    Opera's mobile browsers are quite popular because of their ability to compress data, but it's unfortunately been limited to just that -- the browser itself. This becomes less and less useful as smartphones continue to evolve, since our data usage patterns encompass so much more than just the simple browser: many of us are constantly streaming music, uploading and downloading images and apps, and so on. To lighten the hefty load we inflict on our monthly data allotments, Opera has launched a beta of its new Android app called Opera Max, which compresses most of the information that goes through your device -- websites, images, videos and many of your usual apps (Instagram and Vine immediately come to mind, but the possibilities are wide open). Opera makes this happen by setting up a Virtual Private Network (VPN) that measures all of the data coming through your device. Data requests are then sent through Opera's servers, though the company tells us that it only measures how much data you use and how much you save -- in other words, it says your information is safe. There's no guarantee on how much data you'll save, but if you're a gulper like us, we suspect it'll be a significant amount. While the company hasn't specified how many beta testers are allowed, it does say that room is limited; if you're into the idea, you'll need to join its Google Plus Community, opt in to the beta and then download the app from the Play Store.

    For more than three years, Onavo has plied its trade reducing internet costs for smartphone users. Facebook knows that data-shrinking is key to its founder's plan to connect the world, which is why it's bought the Israeli startup. Under Facebook's guidance, Onavo will work with members of the Internet.org coalition to increase the efficiency and lower the cost of web access. If you're an Onavo user and are worried that its apps are about to disappear, worry not, for the company will continue to operate under its own brand. Expect Facebook's apps to get a speed boost in the future, helping it deliver its growing influx of ads.

  • Apple reportedly buys mobile data compression startup AlgoTrim (confirmed)

    Data compression isn't the sexiest of subjects, but after Facebook pledged to slim down its digital footprint, it's suddenly hot news. You might be interested to know, then, that Apple has reportedly snapped up Swedish startup AlgoTrim, which specializes in lossless compression algorithms. TechCrunch believes that AlgoTrim's know-how will slim down iOS device data usage -- as the outfit's JPEG files are apparently six times smaller than the average. CultOfMac, however, believes that the deal may hint at a move towards computational photography -- hinting that we may see Apple's version of Nokia's pixel oversampling tech pop up in future devices. While the thought of a PureView iPhone would set plenty of hearts aflutter, there's probably more chance that Elon Musk will build you your own private Hyperloop. Update: Yup, an Apple spokesperson has confirmed the deal to AllThingsD.

  • Chrome for Android build may tout a proxy-based speed boost

    A fast smartphone will only go so far toward improving browser load times if the connection isn't there to back it up. If a discovery within a recent build of Chrome for Android is any hint, Google may have its own solution to that bottleneck. New code flags reference Google-run proxy servers that would squeeze pages using SPDY, improving performance at least slightly for the bandwidth-deprived. While there's not much more to go on, the finding is enough to suggest that roughly equivalent boosters like Amazon Silk and Opera Turbo could have a real fight on their hands. We'd advise caution when the flags are only accessible by running an ADB command -- they're clearly not ready for prime time. Should Google flick the switch on compression for Chrome's main release track, though, Android users may not need a third-party browser to sip the web through a thin straw.

  • Google's Zopfli compression algorithm aims to speed up the web

    Google's latest attempt to squeeze data into increasingly smaller and smaller spaces comes with a rather silly sounding name inspired by Swiss bread. Zopfli is a compression algorithm that Mountain View claims can create files between three and eight percent smaller than Zlib. Of course, the trade off is that it requires between two and three times as much CPU time to finish shoving everything into a neat little package. Obviously this isn't an ideal solution for on-the-fly compression. However, decompression speeds are unchanged and don't require a special library to unpack. The most obvious use of the technology will be in the mobile space where static website elements an be compressed once and transferred frequently. That would mean quicker load times, less battery drain and, perhaps most importantly in this era of capped data plans, less bandwidth usage. For a few more details check out the source link.

