No. The sintering happens layer by layer. So you can print hollow parts.

The automatic lead advance works like this: When the lead sleeve is retracted by any amount, it springs back to it's full length and along with that advances the lead by that amount. The way this happens in practice is as you write, the lead wears down till the sleeve rubs against the paper. Usually we write with the pencil at an angle with the paper. This angle causes the lead sleeve to retract when it rubs on the paper and then when you lift the pencil for the next stroke, the lead sleeve will spring back into position advancing the lead with it.
If you're interested in more details and how the mechanism actually works, here is a good link: https://stationery.wiki/Auto-Advance_mechanism

Opossum | 7 years ago | on: Yelp craters 30% as advertisers abandon the site
I have a question: Would it be possible to do something like Fakespot for Yelp reviews or just restaurant reviews in general?
I can appreciate that the problem is harder than say spotting fake Amazon reviews, but it seems plausible.
Given that there is really no good verification for restaurant reviews, there must be a ton of fake reviews out there. In theory, it would not be too hard to periodically crawl reviews and figure out when/if they got deleted and use that dataset to find patterns.

Another maker of excellent wooden models is Wooden City (https://wooden.city/).
We built their Ferris Wheel model. It was very well designed, a lot of fun to build and the end result was much better than we anticipated!
The 4x4 looks amazing - will be building that next.

I'm surprised no one has mentioned Tesla in this context. Not only do they make it almost impossible to get a Tesla car repaired anywhere but their service centers, but they also collect a ton of data [1].

Anybody have good recommendations on courses or a curated study list for someone new to Design in general? Looking to learn fundamentals before diving into more detail on any specific field.
Opossum | 9 years ago | on: Alphabet's Project Loon says it will run the program with fewer balloons
Totally agree. This seems like a clickbait title to cash in on the "yet-another-cancelled-Alphabet-moonshot".
It's unfortunate that this particular article about this story is on the front page of HN when there are several others[1] that contradict this headline and actually even provide more information.

They actually introduced a new line of laptops called the MacBook (so the title is technically incorrect). The existing MacBook Airs and 13" MacBook Pro got minor refreshes. Interestingly no refreshes on the 15" Pros.

Fantastic show! I especially loved the Puzzlers [1]. They had some really interesting ones over the years.
Tom will be sorely missed! :(
