  • Tic Tac Toe Winner in Javascript and html [closed]

    - by Yehuda G
    I am writing a tic tac toe game using html, css, and JavaScript. I have my JavaScript in an external .js file being referenced into the .html file. Within the .js file, I have a function called playerMove, which allows the player to make his/her move and switches between player 'x' and 'o'. What I am trying to do is determine the winner. Here is what I have: each square, when onclick(this), references playerMove(piece). After each move is made, I want to run an if statement to check for the winner, but am unsure if the parameters would include a reference to 'piece' or a,b, and c. Any suggestions would be greatly appreciated. Javascript: var turn = 0; a = document.getElementById("topLeftSquare").innerHTML; b = document.getElementById("topMiddleSquare").innerHTML; c = document.getElementById("topRightSquare").innerHTML; function playerMove(piece) { var win; if(piece.innerHTML != 'X' && piece.innerHTML != 'O'){ if(turn % 2 == 0){ document.getElementById('playerDisplay').innerHTML= "X Plays " + printEquation(1); piece.innerHTML = 'X'; window.setInterval("X", 10000) piece.style.color = "red"; if(piece.innerHTML == 'X') window.alert("X WINS!"); } else { document.getElementById('playerDisplay').innerHTML= "O Plays " + printEquation(1); piece.innerHTML = 'O'; piece.style.color = "brown"; } turn+=1; } html: <div id="board"> <div class="topLeftSquare" onclick="playerMove(this)"> </div> <div class="topMiddleSquare" onclick="playerMove(this)"> </div> <div class="topRightSquare" onclick="playerMove(this)"> </div> <div class="middleLeftSquare" onclick="playerMove(this)"> </div> <div class="middleSquare" onclick="playerMove(this)"> </div> <div class="middleRightSquare" onclick="playerMove(this)"> </div> <div class="bottomLeftSquare" onclick="playerMove(this)"> </div> <div class="bottomMiddleSquare" onclick="playerMove(this)"> </div> <div class="bottomRightSquare" onclick="playerMove(this)"> </div> </div>

  • Extensible Metadata in Oracle IRM 11g

    - by martin.abrahams
    Another significant change in Oracle IRM 11g is that we now use XML to create the tamperproof header for each sealed document. This article explains what this means, and what benefit it offers. So, every sealed file has a metadata header that contains information about the document - its classification, its format, the user who sealed it, the name and URL of the IRM Server, and much more. The IRM Desktop and other IRM applications use this information to formulate the request for rights, as well as to enhance the user experience by exposing some of the metadata in the user interface. For example, in Windows explorer you can see some metadata exposed as properties of a sealed file and in the mouse-over tooltip. The following image shows 10g and 11g metadata side by side. As you can see, the 11g metadata is written as XML as opposed to the simple delimited text format used in 10g. So why does this matter? The key benefit of using XML is that it creates the opportunity for sealing applications to use custom metadata. This in turn creates the opportunity for custom classification models to be defined and enforced. Out of the box, the solution uses the context classification model, in which two particular pieces of metadata form the basis of rights evaluation - the context name and the document's item code. But a custom sealing application could use some other model entirely, enabling rights decisions to be evaluated on some other basis. The integration with Oracle Beehive is a great example of this. When a user adds a document to a Beehive workspace, that document can be automatically sealed with metadata that represents the Beehive security model rather than the context model. As a consequence, IRM can enforce the Beehive security model precisely and all rights configuration can actually be managed through the Beehive UI rather than the IRM UI. In this scenario, IRM simply supports the Beehive application, seamlessly extending Beehive security to all copies of workspace documents without any additional administration. Finally, I mentioned that the metadata header is tamperproof. This is obviously to stop a rogue user modifying the metadata with a view to gaining unauthorised access - reclassifying a board document to a less sensitive classifcation, for example. To prevent this, the header is digitally signed and can only be manipulated by a suitably authorised sealing application.

  • How should I pitch moving to an agile/iterative development cycle with mandated 3-week deployments?

    - by Wayne M
    I'm part of a small team of four, and I'm the unofficial team lead (I'm lead in all but title, basically). We've largely been a "cowboy" environment, with no architecture or structure and everyone doing their own thing. Previously, our production deployments would be every few months without being on a set schedule, as things were added/removed to the task list of each developer. Recently, our CIO (semi-technical but not really a programmer) decided we will do deployments every three weeks; because of this I instantly thought that adopting an iterative development process (not necessarily full-blown Agile/XP, which would be a huge thing to convince everyone else to do) would go a long way towards helping manage expectations properly so there isn't this far-fetched idea that any new feature will be done in three weeks. IMO the biggest hurdle is that we don't have ANY kind of development approach in place right now (among other things like no CI or automated tests whatsoever). We don't even use Waterfall, we use "Tell Developer X to do a task, expect him to do everything and get it done". Are there any pointers that would help me start to ease us towards an iterative approach and A) Get the other developers on board with it and B) Get management to understand how iterative works? So far my idea involves trying to set up a CI server and get our build process automated (it takes about 10-20 minutes right now to simply build the application to put it on our development server), since pushing tests and/or TDD will be met with a LOT of resistance at this point, and constantly force us to break larger projects into smaller chunks that could be done iteratively in a three-week cycle; my only concern is that, unless I'm misunderstanding, an agile/iterative process may or may not release the software (depending on the project scope you might have "working" software after three weeks, but there isn't enough of it that works to let users make use of it), while I think the expectation here from management is that there will always be something "ready to go" in three weeks, and that disconnect could cause problems. On that note, is there any literature or references that explains the agile/iterative approach from a business standpoint? Everything I've seen only focuses on the developers, how to do it, but nothing seems to describe it from the perspective of actually getting the buy-in from the businesspeople.

