  • How can I decrease relevancy of Creative Commons footer text? (In Google Webmaster Tools)

    - by anonymous coward
    I know that I may just have to link the image to make this happen, but I figured it was worth asking, just in case there's some other semantic markup or tips I could use... I have a site that uses the textual Creative Commons blurb in the footer. The markup is like so: <div class="footer"> <!-- snip --> <!-- Creative Commons License --> <a rel="license" href="http://creativecommons.org/licenses/by-nc-sa/3.0/us/"><img alt="Creative Commons License" style="border-width:0" src="http://i.creativecommons.org/l/by-nc-sa/3.0/us/80x15.png" /></a><br />This work by <a xmlns:cc="http://creativecommons.org/ns#" href="http://www.xmemphisx.com/" property="cc:attributionName" rel="cc:attributionURL">xMEMPHISx.com</a> is licensed under a <a rel="license" href="http://creativecommons.org/licenses/by-nc-sa/3.0/us/">Creative Commons Attribution-Noncommercial-Share Alike 3.0 United States License</a>. <!-- /Creative Commons License --> </div> Within Google Webmaster Tools, the list of relevant keywords is heavily saturated with the text from that blurb. For instance, 50% of my top-ten most relevant keywords (including the site name): [site name] license [keyword] commons creative [keyword] alike [keyword] attribution [keyword] I have not done any extensive testing to find out rather or not this list even matters, and so far this doesn't impact performance in any way. The site is well designed for humans, and it is as findable as it needs to be at the moment. But, out of mostly curiosity: Do you have any tips for decreasing the relevancy of the text from the Creative Commons footer blurb?

  • Precision loss when transforming from cartesian to isometric

    - by Justin Skiles
    My goal is to display a tile map in isometric projection. This tile map has 25 tiles across and 25 tiles down. Each tile is 32x32. See below for how I'm accomplishing this. World Space World Space to Screen Space Rotation (45 degrees) Using a 2D rotation matrix, I use the following: double rotation = Math.PI / 4; double rotatedX = ((tileWorldX * Math.Cos(rotation)) - ((tileWorldY * Math.Sin(rotation))); double rotatedY = ((tileWorldX * Math.Sin(rotation)) + (tileWorldY * Math.Cos(rotation))); World Space to Screen Space Scale (Y-axis reduced by 50%) Here I simply scale down the Y value by a factor of 0.5. Problem And it works, kind of. There are some tiny 1px-2px gaps between some of the tiles when rendering. I think there's some precision loss somewhere, or I'm not understanding how to get these tiles to fit together perfectly. I'm not truncating or converting my values to non-decimal types until I absolutely have to (when I pass to the render method, which only takes integers). I'm not sure how to guarantee pixel perfect rendering precision when I'm rotating and scaling on a level of higher precision. Any advice? Do I need to supply for information?

  • Apache DVB http video Streaming bandwidth or priority problem

    - by igino manfre'
    I'm streaming few precompressed DVB videos from cloud. The streams are generated from VLC on "impossible" ports (such as 64085, 64086 etc) reverse proxed by Apache on port 80 and 8080. All the generated streams are listed in "http://95.110.164.61/indexv.html". From an ADSL connection with enough downlink bandwidth, recalling the stream generated by VLC (such as "http://95.110.164.61:64087/mpg2_6.4") it flows fluently. Recalling the same stream proxed by Apache ("http://95.110.164.61/mpg2_6.4") the stream stops and goes. The only situation in which the Apache proxed streams flow regularly is from a site connected through 64 Mbps warranted bandwith with RTT to the server less than 10 mseconds. Please note that streams below 2 Mbps are fluently proxed. The system is a single core xeon with windows 2008 R2 on 4 GB of RAM with 1 Gbps of network bandwidth. The drain of computational and bandwidth resources is negligeable, the RAM usage always lower than 50%. On the system I run many VLC streamers. Any of them drains a variable amount of RAM (from about 25 to 70 MB). On the contrary the couple of httpd.exe processes drain no more than 7 MB. Using Wireshark (on the server) I see that VLC directy send to the client much more packets than Apache, and the stream is framgmented on many frames. I'm not a programmer, a newby of Apache. Can anyone please address me to a specific portion of the Apache's huge documentation? Thank you. igino

  • Sudden drop in Total Indexed pages and increase in 'Not Selected' number.

