    iOS uses services from a company called Skyhook to help with location tracking. they use GPS and wifi access points to pinpoint locations faster than GPS.

    Apple stopped using Skyhook a while back, I think around v3.2 or something. Let me check. Yes, that was when Apple changed (http://techcrunch.com/2010/07/29/apple-location/) to using their own WiFi and cell databases.

    Agreed. Google's darling Android doesn't just track cell towers. They've found it recording wi-fi networks near the user as well and transmitting that data... like every couple of minutes.

    See above. Apple does something very similar. Whenever an app requests a location using GPS, the phone also scans for nearby cell towers and WiFi hotspots. That info is sent up to Apple to build their database.

    Why does Google need to know this?

    Same reason as Apple. While on this topic, let's hit the wayback machine:

    Before the iPhone came out, Google was secretly collecting cell location info via any phone with GPS and Google Maps. Mostly Windows Mobile phones, I would think.

    Good thing, too, because the iPhone debuted without GPS and was pretty much useless in that respect. Then Google unveiled a version of Google Maps using their cell location database, and suddenly the iPhone and other phones without GPS reception were useful after all.

    Yet I use Google every day, but I at least know they're watching me.

    Yet you didn't know Apple was. Ignorance is bliss.

    Except that neither cares about watching YOU. They're watching for cells and hotspots. Sorry, they're more important :)

    Ok, here's the information that's actually known about the consolidated.db file:
    1) It records the locations of nearby wi-fi access points and cell towers.
    2) When location services were originally added to the iPhone, the file had a different name and was stored in a different location. (It was moved as part of the multi-tasking updates.)
    3) The purpose of the file has been explicitly spelled out by Apple *from the beginning*. It is used *by* location services to calculate your current position in order to be able to display your position faster than would be possible solely using GPS. (It's part of the Assisted GPS process.)
    4) There is absolutely no evidence that the file's contents are ever transmitted to anyone. It exists on the iPhone, and in the backup(s) of said iPhone.

    That's almost all correct (*). It's just a receive-only cache to speed up locating and use less battery and network resources.

    (*) WiFi and cell are not part of A-GPS. The A in A-GPS on the iPhone is about receiving satellite information from an assistance server on the 'net.

    Yea the 4x512 does suck, there wasnt even an option to put 2x1 gigers.

    Weird!

    But I figure that I will get a 4 giger kit, slap that in and revel in my 6 gigs.

    A personal best.

    oh , how sad my life has become when the acquisition of ram beyond the past has replaced my once formidable tales of conquest and achievement.

    I make myself sick,:D but why am i smiling?

    Cause its 6 gigs man, that should scream!:p

    I've always thought the tablet PC was cool tech in search of a practical application to take off in popularity.
    Using a tablet as remote for your iTV media center? check
    Using a tablet to wirelessly surf the web/email? check
    Using a tablet as portable music and video player? check

    With the right specs and price, Apple could pull this off.

    Using a tablet to wirelessly open the curtains? check!

    Seriously I'm visualising a home digital interface perhaps replacing the Mac mini in the range. With flash hard drive, rechargeable battery and with a 8" screen. A user might sync it with their main Mac or add a larger display, keyboard and mouse and use it alone.

    Answer the iPod phone with it and iChat whilst sat on the sofa watching iTV and playing with the the iCurtains - brilliant!

    We shouldn't underestimate what progress will be made on voice entry and touch screens - way beyond what we already know!

    Yes, I think this rumor has legs! It's 12" PB meets Mac mini meets past attempts at tablets meets all those who wanted more useable PDA!

    You do realise you can switch your multi-path policy to something like Round-Robin or Least used link or something and use both your fabrics at the same time, giving you double bandwidth (in your 4 Gig port configuration, giving you 8 Gbps, or in a 8 Gbps FC configuration, 16) right ? Actually, you should have a look at what it is set to, some versions of ESX and ESXi are completely retarded and set the default policy to use Fabric 1 only (older versions prior to 4.x didn't have a supported configuration for using both paths at the same time, the support was experimental I believe).

    Or you can run FCoE or FCoIP and use dual 10 Gbps for FC on the cheap (I do realise HBAs can be pricey). Or heck, iSCSI over 10 Gbps links...

    Also, looking at my current I/O statistics for one of our biggest ESXi boxes (about 20 VMs), I see we average about... 10 mbps over the fiber. ;) Servers aren't constantly writing at full bandwidth anyhow and the convenience of centralized SAN management trumps Direct Attached Storage any day of the week in a data center environnement.

    Heck, I wish our DMZ servers could be attached to the SAN (stupid Security policies) so that I could actually grow the filesystems on which the file repository sits... seeing how Sun (now Oracle) wants to charge us over 10k$ for about 72 GBs of disks, just because the hardware is EOL'd and it lacks the 2nd controller so that we can use the drive bays that are free in it...