  • Oracle BPM: Adding an attachment during the Human Task Initialization

    - by kyap
    Recently I had the requirement from a customer to instantiate a Human Task, which can accept a payload containing a binary attribute (base64) representing an actual document. According to the same requirement, this attribute should be shown as a hyperlink in the Worklist UI to the assignee(s), from which the assignees can download the document on the local machine for review. Multiple options have been leverage, but most required heavy customization.  In order to leverage as much as possible Oracle BPM out-of-the box functionalities, I decided to add this document as a readonly attachment. We can easily achieve this operation within Worklist Application, but it is a bit more challenging when we want to attach the document during the Human Task initialization.  After some investigations (on BPM 11g PS4FP and PS5), here's the way to go: 1. Create an asynchronous BPM process, and use this xsd to create 2 Business Objects FullPayload and PartialPayload : 2. Create 2 process variables 'vFullPayload' and 'vPartialPayload' using this Business Objects created above 3. Implement the Start Event with the initial Data Association, with an input argument using 'FullPayload' Business Object type 4. Drag in an User Task into the process. Implement the User Task as usual by using 'vPartialPayload' type as the input type and assign the task to your favorite tester (mine is jcooper) 5. Here's the main course - Start the Data Association and map the payload into 'execData' as follow: FROM TO  vFullPayload.attachment.mimetype  execData.attachment[1].mimeType  vFullPayload.attachment.filename  execData.attachment[1].name  bpmn:getDataObject('vFullPayload')/ns:attachment/ns:content  execData.attachment[1].content  'BPM'  execData.attachment[1].attachmentScope false()  execData.attachment[1].doesBelongToParent 'weblogic'  execData.attachment[1].updateBy  xp20:current-dateTime()  execData.attachment[1].updateDate (Note: Check the <Humantask>WorkflowTask.xsd file in your project xsd folder to discover the different options for attachmentScope & storageType) 6. Your process is completed. Just build a standard ADF UI and deploy the process/UI onto your BPM Server for the testing. Here's an example, with a base64 encoded pdf file: application-pdf.txt 7. Finally, go to the BPM Worklist application to check the result ! Please note that Oracle BPM, by default, limits the attachment document size to 2Mb. If you are planning to have bigger attachments in your process, it is recommended to store your documents in a Content Management server (such as Oracle UCM) and pass the reference instead. It is possible to configure Oracle BPM to store attachment directly into Oracle UCM too, and I believe we can use the storageType, ucmMetadataItem attributes for this purpose.... I will confirm once I have access onto an Oracle UCM for the testing :)

  • Hello From South Florida

    - by Sam Abraham
    Fellow Blog Readers: I figured I use my first blog post on GeeksWithBlogs to introduce myself.   I recently relocated from Long Island, NY to South Florida where I joined a local company as Software Engineer specializing in technologies such as C#, ASP.Net 3.5, WCF, Silverlight, SQL Server 2008 and LINQ, to name a few. I am an MCP and MCTS ASP.Net 3.5, looking to get my .Net 4.0 certification soon.   Having been in industry for a few years so far, I figured I would share with you my take on the importance of being involved(at least attending) in local user groups.   I am a firm believer that besides using a certain technology, the best way to expand one’s knowledge is by sharing it with others and being equally open to learn from others just as much as you are willing to share what you know.   In my opinion, an important factor that makes a good developer stand-out is his/her ability to keep abreast with the latest and greatest even in areas outside his/her direct expertise.   Additionally, having spoken to various recruiters, technical user group attendees are always favorably looked upon as genuinely interested in their field and willing to take the initiative to expand their knowledge which offers job candidates good leverage when competing for jobs.   I believe I am very blessed to be in an area with a very strong and vibrant developer community. I found in the local .Net community leadership a genuine interest in constantly extending the opportunity to all developers to get more involved and encouraging those who are willing to take that initiative achieve their goal: Speak in meetings, volunteer at events or write and publish articles/blogs about latest and greatest technologies.   With Vishal Shukla (Site director for the West Palm Beach .Net User Group) traveling overseas, I have been extended the opportunity to come on board as site coordinator for FladotNet's WPB .Net User Group along with Venkata Subramanian, an opportunity which I gratefully accepted.   Being involved in running a .Net User Group will surely help me personally and professionally, but my real hope is to use this opportunity to assist in delivering the ultimate common-goal: spread the word about new .Net Technologies, help everybody get more involved and simply have fun learning new things.   With my introduction out of the way, in the next few days I will be posting some notes on an upcoming talk I will be giving about MVC2 and VS2010 in mid-April.   Environment.Exit(0); --Sam

