Spending Money On A Silly Idea

Posted by on January 12, 2020 No comments

One of the more dangerous things in this world is a man with extra time and extra money.  A danger to himself and to the world at large.  If it’s not an actual, you know, danger, then it’s just stupidity – a different kind of danger.  Semantics aside, I have some extra time and some extra money and wanted to get an answer on something.  With the entire knowledge and experience of the Internet failing me, or at least failing to convince me, I set out to get my own answer.  Am I going to change the world with my soon-to-be-found knowledge?  Fuck, no.  It’s so trivial, it hardly even matters to anyone.

To even appreciate what I am seeking, you have to be pretty involved in my hobby of CD collecting.  If you’re not, then the rest of this post won’t even really interest you.  Further, you have to be fairly experienced with technology and computers, otherwise, this won’t really make much sense.  So, warnings provided, now for the explanation.

In the early days of CD manufacturing, some CDs were pressed with "pre-emphasis", which is a special equalization.  CD players as part of their manufacturing specification had to be able to detect pre-emphasis and apply a reverse equalization (de-emphasis) when playing back these early CDs.  Sounds pretty simple, right?  Over time (actually very quickly), pre-emphasis use was discontinued, so all CDs today don’t have pre-emphasis anymore.  That’s fine for the general public, but somewhat of a nuisance for early CD collectors like myself.

Now that you understand the situation, here is the problem in a nutshell: CD players – and especially computer CD-ROMs – do not have the capability to detect pre-emphasis anymore.  So if you play back an early CD, you do not get the corrective equalization applied to the music, which makes it sound thin and harsh.  This also applies to CDs that you rip on your computer.  There are software plug-ins that can apply de-emphasis to the files after they have been ripped, so the problem can be somewhat mitigated.  But aside from using your ears, because the CD-ROM cannot detect the pre-emphasis, you can’t know for sure if the CD you ripping has pre-emphasis.  Again, not a problem for anyone but early CD collectors.

And so what I am looking to know is:  I want to be able to detect pre-emphasis on CDs in my computer.  Thus, my project.

I’ve discussed the CD history, now for the computer history.  Early computer CD-ROM were literally mini-cd-players.  They had a headphone jack and a volume control and some even had a play button in addition to the eject button.  Additionally, on the back of the drive, there was a jack to run the audio from the CD drive to the computer’s sound card.  These old drives played audio CDs in analog.  They had build in DACs (digital-to-analog converters), but you can be pretty certain they were not of the quality found in home stereo CD players.  Still, because they were doing the digital conversion, they also had to support handling pre-emphasis.

As technology moved on, pre-emphasis was no longer a concern and also, Windows began reading the audio from CDs digitally.  So drive makers dropped the headphone jack, dropped the DACs and dropped analog output completely.  It made the devices cheaper and audio could be read at the drive’s full speed instead of the 1X speed of analog.  Technologically, a great step forward.  But in the process of simplifying the device, they removed the capability to read pre-emphasis at all – it wasn’t needed.

But now, I want to get an old CD-ROM that has a DAC and analog output so I can hopefully detect pre-emphasis when ripping a CD.  The problem is that all those old drives use the IDE interface, which is long, long obsolete.  Computers now use the SATA interface.  But that’s only a stumbling block because of course someone has made an IDE-SATA interface converter.  So, technically, everything is still possible.  I don’t have to go to the extreme of building an old Pentium computer from parts salvaged from the 90s, thank god.

Naturally, EBay is the order of the day.  Because this project is only for curiosity, I’m buying stuff as cheap as possible.  For $16, I have a 19-yr old CD-ROM and an interface kit coming by next week.  Then it will be a challenge to see if I can get my computer to see the new (old) drive, then it will be a challenge to see if the ripping software will talk to the new (old) drive, and if it does, will the drive report the pre-emphasis information to the software.

