management to get the latest version of Visual Studio as quickly as possible. The Scrum Master can be a member of the developer team. Furthermore, different people can take on the role of the Scrum Master over time. The Scrum Master, however, cannot be the same person as the Product Owner. Using SonicAgile SonicAgile (SonicAgile.com) is an online tool which you can use to manage your projects using Scrum. You can use the SonicAgile Product Backlog to create a prioritized list of stories. You can estimate the size of the Stories using different Story Point units such as Shirt Sizes and Coffee Cup sizes. You can use SonicAgile during the Sprint Planning meeting to select the Stories that you want to complete during a particular Sprint. You can configure Sprints to be any length of time. SonicAgile calculates Team Velocity automatically and displays a warning when you add too many stories to a Sprint. In other words, it warns you when it thinks you are overcommitting in a Sprint. SonicAgile also includes a Scrumboard which displays the list of Stories selected for a Sprint and the tasks associated with each story. You can drag tasks from one task state to another. Finally, SonicAgile enables you to generate Release Burndown and Sprint Burndown charts. You can use these charts to view the progress of your team. To learn more about SonicAgile, visit SonicAgile.com. Summary In this post, I described many of the basic concepts of Scrum. You learned how a Product Owner uses a Product Backlog to create a prioritized list of tasks. I explained why work is completed in Sprints so the developer team can be more productive. I also explained how a developer team uses the daily scrum to coordinate their work. You learned how the developer team uses a Scrumboard to see, at a glance, who is working on what and the state of each task. I also discussed Burndown charts. You learned how you can use both Release and Sprint Burndown charts to track team progress in completing a project. Finally, I described the crucial role of the Scrum Master – the person who is responsible for ensuring that the rules of Scrum are being followed. My goal was not to describe all of the concepts of Scrum. This post was intended to be an introductory overview. For a comprehensive explanation of Scrum, I recommend reading Ken Schwaber’s book Agile Project Management with Scrum: http://www.amazon.com/Agile-Project-Management-Microsoft-Professional/dp/073561993X/ref=la_B001H6ODMC_1_1?ie=UTF8&qid=1345224000&sr=1-1

