I use several cloud storage services. The easiest way to access them is with CloudMounter, a $49 Mac utility that mounts OneDrive, Google Drive, Amazon S3, Dropbox, and others as local hard drives on my desktop. Setup was painless and it works flawlessly. — MF

I’m totally paranoid about backups. I have my critical stuff backed up five different ways, and I don’t think that is too many. After 35 years, I have not lost anything. Main thing is you need at least one offline backup (I have two), away from your home or office. My main offline backup these days is Crashplan. They have individual, family and group plans, $10 per month. You want to ask yourself, if I lost my entire hard disk, how much would I pay to get it back? — KK

If you suddenly die, your Google data — email, docs, contacts, tasks, wallet, etc. — will be inaccessible to loved ones who might need it. To make it easy for trusted people to access your account, use Google’s Inactive Account Manager. It will grant access to up to 10 trusted friends or family members after Google detects that you haven’t signed-in to your account for a specified number of months. — MF

I’m productive because I outsource my detail work to global freelancers. If I can specify a job, it can be assigned to one of a million expert freelancers working somewhere in the world. Often for cheap, always fast, and securely. I use Upwork (which used to be called Elance and oDesk). It’s a reliable system. I can find programmers, web and graphic designers, artists, photoshop experts, transcribers, marketing mavens, and so on. Their work is a good as anyone you might hire. — KK

80,000 hours is the typical length of the average career. 80,000 Hours is a blog that dispense free career advice based on science, rather than on hunches. As much as possible this non-profit (Cambridge University) gives advice based on the latest academic and scientific research into the nature and economics of work, careers, happiness, and the economy. When I am asked for career advice, I point candidates here to their Career Guide. — KK

The Sokanu Career Test is like a supercharged version of the one I took in high school. A 20-minute test will give you your top matches out of 800+ careers based on your personal interests, personality characteristics, and ideal work environment. You also get info on degree paths, salary, and links to job listings. — CD 

Timelog is a free time tracker you can use in your browser. You don’t even need to sign up for an account. I like that it keeps going even if I accidentally close my window. — CD 

Tomato One is a free focus timer for iOS, based on the Pomodoro technique. I use it when I have trouble focusing. The timer goes off every 25 minutes for a 5 minute break. I make sure the sound is turned down so that the timer ding is discreet, and allow notifications on a locked screen in case I don’t hear it. Most of the time, I end up working through the breaks and get more done. — CD

I use Calendly to manage Kevin’s calendar. Calendly connects to Google calendar, blocks off the times you are busy and creates a unique and permanent url to share so people can self-schedule. The scheduled event is then automatically added to your Google calendar. There is a basic, free plan that does this, and paid plans with more features. — CD

I have great childhood memories of going to estate sales with my mother in rich neighborhoods. Everything but the House is estate sale hunting without the effort. It’s like a more refined eBay. I’ve already spent way too much time bookmarking things and imagining the history of each item. — CD

When I’m in shopping mode I check out BestReviews. Modeled after Wirecutter and Cool Tools, it tests, compares and recommends a huge variety of products, from ATV ramps, to kiddie pools, to pressure washers. It carries no ads, relying on Amazon links for revenue. While its range is vast, the depth of reviews is uneven, but I find their simple summaries of the best stuff worthwhile to check out. — KK

A great hack to know during shopping days is to always check out RetailMeNot before purchasing anything online, outside of Amazon. There is a high chance I’ll find a discount coupon for a retail purchase I am considering. RetailMeNot will give you the coupon code, and the rate of success others have recently had in using it (the codes are crowdsourced). Discounts of 10, 20, or 30% are not uncommon in my experience. I don’t shop without it. — KK

My Subscription Addiction spoilers section is my go-to bookmark when I can’t physically wait to get monthly makeup box from Sephora. But this site is so much more than that. It’s a massive directory of subscription boxes you can search by gender, categories, and countries. As well as reviews, there are promo codes and a free forum for swapping items. — CD

For my tastes, the best holiday gift guide is the annual catalog of cool books, games, toys, and DIY tools put together by The Kid Should See This website. Ordinarily the site hosts the best video clips your kids should see, but during the holidays they compile this long and annotated list of cool stuff that is aimed at active kids, but also works for adults with young minds. — KK

This brief, succinct blog post has great advice on how to find what you want (at least with used furniture) on Craigslist. For instance, don’t forget to search for common misspellings of your target. These tips match my experience in buying used tools on Craigslist. — KK

When I have an idea of what I want, but don’t want to go searching for it at the mall, I use my ShopStyle app (iOS, Android). I can filter my search according to keyword description, color, size, price, brand, department store, etc. The “Tailored Shop” updates daily and personalizes a store based on past searches and favorites — perfect for virtual “window shopping.” — CD

I take full advantage of the Request a Quote option on Yelp. Once you type out your request, Yelp gives you the option to submit the same message to similar businesses nearby. I click the max amount available (up to 10), and find that most people start responding right away! I’ve used this recently to find the cheapest and fastest phone screen repair. — CD

Amazon’s Interesting Finds will give you pages of really cool, surprising stuff. I don’t know how they are curating it, but I particularly like the Fun option. — KK 

Amazon now has a section where they sell originally Kickstarted projects. Bottom up retailing. — KK 

SpyCloud is a scary and useful website. Scary, because it showed me how many times my passwords have been hacked from website databases. Useful, because I quickly changed those passwords to protect myself. A personal account is free. Do this now. — MF
