Quality vs quantity – the blogging dilemma

8 Replies Christopher Roberts

When I write, I want to write quality articles; articles which interest, amaze and inspire. Mediocre content annoy me. If ever I write something which I consider of low quality, I never publish it – I will either review it or scrap it.

A Wordle of blogging wordsI want to make a difference in the world, be it a small or big difference (I would prefer big) I have to start on a personal scale. If I can improve your life by changing the way you think and feel (for the better), and enriching your knowledge and understanding, then I am doing my job.

I love reading Jonny’s posts every week, they always interest me and many have inspired me to make (usually small) changes in my life and have often caused me to write something myself. Jonny posts once a week, on a Thursday – with the odd exception. Would he be able to post such great content if he posted twice a week? What about three times? I don’t know.

I am not meaning to pick on Jonny, once a week is just great and very appreciated. One day Jonny will stop writing as often, and one day he will stop writing all together. I hope that day is a long way off, and by that time I have no doubt that we will have other writers writing the quality and quantity of content that he writes.

The same goes for me. I get a lot from blogging at the moment, I love the researching and crafting process that goes into making an article, and I also love the responses. But one day I shall probably stop too.

Think about your favourite TV show, how often does it air? Usually (with exceptions) the best shows/series take months to produce and don’t launch every day/week of the year.

Blogging is the same. I want us to post 6 great articles a week. Jonny gives us one of those posts. I am usually able to provide another, and we often get the third from another writer – like Steve, Ron, Alan or another writer. Usually we only post 4 or 5 articles a week, and that’s fine. I would like to post 6, but would rather post 4 quality articles than 6 mediocre ones.

Blogs that post less often, usually don’t have such a great readership. It’s a fact. There are exceptions of course. What would a news site be, if it only published once a week?

If I was able to monetise Technology Bloggers so that I could run it as a business, then I could dedicate more time to it, as it would become a job, not just a hobby. Don’t get me wrong, sometimes we do host the odd bit of sponsored content, to help pay the hosting bills, and fund competitions, but this site is never going to make millions. I am not sure I would still want to blog, if it was solely for money though, so I don’t want to monetise the site.

So, here is the dilemma I have: produce okay content, daily; or produce quality content, less often.

I want to post 6 articles a week, only 3 are provided, who plugs the gap? Usually me. If I don’t I feel bad, as I don’t feel I have fulfilled my duty to the site. If I post the extra posts needed, but they aren’t quite as good as content I have produced before, I am angry that I let the posts go live.

There is a very fine balance which needs to be struck, and I am not sure I am there just yet.

Would you prefer to read 5 star articles once a week, 4 star articles twice a week, or 2 star articles daily?

The reason I am writing this is because I feel we had a great 2012, I had a great 2012 as a blogger, especially in the last few weeks. That said, I know my diary for 2013 is already looking pretty full. Friends, family, education, work and recreation all take a lot of our time, and rightly so. However other commitments I have, do mean that I will have less time to write in 2013.

Rest assured, I am not throwing in the towel and am going to continue to do my best to keep us up and running at full capacity, but there is a lot to do.

If you want to help, I am more than happy to accept suggestions. I would love to promote more users to author status, and give everyone more control.

3D printing – a revolution on the horizon?

18 Replies Christopher Roberts

What an achievement, this is my (Christopher Roberts’s) 100th post on Technology Bloggers!

Thank you everyone for your support, I love writing here, and that is because of the fantastic community we have created 🙂

3D printers have been around for around 20 years now, however it is only recently that they have really started to show their true potential, both in industrial and now even domestic settings.

Thanks to the recent advancements in 3D printing, CAD designs can be constructed into physical prototypes (and in some cases now even final products) by 3D printers. 3D printers have the potential to revolutionise the way we live our lives, due the variety of possibilities they unlock. 3D printing could revolutionise architecture, product design, industry, education, and so much more!

What exactly is 3D printing?

Most people have access to a normal printer, be it black and white or colour, ink jet or laser. Those sorts of printers however, only work in 2 dimensions, they can print content in the dimension that is left to right, and the dimension that is forward to back. 3D printing adds in another dimension, up and down. Therefore 3D printing means that you can print in height, length and breadth.

Why is 3D printing important?

Some critics have speculated that 3D printing will be as big, if not a bigger revolution to industry, and the way we live our lives, than the internet was. The internet has opened up so many opportunities, but it is believed that 3D printing, could possibly open up even more!

For architects, it will mean that within minutes, they will be able to print on screen prototypes of buildings, so they have a tangible product to show the customer, in virtually no time at all!

For retail, 3D printing could mean that shops hold no stock, and products (less complex ones at first, but branching out in the future) could be made to order, on site! No longer would shops be out of stock, so long as they have material to print on, they can make new products, there and then.

For healthcare, the new printing capabilities will mean that body part replacements can be accurately measured, designed, and then printed. Yeah, printed bones! Just last month, it was publicised that the first 3D printed jaw had transplanted onto the face of a woman from the Netherlands. The jaw was matched to the shape of the patient’s original jaw, using CAD modelling, and then layers of titanium powder were melted into shape by the powerful lasers that make up the 3D printer.

How do 3D printers work?

Different 3D printers work in different ways. Some work by building the object slowly, layer upon layer in an upwards direction, whilst others work by cutting down into a material. The titanium jaw example from above was built by building upwards creating layers upon layers of material, from titanium powder fused together by laser.