  • Azure &ndash; Part 6 &ndash; Blob Storage Service

    - by Shaun
    When migrate your application onto the Azure one of the biggest concern would be the external files. In the original way we understood and ensure which machine and folder our application (website or web service) is located in. So that we can use the MapPath or some other methods to read and write the external files for example the images, text files or the xml files, etc. But things have been changed when we deploy them on Azure. Azure is not a server, or a single machine, it’s a set of virtual server machine running under the Azure OS. And even worse, your application might be moved between thses machines. So it’s impossible to read or write the external files on Azure. In order to resolve this issue the Windows Azure provides another storage serviec – Blob, for us. Different to the table service, the blob serivce is to be used to store text and binary data rather than the structured data. It provides two types of blobs: Block Blobs and Page Blobs. Block Blobs are optimized for streaming. They are comprised of blocks, each of which is identified by a block ID and each block can be a maximum of 4 MB in size. Page Blobs are are optimized for random read/write operations and provide the ability to write to a range of bytes in a blob. They are a collection of pages. The maximum size for a page blob is 1 TB.   In the managed library the Azure SDK allows us to communicate with the blobs through these classes CloudBlobClient, CloudBlobContainer, CloudBlockBlob and the CloudPageBlob. Similar with the table service managed library, the CloudBlobClient allows us to reach the blob service by passing our storage account information and also responsible for creating the blob container is not exist. Then from the CloudBlobContainer we can save or load the block blobs and page blobs into the CloudBlockBlob and the CloudPageBlob classes.   Let’s improve our exmaple in the previous posts – add a service method allows the user to upload the logo image. In the server side I created a method name UploadLogo with 2 parameters: email and image. Then I created the storage account from the config file. I also add the validation to ensure that the email passed in is valid. 1: var storageAccount = CloudStorageAccount.FromConfigurationSetting("DataConnectionString"); 2: var accountContext = new DynamicDataContext<Account>(storageAccount); 3:  4: // validation 5: var accountNumber = accountContext.Load() 6: .Where(a => a.Email == email) 7: .ToList() 8: .Count; 9: if (accountNumber <= 0) 10: { 11: throw new ApplicationException(string.Format("Cannot find the account with the email {0}.", email)); 12: } Then there are three steps for saving the image into the blob service. First alike the table service I created the container with a unique name and create it if it’s not exist. 1: // create the blob container for account logos if not exist 2: CloudBlobClient blobStorage = storageAccount.CreateCloudBlobClient(); 3: CloudBlobContainer container = blobStorage.GetContainerReference("account-logo"); 4: container.CreateIfNotExist(); Then, since in this example I will just send the blob access URL back to the client so I need to open the read permission on that container. 1: // configure blob container for public access 2: BlobContainerPermissions permissions = container.GetPermissions(); 3: permissions.PublicAccess = BlobContainerPublicAccessType.Container; 4: container.SetPermissions(permissions); And at the end I combine the blob resource name from the input file name and Guid, and then save it to the block blob by using the UploadByteArray method. Finally I returned the URL of this blob back to the client side. 1: // save the blob into the blob service 2: string uniqueBlobName = string.Format("{0}_{1}.jpg", email, Guid.NewGuid().ToString()); 3: CloudBlockBlob blob = container.GetBlockBlobReference(uniqueBlobName); 4: blob.UploadByteArray(image); 5:  6: return blob.Uri.ToString(); Let’s update a bit on the client side application and see the result. Here I just use my simple console application to let the user input the email and the file name of the image. If it’s OK it will show the URL of the blob on the server side so that we can see it through the web browser. Then we can see the logo I’ve just uploaded through the URL here. You may notice that the blob URL was based on the container name and the blob unique name. In the document of the Azure SDK there’s a page for the rule of naming them, but I think the simple rule would be – they must be valid as an URL address. So that you cannot name the container with dot or slash as it will break the ADO.Data Service routing rule. For exmaple if you named the blob container as Account.Logo then it will throw an exception says 400 Bad Request.   Summary In this short entity I covered the simple usage of the blob service to save the images onto Azure. Since the Azure platform does not support the file system we have to migrate our code for reading/writing files to the blob service before deploy it to Azure. In order to reducing this effort Microsoft provided a new approch named Drive, which allows us read and write the NTFS files just likes what we did before. It’s built up on the blob serivce but more properly for files accessing.

