Concerns about cell phone radiation

A new report by the Journal of the American Medical Association (download report) expresses concern that radiation emissions from modern smartphones and cell phones could pose a health risk.

The nonprofit organization The Environmental Working Group has a useful list of the radiation values (SAR) for most modern cellphones.

The NYTimes compiled some helpful advice (edited here for brevity):

  • Tilt the phone away from your ear when you are talking and only bring it in close to your ear when you listen
  • Wait until after your call has been connected to put your cellphone next to your ear
  • Cellphones emit less radiation when stationary because when you are moving rapidly — say, in a car — it must repeatedly issue little bursts of radiation to make connections with different towers as it moves in and out of range
  • If your cellphone has a weak signal it has to work harder and thus will emit more radiation
  • Texting, instead of talking, could be safer
  • Keep them at a distance by putting them on speaker mode or using a wired headset
  • The next best option is a wireless Bluetooth headset or earpiece, which emit radiation at lower levels.
  • Holding your phone away from your ear can make a big difference; the intensity of radiation diminishes quickly with distance.

Microwave News is a good source of techie phone information too.

Review of 5 Website Wireframe Tools

I recently decided to review our website wireframing/prototyping techniques to see where we could be more efficient in getting from concept to code. We currently use Dreamweaver’s Site tool and/or Fireworks or Illustrator for mockups.

The follow survey highlights some new wireframing and mockup tools. My main criteria was having the tool export the wireframe to html so that we could upload to our own servers for testing and client review.

Mockingbird

https://gomockingbird.com

Their description: Drag and drop UI elements to the page, then rearrange and resize. Go from idea to mockup in minutes. Link multiple mockups together and preview them interactively to get a feel for the flow of your application. Share a link and your clients and teammates can edit with you in real time. No more emailing images back and forth.

Price: $9/month Basic to $99/month Expert plans.

Cons: does not export to actual html for a true click-through web schematic.

Pidoco

https://pidoco.com

Their description: A GUI Design Software for clickable Wireframes. Fast and easy like Rapid Paper Prototyping, but completely web-based and with many more features. Advantages: Clickable Wireframes; Fast and easy Prototyping; Easy Remote Usability Testing; No Software Installation. Products & Features: Interface Prototyping; Prototype Reviewer; Remote Usability Tests; Realtime Collaboration.

Price: $9/month Personal to $85/month Unlimited plans.

Pros: has versioning. Online review tools with user commenting. Usability testing built in!

Cons: does not export to actual html to load a click-through web schematic to your own server or the client’s.

Denim

http://dub.washington.edu:2007/denim

Their description: An Informal Tool For Early Stage Web Site and UI Design.

Price:  free

Pros: standalone program for desktop PCs. Exports as HTML.

Cons: does not look to be current (last mod date 2008). Uses our own handwriting to make the mockups.

Pencil

http://pencil.evolus.vn/en-US/Home.aspx

Their description: The Pencil Project’s unique mission is to build a free and opensource tool for making diagrams and GUI prototyping that everyone can use. Top features:  * Built-in stencils for diagraming and prototyping * Multi-page document with background page * Inter-page linkings! * On-screen text editing with rich-text supports  * Exporting to HTML, PNG, Openoffice.org document, Word document and PDF. * Undo/redo supports * Installing user-defined stencils and templates * Standard drawing operations: aligning, z-ordering, scaling, rotating… * Cross-platforms * Adding external objects * Personal Collection * Clipart Browser * Object snapping * Sketchy Stencil

Price:  free

Pros: Firefox plugin and standalone program (via XULRunner, but not for Mac). Sketchy-like look and feel.  Exports site as HTML.

Cons: Unintuitive initial screens; hyperlink fields have no obvious URL field until a new “page” is created within the document. No site-wide export as HTML without arcane steps to install a so-called “template” of some kind. Not ready for prime time.

Wireframe Sketcher

http://wireframesketcher.com/features.html

Their description: WireframeSketcher is a software tool that helps you quickly create wireframes, mockups and prototypes for desktop, web and mobile applications. It comes both as a plugin for your Eclipse-based IDE and a standalone application. * Create wireframes and mockups * Get quality feedback fast * Build better software * All using your favorite Eclipse IDE * 45+ built-in UI controls * rough, unfinished, hand-drawn look for your mockups

Pros: standalone program and plug-in for many IDEs. Very cool sketch look. Nice toolset.

Cons: No HTML export. Complicated to begin; following the tutorial is essential.

Pentalobular screws and your iphone

A reader posed this challenge: did we know what “pentalobular” was without using a search engine. Latin tells us it’s a 5-sided something. If you have an iphone, then you have several pentalobular screws.

Turn to iFixit to work with these type of screws.

They have an iPhone 4 Liberation Kit for $10.

How Egypt’s government choked off the country’s internet access

New Hampshire network firm Renesys reveals their research (pdf) on how Egypt’s government choked off the country’s internet access via its state-owned data centers. Meanwhile, a Columbia law professor named Eben Moglen (of the Free Software Foundation) launches the FreedomBox Foundation, to ensure one day that people fighting for their freedom do not have their voices silenced by corporate/state-controlled businesses. The Plug computer was built to distribute the hardware infrastructure of the internet to everyone.

What is Foursquare, and should I care?

What is Foursquare?
Primarily a “location-based social networking service” for smartphones and mobile users. Users “check in” to places they’re at so that their friends know where they are. The most frequent visitor of a place (bar, restaurant, venue) can become the “mayor”, and users can also earn badges for completing special tasks.

The point of all this? The service posits that the world will really care about knowing the most popular, “hottest” places to be right now. Companies of course will hope their venue is just such a place and can advertise to the hordes.

One new service aggregates a group of services: http://socialgreat.com/

It gives a gestalt view from: Foursquare, Twitter, Brightkite, and graffitiGeo.

When your sales staff is compensated based on deal size, not profit

Interesting if not obvious-in-hindsight complaint about Sun Microsystems by Oracle head:

More infuriating, says Ellison, is that Sun routinely sold equipment at a loss because it was more focused on boosting revenue than generating profits. The sales staff was compensated based on deal size, not profit. So the commission on a $1 million sale that generated $500,000 in profit was the same as one that cost the company $100,000, he said. “The sales force could care less if they sold things that lost money because the commission was the same in either case,” he said.
