Why you need waterproof electronics

Posted on the 17th May 2012 by

When I dropped my phone into the toilet I was amazed to see that it continued to work for a few seconds. All hope was quashed however 2 minutes later when it stopped, short, never to work again. I had only paid 26 dollars for it from ebay, but this was not the first time that such an incident had occurred in my household. My wife dropped her phone in the toilet on the day I bought it for her and I fell over whilst wading through a river in a drunken moment of foolhardiness and drowned my first mobile (and almost myself).

None of this need ever occur again however, thanks to nanotechnology. A company called Neverwet has designed an all purpose waterproof coating that can be sprayed on that repels water so well that they can even show a computer dipped into water while turned on still operates. Last year they won the Grand Prix Award as an innovative start up and their product is really quite impressive. Check out the video on their website.

The technology has many applications, it can be used to protect materials used under the sea to prevent corrosion, fabrics or small articles can be either dipped or sprayed, but the most interesting application certainly seems to be in electronics. A mother board can be sprayed and then used in wet conditions without failing. A great breakthrough I think.

If you are interested in weatherproofing you should know that there are already many all weather computers on the market. Terralogic sell a range of rugged computers and accessories for work and military purposes. Obviously if you are carrying a computer on a battlefield it cannot be a domestic lightweight and easily damageable machine, so these beasts are designed to be shock and water resistant, and they come in military green so you stand out from the crowd in your local Cyber cafe.

If you really need to go and work underwater you can purchase the WetPC, designed for the Australian military by Kord Defence Systems. This little baby is designed for underwater note taking, and offers a host of improvements over previous attempts making it much more user friendly through the adoption of its 5 key system. Combinations of the keys perform different functions making the machine suitable for underwater archeology, research and engineering as well as water sports.

If you want to go one step further how about the underwater cell phone? This little package allows you to make a receive calls as you dive, and works either at sea or in the lake or pool at the bottom of the garden.

Joking aside the technology is designed for commercial divers. The kit can be used with any phone that has a voice dialing system, as it sits within a face mask that is attached to a long lead with a floating buoy attached. The buoy hosts the broadcasting technology so that the user can connect to their normal service. All for about $1700 US. Take a look at the Ocean Reef company website for more details and to see what else tickles your fancy.

So just dip your HP into Neverwet for domestic use or go the whole hog with a military machine, the choice is yours, but in the days of rising sea levels it is always better to be prepared.

The journey of an email – as told by Google

Posted on the 16th May 2012 by

Today, when I opened up Google, I saw something new. In the past Google has used the space directly below the search box to notify users of holiday events, privacy policy updates, tributes to industry legends – such as the Steve Jobs tribute, among other things.

Today however Google is using this spot to advertise its new feature, which lets you follow the journey of an email: ‘The Story of Send’.

Google's homepage with a link to 'The Story of Send'

Google advertises 'The Story of Send: Follow an email on its journey.' on its homepage

When you click the link, you are taken to a page on Google’s Green website (.google.com/green) which tells you how you can

“Take a journey through Google’s data centers by following an email along its path.”

Click ‘Start the story’ and the journey begins! Google takes you through an interactive journey of a Gmail email, from when you hit send on your device, to when it arrives at its destination.

The tour takes about 5 minutes (around 50 if you watch all the videos) however, as we all know, the journey of a real email, takes seconds – if that sometimes.

It is evident that the project is meant to be promotional for Google, as it points out all the good points along the journey. For example, how they have ‘built an extensive Internet backbone across the U.S.‘ to speed things up; how they ‘protect your message with a wide range of security measures‘ and how their data centres use ‘50% less energy than typical data centers‘ etc.

What the journey fails to point out is the less desirable things that go on. One example being how your email is read (or spidered) by Google Bots/Spiders, keywords are picked out, and then relevant ads are displayed alongside the message. Another being how Google want not only to own the systems which deliver your emails, but also the infrastructure (the cables and power) which gets it there – is that not a bit of a monopoly?