    - by Pravin
    My blog is around 1 year old and have PR2. The average daily pageviews upto last 1 week were 1800. The total number of posts are 180. Though I have only 180 total posts, the total number of Indexed URL was increasing and it was as high as 510. But in the month of Sept2012, the total number of Indexed pages dropped from 510 to 214. The drop was sudden and it is now increasing very slowly. Also, the other main concern is huge increase in 'Not Selected' number. It is currently 814. I have never posted any post again and never copied any idea from any other blog. But I do use internal linking to some older post those are related to the new posts. The questions are:; Why there is sudden drop in the 'Total Indexed' pages. Why there was increase in total indexed pages to 500 even though the total posts were only 180. As the drop in 'Total Indexed' was in the month of sept2012, I was getting same organic traffic and it was steadily increasing till last week and then there was a 50 drop in the total pageviews. Why. Now, again the traffic is becoming to normal but still there is a problem. Is increase in the 'Not selected' number is a cause of drop in 'Total Indexed'? How to prevent or reduce the number of 'Not Selected' even though I do not have any duplicate post withing blog. Is the 'internal linking' to older post creating 'Not selected' problem? Should I edit my 'Robot.txt' to avoid crawling of labes that may be creating duplicate posts or something like that, if so, what is correct robot.txt. I have uploaded the screenshot of the graph of Webmaster Tools. Please take a look and give suggestions. Please help. Thank you in advance.

  • MonoGame not all letters being drawn with DrawString

    - by Lex Webb
    I'm currently making a dynamic user interface for my game and are setting up having text on my buttons. I'm having an odd issue where, when i use a specific piece of code to determine the text position, it will not render all of the text passed to DrawString. Even weirder, is if i insert another DrawString after this, drawing more text at a different place, different parts of the text will be drawn. The code for drawing my button with the text attached is: public override void Draw(SpriteBatch sb, GameTime gt) { sb.Draw(currentImage, GetRelativeRectangle(), Color.White); sb.DrawString(font, text, new Vector2(this.GetRelativeDrawOffset().X + this.Width / 2 - font.MeasureString(text).X / 2, this.GetRelativeDrawOffset().Y + this.Height / 2 - font.MeasureString(text).Y / 2), textColor); } The methods in the creation of the Vector2 simply get the draw position of the button. I'm then doing some calculation to center the text. This produces this when the text is set to 'Test': And when i enter this piece of code below the first DrawString: sb.DrawString(font, "test", new Vector2(500, 50), Color.Pink); I should mention that that grey square is being drawn in the same spritebatch, before the button and the text. Any ideas as to what could be causing this? I have a feeling it may be due to draw order, but i have no idea how to control that.

  • Producer-consumer pattern with consumer restrictions

    - by Dan
    I have a processing problem that I am thinking is a classic producer-consumer problem with the two added wrinkles that there may be a variable number of producers and there is the restriction that no more than one item per producer may be consumed at any one time. I will generally have 50-100 producers and as many consumers as CPU cores on the server. I want to maximize the throughput of the consumers while ensuring that there are never more than one work item in process from any single producer. This is more complicated than the classic producer-consumer problem which I think assumes a single producer and no restriction on which work items may be in progress at any one time. I think the problem of multiple producers is relatively easily solved by enqueuing all work items on a single work queue protected by a critical section. I think the restriction on simultaneously processing work items from any single producer is harder because I cannot think of any solution that does not require each consumer to notify some kind of work dispatcher that a particular work item has been completed so as to lift the restriction on work items from that producer. In other words, if Consumer2 has just completed WorkItem42 from Producer53, there needs to be some kind of callback or notification from Consumer2 to a work dispatcher to allow the work dispatcher to release the next work item from Producer53 to the next available consumer (whether Consumer2 or otherwise). Am I overlooking something simple here? Is there a known pattern for this problem? I would appreciate any pointers.

  • How do I fix a garbled screen on a Gateway LT3103u?

