@mrkrishsatya This. So much this. Personally I had a lot of momentum with opus 4.6-4.8 and it got squashed. But it’s back - and better than ever.
@ScottPolhamus @Tesla Can confirm it really seriously ignores the speed signs on the 401. Not sure why, but they don't show in visualization at ALL. Map data is definitely out of date for a number of the 110kmh regions.
So many posts about killing comments/docs in your repos, as "the code is the documentation". Who tested this in their codebase? I cut out 75% of comments from my monorepo, and on eval test set of 20 issues, mixed across execution and comprehension, the scores were the same for performance. Token usage went UP. It was a fail. Turns out comments help. Agents had to parse through MORE file content to obtain the info vs from decently formed comments and context inline with the code base. In short, what works for humans also works for agents parsing through your content.
@DriveTeslaca It will keep you safe - but it will also do this with dark tire skid marks - it's tuned for paranoia.
Prevent Claude's "historical account of everything we've ever done" verbosity: "Comments and docs are present tense: they describe what the code does now. Past tense (what it used to do, why it changed, what a fix found) go in the commit message, PR, or ticket. A "past tense" comment should stay only when a reader would be tempted to change the code back."
@Google Really not cool to switch the lake name when your SDKs/APIs default to "US" and expose things in embedded maps that are not wanted in other places. Perhaps default to the caller's location, just like you do on the maps site itself?
@kinsellawarren Voters already did - removing Christine Hogarth and electing Lee Fairclough. A clear rebuke in the exact area of the bike lanes in question.
All these posts about overused Claude responses - none of them mention "smoking gun" - guess that doesn't stand out in America!
@DirtyTesLa It’s too often used when it’s new to the poster - not new in reality - so it has become the proverbial “boy who cries wolf”.
@DirtyTesLa It must have gotten FSD v14 lite ;)
@DannyLimanseta These models don’t have spatial sense. The new strawberry test is to see if it can reliably tell an image is rotated upright. They can’t! They fabricate up/down/left/right and fundamentally do not understand. Asking to analyze relative proximity of objects in images also fails.
Help me win (or lose!) a $1,000 bet. What does this date mean: 2026-04-06. Think about it, then click into the thread for the poll. Don't be biased by the poll options, decide before you click, and 1st thought only!
@DriveTeslaca Calibration did nothing in my case. It still wobbles and brake/accel stabs. Worse at highway speeds or on hurry, but present other times as well.
@listenntalk Now that I've been driving around Toronto, it's a stark difference - in the city (specifically when other cars are present ahead - which is most of the time) - it's great! Only when there's nothing to follow out on the open road, it gets shaky/stabby and is horrid.
FSD 14 lite. So bad, I went back to autosteer. It is such a horrid regression - I’d like V12 back. Accelerator stabbing. Brake stabbing. Bad nav. Inability to read speed signs on major highways. Wrong speed on major highways. Yes cams are re-calibrated & clean.
@listenntalk I’m guess that’s the sweet spot. Urban cores - which are super important! See how it is on the highway or anywhere with trees/shadows/unattended crosswalks. Not much of my driving is downtown.
@listenntalk Out of curiosity - do you use Hurry mode? I found the accelerator stabbing only happened in Hurry.
@boardyai @andrewdsouza "building a new e-commerce platform at Ritual to make food delivery even faster. want in on Boardy Pro" - was the template Boardy figured out. Maybe Pro will figure out what I'm actually up to ;)
C-22 is a mistake. Not one part of it, the entire direction. ( Same for C-9 ) citizenlab.ca/research/analy…
