Startup Sesame –  a field report

Startup Sesame –  a field report

What is Startup Sesame?

Startup Sesame is a one-of-a-kind program that connects European founders to European event organizers, bringing startups to amazing events throughout the year. While the exposure to events is great on its own, what’s even better is the network, on-site intros and especially the team behind it: Ben Costantin and his crew (@startupsesame).

Why Startup Sesame?

As a startup, you usually cannot afford to go to many conferences; however, a well-planned event can give you media exposure, great connections, sales leads, new ideas and generally provides you with learning opportunities along the value creation chain of your startup (from customer experience, networking, to closing a deal). It also gives you a great “reason for reaching out”. Yet, filtering out tons of events and which to attend, researching and planning the event in advance, and then performing on site and catching up with everything afterwards is a lot of work. Having a partner like Startup Sesame that helps you navigate that jungle, getting in touch with people on site, and last but not least with the financial costs, is invaluable. Even more, Startup Sesame not only sponsors most event tickets, they also provide additional opportunities to make use of the occasion like e.g. competing in the pitching competition, having a booth.

How does Startup Sesame work?

First of all, you need to apply.

Then, if you are selected, you are invited to a starting weekend where you get to meet

Then during the weekend, you get educated about the current startup ecosystem, the events, trends and most importantly the opportunity to pitch and get feedback on your pitch.

Panel discussion at the Sesame Summit 2018

This weekend allows the Sesame team and the startup organizers to get to know you and your business. This way, they can learn how to best help you and make unique recommendations on events and competitions to apply to. It also gives you the opportunity to understand what VCs and event organizers are looking for in startup competitions and on-stage talks, which events make sense for you, and how to go about these opportunities to really make use of them for the business. It also helps you refine your pitch.

After the weekend, you receive additional feedback and mentoring and then, during the following year you are presented (actively!) with event opportunities that match your startup and personality. Also, they assign #rockstar #mentors to you that help you make the most out of your event attention on site.

Startup Sesame Cohorte Retreat

Every year is organized differently. In our 2018 cohorte the setting was special: We were spending the time all together in shared rooms in a youth hostel at the Valencian beach. Food and coffee was a bit restricted, so we all needed to share and pay attention to each other’s needs. This brought the cohorte closer together than I think would usually have been the case (also great for the more introvert people… :D).

Who is Ben?

Ben is the founder and leader of Startup Sesame. Ben’s superpower is connecting people, or rather the right people; people who can benefit from being connected. Ben has a big heart, is very kind, and I believe he truly enjoys helping founders — and this really is what shapes the spirit of Startup Sesame. I am grateful to be part of the Startup Sesame Family (#proudsesamer).

Is it worthwhile?

For ObjectBox the answer is Yes. Once the next applications open I can only encourage you to apply. Just one word of warning: They give you tons of opportunities and in all likelihood, you can’t handle them all. E.g.: We needed to be very selective due to time constraints and it was/is hard to see many great opportunities pass by unused. However, you can check out what the #proudsesamer of 2018 have achieved in the last months on @startupsesame — it’s impressive and entertaining. 😊

These are the kind of events that you can attend as part of Startup Sesame. It was a great experience and lots of fun, but also added great value to our fundraising.

Or, if you are at dmexco 2018 or SaaStock 2018, you can join my talk on Open Source and Edge Computing. We can meet up there too 🙂

Let’s dive into the iOS World

Let’s dive into the iOS World

Two days ago, we attended the Swift Lighting Talks Meetup in Munich for the very first time. We had beer, pizza and listened to Sebastian Sellmeier’s presentation on making programming accessible and Denis Grebennicov’s presentation on the process of developing a Document Scanner app. It was fun and very instructive, thanks!

We also gave a 15 minute sneak peek talk about our ObjectBox iOS binding. Markus covered the basics of ObjectBox before sharing how we managed to overcome iOS constraints in our APIs. Finally, he disclosed the first (early) performance benchmarks on iOS, which we think are quite encouraging…

Check out the full talk in the video below.

In case you want to learn more about ObjectBox on iOS, sign up here for news and Early Access.
Special thanks to Stefan Mayer-PoppThe Munich iOS Developers Meetup for organizing this event and to Mayflower for hosting it.

 

We officially released our YouTube channel, we will post videos about ObjectBox and Tech in general. Subscribe to stay tuned.

 

ObjectBox 1.0

ObjectBox 1.0

ObjectBox 1.0 is a SQLite database replacement. It makes object persistence on mobile (and IoT) devices simple and fast.

Code actually tells best what ObjectBox does (yes, it also does Kotlin):

Don’t get us wrong: we think SQLite is a great piece of software and SQL is really powerful. We just do not love touching SQL so much when developing apps. That’s why we developed a very fast and easy alternative.

Being lazy or eager? Relations

ObjectBox comes with strong support for relations. How do you store a new object along with referenced objects? It’s simple:

Thus, with a single put(playlist), ObjectBox will not only persist the Playlist object but also the two associated Song objects. This also works with objects that were already persisted in the database.

