Understanding iCloud

9 Replies victor

The latest release in the cloud computing world, and the replacement for Apple’s old MobileMe service is Apple iCloud. The new software is designed to work seamlessly between various apple hardware such as iPods, Apple laptops and desktops, and the iPad. There are several applications available with the iCloud software, ranging from ‘Find my Device’, which allows an internet connected device such as the iPhone to be remotely tracked, to Photo Stream, which makes ‘streamed’ photos available on any connected device.

The first, Find My Device, was initially a MobileMe application, which has been migrated to the iCloud software package. Using the service, a user can view the rough location of their device over-layed on a scalable map of the area, as well as a circle indicating the margin of error on the tracking. Along with remote tracking, the program also allows the user to change the password, display a message on the device, or play a sound (even if it is set to silent). A final feature of the program makes use of the cloud storage technology and allows the user to temporarily delete the contents of the device, storing them to the cloud server until told to return to their original location.

Computing from the cloud

Not quite cloud computing!

Photo Stream directly utilizes the cloud storage technology to share pictures between devices. When a picture is taken from an iphone with Photo Stream enabled, the picture will automatically be uploaded to the cloud server, where it will be available to any of the user’s other Photo Stream enabled machines. According to Apple, the service will soon be integrated with their Apple TV box, which would allow users to view any pictures in icloud on TVs connected to Apple TV.

While only currently available in the US, iTunes Match is one of the most popular uses for the virtual computing abilities of the iCloud software. iTunes Match allows users to ‘scan’ their music in any compatible device (even if the music is not purchased from iTunes), and upload it to the iCloud virtual servers, ready to be downloaded to any of the user’s other Apple products in a DRM free format.

‘Back To My Mac’ and iOS Backup are two more erstwhile MobileMe program migrated to the iCloud package. The first is essentially a remote access program, allowing the user to remotely log into any device with the same Apple ID and the program active. The second is a backup program, which allows the user to back up the data and settings on their device to the virtual servers, and restore the device or access the data remotely as needed.

While the iCloud software is very slim as far as system resources, it requires a fairly current OS to run properly. Creating an account requires iOS 5 or later, or for desktops, OSX Lion. For PCs, Windows Vista or later is required to properly sync. iCloud can also sync to Outlook 7 or later for calendars and contact info.

The cost of the iCloud software varies with the amount of services the user chooses to sign up for. Data storage starts at 5 gigabytes free, and added storage can be purchased in increments of ten gigabytes, for $20 per ten gigabytes per year. At the moment, the maximum storage amount available is 50 gigabytes, however Apple has said it is possible for that to go up in the future. Apart from storage costs, the iTunes Match service is a yearly fee of $25.

With the iCloud software, Apple has taken full advantage of the evolving cloud storage technology to bring a wide variety of programs to Apple users, and an increased connectivity between Apple hardware.

A few months ago, I wrote about LHC@home 2.0, which is a project that you can get involved in that allows you to use your spare computing capacity to help ‘crunch’ scientific data from the Large Hadron Collider project.

Rather shamefully, at the time of writing the article, I hadn’t actually taken part in the project, however after buying a new PC, I thought that it was my duty to donate my spare processing power to help science!


I started off by going to the SETI@home website, where I worked out that in order to take part in the search for extraterrestrial intelligence (SETI) project, I would need to download the ‘BOINC software’ – so I did. When I installed the software I was amazed with the amount of different projects that I was able to partake in.

The BOINC software is effectively a management tool which lets you choose which projects you want to help crunch data for. Then it sets about downloading, analysing and then uploading the data in the background.

The BIONIC LogoThere are so many great projects that people can get involved in, from looking for extraterrestrial life and the Higgs particle, to projects providing power to those who are doing vital research into malaria, cancers and other important global diseases, and even trying to work out how and why gravity works!

From finding new medicines to helping university students, there really is something for everyone to get involved in.

If you are worried that it may slow down your computer, then don’t be, you can set how much of your processor BIONIC can use, as well as the amount of hard disk space it can take up, and also how it uses your internet.

The BOINC software comes with an easy to follow interface, and gives you announces of important events and discoveries relating to @home projects.

