3D Printers Shown To Emit Potentially Harmful Nanosized Particles 180

Posted by Soulskill
from the price-you-pay-for-having-a-plastic-version-of-your-own-head dept.
An anonymous reader writes "A new study by researchers in the Built Environment Research Group at the Illinois Institute of Technology shows that commercially available desktop 3D printers can have substantial emissions of potentially harmful nanosized particles in indoor air. Many desktop 3D printers rely on a process where a thermoplastic feedstock is heated, extruded through a small nozzle, and deposited onto a surface to build 3D objects. Similar processes have been shown to have significant aerosol emissions in other studies using a range of plastic feedstocks, but mostly in industrial environments. In this study, researchers measured ultrafine particle concentrations resulting from a popular commercially available desktop 3D printer using two different plastic feedstocks inside an office. Ultrafine particles (or UFPs) are small, nanosized particles less than 100 nanometers in diameter. Inhalation of UFPs may be important from a health perspective because they deposit efficiently in the lung and can even translocate to the brain. Estimates of emission rates of total UFPs in this study were high, ranging from about 20 billion particles per minute for a 3D printer utilizing a lower temperature polylactic acid (PLA) feedstock to about 200 billion particles per minute for the same type of 3D printer utilizing a higher temperature acrylonitrile butadiene styrene (ABS) feedstock. The emission rates were similar to those measured in previous studies of several other devices and indoor activities, including cooking on a gas or electric stove, burning scented candles, operating laser printers, or even burning a cigarette."

Around 2,000 Fukushima Workers At Risk of Thyroid Cancer 124

Posted by Soulskill
from the percentage-points dept.
mdsolar writes "Around 2,000 people who have worked at Japan's wrecked Fukushima nuclear plant face a heightened risk of thyroid cancer, its operator said Friday. Tokyo Electric Power (TEPCO) said 1,973 people — around 10 percent of those employed in emergency crews involved in the clean-up since the meltdowns — were believed to have been exposed to enough radiation to cause potential problems. The figure is a 10-fold increase on TEPCO's previous estimate of the number of possible thyroid cancer victims and comes after the utility was told its figures were too conservative. Each worker in this group was exposed to at least 100 millisieverts of radiation, projections show."

ASUS PQ321Q Monitor Brings Multi-Stream Tiled Displays Forward 94

Posted by timothy
from the eyestrain-be-gone dept.
Vigile writes "While 4K displays have been popping up all over the place recently with noticeably lower prices, one thing that kind of limits them all is a 30 Hz refresh rate panel. Sony is selling 4K consumer HDTVs for $5000 and new-comer SEIKI has a 50-in model going for under $1000 but they all share that trait — HDMI 1.4 supporting 3840x2160 at 30 Hz. The new ASUS PQ321Q monitor is a 31.5-in 4K display built on the same platform as the Sharp PN-K321 and utilizes a DisplayPort 1.2 connection capable of MST (multi-stream transport). This allows the screen to include two display heads internally, showing up as two independent monitors to some PCs that can then be merged into a single panel via AMD Eyefinity or NVIDIA Surround. Thus, with dual 1920x2160 60 Hz signals, the PQ321Q can offer 3840x2160 at 60 Hz for a much better viewing experience. PC Perspective got one of the monitors in for testing and review and found that the while there were some hurdles during initial setup (especially with NVIDIA hardware), the advantage of a higher refresh rate made the 4K resolution that much better."

Collision Between Water and Energy Is Underway, and Worsening 189

An anonymous reader writes "This article is an eye opening perspective on another side effect of power generation — water usage: 'More than 40 percent of fresh water used in the United States is withdrawn to cool power plants. Renewable energy generally uses far less water, but there are glaring exceptions, such as geothermal and concentrating solar.' The article also mentions that power plants have to shut down if the incoming water is too warm to cool the plant. 'Also, even though some newer plants might use far less water, they could find that there’s far less water available as water temperatures go up and water flows go down. Another study found that nearly half of 423 U.S. plants were at risk of lower power output during droughts because their intake pipes for water were less than 3 meters below the surface.'"

