    Alpha
    Due to the power failure, there was the loss of several hours of work. Last night I installed FreeBSD 6.2-RELEASE on an old DEC AlphaStation 200 I have. I had started building a new, smaller kernel for it around 23:30 last night. It had not completed by the time of the power outage. I have restarted that build.
    Any one reading this would reasonably ask, "Why are you not as confused/angry/annoyed with a compile that was not finished in 7 hours as you were about one that took 3 hours?"
    The answer is simple. This AlphaStation is powered by a 100MHz DEC Alpha EV4 CPU and has 64MB of RAM. To the best of my knowledge, DEC made this machine around 1994 or 1995. I expected the build to take a long time; the machine is around a dozen years old.

    Tenth Runniversary
    Today is my tenth runniversary. It's been a decade since I first stepped on that treadmill. Like my first day running, I ran on the treadmill while listening to br\oken. I've had some set backs in my recovery. Not properly rehabilitating the atrophy in the left leg has caused some problems with the muscles around my hip. Listening to my trainer only made it worse. But now I'm taking care of it properly. Like that first day ten years ago, I have a goal I am working toward. This time it is the Dublin Marathon in October. This will be marathon number 13. I don't expect to PR. I think 10 minute miles are a much more reasonable goal at this point, but frankly I'll be happy just to cross that finish line. It's been a long, hard road out of Hell, but God has been by my side and put some amazing people in my life to help me along the way. I have to thank the Giraffes for today. I have to thank the Giraffes for much of my life this last decade. I was heading for an early grave, and they changed that. Giraffes, I thank you from the bottom of my heart and I look forward to running the LTC and many other races with you in the next decade.

    Take back your privacy
    Recent surveys have found that 76% of [the most visited] websites in the world cotain trackers from google and 24% contain trackers from facebook. This has been reported by CNBC, PC World, The Verge, Fortune, and Breitbart.

    Almost anywhere you go on the internet, they are following you, building a profile on you, and selling that information, your information, to the highest bidder. Even if you don't have a user account for google or facebook "services," they've built a profile of you using this surreptitiously collected data.

    It turns out there are some steps one can take to prevent these companies from following you wherever you go. It's not perfect, but it helps a lot. First, don't use Chrome. Second, install ad-blocker plugins for your browser. Third, use your firewall.

    It turns out Google and Facebook are large enough that they have their own Autonomous Systems (AS) composed of numerous subnets. Google owns AS 15169, while Facebook owns AS 32934. Using a little bit of shell, it's relatively easy to look up all the subnets owned by these companies.

    whois -h whois.radb.net -- '-i origin AS32934' | grep "^route:" | awk '{print $2;}'
    whois -h whois.radb.net -- '-i origin AS15169' | grep "^route:" | awk '{print $2;}'


    That's a lot of subnets. Because I have different operating systems on different computers and still want to block traffic to and from all those IP addresses, I've written some simple scripts to add rules to various firewalls. I have scripts for IPFW on FreeBSD, IPTables on Linux, and the Windows Firewall that should work from XP SP3 through Windows 10. I've only tested it on Windows 7 and Windows 10, and it worked in those.

    All of these scripts can be found in this directory. The IPFW and IPTables scripts are self-contained. For the Windows command shell batch files, the *ips.txt files are also needed.

    I have to say, the internet looks very different with these firewall rules in place. There are noticeably fewer advertisements and pages load faster. Embedded YouTube videos and Instagram photos don't appear. Sometimes the frame disappears, sometimes you get a "failed to connect" page appearing in a frame in the middle of a page. (Yes, these rules block YouTube and Instagram; they are owned by google and facebook and reside in the subnets owned by those companies.) On a relatively rare occasion, I come across a site using some sort of javascript or css or something hosted by a machine in one of those ASs and that will be blocked. Sometimes the site handles that gracefully, sometimes it stops being functional. A small price to take back your life.

    Update: Twitter has trackers on a decent amount of sites out there too, so I've added scripts to block Twitter's AS 13414 as well. Those scripts are in the same directories as the others.

    Looking back...
    As I look back at code I wrote a decade ago as an undergrad, I often find lots of little things that can be done better. For instance, in one file I found that reversing the order in which two functions were called would have eliminated a half dozen conditionals from one of the functions and would have resulted in the same expected behavior, but with fewer lines of code and a lower cyclomatic complexity.

