Data and the stars

Published

on

An ambitious star-mapping project highlights the growing importance of big data and the cloud, writes ARTHUR GOLDSTUCK.

At an event in Berlin today, the European Space Agency (ESA) is unveiling the biggest set of data about the stars ever gathered. The positions and magnitudes of no less than 1.7 billion stars of our Milky Way galaxy have been gathered by the Gaia spacecraft, which took off in 2013 and began collecting data a year later.

The ship is also transmitting a vast range of additional data, with distances, motions and colours of more than 1.3 billion stars collected so far. And that is without counting temperature measures, solar system analysis and radiation sources from outside the galaxy.

“The extraordinary data collected by Gaia throughout its mission will be used to eventually build the most accurate three-dimensional map of the positions, motions, and chemical composition of stars in our Galaxy,” according to a project document. “By reconstructing the properties and past trajectories of all the stars probed by Gaia, astronomers will be able to delve deep into the history of our Galaxy’s formation and evolution.”

The entire project would be impossible were it not for advances in cloud computing storage,  big data analysis and artificial intelligence systems during this decade. The storage demands alone are mind-boggling. The ESA roped in cloud data services company NetApp, which focuses on management of applications and data across cloud and on-premise environments.

NetApp was previously involved with the Rosetta space mission, which landed a spacecraft on a comet in 2016. Lauched as far back as 2004, ten years later it became the first spacecraft to go into orbit around a comet, and its lander made the first successful landing on a comet.

“For the next two years Rosetta was following the comet and streaming data,” says Morne Bekker, NetApp South African country manager. “But with the comet speeding away from the sun at 120 000kph, Rosetta would soon lose solar power. Scientists seized the opportunity to attempt what no one had ever tried before — to gather unique observations through a controlled impact with the comet. Despite blistering speeds and countless unknowns, the spacecraft landed just 33m from its target point. 

“It’s quite phenomenal when you think of the data and analytics harvested, and the information it can send back. Now we’re helping with the Gaia project. You can imagine how much data is being collected daily. The catalogue will probably end up at 2 Petabytes in size – that’s 2-million gigabytes. If you think of the minute points of data being extracted, obviously you have to be using AI and machine learning to analyse all of this.”

Ruben Alvarez, IT manager at the ESA, sums it up simply: “Data is everything. Our biggest challenge is processing of the data.”

Naturally, ESA required absolute reliability from data storage. It also demanded almost infinite scalability to support the massive data requirements of past, present, and future missions. 

“We have a commitment to deliver data to different institutes in Europe on a daily basis,” says Alvarez. “Adding to the challenge, data from every mission must be accessible indefinitely. In the coming years, we will be launching new missions that will demand huge amounts of data. NetApp provided us with solutions that were scalable, even if we didn’t know in advance how much disk storage we were going to need.”

ESA says it expects to publish the full Gaia catalogue in 2020, making it available online to professional astronomers and the general public, with interactive, graphical interfaces.

The catalogue, says Alvarez, will unlock many mysteries of the stars.

“We call our site the Library of the Universe because we keep the science archive of
all of our scientific missions. This is how we allow people to really investigate the universe. t’s all about the data.” 

The mission has tremendous scientific implications, but also makes a powerful business case for big data and cloud computing.

“The capabilities for AI and machine learning in the processing of mass amounts of data are far-reaching,” says Bekker. “Not only does it equate to extreme performance, but also to massive non-disruptive scalability where scientists can scale to 20 PB and beyond, to support the largest of learning data sets. Importantly it also allows scientists to expand their data where needed.”

Across Africa, the power of the cloud and big data is only slowly being harnessed. A new research project, Cloud Africa 2018, conducted by World Wide Worx for global networking application company F5 Networks, shows that cloud uptake is now pervasive across Kenya, Nigeria and South Africa.

However, the research reveals that each country experiences the benefits of the cloud differently. Respondents in Nigeria and Kenya named Business efficiency and Scalability by far the most important benefit, with 80% and 75% respectively selecting it as an advantage. Only 61% of South African respondents cited it.

