We've all had an "oh poopie" moment involving liquids: Time slows down, you watch as the glass tips over, its contents cascading (beautifully, in another context perhaps) over the rim and onto the table. The rivulets of beverage roll in a miniscule tidal wave across the surface, over the edge, and drip to the floor. All in the span of a few seconds.

The worst part is when there's a computer between the cup and the table. That's when an oops becomes a crisis.

What's the best thing to do when there's a spill on your laptop? Keep calm and carry on:

1. Don't panic.

First, know that your data is safe. Hard drives -- while not hermetically sealed -- are tightly put together. If you act quickly, you can prevent the liquid from getting to your hard disk, and damaging your valuable data. (I'll save the bad news for later.)

2. Turn off the computer.

Even before you run to get a towel, turn the computer off. If you can't shut it down normally (the keyboard won't respond for example), try pressing the power button for several seconds to force the computer to shut down. Unplug the laptop, and disconnect any cables and USB devices.

3. With the lid open, turn the computer upside down.

This prevents the liquid from getting too far into the computer. While the computer is upside down, remove the battery and set it aside.

4. Wipe up the liquid.

All joking aside: use toilet paper. Ounce for ounce, it's the most absorbent material you're likely to have handy. It's also thin, so it can reach down into crevices in and around your keyboard to soak up the liquid. This is especially important for sugary drinks like colas and juice: Sugars are sticky, and if they dry, you'll have a bigger problem.

Next: If you're prepared, you can take your computer apart to clean up any liquid inside.

We're not sure what someone has been putting in the water lately, but two separate vendors pinged us with case giveaways within minutes of each other. They're both using Twitter as the entry mechanism for the giveaways.

The first giveaway is from our buddies at Evernote, who want you to win one of ten Griffin Clarifi iPhone 3G cases every Friday in March. The Clarifi is pretty sweet, with a built-in closeup lens for taking snaps that are perfect for Evernote.To enter, all you need to do is send a Twitter message containing the #EvernoteClarifiGiveaway hash tag.

Not to be out-cased, RadTech is doing a giveaway of 5 NeoCases. These are sweet form-fitting sleeve cases for MacBooks, iBooks, and PowerBooks. How do you enter? Tweet @radtech with a clever statement including the word "Neocase", and you're entered. The drawing will be held Monday, March 9, 2008, and you'll be able to choose the size of NeoCase for your favorite Mac notebook.

Ars Technica reports that Apple will announce the latest additions to its list of vintage and obsolete machines on March 17. The list, initially reported through MacMerc, includes the following:

The "vintage" machines are ones where service parts are available to repair machines purchased in California due to existing statutes. This classification does not apply in the other 49 states.

• Xserve RAID
• Xserve (Slot Load)
• Xserve (Cluster Node)

The rest of the additions, to grace the "obsolete" list, include:

• PowerBook G4
• Power Mac G4 (Digital Audio)
• Power Mac G4 (Quicksilver)
• Macintosh Server G4 (Digital Audio)
• Macintosh Server G4 (Quicksilver)

These machines have all had good runs. I had a Quicksilver as my first post-college work computer and thought it was the greatest computer I've ever worked on the time - way, way back in the golden days of years gone by (aka 2002). These computers will now join their brethren in the Mac retirement home. But just because Apple classifies them as obsolete doesn't mean that you can't breathe new life into them.

Have fond memories of these machines? Share them in the comments!

Reader Sam K. (thanks!) noticed the fun on Twitter -- lots of folks are sharing their memories of the first Mac they bought/used with the #firstmac hash tag, and boy is it fun reading through them.

The responses are all over the place, from the old ][e (technically my first computer ever at school, though the first one I actually owned at home was a Tandy Color Computer my Dad bought from one of his coworkers) and //c up to the old iMacs and even a few people who can only claim iPod as the first Apple product they used. The first Mac I actually owned was much later than my first steps into BASIC -- when I needed a laptop a few years ago, I picked up a 12" Powerbook G4 and have been straight OS X ever since.