  • Send full-res iPhone photos and spare your bandwidth via Beamr

    The iPhone 4S, iPhone 5 and the fourth-gen iPad all carry one key component: a really awesome camera. The 4S has proven to be a workhorse capable of producing some startlingly good images, and the combination of iOS 6's Panorama feature with the improved optics of the iPhone 5 is letting us fall in love with iPhone photography all over again. There's a drawback, though, when it comes to sending those lovely megapixels to friends via email, Facebook or Twitter: they're getting compressed, a lot. Resolution and quality take a hit, and while you can use local sync or Photo Stream to get the full-resolution images, that adds time and complexity. Now a new free app called Beamr is providing a way to get those full-res images off your phone in style -- and without blowing out your network connection. Using Beamr is as simple as launching the app and selecting multiple photos from your library. These go into a "glossy magazine" layout, with an option for you to customize your cover image, headline and credit. Select a sharing mode (email, Facebook or Twitter) and that's all there is to it. The result is a microsite of your images, in the same magazine format, hosted on the Beamr website. Your friends will see the full 8-megapixel resolution of your iPhone photos, in top quality; the images, however, will use only a fraction of the storage space and bandwidth of conventional JPEGs without sacrificing visual quality. Especially on pre-LTE cell networks, the difference in upload time is quite noticeable -- a four-image Beamr magazine makes it off the phone in about the time it would take to send one or two images conventionally. Beamr's Israeli developer, ICVT, first gained notice for its JPEGmini product. Implemented as a web service, a standalone server module and as a Mac app, the proprietary process analyzes a digital image to determine how much it can be compressed without sacrificing perceptible detail. Once that level of compression is fixed, the software automatically puts the photo through a custom JPEG encoder that squeezes the image to the max. The biggest advantage of this approach: the resulting files are plain ol' JPEG format, rather than an esoteric filetype requiring a special browser plugin or preview app. That means you can use them anywhere a normal JPEG would fit -- on your website, for example -- and not worry about compatibility issues. The file size savings can be substantial, ranging from 40 percent up to 80 percent depending on the size and composition of the original. You can try out the JPEGmini tools using the free Lite version of the Mac app, or via the web form. As for the Beamr app, it's fun and dead simple; there are, however, a few minor drawbacks. You can't delete a Beamr magazine right now, so best to be 100 percent sure that you don't include any questionable images. Further layout and customization options may be in the works for in-app purchasing, but right now there's only the one layout choice. You might wish for the ability to simply send your Beamr-compressed image to your regular photo sharing service without the magazine wrapper. In any event, the app is a promising start and a nice showcase for the JPEGmini compression suite. Give it a look.

  • Microsoft unveils Data Sense for Windows Phone 8, to debut on Verizon devices

    Microsoft has just outed Data Sense, a new app for Windows Phone 8 that helps ensure you don't burn through your data plan. On top of tracking your usage app-by-app, it compresses every single web page you browse to keep data consumed to a minimum, and also sniffs out WiFi hotspots when they become available. The app features a Live Tile to give an ongoing saga of the megabytes you've consumed and will warn you near a preset limit. Redmond claims the hotspot sniffing and compression will let you consume 45 percent less data "when compared to the competition" -- likely a reference to iOS and Android, which already have a similar feature. Data Sense will arrive first on Verizon this fall, but there's no word yet on when other carriers will have it. To check the PR, go past the fold.

  • OpenGL ES 3.0 and OpenGL 4.3 squeeze textures to the limit, bring OpenVL along for the ride

    Mobile graphics are clearly setting the agenda at SIGGRAPH this year -- ARM's Mali T600-series parts have just been chased up by a new Khronos Group standard that will likely keep those future video cores well-fed. OpenGL ES 3.0 represents a big leap in textures, introducing "guaranteed support" for more advanced texture effects as well as a new version of ASTC compression that further shrinks texture footprints without a conspicuous visual hit. OpenVL is also coming to give augmented reality apps their own standard. Don't worry, desktop users still get some love through OpenGL 4.3: it adds the new ASTC tricks, new visual effects (think blur) and support for compute shaders without always needing to use OpenCL. All of the new standards promise a bright future in graphics for those living outside of Microsoft's Direct3D universe, although we'd advise being patient: there won't be a full Open GL ES 3.0 testing suite for as long as six months, and any next-generation phones or tablets will still need the graphics hardware to match.

