Some transport simulation experimentation this rainy Sunday.
A strategy to improve walking efficiency is to reduce traffic signal cycle times to provide pedestrians with more opportunities to cross a road each hour. This is often opposed by the transport engineering profession as longer cycle times are seen to provide a higher throughput for motor vehicle traffic.
I’ve held the hypothesis that shorter cycles may actually be beneficial for motor traffic on inner-city-style roads that don’t have turning lanes. The idea being that turning vehicles would have more opportunities to clear the intersection (on the yellow light) if the cycle time was shorter.
Using SUMO (free and open source software), I put the hypothesis to the test.
For an intersection with very even demand, a 120-second cycle performed best for motor vehicles (this is the typical maximum cycle time used in Victoria, except for special cases). However, when the cycle time is reduced, the bare minimum of a 44-second cycle performed better than 100, 80, and 60-second cycles.
This suggests that to balance walking and motor vehicle outcomes, somewhere in the middle may not be the best option!
Even so, all the tested options were rather close, and a 44-second cycle was only an additional 99 seconds of delay for motor traffic across the hour compared with a 120-second cycle.
Caveats: The simulation used even traffic demands from all directions. This is unlikely to reflect reality. Also, I didn’t interrogate the simulation closely for this simple test. There may be quirks included that could change the outcome if discovered and removed.

FlapJax Receipt Relay Q41: Independent On-Chain Buyback Audit (2026-10-09 to 2026-10-21)
@rizky_pratama_id0x247FAF56AC01E666822aF2C68445eD03bBF94BE90x247FAF56AC01E666822aF2C68445eD03bBF94BE9 has never received a payout from FlapJax)0x642b0b54e35e416dacd8a6b27e6e40c63a8d0bc204218649cc229b02bdb2f074 (TSK-2E1NJWP3)
1. Audit Scope, Contracts, and Price Formula
2026-10-09T00:00:00Z through 2026-10-21T23:59:59Z (13 program days from 2026-10-09 through 2026-10-21 inclusive; the announced 14-day schedule runs 10-09 to 10-22).0x7C34E9e21eE28A49Ff0b84B61774119E6633359f0x90c8889f428F9Ebb77BB8f15CAD3a50a9aC680df (18 decimals)0xbb4CdB9CBd36B01bD1cBaEBF2De08d9173bc095c (18 decimals)0xcA93EC685b8623688E6B236f9068034B298c21500x1b81D678ffb9C0263b24A97847620C99d213eB14Explicit Price Formula (18 Decimals on Both Tokens)
In the PancakeSwap V3 pool 0xcA93EC685b8623688E6B236f9068034B298c2150, token0 is FLAPJAX (0x90c8889f428F9Ebb77BB8f15CAD3a50a9aC680df, 18 decimals) and token1 is WBNB (0xbb4CdB9CBd36B01bD1cBaEBF2De08d9173bc095c, 18 decimals). Because both tokens have exactly 18 decimals (10^18 wei per unit), no decimal-scaling exponent adjustment is required:
B - 1 (in BNB per 1 FLAPJAX):Querying slot0() on 0xcA93EC685b8623688E6B236f9068034B298c2150 at block blockNumber - 1 returns sqrtPriceX96.Pool_Price(B - 1) = (sqrtPriceX96 / 2^96)^2 [WBNB per FLAPJAX]
BNB_in_wei (10,000,000,000,000,000 wei = 0.01 BNB) and FLAPJAX_out_wei from the ERC-20 Transfer(pool -> treasury) log:Effective_Price = BNB_in_wei / FLAPJAX_out_wei = 0.01 / (FLAPJAX_out_wei / 10^18) [BNB per FLAPJAX]
The ~1.16% spread between Effective_Price and Pool_Price(B - 1) reflects the 1% (10,000 bps) PancakeSwap V3 pool fee plus price impact on the 0.01 BNB buy.

Note on Swap #7 (0xc999000f..., block 128086717): its UTC timestamp is 2026-10-17T02:00:51Z, which is 2026-10-16T21:00:51-05:00 (COT), whereas Swap #8 (0x6ec66780..., block 128178495) occurred at 2026-10-17T08:29:27-05:00 (COT). Counted in COT, there was at most 1 buy per day.4Daily buyback for 14 days (10-09 to 10-21 window check)1 DAY MISSED (2026-10-15 COT)No buyback swap was executed on 2026-10-15 (COT) between Swap #6 (2026-10-14T13:32:29-05:00, block 127643212) and Swap #7 (2026-10-16T21:00:51-05:00, block 128086717). Because the treasury held ~0.1069 BNB on 2026-10-15 (well above the 0.025 BNB minimum threshold), the 2026-10-15 skip was not triggered by the low-balance guard—making 2026-10-15 an unscheduled missed day.5Skipped if buy would leave treasury under 0.025 BNBKEPT (Guard Not Violated)On all 12 executed buy blocks, the post-buy treasury BNB balance remained strictly above 0.025 BNB, descending from 0.176853112 BNB at Swap #1 (block 126684151) to 0.036158610 BNB at Swap #12 (block 128946201).4. Non-Buyback Treasury Movements & Unclassified Items in the Window
Out of 36 positive-value outgoing treasury transactions between nonces 29 and 357 (2026-10-09 to 2026-10-21), 12 are the PancakeSwap V3 buybacks listed in Section 2, and 24 are non-buyback native BNB transfers:

Neither interacted with the PancakeSwap V3 router or FLAPJAX pool, so their off-chain operational purpose cannot be classified from chain data alone and they are excluded from the buyback tally.

FlapJax Receipt Relay Q41 On-Chain Buyback Audit (2026-10-09 to 2026-10-21 on BSC)
Pasting rough meeting notes into ChatGPT with "summarize this" usually gets you something that reads well and is hard to use. Action items are buried in paragraphs, owners and deadlines go missing, and occasionally the model fills a gap with something nobody said.
The fix is to tell it what you want in four parts.
TL;DR: state the task, the output format, the rules about what it may not add, and the length.
The four parts
Copy-paste version
Turn the meeting notes below into meeting minutes.
Use these sections in order: Decisions / Action items (owner, due date) / Next meeting. Put action items in a table.
Don't add anything that isn't in the notes. If an owner or date is missing, write "To confirm".
One line per decision, ten lines in total.
Notes:
Paste your raw notes after "Notes:".
Before you paste anything
We haven't included sample output here. AI answers change from run to run, so a screenshot of one answer wouldn't tell you much. The structure of the prompt is the part that carries over.
If you're building this into a tool
The same four parts map neatly onto a system prompt plus a structured output schema: format becomes the schema (an array of action items with owner and due fields), and "To confirm" becomes an allowed value instead of a free-text guess. That makes missing information visible in the data rather than hidden in prose.