    Highway driving
    On the way to the mechanic yesterday, I had the DeLorean out on 287 South. Near one of the Boonton exits, a guy in old Stingray pulled up next to me on my right. I looked over, he looked at me, and we gave each other a nod. I sped up a bit to keep with the flow of traffic and he moved as if exiting soon thereafter.

    This was my longest trip with the DeLorean thus far, and also the fastest I've ever driven it. And no, I still haven't gotten it to 88mph.

    FreeBSD Unix on Dell Precision M4800
    I installed FreeBSD 10.3 on the laptop I recently acquired and almost eveything worked out of the box. The gigabit ethernet and wi-fi coards worked fine and by setting the BIOS to discrete graphics only, the nVidia Quadro was recognized.

    I installed the binary driver from nVidia, because they support FreeBSD because they're awesome like that. The nvidia-xconfig(1) program was useful to streamline the process of getting X.org to use the Quadro.

    There were a few things that did need some tewaking though. First there's the sound card. Because the quadro supports HDMI (in addition to VGA and DisplayPort), it includes an HDA-compliant sound card. This card is recognized before the primary HDA-compliant sound card in the machine, the one that's actually connected to the speakers.

    I did some research and there were some suggestions about using sysctl(8) to control soundcard GPIO pins to connect the nVidia sound device to the speackers but what ultimately worked was using sysctl(8) to change the default primary sound device to the dedicated card. There were a few ways to make this happen but the one I found that actually worked was to place sysctl(8) command lines in /etc/rc.local.

    First I found the device I wanted as the default:

    mforde@gaz:~> cat /dev/sndstat 
    Installed devices:
    pcm0:  (play) default
    pcm1:  (play)
    pcm2:  (play) 
    pcm3:  (play)
    


    Device pcm2 was the one I wanted so I added the following lines to /etc/rc.local
    sysctl hw.snd.default_unit=2
    sysctl hw.snd.default_auto=2
    


    Now when boot completes pcm2 is set to my default and sound "just works" and sndstat shows pcm2 as the default.

    I found ACPI support has some weirdness as ACPI support often does. What I found was that Suspend works from console, but resume doesn't... HOWEVER After I start X ACPI suspend and resume work just fine. Normally I prefer to boot into a console and only start X if I really need it, but because I want suspend and resume to work "by default" I've enabled X to start at boot by allowing the xdm console in /etc/ttys.

    But this had one last issue. See, when manually starting X, I added the -dpi 143 option to get graphics and text to be appropriately sized for my screen. XDM needed to know about this.

    This probably wasn't the best place to do it, but I edited /usr/local/lib/X11/xdm/XServers and modified the call to X(7) to add the -dpi 143 option. Now when Xdm loads at start up, the DPI is set correctly.

    The function keys for adjusting the screen brightness don't work; however, xbacklight(1) works just fine. Similarly the volume keys don't work but I can adjust the volume quite easily with aumix(1).

    I've submitted my dmesg output to NYCBUG's dmesgd repository.

    I suppose I've posted this for two reasons. The first is so I have a record of how I eventually got these little things working in case I have to do it again. The second is in case anyone has similar issues with their hardware; if they happen to stumble upon this, it might give them some hints.

    Don't Call it a Comeback
    On June fourth, I was running in the Tourne on a trail I first ran twenty years ago, a trail I've run hundreds if not thousands of times before. On that morning, my foot came down on a wet rock at just the wrong angle, slipped just enough and I rolled my ankle. Not only did I roll the joint, I came down on it with enough force to break it; a fact I would learn when I final saw a doctor about it on June ninth.

    No surgery was required, but I was unable to run for three months. I was finally cleared to run. The plan was to start with short distances, about a quarter mile, on a rubberized track then build up from there, moving on to treadmills and eventually roads and trails. I was instructed to spend six months rebuilding my 60 mile per week base.

    On the morning of September 11 (a day I will never forget and a morning that will always make me feel a bit uneasy), I took to the track for the first time. I started by walking a mile. As I finished the fourth lap, I said a prayer, asking God to give me the run I needed and the wisdom to know when to stop. I queued up my playlist: AC\DC's "Back in Black" and LL Cool J's "Mama Said Knock You Out." I took my first stride.

