This Helmet Knows When It's Too Damaged To Protect Your Head

Helmets made with a liner material called expanded polystyrene will protect your head during a ski accident, but need to replaced after the first major impact. Helmet liners made from expanded polypropylene, though, can endure multiple impacts before needing a replacement. Using a series of sensors inside its liner, POC's new Skull Orbic H.I. MIPS helmet can actually tell you when it's time to buy a new one.

You Can Now 3D Print a Model of Your New House

For most people, staring at blueprints is a real chore. Nobody really knows what all those little lines mean, and, wow, they're just so blue. Most importantly, however, blueprints make it hard for a layperson to comprehend what a space will actually be like in real life, which is a problem when you're building a house—or anything, for that matter.

drag2share: Archos' 6.4-inch smartphone puts the buttons on the back

Source: http://www.engadget.com/2014/03/11/archos-64-xenon-hands-on/

When we talk about smartphones with buttons on the back of the case, most people's thoughts turn toward the LG G2. But now the French electronics outfit Archos has decided to follow in LG's footsteps with the 64 Xenon, a 6.4-inch phablet that puts both the volume and power buttons on the rear side. Packing a 1,280 x 720 IPS LCD display, dual-SIM slots and HSPA+ radios, it's clear that this is designed to square up against the likes of the Galaxy Mega, but with a much lower price tag of 200 euros (around $275).

As soon as you get this device in your left hand, you'll notice that the power button is in a great position, right next to your index finger. The volume buttons, by contrast, are meant to be reached with your thumb, but the positioning felt a bit awkward to us -- it's hard to grip the device while applying any pressure to these buttons.

In the performance stakes, we were reasonably impressed by the responsiveness of the quad-core MediaTek MT6582, even though it's a whole generation behind the chip in Archos' other new smartphone. The processor is accompanied by 1GB of RAM and a 2,800mAh battery, which the company promises should last you for a day on a single charge.

On the downside, we were disappointed to see that the company cut a big corner with the internal storage: it's offering just 4GB as standard, which isn't right given how much stuff you're likely to put on this handset. On the other hand, at least there's a microSD slot for storing more content. Still, we're looking forward to putting this hardware through its paces when it launches in April.

drag2share: Hacker Claims This Crucial WhatsApp Flaw Can Expose Your Messages in Minutes

source: http://feedproxy.google.com/~r/businessinsider/~3/DYucUkMsGZw/crucial-whatsapp-security-issue-2014-3

WhatsApp users should be careful when downloading Android apps. If you don't read an app's permissions attentively before installing, your WhatsApp chat history could end up in a stranger's hands, according to one IT specialist from the Netherlands. 

Bas Bosschert, a technical consultant with more than 10 years experience working with Linux and Unix, explained how developers can trick WhatsApp users into granting access to their entire message database. Since WhatsApp backs up messages on your phone's SD card, apps can easily access this information if granted permission to do so. This data can then be uploaded to the developer's personal Web server. 

Bosschert's blog post details how to create these types of apps. The Netherlands-based technical consultant says that if the code shown in his screenshots was added to an Android game, it could be used to extract a WhatsApp user's database.

"People would only see a loading screen when they started the game," Bosschert said in an email to Business Insider. "They wouldn't notice that their WhatsApp database has been uploaded."

Security concerns surrounding WhatsApp aren't new, but have been attracting more attention since Facebook acquired the text messaging alternative last month

Mute Mic Prevents Your Phone's Microphone From Recording Audio

Android: Your phone is a hot bed of paranoia-inducing sensors. If you're worried about your microphone being used to record audio surreptitiously—or you'd like to do something simple like record a video without sound—Mute Mic can block other apps from using your mic.

The app is a one-button affair that mutes the microphone input volume system-wide. There are no settings or extra buttons to fiddle with. Just tap the button and you're done. This is particularly handy if you need to restrict the microphone permission on an app that you need, but that might be requesting too many permissions.

drag2share: Wall Street Is Going Crazy For A Revolutionary Technology That Could Change The Energy Market As We Know It (PLUG, BLDP, FCEL)

Source: http://www.businessinsider.com/fuel-cell-rally-2014-3

Screen Shot 2014 03 11 at 9.54.18 AM

Stocks of companies that develop and cell fuel cells are going crazy — their shares are about 50% in the past five days.

