Searchable Recomendo
We made a searchable, inexpensive version of our Recomendo book. This PDF (in glorious full-color!) is only $1.99, and available internationally. Download, browse, and search through 550 great recommendations. — KK

Newsletter App
I’ve been using the Stoop app to discover and read new newsletters. It’s great to have them all in one place where I can let them pile up and read when I have the time. I’m really enjoying the Clearer Thinking newsletter, which offers tools for better decision-making. You can also find Recomendo on there! — CD

If You High (and even if you aren't)
The ifyouhigh Instagram account has 3.4 million followers, but I recently stumbled on it and am hooked. It’s an endless scroll of strange and beautiful short videos of natural phenomena, machinery in motion, slo-mo, time-lapse, art, and other “Whoa dude!” moments that you don’t need to be high to appreciate. (Photo of Moonlit fog waves at Mount Tam above) — MF

Typeset in the Future
I’m spending hours studying this coffee-table book celebrating the typography and design used in science fiction movies. What do we see on screens “in the future”? More broadly, this dense picture book, Typeset in the Future, is a roundabout way to examine where the interface design of technology is headed. — KK

The Alien Exercise
In Jen Sincero’s book, You Are a Badass, she describes the Alien Exercise for rebooting yourself and getting some clarity. Imagine you are an alien and you’ve just landed on Earth — into your body and life. Take notice of all the connections, opportunities, skills, possessions and people who love you and can help you. What would you do and how would you feel? I think this is great for brainstorming projects, ideas and new ways to enjoy your day-to-day life. — CD

Cheapest Lightning Cables
Lightning charging cables are expensive and seem to fray quickly. Micro USB cables, on the other hand, are dirt cheap and seem to last forever. I bought a 10-pack of adapters that convert a Micro USB plug into a Lighting plug. The price for all 10 was $7, about half the price of a single Lightning Cable. I tested them, and there were no duds in the pack. — MF

Digital Recomendo

The Cool Tools website focuses on handy, useful, proven tools. But a lot of great stuff that Mark and I come across are not really tools. We created the Recomendo email list for this purpose. Every Sunday we mail out 6 very brief recommendations of cool stuff: places we love, people to follow, great things to eat, good movies, fantastic podcasts, cool tips, short cuts, favorite items, and many other suggestions. This newsletter, Recomendo, is free and has over 20,000 subscribers. Sign up here.

Last year we took the best of our first two years' recommendations and put them into about 100-page book. The book (available on Amazon here) is made to be browsed. You can flip through it in any order and most folks will find something of interest on every spread. It is an easy read.

For the benefit of international fans, and for those who don't want paper books, we have created a digital version. It's a downloadable searchable PDF, in full color (the paper book is only B&W), weighs nothing, and is available instantly for only $1.99. We priced it so that anyone could afford it.

If you do get one, let us know how you like this format. (We don't have plans for a Kindle version yet, but maybe in the future.)

Dual scale tape measures/Gmail tips/Papier

Dual scale tape measures
In my ongoing campaign to make myself literate in metric (used everywhere in the world except the US), as much as possible I try to measure only in metric. I got a Komelon dual scale measuring tape (both metric and inches on one side) and after a month or so, I can think in metric. I really like Komelon measuring tapes because they are inexpensive but high quality. They have four in different sizes in dual scale from 3.5m/12ft for only $5, to a 9m/30ft for $8.50. The 9-meter one is big in the hand but an incredible bargain; however their 5-meter is probably a good size for general use.  — KK

Gmail tips
Gizmodo has a useful article on several ways to improve your Gmail experience. One example: my address is I can sign up for newsletters by using and then filter the email to a “newsletter” label. —  MF

Take notes in your browser
My current favorite chrome extension for optimizing a new tab is Papier. It’s just one single note page. This is perfect for taking quick notes without minimizing or closing your browser. Everything you type autosaves and syncs to Chrome. You can create lists with checkboxes, and there are even a few formatting and style options available. But I feel the simpler, the better. Right now I have saved a few lines to a poem I am working on, so that every time I open a new tab I’m reminded to stay inspired. — CD

Ocean-friendly sunscreen
Many sunscreens contain ingredients harmful to coral reefs. Hawaii announced a ban on sunscreens containing oxybenzone or octinoxate, which goes into effect in 2021. Our family switched to zinc oxide sunscreen, which doesn’t hurt coral reefs. We like Thinksport SPF 50+($10.25 per tube). — MF

