We all know that to stay hydrated, we should be drinking at least 8 glasses of water a day. The only thing is though, that water is… well… boring. My beverage of choice used to be Diet Coke, but I was able to wean myself off of it by switching over to ice tea. I [...]
Report: Lovefilm will cease UK game rentals by August 8th
Lovefilm has told Eurogamer that it will no longer offer game rentals by mail in the UK after August 8th. Additionally, the Amazon division confirmed via its blog that the option is no longer available to new subscribers. In addition, existing customers will no longer be able to add the service, a fact that only came to light when someone spotted it on a company FAQ (see the More Coverage link). Lovefilm apologized profusely for the non-communication, and explained that the change was made so it could focus on streaming content instead. It promised to contact subscribers "in the very near future" to confirm the policy, and "strive to communicate directly with our customers" rather than letting them find out through the media. The firm's yet to actually confirm that the service will be cut off completely next month, however -- perhaps that would be a good place to start.

Apple Q3 2013 earnings call to take place July 23, 5PM ET
Apple's next earnings call will be held on Tuesday July 23, at 5PM ET/2PM PT following the Q3 2013 earnings release that day. Typically on these types of calls, we'll be treated to a series of prepared statements by CEO Tim Cook and CFO Peter Oppenheimer, and it's always good to hear Tim Cook speak. Oh, and there'll likely be the standard question and answer session at the end.
The good news is that the call will be streamed live on the web, and anyone with an iOS device on 4.2 and up, a Mac on OS X 10.5 and above or a PC running QuickTime 7 can listen along as it happens. iMore will of course be bringing you full coverage as it all goes down. Any predictions?

New hardware design protects data in the cloud
July 2, 2013 ? Cloud computing -- outsourcing computational tasks over the Internet -- could give home-computer users unprecedented processing power and let small companies launch sophisticated Web services without building massive server farms.
But it also raises privacy concerns. A bank of cloud servers could be running applications for 1,000 customers at once; unbeknownst to the hosting service, one of those applications might have no purpose other than spying on the other 999.
Encryption could make cloud servers more secure. Only when the data is actually being processed would it be decrypted; the results of any computations would be re-encrypted before they're sent off-chip.
In the last 10 years or so, however, it's become clear that even when a computer is handling encrypted data, its memory-access patterns -- the frequency with which it stores and accesses data at different memory addresses -- can betray a shocking amount of private information.
At the International Symposium on Computer Architecture in June, MIT researchers described a new type of secure hardware component, dubbed Ascend, that would disguise a server's memory-access patterns, making it impossible for an attacker to infer anything about the data being stored. Ascend also thwarts another type of attack, known as a timing attack, which attempts to infer information from the amount of time that computations take.
Computational trade-off
Similar designs have been proposed in the past, but they've generally traded too much computational overhead for security. "This is the first time that any hardware design has been proposed -- it hasn't been built yet -- that would give you this level of security while only having about a factor of three or four overhead in performance," says Srini Devadas, the Edwin Sibley Webster Professor of Electrical Engineering and Computer Science, whose group developed the new system. "People would have thought it would be a factor of 100."
The "trivial way" of obscuring memory-access patterns, Devadas explains, would be to request data from every address in the memory -- whether a memory chip or a hard drive -- and throw out everything except the data stored at the one address of interest. But that would be much too time-consuming to be practical.
What Devadas and his collaborators -- graduate students Ling Ren, Xiangyao Yu and Christopher Fletcher, and research scientist Marten van Dijk -- do instead is to arrange memory addresses in a data structure known as a "tree." A family tree is a familiar example of a tree, in which each "node" (in this example, a person's name) is attached to only one node above it (the node representing the person's parents) but may connect to several nodes below it (the person's children).
With Ascend, addresses are assigned to nodes randomly. Every node lies along some "path," or route through the tree, that starts at the top and passes from node to node, without backtracking, until arriving at a node with no further connections. When the processor requires data from a particular address, it sends requests to all the addresses in a path that includes the one it's really after.
To prevent an attacker from inferring anything from sequences of memory access, every time Ascend accesses a particular memory address, it randomly swaps that address with one stored somewhere else in the tree. As a consequence, accessing a single address multiple times will very rarely require traversing the same path.
Less computation to disguise an address
By confining its dummy requests to a single path, rather than sending them to every address in memory, Ascend exponentially reduces the amount of computation required to disguise an address. In a separate paper, which is as-yet unpublished but has been posted online, the researchers prove that querying paths provides just as much security as querying every address in memory would.
Ascend also protects against timing attacks. Suppose that the computation being outsourced to the cloud is the mammoth task of comparing a surveillance photo of a criminal suspect to random photos on the Web. The surveillance photo itself would be encrypted, and thus secure from prying eyes. But spyware in the cloud could still deduce what public photos it was being compared to. And the time the comparisons take could indicate something about the source photos: Photos of obviously different people could be easy to rule out, but photos of very similar people might take longer to distinguish.
So Ascend's memory-access scheme has one final wrinkle: It sends requests to memory at regular intervals -- even when the processor is busy and requires no new data. That way, attackers can't tell how long any given computation is taking.