    If I am not mistaken our PE 2970s are 10gig (x4), I do not know about the Equallogic (I'm just the "helper" on most of this anyway) but I assume it is 10gig as well. What makes this funny to me is that we should be able to use one physical link per server back to the equallogic and have greater throughput versus going from the 2950 to a 3com 4500 (1gig switch, I 10gig switch would be a great start here) and back to the equallogic. (that would throw out redundancy though)(Lead systems guy threw in a 4400 by mistake initally) Most of our VMs are file sharing servers instead of processing servers, I would think the higher the transmit speed the better. We also recently added an R715 and it likes to take the brunt of the load from the cluster (16 physical cores/32GB RAM in it vs 8/32GB in the 2950s) so it having greater throughput would be helpful. We are on 4.1, I will def look into the multipath policy, thanks :)

    one of my favorite phones back in the day were those small nokias which had one of the best menus I have tried. Currently I have the sony T616 which has a decent menu system but not great. I've tried the motorola ones and am not impressed at all which is why I stay away from the SLVR and RAZR. Hopefully the iphone or whatever it will be called will look great, have a great menu system, and play at least 1GB of songs --- thats just my wishlist

    If no new iPhone until 2012, then this further exemplifies Android = WINNING!

    This makes no sense and thus hope it's just another BS rumor.

    I agree. If theres no iPhone in that mean Android wins the smartphone market for the year. Apple would also lose many of the customers to Android whose contracts are up in the summer and they would be locked into 2 year deals with their droids meaning no iPhone in 2012 for them either.

    SI is superior in conversions only
    Imperial is superior as I actually have a feel for the numbers

    Please tell me that's sarcasm. :rolleyes:

    I have a "feel" for Imperial measurements, and they are a pain in the ***.

    I don't think so, and I'm not being sarcastic.

    Temperature is a great example. Celsius and Kelvin are fantastic for science and engineering for obvious reasons, but when it comes to everyday uses, Fahrenheit makes more sense. It's very intuitive to think of numbers on a 100 scale. That's why when you're looking at the weather or taking someone's body temperature, it's easier to get a grasp of what is "high" or "low." Fahrenheit is also more accurate for casual uses because it can express smaller changes more easily than Celsius.

    The metric system also lacks easy naming schemes for everyday sizes. Recipes, for example, would have to be written out in ml rather than cups or spoons. In such a situation, base 10 is not helpful at all because recipes are rarely divided or multiplied by 10. The metric system could in fact be worse for such applications because cutting 473 ml in half is more of a pain than cutting 2 cups in half (and yes, while recipes could theoretically be modified to be in flat metric ratios, the fact is that there are far too many recipes in existence already for that to be realistic in the short-medium term).

    However, we have been seeing the transition to metric in some subtler ways. Soda, water, and juice have been sold in metric quantities for a while now, and I've even seen more and more bags of chips, boxes of cereal, and some candy bars (mind you not popular ones) come in metric sizes. This is obviously advantageous for manufacturers because it means a streamlined production line. I just don't think we're going to get most people to use the metric system for non-scientific daily tasks because it may not be as superior as it would seem at first blush.

    They use a lot more CPU time to process though.

    Again, KDE 2.0, 10 years ago. My Pentium 2 333 mhz didn't break a sweat doing SVG icons then (the Krystal SVG icon theme). ;)

    I seriously doubt this is even an issue.

    You said yourself that wallpapers should be vector graphics. And by that, I presumed you meant the background in the subject of the thread. Safari supports SVG, but imo, it's not really a big thing that there's no support for it as a wallpaper. It's not the first thing people think of when they list Snow Leopard's shortcomings :P

    Sure it's not, but why bother making bigger and bigger pixel images when implementing vector art both has precedent (Gnome, KDE, all the Linux WMs or almost all of them) and is superior for this application.

    For images that can't be easily converted, I'm with you. But I don't understand the resistance to SVG support, which would be a decade late. Sure it's not a shortcoming, but in light of these stories, it would be a "nicer to have".

    I am not sure why the increasing erosion of the middle class and income discrepancy between the haves, and have nots, isn't realized as a major security problem in the US. The working middle class and poor can only be pushed around so much until somebody is going to get pissed off. A socialist/populist revolt ala Egypt is not inconceivable.


    Our financial situation is recognized by some as a great threat. (http://www.disinfo.com/2010/09/the-single-biggest-threat-to-u-s-national-security-is-its-debt/)

    In February the head of U.S. intelligence � Dennis Blair � said that the global financial crisis was the largest threat to America�s national security. All of America�s intelligence agencies apparently agreed.