Quickly access delete account pages
I began the year with a purging of accounts I no longer use like Facebook, Snapchat and LinkedIn. This Consumer Reports article has direct links to Delete Account pages for the major platforms. It spared me the hassle of  navigating through settings in search of a delete button. — CD

Best podcast episodes
I’ve been using these two lists of the “best podcast episodes from 2018,“ one from Vulture (10 picks), and one from IndieWire (50 picks), to listen to some great individual shows and to discover new podcasts to potentially subscribe to. — KK

Best Maker YouTube Channels/Temi/Listen Notes

Check out our new Recomendo book! 550 of the best recommendations from the past two years.

Best Maker YouTube Channels
Most of my discretionary media time is spent watching YouTube. I derive immense pleasure in finding out how things work and how to make and repair things. Over several years of watching all kinds of video, lousy and great, I’ve collected a bunch of channels for dependable high-quality content. In a long post on our blog Cool Tools, I review the top 30 YouTube informational channels that I subscribe to. (#1 on my list is Cody’s Lab.) — KK

Automatic transcripts
When doing interviews, I like to have a transcript of the conversation. This is useful for fans of podcasts, and for journalism. The best transcripts are done by humans, but I can get very cheap, very fast transcripts that are 90-95% accurate done by AI. (Depends on quality of recording and accents.) Temi will give me a transcript for 10 cents per minute of audio ($6/hr), delivered in about an hour turn-around. The Word doc or PDF output will have time stamps on it, making it easy to go back to find the actual audio for correction if needed. The Temi transcript is accurate enough to find key passages; with one listen-through I can quickly clean it up for public consumption. — KK

Podcast search engine
One way to find new podcasts is a website called Listen Notes — a search engine for almost all podcasts around the world. You can search for topics or a specific person and find related episodes. Or set alerts for keyword mentions. I’m not a daily podcast listener but every once in a while I’ll want to hear what people are saying about a certain news story or random topic on my mind, and in those cases Listen Notes is very useful. — CD

Respirator subscription
Anytime I go into the attic or near dust of any kind, I put on one of these 3M Cool Flow respirator masks. They are comfortable and they really help me from having a sneezing fit. My daughter uses them for her art projects. Amazon sells a 10 pack for $15, but I use Amazon’s Subscribe and Save and get a 10 pack sent to me every six months for $14. — MF

Easy background removal
This new website became an instant hit, and for good reason. Just upload any photo of a person, animal, or things, and it will erase everything in the background, replacing them with transparent pixels. It even works well when the person in the foreground has wispy or curly hair. — MF

Death quotes
A while back I recommended WeCroak. These are a few of my favorite quotes from the death reminder app.

“The only thing that isn’t worthless: to live this life out truthfully and rightly. And be patient with those who don’t.” — Marcus Aurelius
“We waste our energy and exhaust ourselves with the insistence that life be otherwise.” — Frank Ostaseski

“What do we live for, if it is not to make life less difficult for each other?” — George Eliot

“At some point in life the world’s beauty becomes enough. You don’t need to photograph, paint or even remember it. It is enough.” — Toni Morrison

“The cradle rocks above an abyss, and common sense tells us that our existence is but a brief crack of light between two eternities of darkness.” — Vladimir Nabokov

Audio Hijack Mac Application (Free Trial or $59 License)
Audio Hijack is like a router for audio inside your computer. You can record just about about any application’s audio output, or just record the system audio itself. If I want to grab some audio from a Youtube video I’ll just hit record and then hit play. It makes audio — not just what you have as files but any audio you can even play — available with a copy paste workflow.

Dyson V7 Cordless Vacuum Cleaner ($241)
I bought this vacuum last year and it’s the first consumer product since the iPhone that I’ve felt was so essential that I’d pay basically whatever they asked for it. Also, it wall mounts very securely in a way that I wished everything I hang up daily just clipped into place.

Apple TV ($180)
I use Airplay constantly. It really appeals to me as a technology and Apple TV is at the center of my living room. I’ve maintained a big stash of mp3s and movies for a long period of my life and have gone through a gazillion ways of playing them back, Apple TV is where I landed. I also like the app Beamer for sending movies to Apple TV. I’ve been sending my Apple TV sound to my Airpods recently after my family goes to sleep.

iFixIt Essential Electronics Toolkit ($20)
I was going to list this little synthesizer I have called the OP-1 but they’re not selling them right, so when mine broke I had to open it up and put in a replacement headphone jack. I bought this little toolkit from iFixIt that had the part and a handful of tools, the most useful of which is the “spudger.” I’ve ended up using this kit several times since then, including repairing a Minidisc player last week in order to get one audio file off a decade old Minidisc.

