    The difference in the way of thinking is simple.

    Mathematician: "This is too complex for my brain. I can grasp the outer layer of the problem, but the underlying thing is beyond any human's capacity."

    CompSci guy: "Oh, I can write a program that handles the outer layer of this problem; I have no clue what that underlying thing is but I bet it can be brute-forced."

    Yes, it would - given a theory fully consistent with the observation without the "god-like" dark matter. Which we don't have.

    So until either a workable alternate theory is developed, or we manage to disprove Dark Matter through other means (e.g. discovering it's not actually matter) it's there to stay.

    aaaand quite a few of them don't even contain metadata that says what camera they were taken with so you have to pull down the right one from a menu, and in certain cases guess what camera the photographer used.

    I could understand an editor who wouldn't want to deal with this crap.

    But in this case it's a bit different. The photographer sends you a nice JPEG. And you say "nope, it was made from RAW with Lightroom, we don't want it. Send us the JPEG your camera created directly."

    Interesting idea but faulty like hell. The photographer took some important photos in poor lighting condition. The JPEGs came out unreadable but he was able to restore the content by processing the RAWs. Nope, don't wanna.

    The photographer spent three days in war zone, evenings in the bunker spent developing RAWs of what he took during the day. Finally he gets a courier to deliver the SD card to his contact out of the war zone and send it to Reuters. Nope, these were obtained from RAWs, we don't want them.

    Someone finds a camera near the body of a dead climber, the contents are RAWs the climber took. Not kosher though, no original JPEGs, GTFO.

  9. Re: Is a JPEG at 0% compression a RAW image? on Reuters Bans RAW Photo Format (petapixel.com) · · Score: 2

    To answer in a more technical way (than "use ImageMagick").

    JPEG encoding inherently can be completely lossless. 8x8 pixel squares of pixel values are converted to 8x8 matrices of frequency components - transforming the representation of data as a superposition of specific sine waves of fixed set of frequencies and parametrized amplitudes. Due to small area and range of values being covered, this mapping is lossless - the data is sufficient to recreate the exact image, errors of the "floating point nature" of sine waves being less than 1 bit of value representation.

    Then, depending on the settings of the software - the "compression rate", the parameters of lowest values and of highest frequencies are replaced by zeros. The "quality" parameter decides how many, and how significant ones. Unlike with direct value function which would leave black pixels, with sine waves this leaves the characteristic "artifacts" of JPEG, a kind of wavy imprecision along any sharp edges, some colors being misrepresented etc. This is not very visible to human eye, and you can get away with zeroing half and more of the parameters without significantly altering the perceived image.

    And then this is compressed using a standard lossless data compression.

    The gain comes from the fact that strings of zeros, repeating zeros and such compress very well - much better than "random" data of standard image.

    Of course if you don't strip any zeros and keep all the values, JPEG will be lossless and you won't gain anything size-wise, the compression being equivalent to standard lossless ones. And still you can lose relative to RAW, because the original (input) data uses 8-bit color channels, so 3 8x8 matrices of bytes per one "block". RAW can keep much more bits per pixel.

  10. So, IRA terrorists immigrated to Belfast from some country 2000km away?

  11. Do any of the adapting immigrant groups having Jihad/Holy War as a part of their culture? Did they reject it due to cultural adaptation or did they rather arrive without that concept in the first place?

  12. Note how none of them have in their tenets of faith how death while killing infidels will bring them paradise.

    They didn't adapt because their culture shuns yours. But they don't commit terrorist acts because their culture doesn't encourage doing so.

  13. Yeah, the Native Americans have quite seamlessly blended with the society. There are certainly no more racial/cultural issues with the Black, the ghetto districts just don't exist. And the peaceful Amishes have embraced the progress and are indistinguishable from any common American.

    By the time a junkie on a high from a bad batch goes on a killing spree and murders everyone in a local school. The bad batch went through because it would reveal the antenna was compromised if it was stopped.

    Not long afterwards the cartel boss begins suspecting the antenna was compromised anyway and moves the communication to different media, vanishing without a trace. Also, drugs are flooding the streets and the smart cop's daughter dies in a drive-by shooting between the cartel's men and some dealer.

    All because the smart cop wasted too much time letting it slip, all in hopes of catching the big fish.

    The "refugees" adamantly refuse to behave like normal people though. They aren't trying to escape the hell in their home country - they are bringing that hell with them in attempt to leech the West for welfare support. Their desire to attack us doesn't seem to wane any over time, just opposite - they grow increasingly angry that WE don't adapt THEIR ways, that countries don't agree to create districts with sharia law, that they shun inhumane treatment of women, that they demand tolerance to other religions.

    We've given that strategy a try and it has failed. You just lack enough first-hand info on how badly it failed and keeps failing. These people simply don't accept compromises. Their way or highway. And if the infidel suckers are willing to give them money for free, all the better, but that only means the infidel suckers deserve even less respect.

    They fine-tune most of the maps, and the maps comprise most of the game data. They are constructed in a way that doesn't allow for small diffs; a tiny adjustment in a map means the map needs to be replaced whole - and as they keep balancing the game by means of changing the maps (it is a difficult task as the maps are hardly symmetrical but they are meant to provide the same chance to the teams starting on both ends) they are updated almost every time.

Why provide a solution that supports 100% of playerbase flawlessly and pay for it if you can provide one that works for 90% for free and give a half-assed cheap workaround for the rest.

    "alive and well" to a degree - the more economically oriented a country, with more influential corporations and big financial entities, the deader the democracy. There are the banana republics where dictatorship barely disguises the corruption, and there are the 1st world powers where the corruption is well hidden behind the show of "democracy". The situation is best mid-way between, like in Iceland or Greece, where the governments actually represent the nation, but swing either way, towards authoritarian rule or economical oligarchy and it's getting corrupted badly.