Heat wave tests California power grid. Why no blackouts so far?
A heat wave scorching its way through the West is the first major test of summer's spiking energy demand, but it seems to be passing the test. Better technology and communications may be to thank for that. But utilities are still on high alert, particularly in California where two nuclear plants have gone offline. ?
Maria Wieser, of Italy, takes a drink of water while sightseeing in Death Vally National Park Friday in Badwater, Calif. Utilities recommend turning off unnecessary lights, postponing major appliance use until after 6 p.m., and turning air conditioners up to 78 degrees, or using a fan instead.

It's the grid's first major test of summer's spiking energy demand, and so far it seems to be passing. Improved grid technology and better communication of energy use have helped prevent any major blackouts so far. But the permanent closing of one major nuclear plant last month and the temporary shutdown of another last week further complicates the stress of summer's high temperatures, and utilities remain on high alert.
"Over time they?ve added transmisson to the grid," Jeff Roark, senior project manager at Electric Power Research Institute, said in a telephone interview, "as well as technology that provides info on what?s happening on the grid. Those devices are providing new information of the type that utilities didn?t have before."?
The improved information technology is helping customers as well. Utilities can now provide realtime demand information to consumers online and send out alerts via mobile phones and social media. That helps spread the call for efficiency during times of peak demand.?
Social Networking: How to get started on your iPhone and iPad!
Everything you need to know about choosing the right social network(s), signing up, and getting the best apps for you and your iPhone or iPad!
Today on Talk Mobile we asked if and how you needed to be on social networks. While it might seem everyone is already hip deep in online status and sharing, the truth is, if you're just getting started online or on mobile, social can be more than a little confusing if not downright intimidating.
If you're already a social expert, bookmark this article so you can share it with your friends and family who aren't yet as socially savvy, and jump down to the comments so you can add your experience and advice. If you're all new to networking, keep on reading and we'll help get you started!
Facebook is for those who want to connect to friends and family
Facebook is the social network. It's the biggest online community in the world, and almost entirely friend-focused. If you have a lot of friends and family already using Facebook, if you want to find the people you went to school with, if you want to share events and photos and videos with the people most important to you, and if you want to stay in touch with relatives and acquaintances around the world, Facebook might be for you.
On the downside, Facebook has been pretty bad when it comes to privacy, so make sure you take time to double and triple check your settings so that once you're signed up, you're absolutely sure you're only sharing with the people you want to be sharing with.
Twitter is for following celebrities, and trying to build followings
Twitter is a micro-blog, or a way to share what you're doing in real-time. Think of it as public SMS. You can post general messages that everyone and anyone can see, or you can target them at specific other users by including an @ symbol and their Twitter name in the message. Because of Twitter's more public nature, you can find some of your favorite celebrities, including actors, singers, sports stars, writers, and more. You can also participate in larger discussions via "trending terms" using # hashtags. It's also great for keeping up with your peers. Think of it like a giant, virtual water-cooler.
Because of Twitter's more public nature, it can be harder to amass a group of followers large enough to receive the same kind of engagement and attention you give out to those you follow. That means it can take a lot more work to build up a Twitter network.
App.net
ADN is for nerds with $36 and a shared dream.
App.net (ADN) is platform that, among other things, offers a Twitter-like micro-blogging service. It also offers file storage and robust instant messaging. Full accounts cost $36 a year, while free, limited accounts currently require an invitation. Because of that, it's attracted a lot of nerd engagement, and engendered a lot of nerd dedication. The people behind it also promise to keep their interests aligned with ours, their users'.
If you're not up for a paid service, or a limited service, or a bunch of nerd conversation, however, you're probably better off with one of the other networks.
There's no official App.net social client, but there is a Passport app to help you choose from the many third party ADN apps.
Google+
Google+ is for people who are all-in on Google and Android
Google+ is Google's answer to Facebook. It doesn't quite have all the features, or all the members yet, but it does a lot of stuff really well. It's also integrated into almost everything Google, from Gmail to Android to YouTube and everything in between. In terms of style, it's a mix of Twitter and Facebook, where you can follow (circle) people who don't have to follow you, but you can also write as much as you want, and create albums and events, and even have video conference calls called Hangouts.
On the other hand, Google's being borderline obnoxious in their way they're forcing Google+ on people, and even with all their effort it's mostly hardcore Google and Android users who make up most of their active community.
Instagram is for those who love taking and looking and photos
Instagram, now owned by Facebook, is a micro-blogging service geared towards photography (and now video as well). That means, food, fashion, pets, and whatever else interests you and those you follow. Much like Twitter, you can post short messages and include other people in them with an @ sign before their account name. The difference is that everything on Instagram is geared towards taking and sharing moments. Unlike Twitter, however, there's no chatter to scroll through between the pictures. It's all images and video, all the time.
Of course, if you're not into taking, sharing, and commenting on photos (and now videos as well), you probably won't enjoy Instagram.

