    No audio jack, huh? I guess that is a push to buy Bluetooth headphones.


    More likely a push trowards headphones using the lightning port, to manufacture devices using the connection you need to be certified by apple (at a cost obviously) and they take a chunk of every sale which when you consider any audio delivered over lightning will requires its own DAC, amp and DSP which is going to mean high costs is going to be a fair bit of cash. Plus the added bonus of being able to use the likely higher quality Amp DAC and DSP included by the headphone manufacturer to claim Lightning sounds better.

    posted a message on MP3 to AAC Effectively?
    Quote from ThaVrisco»

    Can I convert an MP3 file to an AAC file effectively?



    Yes but it would not be particularly wise to do so.

    Quote from ThaVrisco»
    Will the audio then sound better than when is was an MP3?


    No, converting from one lossy format to another is not going to improve audio quality in all likelihood you would see a reduction in quality from further compression.

    If you want to improve audio quality your best option is to improve your equipment rather than the files, even with lossless FLAC or WAV you would be hard pressed to hear any improvement over a 320 kbit/s MP3 (obviously lossless files are still useful for archival reasons)

    Capacity isn't everything.

    The quality of the internal components, the design, the units ability to actually cool itself (you would be amazed how many cheap designs just toss a fan on there and end up with poor cooling where it really matters) and its ability to actually provide that capacity consistently without falling out of the ATX spec matter.

    Crappy prebuilt systems generally come with crappy bottom of the barrel (or as near to it as possible) PSUs, this means cheap Chinese caps (rather than the actually perfectly good 2nd tier stuff from the likes of Teapo or Capxon), group regulation, (not inherently bad, but hard to do well, especially cheaply) a lack of AC line filtration, a possible lack of PFC (possibly even with fake concrete coils) and you will almost never get the labeled capacity out of them, the reason for this varies, it could be rated for a low temperature meaning its derating in an active system and cannot output full power as a result, it could be labeled for peak output or the labeled capacity could be an outright lie, all 3 are rather common in cheap units.

    posted a message on This power supply seems pretty sketcy, however, it's still a $58 CAD 80+ Bronze power supply

    Well its rated for full power at 30oC which is not a great start, the internal temperature on a PSU can hit double that, anything rated for less than 40oC is likely to be a bit on the less desirable side.


    On the plus side it is actually 80+ rated (you would be surprised how often units claim to be without actually having been tested) though it appears this design has not been tested previously which makes finding the OEM that bit harder, unfortunately they also have their own UL number on the unit rather than the OEM's which without an actual teardown leaves me rather clueless as to who exactly the OEM is.


    Output on the 12v is high enough, no obvious indications of a poorly modified ATX 1.3 unit, connectors are about right for the wattage (2 6+2 pins would be more typical than a 6+2 and a 6 and its 1 or 2 SATA down from what I would expect but thats not a massive concern on its own) a few of the newegg reviews complain about out of spec voltages, 80+ show voltages within spec (id wager its a bit of both).


    Without knowing what the internals are like and seeing a proper set of tests done its hard to say for certain but the unit doesn't appear to be bottom of the barrel awful at a minimum, probably safe as an expensive 400W for short term use but I wouldn't trust it with anything more.

    posted a message on Do You Think That Immortality Is Possible (If So, When?)
    Quote from LokiChaos»

    I have my doubts on biological/physical immortality. We can likely extend things to several times current lifespans (maybe even 10-20 times), but unless we develop means of swapping out parts things various bits are going to wear out (that still leaves the issue of ethical sourcing of replacement parts).


    That there is an answer for, (or more accurately a promising potential answer) Induced Pulripotent Stem Cells.

    See normally pulripotent stem cells are obtained from blastocysts, which have as you are likely aware caused some controversy and given the source cannot be patient matched, but in 2012 Dr Shinya Yamanaka (who revived the 2012 Nobel Prize in Physiology or Medicine for the discovery) discovered that it is possible to generate pluripotent stem cells from more differentiated adult cells so far the technology has yet to mature to a stage where they have been approved for human use however it is improving which means we may soon be able to generate patient matched organs for transplant which also eliminates the possibility of immune rejection.

    Yes Engineers, exactly the experts to consult with regards to human health.


