Marco.org - Great since day one - 1 views

  • Apple tends to do that a lot. It’s deeply ingrained in their culture, priorities, and product development practices. In brief, their philosophy seems to be to ship only what’s great and leave out the rest. That’s why, instead of having a bad copy-and-paste implementation for the iPhone’s first two years, we just didn’t have one at all
  • Android as a platform, both in hardware and software, doesn’t reflect this. Nearly every hardware and software release has major shortcomings or rough edges. Many details and design decisions are lacking, wrong, or inexplicable. Neither Google nor the current Android device manufacturers embody the part of Apple’s culture that allows them to release a great product on day one. They have a different pattern: It’s always getting better. We’re always supposedly one or two releases from it being really great.
  • I never make technology-buying decisions based on future promises, rumors, or potential. I let other people be the bleeding-edge extremely early adopters, and I stick with what I know will work and stay out of my way. I don’t buy things that are “getting better”, because they usually don’t. Whatever caused them to be lacking in their current release will usually prevent them from being great in future releases. I buy things that are great today. They’re usually things that have been great since day one. And, more often than not, they’re Apple products.

How QR Codes Can Grow Your Business | Social Media Examiner - 1 views

  • Consumers want immediate access to what’s relevant and QR codes are being used to make that possible.
  • Bar codes are linear one-dimensional codes and can only hold up to 20 numerical digits, whereas QR codes are two-dimensional (2D) matrix barcodes that can hold thousands of alphanumeric characters of information. Their ability to hold more information and their ease of use makes them practical for small businesses.
  • When you scan or read a QR code with your iPhone, Android or other camera-enabled Smartphone, you can link to digital content on the web; activate a number of phone functions including email, IM and SMS; and connect the mobile device to a web browser.

  • There are other software companies that have created 2D codes that work much like QR codes, with Microsoft being the most notable.  Microsoft developed their own proprietary software to create codes known as MS tags.  Unlike QR codes, which can be read by a number of different readers, MS tags can only be read by the Microsoft Tag Reader.
  • Calls to Action – After building a community, the next logical step is to mobilize them to take action.   What are you trying to accomplish?  You can alternate special offers by simply linking your QR codes to new landing pages, and you can combine then with email opt-ins to build your list.
  • SEO and SMO – Earlier this month I wrote an article on social graphs where I discuss how web objects such as images, music clips, and videos add valuable content to your social graph.  QR codes enhance both your search engine and social media optimization.  Now you can increase traffic to those searchable objects to further optimize them by encouraging more sharing.
  • Social Proof – To help build a community offline, it can be helpful to use your vibrant online communities as social proof of your influence and expertise.  As one example, you can use QR codes to link to specific blog posts that have earned an abundance of activity.

XLP Energy Harvesting Dev Board | DigiKey - 0 views

  • XLP Energy Harvesting Development Board The XLP 16-bit Energy Harvesting Development Kit is a true development platform for realizing energy harvesting applications. The Microchip nanoWatt XLP PIC MCUs are ideal for these low power applications with sleep currents down to 20nA, active mode currents down to 50uA/MHz, code execution efficiency, and multiple wake-up sources. Powered only by light, the XLP kit enables rapid prototyping of low power applications such as RF sensors, temperature/environmental sensors, utility meters, remote controls, and security sensors to name just a few. For software development and programming, the kit includes the PICkit 3 programmer/debugger for use with the Microchip’s free MPLAB™ Integrated Development Environment.
  • UART to USB bridge for use in prototyping and PC communication
  • Solar Energy Harvester with EnerChip storage devices providing backup power
  • ...6 more annotations...
  • Individual disable jumpers for board components such as temperature sensors, LEDs, EEPROM, and potentiometer thereby removing unwanted standby current
  • Expansion PICtail connector with MCU controlled power supply
  • Prototyping area for adding additional sensors and circuits
  • PICkit 3 Programmer/Debugger and board level connector for application software development
  • PIC24F16KA102 eXtreme Low Power MCU with 20nA sleep currents(Can also be used with PIC24FJ64GA102)

Application does not show up in Android Market for Motorola XOOM tablet - Stack Overflow - 0 views

  • I had the same issue. Along with including android:xlargeScreens="true" I found this to be the fix.
  • The Android Market treats as though requesting a permission like CALL_PHONE also requests: <uses-feature android:name="android.hardware.telephony" /> The XOOM does not have telephony — the first Android Market-compliant device with that limitation. While it can have a data plan, it has no voice or SMS capability, and so it is treated as not having android.hardware.telephony. But, if you request permissions like CALL_PHONE, the Android Market by default will assume you need android.hardware.telephony. As a result, you will be filtered out of the Market for the XOOM. The solution is simple: for any hardware features that might be implied by permissions but that you do not absolutely need, manually add the appropriate element to your manifest with android:required="false": <uses-feature android:name="android.hardware.telephony" android:required="false" />
