Metacognitive

If I could choose just a handful of skills you must learn to be a successful engineer, being metacognitive would certainly be among them. What is metacognition? OOne of my favorite books on the virtue ethic applied to mental skills defines it thus—

Metacognitive people are concerned not just with what they need to know but with what thinking strategies are best suited to achieve that end. —Philip Dow, Virtuous Minds

The concept is simple. Implementation, as always, is the hard part. Particularly as engineers, we spend a lot of time thinking about technique. We ask questions like—

  • How do I configure this?
  • How would I use this technology?
  • What is the problem here?
  • Why would I want to do it that way?

These technos focused questions are great for solving day to day, or even no-so-day-to-day problems. But they aren’t so great for mental growth? Why not? Imagine you are tasked with cutting wood for a living. You might start out by simply cutting the wood. You place a piece on the block, swing the axe, and the splits fall off. You can consider this the what of cutting wood (or, for those who are interested in philosophy, the Continue reading

How open compute cuts server costs in the enterprise

The open compute project (OCP) means you can get the designs that Microsoft, Facebook and (to a lesser extent) Google use for their data centers.  The goal is to get original design manufacturers (ODMs) to build them for you rather than buying standard servers and switches from original equipment manufacturers (OEMs).To read this article in full or to leave a comment, please click here(Insider Story)

Facebook throws an open source hackathon

Facebook’s Boston-area outpost is in Cambridge, close to MIT – they’ve just expanded from a smaller site and annexed a whole floor of a well-kept office building near Kendall Square Station. The first thing you see when you get off the elevator is a floor-to-ceiling pattern of blue lines that are meant to spell out the words “Ship Love” (Facebook’s unofficial motto) in binary.It’s an airy, open-plan space, like many major tech company offices, with exposed concrete and pipes here and there, along with original art on the walls and the requisite amusements – in this case, a couple of Oculus Rifts, some musical instruments and a foosball table.+ALSO ON NETWORK WORLD: 6 Internet of Things companies to watch + Munich's great Linux desktop initiative may endTo read this article in full or to leave a comment, please click here

India blasts 104 satellites into orbit aboard one rocket

India’s space agency said today it had launched 104 satellites from a single rocket, crushing the previous record of 37 satellites from a single rocket by the Russian space agency in 2014.The rocket – India’s Polar Satellite Launch Vehicle (PSLV), also known as Cartosat-2 –is a four-stage rocket that India has used for a variety of missions since 1993. This was its 39th flight.+More on Network World: Small satellites bring “Moore’s Law” into space+To read this article in full or to leave a comment, please click here

This DARPA-backed Machine Learning program is a quick thinker

Gamalon is a Cambridge, MA-based startup that has received $7.7 million from DARPA to create an advanced machine learning and artificial intelligence platform that the company says is more time and computationally efficient than others on the market.Gamalon uses a new type of machine learning it has developed named Bayesian Program Synthesis, which the company says can accelerate machine learning by more than 100X. The basis of the BPS system is that it uses probability statistics to determine potential connections among the data. By doing so, it drastically reduces the amount of data that it needs to conduct artificial intelligence tasks, the company says.To read this article in full or to leave a comment, please click here

JavaScript-based ASLR bypass attack simplifies browser exploits

Researchers have devised a new attack that can bypass one of the main exploit mitigations in browsers: address space layout randomization (ASLR). The attack takes advantage of how modern processors cache memory and, because it doesn't rely on a software bug, fixing the problem is not easy.Researchers from the Systems and Network Security Group at Vrije Universiteit Amsterdam (VUSec) unveiled the attack, dubbed AnC, Wednesday after having coordinated its disclosure with processor, browser and OS vendors since October.ASLR is a feature present in all major operating systems. Applications, including browsers, take advantage of it to make the exploitation of memory corruption vulnerabilities like buffer overflows more difficult.To read this article in full or to leave a comment, please click here

RSA: Elite cryptographers scoff at idea that law enforcement can ‘overcome’ encryption

U.S. Attorney General Jeff Sessions’ call for a way to “overcome” cryptography met with scorn from a panel of elite cryptographers speaking at this week’s RSA Conference 2017 in San Francisco.“Any one of my students will be capable of writing good crypto code,” says Adi Shamir, the ‘S’ in RSA and a professor at the Weizmann Institute in Israel.Sessions’ use of the term “overcome” during his confirmation hearings actually means installing backdoors, says Ronald Rivest, the ‘R’ in RSA and a professor at MIT. He cited a joint Congressional study that concluded that weakening encryption works against the national interest, and that encryption is global anyway -- so the U.S. can’t call all the shots.To read this article in full or to leave a comment, please click here

IDG Contributor Network: Serverless computing — new idea or a new implementation of an old one?

My clients have started asking questions about a new industry catch phrase that they've started to hear coming from suppliers of cloud-based computing services. The phrase is "serverless" computing. They've also run into a related phrase, "Function as a Service." Is this really a new idea or a new implementation of an older one?In short, there is little new under the sun in the world of IT and this can be seen as yet another take at supporting a microservice in the context of a cloud computing service.To read this article in full or to leave a comment, please click here

NSS Labs rated 13 advanced endpoint security products, flagged 2 with caution rating

Advanced endpoint security products don’t do you much good if they can be evaded or eat your time by consistently throw false positives. Since enterprises are expected to defend against sophisticated threats and money in the security budget only goes so far, you might be interested in the results from NSS Labs’ testing of 13 security vendors AEP solutions. The results were released during the RSA conference.According to NSS Labs’ CEO Vikram Phatak, “The AEP test results provide vendor neutral insight and analysis to help enterprises accelerate their decision process and make informed decisions about when to deploy these products to manage their risk posture.”To read this article in full or to leave a comment, please click here

Researchers trick ‘CEO’ email scammer into giving up identity

Businesses targeted in email scams don’t always have to play the victim. They can actually fight back.Researchers at Dell SecureWorks have documented how they identified a suspected email scammer from Nigeria, by essentially playing along with the scheme to fool the attacker into revealing his true whereabouts.Anyone can use these tips, said Joe Stewart, director of malware research at SecureWorks. “We’re letting them (the scammers) give us all the information about themselves,” he said.The email scheme SecureWorks dealt with involved a fraudster impersonating a CEO in what’s called a business email spoofing attack. The goal is often to trick a victim into wiring funds to the scammer’s bank account.To read this article in full or to leave a comment, please click here
