Google I/O 2016 developer talks

Last May 18th to 20th was the Google I/O 2016. The Google I/O is an annual conference for developers. Besides the usual marketing numbers, the keynote is often used to announce new products and services Google is planned to launch later this year. This year Google announced Google Home, a new messenger app Allo, a video calling app Duo and more. Besides these announcements, there are also a lot of interesting talks where Google developers tell us about how to use new, improved and existing APIs. A lot of those talks are available on Youtube. Below is a list of talks that I watched and found interesting enough to share.

The talk below is about using the right APIs to prevent your app to slow down the users phone or to drain the battery.

The talk below is about changes that were introduced in Android Marshmallow and Android N and other good practices to keep in mind to secure data in your app.

The talk below is about the new Awareness API. There are already numerous APIs that can detect the users’ activity, geofencing, whether the headphones are plugged in and more. Combining these APIs can be difficult, especially in terms of efficiency. The Awareness API efficiently combines the aforementioned APIs.

The talk below is a deep dive into the RecyclerView.

The final talk I would like to share is a deep dive into Fragments.

Interessante onderwerpen tijdens jaarcongres Topsector Logistiek

Vrijdag 22 april was het jaarlijkse congres van de topsector logistiek. De Amsterdam Arena was een prettige omgeving voor de plenaire sessies. Ook op het ‘experience plein’ waren verschillende sessies, waaronder van KPN over de uitrol van hun Low Power Long Range netwerk voor Internet of Things toepassingen. Wij waren natuurlijk blij dat KPN ons product Babbler als voorbeeld gebruikten.

Black Swan at IoT TechDay 2016

Two ‘things’ stood out firmly today at the IoT Tech Day 2016 in Utrecht. Both are potentially disruptive in nature. Ironically they are disruptive for precisely the ‘disruptiveness of IoT’ we all start to believe is actually upon us today.

First a simple but nonetheless scary observation: there is too much contention for space in the 2.4Ghz radio bandwidth range. Not just WiFi access points – 802.11b, 802.11g and 802.11n – flood the spheres but also BlueTooth devices, car alarm systems, microwave ovens, DECT phones, ZigBee devices and even home video broadcasts tend to talk heavily and loud in this part of the spectrum. So if you want to make sure that your connected thing will be able to deliver its data or collect its commands in a timely and disruption-free fashion you will have to connect your thing elsewhere. The 5Ghz range is still relatively quiet but the question remains, for how long? And what if every Bob and Alice start to connect all their gear and flood the available space?

The Dutch Radiocommunications Agency, the national expert in (and enforcer of) the regulation of bandwidth use, does not know. And they are proud to admit to their lack of insight. At this point they are not even sure if certain parts of the frequency ranges should be regulated or not. They are however currently creating scenario’s that will help them draft up policies for future regulation. These scenario’s will be based on rational and logical combinations of plausible but yet unknown variables. How many devices, what type of communication, what density of connections, which networks? Coming September they will publish their findings.

Why they do not know, you ask? Because they believe they – and we, the IoT practitioners – have stumbled upon a ‘black swan’ (Look for Nassim Taleb’s The Black Swan, The Impact of the Highly Improbable). An animal so rare that it upsets all our previous observations and calculations. A highly disruptive animal because it challenges the expertise of the experts. So our Radiocommunications Agency’s advice is as simple as it is dumbfounded: “Do not trust the expert in this matter”. Try to figure it out for yourself by experimenting, joining forces with others, by failing fast and moving on.

Laughable as this might seem, they do have an excellent point: IoT in it’s current shape is unfinished business. A lot of data, yes. A lot of potential, sure. A flurry of technical excitement, absolutely. But all of this to no clear end. There are no killer apps for IoT, yet. Maybe this is an advantage, actually. If you can find a well defined problem, if you are willing and able to imagine a fitting approach toward a solution. Then you might have your killer app sooner than expected. We tend to help with that. Join us and let’s create your own scenario’s.

Visit us at Fruit Logistica 2016 in Berlin

FL2016-logo-en-v2

We will be demonstrating Babbler between 3 and 5 February at the Fruit Logistica 2016 in Berlin. Fruit Logistica attracts over 60.000 visitors every year, with over 2800 exhibitors. Please drop by if you are visiting and try to enter our shipping container without being detected!

We are at Hall 21 stand F04 (EU-FINISH).

Fresh apps on tour

The EU Fresh Info is a two day innovation event for companies involved in fresh produce.

Among those to share their insights were: The Port of Rotterdam, Copenhagen Business School, Jumbo supermarkets, Albert Heijn supermarkets, Univeg, Frugi Venta, Fruitday and SanLucar. Itude Mobile exhibited on both days and presented our smart seal product during the breakout sessions on Wednesday.

Some highlights:

  • Good news for dutch exporters: In China, nobody trusts domestic produce, which is creating a massive market for online purchase of fruit and vegetables.
  • Paper shipping documents are expensive; two thirds of the cost of international transportation by shipping container is due to (paper) documents.
  • Data sharing initiatives around the Port of Rotterdam are blossoming; Container Monitor and the use of Global Location Numbers for port berths will make life easier for carriers in the Rotterdam area.