  • Building the Elusive Windows Phone Panorama Control

    When the Windows Phone 7 Developer SDK was released a couple of weeks ago at MIX10 many people noticed the SDK doesnt include a template for a Panorama control.   Here at Clarity we decided to build our own Panorama control for use in some of our prototypes and I figured I would share what we came up with. There have been a couple of implementations of the Panorama control making their way through the interwebs, but I didnt think any of them really nailed the experience that is shown in the simulation videos.   One of the key design principals in the UX Guide for Windows Phone 7 is the use of motion.  The WP7 OS is fairly stripped of extraneous design elements and makes heavy use of typography and motion to give users the necessary visual cues.  Subtle animations and wide layouts help give the user a sense of fluidity and consistency across the phone experience.  When building the panorama control I was fairly meticulous in recreating the motion as shown in the videos.  The effect that is shown in the application hubs of the phone is known as a Parallax Scrolling effect.  This this pseudo-3D technique has been around in the computer graphics world for quite some time. In essence, the background images move slower than foreground images, creating an illusion of depth in 2D.  Here is an example of the traditional use: http://www.mauriciostudio.com/.  One of the animation gems I've learned while building interactive software is the follow animation.  The premise is straightforward: instead of translating content 1:1 with the interaction point, let the content catch up to the mouse or finger.  The difference is subtle, but the impact on the smoothness of the interaction is huge.  That said, it became the foundation of how I achieved the effect shown below.   Source Code Available HERE Before I briefly describe the approach I took in creating this control..and Ill add some **asterisks ** to the code below as my coding skills arent up to snuff with the rest of my colleagues.  This code is meant to be an interpretation of the WP7 panorama control and is not intended to be used in a production application.  1.  Layout the XAML The UI consists of three main components :  The background image, the Title, and the Content.  You can imagine each  these UI Elements existing on their own plane with a corresponding Translate Transform to create the Parallax effect.  2.  Storyboards + Procedural Animations = Sexy As I mentioned above, creating a fluid experience was at the top of my priorities while building this control.  To recreate the smooth scroll effect shown in the video we need to add some place holder storyboards that we can manipulate in code to simulate the inertia and snapping.  Using the easing functions built into Silverlight helps create a very pleasant interaction.    3.  Handle the Manipulation Events With Silverlight 3 we have some new touch event handlers.  The new Manipulation events makes handling the interactivity pretty straight forward.  There are two event handlers that need to be hooked up to enable the dragging and motion effects: the ManipulationDelta event :  (the most relevant code is highlighted in pink) Here we are doing some simple math with the Manipulation Deltas and setting the TO values of the animations appropriately. Modifying the storyboards dynamically in code helps to create a natural feel.something that cant easily be done with storyboards alone.   And secondly, the ManipulationCompleted event:  Here we take the Final Velocities from the Manipulation Completed Event and apply them to the Storyboards to create the snapping and scrolling effects.  Most of this code is determining what the next position of the viewport will be.  The interesting part (shown in pink) is determining the duration of the animation based on the calculated velocity of the flick gesture.  By using velocity as a variable in determining the duration of the animation we can produce a slow animation for a soft flick and a fast animation for a strong flick. Challenges to the Reader There are a couple of things I didnt have time to implement into this control.  And I would love to see other WPF/Silverlight approaches.  1.  A good mechanism for deciphering when the user is manipulating the content within the panorama control and the panorama itself.   In other words, being able to accurately determine what is a flick and what is click. 2.  Dynamically Sizing the panorama control based on the width of its content.  Right now each control panel is 400px, ideally the Panel items would be measured and then panorama control would update its size accordingly.  3.  Background and content wrapping.  The WP7 UX guidelines specify that the content and background should wrap at the end of the list.  In my code I restrict the drag at the ends of the list (like the iPhone).  It would be interesting to see how this would effect the scroll experience.     Well, Its been fun building this control and if you use it Id love to know what you think.  You can download the Source HERE or from the Expression Gallery  Erik Klimczak  | [email protected] | twitter.com/eklimczDid you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

