The past few days, I’ve been working tirelessly to get the podcast back up. There have been a number of changes. The first is podpress is gone forever. I discovered this podcasting service called Blubrry PowerPress, and it seems to be way more stable and functional. It took forever because I had to modify every podcast that’s ever been posted since the import from podpress didn’t work. Also, I added ID3 tagging to all the posts so artwork shows up now. There are still some issues to work out. First, in order to add a podcast description, our webserver needs to be upgraded to php5. Not sure why, but I’m working on getting that done soon hopefully. Also, I’m working on updating the artwork for the iTunes store and for the ID3 tagging. We’ll see how that goes. Please use the “contact” link to report any issues you might have.

Unfortunately, the WordPress 3.0 upgrade has broken quite a few things on the site including podpress, which is the plugin I use to post MTPB. I’ve been working on it for a while now and I can’t figure it out, and since this version of WordPress hasn’t been out for very long, there isn’t really any information out there on this problem. I’ll likely have to figure out a way to downgrade to the previous version. I have Soundwave practice tomorrow so it will likely stay broken through Thursday or Friday depending on how long it takes me to fix it. I’ve got the new MTPB podcast ready to post too! Please pray for me that I’ll find a fix quick.

I sat down at the piano last week ready to record the next podcast, and due to all the cold weather, it’s really caused my piano to get out of tune so 10 minutes into recording, I decided to wait until the piano gets tuned. It has been extremely busy at work the past couple of months because we are moving our datacenter to San Antonio and I’ve been put in charge of bringing up the network which is pretty complex so I’ve put in probably over 150 hours this week and last working and driving back and forth to San Antonio. I actually have to go in today to wrap some stuff up before Monday so I’m afraid that the podcast has been postponed yet again.  I hope the archives can provide enough music for prayer in the interim. God bless.

I mentioned in the last podcast that I would blog about the new method of recording used in the last podcast. Instead of the Roland R-09HR, I used a balanced pair of Rode NT5′s with the Apogee Duet as an audio interface. The results were pretty surprising.  Normally the EQ I use will have massive peaks and valleys throughout, but with the NT5′s, very little EQ or anything else for that matter was needed.

This is a good shot from the front. You can see the XY pattern used.

This shows the XY pattern from the back, and the placement inside the piano. I actually used Westone in-ear monitors, which completely block out any sound and listened to what the mics picked up using various positions over the piano strings and soundboard. This is what I came up with.

Here’s the MacBook Pro running Logic Studio 9 with the Apogee Duet ready to go. This thing is so quiet!

Because of Thanksgiving weekend, I’ll be taking this week off from the podcast to spend some time with the family. Next Saturday, Soundwave is going to record one of our new songs here at the Maestro Music studio, but I’ll try to get another podcast recorded next Sunday after church. Happy Thanksgiving!

CCIERouting_and_Switching_UseLogoThanks to everyone for their support. Below is the story of my journey I posted on one of the CCIE study groups I followed for years while preparing:

My journey began a little over 5 years ago.  I had already obtained some Cisco professional level certs and figured the CCIE couldn’t be much harder so I booked a lab and a bootcamp with IPexpert.  I had some experience, but nowhere near the skills necessary for a CCIE candidate, which I realized the first day of Scott Morris’s bootcamp back in 2005. That was back when ATM and ISDN were still on the exam. At any rate, I barely made it through layer 2, and got stuck on layer 3.  I knew I didn’t have a chance. 

 3 years later after gaining some valuable experience on the job, and putting together a lab of 7x 2811’s, 5x 2600 series (2 of them XM’s), 3x 3560’s, and a 3550, I started hitting the books.  I purchased the IPexpert Blended Learning Solution, and worked through all 3 volumes (Volume 1 I worked through twice), watched the videos and listened to the audio throughout my study time, and read the following Cisco Press books:

