• How to show pending messages using WLST?

  - by lmestre

  Here are the steps: 1. . ./setDomainEnv.sh2. java weblogic.WLST3. connect('weblogic','welcome1','t3://localhost:7001')4. domainRuntime()5. cd('ServerRuntimes/MS1/JMSRuntime/MS1.jms/JMSServers/JMSServer1/Destinations/JMSModule1!Queue1')6. cursor1=cmo.getMessages('true',9999999,10)                                                 **String(selector),Integer(timeout),Integer(state)7. msgs = cmo.getNext(cursor1, 10)                  ** This step gets 10 messages, you can call again cmo.getNext(cursor1, 10) to get the next 10 msgs8. print(msgs)My assumption, is that you had created:a. Managed Server MS1.b. JMS Server JMSServer1.c. Module called JMSModule1.d. Inside of JMSModule1, a Queue called Queue1.If you read my previous post:How to get Messages Pending Count from a Queue using WLST? https://blogs.oracle.com/LuzMestre/entry/how_to_get_messages_pendingYou can see that both are very similar.  Sometimes it is difficult to get a WLST Script sample, but you can use ls() function to know about other functionalities you don't have a sample code.***Until step 5, nothing new comparing to my previous post.5. cd('ServerRuntimes/MS1/JMSRuntime/MS1.jms/JMSServers/JMSServer1/Destinations/JMSModule1!Queue1')6. ls()You will see, MessagesPendingCount, getMessages along a lot of other functionalities available in this Queue. e.g, you can see:-r-x   getMessages                                  String : String(selector),Integer(timeout),Integer(state)Here you can check the complete MBean Reference:http://docs.oracle.com/cd/E23943_01/apirefs.1111/e13951/core/index.htmlSee JMSDestinationRuntimeMBean.Enjoy!

• Java - Draw Cards and Eliminate Cards Problem

  - by Jen

  I am having a problem in this question. I want a system inside a game wherein the player draws 2 cards randomly, and the enemy draws 2 cards randomly. Then, what the program does is to print out to the console the cards the player draw and the enemy's. The cards should not conflict and must not be the same. Then lastly, the program prints out the card that was not drawn by both the player and the enemy. Here's how I did it but it was lengthy and full of errors: import java.util.Random; public class Draw { public static Random random = new Random(); public static String cards[] = {"Hall", "Kitchen", "Billiard", "Study", "Pool"}; public static int playercounter; public static int enemycounter; public static String playercardA = null; public static String playercardB = null; public static String enemycardA = null; public static String enemycardB = null; public String lastcard = null; public static void playercardAdraw() { playercounter = random.nextInt(5); playercardA = cards[playercounter]; } public static void playercardBdraw() { playercounter=random.nextInt(5); playercardB= cards[playercounter]; if (playercardB==playercardA || playercardB == enemycardA || playercardB == enemycardB) { return; } } public static void enemycardAdraw () { enemycounter = random.nextInt(5); enemycardA=cards[enemycounter]; if (enemycardA == playercardA || enemycardA == playercardB) { return; } } public static void enemycardBdraw () { enemycounter = random.nextInt(5); enemycardB=cards[enemycounter]; if (enemycardB == playercardA || enemycardB == playercardB || enemycardB == enemycardA) { return; } } public static void main (String args []) { System.out.println("Starting to draw..."); System.out.println("Player's Turn: "); playercardAdraw(); System.out.println("Player's first card: " + playercardA); playercardBdraw(); System.out.println("Player's second card: " + playercardB); System.out.println("Enemy's Turn: "); enemycardAdraw(); System.out.println("Enemy's first card: " + enemycardA); enemycardBdraw(); System.out.println("Enemy's Second card: " + enemycardB); } }

• Nashorn in the Twitterverse

  - by jlaskey

  I have been following how often Nashorn has been showing up on the net.  Nashorn got a burst of tweets when we announced Project Nashorn and I was curious how Nashorn was trending per day, maybe graph the result.  Counting tweets manually seemed mindless, so why not write a program to do the same. This is where Nashorn + Java came shining through.  There is a very nice Java library out there called Twitter4J https://github.com/yusuke/twitter4j that handles all things Twitter.  After running bin/getAccessToken.sh to get a twitter4j.properties file with personal authorization, all I had to do to run my simple exploratory app was; nashorn -cp $TWITTER4J/twitter4j-core-3.0.1.jar GetHomeTimeline.js The content of GetHomeTimeline.js is as follows; var twitter4j      = Packages.twitter4j; var TwitterFactory = twitter4j.TwitterFactory; var Query          = twitter4j.Query; var twitter = new TwitterFactory().instance; var query   = new Query("nashorn OR nashornjs"); query.count = 100; do {     var result = twitter.search(query);     var tweets = result.tweets;     for each (tweet in tweets) {         print("@" + tweet.user.screenName + "\t" + tweet.text);     } } while (query = result.nextQuery()); How easy was that?  Now to hook it up to the JavaFX graphing library...

