Fitbit lets bike-tracking loose

Published

on

Fitbit has announced an outdoor bike tracking feature for Fitbit Surge users, which allows them to monitor distance, duration, average speed as well as their heart rate and calories burnt.

Fitbit  has announced outdoor bike (road, mountain and BMX) tracking for Fitbit Surge users. Bike-tracking leverages GPS and other sensors on the device to allow riders to see distance, duration, average speed, heart rate, calories burned and the time; stats automatically sync wirelessly to the Fitbit app dashboard to review routes, speed and elevation in more detail. The Fitbit Surge now tracks all of these multi-sport activities and captures activity data in one place with easy to read historical charts and graphs.

Fitbit Surge offers the best of GPS, continuous wrist-based heart rate, all-day fitness tracking and smartwatch functionality in one device, with up to seven days of battery life. Multi-sport mode allow users to easily record running, cross training, cardio and now biking workouts – which automatically sync wirelessly to users’ accounts where they can easily view their exercise summaries.

  • Multiple Sport Mode – Track and view workout summaries for up to seven exercises that can be added to a device for easy tracking, including Bike (new), Run, Hike, Weights, Yoga, Bootcamp and more.
  • Superior Heart Rate Tracking Technology – Continuous, automatic wrist-based heart rate tracking with Fitbit’s PurePulse optical heart rate technology to motivate users to maintain workout intensity, more accurately track calorie-burn, as well as hit fat burn, cardio and peak intensity with simplified heart rate zones and track resting heart rate over time. All this is done without wearing an uncomfortable chest strap.
  • Industry-leading battery life – Up to 7 days of battery life (168 hours for heart rate, 5 hours GPS) to track everything from the work week, a full marathon or a rigorous mountain bike trek on one charge; Fitbit is working to deliver even longer GPS battery life.
  • Real-time comprehensive bike stats – Distance, duration, average speed, heart rate, and calories burned right on the wrist.
  • Bike exercise summaries on the app – Map preview of route, distance, duration, average speed, heart rate, calories burned, active minutes and ride impact on daily stats on the Fitbit app or web dashboard.
  • Additional bike stat details on web dashboard – Thorough map and graphs with a by-the-second view into speed, heart rate, heart rate zones and calorie burn for each ride; elevation profile gives insight into intensity of ride.
  • Bike exercise historical progress – Cyclists can challenge themselves to improve their stats by monitoring frequency, distance, duration, time in heart rate zones and calories burned for past rides.

Fitbit has also announced Multi-Tracker Support, which lets users seamlessly switch between Fitbit trackers throughout their day or week, so they can use the right tracker for any occasion. Users will now be able to pair up to six Fitbit trackers (one of each model) and MobileTrack (iOS only) to a single Fitbit account:

  • Once multiple trackers are paired to an account, Fitbit will automatically detect when a user switches from one tracker to another, with no buttons to push on the device or the app;
  • For users who want to wear a more discreet Fitbit One to work, or Fitbit Surge for a run, all of their steps will be seamlessly captured on their Fitbit dashboard;
  • Users with a compatible mobile device can also use MobileTrack as a tracker to fill in the gaps if they leave their tracker at home or forget to charge it

Availability
The Fitbit Surge is available from iStore and Dion Wired at a recommended retail price of R3 999. Fitbit Surge bike-tracking is now available to all Fitbit Surge users.

Money talks and electronic gaming evolves

Computer gaming has evolved dramatically in the last two years, as it follows the money, writes ARTHUR GOLDSTUCK in the second of a two-part series.

The clue that gaming has become big business in South Africa was delivered by a non-gaming brand. When Comic Con, an American popular culture convention that has become a mecca for comics enthusiasts, was hosted in South Arica for the first time last month, it used gaming as the major drawcard. More than 45 000 people attended.

The event and its attendance was expected to be a major dampener for the annual rAge gaming expo, which took place just weeks later. Instead, rAge saw only a marginal fall in visitor numbers. No less than 34 000 people descended on the Ticketpro Dome for the chaos of cosplay, LAN gaming, virtual reality, board gaming and new video games. 

It proved not only that there was room for more than one major gaming event, but also that a massive market exists for the sector in South Africa. And with a large market, one also found numerous gaming niches that either emerged afresh or will keep going over the years. One of these, LAN (for Local Area Network) gaming, which sees hordes of players camping out at the venue for three days to play each other on elaborate computer rigs, was back as strong as ever at rAge.

