gullywhumper··on I walked across Luxembourg
For my 30th birthday a group of friends and I walked the perimeter of Manhattan island. Except for a section along the Harlem river, there are paths along the water the entire way so it required almost no navigation. We picked up and dropped off friends along way that only wanted to do parts of the walk. And we stopped at several bars too, meeting other friends that just wanted to have a drink. We started at 8am and finished just after 4am. I would definitely do it again, even without the friends or bars - but they definitely made it a memorable adventure.
gullywhumper··on Basic Physics of Rowing (2007)
There's an efficient ratio between the drive and recovery. At 20spm a 1 second drive means 2 seconds on the recovery (so a full stroke is 3 seconds). Try rowing that rating at a ratio closer to 1:1 and you'll really notice the inefficiency. You couldn't do that for an hour and maintain a decent split. As power and rating increase, you want to maintain a ratio. I don't know if it's always 1:2, but there's still an efficient ratio. A similar idea might be being in the wrong gear on a bike. On flat ground with no wind, if you're in the wrong gear you might be able to pedal at a very high rpm, but you'll probably notice that you are not moving efficiently. So avoiding rushing the slide isn't as much about free speed or checking the boat, but being in the right gear. Definitely not a physicist - so maybe not the best analogy, and maybe I'm misremembering how my coaches had explained it to me.
gullywhumper··on 129-year-old vessel still tethered to lifeboat found on floor of Lake Huron
While down from its peaks, Duluth is still a very active harbor. [1]

There are regular harbor cams and freighter watching videos on Youtube. [2][3]

There is an old lake freighter open to tour. [4]

There are several good breweries (probably better quality than what would have been available peak Duluth!).

The University of Minnesota does have historical aerial survey photos of the port starting in the 1930s, but modern Google Maps satellite is probably better to get a sense of the port. [5]

If you travel up the north shore, Two Harbors is also still an active port. There's a good brewery there. And still further up the coast, there's also an old lighthouse that can be toured. [6]

Not a local, just a fan. But as a fan of history, I agree it would be so interesting to time travel.

gullywhumper··on Pedestrian Traffic Fatalities by State: 2022 Preliminary Data
Even in supposedly bike and pedestrian friendly Minneapolis, the drivers are terrifying. The traffic dampening measures the city has put in do very little to slow the aggressive drivers, and there is next to zero law enforcement. Before becoming a parent, I was very deliberate about where I biked / ran / walked. Now with a toddler, I only walk a very limited number of specific routes at specific times of day that try to minimize potential interaction with drivers. After 8 years in NYC and 3 in Dallas, I was so excited to move here. Now I'm desperate to leave - 100% because of the drivers. But I haven't figured out where drivers don't dominate somewhat affordable urban living.

gullywhumper··on Pele's Hair
~20 years ago in college one of my best friend's had a 'break stuff' party in the basement of his off-campus house. The party goers took anything they could find around campus - things like discarded printers, etc - and destroyed them in the basement. Given it was a party, they also had lots of empty bottles of beer. The next morning, after spending some time in the basement cleaning up, one of the housemates came upstairs coughing blood. There were enough glass particles still in the air that he had inhaled some.

gullywhumper··on Economists are flocking to Silicon Valley
I remember Marginal Revolution talking about this a while ago (2016):

    For the moment, Amazon seems to be the most aggressive recruiter of economists. It even has an Amazon Economists website for soliciting résumés. In a video on the site, Patrick Bajari, the company’s chief economist, says the economics team has contributed to decisions that have had “multibillion-dollar impacts” for the company.

    Another Amazon jobs site lists openings for economists. As of Friday, there were 34.

    Seeing this emerging job market, the National Association for Business Economics held its first meeting for technology company economists in April in San Francisco. Another is set for October in Silicon Valley.

gullywhumper··on A wild turkey is attacking people in D.C.
I used to live at 1st and Hennepin overlooking the Hennepin Ave bridge. During the lockdowns there were at least 4 times I remember either lone turkeys or small groups coming over the bridge in the middle of the day.

And just yesterday, driving through the tangle of 35/94/55, my wife pointed out a dead turkey on the side of the road.

gullywhumper··on J. Kenji López-Alt says you’re cooking just fine
Kenji's channel and writing are great windows into how cooking does not need to follow rigid rules and precise measurements to make great food. He substitutes ingredients and uses what he has on hand all the time. Unless it's something like bread or pizza dough, where he needs the correct ratio between flour and water, he never measures or weighs anything. He frequently leaves something baking in the oven or simmering on the stovetop, promising to come back in X minutes, but it's usually Y minutes later because he's been off doing something with his wife/kid/dogs. It seems like he says things like "oops" and "but that's ok" a lot. Cooking shouldn't be intimidating. He shows how approachable and forgiving it can be.
gullywhumper··on Rare real colour photos of WWII
I like pics like the one in Cologne [1] because I try to find them on Google street view.

The alignment of the spires in the original makes me think it's either taken from the north or south.

- Here's a current view from the north [2].

- Here's a view from the south [3].

My guess is that it's from the south and in approximately the same location as [3]. Without going too much further down the rabbit hole, I'm assuming:

- The Allies approached the city from the south.

- The original pic doesn't show the train station, which I don't think was destroyed during the war.

- The buildings in the original look ruined and the street view has all post-war buildings.

