• What kind of hosting do I need?

  - by Robert Smith

  I migrated this question from serverfault. Hopefully this is the appropriate place. I have been trying to answer this question but I haven't found an specific answer to my situation. As I want to pay for what I need, I thought I could get a good answer here. I have a custom made forum (rather than a built-in forum like the ones you can find in plugins, e.g. WP-Forum or phpBB type of software) in Django. I don't want to use Apache and modwsgi because it's usually very memory-hungry and I can't afford a big server. I prefer a combination of nginx and gunicorn which I think is very efficient (maybe you can also tell me what you think about that). I'm expecting to receive 10,000 to 20,000 visits each month with 15,000 to 30,000 page impressions. I have reviewed some cloud services like Amazon EC2 or Rackspace and other more traditional services (Linodo). This site won't use videos or big images and I certainly don't need a huge amount of bandwidth (200GB would be definitely too much). I need shell access so shared hosting is out of the question. What do I need to run a website like that without problems? What about RAM? 256MB would be enough (that's the amount of RAM offered by small instances in Amazon and Rackspace)? Do you know of any alternative to those I mentioned? If you need more information to provide a useful answer, please don't hesitate to ask. By the way, I was told that Linodo is not all that different to Amazon EC2 but this website is supposed to work 24/7, so I can't take advantage of Linodo's flexibility regarding creating and deleting instances. Thanks in advance.

• Creating a SQL Azure Database Should be Easier

  - by Ken Cox [MVP]

  Every time I try to create a database + tables + data for Windows Azure SQL I get errors.  One of them is 'Filegroup reference and partitioning scheme' is not supported in this version of SQL Server.' It’s partly due to my poor memory (since I’ve succeeded before) and partly due to the failure of tools that should be helping me. For example, when I want to create a script from an existing database on my local workstation, I use SQL Server Management Studio (currently v 11.0.2100.60).  I go to Tasks > Generate Scripts which brings up the nice Generate and Publish Scripts wizard. When I go into the Advanced button, under Script for Server Version, why don’t I see SQL Azure as an option by now? The tool should be sorting this out for me, right? Maybe this is available in SQL Server Data Tools? I haven’t got into that yet. Just merge the functionality with SSMS, please. Anyway, I pick an older version of SQL for the target and still need to tweak it for Azure. For example, I take out all the “[dbo].” stuff. Why is it put there by the wizard? I also have to get rid of "ON [PRIMARY]"  to deal with the error I noted at the top. Yes, there’s information on what a table needs to look like in SQL Azure but the tools should know this so I don’t have to mess with it.

• Photoshop alternative with same keyboard shorcuts

  - by user292254

  tldr; Is there a program with the same keyboard shortcuts and/or user interface as PS. I know the "photoshop alternative" question has been asked so many times, but I feel this variant is worth the time to ask. I am a web designer and have been using PS daily on a windows or mac machine for about 10 years, but I do most of my development in linux. The only thing that has been keeping me from the full switch to linux is PS. I have tried many alternatives, including GIMP, but I feel the barrier to entry is too high for one reason and one reason only, the keyboard shortcuts. Over the years I have become very adept and quick in the use of PS because of keyboard shortcuts and muscle memory. I realize that many shortcuts can be customized, but many actions are just too different from PS. So my question is what programs are out there that are the closest to PS in keyboard shortcuts and interface. I don't care if I have to do a bunch of customization to get it as close as possible, but I just can't take too much time to learn a completely new workflow. Of course I realize that any software will take time and effort, I just want to make that time/effort as minimal as possible. Thanks in advance for your responses. edit I should tell you the most important features and workflow I use on a daily basis are, Smart objects, linked documents, save for web and devises.

• how to install Ubuntu on a fresh hard drive

  - by Herman Wiegman

  I attempted to install Ubuntu from a USB stick to my Intel 4 3GHz computer with 80GB HDD. The installer was doing well, then it said something to the effect of "errors on the source USB, or the target HDD" The recommendation was to download the installer again. I suspected my HDD was going bad so I figured I would investigate. What I found was a partially formatted 80GB HDD. I repartitioned it via a different computer. Now a fresh copy of the Ubuntu USB installer is not able to move past the start-up screen (it freezes). I was able to purchase a new / clean HDD, but still the fresh copy of the installer still locks up after the initial opening screen (locks up after about 2 screens worth of installations steps). Does this sounds like a HDD NTHS issue or a CPU/hardware/memory issue? or should I move to a CD image file rather than my USB stick? Now my computer is stuck... no OS.. no way to go back to Windows (upgrade OS CD only). Any insight would be greatly appreciated. Stuck in Schenectady Herman Wiegman

• Ubuntu 11.10 not starting in Graphical mode?