    . The cause of aging is the shortening of telomeres on the tips of DNA, which occurs over time.


    The shortening of telomeres MIGHT have an effect on aging, no one knows for certain unless there is some as yet unpublished research which makes some more conclusive observations but as it stands its not looking terribly likely.

    posted a message on Are we in a Virtual Simulation (And other questions)
    Quote from funkyskunk1next
    Question I Do we live in a virtual simulation?

    A question to which an answer simply does not exist.

    Quote from funkyskunk1next
    Question II
    What is life?

    Something which exhibits most or all of the following traits:
    1. Homeostasis (Regulation of its internal environment to maintain a constant state)
    2. Organization (Being structurally composed of one or more cells)
    3. Metabolism (Both Catabolism [decomposing organic matter] and Anabolism [transformation of energy and chemical components into cellular components])
    4. Growth (maintainging a higher rate of anabolism than catabolism and increasing in size)
    5. Adaptation (the ability to adapt over time to environmental changes)
    6. Response to stimuli (often demonstrated by motion but there are obviously countless applicable responses)
    7. Reproduction (either sexually or asexually)

    As we understand it all life is composed of cells, this is not required strictly speaking but the idea is rather foreign as far as our understanding goes, an extraordinary claim requires extraordinary evidence, any claims of non-cellular life would require some serious evidence backing them.

    Question III
    What is the meaning of life?

    42.


    Quote from funkyskunk1next
    Question IV
    Why haven't we found extraterrestrial life yet?

    Numerous possible answers, there may be no other life in the universe, it may be too far away or have developed too recently for us to detect.


    Quote from funkyskunk1next
    Question V

    God?

    The earth's size (at least as an independent factor) is irrelevant to atmospheric retention (larger planets are more likely to have a greater mass and have an iron core allowing a magnetic field if rotation is fast enough but these features are not exclusive to larger planets), its the mass, core material and rotational speed which is important these values could be varied without issue, the earth's mass is sufficient to retain an atmosphere through gravity alone and it spins fast enough to generate a dynamo in an iron core producing a magnetic field which also helps retain an atmosphere, the earths mass is also explained (as is the origin of the moon) by the Theia impact hypothesis (which is itself far from perfect but is the current working model).

    estimates for the range of our star's habitable zone range from 0.5-0.87 AU on the inner edge and 1.01-3.0 AU on its outer edge with 1 AU being about 150 million kilometers even at the lowest estimates, 0.87 and 1.01 AU, the earth could be about 1.5 million kilometers further away or about 19.5 million kilometers closer to the sun and still be within the habitable zone as we understand it, your comments on the moon have a similar answer by no means perfect, nor are carbon, nitrogen etc cycles which are themselves at least partially a consequence of life on earth are also by no means 'perfect'.

    There are many many theories as to the origin of the universe beyond the big bang theory though that is obviously the currently accepted model, the universe may not even have an observable beginning or we could be completely wrong about its possible origins.

    With regards to the existence of a deity, believe whatever you want, just keep it to yourself and let other people do the same.


    Quote from funkyskunk1next
    Currently, the speed of light is 299,792,458 miles per second.

    First of all that's Meters per second not Miles per second (that would be approximately 186,000), that is also the speed of light in a vacuum, though say air for example simple light is about 299,700,000 ms-1, or about 90,000 ms-1 slower than in a vacuum, its slower still through glass.

    Quote from funkyskunk1»

    By observing quasars, which literally allow us to look into the past (Because light takes a while to reach us) John Webb was able to see that 6 billion years ago, the speed of light was faster than it is now. To change that would take a massive amount of raw power.

    As already pointed out simple light travels through transparent materials at different speeds, normally when returning to vacuum simple light will return to the speed of light in vacuum however as recently shown by physicists from Glasgow and Heriot-Watt Universities (Full paper here) more complex light (they tested Bessel and Gaussian beams) does not return to the original speed, slowing light is by no means trivial but its not as complex as you make out.



    Quote from pefannext

    lets be real here if we question anything there are flaws, for example the big bang theory which just happened one day and every thing started, makes little sense how could nothing create everything and then so there was nothing till 14 billion years ago or so. nothing before the big bang theory, start tearing it a part and theirs more questions then answers.



