I'm not GP, but the first statement doesn't make too much sense. As a Venezuelan, I think he means the second one.

Which is pretty accurate.
ipince··on Duke U challenges students to improve Duke life using tech. $5000 in rewards.
The iCampusPrize at MIT does exactly that. It has $15,000 in prizes and it has been running since 2008.

It has two stages: (1) for prototype submissions and small prizes of ~$1,000, (2) final fully-working submissions and big prize of up to $10,000.

We entered the competition in 2011 with a book exchange site and won ~3,000. The site's still running.

Past winners: http://icampusprize.mit.edu/past-winners/

ipince··on A Story to Explain Genetic Algorithms
I would suggest making the fitness function more complex. I think its a bit confusing to see the optimal result be equal to the fitness function's parameters, and it makes it easier to miss the point.
ipince··on A Story to Explain Genetic Algorithms
I'm a python noob. Why does a kitten die? You're creating a new list of the same size of the source list (once) and iterating over it. How can you achieve the same w/out creating a new list?
ipince··on LLC vs. S-Corp vs. C-Corp
Can you clarify this:

"But then if you end up not spending that money because you made a boatload of cash the next year and want to take it out:"

Why would you have to pay taxes again? Sure, you can pay taxes on the growth, but you wouldve paid taxes on the growth even if you had taken it out.

Clearly I'm missing something, so please clarify :-)

ipince··on Mystery Cable Activated in Cuba
Hi Rafael! Assuming you're Venezuelan, you're the only one (beside myself) that I've seen in hacker news. I'd be interested in chatting about what you're doing and your view of Venezuela's situation. Please email me (find email in profile). Cheers!
ipince··on The Simple Math Behind Early Retirement
And myself too, please. It would find it extremely helpful. (Email in profile).
ipince··on Why I learned to "make things"
He says he's an analyst. Presumably he was looking at data.
ipince··on Mass shooting at Sandy Hook Elementary School in Newtown, Connecticut
How do you have them have social interactions with other children and adults? (Just curious since I believe it's extremely important).
ipince··on Mass shooting at Sandy Hook Elementary School in Newtown, Connecticut
Unless you get stabbed on the neck or get your stomach punctured, I think the chances of surviving a stabbing are high.

which was the first one?
ipince··on Survey of MIT Students on their Stress
For those who don't know the numbers, 18, 8, 5, and 6 correspond to the sciences, math, physics, chemistry, and EECS, respectively.
ipince··on WhatsApp Hack
Hopefully you don't :-) still, it would be pretty unwise for people to input their credentials there.

Instead, just put the code up on github and link to it. The curious but cautious people would be able to verify the hack then

ipince··on WhatsApp Hack
Can you clarify what each input means? When the help text for the "name" field of a form says "the name you'd like to use".. well, it's not very helpful. Thanks :-)
ipince··on The YC VC Program
I didn't know what a visa waiver was. For others:

Sadly, my country is not in the list, so I have to pay up.

ipince··on McAfee’s Third World Travel Guide
I grew up in Venezuela. Most of what he says is true, except I'm not a drug-dealer, so I haven't been in many at-risk situations. I've either provided some "documentation" in cases in which my license or medical certification was expired, or I've taken the "confrontational" approach: provided valid real documentation and not letting myself be intimidated/harassed by them. I've done this in cities though, where the risk is much lower.

I hate being part of the corrupt system. I rather have them give me a ticket. Problem is, they don't want to give you a ticket. If they find something that they can hold you up for, they will try to get money out of you instead of arrest you. In the end, for practical reasons, it's better to just part with a few dollars.

In some cases, I've had to watch them as they "search" my car. You keep an eye on them as they do it so they don't plant drugs on you (they sometimes do).

Name-dropping is a common tactic too, but I've never used it myself. My friends have.

ipince··on A breakdown of how I was talked out of $100
Funny. A few months ago I was subject to the exact same pitch. Everything exactly the same. As I read I thought "wow, these cosmetics companies got this down to a science." Turns out it was the same company, so who knows.