    The same month, the chairman of the Joint Chiefs of Staff � Admiral Mullen � also agreed.

    Now, Mullen is focusing on a specific economic threat. Specifically, Mullen is focusing on the debt:

    The national debt is the single biggest threat to national security, according to Adm. Mike Mullen, chairman of the Joint Chiefs of Staff. Tax payers will be paying around $600 billion in interest on the national debt by 2012, the chairman told students and local leaders in Detroit.

    �That�s one year�s worth of defense budget,� he said, adding that the Pentagon needs to cut back on spending.

    But at least war is good for the economy, right? At least spending on defense will help the economy recover and climb out of this pit of debt, no?

    Actually, no...

    I just read this whole thread (yeah, big Friday night for me) and I can't believe that there is NOT ONE POST about the repeatedly documented fact that manufacturer rumors from Asustek and Quanta in China are ALWAYS B.S. ! There has never been a decent manufacturer-based rumor in the 4 years I've been an apple rumor reader; the track record of these rumors makes macosrumors.com look reliable by comparison.

    Notwithstanding the flimsy sources, however, I agree that Yonah is dead as a doornail and that apple will move to merom in all notebooks; all the other manufacturers are going to anyway...

    A bit more expensive than you would like, but otherwise seems to fit pretty well.

    Hey, I remember reading about this device back when it was still a prototype. It seems that the company was founded by some ex-Apple engineers (and it certainly shows... that thing suspiciously resembles a shrunken TiBook). I thought, at the time, that using it to run XPee would be such a waste, and after seeing the final product, I'm definitely sure about it.

    If there's one device that could have been developed by Apple, or deserved to run OS X, this is definitely it.

    Just look at the specs:

    1GHz Transmeta Crusoe
    30GB hard drive (shock-mounted)
    512MB DDR RAM
    Dimensions: 4.9" x 3.4" x 0.9"
    Weight: 14 ounces
    800 x 480 W-VGA 5" transflective display (indoor/outdoor readable)
    3D accelerated graphics with 8MB of video RAM
    QWERTY thumb keyboard with mouse buttons and TrackStik
    802.11b wireless
    Bluetooth wireless
    4-pin FireWire (1394)
    USB 2.0
    3.5mm stereo headphone jack
    Microphone
    Speaker
    Digital pen
    Removable lithium polymer battery
    Battery life up to three hours, depending on usage
    OQO docking cable includes:
    3D accelerated 1280 x 1024 VGA video output
    Additional USB
    Additional FireWire (1394)
    Ethernet
    DC power
    Audio out

    These specs roughly match the early 2004 G4 iBook (it has less 1/4 of VRAM but 2x more RAM!), so with some optimization, I'm guessing Tiger/x86 would run fine on that Trasmeta processor. Sure, it's a tad expensive and the battery life isn't that great, but it has some sweet specs...

    Of course, I'm preety sure Apple could do even better, especially with their accumulated experience with the iPod and all those wicked patents, and some Intel partnership and their ULV processors, so I'm very eager to see what they come up with next year... ;)

    Firstly, your perspective would change completely if you ever decide to invest or trade. I don't want hedge funds going for more risk. That is what contributed to the housing bust and mortgage backed securities. I am completely self taught as a trader and investor. In fact, I don't know a single other person who does what I do. And when I do meet someone who works in finance, they are usually just a cog, and I have nothing in common with them.

    Of course people don't "want" risk. But, again, you MISSED THE POINT. Let's try again. People want to take their savings and invest it in the safest investment with the return they desire. If US treasuries beat the stock market, no one would trade stocks If trading in established fortune 500 companies beat out riskier investments, would anyone trade riskier stocks? The answer is probably someone foolish would, but the majority will invest in the safest investment that will provide the rate of return desired. If taxes reduce the rate of return of the safer investments, people naturally begin investing in riskier propositions that have the potential to generate higher rates of return.

    Have you ever represented a company so that it can sell its ownership interests to the public, or have you ever represented the investors in an IPO? Your perspective would change if you ever had. Your assumption that I don't invest is pretty silly considering just about anyone can do it.

    Secondly, and more importantly, I don't think a person should have to give a good reason to be able to do anything. Unless you can prove that a person's actions causes harm to others, why attack it? How is taxing something at the same rate as other income an attack? Oh no, you're treating my capital gains income the same as everyone elses income! I'm under attack! Poor me! The government is no longer going to subsidize my gambling on the success or failure of someone else's established business. Boo hoo.

    Our legal system works that way; the burden of proof is always on the accuser not the accused. Really? That's not true. What about administrative hearings where the burden is on the accused to overcome a prima facie case? (FYI, for a good example of this concept, look at the situation with the proposed rules regarding copyright owners and the presumption that you are pirating if you receive a letter from them accusing you).
