  • java 7 upgrade and hibernate annotation processor error

    - by Bill Turner
    I am getting the following warning, which seems to be triggering a subsequent warning and an error. I have been googling like mad, though have not found anything that makes it clear what it is I should do to resolve this. This issue occurs when I execute an Ant build. I am trying to migrate our project to Java 7. I have changed all the source='1.6' and target="1.6" to 1.7. I did find this related article: Forward compatible Java 6 annotation processor and SupportedSourceVersion It seems to indicate that I should build the Hibernate annotation processor jar myself, compiling it with with 1.7. It does not seem I should be required to do so. The latest version of the class in question (in hibernate-validator-annotation-processor-5.0.1.Final.jar) has been compiled with 1.6. Since the code in said class refers to SourceVersion.latestSupported(), and the 1.6 of that returns only RELEASE_6, there does not seem to be a generally available solution. Here is the warning: [javac] warning: Supported source version 'RELEASE_6' from annotation processor 'org.hibernate.validator.ap.ConstraintValidationProcessor' less than -source '1.7' And, here are the subsequent warnings/error. [javac] warning: No processor claimed any of these annotations: javax.persistence.PersistenceContext,javax.persistence.Column,org.codehaus.jackson.annotate.JsonIgnore,javax.persistence.Id,org.springframework.context.annotation.DependsOn,com.trgr.cobalt.infrastructure.datasource.Bucketed,org.codehaus.jackson.map.annotate.JsonDeserialize,javax.persistence.DiscriminatorColumn,com.trgr.cobalt.dataroom.authorization.secure.Secured,org.hibernate.annotations.GenericGenerator,javax.annotation.Resource,com.trgr.cobalt.infrastructure.spring.domain.DomainField,org.codehaus.jackson.annotate.JsonAutoDetect,javax.persistence.DiscriminatorValue,com.trgr.cobalt.dataroom.datasource.config.core.CoreTransactionMandatory,org.springframework.stereotype.Repository,javax.persistence.GeneratedValue,com.trgr.cobalt.dataroom.datasource.config.core.CoreTransactional,org.hibernate.annotations.Cascade,javax.persistence.Table,javax.persistence.Enumerated,org.hibernate.annotations.FilterDef,javax.persistence.OneToOne,com.trgr.cobalt.dataroom.datasource.config.core.CoreEntity,org.springframework.transaction.annotation.Transactional,com.trgr.cobalt.infrastructure.util.enums.EnumConversion,org.springframework.context.annotation.Configuration,com.trgr.cobalt.infrastructure.spring.domain.UpdatedFields,com.trgr.cobalt.infrastructure.spring.documentation.SampleValue,org.springframework.context.annotation.Bean,org.codehaus.jackson.annotate.JsonProperty,javax.persistence.Basic,org.codehaus.jackson.map.annotate.JsonSerialize,com.trgr.cobalt.infrastructure.spring.validation.Required,com.trgr.cobalt.dataroom.datasource.config.core.CoreTransactionNever,org.springframework.context.annotation.Profile,com.trgr.cobalt.infrastructure.spring.stereotype.Persistor,javax.persistence.Transient,com.trgr.cobalt.infrastructure.spring.validation.NotNull,javax.validation.constraints.Size,javax.persistence.Entity,javax.persistence.PrimaryKeyJoinColumn,org.hibernate.annotations.BatchSize,org.springframework.stereotype.Service,org.springframework.beans.factory.annotation.Value,javax.persistence.Inheritance [javac] error: warnings found and -Werror specified TIA!

  • Is there a way to know what the Windows Disk Cleanup utility will delete?

    - by Cam Jackson
    When I run the Disk Cleanup utility that's built into Windows 8, it tells me that it can free up 53GB by deleting 'Temporary Files'. However, a CCleaner analysis on default settings only finds about 300MB worth of space to free up, so I'm wondering what Disk Cleanup has found that CCleaner does not. Note that this question appears to be similar to what I'm asking, but the accepted answer says that 'Temporary Files' refers to %TEMP%. I've already cleared out most of C:\Users\Cam\AppData\Local\Temp, and it now has only 230MB of stuff in it, even with system files showing. So where is this 53GB located? Is there a way to find out what it is? Edit: I should note that this is on a 110GB SSD, so it's almost half the drive. And in fact I'm only using 86GB, so if it's really going to clear out 53GB, that would be more than 60% of the stuff on my C drive. I'm starting to think that Disk Cleanup caches its analysis, and hasn't updated since I started cleaning up the drive earlier today. Although when I run it it says that it's 'Calculating' how much space can be saved, and it takes about 5-10 seconds to do so. Hmmm... Edit2: Here is what my hard drive looks like, according to SpaceMonger (Right click-Open image in new tab, so you can see it properly): You can see why I was starting to think that the 53GB figure is actually wrong. Even if 'Temporary Files' includes my hiberfil and everything in WinSxS (about 13GB total), that would be 26GB, which is only halfway there. Hard to see where there's 53GB of stuff to delete.