  • Create Shortcuts for Your Favorite or Most Used Folders in Ubuntu

    - by Asian Angel
    Do you have certain folders that you access often each day but are only available through the Places Menu or Nautilus? See how easy it is to create shortcuts for your desktop and taskbar with our quick tutorial. To get started open Nautilus and locate the folders that you want to make new shortcuts for. For our example we chose Ubuntu One. Right click on the chosen folder and select Make Link. Your new shortcut will appear with the text Link to “Folder Name” and an Arrow Shortcut Marker attached. If you are happy with your new shortcut as is, then drag it to your desktop or taskbar as desired. We created the shortcut twice in our example…once for the desktop and once for the taskbar. For our example we decided to customize the taskbar shortcut a bit. To customize your shortcut right click on the shortcut and select Properties. Note: The desktop shortcut is limited on the amount you can customize it (name change and addition of up to four emblems to the folder). From here you can rename the shortcut and change the icon as desired. A quick name change and new icon made a huge improvement in how our taskbar shortcut looked. Note: The link for the icon we used is shown below. A little touch-up to our desktop shortcut and both are looking good.

  • Windows Desktop Virtualization Gets Easier

    - by andrewbrust
    This past Thursday, Microsoft announced that Windows (7) Virtual PC (WVPC) and its XP Mode feature would no longer require hardware assisted virtualization (HAV).  That means any PC running Windows 7 Pro, or higher, can now run this software.  And that’s a great thing because, as I noted in a post almost five month ago, determining whether a given PC you might be planning to buy actually offers HAV can be extremely difficult.  That meant even dedicated, sophisticated PC users, with a budget for new hardware, might be blocked from using this technology.  And that was just plain silly. One of the features offered by WVPC, and utilized heavily by XP Mode, is the concept of virtual applications: apps within a guest VM that can actually run within the host’s desktop environment.  I find this feature so powerful that my February Redmond Review column entertained the notion of a future version of Windows that runs all applications in this manner. The elimination of the HAV requirement for XP Mode and WVPC was just one of many virtualization-related announcements Microsoft made on Thursday.  And, interestingly, most of the others were also desktop-related, rather than server-related.  This is a welcome change from the multi-year period in which Microsoft enhanced its server virtualization lineup (in Hyper-V) and let the desktop platform fester.  Microsoft now seems to understand desktop virtualization is in high-demand and strengthens the Windows franchise.  As I explained in the column, even cloud computing can have a desktop spin if desktop virtualization is part of the equation. One company that knows this well is Citrix, and a closer alliance between Microsoft and Citrix was one of the many announcements from Thursday.  In fact, there’s a whole Web site dedicated to the alliance at http://www.citrixandmicrosoft.com/. I’d love to see virtual applications and entire virtual desktops offered as Azure-branded services.  This could allow me to run, for example, the full Office client on a variety of desktops I might use, and for large organizations it could easily reduce the expense, burden and duration of the deployment cycle for new versions of Office.  Business Intelligence providers, including my own firm, twentysix New York, would find great relief in enabling their customers to run the newest version of Excel, with the latest BI capabilities, instead of having to wait the requisite two to three years it takes for many Fortune 500 customers to upgrade. Microsoft should do more, and faster.  WVPC still does not support 64-bit guest images, even on 64-bit hosts.  That needs to be fixed.  File access from the guest to the host needs to be improved (right now, it’s done through Terminal Services/Remote Desktop file sharing, and it’s slow) and VM load times need to be significantly reduced before virtualized apps can become the norm.  (I suppose the advance of solid state drive technology will help there.) I do think these improvements will come, because Microsoft is focused on the virtual desktop now.  And that’s a smart focus to have.

  • Stop YouTube Videos from Automatically Playing in Chrome

    - by The Geek
    If you’ve actually used the internet before, you’ve probably come across a page with an auto-playing YouTube clip, and chances are good it was a rather annoying one. Here’s how to stop them from starting automatically in Chrome. We’ve already told you how to stop them from automatically playing if you’re a Firefox user (best answer: use Flashblock!), but now it’s time for Chrome users to get their turn. Use the Stop Autoplay for YouTube Extension The great thing about this extension is that it stops the video from playing, but it allows it to continue buffering, so when you do feel like playing the video, it’ll already be downloaded—really useful for people with slower internet connections. There’s no UI or anything fancy, just head to the extension page and click the Install button. If you want to get rid of it later, use the Tools –> Extensions menu (or you can type chrome://extensions/ into your address bar), and then click the Uninstall link for that add-on.   Download Stop Autoplay for YouTube [Google Chrome Extensions] Using FlashBlock for Chrome If you really wanted to, you could just disable Flash across the board using FlashBlock for Chrome. Once you’ve installed the extension, you won’t see any Flash elements anywhere, and you’ll have to move your mouse over them and click to enable them each time. When I installed the extension the first time, I noticed that YouTube was already in the allow list. I’m not sure if that’s the default setting or not, but you can use the icon in the address bar, or the Options from the Extensions panel to get to the settings page, and from there you can remove anything from the White List that you wouldn’t want. Another nice feature about Flash Block is that it can also block Silverlight, or you could simply uninstall or remove unnecessary Chrome plug-ins.

