Job Positions

In a discussion at work yesterday, one of my coworkers commented that he expected to see Unix Sysadmin somewhere in the titles of someone who submits their resume for review. With that comment, I had to check out my job history and see what my titles were in the past. These are all job changes at the location I was working at (for example, I was at NASA 13 years but worked for four different companies and my title changed 14 times). Here’s the list:

Senior System Administrator

Network Engineer
Chief Server Engineer
Sustaining Engineer
Senior Unix Administrator

Pretty interesting history there. I pulled it off of my Linked In profile and added a couple of bits that can’t be added because I don’t recall the company name (for example, I was a Photo Editor for a month at one place).

Guitar Time

It’s been a few weeks since I’ve updated the blog. I have a couple of updates I’ll be adding in over the next couple of evenings.

First off, I did stop lessons back in August. I wanted to take a couple of months off to work on the lessons I’d already received and to generally relax and absorb. I’ve also been poking about at different songs to find something I can learn right now with my limited skills.

A couple of weeks ago I hit upon Blue Oyster Cult’s Burning For You. I started with the intro and discovered it was the second guitar and not the lead (which is a bit more complicated). On the positive side, the licks are fairly straightforward. There are 6 different sections with another one that’s spliced into one of the 6. I learned each one pretty well but had trouble with the transitions between them. I finally got enough to try and record. It took several tries but I finally got a reasonably good run through.

I don’t have the YouTube link at my fingertips as I’m posting from my iPad but I’ll snag the link and update the post later.

It’s not as good as each of the sections that I can do. The transitions cause me to get a little fumble fingered, strings get muted or play when I’m moving between notes. I’ll get the technique down with more practice.

Removing the Rear Seat

Last year I did something silly and put the rear seat back on the back of the ‘busa but forgot to connect up the lock cable. So I haven’t been able to get in for almost a year. So far it hasn’t been too much of a hassle however recently I find that one of my tail lights is out (just the running light), I need to refresh my rear brake fluid, and in general, it’s just annoying.

So first off, how do I get into the trunk area. I’ve checked on line in a few places and there’s really no suggestions short of cutting it off. So that’s what I’m going to do.

Note: This is a reenactment after I was done. I put it all back together and went through it again but took pictures. It’s an accurate depiction of the steps I took though πŸ™‚

First off, here’s the rear seat. It’s seen better days so I’m not too concerned if it breaks. I don’t have a replacement handy so breaking would be annoying but nothing I’m going to worry about right now.

I tried pulling up on the seat and I could see the plastic hooks. I couldn’t pull it hard enough to break them though. I snagged a hunk of wood from my scrap pile and propped it up while I retrieved my implement of destruction.

A saw. Yep. With the seat propped up, I used the saw and cut off the hook. Then I did the same thing with the other side.

Next I pulled up on it and decided I’d just remove the rear housing. Once it’s off, I’ll be able to reach the latch and remove the seat. I just have to remove a couple of screws and bolts.

I removed the screws and the Frankenbolts.

I can see the mechanism but can’t get a probe in and over to the left to the latch. So I need to remove the luggage rack bolts. Shouldn’t be too hard.

I was able to get three without too much trouble but the fourth one was really stubborn. Eventually I had Rita pull back on the seat so I had a clear shot at it and finally it came out.

Cowling is off and now you can see the back of the seat. See, there’s a large plastic bit there just to keep miscreants out of your trunk.

It’s a little half box cut across the corners. This side shows the protection is on the side too. Only one way to get in.

From the left side, I can see where the latch is. I pulled one of my hooked probes out of its package and was able to reach

And release the latch

To get the seat off.

Once done, I put fresh brake fluid in and replaced the failed bulb then put the cowling back on. Note that I didn’t forget to put the key cable back in place so I can get in next time.

I’ll have to check out Corbin and get a replacement seat. It’s due anyway.

Guitar Cables

Found a good post on understanding guitar cables:

Well, there are two factors to think about in terms of cable–tone and construction.

