@AliMomen425 @sasha_zabelski Pretty sure we peaked when we had that couch

@DCPoliceDept In the two years I’ve walked around Dupont, not a single car has stopped for me as I’ve walked the crosswalk at Connecticut and Columbia. Can we get a traffic officer or camera there?

[Ukraine / Україна @Ukraine]

To the free people of the world!

We feel your support. We see your demonstrations with our flags. We hear your chants. This helps us fight the horrific Russian evil.

Ukraine holds its ground ✊

We. Will. Not. Fall.

@AzizAbubsh As fun as it is to write, slow dramatic reveals of your thesis statement are not very fun to read

Do you think drivers in DC are terrible? There’s a reason: no consequences for repeated infractions, especially for drivers without DC plates. Check out the thread—

D.C. CM Mary Cheh kicking off a roundtable around DPW's booting and towing program, which she says is lax. 500k eligible vehicles to be booted, but only 2 teams booting 50 cars a day.

@jimthommo You would think those questions would be already answered by your t-shirt

[Steven Shorrock @StevenShorrock]

@Jdlee888 And "causes" is irksome here. Better: "Human error" is the cause assigned to 94% of crashes. In effect, actions and omissions by drivers are counted but those by road planners, designers, etc, are not.

BREAKING: CDC announces vaccinated individuals may gather together with up to 255 and form phalanxes once more.

Functional self-driving involves the *need* for abrupt driver take-over at fewer than 1 per million miles, per Tesla engineers. Currently errors are much higher, with the vehicle often not understanding when take-over should be required. This is definitively not Full Self-Driving

[Spencer Kohn @Spencer_Kohn]

Tesla engineers understand that their cars are not self-driving, even while Tesla and Musk advertise “Full Self Driving”. This dangerous dichotomy raises expectations and exacerbates drivers’ unpreparedness to take-over from the vehicle when required https://t.co/dAieBQD3gZ

I was the only person who ever checked it out from the local library— and I checked it out often! It was edited by Lucasfilm, so presumably it was canon before Leia became a Disney princess. Unsure if that’s still the case. Any experts of #StarWars canonicity out there? #501st

[Jordan Pascale @JWPascale]

@Spencer_Kohn Oooo is that book canon anymore though? I remember having it as a kid!

According to The Essential Guide to Weapons & Technology, not only is stormtrooper armor sealed against chem and bio attacks, but it has a 20min emergency supply of emergency oxygen. However, blueprints suggest that outgoing breath is unfiltered! Mask your stormtroopers indoors!

[Jordan Pascale @JWPascale]

This may be a dumb question, but would a stormtrooper, who is wearing a helmet, need to wear a mask?

Glad that 2021 is continuing 2020’s trend of every chart being an exponential function #GME #COVID19

If this isn’t a paper yet, someone needs to write it, along with a guide to correcting/avoiding these abuses

[Daniël Lakens @lakens]

Does anyone know if there already has been a paper written on the widespread abuse and misuse of Bayes factors? The more I look at papers that use them, the stronger my prior that they lead to more problems in practice than the use of p-values.

@imispgh I’m excited about the future of self-driving cars, but the combination of hardware *that is installed* and machine learning needs to be much better before it meets even the current assumptions and trust of drivers.

[Spencer Kohn @Spencer_Kohn]

Great analysis by AAA of how often (and why) "self-driving" features in current consumer cars fail. True self-driving vehicles are still a long way off. https://t.co/L67G68SMPq

[Spencer Kohn @Spencer_Kohn]

@imispgh “...cars were programmed to... ignore stationary objects. Designers assumed it would still be the job of the human driver to pay attention to the road and intervene if there was an obstacle directly in the roadway.” (2/2)
