To the Instructables sysadmins

Happy Sysadmin day! Where would we be without you... out in the Big Blue Room, I suppose *shudder* So, have a good one!

Mac G3 password hacking?

I got a second-hand mac G3 for Christmas, from the sysadmin at my dad's office. Unfortunately, the sysadmin neglected to remove his accounts (and passwords), so as of yet it's impossible to get past the boot screen. Does anyone have any ideas about how I may crack the password or hack into the account... (changing the root password in single user mode doesn't work...) Oh, and by the way, it's running OS X of some sort, but since we can't log in, it's hard to know what cat it is. Help please!UPDATE:With the help of this site, we made an administrator account. We still don't know the master password, and there are a few untouchable files, but we can basically do whatever we want. The next challenge is to connect it to the internet...If you want to know how we got in, here's what we did:(1) we held down command (the propeller) and S as it booted --> this opened single-user mode, a command-line interface with root priveleges(2) instead of "rm"ing (removing), like the web site suggested, we "mv"ed (moved) /var/db/.AppleSetupDone to /var/db/.AppleSetupDone.old(3) we rebooted, and followed the instructions on the screenWhat did this do? It moved the file that told the computer that the computer was set up, so the computer ran the setup "wizard" like it was the first time the computer had ever been booted. After that, all we had to do was follow the instructions on the screen to set up an administrator (root) account. We also learned that the cat is panther, so we might be updating it to a newer version.Thanks for the help!

Dell indicator light? Don't throw it out!

I'm working on a project that will become an 'ible when it's done, and I need a little help from fellow sysadmins. If you come across a Dell-server indicator light, please don't throw it out! Send it to me instead! See, Dell servers all come with an indicator light on a cable (it's really just a blue LED connected to a 4 foot cable, and it ends with very thin barrel plug). The light is intended to be plugged into the server, then clipped to the side of the rack, so you can see if a server is off or on without looking at the back or front of it. Nobody ever uses the light as far as I can tell. Where I work, we generally throw them out. I've been collecting all the ones that I come across for awhile now, and have only gotten together 16. The project I have in mind needs at least 60. You can think of sending them to me as recycling :) Thanks --Kyle

Internships at Instructables

Instructables needs interns, starting as soon as September! We're looking for smart, interesting people who can write well, are computer literate (sysadmin or coding skills are a definite plus, but not absolutely necessary), and are excited about sharing their knowledge with others. You'd do some site maintenance, community outreach, image manipulation, and some of the odds and ends necessary to make Instructables go. You'll also spend a few hours each week working on projects for your own Instructables, building things, taking pictures, and learning to use all of our fun tools! We'll pay you, too.You need to be creative, self-motivated, and learn quickly - things move fast in a start-up. We're particularly interested in people who are already involved with the site - a good set of well-written Instructables speaks louder than a long resume. If you're new to the site, show us something awesome that you've personally created. We want to know what you can do!Instructables is located in Alameda, CA (SF East Bay) with Squid Labs. Please send a resume, cover letter, and any other useful information to internships at instructables (dot com).

Create Scholarship Entry: Hearing Impaired

My project is designed to solve a personal problem. One I'm sure others struggle with. I am hard of hearing.My proposed project is for the iRobot to find me and tell me, via an LCD screen or similar visual, that the phone or doorbell is ringing. In order to keep the search path short, to start, in my house I'm thinking about using either virtual wall, which I can't afford, or a line down the hallway to the bed. When something is out of focus you can frequently stare at it until it comes into focus or you can ask someone what the sign says. With hearing loss you eventually realize you don't know you didn't hear something because people start yelling at you for ignoring them. Sound is fleeting. Usually only lasts a fraction of a second. I hear less that half of what most people hear. Without my hearing aids I can only hear the noisiest birds if they are about 20 feet or less from me. I can only hear my phone ring if I am within 15 feet of it and I have the volume all the way up. To talk on the phone, I have one that is relatively new and have the volume all the way up. Those 90db alarms, I need to be within 5 feet of them to hear them. The smoke alarm in the kitchen, I can hear it but it isn't going to wake me. A fire in the kitchen isn't going to trigger the alarm in the bedroom soon enough. It probably won't be loud enough to wake me, anyway.My house didn't have a doorbell when I moved in and I can't hear someone knock unless I have my hearing aids on and am within 10 feet of the door. After missing numerous UPS deliveries I installed a wireless doorbell and I carry the receiver, pager style, with me all day when I am expecting a delivery. And I have even missed UPS with that. If the water is running, the TV or radio is on, it is even more likely that I will not hear the phone or doorbell. If I'm in the bathroom even with the door open I don't have any idea what is happening on the other side of the doorway.A security system with cameras and sensors and a DVR would be ideal. But not in my budget. It might help me with my thieving neighbors.I have thought about getting a dog to help me but I have three rabbits and cannot afford another pet on my disability income. That would probably be a good solution. I own my own home, ok the bank owns it and lets me live here, but if I have to move into a rental most landlords do not allow pets. A robot would not be an issue.If I had a robot that could find me and let me know what is going on in my house it would be very useful. People do not wear hearing aids to bed. I don't usually wear my hearing aids at home to save on batteries. And because the feedback drives me crazy. I just turn the TV or radio up REALLY, REALLY LOUD. Sorry neighbors, it's not my intent to be annoying.I custom built the computer I am using. I have some experience programming simple robots such as the Parallax Boe-Bot. Most recently I built the miniPOV and mintyBoost from AdaFruit. I have 6 years experience as UNIX sysadmin and configuration management. I also have basic hardware and soldering experience. If I have enough time I would like to have it bring me the phone and have a microphone and speaker to talk to the person at the door. I would definitely like to add smoke and co2 detection but I noticed there are quite a few people taking that on and so I will leave that to the end. Maybe teach it to do a little dance, sing a little song, get down tonite. I could wrap it in mirrors, turn it into a floor disco ball. A different dance and sounds for each alert.A robot that could notify me of doorbell and phone events would make my life easier. I'd be inclined to sleep with it. If it could help clean up after the rabbits and ride herd on them I might worship it. Rosie the Robot, Rabbit Wrangler and goddess. If it could also keep me safe from intruders, fires, gas leaks and such. Heck I'll bear it's child! Shall I name it Proteus? or Alfred? Have you ever seen the movie Demon Seed? Classic.I took my time writing up my proposal to do some research and make sure I have the necessary skills and resources to accomplish this task. They warned us in the challenge. I also wanted to have something unique, although there can be many approaches to solving the same problem. If I do win one of the scholarships I will be interested in your suggestions about how to solve this project.