  - by iammilind

  I am in deep trouble. I am using Ubuntu 11.10 in dual boot mode with XP. Originally my touch pad was not working, (sometimes). To fix that, I installed something. After reboot my Ubuntu is not booting up!! I have several software pkgs already installed in past several weeks so reinstall of OS is my last resort. Can someone help me to get it rebooted in graphical mode? I had followed the procedure mentioned in this thread as well. With that link, somehow I am able to restart in text mode. But no luck after that. I am not being able to go back on graphical mode. The important outputs of lspci are following: 00.00.0 Host bridge: Intel Corporation Mobile PM965/GM965/GL960 Memory Controller Hub (rev 0c) 00:02.0 VGA compatible controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (primary) (rev 0c) 00:02.0 Display controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (primary) (rev 0c) I am attaching few snapshots, for more details on hardware.

• Are these advanced/unfair interview questions regarding Java concurrency?

  - by sparc_spread

  Here are some questions I've recently asked interviewees who say they know Java concurrency: Explain the hazard of "memory visibility" - the way the JVM can reorder certain operations on variables that are unprotected by a monitor and not declared volatile, such that one thread may not see the changes made by another thread. Usually I ask this one by showing code where this hazard is present (e.g. the NoVisibility example in Listing 3.1 from "Java Concurrency in Practice" by Goetz et al) and asking what is wrong. Explain how volatile affects not just the actual variable declared volatile, but also any changes to variables made by a thread before it changes the volatile variable. Why might you use volatile instead of synchronized? Implement a condition variable with wait() and notifyAll(). Explain why you should use notifyAll(). Explain why the condition variable should be tested with a while loop. My question is - are these appropriate or too advanced to ask someone who says they know Java concurrency? And while we're at it, do you think that someone working in Java concurrency should be expected to have an above-average knowledge of Java garbage collection?

• Unsure about TRIM enabled on my SSD

  - by user84750

  I have a SSD OCZ Vertex4 installed on my laptop. I'm running Ubuntu 12.04 LTS. I have enable TRIM by adding "discard" to my fstab file. (also added option noatime). I rebooted my Ubuntu and followed These instructions here to test TRIM. The end results of my tempfile was all ffff's, when it should have read all zero's, which is telling me TRIM is not really working or enabled correctly. Did I miss something? Also, will it be a problem if only my /home directory is encrypted. AND if you ask why I have swap on my SSD, it's because I let Ubuntu set up my partition. When I have my SSD, I just wanted to install Ubuntu as fast as possible. =) I've done testing to see at which point it will start to use swap and it took a lot of applications open to finally use swap. I currently have 4 GB of memory. I might shrink this to like 512 MB or 1 GB the most. Here's some info about my file system setup. sudo hdparm -I /dev/sda1 | grep "TRIM supported" Data Set Management TRIM supported (limit 16 blocks) sudo fdisk -l /dev/sda Device Boot Start End Blocks Id System /dev/sda1 * 2048 242016255 121007104 83 Linux /dev/sda2 242018302 250068991 4025345 5 Extended /dev/sda5 242018304 250068991 4025344 82 Linux swap / Solaris ls /dev/mapper control cryptswap1

• Game Messaging System Design

  - by you786

  I'm making a simple game, and have decided to try to implement a messaging system. The system basically looks like this: Entity generates message - message is posted to global message queue - messageManager notifies every object of the new message through onMessageReceived(Message msg) - if object wants, it acts on the message. The way I'm making message objects is like this: //base message class, never actually instantiated abstract class Message{ Entity sender; } PlayerDiedMessage extends Message{ int livesLeft; } Now my SoundManagerEntity can do something like this in its onMessageReceived() method public void messageReceived(Message msg){ if(msg instanceof PlayerDiedMessage){ PlayerDiedMessage diedMessage = (PlayerDiedMessage) msg; if(diedMessage.livesLeft == 0) playSound(SOUND_DEATH); } } The pros to this approach: Very simple and easy to implement The message can contain as much as information as you want, because you can just create a new Message subclass that has whatever info necessary. The cons: I can't figure out how I can recycle Message objects to a object pool, unless I have a different pool for each subclass of Message. So I have lots and lots of object creation/memory allocation over time. Can't send a message to a specific recipient, but I haven't needed that yet in my game so I don't mind it too much. What am I missing here? There must be a better implementation or some idea that I'm missing.