• Small script to look for Project Replication actions that have failed

  - by Trond Strømme

  Today when looking at a couple of projects on a ZFS 7320 Storage Appliance I noticed on one project that one of its replication actions had failed, as I hadn't checked the Recent Alerts log yet I was not aware of this. I decided to write a small script to check if there were others that had failed. Nothing fancy, just a loop through all projects, look at the project's replication child and compare the values of the last_sync and last_try properties and print the result if they're not equal. (There are probably more sensible ways of doing this, but at least it involves me getting the chance to put on my headphones and doing just a little bit of coding.) script // this script will locate failed project level replication // it will look at the sync times for 'last_sync' and 'last_try' // and compare these, if they deviate you should investigate. // NOTE! this code is offered 'as is' Run at your own risk, // it will probably work as intended, but in now way can I // (or Oracle) be held responsible if your server starts behaving // like a three year old kid in a candy store.. (not that mine do, // they are very well behaved boys...) run('configuration'); run('storage'); printf('Host: %s, pool: %s\n', get('owner'),get('pool')); run('cd /'); run('shares'); proj=list(); printf("total projects: %d\n",proj.length +'\n'); // just for project level replication for(i=0;i<proj.length;i++){ run('select '+proj[i]); run('replication'); //get all replication actions preps = list(); for(j=0;j<preps.length;j++){ run('select ' + preps[j]); last_sync = get('last_sync'); last_try = get('last_try'); // printf("target %s\n", get('target')); //why the flip does this not get the proper name? if(!( last_sync.valueOf() === last_try.valueOf())){ printf("sync has failed for %s %s\n", proj[i], get('target')); }else{ // printf("OK %s %s\n", proj[i], get('target')); } run('done'); //done with the replica action } run('done'); run('done'); } printf("finished\n"); For a more on how to run the script, or testing it please look at my previous post. Sample output: Host: elb1sn01, pool: exalogic total projects: 45 sync has failed for ACSExalogicSystem cb3a24fe-ad60-c90f-d15d-adaafd595639 finished

• PASS Summit Location follow up - result analysis

  - by simonsabin

  I've had a chance to look at the results directly and it is clear that there is a tough choice. On the one hand people are saying that they prefer to have PASS put their money into chapters and things like 24hrs of PASS rather than an event on the east coast. Whilst at the same time almost 50% more people said they would be more likely to attend an East Coast event than a Seattle event, and 60% more said they would be more likley to attend a US Central region event. Whats more 60% said that the summit should be outside of Seattle every other year with only 19% saying it should always stay in Seattle. So clearly there is a huge desire for a non Seattle event. Looking at the other reasons for keeping in Seattle and the big one being that people want Microsoft speakers. More people think its somewhat important of very important that the conference is in walking distance of the hotels and restaurants. Essentially the Q6 questions show an even balance for normal conference, highlighting that they are prepared to travel, not with the family and they want a well laid out conference. Whats very annoying is that the questions, as people have commented, were biased towards certain answers. For instance there was no option about whether people feel its important to have industry leading speakers, MVPs etc at the conference. Only questions about Microsoft speakers. I know survey writing is very difficult to avoid biasing the answers one way or another. There was also no choice to show peoples preference, would people prefer Microsoft speakers or the summit to be held on the East Coast/Central US. I also find it amazing that people prefer hundres of developers rather than the SQLCAT and CSS teams, surely that indicates another issue about a lack of understanding of what the these teams do. All in all it is clear that people showed they want an event outside of Seattle and don't want PASS to be putting money into that instead of into other community activites. I find it suprising that there appears to have been a huge weighting against certain questions which have prioritised them over the huge desire for a PASS summit outside of Seattle. Lets see where we will be in 2013 or maybe they will rethink 2012 who knows.

• Image first loaded, then it isn't? (XNA)

  - by M0rgenstern

  I am very confused at the Moment. I have the following Class: (Just a part of the class): public class GUIWindow { #region Static Fields //The standard image for windows. public static IngameImage StandardBackgroundImage; #endregion } IngameImage is just one of my own classes, but actually it contains a Texture2D (and some other things). In another class I load a list of GUIButtons by deserializing a XML file. public static GUI Initializazion(string pXMLPath, ContentManager pConMan) { GUI myGUI = pConMan.Load<GUI>(pXMLPath); GUIWindow.StandardBackgroundImage = new IngameImage(pConMan.Load<Texture2D>(myGUI.WindowStandardBackgroundImagePath), Vector2.Zero, 1024, 600, 1, 0, Color.White, 1.0f, true, false, false); System.Console.WriteLine("Image loaded? " + (GUIWindow.StandardBackgroundImage.ImageStrip != null)); myGUI.Windows = pConMan.Load<List<GUIWindow>>(myGUI.GUIFormatXMLPath); System.Console.WriteLine("Windows loaded"); return myGUI; } Here this line: System.Console.WriteLine("Image loaded? " + (GUIWindow.StandardBackgroundImage.ImageStrip != null)); Prints "true". To load the GUIWindows I need an "empty" constructor, which looks like that: public GUIWindow() { Name = ""; Buttons = new List<Button>(); ImagePath = ""; System.Console.WriteLine("Image loaded? (In win) " + (GUIWindow.StandardBackgroundImage.ImageStrip != null)); //Image = new IngameImage(StandardBackgroundImage); //System.Console.WriteLine( //Image.IsActive = false; SelectedButton = null; IsActive = false; } As you can see, I commented lines out in the constructor. Because: Otherwise this would crash. Here the line System.Console.WriteLine("Image loaded? (In win) " + (GUIWindow.StandardBackgroundImage.ImageStrip != null)); Doesn't print anything, it just crashes with the following errormessage: Building content threw NullReferenceException: Object reference not set to an object instance. Why does this happen? Before the program wants to load the List, it prints "true". But in the constructor, so in the loading of the list it prints "false". Can anybody please tell me why this happens and how to fix it?

