  • android shut-down errors / thread problems

    - by iQue
    Im starting to deal with some stuff in my game that I thought were "minor problems" and one of these are that I get an error every time I shut down my game that looks like this: 09-05 21:40:58.320: E/AndroidRuntime(30401): FATAL EXCEPTION: Thread-4898 09-05 21:40:58.320: E/AndroidRuntime(30401): java.lang.NullPointerException 09-05 21:40:58.320: E/AndroidRuntime(30401): at nielsen.happy.shooter.MainGamePanel.render(MainGamePanel.java:94) 09-05 21:40:58.320: E/AndroidRuntime(30401): at nielsen.happy.shooter.MainThread.run(MainThread.java:101) on these lines is my GameViews rendering-method and the line in my Thread that calls my GameViews rendering-method. Im guessing Something in my surfaceDestroyed(SurfaceHolder holder) is wrong, or maybe Im not ending the tread in the right place. My surfaceDestroyed-method: public void surfaceDestroyed(SurfaceHolder holder) { Log.d(TAG, "Surface is being destroyed"); boolean retry = true; ((MainThread)thread).setRunning(false); while (retry) { try { ((MainThread)thread).join(); retry = false; } catch (InterruptedException e) { } } Log.d(TAG, "Thread was shut down cleanly"); } Also, In my activity for this View my onPaus, onDestoy and onStop are empty, do I maybe need to add something there? The crash occurs when I press my home-button on the phone, or any other button that makes the game stop. But as I understand it the onPaus is called when you press the Home-button.. This is really new territory for me so Im sorry if im missing something obvious or something really big. adding my surfaceCreated method asweel since that is where I start this thread: public void surfaceCreated(SurfaceHolder holder) { controls = new GameControls(this); setOnTouchListener(controls); timer1.schedule(new Task(this), 0, delay1); thread.setRunning(true); thread.start(); } and aslong as this is running, my game is rendering and updating.

  • Autoresize UIScrollView

    - by Sebastian
    I made a UIViewController, which programatically generates a UIScrollView. Everything's fine, but when I rotate the Device, the UIScollView should resize so it takes the complete width of my View. Is there a way to do that without rebuilding the complete UIScrollView ? Thx a lot ! Sebastian This is called in my viewDidLoad: -(void)buildmyScroller { myScroller = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 800, 768, 100)]; //...adding some subviews to myScroller thumbScroller.contentSize = CGSizeMake(3000, 100); [[self view] addSubview:myScroller]; } Then I tried to resize myScroller with this: -(void)changemyScroller { UIInterfaceOrientation interfaceOrientation = self.interfaceOrientation; if (interfaceOrientation == UIInterfaceOrientationPortrait) { [thumbScroller setFrame:CGRectMake(0, 805, 768, 150)]; } else if (interfaceOrientation == UIInterfaceOrientationPortraitUpsideDown){ thumbScroller.frame = CGRectMake(0, 805, 768, 150); } else if (interfaceOrientation == UIInterfaceOrientationLandscapeLeft){ thumbScroller.frame = CGRectMake(0, 549, 1024, 150); } else if (interfaceOrientation == UIInterfaceOrientationLandscapeRight){ thumbScroller.frame = CGRectMake(0, 549, 1024, 150); } } And called the method in didAnimateFirstHalf... cause I'm not shure where else to call it. Thx a lot again !!

  • problem with joomla, php and json

    - by sebastian
    hi, i have a problem with a joomla component. i'm, unsing php and json for some dynamic drop down boxes. here is the code:` jQuery( function () { //jQuery.ajaxSetup({error : function (a,b) {console.dir(a); console.dir(b);}}); jQuery("#util, #loc").change( function() { var locatie = jQuery("#loc").val(); var utilitate = jQuery("#util").val(); if ( (locatie!= '---') && (utilitate!='---') ) jQuery.getJSON( "index.php?option=com_calculator&opt=json_contor&format=raw", { locatie: locatie, utilitate: utilitate }, function (data) { var html = ""; if ( data.success == 'ok' ) for (var i in data.val) html += "<option name=den_contor value ='"+ i+"' >" + data.val[i]+ " </option>"; jQuery("#den_contor").html( html ) } ) }) }); the query works, but only on one PC. we have exactly the same xampp server, exactly the same files. on one pc it works, and on a online server and on my pc it doesn't. EDIT: i have three drop down boxes, the first is populated directly from the database, the second has 4 predefined values. and the third is populated depending on combination of the first two. i have a test site online. http://contor.redxart.com must be logged in to use Calculator in the menu. you can make an new account :) "Adaugare Index" is the part that isn't working any ideas? thanks, sebastian

