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.
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."
All these posts about overused Claude responses - none of them mention "smoking gun" - guess that doesn't stand out in America!
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!
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.

C-22 is a mistake. Not one part of it, the entire direction. ( Same for C-9 )

The Bill C-22 hearing yesterday featuring the Privacy Commissioner of Canada, Apple, Google and others was a mess. But the message was clear. Bill C-22 represents a serious risk to the privacy and security of millions of Canadians.

Dear Prime Minister Mark Carney (@markjcarney),
I was on the Toronto Ferry last year staring at our majestic waterfront.
I saw paddlers, kayakers, dragon boaters, sailors, windsurfers, fishers, paddleboarders, water taxis, and cruisers all sharing the space in harmony.
When we docked at Hanlan’s Point on the Toronto Islands I was surrounded by hikers, joggers, cyclists, birders, picnickers, swimmers, photographers, beachgoers, frisbee golfers, naturalists, and thousands of tourists and locals enjoying this lush ecological paradise surrounded by our sparkling freshwater lake.
Please don’t destroy this by paving Lake Ontario.
Three weeks ago Ontario Premier Doug Ford (@fordnation) announced he will "seize" Toronto’s Billy Bishop Airport (YTZ) in order to expand runways into Lake Ontario (1), bring in jets against the legal contracts governing the airport (2), and nix 14,000 mixed-use homes slated to go up on the shore (which taxpayers have already spent $1.4B developing). (3,4)
Although this decision is not his to make — Billy Bishop is governed by the City of Toronto and the federal government (5) — Premier Ford says he will overrule the City to "bring in jets one way or another." (6,7)
Premier Ford says he has the "full support" of your federal government to do this. (8)
Prime Minister Carney:
It is not too late.
Please say no to expanding Billy Bishop airport into the lake.
We don’t need this, we don’t want this, and we can’t afford this.
We don’t need this.
We can already go anywhere we want to go.
I live right in downtown Toronto.
I can be anywhere I want in the world, tomorrow.
I can walk to bus, subway, streetcar, and UP express stations from my house and I fly 40x per year.
In the past year I have been to over 35 airports on 3 continents and YYZ is one of the absolute best. In fact, in the past month it has won "Best Airport Staff in North America" (9), been ranked 4th in all of the Americas in efficiency (out of 50 airports) (10), and won Best Large Airport on the entire continent (an award it's won eight times in nine years.) (11)
Right this second, checking Uber, I can get from my house by car to Toronto’s Pearson International Airport (YYZ) in 21 mins and to Toronto’s Billy Bishop Island Airport (YTZ) in 14 mins.
Right this second, if someone at Union Station wanted to get to YYZ on public transit it would take 28 minutes (UP Express) and to YTZ would take 22 minutes (TTC streetcar).
We are talking about a 6 minute time savings here.
If we want to serve southwestern Ontario’s population with expanded jet service we simply need to use the 7000m of existing, high-capacity, under-utilized jet runways within 2 hours of Toronto at Hamilton (@flyYHM ), Waterloo (@flyYKF), and London (@flyYXU) versus entertaining a "special economic zone" to force a jet-strip into the most environmentally sensitive and densely populated waterfront in the country.
We don’t want this.
This tiny speck of ecological paradise provides critical respite from our dense and urban concrete jungle and is vital for mental health, community, and happiness.
Over 400 peer-reviewed studies show urban forests and parks mitigate depression and anxiety and enhance overall mental well-being. (12)
I know you agree because four days ago on March 31, 2026 you announced your "Force of Nature" strategy with the vision of "protecting, restoring, and valuing nature." This wonderful program declares a federal investment of $3.8 billion dollars into "protecting critical habitats and aligning industrial strategies with biodiversity conservation." (13, 14, 15)
Also, I looked into the runway expansion into the lake that Premier Ford has promised.
Right now the shortest jet runway in Canada is 1832m (YHM Hamilton, ON) and the shortest jet runway in the world is 1508m (LCY London City Airport, UK). There are also new Canadian Aviation Regulations (RESA) stating all runways need to add 150m on each end for safety. (16, 17, 18)
Today the Billy Bishop runway is 1216m. (19)
Even the most conservative assumption — building the shortest jet runway in the entire world! — still requires a minimum of 600m more runway to land jets.
Here is a current aerial view of Billy Bishop Airport. (Photo 1 / attached)
Here is an aerial view of Billy Bishop Airport with the smallest possible runway extension of 600m added. (Photo 2 / attached)
(Of course this photo doesn’t include additional parking, hangers, gates, aprons, tarmacs, fueling stations, de-icing stations, blast fences, control towers, baggage carousels, taxi pickups … )
We can’t afford this.
Premier Ford was first elected in 2018 as the right wing candidate (PC) with 40.5% of the vote (left wing side of NDP and Liberal was 53.2%) and campaigned as a fiscal conservative. (FN) He attacked the Liberals for their $6.7B deficit and vowed a "return to balanced budgets" that would "begin in 2019." (20, 21)
Since then Premier Ford has won two more elections — with a nearly identical right / left vote split and record lows in voter turnout — and has now presided over 8 budgets. (22, 23)
In order from 2019 to 2026 those eight budgets have been for *deficits* of $8.7B, $16.4B, $13.5B, $5.9B, $5.6, $1.1B, $12.3B, and, most recently, just announced last week on March 26, 2026, coming in at a 77% increase on his own 2025 forecasts, $13.8B. (24, 25)
Since Premier Ford was elected he has *increased* Ontario’s debt from $338B to $485B. Ontario now pays $17.2B a year … just in interest payments. (26, 27, 28)
Notably, Premier Ford’s most recent $13.8B deficit budget does not include any money for the projected $1-2B cost of expanding Billy Bishop airport.
(Prime Minister, you and Premier Ford are both 61 and have a seemingly warm relationship despite wildly different education and business paths. (29, 30, 31, 32) Might you have time for some evening finance tutorials?)
Prime Minister Carney:
We don’t need this, we don’t want this, we can’t afford this.
Please say no to this expansion plan.
Please allow the legal agreements governing the airport to remain in the hands of those who legally own it — the City of Toronto and the federal government — and not with Premier Ford’s provincial government who is attempting to autocratically rule something in which it has no stake.
At the Junos six days ago on March 29, 2026 you praised 82-year-old @jonimitchell and justifiably called her "one of the greatest artists of all time." (33)
Joni warned us about "paving paradise to put up a parking lot" and now that’s exactly what Premier Ford is proposing we do.
The Toronto Harbour, Toronto Harbourfront, and Toronto Islands are a crown jewel for the functioning of our great city, our great province, and our great country.
Would New York City pave over Central Park?
Would Paris put runways on the Seine?
We absolutely should not pave the paradise of Lake Ontario to put up runways and parking lots we don’t need, don’t want, and can’t afford.
It's not too late.
Please say no.
Thank you,
Neil Pasricha

