An algorithm could make CPUs a cheap way to train AI
AI is the backbone of technologies such as Alexa and Siri -- digital assistants that rely on deep machine learning to do their thing. But for the makers of these products -- and others that rely on AI -- getting them "trained" is an expensive and often time-consuming process. Now, scientists from Rice University have found a way to train deep neural nets more quickly, and more affordably, through CPUs.
Google wants to be your new bank
It's not just Apple and Facebook diving headlong into the financial world. Google has revealed plans to offer checking accounts in 2020 through a project nicknamed Cache. The search giant won't handle the actual underpinnings -- Citigroup and a credit union at Stanford University will both handle the accounts and feature the most prominent branding. There will still be integration between Google and the accounts, though, and some of it might raise concerns among regulators.
Chrome's new cache will speed up your back button
Bouncing around the internet is set to get a whole lot faster in Chrome, thanks to a new feature called bfcache -- back-forward cache. Google is currently working on a system that will store a web page as you navigate to a new page. If you go back to that page, Chrome will then bring up that page rapidly, without having to build it from scratch. The same applies if you then hit forward.
Ever-changing memory could lead to faster processors
Virtually every central processor in your devices uses a tiered set of memory caches to speed things up by fetching commonly used data. But it's not very efficient -- in trying to accommodate everything, it's rarely the fastest at anything. MIT's CSAIL researchers want to fix that. They've developed a cache system (appropriately named Jenga) that creates new cache structures on the spot to optimize for a specific app. As Jenga knows the physical locations of each memory bank, it can calculate how to store data to reduce the travel time (and thus lag) as much as possible, even if that means changing the hierarchy. Whether an app would benefit from multiple cache levels or one gigantic cache, this system would be ready.
Cuba signs deal with Google to speed up access to its services
A lot has happened since President Obama announced that Google would work with Cuba to speed up its internet. There's a new president in waiting and Fidel Castro has passed away, but the pledge to boost the country's connectivity is moving along thanks to a new agreement between the search giant and Cuba's national telecommunications company ETECSA.
Old console, new tricks: Getting the most out of your Xbox 360
Whether you're holding out for the Kinect-less Xbox One or you've already unpacked a new system, there's still plenty of life left in the Xbox 360. Microsoft will have its new system properly on track after another half dozen or so software updates, but until then, it's all about getting everything we can out of older hardware. Nearly nine years later, here's how to make sure your Xbox 360 is aging gracefully.
Heroic Scenario reward system updated
A couple of weeks back, WoW Insider posted an important public service announcement, warning players of a rather counter-intuitive system whereby only the first scenario of the day would award a loot cache, regardless of whether that scenario was normal or heroic. We warned players to avoid them being locked out of a chance at 516 loot, and the palpable frustration that came with it. Now, though, Blizzard Community Manager Taepsilum has posted about a very recent change. It should be noted that this is not in the most recent batch of hotfixes, and that Taepsilum is an EU Community Manager, posting the day after EU servers restart. Therefore, it is possible that this change is currently only live in the EU. Proceed with caution. Taepsilum Quote: Remember that you only get the Heroic Cache of Treasures from the first scenario you do in a day (and only if it's a HC scenario. so if you do a normal scenario first you won't get one at all). The rest of the time you just get Greater Cache of Treasures. This has actually been changed today and the hotfix should already be live. You should be able to get both of these rewards now, as long as you complete one heroic and at least one normal scenario once per day. You shouldn't have to worry about doing a heroic scenario before you do a normal one, the order doesn't matter anymore. source This is a great change to what was a rather counter-intuitive system, but please do be very careful about trying it, especially on US servers. I have tested it on EU servers and can confirm that it does work, I did a normal scenario first, followed by a heroic one, and received the Greater Cache, then the Heroic Cache.
Toshiba goes perpendicular to solve MRAM's power issues, rethink cache memory
As much of a breakthrough as magnetoresistive RAM might be for its ability to retain data while powered off, its susceptibility to leak currents while turned on has made it impractical as a replacement for cache-oriented memory like SRAM. Toshiba's new approach could almost literally turn the situation on its head. By magnetizing spin torque MRAM (ST-MRAM) in a direction perpendicular to the magnetic layer, Toshiba cuts off the avenues for leaks without sacrificing speed. The switch away from in-plane magnetization is an upside for the memory as a whole -- it shrinks normally large elements to below 30 nanometers and cuts the overall power draw of MRAM by about 90 percent. While there's no timetable for when we'll see such cache in a shipping product, Toshiba expects it to reach mobile processors, where even slight power savings can make a big difference. If our next smartphone or tablet survives that much longer on battery through memory we can't even see, we'll know who to thank.
SanDisk announces 32GB ReadyCache for Windows: $55 at Amazon, keep your existing HDD
SanDisk has built itself a decent reputation in the SSD game, and a cheap cache-only drive is a logical addition to its line. Unlike regular SSD or hybrid upgrades, you don't have to transfer your system to the new drive -- the 2.5-inch, 32GB add-on simply hooks up to a spare SATA III port alongside your spinning storage and then you run SanDisk's ExpressCache software to do the rest. The program, which is currently Windows 7-only, monitors which files you access most frequently and then automatically caches them on the SSD, promising up to 12x faster application launches and also faster boot times compared to your HDD working on its lonesome. Importantly, the ReadyCache works with multiple hard drives too, rather than just boosting your primary drive -- a feature that SanDisk claims gives it a one-up over most other caching solutions. The list price is $100 but Amazon has it up right now for $55.