The BOINC Manager Interface

Think where we would be in terms of scientific advancements, if everyone were to give just 10% of their PC to some of BOINC’s @home projects.

You can make a difference, and you can help science! Please go to the BOINC website to download the software today, and get stated with some of the brilliant projects they have on offer! I personally believe that the following projects are really worth a look at:

  • Poem@Home – investigating protein structures, how they determine protein function, how they interact with one another, etc.
  • LHC@home 1.0 – the Large Hadron Collider project – with some extra software, you can also take part in LHC@home 2.0
  • climateprediction.net – attempting to improve climate modelling, and predict the possible effects of climate change
  • Einstein@Home – searching through data from the LIGO detectors for evidence of continuous gravitational-wave sources, as well as searching radio telescope data from the Arecibo Observatory for radio pulsars
  • Cosmology@Home – comparing theoretical models of the universe in order to try to improve future technologies
  • malariacontrol.net – helping in the fight against malaria, via creating simulations and models of the history of Malaria
  • SETI@home – analysing data from outer space, to try and find extraterrestrial life

Unfortunately, I now have to give you a warning. Whilst I am sure that the software and projects are all 100% safe to participate in, some organisations would not want you to install them on their computers. You would be perfectly okay to install such projects on your home PC, however I wouldn’t advise that you do it at work or school, as there have been incidences in the past of firms pressing charges against people for increasing their internet usage and filling up there serves by unauthorised software like BOINC.

That aside, I really do urge you to download the BOINC manager today, any start helping science! If this makes the offer any more attractive, most projects have their own screensavers, many of which look pretty cool!

Install it and leave a comment below to let us know how you are getting on 🙂

Is paying for music a thing of the past?

With the availability of streaming music services like Pandora, Spotify, and Rdio all available for free and unlimited access, there are fewer people than ever actually paying for their music. According to a recent article on TechCrunch, Tom Conrad, the CTO of Pandora, said that about 50 percent of Americans don’t pay anything for music while another 40 percent only pay $15 a year for it.

If you were to walk into a big retail shop ten years ago, one of the biggest sections in the electronic media department would have been a massive collection of compact discs. Today with the likes of iPhone, and Android, CD’s have made technologies like compact discs seem old and obsolete technologies of the past.

The biggest culprit to the recording industry has been the proliferation of bit torrents and peer-to-peer piracy software. According to Torrent Freak, the Canadian Broadband Management Company says that forty percent of all internet traffic in North America comes from either Netflix or Bit Torrent. While the original intention of this sharing software was to make it easier for business to transfer important files, most of the traffic from it today comes from the illegal trade of music, television shows, and movies.

While services like Pandora, Spotify, and Rhapsody have a paid-premium option available, their free services are so convenient that there is no real reason to purchase them. Unless you want a completely advertising-free experience or simply want an unlimited data cap on what you can access per a week, the free versions of these programs work just as well and include almost all of the features. Ironically, the only companies that actually have to purchase these plans are the small retail stores that are selling you the music.

Spotify's LogoThe RIAA is having an abysmal time selling digital copies of singles and albums to consumers. Not only are the versions that are available online cheaper and make less money, they are also much easier to steal, copy, and distribute illegally over the internet. Google is partially to blame for this widespread availability of illegally traded music.

According to an article in the Daily Mail, if you type in your favourite artist into a Google search, several unauthorized and pirated versions of the song will show up available for stream or download. While Google is not implicitly to blame for this, they are turning a blind eye to the practice by ranking them higher in search results.

The person who is most responsible for the digitisation of music is the late Steve Jobs. When the iPod first appeared on the market, Steve spearheaded the movement to make iTunes the ultimate way to purchase music online. In an article in the Inquirer, David Hughes (head of technology at the RIAA) claimed that Steve was a hypocrite for claiming to be a spiritual leader but not putting enough piracy protection on digital downloads.

There is no turning back from the digital way of selling and listening to music. We have come too far in our technological advances and reverting to older methods such as CD’s and cassettes would seriously hamper our tech advances.

The music industry will need to find new ways to make income such as advertising, product placement, and incorporation in order to continue to make a profit… or it could just go away and make music an art form.