 Cisco QOS Exam Certification Guide

CCIE Routing and Switching Exam Quick Reference Sheets

Routing TCP/IP, Volumes 1 and 2

Internet Routing Architectures

CCIE Routing and Switching Exam Certification Guide

Developing IP Multicast Networks

 I started studying on a regular basis after I passed the written back in October of 2008, but really started hitting it hard the day they announced the change and I scheduled my lab date.  For the OEQ’s, I used the IPexpert as well as the Internetwork Expert Core Knowledge sims.   I’ve studied for more than 500 hours since May.  I put everything on hold – the band, my “music to pray by” blog (http://www.musictoprayby.com), and my wife and 1 year old child.  The only thing that didn’t go on hold was God and serving at the church.  Yoko and I sacrificed celebrating our 10 year anniversary on September 25th so that I could wrap up preparing for the lab.  My wife is awesome – she did this without complaining once.  I couldn’t have done this without her support.

I just want to thank my LORD and Savior, Jesus Christ for being my inspiration and giving me the abilities I have.  I also would like to thank IPexpert for putting together some of the most challenging material I’ve ever put myself through.  After working through all the labs and understanding the solutions, I actually felt a little over-prepared, which is certainly not a bad thing.  I would also like to thank everyone in groupstudy for helping me out with the questions I posted.  I didn’t participate much compared to a lot of the other professionals who are a part of this awesome community, but I’ve been reading religiously for over a year now, and that knowledge gained from yall has been a tremendous help!

Here’s a little bit about my lab experience:

I flew into San Jose from Austin on Wednesday just so that I’d have Thursday to relax and get mentally prepared for the big day.  On Friday morning, we met the proctor – I actually remembered him from my last lab date over 4 years ago.  He showed us to the lab, and to my surprise, there were these really nice Dell 24” displays at each station.  I remember them being junky CRT’s the last time I was there.  The OEQ’s were not super easy, and if I would have relied solely on my lab experiences, I probably would not have passed.  I think the reading I did certainly prepared me for these more than anything else.  The irritating things were my keyboard’s space bar made this squeaky sound that was really annoying and the guy next to me had this habit of humming, but once I started my lab; I zoned in and finished in a little over 4 hours.  At this point, I’m freaking out thinking there has to be a page missing or something.  So I took a little over 2 hours going over everything again very carefully and found a few mistakes.  At 3:15, I figured it was pointless to stay any longer so I did another round of tclsh pings and write mems and left.

Thanks again to everyone who has already congratulated me.  Now, it’s on to the SP track before they add OEQ’s!

Well, I just got the piano tuned yesterday, and I can’t wait to do the next MTPB podcast!  Look for it to be posted sometime on Sunday.

Something unexpected happened last week. I found out that the CCIE Routing and Switching Lab Exam  is in for a huge change on October 18th. For those of you who don’t know, I’m a Sr. Network Engineer at AT&T WiFi Services. A simple description of my day job is basically building and maintaining the Internet. It’s fun and very complicated. In order to further my career, I’ve committed to passing the CCIE R&S Lab exam.  My plan was to take the 8 hour exam sometime in December, but that all changed the day Cisco announced the changes coming in October. I registered the day it was official, and the closest date I could get was October 2nd, which is 2 months earlier than I had planned on taking it. This certification has been compared to a doctorate degree, and is referred to as “the MBA of Networking”. Candidates literally spend hundreds if not thousands of hours studying for the exam, and I have less than 5 months to get prepared.  My plan is to spend at least 40 hours a week from now till the day I take the exam which means I will have no social life. This also means that the podcast and any music or recording outside of Sunday morning church will not be possible if I intend to get in the number of hours of study I need to pass. Part of my plan was to spend a few hours a day at work studying but due to the AT&T acquisition, there are a number of projects on my plate that are due over the next few months that will likely reduce if not eliminate any free time I had at work to study. I truly am sorry about this, but I believe that the reward at the end of this journey will be well worth it.  As soon as this is over, I will do my best to go back to weekly podcasts. God bless!

