My 2010 Halloween Costume: Ninja!!

I got the inspiration for this year’s Halloween costume from a parade in Modesto, California. I’ve dressed up as some silly stuff in previous years, so I wanted something cool this year. And there’s not much cooler than a ninja! Here I am showing off my ninja costume:

I tried to be authentic. Check out the details of my costume and shuriken:

The best part about this costume is that when kids ring our doorbell, I’ll go into stealth mode. They’ll never even notice as I silently drop to the ground behind them, pad up on split-toe tabi boots to drop candy in their bags, then fade into the shadows. I’m looking forward to trick-or-treaters this year. And I can even use the costume after Halloween to slip up behind spammers.

Thanks to the ninja parade for inspiring my ninja costume this year!

I did another sprint triathlon!

This morning I did a sprint triathlon (700 yard swim, 18 mile bike, 4 mile run) called the Tri for Real. On the plus side, I had an actual road bike this year. On the minus side, I broke all the rules of preparing for a triathlon: I only got four hours of sleep the night before, I worked out the day before, and I only trained for a short time after coming back from Kilimanjaro. So how did I do?

In 2009, I completed the same race in 2:03 (two hours and three minutes). In 2010, I finished the race in 1:53:02. I shaved ten minutes off my time from last year! Yay! Here I am afterwards:

After the Tri for Real sprint triathlon

Sweaty, but happy. Afterwards, my wife and I ate a tasty breakfast at Stacey’s Cafe in Pleasanton. Scott Adams, the creator of Dilbert, co-owns that restaurant, so I got to work out my geeky side along with my physical side today. πŸ™‚

Climbing Kilimanjaro

“Don’t think. Just walk.” — a fellow hiker.

Last week I returned from climbing Mt. Kilimanjaro in Tanzania, Africa. I’ll start with the bottom line: I made it to the top! πŸ™‚

Summit of Kilimanjaro with friends

That’s three of us at sunrise on the sixth day. We took the Machame route, which takes seven days. In theory, you could march right up the mountain, but you need time for your body to acclimate to the altitude, so after ascending for a couple days, you spend several days hiking around below the main summit getting used to the altitude.

We did something that 95% of people don’t do: we hiked up to the crater at the top of Kilimanjaro (18,000+ feet) and camped there overnight. There are some pros and cons to this approach. One big advantage is that you do the 6+ hour slog up to the summit during the day instead of starting at midnight. Hiking during the day is leagues better than at night, in my opinion. The other big advantage is that you get to explore the crater. For example, this was the view out the front of our tent:

Kilimanjaro glacier at 18,000+ feet

That glacier was just a five minute walk away, and then you could pet the glacier all you wanted. I gave this one a big hug:

There’s a disadvantage to camping in the crater though: you’re just below the summit, and so your body isn’t getting all the oxygen it wants. Most people hike to the top, stay for twenty minutes, and immediately descend. You’re spending most of a day at that altitude. We heard people throwing up in the morning, and later we recognized a couple people from Crater Camp going by us in a stretcher:

Kilimanjaro Express

That’s a normal stretcher with a single all-terrain wheel mounted underneath, and it helps get people down faster. Our guide jokingly called it the “Kilimanjaro Express.”

Some people reading this post might wonder, “Can I climb Kilimanjaro?” I read that about 50% of people make it to the summit. Kilimanjaro isn’t like rock-climbing; it’s like walking 5-7 hours a day, mostly uphill. If you’re reasonably fit, you’ve got a decent chance. I did a couple triathlons last year and did similar stamina training before the climb. That meant the Kilimanjaro hiking was more of a grind than grueling or arduous.