    - by paracaudex
    I've been having garbled screen problems on a Gateway LT3103u on Ubuntu for a while. I just did a fresh install of Ubuntu 11.10 and continue to have issues. I installed xubuntu-desktop in case the issues had to do with the sophisticated GNOME graphics. The problem is less bad, but it's still there. After a few minutes of using XFCE, the screen gets garbled. I assume this has something to do with the graphics card, but I don't know how to go about troubleshooting something like this. Where should I start? Update: Here is the description of the VGA card from lspci -vvv: 01:05.0 VGA compatible controller: ATI Technologies Inc RS690M [Radeon X1200 Series] (prog-if 00 [VGA controller]) Subsystem: Acer Incorporated [ALI] Device 028c Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx- Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast TAbort- SERR- [disabled] Capabilities: [50] Power Management version 2 Flags: PMEClk- DSI- D1+ D2+ AuxCurrent=0mA PME(D0-,D1-,D2-,D3hot-,D3cold-) Status: D0 NoSoftRst- PME-Enable- DSel=0 DScale=0 PME- Capabilities: [80] MSI: Enable- Count=1/1 Maskable- 64bit+ Address: 0000000000000000 Data: 0000 Kernel driver in use: radeon Kernel modules: radeon Update: Setting GRUB_CMDLINE_LINUX="nomodeset" in /etc/default/grub seems to have fixed it in both Ubuntu and xubuntu-desktop. I will test it for a day or so to see if the problems recur and then post more detail with some links to an explanation. Update 2: It is possible to use this fix for Nvidia card (GTX 260) when graphics is defective after 11.10 upgrade/install? First few restarts was graphic ok, then after few restarts begins suddenly be defective and it stay so. I must returned to 11.04 because this problem and I wait for 12.04. So I hope in this fix.

  • Recording slow web stream

  • Analytics - Where do my drop offs go?

    - by BadCash
    I have a website set up with Google Analytics (through the Wordpress plugin "Google Analytics for WordPress" by Joos de Valk). When I check out the visitors flow in Google Analytics, it shows something like this: (home) - 43% drop-offs /page-2/ - 10% drop-offs ... etc ... I have also set up events for external links. My main "goal" of the website is to drive traffic to my Android app on Google Play, so I have a couple of different links to that that are all set up as events. Everything seems to be working, my events show up when I go to Content - Events in Google Analytics. However, it seems to me that some percentage of the users that are reported as "drop-offs" in fact have clicked on one of the external links. But there's no info about the reason of those drop-offs in the Visitors flow-chart. I can of course check out each specific event category, event action and set "other" to Content/Page, which (I guess) shows the number of visitors who triggered a specific event on a specific page. It just seems like such a complicated way of going about this! So, is there a way to get a more detailed picture, including events, in the Visitors flow chart? Something like: (home) - 43% drop-offs Event Action: "Google Play"=50%, "Youtube"=10%, (not set)=40%

  • Ubuntu 12.04 does not suspend with proprietary driver for Radeon 6800

    - by Mike
    I'm running Ubuntu 12.04 x86_64 (though these issues have existed in previous releases too) and have a Radeon 6800 graphics card. I've run into issues with the open-source driver (the system would randomly hang when shutting down) so I switched to the proprietary driver (I compiled it myself using these instructions), but I am having new problems now. The main issue is that when I go into sleep mode, about 50-75% of the time, the screen goes black but the monitor does not actually shut off, and I can hear that the fans/hard drive are not suspending either. I can't get the computer to wake up (Ctrl+Alt+F1,2,3,etc. does not work), and I always end up force shutting down with the power button. I'd really appreciate help! Here is some information that might be helpful: $ fglrxinfo display: :0 screen: 0 OpenGL vendor string: Advanced Micro Devices, Inc.

  • Approach to retrieve files from server

    - by Aerus
    I'm in the process of making a Java application with a corresponding update application. At any given time the user may want to update the application and the updater will ask for a list of files of the latest release. Based on this list, the updater can determine which files need to be downloaded to complete the update. I now have 2 approaches to solve this, but i would like to know what approach will put the least stress on my application and server. I could send a list of files i want to download to my server and the server zips the files and simply returns this compressed file to the application. The updater sents a request for each seperate file to the server, which simply returns the file The application will be used mainly in Belgium and The Netherlands and connections/bandwidth tend to be pretty decent in here. The average size of a single file should be around 100Kb and at most 1Mb. I expect an update to have anywhere between 10 to 50 new files. I expect at most 100 persons/day to update the application, i.e. in the week when a new version is released. I hope this is enough information to sketch my problem and any advice is welcome. If there is another common way to tackle this, i'd be glad to hear it.

