COVID-19: Part 4

I’ve now completed two weeks of working from home and it doesn’t feel like we’re at the halfway point yet. I’m seeing more and more empty shelves from people panic-buying and most of the world is still firmly on the path of exponentially increasing case counts.

But before I talk about any of that, let’s stop and be thankful for a few things:

  1. There is a huge shortage of things like bleach, toilet paper and hand sanitzer. But not only are the local stores not jacking up the prices, they’re keeping their normal sales! I saw a shelf that said “please limit yourself to 2 items” right next to a “Buy 1 Get 1” sign. Capitalism (or price gouging depending on your position) is rampant in the secondary markets, but it’s worth being thankful when you pay $2 for a loaf of bread instead of $200.
  2. As Tyla and I discussed the “crisis” and “emergency”, it dawned on me that I’m sitting on a couch, watching TV on a projector, enjoying a full stomach and a heated house.

That list could go on and on and I think it’s important to regularly enumerate your own reasons to be thankful, especially in this scenario when it’s so easy to focus on the negatives. Keep those reasons to be thankful in mind as we dive into the reality of the situation…

I’ll throw a very uneducated guess out and say that around Tuesday of next week, we’ll cross one million cases world wide (assuming we have enough test kits to prove that.) [UPDATE 3/20: Oops, when I made that estimate, I forgot that China’s cases aren’t growing at the same rate anymore. That means we’d cross 500k around Tuesday and it takes us until the end of the week to get to a million.] This is going to get worse before it gets better. The one page of data that I keep going back to is one compiled by Mark Handley: http://nrg.cs.ucl.ac.uk/mjh/covid19/ Every country is following the exact same growth rates, and, aside from China and South Korea, nobody looks to be anywhere near having this under control. Buckle up, we’re just getting started.

Locally, it’s hard to get a grasp on how seriously people are taking the social distancing. For example, this photo gallery shows a lot of empty scenes where normally there would be crowds of people. But if you drive around during the day, there are plenty of people on the roads.

As an elder at church, I’ve been in a lot of discussions about what to do with our services and how we can continue to minister to people as our ability to meet is restricted. For now we’re moving to having small devotions with individual families and doing more online. We’re also discussing how this will affect Easter because it feels very unlikely that we’ll be back to normal by April 12.

At home we’re continuing to make changes and lock it down. Tyla is starting to get into a routine doing her best to homeschool Elijah. What a blessing to have a wife who went to college to be a teacher! We’re also blessed to have a supportive school providing us with lots of materials.

Last fall we booked a vacation that we’ve been dreaming of for a long time: Disney Aulani. We spent a long time deciding if we were willing to spend that much on a vacation, but once we pulled the trigger, we were very excited for it. We were scheduled to leave a week from Saturday. Today I canceled the trip. While we are bummed to miss out on this, I’m very thankful that with the exception of the airline, we got 100% of our money back. And the airline changed their “sorry you bought a nonrefundable ticket” policy to give us a credit that can be used through the end of the year. So I’m trying to view it as “Hey, we have a gift card for a free flight to Hawaii and back!”

There are an infinite number of unanswerable questions about what the next couple months will look like. Personally I’m focusing on a lot of prayer, doing the best I can to make sure my family stays healthy both physically and mentally, and making sure we have food to eat. Time spent being anxious is time that would have been better spent praising God and trusting him to care for us.

Philippians 4:4-7 4 Rejoice in the Lord always. I will say it again: Rejoice! 5 Let your gentleness be evident to all. The Lord is near. 6 Do not be anxious about anything, but in every situation, by prayer and petition, with thanksgiving, present your requests to God. 7 And the peace of God, which transcends all understanding, will guard your hearts and your minds in Christ Jesus.

COVID-19: Part 3

There were a lot of questions when I wrote the previous post. There are even more now, but we do have some answers mixed in. Will schools close? Yep. All schools in the state are closed until late April and many across the country are closed too. Will more restrictions be put in place? Yep. No gatherings of more than 250 people and if you do have a gathering smaller than that, there are restrictions about how your employees must be trained, the minimum distance between people, etc.

