Comments Off on Can iOS Activation Lock Be Bypassed?
Two researchers report that they have discovered a way to bypass the activation lock feature in iOS that’s supposed to prevent anyone from using an iPhone or iPad marked as lost by its owner.
The first report came Sunday from an Indian security researcher named Hemanth Joseph, who started investigating possible bypasses after being confronted with a locked iPad he acquired from eBay.
The activation lock gets enabled automatically when users turn on the Find My iPhone feature via iCloud. It links the device to their Apple IDs and prevents anyone else from accessing the device without entering the associated password.
One of the few things allowed from the activation lock screen is connecting the device to a Wi-Fi network, including manually configuring one. Hemanth had the idea of trying to crash the service that enforces the lock screen by entering very long strings of characters in the WPA2-Enterprise username and password fields.
The researcher claims that, after awhile, the screen froze, and he used the iPad smart cover sold by Apple to put the tablet to sleep and then reopen it. This is supposed to restore the state of the tablet from where it was left off, in this case, loading the WPA2 screen again with the long strings of characters filled in.
“After 20-25 seconds the Add Wifi Connection screen crashed to the iPad home screen, thereby bypassing the so-called Find My iPhone Activation Lock,” he said in a blog post.
Hemanth said he reported the issue to Apple on Nov. 4, and the company is investigating it. He tested the bypass on iOS 10.1, which was released on Oct. 24.
Last week, a researcher named Benjamin Kunz Mejri, from German outfit Vulnerability Lab, posted a video showing the same bypass, but on the newer iOS 10.1.1 version.
Kunz Mejri’s method is similar and also involves overflowing the Add Wi-Fi form fields with long strings of characters but also requires rotating the tablet’s screen in order to trigger the crash after the smart cover trick.
Apple has not yet confirmed that issue and did not immediately respond to a request for comment.

Will UMC Chip Shipments Drop In The Fall?
Comments Off on Will UMC Chip Shipments Drop In The Fall?
Foundry UMC is expecting its shipments to fall by five percent in the fourth quarter of 2015, as a result of ongoing inventory adjustments within the industry supply chain.
Revenues for the last part of the year will be adversely affected by an about one per cent drop in wafer ASPs and capacity at its plants will slide to 81-83 per cent in the fourth quarter from 89% in the third.
UMC’s had already lowered capacity in the third quarter. At the beginning of the year it was running at 94 percent.
The company’s revenues decreased 7.1 per cent to $1.07 billion in the third quarter, with gross margin slipping below 20 per cent.
UMC net profits were down 62.9 per cent on quarter, as both operating and non-operating income eroded. This is bad news because in the first three quarters of 2015, UMC’s net profits increased 35.8 per cent from a year earlier.
However UMC is continuing to invest in new capital and will spend $1.8 billion.
CEO Po-Wen Yen said that the continuing IC inventory adjustment will dampen fourth quarter wafer shipments, but UMC continues on the path towards long-term growth.
“Throughout 2015, UMC engineers and Fab12A have worked tirelessly to bring several new 28nm product tape-outs into volume production. “UMC is working to bring a timely conversion of new 28nm requirements into production, which will strengthen our business.”

AMD’s Bet On ARM Does Is Not Working
Comments Off on AMD’s Bet On ARM Does Is Not Working
Buried in the AMD results was a note which seemed to hint that AMD’s plan to flog ARM based server chips was not going very well.
Chief executive Lisa Su admitted that ARM-based server chips have experienced slower-than-expected reception from the owners of data centres and server farms.
AMD delayed its own ARM-based Opteron microprocessor, code-named Seattle, until the fourth quarter of this year. ARM was having a harder time proving itself to the multibillion-dollar market for high-end server chips.
An engineering sample of AMD’s long awaited 8 core server SOC code named “Hierofalcon” has been spotted and tested and according to WCCTech it looked pretty good. Itis based around 8 ARM-64bit A57 cores running at 2.0Ghz. And although Hierofalcon maxes out at frugal TDP of 30W.
So even the promising reviews aren’t enough for AMD to be optimistic about the ARM based gear.
Su said in an analyst conference call that the company expects to see “modest production shipments” of Seattle in the fourth quarter. Meanwhile, AMD’s Intel-compatible “x86″ server chips will be the company’s mainstay product offering for data centres.
She said that AMD was continuing its ARM efforts and is seeing them as a longer term bet.