  • Looking for someone to point me in the right direction. I want to learn how to use hosted servers

    - by Leisure
    TL;DR: I want a Java program to run on a server, I want the server to forward a particular port from external to internal IP, I want store a few files on the server. Guides please. So I made a hack job Java program that acts as a server for my android application. It stores data in text files and HTML files, uploads them via FTP to my webhost, and manages socket connections (using port forwarding) with any phones connected. Right now I'm running it on NetBeans on my home computer. I know that it will probably slow down or crash once about 50 phones are connected at once. Is there any way I can run this program on a server with a high bandwidth? Can someone please find me a guide for that? I'm noob and don't know where to start looking. I seriously don't know anything about renting or using servers - I need a nice guide, and recommendations. My requirements for the server: Can handle about 2k socket connections at once Can run my Java code and store my txt files Can give me a port and an IP address so TCP/IP clients can be connected My budget: $50 CAD per month. Please someone set my ship sailing in the right direction, I really don't know where to look for resources.

  • Is this an acceptable approach to undo/redo in Python?

    - by Codemonkey
    I'm making an application (wxPython) to process some data from Excel documents. I want the user to be able to undo and redo actions, even gigantic actions like processing the contents of 10 000 cells simultaneously. I Googled the topic, and all the solutions I could find involves a lot of black magic or is overly complicated. Here is how I imagine my simple undo/redo scheme. I write two classes - one called ActionStack and an abstract one called Action. Every "undoable" operation must be a subclass of Action and define the methods do and undo. The Action subclass is passed the instance of the "document", or data model, and is responsible for committing the operation and remembering how to undo the change. Now, every document is associated with an instance of the ActionStack. The ActionStack maintains a stack of actions (surprise!). Every time actions are undone and new actions are performed, all undone actions are removed for ever. The ActionStack will also automatically remove the oldest Action when the stack reaches the configurable maximum amount. I imagine the workflow would produce code looking something like this: class TableDocument(object): def __init__(self, table): self.table = table self.action_stack = ActionStack(history_limit=50) # ... def delete_cells(self, cells): self.action_stack.push( DeleteAction(self, cells) ) def add_column(self, index, name=''): self.action_stack.push( AddColumnAction(self, index, name) ) # ... def undo(self, count=1): self.action_stack.undo(count) def redo(self, count=1): self.action_stack.redo(count) Given that none of the methods I've found are this simple, I thought I'd get the experts' opinion before I go ahead with this plan. More specifically, what I'm wondering about is - are there any glaring holes in this plan that I'm not seeing?

  • Change collision action

    - by PatrickR
    I have a collision detection and its working fine, the problem is, that whenever my "bird" is hitting a "cloud", the cloud dissapers and i get some points. The same happens for the "sol" which it should, but not with the clouds. How can this be changed ? ive tryed a lot, but can seem to figger it out. Collision Code - (void)update:(ccTime)dt { bird.position = ccpAdd(bird.position, skyVelocity); NSMutableArray *projectilesToDelete = [[NSMutableArray alloc] init]; for (CCSprite *bird in _projectiles) { bird.anchorPoint = ccp(0, 0); CGRect absoluteBox = CGRectMake(bird.position.x, bird.position.y, [bird boundingBox].size.width, [bird boundingBox].size.height); NSMutableArray *targetsToDelete = [[NSMutableArray alloc] init]; for (CCSprite *cloudSprite in _targets) { cloudSprite.anchorPoint = ccp(0, 0); CGRect absoluteBox = CGRectMake(cloudSprite.position.x, cloudSprite.position.y, [cloudSprite boundingBox].size.width, [cloudSprite boundingBox].size.height); if (CGRectIntersectsRect([bird boundingBox], [cloudSprite boundingBox])) { [targetsToDelete addObject:cloudSprite]; } } for (CCSprite *solSprite in _targets) { solSprite.anchorPoint = ccp(0, 0); CGRect absoluteBox = CGRectMake(solSprite.position.x, solSprite.position.y, [solSprite boundingBox].size.width, [solSprite boundingBox].size.height); if (CGRectIntersectsRect([bird boundingBox], [solSprite boundingBox])) { [targetsToDelete addObject:solSprite]; score += 50/2; [scoreLabel setString:[NSString stringWithFormat:@"%d", score]]; } } // NÅR SKYEN BLIVER RAMT AF FUGLEN for (CCSprite *cloudSprite in targetsToDelete) { //[_targets removeObject:cloudSprite]; //[self removeChild:cloudSprite cleanup:YES]; } // NÅR SOLEN BLIVER RAMT AF FUGLEN for (CCSprite *solSprite in targetsToDelete) { [_targets removeObject:solSprite]; [self removeChild:solSprite cleanup:YES]; } if (targetsToDelete.count > 0) { [projectilesToDelete addObject:bird]; } [targetsToDelete release]; } // NÅR FUGLEN BLIVER RAMT AF ALT ANDET for (CCSprite *bird in projectilesToDelete) { //[_projectiles removeObject:bird]; //[self removeChild:bird cleanup:YES]; } [projectilesToDelete release]; }