    Elgato is releasing the Game Capture HD, a device that lets game-casters and YouTube walkthrough mavens shed low-resolution, over-the-shoulder smartphone footage once and for all. The sleek black box sits between console and display, enabling gamers to record their speed runs and kill records for the world to see. Xbox 360 users can daisy-chain the gear into their HDMI set-up, while PS3 users will have to use the bundled AV cable to circumvent Sony's stronger copy protection. The footage will then be compressed with the company's H.264 know-how and pushed to your PC or Mac for uploading. When it arrives at the start of June, it'll set you back $200 -- just giving you enough time to get practicing your soothing and confident narration voice.

  • Onavo Extend stretches your data plan, now with CDMA/LTE support

    What's Onavo Extend you ask? It's a free app that lets you save money on your data plan by compressing unencrypted data between your device and the web. The result is that you consume up to five times less data -- convenient when you're on a tiered / capped data plan, when you're roaming abroad or when you're on a slower 2G network. In addition, the app keeps track of how much data (and money) you save and which apps use that data. This works by setting up a local proxy server (and changing your APN), then connecting to the company's back end which accesses the internet on your behalf. Onavo Extend -- which was released for iOS last year and was launched on Android (Ice Cream Sandwich) at Mobile World Congress -- is gaining CDMA/LTE support today for the new iPad and the iPhone 4S on Verizon and Sprint. We first experienced the app at the Google booth in Barcelona and we've been using it on and off since. We've tested it on several devices, including a Galaxy Nexus HSPA+ and an unlocked iPhone 4S on T-Mobile's network (EDGE only) and it works pretty much as advertised. Want to find out more? Hit the break for a demo video along with the obligatory PR.

    Great free archive utilities are pretty hard to come by on the Mac. Keka is the exception. If OS X's built-in compression utility doesn't do enough for you, Keka could be the answer. Keka's been around since 2009, but only recently made it into the Mac App Store. Unlike Growl, Keka is available both as a paid, US$2 app from the Mac App Store and as a free download from the Keka project site. The two versions will be kept in sync, so there'll always be a free option. Of course if you use it, supporting the developers, either by a donation or buying it in the Mac App Store, will help them continue to update it. Keka allows you to compress files in multiple formats. Zip, 7z, Tar, Gzip and Bzip2 are all included. What's more Keka can extract even more with RAR, 7z, Lzma, Zip, Tar, Gzip, Bzip2, ISO, EXE, CAB, PAX, and even ACE supported. Keka also supports encrypted archives meaning you can password protect compressed files, as well as split archives -- handy when you have file size limitations. Like the Unarchiver and others, you can set Keka as the default extraction client, so files can be decompressed with a double click. If you want to get a bit more advanced, the Keka Dock icon serves as the one-stop shop for compression. Drag and drop files onto it to either decompress or create a new archive in the default format of your choosing. Format and compression method can be changed quickly from a pop-up menu from the Dock icon. It's all very slick.

  • Why you should not be paying for VisualHub (Updated)

    VisualHub was a video conversion application popular several years ago. The app was shuttered in 2008, but it continued to work in OS X until Lion rolled out. Lon Seidman, a Visual Hub customer, recently received an email from online payment processor Kagi that offered a Lion-compatible update to the video conversion app. That sounds great, except this email and the US $4.99 payment was not authorized by VisualHub developer Tyler Loch. Loch did update his app to support Lion, but this new version is available for free from the VisualHub website. Loch even put a warning on his website accusing Kagi of distributing an unauthorized version of vHub Updater and is telling people not to purchase this version. Kagi was the official payment processor for VisualHub when it was an active application so perhaps this is just a misunderstanding and not an attempt by Kagi to fleece VisualHub users. Either way, VisualHub owners should avoid paying Kagi and download the update for free. Update: [Mike Rose] Seidman spoke to Kagi CEO Kee Nethery about the 'unofficial' VisualHub update tool. According to Nethery, his payment processing company often handles simple support questions for software purchasers, even though the responsibility for support actually rests with the developer. In the case of VisualHub, since developer Tyler Loch has stopped distributing his app, Kagi pointed users to Loch's patch instructions on the Techspansion site. Despite the fact that the effort to patch the app is minimal, the process of showing the app package contents and replacing three script files was apparently beyond the "comfort level" of many users contacting Kagi for help. Facing what he describes as a "support nightmare," Nethery took the unprecedented step of building a patcher application that replaced the three script files and also updated the underlying version of ffmpeg used to power the app's compression features. He apparently is frustrated that Loch chose to "walk away from a business" when he stopped developing and selling VisualHub. Macworld also interviewed Nethery and Loch, with similar comments from the Kagi chairman. Loch, however, points out that while there is an open-source descendant of VisualHub (FilmRedux), the original app and the Lion-specific patch files are still copyrighted and closed-source. Loch had no advance notice of Kagi's intent to bundle and sell his patches and did not give his approval. While we can sympathize with Kagi's dilemma and the challenge of responding to upset customers, apparently Nethery forgot that VisualHub is not Kagi's product. The unofficial patcher app issued without Loch's permission is a slap in the face for independent developers who work with Kagi, as up until today they probably believed that their apps were theirs to support or abandon as they saw fit. Whether or not you agree with Loch's decision to close out VisualHub, it is his decision and his alone when to EOL a product. Providing the patches for Lion is a courtesy, not an obligation, and Kagi would be far better off saying "the product is no longer supported, sorry" than pulling this end run. At a bare minimum, a courtesy email to Loch letting him approve or deny permission for the updater app would have been the civil thing to do. Loch's notes on the Lion patch include a wry comment, "Enjoy VisualHub for a little while longer, until Apple discontinues support for AppleScript Studio apps or 32bit apps or non-sandboxed apps." Clearly the zombie support for this discontinued app is a fragile thing, and it can and will break. What will Kagi do then for its frustrated customers? Nothing -- and for better or worse, that's what it should be doing now. [Via Lon Seidman]