  • Realtek Semiconductor Co., Ltd. RTL8101E/RTL8102E

    - by Sebastian Bugiu
    I had Ubuntu 11.10 and in the last few weeks I experienced an obscure problem: after I had the computer running for a few days I could no longer connect to google.com or anything related to google. All sites worked with all browsers (Firefox, chrome, opera) except google. It remained in the connecting phase for a few minutes and either timed out or finally connected with this huge delay. Even if I entered other sites such as this one, if it had anything to do with google such adsense or gstatic or whatever with g in it, that site took a long time to load waiting in connecting to gstatic.com . Anything google related took minutes to work, but everything else worked instantly! I tried rebooting or using other machine(with windows on it) and this worked, so it's not network related. But after a few days it started not working again... So I upgraded to the Precise Pangolin hoping this behavior would go away. It didn't! After a few days I get the same behavior as in 11.10. What am I supposed to do? Reboot every other day? I didn't have this problem with neither 10.10 or 11.04. I found the Realtek RTL8168/8111E issue with the r8169 driver but this is not exactly the same card so probably trying r8168 won't help. Ethernet controller: Realtek Semiconductor Co., Ltd.

  • Alternatives to Firefox 3.5/POW on ubuntu natty to use SSJS

    - by Juan Sebastian Totero
    I have to install FFX 3.5 on my 11.04 machine. It's needed because I'm helping a friend of mine in a project involving Server-Side Javascript, and he is using POW webserver, actually avaliable for Linux only as a Firefox AddOn. (I know it's a dumb thing) The addon is compatible only with FFX 3.5 and older, but I cant' find any official package of Firefox 3.5 for linux. So the questions are two: Where can i find a package of Firefox 3.5 for linux? Is there any alternative SSJS webserver out there? IT's main use will be displaying ssjs files in the browser (possibly on-the-fly, that means I have not to create a webserver in SSJS, like in the case of nodejs)

  • Scientific evidence that supports using long variable names instead of abbreviations?

    - by Sebastian Dietz
    Is there any scientific evidence that the human brain can read and understand fully written variable names better/faster than abbreviated ones? Like PersistenceManager persistenceManager; in contrast to PersistenceManager pm; I have the impression that I get a better grasp of code that does not use abbreviations, even if the abbreviations would have been commonly used throughout the codebase. Can this individual feeling be backed up by any studies?

  • Ubuntu sudo not working

    - by Ron Sebastian
    I wanted to move a file to a /usr/python2.7/ but i was unable to do so, so i changed the permissions of /usr to myuser: sudo chown -R ***** /usr it worked but i realised it was a blunder when sudo stopped working after that. It says: sudo: effective uid is not 0, is sudo installed setuid root? I have seen this post where the accepted solution was to use the policykit: pkexec chown root:root /usr/bin/sudo pkexec chmod 4755 /usr/bin/sudo however, even the policykit is saying that: pkexec must be setuid root please help, i've learned a lesson and will never change permissions for /usr again. Please help me this time!

  • Music Manager thst can properly synch song ratings with Android

    - by Sebastian
    I'm moving from Windows 7 to Ubuntu, and so far the experience has been a really good one :) However, there is something that I've used to do with Windows 7 that I can't find how to do in Ubuntu: From my Windows music manager programs (either MediaMonkey or Windows Media Player) I could set song ratings in a way that the ratings set from either program could be also read from the other one. Additionally, song ratings were visible and updated in my iPod Touch when I synch'ed my music (either manually or using iTunes). To sum up, it seems that MediaMonkey, WMP, and the iPod device use standard mp3 metadata tag for ratings. Now, using Ubuntu 12.04, and now with an Android device: Rhythmbox can't see the song rates, despite those ratings can be seen by MediaMonkey and MS Music Player when I boot with Win7. Is this an issue I can fix with some setting? Is there any program I can use to accomplish this? What do you recommend to sync my music with Android (4.0, Galaxy s2), also keeping the song ratings information updated between Android and my PC? Thanks!!