But it’s not really the walking that gets people–it’s the altitude. If you’re lucky, you’ll get a headache that Aleve can solve or possibly other mild symptoms of Acute Mountain Sickness (AMS). If you’re unlucky, you might get High Altitude Pulmonary Edema (HAPE) or High Altitude Cerebral Edema (HACE). One book I read said that for climbers of Mt. McKinley, which is about 1,000 feet higher, 3% of climbers experienced symptoms of HAPE, e.g. extreme shortness of breath, while 0.5% of climbers experienced symptoms of HACE, such as ataxia–think poor coordination or the inability to walk a straight line. As long as you’re aware of the symptoms and descend if things get bad, you should be fine. But you’ll want to read up on altitude illness if you decide to climb. In my experience, the guides on Kilimanjaro are very well-trained to spot HAPE and HACE. Fitness training doesn’t really help with AMS, HAPE, or HACE, so I was lucky to be in the “only got a mild headache” set of folks.

A better question is “Do I want to climb Kilimanjaro?” And that depends. Do you like camping and hiking? You’ll be camping without a shower for several days. You’ll face some real difficulties–several people told me it was the hardest thing they’d ever done. And it can be expensive (besides the airfare and the trip itself, you’ll probably end up spending hundreds of dollars on various gear). But it can be immensely rewarding to test yourself and see what your limits are. I think maybe we don’t do that enough sometimes. No matter what, it’s definitely an adventure.

By the way, the best shower I ever took was the first shower after Kilimanjaro. After a week on the mountain, I looked like this:

Kilimanjaro afterwards

During that first shower, I think the phone rang, someone knocked on the door, and at some point the power went out. I didn’t care. I just kept on showering. πŸ™‚

A few tips in case you decide to go:
– I’ve read lots of Kilimanjaro books, and the best one to start with is the book by Henry Stedman.
– I never walk with hiking poles, so I almost didn’t bring poles. Trust me: you should bring hiking poles. I definitely recommend the FlickLock or thumb lock poles over the “twist to unlock” poles. These poles worked very well for me. I’d opt for black handles if you can, because the gray handles got pretty grubby-looking by the end of seven days.
– Get good hiking boots and wear them all over the place for a month or two.
– Take care of your lips with SPF 15 or SPF 30 lip balm or Chap Stick. I used regular Chap Stick, which is SPF 4, but the sun is much stronger at higher altitudes. My lips were pretty sunburnt by the end of the hike.
– We flew into Kilimanjaro International Airport (JRO, but sometimes written as KIA) from Amsterdam on KLM. But a lot of people flew into Dar Es Salaam (DAR) via Dubai on Emirates. The people we talked to said that the Emirates flights were very nice.
– You may the word “Mzungu.” Our guide told us that it means “guest,” but a more literal translation would be “white person.” πŸ™‚ As far as I could tell, people are saying it with affection though.
– Hike at your own pace–ideally a slow, steady pace that you can maintain for hours. It’s Kilimanjaro, not KilimaNascar.
– Throw in a safari at Tarangire National Park, Ngorongoro Crater, or the Serengeti National Park. As long as you’re in Africa, why wouldn’t you want to see stuff like this?

African zebras

Or a sunset like this?

Climbing Mt. Kilimanjaro

I’m leaving Tuesday to try to climb Mount Kilimanjaro. If you want to show your support, please donate at charity:water. Anyone who wants to give is welcome. πŸ™‚

Mt. Kilimanjaro is the highest mountain in Africa, at 19,340 feet (5895 meters). It’s hard to climb Kilimanjaro, mainly because of the altitude. I’ll be completely without internet access for a few weeks. Don’t expect any blog comments or email replies for the first half of August–right now, I’m not even planning to bring my laptop. Not to worry, the webspam team itself will keep chugging away: reading spam reports, improving algorithms, and stopping spam.

I’ve been doing practice hikes with the three friends that I’m going with. Here’s a few camping tips that I’ve picked up:
– Headband lights sound silly, but they work really well. And if you get one with a red light, the bugs bother you less.
– But it’s important to know where your headband light is, or you’ll just be feeling around in the dark.
– Chocolate bars and pepperoni sticks make nice treats after a full day of hiking.
– OFF! (the insect repellent) is sticky.
– You can pick up Neutrogena sunblock at your local drug store. It works well, and is a lot less oily than some sunblock.