The primary reason for tonal differences between cables results from a cable’s capacitance.

Cable capacitance, together with pickup inductance and pot resistance in a guitar equiped with passive pickups, form an oscillating circuit with a resonant peak at a certain frequency. That frequency is usually in the 2khz to 5khz range–above the fundamental frequencies of the guitar but in the “presence” range of the guitar’s upper harmonics.

The more capacitance–either by virtue of using higher capacitance cable, longer runs of cable, or both–the lower the frequency of the resonant peak, the darker and more focused the system will tend to sound. The less capacitance–either by virtue of using lower capacitance cable and/or shorter runs–the higher the frequency of the resonant peak, the brighter and more open a system will tend to sound. This effect will be signficantly more pronouced with lower inductance pickups (single coils) and lower resistance pots (250kohm, for example). It can be a fairly subtle difference that can be perceived numerous ways. For example if a certain peak accentuates frequencies associated with pick attack, a cable that produces that peak in a system can be perceived as sounding “faster.” The effects are also, as you can tell, system dependent. It’s not that a given cable as a tonal quality of its own, it’s the nature of how the capacitance of the cable functions in a given guitar signal chain.

Some people prefer higher capacitance cables like the Canare at 49 pF/ft. Some prefer lower capacitance cables–I use Gepco XBand at 23 pF/ft. It’s all a matter of tuning your system to taste.

There’s no correlation between cost and capacitance. Nor is capacitance a measure of quality. There are plenty of durable cables made from high quality materials at a range of costs and capacitances.

In terms of noise you want a cable that is well shielded from radio frequency and electromagnetic noise–so a double shielded cable with a braided or spiral shield is ideal. Foil shields are not as good. In addition, a cable with a semiconductive PVC shield layer as well–like the Gepco and the Mogami–will shield against microphonic handling noise.

Finally, you need to make sure the plugs are high conductivity and the quality of the terminations and stress relief are good. If you buy your cables from Lava Cable they’ll terminate with great G&H plugs and they do a fabulous job terminating.

So cable capacitance of your choosing, quality copper, well shielded, well terminated– those are the things that make for good cable. “Best” would be impossible to choose. If you’re looking to experiment with cable I recommend trying a bunch of well made cables of varying capacitances–Gepco XBand, Mogami Platinum, Canare, Dimarzio, and the super low capacitance Elixir (10 pF/ft) are all good relatively inexpensive choices–to see what works to your taste in your system.

Guitar Lessons

Ok, it’s been a few weeks since last I blogged about this.

Zack’s been having me learning new techniques and focusing especially on 12 bar blues and embellishments and on breaking out of the rut of the single location on the fret (the b5 blues scales for instance). I’ve been learning all the other scales and modes that Zack passed on last time and picked up a few famous riffs from songs I really like.

Marty Robbins – El Paso – this is the one I’m concentrating on getting through. I have the chord changes but need to finish up on the leads.
Bob Seager – Mainstreet
The Beatles – Day Tripper

Add in:
Heart – Crazy on you
Tom Petty – Breakdown

The funny thing is that right now, they’re all coming along pretty easily. Certainly not the entire song (yet) but I can pull out the main bits that everyone associates with the songs. And these are just going “hey, I could probably play that with 30 minutes of practice” and sure enough I have the basic stuff down quickly and just need a little more practice to get it flowing smoothly. And I can play along with the song on my iPhone πŸ™‚

So last week Zack had me going straight up and down the fretboard vs playing across the fret using one of the scales. Now he normally has me practice with the b5 Blues Scale but occasionally he’ll let me go outside that and into other scales (the b7 and b3 – that’s the ‘flat 3, flat 5, and flat 7’ scales). This time he had me shifting from each of the three scales but up and down. So the B string start with 5, 7, and 8 but keep going up or down to 3, 4 or 7, 8, and 9. These are the positions on the B string. Plus he had me start learning the whole notes on the fret as well but breaking it down by string. So E is open, 1, 3, 5, 7, 8, 10, and 12. So odd, odd, odd, odd, even, even, even. An easy pattern to learn really. And the B string is just as easy. The shift from odd to even is on the 5/6 positions on the fret. And of course since the low E is the same as the high E, you have three strings right away. In looking at the others (A, D, G), they’re easy as well from a pattern point of view. Open, 2, 3, 5, 7, 8, 10, 12 for A. It’s shifted down one additional odd for D; open, 2, 3, 5, 7, 9, 10, 12. And G is easy too. Open, 2, 4, 5, 7, 9, 10, 12. And 12 is the same as Open so you have the next set of whole notes too.