Today after church, we had group, left there a little after 3:30, Sanban fell asleep on the way home, so we took a nap for about an hour and a half, then Yoko and I sat down for a while to talk about what to do about our house.  We have lots of repairs to do – electrical outlets on the outside of the house are dead, fence was blown down by the strong winds we had the past couple of days, etc., then my dad called me and we chatted for a little over an hour about the beautiful property surrounding the Austin area.  Yoko and I came really close to buying a house on a postage stamp lot in Buda, and decided not to because it didn’t make sense financially.  My dad did convince me that a better investment would be a home on some acreage.  At any rate, we’re putting SanBan to bed right now and we haven’t even eaten dinner yet.  It doesn’t look like I’ll be able to do the podcast today, which kills me.  Something else I haven’t blogged about – one of my goals is to get the CCIE certification by November, which is going to require practically every spare moment I have studying.  I’ll blog more detail about this sometime in the near future.  I know the podcast is eternally important, and I do plan on continuing it, but I feel that it is necessary to cut back to once every 2 weeks since it is a 4-5 hour commitment of my free time on the weekend, and free time is very scarce right now with family, church, studying, and the band.  I hope you understand, and I do plan on going back to a weekly podcast as soon as I obtain the CCIE certification later this year.  When August hits, I may have to go to monthly podcasts through November or December since my studies will pick up the closer I get to the test date.  If all goes well, I’ll start January of ’10 with weekly podcasts.  Another personal goal is to compile an album of “The Best of Music to Pray By”, and get it mastered, duplicated, and professionally packaged with album art and everything.  I hope to have that album available by the middle of 2010.  That will require an enormous amount of time since it will involve listening to hours of the MTPB podcasts, going back to the original uncompressed files, and preparing about an hour’s worth of music for mastering, but I believe it will totally be worth the effort.  Please let me know what you think – good decision, bad decision, priorities out of wack?  I’d love to hear what ya’ll think!  At any rate, This would be my weekend off (involuntary ;-) ) so I will put the podcast at the top of the priority list for next weekend.

If you’ve heard the song, “Harder, Better, Faster, Stronger” by Daft Punk, then you know what I’m talking about.  Anyway, Jeremy enlisted my help in doing a version of this song for a youth conference coming up this week.  He already had an instrumental track so all we needed to do was record vocals with the new words that fit the theme of the conference and apply the right vocoder synth sound.  Simple enough right?  I figured a couple hours of work, but it ended up taking a weeknight and most of yesterday.  At first, Jeremy actually tried to sing the part.  Well, I wouldn’t actually call it singing.  In fact, I was very tempted to post the audio of that first take, but Jeremy would probably kill me.  After trying that a couple of times, we realized that with the vocoder synth, you just speak the words and the synth does the rest.  Well, it’d be that easy if there was a MIDI track of the song anywhere in existance, but there isn’t – at least not on the WWW so I had to record it myself.  Once the MIDI track was done, I broke out the EVOC 20 PolySynth that comes with Logic Studio 8 and started tweeking.  I literally spent hours trying to come as close as possible to the original and learned quite a bit along the way.  Here are the settings I ended up with:

evoc_20_polysynthAnother key is to use lots and lots of compression on the original audio track as well as the software synth track.  I’ve read somewhere that distortion on the original track can have a nice effect as well.  Oh yeah – and don’t forget about your EQ – you can really manipulate the end result with an EQ.  If anybody out there is interested in acquiring the MIDI, feel free to drop me a line.  I’d be happy to share it.  Here is how it turned out:

First of all, sorry for the downtime today for those of you who couldn’t get the podcast, download, or play from the website.  This was due to me attempting to switch hosting providers.  I ended up switching back since I couldn’t figure out why the podcast was breaking. I don’t think I’ll be trying to switch again for a while – so much time wasted on this. Since the change involved playing around with DNS, reaching the site may be a little sketchy for the next 24 hours until the proper DNS records get propagated all over the world.