  • 2010 Collaboration Summit Impressions

    - by Elena Zannoni
    It's a bit late, but there you have it anyway. April 14 to 16 I attended the Linux Foundation Collaboration Summit in SFO. I was running two tracks, one on tracing and one on tools. You can see the tracks and the slides here: http://events.linuxfoundation.org/events/collaboration-summit/slides I was pretty busy both days, Thursday with a whole day tracing track, Friday with a half day toolchain track. The sessions were well attended, the rooms were full, with people spilling in the hallways. Some new things were presented, like Kernelshark, by Steve Rostedt, a GUI (yes, believe it or not, a GUI) written in GTK. It is very nice, showing a timeline for traced kernel events, and you can zoom in and filter at will. It works on the latest kernels, and it requires some new things/fixes in GTK. I don't recall exactly what version of GTK though. Dominique Toupin from Ericsson presented something about user requirements for tracing. Mostly though about who's who in the embedded world, and eclipse. Masami and Mathieu presented an update on their work. See their slides. The interesting thing to me was of course the new version of uprobes w/o underlying utrace presented by Jim Keniston. At the end of the session we had a discussion about the future of utrace. Roland wasn't there, butTom Tromey (also from RedHat) collected the feedback. Basically we are at a standstill now that utrace has been rejected yet again. There wasn't much advise that anybody could give, except jokingly, we decided that the only way in is to make it a part of perf events. There needs to be another refactoring, but most of all, this "killer app" that would be enabled because of utrace hasn't materialized yet. We think that having a good debugging story on Linux is enough of a killer app, for instance allowing multiple tracers, and not relying on SIGCHLD etc. I think this wasn't completely clear to the kernel community. Trying to achieve debugging via a gdb stub inside the kernel interfacing to utrace and that is controlled via the gdb remote protocol also lost its appeal (thankfully, since the gdb remote protocol is archaic). Somebody would have to be creative in how to submit utrace. It doesn't have to be called utrace (it was really a random choice, for lack of a letter that was not already used in front of the word "trace"). So basically, I think the ideas behind utrace are sound, and the necessity of a new interface is acknowledged. But I believe the integration/submission process with the kernel folks has to restart from scratch, clean slate. We'll see. There are many conferences and meetings coming up in the near future where things can be discussed further. On the second day, Friday, we had the tools talks. It was interesting to observe the more "kernel" oriented people's behavior towards the gcc etc community. The first talk was by Mark Mitchell, about Gcc and its new plugin architecture. After that, Paolo talked about the new C++1x standard, which will be finalized in 2011. Many features are already implemented in the libstdc++ library and gcc and usable today. We had a few minutes (really, the half day track was quite short) where Bradley Kuhn from the Software Freedom Law Center explained the GPLv3 exception for gcc (due to the new gcc plugin architecture and the availability of the intermediate results from the compilation, which is a new thing). I will not try to explain, but basically you cannot take the result of the preprocessing and then use that in your own proprietary compiler. After, we had a talk by Ian Taylor about the new Gold linker. One good thing in that area is that they are trying to make gold the new default linker (for instance Fedora will use gold as the distro linker). However gold is very different from binutils' old linker. It doesn't use a linker script, for instance. The kernel has been linked with gold many times as an exercise (the ground work was done by Kris Van Hees), but this needs to be constantly tested/monitored because the kernel linker script is very complex, and uses esoteric features (Wenji is now monitoring that each kernel RC can be built with gold). It was positive that people are now aware of gold and the need for it to be ported to more architectures. It seems that the porting is very easy, with little arch dependent code. Finally Tom Tromey presented about gdb and the archer project. Archer is a development branch of gdb mostly done by RedHat, where they are focusing on better c++ printing, c++ expression parsing, and plugins. The archer work is merged regularly in the gdb mainline. In general it was a good conference. I did miss most of the first day, because that's when I flew in. But I caught a couple of talks. Nothing earth shattering, except for Google giving each person registered a free Android phone. Yey.

