Windows XP Restore Points

Windows XP’s restore points have saved me loads of time in troubleshooting problems with my Dad’s computer. Rolled the thing back to when I last had it and it’s fine… I’m thinking the problem is with an old version of Printmaster Deluxe which my Dad installed. (It is old enough that it didn’t show in Add / Remove Programs.)

I’m thinking that it overwrote some Windows files somehow, and Windows File Protection, for some reason, didn’t do its thing. That somehow messed up the machine, it started running slow, etc. I’ll test this tomorrow (or whenever I return the machine) by setting a restore point, installing the questionable app, inspecting things, then rolling back to the previous point if needed.

Car!

Yay, I have a car again… The inside door panel still needs to be replaced, but that’ll get taken care of sometime next week. Also, the place rotated the tires for me, so I don’t need to have that done for a while.

Oh, and I seem to have resolved the internet problems by switching the APs back to Channel 1 from 11. I had changed them to 11 a week and a half ago or so, and since then the signal had been about 50% everywhere. Back on 1 and it’s nicely full.

More car troubles… Of all different kinds…


Pontiac G6 which I have to drive for a day. (At least…)

Okay, so as mentioned before, someone had hit my car right after having it repaired and I had to take it back in. Due to a convoluted bunch of things happening today, I now have the Pontiac G6 seen above to drive to work tomorrow.

Although I didn’t mention it before, there was one more problem with my vehicle after I got it back from being repaired. That is, the door lock on the passenger side wasn’t working quite right, and it couldn’t be manually unlocked. This isn’t a huge problem, and when I took the vehicle in to have the bumper repaired I mentioned it to the person at the shop, and he said he’d have that sorted out.

Well, fast forward to today. At about 4:00pm I walked up to Cass Collision to pick up my vehicle, and it was waiting for me, looking great. I picked it up, and drove the mile (or so) home. After I got in the garage I noticed a couple of problems. It appeared that whoever had taken apart the door to fix the aforementioned lock issue nicked up both the door panel and the handle itself. There was a small screw which holds part of the bumper trim (the piece which needed to be replaced) in place which was missing, and one of the screws / mounting pieces for the cargo net in the trunk weren’t reinstalled.

So, I drove back to the shop and talked with the manager Andrew who started to take care of these all right away. He ordered a new door panel and handle and the missing screws so that everything could get sorted out. While I wasn’t too happy with the problems existing, I feel pretty comfortable that the problems were going to get sorted out, so I left and headed back home.

While driving home I noticed a rather curious sound coming from the rear wheels, but I chalked it up to a rock in the tire. However, when I got home I noticed some scuffing on the wheel right next to where the vehicle was hit, and that led me to thinking that the wheel might be slightly bent, or some other similar problem. (This scuffing wasn’t initially visible to me when the damage first occurred, because the wheel was dirty and the paint on the wheel is practically the same color as the underlying aluminum.) I immediately called up to the shop and we arranged for me to head back there, and they’d take a listen for the noise.

Andrew and I hopped in my vehicle and we drove the 22 Mile / Schoenherr / 23 Mile / Hayes loop back to their shop and both heard the noise. So, it was agreed that the shop would order a new wheel and after it was installed they would have their mechanic look at it and ensure that nothing else was off.

Then, things got really interesting. After dropping Andrew back off at the shop, as I went to pull out of the parking lot he and another one of the employees flagged me down and ran up, saying that my rear tire (on the driver’s side) was flat. I pulled the vehicle into one of their service bays, and looking at it, it was an absolute, complete, dead flat. The vehicle was jacked up, and Andrew started looking at the wheel. After seeing a piece of metal in it, Andrew grabbed a pair of pliers and removed it. For some reason there was half of a bearing jacked completely embedded in my tire!

After discussing it a bit, we figured that the noise was probably being caused by the piece of metal stuck in the tire which broke off, eventually causing the flat. It seems the shop had received a load of write-offs for assessment earlier in the day, and it’s thought that some bits fell off of one of the vehicles and ended up somewhere where my vehicle was moved past.

So here it is, 5:30pm, at the shop, with a flat tire from something at their facility, a damaged wheel, a marred door panel, and some a missing screw in the trunk. We could have just put the emergency spare on the vehicle to get me to work the next day, but I was a bit hesitant to do that. So, Andrew went and made a quick phone call and arranged for a rental car for me to drive tonight / tomorrow. We then got in his vehicle and he drove me to the Enterprise rental facility over at Hall (M-59) and Heydenrich where we picked up the vehicle seen above for me to drive. He’s going to get the tire bits sorted out, then give me a call and we’ll take care of the return of everything.