With regards to the “Play Now” feature - I discovered that the problem had to do with the 48k sample rate of the podcast so i had to go through all 19 previous podcasts, convert them back to wav format with a 44.1k sample rate, then back to MP3.  It took a while, but it’s been done and the pages and posts have been updated.  The good news is the file size will now be a little smaller with no noticeable loss in sound quality.  All future podcasts will now be posted with a sample rate of 44.1k. Wow – I had no idea that maintaining a website could be so much work! :-)

flashThis has actually been broken for a while. Some of you may experience garbled audio if you try to use the “Play Now” feature available in the MTPB Blogs, downloads, and archives. This appears to only affect Flash Player 10. A workaround would be to either use the “download” link, subscribe to the podcast, or downgrade to Flash Player 9. I’ve tried this version on both a Mac and a PC and it works fine. I hope to find a solution soon and will let you know when it’s fixed. Sorry for the inconvenience.

I was able to search through the text of a database backup from a month ago and replace the PodPress settings record in the corrupted database!  I don’t know why I didn’t think to try this last night/this morning.  At any rate, the iTunes Store has the podcast cached from when things were broken so if you try to subscribe through iTunes right now, it probably won’t work until they update the podcast, but things should be good to go by tomorrow.  The “play” and “download” links on the website are working, and if you use anything other than iTunes for podcasting, you should be good to go as well.

On a side note – you might be wondering what kind of vacation could possibly be had in Sonora, TX. Well, I’ll be sure to blog all about it when I get back. :-)   God bless!

Last night around 8:00 PM, I was trying to fix the MTPB WordPress Stats.  It hasn’t been working since I updated to 2.6.5 a few days ago.  I read something about modifying the theme to fix it.  When I did this, Podpress broke and began complaining about the same thing.  I worked on it until 4:00 AM this morning and tried everything I could think of including restoring the website completely from a backup.  I’m pretty sure it has to do with a corrupt database entry which I do not have a recent backup of.  At any rate, I am completely exhausted and fed up with Podpress.  I have totally run out of ideas so I will ask around and try to get some help on this.  Unfortunately, I leave tomorrow with my brothers out to Sonora on vacation and will have very little time to work on this till I get back next week.  In the meantime, the podcast directory where you can manually play and/or download the audio files is here.  I’m really sorry about this.  Also, there won’t be a podcast this week since I’ll be out of town.

Last night at practice for church, there was a fellow keyboardist there who showed a bit of interest in my setup and was impressed with some of the sounds, so I thought a blog about the “gig rig” might be interesting to some of you.

The guts: I do something very few live keyboard performers do, but more and more are moving toward.  I trust a standard computer to produce live, real time sounds as I play.  I use a program called Main Stage by Apple.  It is bundled with Logic Studio 8, and has literally changed the way I think about keyboards. It is fully customizable based on the controller hardware you have and comes with a huge selection of software synthesizers and samplers.  You also have the ability to add 3rd party software synths for even more sounds.  I was given IKMultimedia’s Philharmonik which has some beautiful orchestral sounds as well as some very real grand piano samples.  The install is almost 50 Gig, but the sounds that are produced are the closest to the “real thing” I’ve ever heard to date.

The computer: A very solid Apple MacBook Pro with a 2.4 Ghz Intel Dual Core proc, 4 Gig of RAM, 160 GB 7200 RPM HD, and a high res 1920×1200 display.  Even with this much power, Main Stage can still buckle if too many sounds or effect plugins are layered so there is still a balance to maintain.  Part of the problem with processing power is the USB audio interface built into my VX8.  If I were to move to firewire, this would help substancially, but so far I’ve been able to work within the constraints.

The Bottom Stack: My main controller is the CME VX8 88-key controller with a lot of nice features, but it weighs a ton!  This doesn’t really make it ideal for a gig rig, but it does help me stay in shape.  The weighted action has a good feel, but it makes a clicking metal-on-metal sound when certain black and white keys are played in sequence which can be annoying.  I swapped this keyboard out 3 times and every one of them did the same thing so it appears to be a manufacturing defect.  Another problem is the USB ports.  I’ve only been using this keyboard for about 6 months and I can already tell that the USB ports are going to wear out eventually and I’ll be forced to move to another audio interface, which will likely be the Apogee Duet.  Other than these flaws, this keyboard has served me well so far this year.