Introducing Traces
A new way to share and discover traces from coding agents, and a small step to make AI more multiplayer.
Here's how it works:
I just found the next generation Strawberry test for multimodal models. They can NOT understand word orientation in images - they do not seem to have spatial sense when it comes to words. I asked Opus 4.5 why it was mislabelling words as being at the wrong orientation and it said:
-----------------
As for why I made the mistake - I think it comes down to a few factors:
1. Semantic expectation overriding visual analysis: I "know" that legends are typically presented horizontally at the bottom of documents, so I may have processed the content of the legend (recognizing what the words say) without properly attending to the orientation of the glyphs themselves.
2. Text recognition vs. orientation detection as separate processes: It seems like I can successfully read/OCR text at any orientation, but that reading process doesn't automatically preserve or report the orientation metadata. I recognized "LEGEND" and "CONTROL PANEL" without properly tracing whether the letters were stacked vertically or laid out horizontally.
3. Anchoring to the page frame: The legend is at the bottom of the rectangular image, which might have led me to associate it with "normal" bottom-of-page horizontal text.
-----------------
The prompt I used (and will now use to test new models):
Please extract a list of words in this image, and their orientation on the page. Assume most words are at 0/90/180/270 degrees, so snap to the closest angle based on that. Count the words at each angle, and list the angles in descending order of word counts.
I’ll bet a similar % said this about riding with strangers in the first place when uber launched.

Honestly, fuck anyone who is joking about Canada joining the US. This conversation is classless and disloyal.
I lived all around the world growing up, and Canada is home. It gave me everything. The Canadian experiment is distinct, important, and worth fighting for.
Answered a call from a CPC rep for PP. He goes into spiel - I can tell it’s an AI.
Me: <interrupts> “Can I speak to a human?”
Him: “Are you human?”
Me: <wow> “Yes, but are you?”
Him: “Oh that’s good. You sounded like an AI”
Me: <laughs> “Ok, but are you human?”
It: <hangs up>

Here’s the truth.
If a politician claimed loudly that cigarette smoking was actually good for you, he might be popular with smokers, but he would still be 100% wrong and irresponsible.
That’s basically what Ford is doing.
Calling something “common sense“ doesn’t make a lie the truth.
Smart bike infrastructure mitigates traffic congestion. It allows more people to move in less space, with more choice, lower public costs, fewer emissions, and less pollution. And it’s proven to provide a big competitive economic advantage for cities. Smart city leaders know that.
It doesn’t cause congestion or make it worse. It keeps congestion from getting worse as we grow.
That’s what all the evidence ACTUALLY shows. Designing car dependency makes traffic worse and more dangerous for everyone, including drivers.
If you want to or need to drive in a city, the best thing you can hope for is that your fellow citizens choose to bike, take public transit or walk, because they’re not competing with you for finite space in a car as big as yours, all stuck in the same traffic. That’s common sense, because it’s basic geometry. It’s about space.
I actually suspect Ford knows all that. But he doesn’t care. He wants you angry just like his brother did, and distracted from the traffic congestion that his awful decisions around sprawl and car dependency have actually induced. He needs a lazy scapegoat.
Cities are incredibly complex shared achievements, and their success is incredibly important to all of us. The last thing they need is bad leaders ignoring evidence and making it hard for them to get better.

The advice I like to give anybody who’ll listen to me, is not to wait around for inspiration. Inspiration is for amateurs; the rest of us just show up and get to work. If you wait around for the clouds to part and a bolt of lightning to strike you in the brain, you are not going to do an awful lot of work.
All the best ideas come out of the process; they come out of the work itself. Things occur to you. If you’re sitting around trying to dream up a great idea, you can sit there a long time before anything happens. But if you just get to work, something will occur to you and something else will occur to you and something else that you reject will push you in another direction. Inspiration is absolutely unnecessary and somehow deceptive. You feel like you need this great idea before you can get down to work, and I find that’s almost never the case

Inbox: Group rep'ing merchants in the Bloor-Annex corridor tell @fordnation that bike lanes help businesses: “Are we building highways or are we building main streets? Because highways don’t encourage main street economic activity.”