  • Multiple enemy array in LibGDX

    - by johnny-b
    I am trying to make a multiple enemy array, where every 30 secods a new bullet comes from a random point. And if the bullet is clicked it should disapear and a pop like an explosion should appear. And if the bullet hits the ball then the ball pops. so the bullet should change to a different sprite or texture. same with the ball pop. But all that happens is the bullet if touched pops and nothing else happens. And if modified then the bullet keeps flashing as the update is way too much. I have added COMMENTS in the code to explain more on the issues. below is the code. if more code is needed i will provide. Thank you public class GameRenderer { private GameWorld myWorld; private OrthographicCamera cam; private ShapeRenderer shapeRenderer; private SpriteBatch batcher; // Game Objects private Ball ball; private ScrollHandler scroller; private Background background; private Bullet bullet1; private BulletPop bPop; private Array<Bullet> bullets; // This is for the delay of the bullet coming one by one every 30 seconds. /** The time of the last shot fired, we set it to the current time in nano when the object is first created */ double lastShot = TimeUtils.nanoTime(); /** Convert 30 seconds into nano seconds, so 30,000 milli = 30 seconds */ double shotFreq = TimeUtils.millisToNanos(30000); // Game Assets private TextureRegion bg, bPop; private Animation bulletAnimation, ballAnimation; private Animation ballPopAnimation; public GameRenderer(GameWorld world) { myWorld = world; cam = new OrthographicCamera(); cam.setToOrtho(true, 480, 320); batcher = new SpriteBatch(); // Attach batcher to camera batcher.setProjectionMatrix(cam.combined); shapeRenderer = new ShapeRenderer(); shapeRenderer.setProjectionMatrix(cam.combined); // This is suppose to produce 10 bullets at random places on the background. bullets = new Array<Bullet>(); Bullet bullet = null; float bulletX = 00.0f; float bulletY = 00.0f; for (int i = 0; i < 10; i++) { bulletX = MathUtils.random(-10, 10); bulletY = MathUtils.random(-10, 10); bullet = new Bullet(bulletX, bulletY); AssetLoader.bullet1.flip(true, false); AssetLoader.bullet2.flip(true, false); bullets.add(bullet); } // Call helper methods to initialize instance variables initGameObjects(); initAssets(); } private void initGameObjects() { ball = GameWorld.getBall(); bullet1 = myWorld.getBullet1(); bPop = myWorld.getBulletPop(); scroller = myWorld.getScroller(); } private void initAssets() { bg = AssetLoader.bg; ballAnimation = AssetLoader.ballAnimation; bullet1Animation = AssetLoader.bullet1Animation; ballPopAnimation = AssetLoader.ballPopAnimation; } // This is to take the bullet away when clicked or touched. public void onClick() { for (int i = 0; i < bullets.size; i++) { if (bullets.get(i).getBounds().contains(0, 0)) bullets.removeIndex(i); } } private void drawBackground() { batcher.draw(bg1, background.getX(), background.getY(), background.getWidth(), backgroundMove.getHeight()); } public void render(float runTime) { Gdx.gl.glClearColor(0, 0, 0, 1); Gdx.gl.glClear(GL30.GL_COLOR_BUFFER_BIT); batcher.begin(); // Disable transparency // This is good for performance when drawing images that do not require // transparency. batcher.disableBlending(); drawBackground(); batcher.enableBlending(); // when the bullet hits the ball, it should be disposed or taken away and a ball pop sprite/texture should be put in its place if (bullet1.collides(ball)) { // draws the bPop texture but the bullet does not go just keeps going around, and the bPop texture goes. batcher.draw(AssetLoader.bPop, 195, 273); } batcher.draw(AssetLoader.ballAnimation.getKeyFrame(runTime), ball.getX(), ball.getY(), ball.getWidth(), ball.getHeight()); // this is where i am trying to make the bullets come one by one, and if removed via the onClick() then bPop animation // should play but does not??? if(TimeUtils.nanoTime() - lastShot > shotFreq){ // Create your stuff for (int i = 0; i < bullets.size; i++) { bullets.get(i); batcher.draw(AssetLoader.bullet1Animation.getKeyFrame(runTime), bullet1.getX(), bullet1.getY(), bullet1.getOriginX(), bullet1.getOriginY(), bullet1.getWidth(), bullet1.getHeight(), 1.0f, 1.0f, bullet1.getRotation()); if (bullets.removeValue(bullet1, false)) { batcher.draw(AssetLoader.ballPopAnimation.getKeyFrame(runTime), bPop1.getX(), bPop1.getY(), bPop1.getWidth(), bPop1.getHeight()); } } /* Very important to set the last shot to now, or it will mess up and go full auto */ lastShot = TimeUtils.nanoTime(); } // End SpriteBatch batcher.end(); } } Thank you

