IDG Contributor Network: Stretchable screens will follow upcoming flexible ones

The smartphone in its current guise has been around for 10 years, and in that time it hasn’t changed form-factor much—a somewhat boring rectangular slab of plastic. Big deal.Ten years, however, are eons in tech life. Therefore one could ask just why haven’t smartphones morphed their shape in this decade of otherwise spectacular technological advancement? Have we really reached the pinnacle of communications tool design? More likely, a technical limitation.Samsung, though, is reportedly aiming to launch flexible devices soon, according to the Korea Herald. One of them is a “bendable Virtual Reality device with a flexible OLED display that can be bent to cover a user’s eyes completely,” for example, it says.To read this article in full or to leave a comment, please click here

Q&A: Migrating to Modern Data Center Infrastructure

One of my readers sent me a list of questions after watching some of my videos, starting with a generic one:

While working self within large corporations for a long time, I am asking myself how it will be possible to move from messy infrastructure we grew over the years to a modern architecture.

Usually by building a parallel infrastructure and eventually retiring the old one, otherwise you’ll end up with layers of kludges. Obviously, the old infrastructure will lurk around for years (I know people who use this approach and currently run three generations of infrastructure).

New Zealand High Court clears Kim Dotcom extradition to the US

Megaupload website founder Kim Dotcom and three associates were on Monday cleared by a court in New Zealand to be extradited to the U.S. where he faces a variety of charges including copyright infringement and racketeering.Holding that copyright infringement by digital online communication of copyright protected works to members of the public is not a criminal offense under New Zealand’s Copyright Act, the High Court found that a conspiracy to commit copyright infringement amounts to a bid to defraud, which is an extradition offense listed in the treaty between the U.S. and New Zealand.An earlier District Court judgment permitting the extradition was upheld by the High Court.To read this article in full or to leave a comment, please click here

F-bombing cop recorded threatening to sic dog on driver to rip him up

Getting pulled over by the cops can be stressful, especially if one of the cops is shouting, cursing and threatening to sic a 90-pound dog on a motorist to rip the *bleep* out of him. The Atlantic City cop was dropping f-bombs all over the place, doing so at least 10 times in a one-minute, 20-second video clip of the traffic stop incident which was posted on Facebook.I don’t see how you could help but be offended by the video. If not by the cop’s spewing of foul-language, then by the threats the officer made. It is unclear why the cops pulled over the young men, but one of the cops nuked out upon discovering the driver was using his phone to film them. One of the unidentified cops said, “Listen there’s two ways that this can go. Take that phone and stick it out of my face. I’m not gonna tell you again.”To read this article in full or to leave a comment, please click here

Python – Kirk Byers Course Week 3 Part 2

This post will describe the exercises and solutions for week three of Kirk Byers Python for Network Engineers.

Exercise two of week three we already completed in a previous post where we used a For loop to loop through the BGP output.

Let’s move on to exercise three instead:

III. You have the following 'show ip int brief' output.

Interface            IP-Address      OK?     Method      Status     Protocol

You don’t need printer security

So there's this tweet:



What it's probably refering to is this:


This is an obviously bad idea.

Well, not so "obvious", so some people have ask me to clarify the situation. After all, without "security", couldn't a printer just be added to a botnet of IoT devices?

The answer is this:
Fixing insecurity is almost always better than adding a layer of security.
Adding security is notoriously problematic, for three reasons

  1. Hackers are active attackers. When presented with a barrier in front of an insecurity, they'll often find ways around that barrier. It's a common problem with "web application firewalls", for example.
  2. The security software itself can become a source of vulnerabilities hackers can attack, which has happened frequently in anti-virus and intrusion prevention systems.
  3. Security features are usually snake-oil, sounding great on paper, with with no details, and no independent evaluation, provided to the public.

It's the last one that's most important. HP markets features, but there's no guarantee they work. In particular, similar features in Continue reading

Netool network port configuration analyzer – good concept, needs polish

When you get involved in the actual wiring of networks, one of the things you find yourself checking over and over is whether Ethernet ports are actually live along with do they connect to DHCP, is the Internet visible, and so on. Typically you’ll grab your laptop, plug it in and run a few tests but while this works, you might describe it as “sub-optimal” because how often have you tried to do exactly this in a ceiling void? In a cramped comms cupboard? Somewhere in the bowels of a rack? In every one of those situations it’s just time consuming and annoying to have to fiddle around and juggle with your laptop.