The 100 Best Business Books of All Time

There are ten thousand business books published each year and way over a hundred thousand in print. Most business books are worthless drivel, some are a good article fluffed out into a thin book, and maybe 100 out of those hundred thousand are worth reading. Out of those 100 best, only 10 might have something to say to you.

But how to find those few? Jack Covert and Todd Sattersten, two guys who sell biz books, seem to have read all of the ones in print, and they have done the world a favor by selecting the 100 best business books ever, and then packing summaries of them all into one meta-book. If all you want is their list, you can go to their website and check it out.

But their book is much better than a simple list, and their list is better than most. The two have reviewed, abstracted, and compared all the best 100 in the context of thousands of similar books, unlike say your average Amazon reviewer who may have only read one other business book in his or her life. You get context instead of content. Reading Covert and Sattersten's summaries of these classics is often better than reading the book itself, and the review is always useful in pointing you to the few books or authors you might actually want to read in full.

In addition to including the expected gems like Good to Great, The Effective Executive, and Purple Cow, the 100 Best list also includes many lesser-known titles, some of them oldies-but-goodies, like Up the Organization, The Innovator's Dilemma, and Flow. Not everything is new in business; the wisdom of the past is often surprisingly relevant.

Finally, this book itself is one of the best business books, and can be read alone as a pretty good education in business in its broadest sense, even if you don't read any of the references.

A couple of caveats. One, the authors has included one of my books (Out of Control) in their list, which tickles me greatly but might have warped my perspective. Two, they sell business books (at 800CeoRead) and so their book can be seen as a sales tool. On the other hand, the authors have great incentive to sell and include only the best, and so their list is pretty persuasive. Three, in a slip of bad design each of the 100 books featured on their website does not appear with the review as found in their book, but is featured with the standard publisher verbiage; the author's fantastic summaries and analysis are only found in their printed book. (They sell books, see?)

All in all, this is a great business resource at a modest price. If you took their list and read all 100 books you'd get a better MBA than any university would give you, at a fraction of the cost.

This is a cool 3-dimensional maze that is easy to get started and hard to finish. You need to steer a small metal ball along an ingenious obstacle course by rotating the clear plastic globe. There are 100 stations along the way, including some difficult topsy-turvy turns. All ages can get into it. We've found the puzzle to be extremely addictive to anyone who gets started. Because it's like a 3D video game without the electronics, the very physical nature of playing -- turning it this way and that -- is very satisfying. In addition, the maze is like a sculpture, the design of the route is geekily brilliant, and the elegance of the eternal return of the steel ball within the sphere is a stroke of genius. Perplexus has the glow of a work of art. It makes me happy just to pick it up.

The Art of Game Design

This is by far the best guide ever written for designing games. All kinds of games, simple and traditional, but of course video games, too. This fat book is packed with practical, comprehensive, imaginative, deep, and broad lessons. Every page contained amazing insights for me. The more I read and re-read, the more important I ranked this work. I now view it as not just about designing games, but one of the best guides for designing anything that demands complex interaction. My 13-year-old son, who, like most 13-year-olds, dreams of designing games, has been devouring its 470 pages, telling me, "You've got to read this, Dad!" It's that kind of book: You begin to imagine your life as a game, and how you might tweak its design. Author Jesse Schell offers 100 "lenses" through which you can view your game, and each one is a useful maxim for any assignment.