  • Webcam on Sony Vaio on Win 7 problem

    - by Norm
    Anyone know where I can get a Win 7 32Bit driver for my Web Cam (Vaio VGN-CR11H/B) ? I changed operating system from Chinese Vista to English Win 7 Update: Windows 7 will not detect the cam, but I just read the Sony Europe site and it gives me some ideas to try. I can dual boot this Sony laptop: with Chinese Vista, the camera works but IE8 does not work. I cannot read Chinese to fix the Internet access issue, but I can get the computer online and Skype works. When I boot with the new Win 7, IE 8 works great, but the cam doesn't work (mic and speakers work). Very perplexing problem.

  • Gesture Detector not firing

    - by Tyler
    So I'm trying to create a input class that implements a InputHandler & GestureListener in order to support both Android & Desktop. The problem is that not all the methods are being called properly. Here is the input class definition & a couple of the methods: public class InputHandler implements GestureListener, InputProcessor{ ... public InputHandler(OrthographicCamera camera, Map m, Player play, Vector2 maxPos) { ... @Override public boolean zoom(float originalDistance, float currentDistance) { //this.zoom = true; this.zoomRatio = originalDistance / currentDistance; cam.zoom = cam.zoom * zoomRatio; Gdx.app.log("GestureDetector", "Zoom - ratio: " + zoomRatio); return true; } @Override public boolean touchDown(int x, int y, int pointerNum, int button) { booleanConditions[TOUCH_EVENT] = true; this.inputButton = button; this.inputFingerNum = pointerNum; this.lastTouchEventLoc.set(x,y); this.currentCursorPos.set(x,y); if(pointerNum == 1) { //this.fingerOne = true; this.fOnePosition.set(x, y); } else if(pointerNum == 2) { //this.fingerTwo = true; this.fTwoPosition.set(x,y); } Gdx.app.log("GestureDetector", "touch down at " + x + ", " + y + ", pointer: " + pointerNum); return true; } The touchDown event always occurs but I can never trigger Zoom (or pan among others...). The following is where I register and create the input handler in the "Game Screen". public class GameScreen implements Screen { ... this.inputHandler = new InputHandler(this.cam, this.map, this.player, this.map.maxCamPos); Gdx.input.setInputProcessor(this.inputHandler); Anyone have any ideas why zoom, pan, etc... are not triggering? Thanks!