BitTorrent Sync Beta Released 69

Posted by Soulskill
from the capitalizing-on-unrest dept.
Nerval's Lobster writes "BitTorrent Sync has reached its Beta milestone. The tool, which allows for secure file-syncing between devices, has been under development for quite some time: BitTorrent released a limited pre-Alpha program in January, planning to use any feedback to refine the software before release. Key features include the use of peer-to-peer technology for direct synchronization, rather than storing files in the cloud—a key differentiator from similar storage services on the market. 'It fits into our overall goal of making a better Internet using P2P,' BitTorrent Inc. told TorrentFreak when that pre-Alpha rolled out. In the intervening months, of course, former federal contractor Edward Snowden leaked a variety of top-secret documents about NSA surveillance to The Guardian, kicking off several weeks' worth of discussions and handwringing over government snooping. Several of those documents suggested that an NSA program codenamed PRISM siphoned user data from nine major technology companies, including Google and Microsoft; the named companies have stridently denied any involvement. Those revelations about the NSA—even if totally unsurprising to the paranoid—could kick off renewed interest in software tools capable of securing data against prying eyes. In other words, this could be just the moment for something like BitTorrent Sync to hit the market. 'Sync is a response to what we see as real, fundamental challenges to personal data movement: the limitations on speed, size, space, privacy, and security that come with cloud dependency,' read a July 17 note on the BitTorrent Blog."

San Onofre's Closure: What Was Missed 88

Posted by Unknown Lamer

Lasrick writes "John Mecklin explores the context that was missed when the LA Times and the San Diego Union Tribune reported on the closing of the remaining two San Onofre nuclear reactors: 'U-T San Diego published a similar flurry of well-reported stories that covered the basics of the reasons for the closure, as well as the impact on consumers, workers, and the electricity supply. At both papers, coverage included infographics that effectively explained the problem that forced the plant to close—vibration that caused wear in tubes for the plant's steam generators. (The Times's tick-tock takeout on the history of the steam generator snafu, published in July, is especially comprehensive.) The specifics of the San Onofre closing were covered well and thoroughly. The context within which those basics reside, however, was far less well-examined, and the two major newspapers closest to the San Onofre plant both therefore missed a real opportunity to inform readers about the major energy choices California and the country will need to make in the coming decade.' Excellent work at the Columbia Journalism Review."

Casting a Jaundiced Eye On AnTuTu Benchmark Claims Favoring Intel 82

Posted by timothy
from the surely-there's-a-perfectly-innocent-explanation dept.
MojoKid writes "Recently, industry analysts came forward with the dubious claim that Intel's Clover Trail+ low power processor for mobile devices had somehow seized a massive lead over ARM's products, though there were suspicious discrepancies in the popular AnTuTu benchmark that was utilized to showcase performance. It turns out that the situation is far shadier than initially thought. The version used in testing with the benchmark isn't just tilted to favor Intel — it seems to flat-out cheat to accomplish it. The new 3.3 version of AnTuTu was compiled using Intel's C++ Compiler, while GCC was used for the ARM variants. The Intel code was auto-vectorized, the ARM code wasn't — there are no NEON instructions in the ARM version of the application. Granted, GCC isn't currently very good at auto-vectorization, but NEON is now standard on every Cortex-A9 and Cortex-A15 SoC — and these are the parts people will be benchmarking. But compiler optimizations are just the beginning. Apparently the Intel code deliberately breaks the benchmark's function. At a certain point, it runs a loop that's meant to be performed 32x just once, then reports to the benchmark that the task completed successfully. Now, the optimization in question is part of ICC (the Intel C++ compiler), but was only added recently. It's not the kind of procedure you'd call by accident. AnTuTu has released an updated "new" version of the benchmark in which Intel performance drops back down 20-50%. Systems based on high-end ARM devices again win the benchmark overall, as they did previously."

An anonymous reader writes "I've a cheap but low latency mouse (A4Tech) and I noticed my trusty old wired Logitech PS/2 keyboard seems at least 50ms slower (if not more) than the mouse when I test with those reaction time sites. I even increased finger travel distance over my mouse button to make it fairer and the difference still remains. So either the tests are slower with keyboards or my keyboard is high latency. Assuming the latter any suggestions for a good reasonably priced gaming keyboard? Extra function keys might be nice but since my hands aren't big what would be better is being able to output a custom key/combo if you hold down (special?) keys while pressing another key. For example I could configure it so if I hold down "Special Key 1" with pinkie or thumb and press 4 it actually outputs 9, and if I hold down shift as well it outputs shift+9 (and not just 9). Being able to replace the capslock key function and have it behave as another key (or a special modifier) would be a bonus — I've never needed capslock and have probably used it more by mistake than for its normal function, or to test how badly a PC has hung."

