The thing is USB doesn't have DMA. This is on purpose, it allows for cheaper devices and is more secure. However it means everything has to go through the CPU. So higher load, higher latency. Thunderbolt is just PCIe (and display) so it is as low latency and impact as a card in the system.

For lots of usages, the difference doesn't matter, but for heavy hitting stuff it can.

I'd rather get something less likely to have issues, like a PCEngines box running Monowall or a Edgerouter Lite (which I did). More powerful and more open.

I just find it funny how people seem to think that loading OSS firmware is some magic prevention that'll keep the evil NSA away (like they need this exploit to spy on you, they'll just monitor you at your ISP). No, not if you believe the router companies are complicit in implementing it for that purpose. It'd be much easier to just go lower level.

If you presume that a backdoor like this is intentional, and is there for some nefarious purpose like the NSA or something, they can just move it to the chips themselves. The code that runs on on the CPU is only one small part of what goes on in there. It would be very easy to have code baked in to a chip with a backdoor that couldn't be removed or altered by the OS, because it is lower level.

So don't assume an OSS firmware gets you out of trouble.

Most people who say "Oh it is selfish not to have kids," are jealous. Kids are a big commitment, you have to trade off a lot to have them, at least if you are going to be a good parent. Now there are benefits, of course, it can be extremely rewarding emotionally. But there are tradeoffs and some people don't like them. So they see childless couples and see all the extra money and time they have and get jealous, and thus hateful.

It is, in fact, not a selfish position. It is a very pragmatic one. If we are to have a sustainable future, we need population growth to level off. Now I suppose we could go about it all draconian like China and force people to have a certain amount of children. However a better solution is for people who don't wish to have children to not do so. That allows those that want to have more children to do so and yet maintain a consistent population level.

Or even worse "crypto-anarchists" which is what this guy calls himself (no I don't know what it is supposed to mean). They don't really think through what Anarchy would mean, what it would entail, nor do they look at history and realize that Anarchy quickly becomes a chase where the strongest rule. No, they just think it'll be magic and pixie dust without a government. Everyone will be free to do what they want and the world will be an amazing place.

They don't see government as creating order, they think that it just happens magically and government just gets in the way.

Seriously, if you ever talk to someone that thinks they are an Anarchist you'll discover that either they:

1) Don't understand what Anarchy is, and actually want something else.

2) Have very poor knowledge of history, sociology, human interactions, law, and well, pretty much everything. They like the idea of Anarchy because to them it means they can do whatever they want and they really haven't considered the ramifications much further.

You don't find any that have a well reasoned and carefully thought out position on it, because it is the kind of thing that you quickly figure out doesn't work.

I see that all the time in IT with people wanting to cowboy up solutions cobbled together from a bunch of random shit. Yes, you can do that, and it can be made to work. However how much time will it take to do and support? Because unless your time is free, you need to factor that in.

Labour is a big part of the cost of pretty much anything you buy. Software is the ultimate example. The materials and distribution cost of software is minimal even if done on physical media. However that doesn't mean it is free to produce. It takes a lot of labour, in the form of programmers writing the code, QA testers reviewing things, support staff, and so on, to make the product happen.

Physical devices are no different, they just have higher materials costs. However all the labour cost is there. People had to design, build, test, etc, etc, that product and they all need to be paid since they all like to eat, have a place to live, and all that jazz.

There are all kinds of people, you can see them here on Slashdot, that know fuck-all about materials science and think 3D printers are magic. They think they are universal constructors, replicators, or whatever other sci-fi tech than can make anything and everything, just in a primitive form. So they think they can advance from playing with plastic to making metal parts that are as strong as forged metals and electronics and so on.

This is, of course, absurd. Anyone with basic MSE knowledge knows that there's a big difference between what you can potentially extrude using a process like a 3D printer does and how you have to make other various materials. It isn't as simple as just printing metal (which I've no doubt we'll see soon), not all metal processes are created equal.

So he doesn't know what he's talking about with regards to materials, which is why he thinks he's such a visionary, and he also knows fuck-all about anarchy. He's one of those loons that thinks an anarchy with no government control would be some kind of utopia instead of what it actually is, a place like Somalia run by warlords.

It all makes me laugh anyhow since he's in the US and could just go buy better parts over the counter anyhow. Oh wow, you can 3D print a lower receiver for an AR-15 that breaks after a little bit. Neat. Or you could just go and buy an AR-15 lower milled from an aluminium billet that will last several lifetimes.

Reading and comprehending posts isn't your thing is it? You just like to skim and then jump to conclusions to try and support your narrow world view.

I noted that my sister has no trouble, she has a generous grant (a scholarship if you like, but it works a little different) and her expenses are handled. However I have a full understanding of what those expenses are, and that they not paid for all students.

So maybe more reading, less jumping to conclusions.