The opposite happened with the most important benefit among South Africans: Time-to-market or speed of deployment came in as the most prominent, at 68% of respondents. In contrast, only 48% of companies in Kenya and 28% in Nigeria named it as a key benefit.

This appears to be a function of the infrastructure challenges in developing information technology markets like Nigeria and Kenya, where the cloud is used to overcome the obstacles that get in the way of efficiency.

In South Africa, where construction of the giant Square Kilometre Array multi radio telescope is due to begin next year, the learnings of Rosetta and Gaia will ensure that data collection, storage and analysis will no longer be a challenge.

AppDate: Prepare for space

In this week’s AppDate, SEAN BACHER highlights Space Nation Navigator, Hitman Sniper, Snake Mask, Memrise, WhatsApp Web, and Carrot Weather.

Published

on

Space Nation Navigator

Space Nation Navigator is a bit of a strange app. It is part game, part exercise and part educational. On the game side, users have to navigate the Mars Rover, put the International Space Station back into orbit or move their Martians to safety before a sand storm hits Mars. When it comes to exercise, Space Nation Navigator provides users with a range of exercises and Yoga videos to prepare them for space travel and working in an anti-gravity environment. The education aspect teaches users about the planets, and star constellations, and then offers quizzes on what has been taught.

Platform: Android and iOS

Cost: A free download.

Stockists: Visit the store linked to your device.

 

Memrise

Memrise takes a new approach to help people learn new languages. Instead of providing a user with random phrases and words to memorise, the app connects you with a person already fluent in the language you want to learn. In turn, the person you are speaking to wants to learn the language in which you are fluent. Once your profile is filled out and languages selected, it connects you with people around the world who are interested in your language, and then allows you to chat with them in real-time. Memrise also lets one learn new languages through games, chatbots and grammarbots that help with spelling, tenses and pronunciations.

Platform: Android and iOS

Cost: A free download.

Stockists: Visit the store linked to your device.

 

Hitman Sniper

Hitman Sniper is loosely based on the Agent 47 movie released a few years ago. The game offers players the ability to hone their shooting skills through a range of training courses and, once they think they are ready, they can start taking out the bad guys. Things start off easy enough, but they get more and more difficult as one progresses through the 150 missions on offer. One will also have to upgrade various gun components, like scopes, magazine capacities and silencers, to make the missions a little easier. Hitman Sniper lets users buy 16 to tackle each of the missions – either with real money or via the points accumulated by completing missions. Money and points can also be used to upgrade firearms.

Platform: Android and iOS

Cost: R7 – with a range of in-app purchases.

Stockists: Visit the store linked to your device.

 

Snake Mask

The iconic Snake game that was preinstalled on most older Nokia phones has had a complete make-over. It now uses Facebook’s AR technology, meaning that you have to navigate the snake around obstacles in your home or office, all the while collecting coins and stars that change the snake’s speed and length. Unfortunately, Snake Mask is only available on Nokia’s new range of smartphones. However, it should not take long before it slithers onto other devices.

 

Platform: New Nokia smartphones running Android.

Cost: Free to use through the Facebook app installed on the device.

Stockists: Available through the Facebook app.

 

WhatsApp Web

Although this is by no means a new app, it is an extremely useful one, and one that not many people know about. Tapping out WhatsApps on your phone is easy enough, but thanks to WhatsApp Web it can be even easier. Open the WhatApp Web page under WhatsApp and you will see a QR code. Scan this code through WhatsApp on your mobile and you will be shown a replica of what you would normally see on your phone. You can then type and reply to messages using your computer instead of having to stop everything and unlock your phone every time a message comes through. WhatsApp Web is great if you share your computer with other people as it automatically disconnects when the browser is closed. However WhatsApp also offers an app that when installed will stay connected to your phone unless you manually remove it.

