Data centers – where would we be without them?

1 Reply Christopher Roberts

It is hardly a controversial opinion to suggest that data centers are an indispensable part of modern life – it really is impossible to envisage a world without the vast capacity and power that data centers grant the business and information technology sectors – where would we all be without Google, eBay and Facebook? But what exactly are the advantages of a data center that their absence would remove? Let’s take a look…

Firstly, the cost to enterprises of running an in-house own data center is increasingly prohibitive, given the growing size requirements of such facilities. As more and more information is transmitted online and more transactions take place online – just as computing power continues to grow – then a data center needs exponentially more power and more hard disk space. Server racks just keep on getting longer and even keeping them cool enough becomes uneconomically costly for most small, medium or even large-sized enterprises.

Server RoomSecurity is the second big issue – in a world where cyber-crime and espionage is constantly growing, there needs to be a very robust response to security. Most enterprises just don’t have the time and resources to police their IT operations to the level required, and a good data center can give them the reassurances they need. Technicians can be on hand throughout the 24-hour cycle, not just to ensure that the server racks keep on functioning perfectly and that any problems are swiftly dealt with, but also to ensure that information is kept safe and secure and that hacking or phishing attempts are roundly thwarted.

So, where would we be without data centers? The answer is that we would have a vastly more limited cyber-world, with businesses forced to keep their computer operations artificially scaled back due to cost considerations, with the knock-on effect of a hobbled e-commerce sector. Social networks would be slow, unsafe and prone to disastrous infiltration, while search engines would also be grindingly slow and frustrating to use – welcome back to the late 1990s.

It’s safe to say that data centers are not only here to stay, but will keep getting bigger and better so long as the computer world leads the way.

How to share a mobile broadband connection

2 Replies Joe Linford

With the increase in mobile broadband technology, many people are increasingly turning to mobile dongles (like the ones here) at home instead of traditional connections, which cuts out the need for a fixed-line. However, with mobile broadband there are certain problems that can arise, the most obvious being that of sharing your internet connection with another device.

However, that needn’t be something that you become overly concerned with, as these days there are a variety of ways to share your mobile connection.

Most of the top providers are now offering technology to allow you to do this, such as 3 Mobile’s MiFi. With this you simply purchase the 3 MiFi and you’re away. It works pretty much the same way as a dongle, with one difference.

With a dongle you have to plug it into the machine, with MiFi you don’t, and can therefore connect to multiple devices at the same time. The devices themselves are small and easily portable; however, as is often the case with mobile broadband, internet speeds can be a little slower than hardwiring or even traditional Wi-Fi.

This doesn’t just mean you can connect to another Wi-Fi enabled laptops, games consoles or mobile devices, but also other Wi-Fi enabled devices including cameras, such as the Nikon Coolpix and the Kindle, so with MiFi and similar technologies, you can connect any combination of these, up to five devices. You can follow this link for more information on 3’s MiFi device.

A portable Wi-Fi router is another option for sharing the net. These are now relatively inexpensive and quite straightforward to use. You simply connect to a mobile network and share with other devices. However, do shop around before choosing one, as some are better than others.

Internet connection sharing is another option. By connecting a laptop or PC to the internet, you can then share its connection with other devices. For example if you’re running windows 7 this can be done through the network and Sharing Centre, but can be quite complicated  to carry out so is really only useful for advanced users or those who have the time and patience to hit the forums and get step by step instructions.

With different operating systems it works slightly differently so you may have to look up how to do this on yours too, this can be something of a headache.

If you have a 3G enabled phone, you can connect to the 3G broadband connection and then share with other devices. So as long as you have a signal, you can connect to your laptop or another device. However, download speeds are often reduced and quite often you can’t get unlimited data, so if you are sharing a connection you could quickly reach your limit.

The new iPad will allow you to do the same thing, however, despite the device being initially offered as 4G, this technology isn’t yet available in the UK. 4G uses the old terrestrial TV signal waves and widens the spectrum for mobile broadband.

However, Ofcom will be auctioning off the spectrum later in the year and this should be available in 2013 with the top mobile operators and will give even more options for mobile broadband.

Infix PDF Editor – Review

7 Replies Christopher Roberts

This is a sponsored review on behalf of Infix. To find out more about sponsored content on Technology Bloggers, please visit our Privacy Policy.

In this article I am going to review a piece of software by Iceni Technology, called Infix PDF Editor. The version I will be reviewing is Infix Professional for PC.

Infix PDF Editor is a program that enables you to edit and then save PDF documents. As Iceni put it:

“Infix Pro includes tools for handling graphics such as grouping, hiding and locking. It also adds the ability to edit and create clipping masks plus a vertical ruler to allow easier object alignment together with grids, guides and page margins.”