  • Dell 3721 Wifi problem Ubuntu 13.04

    - by Sebastian
    I have a Dell 3721 which comes original with windows 8. I managed it to install ubuntu 12.10 on this laptop, even there was no out of the box drivers. With 12.10 I was forces to install this .deb package couple of times. After installing it, it was ok for some weeks before I have to install it again. Maybe some security updates destroy something which made in necessary to install it again... http://jas.gemnetworks.com/debian/pool/main/w/wireless-bcm43142/wireless-bcm43142-dkms_6.20.55.19-1_amd64.deb My problem is, that this package isnt working with ubuntu 13.04 anymore. So I cant use Wifi now. Also my display is almost dark, I cant change the brightness level with ubuntu 13.04. Hope you can give me some advice.

  • Issues while trying to install Xsane

    - by Sebastian
    :) I am sort of new in the world of Linux. I installed Zorin OS and I am very happy with it. My only problem is that I would like to be able to use my scanner. My Kodak printer works fine, but the scanner is not detected; therefore, I am trying to install Xsane. The issue remains, every time that I try to install it, and error message comes up saying; "Package dependencies cannot be resolved" What can I do? thanks!

  • How to rotate html5 canvas as page background?

    - by Sebastian P.R. Gingter
    Hi, I want to achieve the following: Image a white sheet of paper on a black desk. Then rotate the paper a little bit to the left (like, 25 degrees). Now you still have the black desk, and a rotated white box on it. In this rotated white box I want to place non-rotated normal html content like text, tables, div's etc. I already have a problem at the very first step: rotating a rectangle. This is my code so far: <html> <head> <script> function draw() { var canvas=document.getElementById("myCanvas"); var c=canvas.getContext("2d"); c.fillStyle = '#00'; c.fillRect(100, 100, 100, 100); c.rotate(20); c.fillStyle = '#ff0000'; c.fillRect(150, 150, 10, 10); } </script> </head> <body onload="draw()"> <canvas id="myCanvas" width="500" height="500"></canvas> </body> </html> With this, I see only a normal black box. Nothing else. I assume there should be a red, rotated box too, but there's nothing. What is the best approach to reach this and to have it as a (scaling) background for my web page?

  • Managing arbitrary user permissions under PureFTPd

    - by Sebastián Grignoli
    I need to provide an FTP service that needs to be web-managed in the simplest way possible. My customer wants to create folders and users, and give them read only or read/write access arbitrarily. For example: The folder 'Documents' should be read only for several users, writable for internal users, and invisible for the rest. The folder 'Pictures' should be read only for journalists, writable for associates, and invisible for the rest. The folder 'Media' should be read only, writable or invisible for arbitrary users specified on the admin. There could be a large number of users and folders. I can't find a good way to accomplish that. I thought that I could give each user a home folder and put symlinks for the folders he has read access to, and make the user part of the folder's group when he has write access too, but now I think that this wouldn't work, because with PureFTPd (or ProFTPd) I can only specify the virtual user's mapping to a system user, and only one GUID for each virtual user. My approach requires that I could specify several GUIDs for each user (one by each folder he has write access to). I need to start programming this admin and I still don't know wich approach would work, if any. ¿Any ideas?

  • Flashback Database

    - by Sebastian Solbach (DBA Community)
    Flashback Database bezeichnet die Funktionalität der Oracle Datenbank, die Datenbank zeitlich auf einen bestimmten Punkt, respektive eine bestimmte System Change Number (SCN) zurücksetzen zu können - vergleichbar mit einem Rückspulknopf eines Kassettenrekorders oder der Rücksetztaste eines CD-Players. Mag dieses Vorgehen bei Produktivsystemen eher selten Einsatz finden, da beim Rücksetzten alle Daten nach dem zurückgesetzten Zeitpunkt verloren wären (es sei denn man würde dieser vorher exportieren), gibt es gerade für Test- oder Standby Systeme viele Einsatzmöglichkeiten: Rücksetzten des Systems bei fehlgeschlagenen Applikations-Upgrade Alternatives Point in Time Recovery (PITR) mit anschließendem Roll Forward (besonders geeignet bei Standby Systemen) Testdatenbank mit definiertem, reproduzierbaren Ausgangspunkt (z.B. für Real Application Testing) Datenbank Upgrade Test Einige bestehende Datenbank Funktionalitäten verwenden Flashback Database implizit: Snapshot Standby Reinstanziierung der Standby (z.B. bei Fast Start Failover) Obwohl diese Funktionalität gerade für Standby Systeme und Testsysteme bestens geeignet ist, gibt es eine gewisse Zurückhaltung Flashback Database einzusetzen. Eine Ursache ist oft die Angst vor zusätzlicher Last, die das Schreiben der Flashback Logs erzeugt, sowie der zusätzlich benötigte Plattenplatz. Dabei ist die Last im Normalfall relativ gering (ca. 5%) und auch der zusätzlich benötigte Platz für die Flashback Logs lässt sich relativ genau bestimmen. Ebenfalls wird häufig nicht beachtet, dass es auch ohne das explizite Einschalten der Flashback Logs möglich ist, einen garantieren Rücksetzpunkt (Guaranteed Restore Point kurz GRP) festzulegen, und die Datenbank dann auf diesen Restore Point zurückzusetzen. Das Setzen eines garantierten Rücksetzpunktes funktioniert in 11gR2 im laufenden Betrieb. Wie dies genau funktioniert, welche Unterschiede es zum generellen Einschalten von Flashback Logs gibt, wie man Flashback Database monitoren kann und was es sonst noch zu berücksichtigen gibt, damit beschäftigt sich dieser Tipp.

