A widely cited 2025 meta-analysis claiming ChatGPT improves student learning was just retracted by Springer Nature in a two-sentence note plus a non-responsive-author disclosure. The methodological case against it had been public for the entire year between publication and retraction. Where's the publisher transparency, and where's the cost to the authors?

2026-05-02T01:42:35Z

A new preprint finds that finetuning frontier LLMs on one author's novels unlocks verbatim output from dozens of other copyrighted books the model never saw at finetune time. The real finding is the control: synthetic-text finetuning produces near-zero extraction. So the copies aren't in the finetuning data. They're latent in pretraining, and finetuning just exposes them. This could shift copyright liability from customer to lab.

This #LongRunSunday I ran a pretty short & controlled 10mi: time 1:39:35 pace 9'47”/mi with avg/max HR 134/141bpm.

I did have to clear out mucus from nose & throat from time to time, but otherwise felt great during & after run! My HR was still a bit high, but I’m clearly improving!

This is also the first time in 2026 that I reached my weekly target of 48mi in #running!

My left ankle has been bothering me since many sprained ankles 30 years ago from aggressive basketball playing. 🙂

But it only started showing itself more prominently in the last 6 months or so. I think there's a new imbalance introduced due to my evolved shape/form which placed more pressure on it. I need to visit PT for a closer look.

After hot cocoa and some nuts & M&Ms at the end of loop 5, I felt a bit better and restarted my engine. I regained a bit of speed towards the end and finally finished the race.

I was worried about my HR, but #CoachGPT assured me in its postmortem it's due to the mechanical failure of my left ankle/calf/knee chain with reasonable logic.

Next race is in March -- plenty of restoring/recovery work to do in the meantime!

My HR went haywire: every time I started even shuffling, it’d shoot straight up, even to 185bpm! I'm happy my heart can still beat this fast (should be ~170 considering my age), but my typical HR on this course should be <160. The rest of the race became a HR management exercise: I basically walked 3/4 of loop 4 and the entire loop 5!

DNF did cross my mind, but I decided to at least finish loop 5 and see.

A day after my disastrous Bridle Trails 50K race: I barely finished it with 6:06:57 -- more than an hour longer than what my goal was!

The initial 2 loops (~10mi) went fine, but starting from 11th my left ankle/calf started going wrong. Looking back my spiked HR should've been a sure early warning. Starting my 4th loop I basically had a "cotton-candy" left leg: too weak to actually run on it! I walked 3/4 of that loop.

Final run in #Taipei Stadium in this trip: a 5mi “easy" run but w/ 991ft EG! We didn't know the little track field opened from 6pm so I run outside of the big track arena (my daughter was smarter than me)!

In all I ran 18/23 days in this trip to #Taiwan, totaling 96.13mi! My daughter ran slightly less at 85+mi. We ran in Taipei, #Tainan, #Kaohsiung, and #Kinmen, including a #10K race! I also crossed 2,500mi this year (now at 2,518.6), 100+mi over my 2,400mi goal!

September #running recap: compared to August I have 152.2 → 178.1mi (194.6 w/ walking), EG 1,206 → 1,835ft, 24 → 29hr running.

This was up slightly from August, but still not meeting the month's quota (200mi). Work took some of the running time but that's totally self-inflicted. 😛 My VO2Max via #AppleWatch also reached new high at 53.7!

I'm at 2,010.6 of yearly goal 2,400mi, 215.5 ahead. My next marathon #race is in 12 days — last chance to #BQ this year! Onward!

2025-09-29T14:35:47Z

Safer mileage building strategies:
- Spread extra mileage across multiple runs, not just the long run.
- Add small increments to easy runs, warmups, and cooldowns.
- Progress long runs in baseline increments every other week.
- Balance distance increases with lower overall intensity that week.
- Don’t increase mileage and intensity at the same time.
- Never “make up” lost mileage after a missed week.

I would suggest to pick a brand to boycott/support instead of boycotting anything from a US company.
- US is a big country, and blanket boycotting doesn’t help as much to put things back on track.
- There are non-US companies that are arguably also worth consideration, if we look at how they contribute to different political parties in US.

I’d suggest to look at https://www.goodsuniteus.com (they have free apps for both iOS and Android too). There is a “shoes” category.

Today I ran #TunnelVision #marathon #race as my 28th marathon since 2023. The official results are not out yet, but my watch recorded time 3:39:45, pace 8'23"/mi with -2,036 ft elevation drop (all-downhill).

Compared to the same race last year (time 3:46:13), I did improve ~6.5min. But this is far from my BQ target (3:20), and is actually slower than my Mill Town marathon race this April (chip time 3:24:01), which has EG ~800ft!

So, what went wrong?

After that I followed #ChatGPT coach's plan and ran an easy 2mi with 15s strides x 4 on Snoqualmie Valley Trail: lap pace range 5’36” -- 6'18”/mi. Other than minor ear/throat infection, everything seems fine!

