Firefox 3000 should arrive no later than Summer 2016.

Why is in the best interest of our country to build fences? No, building a free-transit area akin to what Europe and Mercosur have would be way better. But I know that won't happen, because of the strong assymetry between our countries.

But anyway: Yes, university education is free and has a very high level. But we do lack in many aspects. My university is huge (350,000 students; the main universitary campus is about 6Km, which would be about 3 square miles; around 35,000 full-time academic staff). However, it only manages to accept about one tenth of the people that try to enter (and some courses, mainly in the first semesters, have up to 70 students — Far from ideal. I teach, however, in 5th-6th semester courses, and my groups have been 15-35, much better).

But how many people reach university? Or how many people reach even high school? If your work is needed at home at age 12 because there's no other way the family has enough money, most probably you won't ever consider entering a university.

And... Guess who are the people that leave the country for the USA without proper migration documents? Right. It's not the lucky ones who get through profesionalization, but those that don't have the opportunity.

So, yes, there is no contradiction between us having very good universities and very low income, particularly in some areas. Of course, there's a lot to criticize our government's priorities about. But it is also not by a long shot a simple problem to solve.

I would be more interested in making it harder for educated people to migrate (legally) to the USA. If one of my students graduates and leaves to work in the USA, he will probably earn 5-10 times as much as here (to begin with), but it will also be a waste of public resources, because his talent and intelligence will not benefit our society. Funding universities is a long-term investment from a government, and the only way to get a ROI is to have the students stay here for their professional life.

...I find this whole thread really amazing to read, and almost impossible to understand.

Most countries I know have large, well-reputed public university systems. I happen to work on the largest university of Mexico (and Latin America), UNAM. Tuition? Virtually zero (there is a 1940s law where it stipulates a tuition for this university... It currently sits at MX$0.30, or ~US$0.02 per semester). Most public schools in Mexico have 100% free programs. Not only that, the same situation holds for most of Latin America. And that's for college level ("Licenciatura") — Want to study a Masters or Doctorate degree? In all of the "excellence"-rated programs, you are automatically entitled to receive funding from the government so you don't have to find a way to pay for your life while you work to become a more productive member of society. And yes, we do have private universities, often as expensive as USA-based ones are. But the fields where they excel are usually very different.

I know this same model exists in most Latin American countries. European states have a somewhat different program, but still, public (government-funded and tuition-free) universities are all but the norm. I just cannot understand how the USA continues to function (some would even say, thrive) under such schemes.

I did read your previous comment, and did reply to it.

Again: I offer you $100 for your vote, if you prove me you voted for my candidate. You go in and vote. You generate this secret code, known only to you. Then, you come to my evil lair, connect via my computer to Teh Interwebz, and type in your secret code. The system verifies you voted for my Master, and I give you your well-earned money.

That should be impossible. But any system where you can prove *to yourself* you voted a certain way opens the door to vote selling or coercion.

Of course, it's obvious today that a test for behavior on inconsistent requests should have been done in OpenSSL. As well as a test for each failure cause should have been done by Apple. And next week, when an off-by-one bug bites us on an integer overflow in libfoobar, people will say testing for that condition should have been trivial.

So, yes, some conditions can be found with fuzzers. Of course, fuzzers work in an erratic way, and not all bugs can be triggered by them. But maybe fuzzing our code (more importantly, our security-sensitive code) will yield better results than preparing tests for those components in the system we are aware of.

Then again, properly fuzzing takes quite a bit of time. It is way less fun to watch a fuzzer than to see tests making green check marks...

The problem with voter-verifiable systems is that they are very prone to vote coercion or buying. If you can prove your "right way" vote was correctly counted, you can get the cheque. Or avoid the punishment for exercising your free will.

Say this system is approved. Say you want to buy my vote. You demand proof that I voted the way you wanted me to — If the e-voting platform allows me to confirm my vote was properly counted. So, all you have to do is to promise me to hand over the money if I prove you I did what we agreed. (or you can threaten me with physical violence unless I can prove it to you, same reasoning).

A secure voting system should never allow me to prove what was my vote — But that would make me very suspicious, as it could be recording false votes from the beginning, right? Right. The only solution is to have voters deposit papers with their stated vote (and no personal identifying marks!) in a booth, and allow for recounts if needed.

Your scheme is very similar to what we use in Debian for voting for the project leader (unlike the fully-open tally sheets for voting on issues, not people). However, this scheme is good only where people trust each other, for ocassions where you know there will be no vote buying/coercion. Not for a national elected government.

If you can prove your vote was correctly recorded, then you might be more easily persuaded to sell it — be it that you receive a pay for it, or you receive the service of not getting your bones broken.

A vote once cast is just a piece of paper among many. Nothing should tie it to a voter's identity. A voter should be unable to prove he voted a particular way.

It might still happen, but many among us will still fight for the population to understand the unavoidable security risks in doing so. We have the duty to do so.

I once asked this to an Estonian government person at a e-voting presentation in my country. Her answer: "We let you vote many times. Only the last one counts."

That would allow you to vote at the workplace, then go home and vote again.

Of course, you can gather people at the election day, two hours before booths close, and have everybody vote for $foo. Then, throw a party and lock them in (or something like that), and secure the vote is "right".

In a small country with 1.3 million inhabitants, a couple tens of thousands of votes can be decisive.

Or: How small the margin for a polemic vote? In Mexico, we have had presidential candidates winning with a (much disputed) 0.55% difference to the second place. How many votes do you need to rig such an election?

I cannot tell you how much I thank questions. All of them, even the dumbest.

I do try to be very clear and dynamic, but some topics... are just hard to grasp, or I have not found the proper way to teach them... But in some subjects, most students won't even realize they are not getting what I teach. There are a few students who are burnt with questions, and cannot stand on a point they don't understand. Some students insist on their questions even if they are sometimes just too easy.

I thank them. And I try to explain, over and over, from different angles. That's what brings back the attention of the rest of the class, and the different angles are in the end good for all of them.

Not precisely.

Yes, they are free. But the scientific world revolves around the notion of the different metrics to your work. And it's not only prestige: Often, your income level will be determined mainly by the impact factor of the magazines you publish in.

But... Guess who dictates the values for said impact factors in the international indexes?

Of course! The publishers of closed sciencie magazines.

I teach "Operating Systems". And yes, I don't expect (I'd love, though!) many from them to have to implement a Second-Chance (Clock) memory page replacement algorithm. But I do expect them to understand how duing professional their lives the programs they write will be treated by the operating system, and how to avoid bad performance resulting from inefficient patterns.