  • Is it safe StringToHash() to use in Unity?

    - by Sebastian Krysmanski
    I'm currently browsing through the Unity tutorials and saw that they're recommending to use Animator.StringToHash("some string") to created unique ids for animation properties (see here). Since I'm a programmer, to me the word "hash" doesn't represents something unique. Like the Java documentation for hashValue() states: It is not required that if two objects are unequal [...], then calling the hashCode method on each of the two objects must produce distinct integer results. So, according to this (and my definition of "hash"), two strings may have the same hash value. (You can also argue that there are an infinite number of possible strings but only 2^32 possible int values.) So, is there a possibility that StringToHash() will give me an id that actually belongs to another property (than the one I requested the hash for)?

  • Login screen theme and background lost

    - by Sebastian Potasiak
    I tried to change my LightDM background and theme in Ubuntu 12.04 LTS beta 2, changing /usr/share/glib-2.0/schemas/com.canonical.unity-greeter.gschema.xml file (I don't even know if it would work, but I couldn't find any other way), and I failed and restored original file. Also, durning the same session I installed gnome-shell-extensions package, but it didn't work either. (I didn't remove it) Now my login screen looks a bit coarse, without theme and background. (It looks like MS Windows 95 a bit - square buttons and text fields) My question is, how to repair login screen (or how to customize it propely) and how to make gnome-shell-extensions work.

  • How to get faster iteration times in android development

    - by Sebastian Bugiu
    I'm creating a game on the android platform that uses the resources/raw folder for assets and scripts. The problem is that every time I change something I have to rebuild the application to test the new variant. Of course this is bad for iteration times. Any ideas about what I can do to avoid rebuilding every time I change something? This *.apk format is getting on my nerves now that I have to recreate it every time I change a word in my scripts. Or at least how to make eclipse auto-rebuild every time I change something in my resources folder so that I don't have to go to Project-Build every time?

  • How are "Json.org"-like specs graphs called and how can I generate them?

    - by Sebastián Grignoli
    In http://www.json.org Douglas Crockford shows the specs of the JSON format in two interesting ways: In the right side column he lists a text spec that looks like a YACC or LEX listing. In the main body of the homepage, he put several images that gives us a simple way to visually understand the valid sequences that composes a JSON string. Those images look like a description of the path that a finite state automaton would follow when parsing the JSON string. Wich are the names (if any) of that listing format and that kind of graphics? Is there any software that renders a source file containing the specification into that kind of images?

