@eigenhector Waiting for the subagents to finish thinking

[David Dolphin @ddol]

@eigenhector @xkcd @xkcdComic yeah, it'll be a while before the kiddos get to watch it, @CommonSense are saying 16+, like Blade Runner and 1984. they've got Interstellar and 2001: A Space Odyssey to look forward to in the meantime

[David Dolphin @ddol]

@eigenhector @xkcd @xkcdComic super cool! I've never seen Cloud Atlas, but you've convinced me, it's on our family watchlist now https://t.co/UIvwyYlANE

[David Dolphin @ddol]

@eigenhector they're both great, but Primer is one of my all time favourite films. it's well worth waiting until your second viewing before studying the detailed timeline diagrams, @xkcd jokingly highlights the story complexity in https://t.co/YwSEJzh2I6

🚸 "If the speeds don't drop, the work can't stop"

My City Hall testimony on Clarendon Ave (25mph school zone)

After repaving, speeds increased:
‣ median: +8% (33 mph)
‣ p85: +5% (39mph)
‣ max: 54mph

@rtwlz Fantastic idea Riley, sorry it got cut short

Is there any way you could upload an export of the dataset to Kaggle or the Internet Archive?

I would be very interested to explore the data to see if there are patterns (neighbourhoods or streets targeted / ignored)

[David Dolphin @ddol]

I spoke at SF City Hall yesterday about something I care deeply about as a parent: street safety

🚗 48% of cars speed on our block
😡 3 vehicles clocked over 50 mph
🚸 90% of pedestrians hit at 50 mph will die

If you want a radar when we launch sign up: https://t.co/nIUXymhzlL

@mariusschober @IterIntellectus A is for Apple, that’s good enough for me

@stephenrobles fake.

google livestreamed the skydive for their dev conference 12 years ago https://t.co/1wwOffNPS8

@maxdubler yeah, I think Buttonwillow outside Bakersfield is the closest to that experience, but not the same grade track. sonoma have a drag strip that’s more accessible but it’s not a racetrack https://t.co/ZqJHuqB1iL

[David Dolphin @ddol]

@maxdubler Nürburgring is an FIA grade 2 track

we have 2x FIA grade 2 tracks in the Bay Area (Laguna Seca & Sonoma)

it doesn’t curb street racing

@aloo @Waymo we don’t consume any media with advertisements (soma fm, spotify premium, youtube premium, jellyfin, &c.) so being forced to listen to shane co diamonds and o'reilly auto parts was jarring for my kid and a throwback for me to the time my car only had FM

[David Dolphin @ddol]

@aloo @Waymo not being thrown into an uber drivers world is a big factor

I take waymos with my eldest almost exclusively. we had to take an uber a few weeks ago (3min vs 45min wait)

driver was playing FM radio, eldest whispered to me when ads came on “why does he want to listen to this?”

@stefhatcher were you trying to find the department of health and human services in DC? because that’s their (two block) zip code

[David Dolphin @ddol]

@teej_m everything “IT” or networking. they’re allergic to Wireshark

DNS, UDP vs TCP, ICMP, ethernet frames, VLANs; basically everything ≤ OSI layer 4

I’m still shocked when technical friends think mesh WiFi is a good idea

@meanderingtripe @PMGilmartin flat bottom retort / boiling flask?