Is this an overreaction? That’s one we don’t have an answer for. At this point I feel like if we’re going to do this, then let’s do it. Let’s learn everything we can to make ourselves smarter for next time, but for now? Let’s lock it down. We don’t know what the right answer is, but I’m guessing we’re less likely to regret shutting things down. All of these dates about how long things will be closed are fuzzy. We just need to see that exponential curve start to flatten.

Humans aren’t great at absorbing the implications of math, especially in two ways that make this a tough problem. First, it’s hard to grasp the speed of exponential growth. Delaying by even a single day can mean thousands of additional people get infected. And since it seems that most symptoms take around five days to appear, we’re much farther up that curve than the numbers show right now.

The second math complication is that humans don’t process probability well. It’s called “neglect of probability“. It’s either not going to happen or it’s definitely going to happen. Will millions of people die from this disease? Will we run out of food? Will toilet paper be the next BitCoin? None of these are 0% or 100%, but treating them as such leads to a lot of irrational behavior.

I’ve completed 7 days of working from home and Elijah will be off of school for six weeks. Sporting seasons are being canceled. Most public events are canceled. Travel is locked down to some other countries. And so we’re back to the most divisive question: too much or not enough?

We have quite a bit of data at our fingertips. We can compare countries who did too little with those who reacted quickly. There are a lot of good articles out there and I specifically recommend one from Tomas Pueyo and another from a group of researchers and foundations. The second one is especially eye opening because their conclusion on March 10 was that this area wasn’t doing enough to stop the spread yet. A lot more measures have been put in place since then so hopefully the predictions have improved, if they were correct to begin with.

On a more micro level, our family is chugging along. It’s a tough situation to plan for. Trips to Costco and Safeway both showed a lot of people stocking up. I’m not sure if there is some secret, delicious recipe for toilet paper, but if you don’t have it now, you’re not going to find it. We’re well-stocked here (including ammo so don’t think about it… kidding… sort of.)

I’m blessed to have a job that allows me to work from home. Our team is adjusting well and I think we’re getting into a productive groove. My only real hangup is that this desk that I built in 2013 has never been the most comfortable thing. I can’t figure out exactly what it is, but a day at this desk leaves my back feeling sore. Since we’re going to have such a long spell of working from home, I ordered an electric base for a standup desk. I use mine a lot at work and it has always felt like too much of a luxury for home, but this situation pushed me over the edge. I saved some money by purchasing only the base. I’ll start with a simple plywood top but eventually I want to put a beautiful walnut top on it.

So we continue to chug along a day at a time. It’s amazing how many conversations I have about this single topic. I find myself wishing for a day where I don’t have to think about it. My hope is that once we get to “peak lockdown”, we’ll hit “peak panic” too and just hang tight for a while.

Psalm 91
1 Whoever dwells in the shelter of the Most High
    will rest in the shadow of the Almighty.
2 I will say of the Lord, “He is my refuge and my fortress,
    my God, in whom I trust.”

COVID-19: Part 2

On Friday I woke up to the news that someone in our division had tested positive. The company notified everyone who was likely to have been in close proximity to him. It was in another building so it’s highly unlikely that I crossed paths with him, but it does make the “everyone work from home” recommendation seem like more of an obvious good move.

The first couple days of working from home were less productive than normal, but I think our team is getting settled in. I was asked to collect some best practices and set expectations about how we will interact and stay in our highly-collaborative mode even though we’re separated. Thankfully, collaboration tools have gotten a lot better in recent years, and while there are a lot of things I’d change about Microsoft Teams, it really is an excellent service.

Over the weekend, life continued to be pretty normal. We met up with Tyla’s family on Saturday to celebrate Logan’s birthday and then we went to Pizza Coop for dinner. I wasn’t sure what to expect there, but it felt like a very normal Saturday evening crowd. Church was well-attended on Sunday as well. The grocery stores are well-stocked, and other than news stories and less traffic than normal, there’s very little to indicate that anything odd is going on.

But it’s that normalcy that feels the strangest. Major snowstorms and power outages have a visible component and it’s easy for me to understand what I can do to help keep my family safe. But in this case, it’s a silent virus floating around. Could we do everything as normal and not be affected? Have we already come in contact with it and not caught it? Are we on the brink of exponential growth in the infection rate? None of these things are knowable or measurable. Life goes on except that every time someone coughs, heads snap in their direction and people scoot away.

