amatus··on Seeking Big A.I. Advances, a Startup Turns to a Huge Computer Chip
I'd love the see the details of how they remove heat from that monster chip.
amatus··on GNUnet 0.11.5
Here's a few things GNUnet replaces and why it's better:

Bittorrent is replaced by GNUnet "filesharing", it's trackerless, it provides a search function, users can adjust their level of anonymity for publishing, downloading, and searching.

DNS is replaced by "GNS", it covers the "decentralized" and "secure" points in Zooko's triangle, it a pet name system.

VPN is replaced by GNUnet VPN, which is just VPN over GNUnet so it can take advantage of the p2p network.

TCP/UDP/SPDY/QUIC is replaced by "cadet", takes advantage of the p2p network.

There's also a DHT.

And there's lots of other stuff that's in-progress.

If you want more solid evidence of unsafe driving, you could mount an ultrasonic distance sensor to your bike: http://codaxus.com/c3ft/c3ft-v3/
amatus··on New study dramatically narrows the search for advanced life in the universe
Do you mean the Drake equation? The relevant factor would be n_e "the average number of planets that can potentially support life per star that has planets"

I love how they published a picture of the keys[1].

amatus··on Tesla Autopilot
Are we heading toward a future where it's illegal to drive your car on the road if you have modified its software?
amatus··on Ask HN: What are we doing about Facebook, Google, and the closed internet?
The website is one of the things we need help with. If you want something more detailed than the About GNUnet paragraph there's the key concepts[2] and user handbook[1].

amatus··on Ask HN: What are we doing about Facebook, Google, and the closed internet?
I'm working on GNUnet[1]. It needs a lot of help.

I'd like to see that stand up to mom vacuuming right next to the unit.
amatus··on Show HN: An app for your older relatives, helping them find the right cables
You're missing a cable I had to buy recently for my father-in-law: Laptop to monitor: mini display port to DVI (specifically DVI without analog pins or it wouldn't fit into the plug on the monitor).
amatus··on On Two Views of Computation in Computer Science
Could you encode all untyped lambda calculus expressions by just numbering them and writing the number as the string of bits?

Maybe this enumeration is the "external collaborator" in this case, but it's a very simple one.

The article mentions the bacteria works at "a steady 86 degrees Fahrenheit." It may work slower or not at all at Pacific Ocean temperatures.

Sometimes you need a diode and all you have in your parts bin is a bridge rectifier with half the current capacity.

amatus··on IBM is trying to solve computing scaling issues with electronic ‘blood’
They didn't quite solve the cooling problem though ;)
amatus··on YouPronounceIt: Search for a word, get videos of YouTube speakers pronouncing it
It would be nice if you could specify the part of speech also. For example the verb and noun pronunciations of associate and attribute are different.
amatus··on Aluminum and strength
Sorry, I only know some XRF, I don't know metallurgy.
amatus··on Aluminum and strength
Looks like the Liquidmetal alloys are zirconium-based, the XRF showed that it was an aluminium-based alloy. So, no.
amatus··on Aluminum and strength
It's interesting that the new alloy was not recognized by XRF. In the video it looked like they had a large set of standards from which to build an empirical model. I don't know how likely it is that Apple created their own alloy, but I have experience with XRF analysis and I know it's easy to make mistakes preparing a sample. It's possible the tungsten came from the sandpaper used to remove the anodization layer or it might have been part of the anodization layer. Another tricky detail when analyzing materials is how the different elements adhere to the surface. The X-rays only see the atoms at the surface. If sanding the alloy removes more of a softer metal or smears it over the surface covering the other elements you may get inaccurate results.
amatus··on The Weird Abandoned Spaces of Virtual Worlds
I had joined Active Worlds back when it was called AlphaWorlds[1] and before that I enjoyed Worlds Chat[2]. It was an interesting universe to explore. I didn't build much since their library of pre-made objects didn't have enough variety and you saw the same objects everywhere. You could model your own objects but I had trouble finding free software I could use for that. I hadn't logged in to Active/AlphaWorlds for a while and when I came back to see how things had changed they started charging for accounts. I had forgotten my login info and I wasn't willing to pay for a new account, so that was the end of that.

Thanks for mentioning it. I love Eliezer Yudkowsky‘s writings on quantum physics. I look forward to reading this: http://hpmor.com/
amatus··on NP-Complete Problems and Physical Reality (2005)
"If some physicist wants to continue the tradition of naming quantum gravity theories using monosyllabic words for elongated objects that mean something completely different in computer science, then I propose the most revolutionary advance yet: thread theory."
