    - by mary
    hello, I am working on the chart project in asp.net mvc. i used followinf code to genrate the chart on the controller. Chart chart1 = new Chart(); chart1.Height = 296; chart1.Width = 412; chart1.ImageType = ChartImageType.Png; Title title = chart1.Titles.Add("Main"); Series series1 = chart1.Series.Add("series1"); chart1.Series["series1"].Points.DataBindXY(xvalues, yvalues); chart1.Series["series1"].ChartType = SeriesChartType.Column ; ChartArea chartArea = chart1.ChartAreas.Add("Default"); chartArea.Area3DStyle.Enable3D = false ; MemoryStream ms = new MemoryStream(); chart1.SaveImage(ms); return File(ms.GetBuffer(), @"image/png"); and on the view page i am calling it as when i am running it on local pc its working fine but when i deployed it on server then chart is not displaying instated alernate text is showing. and its not working on another pc also. plz if anyone can know the reson tell me. thank you.

  • How to change the view angle and label value of a chart .NET C#

    - by George
    Short Description I am using charts for a specific application where i need to change the view angle of the rendered 3D Pie chart and value of automatic labels from pie label names to corresponding pie values. This how the chart looks: Initialization This is how i initialize it: Dictionary<string, decimal> secondPersonsWithValues = HistoryModel.getSecondPersonWithValues(); decimal[] yValues = new decimal[secondPersonsWithValues.Values.Count]; //VALUES string[] xValues = new string[secondPersonsWithValues.Keys.Count]; //LABELS secondPersonsWithValues.Keys.CopyTo(xValues, 0); secondPersonsWithValues.Values.CopyTo(yValues, 0); incomeExpenseChart.Series["Default"].ChartType = System.Windows.Forms.DataVisualization.Charting.SeriesChartType.Pie; incomeExpenseChart.Series["Default"].Points.DataBindXY(xValues, yValues); incomeExpenseChart.ChartAreas["Default"].Area3DStyle.Enable3D = true; incomeExpenseChart.Series["Default"].CustomProperties = "PieLabelStyle=Outside"; incomeExpenseChart.Legends["Default"].Enabled = true; incomeExpenseChart.ChartAreas["Default"].Area3DStyle.LightStyle = System.Windows.Forms.DataVisualization.Charting.LightStyle.Realistic; incomeExpenseChart.Series["Default"]["PieDrawingStyle"] = "SoftEdge"; Basically i am querying data from database using the HistoryModel.getSecondPersonWithValues(); to get pairs as Dictionary<string, decimal> where key is the person and value is ammount. Problem #1 What i need is to be able to change the marked labels from person names to the ammounts or add another label of ammounts with the same colors (See Image). Problem #2 Another problem is that i need to change the view angle of 3D Pie chart. Maybe it's very simple and I just don't know the needed property or maybe i need to override some paint event. Either ways any kind of ways would be appriciated. Thanks in advance George.

  • ASP Chart Control doesn't ahow anything

    - by Esabe
    Hi everyone, I am using the new ASP control "Chart", but I have some problems with it: I can't see anything when I execute the aspx. The data is binded to a ObjectDataSource, like this: <asp:Chart ID="RcrBufferChart" runat="server" Visible="true" DataSourceID="RcrBufferSizeODS" BackColor="WhiteSmoke" BackGradientStyle="TopBottom" BackSecondaryColor="White" Palette="BrightPastel" BorderDashStyle="Solid" BorderColor="26, 59, 105" Height="583px" Width="1159px" > <borderskin skinstyle="Emboss"></borderskin> <series> <asp:series Name="Series1" ChartType="Spline" ShadowColor="Black" BorderColor="180, 26, 59, 105" Color="224, 64, 10" IsValueShownAsLabel="True" XValueMember="CreationDate" XValueType="DateTime" YValueMembers="Size" YValueType="Double"></asp:series> </series> <chartareas> <asp:ChartArea Name="ChartArea1"> <AxisY Title="Tamaño RCR sin enviar"> </AxisY> <AxisX Title="Fecha"> </AxisX> </asp:ChartArea> </chartareas> </asp:Chart> <asp:ObjectDataSource ID="RcrBufferSizeODS" runat="server" SelectMethod="GetByAppliance" TypeName="Esabe.Grazalema.Business.RcrBufferSizes"> <SelectParameters> <asp:QueryStringParameter Name="serialNumber" QueryStringField="SerialNumber" Type="String" /> </SelectParameters> </asp:ObjectDataSource> but the result I get is the following: Does anyone know why it isn't showing anything?