  • Ubuntu 12.04 Faster boot, Hibernate & other questions

    - by Samarth Shukla
    I've recently started exploring Ubuntu (my 1st distro). I fresh installed precise without a swap (4GB ram). The only issues are, slow boot (regardless of the swap) and instability after a few days of installation. The runtime performance is immaculate otherwise. Even though not needed, I still set swappiness = 10. I've tried the quiet splash profile to GRUB; already have preload installed. But it still is pretty slow. I am not too confident on recompiling the kernel yet. But you could please advice me on that too. I've also added the following to fstab: #Move /tmp to RAM: tmpfs /tmp tmpfs defaults,noexec,nosuid 0 0 (Also if you could please tell me the exact implication/scope of this tweak on physical ram & the swap.) But nothing has happened really. So what alternatives are there to make it boot faster? Also, right after fresh install, though no swap partition, the system still showed /dev/zram0 of arond 2GB which was never used (probably because of the above fstab edit). Finally, I experimented with Hibernate a little, but many claim that it doesn't work on 12.04. (Not to mention, I made a swap file of 4GB for it). What I did was: sudo gedit /var/lib/polkit-1/localauthority/50-local.d/hibernate.pkla Then I added the following lines, saved the file, and closed the text editor: [Re-enable Hibernate] Identity=unix-user:* Action=org.freedesktop.upower.hibernate ResultActive=yes I also edited the upower policy for hibernate: gksudo gedit /usr/share/polkit-1/actions/org.freedesktop.upower.policy I added these lines: < allow_inactive >no< /allow_inactive > < allow_active >yes< /allow_active > But it did not work. So is there an alternate method perhaps that can make it work on 12.04?

  • the correct way to deal with gtk_events_pending and gtk_main_iteration

    - by abd alsalam
    I have program that send files and i want to make a progress bar for it, but that progress bar just updated after the transferring complete,so i putted a gtk_events_pending() and gtk_main_iteration() functions in the sending loop to go back to the gtk main loop to update the progress bar but also it seems to not work here is a EDIT: the send function is in a separated thread snippet from my code float Percent = 0.0 ; float Interval = 0.0 ; the sending function gint SendTheFile ( ) { char FileBlockBuffer[512]; bzero(FileBlockBuffer, 512); int FileBlockSize ; FILE * FilePointer ; int filesize = 0 ; FilePointer = fopen(LocalFileName , "r"); struct stat st; stat(LocalFileName, &st); filesize = st.st_size; Interval = (512 / (float)filesize) ; while((FileBlockSize = fread(FileBlockBuffer,sizeof(char),512,FilePointer))>0) { send(SocketDiscriptor , FileBlockBuffer , FileBlockSize,0); bzero(FileBlockBuffer, 512); Percent = Percent + Interval ; if (Percent > 1.0)Percent = 0.0; while(gtk_events_pending() ) { gtk_main_iteration(); } } update progress bar function gint UpdateProgressBar(gpointer data) { gtk_progress_bar_set_fraction(GTK_PROGRESS_BAR(data),Percent); } updating progress bar in the main function g_timeout_add(50,(GSourceFunc)UpdateProgressBar,SendFileProgressBar);

  • Compute the AES-encryption key given the plaintext and its ciphertext?