BBC iPlayer for iOS update coming with downloads and offline viewing, on Android soon
The BBC has revealed that an update arriving Tuesday for its iPlayer app on iPhone and iPad will add the ability to download shows for viewing offline, instead of being streaming only. First reported by The Guardian, it will let those with paid up TV licenses load their phones and tablets with plenty of programming to view when and where (including abroad) they want, for up to 30 days or within 7 days of being watched. Those restriction will keep viewers from building up libraries they can truly keep with them indefinitely, and it should be noted that the app will only let users download shows over WiFi for now, not surprising when we remember how long it took to add 3G streaming. Also interesting is the Beeb's decision not to charge extra for downloads, but we'll have to wait and see if competitors like ITV follow suit. The app is not live in iTunes yet, but we'll keep an eye out and let our UK based friends know when it's available to download. That here in the US we're (still) waiting for global iPlayer access hasn't made us jealous at all. Update: Version 2.0.0 is out, check the gallery for screenshots or the BBC's blog post for a few more details and stats on how people are using iPlayer.%Gallery-164250%
Google updates PageSpeed Service so you don't waste precious seconds waiting for pages to load
Last year, Google launched its PageSpeed Service, aiming to improve our experience across the web while reportedly deferring its own financial interests. The concept was sound -- similar services like Akamai work to accelerate web browsing by caching pages in much the same way -- but there's always room for improvement. The latest PageSpeed beta uses some straightforward techniques to improve performance even further, using a new rewriter called "Cache and Prioritize Visible Content." Using this new tool, your browser will load content that appears "above the fold" before fetching text and photos that would be initially hidden on the page, while also prioritizing other content ahead of Javascript, which often isn't needed as quickly as more basic elements. Finally, for pages that contain HTML that isn't cacheable, such as when personalized info is returned, standard portions of the site are cached and displayed immediately, while other content loads normally. The new tool isn't a perfect fit for every webpage, but we'll take a boost wherever we can get it.
The Game Archaeologist: Richard Garriott's haunted cache
Whenever you get really into a new hobby, it's natural to want to blab about it to anyone who drifts into your gravitational field. That's why we all talk about MMOs, right? It's also why any friends, family members, and coworkers have had to put up with excited rambling about my discovered love for Geocaching. Some of you probably know Geocaching, as it's been around for over a decade now. For those of you who haven't, it's a worldwide treasure hunt that involves over a million and a half "caches" of various sizes that are hidden and then marked with GPS coordinates. Players head to the official site or one of the open-source projects to get the coordinates and go hunting for them. There's a useful two-minute introduction to this hobby on YouTube if you're curious. I noted on our Massively Speaking podcast that Geocaching has a lot in common with MMOs: Both encourage questing and exploration, both have treasure to be found, and both plug you into a community of adventurers. Listener Terrence heard this and send in an email with an interesting revelation that ties these two hobbies even closer together, as a game developer brought his online world to a real-world location. Ladies and gentlemen, may I present to you Richard Garriott's haunted cache.
Intel 313 SSDs bring improved caching to ultrabooks, desktops, life in general
Just like Intel's older 311 batch of small cache SSDs, the new 313 series is designed to sit alongside a traditional spinning HDD in order provide a tasty blend of speed and capacity. These newer drives are still SATA II, so there's no 6Gbps action here, but they use superior 25nm SLC flash, offer faster speeds for the same price (starting at $120 for 20GB) and are explicitly approved for use in the coming wave of Ultrabooks -- so don't be surprised if that's where you meet 'em next.
Crucial outs Adrenalin Solid State Cache Solution, less long-winded m4 SSDs
Until the cost of flash storage comes down to the same plane of existence as most human wallets, hybrid solutions -- which pair an HDD with an SSD cache -- remain a smart way forward. OCZ scored some attention with its Synapse products, so now Crucial has to wave its arms in our faces and point to its own offering: the Adrenalin Solid State Cache Solution, which pairs a 50GB m4 SSD with proprietary caching software, and which will be out sometime this quarter for an undisclosed but surely rivalrous price. In the meantime, a fresh range of pure-breed m4 drives is already available, looking much like their predecessors but now whittled down to a mere 7mm in thickness so they can be squeezed into ever-narrower crevices. Pricing starts at $119 for 64GB and tops out at $795 for 512GB -- like we said, not your average plane of existence.