  • SharePoint Saturday Michigan 2010 Recap, Slides, and Photos

    - by Brian Jackett
    This past weekend I attended SharePoint Saturday Michigan (SPSMI) in Ann Arbor, Michigan.  For those unfamiliar, SharePoint Saturday is a community driven event where various speakers gather to present at a FREE conference on all topics related to SharePoint.  This made my third SharePoint Saturday attended and second I’ve spoken at.  I believe today it was announced that about 210 people total attended the event.  I was very happy with the turnout, especially the ratio of male to female attendees.  Typically with computer related conferences the ratio leans towards more males attending, but both Peter Serzo (one of conference organizers) and I both commented to each other that at the end of the day it appeared to be close to 40% women in the crowd.  So here’s my recap of the weekend. Arrival     Friday afternoon I drove up from Columbus, OH to Ann Arbor, MI and arrived around 4pm.  I was attempting to avoid the rush hour traffic and construction backups.  Turned out to be a good idea because other speakers coming up Friday got stuck on a highway which literally closed down in both directions due to a bad accident.  I was talking my friend Sean McDonough through the highway closing and this was the first time I had seen a solid black traffic line on Google Maps.  Most of us are familiar with Green, Yellow, and Red, but this line was black if that tells you how bad it got. Speaker “Dinner”     Fast forward a few hours and it was time for the speaker “dinner.”  I put “dinner” in quotes because with this night alone SPSMI set a new bar for nicest and most extravagant speaker appreciation events for SharePoint Saturday.  By tapping into some very influential contacts, the conference organizers were able to provide a truck limo (yep you heard right) with refreshments, access to an underground suite at the Palace of Auburn Hills, and courtside tickets to see the Detroit Pistons play that night.  Being a Michigan native I have to say that I was absolutely floored by this experience and very thankful to our conference organizers Peter, Sebastian, and Jesse along with Trillium Teamologies. Sessions     The actual conference started Saturday morning at 9am with the keynote by Rob Collie who is the Microsoft program manager for PowerPivot.  The day continued and I attended the following sessions: Mike Watson (@mikewat) – “SharePoint 2010 Fight Night: Devs vs. Admins” Karl Swedeberg (@kswedberg) – “A Walk on the Client Side with jQuery“ [my session] Brian Jackett (@briantjackett) - “Real World Deployment of SharePoint 2007 Solutions” Jeff Willinger (@jwillie) - “Social Computing and Collaboration Inside and Outside the 4 Walls” Paul Schaeflein (@paulschaeflein) – “PowerShell for the SharePoint Developer” My Presentation     I had a great time presenting my session on Deploying SharePoint 2007 Solutions, but it wasn’t without its fair share of technical issues.  As my session was right after lunch I came in to my room 10 mins early to set up my laptop, slides, and demos.  As a quick background note, a few months ago I got an upgraded laptop from my company Sogeti and have been dual booting it between XP (factory installed) and Windows Server 2008 R2 w/ Hyper-V.  As such I had prepared all of my demo virtual machines to run under Hyper-V.  About 3 minutes before my session was scheduled to start though it became apparent that I did not have the correct display drivers to connect Windows Server 2008 R2 to the projector…     As you can imagine this was a slight cause for concern as I was potentially going to be unable to give my presentation.  Luckily for me I usually prepare for such unforeseen issues and had my presentation and some spare VMs that would run on XP on my external hard drive.  Knowing this I rebooted my machine into XP and began my presentation without slides until about 5 mins into the session when everything was up and running on XP.  Despite this being the first time I gave this presentation I have to say it was one of my favorites I’ve given so far.  The audience was very engaged in the session and I received some great, positive feedback afterwards.  Thanks to all who attended my session, I appreciate it very much. Link to Presentation Files     For those of you who attended my session and would like my slides or demo PowerShell scripts they can be found on my SkyDrive at the link below.  Also, if you have a few minutes and wouldn’t mind rating my session I have this session posted on SpeakerRate.  As speakers we always appreciate any and all feedback attendees offer, so thank you if you are able to provide any. SkyDrive folder with session files Rate my SharePoint 2007 Solutions session   Picture Albums     For everyone else, here are my pictures from the weekend.  The first link is to my FaceBook album which will have tagging (recommend this one.)  The second is to my Live album if you care for higher resolution images. http://www.facebook.com/album.php?aid=2154482&id=21905041&l=a3fb72ee8c View Full Album Conclusion     A big thank you goes out to all of the organizers, speakers, sponsors, and attendees of SPSMI.  As I’ve said so many times, without each and every one of you these events wouldn’t be possible.  I thoroughly enjoyed this trip back to my home state and presenting a new session.  For those interested in my upcoming schedule I will be giving two sessions on PowerShell at SharePoint Saturday Charlotte in April, helping plan Stir Trek: Iron Man Edition in May, and I’m submitting sessions to Day of .Net Ann Arbor in May as well.  Beyond that I haven’t planned out any travels.  Thanks for reading my recap.  Look forward to more technical posts now that I have a short break in conferences.         -Frog Out   links: Michigan image