New Analysis Casts Doubt On Intel's Smartphone Performance vs. ARM Devices 94

MojoKid writes "A few weeks ago, the analyst company ABI Research published a report claiming that Intel's new CloverTrail+ platform (dual-core Medfield) for smartphones was significantly faster and more power efficient than anything ARM's various partners were shipping. If you follow the smartphone market, that was a very surprising claim. Medfield was a decent midrange platform when it launched in 2012, but Intel made it clear that its goal for Medfield was to compete with other platforms in its division — not seize the performance crown outright. Further investigation by other analysts has blown serious holes in the ABI Research report. Not only does it focus on a single, highly questionable benchmark (AnTuTu), the x86 version of that benchmark is running different code than the ARM flavors. Furthermore, the recently released Version 3.3 of the test is much faster on Intel hardware than on any of the other platforms. But even with those caveats in place, the ABI Research report is bad science. Single-source performance comparisons almost inevitably are."

Nerval's Lobster writes "Just in case you haven't been keeping up with the latest in five-dimensional digital data storage using femtocell-laser inscription, here's an update: it works. A team of researchers at the University of Southampton have demonstrated a way to record and retrieve as much as 360 terabytes of digital data onto a single disk of quartz glass in a way that can withstand temperatures of up to 1000 C and should keep the data stable and readable for up to a million years. 'It is thrilling to think that we have created the first document which will likely survive the human race,' said Peter Kazansky, professor of physical optoelectronics at the Univ. of Southampton's Optical Research Centre. 'This technology can secure the last evidence of civilization: all we've learnt will not be forgotten.' Leaving aside the question of how many Twitter posts and Facebook updates really need to be preserved longer than the human species, the technology appears to have tremendous potential for low-cost, long-term, high-volume archiving of enormous databanks. The quartz-glass technique relies on lasers pulsing one quadrillion times per second though a modulator that splits each pulse into 256 beams, generating a holographic image that is recorded on self-assembled nanostructures within a disk of fused-quartz glass. The data are stored in a five-dimensional matrix—the size and directional orientation of each nanostructured dot becomes dimensions four and five, in addition to the usual X, Y and Z axes that describe physical location. Files are written in three layers of dots, separated by five micrometers within a disk of quartz glass nicknamed 'Superman memory crystal' by researchers.

3-D Structures Built Out of Liquid Metal At Room Temperature 72

ph4cr writes with news that a few researchers have discovered an alloy that allows them to print 3D structures from liquid metal at room temperature. From the article: "'It's difficult to create structures out of liquids, because liquids want to bead up. But we’ve found that a liquid metal alloy of gallium and indium reacts to the oxygen in the air at room temperature to form a "skin" that allows the liquid metal structures to retain their shapes,' says Dr. Michael Dickey, an assistant professor of chemical and biomolecular engineering at NC State and co-author of a paper describing the work. ... One technique involves stacking droplets of liquid metal on top of each other, much like a stack of oranges at the supermarket. The droplets adhere to one another, but retain their shape – they do not merge into a single, larger droplet. ... Another technique injects liquid metal into a polymer template, so that the metal takes on a specific shape. The template is then dissolved, leaving the bare, liquid metal in the desired shape. The researchers also developed techniques for creating liquid metal wires, which retain their shape even when held perpendicular to the substrate." The paper is available online.

big.LITTLE: ARM's Strategy For Efficient Computing 73

Posted by Soulskill
from the i-see-what-you-did-there dept.
MojoKid writes "big.LITTLE is ARM's solution to a particularly nasty problem: smaller and smaller process nodes no longer deliver the kind of overall power consumption improvements they did years ago. Before 90nm technology, semiconductor firms could count on new chips being smaller, faster, and drawing less power at a given frequency. Eventually, that stopped being true. Tighter process geometries still pack more transistors per square millimeter, but the improvements to power consumption and maximum frequency have been falling with each smaller node. Rising defect densities have created a situation where — for the first time ever — 20nm wafers won't be cheaper than the 28nm processors they're supposed to replace. This is a critical problem for the mobile market, where low power consumption is absolutely vital. big.LITTLE is ARM's answer to this problem. The strategy requires manufacturers to implement two sets of cores — the Cortex-A7 and Cortex-A15 are the current match-up. The idea is for the little cores to handle the bulk of the device's work, with the big cores used for occasional heavy lifting. ARM's argument is that this approach is superior to dynamic voltage and frequency scaling (DVFS) because it's impossible for a single CPU architecture to retain a linear performance/power curve across its entire frequency range. This is the same argument Nvidia made when it built the Companion Core in Tegra 3."