The gainers include:

  • Plug Power: 67%
  • Ballard: 48%
  • Fuel Cell: 49%

Among the catalysts for the surge was the announcement of a huge new Walmart order for Plug Power's fuel cells — which use Ballard materials; as well as a strong revenue report from Fuel Cell.

The market caps of these companies are tiny, but still, the surge cannot be ignored. Are we really on the verge of fuel cells going mainstream? 

Let's back up for a moment.

What are fuel cells? 

Basically, fuel cells take hydrogen and turn it into electricity. The most common way of doing this involves using a proton exchange membrane.

This is a membrane that separates out the positive and negative charges — the proton and electron — of a hydrogen atom. The membrane is treated in such a way that the electron cannot pass through it; instead, it only captures the proton. This allows the electron to go through an external circuit and get momentarily captured as electricity.

The exhaust product from the system is created by the proton and electron recombining with an oxygen molecule, which is flowing through the other side of the membrane. The only "waste" created from a fuel cell is water heat, meaning they are essentially carbon neutral.   

Via Ballard, Here's the visual demonstration. The flow field plate is charged to separate out the proton and electron.

how fuel cells work

Hydrogen and oxygen pass through along either side of the charged membrane. 

ballard fuel cell

The hydrogen atom gets split into its positive and negative charges — protons and electrons.

The proton passes through the membrane, where it will become part of an exhaust product...

While the electron gets temporarily captured as electricity.

The split proton and electron are reunited with an oxygen atom to produce water and heat — a nearly pure form of energy exhaust.

If you stack a bunch of these guys together, you get a fuel cell.

More demand, and getting cheaper

The long-term shift in the marketplace is that hydrogen — namely in the form of natural gas, which is simply hydrogen and carbon — is getting cheaper and more abundant, according to Bloomberg's Christopher Martin. On the higher end, solar-based fuel cells, which convert, converts solar and wind energy into hydrogen, have seen cost improvements as solar use has expanded. And fuel cells form part of the push toward cleaner energy, something Walmart has been pushing. And a recent note from Navigant notes more sectors are looking to fuel cells to provide grid-independent sources of power in case of natural disasters.

“With the growing need to enhance grid resiliency and the accelerating adoption of distributed generation technologies worldwide, the stationary fuel cell industry is well-positioned for growth over the next decade,” says Mackinnon Lawrence, research director with Navigant Research.  “Expected to break through the $2 billion mark in annual revenue in 2014, stationary fuel cells are seeing increased financing options for adoption, particularly in the healthy residential combined heat and power segment.”

Walmart also sees the cells as cost and labor-saving devices, since it takes less time to refuel a lift, and thus creates less downtime.  

The hype cycle

But again, the market cap of these firms remains relatively minuscule. As far as their use in transport, fuel cell use is so far limited to light industrial machines like forklifts. Navigant says the stationary fuel cell market will reach $9 billion in annual revenue by 2022.

 

More importantly, these stocks have come under huge waves of hype before when he market gets frothy.  Plug Power went public during the dot-com bubble, and while it survived, its stock has gone nowhere for the past decade. Check out the insane heights it reached during the bubble.

 

plug power

Some analysts believe everything will ride on whether automakers ultimately start rolling out fuel cell vehicles en masse. But given the surge in demand for electric vehicles, there is a decent chance the bump doesn't go much higher from here.

drag2share: Another major game engine gets Linux support ahead of Steam Machines launch

Source: http://www.engadget.com/2014/03/11/cryengine-linux/

The engine that powers the Crysis series, CryEngine, is headed to Linux. That means games like Crysis 3 and Ryse: Son of Rome could see ports on Valve's forthcoming Linux-powered platform, SteamOS. At very least, it means that developers already working with CryEngine have a shortcut to porting their work to Steam Machines; Crytek will show it off in detail next week at the annual Game Developers Conference in San Francisco. Linux support was long-rumored for CryEngine, with job listings as far back as last July hinting that it was coming. It's unclear when the engine will get updated to support the new platform, but we expect it'll be long before Valve's Steam Machines initiative gets seriously underway.