• I receive the error 'grub-install /dev/sda failed' while attempting to install Ubuntu as the computer's only OS.

  - by Liath

  I am attempting to install Ubuntu on a box which was previously running Windows 7. I have also experienced the dreaded "Unable to install GRUB" error. I am not attempting to dual boot. I have previously run a Windows boot disk and removed all existing partitions. If I run the Ubuntu 12.04 install CD and click install after the config screens, I get the error Executing 'grub-install /dev/sda' failed. This is a fatal error. (It is the same error as this question: Unable to install GRUB) All the questions I've read while looking for a solution are related to dual boot. I'm not interested in dual boot, I'm after a clean out the box Ubuntu install. How can I achieve this? (For my sanity, please use very simple instructions when responding. I don't claim to have any talent either for linux or as a sysadmin) Additional details copied from comments dated: 2012-05-29 ~15:19Z After booting from the CD, clicking Try Ubuntu, and then sudo fdisk /dev/sda I get fdisk: unable to seek on /dev/sda: Invalid argument sudo fdisk /dev/sdb gives Device contains neither a valid DOS partiion table, nor Sun, SGI or OSF disklabel. Building a new DOS disklabel with disk identifier 0x15228d1d. Changes will remain in memory only until you decide to write them. After that of course, the previous content won't be recoverable. Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite). Command (m for help): I should add the Live CD desktop is graphically bad. I've got missing parts of programs and the terminal occasionally reflects to the bottom of the screen. But I can't imagine this is related.

• No sound after upgrading to Ubuntu 11.10 from win7

  - by Tilman

  just as a prefix to my question, i'd like to note that i'm just now entering the world of Linux (unless you count my android, but that's a very different experience...) i have two computers now that run Ubuntu 11.10, the first of which i've had very little problems with, aside from figuring out the basics. the second, from which i'm writing this question, has (up to this point) only had one problem.... no sound. i've read a couple questions similiar and found little help as the component catalog doesn't have my computer listed. (in fact i'm not suprised this is a pos i had my mom grab from her work before they officially closed the doors behind them) had perfect sound before hand, and no sound now. sudo lspci -v brings up 00:1b.0 Audio device: Intel Corporation N10/ICH 7 Family High Definition Audio Controller (rev 01) Subsystem: Intel Corporation Device d608 Flags: bus master, fast devsel, latency 0, IRQ 45 Memory at ff980000 (64-bit, non-prefetchable) [size=16K] Capabilities: [50] Power Management version 2 Capabilities: [60] MSI: Enable+ Count=1/1 Maskable- 64bit+ Capabilities: [70] Express Root Complex Integrated Endpoint, MSI 00 Capabilities: [100] Virtual Channel Capabilities: [130] Root Complex Link Kernel driver in use: HDA Intel Kernel modules: snd-hda-intel any help would be greatly appreciated, me and my gf just wanna watch a damn movie lol

• Need a good quality bitmap rotation algorithm for Android

  - by Lumis

  I am creating a kaleidoscopic effect on an android tablet. I am using the code below to rotate a slice of an image, but as you can see in the image when rotating a bitmap 60 degrees it distorts it quite a lot (red rectangles) – it is smudging the image! I have set dither and anti-alias flags but it does not help much. I think it is just not a very sophisticated bitmap rotation algorithm. canvas.save(); canvas.rotate(angle, screenW/2, screenH/2); canvas.drawBitmap(picSlice, screenW/2, screenH/2, pOutput); canvas.restore(); So I wonder if you can help me find a better way to rotate a bitmap. It does not have to be fast, because I intend to use a high quality rotation only when I want to save the screen to the SD card - I would redraw the screen in memory before saving. Do you know any comprehensible or replicable algorithm for bitmap rotation that I could programme or use as a library? Or any other suggestion? EDIT: The answers below made me think if Android OS had bilinear or bicubic interpolation option and after some search I found that it does have its own version of it called FilterBitmap. After applying it to my paint pOutput.setFilterBitmap(true); I get much better result

• Debugger for file I/O development?

