Givit Video Editor App Review

2 Replies Christopher Roberts

This is the 200th article I have written on Technology Bloggers! I really enjoy writing for the blog and value the community. :-)

Technology Bloggers top smartphone app reviewers are without a doubt, Steve and Ron. In the past I have attempted app reviews myself, however I have never reviewed just a single application in one post. What better time to try something new then than in post 200!

I’m playing it safe with my first app review, and choosing an app that has already been reviewed by TechCrunch, and written about on the The Wall Street Journal’s website. The app is called Givit Video Editor, and is available for all iDevices.

What is Givit?

So what exactly is Givit Video Editor? Well in the words of (the apps creators) Vmix Media:

“Givit is a free, fun and simple app to quickly make and share great videos on iPhone.”

As I am sure you know, Instagram is a photo sharing application, which lets you share photos you take, pretty much instantly, to Facebook, Twitter and Tumblr. Givit offers a similar service, but for video.

Sharing

One of the key features of the app is its sociability. The app interoperates ‘one-click’ sharing to Facebook, Twitter and YouTube, as well as email compatibility, so you can privately email clips. You can also upload your videos to the Givit cloud, where you get 5GB of free storage.

The latest version of the app (3.2.0) enables you to find and invite your Facebook friends, so you can see which of them are sharing their videos, and post your clips to your stream.

Features

The app is a clever video editor, which lets you mash different clips together, so you can chip and chop the best bits of clips and the stitch them together to make great montages.

The app is also compatible with live editing, so you can modify clips as you are filming, adding effects and music wherever you choose.

Cost

One of the best things about the app is that it is completely free! With the Standard Account (as I mentioned earlier) you get 5GB of permanent free storage; so long as you use it once every 3 months. 5GB is enough room to store around 30 minutes of uncompressed HD video; Givit probably have some clever compression going on, so I would imagine you get a bit more that 30 minutes.

Half an hour is all I think I need, as the clips I want to share are only usually a minute or two long, however if you are a budding videographer and need more space you can buy a Premium Account, which costs $29.99 a year, for an extra 100GB of storage.

So far, reviews of the app seem positive. The apps official iTunes rating is currently 4 stars in the UK store and 3.5 in the US store. Coverage on sites like Macworld, CNET and the above mentioned TechCrunch indicate the growing popularity of the service.

Shoot, edit, share and store – that’s Givit!

Vintage Computers For Sale

2 Replies Jonny Hankins

Buoyed by the sale of one of the first and few remaining Apple 1 computers for $650,000 I started thinking about the old machines that were lying in my mum’s garage and wondering if I was sitting on a fortune.

Although I myself was never interested in computers my younger brother was a guru, going on to study computing at University, so we have a real vintage lot just awaiting discovery.

The first Hankins computer was a 1981 Sinclair ZX81. What a machine that was. It was manufactured by the famous watch maker Timex in Scotland, and really represents the movement from mechanical to digital technology. I remember recording programs onto a cassette recorder that were broadcast over the radio as a series of sounds similar to the noise a fax makes. Then you play them into the machine and bang you are off, you could use your 1kB of memory to do almost anything (or nothing).

The keys were part of the machine, like an old cash register, and it is through these that my brother learned the skills of programming in Basic, although I never got to grips with it. Then he moved on to Extended Basic and machine code (whatever that is).

Anyway it will not make me rich, they go from about $2 to $20 on eBay.

But even 1 kB of memory was not enough for us so a couple of years later we (my parents) invested in what was in its day the height of technology, a TI99. This was altogether greatly improved, it had a cartridge system in the front so you could slide in games and use the cursors to maneuver through the asteroid fields.

The TI99 was manufactured by calculator maker Texas Instruments and was the first computer with a 16 bit processor. Texas Instruments were big on voice synthesis and the big use of it for us was during the game Parsec. With 16kB of memory we had moved on considerably, and my brother made the most of learning Extended Basic using their wonderful program.

Just look at the lines on this beast, a design classic it sold almost 3 million units and with 68 by 48 pixels in colour the picture was a joy to behold when plugged into our TV.

It was high finance though for our family, it cost more than $500 US when newly released but as with all of these things the price fell over the following years to $150, and so the question arises again, am I rich today?

The answer unfortunately is no, you can buy one on eBay for about $20. Could be a great investment though, they have one in a museum in Paris.

Well a couple of years passed and my brother needed a serious computer to take to University. At great expense my parents went for the BBC Microcomputer built by Acorn. This was much more of an educational tool, and its release was followed by a BBC educational series that taught its user (my brother and unfortunately not me) to program, and it was the machine of choice for UK universities and schools.