    I've been progressing well in the last two weeks; pushing it on some days, resting when necessary. Though the short, slow distances have been frustrating, it feel good to be running again. Every stride I take I'm reminded of everything I love about the sport.

    It's good to be back.

    If my calculations are correct...
    Over the course of the last two years and four months, I've changed considerably both mentally and physically. I lost 108lbs and then put on 6 while marathon training. This 6lbs was purely lean mass (muscle, bone density) and I'm now at about 6% body fat.

    Running is known to increase bone density, and the various forms of exercise I use in my training increased my muscle mass as well throughout this transformation. I've been curious to know just how much fat I lost.

    If my calculations are correct, throughout this process I lost 123.96 pounds of fat and gained 21.96 pounds of bone and muscle resulting in my current net loss of 102lbs.

    Why is this filed under the Running section? Because running was what enabled this transformation to happen.

    A couple of things....
    First, am I the only one who gets freaked out when seeing a Toyota in my rear-view mirror?

    Second, google calculator has failed me. I keep trying to do conversions using Joules and it keeps giving me search results for physics forums with no calculator results. WTF google? WTF?

    Optical Illusion
    I saw this today. I thought it was interesting.

    WTF?
    I'm used to guitarists mocking the bass and bassists. It doesn't bother me too much. But this... This irritated me. A lot.
    Today at work there was a group of people talking about Rock Band and Guitar Hero 3. None of them actually know how to play intstruments but they claim to be great at these games. They seem to believe this entitles them mock bassists.

    • "Oh man, bass is so easy. It's the guitar that's the hard part. Yeah, I'm on expert on the guitar."
    • "Yeah, bass is so stupid."
    • "So It's me, my brother, and my sister. I play guitar, he's on drums, and my sister sings."
      "what about bass?"
      "My friend just got Guitar Hero 3. I'll make him play bass."
      [Both laugh]
    • After making statements indicating this person believes he actually is better than Tom Morello, "After you make Tom Morello or Slash your bitch, they play bass for you."

    chdir(2)
    So today at work another developer many years my senior, with many more years experience than I, came to me with a Unixy problem.
    "When I have a program, how can I have it so the current working directory for all processes it starts isn't the one that it started in?"
    "chdir."
    "No, I want so that if this process starts something like ls, when ls stats 'dot' I want 'dot' to be the directory that process wants it to be, not the directory that process was started from."
    After about 15 minutes of me suggesting chdir while he said that's not what he wanted but then describing chdir, I finally wrote something along the lines of the following

    #include <stdio.h>
    #include <stdlib.h>
    #include <unistd.h>
    
    int
    main (int argc, char *argv[])
    {
      system("/bin/pwd");
      system("/bin/ls");
      chdir("/tmp");
      system("/bin/pwd");
      system("/bin/ls");
      chdir("/etc");
      system("/bin/pwd");
      system("/bin/ls");
      chdir("/");
      system("/bin/pwd");
      system("/bin/ls");
      return 0;
    }
    

    I compiled that, ran it, showed him the output. He said, "Yeah, that's what I want to do."
    I showed him the code.
    "chdir does that?"

    Alpha
    Due to the power failure, there was the loss of several hours of work. Last night I installed FreeBSD 6.2-RELEASE on an old DEC AlphaStation 200 I have. I had started building a new, smaller kernel for it around 23:30 last night. It had not completed by the time of the power outage. I have restarted that build.
    Any one reading this would reasonably ask, "Why are you not as confused/angry/annoyed with a compile that was not finished in 7 hours as you were about one that took 3 hours?"
    The answer is simple. This AlphaStation is powered by a 100MHz DEC Alpha EV4 CPU and has 64MB of RAM. To the best of my knowledge, DEC made this machine around 1994 or 1995. I expected the build to take a long time; the machine is around a dozen years old.

    How long does it take to build a linux kernel?
    It has been a number of years since I built a linux kernel. Slackware 9.1 was the last GNU/Linux distro I used before switching back to BSD. Tonight I put together a machine from some old parts (1.2GHz celeron with 256KB cache, 256MB RAM, 20GB hard drive) and installed Slackware 12. I customized a kernel configuration and attempted to build it. I don't remember the 2.4 kernel taking as long to build as this 2.6 kernel. It took nearly two hours. Granted, this machine is fairly old, but 2 hours? After I complete the tasks for which I needed this setup, I'm going to install an older Slackware with the 2.4 kernel and build that. I may also install FreeBSD and NetBSD and build their kernels. I'd like to get an idea how long it takes to compile other kernels on this rig.