  • R Random Data Sets within loops

    - by jugossery
    Here is what I want to do: I have a time series data frame with let us say 100 time-series of length 600 - each in one column of the data frame. I want to pick up 4 of the time-series randomly and then assign them random weights that sum up to one (ie 0.1, 0.5, 0.3, 0.1). Using those I want to compute the mean of the sum of the 4 weighted time series variables (e.g. convex combination). I want to do this let us say 100k times and store each result in the form ts1.name, ts2.name, ts3.name, ts4.name, weight1, weight2, weight3, weight4, mean so that I get a 9*100k df. I tried some things already but R is very bad with loops and I know vector oriented solutions are better because of R design. Thanks Here is what I did and I know it is horrible The df is in the form v1,v2,v2.....v100 1,5,6,.......9 2,4,6,.......10 3,5,8,.......6 2,2,8,.......2 etc e=NULL for (x in 1:100000) { s=sample(1:100,4)#pick 4 variables randomly a=sample(seq(0,1,0.01),1) b=sample(seq(0,1-a,0.01),1) c=sample(seq(0,(1-a-b),0.01),1) d=1-a-b-c e=c(a,b,c,d)#4 random weights average=mean(timeseries.df[,s]%*%t(e)) e=rbind(e,s,average)#in the end i get the 9*100k df } The procedure runs way to slow. EDIT: Thanks for the help i had,i am not used to think R and i am not very used to translate every problem into a matrix algebra equation which is what you need in R. Then the problem becomes a little bit complex if i want to calculate the standard deviation. i need the covariance matrix and i am not sure i can if/how i can pick random elements for each sample from the original timeseries.df covariance matrix then compute the sample variance (t(sampleweights)%*%sample_cov.mat%*%sampleweights) to get in the end the ts.weighted_standard_dev matrix Last question what is the best way to proceed if i want to bootstrap the original df x times and then apply the same computations to test the robustness of my datas thanks

  • Try out Windows Phone 7 on your PC today

    - by Matthew Guay
    Anticipation has been building for the new Windows Phone 7 Series ever since Microsoft unveiled it at the Mobile World Congress in February.  Now, thanks to free developer tools, you can get a first-hand experience of the basic Windows Phone 7 Series devices on your PC. Windows Phone 7 Series represents a huge change in the mobile field for Microsoft, bringing the acclaimed Zune HD UI to an innovative phone platform.  Windows Mobile has often been criticized for being behind other Smartphone platforms, but Microsoft seeks to regain the lead with this new upcoming release.  A platform must have developers behind it to be useful, so they have released a full set of free development tools so anyone can make apps for it today.  Or, if you simply want to play with Windows Phone 7, you can use the included emulator to try out the new Metro UI.  Here’s how to do this today on your Vista or 7 computer. Please note: These tools are a Customer Technology Preview release, so only install them if you’re comfortable using pre-release software. Getting Started First, download the Windows Phone Developer Tools CTP (link below), and run the installer.  This will install the Customer Technology Preview (CTP) versions of Visual Studio 2010 Express for Windows Phone, Windows Phone Emulator, Silverlight for Windows Phone, and XNA 4.0 Game Studio on your computer, all of which are required and cannot be installed individually. Accept the license agreement when prompted. Click “Install Now” to install the tools you need.  The only setup customization option is where to save the files, so choose Customize if you need to do so. Setup will now automatically download and install the components you need, and will additionally download either 32 or 64 bit programs depending on your operating system. About halfway thorough the installation, you’ll be prompted to reboot your system.  Once your computer is rebooted, setup will automatically resume without further input.   When setup is finished, click “Run the Product Now” to get started. Running Windows Phone 7 on your PC Now that you’ve got the Windows Phone Developer tools installed, it’s time to get the Windows Phone emulator running.  If you clicked “Run the Product Now” when the setup finished, Visual Studio 2010 Express for Windows Phone should have already started.   If not, simply enter “visual studio” in your start menu search and select “Microsoft Visual Studio 2010 Express for Windows Phone”. Now, to run the Windows Phone 7 emulator, we have to test an application.  So, even if you don’t know how to program, we can open a phone application template, and then test it to run the emulator.  First, click New Project on the left hand side of the front page. Any of the application templates would work for this, but here let’s select “Windows Phone Application”, and then click Ok. Here’s your new application template, which already contains the basic phone application framework.  This is where you’d start if you want to develop a Windows Phone app, but for now we just want to see Windows Phone 7 in action. So, to run the emulator, click Debug in the menu and then select Start Debugging. Your new application will launch inside the Windows Phone 7 Series emulator.  The default template doesn’t give us much, but it does show an example application running in Windows Phone 7.   Exploring Windows Phone 7 Click the Windows button on the emulator to go to the home screen.  Notice the Zune HD-like transition animation.  The emulator only includes Internet Explorer, your test application, and a few settings. Click the arrow on the right to see the available applications in a list. Settings lets you change the theme, regional settings, and the date and time in your emulator.  It also has an applications settings pane, but this currently isn’t populated. The Time settings shows a unique Windows Phone UI. You can return to the home screen by pressing the Windows button.  Here’s the Internet Explorer app running, with the virtual keyboard open to enter an address.  Please note that this emulator can also accept input from your keyboard, so you can enter addresses without clicking on the virtual keyboard. And here’s Google running in Internet Explorer on Windows Phone 7. Windows Phone 7 supports accelerometers, and you can simulate this in the emulator.  Click one of the rotate buttons to rotate the screen in that direction. Here’s our favorite website in Internet Explorer on Windows Phone 7 in landscape mode. All this, running right inside your Windows 7 desktop… Developer tools for Windows Phone 7 Although it may be fun to play with the Windows Phone 7 emulator, developers will be more excited to actually be able to create new and exciting apps for it.  The Windows Phone Developer Tools download includes Visual Studio Express and XNA Game Studio 4.0 which lets you create enticing games and apps for Windows Phones.  All development for Windows Phones will be in C#, Silverlight, and the XNA game framework.  Visual Studio Express for Windows Phone includes templates for these, and additionally has code samples to help you get started with development. Conclusion Many features are still not functional in this preview version, such as the search button and most of the included applications.  However, this still gives you a great way to experience firsthand the future of the Windows Phone platform.  And, for developers, this is your chance to set your mark on the Windows Phone 7 Series even before it is released to the public.  Happy playing and developing!