It's great to read this stuff, because you can see just how Apple has shaped people's lives. I was amazed to hear all of the emotion in the calls to Steve on our talkcast last week, but looking at something like this Twitter feed (to put your own memories in, just mark a tweet with the #firstmac tag somewhere in there) really shows you how dedicated Apple's products have made the company's customers. These people have all bought a Mac, whether it was a Mac SE (errrr, a Mac Classic?) or a MacBook Air, and never looked back since. Very cool.

And while we're at it, is it possible that you're on Twitter and haven't yet started following us? If not, jump in and do so now!

MacMod.com has announced their honorees for the best mods on Macs that they saw last year, and you can see all of the hacks and mods over at their site right now. Most of the mods are case modifications, like the very slick iPhone custom, and the "Xbox G4," as seen above, which is a Powerbook G4 modded into the case of an Xbox 360 (with working ring of light!).

I find it interesting that despite all of the slick case designs and gadget melds, the winner ends up being a software hack (well, it's actually more than a software hack, but still, you won't find any neon tubing in this mod, just a beige case): Leopard running on a PowerMac 8500. The mod itself ends up being a fine trip over the history of Apple's current software, its past machines, and all of the gooey chips and hardware inside. Very cool. Kudos to all the modders for their work -- we can't wait to see what 2009 brings to the mod community.

I am a huge fan of Gelaskins, and my iPhone has boasted one since I discovered a display at a small Toronto store back in May. Adhesive art for your iPhone, iPod, and Mac is a fantastic concept and a great way to express yourself beyond the typical hardware case.

Infectious is another site that offers art for laptops, cars, and more. They have recently launched a line for the iPhone. The site currently has 38 different pieces of art for the iPhone, and is currently on sale for $9.99. The Infectious stickers will fit both generations of iPhones.

You will get a large piece of art for the back of the phone, and a smaller one for the front that goes over the Home button. The artwork for the front of the iPhone is a fantastic feature that Gelaskins doesn't have, and one that I find very attractive. It makes it easy to spot your phone without having to flip it over to check the back or activate the screen to check the wallpaper.

Art for laptops is starts at $29.99 and will fit the Powerbook G4, iBook, MacBook, MacBook Pro and MacBook Air. The artwork is made on 3M vinyl material and can be easily removed to put on another piece.

Infectious is currently offering a deal for TUAW readers. Use discount code TuawRocks for 10% off from now until December 31.

FastMac announced a new line of Mac notebook chargers today. FastMac found a work around for Apple not licensing the MagSafe chargers. TruePower U-Charge allows you to charge your notebook's batteries externally. Note that this does not power the Mac, it only charges batteries.

This charger will charge iBook G3/G4 12", PowerBook, MacBook, and MacBook Pro batteries without skipping a beat. FastMac also has plans for a 14.4V charger that would charge batteries for the clamshell iBook, iBook G4 14", and Ti PowerBook 15".

The TruePower U-Charge comes in 2 different colors (black and white) to match your machine better. The prices for these chargers start at $69.95. You can purchase the U-Charge on the FastMac website.

TUAW reader and Flickr user sninesix posted this snapshot of the USB CPU fan he rigged up to cool his PowerBook. When the original fan died, sninesix found an old fan he had lying around, removed the wires and hacked a USB cable onto it.

He then removed laptop's keyboard and positioned the fan just above the CPU. With a USB keyboard connected, he was back in business. Well done! You can watch a video explanation here.

If you'd like to see your own rig featured here, simply upload photos into our group Flickr pool. Each Sunday we'll comb through the most recent entries and declare a "Rig of the Week!"

Brent Simmons, creator of the beloved NetNewsWire RSS app, is a talkative guy. We've chatted with him quite a few times about various Mac issues, and late last week he gave another interview to Shawn Blanc over at his website.

The interview is mostly about NetNewsWire-- the inspiration for its various features, and the development process Simmons goes through (he writes way more code than he ever uses, and calls himself an "anti-packrat"). There's also a picture of Simmons' workspace (above)-- he works on a Cinema display hooked up to a 17" iMac, with a 17" PowerBook around for PPC testing. He also has a HappyLite Sunshine Simulator right there-- I would think shining a light in my face every morning would wear me out, but he says it helps his Seattle existence, and if it gave us NNW (3.1 is on the way, we're told), I won't argue.