  • Algorithm to shoot at a target in a 3d game

    - by Sebastian Bugiu
    For those of you remembering Descent Freespace it had a nice feature to help you aim at the enemy when shooting non-homing missiles or lasers: it showed a crosshair in front of the ship you chased telling you where to shoot in order to hit the moving target. I tried using the answer from http://stackoverflow.com/questions/4107403/ai-algorithm-to-shoot-at-a-target-in-a-2d-game?lq=1 but it's for 2D so I tried adapting it. I first decomposed the calculation to solve the intersection point for XoZ plane and saved the x and z coordinates and then solving the intersection point for XoY plane and adding the y coordinate to a final xyz that I then transformed to clipspace and put a texture at those coordinates. But of course it doesn't work as it should or else I wouldn't have posted the question. From what I notice the after finding x in XoZ plane and the in XoY the x is not the same so something must be wrong. float a = ENG_Math.sqr(targetVelocity.x) + ENG_Math.sqr(targetVelocity.y) - ENG_Math.sqr(projectileSpeed); float b = 2.0f * (targetVelocity.x * targetPos.x + targetVelocity.y * targetPos.y); float c = ENG_Math.sqr(targetPos.x) + ENG_Math.sqr(targetPos.y); ENG_Math.solveQuadraticEquation(a, b, c, collisionTime); First time targetVelocity.y is actually targetVelocity.z (the same for targetPos) and the second time it's actually targetVelocity.y. The final position after XoZ is crossPosition.set(minTime * finalEntityVelocity.x + finalTargetPos4D.x, 0.0f, minTime * finalEntityVelocity.z + finalTargetPos4D.z); and after XoY crossPosition.y = minTime * finalEntityVelocity.y + finalTargetPos4D.y; Is my approach of separating into 2 planes and calculating any good? Or for 3D there is a whole different approach? sqr() is square not sqrt - avoiding a confusion.

    Egal ob Single Instanz oder für Real Applikation Cluster Datenbanken die Grid Infrastruktur findet man bei immer mehr Systemen im Einsatz. Das liegt sowohl an der vereinfachten Überwachungstätigkeiten für die Oracle Datenbank, Listener und ASM Instanz, als auch an einigen weiterführenden Features, wie der einfachen Service Verwaltung für Single Instanz, DataGuard und/oder RAC. Dabei kommen insbesondere den Cluster Ready Services (CRS), einem Bestandteil der Clusterware Komponente der Grid Infrastruktur, eine wichtige Bedeutung zu, da diese intern alle Ressourcen steuert. Ressourcen können hierbei natürlich nicht nur die Oracle Prozesse (Datenbank, Listener, Virtuelle IP Adressen etc.) sein, sondern auch eigene Applikationen, die unter die Überwachung der Grid Infrastruktur resp. Clusterware gestellt werden. Dies kann von simplen Neustartanforderungen im Single Server Betrieb bis zu klassischen Failover Szenarien in Clusterumgebungen reichen. Diesem Aspekt trägt auch die Tatsache Rechnung, dass es seit einiger Zeit generische Applikations-Agenten (Siebel, Tomcat, GoldenGate, Apache, ...) für die Clusterware gibt und eine abgespeckte GI Installation auf der Oracle eigenen Middleware Hardware (Exalogic) läuft, um die Prozesse zu überwachen. Diese Cluster Ready Services werden vom Befehl "crsctl" gesteuert. Deshalb lohnt es sich dieses Utility mal genauer anzuschauen, zumal es einige Feinheiten enthält, die nicht direkt aus der Dokumentation bzw. Hilfe des Tools ersichtlich sind.

  • Quick path jumping

    - by Sebastian P.
    I was just at a lecture, where I noticed the lecturer using a command (probably aliased) to jump to a specific folder. Example: ~/code$ j sciproj ~/projects/sciproj2011/$ This looked quite slick, so I started wondering: Is this a standard utility, and if so, what is the name? I have two theories as to how it works: It can both create, delete and jump to aliases directly from the command-line in the style of the example, without having to set up aliases in a configuration file or script or whatnot manually. It searches the home directory for a folder matching the name and jumps to it. The second option seems a bit slow, however, so the first would be preferred.

  • wierd keyboard problem

    - by Sebastian
    just installed ubuntu on a acer extensa 5620 laptop. The keyboard works fine except when i want to type things that require me to use ctrl+alt+(any key), i can't use ctrl+alt+(any key) in any program, I can open terminal with ctrl+alt+t tho... and ctrl+(any key) and alt+(any key) seems to work. Also I just installed the game Heroes of Newerth and neither alt or ctrl key seems to work in the game. Any answer would be appreciated!

  • Useful programming languages for hardware programming

    - by Sebastian Griotberg
    I am thinking to take the next semester a course called "Digital systems architecture", and I know that we need to program micro-controllers with several programming languages such as C, C++, verilog, and VHDL. I want to be prepared to take that course, but I need to know if I need to study deeper these languages. At this moment, I have taken one course in basic Java dealing with basic methods, data types, loop structures, vectors, matrices, and GUI programing. Must I study deeper Java and then go with C, and C++? Besides, I know basic verilog and VHDL.