The only difference was that my salesman was in fact a woman, a very good looking and flirty woman. At the end of the day I didn't buy anything and I could feel her hatred towards me. Left a bitter taste in my mouth.

ipince··on The “Few Months In” Checkup for Startups
"Be aware that pictures and other things you write down (including emails) can be used against you for legal/tax purposes. If you’re living out of your office or visa-versa, you didn’t tell me, and you don’t have any pictures. It can be dealt with, but you’d rather not."

Uhh.. What? Clarify?

In general, please fix grammar. Lots of issues that actually make the list harder to understand.

Thanks for putting it together. It's pretty useful!

ipince··on Show HN: I built a thing
I need this, thank you! How do you get the local phone number? won't I have to pay for it anyway?
ipince··on I Don't Have Time
I don't understand. How come this seemingly personal blog is on github.com? Thanks!
ipince··on Fred Wilson's Email Stats
Those graphs were really confusing.

The email volume line graph. Are those data points per hour? every half hour? How can they have a seemingly continuous line graph for this histogram-style data?

The "<20 words" graphs.. they don't look cumulative but the labels make them seem like they are. The correct labels should be, for example, "20 <= w < 30".

ipince··on The Most Memorable Quotes (I Could Capture) From Startup School 2012
jasonshen, you misspelled at least 4 of the names of the people you covered. I wouldn't have said anything if it was just one or two (everyone makes mistakes), but 4 (at least) is kind of excessive.

Edit: in fear of downvotes for calling jason out on such a detail: I think getting people's names right is important; it shows attention to detail and respect for the people you're naming. (It's also a pet peeve of mine, but that's irrelevant). So my comment is meant to be constructive criticism. BTW, the names that are misspelled (that I know of) are:

Kalanik -> Kalanick; Collision -> Collison; Andressen -> Andreessen; Preston Warner -> Preston-Werner

(I didn't write them before because I was on my phone and it was time-consuming to do)

ipince··on What the Heck Is CSS Specificity?
"Elements can never beat a class selector, even if you pile them on"

Uhh.. what about classes? Can you pile classes on to beat ids?

Can you pile ids to beat inline? (Well that kinda doesn't make sense).

ipince··on Coursera's Functional Programming - Cheating Discovered
I (unknowingly) posted my code for the class on Github. As you point out, I did it with the "yay public code" mindset, not thinking about cheating at all. I'm taking it down right now and apologizing to the Coursera staff.
ipince··on Automatically Check In To (get an awesome seat on) Your Next Southwest Flight
Why only Southwest? Do other airlines not allow this?

Also, are you using some API or a more "primitive" method?

ipince··on “I am calling you from Windows”: A tech support scammer
ok. I think it's more worthwhile to spend that time trying to bring the company down, not wasting 1 guy's time, out of hundreds or perhaps thousands.
ipince··on “I am calling you from Windows”: A tech support scammer
No, bu why actively screw with the file and rank employee? Assuming he just gets a salary, cool, waste all his time (which costs the scamming company). But if he works on commission then why bother?

I would put my efforts in bringing down the company itself. (In fact I am actively fighting a company that tried to scam me. But their low-level employees? I prefer to give them the benefit of the doubt).

ipince··on Conflagration: Zynga’s OMGPOP acquisition torched nearly $500,000 a day
Pardon my ignorance, but what does this mean? That Zynga will pay OMGPOP less than what we had heard? How can they do that?

(Sorry I'm not from around here and don't understand the "write down" language. I presume it's different than "underwrite").

Edit: from trotsky's comment I'm assuming it means they now value it for $x less than what they valued it before (what they paid for).

So how does this influence/affect the guys that came with the acquisition?

ipince··on “I am calling you from Windows”: A tech support scammer
While it's fun to do this, sometimes I think of the flipside. This scammer is probably trying to make a living and support his family. The company's owner though, is probably not in the need to do these unethical things. He/she should be screwed over.

I'm not advocating for his actions, just offering another point of view. Is it always correct to assume that the guy who xut you off in traffic is just an asshole, or does he really really need to be somewhere right now (eg. a hospital)?