TheReviewIndex/Workflow music/Muscle map

Summarize Amazon reviews
TheReviewIndex finds recurring patterns in Amazon Reviews and then makes sense of it for you. It displays positive/negative ratings for things like “ease of use,” “quality,” “reliability,” and much more depending on the item. You can click through further to see snippets from user reviews pertaining to one particular aspect of the product. Right now the website only supports Electronics, Gadgets and Appliances. Worth bookmarking to make your shopping decisions a little easier. — CD

Workable flow music
When I am in the flow for work, headphones on, I like to put on any of the annual 2-hour tracks recorded by the DJ Tycho at Burning Man sunrise. Each set is upbeat, trancy, mellow. If you like this year’s Waypoint 2018 sunrise set, Tycho’s previous years are also available on his Soundcloud site. — KK

Muscle map
As a casual exerciser, I really appreciate this muscle chart from the DAREBEE website. It’s straightforward and I think, “hey, I can do that.” The website has other cool posters and printables to inspire you to workout. — CD

The best can opener
I bought the Kuhn Rikon can opener ($20) in 2011 and I still get excited every time I use it. It opens cans without leaving sharp edges. After opening hundreds of cans with it, it still never ceases to amaze me. — MF

End text formatting problems (OS X)
Here’s a beautiful life-changing tip for Mac users. Once you set these preferences, pasted text will be formatted like the destination, not the source. Why isn’t this the default setting? — MF

Geological modern art
Some of the best modern art on my walls are geological maps. These graphics are bright and cheerful while boasting scientific integrity. Geology from around the world can be used, but I favor geologically extreme places like this sample from Utah. For maximum of both art and science I highly recommend the Geologic Atlas of the Moon maps. Last printed in 1977, these Pop Art gems are now available as downloadable PDFs. (Crop and save as a jpeg.) I print mine on a 20 x 30 inch Costco poster board for $25. — KK

Recomendo Announcement

Every week for the past two years we briefly recommend 6 things to our friends. Sometimes we suggest tools, but most items aren’t tools. Rather we recommend stuff such as our favorite places to visit, things to watch or listen to, favorite stuff to eat, as well as tips for work or home, and techniques we’ve learned, quotes we like to remember, and so on. We email these 6 brief reviews in a free newsletter called Recomendo, and by now this one-pager is sent out every Sunday morning to almost 20,000 subscribers. If you want to get a feel for what we recommend, all the back issues are available here.



This autumn we collected, filtered and organized 550 of the best recommendations and put them into a book, called naturally enough, Recomendo. The book is 95 jam-packed pages. We’ve categorized the recommendations, grouping like with like. Having all the workflow tips, or household suggestions, or workshop tools, or travel recommendations all in one place is super handy. There’s an index and subject guide. Many of the items have an illustration. To make up for the fact that a book can’t have links, we’ve added QR codes, so you can instantly get a link with your phone. Everyone who has picked the book up has found something cool for them on the first page and they keep turning the pages for more. I think it’s the happiest book I’ve ever worked on.

Recomendo is available now from Amazon, for $9.99, with two-day Prime shipping. We will have a PDF version later for international fans. I genuinely believe it will make a great inexpensive gift for most people. It’s what I’m giving to friends this year. Order one for yourself and see if you agree.

The Book of Genesis Illustrated

As literature, the biblical book of Genesis has it all: sex, violence, angels, war, murder, heroes, incest, world-wide disasters, spooky mystery, and a timeless story. All it needed was illustrations by the comic genius R. Crumb and you'd have a underground manga hit. And that's what this book is. Crumb brilliantly did not alter or omit any words from the scriptural text, and even toned down his drawings to a PG-13 rating. But man, is this strong drink. It will burn your eyelashes. Like it must have done 2,000 years ago. Now you have absolutely no excuse not to read the first book of the Bible.

Spider And Web/Cheap new tools/Better Reddit browsing

Mysterious text adventure
I used to love the old Infocom text adventure games. They were interactive stories where you affected the outcome by making decisions and doing things as you moved around a world described in words only. A friend told me about a free web-based text adventure called Spider And Web and I am enthralled by it.  I don’t want to say anything about the plot. Just give it a try. — MF

Cheap new tools
It is easy to mock the importer Harbor Freight for their insanely cheap Chinese-made tools, but in fact I’ve had great success with the tools I’ve bought from them. I may only use them a few times a year, and for that frequency their quality is more than sufficient, and their self-proclaimed “ridiculously low prices” are in fact a tremendous bargain. Over the years I’ve bought a welder, a larger sanding wheel, a buffer, and recently a new compound miter saw for less than $100. – KK

Customize your Reddit feeds
The Reddit app allows me to switch between accounts pretty easily, so I created a few different usernames to group subreddits by themes. It makes browsing less overwhelming when I can focus on one thing I’m trying to accomplish. I have an account for all the subreddits that make me laugh (CrazyIdeasAnimalsBeingJerksCrappyDesign), one for learning new things (explainlikeimfivewhatisthisthingtodayilearned), and one for inspiration (CraftsMiniworldsonegoodsentence). I actually have a total of five accounts, it’s almost getting out of control, but still this method keeps me sane. — CD

