Five building blocks of a data-driven culture

Five building blocks of a data-driven culture

How can organizations leverage data as a strategic asset? Data comes at a high price. Businesses must pay for data collection and cleansing, hosting and maintenance, salaries of data engineers, data scientists and analysts, risk of breach and so on.

The line items add up. However, if done well, a thriving data-driven organization can reap huge rewards.

AES-256 crypto cracked in 50 secs using 200 Euros of kit one metre away

AES-256 crypto cracked in 50 secs using 200 Euros of kit one metre away

Sideband attacks that monitor a computer's electromagnetic output to snaffle passwords are nothing new. They usually require direct access to the target system and a lot of expensive machinery -- but no longer.

Researchers at Fox-IT have managed to crack AES (Advanced Encryption Standard) 256 encryption keys from a distance of 1 metre (3.3 feet) -- using €200 (~US$224) worth of parts obtained from a standard electronics store -- just by measuring electromagnetic radiation.

Getting Noisy Encoders Under Control

Getting Noisy Encoders Under Control

With the proper care, even inexpensive encoders can be made to operate reliably.

The interrupts were set to trigger on the RISING edge. That means that the normally high encoder pulses had to drop low and then back to high before anything would happen. This was done to sidestep as much of that noise as possible. Any variables used by the interrupt-service-routines are declared as a volatile byte. Data type byte was used for speed and data integrity.

Scalable solar-powered desal system could supply water to homes and towns

Scalable solar-powered desal system could supply water to homes and towns

Desalination makes saltwater more palatable and potable, but being a bit of an energy guzzler means it isn't the most practical solution in off-grid situations. A new system makes use of nanoparticles to harness the power of the sun and distill water more efficiently, without needing electricity.

Why Blockchain Is Good For Business, But Not Great For Consumers

Why Blockchain Is Good For Business, But Not Great For Consumers

Blockchain is rife with possibilities for organizations, if not consumers, but many remain unconvinced. Here's why.

There's been much ado about blockchain for years. But is the distributed ledger technology (DLT), which efficiently records and transparently shares contract and transaction data, worth the hype?

AMD launches broad Epyc server processor line with up to 32 cores per chip

Advanced Micro Devices is aiming for a comeback in servers with the launch today of its Epyc processors for the data center.

The AMD Epyc 7000 series is based on the company's groundbreaking Zen architecture, and the chips will have as many as 32 Zen cores each. The move represents AMD's most competitive attack on Intel's core Xeon server chip business in a decade.

When Innovation Moves Too Fast

When Innovation Moves Too Fast

We can adopt technologies early, but adaptation takes time.

Lag is the failure to adapt to changes in our engineered world. Lag is everyone's problem. Many people fall behind; most perpetually feel they will never catch up.

The problem isn't new. In the 1920s, the sociologist William Ogburn crafted an entire theory around the idea that social and cognitive traits make people slow to adapt to emerging technologies--and thus delay gaining their benefits.
