jmccaf··on MTG Bench: Testing how well LLMs can play Magic
Awesome ! Does this use https://mage-bench.com/ , or is it a separate project? I ran 4 local models in a tournament recently with mage-bench on an RTX 5090 ; Qwen 3.6 27B won narrowly over Gemma 4 .
jmccaf··on The future of everything is lies, I guess: Where do we go from here?
If you push a change, or you approve, you're responsible for the change and its effects later. Regardless of size. If change is too big, tell your teammates its too big to review and to refactor to bite-size with their great coding agents. Use AI models also for review of large changes, consider a checklist . Setup CI and integration tests (also can be AI assisted)
jmccaf··on U.S. to suspend the Jones Act in a bid to curb oil prices
I think this is bad strategic precedent for the USA, to save few bucks now. I believe in the Jones Acts original purpose, to protect the US Merchant Marine , for that industry's necessity during wartime
jmccaf··on Ada 2022
My workplace uses Ada SPARK for high-integrity automotive software, ported from C or C++. IIUC, the contracts and static proofs can replace some activities like isolated unit tests for C++ .

jmccaf··on AGI fantasy is a blocker to actual engineering
I think the water use arguments are relevant, particularly in regions of the world and US (CA) where potable water is scarce, but land and electricity are available .

NYT article gift link where people reported wells ran dry after data centers moved in. : 'From Mexico to Ireland, Fury Mounts Over a Global A.I. Frenzy' https://www.nytimes.com/2025/10/20/technology/ai-data-center...

From https://www.eesi.org/articles/view/data-centers-and-water-co... , I understand there are two types of cooling with water in DCs, open-loop that's simple but water-intensive, and closed-loop that's expensive but efficient.

>> This can be achieved through air cooling using water evaporation, which is an open-loop and more water-intensive method, or through server liquid cooling.

For traceability, cut diamonds are laser enscribed with serial number or makers mark visible by inspection with jewelers magnifying loupe.
jmccaf··on Origins of the Sicilian Mafia: The Market for Lemons (2017)
Article mentions the climate and growing conditions for citrus are specific so there were few locations where citrus was produced that were integrated to world trade; mild temperatures above freezing, irrigation, and rich soil. The article mentions large lemon exports from Sicily all the way to New York; and California wasn't a united state or developed market producer of fruit at this time.
jmccaf··on ‘No way out’: how video games use tricks from gambling to attract big spenders
The pachinko parlor "special prize" token, with a separate business next door to buy the token for cash, is the analog example of this conversion.
jmccaf··on Tesla directors agree to return $735M following claims they were overpaid
Yes, 'director' is job title in engineering management. Generally Ranks above 'manager' and below vice-president
jmccaf··on Goodbye, San Francisco
Also, in my learning 'street smarts' as an adult , one lesson tougher people including my wife have taught me , is to trust your gut instincts if you are in a neighborhood or situation and you feel unsafe.
jmccaf··on Westfield Pulling Out of Downtown SF
Valley Fair did complete a major renovation about by December 2022, and I agree that is a glaring omission in Westfield's PR statement.

It doesn't refute that Westfield Valley Fair is booming and bustling, since the renovation. I live in Santa Clara like 1 mile from Valley Fair, and visit frequently to shop for gifts. Subtly, completing the renovation improved the pedestrian circulation in the mall, there aren't dead-end wings now.

Valley Fair is very busy, like many people there on any weekend and most evenings, but not inconveniently so. Busier than any other commercial venue I've seen post-pandemic. On weekends some restaurants there have long lines that I don't understand to wait in, I'll go eat later at a neighborhood restaurant.

