    Cancer isn't some magical disease that turns up. It's literally coding errors (for the most part). If you want a computer analogy, it's like expecting an hard drive as old as you are not to have any bad sectors - it's possible, but it ain't gonna stay like that forever. And if those errors are in the wrong places - the whole thing becomes a mess that destroys itself. Of course, a lot of the time those errors go unnoticed for decades or even forever if they are in an unimportant part of the code. And there's a certain amount of "error checking and correction" going on in various reproductive processes of the cells that lessens the impact.

    Cancer is, basically, the MTBF of a human. If something else doesn't get you, cancer will eventually catch you up by sheer random statistics - enough time exposed to the sun (not even in a sunny country, or deliberate exposure), or a million and one other factors (which is why *everything* is stated in the news as "causing cancer"), and the cell's DNA "bits" will flip and it'll go crazy and stop all its highly-evolved self-limiting processes until it starts to take over your body. With some people it happens within their first year of life, some people live to 100 and never see it... but live long enough and you'll get cancer.

    You can extend life, you can treat cancer, in theory you can "cure" it (i.e. push its statistical error rate outside the lifespan of a human) but it'll always be there. Try and find someone who's lived past 40/50 and hasn't had either several friends/relatives or themselves have it / die from it... we've all been there. I can name five serious (two fatal) off the top of my head just from blood relations and I'm only 30 - and those are just the ones I know about.

    Cancer isn't a brake on population growth - the genetic factors are rarely subject to natural selection as others have pointed out - it's just the natural lifespan of a human. We didn't have it very much a few thousand years ago because we weren't living long enough for it to have a big effect. In the future, it will always be there even if we "trick" our way around it (there are animals that live longer than us and don't see such a high rate of mutation). Just look at the primary methods of treatment for a condition which sinks billions of pounds of research money - surgically cut it out, poison it or nuke it.

    Pulling some stats from the wiki: Cancer causes 13% of all deaths worldwide and 25% of all deaths in the US. More than 30% of cancer is preventable via avoiding risk factors (which suggests that 70% of it is not preventable at all). It's a statistical function, not a disease, and the more exposure you have to things, the more your chances go up (but, some would argue, the more your quality of life would go down). Nothing brings those chances down below their base rate, though. It can be made more survivable, less painful, less affecting, but you can't "stop" it. Change your lifestyle and you have more effect than researching drugs that few can afford, won't be effective and will have terrible side-effects - the story of all medicine ("Since 1971 the United States has invested over $200 billion on cancer research... Despite this substantial investment, the country has only seen a five percent decrease in the cancer death rate in the last 50 years"). Who here wants to give up alcohol and sex and modern living to live longer? I would guess few. Same as everything else on the planet: Live life, enjoy and if you exercise and take care you'll extend your average lifespan. You could still get cancer tomorrow, though.

    Cancer is what you're left with if you've survived everything else. In the brutal, inhumane terms of statistics, it's not very important in terms of sustaining the planet / population or anything else.

On Linux, that's just bog-standard iptables doing its job the same as ever.

    I don't expect anything non-SSL to be secure by default. I treat it as if I was using Tor in that respect. Make sure you have Gmail or whatever set to "always use https". If you want anything better than that (i.e. email, IM, http, etc. traffic), or better assurance overall, you have to have a VPN to be safe.

    My OpenVPN automatically deletes other routes except for the essential ones and adds a default route through my VPN interface so when connected to home I *know* everything has to be using the VPN to communicate in that instance (hate the idea that if OpenVPN dies, there might be "another" route lurking which sends things out on another interface - I've seen it happen with some "automatic" configurations on Windows).

    I often game over an OpenVPN instance, even when playing locally, so don't take heed of the rubbish about it being too costly in latency terms - of course, if you are in a foreign country and relaying to another, it will lag, but the actual overhead is not much worse than just ordinary IP routing to your destination.

    Basically - SSL in some form or another, whether that's direct or over a VPN... otherwise you cannot trust things. Of course, millions of people trust ordinary wifi points all over the world, all day, every day. If you decide to follow their lead, that's up to you.

    Alternatives to a particular name are always welcome - everybody likes an alias, it just aids learning by providing choice, but that's a particularly horrible example, that's all. I literally had to read the whole program to work out what that "return" was because I was trying to interpret it as a function return or keyword. And I noticed that I found the use of && and & quite odd, but maybe my brain wasn't into it. "return" is ambiguous (newline would have been better, possibly?) and confusing. Though why it's even necessary to return-space a set of strings in order to sort them is another matter entirely (it suggests to me that strings are inherently unbounded, but I doubt that would be the actual case).

    "At least you agreed that with zero previous knowledge of the language, you could "already see what the code is trying to do." I think that would be true for even non-programmers, and is a testament to the self-documenting strength of revTalk."