  • Installing SOA Suite 11.1.1.3

    - by James Taylor
    With the release of Oracle SOA Suite 11.1.1.3 last week (28 April 2010) I thought I would attempt to implement a complete SOA Environment with SOA Suite, BPM and OSB on the WLS infrastructure. One major point of difference with the 11.1.1.3 is that is is released as a point release so you must have 11.1.1.2 installed first, then upgrade to 11.1.1.3. This post is performing the upgrade on Linux, if upgrading on windows you will need to substitute the directories and files accordingly. This post assumes that you have SOA Suite 11.1.1.2 installed already. 1. Download 11.1.1.3 software from the following site: http://www.oracle.com/technology/software/products/middleware/htdocs/fmw_11_download.html WLS 11.1.1.3   RCU 11.1.1.3 SOA Suite 11.1.1.3 OSB 11.1.1.3 Copy files to a staging area. For the purpose of this document the staging area is: /u01/stage  2. Shutdown your existing SOA Suite 11.1.1.2 environment 3. Execute the WLS 11.1.1.3 install from the stage directory. wls1033_linux32.bin 4. Choose the existing 11.1.1.2 Middleware Home 5. Ignore the security update notification 6. Accept the default products to be upgraded. 7. Upgrade of WebLogic has been completed   8. Upgrade the SOA Suite database schemas using the RCU utility. Unzip the RCU utility into the staging area and run the install ./u01/stage/rcuHome/bin/rcu 9. Drop the existing Repository and provide connection details 9. Install SOA Suite patch set 11.1.1.3. Unzip the SOA Suite patchset and execute the runInstaller with the following command. ./u01/stage/Disk1/runInstaller –jreLoc $MW_HOME/jdk160_18/jre 10. Choose the existing 11.1.1.2 middleware home 11. Start Install 12. Your SOA Suite Install should now be completed. Now we need to update the database repository. Login to SQLPlus as sysdba and execute the following command. SELECT version, status FROM schema_version_registry where owner = 'DEV_SOAINFRA'; the result should be similar to this: VERSION                        STATUS      OWNER ------------------------------ ----------- ------------------------------ 11.1.1.2.0                     VALID       DEV_SOAINFRA As you can see the version if these repositories are still at 11.1.1.2. 13. To upgrade these versions you have 2 options. 1 install via RCU, but this will remove any existing services. The second option is to use the Patch Set Assistant. From the $MW_HOME directory run the following command ./Oracle_SOA1/bin/psa -dbType Oracle -dbConnectString 'localhost:1521:xe' -dbaUserName sys -schemaUserName DEV_SOAINFRA 14. Install OSB. For the OSB install I did not install the IDE, or the Examples. run the runInstaller from the command line, unzip the OSB download to the stage area. ./u01/stage/osb/Disk1/runInstaller –jreLoc $MW_HOME/jdk160_18/jre 15. Choose Custom Install NOT to install the IDE (Eclipse) or Examples. 16. Unselect the, Examples and IDE checkboxes. 17. Accept the defaults and start installing. 18. Once the install has been completed configure the domain by running the Configuration Wizard. $MW_HOME/oracle_common/common/bin/config.sh You can create a new domain. In this document I will extend the soa_domain. 19. Select the following from the check list. I have selected the BPM Suite, this is unrelated to OSB but wanted it for my development purposes. To use this functionality additional license are required. 20. Configure the database connectivity. 21. Configure the database connectivity for the OSB schema. 22. Accept the defaults if installing on standard machine, if you require a cluster or advanced configuration then choose the option for you. 23. Upgrade is complete and OSB has been installed. Now you can start your environment.

  • adding slugs to the URLs afterwards

    - by altuure
    we have a website for last 5 months and we did not used slug at bottom level elements so urls was like /apps/webmasters/badges/1100 would it make sense to add name to the URL after that point and redirect to the new ones ? I am interested in building more search terms. and increase page ranks ..... /apps/webmasters/badges/1100 - redirect and served at /apps/webmasters/badges/1100-supporter Or should I keep old URLs as is and create new urls with slugs. I would also appreciate some advice on shared urls on facebook or on twitter in those cases. Thanks in advance...