  • Javascript Implementation Patterns for Server-side MVC Websites

    - by tmo256
    I'm looking for information on common patterns for initializing and executing Javascript page by page in a "traditional" server-side MVC website architecture. A few months ago, my development team began, but abandoned, a major re-architecture of our company's primary web app, including a full front-end redesign. In the process, there was some debate about the architecture of the Javascript in the current version of the site, and whether it fit into a clear, modern design pattern. Now I've returned to the process of overhauling the front end of this and several other MVC websites (Ruby on Rails and MVC.net) to implement a responsive framework (Bootstrap), and in the process will again need to review then revamp and update a lot of Javascript. These web applications are NOT single-page Javascript applications (in fact, we are ripping out a lot of Ajax) or designed to require a Javascript MVC pattern; these apps are basically brochure, catalog and administrative sites that follow a server-side MVC pattern. The vast majority of the Javascript required is behavioral, pre-built plugins (JQuery and Bootstrap, et al) that execute on specific DOM nodes. I'm going to give a very brief (as brief as I can be) run-down of the current architecture only in order to illustrate the scope and type of paradigm I'm talking about. Hopefully, it will help you understand the nature of the patterns I'm looking for, but I'm not looking for commentary on the specifics of this code. What I've done in the past is relatively straight-forward and easy to maintain, but, as mentioned above, some of the other developers don't like the current architecture. Currently, on document ready, I execute whatever global Javascript needs to occur on every page, and then call a page-specific init function to initialize node-specific functionality, retrieving the init method from a JS object. On each page load, something like this will happen: $(document).ready(function(){ $('header').menuAction(); App.pages.executePage('home','show'); //dynamic from framework request object }); And the main App javascript is like App = { usefulGlobalVar: 0, pages: { executePage: function(action, controller) { // if exists, App.pages[action][controller].init() }, home: { show: { init: function() { $('#tabs').tabs(); //et. al }, normalizeName: function() { // dom-specific utility function that // doesn't require a full-blown component/class/module } }, edit: ... }, user_profile: ... } } Any common features and functionality requiring modularization or compotentizing is done as needed with prototyping. For common implementation of plugins, I often extend JQuery, so I can easily initialize a plugin with the same options throughout the site. For example, $('[data-tabs]').myTabs() with this code in a utility javascript file: (function($) { $.fn.myTabs = function() { this.tabs( { //...common options }); }; }) Pointers to articles, books or other discussions would be most welcome. Again, I am looking for a site-wide implementation pattern, NOT a JS MVC framework or general how-tos on creating JS classes or components. Thanks for your help!

  • Slow Start For Passbook

    - by David Dorf
    Like many others, I pre-ordered my iPhone 5 then downloaded iOS 6 to my antiquated iPhone 4.  I decided the downgrade in mapping capabilities was worth access to Passbook, Apple's wallet of sorts that holds loyalty cards, tickets, and coupons.  To my disappointment, Passbook didn't work.  When it goes to the iTunes Store, it can't connect.  After a little research, I read that you can change the date on the iPhone to the future (I did March 2013), and then it will connect.  A list of apps that support Passbook are shown, some of which were already on my iPhone and others that required downloading.  Even when I put the date back on "automatic," things continued to work.  Not sure why. Anyway, even once I got into iTunes and made sure I had some of the apps downloaded, it wasn't clear what the next step was (gimme a break, its Friday afternoon).  Every time I opened Passbook, it sent me to the "Apps for Passbook" page on iTunes.  I tried downloading one of the suggested apps that I didn't already have (Walgreens).  The app's icon has a "new" stripe across the icon.  I launched it and it said it had Passbook integration. So I needed to login or signup with the loyalty program.  After figuring out what my username and password already was, it then offered to add the loyalty card to Passbook, which I accepted.  Now when I flip over to Passbook, I can see the loyalty card there.  I guess I need to go into each app to "push" cards into Passbook. People seem to be using it.  Twenty-four hours after iOS 6 was released, Sephora had 20,000 users of Passbook. Starbucks says they'll be integrated to Passbook by the end of the month, and Target is already offering coupons via Passbook.  After a few more retailers get on board, Apple may not need to consider NFC.

  • Basic web architecture : Perl -> PHP

    - by Sunny Jim
    This is an architecture question. If there is a better forum, please redirect me. Apologies in advance. Essentially every website is built around a relational database, right? When a user uploads form data, that data is stored in a table. The problem is that the table structure(s) need to be modified whenever the website form is modified. Although I understand that modern web frameworks work around this problem by automatically building forms based on the table structure. For the last 20 years, I have been building websites using Perl. When I first encountered this problem, the easiest solution was to save serialized Perl objects as data BLOBS. After XML's introduction, this solution worked even better because XML is so effective for representing arbitrary data. This approach is consistent with the original Perl principles of Hubris, Laziness, and Impatience and I'm pretty committed to it. Obviously, the biggest drawback is that this solution locks me into the Perl interpreter. So instead, I've just completed a prototype of a universal RDB table. The prototype is written in Perl but porting it to PHP will be a good chance to develop those skills. The principal is based on the XML::Dumper module, which converts arbitrary Perl data structures into uniform XML. With my approach, each XML node is stored as a table record. I underestimated this undertaking and rolled something up myself. But the effort allows me to discuss the basic design instead of implementation details. As mentioned, I'm pretty committed to this approach of using flexible data structures. It's been successfully deployed on many websites, large, and complex. But are there any drawbacks I've overlooked? I rolled my own. Are other people taking a similar approach to their data? What kinds of solutions are available? I have not abandoned my dream of eventually contributing something useful to the worldwide community. In order to proceed, the next step would be peer review. How does one pursue that effort? Thanks! -Jim

