On a recent wedding party trip, a group of six of us easily split the costs of our stay, food, drinks, Ubers, and party favors using Splitwise. We created a group that allowed each of us to add our expenses individually, and the app handled all the calculations and cost-splitting for us. All that was left to do was for each person to settle up at the end of our trip. The app is free to use on iPhone, Android, and the web, and we managed just fine with the free version. — CD

A blog I am really digging is Brian Potter’s Construction Physics, which is self-described as “Essays about buildings, infrastructure, and industrial technology.” Sounds boring, but is thrilling, as Potter deep dives into our built environment. The territory is similar to the podcast 99%Invisible, but far more quantitative. I’ve found his investigations so interesting I am systematically reading through his back issues. — KK

A study found that smelling isopropyl alcohol pads was more effective than a common anti-nausea drug at reducing nausea in emergency department patients, with peak effect in just four minutes. I bought a box of 100 alcohol prep pads ($6) to keep in my wallet for emergencies. Just hold near your nose and inhale gently if needed. They're so slim I forget they're there, but I'll be glad to have them if nausea strikes. — MF

The best show in the Star Wars universe is the extended story running through Andor and Rogue One. Tight drama, no cartoon comedy, stunning alien worlds. Season 2 of Andor is now streaming (on Disney+) and it is even better than the first: incredibly intense and gripping. It’s a story about how resistance to fascism stumbles, and the sacrifices needed to prevail. The skill in building these worlds is stellar, with next-century levels of detail and immersion, way beyond the classic Star Wars films. Same universe, but for thinking adults. — KK

Found on Reddit, this guide to rewiring your brain emphasizes interrupting negative thought patterns, reframing perspectives, and, of course, mindfulness as techniques for mental transformation. There’s no step-by-step outline—and each of these 12 methods requires additional research for support—but I found the guide helpful as a reminder that our brains are transformable. All it takes is attention and intention when it comes to developing better habits. —CD

Merlin Mann's Wisdom Project is a collection of life lessons hosted as a text file on GitHub, delivered with Mann’s trademark humility and sharp wit.

Five pieces of wisdom:

• Write down the travel items you forgot to pack while you're still traveling.

• Sometimes in life, even though it's not your fault, it's still your problem.

• You are not obligated to have a strong opinion about everything.

• Never organize anything you should discard.

• If an item is especially precious or valuable to you, never set it down anyplace that you wouldn't want it to be overnight.

I wasted a lot of money on sticky tape lint rollers until discovering the Scotch-Brite Lint Brush. The angled fibers grab pet hair and lint more effectively than disposable rollers, especially on wool and furniture. What I like most is never having to buy refills — swipe your hand across the brush in the opposite direction to clean it off and it’s ready to use again. — MF

This article lists 20 verification tools for combating misinformation. Included are fact-checking sites like Snopes and Google’s Fact Check Explorer, as well as reverse image search engines, identity verification sites, and AI detection tools. While this list is intended for journalists, these resources are useful for anyone who wants to critically evaluate what they read or find online. — CD

Two ChatGPT tips: For a few minutes’ entertainment, let ChatGPT play 20 Questions. It is very hard to stump it. Just tell it you want to play 20 questions and it will usually guess your most obscure thing. Fun for kids. It can also play the other side. If you are an active user of ChatGPT, ask it to summarize your blind spots. It will be spot on, and most people find the succinct answer useful in its clarity. — KK

The free Adobe Scan Mobile App converts physical documents into searchable, editable PDFs. It’s faster and easier to use than Apple Notes' built-in scanner. It automatically detects document edges, corrects perspective, and improves text clarity. The OCR is accurate, letting you extract and edit text from scans instantly. I recently digitized a 50-page puzzle book in minutes using the high-speed scanning feature — just flip through pages and it captures each spread automatically, then splits them into individual pages. I’m using it to digitize snapshots, too. It straightens, color corrects, and crops the images, then saves them to my photo library. — MF

The next health frontier will be personal air quality; what are you breathing? The best measurable proxy we have right now is the level of CO2 in the air. The more CO2 present, the more likely it is full of the exhalations of others, and the greater chance of infectious agents. The small, lightest CO2 monitor is AirSpot ($144), which is smaller than the size of a thumb drive, and will give you instant CO2 levels. I carry it in my pocket when travelling; if the levels get high, I can choose to mask, or exit if possible. (The highest level I’ve seen so far is in the waiting room at the DMV.) — KK