  • Introducing Microsoft SQL Server 2008 R2 - Business Intelligence Samples

    - by smisner
    On April 14, 2010, Microsoft Press (blog | twitter) released my latest book, co-authored with Ross Mistry (twitter), as a free ebook download - Introducing Microsoft SQL Server 2008 R2. As the title implies, this ebook is an introduction to the latest SQL Server release. Although you'll find a comprehensive review of the product's features in this book, you will not find the step-by-step details that are typical in my other books. For those readers who are interested in a more interactive learning experience, I have created two samples file for download: IntroSQLServer2008R2Samples project Sales Analysis workbook Here's a recap of the business intelligence chapters and the samples I used to generate the screen shots by chapter: Chapter 6: Scalable Data Warehousing covers a new edition of SQL Server, Parallel Data Warehouse. Understandably, Microsoft did not ship me the software and hardware to set up my own Parallel Data Warehouse environment for testing purposes and consequently you won't see any screenshots in this chapter. I received a lot of information and a lot of help from the product team during the development of this chapter to ensure its technical accuracy. Chapter 7: Master Data Services is a new component in SQL Server. After you install Master Data Services (MDS), which is a separate installation from SQL Server although it's found on the same media, you can install sample models to explore (which is what I did to create screenshots for the book). To do this, you deploying packages found at \Program Files\Microsoft SQL Server\Master Data Services\Samples\Packages. You will first need to use the Configuration Manager (in the Microsoft SQL Server 2008 R2\Master Data Services program group) to create a database and a Web application for MDS. Then when you launch the application, you'll see a Getting Started page which has a Deploy Sample Data link that you can use to deploy any of the sample packages. Chapter 8: Complex Event Processing is an introduction to another new component, StreamInsight. This topic was way too large to cover in-depth in a single chapter, so I focused on information such as architecture, development models, and an overview of the key sections of code you'll need to develop for your own applications. StreamInsight is an engine that operates on data in-flight and as such has no user interface that I could include in the book as screenshots. The November CTP version of SQL Server 2008 R2 included code samples as part of the installation, but these are not the official samples that will eventually be available in Codeplex. At the time of this writing, the samples are not yet published. Chapter 9: Reporting Services Enhancements provides an overview of all the changes to Reporting Services in SQL Server 2008 R2, and there are many! In previous posts, I shared more details than you'll find in the book about new functions (Lookup, MultiLookup, and LookupSet), properties for page numbering, and the new global variable RenderFormat. I will confess that I didn't use actual data in the book for my discussion on the Lookup functions, but I did create real reports for the blog posts and will upload those separately. For the other screenshots and examples in the book, I have created the IntroSQLServer2008R2Samples project for you to download. To preview these reports in Business Intelligence Development Studio, you must have the AdventureWorksDW2008R2 database installed, and you must download and install SQL Server 2008 R2. For the map report, you must execute the PopulationData.sql script that I included in the samples file to add a table to the AdventureWorksDW2008R2 database. The IntroSQLServer2008R2Samples project includes the following files: 01_AggregateOfAggregates.rdl to illustrate the use of embedded aggregate functions 02_RenderFormatAndPaging.rdl to illustrate the use of page break properties (Disabled, ResetPageNumber), the PageName property, and the RenderFormat global variable 03_DataSynchronization.rdl to illustrate the use of the DomainScope property 04_TextboxOrientation.rdl to illustrate the use of the WritingMode property 05_DataBar.rdl 06_Sparklines.rdl 07_Indicators.rdl 08_Map.rdl to illustrate a simple analytical map that uses color to show population counts by state PopulationData.sql to provide the data necessary for the map report Chapter 10: Self-Service Analysis with PowerPivot introduces two new components to the Microsoft BI stack, PowerPivot for Excel and PowerPivot for SharePoint, which you can learn more about at the PowerPivot site. To produce the screenshots for this chapter, I created the Sales Analysis workbook which you can download (although you must have Excel 2010 and the PowerPivot for Excel add-in installed to explore it fully). It's a rather simple workbook because space in the book did not permit a complete exploration of all the wonderful things you can do with PowerPivot. I used a tutorial that was available with the CTP version as a basis for the report so it might look familiar if you've already started learning about PowerPivot. In future posts, I'll continue exploring the new features in greater detail. If there's any special requests, please let me know!