• preview form using javascript in popup

  please I need some help in previewing a form in popup. I have a form, quite big, so I added the option of preview to show as popup. The lightbox form popup works well, but the problem I now have is function passform ()passing the inputs(textfield, select, checkbox, radio) into the popup page for preview on Click(). Below are my javascript and html codes. I left the css and some html out, because I think they're not needed. I will appreciate your help.

• Java word scramble game [closed]

  - by Dan

  I'm working on code for a word scramble game in Java. I know the code itself is full of bugs right now, but my main focus is getting a vector of strings broken into two separate vectors containing hints and words. The text file that the strings are taken from has a colon separating them. So here is what I have so far. public WordApp() { inputRow = new TextInputBox(); inputRow.setLocation(200,100); phrases = new Vector <String>(FileUtilities.getStrings()); v_hints = new Vector<String>(); v_words = new Vector<String>(); textBox = new TextBox(200,100); textBox.setLocation(200,200); textBox.setText(scrambled + "\n\n Time Left: \t" + seconds/10 + "\n Score: \t" + score); hintBox = new TextBox(200,200); hintBox.setLocation(300,400); hintBox.hide(); Iterator <String> categorize = phrases.iterator(); while(categorize.hasNext()) { int index = phrases.indexOf(":"); String element = categorize.next(); v_words.add(element.substring(0,index)); v_hints.add(element.substring(index +1)); phrases.remove(index); System.out.print(index); } The FileUtilities file was given to us by the pofessor, here it is. import java.util.*; import java.io.*; public class FileUtilities { private static final String FILE_NAME = "javawords.txt"; //------------------ getStrings ------------------------- // // returns a Vector of Strings // Each string is of the form: word:hint // where word contains no spaces. // The words and hints are read from FILE_NAME // // public static Vector<String> getStrings ( ) { Vector<String> words = new Vector<String>(); File file = new File( FILE_NAME ); Scanner scanFile; try { scanFile = new Scanner( file); } catch ( IOException e) { System.err.println( "LineInput Error: " + e.getMessage() ); return null; } while ( scanFile.hasNextLine() ) { // read the word and follow it by a colon String s = scanFile.nextLine().trim().toUpperCase() + ":"; if( s.length()>1 && scanFile.hasNextLine() ) { // append the hint and add to collection s+= scanFile.nextLine().trim(); words.add(s); } } // shuffle Collections.shuffle(words); return words; } }

• Determining cause of random latency/loading issues

  - by Sherwin Flight

  I'm not sure exactly what details to post in regards to my issue, because I'm not sure what is relevant. Prior to the end of September my websites all loaded quickly, in almost all cases. Loading time wasn't usually more than a few seconds. However, since the end of September I noticed a big increase in page loading times. In some cases pages were taking 30 seconds or more to load. I do have a remote monitoring service monitoring some of the sites as well, and the image below shows the response times over the past month. The response times shown at the beginning of this graph were what the usual response times were prior to this issue occurring. You can see that there has been a significant increase in response times from the beginning to the end of this graph. The thing is, the problem is not happening 100% of the time. If I click through the site, or even just keep refreshing the page, about 25% of the time the pages load quickly, the remaining 75% of the time they load slowly. Sometimes the pages take so long to load that they time out, and don't load at all. I have contacted my hosting provider, and they said things at their end was fine. I don't believe the problem is my home internet provider, because all other websites load without a problem. The server is located in Texas, USA. This also raises another interesting point. My remote monitor checks my site from two locations, California, USA, and London, England. As you can see in the chart below the response time is actually shorter when checked from London, which doesn't seem to make sense, since the server is physically closer to the California monitoring location. I would have expected the London monitoring location to have higher response times since they are physically farther away. I should also point out that in some traceroute test I've done it seem like the first connection to the server seems to take the longest, then after that the rest of the page loads quickly. Below is a little chart showing the times for the first connection to the server. So, what could be causing this problem, and what steps can I take to resolve it or at least narrow down the problem? Sending the request to the server was very quick, and receiving the reply back seems pretty quick, but the WAIT time is really long. So it connects, sends the request, but then waits close to 30 seconds before it starts receiving data back. I am also aware that there are things I can do to speed up page loading times, like reducing the number of css/js files used on a page, compressing images, etc. This is not really what the source of the problem is though, because nothing has really changed on the site since before the problem started, and other sites on the same server are loading slowly as well. Any help or advice is much appreciated.

• How should I land my next consulting gig? [closed]