  • 302: this blog will be closed

    - by preishuber
    After nearly 7 years I will discontinue blogging on this site. My resources are limited. You can reach my German blog which is used to support my customers. Looking back to a long an interesting journey ASP.NET by ScottGu That was the reason to attend this site and support Microsoft as much as I can. For that I was honored as ASP.NET MVP- thanks again. Meet Scoot several times. Great guy! Forums I have left NNTP forums a few years ago and now Microsoft closed it- It was my idea ;-) AJAX Was the wrong way- JQuery won the game IIS7 That is really a great plattform and the IIS team rules. I am sad that is so silent around that topic. ASP.NET after 2.0 Is no longer my world. I love ASP.NET and ASP.NET Server controls. I hate the discussion about how to follow the holy rules of MVC. Microsoft have dropped the goal to bring ASP.NET to #1 and accepted PHP is it. Facebook & Twittering Microblogging takes over a part of the blogging business. Shorter faster cheaper- or as SteveB mentioned - do more with less. Google Google is taking over the web. I am using Bing every time as I can but Google have more options. Sorry Microsoft you will loose that game. Apple That is not the biggest problem of Microsoft. the Ixxx takes over a small part but big money of the market, but the customers are not strongly linked. New wave new hype- Game over Apple. Silverlight My new home. I can reuse a lot of my skills and love the possibilitys. Silverligth will passing WPF-and strike Flash Windows phone 7 Also my skills fit. I just will use it for fun. I am not really satisfied about what I have heard from MIX. Guys from Redmond, I am sad to say you have been the best Smartphone OS and lost everything. The ADO vNext Story That will be the next mystic point. WCF, REST, JSON, ATOM and now OData. Nothing about SQL commands. LINQ, ORM is also not the final solution for multilayered disconnected async scenarios.

  • Is there an appropriate coding style for implementing an algorithm during an interview?

    - by GlenPeterson
    I failed an interview question in C years ago about converting hex to decimal by not exploiting the ASCII table if (inputDigitByte > 9) hex = inputDigitByte - 'a'. The rise of Unicode has made this question pretty silly, but the point was that the interviewer valued raw execution speed above readability and error handling. They tell you to review algorithms textbooks to prepare for these interviews, yet these same textbooks tend to favor the implementation with the fewest lines of code, even if it has to rely on magic numbers (like "infinity") and a slower, more memory-intensive implementation (like a linked list instead of an array) to do that. I don't know what is right. Coding an algorithm within the space of an interview has at least 3 constraints: time to code, elegance/readability, and efficiency of execution. What trade-offs are appropriate for interview code? How much do you follow the textbook definition of an algorithm? Is it better to eliminate recursion, unroll loops, and use arrays for efficiency? Or is it better to use recursion and special values like "infinity" or Integer.MAX_VALUE to reduce the number of lines of code needed to write the algorithm? Interface: Make a very self-contained, bullet-proof interface, or sloppy and fast? On the one extreme, the array to be sorted might be a public static variable. On the other extreme, it might need to be passed to each method, allowing methods to be called individually from different threads for different purposes. Is it appropriate to use a linked-list data structure for items that are traversed in one direction vs. using arrays and doubling the size when the array is full? Implementing a singly-linked list during the interview is often much faster to code and easier remember for recursive algorithms like MergeSort. Thread safety - just document that it's unsafe, or say so verbally? How much should the interviewee be looking for opportunities for parallel processing? Is bit shifting appropriate? x / 2 or x >> 1 Polymorphism, type safety, and generics? Comments? Variable and method names: qs(a, p, q, r) vs: quickSort(theArray, minIdx, partIdx, maxIdx) How much should you use existing APIs? Obviously you can't use a java.util.HashMap to implement a hash-table, but what about using a java.util.List to accumulate your sorted results? Are there any guiding principals that would answer these and other questions, or is the guiding principal to ask the interviewer? Or maybe this should be the basis of a discussion while writing the code? If an interviewer can't or won't answer one of these questions, are there any tips for coaxing the information out of them?