If you’re looking at it, you may not be seeing the patterns but they’re there. A and D are the same as B and E but shifted down 2 frets so shoot, you have 5 of the 6 strings by just memorizing two patterns. Then you just have the one odd one (which really isn’t odd, just shifted down two more frets than the B string). And G is a mirror pattern with an extra at the top. 1 skip 1 skip 1 1 skip 1 skip 1 1 skip 1.

Easy once you see the pattern.

Next is practicing until notes are habitual.

Interesting Facts

First

Failure to develop friendships or seek shared enjoyments with others, lack of social or emotional reciprocity, impaired nonverbal behaviors such as eye contact, facial expression, posture, and gesture.

Engages in one-sided, long-winded speech about a favorite topic while misunderstanding or not recognizing the listener’s feelings or reactions, such as a need for privacy or haste to leave. May appear as disregard for other people’s feelings or insensitive. Displays selective mutism, speaking not at all to most people and excessively to specific people.

Second

Behavior, interests, or activities that are restricted and repetitive and are sometimes abnormally intense or focused. Sticks to inflexible routines, moves in stereotyped and repetitive ways, or preoccupy themselves with parts of objects.

Pursuit of specific and narrow areas of interest.

Repetitive motor behavior such as complex whole-body movement.

Third

Speech abnormalities include verbosity, abrupt transitions, literal interpretations and miscomprehension of nuance, use of metaphor meaningful only to the speaker, auditory perception deficits, unusually pedantic, formal or idiosyncratic speech.

Poor prosody, tangential and circumstantial speech, and marked verbosity. Speech may be unusually fast, jerky, or loud. Speech may convey a sense of incoherence; including monologues about topics that bore the listener, fail to provide context for comments, or fails to suppress internal thoughts. Fails to monitor whether the listener is interested or engaged in the conversation. The conclusion or point may never be made and attempts to elaborate on the speech by the listener is often unsuccessful.

Has an unusually sophisticated vocabulary and tend to use language literally.

Fourth

Demonstrates enhanced perception of small changes in patterns such as arrangements of objects or well-known images.

Poor coordination, have an odd or bouncy gait or posture, poor handwriting, or problems with visual-motor integration. Problems with proprioception (sensation of body position) on measures of apraxia (motor planning disorder), balance, tandem gait, and finger-thumb apposition.

Conclusions

Sold a motorcycle, bought a guitar

We finally got the ad up on craigslist for my 2001 Suzuki SV650S, exactly the same time as someone was looking for just the bike. I posted the ad early Friday for what I thought was a fair price. I did get two immediate answers but then it was flagged and deleted by the craigslist mods. I did post a query to the craigslist forums as to why it was deleted and had several answers; I didn’t post to Boulder, I posted to Denver which is a no-no, I posted that it had been raced which was a no-no, the price was too high, the pictures show racing. So I was going to post it for about $500 less based on the value in Kelly Blue Book. The funny thing is that Rita put the bike up around the same time without telling me (which might have also caused it to be pulled), asked for $300 more than I’d asked and of course $800 more than I was going to ask the second time and had someone come by at 5:30 to look at it, give it a try, and then buy it!

The guy had recently gotten back on a bike after 20 years. His son had purchased (with his own money) a 93 which made it home but was just giving them loads of problems. So dad bought this one for him. They’ll work on the other one and sell it to try and get some funds back.

I need her to make more ads for me. Mine just get spammers and low ballers.

