The bottom line is that certificate based security is only as trustworthy as the companies responsible for the certificates. Companies generally, large companies in particular, and large security companies especially, are ultimately vulnerable to the whims of government actors. Look at how effective the NSA has been at undermining security standards without even bothering with bringing the coercive power of the government to bear.

I'm not saying that I don't use HTTPS everywhere possible, but I understand that it's like putting a band aid on a sucking chest wound. It addresses a handful of problems, but leaves the underlying issue untreated. I don't know what the solution is, but I'm absolutely sure it will involve a complete paradigm shift in how we handle trust relationships.

As 40Hz already knows, I bought a new Schecter 5 string bass about the time I stopped posting to this thread last year. With a budget of only $400, I was actually planning to buy something used, which really sucks for a lefty. Fortunately for me, Schecter had discontinued this particular model, and I managed to get one literally a couple days before they became pretty much impossible to find. As a bonus, the new price was about what I'd probably get selling it used, so it was practically a zero risk purchase.

I fell in love with it the first time I played it, and I love it just as much now. It's everything I expected from a Schecterat that price (it normally sold for around $650 - $700), except for one annoyance. I say annoyance, but had I payed full price, or if I had to pay someone to fix the 1 design flaw I discovered, I'd be pretty pissed. Instead, I'm mildly annoyed with them, and more annoyed with myself for not tracking the issue down sooner.

To make a long story short (mark that on your calendar), Schecter put passive EMG pickups in the bass, which is fine, but then they paired them with the wrong EMG EQ module. EMG sells 2 OEM specific EQ stacks, one for active pickups (which most of theirs are) and another for passive pickups. Not being an OEM, I can't be sure, but I'm betting the active pickup (200k input impedance) version is cheaper than the passive (1M input impedance) one, because it doesn't need to include a buffer (which active pickups have) to avoid impedance loading the pickups. Even if they're the same price, generally, I know Schecter sells a bunch of basses with active pickups, so it would probably have increased the cost moderately to buy a separate (and smaller) batch of high impedance tone stacks).

Whatever their reasons, here's what the difference between 1M and 200k looks like on a frequency plot. They're different pickups, but the effect is fundamentally the same. There are actually 3 different impedance options listed, because it's for an Audere preamp with a variable impedance option. However, the Low Z and Mid Z plots are for the exact impedances for the active and passive pickup EQ modules, respectively. Not to mention that 1M is what every standard onboard preamp uses, and for the exact same reason.

Fortunately, it turns out Bartolini sells a reasonably priced buffer/preamp circuit, so I can fix it without buying an entire preamp/EQ unit. At this point, I can't say I even know what either the pickups or EQ sound like when wired properly, so it would be wasteful to replace them without finding out - especially at nearly half the original cost of the bass.

Thread necro powers, activate, form of...Graduate Thesis Student!

Vurbal,

I am interested to see how your quest to organize your thoughts has turned out as it seems you and I share a similar mind. I was wondering what you found and what you see as the strengths in such a product. I am not officially underway on my thesis in my Master of Science in Information Assurance course, with the ultimate goal being a Doctorate of Science in Information Systems to follow. As such, I am looking for a way to keep all of these random ideas and thoughts that populate in the tangled mess I call my brain somewhat organized. Have you had any luck?

I don't have time right this moment,  but I'll try to answer this with enough detail to be useful. The short version is yes, I have had some luck, but with quite a few caveats.

If I haven't posted again before tomorrow afternoon, shoot me another PM because it probably means I've forgotten entirely.

Congratulations.   I have pretty good experience messing with MBR.  But with W8 they changed to this UEFI and GPT jazz.  I understand it had to be changed to accommodate huge storage.  But I don't dare to do anything without a lot of reading in preparation and expendable machines to experiment with.  :)

Plus a lot of bootable utilities that worked for sure on MBR are now suspect.  Can't take anything as a given. 



As I learned last year, Dell's recovery process was already suspect on MBR systems - and that's being generous. Throw in those additional variables and it's clearly a train wreck waiting to happen - at least for the average user.
