Wesley's Tool-Box

The first time I traveled to United States since I left North America in the mid 1990's was back in 2006. South Korea was not on the Visa Waiver Program (VWP) at the time. So I, like most of the Korean nationals, first needed to come to the U.S. Embassy in Seoul to submit an application for a B1/B2 non-immigrant (visitor) visa and go through an interview. I wrote about the entire experience in detail, including the long lines.

The resulting visa has served me well for the past decade, even after South Korea was admitted into the VWP on November 17, 2008. This was because valid visa holders don't need to get the ESTA (Electronic System for Travel Authorization) clearance. But it ultimately expired and because I have an upcoming business trip to the States, it was time to renew it.


There have been considerable changes in preparation. In 2006, the "electronic" aspect was that the application forms (DS-156 & 157) were downloadable and that the interview could be scheduled online. As I write this, the form was changed to DS-160 and the entirety of it could be entered online (including the photo), needing only a simple "confirmation page" to bring in instead of the entire form. Also, payment process became simpler. There are no separate interview fee and processing fee anymore - it's all included in the processing fee now. And depositing the fee online to a uniquely generated account number (doubling as a "proof of payment") became possible in addition to the traditional option of having to visit a bank branch. However, the price has risen from $112 total to $160 for the B1/B2 visa.

Once the payment was made and the form was filled, the next step was to schedule an appointment for the interview. But since I was renewing the visa, I was apparently eligible for the Interview Waiver Program (IWP). Thanks to this, I was allowed to use the drop-box service at the interview reservation page after answering several questions to confirm my IWP eligibility.


Drop-box service basically means I can "drop off" the necessary documents (passport, confirmation page, etc.) at a branch office of a contracted courier (Ilyang Logis, in this case) and it would be shipped to the embassy for processing at no extra cost. There was one such office at the small town I live in (Naju), so I decided to pay a visit. But as you can see here, it was expectedly small and the staff had no idea that such service existed. Apparently, I must have been the first person to try this at the place. After contacting the head office and getting the instructions, the staff collected the documents I brought and promised me that they would be sent soon. They had to be put into a special packaging that had to come from the head office, so in reality it took about three business days instead of going out the same day.

It's now been one full year since I started wearing Apple Watch Sport and now is a good time to give you an update. I have been wearing it all the time except when it needs to be charged, so it has been through a lot. Daily showers and occasional swimming sessions may have caused a bit of degradation on the left edge of the screen, and an encounter with a rough surface left the glass with noticeable scratch lines. Despite all this, it's holding up well and functioning normally. I'll probably send the device in for replacement using AppleCare+ after I buy the next version, though.

In terms of battery life, it has consistently delivered at least 24 hours of use for me, except during early watchOS 2.0 betas. So I'm now accustomed to about 22 hours of use (with about 10 to 30% left as I take it off) and 2 hours of charging. The only times I wish the battery life was longer is when I do long-distance travelling, where the active time might stretch beyond 30 hours.

As for its uses, I've settled on the watch mainly being a quick notification-response device and a fitness tracker. Those two functions currently work fairly well. Meanwhile, the native app support with watchOS 2 has been hampered with the relatively slow performance. It often makes me want to reach for my iPhone instead of loading the relevant app on the watch. This needs to be addressed in the near future if Apple Watch is to be taken seriously beyond being an "accessory."

Now, the fitness tracker part of the watch was something I was looking forward to when I bought it. I have lost weight through exercise before, but lack of reminders once the goal was reached resulted in regaining some of that weight after a few months. So I decided to make good use of Apple Watch to keep me stay fit. I made sure to reach the daily Move goal every day, which had been set to 450 kcal after the first month. Missing this goal only a couple of times, I was able to earn the "365" badge you see above two days ago. Let's see the activity and weight trends in detail.


Why did I choose the 450 kcal mark? This is generally about 200 kcal more than I would normally burn through a normal day. 50 minutes of walking or 20 minutes of jogging can fill that in - these activities can easily blend into the daily routine and also conveniently make me reach the 30-minute Exercise goal in the process. Basically, I can get the bare minimum amount of exercise that Apple Watch recommends via its three-ring system with that setting. The graph evidently shows that I don't actively seek out to go beyond this goal unless something else is going on, like when I'm traveling. Some of the big spikes correlate to my overseas trips - New Zealand in May (2015), UK in July, and Japan in September, to name a few.

As a side note, the data for the resting calories starts on July 9 because this is when watchOS 2.0 beta 3 came out and made Apple Watch start recording this data on iPhone's Health database. Before that, the data resided only within the Activity app, likely because it was rudimentary and static, not to mention less accurate - it was about 40 to 50% more than expected. Since the update, the resting calories data is recorded in real time and seems to be more in line with the mainstream calculations.

Interestingly, I noticed that just reaching the Move and Exercise goals wasn't doing a particularly good job of shedding the weight in the early months. I did have a weight scale and occasionally checked my weight with it, but it hovered between 83 and 84kg without any upward or downward trend during that time. Besides, I never got around to recording the data anyway. The only data point during the period was from the annual check-up at my workplace. I decided to do something about it and got myself a so-called "smart scale" with Bluetooth connectivity in August.