  - by datenwolf

  Okay, the question title may be a bit cryptic. But it aptly describes what I'm looking for: I think every experienced coder went through this numerous times: You get a binary file format specification, you implement the reader for it, and… nothing works like expected. So you run your code in the debugger, go execute through the code line by line, every header field is read in seemingly correct, but when it comes to the bulk data, offset and indices no longer match up. What would really help in this situation was a binary file viewer, that shows you the progress of your file pointer, as you step through the code, and ideally would also highlight all memory maps. Then you could see the context of the current I/O operations, most notably those darn "off-by-one" mistakes, which are even more annoying when reading a file. Implementing such a debugger should not be too hard. traces on the process' file descriptors/handles and triggers on the I/O functions, to update the display. Only: I don't know of such a kind of debugger to exist. Do I just lack knowledge about the existance of such a tool, or is there really no such thing?

• Floating point undesirable in highly critical code?

  - by Kirt Undercoffer

  Question 11 in the Software Quality section of "IEEE Computer Society Real-World Software Engineering Problems", Naveda, Seidman, lists fp computation as undesirable because "the accuracy of the computations cannot be guaranteed". This is in the context of computing acceleration for an emergency braking system for a high speed train. This thinking seems to be invoking possible errors in small differences between measurements of a moving object but small differences at slow speeds aren't a problem (or shouldn't be), small differences between two measurements at high speed are irrelevant - can there be a problem with small roundoff errors during deceleration for an emergency braking system? This problem has been observed with airplane braking systems resulting in hydroplaning but could this actually happen in the context of a high speed train? The concern about fp errors seems to not be well-founded in this context. Any insight? The fp is used for acceleration so perhaps the concern is inching over a speed limit? But fp should be just fine if they use a double in whatever implementation language. The actual problem in the text states: During the inspection of the code for the emergency braking system of a new high speed train (a highly critical, real-time application), the review team identifies several characteristics of the code. Which of these characteristics are generally viewed as undesirable? The code contains three recursive functions (well that one is obvious). The computation of acceleration uses floating point arithmetic. All other computations use integer arithmetic. The code contains one linked list that uses dynamic memory allocation (second obvious problem). All inputs are checked to determine that they are within expected bounds before they are used.

• Gathering IP address and workstation information; does it belong in a state class?

  - by p.campbell

  I'm writing an enterprisey utility that collects exception information and writes to the Windows Event Log, sends an email, etc. This utility class will be used by all applications in the corporation: web, BizTalk, Windows Services, etc. Currently this class: holds state given to it via public properties calls out to .NET Framework methods to gather information about runtime details. Included are call to various properties and methods from System.Environment, Reflection details, etc. This implementation has the benefit of allowing all those callers not to have to make these same calls themselves. This means less code for the caller to forget, screw up, etc. Should this state class (please what's the phrase I'm looking for [like DTO]?) know how to resolve/determine runtime details (like the IP address and machine name that it's running on)? It seems to me on second thought that it's meant to be a class that should hold state, and not know how to call out to the .NET Framework to find information. var myEx = new AppProblem{MachineName="Riker"}; //Will get "Riker 10.0.0.1" from property MachineLongDesc Console.WriteLine("full machine details: " + myEx.MachineLongDesc); public class AppProblem { public string MachineName{get;set;} public string MachineLongDesc{ get{ if(string.IsNullOrEmpty(this.MachineName) { this.MachineName = Environment.MachineName; } return this.MachineName + " " + GetCurrentIP(); } } private string GetCurrentIP() { return System.Net.Dns.GetHostEntry(this.MachineName) .AddressList.First().ToString(); } } This code was written by hand from memory, and presented for simplicity, trying to illustrate the concept.

• What do I need to Mod a Unreal Engine 3 game?