So, there’s still some unknowns.  For the $16 I’ve spent, I’ve purchased a lottery ticket for either frustration or a jackpot of, "oh, neat."  What will I do with this incredible information?  Well, obviously, I’ll share it whenever I can.  It will be a good data point for my posts on Relative Waves and I’m sure some other collectors would like to know which CDs have pre-emphasis.

More Words, Now With More Security

Thanks to the regular march forward of technology, I can now get a free SSL certificate for my websites.  The process isn’t exactly simple, and it’s not convenient, but the results are effective.

The process is more geared towards Linux servers, but with a few additional steps you can create a certificate for Windows servers.  I’m sure I’ll figure out a way to simplify/automate the process and make it easier over time.  The lack of convenience is that the certificate expires every three months instead of every two years.  That’s a fairly significant investment of effort to keep this going.

But, I am a believer in security and privacy, so you can now rest easy knowing that the pages you’re requesting here are not being snooped on by anyone else.

Road Trip In ATL

Posted by on January 8, 2020 No comments

Over the weekend, I made a road trip up north to Atlanta to see some friends and explore some shops for CDs.  Before I left, I did some research on places I wanted to visit.  As is my default, I used Bing.  A lot of people dismiss Bing as useless, but it’s probably for the same reason that I dismiss Google – I just don’t use it.

Bing Maps has a neat feature where you can save places into an itinerary, and it will create driving directions automatically from the list.  This is what I came up with for Saturday’s run.

image

The downside to using Bing Maps is that it’s not part of Android Auto, which is how I do the navigation in my car.  In the interest of being fair about the routing capabilities of Google vs. Bing, I took a look at Google maps to see if I could have done the same thing there.  What I found was that you can make a custom list of places, but you can’t automagically turn that into a multi-waypoint drive.  I suppose you could keep the list open and work your way through the items, choosing each in turn as the next destination.  So, it’s just a different way of accomplishing the same goal.  I’m not going to say "Google sucks, Bing rules" because that’s just stupid and we should all be more adult about this.

On one of the stops at CD Warehouse – a chain store that has been bankrupt for almost two decades; I have no idea how these ones are open – I found a CD to purchase.  It was a Japan pressing of an Eagles compilation.  I identified it as purchase-worthy because of the smooth case that had "Patent Pending" embossed on it.  These are some of the first CDs manufactured, when the jewel case was still a new invention.

I took the CD to the counter, paid and left the store.  After leaving, I snuck a peek at the CD and realized it was a common US pressing.  I was disappointed but unsurprised.  CDs can certainly migrate between cases, especially in a store that probably has a dozen of each title at any time.  I chalked it up as a buyer-beware failure on my part and moved on.  Later in the evening, I was looking at my whole day’s spoils and realized that the Eagles album was not in a smooth case.  I had been given a totally different CD instead of what I chose from the rack.

So I began debating if it was worth the effort to go back and demand the item I had chosen.  Would it still be there?  Would the staff just roll their eyes and say, "fuck off"?  Would I get the replacement and have it be no better than what I already had?  Was it worth the drive anyway?

I decided it would be worth the effort, and planned to go before driving back home on Monday.  My friends convinced me it would be better to try on Sunday because of workday traffic and were willing to sacrifice some of our day together to accomplish this.  So, with the store’s closing time quickly approaching, we set out for the store with the replacement.  We made it in the last 15 minutes.

I went to the rack and quickly found the same smooth case I had originally picked – they had simply put it back after I left.  I went to the counter and plead my case.  I had been rehearsing how to explain that I wanted this specific CD and not just any CD and had planned to try and be technical without being condescending.  At the most extreme, I would have to show them my Relative Waves website that explained the difference in CD masterings.  In reality, I was pretty awkward about the whole explanation, saying that I got a different CD, but it was the same, but it wasn’t the same.  Good job, Dave.  Way to explain it.

The guy at the counter said, no problem.  He went to the computer and scanned the old CD and my purchased CD, then retrieved the actual disc that was supposed to be in the case.  As he placed the CD in the case on the counter, he said, "there you go, Japanese pressing."  And at that point, I knew that he understood.  I didn’t need to say anything more than thank you.  And I left with my early pressing album.