Sampling books
Several power users of the Kindle turned me on to a great tip: load up your Kindle, or phone, with free sample chapters of any and all books you are interested in. Read the sample (usually the first) chapter and then decide if you want to buy the book. In fact, don’t buy any book until you’ve read the sample chapter. The “Send free sample” button is under the “Buy Now” button on the book’s Amazon page. — KK

Prevent hand pain
I can’t handwrite for long periods of time without some discomfort. These pencil grips are designed for kids and adults with arthritis, but they help me out a lot too. I bought a 6-pack for $11. — CD

Ultralight kneeling cushion
This cushion ($8) protects my knees anytime I have to work on anything close to the floor or the ground. I’ve had it since 2011 and am grateful to have it every time I use it. — MF

Forschner Victorinox Chef's Knife

A really great chef's knife is insanely sharp, yet retains its edge easily and feels well-balanced and welcoming in your hand. These days, a decent high-grade chef's knife can cost $100-$200. Several cooking publications, including Cook's Illustrated, recently tested a bargain $30 chef's knife that rated just about as good as the $100-plus knives. It's the Victorinox Chef's Knife; the one we use.

The Victorinox is a hybrid of a thin Japanese blade with a 15-degree edge (western knives have a 20-degree edge), but with the longer, broader blade of European knives. It is lightweight, nicely-balanced, and lethally-sharp. It has a comfortable, grippy handle that won't slip even when wet. There are five cooks in our household. This is the knife they all grab first. It may not be quite as super great as some of the other previously-reviewed chef's knives, but considering the price, it can't be beat.

Blank Playing Cards ($6)
"I am a firm believer in that you just never know where the next great game idea is going to come from, but you can be pretty sure that if you don't at least record it and prototype it somehow, it's going to be gone forever. So what these are, it's literally just a deck of cards, blank on the front, blank on the back. I travel around with these things everywhere I go, and just a bunch of Sharpies. And the basic idea is, any rough idea I have, I used to take all this time to meticulously document them and outline it and figure out the rule sets. And what I figured out is it's so much easier and so much more effective to go straight to paper prototype. And this is the absolutely best tool to do so. If you have a card game idea, jot down a bunch of cards and quickly see if it works. If that game needs dice, figure out how many sides you want that die to have and pull out that many cards and start drawing numbers on the cards … They're great to create characters, they create inventory items. Literally any game competition imaginable can be created with these things. So I carry them around with me everywhere I go."

Don’t Shoot the Dog ($14)
"Don't Shoot the Dog isn't actually about dog training. It's about positive reinforcement, and the psychological aspects of shaping behaviors. And what it all really comes down to in game design is picking a core game mechanic that you want, and a way that you want those players to behave around that game mechanic, and just molding it, reinforcing it, shaping it as much as you possibly can. … I love this book. I recommend it to all new game designers, not to learn how to train dogs or horses or any of the other animals in there, but basically to learn how to model behavior and reinforce the kinds of things you want to see your players perform and make them feel great about interacting with you and those behaviors."

Retracting Box Cutter ($7)
"In my workshop, I mostly deal with paper. I mostly am building paper prototypes all day, every day. And involved with that is a whole lot of cutting paper. And I was just making a mess. I was cutting my clothes and cutting my body with these stupid box cutters, 'cause I'm not a very organized, careful person. What this thing is is so simple. It's just a handle, and when you squeeze the handle, a small blade comes out, allowing you to cut paper or cardboard or whatever it is that you need to cut, and when you let go, the handle, the blade, retracts into the handle, making it a perfectly safe thing. So as I cut, and then stuff the thing in my pocket, suddenly I don't have to worry about tearing holes in my clothes or fingers or anything else. …It's super light. It's all made of plastic. It's actually not the sturdiest of devices, not to say the one I have has ever broken. But it has needed some repairs from time to time. It's super lightweight, and because of the price point every time I open a new workshop anywhere, I immediately buy about 10 of these things."

