Roland Dreier @rbd.bsky.social · 5hI know they say the Fed funds rate acts with “long and variable lags” but I wonder if this could be at least part of the story? 000
Roland Dreier @rbd.bsky.social · 5hThe fact that the trend started the same month ChatGPT was first released makes me think it was happening too early to be caused by AI 100
Roland Dreier @rbd.bsky.social · 5hOn the one hand it's a screenshot of an engagement farming Threads post, on the other hand it says ChatGPT did something bad, so I guess I'll uncritically believe it 150
Roland Dreier @rbd.bsky.social · 8hWell, fortunately a no vote on RTM just disciplines BART and leaves Caltrain and the county transit agencies unaffected 100
Roland Dreier @rbd.bsky.social · 8h”new cars are too expensive!” “don't you dare do anything to make them cheaper!” 010
Roland Dreier @rbd.bsky.social · 15hI work for Rivian, but yeah the R2 is NICE And if you can wait till next year for the standard trim, it's under 50 grand 021
Roland Dreier @rbd.bsky.social · 16hidk whose car this is but I'm always curious (parks at the same house as a Tesla with the plate “MOAR GPU”) 010
Roland Dreier @rbd.bsky.social · 16hI think until recently, being happy to be a good coder and stay at Senior SWE/L5 was a comfortable career, but now you're cooked if you don't do some tech lead/architect/Staff/L6+ stuff. You might still be cooked in a couple years, but you're definitely already cooked if you only crank out code. 010
Roland Dreier @rbd.bsky.social · 06/10/2026Yes, look at the ADS data on www.nhtsa.gov/laws-regulat... Tesla has 26 crashes reported total and to the best of my knowledge none of them involved serious injuries or fatalities.nhtsa.gov 010
Roland Dreier @rbd.bsky.social · 05/10/2026Tesla FSD is (despite the name) just ADAS. I think AV should only refer to vehicles that are claimed to be operating autonomously, and to the best of my knowledge Tesla robotaxis have never been involved in a fatal crash. 100
Roland Dreier @rbd.bsky.social · 05/10/2026That seems to be more of a Tesla influencer marketing strategy, tons of “watch FSD save my life” videos out there. Waymo seems to prefer a marketing message of “Waymo vehicles are observed to have fewer collisions at a rate that rigorous analysis of this data set shows is statistically significant” 030
Roland Dreier @rbd.bsky.social · 05/10/2026I think this is a reasonable frame but Vision Zero would argue for taking a broader systems view: human drivers have limited capabilities, but we can design transportation systems to mitigate the consequences of their errors so they're not fatal (and autonomous vehicles can be part of that) 120
Roland Dreier @rbd.bsky.social · 05/10/2026Funniest outcome is if both Prop 40 and 42 pass, but 40 gets a few more ‘yes’ votes so it takes effect 030
Roland Dreier @rbd.bsky.social · 05/10/2026Sure but is “died *while* colliding with a Waymo not *from* colliding with a Waymo” a rhetorical direction we want to go? 320
Roland Dreier @rbd.bsky.social · 05/10/2026To the best of my knowledge a Tesla AV has never been involved in a fatal crash? I understand the critique of their ADAS system but it's a little deceptive to lump those crashes into the same bucket & isn't Waymo saying “we're X% safer than human drivers” all the time pretty explicitly utilitarian? 110
Roland Dreier @rbd.bsky.social · 05/10/2026For example www.azfamily.com/2025/09/14/1...azfamily.comMotorcyclist run over after rear-ending Waymo near ASU Tempe campusOne person has died after a multi-car crash, one of which being a self-driving vehicle, near Arizona State University’s Tempe campus early Sunday morning. 010
Roland Dreier @rbd.bsky.social · 05/10/2026Pretty variable but the common thread is that a human driver did something bad in the vicinity of a Waymo vehicle 220
Roland Dreier @rbd.bsky.social · 05/10/2026Waymo does a lot of research that pretty unanimously finds their vehicles are far safer than human drivers: waymo.com/safety/resea... It's just, even with a rigorous safety culture and commitment to Vision Zero, if you're building cars, you do kinda have to accept a lot of shit will happen on roadswaymo.comWaymo Research: Published Safety Research Papers for Autonomous VehiclesSafety drives us. Learn more about the research we've conducted in the safety field for autonomous vehicles. 090
Roland Dreier @rbd.bsky.social · 05/10/2026Waymo vehicles have been involved in at least 3 fatal crashes since 2025 320
Roland Dreier @rbd.bsky.social · 04/10/2026A lot? If you were designing it from scratch now there are probably things you'd do a little better, but USB Type-C, USB-PD and USB4 kinda just work for a huge range of things from the cheapest throwaway gadgets up to 80 GBps workstation links? Hard to see a reason big enough to switch away… 021
Roland Dreier @rbd.bsky.social · 04/10/2026Musk coulda just bought Intel for like $250B a year ago 010
Roland Dreier @rbd.bsky.social · 03/10/2026IDK, is this cognitive surrender? Anyway wild that I can pull this shit and it just works in 30 seconds (Opus 5.5 high) 100
Roland Dreier @rbd.bsky.social · 03/10/2026Fair but an analogy I like is Chernoff faces - we have a lot of brainpower that's powerful & can be useful in thinking about models if we let ourselves use it, even if the models are simulacra 100
