For me Duolingo is woefully ineffective. A far better method is Pimsleur plus Anki. Ankify the Pimsleur audio, make your own Anki cards with most of your vocabulary in cloze phrases. Ankify the audio on as many of those cloze phrases as you

I wonder if this scam also applies to executive MBA programs? For example, the Kellogg-HKSTU program cost US$220,000 for about 18 long weekends of on-site classroom time. This is exorbitant, but the Financial Times has ranked the program as

"all other things being equal, the best plan is to let as few things into your identity as possible" If one is opposed to, for example, the genocide of a people of some particular identity, then that strongly held position may its

Most languages also have examples of single words that convey concepts requiring many words to express in English. Always fun to discover these gems. Here's one that I learned yesterday in Visayan: "Manginhas ta". This means

I often travel without a guidebook. To discover a temple without a guidebook, and without having seen single source of information on the location around it, that is real discovery. Everything is unexpected, including finding that temple. I

I’ve been on a new M1 since the day after release. Love it. FAR faster than my previous Mac. But there is some work left to do. It crashes every day, usually more than once. Frustrating but still very happy to have it. Just bought a second

I had terrible sleeping problems: snoring, waking up choking with a dry mouth, very restless, etc. I saw these[1] nasal dilators for $9 on Amazaon and bought them on a whim. It took a couple of weeks to build a habit of sleeping with my m

To be effective you need to use Anki every day. I set my goal for learning and reviewing ambient knowledge at 30 minutes per day. All ambient cards are organized under one “Daily” deck. If studying that deck exceeds 30 minutes, then I reduc

With Anki retaining what you’ve learned becomes a choice. If you put it in Anki, you _will_ retain it. The challenge then becomes, What to put in Anki? I’ve memorized loads of history, often down to the birth years of notable historical fig

I've been without a SIM for over a year. Here are a few more tips: - Google Voice gives you a free number that works anywhere and can be used for texting and 2FA. (There are some exceptions.) - Calling with Google Hangouts is free to s

Other than aesthetics (and perhaps as a hobby) are there circumstances in which cable lacing would be preferable to cable ties?

What a great critique. I'd like to see a similar treatment of Jason Hickel's "The Divide", which feels both terribly important and very biased and sloppy.

My insurance covers glasses in whatever country I buy them, so I never buy them in America. Get the same glasses cheaper and zero deductible or nonsense on the insurance. Just submit a receipt. Done. It's not just glasses. America&#x27

I sail on merchant ships and Lynx is my primary browser on extremely slow and laggy satellite connections at sea. You really need to curate what sites you will use with it because most modern sites degrade to unusable. But when you find one

The depth and breadth of anti-Tesla sentiment in HN threads is curious. It's rarely from owners. By all satisfaction surveys, owners love their Teslas.

Is there something special about deadlifting that achieves this effect over, say, squats? I'm a skinny distance runner but deadlifting is my favorite strength exercise and it does seems to increase libido. I just attributed it to feeli

Wasn't there once a company with the motto "Don't be evil."? If that motto is abandoned, Apple should claim it since they genuinely try do their best to live by it.

The payment system at KFC kiosks and some other places just confirm you with your face. You first have to enter a phone number or other identifying information. Do the vending machines eliminate that first step?

My son (11) is inclined to play Fortnite over essentially all other activities that occur indoors. Outdoors is still a world filled with unstructured fun, but indoors if he's left to his own inclinations then he's playing Fortnit

The Chinese feverishly discover and exploit every scammable niche imaginable, both illegal and legit. This appears to be key to their success. This scam will tank, but the mentality and culture that produces it drives the entire country for

My approach: be in country, do the Pimsleur audio course, obsessively bang out vocab flash cards in the native script, study grammar every morning for 2-3 hours, and (the secret sauce) live with a s.o. who speaks the target language exclusi

In the Philippines the notary is the scam. Only lawyers can be notaries. The lawyers association (the Bar) for each jurisdiction sets the fee. Any lawyer caught charging lower than the standard fee is subject to sanctions. And what&#x2