  • Android app hanging, sometimes until Force Close / Wait dialog appears

    - by fredley
    I'm making an app that records uncompressed (wav format) audio. I'm using this class to actually record the audio. Currently, my application records fine (I can play the file), however when I click the button to stop the recording, the app hangs for 10 seconds or so, with no log output or any signs of life. Finally it comes round, dumps a load of errors into the log, updates the UI etc. I'm using AsyncTasks to try and avoid this kind of thing but it's not working. Here's my code: //Called on clicks of the record button. rar is the instance of RehearsalAudioRecorder private OnClickListener RecordListener = new OnClickListener(){ @Override public void onClick(View v) { Log.d("Record","Click"); if (recording){ new stopRecordingTask().execute(rar,null,null); startStop.setText("Record"); statusBar.setText("Recording Finished, ready to Encode"); }else{ recording = true; new startRecordingTask().execute(rar,null,null); startStop.setText("Stop"); statusBar.setText("Recording Started"); } } }; private class startRecordingTask extends AsyncTask<RehearsalAudioRecorder,Void,Void>{ @Override protected Void doInBackground(RehearsalAudioRecorder... rs) { RehearsalAudioRecorder r = rs[0]; r.setOutputFile("/sdcard/rarOut.wav"); r.prepare(); r.start(); return null; } } private class stopRecordingTask extends AsyncTask<RehearsalAudioRecorder,Void,Void>{ @Override protected Void doInBackground(RehearsalAudioRecorder... rs) { RehearsalAudioRecorder r = rs[0]; r.stop(); r.reset(); return null; } } In Logcat, I always get output like this, which has me stumped. I have no idea what's causing it (I'm logging the RehearsalAudioRecorder class, and it's being started/stopped correctly by the button clicks. This output occurs after the log output for the button click and correct stop() method call) 12-19 11:59:11.172: ERROR/AudioRecord-JNI(22662): Unable to retrieve AudioRecord object, can't record 12-19 11:59:11.172: ERROR/uk.ac.cam.tfmw2.steg.RehearsalAudioRecorder(22662): Error occured in updateListener, recording is aborted 12-19 11:59:11.172: ERROR/uk.ac.cam.tfmw2.steg.RehearsalAudioRecorder(22662): stop() called on illegal state: STOPPED 12-19 11:59:11.172: ERROR/AudioRecord-JNI(22662): Unable to retrieve AudioRecord object, can't record 12-19 11:59:11.172: ERROR/uk.ac.cam.tfmw2.steg.RehearsalAudioRecorder(22662): Error occured in updateListener, recording is aborted 12-19 11:59:11.172: ERROR/uk.ac.cam.tfmw2.steg.RehearsalAudioRecorder(22662): stop() called on illegal state: ERROR 12-19 11:59:11.172: ERROR/AudioRecord-JNI(22662): Unable to retrieve AudioRecord object, can't record 12-19 11:59:11.172: ERROR/uk.ac.cam.tfmw2.steg.RehearsalAudioRecorder(22662): Error occured in updateListener, recording is aborted 12-19 11:59:11.172: ERROR/uk.ac.cam.tfmw2.steg.RehearsalAudioRecorder(22662): stop() called on illegal state: ERROR ... 10 or more times I've been fiddling with this all day and I'm not getting anywhere, any input would be greatly appreciated. Update I've replace the AsyncTasks with Threads, still doesn't work, the app completely hangs when I click record, despite the fact the Log indicates there's nothing going on in the main thread. Still completely stumped.

  • Ubuntu 13.04 running really slow and Hanging

    - by CAM
    Up till recently I have been running 13.04 on my laptop very happily. This morning however, I turned on my laptop to find it running really slow. Takes 5 min to load a program and even then the program freezes and I have had 3 system hangs this morning already. The Unity Desktop appears to run ok but programs do not. Things I have tried so far: Checking for Propitiatory graphics drivers - none shown available (I have bumblebee running already). Using the recovery boot options from Grub to repair broken packages. Recent changes - Updated computer, Installed some indicator applets which have worked fine for me before. System Specs: Asus U36s, Intel Core i5-2450M 2.5GHz, 4GB RAM, Nvidia Geforce 610M-1GB, Dual boot Win7 & Ubuntu 13.04 I'm a bit of a noob with Ubuntu but am happy enough running stuff in terminal if you will advise me on what to run. I'm just a bit stuck on what do to fix this without a reinstall. Thanks a lot for your help.

  • Where have the Direct3D 11 tutorials on MSDN have gone?

    - by Cam Jackson
    I've had this tutorial bookmarked for ages. I've just decided to give DX11 a real go, so I've gone through that tutorial, but I can't find where the next one in the series is! There are no links from that page to either the next in the series, or back up to the table of contents that lists all of the tutorials. These are just companion tutorials to the samples that come with the SDK, but I find them very helpful. Searching MSDN from google and the MSDN Bing search box has turned up nothing, it's like they've removed all links to these tutorials, but the pages are still there if you have the URLs. Unfortunately, MSDN URLs are akin to youtube URLs, so I can't just guess the URL of the next tutorial. Anyone have any idea what happened to these tutorials, or how I can find the others?