  - by MrOodles

  For the last couple of years, I've been working on speculative projects, expanding my skillset with side work, and paying the bills while having a blast consulting for startups. However, for a number of personal reasons, I need to spend the next 6-9 months maximizing my cash income. I want to put this into effect starting in early August. So that means I have one month to put the necessary client list/portfolio/resume together to start making this happen. As a programmer, I am very proficient in building Django web apps. I can write the necessary SQL, python, javascript, and css to build every part of a Django app, and then do the system administration necessary to deploy on AWS using EC2. I can also rig up a CDN to work seemlessly with the app using S3 and Cloudfront. I have built GIS applications using GeoDjango and PostGIS, and I have constructed social video apps by implementing Encoding.com as a service to prepare raw video files for consumption on the web. I am also moderately proficient in programming PHP, Java, and C#. I have built web apps in PHP, and desktop apps in Java and C#. I have dabbled with Android applications and iPhone apps, but nothing I would show off. I have experience doing SEO, social media marketing, and content marketing. Many of my clients have needed their apps promoted after they were built, and I was always happy to oblige when I could. I have also worked with biometrics technology including fingerprints for government contractors. This was as much a business analyst role as it was a programming gig, as I had to help answer RFPs, make checklists, and work around reems and reems of regulations to build applications that met very large bureaucratic requirements. I only have two real requirements for my next gig(s): 1) Work remotely. I live in North East Ohio, and I don't plan on leaving, but I wouldn't mind traveling one or two weeks out of every month to service clients who need on-site help. 2) $60.00hr-$∞ USD contracting rate. So what should I do for the next 30 days to achieve this? Should I target some large company and learn the requisite buzzwords to impress them? Should I learn some new language or technology? Polish some skill that I already have? Should I build something using my current skillset, or with some new technology? Should I put a website for my consultancy together to market myself? Should I do that using latest technology x, y, and z? Or should I just slap something up on Tumblr? I'm willing to do anything (moral) over the next 4 weeks to put myself into a position to maximize my income, and I'm open to all and every idea Programmers users may have. Let me hear them.

• Looking for recommendations for a server-side newsletter program

  - by Sparky672

  Hello- I'm currently using a server-side SQL based mailing list program called Php-List on multiple sites and it works fairly well. But installation and setup is quite cumbersome, quirky and the interface is not well organized... neither is the code... with pieces all over the place in random fashion. Customizing the "look & feel" and full site integration are both tedious and painful. Upgrading the version is made more complex since multiple edits need to be manually transferred each time. Also, probably due to a poor English translation, descriptions and instructions within certain areas of the user interface are contradictory and unclear. You just have to play with it and remember what you did last time it worked. It's supposed to be so my customers can send out their own newsletters... after supplying a written tutorial, about half of them seem to stumble through it okay and the other half just hire me to do it for them. So not quite easy enough for most average people to use. I'm looking for something that's as easy for them as using a blog or discussion forum. It also must be easier to set up and integrate into a site than Php-List. I have no problem getting dirty and writing CSS or HTML by hand. Nor do I have any problem editing the program code. Perhaps what I'm looking for is a solution that is more organized, a better GUI, and template or "skin" based. Therefore, if I spend many hours customizing a skin, I can simply update the program and re-use my custom skin without having to reproduce the tedious setup over and over. (I currently maintain a list of about 25 things I must manually edit or add to multiple files in multiple directories each time I install or upgrade Php-List) A great example of what I'm looking for is very much like WordPress or phpBB. They're both easy to install and customize yet powerful and packed full of features. They're also VERY well organized making customization less painful. So enough yammering for now... anyone know of something, besides Php-List, with many of the same features as Php-List; maintaining a mailing list with a server-side database, custom sign-up pages, automatic opt-in opt-out, allowing custom HTML newsletter templates, etc? Thank-you!

• Weird Ubuntu Desktop Boot Partition On External Hard Drive

  - by Magnitus

  I have a Thinkpad with Windows 7. Last time I installed an Ubuntu/Windows dual boot, Windows was never same after and regularly got corrupted so this time, I installed Ubuntu on a separate external hard drive. I took a 500 GB external hard drive and used Windows to shrink the partition on it to 400 GB, freeing 100 GB to install Ubuntu. Then I modified the booting priority of my computer to boot from the external hard drive if present. Then, I installed Ubuntu desktop on the external hard drive using a DVD, picked the most simplistic partitioning scheme I could get away with (didn't go auto as it didn't include the external hard drive as a choice) and voilà. Fast forward some time and I'm trying to refresh my understanding of Linux partitions to install a bunch of servers, so I'm looking at the current partitioning scheme on my external hard drive and find the boot partition puzzling... sda is my integrated hard drive with Windows 7. sdb is my Ubuntu desktop external hard drive. Running parted on sdb, I get this: (parted) print Model: WD My Passport 0740 (scsi) Disk /dev/sdb: 500GB Sector size (logical/physical): 512B/512B Partition Table: msdos Number Start End Size Type File system Flags 1 1049kB 393GB 393GB primary ntfs boot 2 393GB 500GB 107GB extended 5 393GB 425GB 32.8GB logical linux-swap(v1) 6 425GB 500GB 74.6GB logical ext4 At this point, I'm wondering why the ntfs partition is flagged as "boot" and not my ext4 partition which is the partition that contains / (and by extension, /boot since it's not on its own separate partition). Looking at mtab only confirms what I already know: eric@eric-ThinkPad-W530:~$ sudo cat /etc/mtab /dev/sdb6 / ext4 rw,errors=remount-ro 0 0 proc /proc proc rw,noexec,nosuid,nodev 0 0 sysfs /sys sysfs rw,noexec,nosuid,nodev 0 0 none /sys/fs/cgroup tmpfs rw 0 0 none /sys/fs/fuse/connections fusectl rw 0 0 none /sys/kernel/debug debugfs rw 0 0 none /sys/kernel/security securityfs rw 0 0 udev /dev devtmpfs rw,mode=0755 0 0 devpts /dev/pts devpts rw,noexec,nosuid,gid=5,mode=0620 0 0 tmpfs /run tmpfs rw,noexec,nosuid,size=10%,mode=0755 0 0 none /run/lock tmpfs rw,noexec,nosuid,nodev,size=5242880 0 0 none /run/shm tmpfs rw,nosuid,nodev 0 0 none /run/user tmpfs rw,noexec,nosuid,nodev,size=104857600,mode=0755 0 0 none /sys/fs/pstore pstore rw 0 0 systemd /sys/fs/cgroup/systemd cgroup rw,noexec,nosuid,nodev,none,name=systemd 0 0 gvfsd-fuse /run/user/1000/gvfs fuse.gvfsd-fuse rw,nosuid,nodev,user=eric 0 0 /dev/sdb1 /media/eric/My\040Passport fuseblk rw,nosuid,nodev,allow_other,default_permissions,blksize=4096 0 0 My lack of understanding concerning this is not vital to anything (this is only my development desktop partition), but somehow annoys me. Any insight that could shed some light on this would be welcome.