  • SQLAuthority News – Memories at Anniversary of SQL Wait Stats Book

    - by pinaldave
    SQL Wait Stats About a year ago, I had very proud moment. I had published my second book SQL Server Wait Stats with me as a primary author. It has been a long journey since then. The book got great response and it was widely accepted in the community. It was first of its kind of book written specifically on Wait Stats and Performance. The book was based on my earlier month long series written on the same subject SQL Server Wait Stats. Today, on the anniversary of the book, lots of things come to my mind let me share a few here. Idea behind Blog Series A very common question I often receive is why I wrote a 30 day series on Wait Stats. There were two reasons for it. 1) I have been working with SQL Server for a long time and have troubleshoot more than hundreds of SQL Server which are related to performance tuning. It was a great experience and it taught me a lot of new things. I always documented my experience. After a while I found that I was able to completely rely on my own notes when I was troubleshooting any servers. It is right then I decided to document my experience for the community. 2) While working with wait stats there were a few things, which I thought I knew it well as they were working. However, there was always a fear in the back of mind that what happens if what I believed was incorrect and I was on the wrong path all the time. There was only one way to get it validated. Put it out in front community with my understanding and request further help to improve my understanding. It worked, it worked beautifully. I received plenty of conversations, emails and comments. I refined my content based on various conversations and make it more relevant and near accurate. I guess above two are the major reasons for beginning my journey on writing Wait Stats blog series. Idea behind Book After writing a blog series there was a good amount of request I keep on receiving that I should convert it to eBook or proper book as reading blog posts is great but it goes not give a comprehensive understanding of the subject. The very common feedback from users who were beginning the subject that they will prefer to read it in a structured method. After hearing the feedback for more than 4 months, I decided to write a book based on the blog posts. When I envisioned book, I wanted to make sure this book addresses the wait stats concepts from the fundamentals and fill the gaps of blogs I wrote earlier. Rick Morelan and Joes 2 Pros Team I must acknowledge my co-author Rick Morelan for his unconditional support in writing this book. I had already authored one book before I published this book. The experience to write the book was out of the world. Writing blog posts are much much easier than writing books. The efforts it takes to write a book is 100 times more even though the content is ready. I could have not done it myself if there was not tremendous support of my co-author and editor’s team. We spend days and days researching and discussing various concepts covered in the book. When we were in doubt we reached out to experts as well did a practical reproduction of the scenarios to validate the concepts and claims. After continuous 3 months of hard work we were able to get this book out in the community. September 1st – the lucky day Well, we had to select any day to publish the books. When book was completed in August last week we felt very glad. We all had worked hard and having a sample draft book in hand was feeling like having a newborn baby in our hand. Every time my books are published I feel the same joy which I had when my daughter was born. The feeling of holding a new book in hand is the (almost) same feeling as holding newborn baby. I am excited. For me September 1st has been the luckiest day in mind life. My daughter Shaivi was born on September 1st. Since then every September first has been excellent day and have taken me to the next step in life. I believe anything and everything I do on September 1st it is turning out to be successful and blessed. Rick and I had finished a book in the last week of August. We sent it to the publisher (printer) and asked him to take the book live as soon as possible. We did not decide on any date as we wanted the book to get out as fast as it can. Interesting enough, the publisher/printer selected September 1st for publishing the book. He published the book on 1st September and I knew it at the same time that this book will go next level. Book Model – The Most Beautiful Girl We were done with book. We had no budget left for marketing. Rick and I had a long conversation regarding how to spread the words for the book so it can reach to many people. While we were talking about marketing Rick come up with the idea that we should hire a most beautiful girl around who acknowledge our book and genuinely care for book. It was a difficult task and Rick asked me to find a more beautiful girl. I am a father and the most beautiful girl for me my daughter. This was not a difficult task for me. Rick had given me task to find the most beautiful girl and I just could not think of anyone else than my own daughter. I still do not know what Rick thought about this idea but I had already made up my mind. You can see the detailed blog post here. The Fun Experiments Book Signing Event We had lots of fun moments along this book. We have given away more books to people for free than we have sold them actually. We had done book signing events, contests, and just plain give away when we found people can be benefited from this book. There was never an intention to make money and get rich. We just wanted that more and more people know about this new concept and learn from it. Today when I look back to the earnings there is nothing much we have earned if you talk about dollars. However the best reward which we have received is the satisfaction and love of community. The amount of emails, conversations we have so far received for this book is over thousands. We had fun writing this book, it was indeed a very satisfying journey. I have earned lots of friends while learning and exploring. Availability The book is one year old but still very relevant when it is about performance tuning. It is available at various online book stores. If you have read the book, do let me know what you think of it.

