ramidarigaz··on Who's your SSH buddy?
I dunno about jgc, but I just send an email to myphonenumber@txt.att.net

Works like a charm!

ramidarigaz··on Who's your SSH buddy?
I have a similar system, but instead of a plain passcode, I have a (simple, and probably not very secure) hashing method that I can do in my head.

My message looks like this: <machine> <hashed passcode> <number>

The passcode is "hashed" with the number. When the server receives the message, it adds the number to a deny-list. That way, the number is only good for one use.

Also, the number has to conform to a certain pattern. I might change that to a pre-generated list of valid numbers, but for the moment, I can work out a valid number with pen and paper.

Not perfect, but I think it's good enough.

ramidarigaz··on How I Dealt with Student Plagiarism
I think that's pretty much the stance my university takes. We are graded on two things for each assignment. 40% of the grade is how well the program works. 60% is how well we can explain the code. That solves the plagiarism problem very well. I think they almost don't care if I copy the code, because if I can explain it, I have achieved what they wanted me to achieve.
ramidarigaz··on Aaronsw indicted for hacking MIT network to download millions of JSTOR docs
Why would he do this? What is the purpose of having all those documents?
ramidarigaz··on Ask HN: What's your most-used function that you wrote yourself?
A little bit of python that makes it easier to do shell-style scripting.

    def call(cmd):
	args = shlex.split(str(cmd))
	p = Popen(args, stdout=PIPE, stderr=PIPE)
	text = p.stdout.read()
	if not text:
		text = p.stderr.read()
	return text

ramidarigaz··on You should probably quit your job
Why would I quit my job? I like my job! Dammit, stop projecting your own dislikes on to me!

I get to work with really bright people on really cool projects. My work environment is somewhat laid back. I get plenty of time off. Nobody bothers me for not showing up right at 9am. Plus, I have fun here!

ramidarigaz··on A lesson on the importance of encouraging your children with their projects
You can get cheap (essentially free) and perfectly good wood from recycling centers and such places. You don't need a tree to make a fort. I had a tree fort, but I honestly think the most important part is the fort. Even if it's only four feet tall and sitting on the ground, it will still be boat-loads of fun.
ramidarigaz··on Google: Changes Coming To G+ This Week
> "and I do not envy the G+ team"

I certainly do. Seems like an amazing opportunity to do really cool stuff!

ramidarigaz··on Live coverage of the last Shuttle launch (STS-135, Atlantis)
Ah! In that case I do agree with you.
ramidarigaz··on Live coverage of the last Shuttle launch (STS-135, Atlantis)
Not exactly correct. Spacex hopes to do the first resupply mission to the station before the end of the year.

ramidarigaz··on Learn C The Hard Way
Actually learning about the stack was one of my big 'aha!' moments. I sorta' knew it existed, but I didn't really comprehend it.
ramidarigaz··on Learn C The Hard Way
Many of the friends I made in my CS classes were terrible with pointers. I never really understood why they didn't grasp pointers, but it was a major stumbling block for them in C/C++
ramidarigaz··on A cron pitfall that will probably snare you at least once in your career
What do you use instead?
ramidarigaz··on Legend Of Zelda - Link's Awakening, now playable in HTML5
Oh! I didn't mean to blame you! I'm well aware of Chrome's various issues, but this one was new to me.

I didn't mean to detract from an awesome project!

ramidarigaz··on Legend Of Zelda - Link's Awakening, now playable in HTML5
Strange thing just happened when I fired this up. I was playing some other music, and it suddenly sounded like I was blowing out my speakers. I wasn't playing the music very loud, but the bass became extremely scratchy. As soon as I closed the tab, it cleared up. (Win 7 Chrome 12.0.742.100)
ramidarigaz··on Why we are unlikely to ever leave the solar system.
Hmmm... I don't think your analogy is correct. There is a very solid reason that all the air in the room will never only be in one half of that room. It's a matter of pressure, not probability. I don't think the 'rogue' planets are subject to such things, and on a sufficiently long time scale, it could very well be possible for one to travel through our system.
ramidarigaz··on Netflix To Come To Linux Via HTML5
Excellent! I've been holding off on renewing my Netflix subscription for just this reason. Maybe it's time to reactivate?
ramidarigaz··on How to handle 1000s of concurrent users on a 360MB VPS
That's what I use. I thought about the method in the article, but it seemed too complicated, and nginx + fcgi is plenty fast for me.

Are there any performance benefits to having Apache as well?

ramidarigaz··on Square’s Disruptive New iPad Payments Service Will Replace Cash Registers
I think it's for the same reason the just using the number increases the rate. It allows someone to snap a picture of your card without ever having to touch it. The magnetic strip adds a bit of complexity to getting the data off the card.
ramidarigaz··on Boot a linux kernel right inside your browser.
Woohoo! Kernel panic! Haven't seen one of those in... well... forever. (Newbie here)

Edit: This is damn cool.

ramidarigaz··on Remind HN: STS-134, Space Shuttle Endevour's last launch is at 8:56AM ET
That must sound incredible in person. Even the youtube version is amazing.
ramidarigaz··on Netflix for select Android devices now available
If they can make it available for Android, can we have it for Linux in general? That's the one thing holding me back from renewing my subscription.
ramidarigaz··on What Every C Programmer Should Know About Undefined Behavior #1/3
If the compiler can optimize that away, what's the proper method for checking p?
ramidarigaz··on Google Chrome Hacked?
I doubt FF4 is more secure than Chrome.
ramidarigaz··on Linode launches native IPv6 support
I'm really glad to see IPv6. I dearly love Linode. But only one address?
ramidarigaz··on After botched child porn raid, judge sees the light on IP addresses
My understanding is that proprietary router firmware may have unknown vulnerabilities that someone could use to discover the MAC addresses of computers making specific requests. That would allow, for instance, law enforcement to tie internet usage to specific computers.

DD-WRT and other open source firmware should be a little more secure in this regard. The open source firmware out there is definitely more reliable over long periods of time than the stock firmware that comes on most routers, so I assume it's also more secure.

ramidarigaz··on What is the truth behind "9 out of 10 startups fail"?
Or get a job at a lab that sends satellite instruments to space. Work on really cool, mission critical software. Work with really bright scientists and programmers alike in a very relaxed and fun environment. Just sayin'.
ramidarigaz··on FBI seized PokerStars.com, FullTiltPoker.com, UB.com,... domain names
/sarcasm

Looks like you might need it.

ramidarigaz··on Virgin Galactic hiring fulltime astronauts
ITAR basically sets the restrictions for who can use things that are on the Munitions List. That includes rockets, satellites, sensitive data etc. That's in addition to the usual missiles and bombs and whatnot.