The top stack: A Korg Triton Extreme.  Ever since Korg came out with the Triton over 7 years ago, I’ve owned one.  It started with the standard Triton Pro x, then to the Trinity, then the Triton Studio Pro, and now the Triton Extreme.  This keyboard makes up for the heaviness of the VX8 weighing much less, but only providing 61 keys – enough to play organ riffs all night long! My favorite thing about this product line is the synth pads you can create.  This also can be used as a backup if my laptop decides to stop working, which has happened once or twice when I first made the move to this rig back in December of ’07. It also has a USB midi out so I have it configured it as a controller in Main Stage as well.

The Sound: I prefer to use my Westone ES2 in-ear monitors if the venue permits, but if not, I use some Yamaha MSR100′s.  I run everything through a Mackie 802-VLZ3 mixer which opens up a number of options.  One of the options is to restrict the output to only my keyboards if I have an overall mix being fed into the mixer or if I feed the output of my R-09HR to hear the “room” when I use the Westones.  The mixer also has XLR outs which eliminate the need for direct boxes.

The stands: For the keyboards, I use the Ultimate V-Stand.  I do have the laptop attachment, but the vibration was a bit much so I moved the MacBook Pro over to an insTand, which has worked out nicely.  For the Yamahas, when I use them, I have some standard 45 degree angled guitar amp stands.  They’ve held up pretty well so far.  The one thing that hasn’t held up well is the second tier of the V-Stand.  The adapter to attach the second tier stripped out after about 6 months of use.

Well, that about covers it.  If you have any questions or comments, feel free to leave them.  I’d be happy to answer any questions or discuss any of the parts that make up the gig rig with you.

After waiting over 2 weeks, I finally received confirmation from (ISC)2 that I passed the CISSP exam!  Thank you for your prayers and support.

The iPhone 2.1 update came out today.  I’ve upgraded but haven’t had a chance to see if there’s an improvement in 3G performance.  Apple said this update is supposed to fix the 3G signal problems as well as the following:

  • decrease in call set-up failures and call drops
  • significantly improve battery life for most users
  • dramatically reduced time to backup to iTunes
  • improve email reliability, notably fetching email from POP and Exchange accounts
  • faster installation of 3rd party applications
  • fixed bugs causing hangs and crashes if you have lots of 3rd party applications
  • improved performance in text messaging
  • faster loading and searching of contacts
  • improved accuracy of the 3G signal strength display
  • repeat alert up to two additional times for incoming text messages
  • option to wipe data after ten failed passcode attempts
  • Genius playlist creation

I went ahead and got the Roland Edirol R-09HR for recording the Music To Pray By blog.  I’ll also be using it as a stereo mic when I use in-ear monitors during live performance in order to hear the room since the Westones block out everything.  I currently do this with the R-09′s and it works really well.  I’ve already recorded some of this week’s posting with the R-09HR, but haven’t had a chance to compare yet.  I hope it’s an improvement in sound quality over the R-09.  According to Roland, the mic pre’s are supposed to be better, and it records at 24 bit 96k, which is double the sample over the older version.  I’ll be listing the R-09 on eBay this Tuesday to recoup some of the costs. Why Tuesday you might ask?  Ask me in a comment and I’ll elaborate…

Because of hurricane Ike, I decided to pull my antenna that was mounted on the side of my house and move it inside, and surprisingly enough, Windows Vista Media Center is reporting better signals inside at a lower altitude than what I was getting outside with it mounted much higher.  It must have been the attenuation of the added cable and grounding required.  On a side note, my family is in the path of this hurricane so please be in prayer for them as they ride it out.

Week 8′s podcast will be posted sometime tomorrow as long as we don’t loose power.  Based on the current Ike forecast, that shouldn’t be an issue – just a bunch of much needed rain.

Tech talk…

I have some tech stuff to blog about:

CISSP

First, as some of you know, I’ve been studying very hard for the past few months for the CISSP examination, which turned out to be a big waste of time since most of what I studied was material NOT on the exam.  I woke up early this morning, drove to San Antonio, sat down to take the test at 8:45 AM and didn’t leave till 2:30 PM.  It is by far the hardest written exam I’ve ever taken.  Also, they must have recently changed the structure of the exam because I was expecting to see a lot more technical questions, and there were around 5 out of 250.  At least I know I got 5 of the questions right! I won’t find out what my score is for a while.  They told me up to 6 weeks, but I’m sure I’ll blog or twit about it as soon as the results come in.

