Someone sent a link to a simple programming online game. Player had to provide isntruction for an character walking araound a square level, gathering stars. Never could find it again after a month...

Doesn't sound like this is what you're looking for, but LightBot ( http://lightbot.com/ ) is a wonderful game with similar sounding game play.

Thanks :)

When I was looking for the forgotten game, I crawled through the internet and found almost any other available title (LightBot also). I'm teaching computer science and try to collect as many tools (e.g. games) to people with no programming experience.

There was one motivational type article about how you should “go first” or “be first” when approaching problems in life. Like when making friends or just socially in general. I was looking for it again recently but couldn’t find it.

I don't know about the link, but if you are interested in the subject I think that you would enjoy this lecture:

MIT Math for CS, Matching Problems: https://youtu.be/5RSMLgy06Ew

tldw: it can be mathematically proven that the best strategy is to take the initiative when looking for a partner/job/vacancy, starting with your prefered choice and working down from there, and let others shoot you down if need be

I was just doing this yesterday. Trying to find an article describing simple devices that use no external power to send a basic on/off signal (TX–only) over wireless (802.11 I think?). Anyways, it was said to be used for simple applications that send a wireless signal to a receiver when the laundry detergent gets too low. Sort of like Amazon's push button thingies.

The term you want to Google is "backscatter" I think. I reckon this might have been what you were looking for: https://www.washington.edu/news/2017/12/05/in-first-3-d-prin...

I've been trying to find an email server which was mentioned in a comment a few months ago. I read through the setup instructions - the only point I remember is once it's setup one can add as many domains to it as one wants - if I remember correctly. There were several that popped up this past year, https://mailinabox.email this being one of them but I don't think it was the one I'm talking about. The setup instructi…

Email server as in "email server bundle", not SMTP server? If yes, there's Mailcow or iRedMail (among others).

Thanks. It wasn't either one of those. Now that I remember the one I'm talking about, it's system requirements were low. What comes to mind it could run comfortably on a 512mb system.

Earlier quoted context omitted.

I wish I could remember the book, but I originally got it because it's title was something like "Understanding and improving learning", something like that. It ended up being more about the first 10 years of life's learning rather than just learning in general. Still read it because it was interesting. Anyways, to the point. The first few years of someone's life is proven to be crazy important. It's well confirmed wh…

Examples of neglected children (Jungle Book style) are problematic. Learning won't work if their psyche is broken. Better example would be: loving parents who never teach their children anything useful - if something like that ever happened.

Absolutely agree. But the best progress made on how the brain works was to learn from people who received major brain damage/trauma. It's just slightly frowned upon to inflict brain damage to a healthy person for science. [Insert nazi or hydra joke here]. Jungle Book kids are the best study subjects without really crossing bad ethical lines. It's going to be difficult to convince well adjusted, loving humans to never speak to their offspring and teach them absolutely nothing. I'm sure there are some ethical issues there. Don't know exactly. But I know there has to be some ethical and legal problems there lol.

Just thought of this: Couldn't we argue that if it happened early enough and said "animal caretakers", I think one Ukrainian girl was literally raised by wolves, came in early enough, would the kid have psyche issues? Their frame of reference is so limited to knowing what's "normal" and what's not, that they could possibly not develop any actual psychological issues. Actually, them being taken out of that "Jungle Book" environment and integrated into human society would cause issues. Their "Jungle Book normal" was now disturbed greatly. If timeline is true, but they still have psyche issues, could possibly mean that the human brain is wired to a form of "normal" that can't deviate by some certain amount. Just spit-balling ideas.

A service that converts PDF research papers into a clean readable webpage. Their example paper was a research paper with two columns and diagrams to show their service actually works well. I searched a couple of times but couldn't find them again...

Wow, great timing. Around a week ago I spent an hour digging through my bookmarks for something I'd found via HN, and I must not have bookmarked.

I can't recall what the original post linked to, but in the comments someone discussed their preferred method of organizing their digital notes/journal. They linked to a forum post where someone described the system.

It involved using a single folder for all notes, with different categories, that were indicated in the file name. In fact the file name contained everything important. It also discussed never altering a file, but creating an index to refer to other related entries.

I think the person who wrote the forum post was a journalist of some sort? And they might have made reference to a Japanese system that was similar, but physical, which used lines on the top of index cards to indicate categories, and keeping the number of categories low (always 4?) was important.

I'd love to find that forum post again.