MWeb provided an 8Gbps line to the expo, to connect all these gamers, and recorded 120TB in downloads and 15Tb in uploads – a total that would have used up the entire country’s bandwidth a few years ago.

“LANs are supposed to be a thing of the past, yet we buck the trend each year,” says Michael James, senior project manager and owner of rAge. “It is more of a spectacle than a simple LAN, so I can understand.”

New phenomena, often associated with the flavour of the moment, also emerge every year.

“Fortnite is a good example this year of how we evolve,” says James. “It’s a crazy huge phenomenon and nobody was servicing the demand from a tournament point of view. So rAge and Xbox created a casual LAN tournament that anyone could enter and win a prize. I think the top 10 people got something each round.”

Blockchain unpacked

Blockchain is generally associated with Bitcoin and other cryptocurrencies, but these are just the tip of the iceberg, says ESET Southern Africa.

Published

on

This technology was originally conceived in 1991, when Stuart Haber and W. Scott Stornetta described their first work on a chain of cryptographically secured blocks, but only gained notoriety in 2008, when it became popular with the arrival of Bitcoin. It is currently gaining demand in other commercial applications and its annual growth is expected to reach 51% by 2022 in numerous markets, such as those of financial institutions and the Internet of Things (IoT), according to MarketWatch.

What is blockchain?

A blockchain is a unique, consensual record that is distributed over multiple network nodes. In the case of cryptocurrencies, think of it as the accounting ledger where each transaction is recorded.

A blockchain transaction is complex and can be difficult to understand if you delve into the inner details of how it works, but the basic idea is simple to follow.

Each block stores:

–           A number of valid records or transactions.
–           Information referring to that block.
–           A link to the previous block and next block through the hash of each block—a unique code that can be thought of as the block’s fingerprint.

Accordingly, each block has a specific and immovable place within the chain, since each block contains information from the hash of the previous block. The entire chain is stored in each network node that makes up the blockchain, so an exact copy of the chain is stored in all network participants.

As new records are created, they are first verified and validated by the network nodes and then added to a new block that is linked to the chain.

How is blockchain so secure?

Being a distributed technology in which each network node stores an exact copy of the chain, the availability of the information is guaranteed at all times. So if an attacker wanted to cause a denial-of-service attack, they would have to annul all network nodes since it only takes one node to be operative for the information to be available.

Besides that, since each record is consensual, and all nodes contain the same information, it is almost impossible to alter it, ensuring its integrity. If an attacker wanted to modify the information in a blockchain, they would have to modify the entire chain in at least 51% of the nodes.

In blockchain, data is distributed across all network nodes. With no central node, all participate equally, storing, and validating all information. It is a very powerful tool for transmitting and storing information in a reliable way; a decentralised model in which the information belongs to us, since we do not need a company to provide the service.

What else can blockchain be used for?

Essentially, blockchain can be used to store any type of information that must be kept intact and remain available in a secure, decentralised and cheaper way than through intermediaries. Moreover, since the information stored is encrypted, its confidentiality can be guaranteed, as only those who have the encryption key can access it.

Use of blockchain in healthcare

Health records could be consolidated and stored in blockchain, for instance. This would mean that the medical history of each patient would be safe and, at the same time, available to each doctor authorised, regardless of the health centre where the patient was treated. Even the pharmaceutical industry could use this technology to verify medicines and prevent counterfeiting.

Use of blockchain for documents

Blockchain would also be very useful for managing digital assets and documentation. Up to now, the problem with digital is that everything is easy to copy, but Blockchain allows you to record purchases, deeds, documents, or any other type of online asset without them being falsified.

Other blockchain uses

This technology could also revolutionise the Internet of Things  (IoT) market where the challenge lies in the millions of devices connected to the internet that must be managed by the supplier companies. In a few years’ time, the centralised model won’t be able to support so many devices, not to mention the fact that many of these are not secure enough. With blockchain, devices can communicate through the network directly, safely, and reliably with no need for intermediaries.

Blockchain allows you to verify, validate, track, and store all types of information, from digital certificates, democratic voting systems, logistics and messaging services, to intelligent contracts and, of course, money and financial transactions.

Without doubt, blockchain has turned the immutable and decentralized layer the internet has always dreamed about into a reality. This technology takes reliance out of the equation and replaces it with mathematical fact.
