Ask Slashdot: VPN Setup To Improve Latency Over Multiple Connections?

JackDW Re:Actually, it's easy. (174 comments)

Do you know, you're the first person in this topic to actually answer the question? Most others missed the VPN part.

OpenVPN already knows how to discard duplicates and retransmit lost packets. It's a lovely way to build a semi-reliable network on top of an unreliable one, and very hackable.

The questioner only needs to modify OpenVPN (on his PC) to send its UDP packets via two different routes. He should configure his VPS to have two public IP addresses, with OpenVPN (server-side) bound to both of them, and then manually adjust the routing table on his PC to force the use of a specific route for each of those two IP addresses. The hard bit (and it's not really that hard) is making OpenVPN (on the PC) send each packet twice to two different IP addresses, which would require modifications to the source code and some familiarity with the sockets API.

I think it would work, not just for Battlefield but for anything. And it sounds like fun.

Actual Results of Crimean Secession Vote Leaked

JackDW Re:Again? (557 comments)

I don't believe this either. There's no corroborating evidence, not even a screenshot (though that could be trivially faked).

This is a conspiracy theory and it's as nonsensical as thinking that Bush's "people" accidentally leaked "the truth" while they were supposed to be covering up "the facts" about 9/11.

Take note of the names of the Slashdotters who automatically believe this sort of thing, and give their opinions an appropriate level of credit.

Mathematical Proof That the Cosmos Could Have Formed Spontaneously From Nothing

JackDW Re:If you make this a proof of God... (612 comments)

Hmm. Experience suggests the intelligent beings would stare at the 0.0001% and either deny the evidence for it, deny its relevance, or try to destroy it. Inconvenient facts are inconvenient.

How the Internet Is Taking Away America's Religion

JackDW Works both ways (1037 comments)

I became an atheist when I was about ten or eleven years old. I was sure of myself at the time.

Twenty years later, I have some serious doubts about it, and have retreated to agnosticism. That's partly because the Internet has given me easy access to all sorts of information about philosophy, religion and politics. I was able to read what the other side actually thought, not what my side said they thought.

I could say that the Internet destroyed my faith in atheism, but I know that you guys really hate the implications of statements like that, so please take it as a (trollish) joke!

What I would say, not as a joke, is that the Internet has not stopped people believing weird and/or stupid things. In fact it has strengthened all sorts of weird beliefs, some weirder than anything in the Bible.

Non-Coders As the Face of the Learn-to-Code Movements

JackDW Re:Am I the only one.. (158 comments)

It's not a worry. A company that would hire cheap, bad "programmers" is not somewhere I would want to work anyway.

Non-Coders As the Face of the Learn-to-Code Movements

JackDW Re:Am I the only one.. (158 comments)

But Zuckerberg and the other industry leaders don't want programming skills to be valuable. They want programmers to be cheap and easily replaced, like unskilled workers in a factory. The "year of code" is not for the benefit of school children, or programmers in general. It is for the benefit of the upper management of major corporations, who live in hope that good programmers will one day be cheap.

Imagine that instead of the "year of code", it's the "year of football". The government notices that the England soccer team is not very good. The soccer industry finds that good players are really expensive, and wishes that it could recruit a few more good players straight out of school while they are cheap. They get together with this initiative called the "year of football", with the aim of (1) reducing the cost of employing good football players, and (2) improving the performance of the national team.

The immediate result is a massive investment: a soccer coach for every school, extra soccer lessons, one football to be provided to each child and so on.

But of course it achieves nothing, because the children who love playing football are already playing it in their spare time. The impact is only on the children who hate football and don't want to play it. They are forced to take part in this boring activity, developing skills they don't want in order to play a game that they don't enjoy. They come to hate football even more than before.

And, because the children who love it are forced to play with children who hate it, this ruins the subject for everyone. They all hate having to learn about basic stuff like how to pass a ball and how to tell if someone is off side: the good players already know this, and the others don't care. Meanwhile the schools spend less time teaching general subjects that are widely useful. Everyone loses.

UK Govt's Censorware Blocks Tech, Civil Liberties Websites

JackDW Re:Useless Article (148 comments)

I see what you're saying, but here's how I think that would actually play out.

If this gets further than Slashdot and Reddit, the government's PR will point out the nature of the mistake, and there will be articles on the BBC News about how a blogger got it wrong and the whole thing went viral before anyone checked any facts. Which is absolutely true.

But next time - when there really is some censorship, when Amnesty International really is on the blacklist - the government's PR will say that once again, it's a mistake, and once again, the bloggers are looking at some ISP's opt-in whitelist rather than the real thing. Meanwhile they can quietly correct the blacklist before too many people notice, making it look like (once again) the Internet has cried wolf.

However this goes, they win. The best thing for us to do is take the high ground, and be absolutely truthful about what's going on. Yes, obviously, this on-by-default filtering idea is stupid, staggeringly bad even for the Tories, but we're not going to deal with that by playing amateur PR against resourceful people who do it for a living.

$39 Arduino Compatible Boardset Runs Linux On New x86 SoC

I think it sounds quite good, but international shipping is $35.60, nearly doubling the cost.