What materials can be ‘printed’ on?

Currently you can ‘print’ on plastics, metals, ceramics, glass, and even certain malleable foods (such as sugars and chocolate). In the future that selection of materials is likely to be expanded, and some even believe that we could grow human bone, and then 3D print replacements – that is still a way off at the moment though!

Could you get a 3D printer?

Many firms are looking to capitalise on the decreasing cost of 3D printers, so much so that some companies are now offering (simpler) domestic versions for home use!

One firm selling 3D printers to the domestic market is the New York company MakerBot. Makerbot are offering a basic 3D printer, which can create plasic objects using CAD software, for $1,749 (around £1,100).

MakerBot's 3D PrinterIn an interview with the BBC, MakerBot’s chief executive Bre Pettis, claimed that the printer is “a machine that makes you anything you need” which is “handy in an apocalypse or just handy for making shower curtain rings and bathtub plugs.”

Mr Pettis also said he hoped to get his printers “into the hands of the next generation because kids these days are going to have to learn digital design so they can solve the problems of tomorrow”.

Another company, (called 3D systems) is offering its ‘Cube’ 3D printers at a similar price to Makerbot, marketing it as a tool to express your creativity. The company is currently working on an app that will allow users to use the Microsoft’s Kinect motion sensor to create objects, simply by moving their hands through the air!

3D printing is bringing to the global market a fast and increasingly affordable way of turning ideas into reality. No longer will the joys of flexible design be limited to those with CAD jobs and the luxury of a prototype department. There is now a big incentive for people to learn CAD techniques and how to use CAD software. Many countries are now investing in 3D printing technologies, as they can see the potential; IT jobs in the UK and abroad are likely to see big benefits from this.

3D printing is real, and it is here.

So, what do you think about 3D printing, will it revolutionise the way we live our lives – even as much as the internet did? Or do you think that it is a waste of resources, and that it will never really be cost effective enough to be used on a mass scale?

Why does superfast broadband matter?

3 Replies Christopher Roberts

Technology Blogger has had many articles about broadband speeds, superfast internet connections, and how the general trend is that global internet speeds are on the rise, but the question is, why is that important? Why do superfast speeds matter?

Download and Upload

There are two types of internet speed, your download speed, and your upload speed. Your download speed is how fast you can receive data from the internet – how fast you can stream media, receive emails, load websites etc. Your upload speed refers to how fast you can send information to the internet – how fast you can send emails, upload media, update your status etc.

When people talk about broadband speeds on the rise, they are usually referring to download speeds, as most of us get a lot more from the internet than we upload. Both upload and download speeds are on the rise, but upload speeds are usually only around 10% of download speeds – depending upon your location.


So superfast broadband means that we can do things faster, we can download and upload content quicker than we used to be able to. But that does that mean?

More Going On

Faster internet speeds mean that you can be doing more things at once on the internet, with less lag or jitter. You can be on an online game, whilst streaming the radio, and in the background sending emails, all at the same time! You can have more internet hungry applications running at the same time, and the speed of your activities (providing you have adequate processing power) should be the same as if you just had one activity going on.

Improved Internet Call Quality

Faster internet speeds will allow for smother internet calling, with less lag and better quality. You will be able to chat with friend across the globe and stage a conversation as though they were there in the room with you. VoIP will be significantly improved, as faster speeds meant that the media you are sending out is of higher quality, and the stream you are receiving is better too.

Such improvements could significantly benefit businesses, as VoIP can significantly lower the cost of holding meetings with fellow colleges based in different locations, thanks to better, more affordable online conference calling.

Furthermore, improvements in internet call quality can make remote working more viable, meaning that employees can spend more time working and less time commuting, thanks to them being connected all the time. This can save time, money and office space, as more employees are able to work off-site.

Improvements in Healthcare and Education

As Rashed suggested in his recent article (Five changes in video conferencing for the next decade) improvements in internet calls could lead to an improvement in the provision of telemedicine, meaning that the best doctors can help patients from across the world.

There is also similar potential for education. The best lecturers and teachers will be able to educate far greater numbers of individuals from across the world, thanks to faster broadband speeds. Improvements in such technology could be very beneficial for those living in isolated communities.

Cloud Computing Becomes More Viable

Cloud computing has huge potential to cut costs, improve efficiency and improve data security, and superfast broadband makes it more viable! With faster broadband, more and bigger files can be stored in the cloud, meaning that files are less likely to be lost if one device fails, and are more likely to be accessible from any location.

Media Streaming

Streaming media from across the internet is smother, faster and more seamless with faster internet connections. You can watch online videos with less buffering, or even in high definition.

Furthermore, internet TV and other similar services become more viable than ever before. In the last quarter of 2011, Virgin Media reported profits of £48 million, which it is believed is mainly down to faster broadband speeds encouraging more users to user its TV and internet services.

More People Online

Every day thousands of new people around the world make the leap and go online. For every extra person on the internet demanding resources, the whole system slows down a little. However with superfast broadband, more people can be online with less of an effect on speeds. In large offices, more employees can be connected, with less of an effect on the speeds received. This is also true in households, more people can be downloading media, whilst it not affecting others on online games.

Your Speed

Superfast broadband is very important and is revolutionising the way we do business and live our lives. The question is, how fast is your broadband speed? Are you likely to benefit from the things I mentioned above, or do you need to think about switching provider? Try testing your broadband speed and comparing it to what you are paying for; could you be getting a better deal elsewhere?
