Why you need waterproof electronics

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.

Tips to improve your mobile SEO

Mobile search engines contain different algorithms and bots than used for traditional web searches. They evaluate websites as it is being rendered on a mobile phone. The ranks are computed based on how well the page is rendered for the phone that submits the queries. One thing you can do to improve your mobile SEO is to make verify the user agents, and the mobile crawlers can pick up your content.

Mobile phone search engines are not as finely tuned as traditional search engines. They are still placing tons of weight on bounce rates and using mobile visitors as barometers for how websites renders on phones.

One neat suggestion in improving your mobile search results is to follow traditional SEO strategies. Mobile indexes and bots determine different from web search. The differences entail things such as alt tags; heading tags and title tags are still dominant with mobile SEO.

After performing traditional SEO strategies, it proves necessary to create a secondary mobile sheet from your website. This will allow for formatting of existing pages to be viewed on mobile phones without having to create separate content. It gives you strength with the SEO value that you have already performed on your website minus creating new pages. You can use the mobile style sheet to assist in blocking things from being rendered with using a “display: none” on the style sheet. All mobile phones with the exception of iPhones can automatically pull the “handheld” style sheet.

iPhones determine different with not searching for mobile “handheld” style sheets. In addressing this critical problem, ensure that you copy your handheld sheet, and create on that is geared for the iPhone. The iPhone is meant to render entire website pages, and people statistically still prefer mobile-formatted content on their iPhones.

What Google search results look like on a smartphoneSometimes, mobile search engines will rank traditional pages but consider them ill-suited for rending on mobile phones even with mobile-specific style sheets. When this happens, the mobile search engine will rank the traditional content but “transcode” it for viewing on mobile phones.

Transcoded versions of websites are hosted on temporary subdomains on search engine’s domains. Typically, this provides a user experience that proves under-optimized. This is because navigation sometimes is broken or misplaced and the individual pages are separated into different pages for faster downloading. This can prove problematic when it comes to tracking activity on your mobile website, and if someone links to your content, the website might not receive credit for the links. Address this problem with a “no-transform”header of your content. The no-transform in the cache-control should stop transcoding.

Next, you should include a mobile-site map. Google provides tools that can help you in building one of these. For website owners using multiple-markup languages such as WML (Wireless Markup Language) or XHTML, you should submit separate mobile sitemaps per languages being used on the website. Ensure that you link to mobile site maps in your robots.txt file, the same as you would for traditional site maps.

When you are submitting a mobile site map, add the mobile style sheet and the no-transform tag for this should confirm fitting in getting the mobile search engines to rank your content.  Another excellent tip is to make sure your traditional content will work on mobile phones. This will provide the best chance of faring well with higher numbers of browsers and phones.

If your content on your website does not include external style sheets, or contains sloppy code or too many media files, the content will have problems rending on mobile phones. You might want to make mobile-specific content on a mobile sub-directory or sub-domain. This can generate tons of problems for SEO strategists because it can end-up splitting traffic and links between two sets of similar pages.

You should use a “handheld” style sheet with the no-transform designation. You can also re-arrange code so that it proves more suited for crawling and rendering. Redirection and browser-detection and self-selection are how websites and mobile phones interact with one another. Browser detection and re-direction is the process that appears to see what browser the website visitor is using to access your website. If the mobile browser is requesting the traditional website, a single PHP script can redirect the user to the mobile phone website. If a browser is requesting the mobile website, it can redirect them to the traditional website. This proves helpful if your website out-ranks your mobile website in mobile searches.

When you think of mobile SEO, the act alone proves dangerous to create a duplicate copy of your website and placing it in a sub-domain. Most website owners think that mobile phones are capable of interpreting the duplication, but unbelievably, they can become confused. When confusion occurs, your new mobile content has a very-little chance of outranking your traditional website in the mobile searches. Redirection and browser-detection should take care of these issues, but there is always a chance of duplicate content taking away value from the content located on the main website.

If this happens, you can try using a canonical tag that will promote the value from your mobile website back to your main website. You can then rely on your browser-detection and re-direction to take care of it. What proves dangerous in this scenario is that you might hurt your rankings for searches on the primitive mobile phones. The reason is that you are pushing the total SEO value into non-mobile content.