    Race Against Crime and Drugs
    The Hoboken Race Against Crime and Drugs was last night. The Giraffes were split into three three-person teams. Unfortunately, two members were unable to run last night. However, two of the more recent additions to the Giraffes stepped up and joined the race.

    My right calf was still sore at the start of the race, but felt better after about a mile. By that point it was too late and I knew I wouldn't PR, but I did fairly well keeping my time under 21 minutes and finishing number 79 of 609.

    The team consisting of Brian, Liz, and me did fairly well and placed 7th in overall team competitions with a combined time of 1:13:46. Had our second team not been a runner short, they likely would have done well enough for 8th or 9th place.

    Random Running Related Updates
    I ran in another 10K in Central Park this past weekend. I took it a little easy but still managed to take a minute per mile off my time from the Homecoming Scotland 10K last month. It's funny how much better you can perform without food poisoning.

    I have a 3 mile race in the Financial District tonight. It was supposed to be a 5K, but the course was changed due to construction. I'd like to finish in under 20 minutes, but we'll see how it goes. I'm feeling a little sluggish today.

    The Brooklyn Half is coming up on the 30th. It starts in Prospect Park and ends at Coney Island. I'm just shooting for a better time than the Manhattan Half. The weather should be about 50 to 60 degrees warmer for Brooklyn so I shouldn't really have to worry about freezing sweat this time. My pace at shorter distances has improved quite a bit since January so I have that working in my favor as well.

    The running team is expanding. We have a new member for the Giraffes. Hopefully we'll be able to get five men and five women for each NYRR race so we can be ranked in the club standings. I don't expect we'd do very well against teams like NYAC or TRD, they seem to be fairly large teams with a lot of good runners, but it would be nice to see the Giraffes in the rankings.

    Two of The Giraffes (Liz and I) have finished our 9+1 qualification races and are guaranteed entry in the 2010 NYC Marathon. Two more will complete their 9+1 at the Brooklyn Half.

    camaraderie
    Over the past few weeks, I've been running longer loops than I used to. While out and about on these loops, I often come across other runners. There are a few who I see frequently, and others I see not quite as often. Some have obviously been running for quite a long time while others seem to be just starting out.

    One thing I've noticed is that almost all of these people will wave to other runners as they pass each other. It's like when two motorcycles pass each other on the highway, or when a corvette driver sees another on the road.

    There's a feeling on camaraderie; a feeling that, despite having never spoken to any of these people, we share a bond.

    Sunset Classic 5M
    I got to meet Bill Rodgers tonight after the Sunset Classic 5M in Bloomfield. He was signing autographs after the race and actually spedning time talking to people. He spent a good 5 to 10 minutes with everyone, answering questions, giving advice, and just talking about running in general. He signed my race bib and we talked about the course and his diet. He really did put mayo on pizza. Hellman's. Had to be Hellman's. As he put it, "When you're burning 5000 calories a day, you're hungry." It was a pretty good race, I kept pace with the second place female finisher for almost the whole race, with number 3 not far behind. In the last 200 meters or so they both took off and I finshed a few seconds behind them. After the race I thanked the girl I had been running with for making me push myself a little harder than I planned, and congratulated her on her placing. I also made some new friends from work. I met most of the company's running team after the race and we talked about running and stuff. Most of them are in other divisions of the company so I had never seen them before tonight.

    Thoughts on National Computer Science Education Week
    This week is apparently National Computer Science Education Week. Code.org is organizing the "hour of code" to promote teaching of Computer Science and Programming in schools. They're also organizing petitions to make CS courses count as credits in Mathematics or Science for High School graduation requirements.