  • TUAW's Daily Mac App: BetterZip 2

    Mac OS X has had a zip utility built into it for some time. For extracting stuff other than Zip files, the Unarchiver's your friend. But what about actually compressing and managing archives? That's where BetterZip 2 steps in. BetterZip 2 allows you to open archives without first extracting them, allowing you to see precisely what's inside them before processing them. Often you've got loads of files compressed together, but you only want one -- BetterZip allows you to extract single files from archives without having to extract the whole lot, which can save you time and disk space if it's a really large archive. You can also update archives, adding files into an already compressed archive without having to extract the whole lot first and then re-compressing them together. BetterZip is able to open and extract most common formats, from ZIP to TAR, RAR to JAR, it's got you covered (for a full list see the MAS listing). BetterZip can also compress files into six archive types natively (ZIP, TAR, GZip or BZip2 compressed TAR, XAR and 7-Zip), as well as RAR archives courtesy of an external RAR command-line utility. You can also secure your ZIP, 7-Zip and RAR files with passwords, with WinZip compatible AES-256 encrypted archives at your fingertips. The US$19.99 BetterZip brings a full archive manager to your Mac. It's fast, easy to use and handles all but the most obscure archives. I would like to see the ability to create a few more archive types, but native ZIP and 7-Zip support will see you though most of your archiving needs. BetterZip 2 is available from the Mac App Store for $19.99 with a trial available from the developer's site.

  • ESPN will go all MPEG-4 in July

    For better or worse, ESPN is planning to pull its MPEG-2 feeds at the end of June and transmit to affiliates solely in MPEG-4. Like HBO, ESPN already transmits all of its channels in MPEG-4 via satellite and will save money by cutting out the older backups, but since most cable companies are still sending streams to customers in MPEG-2 (although some are following DirecTV's lead) they'll need to transcode the signal an extra time which could affect the picture quality. Multichannel News mentions ESPN is supplying the necessary Motorola decoders to affiliates that need them, at this point all we can do is wait until July and see if there's any notable difference in sports quality on our end of the pipe.

  • Apple and other music retailers purportedly looking at 24-bit, high-fidelity audio downloads

    Digital downloads, at least pertaining to music, have come a long, long way. The iTunes Music Store in particular has surpassed Walmart as America's leading seller of music, and it's evolved from a DRM-laden mess to a restriction-free(ish) marketplace with higher-than-average bitrate support. But it seems that 256kbps simply isn't high enough. According to unnamed "executives involved in talks," Apple -- as well as a few other digital music retailers -- are currently in discussions with labels to "improve the quality of the song files they sell." Essentially, these retailers are hoping to hawk 24-bit audio rather than the compressed 16-bit files available today, possibly with a price premium attached. The real trick, however, won't be coercing the labels to cooperate, but to retool future devices to actually play back 24-bit files. iTunes itself is already capable of handling 'em, but the iPod, iPhone and a slew of other handheld devices aren't. The report doesn't mention how close to a deal anyone is, but we're guessing it'll be sooner rather than later. Here's hoping the iPhone 5 ships with 128GB of capacity -- we're going to need an awful lot of space to handle those lossless Police albums.