Friday Favorite: Lazarus Extension for Safari saves your form text
Don't you hate that sinking feeling you get when you spend five to ten minutes filling out a form -- and then you lose all the data because of a hiccup in your Internet connection, or because of Safari's tab reloading quirks? Before that happens to you again, you should check out Lazarus. It's an extension for Safari, Chrome and Firefox that stores your form data in case you lose it. It works with almost all web forms, with web-based email clients and even in some content management systems like WordPress. The extension/plug-in stores your text in a database and lets you restore it with a single click. Each field that is supported by the extension will display the Lazarus ankh symbol. If you lose your data, you can click on the symbol to restore the cached text. The Safari extension has a few options that'll let you encrypt form data, exclude sites from working with Lazarus, and change the number of days the form data is stored. Lazarus is lightweight and doesn't affect browser performance. It's a life-saver for WordPress bloggers and anyone who fills in a lot of online forms. Lazarus is available for free from Interclue's website.
Nokia Maps officially arrives on iOS and Android, touts offline storage
Nokia Maps is still getting development love, despite the Finnish manufacturer pinning its smartphone hopes and dreams on Windows Phone. The HTML5-powered maps are now willing to play ball with iOS and Android devices. Previously one of Nokia's strongest built-in functions on its own phones, the maps perform well on rival hardware -- although pinch-to-zoom isn't working on our Google devices. With Microsoft's Windows Phones touting some impressive HTML5 credentials, it wouldn't shock us to see something very similar running on Nokia's incoming WinPho. There's a smattering of online settings, including transport directions, but the best part is a new offline mode that will download neighborhood maps from your WiFi connection. Navigate your phone browser to the source link below to see how it works.
Amazon Silk browser spins a faster mobile web, courtesy of cloud servers (video)
Part of Amazon's new Kindle Fire pitch is its promise of Amazon Silk -- a "split browser" exclusive to the tablet that gets the heavy lifting done on its EC2 cloud servers and promises faster access as a result. Dubbed Silk to represent an "invisible, yet incredibly strong connection", it takes advantage of Amazon's existing speedy connections, and that so many sites are already hosted on its servers to speed up web access. Another feature is its ability to learn from previous web surfers and use their data to determine how to render a page, and which sites to precache on the device before you even select the next link. While mobile browsers like Skyfire and Opera have offered speed boosting proxies before, Amazon thinks its AWS prowess and the addition of "dynamic decisions" about what to render locally or in the cloud takes it to another level. Read our live blog of the event for more details, or check out the video explanation and press release after the break.
OCZ debuts Synapse Cache Series SSDs to compensate for your HDD's shortcomings
This really shouldn't come as much of a surprise, given some of OCZ's other offerings, but the company has outed its Synapse Cache SSDs so you don't have to suffer the speed limitations inherent in spinning disk storage. These 2.5-inch, 6 GB/s SATA drives come in 64 and 128GB flavors, and do the dual drive dance with your HDD of choice using the firms' Dataplex caching software. That nifty bit of code hastens data retrieval by dynamically managing your data, placing frequently used info on the speedy SSD, and shoving the rest on your capacious, cheap-as-chips HDD. When can you up your storage speed limit and how much will it cost? OCZ's not telling, but the drive's full performance specs can be found in the PR and source below.
TUAW's Daily Mac App: Onyx
Cleaning up a Mac is something many users never do, but if you want to squeeze all the performance and disk space you can out of your Mac, you need a tool like Onyx. A free multi-purpose utility, Onyx lets you run a myriad of system tasks such as disk maintenance, cache clean-up and index rebuilding. You can use Onyx to clear away the cobwebs that collect in things like the browser cache, font caches, boot, kernel and extension caches, as well as logs from crash reporters, system diagnostics and Software Update. If that wasn't enough, you can also get Onyx to delete previous iTunes libraries, the QuickTime Content Guide, recent items lists and even Mail downloads. OK, you can do most of these things yourself manually, but Onyx makes it fast and easy to do it all from one place. Cleaning isn't the only talent Onyx has -- it's able to do quite a few maintenance and repair tasks such as verifying your startup disk, which it will do on it's first run automatically. By rebuilding the Spotlight Index or LaunchServices, you can often cure small corruption issues with your Mac. You can check the S.M.A.R.T. status of your internal disks, verify file structure and fix disk permissions without having to open Disk Utility. Onyx will also let you change some hidden preferences in Finder and other Apple programs such as iTunes and Mail, allowing you to tweak a few things here and there. Onyx is a great free system utility that we've covered many times in the past and which allows you to perform a load of different tasks all from one application. If you're interested in cleaning out OS X, download Onyx today. By the way, Onyx also works well with OS X Lion.
OpenPaths lets you visualize your iPhone location data, donate it to science (video)
What use could science possibly have for your iPhone location data? Well, you won't be curing cancer, but you could theoretically be contributing to epidemiology, land use surveys, or a study proving that people move around just as quickly on foot in New York as they do inching down the 405 in LA. At least that's the idea behind OpenPaths, a web-based tool that lets you securely and anonymously "donate" your cache. If you've upgraded to iOS 4.3.3, your iPhone will no longer store your location, but there should be plenty of coordinates spinning around on your hard drive to play with. After downloading the OpenPaths Uploader, you'll be able to visualize your own location information, and even if you've somehow deleted the data from your computer, the tool will search Time Machine backups (for Mac users) -- a little scary, no? Of course, there's always potential for misuse with any such service, but a researcher probably won't care that those late nights at the office were actually spent in Cindy's home office, unless that researcher also happens to be your wife.