 

Platform: Any up-to-date Internet browser

Cost: Free to use and install

Stockists: Visit www.WhatsApp.com

 

Carrot Weather

There are thousands of weather apps on the Internet these days and all of them do the same thing – inform you of the weather in your area. However, Carrot Weather has taken what is just another app and turned it into something fun. By fun, I mean sarcastic, rude and completely politically incorrect. A user starts off by selecting religious and political views. It then asks about personality, ranging from friendly to homicidal to overkill – which includes profanity. So, for instance, instead of waking up to to the standard partly cloudy forecast, Carrot Weather will display something like: “It’s only partly sunny, the sun is a total effing failure.” It also has a range of insults that it throws at you whenever you open the app – some of them downright insulting, so it is definitely not for those who are easily offended. The app’s user interface is very simple, displaying a week’s daily forecast and hourly forecasts for the day selected.

Platform: Android and iOS

Cost: Free to download but with adverts. The premium, advert free version costs R12 per month.

Stockists: Visit the store linked to your device.

SA Start-up reinvents PABX

For any South African business, the idea of setting up or changing a telephonic switchboard system is the stuff of nightmares. Dealing with expensive hardware and hearing things like QSIG and VOIP is not what you’d call exciting.But now there is an app.

Published

on

Enter BuzzBox (www.buzzboxcloud.co.za), a web-based telephone switchboard that is aimed at small and medium sized businesses wanting to take the hassle and cost out of the company switchboard. Whether you are a small one-man operation or a larger organisation with staff working remotely, BuzzBox is the best switchboard solution.

What sets BuzzBox apart from anything else on the market is its easy-to-use dashboard. It puts you in control of everything from picking your phone number to setting up voice prompts and managing your business-hours schedule.

BuzzBox was developed when the startup behind it, Jini-Guru, needed such a service for its own use across multiple continents. “When we started Jini-Guru we could not find a seamless online process that would allow us to set up a full web-based switchboard, so we decided to build one for ourselves,” says Mike Smits, Director at Jini-Guru.

He says a lot of startups today are tech savvy and know how to use apps and the services that go with it. “It’s the uberisation of services and its driving demand for instant service activation.”

BuzzBox works as an app on both iOS and Android but users wanting a desk phone option can choose from a variety of devices on offer or use their existing VOIP phones.

Setting up a BuzzBox account takes 5 minutes. During registration your FICA documents are uploaded [ID and proof or residence] and you get to pick your phone number before the account is created. Companies that want to keep an existing number can do so too.

The real magic happens when you log on to the BuzzBox Dashboard. The main screen displays a summary of statistics for your account while the left-hand menu provides you quick access to various configuration settings and reports.

Setting up new extensions or external numbers is done with a few clicks and you can even set up various departments which is a great way to route a call to various people in a department, like sales or support.

The intuitive user interface also makes it easy to set up hold-music and voice prompts. You can add voice prompts by recording them straight to your phone, just make sure you use a clear voice with quiet surroundings for the best customer experience.

One of the main features of BuzzBox is its call recording feature that allows an organisation to record calls for legislative purposes, such as a lawyer, or for customer service purposes such as support. Recordings are stored securely online, and you have the ability to download recordings for playback. Companies can opt-in for this service and it’s free to use. Recordings are stored online and are fully encrypted so only you can listen to, or download them. Storage costs R1 for every 1000 minutes of stored recordings.

Other features include call forwarding and scheduling. The latter allows you to set office hours for your organisation which will divert calls to an after-hours messaging service. You also have the option to enable routing to an employee who is on call after hours.

BuzzBox also has a reseller program for companies wanting to offer this as a switchboard solution to their existing customers.

The costs for this service is R89 p/m for the first phone number which includes your first extension for free. Thereafter you’ll pay R89p/m per extension. Calls between extensions are free but you pay per second for all outgoing phone calls. More info on pricing can be found here: https://buzzboxcloud.co.za/pricing/

BuzzBox is offering a Launch promotion where they are offering the first line and extension free for 12 months. Only pay for calls. Use promo code “feoifyaa” during sign-up to apply your discount.