The slow driving traffic that I've encountered is when I leave at 9pm when the mall closes and there is mass exit. I could the 1 mile too, or bike or scooter, but I often drive.

jmccaf··on When markets melt down, these traders cash in
I'm less familiar with put and call options , compared to common shares and selling short; But one of the challenges to sell short, compared to buying long, is that your upside is limited and liability unlimited. Whereas the inverse for common stock, upside is unlimited and liability is limited. If you place 176 bets and win big 8, I think will be more successful buying long , like the venture capital model.
jmccaf··on I wish Asciidoc was more popular
My work adopted ReStructured Text and Sphinx for large volume of technical documentation, similar system to AsciiDoc .
jmccaf··on Is wine fake?
As a Finger Lakes, NY alumnus, I appreciate the respectful comparison to our regional vintage. Reportedly the moderated microclimate of the region due to lakes, and the glacial soil terroir are good combination. Cornells agricultural school also researches experimental varietals.

My NY family puts as much pride in the local apples and the summer sweet corn as the regional wine.

jmccaf··on Inflation causing higher prices at the local bakery
What you described sounds much better than one of the default alternatives, which is : the business would be closed with 0 locations.
jmccaf··on Elon’s Out
Most of the middle class in America has a salary, or at least a paycheck, but distressing little cash saved. But they do pay the taxes that pay the bills.

jmccaf··on Adding unusable RAM for tax reasons
PT cruiser is an example of the opposite, which sought truck classification: https://www.brakeandfrontend.com/tech-spec-retro-work-servic...

Chrysler specifically designed the PT Cruiser to fit the NHTSA criteria for a light truck in order to bring the average fuel efficiency of the company’s light truck fleet into compliance with CAFE standards.

jmccaf··on Chip shortage leads carmaker Opel to shut German plant until 2022
'Rear Visibility' is required in new cars in US by FMVSS 111. Test procedure mandates field of view to rear of vehicles during backing, that are practical to satisfy with cameras. mirrors would require like a periscope to satisfy.
jmccaf··on 7-11 is opening 500 EV charging stations by the end of 2022
I love more charging stations, but I agree with this skepticism, 7-11 tend to be very quick stops ? If 7-11 builds chargers at my nearest location, I'll occupy them happily and walk home while charging. And perhaps I'll enter 7-11 on the drop-off or pick-up trip ?

I have a plug-in hybrid (Volt) and live in an apartment complex without chargers, and I use the abundant shopping mall chargers at Valley Fair mall in San Jose, CA as you describe. I live close enough to walk home 1 mile from the mall, so I'll drop car off, then go into mall to pickup a meal at the nice food court or browse around. Probably as 7-11 hopes: I'll readily spend $10-$15 on food, while charging $5.

My unique fit here is that Valley Fair is an urban mall: it's close to my apartment in healthy walking distance, and it has dense multi-level parking structures, so I'm not walking out and back through a vast mall parking lot.

Movie theaters in malls map well to charging stations because of the 2 hour duration you are inside, for when people go inside movie theaters again ($AMC?) Offices and workplace charging work well for me too (when not WFH)

There is a joke about the irregular English conjugation of the verb "invest":

- I invest

- you trade

- they speculate

jmccaf··on Colombia is considering legalizing its cocaine industry
Not a rhetorical question. 1 concern with the growing cannabis industry in the united states is the limitations on banking and finance for cannabis.

The harmful side-effect of a state-legal cannabis industry but denied access to banking can lead to holding too much cash on hand and robberies like : https://www.mercurynews.com/2020/11/04/person-shot-by-police...

jmccaf··on Pigs are as smart as dogs. Why do we eat one and love the other?
Yes, those are important. Surprise to me that xylitol gum is toxic to pets too.
jmccaf··on Pigs are as smart as dogs. Why do we eat one and love the other?
Pigs are also a handy source of meat. They grow to a large mature size quickly, reproduce in large litters with an early sequel maturity, and (like dogs) can eat all type of food, like the las vegas pig farm on restaraunt leftovers https://www.agupdate.com/agriview/news/business/pigs-part-of...

Anecdote: my inlaws in Colorado 50 years ago used to grow potatoes for market and raise pigs for themselves. They showed me an enormous cast iron pot dug into an earthen stove where they'd cook potato "slop" for the pigs. To this day the family cooks with lard instead of oil.