  • SQL SERVER – Interview Questions and Answers – Frequently Asked Questions – Introduction – Day 1 of 31

    - by pinaldave
    List of all the Interview Questions and Answers Series blogs Posts covering interview questions and answers always make for interesting reading.  Some people like the subject for their helpful hints and thought provoking subject, and others dislike these posts because they feel it is nothing more than cheating.  I’d like to discuss the pros and cons of a Question and Answer format here. Interview Questions and Answers are Helpful Just like blog posts, books, and articles, interview Question and Answer discussions are learning material.  The popular Dummy’s books or Idiots Guides are not only for “dummies,” but can help everyone relearn the fundamentals.  Question and Answer discussions can serve the same purpose.  You could call this SQL Server Fundamentals or SQL Server 101. I have administrated hundreds of interviews during my career and I have noticed that sometimes an interviewee with several years of experience lacks an understanding of the fundamentals.  These individuals have been in the industry for so long, usually working on a very specific project, that the ABCs of the business have slipped their mind. Or, when a college graduate is looking to get into the industry, he is not expected to have experience since he is just graduated. However, the new grad is expected to have an understanding of fundamentals and theory.  Sometimes after the stress of final exams and graduation, it can be difficult to remember the correct answers to interview questions, though. An interview Question and Answer discussion can be very helpful to both these individuals.  It is simply a way to go back over the building blocks of a topic.  Many times a simple review like this will help “jog” your memory, and all those previously-memorized facts will come flooding back to you.  It is not a way to re-learn a topic, but a way to remind yourself of what you already know. A Question and Answer discussion can also be a way to go over old topics in a more interesting manner.  Especially if you have been working in the industry, or taking lots of classes on the topic, everything you read can sound like a repeat of what you already know.  Going over a topic in a new format can make the material seem fresh and interesting.  And an interested mind will be more engaged and remember more in the end. Interview Questions and Answers are Harmful A common argument against a Question and Answer discussion is that it will give someone a “cheat sheet.” A new guy with relatively little experience can read the interview questions and answers, and then memorize them. When an interviewer asks him the same questions, he will repeat the answers and get the job. Honestly, is he good hire because he memorized the interview questions? Wouldn’t it be better for the interviewer to hire someone with actual experience?  The answer is not as easy as it seems – there are many different factors to be considered. If the interviewer is asking fundamentals-related questions only, he gets the answers he wants to hear, and then hires this first candidate – there is a good chance that he is hiring based on personality rather than experience.  If the interviewer is smart he will ask deeper questions, have more than one person on the interview team, and interview a variety of candidates.  If one interviewee happens to memorize some answers, it usually doesn’t mean he will automatically get the job at the expense of more qualified candidates. Another argument against interview Question and Answers is that it will give candidates a false sense of confidence, and that they will appear more qualified than they are. Well, if that is true, it will not last after the first interview when the candidate is asked difficult questions and he cannot find the answers in the list of interview Questions and Answers.  Besides, confidence is one of the best things to walk into an interview with! In today’s competitive job market, there are often hundreds of candidates applying for the same position.  With so many applicants to choose from, interviewers must make decisions about who to call back and who to hire based on their gut feeling.  One drawback to reading an interview Question and Answer article is that you might sound very boring in your interview – saying the same thing as every single candidate, and parroting answers that sound like someone else wrote them for you – because they did.  However, it is definitely better to go to an interview prepared, just make sure that you give a lot of thought to your answers to make them sound like your own voice.  Remember that you will be hired based on your skills as well as your personality, so don’t think that having all the right answers will make get you hired.  A good interviewee will be prepared, confident, and know how to stand out. My Opinion A list of interview Questions and Answers is really helpful as a refresher or for beginners. To really ace an interview, one needs to have real-world, hands-on experience with SQL Server as well. Interview questions just serve as a starter or easy read for experienced professionals. When I have to learn new technology, I often search online for interview questions and get an idea about the breadth and depth of the technology. Next Action I am going to write about interview Questions and Answers for next 30 days. I have previously written a series of interview questions and answers; now I have re-written them keeping the latest version of SQL Server and current industry progress in mind. If you have faced interesting interview questions or situations, please write to me and I will publish them as a guest post. If you want me to add few more details, leave a comment and I will make sure that I do my best to accommodate. Tomorrow we will start the interview Questions and Answers series, with a few interesting stories, best practices and guest posts. We will have a prize give-away and other awards when the series ends.