Anyway, after getting the cash and waving to the guys riding the bike off I already knew what I wanted to get. I got on line and searched about for a Fender Stratocaster and the prices. Most were $300 to about $800 for MIM (Made in Mexico) models with a few others for more. With that I headed over to Todd’s Guitars Etc. over on Main Street. Rita says I support local merchants too much πŸ™‚

Todd wasn’t in so I worked with his assistant. I told him that I did want to get a Stratocaster (Strat) and didn’t know what the different models were. I didn’t mind getting a used one if an appropriate one was available but didn’t want to get a special model or edition for the extra bucks as I didn’t want to spent a lot of money. I also wanted to get a Line-6 JM4 Looper. Zack uses one for our lessons and I really like its capabilities for teaching.

Anyway, he set up a Fender Standard Stratocaster (he said it was made in Mexico which is not bad as my telecaster is also made in Mexico), then a Fender American Special, finally a Fender American Standard HSS. The Telecaster (which I currently have) has two pickups (the electronics that translates the string strum to digital), one at the bridge and one at the neck. It has a switch that in the forward position activates the neck pickup. The rear position activates the bridge pickup and the center position activates both. The two pickups have different sounds. The neck provides a softer tone while the rear one provides a twangier one.

Fender Standard Telecaster (the one I currently own but in Placid Blue)

Fender Standard Stratocaster

Fender American Special

Fender American Standard HSS (H=Humbucker double pickup, S=Single pickup)

As you can see, the Strat has three pickups. A neck and a bridge like the Tele but there’s one in the center as well. The switch has 5 positions. Position 1 activates the neck pickup. Position 2 activates the neck and center pickups. Position 3 activates just the center pickup. Position 4 activates the center and bridge pickups. And Position 5 activates the bridge pickup. My Telecaster and the first two Stratocasters have a single coil pickup in all positions (check the pictures; you can see the single row of points under the strings at the neck and center or bridge on the Tele). The American Standard has a humbucker dual coil pickup in the bridge position.

So as he wandered around helping others, I played the three guitars. Honestly the Mexican and American Special both sounded pretty much the same and similarly to my Telecaster but the American Standard sounded a lot different, better in some ways than my Telecaster. The price was a little higher than I wanted to go especially since I was looking at a Line-6 FM4 Looper as well so I asked if there was some play in the price. He went to check and dropped $100 from the total.

While I was waiting, Zack became available (he was teaching on Saturday) so I chatted with him. We talked guitars and looked over the ones I was examining then when I mentioned I was interested in the Line-6 as well in part because he uses it in our sessions, he had me come in and went over some of the things we hadn’t touched on yet. I was already sold but it’s nice that Zack took some extra time to show me the machine.

Anyway, pics of my new guitar!

Pretty sweet I must say.

Lessons

I let Zack (my teacher) know about the upcoming jam session and he shifted the lesson a bit to help me play better with a group. In this case, he showed me the 12 bar blues and a couple of different methods of playing them. I’m still not 100% clear but I’ll be checking out wiki and asking questions as I explore them this week along with the other lessons I’ve had over the past 4 months.

He mentioned also that he had one of his students cancel out of a lesson so he had some time to chat and went out front to hang out with Todd (the owner of Guitar’s Etc) and his assistant (who’s name escapes me at the moment; it’s important though, Jamie for purposes of the story). A couple of weeks ago I let Todd and “Jamie” know about my YouTube video posting and we even brought it up while I was there so he could watch and listen. Zack said that “Jamie” was impressed by my progress and that I was doing very well. That’s cool of course but Zack also said that “Jamie” is a very good player and doesn’t hand out unsolicited compliments often, so πŸ™‚

Anyway, we went through mostly the 12 bar blues along with some accompaniment so I could get it set in my mind and headed on out for the evening.

Pretty cool, I think πŸ™‚

More practice

The previous session with Zack, he gave me a Mode sheet with scales. I’ve learned the Blues flat 3, flat 5 and flat 7 scales. The mode sheet has several extra scales to practice with.