• Pixels - A cry for some insight

  - by CarrotFile

  I'm pretty new to web developing and I'd love some clarification. Although reading more than one book on the topic, I cannot seem to wrap my head around the pixel concept. I encounter problems with this issue when trying to use CSS and pixel units for design that fits different screen sizes. To my understanding a pixel is the most basic unit used by a monitor in order to compose an image on the screen. So if me resolution is 800 by 600, everything on my screen is rendered using those 800*600 basic building blocks. If I were to enlarge my screen resolution, 3 things would accrue: A. The basic image building block(the pixel) would shrink in size B. The pixels would move close together C. Well, more pixels would now be available All these combined lead to a sharper(depending on the viewing distance) and more detail enabling image. Well so far so good. Here is were I start getting lost: To my knowledge a pixel is not a physical, real object. Monitors are not embedded with a few thousand pixels. I am drawn to this conclusion because anyone can change his screen's resolution, making a pixel on his screen bigger or smaller, and adding or subtracting the amount of total pixels on screen. Adding to that, I have herd that different monitors have different pixel densities. For example Apple's retina monitors. Taking all of the above as my knowledge base, These are my questions: If a pixel has no real world constant size, what does comparing different pixel densities matter? Each screen company can define it's own pixel concept and declare the higher density. What does a bigger pixel density mean? Say we take two screens with the same physical dimensions, but with a different pixel density, am I to assert that the main difference would be the larger density screen being able to display a higher max resolution? Or am I to assert that given the same resolution on both monitors, the higher density one would display a sharper, smaller image? If a pixel is not a fixed size within one monitor, is it a fixed size between the same resolution on two different monitors? For example, would two different monitors, set to the same resolution, be comprised of same size, same quantity pixels? I'd love some help (:

  - by MCSell

  I got the following code: <div data-role="content" height="100%" data-iscroll> <div class="homebutton_zeile"> <a id="picture_home" href="#pictrues"> <div class="homebutton_all"> <div class="homebutton_name">Picture</div> <div class="homebutton_picture"> <img src="images/picture.png" alt="image" style="position: relative;"> </div> </div> </a> </div> </div> </div> My Classes of CSS .homebutton_zeile{ width: 100%; height: 30%; } .homebutton_all{ width: 30%; height: 90%; float:left; margin-left: 2%; margin-top:15px; } .homebutton_picture{ position: relative; width: 100%; height: 85%; float: left; background-color: #AAC7BD; border: 1px solid black; border-radius: 15px; box-shadow:8px 8px 8px #666; } .homebutton_name{ text-align:center; position: relative; top:-10px; width: 100%; height: 15%; margin-left: auto; text-decoration:none; color:black; } I am Using: iscroll.js jquery 1.8.2 jquery mobile 1.2.0 jqery mobile iscrollview. And if its needed to know jstorage.js and fastclick.js But the div above is not getting a height at the wrapper of iscroll. There is also a login before and this page will be shown automatically after the login after a $.mobile.changePage("#home"); function. I tried to do it as first page before the function of changePage and it gave me the same effect. If i put a   for example after the <div data-role="content" height="100%" data-iscroll>&nbps; The Wrapper get a height of 15px for the &nbps; but not for the images inside.

• StringBuffer behavior in LWJGL

  - by Michael Oberlin

  Okay, I've been programming in Java for about ten years, but am entirely new to LWJGL. I have a specific problem whilst attempting to create a text console. I have built a class meant to abstract input polling to it, which (in theory) captures key presses from the Keyboard object and appends them to a StringBuilder/StringBuffer, then retrieves the completed string after receiving the ENTER key. The problem is, after I trigger the String return (currently with ESCAPE), and attempt to print it to System.out, I consistently get a blank line. I can get an appropriate string length, and I can even sample a single character out of it and get complete accuracy, but it never prints the actual string. I could swear that LWJGL slipped some kind of thread-safety trick in while I wasn't looking. Here's my code: static volatile StringBuffer command = new StringBuffer(); @Override public void chain(InputPoller poller) { this.chain = poller; } @Override public synchronized void poll() { //basic testing for modifier keys, to be used later on boolean shift = false, alt = false, control = false, superkey = false; if(Keyboard.isKeyDown(Keyboard.KEY_LSHIFT) || Keyboard.isKeyDown(Keyboard.KEY_RSHIFT)) shift = true; if(Keyboard.isKeyDown(Keyboard.KEY_LMENU) || Keyboard.isKeyDown(Keyboard.KEY_RMENU)) alt = true; if(Keyboard.isKeyDown(Keyboard.KEY_LCONTROL) || Keyboard.isKeyDown(Keyboard.KEY_RCONTROL)) control = true; if(Keyboard.isKeyDown(Keyboard.KEY_LMETA) || Keyboard.isKeyDown(Keyboard.KEY_RMETA)) superkey = true; while(Keyboard.next()) if(Keyboard.getEventKeyState()) { command.append(Keyboard.getEventCharacter()); } if (Framework.isConsoleEnabled() && Keyboard.isKeyDown(Keyboard.KEY_ESCAPE)) { System.out.println("Escape down"); System.out.println(command.length() + " characters polled"); //works System.out.println(command.toString().length()); //works System.out.println(command.toString().charAt(4)); //works System.out.println(command.toString().toCharArray()); //blank line! System.out.println(command.toString()); //blank line! Framework.disableConsole(); } //TODO: Add command construction and console management after that } } Maybe the answer's obvious and I'm just feeling tired, but I need to walk away from this for a while. If anyone sees the issue, please let me know. This machine is running the latest release of Java 7 on Ubuntu 12.04, Mate desktop environment. Many thanks.