    In High School, my CS courses were by far my favorites, Programming in Pascal, AP Comp Sci in Pascal, Programming in C++, and AP Comp Sci in C++ ( the language for the exam switched my junior year). I learned a lot about structured code, elegant, efficient code. I learned enough about Data Structures and Algorithms that I didn't have to study for my college CS classes until Computational Structures (Discrete Math II with Scheme, essentially) in my third semester. I had an amazing Computer Science teacher who also taught me Calculus and the proper order of precedence in life: God, Family, Math. I wouldn't be where I am today without that educational opportunity I had in High School. I want others to have that opportunity too.

    However, this is where I differ with the opinion of the Code.org folks. I do not believe that CS classes should count toward the Math or Science requirements. In this state, CS counts toward the "practical or performing art" requirements, I'm assuming under the "practical" label. I think this is a better place for it at the High School level.

    Computer Science is not a hard Science. It's not Physics. It's not Biology. It's not Chemistry. There's a saying that if the subject has science in its name, it's not really a science. That is true with Computer Science. It's not studying the how and why of atoms, of molecules, of living systems, of anything really. It's not science.

    Computer Science is really applied mathematics. I am very fortunate that the college program I went through was very strong in mathematics: Calc I and II, Linear (Matrix) Algebra, Discrete Math, Discrete Math II in the guise of Computational Structures, Probability and Statistics, Theory of Computation, Algorithmic Analysis... the list goes on. All of these mathematical foundations were then applied to a machine, to make the machine carry out a task in an efficient manner. It's those mathematical foundations that are the true core of Computer Science.

    While mathematics is the core of Computer Science and Computer Science is essentially applied mathematics, I do not believe it should count toward the Math requirements. The CS classes would likely detract from other mathematics courses such as Geometry, Trigonometry, and Calculus. These courses are far too important to an education to be replaced by a Computer Science course. Many, maybe even most, High School Computer Science courses focus more on "programming" than the fundamental mathematical theories. They will pick the language du jour and teach you the syntax and semantics. They'll teach about basic data structures like arrays, and linked lists. The AP exam currently focuses not on implementing lists, trees, stacks, queues, and sorting and searching algorithms, but on arrays and lists using Java library calls. This is not math. This is learning Java syntax.

    ... On man pages, a mini-rant
    I really despise the linux man pages. They're useless at best and wrong at worst.

    From the man page for setsockopt: "The include file <sys/socket.h> contains definitions for socket level options, described below."

    1) The options are not "described below."
    2) No, that file actually doesn't contain those definitions.

    On the other hand... The FreeBSD man page for setsockopt does actually describe the options and under FreeBSD the <sys/socket.h> file does indeed contain the definitions.

    Problems with loader.conf

    First the background. The story of how I got into this mess:



    I'm trying to get ACPI working on my laptop under FreeBSD. Specifically, I'm trying to get Resume to work properly. Suspend works, and resume seems to partially work. The fans spin up, the keyboard's backlight comes back on, but no screen. And without video, it's a little hard to figure out what's going on.

    ACPI works great on my server. It's running the same FreeBSD 9.1 x86-64 build that the laptop is, but the biggest difference is that it's an intel motherboard. The laptop is an Alienware, for our purposes, I might as well just call it a Dell.

    I started comparing the ASL output from both machines and noticed some things. First, the Alienware's ACPI implementation looks for the OS to be various forms of Windows or "Linux." The intel ACPI implementation also looks for these Windows variants and "Linux" but it has an additional OS string. It has an entry for "FreeBSD."

    I figured the easiest next step was to use iasl co compile the intel ASL source and load that DSDT onto the laptop.

    I calculated the odds it would work vs the odds I was doing something incredibly stupid... and I went ahead and did it anyway...

    I compiled the asl and I set /boot/loader.conf to override the DSDT with the intel one I had just compiled and I rebooted. At first everything was good. The machine went down, I got the boot loader, and the FreeBSD kernel started to load. Seconds into the kernel load, it rebooted itself. After the second time, I powered off and tried a cold boot. Same problem just as I had feared.

    Now i was in a situation where I couldn't successfully boot because of an error in loader.conf I needed to find a way to edit it.

    And here's the solution:



    The FreeBSD bootloader, like many others, works in stages. At a certain point, it can be interrupted at which point it provides a set of simple yet powerful commands to control various aspects of the loading process. If you still have that default menu at load, I beleive the option to chose is 6. I disable that menu so during a brief countdown I hit escape before the boot loader turns control over to the kernel.