It remains to be seen whether our current efforts will be effective in stopping the spread of COVID-19, but I’m also interested to see what effect our improved hygiene has on standard illnesses like colds and the flu. Will those numbers be noticeably lower because we’re all washing our hands more often and staying home even when we have a little cough? I’d like to think that improved hygiene will be something we all take away from this, but the reality is that we’ll probably revert to our old ways a few months after this scare is over and we’re on to the election coverage.

COVID-19

This blog serves a few purposes, but one of the major ones is being a (public) journal. It’s interesting, for example, to look back at my thoughts right after the planes crashed on September 11. The spread of COVID-19 feels like one of those events that we’ll remember for a long time so it felt worthy of at least one post, but this probably won’t be the last one.

First of all, I feel like me calling it COVID-19 instead of “the coronavirus” is similar to my failed stand on calling drones by their proper name of “quadcopters.”

With that out of the way, let’s talk about how we got to this point. Right around the end of last year, it was becoming clear that something was happening in Wuhan, China. As I traveled to Israel around the end of January, there were a few thousand cases in China, and while I was in Israel, the first case was identified in Everett, WA.

From that point, it has continued to spread more throughout China and around the world. While the flu has hospitalized 3-4 times as many people as COVID-19 so far this year, there are two things that make COVID-19 scarier:

  1. The transmission rate appears to be a bit higher than the flu with around 2.2 people catching it for every 1 person who gets it.
  2. The death rate is much higher. COVID-19 is killing around 3.4% of the people who catch it and the flu only kills about 0.1%.

That’s what we know today. One challenge is that new data is arriving all the time as the world’s scientific community joins forces to figure this virus out. The numbers above might be totally wrong because we still don’t have a good idea of how many people have caught it. There are some theories that say 40-70% of people have already been exposed to the virus while others are saying that only a tiny fraction of people have been exposed. Or if we ignore that question, it makes sense that the virus is more fatal to the elderly and immuno-compromised, but why are kids getting infected at an extremely low rate? Is it because there’s something special about the virus? Do they have an immunity? Or are they always so sniffly and coughy that we don’t notice?

If COVID-19 really would take out 2% of the population and if we can’t stop it, that translates to 10s of millions of people dead. That could decrease dramatically if we take drastic measures and quarantine everyone. But every day you do that spreads panic and destroys the economy, so nobody wants to make that call. But if you want it to be effective, it needs to happen early or else it doesn’t help as much. There’s just not enough information to know what is the right decision.

As of Wednesday, the county where we live (King County) recommended that employers make it easy for employees to work from home if possible. My company quickly followed up with an email to all employees in this region asking us to default to working from home for the next three weeks. Our school district also closed for at least the next two weeks. Elijah goes to school farther north so those schools aren’t closed yet, but it’s not hard to imagine that they will follow in this path.

As I mentioned early, we’re the epicenter of the outbreak in the United States so the responses here are the most drastic in the country. The first deaths were literally a few miles from my house. As I drive home, there are news crews reporting in front of the school right across the street from my house.

Thankfully at this point businesses are still open and the supply chain is still flowing. Grocery store shelves are full (as long as you’re not looking for toilet paper or hand sanitizer) and gas stations have plenty of fuel. Driving around feels weird because traffic is so light with many people staying home, but everything else is fairly normal. It’s different from the shortages and quiet that you get when there is a snowstorm or power outage.

We ended up visiting the doctor today for a cough that Elijah’s had for weeks which morphed into a fever yesterday. Thankfully the fever disappeared quickly but the doctor still wanted to check him for pneumonia which can hit kids quickly. Both the nurse and the doctor wore face masks and plastic face shields. The appointment basically just confirmed that Elijah doesn’t have pneumonia or the flu and we can just watch it for a while. Oh and if you’re curious, our doctor is still flying out for a trip on Friday and has no concerns about doing so.

The news is flooded with stories ranging from speculation to useful facts as every website tries to get as much click-bait out there as possible. This is big money. My recommendation is to stick to sources like the CDC and WHO or simple, fact-based info like this handy dashboard from Johns Hopkins. Otherwise it’s easy to get sucked into a vortex of anxiety reading article after article about the unknowns and what-ifs.