As you can tell, a lot of hiking/camping for me is focused on food and water, plus minimizing how oily/sticky I get. πŸ™‚

If you’ve got Kilimanjaro advice or a clean water story to share, I’d love to hear it. In the mean time, please donate to charity:water and let’s get more clean water to more people!

How to find start-up ideas

Chris Dixon had an interesting post a while ago about how to find start-up ideas. The advice boiled down to keeping a spreadsheet of ideas and talking to lots of smart people (entrepreneurs, potential customers, VCs, people at big companies). It’s good advice. Paul Graham also wrote in 2008 about startup ideas he’d like to fund.

Here’s another way to come up with startup ideas: walk around your house or apartment, and look for “hot spots.” A hotspot can be an area of high information density, clutter, stress, disorganization, or any place that has a suboptimal solution. Then think about a web or cloud solution to that hot spot. Let’s take a look at a few examples:

Music CDs -> iTunes, Amazon MP3 store, doubleTwist, MP3tunes, etc.
Bookshelf -> Amazon, Kindle, iBooks
Stereo system -> Sonos, Squeezebox, Rhapsody, Pandora,, Spotify, Grooveshark, MOG, Rdio, etc.
External hard drives -> Amazon Simple Storage Service (S3), Pogoplug

Okay, those all seem simple or obvious, right? Let’s go a little deeper. What would you do with this pile of business cards?

Pile of business cards -> CloudContacts

Here are a few more that come to mind:
Bank statements -> Mint
Photo Albums -> ScanCafe
Bathroom scale -> Withings
Pedometer -> Fitbit
Phone -> Google Voice, Twilio, Ribbit, Rebtel
Camera -> EyeFi
Stack of video games -> Steam, OnLive
DVD player -> Roku, Netflix Instant movies
Treadmill or Elliptical machine -> Nike+ shoe sensor, LoseIt! iPhone app, CardioTrainer app for Android, Fitbit
Pen -> Livescribe

All of these take a hotspot in your home and inject a cloud or web element to make life easier, more efficient or better. So what happens when you look at a pile of manuals, or receipts? Your alarm clock? Those “Learning Japanese” CDs? A stack of take-out menus? A stack of cookbooks? A hard drive full of MP3s that are disorganized? A hard drive that doesn’t have a back-up copy? An out-of-date programming book? A box full of videotapes? All those back issues of magazines? A blank wall, with no posters or other decoration? Stuff in your garage that you’ve been meaning to sell or give away? Your wallet?

Ideas are sitting all around where you live. If you have a small snag, irritation, or hotspot in your life, probably a lot of other people do too. You can make it easier to organize something (can you convert something physical to digital and store it in the cloud?). You can sell niche versions of a product (e.g. Threadless for T-shirts), you can let people make something that they couldn’t make before (CafePress for T-shirts, LuLu for books), you can pool people with similar interests (a blog like Craftzine, or a forum for book lovers or body builders), you can review products in a particular space, you can teach someone to do something. You can become a well-known expert in something and then sell your time or expertise as a consultant. You can make a free version of something useful or fun, then sell more features or consult on more involved cases. You can do meta versions of lots of these, e.g. Etsy is a marketplace for people who like to buy and sell custom crafted objects.

I’ll stop with a story. I have a friend at Google who is really good at noticing things that annoy him. While walking from his car to his desk in the morning, he can easily find six things that irritate him because they should be improved. I’m not recommending that you make yourself more irritable, but I am saying that if you notice all the times you run across something that can be improved, those are opportunities. And I think one of the easy methods of spotting start-up ideas is looking around where you live and how you spend your time. Find the hotspots in your own life and you might identify some great products or services to build.