Aeolian Mode
Dorian Mode
Ionian Mode
Locrian Mode
Lydian Mode
Mixolydian Mode
Phrygian Mode

There are two sets of modes that are only off by eliminating the first note so they’re easy to know once you know the first one.

In addition, he provided four common barre chords and an exercise to get me used to moving into position. The barre chord is simple when you understand. Essentially you’re emulating a capo with your index finger and playing a regular open chord with the remaining fingers. It’s a little tough because you’re learning how to play an E chord (for example) and having to shift the fingers one note to play an E major barre chord. The exercise from Zack is to play the A chord then shift to the E major barre chord. Then G and back, then D and back, and finally E minor and back. I’ve been practicing it and am getting the hang of it, although it’s slow to shift.

Finally he gave me two open scales.

I’ve gone through them and have most memorized. I need to use them to play along with my backing tracks or drum kit in order to set them in my memory so I’ll be doing that as well.

The funny thing is Zack may not realize how OCD I am about stuff πŸ™‚ Last week he mentioned, after I showed him that I already knew a couple of the scales that I was in danger of being the fastest adult (see, “adult” again) student to learn all the scales. That gives me some motivation to learn them quickly.

One more thing that’s new. I joined the Telecaster forum just in time. The Denver folks are planning a jam session and inviting all levels of players. I asked if a newbie (December) is acceptable and they said sure, not only that it’d be good experience for me to play with other players. And not only that! Rita has agreed that we can have the session at our place. We have a nice big room (10×40) and suggested June the 5th as she’ll be out of town.

Hey Jeff (I know you’re out there), want to come by on the 5th to jam? πŸ™‚

Awards from Work

I have a couple of traits that work well in a Unix management job. I’m pretty organized. I like to have and create documentation. I don’t like surprises so I’m very proactive in identifying and resolving problems before they become work stoppages. Because of this, at the departmental 1st Quarter meeting, I received the Technical Stewardship award for the Quarter. I have received a few monthly awards that provide a night on the town or a certificate for a few bucks in the cafeteria but this award is quite a bit higher than that.

One issue I find with awards is that they focus on Heroes in the company. Folks who expend extra effort to fix bad problems or be available for grueling work because of short project timelines. You don’t seem to see many awards for the folks that keep things flowing smoothly. In my case, for being proactive. Working on ways to monitor systems effectively in order to identify potential problems before they cause larger problems including server outages.

I was able to get the text for the nomination. I’ve edited out company information as they search for it on the Internet πŸ™‚

I’d like to nominate Carl Schelin for the Q1 2011 Technical Stewardship award. As a senior systems administrator at [Company], Carl has consistently strived to improve the operational efficiency of the systems he administers. He finds ways to streamline processes and create tools that benefit all of [Department]. He has implemented numerous scripts that have automated cumbersome and time consuming manual processes. This has enabled his team to be more efficient and effective while maintaining an emphasis on quality. Every morning, he diligently combs system logs from over 300 hundred systems for anomalies that could flag potential problems. Carl implemented and continually maintains a Wiki that supports a growing user base. He implemented and maintains a status management tool that has benefited many [Department] teams manage their workload. The end users have embraced this tool and continually request enhancements, which Carl readily accepts and implements. Many of Carl’s hours supporting this tool have been done on his own time. Additionally, Carl has implemented a inventory database that has proven invaluable to his team. These are highlighted examples are just a small sampling of the quality work Carl continually produces. Carl is very deserving of the Q1 2011 Technical Stewardship award and his contributions have been a tremendous contribution to [Department].

Pretty nice birthday present, eh? (Yea, it’s my birthday today too πŸ™‚ )

It also came with a surprise inside… a monetary reward. Rita’s first comment was “you’re going to buy a guitar.” Actually, I’m interested in upgrading my small Fender Bullet Amp (practice) with something a bit more beefier. The Fender is pretty old and the treble/mid-range/bass pots don’t seem to have any effect on the output.