Our model B had 128 kB of memory, a giant leap that allowed graphics programing and increased complexity of use. It also had a floppy disc for ease of data transferral. It was a beast of a thing though as it sat in my brother’s bedroom, and it is the most expensive machine in the house to date.

Oh how I could pay my mum back if it were now worth the same as the first Apple I thought, but once more eBay broke the spell. From $10 to $150 with all the extra hard and software, so sorry mum the Austin Martin will have to wait.

After University (and post BBC) my brother went to work and we moved into company machinery, laptops, blueberry, blackberry, apples and other fruits of commerce, and I lost touch a bit, but I alone have owned 3 desktops and 3 laptops to date and it is all awaiting disposal, so there certainly isn’t much room in my mum’s garage today (certainly not enough for an Aston Martin anyway).

The size of the Internet – and the human brain

How many human brains would it take to store the Internet?

Last September I asked if the human brain were a hard drive how much data could it hold?

The human hard drive: the brainI concluded that approximately 300 exabytes (or 300 million terabytes) of data can be stored in the memory of the average person. Interesting stuff right?

Now I know how much computer data the human brain can potentially hold, I want to know how many people’s brains would be needed to store the Internet.

To do this I need to know how big the Internet is. That can’t be too hard to find out, right?

It sounds like a simple question, but it’s almost like asking how big is the Universe!

Eric Schmidt

In 2005, Executive chairman of Google, Eric Schmidt, famously wrote regarding the size of the Internet:

“A study that was done last year indicated roughly five million terabytes. How much is indexable, searchable today? Current estimate: about 170 terabytes.”

So in 2004, the Internet was estimated to be 5 exobytes (or 5,120,000,000,000,000,000 bytes).

The Journal Science

In early 2011, the journal Science calculated that the amount of data in the world in 2007 was equivalent to around 300 exabytes. That’s a lot of data, and most would have been stored in such a way that it was accessible via the Internet – whether publicly accessible or not.

So in 2007, the average memory capacity of just one person, could have stored all the virtual data in the world. Technology has some catching up to do. Mother Nature is walking all over it!

The Impossible Question

In 2013, the size of the Internet is unknown. Without mass global collaboration, I don’t think we will ever know how big it is. The problem is defining what is the Internet and what isn’t. Is a businesses intranet which is accessible from external locations (so an extranet) part of the Internet? Arguably yes, it is.

I could try and work out how many sites there are, and then times this by the average site size. However what’s the average size of a website? YouTube is petabytes in size, whilst my personal website is just kilobytes. How do you average that out?

Part of the graph of the internet

See the red circle? That is pointing at Technology Bloggers! Yes we are on the Internet map.

The Internet is now too big to try and quantify, so I can’t determine it’s size. My best chance is a rough estimate.

How Big Is The Internet?

What is the size of the Internet in 2013? Or to put it another way, how many bytes is the Internet? Well, if in 2004 Google had indexed around 170 terabytes of an estimated 500 million terabyte net, then it had indexed around 0.00000034% of the web at that time.

On Google’s how search works feature, the company boasts how their index is well over 100,000,000 gigabytes. That’s 100,000 terabytes or 100 petabytes. Assuming that Google is getting slightly better at finding and indexing things, and therefore has now indexed around 0.000001% of the web (meaning it’s indexed three times more of the web as a percentage than it had in 2004) then 0.000001% of the web would be 100 petabytes.

100 petabytes times 1,000,000 is equal to 100 zettabytes, meaning 1% of the net is equal to around 100 zettabytes. Times 100 zettabytes by 100 and you get 10 yottabytes, which is (by my calculations) equivalent to the size of the web.

So the Internet is 10 yottabytes! Or 10,000,000,000,000 (ten thousand billion) terabytes.

How Many People Would It Take Memorise The Internet?

If the web is equivalent to 10 yottabytes (or 10,000,000,000,000,000,000,000,000 bytes) and the memory capacity of a person is 0.0003 yottabytes, (0.3 zettabytes) then currently, in 2013, it would take around 33,333 people to store the Internet – in their heads.

A Human Internet

The population of earth is currently 7.09 billion. So if there was a human Internet, whereby all people on earth were connected, how much data could we all hold?

The calculation: 0.0003 yottabytes x 7,090,000,000 = 2,127,000 yottabytes.

A yottabyte is currently the biggest officially recognised unit of data, however the next step (which isn’t currently recognised) is a brontobyte. So if mankind was to max-out its memory, we could store 2,127 brontobytes of data.

I estimated the Internet would take up a tiny 0.00047% of humanities memory capacity.

The conclusion of my post on how much data the human brain can hold was that we won’t ever be able to technically match the amazing feats that nature has achieved. Have I changed my mind? Not really, no.
