CCDE – A different Journey

Wednesday the 22nd of February, in a testing center in the middle of London, my journey towards achieving the CCDE certification, finally ended in me passing this beast of an exam.

This learning journey was a very different one than either of my CCIE’s. Whereas going for the CCIE meant spending countless hours at the command-line, the CCDE meant spending all of those hours reading and discussing use cases for technologies. It also meant stepping my toes into the business side, picking up the “Why?” behind selecting a specific technology.

It all started a few years ago when my friend Daniel (lostintransit.se) and I started going back and forth on how to approach this thing. We decided we should team up and share notes, discuss technologies and generally use each other as a sparring partner.

At that point I had already decided, that this was going to be a marathon for me, because I could at the time, not allocate as much time each day for study, as I had been for the CCIE’s. Fast forward a good amount of time and I had finally passed the written part of the exam and was ready to Continue reading

Pre-crime, algorithms, artificial intelligence, and ethics

I just binge-listened to an outstanding podcast, LifeAfter, which, without giving too much away, is about artificial intelligence and its impact on people. Here's the show's synopsis: When you die in the digital age, pieces of you live on forever. In your emails, your social media posts and uploads, in the texts and videos you’ve messaged, and for some – even in their secret online lives few even know about. But what if that digital existence took on a life of its own? Ross, a low level FBI employee, faces that very question as he starts spending his days online talking to his wife Charlie, who died 8 months ago…To read this article in full or to leave a comment, please click here

Apple is investigating an iPhone 7 Plus that ‘blew up’

A Twitter video of a smoking iPhone 7 Plus has gone viral, prompting Apple to investigate.On Friday, Apple said that it was working with Brianna Olivas, who shared the video of her iPhone 7 Plus after it “blew up,” to try to find out the cause of the explosion. Olivas wrote that her rose gold iPhone 7 Plus, which she purchased from Sprint in January, “caught fire” while she was sleeping on Wednesday morning.Her boyfriend moved the iPhone from the bed to the dresser before going to the bathroom. When he came back, the iPhone was “steaming” and making a “squealing noise” so he tossed it in the bathroom. That’s when the iPhone 7 Plus “blew up and more smoke started coming out.”To read this article in full or to leave a comment, please click here

Worth Reading: Bare metal cloud

When you think of the public cloud, the tendency is to focus on the big ones, like Amazon Web Services, Microsoft Azure, or Google Cloud Platform. They’re massive, dominating the public cloud skyline with huge datacenters filled with thousands of highly virtualized servers, not to mention virtualized storage and networking. Capacity is divvied up among corporate customers that are increasingly looking to run and store their workloads on someone else’s infrastructure, hardware that they don’t have to set up, deploy, manage or maintain themselves. —The Next Platform

I come to bury SHA1, not to praise it

Most cryptography is theoretical research. When it is no longer theoretical, in practice it can become a harmful exploit.Google and Dutch research institute CWI proved that the SHA1 hash method, first introduced 20 years ago, could produce a duplicate hash from different documents using a technique that consumed significant computational resources: 6,500 years of CPU computation to complete the attack first phase and 110 years of GPU computation to complete the second phase. The exercise was computationally intensive but proved it is within the realm of possibility, especially compared to a brute force attack that would require 12 million GPU compute years.To read this article in full or to leave a comment, please click here

Google discloses unpatched IE vulnerability after Patch Tuesday delay

Google's Project Zero team has disclosed a potential arbitrary code execution vulnerability in Internet Explorer because Microsoft has not acted within Google's 90-day disclosure deadline.This is the second flaw in Microsoft products made public by Google Project Zero since the Redmond giant decided to skip this month's Patch Tuesday and postpone its previously planned security fixes until March.Microsoft blamed the unprecedented decision to push back scheduled security updates by a month on a "last minute issue" that could have had an impact on customers, but the company hasn't clarified the nature of the problem.To read this article in full or to leave a comment, please click here

FCC puts the brakes on ISP privacy rules it just passed in October

The new chairman of the U.S. Federal Communications Commission will seek a stay on privacy rules for broadband providers that the agency just passed in October.FCC Chairman Ajit Pai will ask for either a full commission vote on the stay before parts of the rules take effect next Thursday or he will instruct FCC staff to delay part of the rules pending a commission vote, a spokesman said Friday.The rules, passed when the FCC had a Democratic majority, require broadband providers to receive opt-in customer permission to share sensitive personal information, including web-browsing history, geolocation, and financial details, with third parties. Without the stay, the opt-in requirements were scheduled to take effect next week.To read this article in full or to leave a comment, please click here

Cisco unveils Hierarchy of Needs for the digital enterprise

The European edition of Cisco Live took place this week in Berlin, which is a fitting location given the amount of innovation happening in that city right now. If you ever find yourself in Berlin, be sure to check out Cisco’s Open Berlin innovation center where inventive start-ups are building and showcasing solutions that run on Cisco technology. Innovation and digital transformation are linked together like Kirk and Spock. You can’t have one without the other. At this week’s event, Ruba Borno, Cisco vice president of growth initiatives and chief of staff for the office of the CEO, gave her first-ever keynote to a Cisco Live audience. Not surprisingly, she focused on digital transformation. However, unlike many keynotes I have seen, Borno didn’t just talk about digitization at a high level. Instead she was more prescriptive and gave the audience a guide on how to proceed with making the shift to a digital enterprise. To read this article in full or to leave a comment, please click here