• Advice on how to build html5 basic tile game (multi player, cross device)

  - by Eric

  I just read http://buildnewgames.com/real-time-multiplayer/ which explains the fundamentals and bets practices to build a massive real time multiplayer html5 game. My question is however given the “simplicity” of the game I need to build (simple kind of scratch game where you find or not something behind a tile), do I really need complex tools (canvas or node.js for example) ? The game The gamestakes place with a picture of our office as a background (tilemap). For HR purpose, we wish to create the following game fore employees: each day they can come to the website and click on a certain number of tiles (3 max per day) and find behind it motivation advice and interesting facts about the company. The constraints and rules the screen is divided into isometric 2D square tiles. There are basically an image (photograph of our office) number of tiles on the screen game: about 10,000 to much more (with scroll , see below) the players can scroll in 4 directions there are only 2 types of tiles: already open and closed player can open tiles that have not been yet open by other players there is no path for players : any player can click on any tile on the screen at any moment (if it’s not already done by another player) 2 players can’t be on the same tile at the same moment (or if they can, I’ll have to manage to see which one clicked on it first) only one type of player (all with similar roles), no weapon, no internal score… very simple game. no complex physics (collision only occurs if 2 players are on the same tile) The target I need to achieve: cross device, cross browsers high performance reaction (subsecond reactions) average nb of players per hour: up to 10K players per hour (quite high indeed but it’s because we aim at proving our case for the game to our business unit) So what I would like to know: 2D Tiled map: Do I need tiledmapeditor or can I enable me split the screen like here ? should I use canvas or plain html/css could be sufficient for my need? do I need a game engine/framework such as melon.js or crafty./js ? (even if the game play is extremely basic, I do need mouse and touché device support, mouse emulations on touch devices…) or ca I easily/quickly do it without? for my constraints and targets, should I use CPU acceleration ? for my constraints and targets, should I use web workers ? for the database, for a massively real time game should I avoid to put the current locations of player in MySQL as i feel it might slow me down. What kind of DB should I implement ? Thanks for your help !

• Website directory structure regarding subdomains, www, and "global" content

  - by Pawnguy7

  I am trying to make a homemade HTTP server. It occurs to me, though, I never fully understood what you might call "relativity" among web pages. I have come across that www. is a subdomain, and I understand its original purpose. IT sounds like, in general, you would redirect (is that 301 or 302?) it to a... non-subdomain, sort of. As in, redirecting www.example.com to example.com. I am not entirely sure how to make this work when retrieving files for an HTTP server though. I would assume that example.com would be the root, and www manifests as a folder within it. I am unsure. There is also the question of multi-level subdomains, e.g. subdomain2.subdomain1.example.com. It seems to me they are structured "backwards", where you go from the root left in folder structure. In this situation, subdomain2 is a directory within subdomain1, which is a directory in the root. Finally, it occurs to me I might want a sort of global location. For example, maybe all subdomains still use an image as a logo. It makes more sense to me that there is one image, rather than each having a copy. In the same way, albiet more doubtfully, you might have global CSS (though that is a bit contrary to the idea of a subdomain in the first place), or a javascript that is commonly used. (more efficient than each having its copy and better for organization purposes). Finally, mabye you have a global 404 page. I think this might be the case where you have user-created subdomains (say bloggername.example.com), where example.com still has a default 404 when either a subdomain does not exist or page does not exists under a valid blogger. I am confused on what the directory structure for this should be. To summarize: Should and how it have a global files not in a subdirectory, how should www. be handled, (or how a now www or other subdomain should be handled), and the pattern for root/subdomain, as well as subdomain within subdomains (order-wise). Sorry this is multiple questions, but I feel at the root they are all related to the directory.