I admit to getting sucked into that vortex as I think about how to care for my family through this situation. But the other night after one of those sessions of reading a few too many random articles, I laid in bed listening to the frogs croaking. They have no idea what’s going on, nor would they care if they did. I was reminded of the words of Matthew 6:

25“Therefore I tell you, do not worry about your life, what you will eat or drink; or about your body, what you will wear. Is not life more than food, and the body more than clothes? 26Look at the birds of the air; they do not sow or reap or store away in barns, and yet your heavenly Father feeds them. Are you not much more valuable than they? 27Can any one of you by worrying add a single hour to your life?

28“And why do you worry about clothes? See how the flowers of the field grow. They do not labor or spin. 29Yet I tell you that not even Solomon in all his splendor was dressed like one of these. 30If that is how God clothes the grass of the field, which is here today and tomorrow is thrown into the fire, will he not much more clothe you—you of little faith? 31So do not worry, saying, ‘What shall we eat?’ or ‘What shall we drink?’ or ‘What shall we wear?’ 32For the pagans run after all these things, and your heavenly Father knows that you need them. 33But seek first his kingdom and his righteousness, and all these things will be given to you as well. 34Therefore do not worry about tomorrow, for tomorrow will worry about itself. Each day has enough trouble of its own.

4k Video Editor Build

When we got our new Go Pro 8, I learned that my PC wasn’t new enough to play back the HEVC encoded video, much less do any editing with it. Sure, I could save the video in a different format, but I’ve been itching to upgrade my PC at home and this, combined with the 2.7K video that my drone records, was a good reason to go for it.

My requirements were that I wanted to be able to smoothly edit 4k video, view video in 4k resolution, and render edited videos as quickly as possible.

Every PC I’ve built or purchased before this point have been Intel CPUs, but lately, AMD has been kicking Intel around the block in terms of price to performance ratio. Just check out what the stock market thinks about the two companies over the last 5 years. The Ryzen 3770 seemed like a good price point for my build. It has 8 hyper threaded cores running at up to 4.4GHz. I built out a nice system around it with 32GB of DDR-3600 memory and an NVMe SSD. I’ve had no personal experience with that kind of SSD but wow, it’s FAST! Remember how much faster your computer was when you switched from a spinning hard drive to an SSD? This new drive is 10 times faster than the SSD in my last desktop. It reads data at a speed of 2.5 GB/second!

Here is the full parts list:

The build went pretty smoothly. The pcpartpicker.com website helped me avoid some incompatibilities. Once I got all the parts together, I flashed the BIOS, tweaked a few settings to get my RAM clocked up to the right speed and then installed Windows. Or rather, I tried to install Windows. It kept getting to about 60% of the way through and dying. As an “I don’t know what else to try” step, I rebuilt the installation media on the USB key and voila, it worked!

I capped it all off with a 4k monitor, the Asus MG28UQ. That felt like a splurge because my existing monitors were plenty good (though not 4k), but wow, once I got this all assembled, I ended up staring at YouTube demo videos and being amazed at the clarity. Plus it’s fun to see my drone footage in its full glory.

For a perf test, I fired up Handbrake on my old desktop and this new one, gave it a beefy video file from the drone and adjusted Handbrake with the same settings on each machine. This new machine got through it almost exactly 3 times faster than the old one. It’s not all roses though. I had a much nicer CPU cooler on the old machine and this new one is noticeably louder (but it has built in RGB leds… oooooo.)

It’s fun to have this new machine and it’s certainly going to make editing all those videos for church less painful. I’m also very excited to start watching things in 4k. I expect this will translate into a 4k TV before too long and then a 4k projector once my current one dies.

As a small reward for reading through all this nonsense (or at least scrolling to the bottom), here’s the first video I edited on the new machine. It’s all 2.7k footage from my Mavic Mini. Elijah and I went down to 60 Acres and took turns flying it around.

Seatback Phone Holder

I spent a few hours watching my phone on a recent flight before and ended up with a sore back from looking down at my phone for so long. That’s when I got the idea to make some kind of a phone holder hanger that would attach to the seatback tray table when it’s folded up.