Retractable Charging Cable ($13)
"It's a Lightning cable. It's actually also a mini USB cable. … I travel a ton, and the problem I have with all cable organization is I'm just too lazy to adhere to it. The cases and the straps and all the things that I need to keep my cables organized, I end up abandoning. …So this solves that problem for me. What it is is a small plastic case, maybe about the size of four quarters in a stack. And it has the front and back ends of the cable poking out of it. You pull them, and suddenly, you have a two-foot long ... in this case, iPhone cable. Pull them again, and they're spring-loaded, so they retract back into the case. And what this does is I travel around with four of these things, and whatever adapters I need, and then just a USB brick that plugs into the wall and has four ports. So when I set up in any hotel, I plug all of these things in. I can charge all of my devices overnight. And then the next day, when I need to pack up, I literally, one fist, grab everything out of the wall, yank on both ends, they all retract into a single, very neat pile. I drop those into a pocket in my backpack, and I'm done."

Waterproof Notepad ($9)
"This is one of my favorite things. This is a waterproof notepad. I don't know why it is, but all my good ideas show up in the shower. I'm sure there's all kinds of writing about why, but I don't know. All I know is, every day, I take a shower and that's where all my best ideas pop into my head. And for whatever weirdo reason, when I step out of the shower, like waking up after a really lucid dream, I've just forgotten everything. So my solution was, I found this great super cheap waterproof notepad. It attaches to the wall or tiles of your shower via suction cup, and it ships with a totally standard #2 pencil, that also attaches via suction cup. And it's waterproof. So the pages have a slight waxy coating to them that ... They're hydrophobic, but the pencil markings work perfectly. So I jot down all my ideas in the shower."

Radical Markets/Trim/Deal with difficult emotions

Alternative economic ideas
Crazy ideas sometimes become everyday and obvious. No book I’ve read has had more crazy economic ideas than Radical Markets by Eric Posner and Glen Weyl. Their ideas — which rethink the idea of property and taxes — are intriguing, and even if wrong, might be productively wrong. It is dense reading, but exhilarating. — KK

Hire a negotiator to lower your bills
Trim is an online service that negotiates with your phone, cable TV, and Internet providers to reduce your monthly bill by asking for a discount. Sure, I could do this myself, but I’m happy to pay someone else a 33% commission on the money they save me.  So far they’ve successfully reduced my annual bills by $543.24. — MF

How to deal with difficult emotions
Practicing mindfulness is easier said than done. This chart breaks it down into six easy steps to make sense of your difficult emotions. I find that visualizing my emotion as a little tangled mess that lives outside of my body makes it less likely I will react impulsively. — CD

Cooperative tabletop game
Most board games have a winner and a bunch of losers. But there are a number of games where users must work with each other to achieve a goal. One of the best is cooperative games is Forbidden Island ($18). The goal of this attractively designed card and token game is to recover four life-saving treasures from an island before it sinks into the ocean, drowning all the players. Achieving victory requires players to formulate plans, agree on strategies, and make sacrifices. — MF

Inspiring livelihood documentary
Shorebreak is a fast 60 minute doc on Amazon Prime about this surfer who found a special niche in photography. His thing is standing at the scary point where giant waves break onto the beach while he photographs whatever crazy surfers are in the wave, before he ducks under the pummeling mountain. The doc is well done, his photography is stunning. But what I love is the lesson of focus, enthusiasm, mastery, and foolish individualization. His relentless enthusiasm, going back to the shorebreak day after day to see if he could make something new again and again, has improbably earned him a living doing this. What a treat! — KK

Below are some enlightening things I’ve read lately. — CD

“Loneliness is a sign you are in desperate need of yourself.” — Rupi Kaur

“When you say something unkind, when you do something in retaliation, your anger increases. You make the other person suffer, and they try hard to say or do something back to make you suffer, and get relief from their suffering. That is how conflict escalates.” — Thich Nhat Hanh, Taming the Tiger Within

“Your assumptions are your windows on the world. Scrub them off every once in a while, or the light won’t come in.” — Isaac Asimov

“The cost of a thing is the amount of what I will call life which is required to be exchanged for it, immediately or in the long run.” — Henry David Thoreau

“We’re all going to die, all of us, what a circus! That alone should make us love each other but it doesn’t. We are terrorized and flattened by trivialities, we are eaten up by nothing.” — Charles Bukowski

Insider industry news
I’ve become of a fan of Inside newsletters. Once a day I get a brief summary of what’s been reported in a narrow specialized field, like AI, or VR, or Space, or Robotics. Succinct, select, in depth, and free. Inside also offers newsletters focused on each of the big tech companies, like Amazon or Google. And they now offer inside industry news on fashionable sectors like Cannabis or Beer. – KK

