Submission Ask Slashdot: Is the gap between data access speeds widening or narrowing?

DidgetMaster writes: Everyone knows that CPU registers are much faster than level1, level2, and level3 caches. Likewise, those caches are much faster than RAM; and RAM in turn is much faster than disk (even SSD). But the past 30 years have seen tremendous improvements in data access speeds at all these levels. RAM today is much, much faster than RAM 10, 20, or 30 years ago. Disk accesses are also tremendously faster than previously as steady improvements in hard drive technology and the even more impressive gains in flash memory have occurred. Is the "gap" between the fastest RAM and the fastest disks bigger or smaller now than the gap was 10 or 20 years ago? Are the gaps between all the various levels getting bigger or smaller? Anyone know of a definitive source that tracks these gaps over time?

Unbelievable. From TFR:

So do Ethernet cables have their own sound? This is no longer a question but a statement. The cable between switches is less important than the ones connected to the end points (NAS and/or streaming device), but a decent type like the AudioQuest Carbon is certainly worth the price in high end systems.

Apple Pay For the UK 75

An anonymous reader writes about when Apple Pay will be available in the UK. "A major UK bank's concern over data collected by Apple Pay is reportedly stalling negotiations to launch the mobile payments service in the country by 'the first half of 2015.' The Telegraph reports that 'at least one' of the UK's biggest banks is 'uncomfortable with the amount of personal and financial information Apple wants to collect about its customers.' Apple has been adamant about its approach to collecting users' data via Apple Pay. 'We are not in the business of collecting your data,' said Apple exec Eddy Cue when introducing the service in September. 'So when you go to a physical business and use Apple Pay, Apple doesn't know what you bought, where you bought it, or how much you paid for it. The transaction is between you, the merchant, and your bank.'"

Researchers Claim Facebook Is 'Dead and Buried' To Many Young Users 457

JoeyRox writes "The recent decline in Facebook's popularity with teenagers appears to be worsening. A Global Social Media Impact study of 16 to 18 year olds found that many considered the site 'uncool' and keep their profiles alive only to keep in touch with older relatives, for whom the site remains popular. Researches say teens have switched to using WhatsApp, Snapchat, and Twitter in place of Facebook."