Always a good guy, that Simmons, except that he's a little indecisive-- he told us his favorite feature was the Attention Report, and now he says it's the spacebar. Make up your mind!

Want to install a game that makes you look as crazy as the poor woman in the video above? Look no further than Tilt Scream Pong, a game that utilizes both the Sudden Motion Sensor and the built in microphone in your Powerbook, iBook, MacBook or MacBook Pro. The basic game is really a solitaire pong game (like Breakout without the blocks), but the ball apparently moves faster and faster. Oh, and your paddle grows in size the more noise you make-- that's why this woman is screaming at her computer while flailing it around awkwardly.

Anyway, it seems a lot like Wii Sports in that you look like a dork while playing it, but it's actually fun to play. The game and source are available for free, and future plans hint at maybe eventually a two player game, or even two player network play. Check it out-- but do it behind closed doors or risk people thinking you're strange.

I haven't gotten into social music database Last.fm much, mostly (I'm ashamed to say) because I'm worried about some of my musical guilty pleasures being browsable by the Internet audience at large. Also, because I listen to my music in all kinds of ways, not just simply through iTunes.

One of those ways, of course, is my iPod, and if you've been trying to figure out how to get your iTunes listens scrobbled into Last.fm, worry no more: Scrobblepod is here to save the day. It's a go-between for iTunes and Last.fm, and allows you to sync your iPod listens up with Last.fm before your iTunes listens get entered, ensuring everything gets listed just fine. Now, people will be able to see that you've listened to Mamma Mia whether it's on your iPod or your iTunes install.

Of course, I still haven't seen a way to track the other way I listen to my music-- I keep all my actual music files on my Powerbook, and share them directly to my desktop through iTunes. That way, I have access to my music no matter where I take my laptop. Unfortunately, neither iTunes or Last.fm treats listens through shared libraries as if they were "real" plays, so no matter how many times I listen to that Timberlake Justice remix, it'll never show up on my "Recently Played" list, or in Last.fm.

But anyway, my problems are complicated. If all you want to do is track your iPod listens into Last.fm, Scrobblepod's got you covered.

We've seen laptops modded into picture frames before, but this one really caught our attention. Flickr user theducks used parts from two Pismos, some plastic and a bit of creativity to make this photo frame. It has a real cool mod look that we love. The only thing is that theducks is a little skimpy on the details (hint, hint, theducks).

Remember, you can add a shot of your Mac(s) to our Flickr pool at any time.

On November 16, an OnDeckTech 24x7 help desk technician received a call from a distraught PowerBook owner whose laptop had just been destroyed, trying to see if she could recover any of her data. Her 80GB 15-inch PowerBook, her two Maxtor external 300GB drives and her 160GB LaCie Porche drive had all been affected by the explosion of her new cable modem.

The details described by the technician, who posted both pictures and a detailed account of the explosion, reminds us that proximity--or a lack thereof--can be an important component in safeguarding your backup drives.

The data, fortunately, survived.

Thanks Andrew

DIYer Extensor posted pics of a self-built iCurve replacement over at flickr. Created to support his (or her, the page doesn't say) 15-inch Powerbook, the do-it-yourself-Curve is made from spare legos and a $7 Container Store wire shelf. The shelf is colorfully made, surprisingly attractive and looks sturdy enough to handle the weight of the Powerbook. We at TUAW love to see this kind of initiative and welcome your DIY Mac submissions. Drop us a line at our Tips form.

Most puppets scare me. Horrid little creatures, only coming alive when controlled by some being of perceived omnipotence manipulating every aspect of their pathetic little lives. But enough about my puppet paranoia, and on to this awesome hack. Some cunning (and brave! I'd never swing my notebook around like that!) soul has created a piece of digital artwork using the motion sensor built into his PowerBook. When he swings the machine, a little animated man on the screen reacts with realistic physics to the movement. Hooray for digital inertia!
