Review: Mio Alpha 2 heart rate watch

The scoop: Mio Alpha 2 heart rate training watch, by MIO, about $200 What is it? It’s not a smartwatch! It doesn’t measure your sleep! You can't draw doodles on its display! But if you want a better way to track your heart rate while working out, this watch will do this and more. A sensor on the back of the watch that touches your skin measures your continuous heart rate on your arm, giving you the information via its display or via a Bluetooth-connected device (works with iOS and Android devices) through its Mio Go app. Why it’s cool: The killer function of this is the continuous heart-rate measurement while the Alpha 2 is on your wrist, as opposed to having to wear an uncomfortable chest strap or, if you’re on a treadmill, using the handgrips. When working with the app, the watch becomes valuable in terms of letting you know whether you are working too hard or not working hard enough in order for you to get into the proper maximum training zone (for your age/gender, which is calculated through the app). To read this article in full or to leave a comment, please click here

The Upload: Your tech news briefing for Thursday, June 4

Prototype of HP’s Machine due next yearHewlett-Packard will have a prototype of its futuristic Machine computer ready for partners to develop software on by next year, though the finished product is still half a decade away. The single-rack prototype will have 2,500 CPU cores and an impressive 320TB of main memory. It will use current DRAM memory chips, not the advanced memristor technology that HP is still developing—one of the big reasons The Machine remains several years away.Samsung Pay coming to U.S., South Korea, then China and EuropeTo read this article in full or to leave a comment, please click here

Cisco ACI in the CNPES Cert (Engineering Specialist)

Cisco’s current network programmability certs uses two exams per cert, with the second exam focusing on ACI. That represents the first ACI-focused specialist exams from Cisco, and a great reason to learn about ACI and validate that knowledge. Today’s post looks at the ACI-focused exam for the Cisco CNPES Cert exam: the 600-512 NPENGACI exam. We’ll look at both the exam and a related video course.

Other posts in this series:

Overview

First, to set the stage, Cisco rolled out their network programmability (read: SDN) certifications over a period of months, mostly in 2014. Figure 1 shows these four certs, with the engineering specialist cert focusing on engineering and implementation.

Figure 1: Overview of Cisco SDN Certifications

 

Today’s post focuses on the second exam: the 600-512 NPENGACI exam. The name itself is a bit of a mouthful:

Network Programmability ENGineering with ACI

Basically, the NPENG 600-504 exam covers SDN implementation excluding ACI, NPENGACI 600-512 exam includes ACI.

iPhone laser dongle makes measuring a snap

iPhone dongles can do everything from high-speed data transfers to testing for HIV.At Computex 2015 in Taipei this week, a local manufacturer is showing off a laser pointer for the Apple phone that can precisely measure short distances.The iPin Laser Ruler is a thumbnail-sized dongle that fits in the iPhone’s audio jack. It houses a class 2 laser pointer that shines a dot of a light on a nearby object, such as a wall or piece of furniture. An app on the phone uses the camera to focus on the dot to determine the distance.To read this article in full or to leave a comment, please click here

Safety concerns have sparked lawsuits from regulators, its data collection practices have landed it in hot water, and CEO Travis Kalanick cant seem to shake his spoiled brat image.Hes aware of that. I can come off as a fierce advocate for Uber.

AWS customers want more information on its renewable energy plans

Amazon Web Services customers have sent a letter to the cloud services provider requesting that it disclose more information about its sustainability practices.The 19 companies, including Tumblr, Change.org and the Huffington Post, said they want to convey the information to their users, customers, employees and other stakeholders.While lauding Amazon’s commitment to get its entire cloud operation running on renewable energy, the companies wrote to AWS chief Andy Jassy last week that they want to see Amazon disclose more about its current carbon and energy footprint, its progress towards renewable energy goals, and its strategy for increasing its use of renewable energy. The letter also requests that Amazon share how it defines renewable energy and what energy sources the company will prefer going forward.To read this article in full or to leave a comment, please click here

The HP split by the numbers: 2,800 apps and 75,000 APIs

Hewlett-Packard has given a glimpse of what the company’s separation looks like from an internal IT perspective, and not surprisingly, there are some big numbers involved.The ongoing task involves dividing up or retooling 2,800 applications and 75,000 APIs (application programming interfaces) before the company becomes Hewlett-Packard Enterprise and HP Inc. on Nov. 1.Before the transformation began, HP had 50,000 servers in six data centers. Five thousand IT staff are working on the transition at any given time, said John Hinshaw, head of HP technology and operations, at the HP Discover conference Wednesday.HP has been preparing for the split since it was announced last October. The work is 80 percent complete, according to Hinshaw, and HP will actually start to operate as two companies on Aug. 1, he said.To read this article in full or to leave a comment, please click here

Enterprise IP Routing Best Practices

What motivated me to write this post is a state of the IP routing of some of the enterprise networks I’ve seen. A quick show ip route command reveals a non-disentanglable mixture of dynamic and static route with multiple points of redistribution and complex, rigid filtering rules, something you’d only see in your bad dream or a CCIE-level lab. It certainly takes a good engineer to understand how it works and even that can take up to several hours. I think the reason for that is that people have generally been concentrated on learning about the routing protocol, how it works, all the knobs you can twist to influence a routing decision logic. However, one thing often overlooked is the routing protocols best practice design, i.e. when and how to use a particular protocol. And since the latter is often an acquired skill, a lot of not-so-lucky engineers end up with wrong ideas and concepts in the heads. Below I’ll try to list what I{:.underline} consider a best practice design of today’s enterprise networks.
