AppBooker, a purpose-built shop window for the world’s best mobile app developers, today opens its doors to a second round of registrations in the run up to its full launch later this month.
The aim of the site, which has already attracted over 300 pre-registered developers from 35 countries, is to deliver quality leads to its members.
Visitors to AppBooker will enter their specific search criteria – for example location, platform, specialisms and budget range – and the site will return a list of the suppliers that fit the bill.
To attract the right clients, developers can showcase an unlimited number of apps, brought to life with video, screenshots and plenty of supporting information.
Stuart Bluman, Co-Founder of AppBooker says “The service has received great feedback so far, and we’re now looking to welcome even more developers into our growing community.
As a thanks for helping us test the site, any developer that gets their profile live before midnight BST on Sunday 26th June will get three months free at our highest account level – worth $99 / month.”
Bluman continues “The AppBooker team will be going out all guns blazing to marketing agencies, brands and other key decision makers to raise awareness of the service when we launch later this month, so now’s the time to get on board.”
To redeem the offer, developers can create an account at www.appbooker.com using the following Invite Code:
You’ve built web apps and mobile apps (and probably even mobile web apps), but have you ever wondered how the technology differences between the traditional web and mobile web are affecting how your app runs?
The 2 biggest issues that affect mobile users today are the network (how the data gets to their phone), and battery life. Simple optimizations to your application can improve both of these issues noticeably for your users.
Background: Latency
Mobile networks have limited bandwidth and high latency compared to WiFi and broadband. Mobile networks take 100-1000x LONGER to initiate a TCP connection over traditional connections. The first connection to the internet requires phone radio-tower-internet connections, which can take up to 2 seconds! This is something that you (and your users!) notice.
Because of this high latency, mobile operators have invoked a state machine to all connections.
Wireless State Machine
What’s a state machine? Since that first connection took 2 seconds to establish, the network keeps the radio connection between the device and network open in a high power/high bandwidth state for several seconds after the last packet is sent (in case more data comes in). If a new TCP connection is established in this timeframe, it only takes 100-200ms to establish (still not as fast as broadband or WiFi, but still noticeably faster than 2s). After a period of inactivity, the network drops to a lower bandwidth/energy shared channel, and if no data comes in – eventually the radio connection times out and is closed.
Basically the state machine keeps the radio network open for a set period of time whenever it is opened in an attempt to ‘hide’ the connection latency in frequent connections. The timers in the state machine run a delicate balance to keep connections open and flowing – but also not draining the battery excessively.
So what do I do?
When architecting your application, you should consider the state machine. Every connection your application makes adds latency to your customers and drains their battery. Think of the battery life as a valuable resource for your customers – you want to minimize your impact. By reducing the number of connections and maximizing the use of each connection, your app will appear faster to users, and also drain the battery less.
In future posts, I will detail several best practices for application optimization that we have discovered while working with the state machine. For more details on the wireless state machine and how to make your application more energy efficient, you can read an article recently published by AT&T Research Labs.
Will the iPad 3 be launching in the fourt quarter of this year?
Three people have been arrested in relation to the iPad 2 leaks earlier this year.
Gizmodo has a nice iPhone 5 rumor roundup.
A bill has been introduced by US Senators Al Franken and Richard Blumenthal to enforce mobile privacy laws on the likes of Apple and Google.
Next generation iPad / iPhone GPU licensed to other manufacturers.
To start off with, Apple announced iOS 5 this week. Here is a list of features.
It looks like iOS 5 will run just fine on the iPhone 3GS. If you have not already check out the video we posted yesterday.
Does the fact that the ‘iPod’ icon is changing to ‘Music’ in iOS 5 mean Apple is ditching the iPod?
Apple registered at least 50 new domain names on 6/6/2011, the day of WWDC. A good sign of what is to come.
Apple has modified the in-app subscription policy that says in-app subscriptions must be sold at the same price as outside the app.
A few months ago NVIDIA started it’s Kal-El project to make quad-core processor, successor of Tegra 2 Dual core super chip – as the world’s first mobile quad-core processor for Next generation Android Smartphone. Kal-El processors will provide long battery battery life, powerhouse of a quad-core processor with a 12-core NVIDIA GPU with 3D stereo support. Rumor suggest that this Monster will be equipped in Next Google Phone Nexus 3 and expected to hit Market sometime this winter.
If you wonder how quad-core Kal-El processor will perform then here we go, Nvidia just published a nice Video demo of NVIDIA quad-core Kal-El projects which shows off all it’s glory. No more blah blah, watch the demo below and judge yourself.
The project is still in development and demoed on Honeycomb. We are expecting Kal-El processor will sport on Ice Cream Sandwich as Google confirmed the next of Android will merge Smartphone and Tablet later this year. After optimisation the final product will boast the performance 25%. Stay tuned with us at Facebook and Twitter to keep yourself updated on latest NVIDIA quad-core Kal-El processor. source.
It appears, as reported by various on-line news blogs, that Google (the search engine giant) will be rolling out Mobile Payment Service on May 26 using NFC(Near Field Communication).
![NFC Google Sprint 311x380 Google Mobile Payment Service to debut on May 26 Using NFC [Rumor]](http://www.tecrux.com/wp-content/uploads/2011/05/NFC-Google-Sprint.png "NFC-Google-Sprint")
This is a big news for the users of Sprint Nexus S 4G users as they’ll be saying bye bye to Credit Cards once they have this service on. The NFC service shall allow users to both pay and use mobile coupons with a swipe of their phones. According to Bloomberg, Google may officially announce this in a press event set for May 26th. The initial launch is rumored to include five cities – New York, San Francisco, Los Angeles, Chicago, and Washington D.C.
It seems that Google and Sprint’s combine offering will see some competition from ISIS, a joint effort between AT&T, Verizon, and T-Mobile. Apparently, the service will initially be only for the Google Nexus S 4G consumers. If you are one such user, would you use Google + Sprint service or would you use plain old Credit Card?