  • Best Practices - which domain types should be used to run applications

    - by jsavit
    This post is one of a series of "best practices" notes for Oracle VM Server for SPARC (formerly named Logical Domains) One question that frequently comes up is "which types of domain should I use to run applications?" There used to be a simple answer in most cases: "only run applications in guest domains", but enhancements to T-series servers, Oracle VM Server for SPARC and the advent of SPARC SuperCluster have made this question more interesting and worth qualifying differently. This article reviews the relevant concepts and provides suggestions on where to deploy applications in a logical domains environment. Review: division of labor and types of domain Oracle VM Server for SPARC offloads many functions from the hypervisor to domains (also called virtual machines). This is a modern alternative to using a "thick" hypervisor that provides all virtualization functions, as in traditional VM designs, This permits a simpler hypervisor design, which enhances reliability, and security. It also reduces single points of failure by assigning responsibilities to multiple system components, which further improves reliability and security. In this architecture, management and I/O functionality are provided within domains. Oracle VM Server for SPARC does this by defining the following types of domain, each with their own roles: Control domain - management control point for the server, used to configure domains and manage resources. It is the first domain to boot on a power-up, is an I/O domain, and is usually a service domain as well. I/O domain - has been assigned physical I/O devices: a PCIe root complex, a PCI device, or a SR-IOV (single-root I/O Virtualization) function. It has native performance and functionality for the devices it owns, unmediated by any virtualization layer. Service domain - provides virtual network and disk devices to guest domains. Guest domain - a domain whose devices are all virtual rather than physical: virtual network and disk devices provided by one or more service domains. In common practice, this is where applications are run. Typical deployment A service domain is generally also an I/O domain: otherwise it wouldn't have access to physical device "backends" to offer to its clients. Similarly, an I/O domain is also typically a service domain in order to leverage the available PCI busses. Control domains must be I/O domains, because they boot up first on the server and require physical I/O. It's typical for the control domain to also be a service domain too so it doesn't "waste" the I/O resources it uses. A simple configuration consists of a control domain, which is also the one I/O and service domain, and some number of guest domains using virtual I/O. In production, customers typically use multiple domains with I/O and service roles to eliminate single points of failure: guest domains have virtual disk and virtual devices provisioned from more than one service domain, so failure of a service domain or I/O path or device doesn't result in an application outage. This is also used for "rolling upgrades" in which service domains are upgraded one at a time while their guests continue to operate without disruption. (It should be noted that resiliency to I/O device failures can also be provided by the single control domain, using multi-path I/O) In this type of deployment, control, I/O, and service domains are used for virtualization infrastructure, while applications run in guest domains. Changing application deployment patterns The above model has been widely and successfully used, but more configuration options are available now. Servers got bigger than the original T2000 class machines with 2 I/O busses, so there is more I/O capacity that can be used for applications. Increased T-series server capacity made it attractive to run more vertical applications, such as databases, with higher resource requirements than the "light" applications originally seen. This made it attractive to run applications in I/O domains so they could get bare-metal native I/O performance. This is leveraged by the SPARC SuperCluster engineered system, announced a year ago at Oracle OpenWorld. In SPARC SuperCluster, I/O domains are used for high performance applications, with native I/O performance for disk and network and optimized access to the Infiniband fabric. Another technical enhancement is the introduction of Direct I/O (DIO) and Single Root I/O Virtualization (SR-IOV), which make it possible to give domains direct connections and native I/O performance for selected I/O devices. A domain with either a DIO or SR-IOV device is an I/O domain. In summary: not all I/O domains own PCI complexes, and there are increasingly more I/O domains that are not service domains. They use their I/O connectivity for performance for their own applications. However, there are some limitations and considerations: at this time, a domain using physical I/O cannot be live-migrated to another server. There is also a need to plan for security and introducing unneeded dependencies: if an I/O domain is also a service domain providing virtual I/O go guests, it has the ability to affect the correct operation of its client guest domains. This is even more relevant for the control domain. where the ldm has to be protected from unauthorized (or even mistaken) use that would affect other domains. As a general rule, running applications in the service domain or the control domain should be avoided. To recap: Guest domains with virtual I/O still provide the greatest operational flexibility, including features like live migration. I/O domains can be used for applications with high performance requirements. This is used to great effect in SPARC SuperCluster and in general T4 deployments. Direct I/O (DIO) and Single Root I/O Virtualization (SR-IOV) make this more attractive by giving direct I/O access to more domains. Service domains should in general not be used for applications, because compromised security in the domain, or an outage, can affect other domains that depend on it. This concern can be mitigated by providing guests' their virtual I/O from more than one service domain, so an interruption of service in the service domain does not cause an application outage. The control domain should in general not be used to run applications, for the same reason. SPARC SuperCluster use the control domain for applications, but it is an exception: it's not a general purpose environment; it's an engineered system with specifically configured applications and optimization for optimal performance. These are recommended "best practices" based on conversations with a number of Oracle architects. Keep in mind that "one size does not fit all", so you should evaluate these practices in the context of your own requirements. Summary Higher capacity T-series servers have made it more attractive to use them for applications with high resource requirements. New deployment models permit native I/O performance for demanding applications by running them in I/O domains with direct access to their devices. This is leveraged in SPARC SuperCluster, and can be leveraged in T-series servers to provision high-performance applications running in domains. Carefully planned, this can be used to provide higher performance for critical applications.