$39 Arduino Compatible Boardset Runs Linux On New x86 SoC

JackDW Re:wow its a vortex board (95 comments)

That matches my experience with a similar Vortex x86 CPU. It was 486-compatible, but Pentium-specific instructions such as RDTSC were illegal. I had to compile a custom kernel, and make sure that all the userspace libaries and programs were 486. But this was no big deal. You always have to do things like that for embedded development, and it's usually a lot more hassle for an ARM-based platform because of the higher degree of variation.

I'd also expect it to run older versions of Windows, though XP may be a stretch.

First Cases of Flesh-Eating Drug Emerge In the United States

JackDW Re:Gross, but... (618 comments)

Gladly: More crime. Poorer grades in school. Higher unemployment, lower employability. General decline in public health and living standards. The emergence of neighborhoods where nobody would choose to live. Large numbers of cases of child neglect handled by the police and social workers.

Not good things. But these are the results of non-enforcement of drug laws. If you look for the evidence you will find it, and if you really want specific examples of places to look, then I can tell you about those. Really, science is not on your side here.

First Cases of Flesh-Eating Drug Emerge In the United States

JackDW Re:Gross, but... (618 comments)

"Legalize heroin to prove me wrong"

Some proof. It would not be a controlled experiment - the results would not be useful.

We would simply end up arguing over the statistics. You'd say that fewer people were dying of overdoses - your criteria for success. Whereas I'd point out that society was damaged in other ways by the large increase in drug use that would inevitably follow legalization. Nothing would be proved either way.

Case in point is, well, anywhere that any drug has been decriminalised. Some people say things are better, and others say they are worse, and both groups have some evidence to support their claims. Personally I would recommend not forcing radical, uncontrolled and potentially dangerous experiments on living people without their consent, particularly when the results are worthless, but then I'm one of those awful people who thinks that drugs should probably not be legalised, so my opinion hardly matters.

5-Pound UAV Flies For 50 Minutes, Streams HD From Over 3 Miles

5-Pound UAV Flies For 50 Minutes, Streams HD From Over 3 Miles

JackDW Re:Bad guys (115 comments)

That would be a flaw in the plan, if the plan were to kill people. But it isn't. The plan is to turn them into passive supporters of the regime, unwilling to offer any resistance, and quite possibly unable to comprehend why resistance might be important.

5-Pound UAV Flies For 50 Minutes, Streams HD From Over 3 Miles

JackDW Re:Bad guys (115 comments)

Now you mention it, "the ravings of a drug warrior" actually is a pretty good description of Huxley's "Brave New World"...

As an evil dictator I would not particularly care which drugs people took, or what they believed about the safety of those drugs. From my perspective, the effect would be the same - the people who might otherwise have resisted my power would happily stay at home instead.

5-Pound UAV Flies For 50 Minutes, Streams HD From Over 3 Miles

JackDW Re:Bad guys (115 comments)

Not mutually exclusive. As an evil dictator, you can do both. Take away real liberties and real rights for "security", and simultaneously grant the freedom to take drugs. It will be easy to fool the people into thinking that they are getting a good deal here.

5-Pound UAV Flies For 50 Minutes, Streams HD From Over 3 Miles

JackDW Re:Bad guys (115 comments)

Hmm, seems to me that an oppressive government would probably start by legalising drugs. How better to control the population than by limiting their desire and ability to rise up in revolt? The best sort of slavery is voluntary. Why imprison the people, when you can get them to imprison themselves?

As an evil dictator, your first move should be to legalise as many drugs as you can get away with. This will win you a lot of popular support in the short term, and in the long term, the people who might have become well-educated and clever opposition leaders might instead end up as poorly-educated drug users with severe mental health problems. You may commence your evil laughter now.

'Hobbit' Creates Big Data Challenge

JackDW Re:it's the length of movies themselves (245 comments)

Well, I thought I was a Peter Jackson fan, but I guess I'm not, since real fans don't criticise.

I don't recall getting bored during the book at all. But I was bored during the film. It really dragged on. It's not so much the plot development and the story - those are fine. It's the action sequences. They are repetitive and interminable. Some of them could be cut out completely, while others could be significantly shortened, and the film would be better for it. There is a tradition of "fan edits" that make bad films better, c.f. "The Phantom Menace", and "The Hobbit" is in dire need of that treatment.

'Hobbit' Creates Big Data Challenge

JackDW Re:it's the length of movies themselves (245 comments)

"The Hobbit" needs a fan edit to bring it below the two hour mark. This should be easy for part 1, though the real editing challenge would be to do it for the entire trilogy. Tricky, but possible, because it's not a long book.

I much preferred the LotR approach of releasing shorter versions to theaters and then releasing long versions on DVD for dedicated fans.

Wayback Machine Trumps FOI Tribunal

JackDW Re:Must be nice (401 comments)

No, that's not quite right. Let me refer you here:

http://en.wikipedia.org/wiki/The_Establishment

The BBC certainly is part of the Establishment. But it is not part of the government.

I mention this because it's an essential part of understanding how our power structure works. Authority and privilege does not flow downwards from government. There is something above government, something more powerful than it, something which ultimately gives the government the authority to government. This we call the Establishment. It's the word you were looking for. But I don't know if this helps the argument you were making.
