Tree.fm plays the sounds of forests, recorded by people who’ve visited them. The website also displays a beautiful full screen photo for each forest soundtrack you play. — MF

Wherever I am headed to, I always buy the latest edition of a good guidebook. It’s a cheap bargain compared to the cost of the trip. I use all the brands, RoughGuides, Moon, Brandt, Fodors, and many independents, but by far the consistently best guides are Lonely Planet. Crammed with info, maps, prices, all dutifully updated frequently. I think they do the best job or orientation, organizing, and serving angles of interests, If you go to the Lonely Planet website and look up your destination, they’ll tell you when the next edition is due so you can judge whether you want to wait. — KK

I recently bought a 3-disc CD set and needed to rip it to iTunes but my laptop doesn’t have a CD/DVD drive. I bought this tiny USB-powered CD/DVD reader-writer for under $20. I plugged it in my laptop and inserted a CD. iTunes opened automatically, I clicked a button and the songs downloaded to my computer without a hitch. I’m sure it will come in handy for watching my old DVDs, too. — MF

When I need to know the name of a font (say so I can seek it out and use it myself), I snap a screen shot of it and place it in this free website, WhatTheFont, which usually identifies it. — KK

I get my eyes checked every year, but haven’t had my hearing tested since I was in high school. Soundly.com has a free 5-minute hearing test that was designed by audiologists and sound engineers. It’s for educational purposes only, but a good place to start nonetheless. I took the test and it reported back I have mild hearing loss which is not at all surprising or alarming. It just motivates me to mention this at my next physical. — CD

As baking season begins again, I am reminded of how fantastic our Classic KitchenAid Stand Mixer is after 25 years of use. I believe it could easily go another 25 years. There are mini and maxi versions and scores of competitors and imitators, but KitchenAid is still making this same “K” design – which is built like a tank – since the 1930s. They are so rugged there is a healthy aftermarket for used ones on Craigslist. — KK

I’m learning a lot from scrolling through this list of common misconceptions. These are concise summaries that are linked to longer articles on Wikipedia. I like that they are worded as a correction, with the misconceptions implied. I’m relieved to dispel the misconception that the pyramids of Egypt were built by slave labor. I’ve also learned that dogs sweat mainly through their footpads and the Pacific Tree Frog is the only frog species that actually makes the “ribbit” sound. — CD

There are few newsletters I read as soon as they arrive in my inbox. Coco’s Variety is one of them. It chronicles the obsessions of a Los Angeles used bicycle shop owner. He writes about collecting antiques, restoring old cars, cooking, garage sales, flea markets, good books, good music, and good living. His perspective is inspiring. — MF

The Mind Thing is a 1961 science fiction horror novel by Fredric Brown. The first time I read it was over 30 years ago when I bought this used copy for 75 cents. Recently, I reread it and recommend it to anyone who enjoys Invasion of the Body Snatchers and Twilight Zone. In the story, an alien hijacks animal brains (including people) and uses their bodies as puppets. It must kill the body it is inhabiting at the time in order to jump from one to another. At 150 pages, I found The Mind Thing to be an exciting, fast, and satisfying read. — MF

Here’s a cool visualizer of all the places that Anthony Bourdain has visited in his travels on Parts Unknown and No Reservations. I’m traveling to Cairo next month and someone suggested I go where ever Bourdain ate, so I googled and bookmarked places to check out from here. — CD

I giggled for an hour watching standup comedian Sheng Wang’s Netflix special, Sweet and Juicy. I love his uplifting and positive style, which is rare in comedy. He cracks jokes about enlightenment, except he is serious. And instead of long buildups to punchlines, he delivers an unending patter of quiet epiphanies. It’s laugh therapy! — KK

According to this Guardian article, “regular doses of awe may be vital to our wellbeing and make us nicer people.” The article includes a list of different ways to experience the shivery, goosebumpy feeling of awe, including attending live performances by skilled people, watching nature documentaries, and listening to music that gives you the chills. — MF

The Prepared is a free weekly newsletter about manufacturing, materials, engineering, infrastructure, factories, and the built world. It’s put out by hardware nerds. They also have a great cool tool review section on their website. The newsletter is insider talk about professionals making stuff for real. I look forward to it every week. —KK

Here’s a great jumping off point to learn about different types and approaches to psychotherapy. I have been hearing from friends about Family Systems Therapy and looked it up here. I also really appreciate this article on The Elements of Good Therapy, which should be empowering, non-pathologizing and collaborative. — CD

Consensus.app is a search engine that extracts, aggregates and distills findings from 200 million peer-reviewed scientific research papers to answer your questions. It’s still in beta, so there is disclaimer that the results are not meant to be taken as final truth, but more of a reflection of relevant research relating to your query. I love using other search engines besides Google whenever I can. Here’s a list of other interesting search engines we’ve recommended in the past. — CD

I just finished listening to a 5-hour podcast interview by Lex Fridman. Lex is an AI researcher who started interviewing colleagues in his field, and then kept expanding his reach and interests. He now interviews intellectuals and thinkers in many technical fields, from biology to cosmology to philosophy, usually at great length (many hours). Lex’s questions are often clumsy and awkward, but going long allows him to get deep, and often intimate. He seeks answers to hard questions. While he sometimes interviews famous pundits, he usually speaks with really interesting people you’ve never heard of. The payoff is that his Lex Fridman Podcast keeps me informed about “big questions” stuff. — KK

We think you’ll like our newest newsletter, Tools for Possibilities. Every Monday we’ll send you a one-pager with the best parts of my Cool Tools book, which is now out of print. This oversized book rounded up the best tools we knew about in 2013 and presented them by category. I called it a Catalog of Possibilities. Our succinct newsletter takes each category and selects the reviews for 2 to 4 tools in that category. It is basically a way to distill and re-distribute the deep, deep archive of the Cool Tools website, which has been reviewing tools daily since 2003. The information about the tools, whether they are still available or even still the very best, has NOT been updated. (They are just a search away.) We present this stream of tools – defined in its broadest sense as anything handy for an individual or small group – as an easy way to see what possibilities there exist if you want to make things happen. It’s brief and free. Sign up for Tools for Possibilities here. — KK

I like this visual reminder I came across on Reddit of “What I can control and what I can’t.” It reminds me to celebrate the wins — I no longer reactively say, “You make me feel this.” I used to have to correct myself to say, “When you do this, it makes me feel this.” But after years of practicing, it’s now become second nature to take responsibility for how I feel. — CD

I own three pairs of Roark Explorer Adventure pants. They dry quickly in my hotel room after being washed. They feature a side zipper pocket for cell phones and passports, as well as a hidden back zipper pocket for wallets. I was in Carcassonne last week and warned that pickpockets were active there, so I was glad to have my belongings secured. — MF

Clear caulking and clear hot glue are the norms. But caulking and glue also come in colors, like black. For instance black caulking and black hot glue are perfect for projects involving light seals, or when working with dark materials. Curiously, a black patch or seam will often disappear more than a clear one. — KK