The quote mentions ‘Infix Pro’; this is because there are three different versions of the software. Form-Filler – a free version of the software which only lets you edit and reflow text. The ‘Standard‘ version of the software offers a lot more functionality, also allowing you to convert PDF files into other formats (ePub, RTF and HTML), add notes to the document, among other things. The ‘Professional‘ version lets you do even more, including joining multiple PDFs into one document, automatically renumber pages and adding/removing watermarks.

For full details of what the different versions offer, check out the table below which is from iceni.com.

Infix Version Comparison Table

The Form-Filler version of the software is free to download. The Standard version costs £59 and the Pro version £99.

So, that is the technical specifications of what the three different versions of the software offer, but, the real proof of the pudding is in the using – how easy the software is to use, and does it really work like it says it does.

The Interface

The interface is very easy to follow. It works in the same way that many programs do, so that you can find your way around it really easily, and you don’t have to spend a long time pondering what buttons do. I call this type of approach to software interface design KISS – Keep It Super Simple.

A KISS approach to interface design is, in my opinion the best. People don’t buy software for it to look good on their PC, they buy it because they want to increase their productivity, learning or enjoyment in some way.

As a result of the KISS approach, the interface does look a little basic. Basic is easy to understand, but not necessarily the most aesthetically pleasing.

In my opinion the functionality of software comes first, and aesthetics comes second. If you want software that looks okay and works well, then Infix fits the bill, however if you must have designer looking software, then you might be better looking elsewhere.

Below is a screenshot I have taken of the software.

Ease of Use

As I mentioned above, the design really aids the usability of the software. It is easy to find the function you want with the various optional toolbars, and the menu options.

Much of the software on your computer is probably not made by Microsoft, however you will probably notice that most software designers stick to the standardised layout. File, edit, view and help are standard on the top menu, below the top menu comes some optional toolbars, then the main content you are viewing, with a few options (often involving resizing and scrolling) at the bottom of the window.

There are some software producers who stray away from this tried and tested design. Sometimes it works, often it doesn’t. In Infix PDF Editor, the design conforms to the standard design, meaning that it is really easy to work out what is what.

Does It Work!

Iceni Technology LogoOkay, the software may be easy to use, affordably priced, etc. however if it doesn’t work, you aren’t going to want to buy it. I can inform you that it does work, and it works really well!

I have tried editing various different PDF documents with the software and it has surprised me every time with the functionality it offers. Like in Microsoft Word, you can ask the software to track changes, and put them in a different colour. This can be really handy if you want to show someone what you have edited.

You can also add notes when editing PDFs, sticky-notes, scribbles, text highlights and stamps are all available options, and as you would expect, when you save, you can view the edits with any PDF viewer. For more details, check out this handy screenshot and explanation on the Iceni site.

Not only does the software make it easy to edit PDFs, but it also makes is it easy to copy data from them. Sometimes, the way the PDF is constructed, if you try to copy some of the contents, say to quote it, when it goes into your document, it can often be a little mixed up. Infix makes it really easy to copy data from PDFs and transfer it to other locations.

The software also makes finding and replacing text really easy. Edit > Find and Replace > Replace > type in the word(s) you want to be changed and what you want the change to be to > click ‘replace’ and the software will chew its way through the document, changing any occurrences of the terms you asked it to. If you are tracking changes, you can then see the words that have been changed.

There are so many other things this software can do, it would take far too long for me to talk about them all. To mention a few you can: adjust paragraph indents, add header and footers, add new text, merge PDFs and renumber pages.

Help

Good software always needs to be backed up by good help and support. Iceni Technology don’t fall down in this area though, not with Infix at least. Their website hosts a series of screenshot guides and video tutorials which help you get to grips with all the different functions of the software.

They also have a support helpline and email address.

Compatibility

Infix is very diverse, and can be installed on a USB memory stick, Windows PC (2003, XP, Vista and 7) or a Mac (with MacOSX 10.5 or above).

For Windows 2003/XP you need at least 512MB of RAM (almost all PC’s do) or 1GB for Windows Vista/7, as well as a 1GHz x86 processor/CPU and 60MB free disk space – that should be no problem.

In terms of weight (power and space needed to run the software) I would say it is relatively light. I have some programs that require around 15GB of hard disk space, and a very capable graphics card, along with a large amount of system memory. Don’t get me wrong, still check your PC is up to the job, but I personally think most peoples will be.

Is Infix Value for Money?

Like I almost always say when I end a review, whether you think the product or service is value for money really depends upon what your use for it would be. If you occasionally use PDF documents and would like to be able to change them as a convenience, but don’t really need the software for any reason, I would suggest that it probably isn’t going to be that useful to you.

If however you are regularly dealing with PDFs, for whatever reason, be it part of your job, hobby or whatever, and would find it helpful to be able to make changes to them, then I think you would benefit from Infix software. Whether you go Standard or Pro is for you to decide, I think they are both reasonably priced for the services they provide, and the additional help that you get online.
