The #1 app on iPad is a calculator

When it comes to AI, it seems like the vast majority of people I talk to believe large language models (LLMs) are either going to surpass human intelligence any day now or are a crypto-scale boondoggle with zero real-world utility. Few people seem to land in-between.

Not a ton of nuance out there.

The truth is, there are tasks for which LLMs are already phenomenally helpful, and tasks for which today's LLMs will invariably waste your time and energy. I've been using ChatGPT, GitHub Copilot, and a dozen other generative AI tools since they launched and I've had to learn the hard way—unlike with web search engines, perhaps—that falling into the habit of immediately reaching for an LLM every single time I'm stuck is a recipe for frustratingly inconsistent results.

As B.F. Skinner taught us, if a tool is tremendously valuable 30% of the time and utterly useless the other 70%, we'll nevertheless keep coming back to it even if we know we're probably going to get nothing out of it. Fortunately, I've been able to drastically increase my success rate by developing a set of heuristics to determine whether an LLM is the right tool for the job before I start typing into a chat window. They're based on the grand unifying theory that language models produce fluent bullshit, which makes them the right tool for the job when you desire fluent output and don't mind inaccurate bullshit.

Generative AI is perhaps the fastest-moving innovation in the history of computing, so It goes without saying that that everything I suggest here may be very useful on June 9th, 2024, but will read as a total farce in the distant future of November 30th, 2024. That said, if you've been sleeping on using LLMs in your daily life up to this point and are looking to improve your mental model of how to best relate to them (as opposed to one-off pro-tips on how to accomplish specific tasks), I hope you'll find this post useful.

So here they are, three simple rules to live by.

To be continued…

Every year, Japan's convenience stores and packaged food companies attempt to sate the nation's voracious appetite for novelty goods by releasing a slew of products that you or I might consider weird as fuck.

I just spent a month there, and snapped a photo of my favorite head scratchers:

If it's not clear what you're looking at, here's a brief rundown of what each of these is (or purports to be):

1. Candy that's shaped, sized, and flavored like peanuts and which features peanut-like crunchiness. (Why not just eat peanuts, though?)
2. "Chiizu-tara", a common Japanese snack that sandwiches cheese with fish paste. This one is co-branded with a popular delivery pizza chain and flavored like spicy sausage
3. Gummies colored and shaped as sliced bell peppers (always referred to as paprika in Japanese), flavored as savory consommé broth, with vegetable content equivalent to one serving of lettuce
4. "Delicious tomato" flavored alcoholic chuuhai cocktail in a can, exclusive to Japan's northern Touhoku region
5. Gummies shaped like salmon nigiri, where the salmon pieces are orange-flavored and the rice is yogurt-flavored
6. Another alcoholic chuuhai, this one flavored after Suntory's Dekavita C beverage, a long-running vitamin C, B, niacin, and amino acids supplement. Get healthy and drunk in one step!
7. Toma'nade, which is like a cursed Arnold Palmer and contains a full tomato but an unspecified amount of lemons
8. Gummies shaped like bisected soft-boiled eggs. They're flavored like white grapes, and the package reassures the consumer that they are not egg flavored
9. Jelly sparkling grape drink. You are meant to shake it ten times and then let the juicy-jelly find its way down your gullet, I guess
10. French fry and hamburger flavored potato chips are all the rage this year (I found at least three kinds of each), but far-and-away, the winner was this one modeled after Wendy's limited edition "Wild Rock" burger from 2017, which featured two burger patties in lieu of buns (like a beef equivalent to KFC's Double Down). Again, this isn't that, these are potato chips modeled after an off-brand hypothetical burger that looks just like the Wendy's Wild Rock burger. Also, to be clear, the potato chips are neither a low-carb or high-protein snack, they are simply meant to have a taste that's evocative of burger meat. I can't stress that enough

Humane, of overpriced AI tchotchke and parting-foolish-VCs-with-their-money fame:

Our investigation determined that the battery supplier was no longer meeting our quality standards and that there is a potential that certain battery cells supplied by this vendor may pose a fire safety risk.

I would normally be worried about people's safety here, but I'm pretty confident that all of Humane's customers had already stopped using it months ago.