One Task X is a simple task list that forces you to prioritize one thing at a time. You’re only allowed to have one “Today” task, and once it’s completed, you can drag another task into the box. Everything is stored in your browser, so there’s no sign-up or login needed—you can simply close the tab and return to it later. — CD

Andrej Karpathy's guide to digital hygiene has practical steps for protecting your privacy and security. Here are the essentials: Use a password manager (like 1Password) to create unique strong passwords for every service; get a hardware security key (like YubiKey) as your second factor authentication instead of text messages; and use Privacy.com to create credit card numbers that are locked to one specific merchant and can’t be used elsewhere, preventing unauthorized charges. — MF

Many people are having trouble wrapping their heads around the fact that global depopulation and not overpopulation is our challenge. The childless trend has been underway for 50 years but has accelerated dramatically recently. We are at the cusp of deaths outnumbering births on the planet, with no change in sight. I recommend this very, very long New Yorker article – “The End of Children” – as the very best introduction and explainer. It focuses on particular programs, people, and events in South Korea, which is leading the world in depopulation, much faster than the Japanese. The piece is beautifully written, expertly reported, and informed. I think everyone should read it; paste the article url link into 12FT to read it in full. — KK

This two-part talk, How to Navigate the Weirdness by Erik Davis, gave me such great comfort and clarity on how to ground myself in the complexities of our current societal consciousness. The intention behind these talks is to honestly assess the present moment and share navigational tools for sanity, sense-making, and creative engagement. Davis gives historical context and talks about the transformative cultural shifts that have led us to this point, while also addressing the psychological impacts of media saturation, among other things. His strategies emphasize flexibility, mindfulness, and critical thinking. Here is part one and part two, and here is some of his advice (paraphrased):

• Ground yourself in physical sensations and direct experiences to counterbalance the effects of media saturation and overwhelming information.

• Use foxhole or gallows humor as a tool for resilience—find connection and levity even in difficult situations.

• Embrace an "emotional remix," allowing opposite emotions like grief and joy to coexist, fostering a flexible emotional state.

• Practice situational pluralism by recognizing that multiple valid frameworks exist for interpreting reality.

• Deepen your capacity to embrace uncertainty, mystery, and doubt without searching for fact or reason—not everything fits into a fixed narrative.

I love multi-day walks, but not hefting a loaded backpack the whole way. The solution is to have my luggage bag forwarded each day, so I only walk with a tiny daypack. This liberation is heavenly, and makes me glad to walk a week or more. Luckily there are outfitters that will arrange luggage forwarding in great places to walk in the countrysides of Europe and Asia. There are no guides; you pick the route you want, and the dates you want. They arrange modest lodging, the luggage forwarding, and then give you a map on your phone. The fees are very reasonable, not much more than the lodging itself. For example, last week I used MacsAdventures to help me walk the last 100km of the El Camino de Santiago in Spain. I’ve used the same outfitter to walk several self-guided week-long rambles in the Cotswolds, England. The arrangements and luggage pickups were flawless. — KK

In Kevin Rose’s recent newsletter, he shares the results of his semi-annual survey of Favorite Things. With more than 27,000 votes across 24 categories, the results paint a clear picture of the top tools people are favoring right now. Kevin runs this survey to track the rapidly evolving AI landscape and keep his community informed on emerging trends and products. Like the results reflect, I still use most Apple and Google products for things like email, calendar, and browser, but I’ve permanently moved on from Google Search to a paid Perplexity plan, and I can’t imagine ever going back. — CD

These tiny Syntech USB-C to USB-A adapters let me connect my older USB devices to my newer laptops. The pack comes with two adapters that plug into the computer's USB port. — MF

Kickstarter uses a clever financing model where every backer’s money is returned if the full funding goal is not met. But this innovation is only one of many dozens of possible funding models, and dozen more ways of collaborating, or governing projects. Allo Mechanisms is a handy gallery of 60 different possible “capital allotment” mechanisms, already invented, that might work for your particular needs. Some of them already have implementations. — KK

Tv.garden lets you spin a globe and watch live TV streams from around the world — no subscription needed. While channel surfing, I got caught up in watching Christian music videos in Senegal, Algerian news, and TV psychic readings in Bulgaria. It’s utterly captivating and transportive. — CD
