I figured that, now that I'm back home, I'd take maybe .5-1hr per day to learn a little python because it's handy. Today's task: install the stuff I need to go through the Jake VanderPlas book on python for data science. I think I've successfully done so. I won't verify until tomorrow, though, when I actually give it a whirl: I've gone through my allotment of time!


I don't have any plans to do anything besides R (with dropping down to C/C++ as appropriate), but having a vague idea of what's going on in Python and not being completely helpless is a good idea. I might also look at a DataCamp course or two.

I ended up giving up and buying a replacement tablet. So the thing was crashing, like, about a minute after booting. I tried to do the factory reset, but that crashed a minute after the boot. Oof. Fortunately, pretty much everything is backed up thanks to the wonders of the Googles.

Apparently google dropped support for third party chat clients? That's a shame.

I installed Signal the other day.

I didn't end up reading another book yesterday. This is fine.

the mother-in-law send me a pair of Einstein socks. This is good.

I've been riding the exercise bike at the gym a fair bit recently - I need some steady state exercise in addition to the lifting and it's too cold/snowy/rainy to run. It's on a timer which cuts out after 30 minutes, so that means I'm typically on there for 30 minutes or sometimes up to 60 (more only possible if it's not crowded at the gym - also depends on bus schedule). I typically use the recumbent bike because the upright hurts. So it says I go about 8 miles each time and am at like 130 bpm - but I don't have my hands on the sensors that much during it, spend most of the time dinking around on my phone, either surfing the web or doing Esperanto learning apps (while listening to a podcast). Cadence is usually around 75ish. I have no context for understanding that or the mileage - I do have context for understanding the pulse (in theory).

Not teaching next semester. Back on new iteration of research grant. Seeking Justice!

Context. Its a pretty relaxed pace by marvin (4.00 / 1) #1 Thu Dec 27, 2018 at 01:00:56 AM EST
I'll ride like that with my wife or co-workers. That pace and effort level is equivalent of riding along a rail trail, chatting, and not breaking a sweat unless it's really hot outside.

90rpm is the typical cadence recommended for road, but lots of people only do 80. 75 is getting a little slow. I start bobbing up and down by around 100-110, but I'm always guessing a bit since I don't have a cadence sensor.

I'm only a few years away from being 50, and my ride today was 72 minutes with an average heart rate of 152. The ride included a half hour block between 160 and 175bpm. 130bpm seems low for your age for cycling.

Ignore the mileage reported by those machines. It's only slightly more realistic than the calorie counters, which are entirely fictional.

Yeah, low nineties is usually the target by lm (2.00 / 0) #2 Thu Dec 27, 2018 at 08:07:41 AM EST
... for endurance biking anyway. If you're slower than that, gear down until 90 is as easy as 75.

But it may vary on a recumbent. I know next to nothing about bents except that they look silly.

If the upright hurts, it doesn't fit ... by lm (2.00 / 0) #3 Thu Dec 27, 2018 at 08:09:54 AM EST
... or you've got something to see a PT about.

Unfortunately the ones in gyms only have so much adjustability.

The folks seriously into cycling don't pay much attention to speed but look for watts over time.

It's the seat and lack of adjustability by gzt (2.00 / 0) #4 Thu Dec 27, 2018 at 09:22:12 AM EST
Not many degrees of freedom and it gets me just wrong. I can, in general, ride a bike.

That sucks by lm (2.00 / 0) #6 Sat Dec 29, 2018 at 12:25:32 PM EST
But that's par for the course for a stationary bike in a gym.

If you want to make it a little more interesting do 90 seconds all out followed by 4:30 at the pace you've been doing. Repeat.

I should resume my Python studies by georgeha (2.00 / 0) #5 Fri Dec 28, 2018 at 11:09:33 AM EST
I have to show some competence in a technical field, and they didn't offer any fields that I already have competence in. Python seemed the least bad choice.
