Man who entombed Verizon worker gets probation, anger management

Because no one was physically injured or worse, headline writers such as yours truly felt able to characterize the August 2013 incident thusly: “Verizon worker thankful 911 operator could hear him now.” Today the 73-year-old Massachusetts man who perpetrated the criminal act against that Verizon worker must be equally thankful that a lenient judge has sentenced him to only a year of probation plus an apparently long-overdue anger management class.

IDG Contributor Network: Artificial intelligence will revolutionize Wi-Fi

Wi-Fi has moved from a nascent technology to one that is widely accepted and become so commonplace that we wonder how we ever functioned without it.It started from autonomous access points and was followed up by controller-based architecture (with a centralized controller and thin access points). And, as we learned from the challenges in deploying Wi-Fi and the ability of the environment to impact user experience, companies have constantly tried to innovate. Some focused on building dynamic channel or power planning, some built controller-less networks, and others tried to make it work in single channel. (Don't deploy single channel until you have read the challenges here.)To read this article in full or to leave a comment, please click here

Dangerous 7-Zip flaws put many other software products at risk

Two vulnerabilities recently patched in 7-Zip could put at risk of compromise many software products and devices that bundle the open-source file archiving library.The flaws, an out-of-bounds read vulnerability and a heap overflow, were discovered by researchers from Cisco's Talos security team. They were fixed in 7-Zip 16.00, released Tuesday.The 7-Zip software can pack and unpack files using a large number of archive formats, including its own 7z format, which is more efficient than ZIP. Its versatility and open-source nature make it an attractive library to include in other software projects that need to process and deal with archived files.To read this article in full or to leave a comment, please click here

Microservices Network Architecture 101

A new god is rising in the world of application development – Microservices

The new god promises if not happiness in the next life, scalability, agility and fault tolerance in this life. At the heart of all this, is a simple, age-old axiom that is a key design goal of Unix: do one thing, and do it well. In the evolution of application architectures, single monolithic applications made way for client-server applications, which in turn made the way for microservices. The upending of the old world continues in data centers.

Communication is at the heart of this new religion (one popular theory of the etymology of the word religion is the word “religio” which means “to reconnect”). Every religion and every new technology introduces its own new vocabulary.

Microservices are no different!

In the domain of communications, the new lingo involves things such as MacVlan, IPVlan, Weave, Flannel and Swarm, to just name a few. What are they ? How are they connected ? Is IPVlan a new encapsulation format ? If it’s not a new encapsulation format, what is it ? If it is a new encapsulation format, how is it related to VxLAN ? Why were they invented ? Which one should I use ? What Continue reading

Lawmakers probe large data breaches at US bank insurance agency

The personal banking information of about 160,000 U.S. residents walked out the door of the federal government's bank insurance agency on removable media of employees departing in recent months.During the last seven months, seven departing employees at the Federal Deposit Insurance Corporation (FDIC) have left with personal banking information on thumb drives and other removable media, agency officials told a congressional subcommittee Thursday.The FDIC, which provides deposit insurance to U.S. bank accounts, considered the data breaches as "inadvertent" copying of personal banking information that happened when departing employees were copying personal information to removable media, Lawrence Gross Jr., the FDIC's CIO, told the House of Representatives Science, Space, and Technology Committee's oversight subcommittee.To read this article in full or to leave a comment, please click here

Texting while driving messes with your six sense, Texas researchers say

Researchers from the University of Houston and the Texas A&M Transportation Institute (TTI) say drivers are more distracted when they text than when they are being absent minded or are upset while behind the wheel.The researchers, who based their findings on a study of 59 volunteers/drivers, say a mechanism in the brain automatically corrects for jitter in a driver's arms and hands while steering -- as long as the driver is watching the road. Reading or sending texts while driving takes the driver's eyes off the road, and that's where things becomes unsafe.MORE: Cellphone use involved in more than 1 in 4 crashes | 25 real-life ways people have been hurt using their phonesTo read this article in full or to leave a comment, please click here

Nest gives Thread IoT protocol group a new president and a new open-source implementation

Thread, an open wireless protocol for the Internet of things, is getting a boost from one of its biggest boosters, Google-owned Nest Labs. An IPv6 networking protocol built on the 802.15.4 mesh networking standard, Thread is designed to connect hundreds of low-power devices to one other and to the cloud. While the protocol is open, anyone wanting to build Thread-compatible devices had to roll their own software stack implementing it -- until now. Late Wednesday, Nest published the source code for its implementation of the Thread protocol, OpenThread, on Github under a three-clause BSD license, allowing anyone to reuse, modify or redistribute it in source or binary form.To read this article in full or to leave a comment, please click here

8 awesome (and sometimes free) conference call services

Conference calls are a big part of work life today — sometimes too big. Because we spend so much time in meetings, we want conference-calling systems that that launch quickly and work flawlessly so we can get the information we need and move on to other pressing matters. The capability to browse a post-meeting transcript or zoom through an audio recording would be big bonuses, especially for fastidious note-takers who don't always catch everything in real time.The good news is that the leading conference call services are full of features that take the sting out of group calls and online meetings. Standard features typically include audio recording capability, support for screen-sharing, automated transcripts (created by converting digital recordings into text), Web interfaces with hosting tools for managing calls and keeping track of participants, and 24/7 availability. Some services also offer personalized greetings to participants who dial in, customized hold music, operator assistance and a participant “dial-out” feature, where the service calls participants to bring them into the meeting (also referred to as "call me" functionality).To read this article in full or to leave a comment, please click here

Researchers reveal flaws in 7-Zip, users and security vendors affected

Cisco’s Talos researchers discovered two vulnerabilities in 7-Zip, the popular open-source file archiver known for having a high compression ratio and option to password protect compressed files.Even if users hurry to download the newest 16.0 version of 7-Zip, in which the vulnerabilities are reportedly fixed, that doesn’t take care of many products that have used the old 7-Zip libraries and are still vulnerable. Unless vendors do some work, they are vulnerable and users of their products are as well.To read this article in full or to leave a comment, please click here