drag2share: Archos' octa-core smartphone is surprisingly quick for the price

Source: http://www.engadget.com/2014/03/11/archos-50c-oxygen-hands-on/

When it comes to smartphones, hugs and all-you-can-eat buffets, more is better, right? That's why we had to sit down and play with Archos' 50c Oxygen. The gassy, Jelly Bean-running handset is one of the first to use MediaTek's 1.7GHz octa-core MT6592 CPU, housed behind a 5-inch 1,280 x 720 IPS LCD display. Archos has found room for dual-SIM slots, 1GB RAM, 8GB of on-board storage and a microSD card slot, while the 2,000mAh battery should last you at least a day.

Aside from the thinness of the device, some of the design cues, like the light-up strip for the menu buttons, reminded us a little of Sony's old Xperia handsets, which we always had a soft spot for. Being a budget device, alas, there's no LTE modem, and instead users will be forced to suck down data on HSPA+. Of course, the star here is the CPU, and while we weren't able to put this device through the normal barrage of benchmarks that we use in our reviews, a casual run-through revealed that it was a lot more responsive than other devices that we've seen at this price. The 50c Oxygen will launch in April, around the same time as its phablet-sized brother, priced at €230 ($320).

drag2share: SEO best practice tips for WordPress

Source: https://econsultancy.com/blog/64485-seo-best-practice-tips-for-wordpress

What is SEO?

Very simply, it’s an umbrella term for all the methods, tactics and processes by which you can increase the likelihood of your website appearing, and possibly ranking highly in the organic (non-paid for) search engine results pages (SERPs).

There are black-hat (bad) and white-hat (good) practices, and it’s easy to think of SEO as a manipulative exercise in artificially raising the profile of your site.

In actual fact, good SEO requires a level of attention to detail that will only improve the functionality and usability of your website. If it’s easy to access, navigate and search around then it’ll be all the more appealing to your visitors. 

Appearing higher in the SERPs is a positive by-product of this ‘best practice’ and the benefits to you will be even higher levels of traffic.

Don’t think that because you’re ‘just running a blog’ that traffic from higher SERP rankings is a fanciful notion. 

With a regular routine of link-building within the site, optimising headlines, permalinks and images, and writing relevant content, it didn’t take long for my music review blog to appear in the first couple of SERPs under certain search terms, and my chosen subject is quite a highly competitive area.

There are some bad practices too, such as artificial link-building and keyword stuffing, just bear in mind that Google is quite good at catching you in the act, and is not only quick but severe in its punishment.

As with the previous posts in this series, I am writing this for the benefit of a WordPress.com user. 

If you’re a WordPress.org user there are some great plug-ins available in the dashboard that will automatically assist your SEO. However in WordPress.com there are no plug-ins, but a lot of the work is done for you automatically in the backend. 

That doesn’t mean that ALL your work is done for you though.

Let’s take a look at some best practice tips for SEO.

Content

Yeah that old cliché. 

If you’re not producing good, relevant, entertaining, helpful content at a regular rate, then all of the added SEO tricks won’t help you one little bit.

How does Google know whether you’re producing good, relevant, entertaining, helpful content? It just does, okay.

Well actually it’s a complicated and ever-changing algorithim that’s impossible to second-guess or predict. All you can guarantee is that no matter what Google and the other search engines are also looking for in terms of ‘site health’, the value of your content will always be the top priority.

Good quality content gets recognition. That recognition will come in repeat traffic, social shares and links within other websites. This will drive traffic to your site and improve your chances of being found not just within organic listings but also through social media and peer recommendations.

The most important point here is this: write for human readers not search engines

If your content reads like a robot wrote it, nobody will stick around on your site, nobody will revisit and nobody will share it. Search engines will see this lack of interest and high bounce rate and rank you in the toilet-end of SERPS accordingly.