  • Identify memory leak in Java app

    - by Vincent Ma
    One important advantage of java is programer don't care memory management and GC handle it well. Maybe this is one reason why java is more popular. As Java programer you real dont care it? After you meet Out of memory you will realize it it’s not true. Java GC and memory is big topic you can get some information in here Today just let me show how to identify memory leak quickly. Let quickly review demo java code, it’s one kind of memory leak in our code, using static collection and always add some object. import java.util.ArrayList;import java.util.List; public class MemoryTest { public static void main(String[] args) { new Thread(new MemoryLeak(), "MemoryLeak").start(); }} class MemoryLeak implements Runnable { public static List<Integer> leakList = new ArrayList<Integer>(); public void run() { int num =0; while(true) { try { Thread.sleep(1); } catch (InterruptedException e) { } num++; Integer i = new Integer(num); leakList.add(i); } }} run it with java -verbose:gc -XX:+PrintGCDetails -Xmx60m -XX:MaxPermSize=160m MemoryTest after about some minuts you will get Exception in thread "MemoryLeak" java.lang.OutOfMemoryError: Java heap space at java.util.Arrays.copyOf(Arrays.java:2760) at java.util.Arrays.copyOf(Arrays.java:2734) at java.util.ArrayList.ensureCapacity(ArrayList.java:167) at java.util.ArrayList.add(ArrayList.java:351) at MemoryLeak.run(MemoryTest.java:25) at java.lang.Thread.run(Thread.java:619)Heap def new generation total 18432K, used 3703K [0x045e0000, 0x059e0000, 0x059e0000) eden space 16384K, 22% used [0x045e0000, 0x0497dde0, 0x055e0000) from space 2048K, 0% used [0x055e0000, 0x055e0000, 0x057e0000) to space 2048K, 0% used [0x057e0000, 0x057e0000, 0x059e0000) tenured generation total 40960K, used 40959K [0x059e0000, 0x081e0000, 0x081e0000) the space 40960K, 99% used [0x059e0000, 0x081dfff8, 0x081e0000, 0x081e0000) compacting perm gen total 12288K, used 2083K [0x081e0000, 0x08de0000, 0x10de0000) the space 12288K, 16% used [0x081e0000, 0x083e8c50, 0x083e8e00, 0x08de0000)No shared spaces configured. OK let us quickly identify it using JProfile Download JProfile in here  Run JProfile and attach MemoryTest get largest size of  Objects in Memory View in here is Integer then select Integer and go to Heap Walker. get GC Graph for this object  Then you get detail code raise this issue quickly now.  That is enjoy it.

  • Hardware and Software Working Together - What Does LJE say?

    - by Stephen Slade
     IDG News Service - Oracle CEO Larry Ellison said Oracle will continue to bet on selling high-end custom hardware for its software products, even amidst a growing trend toward roomfuls of cheap, generic servers. "You have to be in the hardware business and the software business, to get the best possible system," he said during a keynote speech at Oracle's OpenWorld conference in Tokyo. "We believe it's the right idea, we believe it's the next generation of computing, we believe all the pieces have to fit together." Ellison, as he has often done in the past, repeatedly referred to Apple as his "favorite example" of such tight integration. He was a close friend of Apple's co-founder Steve Jobs and previously served on Apple's board of directors.He said sales of Oracle's advanced servers were booming and generating around a billion dollars a year in revenue for the company, which has until recent years focused almost exclusively on its software offerings. With the explosion of popular online services and the increasing number of mobile devices that access them, demand is high for databases that can quickly respond to high numbers of relatively simple queries. While Oracle is pitching its expensive, finely-tuned machines to meet this requirement, Internet behemoths like Google, Facebook and Microsoft increasingly rely on armies of low-cost, easily replaceable servers. Ellison emphasized the high specifications of Oracle's servers, which come packed with multiple terabytes of RAM and flash-based storage for speed. Such machines are superior to large server farms, he said, because they require far less electricity and floor space, and are also cost competitive. When asked about whether purchasing such products would lock customers in to expensive hardware from Oracle, he promised that the company's software would always run on "multiple hardware sources."  Ellison, who spoke from Kyoto, Japan's ancient capital, was shown live online via webcast. The Oracle founder has a fondness for Japanese architecture and is staying in his large garden residence in the city Source: Ellison: Hardware-software integration key, Apple is best example. Oracle's founder and CEO reaffirmed his commitment to custom hardware for its software products  LINK to Computerworld article Apr 5, 2012 http://www.computerworld.com/s/article/9225858/Ellison_Hardware_software_integration_key_Apple_is_best_example?source=CTWNLE_nlt_entsoft_2012-04-09&utm_source=feedburner&utm_medium=feed&utm_campaign=Feed%3A+computerworld%2Fs%2Ffeed%2Ftopic%2F173+%28Computerworld+Databases+News%29#disqus_thread

  • Using lookahead assertions in regular expressions

    - by Greg Jackson
    I use regular expressions on a daily basis, as my daily work is 90% in Perl (legacy codebase, but that's a different issue). Despite this, I still find lookahead and lookbehind to be terribly confusing and often unreadable. Right now, if I were to get a code review with a lookahead or lookbehind, I would immediately send it back to see if the problem can be solved by using multiple regular expressions or a different approach. The following are the main reasons I tend not to like them: They can be terribly unreadable. Lookahead assertions, for example, start from the beginning of the string no matter where they are placed. That, among other things, can cause some very "interesting" and non-obvious behaviors. It used to be the case that many languages didn't support lookahead/lookbehind (or supported them as "experimental features"). This isn't the case quite as much, but there's still always the question as to how well it's supported. Quite frankly, they feel like a dirty hack. Regexps often already are, but they can also be quite elegant, and have gained widespread acceptance. I've gotten by without any need for them at all... sometimes I think that they're extraneous. Now, I'll freely admit that especially the last two reasons aren't really good ones, but I felt that I should enumerate what goes through my mind when I see one. I'm more than willing to change my mind about them, but I feel that they violate some of my core tenets of programming, including: Code should be as readable as possible without sacrificing functionality -- this may include doing something in a less efficient, but clearer was as long as the difference is negligible or unimportant to the application as a whole. Code should be maintainable -- if another programmer comes along to fix my code, non-obvious behavior can hide bugs or make functional code appear buggy (see readability) "The right tool for the right job" -- I'm sure you can come up with contrived examples that could use lookahead, but I've never come across something that really needs them in my real-world development work. Is there anything that they're really the best tool for, as opposed to, say, multiple regexps (or, alternatively, are they the best tool for most cases they're used for today). My question is this: Is it good practice to use lookahead/lookbehind in regular expressions, or are they simply a hack that have found their way into modern production code? I'd be perfectly happy to be convinced that I'm wrong about this, and simple examples are useful for examples or illustration, but by themselves, won't be enough to convince me.

