I've never ridden in Illinois, but yeah: > § 11-1512. Bicycles on sidewalks. (a) A person propelling a bicycle upon and along a sidewalk, or across a roadway upon and along a crosswalk, shall yield the right of way to any pedestrian

Unfortunately in many jurisdictions it is legally required to do that when passing a pedestrian.

Yeah, it's understandable that the real world is messy and user-sourced data can be very suspect. The case I'm thinking of is the eastern end of SR-520 over Lake Washington in the Seattle area. It has hundreds/low thousands o

Yet it's unclear to what extent they actually use them - on freeway adjacent bike paths that have different gradients than the adjacent freeway (typically steeper), it's very clear Garmin is using data referencing the freeway.

Well the login message I was greeted with on every ssh connection certainly threatened criminal prosecution for unapproved software at the extremely large bank I worked at. Unlikely? Sure. But a lawyer somewhere thought it was worth remindi

Also worth mentioning that "unapproved software" on bank infrastructure is what an aggressive prosecutor would call "felony bank hacking".

This is an explicit rule introduced at the beginning of most Caltech courses, so the norm is that that behavior is cheating due to being warned in advance.

Some professors would provide past exams for study aids or use them as homework problems. However, the explicit default was that you should not look at solutions from prior years. Professors would announce at the beginning of the course tha

The opening words of ACM95a my year are seared into my mind: "I would like to apologize to the students who took this course last year. I always aim for a mean exam score of 50 and a standard deviation of 10. Last year's mean was

One example of an adversarial university environment is how fraternities and sororities keep copies of exams and assignments from prior years. Professors know cheating is rampant, so have to change the questions every semester. Some courses

IIRC, CS1 was a mandatory class for other majors (like MechE) and a course in Scheme was basically hazing from their perspective. I forget if Scheme was moved to a later course or made optional.

As yet another housemate of Andy's at Caltech, it is perhaps worth mentioning that he was also involved in updating Caltech's CS curriculum prior to it becoming as popular as it is today. Hard to say how much of the trend is just

Definitely a bit of the former, but JPM and a few other big players have made similar moves.

As mentioned elsewhere in this thread, it's opt-in to avoid breaking existing behavior. But given that ingestion points are easy to identify, it's pretty straightforward to turn on (especially if you have a schema for your inputs)
19.
by qwhelan 7y ago
Yes, there's a lot of existing code written assuming the old behavior. But most code has only a few ingestion points, so it's pretty simple to turn on.

You should upgrade your version of pandas if possible - that's been fixed for a few versions now.

At hedge funds, the majority of your "cash bonus" can take the form of deferred comp that's locked up in a shitty fund that doesn't perform anything like the famous ones (both Citadel and RenTec do this). Some don't

FWIW it looks like pandas is slow/OOM-ing because the benchmarks solely use Categoricals, which aren't as heavily used by pandas users compared to R. In particular, I suspect the benchmark sizing is forcing falling back from numpy

>SIPC insurance up to 500K USD on all (non-crypto) investment accounts? This is on-par with the same kind of protections you get with any FDIC-insured checking or savings account. While similar, SIPC is not "on-par" with FDIC.

The crosswalk is not part of the intersection, so it's the latter definition. For example, blocking a crosswalk and blocking an intersection are separate offenses.

Nope, the airlines hate running those routes. They're highly competitive and thus terrible uses of very expensive assets. They'll be kept for expensive international connections, but the frequency will be dramatically cut. Also, w

The single LAX-SFO pair is about 10% of LAX's daily takeoffs, completely ignoring SJC and OAK. Throw in BUR and HSR effectively amounts to a significant capacity increase for non-short haul flights.