Secondly, I have to apologize for the most recent podcast.  I forgot that my R-09 was set to record to MP3 instead of WAV.  This got changed when I used it to record a practice for the upcoming Austin Jazz Music Festival gig next weekend and I needed extra recording time.  Of course, an R-09HR with a 32GB SD Card would fix this.  Okay, I pledge to use any donations minus 10% for tithe towards the purchase of one! :-) I’ve been listening to the podcast as I write this post and I’ve noticed that it has a darker sound than my previous podcasts.  I had the R-09 positioned like I always do.  It either had to be converting MP3 to WAV while importing the audio into Logic Pro, then back to MP3 for the post, or the way the R-09 handles recording to MP3.  There may have been some stuff I could have done with EQ, but initially I didn’t really hear any difference on my studio monitors.  I should have done a comparison with previous podcast audio prior to bouncing…  Lesson learned.

Lastly, as you may have heard, the iPhone 3G signal problem has been narrowed down to the Infineon chipset used in the manufacturing of the new iPhone.  Apple has been very quiet about this whole thing, but Steve Jobs wrote a letter to some complaining customers that this issue affects approximately 2% of iPhone 3G owners which comes out to around 60,000 iPhones.  Personally, I believe it’s much more than that since I haven’t seen an iPhone 3G that didn’t have the same issue as mine, plus like I mentioned before, I’m on my 3rd one.  On a positive note, Jobs assured the customers in the letter that this issue can be resolved with a firmware update.  Unfortunately, the recent 2.0.2 update didn’t resolve it, although it did fix some problems I was having with software hanging and GPS seems to come up faster.  I really want my 3G though!  Come on Apple – help out a loyal fan!

Tags: , , ,

Ok… So I know what you’re thinking right about now…  What in the world does signal problems with the iPhone 3G have to do with Music to Pray by???  Well, I could probably make something up, but I won’t.  I hope to use this blog to discuss every day techie stuff too.  Please leave a comment if you think this is a horrible idea, and I’ll stop. :-)

For starters, I am on my third iPhone 3G, and I am still having a huge issue with 3G signal even when I’m in the center of Austin, which is supposed to have complete coverage based on AT&T’s 3G coverage map.  There have been a couple of articles on CNet News regarding this issue, and have you seen the Apple Discussions thread????  I think there are almost 2,000 responses now.  Below are screen captures I did on my iPhone one right after the other as you can see by the time, and I was here in my home office with the iPhone completely stationary.  For those of you who don’t know where I live, I’m not even a quarter of a mile from I-35 in Kyle, TX which is well within the 3G coverage area…

Here are my thoughts based on what I have read.  If the next version of the iPhone software release does not contain a fix, it is likely a hardware issue.  The fact that there wasn’t a fix in the 2.0.1 release, and Apple’s lack of admission that there is a 3G reception issue somewhat makes the case for a hardware problem which would really be a bummer for all of us early adopters…  I guess it’s the price we pay unfortunately.  Any comments?

I just wanted to talk about the recent music post and bring a couple of things to your attention. There are a few things that are different between week 1 and week 2′s recording. On the Roland R-09, I used the auto gain control with a low mic gain setting for week 2 whereas with week 1, AGC was off, and I had the mic gain set to high. This resulted in a more balanced recording with much less overhead to work with so a lot of noise was induced when I normalized the track. Thanks to Micah Petrea‘s hookup last night, we were able to reduce the noise a little. I also used 24 bit 48k during week 2 vs. 16 bit 44.1k for week 1. Of course, I compress to mp3 at 192kbps using VBR after touching up a little, but some would argue starting with a higher quality signal can make a difference. Next week, I’ll try AGC with the mic gain up and see what happens. If you’d like, comment here which week sounds better in your opinion.
