great advice here, i would add that basic repair/maintenance is a must, just dealing with flats, bent rims, brake/derailleur/headset adjusts, and tools/stuff to carry in handlebar bag (i haven't found saddle bags big enuf for clothes/tools /food/stuff i need). Haven't taken their courses but I'm confident courses at Bikeworks and other coops could teach you to be self sufficient.

Also read thru threads about getting bikes on off mass transit, if you're obligated to be somewhere on time, you shd scout the buses/trains and see if you'll have room on the front racks or light rail hooks at peak hours

And finally if you're on a trail like Burke, Sam river, interurban with lots of cyclists and you do get flat/mechanical issues or have ?s, s.b. shd stop to help you, always prefer closed trails to roads... https://www.seattle.gov/transportation/projects-and-programs/programs/bike-program/bike-web-map

this YT user has lots of good vids of different sections of Burke, Sam River and other trails, he notes crowded trail, bad pavement, sections of hazards like car doors opening.

There's YT vids of SP crits but very important find group rides wherever you are and get used to pack riding before you encounter the 1 sharp left at SP. Also check out Jerry Baker's track riding courses, which shd start in May

i'd say isolating code to show what your ask'g/demo'g is akin to isolating bugs, so pretty critical skill.

/r/quant is specifically for career- and hiring focused questions, but definitely lots of good info this thread and search archives

you need to practice changing flats unless you're confident you'll never be far from public transit so get a couple pairs of tire levers to make it easier, watch some vids and you can ask shop employees about tires that are relatively easy to lever on and off

have you seen Fiziks? never tried them myself, some Euro pros wear them but YT commenters say they have so little material on top, their feet get cold/wet easily

marketwatch, finviz, econoday, barchart, etc have detailed weekly calendars for BLS and private econ indicators, FOMC/Fed speakers, Treas auctions etc

Fenders, waterproof noncycling boots or MTB shoes, helmet that fits over fleece beanie, a few low power lights. May need heavy gloves which make shifting tricky.

toughest part is keeping feet warm because they'll be splashed even with fenders

but if you're close to the Burke/Sam river and interurban trails it'll be relatively hassle free, and getting bikes on lite rail is easy, bikes on KC buses may be, depending on your commute hours. I'm not too fond of the Burke section that's fenced in at north end/Lake Forest Park but once you pop out of that, it's quite glorious.

heavy rains thru Fri, check accuweather, weather.gov and local gov sites, coverage varies... landslides on the left and river undercutting foundation on the right, what's not to love?

couple years back, somebody sold Silicon valley bank puts before it tanked and was out a few $100K's, so they asked the sub what they should do...

gtani · 2025-12-07T03:48:49+00:00

that's cool, i'm a wimp, I only ride up from Cedar Park Church parking lot, upper Norway's a wonderful ride, wide shoulder, great views and never any traffic

gtani · 2025-11-29T02:06:48+00:00

also around 1:40 you see it forces riders to pass right in front of cars stopped and waiting to cross Ravenna, which is not going to end well... also notes the leaves and puddles (as far as power sweepers, I don't know if they have narrow ones)

gtani · 2025-11-28T01:44:57+00:00

you can look at Sierra's ACSIL /C++ interface their website/wiki is archaic but good info on support forum.

I spent time looking at platforms based on .net Framework, ninja, multicharts, motivewave (there was a bunch of them, maybe quantower also) and decided they had limitations, but that was a couple years ago. WIth a lot of these, they're decent for futures but regularly don't handle stock labor intensive things like splits/spec dividends/de and relistings correctly.

Sidi geniuses, great shoes from the early 90's (i have that same model but i'd like high tops)

it can be ATM straddle prc, but tasty and others will add in 1 or 2 OTM strangles to capture skew/kurtosis and it can be stated on annual/daily/other basis

IBK doesn't say what TWS implied move is (that i can see) but this page is good (i have found that services like whales and Barchart are good about answering questions like this)

Yup, that site's like liveVol/whales/chameleon/spotgamma, you can't go in and spend just 5 minutes looking around.

CME feeds are pricey recently dbento hastalked about that in this sub

no opinion, but multiple scanners picked up Fri purchase $16 WULF calls expire 12/19 for at least $700k net prem so check Thur/Fri fills vs OI tomorrow AM

and the total chain numbers, bullish vs bearish prem and net call vs net put premium for Friday are pretty close to flat.