Also on the list were some antique malls.  In my area, people seem to treat antique malls as consignment shops and as such, you can find people selling their personal CD collections (which technically could be antiques).  However, in this area, antique malls are filled with actual antiques.  Not of any benefit for CD hunting, but still a fun and interesting experience.  I did find some tiny décor items for the house, so it wasn’t all bad.

And finally, the thrift stores.  This is actually my second round of thrifting in Atlanta.  The first time was a long series of disappointments and this one was generally a shorter version of the first.  It just makes me more grateful that the thrifts in my area have some decent selection of CDs.  Maybe there are more collectors in Atlanta keeping the thrifts bare, who knows.

But the trip was not supposed to be about me and my hobbies anyway.  It was about the company and the experience.  In that respect, it was top-notch.  There’s plenty to be grateful for in spite of any success or lack of success in my hobbies.

Leaving Flickr

Posted by on January 3, 2020 No comments

Now that my blogs are on my own server, I’m going to have to content myself with much lower traffic.  That’s not really too much of a concern of mine.  But at the same time, there are some things that I do want to share, and I would hope they get some exposure.

I’m not a self-promoter.  I prefer to be discovered naturally, without any artificial boosts or bumps.  I guess it would help with credibility, like "oh, he’s only famous because he spammed Reddit every day for a year with links to dumb posts."  That’s like the opposite of what I want.  But really, I don’t want fame.  I just want to be helpful.

And on that topic, I have a few albums on Flickr that I consider helpful.  Some, based on views, might actually be helpful.  And I fear, when I move them here to this network, they won’t be discovered as easily or at all.  But, looking at it from another perspective, I am moving them here in case Flickr goes away completely, so there’s that threat as well.

Anyway, in the coming days, there’s going to be a new menu item for articles.  These are things that don’t really have the same meaning as blog posts, to be chronologically placed.  Maybe they’re like "sticky posts".  But these pages will have the content that was previously hosted on Flickr.  Specifically, some repair articles for keyboards I’ve owned.  The article format will be much better suited for the purpose than a photo album.

I’m going to have to figure out exactly how I will manage my CD Artwork collection as a series of pages.  I’ve looked for other places to host them and for one reason or another, it’s just never worked out.  And you know what they say, if you don’t like it, you’re free to do it yourself.  And I guess that’s the whole point of bringing my blog network in-house.

The Past, Present, And Future

Posted by on January 2, 2020 No comments

As I stated in a previous post, I am moving my blogs to my own server in 2020, and that day has come.  I managed to get everything set up and migrated all of the old posts in time.  So this is my last post here on WordPress.com.  I’ve had some followers over my nine years here and I won’t be offended if you don’t migrate with me.  I recognize the convenience and the nice community features a large site like WordPress has, and my little singular server isn’t going to have any of those niceties.  And to put a little extra emphasis on that, I set up my server to be essentially a closed system – no users, no comments.  So again, if you don’t visit, I won’t be hurt.  In fact, I won’t even really know.

Thanks for spending time with my words.  We all must be going to our new home now.  You can find more words in the future at https://anachostic.700cb.net.

Still Downsizing

Posted by on December 31, 2019 No comments

Or Resizing, whatever.  Trying to get rid of crap in my life that has no use.  Last week it was clothing.  I did an inventory of the clothes I had, and by others’ evaluation of the numbers, I had an excessive amount of clothes.  I had enough shirts to not wear the same thing twice for two months.

So that was the new project and the plan was to establish a baseline and institute a one-in/one-out policy to prevent that from happening again.  First thing I did to make sure I didn’t start sneaking in extra pieces was to buy new hangers.  Nice, wood shirt hangers and wood pants hangers.  I bought a 24-pack of shirt hangers and two 4-packs of pants hangers.

b1be03c7d5837d0af779ff3861c97215+ 21d8ef72437e51344010c35f90d975d2

This ensured that I had a finite amount of hanging implements.  Now I was limited to 24 shirts and 8 pants, which some would argue is still excessive.