Semiconductor Sales Still Down In 2015
Comments Off on Semiconductor Sales Still Down In 2015
Semiconductor Sales Still Down In 2015 : :: TheGuruReview.net ::
Sales of semiconductors have remained sluggish during 2015 and look set to drop still further in 2016, according to new research from Gartner.
Last quarter, 2.5 percent growth was expected for 2015, but this has been revised down to a one percent drop in the market. 2016 remains predicted to see a 3.3 percent drop.
“We are continuing to see weakness in end-user electronics demand in response to an uncertain economic environment, which is putting a dampener on 2015 spending,” said Takashi Ogawa, research vice president at Gartner. “Next year we are anticipating DRAM manufacturers to respond to oversupply with dramatic reductions in their investment plans.”
The drop likely comes off the back of weak PC sales too, with Gartner last week revealing that, despite the release of Windows 10, sales of devices slumped 7.7 percent in the third quarter.
The future looks brighter, though, and figures for 2017, 2018 and 2019 show significant growth with the losses of 2015 more than recovered as soon as 2017.
A number of key companies, including Intel, have cut spending in the past quarter against a backdrop of slow demand for electronics. This has led in some cases to semiconductor plants significantly shrinking production to avoid a surplus of obsolete chips in the fast evolving industry.
“In the DRAM market, weak end-market conditions combined with new foundries coming on line at Samsung and SK Hynix have created a weaker market than anticipated in our last forecast,” said Ogawa.
“As a result, we anticipate that DRAM manufacturers will move more quickly from investing in new capacity to a maintenance and upgrade existing capacity mode of operation.”
Meanwhile, NAND memory has actually moved to a small predicted growth of 0.1 percent against a 19.4 percent drop predicted last quarter. The rise of NAND thanks to alliances such as the one between SanDisk and HP has led Gartner to predict a 10 percent shift from DRAM to NAND in the next six months or so, while DRAM manufacturers will begin to slow investments around this time next year.
The news comes after reports that SanDisk is looking to consolidate its business by putting itself up for sale to another market player. WD and Micron are said to be likely buyers.

More Details Uncovered On AMD’s ZEN Cores
Comments Off on More Details Uncovered On AMD’s ZEN Cores
Our well informed industry sources have shared a few more details about the AMD’s 2016 Zen cores and now it appears that the architecture won’t use the shared FPU like Bulldozer.
The new Zen uses a SMT Hyperthreading just like Intel. They can process two threads at once with a Hyperthreaded core. AMD has told a special few that they are dropping the “core pair” approach that was a foundation of Bulldozer. This means that there will not be a shared FPU anymore.
Zen will use a scheduling model that is similar to Intel’s and it will use competitive hardware and simulation to define any needed scheduling or NUMA changes.
Two cores will still share the L3 cache but not the FPU. This because in 14nm there is enough space for the FPU inside of the Zen core and this approach might be faster.
We mentioned this in late April where we released a few details about the 16 core, 32 thread Zen based processor with Greenland based graphics stream processor.
Zen will apparently be ISA compatible with Haswell/Broadwell style of compute and the existing software will be compatible without requiring any programming changes.
Zen also focuses on a various compiler optimisation including GCC with target of SPECint v6 based score at common compiler settings and Microsoft Visual studio with target of parity of supported ISA features with Intel.
Benchmarking and performance compiler LLVM targets SPECint v6 rate score at performance compiler settings.
We cannot predict any instruction per clock (IPC improvement) over Intel Skylake, but it helps that Intel replaced Skylake with another 14nm processor in later part of 2016. If Zen makes to the market in 2016 AMD might have a fighting chance to narrow the performance gap between Intel greatest offerings.

