Mobile Latency

Wednesday, April 23rd, 2014

Ilya Grigorik, developer Advocate at Google, has an interesting new post on his blog comparing the latency of WiFi and 4G networks. He concludes that WiFi can deliver low latency for the first hop in the network if the network is idle. 4G requires more coordination between the device and the radio tower but can […]

Mobile Evolving

Tuesday, April 22nd, 2014

Three articles over the last few days reminded me how mobile is still growing and changing.

Thursday, April 17th, 2014

I came across two things today that reminded me that Nokia lost many opportunities to be successful. The first is an article at digittoday that shows that Nokia had a production ready tablet ready as far back as 2001.

Android apps aren’t just implemented using Java. You can also compile and run c/c++ (NDK) code. This obviously runs faster but how much faster? With newer Dalvik implementations over time, how much faster is c/c++ now?
Learn OpenGL ES has a useful post that compares the speed of a digital signal processing (DSP) filter implemented in […]

Google Cloud Roadshow

Friday, April 11th, 2014

Yesterday afternoon I was at the Google Cloud Roadshow. It was mix of Google trying to sell their cloud services together with much deeper low level programming demos how to use the services, particularly on Android. If the Q&A at the end and my chatting with a few of the attendees are anything to go […]

Heartbleed and Mobile

Thursday, April 10th, 2014

I use a lot of online services and it’s interesting to see which ones haven’t been hit by the Heartbleed vulnerability. They tend to be the ones that have an extra layer of security. This includes those that encrypt data before sending via SSL and those where I have enabled two factor authentication.