    I'm a programmer (not professionally but I program as part of my job and in my spare time)... that means I can tell what code is *trying* to do just by the names of functions and outlying structure, even if I don't know the language. If I'm brutally honest, it took me longer than most with this language and if it hadn't been for the variable with "anagram" in the name, I would have been stuck. I don't want to push that down to say that *all* novices would do the same, but I would find it highly unlikely a novice programmer could understand that code at all, and one would need several weeks/months of using Rev as a first language to even get close if they'd never programmed before.

    Last month, I taught BASIC to a 15-year-old (who was into "old" computer stuff but had never programmed, so I just demonstrated the concept of programming using BASIC) in an afternoon. He came back the next day with a game he'd written - and we're talking old-fashioned "I want a dot here, a letter ther" kind of game, not some DarkBASIC template. I don't claim that BASIC is "good" or easier to learn, but the point was that the structure of a program (including subroutines, program flow, variables, keywords, etc.) can be taught in an afternoon to the point that someone can replicate it and understand it. However reading *that* program would have given him a lot of trouble in this language, even if I'd started him on that. Damn, even I struggled to find meaning and separate variables/keywords/structure.

    "The main idea here is that revTalk appeals to people who are not keen on traditional programming languages. It can therefore enable them to accomplish things they wouldn't normally consider trying, either because of the expense or time involved."

    And... Yeurk. That might be more readable to some people but I think I just lost some braincells.

    First, the use of the word "return" to mean, in this case, line return. Nobody I know calls them line returns except established programmers (i.e. those who know the historical difference between carriage return and line feed), and people who deal with typography in some way. Return actually *means* something in 99% of programming languages, if not as a keyword than as a name for a particular program flow.

    And it reads like someone "pronouncing" pseudocode or some kind of BASIC. I don't see how this line is *at all* intuitive:

    "if c is not in sourceWord then filter wordList without ("*" & c & "*")"

    It was fine right up until that last bit, which could have a billion different interpretations. I assume it's doing wildcard removal of anything that doesn't have the character c in it but, hell, that's just because I can already see what the code is trying to do.

    The syntax is *too* loose, so loose that you will stray into incorrect meaning by accident. Possibly it's more "readable" to a novice, but they probably aren't aware of the subtleties of exactly how it could go wrong, by a simple mis-wording or instruction-order-problem. I can read code and think "Yeah, that'll work" when in actual fact if you look closely, there are critical errors that turn it into gibberish. A novice might be able to read that code, but if they could know for sure whether it did what they want without unintended side effects is another matter.

    And it seems *very* long-hand. Too much, in fact. I'm now stranger to lines of code that need to be wrapped because they hit the column limit, and in this language it seems even more likely to occur.

    50 or so lines of BASIC with a simple comment every now and then would do the same job much more "intuitively" to me. And I've taught many people programming in my time (I taught most of my school's programming classes when I was supposed to be a student of that same class!), from scratch. That language is truly horrible and no better than any other. Sure, once you're used to it, and if it was your first language, you'd think it was "good", but... no thanks.

    "4 million passwords per second" is, as has been established, bullshit for anything other than plaintext "is this the password" checking. Any sort of encryption will kill that rate down to a more sensible number (and multiply up the time taken) because decrypting, even with a known password, is dependent on the encryption scheme used and can run into hundreds or thousands of individual instructions.

    And that's assuming that there *is* a simple check that will say "Yes, this is the right password." Guessing a password and checking against a known MD5 hash is a LOT different to checking whether you've successfully decrypted an encrypted file with unknown contents. If the source was an EXE, then you could decrypt with a password, look for "MZ" signature, etc. If it's a zip, or a jpeg, or a disk image, or any other of the several hundred plausible filetypes, then you've just multiplied your decryption time - by several factors. Now not only do you have to generate "the next random password", you have to perform heavy decryption operations to get out the decrypted texts and analyse a tiny portion of the encrypted file before that particular thread can move on to another password.

    And then multiply that by the "longer password" factor and you start hitting stupidly impractical time really, really quickly. The point was to highlight that even "months" of decryption time is an ideal scenario with factors working in your favour (e.g. known plaintext to know when you've successfully decrypted). Without that, you really, really start adding time on quite fast. And, in fact, anyone even *bothering* with encryption to avoid incrimination is really going to have done it properly, or they'd be caught out by other traces.

    Encryption is still in use for a reason - that one entity with even several thousand processors which are ideal for decrypting things would still take *decades* to decrypt even a simple message.

    Assuming you can brute force it that easily and not, say, have to deal with any CPU intensive encryption/decryption process for each password. And that he only used 8 characters.