    BetterZip is a utility I might not use every day, but I'm very thankful for it when I need it. It's an archive/compression utility which handles a broad array of archive formats, including ZIP, TAR, GZip, BZip2, and some that you rarely see on a Mac, such as 7-Zip and RAR formats. While the unarchiver built in to OS X can handle quite a few of these formats -- and is what I use on a day-to-day basis -- BetterZip adds a few very useful tools to the mix. BetterZip opens or creates your archive in a file-list format, and you can drag files between Finder and BetterZip to add to or extract from the archive. Creating new archives is just a "File->New" or Command-N away, and you can save them in Zip, TAR, TGZ, TBZ, 7-Zip or XAR formats. While the Finder lets you easily create archives by right-clicking a file selection and choosing "Archive," it doesn't allow you to easily edit the archive or add to it. For quick compression of one or more files for emailing, it's fine and I use it regularly, but for larger archives that need to be more flexible, BetterZip is an excellent choice. BetterZip also makes it easy to search large archives for a single file you're looking for. Read on for more reasons BetterZip is my Friday Favorite ...

    Japan hasn't had a lot of time to get used to the PlayStation 3's Torne digital TV tuner since it launched in March, but it's already getting an update which will add a few more DVR features to improve the experience. Coming in June, v2.00 will enable MPEG-4 AVC compression to squeeze HDTV recordings by as much as 3x their original size as opposed to just copying the original MPEG-2 stream even while playing a game, plus the ability to start watching a program and fast forward/reverse while it's still recording and update the user's PSN status. The free update will be issued in June, until then Torne fans can argue with European and Australian PlayTV owners about whether or not their new features are better than Facebook integration while the U.S. sits out like the ginger kid of a previous marriage it is. %Gallery-93375%

    Even on this side of the Atlantic, we've been hearing complaints about a supposed drop in HD quality from the BBC over the last few months. After installing new encoders in August, the broadcaster slashed its bitrate and viewers have since complained about a variety of PQ issues. Of course the Beeb claims its new hardware is capable of delivering similar quality while saving bandwidth when it went to replace old, out of date technology. In the last few days it's received a bit of a boost, as consumer watchdogs Which? went to the tape, comparing earlier recordings from BBC HD with live broadcasts over Sky and Freesat, claiming any difference between new and old is "tiny, and smaller than the existing differences between any two HD programmes filmed in a studio or on location." Only time will tell if that is enough to calm the commenters on BBC's blogs calling for a return to the old, if your Top Gear and Doctor Who watching has been affected, let us know.

    If there's one Mac application that has seemingly been around forever, it's StuffIt. This compression and archiving utility was the tool to use for compressing files years ago, and I'll still occasionally run into a .sit file extension when pulling up old files. The original application was the source of a bit of Mac folklore, as it was developed and supported for quite a while by a young student by the name of Raymond Lau. Mac OS X did its best to kill off StuffIt by adding built-in support for Zip compression, but the utility has continued to flourish over the years. During the last week, Smith Micro released the newest version of the application, StuffIt Deluxe 2010 (US$79.95, with an introductory price of US$29.95 through October 15, 2009). Since compression has been part of Mac OS X for quite a while, you might think that this application would have limited usefulness. Smith Micro is spinning StuffIt Deluxe 2010 as a better way to share large files over the Internet. How does it work? Read on, my friends...

    Toshiba's Cell-based SpursEngine HD video co-processor has made plenty of appearances within monstrous gaming machines, but this marks the very first time where it has stepped out of the laptop chassis and into a portable enclosure. Granted, the language barrier is killing us here, but it seems as if the Leadtek WinFast HPVC1100 wraps a SpursEngine encoder into an on-the-go solution that can be lugged around with a standard laptop in order to churn through video while on set, in the field or on the road. Other specs include 128MB of RAM, a PCI-Express slot and a weight of 1.54 pounds; there's no word just yet on pricing or availability. One more shot is after the break.[Via Akihabara News]