Fake follower audit
None of us have as many followers as we think we do. Up to half may be bots or shills. Every now and then I give myself a reality check by seeing how many fake followers I have on Twitter. I enter my twitter handle into SparkToro. Ouch, 21% are fake. — KK

Find the shortest book on any subject is a search engine for books that estimates reading time to help you find the shortest book on any subject. It’s not flawless, but you can never have too many book search tools. — CD

Quick unsubscribing
I get signed up for a lot of newsletters and PR lists without my consent. I used to take the time to scroll down to the bottom of each email newsletter and click the unsubscribe link (if there was one), but now I just use Gmail’s “Block” to send them forevermore to my spam folder. — MF

Savory meat marinade
My favorite marinade for meat is easy to make and savory. The original recipe is from America’s Test Kitchen and exists behind a paywall so I can’t share it, but the Southwestern Marinade ingredient list here is the exact same. I keep a printed copy in my kitchen. — CD

Card magic DVD
I’ve been interested in card magic for the last five years or so. The best way to learn is not by books (which are confusing), but by videos (which make the sleights and handlings clear). A great video collection for beginner and intermediate card magicians is the 7-DVD set called Complete Card Magic ($25). Get this and start amazing people. – MF

Freeze dried taxidermy/TSA-proof knife/Python Tutorials

Freeze dried taxidermy
Occasionally a small bird strikes one of our windows and dies. Rather than bury it, I freeze dry it. I insert the whole bird into a baggie with a pack of desiccant to keep it dry. The desiccant gel slowly absorbs the moisture in the bird even after it freezes. After a year it is fully dried, and can be kept on a shelf or display indefinitely with all its feathers. This works on birds the size of a sparrow or smaller. — KK

TSA-proof knife
After decades of using a Utili-key as my choice of a small knife to pass through airport security, I lost it in the woods. I replaced it with Victorinox SwissCard. This tool is a mini-Swiss Army knife flattened into a plastic holder the size of credit card but thicker. It has a tiny (1.5 inch) sharp blade, scissors, tweezers, a pen, toothpick, and a pin. You can carry it in your wallet or bag. Goes through security. There is a knock-off version which remarkably adds a magnifier, a light, and four screwdriver heads in the same size card for half the price at $9 — but you’ll need to sharpen the flimsy blade. — KK

Python Tutorials
One of the things I miss about the 1980s was writing programs for fun in BASIC. A couple of years ago I started playing around with Python. It’s easy to learn, and powerful enough to do anything I would want to automate. Christian Thompson’s YouTube channel has wonderful Python tutorials for beginners. Check out the one on how to program a Pong clone. — MF

Advice book on Audible
At the behest of my best friend, I finally downloaded the Audible version of Tiny Beautiful Things, advice on life and love from Cheryl Strayed’s column Dear Sugar. The book is a collection of the most heartbreaking and honest letters seeking help and the advice given. Strayed’s thought-out responses pull from her own life experiences dealing with her mother’s death, drug addiction, divorce, and now as a happily married wife and mother. They are beautiful written and incredibly moving. This book elicits empathy, laughter and at times, lots of tears. There were a few times I was literally sitting in traffic and sobbing listening to her stories. I highly recommend. — CD

Read books in new languages is an online tool that helps you learn languages by reading a book in a foreign language with your native language side-by-side. You can click on any sentence to hear it out loud. I’m not sure how helpful it is to learn an entirely new language, but it’s useful for me to read in Spanish from time to time to remind myself of how sentences are structured differently. Right now, I spend a little time each day working my way through Alice in Wonderland. — CD

Cheap DVD Reader
No one in my family of four has a CD or DVD drive in their computer. That’s a good thing, because we rarely need one. When we do (usually to rip a movie or copy photos or music), I pull out this $15 USB CD/DVD drive and plug it into a laptop. — MF

Theo Gray's Mad Science

Theo Gray's Mad Science ($17) is a rare home-chemistry book where the advice of "don't try this at home" is, for once, appropriate. I usually complain about the scare mongering of home chemistry, but half of the experiments in this how-to book really are extremely dangerous. But the other half are pretty cool. There are no explicit step-by-step instructions given for any of the experiments, just guidelines of what to do. Gray, whose column appears in Popular Science, wants you to do some research and not just be a "script kiddie." Stunning photos of what to expect from each project help. My son and I have done a few of these and they do work. The prime lesson engendered by this book is the sense that the material world is far more accessible to hacking than first appears.

