First Exaflops supercomputer in 2020

 WHY ?
This prediction is based on IBM results in low power consumption supercomputer delivery. IBM was however unable, even under strict contract terms delivering anything sooner than this.

Software?? Later, as you already know from personal experience. In 2022-2023 time frame.
99% BAD HARDWARE WEEK: Exaflops functionality is related with extremly sensitivity to hardware and sofware failures.

UPDATE 2: China's 5-Year Plan Revealed

And China has dedicated the funding and the economic pressure to accomplish those goals, according to IDC.

UPDATE 1: IBM’s chip business sale gets national security scrutiny

 Retired U.S. Army Brig. Gen. John Adams, who authored a report last year for an industry group about U.S. supply chain vulnerabilities and national security, said the sale "needs to be closely studied and scrutinized."
It's unclear how capable Iran's supercomputing capabilities are at this point; Iran's Amirkabir University of Technology, the home of the IHPCRC, had in 2010 a system with 4,600 CPUs, but it did not identify the processor maker. 
99% BAD HARDWARE WEEK: More about chip hacking read at recent bad hardware week posts. But taking chips for granted and don't think who is the SUPPLIER of critical rare earth materials for them is really short sighted national security.
In mutual partnership Abu Dhabi further gets IBM's RF portolio. Congrats.

IBM to pay Globalfoundries $1.5 billion to take its fab !

After AMD , IBM becomes fabless too.

Future of the Ethernet

  10 times faster in the next 10 years.
Well, used to rise faster some 20 years ago.

See invisible: Canon developing multi-layer CCD

Canon's multi-layer CCD. The CCD will be 2/3" diagonally.
99% BAD HARDWARE WEEK: April Fools Or not ? It is however patented in 2011. Perhaps Canon deliver it in 2015.
25 mega pixels x3 color sensor should be great at full frame.  Equivalent at current 24 megapixels at micro 4/3 format too. Lets wait.

How secure your iPhone 5 and 6 are ?

•All attributes are now encrypted (not only password)
•AES-GCM is used instead of AES-CBC

AES-GCM has the following problems:
  • In the case of nonce reuse both integrity and confidentiality properties are violated. If the same nonce is used twice, an adversary can create forged ciphertexts easily.
  • When short tags are used, it is rather easy to produce message forgeries. For instance, if the tag is 32 bits, then after $2^{16}$ forgery attempts and $2^{16}$ encryptions of chosen plaintexts (also of length $2^{16}$), a forged ciphertext can be produced. Creation of forgeries can be instantaneous when enough forgeries have been found.
  • GCM security proof has a flaw. It has been repaired recently, but the new security bounds are far worse for nonces not 12 bytes long;
  • GCM implementations are vulnerable to timing attacks if they do not use special AES instructions. The vulnerability remains even if the AES itself is implemented in constant-time. Constant-time implementations of GCM exist, but they are rather slow.
  • GCM restricts the total amount of data encrypted on a single key to 60 GBytes, which might be undesirable in the future.
99% BAD HARDWARE WEEK: AES-GCM uses 128 bit keys. Thus you can't consider your iPhone 6 data TOP SECRET, but secret. At least under NSA suit B classification. Secret means the same as for iPhone 4 and earlier versions: Open to law enforcement upon request !. SEEMS THAT iPhone IS STILL MORE BENDABLE TOWARD THOSE REQUESTS THAN ADVERTISED BY APPLE !