Regularity

Producing content, regularly and as often as you can is also a must for appearing in the SERPs. When it comes to my own blog, I have a policy of publishing at least one article a day during the week. I take the weekend off. As should you.

Blogging is a time-consuming art but does benefit from taking a day or two off to refresh the creative juices. Plus there are cats to feed and social circles to remind that you still exist.

Anyway, write as regularly as you can, and you’ll soon see that within a few months you’ll start to appear in SERPs and therefore pick up some organic traffic. If you don’t update regularly, search engines will view your site as irrelevant over time and rank you lower.

Length

Don’t be too concerned with the word-count. 

If you remember padding out university dissertations with overly rambling sentences just to achieve the 15,000 allotted word-count, do not worry about achieving a similar thing here.

Whether you’ve been recommended that a post should be at least 300 words long, or 500-1,000 words if your blog is new, try to resist padding it out with waffle. 

Be as concise as possible. A reader would rather read a shorter article that gets to the point then a long-winded epic.

That being said, if you’ve written a 1,000 word masterpiece stuffed with fascinating, completely relevant and helpful content, where you’ve been as tightly controlled and clear with your prose as possible, search engines will prefer this to one that’s half the length on the same subject.

The likelihood of you being penalized for writing a 290 word post instead of keeping to the often recommended 300 word optimal length is very low.

However if you’re struggling to fill a 300 word post, perhaps the subject you’re writing about isn’t quite suitable for you, or may require some more research.

Headlines

Keep them as concise as possible, although not to the point of making them too obscure or meaningless.

“A beginner’s guide to SEO best practice for new WordPress bloggers” is descriptive and accurate. However, to benefit your readers and because search engines tend to give keywords at the beginning of a headline the most attention it might be best to rework it.

“SEO best practice: a beginner’s guide” may be better as the most important words are at the front. ‘Beginner’s guide’ remains as it’s an accurate decription of the content, but then you also don’t want to limit your audience. 

I’ve excised ‘WordPress’ and ‘bloggers’ as these tips are universal in regards to most blogging platforms and content management systems. I’ve also removed ‘new’ as it duplicates the meaning of ‘beginner’s’.

It’s quite a dry headline though. It doesn’t feel very “Upworthy’ or ‘Buzzfeedy’. By all means try the technique of mixing SEO with more emotionally responsive language.

“10 electrifying SEO tips that will charge your blog with awesome”.

Hmm, I wish I hadn’t wasted that one in the body of this article now. 

Just realise that headlines like this are great for quick wins. A large amount of traffic may haul its way to your site in one big spike in the short term.

However, in order to be useful in the long term and strengthen your position in the SERPs, it’s best to create ‘evergreen’ content that sticks around forever that will always provide you with traffic.

Permalinks

These are the permanent URLs to your individual blog posts. This is the link that you’ll share when you wish to direct people towards that particular page.

You’ll notice that when you write a headline in the ‘Add New Post’ section of your dashboard, a permalink will be automatically created underneath it.

This will automatically copy exactly what’s written in the headline.

There are a couple of things you need to be mindful of here.

WordPress will automatically save what’s written in the headline field as soon as you click anywhere else on the screen, whether you’ve finished writing the headline or not. Also WordPress won’t automatically update the permalink if you change your mind on the headline.

Thankfully the permalink can be edited at any time. Just make sure you check it’s correct before clicking publish. 

It’s not necessarily best practice to copy exactly what’s in the headline directly to the permalink, even though this is done automatically. 

Google has stated that it’s best just to use three to four key words in your permalink, and that you should put the most important keywords first.

“10 electrifying SEO tips that will charge your blog with awesome” would benefit from a permalink that reads “SEO blog tips”.

It’s best to remove any numbers that form part of your headline from the permalink itself as these are considered valueless by search engines.

It’s also good to remove ‘stopwords’ such as ‘a’, ‘and’ and ‘the’.