from the veil-spass-beim-kuli dept.
DeviceGuru writes with a snippet from LinuxGizmos: "A Linux-based digital pen from German startup Lernstift will go live on Kickstarter on July 10 for about 115 Euros, or $148. The Lernstift pen incorporates an ARM Cortex processor, a WiFi module, and a motion sensor, and is designed to correct penmanship, spelling, and grammar errors as you write. A set of 3D motion sensors, including a gyroscope, accelerometer, and magnetometer help the smartpen's embedded Linux computer calculate the pen's 3D movements and generate 2D vectors. Kickstarter supporters pledging 99 Pounds (about 115 Euros, or $148 U.S.) will receive the first shipment of pens later this year, and standard pricing is expected to start at 130-150 Euros when production devices ship in early 2014."

Got Malware? Get a Hammer! 254

from the sorry-but-it's-the-only-way dept.
FuzzNugget writes "After the Economic Development Administration (EDA) was alerted by the DHS to a possible malware infection, they took extraordinary measures. Fearing a targeted attack by a nation-state, they shut down their entire IT operations, isolating their network from the outside world, disabling their email services and leaving their regional offices high and dry, unable to access the centrally-stored databases. A security contractor ultimately declared the systems largely clean, finding only six computers infected with untargeted, garden-variety malware and easily repaired by reimaging. But that wasn't enough for the EDA: taking gross incompetence to a whole new level, they proceeded to physically destroy $170,500 worth of equipment (PDF), including uninfected systems, printers, cameras, keyboards and mice. After the destruction was halted — only because they ran out of money to continue smashing up perfectly good hardware — they had racked up a total of $2.3 million in service costs, temporary infrastructure acquisitions and equipment destruction."

Former Valve Hardware Designer Recounts Management Difficulties 224

Posted by Unknown Lamer
from the lord-of-the-flies dept.
DavidGilbert99 writes "Jeri Ellsworth has opened up about her time at games developer Valve and has hit out strongly at the so-called flatpack management structure. She says that despite Valve's claims of a democratic structure, there is a layer of powerful management in place and when she was fired she felt like she had been stabbed in the back. 'If I sound bitter, it's because I am. I am really, really bitter. They promised me the world and then stabbed me in the back.'" Develop Online has a good transcript. In the end, Gabe Newell at least let her team keep the rights to their augmented reality hardware. She also notes that she still loves Valve, but the management and bonus structure resulted in communication breakdowns at Valve's size. It does seem that a flat structure can work: Andy Wingo has been weblogging about working at Igalia and seems pretty positive about the experience.

cylonlover writes "Li-ion batteries may be ok for your smartphone, but when it comes to large-scale energy storage, the priorities suddenly shift from compactness and cycling performance (at which Li-ion batteries excel) to low cost and environmental feasibility (in which Li-ion batteries still have much room for improvement). A new 'wood battery' could allow the emerging sodium-ion battery technology to fit the bill as a long-lasting, efficient and environmentally friendly battery for large-scale energy storage."

Progress On the Open Laptop 57

An anonymous reader writes "Last October, we discussed Andrew 'bunnie' Huang's effort to build a complete open hardware laptop, called the Novena. bunnie has now posted a progress report on the laptop's design and construction, showing the latest revision of the board, the display, and a hack to use it as a secure router. bunnie says, 'At the end of the day, we're having fun building the laptop we always wanted — it's now somewhere between a python-scriptable oscilloscope, logic analyzer, and a laptop. I think it will be an indispensable tool for hacking, particularly for doing signal analysis which requires coordination across multiple protocol layers, complex trigger conditions and/or feedback stimulus loops. As for the inevitable question about if these will be sold, and for how muchonce we're done building the system (and, "done" is a moving target — really, the whole idea is this is continuously under development and improving) I'll make it available to qualified buyers. Because it's open-source and a bit quirky, I'm shy on the idea of just selling it to anyone who comes along wanting a laptop. I'm worried about buyers who don't understand that "open" also means a bit of DIY hacking to get things working, and that things are continuously under development."

An anonymous reader writes "South African Quentin Harley has picked up the $20,000 Gada Uplift prize for making the open source RepRap 3D printer design easier to build, cheaper to construct, and — most importantly — capable of printing more of its own parts. Lots of background on Harley and his RepRap Morgan are available on his website." A further goal of the RepRap Morgan project is to replace the Prusa Mendel as the default RepRap model. And they are on track to hit less than $100 in parts, excluding the printing bed. You can grab the hardware design and the controller firmware over at Github.