  • Take contentd from url and place in container on page

    Hi There, I would like to use jQuery to find the last page name / directory from the url and display it on the page in a <h3> container. For example: /_blog/PunkLogic_News/tag/videos/ I would like to display 'videos' in a specific <h3 class="urltag"> on the page. /_blog/PunkLogic_News/tag/Noosa_Biosphere/ I would like to display 'Noosa Biosphere' without the underscore. I suppose all special characters would need to be removed as well. Thanks in advance for your help. Jackson

  • FTP server deatails according to domain

    - by Phil Jackson
    Hello, What I am trying to accomplish is getting relative and absolute paths to files, images and folders that reside on a remote server. I have website address, and FTP details (these are required when signing up). What i need to know is whether the FTP details correspond correctly with the website. Firstly I used (this is all in PHP I forgot to add) : $conn_id = ftp_connect("ftp.".$WEBSITE); if($login_result = ftp_login ($conn_id, $ftpUser, $ftpPass)) which works. BUT what i dont know, and am not sure about at all, will ("ftp.".$WEBSITE) be sufficient for all "FTP servers"? Regards, Phil Jackson

  • libgdx draw issue and animation

    - by johnny-b
    it seems as though i cannot get the draw method to work??? it seems as though the bullet.draw(batcher) does not work and i cannot understand why as the bullet is a sprite. i have made a Sprite[] and added them as animation. could that be it? i tried batcher.draw(AssetLoader.bulletAnimation.getKeyFrame(runTime), bullet.getX(), bullet.getY(), bullet.getOriginX() / 2, bullet.getOriginY() / 2, bullet.getWidth(), bullet.getHeight(), 1, 1, bullet.getRotation()); but that dont work, the only way it draws is this batcher.draw(AssetLoader.bulletAnimation.getKeyFrame(runTime), bullet.getX(), bullet.getY()); below is the code. // this is in a Asset Class texture = new Texture(Gdx.files.internal("SpriteN1.png")); texture.setFilter(TextureFilter.Nearest, TextureFilter.Nearest); bullet1 = new Sprite(texture, 380, 350, 45, 20); bullet1.flip(false, true); bullet2 = new Sprite(texture, 425, 350, 45, 20); bullet2.flip(false, true); Sprite[] bullets = { bullet1, bullet2 }; bulletAnimation = new Animation(0.06f, bullets); bulletAnimation.setPlayMode(Animation.PlayMode.LOOP); // this is the GameRender class public class GameRender() { private Bullet bullet; private Ball ball; public GameRenderer(GameWorld world) { myWorld = world; cam = new OrthographicCamera(); cam.setToOrtho(true, 480, 320); batcher = new SpriteBatch(); // Attach batcher to camera batcher.setProjectionMatrix(cam.combined); shapeRenderer = new ShapeRenderer(); shapeRenderer.setProjectionMatrix(cam.combined); // Call helper methods to initialize instance variables initGameObjects(); initAssets(); } private void initGameObjects() { ball = GameWorld.getBall(); bullet = myWorld.getBullet(); scroller = myWorld.getScroller(); } private void initAssets() { ballAnimation = AssetLoader.ballAnimation; bulletAnimation = AssetLoader.bulletAnimation; } public void render(float runTime) { Gdx.gl.glClearColor(0, 0, 0, 1); Gdx.gl.glClear(GL30.GL_COLOR_BUFFER_BIT); batcher.begin(); // Disable transparency // This is good for performance when drawing images that do not require // transparency. batcher.disableBlending(); // The ball needs transparency, so we enable that again. batcher.enableBlending(); batcher.draw(AssetLoader.ballAnimation.getKeyFrame(runTime), ball.getX(), ball.getY(), ball.getWidth(), ball.getHeight()); batcher.draw(AssetLoader.bulletAnimation.getKeyFrame(runTime), bullet.getX(), bullet.getY()); // End SpriteBatch batcher.end(); } } // this is the gameworld class public class GameWorld { public static Ball ball; private Bullet bullet; private ScrollHandler scroller; public GameWorld() { ball = new Ball(480, 273, 32, 32); bullet = new Bullet(10, 10); scroller = new ScrollHandler(0); } public void update(float delta) { ball.update(delta); bullet.update(delta); scroller.update(delta); } public static Ball getBall() { return ball; } public ScrollHandler getScroller() { return scroller; } public Bullet getBullet() { return bullet; } } is there anyway so make the sprite work?

  • Synchronising Cut-and-Paste Activities in Ubuntu One

    - by Jackson Tan
    This was posted in the Ubuntu Forums but received no response, so I'm re-posting it here (with minor updates) in hopes that it will at least get some comments. Recently, I moved a large amount of contents (a few GBs) within the Ubuntu One folder (through cut-and-paste). Then I discovered how Ubuntu One does this is to remove them on the server side and upload all the files again in the new location. Obviously, this is undesirable because of the hefty uploading involved. Worse, since I have two computers synced to the same account, it is double the amount of traffic. Each computer took about one day to finish synchronising. Firstly, can anyone confirm that this is actually what's happening when we move folders? I'm using Ubuntu 10.04, by the way. Secondly, is there a way to cut-and-paste stuff within the Ubuntu One folder without uploading again?