Excerpt

This is known elsewhere as the ‘meta description’. This is normally generated automatically by WordPress, but it’s a good idea to craft your own manually.

wordpress excerpt

The excerpt or meta description is the snippet of descriptive text that appears beneath the URL in SERPs. 

snippet serps

And also when sharing the link on social media platforms such as Facebook.

facebook snippet

You want this to be less than 150 characters long, with your keywords as near to the front as possible, but still make sense as a readable sentence.

wordpress excerpt

Search engines will not raise you higher in the rankings because of the quality of the excerpt, but it will increase the likelihood that someone will click-through to your article based on how interesting, relevant or entertaining the excerpt is.

Images

An important part of SEO is how you name and tag your images. With accurate tagging, you will increase the likelihood of your post being found through image searches.

Simply uploading an image and leaving the complicated file name as it is just isn’t good enough.

wordpress image upload

You need to complete the Title, Alt Tags and Description fields when uploading an image for full optimisation.

The Title section provides the text that a visitor sees when they hover their mouse over the image.

Alt Tags are necessary because search engines can’t see your images, but they do read your tags. You want to add your keywords here.

The Description section is where you want to describe your image as accurately as possible. This helps the accessibility for those who are using ‘image reader’ software.

wordpress image upload

Categories and tags

Once you’ve finished writing your article, add it to a relevant category. Try to keep the category title as broad as possible.

tags categories wordpress

Then comb through the post to pick out all the relevant keywords to add to the Tags section. These should be more detailed than the category.

Much like the excerpt, tags don’t improve your chances of ranking higher in the SERPs. In fact if you overstuff your post with tags, whether they are related to the content or not, search engines may see this as manipulation and you may be penalised. Google and other search engines have stopped recognising keyword tags all together. 

Categories and tags however make it easier for your visitors to navigate your site, and therefore improve its usability, tying together relevant content.

Approach tagging with caution. Be short, relevant and sparing just to be on the safe side.

drag2share: Leaked ad explains why HTC's putting a 'Duo Camera' in its new One

Source: http://www.engadget.com/2014/03/11/htc-one-m8-telstra-leak-dual-cameras/

Ever since a leaked image showed off dual cameras on HTC's next One (aka the M8), the rumor mill has been trying to figure out what they're for, exactly. Now, an ad from Australian carrier Telstra leaked to GSM Arena appears to have removed any mystery. According to the copy, the "Duo Camera" will bring improved low-light capabilities and let you select the focus of a shot after it's been taken, in a similar way to the Lytro camera. You'll also be able to highlight significant areas of a shot, soften the background and add 3D effects. The phone is called the "All New HTC One (M8)," in the ad, likely to distinguish it from the last version. It also revealed a full HD 5-inch scratch-resistant screen, a step up from last year's 4.7-inch One, along with dual "BoomSound" speakers. Finally, it showed the latest Sense 6.0 version that'll let you double tap the screen to turn on the phone and swipe to access apps and social info. After all that, if there's anything left to learn, we'll find out in exactly two weeks.

drag2share: Here's When You're Depressed, Happy, And Hungover

Source: http://www.businessinsider.com/twitter-knows-when-youre-depressed-2014-3

You are what you tweet, Twitter data tells us.

Based the usage of different words and phrases in 2013 by day of the week and the month, analysts at Twitter have us all figured out. They can tell when we're happy, depressed, hungover, or even late for work.

Analysts shared their findings on the Twitter blog:

People are most likely to tweet ‘feeling sad’ on a Sunday in December or a Monday in October. Conversely, they are more likely to be ‘feeling happy’ on a Tuesday in December or a Tuesday in January — that was New Year’s Eve last year, which may explain it.

Running ‘late for work’? That is most common in mid-week in July and Fridays in January.

Sundays in March as well as Thursdays and Fridays in November are the days which see the most Tweets using the word "hangover."

Here are the visualizations:

Excuse the portrait mode video but this golf trick shot is so impressive that we can ignore the blatant disregard of proper cell phone video recording etiquette. Here's what goes down: the guy behind hits a golf ball to the guy in front who swings and hits the same ball without the ball ever touching the ground. It's like the golf equivalent of an alley oop dunk. Perfect timing, perfect execution, perfectly in sync.