Man Campaigns For Addition of 'Th' Key To Keyboard 258

beaverdownunder writes "Melbourne restauranteur Paul Mathis has developed a one-character replacement for the word 'The' – effectively an upper-case 'T' and a lower-case 'h' bunched together so they share the upright stem – and an app that puts it in everyone's hand by allowing users to download an entirely new keyboard complete not just with his 'Th' symbol, but also a row of keys containing the 10 or 15 (depending on the version) most frequently typed words in English. Mathis has already copped criticism from people who claim he is attempting to trademark a symbol that is part of the Serbian Cyrillic alphabet (pronounced 'tshe,' the letter represents the 'ch' sound found in the word 'chew')."

ARMs Race: Licensing vs. Manufacturing Models In the Mobile Era 54

Posted by timothy
from the everyone-knows-salsa-works-better-on-chips dept.
MojoKid writes "The semiconductor market for mobile and hand-held devices has changed dramatically in the past six years and ARM has had to evolve along side it. ARM's IP focus allows it to dedicate all its resources to building a great design rather than committing to any single manufacturing process node, customer, or foundry. Architectural design and implementation is done very much in partnership with both foundries (TSMC, GlobalFoundries) and licensees like Samsung or Qualcomm. The difference between the way Intel goes to market and ARM's model is more nuanced than the simple ownership of manufacturing facilities. Owning its own fab means that Intel can tweak process technology to match the particulars of a given architecture (and vice-versa). It also gives the company far more flexibility when planning future nodes. If Intel feels that integrating Peanut Butter Silicon on Insulator (PB-SOI) is the best way to hit its performance and power consumption targets at 14nm, for example, it can make that happen internally. ARM, in contrast, is limited by the decisions of the foundry manufacturers it partners with."

Ask Slashdot: Permanent Preservation of Human Knowledge? 277

from the you-mean-facebook-won't-survive-the-apocalypse? dept.
Wayne2 writes "While there have been many attempts to preserve human knowledge in electronic format, it occurred to me that these attempts all assume that human civilization remains more or less intact. Given humanity's history of growth and collapse with knowledge repeatedly gained then lost, has anyone considered a more permanent solution? I realize that this could be very difficult and/or expensive depending on how long we want to preserve the information and what assumptions we make regarding posterity's ability to access it. Alternatively, are we, as a species, willing to start over if we experience a catastrophe, pandemic, etc. of significant magnitude on a global scale that derails our progress and sends us back to the dark ages or worse?"

Underground 'Wind Mines' Could Keep Datacenters Powered 109

Posted by Soulskill
from the thar-be-wind-in-them-thar-hills dept.
Nerval's Lobster writes "Major IT vendors have been including custom-built wind- and solar-power farms in their datacenter construction plans. But while wind and solar power may be clean, they're often unreliable, especially by the standards of datacenters that need a way to keep operating through any unexpected surges or drops in power. How about saving the wind that generates the power? That might work, according to researchers at the federal Bonneville Power Administration (BPA), and U.S. Department of Energy's Pacific Northwest National Laboratory. A study published in February (PDF) outlined the potential benefit of pumping pressurized air into caverns deep underground as a way to store wind energy, then letting it out whenever demand spikes, or the wind drops, and the above-ground facilities need help spinning enough turbines to keep power levels steady. The technique, called Compressed Air Energy Storage (CAES) isn't new: existing CAES plants in Alabama and Huntorf, Germany (built in 1991 and 1978, respectively) store compressed air in underground salt caverns hollowed out by solution mining (pumping salt-saturated water out of concentrations of salt buried far underground and replacing it with fresh water). But implementing such a technique for datacenters might take a little work. The BPA and the Pacific Northwest National Laboratory have already identified, and are evaluating, sites in the Pacific Northwest that would be suitable for CAES underground reservoirs; the first, which could be located in Washington's Columbia Hills could—via existing CAES technology—store enough compressed air to generate a steady 207MW for 40 days of continuous usage, ultimately delivering 400 additional hours without adding any compressed air."