Then I had to get ruthless.  I started pulling out my favorite shirts and putting them on wood hangers.  24 hangers went by pretty quickly.  I then started pulling out the remaining shirts and evaluating them against the selected ones.  Some got swapped out, a lot didn’t.  I kept a few extra shirts intending to take them on “a final ride” before disposal.  I filled out a large garbage bag that will be headed to charity soon and my closet actually has breathing room now.  I followed up with tee shirts and socks, realizing there’s some things I am never going to wear, and some is now obsolete because it doesn’t have a match with my reduced wardrobe.

Two things of note:  I think back (like it was forever ago) about picking my clothes for the day and paging through shirt after shirt until I eventually settle on one I wear all the time.  It’s nice to be free of that useless exercise.  The other is noticing just how long you can hold on to some things.  I had shirts that were years old.  Sometimes many years!  Part of my reassessment process is to start being more fresh.  If I’m wearing the same clothes for years, that probably could be keeping me in a certain pattern in some aspects of my life.

So now today, the bookshelf was the target of resizing.  I’ve collected a bunch of technical books and presentation materials over the years and kept telling myself, “I might need that someday.”  It’s been somewhere between 5 and 10 years and someday hasn’t come.  It’s time for these books to go.  Of course, there is the obsolescence factor as well with technical books, so I’m not missing much.  There’s kind of a psychological resistance to letting things go when you always remember the cost or the value of the object, disregarding the time for depreciation.  You look at it and always think “That seminar was worth $1,700”, even though that company is now out of business and you haven’t used those tools for a decade.  You need to remind yourself “that seminar is currently worth $0.00.”

Looking around my office, I see more and more things that will need re-evaluated.  My collection of wires: audio, video, computer, networking; my computer components (Do I really need a zip drive?  Do I need 3 keyboards and five mice?); even my computer DVDs, they could be ISO’d and stuck on a hard drive.  If I really needed a physical disc, I could burn it to a recordable DVD, then erase it when I’m done.

So much has been done and yet so far to go.

Random Roads

Posted by on December 31, 2019 No comments

I got to take a ride today.  It had been a little while since I had been out.  Last week I got the bike out and it made it to the driveway for about an hour and had to be put back for bad weather.

So this morning, I got the bike out and started riding before I really had a chance to second-guess myself.  I didn’t really have any destination in mind.  I had a quick thought about a road I always saw cars turning onto and I wondered why everyone wanted to take that road.  Where did it go?

So I went and found out what all the fuss was about.  It turned out to be a parallel road that goes to a neighboring town.  That’s good to know.  It’s good to have options when traffic or whatever happens.

Once in the neighboring town, I thought about what I would eat.  I had another memory that there was a pizza place across the road from the Boston Market that I had always ate at.  Whenever I would eat there, I would stare at this pizza place and wonder what it was like.  So, why not?  The pizza turned out to be pretty good and they had a good salad.  Not awesome, but nothing to stay away from.  While I was there, I could tell it was obviously a “family-run” business.  They had the kids in the back prepping food.  And as only young siblings would do, they were fighting.  Normal employees don’t tell each other to stop doing something and when asked why, state “because you suck at it!”

On the way back, I came across yet another road that I’d wondered where it went to.  It went parallel on the other side of the main route.  So I went out and back on either side of the main router between the cities.  Interesting.

As is evident in the picture, the clouds were pretty prevalent throughout the whole trip, so I got the bike back home and put it away.  When I was out, i didn’t see many bikes; maybe six.  Later that afternoon on the way to dinner, I saw just as many or more, but they were all battling the downpour we were all in.  And I was in my car.