While I would think that in this situation I’d be a bit frustrated, I can’t really say that I am. Sure, I don’t have my car and the repair shop made some mistakes, but they sure seem to be taking care of them. I’ve got a vehicle to drive and I’m fairly confidant that the problems are being taken care of.

Now, if only my internet access would stay up. :\

Lightsticks In The Toilet Fallout / Digg Effect

So, earlier today I submitted my Lightsticks In The Toilet LJ Post and photo album (photo gallery retired) to the Make Blog. I had also submitted it to Digg sometime last night.

Well, it has been posted on the Make Blog, and the Digg link has really taken off. With a total of 5 fastcgi processes for myself (nuxx.net, et al) the box is sitting at a load of ~5 to ~10, and is handing out loads of data. Feel free to watch the bandwidth consumption here.

This is interesting. I’ve only had to deal with tremendous bandwidth load before (eg: hosting the SG videos, or original seed for Katrina photos), not something that actually loads the box.

I just moved the photos to nine per page (3×3) to cut down on the impact of each page load. We’ll see what happens, I guess…

Old Hardware…

I’ve got a bunch of hardware here that I just can’t bring myself to throw out. For example, a Digi AccelePort C1 (with a REAL 16C650) which I had previously used with a 3Com ImpactIQ for ISDN network access from 1997 through 2000. There is also the first computer I bought, a Pentium 90 which I’d paid almost $3k for, with 17″ monitor. A real, made in the USA 3Com Sportster 56k x2 modem from the time before the v.34 standard was formalized, which had been subsequently flashed to v.34. Some great-for-wardriving Pentium II 300 laptops, etc.

Lightsticks In The Toilet

Tonight while going through a few old boxes in the basement I came across red and green lightsticks, still in the wrappers. So, I opened them and activated them. After playing around with them for a little while I decided to do something I played with when I was much younger, except this time I decided to take some pictures of it.

What did I do? I cut open the light sticks and poured them in the toilet, watching the slowly changing, swirling psychedelic glow emanating from my toilet. Unfortunately these toilets aren’t that great for it, as most of the oily phenyl oxalate ester and H2O2 ran down into the bottom of the toilet and out of view. Still, there were some interesting things to see.

More photos of this all are available here in the Lightsticks In The Toilet (photo gallery retired) album. Some of the better photos are:

· Toilet water with just the green cyalume lightstick compound in it.
· Red and green cyalume lightsticks setting on the toilet lid.
· Closer image of the toilet water containing cyalume lightstick compound.
· Lightstick compound swirling down the toilet as it is flushed.
· Photo 1 of red and green cyalume lightstick compound in toilet.
· Photo 2 of red and green cyalume lightstick compound in toilet.
· Photo 3 of red and green cyalume lightstick compound in toilet.
· Photo 4 of red and green cyalume lightstick compound in toilet.
· Glowing sink containing the remains of the cut open lightsticks.
· Lightsick remnants and cuts in the sink where I set them so they wouldn’t make a mess.

Data Destruction


Spool from a DLT IV cartridge cut open with a bandsaw.
(Click for more Data Destruction (photo gallery retired) photos…)

While cleaning out the basement (yes, the long-awaited get-rid-of-the-crap-you-don’t-use cleaning) I came across a bunch of old magnetic media which I wanted to render unreadable. I tried a few different methods, and I think that the best is the use of a band saw. As you can see above, DLT cartridges are easily disposed of by removing the spool from the housing and cutting half-way through them with a bandsaw. This turns the whole spool of magnetic ribbon into lengths no longer than ~6 inches. When a bunch of cut tapes are mixed in a box and then tossed like a salad they can be rendered nearly irrecoverable. I don’t think even the big agencies would be too anxious to try and recover data from that.

I also cut into hard drives, from edge of drive to spindle, and in one case cut away one corner of the whole drive. Having to dispose of some ZIP disks and DATs I also sliced into portions of these with the bandsaw before tossing them. ZIP disks would be cut to the hub of the platter, and DATs straight into the side of the tape bearing the full spool until reaching the hub.

I still have to figure out a good way to dispose of lots of both pressed and burned CDs. This too may employ the bandsaw, although a bonfire would work good as well.