One surprise: I don't know if it's the new watchOS26 beta or my tapering this week, I scored a personal record VO2Max today: 52.1!

Wish me luck tomorrow!

I was practicing #breathing, alternating between in*3+out*2 and in*2+out*1. Notes:

* It took me 4mi to get the hang of it because I was used to even ins and outs.
* At times my mind made up a 5-note melody for the first pattern: A-A-E-C-D. Seems my mind us using pitch to denote intensity of each breath.

So I ran 222 laps around the #UW water fountain with only 2 other runners as part of #Drumheller #marathon #race at 5:30am today, and Strava reported Marathon time 3:34:45 pace 8:11/mi.

A year ago I ran 3:38:57 pace 8:21/mi, so just 4min faster, but my avg HR dropped from 161 last year to just 147bpm!

The weather was also much nicer last year -- cloudy w/ 7F-lower temperature, and this year we got all sun w/o any cloud!

“…routinely running long distances raises the risk of certain long-term health problems, most notably cardiovascular ones. A 2020 review found endurance athletes are especially prone to ventricular arrhythmia, a type of abnormal heartbeat, and that middle-aged male athletes have more calcium deposits in their hearts, …, compared with non‑athletes.”

Hm… maybe it’s time to dial back a bit?

“The study revealed that #AI #chatbots actually created new #job tasks for 8.4 percent of workers, including some who did not use the tools themselves, offsetting potential time savings. For example, many teachers now spend time detecting whether students use #ChatGPT for homework, while other workers review AI output quality or attempt to craft effective prompts.”

#Running April recap compared to March: 228.6 → 200.4mi (217.3 w/ walking), EG 4,768 → 4,242ft, & 28hr running.

This was only 0.4mi above my monthly 200mi goal, due to the tapering and recovery around #MillTown #Marathon race. But I did refresh two #PRs from that race: marathon 3:25:52 (Strava) and 15K 1:09:25! I also ran two marathons this month.

I'm at 963.4 of yearly goal 2,400mi, 174.4 ahead. The next full marathon race is due in June (https://raceconditionrunning.com/drumheller-marathon-25/). Onward!

#MillTown #Marathon #race is done today! My chip time was 3:24:01 pace 7'47"/mi, and was 9th place out of 130, and the first in my age/gender division! I ran this same course last year as my first-ever marathon race, and this time I shaved off 27 minutes!

Oh yes, but only when they don't make "music" on my house. 🙂

A month ago we're puzzled in the early morning about some noise coming from our rooftop, like something striking repeatedly the metal part of our chimneys. I even recorded it to send to knowledgeable friends (attached). Turned out it's likely to be a male woodpecker making music on the metal chimneys. I guess it's springtime after all.

Decided to liberate myself today: 7.18mi easy run + strong finish from west Lake Union to Elliott Bay! Pace 8'59”/mi, ended at 7'35"/mi. 95% Z2 or under.

Sunny with clouds, felt like 53F, wind 4.5mph NW. Beautiful day!

"World's Fastest 10K" is mine too, for today! Chip time was 43:56.1, and Strava recorded 44:16 (PR)! I placed 15th of 172, 11th of 74 males, and 2nd in my age/gender division!

GAP was 7'13"/mi, so my finish time would've been 44:45 if this were not a downslope course. Still within my 45min goal!

Weather was bad in the beginning: felt like 36F with rain and wind 9.5mph. But rain stopped after the race started!

2025-03-16T03:08:51Z

Cold and windy in today's #ParkRun (26F wind 16.5mph), but I got my fastest 5K time this year: 21:29! This actually beats my finish-time PR last November on pace: 6'55"/mi vs 7'/mi!

This is also my first time racing with Alphafly 3! Some notes:

1. They are squeaky! But less squeaky as I go faster.
2. Easier to balance with faster pace.
3. At faster pace I feel like they are running my legs, not the other way around! Good if you have strong legs/heart to keep it up!

Another #Yasso800 day: 6 laps with predicted #marathon finish time 3:27 -- 4 minutes slower than a few week ago, and I didn't even do 8 laps! I felt easily tired today: HR is fine, but legs got tired faster, and breathing felt heavier.

About max HR: I finally revised it down from 175 to 170 -- it's been months now since I saw my HR went above 170. In fact I'm having trouble making it go faster than 165! I hope it means I'm more efficient now other than a simple reason -- aging... 😔

It was clear sky with sun felt almost like summer: it was 61F and I could certainly feel the heat! I brought 1L electrolyte, 2 gels and one energy bar, and I consumed them all.

I finished the run in time, showered in Fruit Park gym, and headed straight to airport. Zzz on the plane home!

This #LongRunSunday I only had ~3 hours before sunset in #Cupertino, so I went as far as I could on Rancho San Antonio trails: 9.67 miles with 1,545ft EG, time 1:42:34, pace 10'36"/mi. But only ~6mi was on trails -- the rest was just running back to hotel!