  • Are there deprecated practices for multithread and multiprocessor programming that I should no longer use?

    - by DeveloperDon
    In the early days of FORTRAN and BASIC, essentially all programs were written with GOTO statements. The result was spaghetti code and the solution was structured programming. Similarly, pointers can have difficult to control characteristics in our programs. C++ started with plenty of pointers, but use of references are recommended. Libraries like STL can reduce some of our dependency. There are also idioms to create smart pointers that have better characteristics, and some version of C++ permit references and managed code. Programming practices like inheritance and polymorphism use a lot of pointers behind the scenes (just as for, while, do structured programming generates code filled with branch instructions). Languages like Java eliminate pointers and use garbage collection to manage dynamically allocated data instead of depending on programmers to match all their new and delete statements. In my reading, I have seen examples of multi-process and multi-thread programming that don't seem to use semaphores. Do they use the same thing with different names or do they have new ways of structuring protection of resources from concurrent use? For example, a specific example of a system for multithread programming with multicore processors is OpenMP. It represents a critical region as follows, without the use of semaphores, which seem not to be included in the environment. th_id = omp_get_thread_num(); #pragma omp critical { cout << "Hello World from thread " << th_id << '\n'; } This example is an excerpt from: http://en.wikipedia.org/wiki/OpenMP Alternatively, similar protection of threads from each other using semaphores with functions wait() and signal() might look like this: wait(sem); th_id = get_thread_num(); cout << "Hello World from thread " << th_id << '\n'; signal(sem); In this example, things are pretty simple, and just a simple review is enough to show the wait() and signal() calls are matched and even with a lot of concurrency, thread safety is provided. But other algorithms are more complicated and use multiple semaphores (both binary and counting) spread across multiple functions with complex conditions that can be called by many threads. The consequences of creating deadlock or failing to make things thread safe can be hard to manage. Do these systems like OpenMP eliminate the problems with semaphores? Do they move the problem somewhere else? How do I transform my favorite semaphore using algorithm to not use semaphores anymore?

  • SharePoint Designer 2010 Workflow Email Link To Item

    - by Brian Jackett
    In this post I’ll walk you through the process of sending an email that contains a link to the current item from a SharePoint Designer 2010 workflow.  This is a process that has been published on many other forums and blogs, but many that I have seen are more complex than seems necessary. Problem     A common request from SharePoint users is to get an email which contains a link to review/approve/edit the workflow item.  SharePoint list items contain an automatic property for Url Path, but unfortunately that Url is not properly formatted to retrieve the item if you include it directly on the message body.  I tried a few solutions suggested from other blogs or forums that took a substring of the Url Path property, concatenated the display form view Url, and mixed in some other strings.  While I was able to get this working in some scenarios I still had issues in general. Solution     My solution involved adding a hyperlink to the message body.  This ended up being far easier than I had expected and fairly intuitive once I found the correct property to use.  Follow these steps to see what I did.     First add a “Send an Email” action to your workflow.  Edit the action to pull up the email configuration dialog.  Click the “Add hyperlink” button seen below. When prompted for the address of the link click the fx button to perform a lookup.  Choose Workflow Context from the “data source” dropdown.  Choose Current Item URL from the “field from source” dropdown.  Click OK. Your Edit Hyperlink dialog should now look something like this. The end result will be a hyperlink added to your email pointing to the current workflow item.  Note: this link points to the non-modal dialog display form (display form similar to what you had in 2007). Conclusion     In this post I walked you through the steps to create a SharePoint Designer 2010 workflow with an email that contains a link to the current item.  While there are many other options for accomplishing this out on the web I found this to be a more concise process and easy to understand.  Hopefully you found this helpful as well.  Feel free to leave any comments or feedback if you’ve found other ways that were helpful to you.         -Frog Out

  • Getting WLAN on my Laptop to work (Medion MD98300)