    After doing the Twitter example, it seemed reasonable to try graphing the result with JavaFX.  At this time the Nashorn project doesn't have an JavaFX shell, so we have to go through some hoops to create an JavaFX application.  I thought showing you some of those hoops might give you some idea about what you can do mixing Nashorn and Java (we'll add a JavaFX shell to the todo list.) First, let's look at the meat of the application.  Here is the repackaged version of the original twitter example. var twitter4j      = Packages.twitter4j; var TwitterFactory = twitter4j.TwitterFactory; var Query          = twitter4j.Query; function getTrendingData() {     var twitter = new TwitterFactory().instance;     var query   = new Query("nashorn OR nashornjs");     query.since("2012-11-21");     query.count = 100;     var data = {};     do {         var result = twitter.search(query);         var tweets = result.tweets;         for each (tweet in tweets) {             var date = tweet.createdAt;             var key = (1900 + date.year) + "/" +                       (1 + date.month) + "/" +                       date.date;             data[key] = (data[key] || 0) + 1;         }     } while (query = result.nextQuery());     return data; } Instead of just printing out tweets, getTrendingData tallies "tweets per date" during the sample period (since "2012-11-21", the date "New Project: Nashorn" was posted.)   getTrendingData then returns the resulting tally object. Next, use JavaFX BarChart to display that data. var javafx         = Packages.javafx; var Stage          = javafx.stage.Stage var Scene          = javafx.scene.Scene; var Group          = javafx.scene.Group; var Chart          = javafx.scene.chart.Chart; var FXCollections  = javafx.collections.FXCollections; var ObservableList = javafx.collections.ObservableList; var CategoryAxis   = javafx.scene.chart.CategoryAxis; var NumberAxis     = javafx.scene.chart.NumberAxis; var BarChart       = javafx.scene.chart.BarChart; var XYChart        = javafx.scene.chart.XYChart; var Series         = XYChart.Series; var Data           = XYChart.Data; function graph(stage, data) {     var root = new Group();     stage.scene = new Scene(root);     var dates = Object.keys(data);     var xAxis = new CategoryAxis();     xAxis.categories = FXCollections.observableArrayList(dates);     var yAxis = new NumberAxis("Tweets", 0.0, 200.0, 50.0);     var series = FXCollections.observableArrayList();     for (var date in data) {         series.add(new Data(date, data[date]));     }     var tweets = new Series("Tweets", series);     var barChartData = FXCollections.observableArrayList(tweets);     var chart = new BarChart(xAxis, yAxis, barChartData, 25.0);     root.children.add(chart); } I should point out that there is a lot of subtlety going on in the background.  For example; stage.scene = new Scene(root) is equivalent to stage.setScene(new Scene(root)). If Nashorn can't find a property (scene), then it searches (via Dynalink) for the Java Beans equivalent (setScene.)  Also note, that Nashorn is magically handling the generic class FXCollections.  Finally,  with the call to observableArrayList(dates), Nashorn is automatically converting the JavaScript array dates to a Java collection.  It really is hard to identify which objects are JavaScript and which are Java.  Does it really matter? Okay, with the meat out of the way, let's talk about the hoops. When working with JavaFX, you start with a main subclass of javafx.application.Application.  This class handles the initialization of the JavaFX libraries and the event processing.  This is what I used for this example; import java.io.IOException; import java.io.InputStream; import java.io.InputStreamReader; import javafx.application.Application; import javafx.stage.Stage; import javax.script.ScriptEngine; import javax.script.ScriptEngineManager; import javax.script.ScriptException; public class TrendingMain extends Application { private static final ScriptEngineManager MANAGER = new ScriptEngineManager(); private final ScriptEngine engine = MANAGER.getEngineByName("nashorn"); private Trending trending; public static void main(String[] args) { launch(args); } @Override public void start(Stage stage) throws Exception { trending = (Trending) load("Trending.js"); trending.start(stage); } @Override public void stop() throws Exception { trending.stop(); } private Object load(String script) throws IOException, ScriptException { try (final InputStream is = TrendingMain.class.getResourceAsStream(script)) { return engine.eval(new InputStreamReader(is, "utf-8")); } } } To initialize Nashorn, we use JSR-223's javax.script.  private static final ScriptEngineManager MANAGER = new ScriptEngineManager(); private final ScriptEngine engine = MANAGER.getEngineByName("nashorn"); This code sets up an instance of the Nashorn engine for evaluating scripts. The  load method reads a script into memory and then gets engine to eval that script.  Note, that load also returns the result of the eval. Now for the fun part.  There are several different approaches we could use to communicate between the Java main and the script.  In this example we'll use a Java interface.  The JavaFX main needs to do at least start and stop, so the following will suffice as an interface; public interface Trending {     public void start(Stage stage) throws Exception;     public void stop() throws Exception; } At the end of the example's script we add; (function newTrending() {     return new Packages.Trending() {         start: function(stage) {             var data = getTrendingData();             graph(stage, data);             stage.show();         },         stop: function() {         }     } })(); which instantiates a new subclass instance of Trending and overrides the start and stop methods.  The result of this function call is what is returned to main via the eval. trending = (Trending) load("Trending.js"); To recap, the script Trending.js contains functions getTrendingData, graph and newTrending, plus the call at the end to newTrending.  Back in the Java code, we cast the result of the eval (call to newTrending) to Trending, thus, we end up with an object that we can then use to call back into the script.  trending.start(stage); Voila. ?