One of the mysteries of traveling Japan is that their domestic business hotels often deliver a higher level of service and amenities than comparable Western chains, even so-called "luxury" brands—all while charging a fraction of the price.

To illustrate, I've mostly been staying at Dormy Inn and their higher-end Nono brand for most of the last two weeks.

When you stay at a Dormy Inn, these services are more-or-less always included with your stay:

• All the typical hotel amenities you'd expect (wifi, etc.)
• Access to a large public bath, typically featuring a sauna, an outdoor bath (露天風呂), and a cold plunge—moreover, the baths are typically genuine certified onsens when the hotel resides in an area with hot springs nearby
• Free use of their laundry machines and dirt-cheap (¥100 per 20 minutes) electric dryers
• "Roomwear" – in lieu of proper yukata, shirts and pants suitable for traipsing back and forth to the baths; especially handy when you're doing laundry
• Free ice pops at night and yakult-style probiotic yogurt drinks every morning
• Free coffee machines, and often soft drinks as well
• Free "yonaka" late-night ramen (9:30pm - 11pm)
• Mini libraries with comics and novels
• Some properties feature complimentary massage chairs
• Each room's fridge comes pre-loaded with bottled water and a seasonal sweet
• Local flair. For example, Aomori's Dormy Inn features free local apple juice (probably the best apple juice I've ever had, and I'm from Michigan), as well as beautiful Nebuta-style mini-floats lining its bathing floor

The Nono chain goes a step further by being completely floored with tatami mats, requiring guests to check their shoes in lockers at the hotel entrance. It's actually really nice in practice, and creates a very relaxed atmosphere throughout the hotel.

The price for all these amenities? Usually about $70 USD. Here's the total damage for all my Dormy stays this month:

• Matsue (Nono) for a massive room with three beds (17,717円 / $112.66)
• Kanazawa (9,850円 / $62.63)
• Toyama (Nono) (11,000円 / $69.95)
• Niigata (10,150円 / $64.54)
• Akita (10,750円 / $68.36)
• Aomori (11,150円 / $70.90)
• Morioka (11,150円 / $70.90)
• Kawasaki (12,150円 / $77.26)

That's $597.2 for 8 nights at a fantastic hotel loaded chock full of amenities and which probably saved me $50 in coin laundry and coffee alone. For comparison, the cheapest room in a Red Roof Inn in Orlando, Florida tonight is $112.36, just 30¢ cheaper than the downright luxurious Nono property in Matsue.

Several Japanese hotel chains offer (to an American) an unheard level of value, and I'm mad nobody told me that Dormy Inn kicked so much ass until I stumbled upon the Kobe property last spring. So here you go, someone is telling you.

Anyway, hopefully this is some news you can use.

I'm happy to share that I'll be speaking at Rails World 2024. Everything I heard about last year's event was overwhelmingly positive, and my interactions with Amanda give me every confidence that this year's event in Toronto will be great, as well. Japan's RubyKaigi—which has grown to 1400 attendees and attracted dozens of corporate sponsors—has set a high bar for any conference that aims to blend community-building, professional development, and in-person collaboration to push a technology forward, but every indication suggests Rails World is on the right track.

My topic? Glad you asked.

In keeping with the "one-person framework" motif, I'm calling it "The Empowered Programmer", as a sort of sequel to my 2019 presentation, The Selfish Programmer. I'll be talking about the Rails 7 app I've been building this year, in support of my wife's eponymous Better with Becky business.

A few themes that might emerge:

• The value of proving out the app's basic plumbing with a lower stakes proof-of-concept, so as to avoid packing one's most naive, unconventional code into its most important "MVP" features (in this case, by building Beckygram before breaking ground on the more important strength-training system)

• Why to adopt and how to get the most out of relatively recent Rails-ecosystem tools like Hotwire, Active Storage, and Solid Queue—many teams skip omakase stack stuff out of habit or because they're upgrading an older app, but staying on the rails has greatly accelerated my productivity as a solo developer

• The various (mis-)adventures I've had with GPT-4 as my only pairing partner

• How nice it is to not have React or Webpack anywhere in my codebase. Seriously, Stimulus and Turbo really feel like the "JavaScript sprinkles" we should have had all along, and the amount of pain they can spare you from trying to balance a single-page JavaScript app with a Rails backend is profound

• Plenty of other takes, served hot