If anyone is a better lunchtime detective, happy to be corrected! And if you could help me figure out who is in the portrait in the foreground, that would be much appreciated!

gullywhumper··on AirPods don't “just work”
My annoyance is that gen3 audio controls are significantly more difficult to use. With gen2 it was possible to simply tap the side of the airpod to pause, skip, or go back, and the user had the option to set which side controlled that functionality.

Gen3 has a sensor that has the same functionality, but it is more cumbersome to use. The sensor is small and angled in a position that makes it more awkward and difficult to access. It requires some precision and dexterity - a pinch rather than a tap. The sensor is on the stem of the airpod, so it feels less secure to press. There is also a small click when the sensor is pressed that gets annoying.

I live in a cold environment and frequently have to wear multiple layers of gloves, mittens, hoods, and hats when I go for long walks, so I lose that functionality.

gullywhumper··on My indoor rowing tips after 15M meters
Below are my two cents as a former high school and collegiate rower, an occasional assistant coach since then, and someone who hopes to continue to erg until they dump my ashes unceremoniously in some river, lake, pond or even bog.

Hopefully a couple tips that may be helpful for beginners:

- If you can set up a mirror or some other way to watch yourself row, do it. It's not a natural motion for beginners and what it feels like you're doing can be very different than how it actually looks. Good rowing vs beginning rowing can be like watching a professional golfer or baseball player swing vs someone who has picked up a club or bat for the first time. It's fluid, controlled, and powerful vs awkward, jerky, and underpowered. It takes time, patience and persistence.

- Rowing is mostly legs and it's an endurance sport. If you're doing longer workouts at lower strokes per minute, it might not feel like you're doing a whole lot until deeper into a workout. Your legs are effectively your strongest muscles. Guys especially have a tendency to try to use their upper body more, and frequently break their arms right away at the catch. Breaking the arms early is counterproductive because it weakens the leg drive. Let those arms hang on the handle and let the legs do most of the pressing. Think deadlift / hang cling. Legs do most of the work, upper body and arms finish what the legs started.

- Don't squeeze the handle. You can even put your thumbs on top like a pull-up to help you get used to hanging on the handle with the upper body.

- There should be an approximately 2:1 ratio between the recovery (the time you're moving up the slide to the catch and compressing your body) and the drive (when you're pressing with your legs and then opening up with your body - the part where you're doing the hard work). So at 20 strokes per minute that's a 2 second recovery, 1 second drive. That ratio is important whether you're rowing at 20 SPM or 40+ SPM. There's a tendency for newer rowers to go at more of a 1:1 ratio, which is inefficient. It's similar to being in the right gear on a bike.

- On the recovery, the handle should come into the catch at roughly the same height it comes out during the drive. When coaching, we would sometimes put water bottles between a rower's feet on the erg so that they wouldn't let the handle/chain drop too far and knock the water bottle over. You'll get a stronger, more effective drive with a good catch.

- On the recovery, don't break your legs until after the handle gets over your knees. So really let yourself stretch out of the finish. This is especially important as you get tired. If you break your knees before the handle clears, you tend to have to lift the handle and then it will drop after it's over the knees and you'll likely have a bad catch.

- If you're on a Concept 2, don't set the fan at a 10. I've trained with Olympic rowers and have never heard of anyone going over 6. In the 3-5 range is perfectly fine. There is no glory saying you row at a 7+.

- When I erg now, I watch soccer (45 mins with no commercial interruptions) or train POV videos on Youtube, and I use Airpods to listen to music.

- And for what it's worth, I don't think I've ever heard of any HS or collegiate program using anything other than Concept 2 ergs. I've hopped on other rowing machines at gyms, but found they felt awkward and less fluid. I don't know what some of the newer, higher-end machines feel like. They could be great.

gullywhumper··on Surveys show Americans want more walkable cities
To make cities more walkable, changing driver behavior needs to be a significant focus.

Minneapolis consistently ranks as one of the better cities for pedestrians, but even here the drivers here are really aggressive towards pedestrians to the point that some don't even care if you're pushing a stroller. Bike lanes, trails, and enhanced crosswalks are great, but they can't protect you from drivers that ignore traffic laws and drive dangerously.

The city knows it has a problem. This picture taken today is of a sign posted on one of the main bridges into downtown:

gullywhumper··on Alcohol-free beer is fizzing
3.2 is not just available for sale, there are still 3.2 bars in Minneapolis as a relic of a law from 1884.[1]

3.2 is the only beer that can be sold in grocery and convenience stores (grocery stores have separate alcohol stores that sell higher content beers, wines, etc.). From the article, CO, KS, OK and UT also sell 3.2.

gullywhumper··on America’s bald eagle population continues to soar
I live about 3/4 mile up river from a nest along the Mississippi River. My office overlooks the river and I keep a log of every time I see one flying by. You can walk almost under the nest, and when they're home you can get a sense of just how large they are. After 4 years of living here it never gets old - I dread the day we have to move.
gullywhumper··on In January, there were more real-estate agents than homes for sale in the U.S.
The housing market is bonkers in Minneapolis. This Saturday we put an offer in on home that went on the market Thursday. There were 31 other offers. We offered 20% over asking, but didn't get it. That was our fourth unsuccessful offer so far. Three of the winners for the other offers supposedly had both appraisal gaps and waived inspections.
