ajray··on Why You Should Build Something
Protip: If you're using Chrome, just add 'cache:' to the beginning of the url to get the google cache of the page.
ajray··on The lasagne theory of game design
The analogy reminds me of Shrek. Ogres have layers, so they're like onions, which have layers, but not like cakes that have layers? I think the article would have been fine without that analogy, and just dove into the relationship and differences between the 'layers'.
ajray··on Judge Alsup asks Oracle/Google to brief API issue in light of new EU ruling
While that's a nice thought, I don't think that ruling in favor of Oracle will magically make Android poof into a new language/api/framework. It'd take lots of effort, and in the meantime fall way behind Apple. I'm not even sure the cost of trying to keep up with the iPhone would be justified in that case.
ajray··on XOR Linked List
Yeah, there's going to be these trade-offs (complexity/efficiency), but I've seen this end up in fellow student's personal projects after learning it in class.

Aside from that though, I think if you're clever enough to come to this and implement it well, I hope you're clever enough to understand whether or not it's the RightWay(TM).

ajray··on Samsung Galaxy S III hands on: fast, thin, and a little bit cheap feeling
It seems like we're due for a new Google Flagship Tablet device soon, though I haven't seen any news to that effect yet.
ajray··on Samsung Galaxy S III hands on: fast, thin, and a little bit cheap feeling
If you're counting the Samsung, Google, AccuWeather, and ChatOn logo's, sure. Without those we're left with a still diverse set, but I think reasonably varied. If I could make one change it would be to make the clock font match (style-wise) the rest of the non-logo fonts, probably at a much lighter weight (ultralight serif).
ajray··on Samsung Galaxy S III hands on: fast, thin, and a little bit cheap feeling
He doesn't appear to back it well in the article other than as a quality of the plastic. Reviews are subjective, and as the next Google Flagship device, the S3 will be getting lots more reviews soon enough. Personally I like the Verge's Android phone reviews.
ajray··on Samsung Galaxy S III hands on: fast, thin, and a little bit cheap feeling
For me the biggest turn-off is the pentile display. I think for now I'll just keep the HTC One X.
ajray··on Git Subtree merged into mainline git
Additionally useful: Text file explaining the command and usage (from the commit): https://github.com/gitster/git/blob/634392b26275fe5436c0ea13...

Examples are at the bottom.

ajray··on Git Subtree merged into mainline git
I hope to see Android's 'repo' tool improved to (optionally) make use of this.
ajray··on R/C SR-71
RC Aircraft nerd here. This is very cool, but not at all uncommon (while this particular model is, making scale remote-control versions are not). Pulse-jet aircraft are some of the coolest things you can fly, but need a big field (for safety reasons).
ajray··on Epilogger Pivots to New Direction: Unicorn hunting.
Add it to the other lists of april fools jokes?
ajray··on Mind-boggling XKCD April Fools comic
Randall will probably put up a way to permalink it after the fact. It looks like http://xkcd.com/1037/ (which should be this comic number) is 404'd.
ajray··on Show HN: my "My Latex resume" project
That was part of the inspiration for mine, https://github.com/machinaut/XeTeX-Resume/blob/master/modern... (the github repo has all of the source). Dario Taraborelli's other articles are the reason I use XeTeX instead of LaTeX.

It's a good format, and I like having a bit of color in mine (and the QR code is just a bit of nerd-edgy).

ajray··on XeTeX: could it be TeX's saviour?
I just use XeTeX so I can get proper kerning and ligatures. Oddly enough, as a typography nerd LaTeX just doesn't cut it.
ajray··on How a Web Link Can Take Control of Your Phone
Maybe I'm not sure about how tech-savvy most people are, but when I get a text message from an unknown number claiming to be my provider asking me to click a web link to update my phone, I know something's up.
ajray··on Does being wealthy make you unethical? New research suggests it does
Correlation versus causation, guys. We're better than this.
ajray··on 4th State of Water
As someone who did computational modeling of water, this strikes me as kind of odd. The "hello world" of computational molecular dynamics is simulating water in different phases, phase changes, etc. (including the different ices). I'm interested to hear more, but incredulous.
ajray··on Upverter (YC W11): the perfect tool for open-source hardware
:-( I was planning on doing this for YC next summer. Looks like I got beat to the punch.
ajray··on Ask HN: tiny VMs
I've actually heard this question asked a lot in a bunch of different forms, and (to me) it basically comes down to: How do I use virtualization to provide additional security to processes?

The advantage of virtualization is that it provides a very strong statement of security (if a lesser statement of performance). On the other hand Jails/Containers (see LXC) have a strong statement of performance and a lesser statment of security.

For you, I'd recommend checking out Linux Containers, because it does provide more protection than just a process, but is faster and uses less resources than a whole VM.

ajray··on How I Dealt with Student Plagiarism
As someone who hopes to be a future professor, posts like this are extremely valuable to me.

I hope that some of the good that's come from this media storm is we'll have a surge of great ideas on how to design courses and assignments to minify plagiarizing.

ajray··on Google account gets blocked without explanation
This is why google takeout is part of my backup strategy. http://www.google.com/takeout
ajray··on Confessions of a custom-essay writer (2010)
As someone who (sometime in the far future) aspires to be a professor, this is an important thing to hear. As a student I guess I was ignorant about how available services like this are, and as a professor I'll definitely be wary about it (and possibly design assignments around making this sort of thing difficult or less rewarding grade-wise)
ajray··on Bottle: Single-File Python Web Framework
This is exactly what I was looking for. Got up this morning and it was #1 on HN. This is why I <3 HN. Thanks for solving my problems again :-)
ajray··on Ask HN: What do you do on the weekends?
I build flying robots [http://diydrones.com/]
ajray··on Anyone want some Spotify Invitations?
Thanks! I think i grabbed the last one of these though. (If you test a whole batch and they're done, reply with that).
ajray··on Netcat cheat sheet
I'm trying to convince my officemates that "Hacker News" isn't about computer hackers, but this link is the most useful on the homepage to me :-)
ajray··on Karl Berry: Texlive 2011 pretest available - hopefully final rc
Being excited for this has raised me to a new level of geekdom.
ajray··on Ask HN: How long does it take to learn Common Lisp
This is a hard (if not impossible) question to answer. It will vary hugely based on a lot of different factors:

How many languages do you already know?

How long have you been programming?

Have you done any functional programming before?

Are you familiar with lambda calculus?

and the list goes on.

ajray··on Brady Label Maker
my first thought is that I really want an android app for this.