    - by Anand Böhmer
    Dear Ubuntu Community, I am having difficulties to get the WLAN Adapter on my Medion 98300 Laptop to work. The WLAN Card seems to be connected through an internal USB Interface and the Card itself had shown up as a wirelles Network while installing Ubuntu. I have tried a few things earlier, but none of my google reasearches have brought me to a working solution... I am quite new to the Linux System and only knoew a couple of terminal commands so far, so I probably have missed out on a few possible solutions. Maybe you can help me? Thank you very much in advance! A fre minimal technical Details: AMD Turion 64 X2 Dual-Core Mobile Technolgie TL-50 NVIDIA GeForce Go 6150 SanDisk 64GB SSD 2GB RAM DDR2 667 nForce Chipset (I forgt the Version, but deductable from the GPU I guess) WiFi: ZyDAS ZD1211B 802.11g Thank's a lot again! :) UPDATE: I tried around myself a little and found a guide on the Linux Mint forums that helped! I already had tried to install the linux backport modules etc. What I finally did was update the linux firmware and run the following command: echo "options acer_wmi wirelles=1" sudo tee /etc/modprobe.d/acer_wmi.conf and rebooted now I found and could connect to networks, but unfortunately I found, that the link quality was very bad, around 40 to 50. Eventhough my Router is running at high power and is only 6 Meters away! I then switched a few channels, but that did not improve much. Before, under Windows, I had a very good link quality and had the entire 16mbit/s internet connection at disposal, now I can only get about 3-5Mbit/s. better then nothing, but still pretty bad! The "TX power" is fixed on 20dBm and iwconfig says, that the "Power Management" is off... Maybe the power of the module is set too low?... UPDATE2: I figured that 20dBm is a normal power output. I even tried to change the power using iwconfig wlan0 txpower INTEGERHERE but, obviously my "Card" does not support more then 20. More would probably be illegal as well, so I won't even use more then 20. I guess that I will have to figure out a way, or maybe just switch cards. Are the Mailboard-USB-Connectors on a laptop of the same property as the standard external ones? If so, I could simply solder a micro Wirelless N Adapter onto the board :)

  • Is there any good hosting for asp.net and MySQL

    - by HAJJAJ
    HI every one ,I have account with one of the hosting company, and i did my project in asp.net and I used MySQL for the database. the hosting company is not giving me the full privileges to create new user or to create new stored procedure!!! this is what they said for me: Due to the shared nature of our environment we had to make some modifications to your procedure (namely the definer). We also had to review your procedure to determine if it would be compatible with our environment. While your procedures will work (via phpMyAdmin or some other interface), it is unlikely they will be accessible via the Connector/.NET (ADO.NET) that your application is likely using. This is due to a security restriction with how that connector works in shared environments. http://dev.mysql.com/doc/refman/5.0/en/connector-net-programming-stored.html "Note When you call a stored procedure, the command object makes an additional SELECT call to determine the parameters of the stored procedure. You must ensure that the user calling the procedure has the SELECT privilege on the mysql.proc table to enable them to verify the parameters. Failure to do this will result in an error when calling the procedure." Unfortunately, giving read privileges on the mysql.proc table will give you access to the data of our other customers and that is not an acceptable risk. If your application can only work using stored procedures, then MSSQL will probably be the better option for your site. I apologize for the inconvenience and the wait to have this ticket completed. So is there any good hosting that any body already used it to publish his asp.net and mysql project ??? this is one of my stored procedure and i think it's sample and it will not harm any other uses!!: -- -------------------------------------------------------------------------------- -- Routine DDL -- Note: comments before and after the routine body will not be stored by the server -- -------------------------------------------------------------------------------- DELIMITER $$ CREATE DEFINER=`root`@`localhost` PROCEDURE `SpcategoriesRead`( IN PaRactioncode VARCHAR(5), IN PaRCatID BIGINT, IN PaRSearchText TEXT ) BEGIN -- CREATING TEMPORARY TABLE TO SAVE DATA FROM THE ACTIONCODE SELECTS -- DROP TEMPORARY TABLE IF EXISTS TEMP; CREATE temporary table tmp ( CatID BIGINT primary key not null, CatTitle TEXT, CatDescription TEXT, CatTitleAr TEXT, CatDescriptionAr TEXT, PictureID BIGINT, Published BOOLEAN, DisplayOrder BIGINT, CreatedOn DATE ); IF PaRactioncode = 1 THEN -- Retrive all DATA from the database -- INSERT INTO tmp SELECT CatID,CatTitle,CatDescription,CatTitleAr,CatDescriptionAr,PictureID,Published,DisplayOrder,CreatedOn FROM tbcategories; ELSEIF PaRactioncode = 2 THEN -- Retrive all from the database By ID -- INSERT INTO tmp SELECT CatID,CatTitle,CatDescription,CatTitleAr,CatDescriptionAr,PictureID,Published,DisplayOrder,CreatedOn FROM tbcategories WHERE CatID=PaRCatID; ELSEIF PaRactioncode = 3 THEN -- NOSET YET -- INSERT INTO tmp SELECT CatID,CatTitle,CatDescription,CatTitleAr,CatDescriptionAr,PictureID,Published,DisplayOrder,CreatedOn FROM tbcategories WHERE Published=1 ORDER BY DisplayOrder; END IF; IF PaRSearchText IS NOT NULL THEN set PaRSearchText=concat('%', PaRSearchText ,'%'); SELECT CatID,CatTitle,CatDescription,CatTitleAr,CatDescriptionAr,PictureID,Published,DisplayOrder,CreatedOn FROM tmp WHERE Concat(CatTitle, CatDescription, CatTitleAr, CatDescriptionAr) LIKE PaRSearchText; ELSE SELECT CatID,CatTitle,CatDescription,CatTitleAr,CatDescriptionAr,PictureID,Published,DisplayOrder,CreatedOn FROM tmp; END IF; DROP TEMPORARY TABLE IF EXISTS tmp; END