Roland Dreier @rbd.bsky.social · 03/10/2026So the challenge is that, as you say, anthropomorphizing does help us predict model behavior, a lot, right up until it doesn't 000
Roland Dreier @rbd.bsky.social · 03/10/2026Kinda surprised to see @leifw.bsky.social making this argument because while I agree models are computer programs and fundamentally not human - I also agree with him that LLMs are cultural technology that comes from human language and behavior. 210
Roland Dreier @rbd.bsky.social · 03/10/2026Intel Optane arguably suffered from the NVMe version being slowed down by PCIe/block overhead so not decisively better than SLC SSDs & the DDR version not being quite fast enough to be worth burning a whole (scarce, expensive) CPU memory channel. But on CXL.mem at 50+GB/sec w/ load/store interface… 010
Roland Dreier @rbd.bsky.social · 03/10/2026Why doesn't Micron (now a $1T company) bring back 3DXP? It was arguably ahead of its time but now the ecosystem is ready for it with CXL, and demand would be insane from AI hyperscalers en.wikipedia.org/wiki/3D_XPointen.wikipedia.org3D XPoint - Wikipedia 110
Roland Dreier @rbd.bsky.social · 03/10/2026Kinda the point of the frontier models now is that you don't have to baby-step them any more. But the scope of work they can complete independently or broad architectural context they can understand is still well below a human senior SWE. 020
Roland Dreier @rbd.bsky.social · 03/10/2026I'm using the word ”value” quite intentionally. We can agree to disagree but not even for sw engineering, for better or for worse, there's still a lot of economic utility to capture, when a senior engineer costs companies $25K+/mo and almost nowhere will spend more than $1K/mo/eng on agentic coding 010
Roland Dreier @rbd.bsky.social · 03/10/2026That's a somewhat different argument - that you don't need/want more capability, which is fair enough. For me it's clear the additional capability of Fable has value and there's still plenty of room for models to get better and offer even more value. 230
Roland Dreier @rbd.bsky.social · 03/10/2026Yes, I use Claude at work for sw eng; my employer pays for it up to a monthly budget. And I do use Fable sometimes because it's really f'ing good at figuring out hard bugs or completing big-ish tasks. (Although the last few weeks since Opus 5.5 launched, I find it seems roughly as good as Fable 5.1) 130
Roland Dreier @rbd.bsky.social · 03/10/2026I mean just draw a line from Opus 4.5 in November 2025 to Fable 5 in June 2026, I don't see how you can say they're running out of juice because there hasn't been another huge jump for a few months 210
Roland Dreier @rbd.bsky.social · 03/10/2026Opus 4.5 launched in November 2025! Saying the models are “sorta asymptoted” is like saying “eh, Apple hasn't been able to improve the iPhone for a long time” in May 2008. 180
Roland Dreier @rbd.bsky.social · 02/10/2026”going to take a few weeks and then see what's out there, but if you have an opportunity, please reach out! excited to see what my next chapter holds!” 000
Roland Dreier @rbd.bsky.social · 02/10/2026Remember correlation ≠ causation There's not really any plausible way that Trump becoming less popular could drive up fuel prices given the scale and liquidity of the global hydrocarbon market 000
Roland Dreier @rbd.bsky.social · 02/10/2026I know you're not serious but you could use the standard.site integration to get a “subscribe” button on your posts and then whip up a bot that listens for site.standard.subscription records and DMs users a link to the coffee page or something 😅 010
Roland Dreier @rbd.bsky.social · 02/10/2026idk about easy, Newsom is doing all this shit to probably get zero traction and drop out of the 2028 primary early? 020
Roland Dreier @rbd.bsky.social · 01/10/2026It's Newsom, so in a sense yes, he's nearly always doing politics as a shitposter www.theverge.com/policy/79849...theverge.comAmerican politics has devolved into shitposting and aura farmingThe Frog is owning the president. 140
Roland Dreier @rbd.bsky.social · 01/10/2026People did that repeatedly in the thread! but Bender is still acting as if it's an open question 130
Roland Dreier @rbd.bsky.social · 01/10/2026Good advice for senior developers too ... nearly everyone really 0290
Roland Dreier @rbd.bsky.social · 30/09/2026Yes I think remote work since the pandemic is a big part of it and that's definitely a mixed bag. But I think “there's nowhere to go” is an effect rather than a cause of people not going out as much. 000
Roland Dreier @rbd.bsky.social · 30/09/2026I guess I view “cocktails are too expensive” less as an explanation for why people socialize in person less and more as an excuse 270
Roland Dreier @rbd.bsky.social · 30/09/2026yeah for sure I don't get what you mean by “there's nowhere to go that isn't expensive” if you acknowledge the many places to go that are cheap or free? 1120
Roland Dreier @rbd.bsky.social · 30/09/2026Yes totally agree, the only thing I'm pointing out is that I can ride my bike for 2 hours and spend 2 hours in a cafe and still be home way more than if I spend 9 hours commuting/working in an office 020
Roland Dreier @rbd.bsky.social · 30/09/2026you can just open your door and start walking for free (I'm assuming you already have clothes and shoes) I'm being flippant but also serious. 1150
