According to the tail end of http://en.wikipedia.org/wiki/Flash_memory, this article is ‘too technical’. Personally, I think it’s just the right amount of technical – any less technical and it wouldn’t get all of the ideas across. Chances are if you’re looking up flash memory specifically, you’re not scared by technical details. The wikipedia people shouldn’t scare away their more technical authors, IMHO.

Oh well. Nothing’s perfect.

you all will be pleased to know…

that my backup of my laptop completed with 0 errors.

Boy, do I feel sheepish..

1) The location to download WinZip 9 is in the FAQ.
2) My laptop seems to be backing up happily. Just to be sure, though, I will try to avoid using it until the backup completes.
3) I have got to do something about my negative attitude.

Tuesday, August 22nd, 2006

This day just gets better and better – I set the date forward on the wintel I’m using temporarily while my laptop is backing up, and it now will not run the WinZip eval version. So, I grab my winzip unlock code that I actually purchased from WinZip, and type it in.. and no dice. Oops, it was for V9.

Go to look for V9 on the web.. and it’s not there, except from people I wouldn’t download from on a bet. Winzip took it down to force people to buy V10, apparently.

Fight the urge to program my fax machine to send them 10,000 faxes saying ‘You Suck’.

Email their tech support. We’ll see what they say.

I gave up smoking many months ago, but this is one of those times when I really wish I had a cig.

My computer has gotten further along the backup process this time, and hasn’t crashed yet, but I’m chewing on my fingernails hoping that this situation continues. Currently, it’s estimating the job at about 4 hours. I have a somewhat slower but still acceptably fast Wintel desktop that I just fixed a few days ago that I can use instead.. although the focus on the monitor is nowhere near as good as the laptop – I wish that my super-hyper-excessive video card had a DVI port..

I may have to go computer-parts-shopping this afternoon. I’m really unhappy about this – I really didn’t need this today. The question is, do I deal with blurry video that will hurt my eyes, or do I go buy a fix?

I really think that LJ should allow Anonymous posters to include a psuedonym. Then I’d have some idea who to thank for finding those matching transformers for me…

Oh, dear…

Started backup, went for about 10 minutes and then system went down, *hard*. BSOD, kernal panic, yada yada dumping memory have a nice day.

So I don’t know what to think. Drive made similar clicking noise before crash. Upon reboot, system did not come up cleanly or usably. Turned power off at switch, turned back on, system seems normal now, trying another backup. Fingers crossed.

&(#% laptop hard drives..

Tuesday, August 22nd, 2006

Woke up and wandered in to start work for the day, and noted that my laptop’s hard drive was again making the ‘click-click-click’ that so many IDE hard drives make right before they find a new occupation as paperweights.

So, drop everything and configure samba on my 2T system so that I can back up my laptop to it. Start MS backup, cross my fingers that the 2G file limit fix on Samba actually works. (We’ll see, heh) Backup starts.

Ever watch a system back up over a 100 megabit link? At Epoch, we thought 100 megabits was blazingly fast, but guess what – we had systems with <40G disks! I wonder if anyone makes a gigabit PCMCIA card, and if so, what it might set me back.. I'm sure Google could answer that question, but I'm also sure that it won't be somewhere I can get it today. So stick it on the list of things to fix someday and leave backup running in the background.. Gigabit ethernet is pretty cool, though. It starts to make network-attached storage make sense even for moderately demanding tasks. I doubt if you could, you know, edit video over it - and in fact I don't have a clue what the performance is like on my LAN as I've only got one machine with a gig card (the 2T system aforementioned) I did order 3 gig cards today so I can put gig cards in all of my desktops. I'm starting to run low on Ethernet ports again.. might be time to get another switch. (I have a bad habit of just cascading 8 port switches to get wherever I want to go. Actually, it's worked so far...)

A tip for those of you who throw parties..

all of my experimenting with XLR matching transformers is not completely wasted. I did figure out this one really neat trick which has elimited the annoying hum and computer noise in my computer speakers.

(I should mention that my computer speakers are a pair of Mackie SRM450s with balanced inputs, and that most of this does not apply to you normal consumer-type people)

Take two XLR -> 1/4″ matching transformers (currently $15 at a guitar center near you), plug them into each other using a 1/4″ F-F adapter ($4), and add a XLR male-male to one of them ($8). Now what you have is a single-channel isolation transformer! Perfect for when you have to run the PA off four different wall sockets in order to get enough power to avoid opening breakers when you start feelin’ the bass. Add heatshrink to the transformer -> F-F -> transformer part, and you have a very useful generic adapter to keep in your adapter kit. Probably a good idea to keep two or three of them around.

Also, when running Mackies off unbalanced outputs that may have less than perfect grounds, a single isolation transformer plugged into a RCA-m->1/4″-f adapter (assuming you’re dealing with a RCA out) will improve the situation mightily. Very useful for ‘booth’ speakers when the power supply is noisy (and, at raves-^H^H^H^H^Hparties, they always are).

For those of you keeping track..

the ‘metal can’ RCA -> XLR adapter combined with a ‘official’ SPDIF cable reduced drasticly, but did not eliminate, the noise. I take this as a encouraging sign that what I have is in fact a signal degradation issue rather than a protocol incompatibility.

One thing that I really don’t understand is why a 25-ohm impedence mismatch is giving me this much trouble? Of course, the other thing is I’m driving a unbalanced signal with a common-mode ground into a balanced input, which may not be the best thing for signal integrity ever.

My hopes are currently on the AES-i to AES adapter, it seems to be *exactly* what should be needed.