• MOSSt 2010 Hosting :: Dialog Platform in SharePoint 2010 & How to Open the Edit Form Dialog for List Item

  - by mbridge

  One of the New User Interface Platforms in SharePoint 2010 is ‘The Dialog Platform’ A dialog is essentially a <div> which gets visible on demand and renders the HTML using a background overlay creating a modal dialog like user experience. We can show an existing div from within the page or a different page using a URL inside the dialogs. When we pass the URL to the dialog it looks for the Querystring parameter “IsDlg=1”. If this parameters exists than it would dynamically load the "/_layouts/styles/dlgframe.css” file. This file overrides the “s4-notdlg” class items as “display:none”, which means that all items with this class would not get displayed in Dialog Mode.  So if we go to the v4.master page we can see that this class is used by the Ribbon control to hide the ribbon when in dialog mode: How to open the Edit Form Dialog for List Item: In SharePoint 2010 The URL for opening the Edit Form of any list item looks like something like this : http://intranet.contoso.com/<SiteName>/Lists/<ListName>/EditForm.aspx?ID=1&IsDlg=1 ID is the list item row identifier and as discussed above the IsDlg is for the dialog mode. Now to open a dialog we need to use the SP.UI.ModalDialog.showModalDialog method from the ECMAScript Client Object model and pass in the url of the page, width & height of the dialog and also a callback function in case we want some code to run after the dialog is closed. <script type="text/javascript">          //Handle the DialogCallback callback               function DialogCallback(dialogResult, returnValue){               }             //Open the Dialog           function OpenEditDialog(id){             var options = { url:&quot;http://intranet.contoso.com/<SiteName>/Lists/<ListName>/EditForm.aspx?ID=&quot; + id + &quot;&amp;IsDlg=1&quot;,              width: 700,              height: 700,              dialogReturnValueCallback: DialogCallback              };             SP.UI.ModalDialog.showModalDialog(options);           } </script> The .js files for the ECMAScript Object Model (SP.js, SP.Core.js, SP.Ribbon.js, and SP.Runtime.js ) are installed in the %ProgramFiles%\Common Files\Microsoft Shared\web server extensions\14\TEMPLATE\LAYOUTS directory. Here is a good MSDN link explaining the Client Object Model Distribution and Deployment options available in SharePoint 2010 and this is the lowest costSharePoint 2010 Provider.

• iPhone app development pricing [closed]

  - by AlexMorley-Finch

  I currently manage a website design and development company that integrates itself with print work too. I've been co manager for a couple of months now, however business is slow at the moment. I got an email today from a potential client asking if we do iPhone app development. Obviously we do not. But, seeing as there aren't many other project on the go at the moment, why not give it a go? Searching Google was my first option. I did a bit of background scrubbing. Discovered that I need certain developer tools etc. This can be arranged easily enough. The reason I came to Stack Exchange is for answers to these questions. I am a competant programmer and have had experience in Java, PHP, JavaScript, C++ and C#. So how long would it take me to come to grips with Objective-C? Assuming an 8 hour working day. Not only the language but also the iPhone interface libraries (if any exist) and other native libraries? The potential client said the app will be a catalogue. So I'm assuming either the data will be pulled online or in some kind of local database. I know the requirements are vague but does anyone have any idea of how mug time this would take? To learn the language, design the architecture and code? 40 Hours? 80 Hours? My final question kind of depends on the first two. But obviously the potential client wants a quote. And I have got no idea how much an app costs. I did some research and found a huge range in differences. The majority of the cost would cone from the time to develops the app! So to summarise. How long would it take me to be comfortable coding Objective-C, taking into consideration my past knowledge? I'm assuming a day or two to fully understand but you really don't know. How long would it take me to develop an app? How much should I charge (approx) for the development of this app?

• The type of programmer I want to be [closed]

  - by Aventinus_

  I'm an undergraduate Software Engineer student, although I've decided that pure programming is what I want to do for the rest of my life. The thing is that programming is a vast field and although most of its aspects are extremely interesting, soon or later I'll have to choose one (?) to focus on. I have several ideas on small projects I'd like to develop this summer, having in mind that this will gain me some experience and, in the best scenario, some cash. But the most important reason I'd like to develop something close to “professional” is to give myself direction on what I want to do as a programmer. One path is that of the Web Programmer. I enjoy PHP and MySQL, as well as HTML and CSS, although I don't really like ASP.NET. I can see myself writing web apps, using the above technologies, as well as XML and Javascript. I also have a neat idea on a Facebook app. The other path is that of the Desktop Programmer. This is a little more complicated cause I really-really enjoy high level languages such as Java and Python but not the low level ones, such as C. I use both Linux and Windows for the last 6 years and I like their latest DEs (meaning Gnome Shell and Metro). I can see myself writing desktop applications for both OSs as long as it means high level programming. Ideally I'd like being able to help the development of GNOME. The last path that interests me is the path of the Smartphone Programmer. I have created some sample applications on Android and due to Java I found it a quite interesting experience. I can also see myself as an independent smartphone developer. These 3 paths seem equally interesting at the moment due to the shallowness of my experience, I guess. I know that I should spend time with all of them and then choose the right one for me but I'd like to know what are the pros and cons in terms of learning curve, fun, job finding and of course financial rewards with each of these paths. I have fair or basic understanding of the languages/technologies I described earlier and this question will help me choose where to focus, at least for now.