    Once in the boot loader prompt, I entered the following commands:

    unload
    load kernel
    boot
    


    Pretty simple right? The unload command does what it says, it unloads the kernel and any modules loader.conf had pulled into memory. The load kernel command grabs the kernel and loads it into memory... but only the kernel thus ignoring the broken DSDT in loader.conf. And of course boot tells the boot loader to continue booting the system.

    Once booted, I removed the bad DSDT from loader.conf.

    Windows 8.1 in Virtual Box
    I was attempting to run the Windows 8.1 Preview in a VM using Sun's Oracle's Virtual Box on a Windows 7 host. I ran into a minor problem.

    The OS wouldn't boot. I received an error stating:

    Your computer needs to restart. Please hold down the power button. Error Code: 0x000000C4 Parameters: [redacted]

    Looking for the error code online led me to this article describing the issue and a fix. The key to fixing this was running the command:
    "c:\Program Files\Oracle\VirtualBox\VBoxManage.exe" setextradata "" VBoxInternal/CPUM/CMPXCHG16B 1

    The CMPXCHG16B is an instruction in 64-bit X86 processors that allows for atomic operations on octal words.

    Excluding directories while using pax(1)
    My primary disk is failing. There are large segments that are generating low level IO errors during read or write operations. Most of the files written to the bad area were under /usr/ports/ where the FreeBSD Ports collection is installed. A few files were under the web server's root.

    Figuring I'd take care of things prior to the disk actually failing to the point of it being irrecoverable, I purchased a new disk early. I installed it, partitioned it, and formatted it.

    To copy the data over, ignoring the areas that were causing the IO errors, I used mv to "move" the files from the web root under /usr/ports and used the following command as root:

    pax -rwvpe -s':/usr/ports/.*::gp' -X / /mnt/newdisk/

    The -X prevents pax from traversing into mount points that have a different device ID than the one on which it was started. This prevents an infinitely recursive loop from happening when the new disk's mount point would have been hit. It also prevents data on the non-failing disks from being copied as well.
    the -s option allows for sed search and replace scripts to be run. In this example, the : is used as the delimiter and any path matching /usr/ports/* is replaced by a null string. With this replacement all directories under /usr/ports are excluded from the copy.

    Writing

    "You need strong emotion, whether it's fiery or depressed, an extreme state of mind. I think in any art form it's the case." -- Daniel Ash


    Maybe it's my lack of experience. Maybe it's my lack of talent. I tried to sit down and write music for the song known as Ravage in the new naming scheme, but I failed miserably. When I try to force it, like I did tonight, nothing comes out right. I have ideas, I can hear them in my head, but without that inspiration, without that emotion, nothing I produce sounds right.

    I've been too happy recently and it's destroyed my creativity. I get the urge, I have the inspiration, to write when I feel negative emotions. I need anger; I need depression. It is in dealing with these emotions that I am able to write.

    I have tried several times to force myself to feel this way. This usually buys me a few minutes in which I can write, but it often fails. Because the emotions are artificial, the results are mediocre at best.

    I find this situation to be quite frustrating. I want to move forward with this album, but without that inspiration I am unable to do anything.

    In the meantime, I'm slowly teaching myself to play guitar and, to a much lesser extent, a keyboard-style synthesizer. I've also been going through materials my music teacher friend gave me to learn some basic music theory. Hopefully once I find that needed inspiration, or find a way to work without being angry or depressed, this new knowledge will make things easier.

    Revision Control
    One could argue that this should be filed under the Unix category, but this post is more about the album than it is about the Concurrent Versions System.

    Friday night I created a CVS repository on this server to manage album related files. After discussing it with rskutins, we agreed on several key points.

    First, with changes being made a little more frequently than before, it would be best to have some way to track what was going on, and to be able to roll back to a previous version if the changes don't quite work out. Second, we wanted to have a way to organize several files for each song, for instance, lyrics, notes, bass tabs, drum tabs, etc. Last, and maybe the most important reason for the reorganization, we wanted to move away from the numbering scheme that was in place. Each song was numbered from 0 to 17. This was fine until we realized 11 was likely to be the first track on the album.

    Now the album is stored in a CVS repository. This will keep a version history of each file, allow us to simultaneously work on parts of the album, and merge our changes.