If you like Ubiquiti you could look at their Edgerouter Lite. I'm real happy with mine. $100 and it'll outperform monowall and pfsense on way more expensive hardware. With a basic NAT setup, plus SPI firewall (the basic "permit established and related, drop others" rules) I've measured it at over 500mbps throughput. It probably would do faster, it's CPU wasn't fully loaded, that is just as fast a test server as I could easily get to.

Now of course it is more on the routing, less on the firewall n' such so if you need powerful firewall config, it isn't as much your thing (and won't get as good performance). If you load it down with too much stuff it'll slow way down, particularly since part of its speed is derived from hardware acceleration on its chip, so if tons of stuff is hitting the software it won't be as fast.

Just another option to look at.

In terms of the realtek chips, ya it sucks but it is what you get for the price. Intel NICs are expensive, because Intel knows they are worth it. They charge more for their chips than other vendors by a good bit, so you don't see them in cheap solutions.

In a lot of the EU, students from other EU countries don't have to pay tuition fees. Foreign students? Not so lucky, and language doesn't matter. If you aren't from the EU you pay increased fees. For example in Sweden you pay about 15,000 EUR/year for a science degree. In terms of language, you have to already demonstrate a proficiency in English and Swedish just to be able to get in.

Also all of this assumes you can get a visa and get admitted. People from other EU nations, no problem, you can live and work anywhere in the EU, that is a big part of what the treaty means. Non-EU individuals have to get a student visa, the requirements of which vary.

And of course none of that deals with the cost of food, housing, transport, etc. You are on your own for that, barring a scholarship.

This is a subject I have more than a passing familiarity with, as my sister is currently working on her PhD in Europe (at two universities, one in the EU one outside of it). She got a generous grant that pays all her tuition, living expenses, and even some extra but that isn't what all students get. It wasn't as though she just walked in and said "I'd like to go to school here," and they said "Certainly, please come for free!"

Also she even had an easier in than many: She and I hold Canadian citizenships. Canada is a commonwealth country and England is in the EU so that makes a lot of the visa shit way easier than it would be for an American, not that it wasn't still a big production.

It is exceedingly narrow-minded to suggest that an American should just "Emigrate to an actual civilized country instead of a pretend one," for school, as though such a thing were trivial to do and people only did not out of ignorance (not to mention the misplaced cultural supremacy of the statement). No, it turns out that you can't just graduate from an American highschool and say "Well screw the US, I'm off to Europe!" and walk in and go to school for free.

Grad school was historically and is supposed to be the sort of thing not everyone does. It is for people who are really interested in a field, who want to start doing some original research (under the umbrella of a professor's overall research) and so on. The sort of thing only for those that are truly interested in pursuing the subject more deeply and pushing the boundaries.

Also most fields don't require graduate degrees. There are some that do (like lawyers), though usually they require a PhD or other advanced degree after it (like professors, medical doctors, etc). However for most an undergraduate degree is all they are after.

However where I work, I see a ton of students that go in to grad school that are hoop jumpers. They see it as the next thing, that will get them a better job. They aren't that interested in the work, and don't have a particularly good understanding of it. They take comprehensive exams instead of doing a thesis, and so on. They try and use more time in school to make up for a lack of talent.

So, if you are thinking of grad school, and it'll be any kind of financial hardship ask yourself: Why am I going? If it is because your field requires it, then ok no problem. Gotta do what you gotta do. If it is because you really love the field and you want to go to a higher level, that's good too, but just understand it'll be a pain financially. If it is "because I'll get a better job," then no, stop right there. That's not a reason to go to grad school, particularly if it is going to be a problem financially. It probably will NOT get you a better job, and will just give you more debt.

So if I just show up in a European country, they'll let me go to university for free? Hint: No they won't.

My sister went to Europe for her PhD. She didn't end up paying... because she got a generous scholarship. That also was what allowed her to get the visa to go. She didn't just show up and walk in to a university for free.

Same way it would have worked in the US or Canada, actually. If she had been accepted to a program with a generous scholarship, well it would have been free.

Go to Canada some time, one of the US's closest allies. You'll find that you can travel to Cuba freely, buy Cuban goods (cigars being the most prominently advertised as being of Cuban origin) and so on.

The US is the only country that clings to an embargo and it is purely a face-saving maneuver, not wanting to admit it was a bad idea and hasn't worked to unseat Castro.

However for all that, Cuba is still poor... So sorry, you can't blame the big, bad 'ole US for this. Their policy is not helpful, but it isn't why Cuba is impoverished. That lies at the feet of their own government.

So the US won't trade with them. Ok, but while the US is a large nation, it isn't the be-all, end-all. Canada, the EU, China, Russia, they are all perfectly ok to trade with Cuba. So Cuba has access to most of the world for trade goods. Yet, they still have an extremely low standard of living.

Sorry, but the US boogeyman thing doesn't play, not in this day and age. Cuba has a large responsibility for the problems in Cuba.