    - by Null Pointers etc.
    I'm tasked with creating database tables in Oracle which contain encrypted strings (i.e., the columns are RAW). The strings are encrypted by the application (using AES, 128-bit key) and stored in Oracle, then later retrieved from Oracle and decrypted (i.e., Oracle itself never sees the unencrypted strings). I've come across this one column that will be one of two strings. I'm worried that someone will notice and presumably figure out what those two values to figure out the AES key. For example, if someone sees that the column is either Ciphertext #1 or #2: Ciphertext #1: BF,4F,8B,FE, 60,D8,33,56, 1B,F2,35,72, 49,20,DE,C6. Ciphertext #2: BC,E8,54,BD, F4,B3,36,3B, DD,70,76,45, 29,28,50,07. and knows the corresponding Plaintexts: Plaintext #1 ("Detroit"): 44,00,65,00, 74,00,72,00, 6F,00,69,00, 74,00,00,00. Plaintext #2 ("Chicago"): 43,00,68,00, 69,00,63,00, 61,00,67,00, 6F,00,00,00. can he deduce that the encryption key is "Buffalo"? 42,00,75,00, 66,00,66,00, 61,00,6C,00, 6F,00,00,00. I'm thinking that there should be only one 128-bit key that could convert Plaintext #1 to Ciphertext #1. Does this mean I should go to a 192-bit or 256-bit key instead, or find some other solution? (As an aside, here are two other ciphertexts for the same plaintexts but with a different key.) Ciphertext #1 A ("Detroit"): E4,28,29,E3, 6E,C2,64,FA, A1,F4,F4,96, FC,18,4A,C5. Ciphertext #2 A ("Chicago"): EA,87,30,F0, AC,44,5D,ED, FD,EB,A8,79, 83,59,53,B7.

  • starting up with VPS or cloud hosting? [closed]

    - by FlyOn
    Possible Duplicate: How to find web hosting that meets my requirements? Summary: I want to start hosting my product. I'd like to register domains (at some point). I'm a linux beginner. Thinking about scalability and price, I'm thinking am I better off on a VPN to get started or would some form of cloud hosting be better (not being familiar with either). Full question: I'm creating a product where people can create their own 3D representations of whatever data / info they have, and (re)organise that data. The product is coming along beautifully on my local environment, but it's about time I start getting some form of hosting ready, and I could really use some advice where / how to get started: I'd like people to be able to move/register their own domains on my server. I could start without this just to demo the product, but it would be the very first on the todo list. I'd like to automatically copy some files / install databases etc for each domain. I probably want to see if I can let users manage their own subdomains at some points, but for now: I'd like start as simple as possible. I've always on a windows machine, so my linux experience is quite basic. I really don't mind getting into it, but I'm thinking it's better to get my product out first of all and see where to go from there. Although... I'd like things to be scalable. If I set up some reseller VPN now which only scales to 100 domains or so, which means I have to set up something else / move again when I pass that level, or which means that I'm in trouble if I suddenly get lots of new customers... hmm. Finally, I need to start cheap. I'm putting all I have into starting this company, and live on very little. So before I have any customers, 50 dollars a month is a fair bit and 100 dollars a month may be too much. If anyone has some tips to help get me started I'd be really grateful.

  • Is creating a separate pool for each individual image created from a png appropriate?

    - by Panzercrisis
    I'm still possibly a little green about object-pooling, and I want to make sure something like this is a sound design pattern before really embarking upon it. Take the following code (which uses the Starling framework in ActionScript 3): [Embed(source = "/../assets/images/game/misc/red_door.png")] private const RED_DOOR:Class; private const RED_DOOR_TEXTURE:Texture = Texture.fromBitmap(new RED_DOOR()); private const m_vRedDoorPool:Vector.<Image> = new Vector.<Image>(50, true); . . . public function produceRedDoor():Image { // get a Red Door image } public function retireRedDoor(pImage:Image):void { // retire a Red Door Image } Except that there are four colors: red, green, blue, and yellow. So now we have a separate pool for each color, a separate produce function for each color, and a separate retire function for each color. Additionally there are several items in the game that follow this 4-color pattern, so for each of them, we have four pools, four produce functions, and four retire functions. There are more colors involved in the images themselves than just their predominant one, so trying to throw all the doors, for instance, in a single pool, and then changing their color properties around isn't going to work. Also the nonexistence of the static keyword is due to its slowness in AS3. Is this the right way to do things?