AMD Misses Again
Fabless chipmaker AMD has come up with a mixed set of results for the second quarter. The company managed to make as much cash as the cocaine nose jobs of Wall Street expected, but missed revenue expectations.
In fact its revenues were below the psychologically important billion figure at $942 million.
We knew it was going to be bad. Last week we were warned that the results would be flat. The actual figure was $942m, an 8.5 per cent sequential decline and a 34.6 per cent drop from the same period a year ago.
As you might expect, there are some measures of this not being AMD’s fault. The company is almost entirely dependent on PC sales. Not only have these fallen but don’t look like they are going to pick up for a while.
AMD’s Computing and Graphics division reported revenue of $379m, which was down 54.2 per cent, year-on-year. Its operating loss was $147m, compared to a $6m operating loss for last year’s quarter.
Lisa Su, AMD president and CEO, in a statement said that strong sequential revenue growth in AMD’s enterprise, embedded, and semi-custom segment and channel business was not enough to offset near-term problems in its PC processor business. This was due to lower than expected consumer demand that impacted sales to OEMs, she said.
“We continue to execute our long-term strategy while we navigate the current market environment. Our focus is on developing leadership computing and graphics products capable of driving profitable share growth across our target markets,” she added.
In the semi-custom segment, AMD makes chips for video game consoles such as the Nintendo Wii U, Microsoft Xbox One, and Sony PlayStation 4 consoles. That segment did reasonably well, up 13 percent from the previous quarter but down 8 percent from a year ago.
But AMD’s core business of processors and graphics chips fell 29 percent from the previous quarter and 54 percent from a year ago. AMD said it had decreased sales to manufacturers of laptop computers.
Figures like this strap a large target on AMD’s back with a sign saying “take me over” but AMD is not predicting total doom yet.
For the third quarter, AMD expects revenue to increase 6 percent, plus or minus 3 percent, sequentially, which is a fairly conservative outlook given the fact that Windows 10 is expected to push a few sales its way.
AMD supplies chips to the Nintendo Wii U, Microsoft Xbox One, and Sony PlayStation 4 consoles and these seem to be going rather well.
Is The Chip Market On The Rebound
Don’t let anyone fool you, the chipmarket is still not doing that well and there are a few problems to be sorted out before real money will be made.
FC Tseng, vice chairman for foundry VIS said that handset makers have too much inventory in their warehouses and the much hyped IoT market boom has not yet arrived.
In fact it is looking like 2015 will not be as good as 2014, which was pretty good at least as far as VIS was concerned.
Semiconductor demand for IoT applications will emerge, but no one has really worked out what the key drivers of IoT market growth will be, Tseng said.
Smartphones, devices such as watches, bracelets and glasses are all being identified as the popular applications when it comes to wearables and the Internet of Things.
VIS forecast that the global 2015 semiconductor market will increase 5 per cent in production value to $358 bn, while the foundry sector will grow by a larger 10 per cent on year to about S$50 bn.
VIS chairman and president Leuh Fang warned that the company has seen a low visibility of customer orders for the third quarter of 2015.
VIS reported record revenues and profits for 2014 and has been spending on capital expenditure like a mad thing in 2015.
Did AMD Commit Fraud?
AMD must face claims that it committed securities fraud by hiding problems with the bungled 2011 launch of Llano that eventually led to a $100 million write-down, a US court has decided.
According to Techeye US District Judge Yvonne Gonzales Rogers said plaintiffs had a case that AMD officials misled them by stating in the spring of 2011 and will have to face a full trial.
The lawsuit was over the Llano chip, which AMD had claimed was “the most impressive processor in history.”
AMD originally said that the product launch would happen in the fourth quarter of 2010, sales of the Llano were delayed because of problems at the company’s chip manufacturing plant.
The then Chief Financial Officer Thomas Seifert told analysts on an April 2011 conference call that problems with chip production for the Llano were in the past, and that the company would have ample product for a launch in the second quarter.
Press officers for AMD continued to insist that there were no problems with supply, concealing the fact that it was only shipping Llanos to top-tier computer manufacturers because it did not have enough chips.
By the time AMD ramped up Llano shipments in late 2011, no one wanted them any more, leading to an inventory glut.
AMD disclosed in October 2012 that it was writing down $100 million of Llano inventory as not shiftable.
Shares fell nearly 74 percent from a peak of $8.35 in March 2012 to a low of $2.18 in October 2012 when the market learned the extent of the problems with the Llano launch.
Intel Gives Exascale A Boost
Intel’s exascale computing efforts have received a boost with the extension of the company’s research collaboration with the Barcelona Supercomputing Center.
Begun in 2011 and now extended to September 2017, the Intel-BSC work is currently looking at scalability issues with parallel applications.
Karl Solchenbach, Intel’s director, Innovation Pathfinding Architecture Group in Europe said it was important to improve scalability of threaded applications on many core nodes through the OmpSs programming model.
The collaboration has developed a methodology to measure these effects separately. “An automatic tool not only provides a detailed analysis of performance inhibitors, but also it allows a projection to a higher number of nodes,” says Solchenbach.
BSC has been making HPC tools and given Intel an instrumentation package (Extrae), a performance data browser (Paraver), and a simulator (Dimemas) to play with.
Charlie Wuischpard, VP & GM High Performance Computing at Intel said that the Barcelona work is pretty big scale for Chipzilla.
“A major part of what we’re proposing going forward is work on many core architecture. Our roadmap is to continue to add more and more cores all the time.”
“Our Knights Landing product that is coming out will have 60 or more cores running at a slightly slower clock speed but give you vastly better performance,” he said.
Can BB Benefit From The WhatsApp Deal?

Comments Off on Can BB Benefit From The WhatsApp Deal?
Facebook Inc’s awe-inspiring $19 billion bid for fast-growing mobile-messaging startup WhatsApp sent shares of BlackBerry Ltd surging after the closing bell as early as Wednesday, as investors were cheered by the lofty valuation for the messaging platform.
The deal sent shares in BlackBerry up as much as 9 percent in trading after the bell because it put a rough valuation metric around the smartphone maker’s own BlackBerry Messaging service.
BlackBerry Messaging, or BBM as it is more commonly known, was a pioneering mobile-messaging service, but its user base has failed to keep pace with that of WhatsApp, in part because BlackBerry had long refused to open the service to users on other platforms.
WhatsApp, with a user base of some 450 million, has grown rapidly. Its service works on Apple Inc’s iOS platform, Google Inc’s market-dominating Android operating system, along with devices powered by both the Windows and BlackBerry operating systems.
BBM remains popular, even though BlackBerry devices have waned in popularity. Late last year, the Waterloo, Ontario-based smartphone maker finally opened the messaging platform to users of iPhones and Android devices, and the service currently has over 80 million active users.
However, investors have attributed little value to the asset within the company. On Tuesday, Raymond James analyst Steven Li, in a note to clients, broke out a sum-of-parts valuation of the company and pegged the value of BBM at merely $240 million, or $3 per user.
Facebook’s valuation of WhatsApp translates into roughly $42 per user, and that could lead investors and analysts to rethink their valuation of the asset within BlackBerry.
BlackBerry has given no indication it is keen to sell the asset. While there has been some speculation that BlackBerry may seek to carve out the unit, or even sell it, the company’s new Chief Executive John Chen has so far said that BBM remains a core asset for the company.
