Recently I have taken an interest in using digital means to recount history. The thing that has taken me most is the use of old photos that are either cut into or superimposed over new photos. The results really give an insight into the history of our modern urban landscape.
The Mail Online has a fantastic example of how photos from World War 2 can be superimposed upon photos of modern France, the effect really makes you think. This article has one of the original photos, the new photo and then one upon the other. So we see soldiers battling through the rubble of the town of Cherbourg in 1944, followed by the same shot taken today and then the two merged.
The obviously new addition of the cycle paths and modern signs in some way makes the photos even more dramatic, as it brings to life the reality of how we live today with the ghost of war ever present.
There are 11 fully merged photos to follow, and they all tell their own story.
Another site that offers a wealth of photos and an incredible history lesson is called Detroiturbex. The opening photo above is taken from their website. As we might imagine the project involves documenting the history of Detroit, and features photos of the city throughout its history, with a large section of connected, re-made and superimposed photos that recount the rise and fall of one of Americas largest industrial cities.
To give you an idea of what has happened to this great city in recent history, in 1950 it had almost 2 million inhabitants, but today only a third of that population remains. This means that more than 80,000 buildings lay derelict. The city has been declared bankrupt so there is no money to maintain any of the structures, and the results are there for all to see.
This is a big site, but a look at the index will guide you through a fantastic collection of photos, with the Now and Then section offering the matched and superimposed images. It is well worth a half hour to browse them all though, another reality of the American dream.
Flickr has a group called Looking into the Past that contains hundreds of images similar to those described above, which leads me to believe that it must be quite an easy thing to do. They certainly present an interesting historical perspective upon everyday modern life.
A quick search will find you plenty of others, including old postcards held over the original locations, very effective and absolutely DIY for those of us who like the analogue approach to life.
I was an English teacher for many years in Italy, and every year I played a game with the students. In groups we had an hour to invent an incredible product, prepare publicity for it and act it out to the class.
I had a can of Happiness and the logo “Happiness, now available in cans”. Many of the inventions revolved around making your school life easier though, including the intelligent pen that could for example write the correct answers in the test or translate from one language to another.
Well girls from Liceo Secco Suardo your dreams have come true. You in fact saw the future. Roll out the Smartpen.
The Learnstift Smartpen checks your spelling as you write. Incredible but true. Learnstift is a German Start up, and they are about to release their incredible product in English and German. It has 2 functions, one to help you write better that recognizes the form and shape of individual letters, and one that checks the spelling.
The pen has a tiny Linux computer inside that runs off a battery. It is fitted with a non optical motion sensor and a vibrating mechanism, so it can recognize the word you have written and if it is spelt wrong it will vibrate so you can try again.
It has wi-fi so you can connect to your phone or other hardware, and with a launch price of between $150 to $200 it is cheaper that paying me to come round to correct your homework.
Joking apart the producers hope the pen will become a valuable learning tool and of particular interest to dyslexic children. Although initially only in German and English as the project takes off more languages will be introduced.
Any of you who have learned a new language will understand how such a tool could be used in language learning and business communication, and as the pen can be made in ball point, fountain and even pencil versions I think there might be a fuchsia for it.
A couple of weeks ago I crossed Grand Island in New York State, a rather desolate place at this time of year near the border with Canada. I was interested in a virtual art installation involving augmented reality, and quite a find it was too.
It turns out that in In September 1825, Major Mordecai Noah founded a city state called Ararat on Grand Island, “a city of refuge for the Jews”. His idea was to create a Jewish homeland. Noah’s dream never came to fruition, until that is a group of academics and artists decided to create a virtual tour of how the city might look today had it been constructed.
The tour involves downloading an app into your smartphone, and travelling to specific areas on the island. When you look through the camera of the phone various structures appear in the view that are not present in reality. There is a copy of a memorial that was designed but has fallen into decay, a synagogue, school, a theme park and various other typical structures. The group also produced postcards, stamps and money, as well as other objects in everyday use in any nation state. There is in fact only one original artefact from that period surviving today, a cornerstone that tells the story of the city’s foundation.
People who would like to take the tour have to download the mobile app Layar, and aim their devices’ cameras at the landscape. The application uses geolocation software to superimpose virtual objects at precise GPS coordinates, enabling the public to see the objects integrated into the physical location as if they existed in the real world.
Then you just take the photo and the object appears as if in real life, with your friends next to it if you like. The Mapping Arrarat website explains everything, and hosts a short video that demonstrates the installation in practice. There are also lots of photos of the various structures that show people interacting with a virtual landscape.
Although the computer graphics aren’t entirely convincing I am sure they will very quickly improve and get to the point of looking absolutely real, very much in the way that games have developed in recent years. And an installation of this type looks like a fantastic educational tool to me. Objects can be placed on the landscape and presumably old photos and plans could be used to re-make places and events. Wouldn’t it be interesting to go the the Great fire of London, or walk through antique Rome and come back with a few shots to show the family?
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.
I 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.
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!
In 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?
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.
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.
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.
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?
