Disco Disc Burner App Public Beta for Mac OS X

Why is it that I always find myself ponying up the small amounts of cash it takes to purchase Mac shareware applications? Black fire and a disco ball? I gotta have it.

Today I fell victim to MacZot‘s current promotion (ends in 23 hours!) that saw me gobbling up the public beta of the Disco CD/DVD burning application for Mac OS X, and boy am I content with this lil 700KB number.

Firstly, the hype: when you purchase the beta at the silly-low price, you also get the opportunity to send a free license to someone else. So here goes – the first person to leave an intelligent comment gets the license! (I’ll need a real email address) This is a great marketing idea that see people not only using the beta of a terrifically designed piece of software, but also spreading the word to others so they can try it as well. Good show.

Disco Windows

Next, the features: Disco copies discs in two clicks. Say that ten times fast. Disco can span CDs and DVDs automagically. They call it Spandex, I call it dead sexy. This is extremely handy when backing up iPhoto or iTunes, trust me. Disco can burn VIDEO_TS folders by just dragging them onto the application, which makes it great for burning your DVD backups. Disco has realtime 3D interactive smoke that actually wafts up from the application as you burn discs. If you blow into your microphone, the smoke will dissipate, and if you move your cursor around the smoke itself, it reportedly moves accordingly – but I didn’t get to see this on the low-end test box. Disco has an amazingly simplistic interface that is very easy to follow as it prompts you at every step. Last, but certainly not the least in terms of features, and should really be in caps: Disco remembers every single burn and keeps a catalog of the burn sessions using what it calls “discography” so that you can easily do things like print labels, disk jackets, or simply keep handy for when you need that dot release or the pre-altered code that you can never find. Let Disco be your personal sherpa.

Disco runs very well for a beta application. I have yet to see it crash under Panther, Tiger, or even Leopard (WWDC or the 9a ADC build). Oh, and it worked fine in Tiger server as well. Unfortunately the test box is a 1st generation Mac Mini (PPC), so there was no “smoke” to speak of (anyone have screenshots?), so that will need to be tested later. I burned some mix audio CDs, a backup copy of the disk image for Disco public beta itself, an ISO image of Ubuntu Edgy Eft Beta, and a bunch of Gentoo releases, for good measure. No hiccups. I erased a very old scratched CDRW. I even inserted a scratched blank CDR to see what would happen… Well it wouldn’t burn correctly but Disco kept on keepin’ on – like some sort of Disco inferno – no bouncing beachballs of death here. And you call this a beta? I expected flames, not smoke. No crash and burn here.

In these screenshots you see the Disco app in full swing, from installation to a test burn, and a view of all the windows it provides. I really like the design of this app, and it was well worth the 15$ pricetag. If you’re new to MacZot, and need a referrer, feel free to use “blandname”. Now go write some optical media and dance around like a schoolgirl.

Oh and on the topic of Disco, and in the name of Halloween here’s a joke:

“Why didn’t the skeleton dance at the disco?”

“He had no body to dance with”

Where’s my Mac BIOS? (How to get into OpenFirmware Easily)

A lot of people these days appear to be under the impression that Macs have a BIOS, which is unfortunate because they actually have something much better – Macs have OpenFirmware. This is true for G4 Mac Minis, PowerBooks, iBooks, iMacs, eMacs, and Dual G5s… I could go on and on.
I got most of this info from experience and the Apple Developper Connection – if you’re not a member yet, sign up, it’s free.

You can get into OpenFirmware using this key sequence:

CMD-OPT-O-F

In detail, this means using two hands, holding “command”, “option” and “f” on the left and “o” with your right hand. Do this while booting your computer and you well hear two chimes. At the end of the chimes you will be greeted with an

On my G4 Mac Mini, for example, I can hold down the power button for roughly 10 seconds and I will hear the chimes – this should work for iMacs as well.

The OpenFirmware prompt that looks like this:

ok

0>

Congratulations, you’ve accessed your “BIOS” you switcher!

Now that we’ve passed this glorious milestone, we have some work to do. After all you came here for a reason right? (and not just to click on the ads, wink-wink nudge-nudge)

Some useful commands that save me time and time again, and enable reparation of the G4 Mac Mini:

Boot your Apple computer using the default boot device:

0 > mac-boot

Boot your Mac using the inserted CDROM at the yaboot directory for linux CDs:

0 > boot cd:,\install\yaboot

To eject a CDROM from your Mac:

0 > eject cd

If you have any other OpenFirmware tips to share, feel free to comment!

Ruby on Rails installed by default in Leopard

This is more of a teaser, but my dream has come true! Ruby on Rails is now installed by default on Apple Mac OS X 10.5 Beta (Leopard WWDC edition). Getting it up and running is really a snap.

Here’s the quick and dirty way to make a sample Rails environment and start the server.

Firstly, open the Terminal application. You know the scary black window with white text. Well actually it could even be white with black text – your mileage may vary (mine is black with green, for example).

Anyway, we’re wasting time – this is quick and dirty right? Otherwise I would be talking about chunky bacon.

In Terminal, type:

rails example

You’ll be met with a nice list of scrolling lines and when it’s done your “example” Rails application will have been initialised.

And that’s pretty well it!

Moving on, we want to see something tangible to prove to ourselves just how flippin’ impressive this really is, and why you knew when you saw that Apple Developper Connection article about Rails you knew good things were to come.

In Terminal, once more, sweating profusely now, we type:

cd example

ruby script/server

This runs the server for us. Once it has been set up, you can safely minimize the Terminal, and fire up Safari, Firefox, Camino, iCab, heck even Internet Explorer. We’re navigating ourselves to: 127.0.0.1:3000

Here’s what we find there (click the thumbnail to enlarge the screenshot):

Ruby on Rails 1.1.2 running on OS X Leopard

The nitty-gritty (no dirt band):

  • Ruby version – 1.8.4
  • RubyGems Version – 0.9.0
  • Rails version – 1.1.2
  • Active Record version – 1.14.2
  • Action Pack version – 1.12.1
  • Action Web Service version – 1.1.2
  • Action Mailer Version – 1.2.1
  • Active Support version – 1.3.1

It’s set up in a development environment by default (where you want it), using the sqlite3 database adapter (pretty typical).

Next time we’ll show you how to update these and run irb. Until then feel free to vote in our poll and support us!