But of course someone has already done it.

The good news is that there are a few different approaches to the scenario so you can pick your favorite. I used this Unitron World model on my flight to and from Israel and loved it. It worked quite well on all the flights I was on and it made it a lot easier to power through 34 hours of flights. They’re fairly inexpensive it’s not a huge deal if you want to try a couple different versions, but I really liked how solidly this one held my phone at any angle and how small it folded up.

School Auction Coasters

Back in October when I started Elijah’s dresser build, I thought for sure I’d be done in plenty of time to build something fancy for Elijah’s school auction in the spring. Nope. That dresser is the longest project I’ve ever done and I’m not anywhere close to finishing it. So I scaled down my dreams, but I think I still landed with a fun idea.

I started by gluing up a bunch of scrap pieces of random types of wood and planing them flat. Then it was off to the CNC to cut out circles. That ended up taking hours longer than I thought it would due to a comedy of errors. In retrospect I should have just cut them by hand, but I eventually ended up with 5 circles. The planned sixth one was ruined twice and it was unsalvageable.

From there I headed to work to use the laser cutter and after carefully aligning the laser with the reference marks that I made on the CNC, I engraved the Zion logo into the coasters. The walnut ones are my favorite and I think it’s especially neat how the “Since 1901” is perfectly lined up with the small strip of purpleheart.

I’ve never been to an auction like this so I don’t know if they typically have lots of small items or bigger ones, so hopefully this fits in ok with the other things that are available. I’m very interested to see a stranger attach a price tag to something that I’ve made.

YouTube Music vs Spotify

We’ve had the Spotify family plan subscription for many years and we get our money’s worth out of it, but I’m always willing to switch to something better if it comes along. YouTube Music is intriguing largely because it comes with ad-free YouTube and downloadable YouTube videos. The family plans for each are withing a couple bucks of each other so if I could get a similar music experience and add those two other features for about the same price, why not?

Before switching Tyla over, I tried using it for about a month. The first hurdle was that I have built up some big playlists that I use a lot on Spotify. It’s a non-starter to move more than 1000 songs over by hand so I paid for a month of soundiiz.com. It connects to various services and copies playlists. It’s not perfect but it was plenty good enough to make me feel like it was worth the cost.

Initially, I was impressed with YouTube Music. The selection seemed roughly on par with Spotify. For example, when i converted a 1000 song country playlist, it found over 980 of the songs. Additionally, YouTube Music had a couple albums that I haven’t been able to find on Spotify.

Unfortunately, after a month of usage, I couldn’t justify switching. My main interaction with music is on my desktop because I use it from work and YouTube Music only has a web interface. They have a Chrome App that at least gives you a separate window but the whole experience feels halfway done. Spotify is smooth and easy. YouTube Music isn’t.

I’ll keep an eye on YouTube Music because I’m still interested in getting downloadable videos (for trips) and ad free videos for roughly free, but it’s just not worth the pain yet.

1000 Beers

In early 2013, I signed up for Untappd and rated my first beer in the app: Fat Tire. Since then, I’ve rode the wave of the growing craft beer scene and continued to sample new beers whenever I have the chance. Recently, I tried my 1000th different beer, so I thought I’d share some thoughts and stats from my tour de beer.

Other than the first year when I was just getting into this, I average about one new beer every three days. 2019 was more like 2 every three days as I got closer and closer to the 1000 mark.

December is the month when I try the most new beers which makes sense because I have family members who enjoy craft beer too so we regularly bring new beer to family gatherings.

Dad jumped on the app early on and then Luke joined too. Logan joined later but he’s off to a good start. (Many other friends and family members have joined as well but this chart just shows the top users that I know.)

Ben (blue), Luke (purple), Dad (red), Logan (green)

Untappd has added more and more stops along their scoring slider but I stick to the whole numbers. I devote three values to fairly good beers and only two to the beers I don’t like as much.

5. Excellent beer. Search this out!
4. Great beer. Pick this anytime without regret.
3. Good beer. I would pay money to drink this.
2. Meh. If you hand me this, I’ll drink it but I won’t pay money for it.
1. If you had me this beer, I’ll decline.
0. Gross. I’ll pour this out.