Breaking Up With MakerBot 185

Posted by Soulskill
from the caught-cheating-with-stratasys dept.
An anonymous reader writes "Sanders Kleinfeld explains how his experiences with a Makerbot device led him to the decision that 3-D printing hasn't quite arrived as a legitimate, consumer-friendly technology. Quoting: 'Waiting five hours for your Yoda feels like an eternity; you can play approximately sixty rounds of Candy Crush Saga in that same timeframe (although arguably, staring blankly at the MakerBot is equally intellectually stimulating). To make matters worse, I’d estimate MakerBot’s failure rate fell in the range of 25%–33%, which meant that there was around a one-in-three chance that two hours in, your Yoda print would fail, or that it would finish but once it was complete, you’d discover it was warped or otherwise defective. ... The first-generation MakerBot Replicator felt too much like a prototype, as opposed to a proven, refined piece of hardware. I look forward to the day when 3D printers are as cheap, ubiquitous, and easy to use as their 2D inkjet printer counterparts.'"

AOC's 21:9 Format, 29" IPS Display Put To the Test At 2560x1080 217

Posted by Soulskill
from the how-does-quake-3-look-on-it dept.
MojoKid writes "Ask any person who owns a dual-monitor setup and they'll likely tell you they couldn't fathom going back to a single display. But what if you could enjoy all the benefits of a dual-monitor configuration from a single monitor? Would you be game to reclaiming some desk space by trading in two panels for a single display? AOC aims to answer that question with its new 29-inch Q2963PM LCD monitor. Armed with an UltraWide IPS panel, this LED-backlit monitor boasts a 2560x1080 resolution with 21:9 aspect ratio, providing users with an extra wide panoramic view. With features like picture-in-picture (PIP) and picture-by-picture (PBP) built-in, workcaholics can multitask the night away from multiple video sources with plenty of horizontal real estate to play with. The funky aspect ratio limits the appeal of the Q2963PM for gamers currently; though if developers were to jump on board, a 21:9 monitor could offer a wider field-of-view of the action."

Apple Powering Nevada Datacenter With Solar Farm 104

Posted by Soulskill
from the located-for-easy-access-to-vegas dept.
Nerval's Lobster writes "Apple's Nevada data center has been in the works for quite some time: a 2,200-acre plot outside of Reno will host a 90,000-square-foot datacenter that, in turn, will support the tech giant's cloud services. Apple will reportedly spend $1 billion over the next decade on the facilities, in return for significant tax abatements at the city, county and state levels. It will also fund and build a 137-acre solar farm, managed in conjunction with NV Energy, to power the datacenter (it will generate approximately 43.5 million kilowatt hours of electricity). The Reno datacenter will be the third Apple cloud facility in the U.S. that is powered largely or entirely by solar power. Sixty percent of the power for Apple's North Carolina datacenter comes from an existing solar-power farm near the facility; an Apple datacenter in Oregon uses solar power for part of its power load, but also uses power from wind and hydroelectric sources."

Firefox OS Smartphones Launching, But Will Anyone Buy One? 127

Posted by samzenpus
from the making-the-call dept.
Nerval's Lobster writes "Mozilla and its hardware partners have begun launching the first Firefox OS smartphones, starting with Spain's Telefonica releasing the ZTE Open later this week. A lightweight mobile OS based on HTML5, Firefox OS (once known as 'Boot to Gecko') offers a user interface instantly familiar to anyone who's used Google Android or Apple iOS: in addition to home-screens of individual apps arranged on a grid, features include messaging, email, built-in social-networking, maps, and the Firefox Web browser. There's also Firefox Marketplace, an online storefront of HTML5 apps; early apps include Twitter, Facebook, AccuWeather, and a handful of games. But can Firefox OS make any headway in a mobile-device crowded with options? At this February's Mobile World Congress, Mozilla claimed that some 17 operators around the world have committed to the Firefox OS initiative, including China Unicom, Sprint, MegaFon, and the Telecom Italia Group. But many of those operators released rather ambiguous statements about whether they would launch an actual Firefox OS smartphone. Tony Cripps, principal device analyst at Ovum, wrote in a research note earlier this year that 'the real acid test for Firefox OS and its long-term prospects is the quality of the software itself and the user and developer experiences that it fosters.' In other words, Mozilla and its partners need to produce some quality devices, paired with a variety of spectacular apps. Some early reviews of the ZTE Open weren't good, to put it mildly, with The Verge citing: 'unremarkable hardware' and a 'laggy' OS. But that doesn't mean future phones can't go toe-to-toe against anything else on the market, provided Mozilla and its partners provide solid support and marketing."