  - by RoadSideWarrior

  what I am looking for is some advise making a mod for a certain game and how I would go about making it. The game I am talking about is Blacklight: Retribution and what I wan't to know is; Is it possible? And if so, what programs will I need? It is an online only game so I was unsure how plausible a mod would be for it. Plus I have never made a video game before, but I do like the game and I wanted to do some things with it. Additionally, this will be my first time making anything video game related so I would appreciate any advise. To expand a bit, I plan to add something simple at first. A mod that would let you spectate another player in the first person. Then I plan do something a bit more complex where I want to make so the game optionally always records you playing (in short intervals most likely or you would run quickly out of memory). After all that is done I would add items, armor, weapons, and maybe make a map or not I am not sure but this in a shell what I hope to do. I don't know much about these things but I am reading anything I can get my hands on. So if this is overly ambitious or just plain out not a possibility any advise on what I should look to instead will be welcomed warmly. Thank you.

• PASS Summit Preconference and Sessions

  - by Davide Mauri

  I’m very pleased to announce that I’ll be delivering a Pre-Conference at PASS Summit 2012. I’ll speak about Business Intelligence again (as I did in 2010) but this time I’ll focus only on Data Warehouse, since it’s big topic even alone. I’ll discuss not only what is a Data Warehouse, how it can be modeled and built, but also how it’s development can be approached using and Agile approach, bringing the experience I gathered in this field. Building the Agile Data Warehouse with SQL Server 2012 http://www.sqlpass.org/summit/2012/Sessions/SessionDetails.aspx?sid=2821 I’m sure you’ll like it, especially if you’re starting to create a BI Solution and you’re wondering what is a Data Warehouse, if it is still useful nowadays that everyone talks about Self-Service BI and In-Memory databases, and what’s the correct path to follow in order to have a successful project up and running. Beside this Preconference, I’ll also deliver a regular session, this time related to database administration, monitoring and tuning: DMVs: Power in Your Hands http://www.sqlpass.org/summit/2012/Sessions/SessionDetails.aspx?sid=3204 Here we’ll dive into the most useful DMVs, so that you’ll see how that can help in everyday management in order to discover, understand and optimze you SQL Server installation, from the server itself to the single query.

• TraceTune: Improved Comment View

  - by Bill Graziano

  I wanted an easier way to identify queries I’d already looked at so I could skip them.  I’ve been entering comments for each query as I review it.  These comments typically fall into three categories: a change I made, no easy fix available or something needs to be changed on the client.  TraceTune now highlights any statement with a comment in bold.  If you hover over the statement you’ll see the most recent comment for that statement. This gives me a quick way to see what’s new and identify those queries that still need work.  This is especially helpful when I come back to a server after weeks or months away.  These comments help jar my memory and remind me what I’ve worked on. I made the font slightly smaller in some of the tables.  It’s still readable but I’m able to get more of a SQL statement on the screen.  I also got to re-experience the pain of Internet Explorer, Chrome and FireFox all displaying text (and pop-up text) slightly different. Seeing the comments on a trace has been a big help to me.  I often do a round of tuning and then don’t come back to a server until months later.  Having the comments available helps me get back up to speed quickly.

I have Questions floating in my head: Should a mesh could have sub meshes or does the 3d model just store a list of meshes all on the same level Is there one material assigned to one mesh 1:1? What do I have to consider, if I want to store skeletal animations? Btw it's a OpenGL|ES2 iOS game using GLKit. I came up with some basic struct types: (But I think they are way to simple and I need to add padding or change the vector3 to vector4.) typedef union _N3DShortVector2 { struct { short x, y; }; struct { short s, t; }; short v[2]; } N3DShortVector2; typedef union _N3DShortVector3 { struct { short x, y, z; }; struct { short r, g, b; }; struct { short s, t, p; }; short v[3]; } N3DShortVector3; typedef GLKVector3 N3DFloatVector3; typedef struct _N3DMeshRecordSV3 { N3DShortVector3 v1, v2, v3; } N3DMeshRecordSV3; typedef struct _N3DMeshRecordSV3FN3ST2 { N3DShortVector3 v1, v2, v3; N3DFloatVector3 n1, n2, n3; N3DShortVector2 t1, t2, t3; } N3DMeshRecordSV3FN3ST2;