Tonight, I was playing the keyboard and heading into the final segment of “Sunny Cathedral” when  a funny thought popped into my head that someone watching me play might comment, “why do you hate your keyboard so much?” I’m pretty rough on it.  I’ve broken 5 hammers so far:

image

But, I do like the power of playing hard.  When recording, you don’t capture everything, because you can’t hear the keys being smashed.  When playing softly, you don’t get the same tone.  Sure, there’s a time for playing softly, and I do utilize it in some songs.  But sometimes, the section calls for fff and then some.

It’s good to get back the strength and endurance I’d lost over a long period.  It wasn’t many months ago that I was saying I’d be happy if I could play “Interstate” and “Broken Legs” the whole way through on the RD-600 without getting exhausted.  That milestone has come and is far behind me now.

So my next goal, I guess, is some real composition again.  I have some pieces put together and at times, I can get them worked into a decent format.  As usual, I compose just a little beyond my ability so it gives me something to practice and grow into.

Interrupted

Posted by on December 31, 2019 No comments

Over the last week I ‘d been dealing with seemingly random shutdowns of my computer.  They would happen at odd times: 2:00 AM, 1:00 PM.  Always when I was never there, never when I was working on it.  I was wracking my brain, trying to figure out what would cause it.

The computer was recently disjoined from a domain, maybe a scheduled task blue screening the computer?  No, nothing in the event log about a Stop Error.  Nothing in the event log about anything, really.  Some USB device causing trouble (I suspected MagicJack)?  No.  Unplugging the USB devices made no difference.  Overheating? No.  Fans all work.  Bad RAM?  Well, maybe.  I mitigated the problem somewhat by changing the BIOS setting to power the computer back on if it was shut down unexpectedly.

My answer came on Saturday morning when I heard the computer reboot on its own at 4:30 in the morning.  I wasn’t going to jump out of bed and check on it, but it definitely became top priority for the day.  Later that morning, while I was on the computer, the power to the house blinked.  This happens often and the investment in UPS systems for all the computer equipment has paid back many times over.  All the UPS’s in the house raised their alerts, and my computer still shut off.

image

And then – because it had been caught in the act – the UPS started blinking its “Replace Battery” light.  Well, thank you…

So a quick trip to a battery shop, which I was expecting would end with “oh, we don’t have that in stock, we can order it, but since it’s Saturday we’ll have it in on Wednesday”, left me pretty impressed.  I went in and asked if they stocked UPS batteries.  They said they did, so I brought in the battery pack from my UPS and a dead, bulging battery from a cold spare UPS (not so much a useful spare, right?).  The salesman recognized the batteries right away, quoted me the price off the top of his head, and had them in stock.  Kudos to Battery USA for knowing their stuff.

Ten minutes and $50 later, I was out the door with brand new batteries and prospects of a smooth-running computer.  Haven’t had a glitch since.  $50 in batteries beats out buying a new $250 UPS by… about $200 or so.

Welcome To The Jungle

Posted by on December 31, 2019 No comments

I have recently moved my web hosting and email to a new dedicated server on GoDaddy.  I’m rather pleased by this because it will allow me complete freedom to do whatever I want with the server, set up as many websites as I want, install any software, and resell hosting services.

But with great power comes great amounts of bullshit.  With my old hosting account, I had the benefit of some decent anti-spam measures.  So now that my mail is off that server, I ‘m now exposed to more spam.  I’m trying to take it with a good attitude, because some of it is clever and some is just downright retarded.

Case in point, the following email received today:

capture

Edgardo from the USPS is emailing me from his school email account to tell me, in a poorly-constructed sentence, that they couldn’t deliver a package I sent.  He was nice enough to attach a shipment label in a zip file for me to print and collect at their office, wherever that office is.

Example #2:

image

This one is obvious.  You mouse over any link and the address it directs you to is not facebook.com, but some other address where you will get infected.  The best part of the email is that it is a notification for a facebook message posted on December 6, but the email notification was sent 5 hours early, on December 5.  Now that’s advanced technology, like they have in Nigeria, which happens to be in a time zone +6 hours away.  And we just happen to be on Daylight Savings Time here.  Nah, no coincidence.
