ajray | 14 years ago | 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.

This is why google takeout is part of my backup strategy. http://www.google.com/takeout

ajray | 14 years ago | 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 | 14 years ago | 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 | 14 years ago | on: Ask HN: What do you do on the weekends?

I build flying robots [http://diydrones.com/]

ajray | 14 years ago | 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 | 14 years ago | 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 | 14 years ago | on: Karl Berry: Texlive 2011 pretest available - hopefully final rc

Being excited for this has raised me to a new level of geekdom.

ajray | 14 years ago | 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.

my first thought is that I really want an android app for this.

ajray | 14 years ago | on: Try Arc

This should be especially popular here as Hacker News was built in Arc :D

ajray | 15 years ago | on: Our Open Science project is looking for a dev

Why does the subscription tell me I've subscribed to SynBioWorld?

ajray | 15 years ago | on: Ask HN: What face recognition framework should I use?

OpenCV is my favorite Computer Vision (CV) library. http://opencv.willowgarage.com/wiki/

Face detection is a special case of Haar-wavelets, which are essiantially recognitions that can be 'trained' by reinforcing with positive and negative images.

OpenCV comes with some really well pre-trained Haar-wavelets for recognizing faces. http://opencv.willowgarage.com/wiki/FaceDetection

I am a research scientist but not a web developer. Is there anyway/anywhere I can sign my email up to be notified when an Alpha/Beta is available? I'd love to contribute if possible!

ajray | 15 years ago | on: How to strip JPEG metadata in Ubuntu

Commented on the post as well.

EXIF isn't the only metadata in jpeg files. IPTC and other forms exist, so if you want to really make them clean make sure you get everything.

exiv2[0] can be used to do that. I have a script I use to remove all metadata from sensitive images I collect for research (UAV aerial photography) before posting).

ajray | 15 years ago | on: First-ever images of the entire Sun

I actually debated posting this earlier today and decided against it (wasn't sure it was HN-appropriate). I'm a newbie so I'm learning every day.

ajray | 15 years ago | on: Who else is hacking a project instead of watching the Super Bowl?

Doing circuit board layout and ordering samples online for my next embedded electronics project.

ajray | 15 years ago | on: Solitude & Leadership

I just got started on HN recently. This weekend alone I've probably read >70 HN stories. I'm taking time I should've been studying and working to do them. This story was exactly what I needed to break that vicious cycle.

Thank you.

ajray | 15 years ago | on: GNU/Hurd in 2010

The original post of v0.01 Linux (by Linus Torvalds):

"I'm doing a (free) operating system (just a hobby, won't be big and professional like gnu) for 386(486) AT clones."

He's referencing the project that became GNU/Hurd.

What I'm saying is that they've been working on it since the inception of Linux, and it's still not done yet.

(Found that post while working on a google summer of code project for Minix. I really really really want Hurd to come out because I'm pro-microkernels)

ajray | 15 years ago | on: Arduino: The Documentary has been released.

I'm a student in Electrical and Computer Engineering, so Microcontrollers are bread and butter to me, but what really has amazed me about this platform is the number of non-EE's I see and help use it.

For engineers, the idea of using a wii nunchuck to control color LED's is trivial. For an artist or a design it can be world-changing. And our local arduino group does just that :-)
