    [A:] Never accept form data via GET, always require POST.

    Isn't it better to learn the actual environment? GET is the verb for retrivering information, POST is the verb for sending information.

    Use them acordingly.

    Those are not only not as advanced. They are not general actions (you can't really drag that file into anything, altough that is getting better with time), and are not scriptable.

    A commune (despite its name) / cooperative / partnership is a completely different beast from Comunism, as proposed by Marx. The most relevant difference is that the products of the commune / cooperative / partnership are sold in a capitalist market. While in Comunism, there would be no market at all.

    Yes, in local initiatives comunism works, and often is the best choice. When you try to push it further, it fails.

    Normaly (and on all real cases available) a web browser is slower than other GUI toolkits because it has to solve a plentora of other problems, not just showing things on the screen, and the toolkit can do just one thing. Besides that, software embebed on browser is written in Javascript, that is interpreted and again, normaly (and on all real cases available) interpreted languages are slower.

    But none of those probems must be this way. They just happen to be.

    Bit torrent works in that way: If we both participate on a torrent with a thrid party, odds are that I'll send part of the file to you and he, and you'll send part of the file to me and he, and he'll send part of the file to both of us. In the end, we colectively have three copies of the file.

    RIAA reasoning was that, in consequence of that they could ask for compensation for 6 files. Not exactly n^2, but assimptoticaly equal.

    Yeah, if you don't remember the specifics, the blue team won because the boats were prohibited to use the most efficient strategies.

  10. Re:Statistics on 2011: Record Year For Airline Safety · · Score: 1

    Getting statistics about aviation safety is one of the hardest things to do. Accidents are so rare that we indeed have no idea on how safe planes are. The ones we have an idea are already near the end of their comercial life.

    Funny fact. I was helping a friend to look at the statistics of accidents on brazilian airports by their sizes this year. The intent was to discover if operations on small airports could be made cheaper, while keeping them reasonably safe. We had 5 years of data, on 700 airports. One of the years there happened to be 2 accidents on small airports, what leaded to the conclusion that smal airports are already unsafe. Of course, after error bars, the conclusion was the normal "there is not enough data", not "small airports are not safe".

  13. Re:http://xkcd.com/936/ on Ask Slashdot: Changing Passwords For the New Year? · · Score: 1

    The set of words is ridiculously larger than the set of characters. That is why passphrases work, they use a larger basis, while keeping the exponent (number of things in you password) small.

    Some 5 dictionary words are enough to give you 64 bits of entropy in a large language (like English).

    Website users aren't the same as OS users.

    Most website developers don't even understand what a hash is. They are simply not capable of using hashes on their sites, even less to do some sane salting. Most of the top used development frameworks also don't help securing passwords, some even make them harder to secure.

    That said, I don't care about people harvesting the passwords I use on most sites.

    You mean, we can't point to people that hold strong oppinions despite lack of evidence and tell they are similar?

    In fact, the people of the Church of X are way more rational. They have no evidence, and won't ever. Making your belif despite conclusive evidence is quite more insane.

    You were likely going for a +5 Funny, so the fact that you are currently modded +5 Interesting is not your fault.

    Google and Firefox are not competitors. Competitors don't go buying each-other products. They are partners, recently Firefox tought they weren't getting enough from the partneship, so they used some negotiation skills, and got more. Google was happy to pay more (but they were even happier to pay less), so they agreed on some terms.

    But yeah, calling it charity is ridiculous.

  19. Re:Just wait until Iran blocks the Strait of Hormu on Prospects Darken For Solar Energy Companies · · Score: 1

    Smal steam engines are at the $1/W nowadays. The micro engines (less than 1MW) are more expensive than that (new from the factory). I expect the huge ones (more than 1 GW) to be cheaper than that already.

  20. Re:Just wait until Iran blocks the Strait of Hormu on Prospects Darken For Solar Energy Companies · · Score: 1

    You buy both solar panels and steam engines on watts, not joules. (As you do with automobiles, by the way.)

    Of course, they won't last forever, and they'll need some fuel (the PV's one getting for free after an up front payment, the coal getting at a cost, with nearly no up front payment). But most of the money goes into investiment into capacity (on both cases), so watts.

  21. Re:Usually IT and engineers battle on Justifications For Creating an IT Department? · · Score: 1

    IT approaches a system in terms of maintenance, engineering in terms of design. This is pretty obvious, as IT is focused on getting a system up and running for a long time, while engineering (and web design and software design) is focused on producing something or completing a project.

    Do you really think the engineers that keep the transmission running in a TV network don't care about maintenance?

    They are quite good at doubling their market share. In fact, just after you posted that they probably doubled it at least another 4 times.

    Nice for the news too: "Windows is the fastest growing phone OS!" or "Windows install base has just grown 16000% in a week". I just don't know what they will report when somebody actualy buy one of those phones. PR people aren't good dealing with infinite numbers.

    It is just a matter of creating something better, and people will adopt. The problem with calendars is that doesn't seem to be anything better than what we have. Different, yes, but other calendars just have a different set of problems, they don't really improve what we use.

    In fact, the question would be what did he need computer simulations for?

  25. I think it would be advisable to start with something 2D, that is simpler to understand and to code. On their first game the kids will have too much to learn, so not making them learn analitic geommetry, lightining, all the tools you'd need for 3D, and lots of other stuff (like "why is my game that slow?") is a good thing. First focus on general programming and basic I/O.

    Now, if you take that advice, you'd need a good library for general I/O that is available in a good language for novices. Well, here I can recomend Pygame, on Python.
