Comment: As an American, I disagree. (Score 1) 538

There are over 8,000Km of America (how many miles would that be?) South of your border. The name "United States of America" means that, among the existing States in America, some decided to unite and become a nation — but that nation does not necessarily span all of America.

Having so many publishing venues available right now, with (thankfully) every day more of them available under open access licensing schemes, we can get to much more research in our field.

That, however, means that when I start reading on a subject related to my area of study, there are too many documents fighting for my attention. And I will undoubtedly miss many among them, just because of sheer probability.

Of course, the same will happen to my published works: They will no longer be _so_ unique, they will also depend on my luck for you to read them.

If your family has had a mezcal for 4 generations, it just means they don't drink alcohol, or have it really well hidden. Maybe they have had a temazcal (similar to a sauna, but with far more associated rituals to it) ;-)

Universidad Politécnico does not exist, in fact. There is a long-standing rivalry between "la universidad" (Universidad Nacional Autónoma de México) and "el poli" (Instituto Politécnico Nacional). Nowadays, I teach at UNAM and am a student at IPN :-)

Huichol is spoken in the West. Náhuatl is the dominant indigenous language in the center of the country, the different types of Mayan in the East. But there are over 60 distinct indigenous languages throughout the country.

Just like... Mexico City!

I am Mexican, living in Mexico City. My wife is an Argentinian, from a mid-sized province capital. She often finds it laughable how this city lacks any logic. Of course, until it becomes clear that most quirks come from agricultural, old villages that got slurped into the Blob. Then its shape is explainable... Not that it makes much sense, of course.

Holy Hell, I hope you mistyped something!

It is 2015. If you've got a single password (your private key) with root access to that many machines, something is terribly wrong over at Debian.

Others have replied, but I think I should do so as well: Yes, we don't use a PGP key to log in to thousands of machines, but we use it to validate package uploads that enter the archive. If I sign+upload a malicious binary package, it's just a matter of time until it reaches users.

Of course, there are some caveats: First, I must convince users to use my package. This is, my malicious code should not go in a very uninteresting package, it would go to one that I know that has many users. But, second, it should not attract too much attention, as others would likely find my backdoor. Say, if I wanted to reach maximum number of machines, I could update an "Essential" package, such as base-files. But first, the package is not mine (so my friend Santiago, the package maintainer, would jump at the unexpected upload). And it does not get updates often, so others would probably debdiff it and uncover my betrayal. And third, that would make my malicious package enter the unstable distribution. Were I looking for a real foothold on a large amount of computers, I'd have to wait probably around two years until it reaches a stable release.

That's why I said "thousands" and not "millions" :-)

Interesting thing you mention. Well, our migration was prompted by some theoretical advances; if you look at our slides at DebConf14 you will see some references to papers presented at the EuroCrypt 2012 conference talking about the relative strengths of different keys.

I don't contest that Zimmerman and Koch know how to communicate securely and what it takes, but maybe we are talking about a different threat model. One thing is identity assurance just for the sake of identity assurance, but in Debian we use it as a core infrastructural part: Get hold of my GPG key, and you have potential root access to thousands of computers. Of course, there are human checks in place, and it's quite unlikely you'd get away with yours... But it's possible.

I am absolutely not surprised by this: A well-known kernel hacker has enough systemwide understanding for the ocassional glitch to become obvious. He also uses most probably a very specific subset of programs for his day-to-day activities — I (a very far cry from his skill levels) haven't changed my main tools in over ten years. I mean, a tiling window manager, Emacs, a browser... Specific little tools can vary, but they won't jeopardize my system's overall behaviour — This means, it won't mean me spending time head-scratching to keep working.

Now, a developer is a far cry from a systems administrator. A sysadmin values stability over all things. I don't want a random upgrade to become a lost hour understanding the new configuration format of foobard.

And of course, casual users... If my wife desktop had changed from GNOME 2 to GNOME 3 without me preparing her, I'm sure she would not have appreciated it.

America is swamped already by illegal migrants. Some of them started arriving in the XVII-XVIII century. We failed to protect the borders of our great, glorious nation — And yes, they overthrew us and reducted us. Nowadays, the USA is flooded with all those dirty white do-no-goodies. They walk and drive around what used to be our forests and plains, as if they were the lords of the land. And they now don't want to allow any further migration After teaching us that migration was just a natural phenomenon, after telling us that Europe is overcrowded and they needed to pursuit the Great American Dream... They want to deny that same dream to newer migrants...

YES. YES, completely with you.

Language and literature are not directly marketable. Highschool-level algebra is not directly marketable. Biology, physics and chemistry are not directly marketable. Same goes for geography, phylosophy, history, and basically every other subject we learnt at high school.

Still, it would be absolutely foolish to get rid of all that.

We don't send kids to school to make them marketable — We send them to get a general culture, to get a baseline of education in all major areas of knowledge. And, of course, I will argue over and over that nowadays the basic workings of a computer are as central to understanding our world as algebra.

So, yes, forget about marketability. Think about getting enoug foundations to understand the world and society they will have to develop in.

Back in 2009, I was at the Debian Conference (DebConf) in Cáceres, Spain. We had the presence of two blind Debian Developers, Sam Hartman and Mario Lang, both of which have continued to attend the conference at later editions, and are today very active project members.

They gave this talk on how they use their computer — Completely different ways, both very interesting to appreciate:

I don't live in a communist state (I live in Mexico), but you will find some of the line you quote applying here — Sadly, every time less. The national government is the sole owner of strategic areas, such as petroleum, electricity generation and distribution, water extraction and distribution. some other areas, such as mining, are operated by concessions: The State is the sole owner, but specific companies can bid for the right to exploit it for a given amount of time.

And yes, the current trend in government goes quite against this. Our last decades' governments have excluded or dilluted many areas from this monopolic aspects.

You will find, however, this line is not clearly defined among different countries. There are many countries in Europe and Latin America where the areas I mention are under different government-owned and/or government-operated schemes. And the ideologic moments do shift from time to time: Ten years ago, Bolivia was privatising everything. That even led to what they called the "war for water", a revolution that outed a president. Today, they are again nationalizing resources. And while still a strongly underdeveloped country, they are faring much better and much stabler than in their past many decades.
