DeLorme InReach SE

I recently bought a satellite communicator, the DeLorme InReach SE. It can send an SOS, and it’s a two-way communicator, so rescue personnel can tell you they’ve actually received your message. Of course, you can also use it to text … Continue reading

Transcendence

I watched a pre-screening of the movie “Transcendence” today. Some cliches, like wildly flashing and scrolling consoles and computer-generated voices, as well as the somewhat rapid end aside, the movie was well-made and thought-provoking. Below are some thoughts that occurred … Continue reading

OneNote for Mac, One Caveat

In my last post, I claimed that OneNote for Mac didn’t exist. That’s actually not true. My friend Chris informed me that about two weeks ago, Microsoft released OneNote for Mac. That still doesn’t help me, because OneNote for Mac … Continue reading

Goodbye Old Work Laptop, Hello New Work Laptop

At the end of last week, I turned in my old 3.5 year-old work laptop, my rugged, trusted Lenovo ThinkPad T410. When I started using it at work, I didn’t like it. I was using the MacBook Pro I had … Continue reading

Daily Yoga

For most of this year, I have done yoga every day. I still go to my class at the gym, but five to six times a week I do yoga at home using the Daily Yoga Android app. It’s fun, … Continue reading

Avalanche Class

At the beginning of the year, I attended an avalanche awareness class at Mt. Baker, organized by KAF Adventures. The class consisted of a three-hour theoretical introduction here in Seattle, followed by a whole day spent out in the snow … Continue reading

When Random Food Appears

Isn’t it weird how readily we eat food that randomly appears at work, even though we have no idea who put it there or where it came from? If I found food outside, I wouldn’t eat it. If food randomly … Continue reading

From Dijkstra to Me in Four Papers

I haven’t written in a while. I at least wanted to write about going snowshoeing while attending an avalanche class. I’ll get to it some day. Today I found a website that computes distance between computer scientists. Kind of like … Continue reading

Summited Mt. St. Helens

My wild hair and I summited Mt. St. Helens today. It was a hard hike, but it was worth it. I climbed about 4500 ft (1,372 m) — that’s over 340 floors in a building! — and hiked 5 miles … Continue reading

Sleep Time

Mostly out of curiosity, I downloaded the Sleep Time app for Android yesterday. It’s an alarm clock that uses the accelerometer in the phone (which has to be placed on the mattress) to determine one’s sleep phase. Based on that … Continue reading

New Phone: Samsung Galaxy S4

In January 2011, I switched from my old Pam Treo 755p to an Android touch screen smartphone. At first I was skeptical about not having a keyboard, but boy, that was the right decision. I’d had the HTC EVO 4G … Continue reading

Healthiest On-Call Week

At work, every engineer has a pager. Every few weeks, depending on the team, an engineer is on-call and needs to respond quickly in case something breaks in the team’s products. The week ending today was, fortunately, very quiet. There … Continue reading

Snorkeling Pictures

I finally got the snorkeling pictures from last month developed. I think they call it “developing” — it’s been a while since I’ve used real film.

Pictures from Recent Journeys

I’ve done a fair amount of traveling again recently. It was exciting, and I got some much needed sun in the last two trips, but it’s good to be home again. For a while.

Practice Pays Off!

I reviewed the video recording of my first company-wide internal talk, which I gave twice together with one of my colleagues on October 23 and 25. Practice really pays off! I’ve never practiced this much for any talk, not even … Continue reading

XPS 8300 Shortcomings

So, now that I have disposed of my old Dimension 9200, I realize that the new (well, year-old?) XPS 8300 isn’t really all that expandable. The Dimension 9200 absolutely crushed it in that category. In the Dimension 9200, I could … Continue reading