  • Web Development Law/Ownership of Website

    - by Jackson Buddingh
    I'm a budding web developer, and I wondered if it was illegal to edit a website for a client to include a link that says 'encourage the owner of this site to pay their web developer' and follows up with a pre-made email encouraging the man to pay me. Here are the conditions: I've completed the work for the contract. I've asked to be paid, and tried to set up meetings with the owner. I've informed the owner of the site that my work will not continue unless I am paid. I should have been paid nearly a month ago (12/27) Any thoughts other than small claims? This is my first web-development job!

  • Flood fill algorithm for Game of Go

  • FloodFill Algorithm for Game of Go

    - by Jackson Borghi

  • Standard way of allowing general XML data

    - by Greg Jackson
    I'm writing a data gathering and reporting application that takes XML files as input, which will then be read, processed, and stored in a strongly-typed database. For example, an XML file for a "Job" might look like this: <Data type="Job"> <ID>12345</ID> <JobName>MyJob</JobName> <StartDate>04/07/2012 10:45:00 AM</StartDate> <Files> <File name="a.jpeg" path="images\" /> <File name="b.mp3" path="music\mp3\" /> </Files> </Data> I'd like to use a schema to have a standard format for these input files (depending on what type of data is being used, for example "Job", "User", "View"), but I'd also like to not fail validation if there is extra data provided. For example, perhaps a Job has additional properties such as "IsAutomated", "Requester", "EndDate", and so on. I don't particularly care about these extra properties. If they are included in the XML, I'll simply ignore them when I'm processing the XML file, and I'd like validation to do the same, without having to include in the schema every single possible property that a customer might provide me with. Is there a standard way of providing such a schema, or of allowing such a general XML file that can still be validated without resorting to something as naïve (and potentially difficult to deal with) as the below? <Data type="Job"> <Data name="ID">12345</Data> . . . <Data name="Files"> <Data name="File"> <Data name="Filename">a.jpeg</Data> <Data name="path">images</Data> . . . </Data> </Data>

  • Linux DD command partition -to- partition

    - by Ben Jackson
    I just used the DD command to copy the contents of one partition over to another partition on another drive, like this: dd if=/dev/sda2 of=/dev/sdb2 bs=4096 conv=noerror sda2 partition was 66GB and sdb2 was 250GB. I read that by doing this the extra space on the drive I am copying to will be wasted, is this true? I wasn't worried about loosing the extra space for the time being however, I just ran: sudo kill -USR1 (PID) to view the current status of DD and it has written over 66GB of data, will it continue to write data until it gets to 250GB? If so, is there a way to stop the process without corrupting it as waiting for it to write blank space seems like a waste of time.

  • How to handle growing QA reporting requirements?

    - by Phillip Jackson
    Some Background: Our company is growing very quickly - in 3 years we've tripled in size and there are no signs of stopping any time soon. Our marketing department has expanded and our IT requirements have as well. When I first arrived everything was managed in Dreamweaver and Excel spreadsheets and we've worked hard to implement bug tracking, version control, continuous integration, and multi-stage deployment. It's been a long hard road, and now we need to get more organized. The Problem at Hand: Management would like to track, per-developer, who is generating the most issues at the QA stage (post unit testing, regression, and post-production issues specifically). This becomes a fine balance because many issues can't be reported granularly (e.g. per-url or per-"page") but yet that's how Management would like reporting to be broken down. Further, severity has to be taken into account. We have drafted standards for each of these areas specific to our environment. Developers don't want to be nicked for 100+ instances of an issue if it was a problem with an include or inheritance... I had a suggestion to "score" bugs based on severity... but nobody likes that. We can't enter issues for every individual module affected by a global issue. [UPDATED] The Actual Questions: How do medium sized businesses and code shops handle bug tracking, reporting, and providing useful metrics to management? What kinds of KPIs are better metrics for employee performance? What is the most common way to provide per-developer reporting as far as time-to-close, reopens, etc.? Do large enterprises ignore the efforts of the individuals and rather focus on the team? Some other questions: Is this too granular of reporting? Is this considered 'blame culture'? If you were the developer working in this environment, what would you define as a measureable goal for this year to track your progress, with the reward of achieving the goal a bonus?

  • 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.