  • cisco 2911 router vs 2811 router

    - by NickToyota
    Just wondering if anyone has experience with the cisco 2911 or 2900 series routers. I understand it is newer and similar to the 2811 but more robust. The price difference is not that much more. I am trying to determine if I should go with the 29xx or 28xx series for a small-medium sized company. ISP bandwidth load balancing and fail over is required. T1 and ADSL lines already in place.

  • Radeon 68xx, 69xx cards and support for 10-bit color over displayport [closed]

    - by aCuria
    10-bit color, aka "Deep Color" is a scheme where 10 bits are used for each color channel. This makes for a 30 bit RGB implementation. IE: red: 10 bits green: 10 bits blue: 10 bits total: 30 bits For more information, please consult this link http://en.wikipedia.org/wiki/RGB_color_model#Beyond_truecolor:_deep_color Radeon 6000 series cards DO support deep color over HDMI, but HDMI also limits the output resolution to 1920x1200, which is not optimal. I want to know if Deep color is possible over display port with the HD6xxx series graphics cards.

  • T60 Screen/LCD gets black after some minutes with a highpitched sound rising and fading

    Just now my T60 screen got "black" (so no display). On my second monitor: no problems so the vga output works. symptom: Screen blanks / no display but works on second monitor steps to reproduce: - boot - wait (it does not matter what you do you do not have to login or anything) - (now the monitor of the laptop slowly begins to make a ssssssssHHHHHHHHHHHHHHHHHWOEOEssssssss noice of about 10 seconds) - right after the sounds ends the monitor gets black times seem to be the same each time. software: installed no new software before/after, running zone alarm and antivirus. other: it does not feel hot in any place, there dont seem to be running processes with strange behaviour. warranty: out of warranty what was i doing: typing text on a website and doing some php coding in a text editor. Anyone any idea what I can do here other than buy a new laptop? / does it sound familiar to known cases? update: * exactly the same problem: http://forums.lenovo.com/t5/T61-and-prior-T-series-ThinkPad/T60-Screen-Blackout/m-p/288772 and the second poster (garyj) here: http://forums.lenovo.com/t5/T61-and-prior-T-series-ThinkPad/Black-Screen-on-T60/m-p/235053#M48627 and here: "i have that same problem. i replaced the CCRL on mine and it works fine when the screen is not screwed in. once the frame of the LCD screen (metal portion) touches the metal on the laptop which holds the screen the screen goes black. If the metal is touching the screen when you boot up it boots up with it being very dimmly lit. " from http://forums.lenovo.com/t5/T61-and-prior-T-series-ThinkPad/T60-screen-problems/m-p/205047#M44995 (it seems replacing the lcd is no use, he tried it 3 times). same problem: http://forums.lenovo.com/t5/T61-and-prior-T-series-ThinkPad/T60-black-screen/m-p/80604#M25914 Hmmm... not handy 3 or 4 months ago I ordered and installed a new fan. Now the LCD. Which does not seem the core isse but some electric issue so it seems replacing the LCD is not the thing todo here. I have the following question: If it is not the LCD that needs to be replaced (see other threads) which parts can I order to fix this? Has anyone got any information which could lead me to identify the issue? I have read replacing the "inverter" AND the "backlightning" would that make sense?

