Agent that browses the web, analyzes information, and creates reports. Grok calls it DeepSearch. Similar to gemini/openai deep research.

Not sure what front page you are looking at. First thing it says on spacy.io is

Industrial-Strength Natural Language Processing in Python

Followed by some decent descriptions and code examples.

Although the theoretical limit is higher I think 25 mbps ± a few is what you can expect in most of the world.

Here are some speed tests by country https://www.opensignal.com/reports/2018/02/state-of-lte

Without reading the paper this seems somewhat similar to my experience with modafinil. When fatigued or sleep deprived it can bring me back baseline but not much more.
Caffeine + l-theanine is the way to go if you feel "inpatient and restless" on coffee alone!

You could start with an even split then adjust the ratio depending on how you feel.

Re:A system to help you remember more of what you read on Sunday July 01, 2018 @09:17AM (#17435483)
It just means distributing your learning trough time, so basically the opposite of cramming.

I guess spaced repetition can be seen as a combination of distributed learning and practice testing.

I got the terminology from here

http://journals.sagepub.com/stoken/rbtfl/Z10jaVH/60XQM/full

Here is a nice summary of the results

I don't own a kindle but it looks like it's possible to download your highlights.

You could then bulk import them, possibly after some minor formatting manually or with a script

https://apps.ankiweb.net/docs/manual.html#importing-text-fil...

You would still have to go trough them and add cloze delitions.

If it's possible to add notes to your highlights you might be able to specify delitions there and then parse them.

I might actually do this myself for fun :)

I've heard some good things about https://www.coursera.org/learn/learning-how-to-learn

To get a quick overview try table 4 p. 45 here

http://journals.sagepub.com/doi/pdf/10.1177/1529100612453266

I try to follow

* Distributed learning/practice

* Practice testning

* Interleaved practice

Re:A system to help you remember more of what you read on Sunday July 01, 2018 @05:10AM (#17434779)
Just skimmed the article but underlining only seemed to be one small part of the method.

Understanding by summarizing into Anki cards and then making sure you remember it trough spaced repetition (both "output") seemed to be the most important part.

Distributed learning, practice testing and Interleaved practice all seem to have some scientific backing.

Re:Ask HN: How do you manage your manager? on Friday June 15, 2018 @07:09AM (#17318893)
This is quite childish advice. Is this your solution all disagreements?

"You will then have the freedom to do whatever you want each and every single day, and won't have to spend all that time and energy constantly convincing someone of things that are often for their own good."

I wish!

Constantly convincing someone of things that are often for their own good is basically the definition of what you do when working for yourself, or should I say when your working for you clients/trying to acquire new clients.

Re:You probably have too much motivation on Tuesday March 27, 2018 @05:07AM (#16686606)
From the MIT challenge? I don't think that was the goal. If I remember correctly the blog, and his paid courses, are mostly about how to learn efficiently. So I'm guessing the purpose was part content marketing, part research and part general interest.

He's done something similar with language learning.

OP is saying that since Lua is cumbersome to write you might as well write in C and get increased performance.

Re:Ask HN: Resources on vitamin D supplements and studies on Wednesday January 10, 2018 @02:16PM (#16117952)
To add some anecdotal evidence... We basically get no sun for half of the year where I live. I find my subjective wellbeing has increased somewhat, especially during the winter months, since I started supplementing with 5000UI D3.

Other potential benefits are harder to measure, but the cost in terms of money and likelihood of adverse effects is so low I feel I might as well continue.

To add another data point, gwern has done some more rigorous self experiments https://www.gwern.net/zeo/Vitamin-D

Re:Ask HN: Resources on vitamin D supplements and studies on Wednesday January 10, 2018 @12:11PM (#16116693)
Examine.com is a good starting point https://examine.com/supplements/vitamin-d/

If you scroll down to human effect matrix you can find links to studies based on results found.

The summary at the bottom is also pretty good.

Doubt it was meant as an attack more a statement of fact. If I remember correctly all the songs used to benchmark the compression were of "western-european" origin. Same thing for the people judging the result.