    Within this repository we now have a tree structure where each song has its own directory. The directory will hold any and all files related to that song. In an effort to move away from the numbering scheme, an arbitrary naming convention was mutually agreed upon. The songs are now known by names such as Soundwave, Ravage, Frenzy, and Rumble.

    The album is starting to come together. I feel motivated to work on it and recently I've found myself inspired to write. Now if only I had time.

    Omlette listened to the Accidental Mix I posted (of the song now known as Soundwave) and gave me some feedback.

    It sounded ominous. I don't know how else to describe it since I'm not familiar w/ either artist. Oh wait. Were you mixing your own stuff?
    Ominous seems like it could be a good thing given the current direction of the album.

    If anyone else takes the time to listen to it, I'd appreciate any comments or suggestions. If you don't have it, my contact information is on this page.

    Another Demo Update
    Two weeks! Ha! It's been closer to two months.

    A few days ago I had some time so I sat down with the ProTools set up again. After considering some advice from jlight, I decided to record a second track of the bass line. I decided to use my Yamaha for the second track, as I had used my Fender for the original recording back in June. The two instruments have different characteristics in their sounds and the two playing together seems to add a "fullness" to the sound.

    So all I had to do was record 24 seconds of bass and put together a mix. This should take, what, 15 minutes? It took 45 just to record. Once again ProTools repeatedly crashed. When it wasn't crashing, it would report an error and stop recording. Does anyone know if there are updates for ProTools LE 7.1 that will fix this issue? As it stands now, I can't run ProTools for more than a few seconds without disabling multi-core support on my CPU. I have multiple processors. It is a multi-threaded application. It should run better... But I'll save this for that upcoming ProTools rant I keep promising.

    Anyway, after about an hour and fifteen minutes, I got two mixes complete. One of them was accidental and sounds, "interesting." The other is closer to what I had in mind. While I wait for feedback on the actual mix from certain people, everyone is free to enjoy the accidental mix found here.

    If anyone actually listens to it, I'd be happy to accept any comments and criticism.

    Demo -- Update
    Rskutins recorded his drum part and sent it to me via the wonders of TCP/IP netowrking. On Friday night I finally had enough time (and motivation) to start recording.

    I spent a lot of time fighting with ProTools. It repeatedly crashed. Often, when it didn't crash, it simply stopped recording and reported that an error had occurred. I'm remembering this for the ProTools rant that will be coming in the future.

    After 45 minutes I had recorded about 6 seconds of vocals and the 24 second bass line. The next block of Copious Free Time(TM) I have, I'll begin the rough mix of the three parts. Hopefully ProTools won't crash as often during that phase.

    With any luck, it'll be mixed in the next week or two.

    Demo
    In the next few weeks we are going to attempt to record and roughly mix a demo of a short track which will serve as an introduction to the album.

    Currently known as 11, it is a very short piece in 4/4 time at 80bpm. It is in the key of B minor and the spoken words are taken from a quote attributed to Nietzsche.

    What upsets me is not that you lied to me, but that from now on I can no longer believe you.
    This short demo will hopefully get me motivated enough to put more time into the album.

    More information will be posted when it becomes available.

    A Brief History
    Last Summer, my friend, rskutins, and I decided we were going to write an album. He got out his drum machine, being smaller and easier to store and carry than a full kit, and I got out my bass and we started putting together some pieces that were... not good.

    We had little direction, I was afraid to play things outside of my comfort zone, and we had some problems communicating. This project quickly fell apart, but we never completely gave up the idea.

    In March I found the inspiration I needed. I talked to rskutins and we started working on an album again. This time, fueled by strong emotion, both fiery and depressed, I started by writing lyrics.

    Not all are complete, but there are about 15 sets of lyrics for us to use as a starting point. Rskutins has tweaked the lyrics in some places to make them fit a better rhythm while still maintaining the intent of the words. I am quite pleased by what he has done.

    Based on these lyrics we have begun writing short pieces here and there when we feel inspired. Rskutins has laid down some pretty good beats to start with. I've been attempting to learn some basic music theory and trying to apply those ideas to the layers on top of what rskutins has written already.

    And that's where we are now. Still learning, still writing. Our day jobs have slowed down our progress considerably so it could very well take until the Autumn before we're ready to record and mix the album.