As a consequence of production capacity in between 600~800t/h of mining stone crusher, stone is mine Mobile Cone Crushing Plant Price 25~40 times, effectively solved the initially mining stone crusher operation because of low yield prices, no upkeep problems. Full chunk of mining stone crusher. Maximum particle size for crushing 1000x1200mm, an effective answer for the original side is mine stone provide, storing significant chunks of stone can not use complications in mines. Completed goods granularity is modest, only 2~15mm, an effective option for the original mine stone size, generally blocking chute production was an issue even the grinding machine. Two types of material mixed great uniformity, desulfurization of mining stone by adding weight considerably. Present quantity added is often reached 60%, effectively minimizing the cost of raw supplies. Electrical energy consumption has fallen. Dropped 1~2KWh/t tons of mining stone electrical energy consumption, annual electricity savings of one hundred,000 yuan. Efficient labor intensity of workers and also the atmosphere.

  • ASA and cisco vs NSA sonic firewall

    - by Lbaker101
    Currently I’m trying to structure our network to fully support and be redundant with BGP/Multi homing. Our current company size is 40 employees but the major part of that is our Development department. We are a software company and continued connection to the internet is a requirement as 90% of work stops when the net goes down. The only thing hosted on site (that needs to remain up) is our exchange server. Right now i'm faced with 2 different directions and was wondering if I could get your opinions on this. We will have 2 ISPs that are both 20meg up/down and dedicated fiber (so 40megs combined). This is handed off as an Ethernet cable into our server room. ISP#1 first digital ISP#2 CenturyLink we currently have 2x ASA5505s but the 2nd one is not in use. It was there to be a failover and it just needs the security+ license to be matched with the primary device. But this depends on the network structure. I have been looking into the hardware that would be required to be fully redundant and I found that we will either of the following. 2x Cisco 2921+ series routers with failover licenses. They will go in front of the ASAs and either connects in a failover state or 1 ISP into each of the 2921 series routers and then 1 line into each of the ASAs (thus all 4 hardware components will be used actively). So 2x Cisco 2921+ series routers 2x Cisco ASA5505 firewalls The other route 2x SonicWalls NSA2400MX series. 1 primary and the secondary will be in a failover state. This will remove the ASAs from the network and be about 2k cheaper than the cisco route. This also brings down the points of failure because it’s just the 2x sonicwalls It will also allow us to scale all the way up to 200-400 users (depending on their configuration). This also makes so the Sonic walls. So the real question is with the added functionality ect of the sonicwall is there a point in paying so much more to stay the cisco route? Thanks!

  • Professional graphics cards a "must" for rendering static environments?

    - by Imhotep
    I'm not sure if the title is clear but with more words what I want to say is: I'm building a PC for a decorator who's main work is to render photorealistic images of house interiors. For that she uses 3dsMax and AutoCAD with Accurender and Photoshop. Is there a need for professional graphics card like Quadro series or FireGL series? Do these cards offer any improvements on rendering time or are they only used for real time rendering?

  • How do I plot the warping of DTW result using gnuplot?

    - by Ekkmanz
    Hello, Right now I have implemented Dynamic Time Warping algorithm for warping two 3D trajectories. Currently, gnuplot is my plotting tool of choice and it works fine when I plot multiple trajectories at a time. However, when I implement DTW one of the real use for plotting tool is to visualize the point warping, like this picture. Currently, the output of my DTW program is two time series in CSV files and another CSV file which indicate the warp (X in series 1 - Y in series 2). Is there any possible way to do that in gnuplot?
