Arkanoid Artwork

About a Decade ago, I build a handful of cocktail arcade cabinets with my family. Cocktail arcade cabinets are arcade cabinets where the screen faces up through a table top, and the players sit down on either side of it. We build them all from scratch with nicer materials and build quality than actual cocktail arcade cabinets.

Pictured above is an unfinished (un-stained) Ms. Pac Man cabinet. Once they were completed, we each chose different games to put in our respective cabinet. I chose to put Arkanoid and Arkanoid: Revenge of Doh. Arkanoid is a classic break-out game made by Taito in the 80’s. It’s a bit more fun than just plain-old break-out since it has power-ups, bosses, and some semblance of a storyline.

In any case, one thing that was never completed to my satisfaction was the top. I printed out some power-up keys that were found on many Arkanoid cabinets, but never thought it looked very good. I’d thought about removing the artwork all together as well. But then I decided that it would be cool to print out an actual cocktail overlay as was common in the 80’s.

Many games, such as Pac-Man, Galaga, etc. had overlays that covered the entire top of the cocktail cabinet. I’d never found an Arkanoid cabinet with nice artwork, so I whipped this together. The goal was to look retro, incorporate the actual logos, and power-up information. (Click the image to enlarge) I’d say that I’m pretty happy with the result. The next step will be to print and cutout this design. It measures at 22″ x 32″, so It will need to be printed on a plotter, then laminated to protect it. I will post pictures of the finished result when its ready.

Password Reset

A little bit ago, I was confronted with a problem whose solution I think is worth sharing. My mother-in-law forgot what password she had put on her new (used) MacBook. Normally this isn’t an issue because you can always pop-in the installer disc and reset the password. Unfortunately, there was nary an installer disc to be found.

Fortunately, there is a trick for just such an occasion.

First of all, make sure you know your short username. This is the name you see on your home folder in the finder.

Once that is retrieved, boot into single user mode. This is accomplished by holding the command key and “s” while booting. Single user mode puts the computer into a command line interface as the “root” user, or administrator that can make any changes – no questions asked.

But first, we have to make the filesystem writeable, since it is mounted in a read-only state initially. use the following command:

mount -uw /
Now that the filesystem is writeable, meaning that you can make changes to it, it is time to reset the password. Password retrieval is not feasible as it is encrypted, but you can overwrite it using a built in utility called passwd. passwd will create the new password and store it in the correct place with the proper encryption. To use it, simply type in the command followed by the short user name mentioned earlier.

passwd username
This will prompt you for a password which you will then need to type in twice for verification. Once you have done that, you can safely restart and use your new password! To restart, type the command:

shutdown -r now
Well, I hope this helps someone else out (and that it is only used for good purposes!).

Never Type This As Root

I was working on a shell script this morning to make my life easier on some trivial task. The last few lines looked a little like this.

somedir=/mnt/tmp mv $somedir/*.txt ~ rm -rf $somdir/*
Obviously I meant to remove all the files in the directory, however a typo in the variable name led to the deletion of /. I caught it before it got to the home folder, but bin and dev were gone resulting in a broken system that needed to be reinstalled.

Never delete * as root unless you are sure you know what you are doing….