• Why is the MaskBit maxed out

  - by CStreel

  Hi there for some reason the maskbit of my b2FixtureDef is being maxxed out and im not sure why Here is the declaration of the items that are used in the game enum PhysicBits { PB_NONE = 0x0000, PB_PLAYER = 0x0001, PB_PLATFORM = 0x0002 }; Basically what i want is the player to run along a surface is not slow down (i set platform & player friction to 0.0f) I then setup my Contact Listener to print out the connections (currently only have 1 platform and 1 player) Player Fixture Def b2FixtureDef fixtureDef; fixtureDef.shape = &groundBox; fixtureDef.density = 1.0f; fixtureDef.friction = 0.0f; fixtureDef.filter.categoryBits = PB_PLAYER; fixtureDef.filter.maskBits = PB_PLATFORM; Platform Fixture Def b2FixtureDef fixtureDef; fixtureDef.shape = &groundBox; fixtureDef.density = 1.0f; fixtureDef.friction = 0.0f; fixtureDef.filter.categoryBits = PB_PLATFORM; fixtureDef.filter.maskBits = PB_PLAYER; Now correct me if im wrong but these are saying the following: Player Collides with Platform Platform Collides with Player Here is the printout of the fixtures colliding with each other ******** <-- Indicates new Contact Platform ContactA: 2 MaskA: 1 ------ Player ContactB: 1 MaskB: 2 ******** <-- Indicates new Contact Platform ContactA: 2 MaskA: 1 ------ Player ContactB: 1 MaskB: 65535 ******** <-- Indicates new Contact Platform ContactA: 1 MaskA: 65535 ------ Player ContactB: 1 MaskB: 65535 Here is where i am confused. On the second & third contact the player maskBit is set to 65535 when it should be 2 and there are 3 contacts when i am sure at most there should only be 2. I've been trying to figure this out for hours and i can't understand why it is doing this. I would be very grateful is someone could shine some light on this for me UPDATE: **I printed out the class of the contacting objects. For some reason it seems to do the following: First Contact: Correct Result. Second Contact: Player b2Fixture Obtains a new maskBit. Third Contact: Platform b2Fixture appears to be set to the same as the Player b2Fixture. It would seem I have a memory race condition i think**

• C Programming arrays, I dont understand how I would go about making this program, If anyone can just guide me through the basic outline please :) [on hold]

  - by Rashmi Kohli

  Problem The temperature of a car engine has been measured, from real-world experiments, as shown in the table and graph below: Time (min) Temperature (oC) 0 20 1 36 2 61 3 68 4 77 5 110 Use linear regression to find the engine’s temperature at 1.5 minutes, 4.3 minutes, and any other time specified by the user. Background In engineering, many times we measure several data points in an experiment, but then we need to predict a value that we have not measured which lies between two measured values, such as the problem statement above. If the relation between the measured parameters seems to be roughly linear, then we can use linear regression to find the relationship between those parameters. In the graph of the problem statement above, the relation seems to be roughly linear. Hence, we can apply linear regression to the above problem. Assuming y {y0, y1, …yn-1} has a linear relation with x {x0, x1, … xn-1}, we can say that: y = mx+b where m and b can be found with linear regression as follows: For the problem in this lab, using linear regression gives us the following line (in blue) compared to the measured curve (in red). As you can see, there is usually a difference between the measured values and the estimated (predicted) values. What linear regression does is to minimize those differences and still give us a straight line (blue). Other methods, such as non-linear regression, are also possible to achieve higher accuracy and better curve fitting. Requirements Your program should first print the table of the temperatures similar to the way it’s printed in the problem statement. It should then calculate the temperature at minute 1.5 and 4.3 and show the answers to the user. Next, it should prompt the user to enter a time in minutes (or -1 to quit), and after reading the user’s specified time it should give the value of the engine’s temperature at that time. It should then go back to the prompt. Hints •Use a one dimensional array to store the temperature values given in the problem statement. •Use functions to separate tasks such as calculating m, calculating b, calculating the temperature at a given time, printing the prompt, etc. You can then give your algorithm as well as you pseudo code per function, as opposed to one large algorithm diagram or one large sequence of pseudo code.

• git workflow for separating commits

  - by gman

  Best practices with git (or any VCS for that matter) is supposed to be to have each commit do the smallest change possible. But, that doesn't match how I work at all. For example I recently I needed to add some code that checked if the version of a plugin to my system matched the versions the system supports. If not print a warning that the plugin probably requires a newer version of the system. While writing that code I decided I wanted the warnings to be colorized. I already had code that colorized error message so I edited that code. That code was in the startup module of one entry to the system. The plugin checking code was in another path that didn't use that entry point so I moved the colorization code into a separate module so both entry points could use it. On top of that, in order to test my plugin checking code works I need to go edit UI/UX code to make sure it tells the user "You need to upgrade". When all is said and done I've edited 10 files, changed dependencies, the 2 entry points are now both dependant on the colorization code, etc etc. Being lazy I'd probably just git add . && git commit -a the whole thing. Spending 10-15 minutes trying to manipulate all those changes into 3 to 6 smaller commits seems frustrating which brings up the question Are there workflows that work for you or that make this process easier? I don't think I can some how magically always modify stuff in the perfect order since I don't know that order until after I start modifying and seeing what comes up. I know I can git add --interactive etc but it seems, at least for me, kind of hard to know what I'm grabbing exactly the correct changes so that each commit is actually going to work. Also, since the changes are sitting in the current directory it doesn't seem like it would be easy to run tests on each commit to make sure it's going to work short of stashing all the changes. And then, if it were to stash and then run the tests, if I missed a few lines or accidentally added a few too many lines I have no idea how I'd easily recover from that. (as in either grab the missing lines from the stash and then put the rest back or take the few extra lines I shouldn't have grabbed and shove them into the stash for the next commit. Thoughts? Suggestions? PS: I hope this is an appropriate question. The help says development methodologies and processes