• I can't get grub menu to show up during boot

  - by wim

  After trying (and failing) to install better ATI drivers in 11.10, I've somehow lost my grub menu at boot time. The screen does change to the familiar purple colour, but instead of a list of boot options it's just blank solid colour, and then disappears quickly and boots into the default entry normally. How can I get the bootloader back? I've tried sudo update-grub and also various different combinations of resolutions and colour depths in startupmanager application with no success (640x480, 1024x768, 1600x1200, 16 bits, 8 bits, 10 second delay, 7 second delay, 2 second delay...) edit: I have already tried holding down Shift during bootup and it does not seem to change the behaviour. I get the message "GRUB Loading" in the terminal, but then the place where the grub menu normally appears I get a solid blank magenta screen for a while. Here are the contents of /etc/default/grub # If you change this file, run 'update-grub' afterwards to update # /boot/grub/grub.cfg. # For full documentation of the options in this file, see: # info -f grub -n 'Simple configuration' GRUB_DEFAULT=0 GRUB_HIDDEN_TIMEOUT=0 GRUB_HIDDEN_TIMEOUT_QUIET=true GRUB_TIMEOUT=10 GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian` GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" GRUB_CMDLINE_LINUX=" vga=798 splash" # Uncomment to enable BadRAM filtering, modify to suit your needs # This works with Linux (no patch required) and with any kernel that obtains # the memory map information from GRUB (GNU Mach, kernel of FreeBSD ...) #GRUB_BADRAM="0x01234567,0xfefefefe,0x89abcdef,0xefefefef" # Uncomment to disable graphical terminal (grub-pc only) #GRUB_TERMINAL=console # The resolution used on graphical terminal # note that you can use only modes which your graphic card supports via VBE # you can see them in real GRUB with the command `vbeinfo' #GRUB_GFXMODE=640x480 # Uncomment if you don't want GRUB to pass "root=UUID=xxx" parameter to Linux #GRUB_DISABLE_LINUX_UUID=true # Uncomment to disable generation of recovery mode menu entries #GRUB_DISABLE_RECOVERY="true" # Uncomment to get a beep at grub start #GRUB_INIT_TUNE="480 440 1"

• Dedicated Servers: Is one better then two for LAMP pseudo HA setup? [closed]

  - by bikedorkseattle

  Possible Duplicate: How to find web hosting that meets my requirements? I know there are zillions of commentary about hosting out there, but I haven't read much about this. Our current well known host is having too many problems, the hardware we are on it subpar, and I'm ready to leave. A day of downtime can cost as much as our monthly hosting bill. A month of bad performance is just killing us right now, user and google wise. I'm wondering about running two dedicated boxes for LAMP, one running as the primary Nginx/Apache (proxy pass), and the other as the MySQL box. Running a single box scares the bejesus out of me because who knows how long it will take anyone to fix a raid card or whatever. The idea is to set this up using some sort of failover system using pacemaker and heartbeat. If one server goes down the other can take over for the other running both web and db. There are some good articles over at Linode about this. I have a few DBs that are 1GB+ and would like to load them into memory. Because of this, I'm shying away from a Linode HA setup because for the price I could do it with two dedicated like I described. Am I mad or an idiot? What are people out there doing for pseodu high availability good performance setups under $400/month? I'm a webmaster; I do a lot of things none of it that well :)

• How can I define custom keyboard mappings to resize, move, and manage windows?

  - by fumon

  I just returned to ubuntu (13.04) after a year using OS X exclusively. I love the improvements that have come to ubuntu and unity, and I'm glad to be back. There's just one thing, though... Slate is a simple OS X tool that allows users to quickly create powerful keyboard macros and really take advantage of their screen space. I have to say I was spoiled by it. Even on a tiny laptop, my workflow was never interrupted by changing workspaces or leaving the keyboard to adjust a window, because perfect adjustment was a keystroke or two away. For example: bind h:ctrl;alt;cmd resize -10% +0 # this increases the window's left width by 10% bind h:shift;alt nudge -10% +0 # this moves the window left by 10% You make a big config file, and like vim, tmux, and everything else, it just becomes muscle memory. I can't seem to find a way to achieve anything close to this in linux or ubuntu. I've tried to make do with compiz window settings and the built-in stuff Ubuntu offers, but it's not even in the same realm. Although to be fair, this level of tuning isn't something most people care about. Thanks, guys. :) Any feedback would be appreciated.