A common challenge with relations is that they are typically loaded lazily. This can cause brief delays when accessing a relation for the first time, because the data must be pulled from the database at that moment. This in turn can cause the UI to slow down, e.g. when scrolling through the list (known as the “N+1 query problem”). Obviously, this may be harmful to the user experience and thus something you try to avoid. That is one of the reasons some ORMs do not support relations at all.

ObjectBox solves this challenge by enabling queries to preload relations in the background – aka “eager loading”. This makes processing the query result in the main thread super fast. Once the query is processed, eagerly loaded relations do not touch the database at all.

Eager loading is part of the Query API and not the entity itself. This gives you full flexibility over when to load what. For each query, you can specify which relations to preload like this:

POJOs

We want to keep things simple. The objects returned from ObjectBox are POJOs (plain old Java objects). When you get an object, all properties are initialized and ObjectBox will never change the values. And, of course, you can pass those objects around in different threads.

Let’s also have quick look on entity classes. First, ObjectBox does not enforce a specific base class. You are free to extend from any class. Second, the classes also define the data model in the database (the “database schema”). Adding and removing entities/properties just work. Only renames require your interaction. The days of CREATE TABLE scripts are finally gone, and typical data model updates do not require migration scripts.

Fast

We keep saying ObjectBox is fast. But how fast? And for what? We put together an open source benchmarking app, which come with a couple of performance tests for CRUD, queries, etc. Please check it out, have a look at the code, and make up your mind on the performance of ObjectBox. We really want to provide fair benchmarks.

Thank you!

A big thank you goes out to everyone who helped us in our beta phase (e.g. reported GitHub issues, blogs, …). It was only with your help that we reached version 1.0 now! As a special sign of appreciation, we’ll send out exclusive “early adopter” ObjectBox T-shirt: just write to us (contact@… – our domain) by September, 15th, with a link to your contribution along with your size and address.

We will add each and everyone that supports us and is part of the ObjectBox journey on our About us page! ObjectBox really is about you. So, let us know how you contributed (small things sometimes matter most…) and send us your picture and link (e.g. to your GitHub Account, Website or LinkedIn page).

Roadmap: bring your app to the edge

Our vision for ObjectBox is edge computing. It brings the data back to the user, to the device in his hand or home. We believe this is the future of computing. Small devices are tremendously powerful now, and it’s time to claim independence from the cloud while keeping in touch.

Before we go all edgy, we will address some essentials: Our plan for Version 1.1 is to rework the query API to and make expose object link API (aka “joins”). We also have to do our homework with some corner cases for data model changes. And of course, you may still find rough edges with the 1.0, which we’ll get rid off as soon as possible. We are dedicated to make ObjectBox a pure pleasure to work with.

We’re continually looking for feedback. Please do let us know what you think about ObjectBox: either by writing us at contact@… (our domain), or by answering these quick questions. Thank you!

Loading data.
In just 2 lines.

LOADING DATA FROM A MOBILE DATABASE

Loading data in a Mobile App can be lenghty… if you work with SQLite directly. That’s why we built the fastest ORM on the market: greenDAO. With greenDAO its only 2 lines of code. With ObjectBox, our Mobile Database, its also 2 lines of code. Objectbox simply gives you additional speed out of the box. If you are already working with greenDAO, you can switch to using ObjectBox almost seamlessly. Check out our greenDAO CompatLayer to learn how you can easily switch and boost your app performance with minimal effort.

CODE COMPARISON

SQlite / greenDAO / ObjectBox

SQLITE DATABASE

String[] columns = { “note”, “date_changed” };

String[] idArgs = { String.valueOf(id) };

SQLiteCursor cursor = (SQLiteCursor) db.query(“notes”, columns, “_id=?”, idArgs, null, null, “note”);

try {

if (cursor.getCount() != 1) {

throw new Exception(“Unexpected count: ” +cursor.getCount());

}

cursor.moveToNext();

String note = cursor.getString(0);

String date = cursor.getString(1);

updateUi(note, date);

} finally {

cursor.close();

}

GREENDAO ORM

Note note = noteDao.load(id);

updateUi(note.getNote(), note.getDate());

OBJECTBOX DB

Note note = noteBox.get(id);

updateUi(note.getNote(), note.getDate());

ObjectBox 0.9.10 – getting closer to 1.0

ObjectBox 0.9.10 – getting closer to 1.0

ObjectBox 0.9.10 - getting closer to 1.0

Do you know our new super fast mobile database ObjectBox yet? With versions 0.9.9 and the just released 0.9.10, ObjectBox made great progress to stabilize features for the 1.0 release. With an increasing number of apps using ObjectBox, we were able to spot and fix some less obvious issues. We believe that ObjectBox 0.9.10 is the most stable release ever. If you did not dare to check out the beta version yet: now is a good time to have a closer look.