Only a few beers have ever gotten a 0. One is Bud Light Lime and another is some disgusting jalapeno beer that I had at the beer festival. I couldn’t even get through my taster of it.

Overall my ratings follow a pretty normal distribution, skewed slightly toward the higher end which makes sense because I generally drink beers that I think I’ll like.

I started off enjoying mostly ambers and ESBs, but I’ve developed a strong taste for IPAs. Those dominate my fridge these days with New England style IPAs being my absolute favorite. Here is a breakdown of the different styles of beer (where I’ve had at least 10 of them) and the average rating for each one. Inside each category, I generally find both a 1 and a 5. It’s possible to make any style terrible or great.

StyleCountAverage Rating
IPA5463.46
Extra Special123.42
Blonde Ale173.29
Pale Ale1053.27
Pale Wheat Ale142.98
Pilsner322.91
Red Ale482.78
Lager572.19
Stout132.15

My average ratings have increased slightly over the years as I hone in more on the types that I enjoy.

Some people seem a bit skeptical when I rate a beer but countless times I’ve rated a beer and then looked it up to find that I’ve already had the beer… and I gave it the same rating years earlier. The first 100 ratings might be a little wonky as I figured it out, but since then I think I’ve been very consistent.

Finally, let’s look at my favorite and least favorite breweries. For this list I filtered to places where I’ve tried at least 5 different beers. Kevin has the well-deserved top spot!

BreweryAverage RatingCount
GBC – The Good Brewing Company4.3437

10 Barrel Brewing Company3.5019
Lagunitas Brewing Company3.5010
Founders Brewing Co.3.508

And here are the breweries that consistently make beer that I don’t like:

Elysian Brewing2.1811
BJ’s Restaurant and Brewhouse2.147
Blue Moon Brewing Company2.086

This has been an unexpectedly fun hobby. I keep saying that once I get to X different beers, I’m going to stop and just start ordering the ones I love. Maybe I’ll slow down a bit but I really enjoy trying new beers. Cheers!

Mavic Mini Review

Thanks to everyone who pitched in for my Christmas present this year: a Mavic Mini! Some of you may remember that I built my own quadcopter back in 2015 and while it worked well, I didn’t use it a ton and ended up selling it.

Fast forward to 202 and a few things have changed. Technology has improved dramatically and now you can fly 4k cameras around with high quality image stabilization with GPS signals feeding a bunch of automated flight algorithms. Also, I’ve given up on “quadcopter”. Fine. “Drone”. Whatever.

DJI makes a lot of very high end drones and the Mavic Mini is one of their entry level models. It was getting enough good reviews that I jumped in and went for it without doing a ton of research into the competing brands. Also, since this drone is only 249 grams, it’s on gram under the point where lots of additional FAA laws apply so you can skip some things like registering the drone.

I bought the “Fly More” kit which comes with some extra batteries, a carrying case, extra propellers and a few other things. I highly recommend it because while the batteries give you ~25-30 minutes of flight time, it’s pretty easy to burn through one before I’m ready to be done flying.

I saw a bunch of review videos online before I got mine, but actually witnessing it in person was still surprising. The video while it’s flying is rock solid. It’s like a tripod in the sky whether you’re hovering at 2 feet or 400 feet. (The drone will go up to 1600 ft by the FAA limits you to 400.)

There’s a remote that communicates with the drone but then my phone plugs in to give me a live view from the camera and adjust settings. Flying it is pretty simple as there are a lot of computers on board helping to hold you in the same spot when you let off the sticks and the gimble on the camera does a great job of removing vibrations or even large changes in direction.

I’m exited about the small size of the drone. I can easily fit the drone, batteries and remote into my hiking backpack so as long as I’m not violating any laws, I look forward to taking this on hikes. I should also be able to travel with it pretty easily so I can take it to Indiana and fly around home, fulfilling some childhood dreams of seeing my house from the sky.

The video from the camera is 2.7k at 40Mbps so the image is beautiful. It’s not a full 4k but it’s better than any monitor I own can display.

I put together a quick video from my first time flying it down at the school by our house. Prepare for gratuitous use of the drone in upcoming videos.