Pinterest is for those who want to share and explore collections
Pinterest is all about collecting and sharing the things that you love. Whether that's fashion or furnishings, kitchenware or footwear, art or heirloom vegetables. Anything that interests, you can pin for others, or find pinned by others. A pin can start with a photo or a video that you either find on the web, or upload yourself. Others can follow or repin your pins, if you allow it, and you can follow or repin theirs.
If you're not into collecting things, or browsing the collections of others, however, Pinterest probably won't appeal to you.
LinkedIn is for finding and making business connections so you can leverage all the synergies!
LinkedIn is classic business networking using modern social technologies. You fill in your profile with your positions and experience, past and present, and you connect to the people you already know. Then you start connecting to the people they know, and the people you meet, and you ask for connections to the people you want to meet. If you're tactically minded, you can find new business options and opportunities, and if you're socially minded, you can share inspiration and insights.
If you're not into wheeling and dealing, and if you don't care about who you know more than what you know, you might find LinkedIn more stressful than it's worth.
Path
Path is the social network for people who only want to be a little bit social
Path lets you do pretty much what other social networks do -- make connections, share status, and share pictures, but instead of allowing virtually limitless connections, Path keeps them relatively small. It's really meant for only very close friends and family members, and very specific groups of people. You can also push out any and all of your Path updates to other popular social networks you might use, like Facebook, Twitter, etc.
On the downside, it's one more social network to manage that really doesn't provide any benefit to simply restraining and constraining yourself on Facebook.
Foursquare
Foursquare is for those who just want to keep track of where they've been
Foursquare is what's referred to as a location-based social network. Other social networks can do location, of course, but Foursquare focuses on it completely. You arrive somewhere, open Foursquare, "check in" to the location, share comments and photos, and see who else is either there at the same time, or has left photos or comments in the past.
Because other social networks also do location, unless you specifically want to only do location, you might want to save yourself the trouble of maintaining a separate Foursquare account for just that.
Tumblr
Tumblr is for people who want to easily share or re-share things in a blog-like format
Tumblr lets you quickly and easily text, photos, links, audio, video and more in a format very similar to a blog. Like any social network, you can follow and like what's on Tumblr, but in this case you're following blogs and their content as much as you're following a person. The distinction might be subtle, and the format blurs the line between traditional blog and a micro-blog like Twitter. And that's kind of the point. If you're just looking for an easy way to share stuff online, the multi-purpose nature of Tumblr can be a definite plus.
Conversely, because Tumblr is so well optimized for doing just exactly what it does, there's very little traditional social functionality built in beyond that.
Flipboard is for those who want to read Facebook and Twitter rather than interact with them
Flipboard shows how you don't actually have to be social to benefit from social networking. With Flipboard, you can link your Twitter and Facebook accounts, along with other sources, and simply enjoy them as a more passive, more relaxing reading medium. That way you still get to see everything shared by your friends and the people you follow -- including politicians, celebrities, academics, and more -- but you don't have to deal with the comments and discussion that come with actually being involved on the networks themselves.
Of course, you miss out on the community and connection building aspects of social networks this way, but for some that's still more blessing than curse.
And more!
Beyond all the social networks and apps listed above, you can find many more still. Some are for popular niches, like Untappd for beer or Elixr for cocktails or Foodspotting for food. Others take the communications aspect to the extreme, like Whatsapp, Glassboard, or Hipchat. And the list goes on and on. Once you've gotten comfortable with mobile and social, you can find all sorts of social networks, and groups within social networks, to match your particular interests.
Which social networks are your favorite, and which apps do you use most to be social on iOS? Let me know!