I like Google, I think it does a wonderful job, and it is great that it offers us all so much for free, however they do also do a good job of covering up the stuff they don’t want us to here.

Check out the video below for more. I found it and tweeted about it a while ago, however never really found an article for it to go in.

So, have you taken the journey yet? Aside from the obvious PR (public relations not PageRank) stuffed in, it does make interesting viewing.

Why not talk about them both!

Good blogging practice – publishing reliable information

Posted on the 14th May 2012 by

The web is massive bank of data, which is far too big to be regulated. Because the web can’t be regulated, it is very easy for false information to spread – fast.

If you are a blogger, it is really important that you publish information which is reliable and trustworthy. Don’t copy what the crowd says unless you know they are right, as this is not only misleading to your readers, but can also see you get penalties dished out from search engines. If you get a reputation for publishing unreliable content, the likelyhood is that your readership will fall.

When you publish something that you have found out elsewhere, you need to make sure that it is accurate and reliable, before you publish it.

How to Mythbust Rumours

When you find information, on the web, in order to ensure that it is reliable, it is always a good idea to check that it appears elsewhere. A general rule of thumb is to check that what you are reading is the same on 3 other sites, one of which is a highly reputable site.

So what is a reputable website?

Government Websites

There are a few way so to identify if a site is reputable or not. One way is to see if it is a government website. Any site which is government run is likely to be very reputable. Government websites usually end in their own unique domain name extension. If you live in the USA, government sites end in .gov or .fed.us, in the UK .gov.uk, in France .gouv.fr, .gc.ca for Canada, India’s extension is .gov.in and the list goes on.

Major News Corporations

Government sites won’t always report things that you want to verify though, so there are other ways to tell a reputable sites. Big news websites like BBC.co.uk/News and Guardian.co.uk will usually only publish information that is factual and accurate, so you can usually trust them.

The Guardian's logoThe information they publish is likely to be accurate, however it may not be impartial, so that is something to watch out for. Often news firms will take a political side, and therefore report news in a certain way – and may only publish part of a story.

High PageRank Sites

Google PageRank is calculated largely by the number of backlinks a page or site has. If a website has a very high PageRank (6+) then it is likely that it has a lot of other sites linking to it, most probably because it publishes a lot of high quality content, which people find useful and therefore link back to. High PageRank sites aren’t always trustworthy, but the higher up the spectrum of PageRank you go, the less likely it is that a site is going to be providing false information.

If a website is a PageRank 8, 9 0r 10, unless they have manipulated Google’s algorithm (through black hat SEO, which will only work for a short while, before Google catches them) then the site is likely to be extremely reliable and reputable, therefore you should be able to trust the information, data and facts that they produce.

1,000,000 to 1

If 1 highly reputable site is saying one thing, but 1 million other (not reputable) sites are saying another another, then the chances are that the 1,000,000 sites are just recycling the same false information, creating a massive bank of false information. This is one reason why you should be really careful who you trust on the web, and also make sure that you verify information with at least one reputable site. Be careful who you trust.

Academic Research

Verifying information with at least 3 sources, one of which is reputable is something which is also advised in academic research. Therefore if you use the same standards on your blog, you can’t go wrong! Search engines and readers alike will respect you for providing good quality, highly reputable content.

Technology Bloggers Policy

Every time I write an article and quote information/statistics etc. I always try to follow the 3 and 1 rule: check the information appears on 3 other sites, at least one of which is ‘reputable’. This means that everything I write should be reputable.

The post guidelines ask all writers to ensure they use the 3 and 1 rule, however we cannot guarantee that all writers do. In our Privacy Policy, we state how we try to ensure all content is true and factual, however it is always advisable to independently verify information for yourself.

Do You Verify Your Content?

Do you always try to ensure that you use the 3 and 1 rule when publishing information? That not only applies to blog posts, but also to comments. If not what measures do you use, or don’t you think it really matters?