Tom Bihn Daylight Backpack
A couple years ago, before a trip to Europe, I was on the hunt for a new day backpack. The JanSport I had had since high school had holes in it. I wanted something with a clean, minimal design. It’s actually a challenge to find a backpack that doesn’t have a bunch of random zip compartments, pouches, folds, mesh details, and gratuitous textures added for seemingly no reason at all. So I was excited when I found the Tom Bihn Daylight Backpack. It’s got a simple rounded trapezoid shape with a single diagonal zip that provides access to the front pocket. I got it in this really nice French blue color that looks good with most everything I wear. It also shipped fast, and as I recall there was a handwritten note thanking me for my order. It’s made in Seattle, and the quality is solid. I’ve stuffed it until it’s quite full and the seams have held up for the past two years as I’ve used it as a work commuter backpack.

I’ve loved this website for a long time. It’s an online photo gallery born out of the era of peer-to-peer filesharing. It was started in 2004 when a musician named Rich Vogel was using a filesharing program to find music and instead stumbled on a folder of photos. It’s still getting updated periodically, though I’m not sure how often. The collection is thoughtfully curated, like an epic mix tape. Though I can’t always put my finger on why one photo works so well next to another that seems unrelated in every way. When I want to be reminded of how beautiful the imperfection of real life is, I go here. These photos are often the mistakes, the ones the photographer never intended. Some are blurry, poorly framed, or double exposed. People have been captured with weird expressions or unflattering angles, but that’s part of the appeal. They’re stills from the cutting room floor of life. I find humor, horror, love, and glory, in a way that feels rare.

Audio Dharma podcast
Audio Dharma is a regularly updated collection of all the talks and guided meditations given at the Insight Meditation Center in Redwood City, California. A massage therapist recommended it to me after a particularly emotional session a few years ago. I started out mostly listening to the guided meditations, but lately I’ve been more into listening to the talks. They work well for someone who is listening in short bursts, so I’ll put it on for my 15-minute work commutes in the morning and evening. In moments where I’m feeling particularly stressed or sad, these talks can have the effect of helping me change what feels like a less-than-ideal metaphorical posture: when I’m overly focused on the future or the past I have this sense of leaning forward, like my mind is two steps ahead of my body. Audio Dharma helps me realign to something closer to upright — a posture of gentle curiosity. My favorite talks are the ones where the teacher picks a simple human experience, like uncertainty, desire, grief, or generosity, and they explore it in a way that usually leaves me feeling like I have a new perspective on a very common human experience. Most of the podcasts or music I listen to feel like they fill my head with noise that requires additional processing or decompressing afterward, but this feels like the opposite. To use a computer analogy, Audio Dharma defragments my brain.

PocketDisc crocheted frisbee
I like throwing around a frisbee, but I enjoy it even more with my crocheted frisbee. I don’t remember how I came into possession of one of these, but I love it. The main things that make it awesome are that it never hurts if someone throws it at you hard, and it folds up and can fit easily in pockets, purses, and bags. Also: it flies quite well, it can be given as a gift to people of all ages, and it’s safer to use inside the house. When I’m feeling silly, I’ve been known to flip it inside out and wear it as a hat. The only places I wouldn’t recommend it are around dogs, because I imagine they would quickly chew it to shreds, and on beaches. On the beach, the lip of the disc picks up sand when it lands on the ground, and then the next time someone catches it next, the sand gets released into the catcher’s face. I’m sure I could brush up on my crocheting skills and make myself one from scratch, but I feel like these are a good deal, for the money. They also make great gifts.

Can-Gun 1

Using your index finger to press and steer a can of spray paint gets old very quickly. If your paint job lasts more than a few minutes, you really should use a snap-on pistol grip($5). It saves your knuckle, keeps paint off your trigger finger, and gives you an easy way to guide the spray. For years I've used an earlier model of this grip (called simply Can-Gun), but that one was only operated with a single finger trigger. This new version uses your whole palm. It's comfortable, quick-on and off, and the only way to spray. I had a 5-can job on a chain-link fence and the Can-Gun made it kind of fun. Even for small spray paint jobs, I slip one of these on.