    Partially addressed above

    The laws of nature as they are currently understood support the Big Bang as the most likely origin of the universe, there are many hypothesis which over time will be tested and rejected or refined, the prior state is far less an issue with the big bang model than say Baryon asymmetry, the particle horizon or the requirement for dark energy which may not exist.


    Quote from pefannext

    for this, there is no proof at all, then again there is nothing saying that its NOT true. i mean this theory at least gives some purpose to life, that we just code who was created by someone/thing.



    Hypothesis.


    A scientific theory requires repeated confirmation by observation and experimentation, they are are testable and make falsifiable, the idea of the universe as a simulation does not fulfill this, it is speculative and has a distinct lack of supporting evidence.

    Yeah, but you said it wasn't amazing for 1080p, which it is. You never mentioned 1440p, which an AMD card would be much better at.

    Yes he did.
    Quote from AlexxRyzhkov»

    First of all, that's a GPU not a CPU. It's a graphics processing unit, aka graphics card.


    Also it depends on what the rest of the specs on your computer are, and wether you have a decent power supply or not.



    But for 1080p gaming, it's a great card. I wouldn't say amazing, but great.

    Presumably they are trying to compete with the Surface Pro without actually understanding why someone would buy the Surface or assuming their target audience is too ignorant to know or care.

    Don't get a Corsair PSU unless you're going with a high end AX or RM unit.


    ಠ_ಠ

    Do we really need to go through all of this again? HX, HXi, RMi, AXi and CX units (avoiding original revision and anything bigger than the 600W) are all serviceable at a minimum (with the HX, HXi, AXi and RMi all being nice high end units) and in the case of the CX units which get far too much crap slung at them, they are about as good (in some ways very slightly better) as the cheap EVGA's people are all too happy to recommend while panning the Corsair.

    Quote from AlexxRyzhkov»

    They're honestly overrated for how much they cost.

    The same can be said of literally any high end PSU, for the vast majority of people once you comfortably meet the ATX spec and have at least Teapo/Samxon level caps there isnt all that much benefit to getting a unit with more expensive Japanese caps (which granted may still have a small edge on lifetime but the better Chinese manufacturers are sourcing the same aluminium and buying the Japanese electrolyte formulas) or a higher end design and you can get all that out of the cheap EVGA and Corsair units just fine.

    Quote from Rotten_Banana»

    what do you mean by the psu???

    is it really that bad??

    Well Logisys make a coupple of passable units but as for the AT650BK, well for starters its not in Ecos's lsit of 80 Plus certified units despite sporting the branding which is an immediate red flag as is the unit being listed as 80 Plus Gold yet sporting 80 Plus badging.

    Well lets try and figure out who the OEM is:

    Being that it has not been tested by Ecos and I can't see a UL or TUV SUD mark on the unit nor can I find certificate numbers for it anywhere I can only assume the unit is not certified by either group which is again somewhat worrying as is the general lack of information, this also means I have absolutely no idea who the OEM is nor what the internals are like.

    At a guess I can assume its being made by the same people as the AT750BKwhich has been certified by Ecos however it still leaves me at a dead end with regards to who the OEM is given that its ID indicated its the first unit of that design to be tested so its either not a rebadge or the unit its derived from has not been certified and it too is lacking any UL or TUV SUD markings.

    So the best I can do is make an educated guess and well, the unit isnt cheap which is somewhat of a positive and from what I can find out both the 5v and 3.3v rails both deliver 24A which is reasonable for a modern unit, so at least its not an old ATX design with a tacked on ATX/EPS12v, so it certainly seems as though the unit is at very least not bottom of the barrel by any stretch. Though it is seriously lacking in cables with 2 molex, of which I would expect 4 or 5, 2 SATA of which I would expect around 10 and a single 8 pin PCIe which for 650w I would generally expect 4 (this also somewhat throws a spanner in the works with regards to its claim of being "SLI/Crossfire ready") this is in itself a bit of a worry, units lacking in connectors like this is generally a solid indicator the unit cannot provide the power which it is rated for.

    So honestly its not looking good, I would definitely recommend replacing it as soon as possible with a higher quality unit.
